Description

Connectors for flexible substrates

technical field

The present invention relates to a connector for a flexible substrate that is wired and connected to, for example, a control board of a device. More specifically, it relates to a connector for a flexible substrate that can achieve miniaturization by improving the connection structure.

Background technique

Generally, as shown in FIG. 19, this kind of connector for flexible printed circuit boards has a mounting opening 193 on the front side of the housing 191. In order to insert and install the conductive front end portion of the flexible printed circuit board (FPC) 192, a A plurality of connectors 194 are arranged in parallel inside 193, which are in contact with and fixedly connected to the conductive front end of the flexible substrate. The outside is slid into the installation opening 193 as if the slider 195 is inserted, and the conductive front end portion of the flexible substrate 192 is pressed against the contact portion 194a of the connector 194 and connected and fixed as one.

Furthermore, when the assembled connectors 194 are arranged side by side in the housing 191, each connector 194 is press-fitted and fixed in each connector press-fit groove 191a formed in parallel on the rear side of the housing 191. Install.

Furthermore, as shown in FIG. 20, when the connector 202 is pressed in and fixedly installed at the front and rear of the housing 201, the connector 202 can be pressed in and installed from the front and rear direction of one housing 201, because the housing 201 can be The outer end 202a of the connector 202 is taken out from the substrate 203 in both front and rear directions, so it has the advantage of being convenient for wiring and connection to the substrate 203, and can further promote the miniaturization of the connector.

However, when promoting the miniaturization of connectors for flexible substrates, as shown in FIG. 21 and FIG. The parallel pitch of the connectors 212 is made as narrow as possible.

Therefore, when the thickness of the connector is reduced, the connector itself loses its elasticity and cannot secure a stable contact force with the flexible substrate. In addition, when the narrow pitch of the connectors is promoted, the resin layer 213 between the connectors will also be thinned, and the mold parts will be too thin during the resin molding of the shell, which is easy to be damaged. Thinning of the resin layer 213 may result in insufficient filling of the resin and easily cause molding failure.

Furthermore, as shown in FIG. 23, the connectors 232, 233 are pressed and fixed from the front and rear directions of the housing 231, and the contact portions of these connectors 232, 233 are all formed into a lower contact type to achieve miniaturization. This is well known. (For example, refer to Patent Document 1 and Patent Document 2). In the figure, 234 is a slider, and 235 is a flexible substrate.

However, in order to ensure the insulating distance between the front, rear, left, and right connectors, avoid the thinning of the connectors, and ensure the spring length of the connectors in the longitudinal direction so that the connectors themselves have stable corresponding contact performance, the length of the connectors must be lengthened to make the connectors smaller. Difficulty.

Furthermore, as shown in FIG. 24 , the front connector 242 and the rear connector 243 are arranged opposite to each other in the front and back direction of the housing 241, so that the front connector 242 constitutes the lower contact 242a, and the rear connector 243 constitutes the upper contact 243a. It is well known to form upper and lower contact types (for example, refer to Patent Document 3, Patent Document 4).

However, in this case, in order to correspond to the upper and lower contacts, it is necessary to provide conductor portions on both the front and back surfaces of the end portion of the flexible substrate, which increases the price of the flexible substrate. In addition, since the contact part is divided up and down, it becomes a complex structure in order to apply to the ZIF type contact structure in which the conductor part at the end of the flexible substrate is pressed against the upper and lower contacts by using a pressing member such as a slider or a lever. . In addition, it is necessary to ensure insulation distances between the front, rear, left, and right sides of the connectors arranged in parallel in the housing, and there is a limit to miniaturization in reality.

Contents of the invention

Here, the object of the present invention is to provide a connector for flexible substrates as follows: by distributing and distributing a plurality of connectors assembled in the housing to form a zigzag shape both in the plane and in the height direction, the connectors can be ensured. There is an appropriate insulation distance between them, and it is easy to manufacture and can form a miniaturized connector for flexible substrates.

The present invention is a connector for flexible substrates, wherein an insulating case is provided, and a mounting opening for flexible substrate mounting is opened on the front side, and a flexible substrate and a flexible substrate are arranged in parallel in the left-right direction inside the mounting opening. The conductive front end portion of the housing is in contact with and connected to a plurality of fixed connectors; the arrangement positions of the connectors arranged side by side in the above-mentioned left and right direction are divided into two rows on the front row side and the rear row side of the above-mentioned housing, and the front and rear two rows are arranged in the plane direction. Each link of the row becomes a zigzag shape, and at the same time, it is also divided into two rows on the upper side and the lower side in the height direction. The outer ends of the connectors on the side protrude on the front side of the housing, and the outer ends of the connectors on the rear row protrude on the rear side of the housing.

Here, the flexible substrate is a strip-shaped electrical wiring in which a plurality of wirings are arranged in parallel on a flexible insulating material to be integrated.

The mounting port is a horizontally long opening formed by opening on the front surface of the case, and allows insertion of a strip-shaped flexible substrate.

The above-mentioned connector is made of conductive material, the inner end is installed in the housing corresponding to the position contacting the flexible substrate, and the outer end is electrically connected and fixed on the substrate outside the housing.

The above-mentioned casing allows a plurality of connectors to be distributed and assembled in a zigzag shape inside, and can be formed by mold molding of a synthetic resin suitable for insulation.

According to the present invention, because the front and rear two rows of connectors in the left and right directions of the housing are not only scattered in the plane direction but also in the height direction, they are arranged in a zigzag shape, so the connectors form a three-dimensional zigzag configuration in the housing. The distance between connectors can also be lengthened in the left and right as well as in the up and down directions.

Therefore, even if the connector for a flexible substrate is downsized, it can be arranged and formed to ensure an appropriate insulation distance between the connectors. In addition, the resin layer between the linkers can also avoid the thin material part and ensure the thickness suitable for shell making. Therefore, there is no thin part in the mold part, and a durable mold that is hard to break can be obtained, and it is also easy to manufacture, and further miniaturization of the casing can be promoted. In addition, because the thinning of the connector can also be avoided, the elasticity of the connector itself will not be lost, and it has a stable elastic contact force, which can ensure the contact pressure with the flexible substrate and improve the contact with the flexible substrate. reliability.

Furthermore, since the insulation distance between the connectors can be extended not only in the left, right, front, back, but also in the up and down directions, insufficient resin filling between the connectors can be avoided, and a stable finished product can be obtained. Furthermore, the connectors of the front and rear rows are arranged in a zigzag shape no matter in the plane direction or in the height direction, and because the front and rear directions are not opposite, the longitudinal spring length of the connectors can be extended in the front and rear directions of the housing. Therefore, each linker can be provided with stable contact performance.

Another aspect of the present invention is a connector for flexible substrates. An insulating case and an insulating pressing member are provided, and a mounting port for mounting a flexible substrate is opened on the front side of the insulating case. A plurality of connectors that are in contact with and fixedly connected to the conductive front end of the flexible substrate are arranged in parallel in the left and right direction inside the installation port. The insulating pressing member allows the advance and retreat toward the interior of the installation port, and presses the conductive front end when advancing. On the connectors on the opposite upper side or the lower side, the pressing force is released when retreating; row, and in the plane direction, the connectors of the front and rear rows are arranged in a zigzag shape, in which the outer ends of the connectors on the front row side protrude from the front side of the housing, and the connectors on the rear row side The outer end protrudes on the rear side of the housing, wherein the connectors arranged in a zigzag manner in the above-mentioned planar direction are also divided into two parallel rows on the upper side and the lower side in the height direction of the housing, and The connectors in the upper and lower columns are also arranged in a zigzag shape in the up and down direction.

The pressing member here is an insertion member that integrally presses, fixes and installs the flexible substrate inserted and installed in the mounting port of the housing, and is constituted by a slider that can slide in the front-rear direction of the housing or a lever that can be rotated. .

In this case, because the distance between the front, rear, left, and right, and up and down connectors can be lengthened, the thin material part of the housing can be avoided and an appropriate insulation distance between the connectors can be ensured, so the flexible substrate connector can be formed in a small size. change. In addition, if the conductive front end of the flexible substrate is pressed against the facing upper or lower connectors by the pressing member, the corresponding contact can be easily made, and it can be applied to a single-sided economical one-sided contact on the upper or lower side. flexible substrates.

As another embodiment of the present invention, the connector is press-fitted from the front-rear direction of the case, fixed, and attached to form a connector for a flexible substrate.

In this case, since the connectors are mounted in a zigzag pattern on the front and rear sides of one housing, the outer ends of the connectors can be distributed and taken out front and rear. Therefore, sufficient wiring connection space on the board can be obtained, and the miniaturization of the connector for flexible boards can be promoted.

As another embodiment of the present invention, a connector for a flexible board is configured by press-fitting, fixing, and mounting one-row connectors arranged in two rows on the front side and the rear side of the case from above the case.

In this case, since one of the connectors can be press-fitted from the upper side of the case, it can be press-fitted as it fits into the case. For example, in the case of a planar case, the pressing operation can be performed from the upper surface having a wide area suitable for the pressing direction. Furthermore, the connector has a shape that is long in the front-rear direction and short in the up-down direction, and since it is pressed in from the short direction, the press-in distance is shortened and stable mounting is achieved.

As another embodiment of the present invention, a connector for a flexible board is configured by press-fitting, fixing, and mounting one-row connectors arranged in two rows on the front row side and the rear row side of the casing from below the casing.

In this case, since one of the connectors can be press-fitted from the lower side of the housing, it can be press-fitted according to the fitting into the housing. For example, in the case of a planar housing, the press-fit operation can be performed from the bottom surface with a wide area suitable for the press-fit direction. Furthermore, the connector has a shape that is long in the front-rear direction and short in the up-down direction, and since it is pressed in from the short direction, the press-in distance is shortened and stable mounting is achieved.

As another embodiment of the present invention, all the contacts on the connector that are connected, fixed and conducted with the conductive front end of the flexible substrate are set on the upper side of the hollow part in the housing to form a connection for flexible substrates. device.

In this case, since the contact points of the connectors are aligned on the upper side, only by pushing up the pressing member, the conductive front end of the flexible substrate can easily correspond to the connectors, and can be applied to single-sided contacts corresponding to the upper side. economical flexible substrate.

As another embodiment of the present invention, it is possible to set all the contact points on the connector that are connected, fixed and conducted with the conductive front end of the flexible substrate on the upper side of the cavity in the housing, and make the contact points The height and position of the connectors are consistent to form a connector for flexible substrates.

In this case, since the height positions of the contact parts are aligned on the upper side, the pressing direction of the pressing member and the shape of the pressing member are not complicated, and the shape of the pressing member is simplified.

Detailed ways

Embodiments of the present invention will be described in detail with reference to the following drawings.

Example 1

FIGS. 1 and 2 show a connector 11 for a flexible substrate including a housing 12 , a front connector 13 , a rear connector 14 , and a slider 15 .

The housing 12 used here is formed into a flat plate using a resin material suitable for insulation, and has an installation port 17 opened horizontally in the front of the housing 12, which is used to connect the flexible substrate 16; 17 communicates with a cavity 18 for connecting a flexible substrate.

In addition, on the front side of the housing 12 communicating with the mounting port 17 and the hollow portion 18, front press-fit grooves 19 are formed side by side at regular intervals in the left-right direction of the housing 12, which are used to respectively press-fit and fix the front. Linker 13.

Further, on the rear side of the case 12, as shown in FIG. 3, rear press-fit grooves 20 are formed side by side at regular intervals in the left-right direction of the case 12, and are used to press-fit and fix the rear connectors 14, respectively.

In this case, as shown in FIG. 4, the arrangement positions of the front press-fit grooves 19 and the rear press-fit grooves 20 that are arranged side by side at a certain interval in the left-right direction are divided into two rows in the front and rear of the housing 12, and the front and rear sides are aligned in the front-rear direction. The press-in grooves 19, 20 are not opposed to each other in the planar direction of the housing 12. The press-in grooves 19, 20 are arranged in two rows in a zigzag shape. At the same time, they are also divided into upper parts in the height direction (thickness direction of the housing). The front and rear press-fit grooves 19 and 20 are arranged in a zigzag shape so that the front and rear press-fit grooves 19 and 20 are not opposed to each other in the two rows of the side and the lower side.

Front and rear connectors 13 and 14 to be described later are press-fitted and fixed into these front and rear press-fit grooves 19 and 20 to be integrally assembled with the casing 12 . Then, as shown in FIG. 5 , the slider 15 is slidably mounted in the mounting opening 17 of the housing 12 to form a standby state waiting for the flexible substrate 16 to be mounted.

In this case, since the connectors 13 and 14 arranged in front and rear two rows in the left-right direction of the housing 12 are scattered and arranged in a zigzag shape not only in the planar direction but also in the up-down direction, the connectors are arranged in a three-dimensional zigzag shape inside the housing. Therefore, the distance between the distributed connectors can be lengthened not only in the front, back, left, and right directions but also in the up and down directions on the housing 12 . Therefore, even if the connector 11 for flexible boards is miniaturized, the insulation distance can be ensured, and the adjacent connectors will not interfere with each other or interfere with each other. Furthermore, since the thin portion of the resin layer 12a (see FIG. 4 ) between the connectors in the parallel direction can be eliminated, insufficient filling of the resin is eliminated, and resin molding of the case 12 is facilitated. Therefore, there is no thin material part in the mold parts for shell molding, and a durable mold can be obtained. In addition, because the resin 12a between the linkers is guaranteed to be of a certain thickness, the thinning of the material can be eliminated, and the thinning of the linker itself can be avoided, the elasticity of the linker itself will not be lost, and the linker itself has stable elasticity. The contact force with the flexible substrate 16 can ensure the contact pressure with the flexible substrate 16, and the contact reliability with the flexible substrate 16 can be improved.

In addition, because the connectors of the front and rear rows are scattered in a zigzag shape no matter in the plane direction or in the height direction, it can be arranged in a direction that is not opposite to each other in the front and rear directions, and has a sufficient length in the front and rear directions of the housing. Elastic linker. Therefore, since the contact portion of the connector can also be supported on one side for a long time, the spring length of the contact portion of the connector can be extended. Therefore, stable contact properties can be imparted to the contact portion.

The above-mentioned connector 13 is designed in a long J-shape, and is installed in the front press-in groove 19 from the front side of the housing 12 in the state of laying flat along its longitudinal direction. As shown in Figure 6, the front connector 13 An upper contact portion 13 a is formed at the inner end portion of the J shape, and the upper contact portion 13 a is interposed on the upper side of the hollow portion 18 . Furthermore, the outer end portion 13b of the front connector 13 protrudes from the front side of the housing 12 to the front outer side.

The above-mentioned rear connector 14 is designed in a long U-shape, and the connector 14 is placed horizontally along the longitudinal direction of the U-shape, and is installed by pressing into the groove 20 from the rear side of the housing 12, as shown in FIG. 7 , The upper inner end portion of the U-shape of the rear connector 14 is formed with an upper contact portion 14 a interposed on the upper side of the hollow portion 18 . Furthermore, the outer end portion 14b of the rear connector 14 protrudes from the rear side of the housing 12 .

The outer ends 13b, 14b of these connectors protrude outside the housing 12, and when the housing 12 is installed on the control board, they are electrically connected to the circuit on the board. Furthermore, since the connectors 13, 14 are pressed in from the front and rear of the housing 12, fixed and installed, the outer ends 13b, 14b of all the connectors are dispersed in a zigzag pattern at the front and rear of the housing 12 and taken out. Therefore, sufficient connection space can be obtained at the time of wiring on the substrate.

Furthermore, the slider 15 is made of an insulating resin material, and is allowed to slide toward the inside of the mounting opening 17 opened on the front of the housing 12, and has an anti-pullout engagement portion 15a and a sliding guide surface 15b on both sides of the front end. (Refer to FIG. 1 ), there is a stepped pressing surface 15c (refer to FIG. 7 ) on the central part, which makes the upper contact parts 13a, 14a of the connectors 13, 14 uniformly pressed into contact. Furthermore, there are press-fit stopper portions 15d on both sides of the rear end portion.

When connecting and fixing the flexible substrate 16 using the flexible substrate connector 11 configured in this way, as shown in FIGS. Simultaneously with the insertion operation, slide the slider 15 forward, so that the step pressing surface 15c on the slider pushes up the conductive front end to the upper side when advancing, and the upper contacts of each connector 13, 14 opposite to its upper side The parts 13a and 14a are in contact with each other and are electrically connected, and the mechanical pressing force of the slider 15 can maintain a stable contact pressure.

In this case, since the upper contact portions 13 a and 14 a of the connector are aligned on the upper side, it can be applied to a single-sided economical flexible substrate that contacts the upper side in the cavity 18 .

Furthermore, if the slider 15 is pulled back to the front outside of the housing 12, the upward pushing pressure of the slider 15 will be released, and the conductive front end of the flexible substrate 16 will be in a free state and can be removed. .

Example 2

As shown in FIG. 10 and FIG. 11 , the difference between the flexible substrate connector 101 of the second embodiment and the flexible substrate connector 11 of the first embodiment is that the pressing direction of the rear connector 104 is from The upper direction of the housing 102 is pressed down and the heights of the upper contact parts 103a, 104a of the front and rear connectors 103, 104 are consistent at the same height. Even if the housing 102 and the slider 105 have different shapes, they have the same function and can obtain the same effect, so only the differences are described.

The top press-in groove 106 of the above-mentioned housing 102 is arranged side by side on the upper rear side of the housing 102 in the left-right direction, wherein the long L-shaped rear connector 104 is pressed in and installed in a flat state.

In this case, as shown in FIGS. 12 and 13 , an upper contact portion 104 a is arranged on the L-shaped inner end of the rear connector 104 , and the upper contact portion 104 a faces the hollow portion 108 inside the housing 102 from above, between the upper side of the hollow portion 108 . Furthermore, the outer end portion 104b of the rear connector 104 protrudes from the rear side of the housing 102 . 104c is an anti-pulling sheet among the figure.

The outer ends 103b, 104b of these front and rear connectors protrude outward from the front and back of the housing 102, and when the housing 102 is installed on the control board, they are electrically connected to the circuit on the board. Furthermore, when the connectors 103, 104 are pressed in from the front and the top of the housing 102, fixed and installed in the front and rear positions of the housing 102, the connectors 103, 104 in the front and rear two rows parallel in the left and right direction will be In the planar direction of the housing 102 or in the height direction, they are scattered and arranged in a zigzag shape.

In this case, the connectors installed in the casing are arranged in a zigzag shape in both the planar direction and the height direction, so that they are installed in a three-dimensional zigzag configuration, and the same effect as that of the first embodiment can be obtained. In addition, since the rear connector 104 can be press-fitted from above the housing 102, it can be press-fitted from the wide upper surface of the flat-shaped housing 102, enabling suitable press-fitting for installation into the housing.

Specifically, when the connector is press-fitted into the case, the pressing area of the portion where the connector is pushed can be increased. Furthermore, there is an advantage that the shape of the jig used for press-fitting is simplified. Furthermore, since the long rear connector 104 is press-fitted in the short direction (height direction) of the case 102, the press-fitting distance is shortened and stable mounting can be performed.

Furthermore, because the upper contact portions 103a, 104a of the front and rear connectors 103, 104 can be aligned on the upper side, only the conductive front end portion of the upper flexible substrate 107 can be easily contacted by the slider 105. On the upper contact portion 103a, 104a of the connected child, it is suitable for a single-sided economical flexible substrate that contacts on the upper surface.

Furthermore, because the height positions of the upper contact portions 103a, 104a of the front and rear connectors 103, 104 can be formed in the same position on the upper side, the pushing direction of the slider 105 and the shape of the slider 105 will not be complicated. The shape of the slider 105 can be simplified by sharing the flat and simple push top surface 105a which is easy to manufacture.

In this case, the slider 105 has a box shape with its front and back open, and its lower surface is inserted through the front opening of the housing 102 to slide it. Since it is a box shape, it is easy to use. When connecting the flexible substrate 107 , because both end surfaces of the slider 105 can be held and slid with fingertips, a good connection operation can be performed. Furthermore, since the upper surface of the slider 105 can have a wide flat surface, the upper surface is suitable for use as a suction surface of a robot for assembling the connector, which facilitates assembly on the substrate.

Example 3

As shown in FIG. 14 and FIG. 15 , the difference between the flexible printed circuit connector 141 of the third embodiment and the flexible printed circuit connector 11 of the first embodiment is that the pressing direction of the front connector 143 is from The bottom of the housing 142 is pressed upward. The housing 142 and the slider 145 have different shapes but have the same function and can obtain the same effect, so only the differences will be described.

The lower pressing groove 146 of the above-mentioned housing 142 is arranged side by side on the lower front side of the housing 142 in the left-right direction, and the long J-shaped front connector 143 is press-fitted from below in a flat state and installed.

In this case, as shown in FIGS. 16 and 17 , an upper contact portion 143 a is provided at the J-shaped inner end of the front connector 143 , and the upper contact portion 143 a is interposed above the hollow portion 148 inside the housing 142 . Furthermore, the outer end portion 143b of the front connector 143 protrudes from the front side of the housing 142 . 143c is an anti-pulling sheet among the figure.

Furthermore, the front and rear connector outer ends 143b, 144b protrude outward from the front and back of the housing 142, and when the housing 142 is installed on the control board, they are electrically connected to the circuit on the board. In addition, when the front and rear connectors 143, 144 are pressed in from the bottom and rear of the housing 142, fixed and installed at the front and rear positions of the housing 142, the connectors 143, 144 in the front and rear two rows parallel in the left and right direction will be ignored. Whether in the planar direction of the housing 142 or in the height direction, they are respectively scattered and arranged in a zigzag shape.

In this case, the connectors installed in the casing are arranged in a zigzag shape in both the planar direction and the height direction, so that they are installed in a three-dimensional zigzag configuration, and the same effect as that of the first embodiment can be obtained. In addition, since the front connector 143 can be press-fitted from the bottom of the housing 142, it can be press-fitted from the wide underside of the flat-shaped housing 142, enabling suitable press-fitting for installation into the housing.

In this case, when the connector is press-fitted into the case, the pressing area of the portion where the connector is pushed can be increased. In addition, there is an advantage of simplifying the shape of the jig used for press-fitting. Furthermore, since the long rear connector 144 is press-fitted in the short direction of the housing 142, the press-fitting distance is shortened and stable mounting can be performed. Furthermore, since the long front connector 143 is press-fitted in the short direction of the housing 142, the press-fitting distance is shortened and stable mounting can be performed.

Furthermore, since the upper contact portions 143a, 144a of the front and rear connectors 143, 144 can be aligned on the upper side, the connectors can be easily contacted only by pushing up the conductive front end of the upper flexible substrate 147 by the slider 145. The upper contact portion 143a, 144a can be applied to a single-sided economical flexible substrate that contacts on the upper surface.

The upper contact portion 143a of the above-mentioned front connector 143 has a clamping contact structure that clamps the conductive front end portion of the flexible substrate 147 between the upper and lower surfaces when the flexible substrate 147 is inserted into the housing 142. In this way, Mounting workability of the flexible substrate 147 is improved.

In addition, the case where a rotary slider is used as an example of the slider 145 used is shown here. This rotary slider has the following structure: the lower part of the slider 145 is pivotally supported on the housing 142. The shaft supporting part 145a formed on the upper part is set on the pivot point of rotation. When the flexible substrate 147 is inserted, the slider 145 is rotated to make the flexible substrate 147 and the upper contact parts 143a, 144a of each connector contact firmly.

As mentioned above, because the front and rear two rows of connectors in the left and right direction of the housing are not only dispersed in the plane direction but also arranged in a zigzag shape in the height direction, the connectors form a three-dimensional zigzag configuration in the housing, not only in the front and rear The distance between connectors can also be lengthened in the left and right as well as in the up and down directions.

As a result, even if the connector for a flexible substrate is downsized, it can be arranged and formed to ensure an appropriate insulation distance between the connectors. Furthermore, it is possible to avoid the thin material part of the resin layer connecting the sub-units and ensure a thickness suitable for housing production. Therefore, there is no thin material part in the mold part, and a durable mold that is hard to break can be obtained, and it is also easy to manufacture, and further miniaturization of the casing can be promoted. In addition, because the thinning of the connector can also be avoided, the elasticity of the connector itself will not be lost, and it has a stable elastic contact force, which can ensure the contact pressure with the flexible substrate and improve the reliability of contact with the flexible substrate. sex.

In addition, since the insulation distance between the connectors is extended not only in the left, right, front, back, but also in the vertical direction, insufficient resin filling between the connectors can be avoided, and a stable product can be obtained. Furthermore, the connectors of the front and rear rows are arranged in a zigzag shape no matter in the plane direction or in the height direction, and because the front and rear directions are not opposite, the longitudinal spring length of the connectors can be extended in the front and rear directions of the housing. Therefore, each linker can be provided with stable contact performance.

In the correspondence between the structure of the present invention and the structure of the above-mentioned embodiment, the pressing member of the present invention corresponds to the slider of the embodiment, and the present invention is applied based on the technical idea expressed in the claims, and is not limited to the structure of the above-mentioned embodiment.

For example, in the above-mentioned embodiment, the contact parts of the connectors are set to be on the upper side, but it is not limited thereto, and the contact parts can also be formed on the lower side. In this case, only the orientation of the contact parts is different, but completely the same Effect.

According to the present invention, since the distance between the connectors can be extended and the connectors can be dispersed and arranged, even if the connector for a flexible circuit board is miniaturized, it can be arranged at intervals ensuring an appropriate insulation distance between the connectors. In addition, it is possible to ensure a thickness suitable for manufacturing the casing by avoiding the thin portion of the resin layer between the connecting elements. Therefore, there is no thin part in the mold part, and a durable mold that is not easy to break can be obtained, and it is also easy to manufacture and can promote miniaturization. In addition, because the thinning of the connector can also be avoided, the elasticity of the connector itself will not be lost, and it has a stable elastic contact force, thereby ensuring the contact pressure with the flexible substrate and improving the contact reliability with the flexible substrate. sex.
