Description

Connectors for cables and connectors for boards

The present invention relates to a cable connector in which the pulling out direction of the cable is set in a direction intersecting with the plugging and unplugging direction of the connector, and a board connector connected to the cable connector.

In the cable connector in which the pulling-out direction of the cable is set in a direction intersecting with the plugging and unplugging direction of the connector, there is an advantage that the cable and the board can be easily connected through the connector even when a large space cannot be secured above the board.

For example, consider the case of "mounting a board connector having an insertion hole opened above on the surface of a board placed horizontally, and inserting the insertion portion of the cable connector into the insertion hole of the board connector from above toward the bottom, and connecting the board connector and the cable connector." In this case, if a cable connector is used in which the pulling out direction of the cable is set in the same direction as the plugging direction of the connector, the plugging direction of the connector and the pulling out direction of the cable are both vertical directions. Therefore, when the cable connector and the board connector are connected, the cable extends upward from the board. Therefore, it is difficult to wire the cables in a situation where a large space cannot be secured above the substrate. On the other hand, when using a cable connector in which the direction of pulling out the cable is perpendicular to the direction of insertion and extraction of the connector, the direction of insertion and extraction of the connector is the vertical direction, and the direction of pulling out the cable is the horizontal direction. Therefore, when the cable connector and the board connector are connected, the cable is extended so as to follow the surface of the board. Therefore, in a situation where a large space cannot be secured above the substrate, it becomes easy to wire the cables.

In the following Patent Documents 1 and 2, there are described cable connectors in which the pulling out direction of the cable is set in a direction intersecting with the plugging and unplugging direction of the connector. [Prior Art Literature] [Patent Document]

[Problem to be solved by the invention]

In FIG. 3 of the aforementioned Patent Document 1, an electrical connector and a counterpart connector ( 20 ) connected to the electrical connector are described. As shown in the figure, the plugging direction of the electrical connector relative to the opposite connector (20) is vertical, and the pulling direction of the cables (C1, C2) installed on the housing body (1) of the electrical connector is horizontal. The electrical connector and the counterpart connector (20) are connected by fitting the contact element arrangement part (21) formed at the counterpart connector (20) into the receiving recess (7) formed at the protrusion (9) of the housing body (1) of the electrical connector.

However, the depth dimension of the receiving recess (7) at the electrical connector described in Patent Document 1 and the height dimension of the contact element arrangement portion (21) at the counterpart connector (20) are both small. Therefore, the fitting between the contact element arrangement part (21) and the receiving recess (7) is shallow, and the effective fitting length between the terminals of the electrical connector and the terminals of the opposite connector (20) is short. A connector with a short effective mating length has low durability against oblique pulling. For example, when the pull-out end side of the cable pulled out from the housing of the connector toward the horizontal direction moves toward the horizontal or vertical direction, thereby causing the connector to be pulled obliquely, the position of the connector will shift relative to the counterpart connector, and it may be difficult to maintain contact between the terminals of the connector and the terminals of the counterpart connector.

On the other hand, in FIG. 3 of the above-mentioned Patent Document 2, a coaxial connector provided with an L-shaped inner terminal (20) is described. The L-shaped inner terminal (20), as shown in FIG. 1 of this document, has a crimping part (22) that connects the core wire (2) of the coaxial cable (1) and a body part (21) that contacts the terminal of the opposite connector. The crimping part (22) is elongated toward the horizontal direction, and the body part (21) is elongated toward the vertical direction. In this way, when the terminals of the connector are formed in an L-shape, the effective fitting length between the terminals of the connector and the terminals of the counterpart connector can be increased by increasing the length of the vertically elongated portion, thereby improving the durability against oblique pulling.

However, if the terminals of the connector are integrally formed in an L-shape, it is necessary to have a structure in which the housing for accommodating the L-shaped terminals is divided into a plurality of parts. For example, in the coaxial connector described in Patent Document 2, as shown in FIG. 2 of the document, the part accommodating the L-shaped inner terminal (20) is divided into a cylindrical part (41) and a cover (60). When the housing body has a structure divided into a plurality of parts, it is necessary to assemble the parts constituting the housing when assembling the connector. Therefore, the number of assembly processes increases, and the workability of assembling the connector deteriorates.

The present invention, for example, has been made in view of the above-mentioned general problems. The subject of the present invention is to provide a connector for cables and a connector for substrates connected to the connector for cables. The connector for cables is a cable connector in which the pulling out direction of the cable is set in a direction intersecting with the plugging and unplugging direction of the connector, and the durability against pulling in an oblique direction can be improved, and the workability of assembling the connector can be improved. [means used to solve a problem]

The terminal is formed in an L-shape when viewed from the side by connecting the front end side of the first terminal piece elongated in the front-rear direction and the upper end side of the second terminal piece elongated in the vertical direction. The first terminal piece and the second terminal piece are separable from each other. A cable connection portion for connecting the cables is provided, a contact portion is provided at the lower end side of the second terminal piece to contact the opposite terminal of the counterpart connector, and a connecting portion for connecting the first terminal piece and the second terminal piece is respectively provided at the front end side of the first terminal piece and the upper end side of the second terminal piece. The right wall portion, and a terminal receiving portion formed in the housing to accommodate the terminals, the terminal housing portion is provided with a first terminal housing portion for housing the first terminal blade, and a second terminal blade housing portion for housing the second terminal blade, the first terminal blade housing portion is elongated in the front-rear direction in the housing, and the second terminal blade housing portion is inside the housing and extends downward from the front end of the first terminal blade housing portion, at the rear end of the housing. At the lower end of the housing, there is a terminal insertion hole communicating with the inside of the second terminal strip accommodating portion and used for inserting the counterpart terminal of the counterpart connector.

In order to solve the above-mentioned problems, the substrate connector of the present invention is a substrate connector mounted on a substrate, and is characterized in that it is provided with: a plurality of plate-shaped or bar-shaped terminals; The insertion recess into which the connector is inserted, the plurality of terminals are disposed in the insertion recess in a row in the front-rear direction, the base end of each terminal is supported by the lower plate, the front end of each terminal protrudes upward, and a partition plate is provided in the insertion recess for partitioning two adjacent terminals among the plurality of terminals.

On the other hand, when the first terminal strips 11 are inserted into the lower first terminal strip accommodating portions 41 at the housing 31, the locking protrusions 17 provided on the first terminal strips 11 face downward. The first terminal strips 11 inserted into the lower first terminal strip accommodating portions 41 are fixed in the lower first terminal strip accommodating portions 41 by locking the locking protrusions 17 in the lower locking holes 49 . Moreover, since the lower locking holes 49 pass through the lower wall portion 33, the operator who assembles the cable connector 1 can observe the housing 31 from below to confirm whether the locking protrusions 17 are locked in the lower locking holes 49, that is, whether the first terminal strips 11 are inserted into the first terminal strip receiving portion 41 disposed on the lower side and fixed.

Also, as shown in FIG. 9(B), after completing the insertion of the second terminal strip 21 into the second terminal strip accommodating portion 42 of each terminal accommodating portion 40 of the housing 31, by inserting the first terminal strip 11 into each first terminal strip accommodating portion 41, in each terminal accommodating portion 40, the connecting portion 15 of the first terminal strip 11 and the connecting portion 23 of the second terminal strip 21 are connected. Specifically, when the second terminal strip 21 is disposed in the second terminal strip accommodating portion 42, by inserting the first terminal strip 11 into the first terminal strip accommodating portion 41, the front side contact piece 16 of the first terminal strip 11 enters between the pair of upper side contact pieces 24 of the second terminal piece 21, and the front side contact piece 16 and the pair of upper side contact pieces 24 are in contact with each other.

Furthermore, the housing 65 is provided with an insertion recessed portion 71 into which the lower portion (the insertion portion 51 ) of the cable connector 1 is inserted. The insertion recess 71 is defined by the plate portions 66 to 70, and its upper side is opened. Also, a notch 72 is formed on the upper portion of the rear plate portion 68 .

Also, as shown in FIG. 11 , the board connector 61 includes 30 terminals 62 corresponding to the 30 terminals 5 included in the cable connector 1 . These terminals 62 are disposed in the insertion recess 71 . These terminals 62 are divided into two rows of a front row and a rear row, and 15 terminals 62 are arranged in a row in the left-right direction in each row. Furthermore, the 15 terminals 62 in the front row and the 15 terminals 62 in the rear row are arranged so as to correspond to each other in the front-rear direction.

Also, at the 30 terminals 62, the heights of the upper ends are respectively equal, and the positions of the contact portions 63 in the vertical direction are respectively equal.

Moreover, in the insertion recessed part 71, the partition plate 73 which partitions between the two terminals 62 adjacent to the front-back direction is provided. That is, the terminals 62 arranged in the front row and the terminals 62 arranged in the rear row are partitioned by the partition plate 73 . As shown in FIG. 10 , the partition plate 73 is elongated toward the up-down direction and the left-right direction, and the lower end of the partition plate 73 is supported by the lower plate portion 66 . Also, as shown in FIG. 11 , the left end 73A of the partition plate 73 is separated from the left plate portion 69 , and the right end 73B of the partition plate 73 is separated from the right plate portion 70 .

Also, as shown in FIG. 12 , each terminal 62 is separated from any one of the partition plate 73 , the front plate portion 67 , the rear plate portion 68 , the left plate portion 69 and the right plate portion 70 . Also, the front ends of the terminals 62 are located lower than the upper edges of the partition plate 73 , the front plate portion 67 , the rear plate portion 68 , the left plate portion 69 and the right plate portion 70 . Moreover, in the bottom surface of the insertion recessed part 71, the front part 71A is higher than the rear part 71B.

Also, as shown in FIG. 10 , a locking piece insertion portion 75 and a locking hole portion 76 are provided at the central portion in the left-right direction of the front plate portion 67 . Further, concave key portions 77 are respectively provided on the left and right portions of the front plate portion 67 .

As shown in FIG. 1, when the cable connector 1 is connected to the substrate connector 61, the insertion portion 51 of the cable connector 1 is inserted into the insertion recess 71 from above the substrate connector 61 while the convex key portion 58 and the concave key portion 77 are aligned with each other. When the insertion portion 51 enters the insertion recess 71 , the partition plate 73 provided in the insertion recess 71 enters the groove 54 provided at the insertion portion 51 of the housing 31 of the cable connector 1 . Also, when the insertion portion 51 enters the insertion recess 71, the lower portion of the front wall portion 34 of the cable connector 1 enters between the front plate portion 67 and the partition plate 73 of the substrate connector 61, the lower portion of the rear wall portion 35 of the cable connector 1 enters between the rear plate portion 68 of the substrate connector 61 and the partition plate 73, and the lower portion of the left wall portion 36 of the cable connector 1 enters between the left plate portion 69 of the substrate connector 61 and the partition plate. Between the left end 73A of 73 , the lower part of the right wall portion 37 of the cable connector 1 enters between the right plate portion 70 of the substrate connector 61 and the right end 73B of the partition plate 73 .

Also, when the insertion portion 51 enters the insertion recess 71, the contact portion 63 of each terminal 62 of the substrate connector 61 enters the second terminal piece receiving portion 42 through the terminal insertion hole 47 of the housing 31 of the cable connector 1, and contacts the contact portion 26 of the terminal 5 of the cable connector 1. Specifically, the contact portion 63 enters between the pair of lower contact pieces 27 , and the contact portion 63 and the pair of lower contact pieces 27 are in contact with each other.

Moreover, when the insertion portion 51 enters the insertion recess 71, the locking piece 56 enters into the locking piece insertion portion 75, and the locking protrusion 57 enters into the locking hole 76 and is locked.

As described above, in the cable connector 1 according to the embodiment of the present invention, the terminals 5 that are L-shaped when viewed from the side are formed by the first terminal piece 11 and the second terminal piece 21 that can be separated from each other, and the wall parts 32 to 37 and 43 to 45 of the housing 31 are respectively inseparably combined and integrated. Assuming that the portions extending in the front-rear direction and the portions extending in the up-down direction are inseparable from each of the L-shaped terminals 5 viewed from the side, it is impossible to assemble the terminals 5 into the case 31 in which the wall portions 32 to 37 and 43 to 45 are inseparably combined and integrated. However, in the cable connector 1 according to the embodiment of the present invention, among the terminals 5 that are L-shaped when viewed from the side, the portions elongated in the front-rear direction and the portions elongated in the up-down direction are respectively formed by the first terminal piece 11 and the second terminal piece 21 that can be separated from each other. Therefore, when assembling each terminal 5 into the case 31, by separating the first terminal piece 11 and the second terminal piece 21 of each terminal 5 from each other, it is possible to assemble each terminal 5 which is L-shaped when viewed from the side direction into the case 31.

In this way, by forming the L-shaped terminals 5 viewed from the side by the separable first terminal piece 11 and the second terminal piece 21, and forming the housing 31 into a structure in which the above-mentioned wall portions 32-37 and 43-45 are respectively inseparably combined and integrated, when the cable connector 1 is assembled, the process of assembling parts constituting the housing can be eliminated. That is, in the prior art cable connector having L-shaped terminals, the housing system is provided with a structure divided into plural parts in order to incorporate the integrally formed L-shaped terminals into the housing. Therefore, when assembling the cable connector, it is necessary to carry out the process of assembling the parts constituting the case. According to the cable connector 1 according to the embodiment of the present invention, such a process of assembling the parts constituting the case can be eliminated.

In this way, when assembling the cable connector 1, by eliminating the process of assembling the parts constituting the housing 31, the number of assembly processes of the cable connector can be reduced, and the assembly work of the cable connector can be simplified. Therefore, the workability of assembling the cable connector can be improved. Specifically, the seller of the cable connector 1 sells the cable connector 1 with the second terminal piece 21 of each terminal 5 assembled in the case 31 of the cable connector 1 . A user who has purchased the cable connector 1 only needs to connect the cable 80 to each first terminal piece 11, and then assemble each first terminal piece 11 into the housing 31 to complete the assembly operation of the cable connector 1. That is, the assembly process of the second terminal piece 21 shown in FIG. 9(A) into the housing 31 is completed in advance, and when the cable connector 1 is actually used, the assembly process of the first terminal piece 11 shown in FIG.

Also, in the embodiment of the present invention, the shape of each terminal 5 of the cable connector 1 is L-shaped, and each terminal 62 of the substrate connector 61 protrudes upward, and is separated from any one of the partition plate 73, the front plate portion 67, the rear plate portion 68, the left plate portion 69, and the right plate portion 70. According to such a configuration, by increasing the length of the vertically elongated portion of each terminal 5 of the cable connector 1, that is, the length of the second terminal strip 21 in the vertical direction, and increasing the length of each terminal 62 of the board connector 61 in the vertical direction, it is possible to increase the effective fitting length between each terminal 5 of the cable connector 1 and each terminal 62 of the board connector 61. Thereby, durability against diagonal pulling can be improved.

In addition, according to the embodiment of the present invention, by increasing the length of the portion (second terminal strip 21) that extends vertically at each L-shaped terminal 5 of the cable connector 1, and increasing the length of each terminal 62 of the substrate connector 61 in the vertical direction, the mutual contact between each terminal 5 and each terminal 62 can be ensured, and the height dimension of the substrate connector 61 can also be increased as shown in FIG. 13 . 1 is connected to the substrate connector 61, the cable connector 1 can be largely separated from the surface of the substrate on which the substrate connector 61 is mounted. Thereby, the cable connector 1 and the board connector 61 of this embodiment can be easily applied to products requiring potting on a board. If it is explained in detail, for example, in a substrate mounted on a home appliance, in order to prevent water immersion or contamination of the electrical components, electronic components, and circuits on the mounting surface of the substrate, there may be cases where resin is injected into the mounting surface of the substrate to bury the electrical components, electronic components, and circuits in the resin. In the case of inserting the board, it is necessary to increase the height of the board connector to such an extent that the board connector mounted on the mounting surface of the board is not buried in the resin. In addition, it is necessary to separate the cable connector 1 from the mounting surface of the substrate so that the cable connector connected to the substrate connector does not come into contact with the resin injected onto the mounting surface of the substrate. According to this embodiment, as shown in FIG. 13 , the height dimension of the substrate connector 61 can be increased, and the distance D between the cable connector 1 connected to the substrate connector 61 and the mounting surface 85A of the substrate 85 can be sufficiently increased with respect to the thickness E of the resin 86 injected onto the mounting surface 85A of the substrate 85. Therefore, it is possible to easily apply the cable connector 1 and the board connector 61 to a product that needs to be embedded in a board.

Also, in the embodiment of the present invention, in the substrate connector 61, the positions of the contact portions 63 of the 30 terminals in the vertical direction are respectively equal. On the other hand, at the insertion portion 51 of the cable connector 1, the positions of the contact portions 26 of the 15 second terminal strips 21 arranged on the front side are higher than the positions of the contact portions 26 of the 15 second terminal strips 21 arranged on the rear side. With this configuration, when the insertion portion 51 of the cable connector 1 is inserted into the insertion recess 71 of the board connector 61 , first, the contact portions 26 of the 15 second terminal pieces 21 arranged on the rear side at the insertion portion 51 of the cable connector 1 come into contact with the contact portions 63 of the 15 terminals 62 arranged on the rear side in the insertion recess 71 of the board connector 61 , and then, The contact portions 26 of the 15 second terminal strips 21 disposed on the aforementioned side at the insertion portion 51 of 1 are in contact with the contact portions 63 of the 15 terminals 62 disposed at the front side in the insertion recess 71 of the substrate connector 61. Thereby, for example, it is possible to connect the plurality of cables 80 and the circuits provided on the substrate in an appropriate order with a time difference, as in "after connecting the ground wires of the 30 cables 80 to the ground wires of the circuits provided on the substrate, and then connecting the signal wires of the 30 cables 80 to the signal lines of the circuits provided on the substrate". Therefore, when the cable connector 1 and the board connector 61 are connected, for example, electrical problems such as an abnormal current flowing in a circuit provided on the board can be prevented from occurring.

Also, in the embodiment of the present invention, in the insertion recess 71 of the substrate connector 61, a partition plate 73 for partitioning between the 15 terminals 62 arranged in the front row and the 15 terminals 62 arranged in the rear row is provided. Also, the front end of each terminal 62 of the board connector 61 is located below the upper edge of each of the partition plate 73 , the front plate portion 67 , the rear plate portion 68 , the left plate portion 69 , and the right plate portion 70 . Further, at the housing 31 of the cable connector 1, a groove 54 is provided at the second partition wall portion 44 provided between the 15 second terminal strip accommodating portions 42 disposed on the front side and the 15 second terminal strip accommodating portions 42 disposed on the rear side. Moreover, the left end 54A and the right end 54B of the groove part 54 are closed by the left wall part 36 and the right wall part 37, respectively. With this configuration, even when the position of the insertion portion 51 of the cable connector 1 is displaced from the position of the insertion recess 71 of the board connector 61 when the insertion portion 51 of the cable connector 1 is inserted into the insertion recess 71 of the board connector 61 , it is possible to prevent a part of the insertion portion 51 of the cable connector 1 from touching the terminal 62 of the board connector 61 from an oblique direction, and it is possible to prevent a part of the insertion portion 51 from touching the terminal 62 of the board connector 61 from an oblique direction. The shock generated by the contact causes the terminal 62 to bend. If it is explained in detail, each terminal 62 of the board connector 61 protrudes upward from the bottom surface of the insertion recess 71, and the front end of each terminal 62 is separated from any one of the partition plate 73, front plate portion 67, rear plate portion 68, left plate portion 69, and right plate portion 70. Therefore, if force is applied to the front end portion of the terminal 62 from an oblique direction, the terminal 62 may be bent. However, in this embodiment, if the insertion portion 51 of the cable connector 1 is not inserted into the insertion recess 71 of the board connector 61 in the correct position and in the correct direction, the insertion portion 51 of the cable connector 1 will not enter the insertion recess 71 of the board connector 61. For example, when the insertion portion 51 of the cable connector 1 is intended to be inserted into the insertion recess 71 obliquely toward the front, rear, left, or right relative to the insertion recess 71 of the board connector 61, the lower end of the left wall 36 or the lower end of the right wall 37 of the housing 31 of the cable connector 1 will be in contact with the upper end of the partition plate 73, the upper end of the front plate 67, the upper end of the rear plate 68, the upper end of the left plate 69, or Since the upper end of the right plate portion 70 touches, the insertion portion 51 of the cable connector 1 does not enter the insertion recess 71 of the board connector 61 . Therefore, it is possible to prevent a part of the insertion portion 51 of the cable connector 1 from touching the terminal 62 of the board connector 61 from an oblique direction, thereby preventing the terminal 62 from being bent. In addition, since the left end 73A and the right end 73B of the partition plate 73 are separated from the left plate portion 69 and the right plate portion 70 respectively, when the insertion portion 51 of the cable connector 1 is inserted into the insertion recess 71 of the board connector 61 in the correct direction at the correct position, the lower end portions of the left wall portion 36 and the lower end portion of the right wall portion 37 of the housing 31 of the cable connector 1 enter into the board connector 61 respectively. It is inserted into the “gap between the left end 73A of the partition plate 73 and the left plate portion 69 ” and “the gap between the right end 73B of the partition plate 73 and the right plate portion 70 ” in the concave portion 71 . As a result, the insertion portion 51 of the cable connector 1 is correctly inserted into the insertion recess 71 of the board connector 61 .

Moreover, in the cable connector 1 according to the embodiment of the present invention, the first terminal strips 11 of all the terminals 5 included in the cable connector 1 have the same shape. In addition, the second terminal pieces 21 of all the terminals 5 included in the cable connector 1 have the same shape. Therefore, commonization of components can be achieved for the plurality of first terminal strips 11 , and commonization of components can be achieved for the plurality of second terminal strips 21 . Therefore, the manufacturing cost of the cable connector 1 can be reduced.

In addition, in the above-mentioned embodiment, although the cable connector 1 with "the number of the terminals 5 and the terminal accommodating parts 40 and the like is 30" and the substrate connector 61 with "the number of the terminals 62 is 30" are given as examples, in the cable connector of the present invention, the respective numbers of the terminals and the terminal accommodating parts are not limited, and in the substrate connector of the present invention, the number of terminals is not limited. Regarding the connector 1 for cables, the respective numbers of the terminals 5 and the terminal accommodating portions 40 may be set to one. Also, in the cable connector 1 of the above-mentioned embodiment, although the plurality of terminal areas are divided into two stages and arranged, the plurality of terminals may be arranged in one stage, or the plurality of terminal areas may be arranged in three or more stages. Similarly, in the board connector 61 , a plurality of terminals may be arranged in three or more rows.

In addition, in the cable connector of the present invention, the structure for connecting the first terminal piece and the second terminal piece is not limited to the structure described in the embodiment. In addition, in the present invention, the structure in which the second terminal piece of the cable connector contacts the terminal of the board connector is not limited to the structure described in the embodiment. In addition, in the case of the cable connector of the present invention, it is not absolutely necessary to inseparably combine and integrate all the wall parts.

In addition, the present invention can be appropriately modified within the range that does not violate the abstract or idea of the invention that can be read from the claims and the entire contents of the specification, and the cable connectors and board connectors accompanied by such changes are also included in the technical idea of the present invention.
