Abstract

PROBLEM TO BE SOLVED: To contract the mounting area on a substrate and dispense with an inserting and drawing space by converting the horizontal movement by a member integrated with a jack to the vertical movement of an actuator to regulate the intensity of the contact force. SOLUTION: When a slide cam 17 is moved little by little to the left, a projection 23 is also moved. When the projection 23 is moved to the left, an actuator 15 is gradually lifted up since a slot 19 is inclined. When the slide cam 17 is continuously moved to the left and the projection 23 is moved, the actuator 15 is located in the top part, and a contact 18 is laid in the state where it is nipped and closed by the actuator 15. At this time, the contact force of the contact 18 is in the highest state. Accordingly, the slide cam 17 is horizontally moved, and the horizontal movement of the slide cam 17 is converted to the vertical movement of the actuator 15 to regulate the intensity of the contact force of the contact 18 with a pin 13.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an LIF connector having an actuator for adjusting the strength of contact between a jack-side contact and a plug-side pin. In recent years, communication equipment, personal computers, workstations, large-scale computers, and the like have a tendency that the number of pins of a connector on a substrate increases with an increase in signal lines due to high integration of circuits on the substrate and multifunctionalization. It is in. Therefore, in the case of a connector in which a multi-pin jack and a plug are fitted, a considerably strong force is required for insertion and removal. In such a case, the contact can be opened and closed by moving the actuator up and down,
An LIF connector that can be inserted / extracted with a low insertion / extraction force even with multiple pins is used.

[0002]

2. Description of the Related Art FIG. 1 shows a structure of a conventional LIF connector (only a jack portion is shown in FIG. 1). Conventional L
The jack portion 101 of the IF connector is moved up and down, for example, by attaching a pin 106 for connecting a board to a bottom portion and further attaching a contact 105 for inserting a pin of a plug portion to an upper portion. , An actuator 103 that adjusts the strength of the contact force between the contact 105 and the pin on the plug side, and a jack cover 104 that is an insulator for preventing problems such as short circuits due to external contact.

[0003] FIG. 2 shows that the jack 101 of FIG.
FIG. FIG.
2A is a top view, FIG. 2B is a front view, and FIG. 2C is a side view. Usually, a pin 106 for connecting a board is attached to the jack portion 101, and is inserted into a through hole of the board and soldered as shown in the figure. In addition, the actuator has a slit 1 having a slope.
12 are formed and used to adjust the strength of the contact force between the contact 105 and the pin on the plug side.

FIG. 3 shows a state in which a tool for an LIF connector is further attached to the state shown in FIG. 3A shows a top view, and FIG. 3B shows a side view. As shown in the figure, the LIF connector tool includes an operating portion 121 and an engaging portion 12.
2 and a slide cam 123, and the jack 10
The slide cam 123 is disposed so as to sandwich the slide cam 123. At this time, the projection 124 provided on the side of the jack 101 on the side surface of the slide cam 123 is located at a predetermined initial position of the slit 112 of the actuator 103 (see the initial position in FIG. 4A). When the projection 124 is at the initial position, the operation unit 121 of the tool is, for example, as shown in FIG.
As shown in (b), the state is vertical.

FIG. 4 shows the principle of operation of the actuator 103 by the tool shown in FIG. The tool is, for example, FIG.
4B and FIG. 4A, the actuator 103 is located at the lowermost position, and the contacts 105 of the jack portion 101 are open. At this time, the contact 105 has the lowest contact force. In this state, when the operation section 121 is gradually tilted toward the jack section 101, the gears of the engagement section 122 are engaged with each other, and the slide cam 123 is gradually pulled toward the engagement section 122. At the same time, the projection 124 of the slide cam 123 gradually moves in the direction of the arrow, that is, in the horizontal direction, as shown in FIG. When the protrusion 124 gradually moves in the horizontal direction, the actuator 103 is gradually lifted upward because the slot 112 is inclined.

When the operation unit 121 is tilted down until it comes into contact with the substrate 111, the protrusion 124 moves to the position shown in FIG.
The actuator 103 is located at the top, and the jack 1
01 contacts 105 are closed. At this time, the contact 105 has the highest contact force. As described above, the conventional connector uses the tool for the LIF connector, so that the actuator 10
3 to adjust the strength of the contact force between the contact 105 on the jack part 101 side and the pin on the plug side (not shown). Note that the tool shown in FIG. 3 does not need to be always attached to the substrate 111, and may be attached only when, for example, inserting or removing a pin of the plug portion.

[0007]

However, conventionally, since a tool for inserting and removing a pin of a plug portion is mounted on a board together with a jack portion of a LIF connector, the mounting area of the connector increases as a result. There was a problem. In addition, even if the tool is attached only when inserting and removing the pins of the plug portion, a space necessary for insertion and removal must be secured, and as a result, there is a problem that the mounting area of the connector is not reduced.

An object of the present invention is to make it possible to adjust the strength of the contact force due to the vertical movement of the actuator by using a member integrated with a jack or a plug, to further reduce the mounting area on the substrate, and to require a space for insertion and removal. An object of the present invention is to provide an LIF connector that does not require a connection. Another object of the present invention is to provide an LIF connector which requires a small force to slide the member horizontally when adjusting the strength of the contact force due to the vertical movement of the actuator by a member integrated with the jack or plug. Is to do.

[0009]

Therefore, in order to solve the above-mentioned problems, a connector of the present invention performs a vertical movement inside a jack so that a contact on a jack side and a plug side can be moved. A connector having an actuator (corresponding to actuators 15 and 35 of the embodiments described later) for adjusting the strength of the contact force of
The strength of the contact force is adjusted by converting a horizontal motion by a member integrated with the jack (corresponding to slide cams 17, 17a, and 37 in an embodiment described later) into a vertical motion of the actuator. It is characterized by.

In the conventional LIF connector, the actuator 103 is moved up and down by using the above-described tool (see FIG. 3).
23 is converted into a vertical motion of the actuator 103, and a contact 105 on the jack 101 side is formed.
The strength of the contact force of the pin on the plug side is adjusted. On the other hand, in the present invention, a member integrated with the jack, that is,
By integrating the slide cam and jack in advance,
An LIF connector that does not require tools can be provided. In other words, the LIF connector of the present invention does not require the operation part 121 and the engagement part 122 of the conventionally used tool. As a result, it is possible to reduce the mounting area on the board and further reduce the mounting area on the board. No insertion / extraction space is required.

In the connector according to the first aspect,
The jack includes a slot having a slope formed on both side surfaces of the actuator (corresponding to slots 19 and 39 in an embodiment described later) and a protrusion formed on the member. A projection 23 of an embodiment described later,
(Corresponding to 40) is engaged, and the horizontal movement of the member is converted into a vertical movement of the actuator by sliding the member in the horizontal direction.

For example, in the LIF connector according to the second aspect, the actuator is moved up and down by directly sliding the slide cam as the member in the horizontal direction. Thereby, the strength of the contact force can be adjusted.
Further, in the connector according to claim 1 or 2, the member has a structure (corresponding to a jack 11a in an embodiment described later) interlocked inside a plurality of jacks, as described in claim 3. Sliding the member in the horizontal direction converts the horizontal movement of the member into vertical movements of a plurality of actuators.

For example, in the LIF connector according to the third aspect, when the slide cam as the member is directly slid in the horizontal direction, the actuators inside the plurality of jacks are moved up and down in conjunction with the operation. This makes it possible to simultaneously adjust the strength of the contact force between the plurality of jacks and the plug. The connector according to any one of claims 1 to 3 may be, for example, a protrusion for preventing the jack and the plug from being turned upside down to one of the fitting portions of the jack and the plug as described in claim 4. (Protrusions 22, which will be described later,
43, and the other side is provided with a groove for upside-down prevention (corresponding to grooves 21, 44 in the embodiments described later).

According to the LIF connector of the fourth aspect,
It is possible to prevent upside down when inserting the pin of the plug, and accordingly, it is possible to prevent damage or accident of the electronic component due to erroneous insertion. Further, in the connector according to any one of claims 1 to 4, the jack is, for example,
According to a fifth aspect of the present invention, the semiconductor device is attached to the substrate by inserting a pin formed on the substrate.

According to the LIF connector of claim 5,
Substrate connection without soldering becomes possible, and accordingly, attachment to the substrate and removal from the substrate are facilitated, leading to a reduction in the number of work steps. Further, in the connector according to any one of claims 1 to 4, the jack has, for example, a positioning portion for fitting into a groove formed on a substrate at a base portion, as described in claim 6. It is characterized by having a projection (corresponding to a projection 42 of an embodiment described later).

According to the LIF connector of claim 6,
Positioning at the time of attachment to the board becomes easy, and the board and the jack can be reliably connected. For example, in the case of a connector in which the lead of the jack is soldered to the board, accurate connection can be ensured without short-circuiting. Further, in the connector according to the present invention, the protrusions are arranged at a constant pitch, and the slots are arranged at a pitch gradually different from the protrusions. In the horizontal direction is gradually converted into vertical movement of the actuator at gradually different timings (the invention according to claims 7 and 14).

Here, in the case where the member performing the horizontal movement has a structure interlocked inside a plurality of jacks, that is, in the case where a plurality of plug / jack constituent units are provided, a protrusion between each plug / jack constituent unit is provided. It is not necessary that the pitch interval between the slot and the slot be the same. Further, instead of the above configuration, a configuration may be adopted in which the slots are provided at a fixed pitch and the projections are provided at a pitch gradually different from the slots.

Thus, since the horizontal movement of the member is converted into the vertical movement of the plurality of actuators at gradually different timings, a large force required in the case of converting at the same timing is used in the timing. It is distributed and can operate the member with a small force. Further, the connector according to the present invention is a connector having an actuator that adjusts the strength of the contact force between the jack-side contact and the plug-side pin by performing up and down movement inside the jack. The strength of the contact force is adjusted by converting the movement in the direction into a vertical movement of the actuator (claim 8).

Thus, since the horizontal movement is performed by the member integrated with the plug, it is possible to provide a LIF connector which does not require a tool, thereby reducing the mounting area on the board and further reducing the mounting area. The insertion and removal space on the substrate becomes unnecessary. In addition, the jack cover is lighter in weight and the material cost can be reduced as compared with the case where the above-mentioned member performing the horizontal movement is integrated with the above-described jack. Here, that the above-mentioned member is integrated with the plug does not mean that the connector is physically inseparable and cannot be relatively displaced. Sometimes referred to as a state of being incorporated into a plug so that it can be handled integrally with a plug which is a component.

The adjustment of the strength of the contact force has a structure in which projections formed on both side surfaces of the actuator of the jack engage with slots having an inclination formed in the member of the plug, By sliding the member in the horizontal direction, the horizontal movement of the member is converted to the vertical movement of the actuator (the invention according to claim 9), which can be suitably performed.

Here, since a projection is formed on both sides of the actuator of the jack instead of a slot having an inclination, a member (slide cam) performing a horizontal movement and the actuator are integrally assembled. Can be omitted, and the number of manufacturing steps can be reduced. Further, in the connector according to the present invention, the member has a structure in which the members are interlocked inside the plurality of jacks, and by sliding the member in the horizontal direction, the horizontal movement of the member is caused by the vertical movement of the actuator. (Invention according to claim 10).

Thus, the strength of the contact force between the plurality of jacks and the plug can be simultaneously adjusted. The connector according to the present invention is characterized in that a fixed board is provided on a side surface of the jack in the longitudinal direction (the invention according to claim 11). In this case, for example, a projection is formed on the side surface in the longitudinal direction of the jack, and a groove is formed in the fixed substrate. The fixed substrate is attached to the jack by engaging the projection with the groove.

Thus, another substrate can be joined to the end of the fixed substrate, and the substrates can be stacked.
Further, in the connector according to the present invention, the plug has a hole for positioning and fixing the substrate by engaging with a fastening member passing through the projecting hole of the substrate having the hole. (The invention according to claim 12). The hole of this plug can be formed, for example, in a protrusion that extends to both ends in the longitudinal direction of the surface attached to the substrate having the hole, and the plug is formed by a fastening member such as a pin or a screw. It is fixed to the substrate. Still further, the connector according to the present invention is characterized in that a projection for positioning and fixing the board by engaging with the hole of the board having the hole is provided at the base of the jack. (The invention according to claim 13).

This makes it possible to connect the board without soldering, thereby facilitating attachment to and removal from the board, and further reduces the number of work steps.

It is possible to provide a connector, reduce the mounting area on the substrate 94, and eliminate the need for a space for insertion and removal on the substrate 94, which is the same effect as that of the first to third embodiments. Can be obtained. Further, in the fourth embodiment, it is possible to obtain a specific effect that the weight of the jack cover 86 is reduced and the material cost can be reduced. Also,
The substrate 99 can be further stacked and provided via the fixed substrate 70 attached to the base 82.

FIG. 20 shows a side view of the connector of the fifth embodiment. The connector 200 of the fifth embodiment is provided with two sets of plug main bodies 202 and jacks 204 constituted by substantially the same components as those of the fourth embodiment (hereinafter, one set of these plugs will be referred to as plugs). And jacks.) In this case, although not shown, as in the fifth embodiment, the projection of each jack 204 is engaged with the slot of the slide cam 206 attached to the plug main body 202. The movement is performed by the horizontal movement of one slide cam mounting member to which the slide cam is mounted.

According to the fifth embodiment, the strength of the contact force between the plurality of jacks 204 and the plug body (plug) 202 can be simultaneously adjusted by one slide cam 206. FIG. 21 shows a partial front view of the connector of the sixth embodiment. The jack and plug of this connector 208 are basically constituted by substantially the same components as in the fifth embodiment shown in FIG. Therefore, the protrusions 212 of the actuator 210 of each of the two jacks are engaged with the slots 218 of the slide cam 216 of the plug body 214. The contacts inserted into the jack actuator 210 and the pins provided on the plug to engage with the pins are omitted in FIG.

Here, although not described in the fifth embodiment, for adjusting the strength of the contact force between the jack 204 and the plug 202, for example, the same configuration as in the fifth embodiment is adopted. The plurality of protrusions 90 and the slots 80 shown in the fourth embodiment are arranged at the same pitch. That is, the spacing between the projections 90 and the spacing between the slots 80 are the same in the structural units of the jacks 68 and the plugs 66, and also between the structural units of the jacks 68 and the plugs 66. On the other hand, the pitches L1 and L of the protrusions 212 of the connector 208 of the sixth embodiment are different.
2 and the pitches M1 and M2 of the slots 218 are arranged at a different pitch (L1 (L2) ≠ M1 (M2)). In this case, the pitches L1 and L2 of the projections 212 are one structural unit of jack and plug. At a certain interval (L1
= L2), the pitches M1 and M2 of the slots 218 are provided gradually larger on the right side in FIG. 21 (M1 <M2). In this case, the pitch relationship between the constituent units of each jack and plug is the same (L1 = L3, L2 = L4, M1 = M3, M
2 = M4).

The operation of the connector 208 of the sixth embodiment will be described below. FIG. 21A shows a state immediately before the contact and the pin are engaged, that is, a state in which the actuator 210 is at a position farthest from the plug main body 214. When the slide cam (in other words, the slide cam mounting member) 216 of the plug main body 214 is horizontally moved rightward in FIG. 21 from the state of FIG. 21A as shown in FIG. The actuator 210 moves downward within the slot 218 having the actuator 210. At this time, the pitches L1 and L2 of the projections 212 are constant, while the pitches M1 and
Since M2 is provided gradually larger on the right side, the timing at which the protrusion 212 enters the slot 218 in the right direction is later on the right side in the figure, and as a result, the protrusion 212 on the left side is inclined by the inclination of the slot 218. At the point when the slot 218 is located near the lower right in the figure after passing through the right
2 is on its way through the sloped portion of slot 218.
That is, when the left end portion reaches the bottom surface of the lower plug main body 214, the downward movement of the right end portion is delayed when the left end portion reaches the bottom surface of the plug main body 214, and the left end portion in FIG. In FIG. 21, this state is exaggerated.) In this state, while the engagement between the contact at the left end of the actuator 210 and the pin progresses and the contact force is strong, the engagement between the right portion contact and the pin is delayed and the contact force is weak. is there. Therefore, the force required for the operation of moving the slide cam 216 of the plug body 214 to the right is dispersed in a timely manner, so that the operation can be performed with a small force. When the slide cam 216 of the plug body 214 is further moved rightward as shown in FIG. 3C, the projection 212 at the right end portion passes through the inclined portion of the slot 218 and reaches the lower right of the slot 218. As a result, a state is reached in which the contact and the pin are engaged with a strong contact force as a whole.

In this case, as long as the constituent units of each jack and plug are configured to perform the same behavior as in the sixth embodiment, the relationship of the pitch between the constituent units of each jack and plug is set. Need not be the same (L1 ≠ L3, L2 ≠ L4, M1 ≠ M3, M2 ≠ M4). Although not shown, the arrangement of the protrusions and the slots of the sixth embodiment described above is similarly applicable to the connections shown in the first to fourth embodiments.
The same operation and effect as those of the embodiment can be obtained.
