Further, the positioning recess 214 has a downwardly curved shape and is arranged so that a rotation shaft portion 31 of the rotation lever 30 described later is positioned, and is accommodated together with the positioning claw portion 213 and the locking projection 214. The position of each plate-like contact 20 in the part 11 is determined.

The end of the second contact portion 22 closer to the insertion port 12 has a downward convex facing the first contact portion 211 and toward the first contact portion 211 (that is, toward the lower side in FIG. 2). A second contact portion 221 as an example of a movable contact portion protruding in a triangular shape is provided. The second contact portion 221 is also disposed in the recess 111. In addition, a pressed portion 222 that is pressed by a pressing portion 32 of the rotation lever 30 described later is provided at an end portion of the second contact portion 22 far from the insertion port 12.

The connection portion 23 extends in a direction intersecting the first contact portion 21 and the second contact portion 22, and between the first contact portion 211 and the base portion 212, more specifically, the connection portion 23 includes the recess 111 and a rotation lever. 30. Thereby, the second contact portion 22 of each plate-like contact 20 has the second contact portion 221 downward in FIG. 2 with the connection portion 23 as a fulcrum when the pressed portion 222 is pressed upward in FIG. In order to bend, they can be elastically deformed independently of each other.

As shown in FIG. 1, the rotation lever 30 has a substantially rectangular box shape, extends in the longitudinal direction of the housing 10 so as to cross all the accommodating portions 11, and is rotatably supported by the housing 10. ing. As shown in FIG. 2, the rotation lever 30 includes a rotation shaft portion 31 and a pressing portion 32 connected to the rotation shaft portion 31.

Further, as shown in FIG. 1, the rotating lever 30 has a trapezoidal protrusion 33 in the middle in the longitudinal direction of the housing 10. By operating this protrusion 33, the rotation lever 30 is rotated. The rotation lever 30 has a direction in which the protruding portion 33 is substantially orthogonal to the extending direction of the accommodating portion 11 (that is, the left-right direction in FIG. 2) (that is, in the plan view as viewed along the longitudinal direction of the housing 10). 2 can be rotated between an open position (upward in FIG. 2) and a closed position (see FIGS. 6 and 7) in which the protruding portion 33 extends in a direction substantially parallel to the extending direction of the accommodating portion 11. It has become.

As shown in FIG. 2, the rotating shaft portion 31 has a circular shape in a plan view seen along the longitudinal direction of the housing 10, and is provided at an end portion on the opposite side of the protruding portion 33. The rotation shaft portion 31 is disposed between the connection portion 23 and the base portion 212 of the first contact portion 21 and between the first contact portion 21 and the second contact portion 22, and extends along the longitudinal direction of the housing 10. The housing 10 extends from the housing portion 11 at one end to the housing portion 11 at the other end. The axis of the rotation shaft portion 31 is the rotation axis of the rotation lever 30.

The pressing portion 32 protrudes from the rotating shaft portion 31 in a direction intersecting with the protruding direction of the protruding portion 33 (that is, upward in FIG. 2) (that is, leftward in FIG. 2). The pressing portion 32 is a direction in which the pressed portion 222 of the second contact portion 22 of each plate-like contact 20 moves away from the first contact portion 21 as the rotation lever 30 rotates (that is, upward in FIG. 2). Can be pressed. That is, in a plan view as viewed from the longitudinal direction of the housing 10, the total length of the diameter of the rotation shaft portion 31 and the length of the pressing portion 32 in the protruding direction is the first contact portion 21 and the second contact portion 22. It is larger than the length between the pressed part 222.

Next, the operation of the electrical connector 100 when the flat conductor 200 is connected will be described with reference to FIGS. 4 and 5 show the electrical connector 100 when the rotating lever 30 is in the open position, and FIGS. 6 and 7 show the electrical connector 100 when the rotating lever 30 is in the closed position. Yes.

First, as shown in FIG. 4, the flat conductor 200 is inserted from the insertion opening 12 into the recess 111 and between the first contact portion 211 and the second contact portion 221 of each plate-like contact 20.

At this time, as shown in FIG. 5, the rotating lever 30 has a direction in which the protruding portion 33 is substantially orthogonal to the extending direction of the housing portion 11 (that is, in a plan view seen along the longitudinal direction of the housing 10 (that is, , In an open position extending upward (FIG. 5). In this open position, the pressing portion 32 extends from the rotating shaft portion 31 in the extending direction of the accommodating portion 11 (that is, leftward in FIG. 5), and the pressed portion 222 of each plate-like contact 20 is connected to the rotating lever 30. It is in a natural state that is not pressed by the pressing portion 32. Each of the first contact portion 211 and the second contact portion 221 is in contact with the flat conductor 200 in a state where the flat conductor 200 can be inserted into and removed from the recess 111.

After the flat conductor 200 is inserted into the recess 111 and between the first contact portion 211 and the second contact portion 221 of each plate-like contact 20, until the front end surface of the flat conductor 200 contacts the bottom surface 112 of the recess 111. The protrusion 33 is operated to rotate the turning lever 30 in the direction away from the insertion port 12 from the open position shown in FIG. 4 to the closed position shown in FIG.

At this time, as shown in FIG. 7, the pressing portion 32 is a direction substantially orthogonal to the extending direction of the accommodating portion 11 from the position extending in the extending direction of the accommodating portion 11 as the rotating lever 30 rotates. It rotates to the position extended in (namely, upward of FIG. 7), and presses the to-be-pressed part 222 of each plate-shaped contact 20 in the direction away from the 1st contact part 21 (namely, upward of FIG. 7). When the pressed part 222 is pressed in the direction away from the first contact part 21, the pressed part 222 of each plate-like contact 20 is pushed up in the direction away from the first contact part 21 and elastically deformed, thereby connecting With the portion 23 as a fulcrum, the second contact portion 221 bends so as to be pushed down in a direction approaching the first contact portion 21. As a result, the second contact portion 221 elastically presses the flat conductor 200, and the contact pressure of the first contact portion 211 and the second contact portion 221 with respect to the flat conductor 200 increases.

On the other hand, when the rotating lever 30 is rotated from the closed position to the open position in a direction approaching the insertion port 12, the pressing portion 32 extends in a direction substantially orthogonal to the extending direction of the accommodating portion 11. It rotates to the position extended in the extending direction of the accommodating part 11 from the position. Accordingly, the pressed portion 222 of each plate-like contact 20 that has been pressed in the direction away from the first contact portion 21 by the pressing portion 32 returns to the natural state shown in FIG. 5, and the flat shape by the second contact portion 221. The pressure on the conductor 200 is released, and the flat conductor 200 is brought into a state where it can be inserted into and removed from the recess 111.

In the electrical connector 100, the housing 10 having the accommodating portion 11 provided with the insertion port 12 into which the flat conductor 200 can be inserted, and the two accommodated in the one accommodating portion 11 in a stacked state in the plate thickness direction. Two plate-like contacts 20 are provided. Each of the second contact portions 221 of the two plate contacts 20 is configured to be able to be pressed independently against the flat conductor 200 by elastic deformation. Thereby, even if a foreign object adheres to one second contact portion 221, the flat conductor 200 can be pressed by the other second contact portion 221, and the contact reliability between the electrical connector 100 and the flat conductor 200 can be improved. Decline can be prevented.

In other words, two plate contacts 20 that are conventionally one are accommodated in one accommodating portion 11 as a set, and the number of contact portions that contact one connection terminal of the flat conductor 200 is doubled. Thus, stable contact with the flat conductor 200 can be maintained even when vibration and impact are applied. It is functionally fatal to cause chattering due to separation of the contact portion and the flat conductor 200 due to resonance or simple reaction caused by application of vibration and impact. If the number of contact portions is doubled, the possibility of chattering can be reduced by at least half. In addition, since the four contact portions can be arranged on one line in the vertical direction, the degree of freedom in designing the plate contact 20 can be increased.

As described above, the electrical connector 100 can realize a structure that could not be realized by a conventional electrical connector, and can realize an electrical connector having strong vibration resistance required for electronic parts for automobiles in recent years. In addition, since two contacts are arranged in one accommodating part, the conductor cross-sectional area increases as compared with the case where one contact is arranged in one accommodating part. For this reason, it becomes possible to flow more electric current than the conventional electrical connector with which one contact is arrange | positioned in one accommodating part.

As shown in FIGS. 8 and 9, a gap forming member 41 that forms a gap 40 between the plate contacts 20 may be provided on at least one of the opposing surfaces of the two plate contacts 20. Thus, by providing the gap forming member 41 and forming the gap 40 between the two plate contacts 20, each plate contact 20 can be elastically deformed easily and more reliably independently.

Further, by providing a plurality of gap forming members 41 in the middle of the first contact part 211 and the base 212 of the first contact part 21, the gap 40 can be more reliably maintained. Specifically, as shown in FIG. 9, two regions to which the connection portions 23 of the first contact portion 21 and the second contact portion 22 are connected, and a base portion 212 and a positioning claw portion 213 of the first contact portion 21, By providing it in any two of the three regions, the gap 40 can be more reliably maintained.

In addition, when the gap 40 is provided between the two plate contacts 20, if the base 212 is connected to the substrate using solder, the gap 40 is penetrated by the solder or the flux due to a capillary phenomenon, so that the two plates There is a risk of sticking the contact. In order to prevent the sticking of the plate-like contact 20 due to such solder, for example, as shown in FIG. 10, the first contact portion 211 of the first contact portion 21 of the two plate-like contacts 20 and the middle of the base portion 212 may be used. A plating portion 42 that can prevent molten solder from penetrating into the gap 40 is provided on each facing surface of the portion close to the base portion 212, that is, the portion between the connection portion 23 of the first contact portion 21 and the positioning claw portion 213. Just do it.

The plating portion 42 is made of, for example, a nickel-rich nickel gold alloy, and the nickel gold alloy functions as a nickel barrier (solder wetting prohibition zone). For this reason, the penetration of the molten solder into the gap 40 is prevented by providing the plated portion 42 on the opposing surface of each plate-like contact 20 that forms the gap 40.

Further, the two plate contacts 20 are not limited to the same shape as a whole, and as shown in FIG. 11, at least the shapes of the first contact portion 211 and the second contact portion 221 are different. Good. Thus, since the shape of the laminated plate-like contacts 20 can be arbitrarily changed, the resonance point of the two plate-like contacts 20 can be arbitrarily set. Thereby, the electrical connector 100 resistant to vibration can be realized.

Further, in the electrical connector 100, a pair of the first contact portion 211 and the second contact portion 221 that are opposed to each other for each plate-like contact 20 is provided, but this is not a limitation. For example, each plate-like contact 20 may be provided with a plurality of sets of contact portions facing each other. Further, as shown in FIG. 12, a plate-like contact 120 having only the first contact portion 211 can be used.

The insertion port 12 is not limited to being provided on one of the side surfaces extending in the longitudinal direction of the housing 10. For example, as shown in FIG. 13, the insertion port 12 may be provided on the upper surface of the housing 10. In this case, for example, as shown in FIG. 14, the housing 10 is provided with a plurality of accommodating portions 11 that are open at both ends in the vertical direction, and a plurality of plate contacts 20 are stacked in the thickness direction in one accommodating portion 11. Contained in state. The accommodating portion 11 is provided with an insertion portion 12 and a recess 111 at an end portion on the right side in the short direction (that is, the right side in FIG. 14), and a rotating lever at an end portion on the left side in the short direction (ie, on the left side in FIG. 14). 30 is arranged. The plate-like contact 20 includes a lateral member 24 extending along the bottom surface of the housing 10 (that is, the lower surface in FIG. 14) in the short direction of the housing 10 (that is, the left-right direction in FIG. 14), A first contact portion 21 extending upward from the right end portion of the lateral member 24, a longitudinal member 25 extending upward from the left end portion of the lateral member 24, and the first contact portion 21 from the longitudinal member 25. And a second contact portion 22 having a base portion 223 extending obliquely upward and an arm portion 224 extending upward along the first contact portion 21 from the base portion 223. A positioning recess 214 is provided at the tip of the longitudinal member 25. Further, a pressed portion 222 is provided on the arm portion 224 of the second contact portion 21, and the second contact portion 221 faces rightward with the bent portion 225 between the base portion 223 and the arm portion 224 as a fulcrum (that is, It is elastically deformable so as to bend in a direction approaching the first contact portion 211.

In the electrical connector 100, a so-called ZIF backlock electrical connector has been described. However, the present invention is not limited to this, and can be applied to electrical connectors of other structures (such as NON-ZIF system). .

The number of plate contacts 20 to be stacked is not limited to two, and may be three or more.
