The present invention relates to a ZIF (ZERO I)
NSERTION FORCE).

[0002]

2. Description of the Related Art A conventional ZIF connector is shown in FIGS. In FIG. 7, a plurality of thin and long elastic pin contacts 81 fixed to a base 82 are inserted into a plurality of socket contacts 84 fixed to a housing 83. In this case, since the hole diameter of the socket contact 84 is larger than the pin diameter of the pin contact 81,
The force required for insertion is zero. Next, as shown in FIG. 8, when the housing 83 is moved to the left in a direction perpendicular to the axis of the pin contact 81, the pin contact 81 is inclined, and the tip of the pin contact 81 is located at two places on the inner wall of the hole of the socket contact 84. Contact.

At this time, the forces received by the socket contacts 84 from the pin contacts 81 at the two inner walls are P and F.
Then, in this structure, one of the socket contacts 84
Since the forces received from the pin contact 81 are P and F in opposite directions, the force for supporting the socket contact 84 against it must be (P−F) = W. Therefore, the force for maintaining the whole in the state of FIG.
Then, n × (P−F) is obtained. Simply put, since W is much smaller than P, n pin contacts 8
The force required for contact between the socket contact 1 and the socket contact 84 is n
XW, this structure can move with less force.

In the prior art, as shown in FIG. 9, when the pin contact 81 is abnormally deformed, there is a problem that the pin contact 81 cannot be inserted into the socket contact 84. As a measure to improve this obstacle, as shown in FIG. 10, the vicinity of the tip of the pin contact 81 is inserted into a locator 85 having holes 86 arranged in the same manner as the pin contact 81, and the tip of the pin contact 81 and the socket contact 84 are not aligned. Is known to correct
As shown in FIG.
Therefore, the hole 86 of the locator 85 must be considerably widened. Then, the means for correcting the irregularity does not sufficiently improve the obstacle.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention solves the above-mentioned problem of the prior art, and occurs when a plurality of elastic pin contacts are connected to a mating socket contact due to irregularities in the tips of the elastic pin contacts. It is intended to prevent trouble.

[0006]

According to the present invention, in order to solve the above-mentioned problems, a plurality of elastic pin contacts are arranged and fixed on a base, and a lower lid and an upper lid of an insulating locator and a plurality of sockets are provided. A housing provided with a contact is disposed on the base so as to be movable in an arrangement direction of the pin contacts, and a hole larger than the pin contact is formed in the lower lid and the upper lid in the same arrangement as the pin contacts. By moving the other with respect to one of the lower lid and the upper lid in a direction perpendicular to the deformation direction of the pin contact, the tip of the pin contact is aligned so that it can be inserted into the socket contact, and the housing To the base side, and move the lower and upper lids and the housing of the locator in a direction perpendicular to the axis of the pin contact. By moving the pin contacts without contacting the lower lid and the upper lid of said locator,
As means, a ZIF connector in which a contact force is generated between the pin contact and the socket contact in a direction perpendicular to the axis of the pin contact.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS.

In FIG. 1A, a plurality of thin, long, linear elastic pin contacts 61 are provided on a base 62.
Are arranged and fixed at right angles to each other, and the holes 64 of the lower lid 63 and the holes 66 of the upper lid 65 are inserted through the insulating locators of the same arrangement. Here, since the pin contacts 61 are abnormally deformed, the respective tips cannot be inserted into the socket contacts 71 fixed to the housing 70 as they are. Therefore, in FIG.
2 is pressed against the compression coil spring 73 shown in FIG. 6 in the direction of the arrow, as shown in FIG. 1 (B), the upper lid 65 is moved in a direction perpendicular to the plane of the paper, and the upper lid in which the pin contact 61 is inserted is inserted. By changing the location of the hole 66 of the 65 from a wide portion to a narrow portion as described later, the tip of the pin contact 61 is corrected so as to be directed to the center of the socket contact 71.

The operation of correcting the pin contact 61 will be described in detail. The change in the positional relationship between the pin contact 61, the hole 64 of the lower cover 63, and the hole 66 of the upper cover 65 is shown in FIG.
(B) and (C). That is, FIG.
(A) shows the state before the straightening operation (the state of FIG. 1 (A)), and the pin contact 61 is located in the hole 64 (broken line). Are not located at the center in the left-right direction within the inverted convex hole 66 (solid line) formed by Then, when the upper lid 65 is moved upward in parallel with the paper surface of FIG.
7 to the groove 69, that is, the center position in the left-right direction via the curved portion 68, and reaches the state (FIG. 1B) in the middle of the correction operation shown in FIG. 2B. Subsequently, after the pin contact 61 is inserted into the socket contact 71, the upper cover 65 is moved downward in parallel with the paper surface of FIG.
Reaches the state after the correction operation shown in FIG. 2C (the state of FIG. 3A). At this time, the pin contact 61 does not move.

In FIG. 5, when the lever 79 fixed to the cam 78 is rotated by 90 ° to the right, the peripheral surface of the cam 78 moves the housing 70 and the lower lid 63 and the upper lid 65 of the locator to the left on the pedestal 76. . At this time, the housing 7
The protrusions 75 fixed to both sides of the base 0 move leftward from the right-angled portions of the L-shaped grooves 74 provided on the base 62 for positioning. When the lever 79 is rotated counterclockwise by 90 ° to return to the position shown in FIG. 5, the housing 70 and the lower lid 63 and the upper lid 65 of the locator are restored by the compression coil spring 77.

The housing 70 and the lower lid 63 of the locator
When the upper lid 65 moves to the left, the pin contact 61 does not contact the lower lid 63 and the upper lid 65 of the locator, but at two points with the socket contact 71 of the housing 70 as shown in FIG. The contacts make contact and the connector is connected.

[0012]

According to the present invention, since the present invention is configured as described above, it is possible to prevent the tips of the plurality of pin contacts from being irregular. Further, according to the present invention, a plurality of pin contacts having elasticity can be reliably inserted into the plurality of socket contacts, respectively, and the effect of successfully connecting the connector can be obtained.
