On the meeting surfaces, spaces 31b and 32b for accommodating a plurality of pin contact assemblies, which will be described in detail later, are formed in the surfaces 1 and 32, respectively. An alignment hole 31 for individually inserting and holding each contact 10 made of a slender elastic conductor constituting a pin contact combined body is provided on the surface side opposite to the meeting surface side.
a and 32a are formed at predetermined intervals. These alignment holes 31a, 32a communicate with the spaces 31b, 32b. In the pin contact assembly, a central portion of each of the plurality of pin contacts 10 is held by a mold bridge 21 as shown in FIG. 9 or a plastic film 22 as shown in FIG. It was done. As a result, the pin contacts 10 are arranged in a matrix in a horizontal plane defined by the second direction X and the third direction Z.

The connection of the connection target 60 is performed as follows. First, the object 60 to be connected is connected to the upper and lower insulating
By disposing the positioning pins 31 c and 32 c in the alignment holes 61 formed in the connection object 60, both ends of the pin contact 10 in the longitudinal direction are inserted into the socket contacts 63 of the connection object 60. And inserted in a loose fit. Next, the upper and lower connection objects 60 are generally horizontally moved in the directions indicated by the white arrows in FIG. As a result, the pin contact 10 is pressed against the inner surface of the socket contact 63 at two different positions in the first direction Y and the radial direction with the elastic deformation of the central portion in the longitudinal direction.

Incidentally, in the ZIF connector having such a structure, as shown in FIG. 12, the relationship between the contact force (P, F) and the operating force (W) for movement is W = (S / L). )

However, in the ZIF connector having the above structure, each contact 10 is connected to the insulating housing 3 at the time of connection as shown in FIG.
It curves greatly from the surface of 1, 32 inward. In addition, the socket contact 63 and the insulating housings 31, 3
If there is an error between the two alignment holes 31a and 32a, an abnormal contact state occurs as described below. For example, FIG.
Ready to (a), the excessive force on the corner portion of the alignment holes 3 1 a and the socket contacts 63 is generated, causing deformation or damage to the contact 10 and the housing 31. In addition, the state shown in FIG. 13B is reached, and the same thing occurs because the contact point of the pin contact 10 becomes one point.

Alignment holes 31 of insulating housings 31, 32
Such a situation can be avoided to some extent by setting a and 32a to have a size with a margin for the diameter of the pin contact 10. However, pin contact 1
When the density of 0 increases, the entrance of the socket contact 63 of the connection object 60 cannot be chamfered greatly, and FIG.
As shown in (2), the tips of the pin contacts 10 may be irregular, and the fitting connection to the connection target 60 may not be possible.

[0008] The technical problem of the present invention is that, in view of the above-mentioned drawbacks of the prior art, an abnormal contact state of the elastic conductor with the contact object as shown in FIG. 13 does not occur, and FIG.
An object of the present invention is to provide a low-operation-force connector that does not cause a state in which connection to a connection target such as a mating connector cannot be made due to irregularities in the ends of the elastic conductors as shown in FIG.

The pin contacts 10 face both sides in the thickness direction.

As shown in FIG. 3, a recess is formed at the center of the pin contact 10 and at the end face in the width direction, and the recess has a projection 20 on the wall surface facing the recess.
The f is snapped in and prevented from falling off in the vertical direction. Then, the concave portion of the pin contact 10 becomes a rotation center at the time of elastic deformation at the time of fitting connection described later. As described above, the pin contact 10 can bend only in a direction approaching the inclined wall surface 25b of the through hole 25, and is prevented from rotating by the vertical wall surface 25a in the opposite direction. That is, the pin contact 10 can rotate only in the counterclockwise direction about the center.

Similarly, the alignment hole 41 of the alignment plate 4 is also formed so that the wall surface 41b in the curved direction due to the elastic deformation of the pin contact 10 is inclined so as to escape upward, and the wall surface 41a on the opposite side is vertically inclined. Are formed so as to extend.

The holding section 20 and the alignment member 4 are housed in the housing 3. The housing 3 has a box shape having an opening formed on the upper side in FIG. Housing 3

The pin contact 10 is set slightly larger than the diameter of the pin contact 10 and has a straight posture before the connector is fitted.
Can be inserted without applying force.

As shown in FIGS. 1 and 2, the holding portion 20 is provided with an extension portion 20a which is a support surface extension portion for extending the vertical wall surface 25a of the through hole 25. The alignment plate 4 is also provided with an extension 4a which is a hole wall extension for extending the inclined wall surface 41b defining the alignment hole 41. The extension portions 20a and 4a are opposed to each other with a distance therebetween to regulate the posture of the tip of the pin contact 10 before the fitting connection. In the state shown in FIG. 1, when a force is applied to the upper alignment plate 4 to the right and to the lower alignment plate 4 to the left, the pin contact 10 is sandwiched between the extension portions 20a and 4a. The lower end of the pin contact 10 can be easily inserted into the socket contact 63 of the housing 3.

In FIG. 1, a recess 3c is formed in the left side wall of the housing 3. A return spring 7 (see FIG. 4) is interposed between the concave portion 3c and the upper alignment plate 4, and urges the upper alignment plate 4 toward the other end as described later.

The side wall opposite to the side wall where the concave portion 3c is formed has a portion facing the side surface of the mating connector 5 when the mating connector 5 as a connection target is fitted. Is provided with a drive cam 8. The drive cam 8 is partially cut away so as to form a string slightly smaller than a semicircle.

Next, the assembly of this connector will be described. In FIG. 1, the holder 20 and the alignment plate 4 are lowered, and the lower end of the pin contact 10 is inserted into the socket contact 63 of the housing 3. Recess 3 of housing 3
The alignment plate 4 is urged toward the drive cam 8 by a return spring 7 between c and the upper alignment plate 4. In this state, the pin contact 10 maintains the upright state, and the center line of the pin contact 10 and the center line of the socket contact 63 of the mating connector or the like 5 match. The drive cam 8 is in a state where the arc portion is housed in the side wall of the housing 3.

Next, the connection with the mating connector 5 will be described. When the lower end of the pin contact 10 is inserted into the socket contact 63 of the housing 3, the mating connector 5 is formed on the alignment plate 4 from the position shown by the phantom line in FIG. 4 (the position shown in FIG. 1). Guide 45
Is lowered so as to be inserted into the guide hole 5a of the mating connector 5, and the upper ends of the pin contacts 10 aligned upright into the socket holes of the socket contacts 63 of the mating connector 5 are inserted.

The diameter of the socket hole of the socket contact 63 of the mating connector 5 is also set to be larger than the diameter of the pin contact 10.
And the center line of the socket contact 63 coincides with each other, so that there is no need to apply force to the insertion, and the insertion is performed smoothly. Thereafter, the driving cam 8 is rotated, and the side of the mating connector 5 is pressed against the urging force of the return spring 7 by the arc portion of the driving cam 8. Then, as shown in FIG. 4, the alignment plate 4 connected to the mating connector 5 by the pin contact 10 moves to the left. That is, since the lower alignment plate 4 is fixed to the space 3a of the housing 3, the upper alignment plate 4 and the lower alignment plate 4 are fixed.

According to the present invention described above, the tip of the elastic conductor is inserted into the object to be connected with an extremely small force, and the object to be connected, such as the mating connector, is relatively moved in the opposite direction with a small force. A strong connection between the elastic conductor and the object to be connected can be obtained only by moving the object in parallel.

Moreover, according to the present invention, the posture of the elastic conductor before fitting can be held upright by the supporting surface formed in the through hole of the holding portion, and the connection due to the irregularity of the tip of the elastic conductor can be maintained. No more obstacles. In addition, when the elastic conductor rotates in the opposite direction above and below the center portion when connected to a connection object such as a mating connector, the elastic conductor is free because the through hole is formed to allow the inclination. To secure the connection between the elastic conductor and the object to be connected.

Further, according to the present invention, since the hole wall of the alignment hole of the alignment plate, which is deformed to the fluctuated second posture, is formed so as to be inclined, the elastic conductor is connected to the object to be connected. The alignment holes do not interfere with the elastic conductor during connection with the object, and the elastic conductor does not make abnormal contact with the connection target.

Further, according to the present invention, the support surface has the support surface extension and the hole wall extension so as to extend the hole wall of the through hole of the holding portion, so that the elastic conductor can be formed before connection. The alignment in the first posture is ensured, and the irregularity is eliminated. In addition, the forcing to the second posture can be surely performed, and the irregularity of the elastic conductor can be eliminated.
