The back surface of is set so that when the female contact 1 is inserted into the long groove 12, a predetermined gap d is formed between the female contact 1 and the upper edge of the tip 4a of the upper arm 4. d regulates the amount of upward movement of the upper arm portion 4.

Reference numeral 19 denotes a boss projecting from the lower surface of the housing main body 8, and is fixed to the printed circuit board 20 by the boss 19, and the connecting arm 5 is soldered to a copper foil (not shown) on the printed circuit board 20.

Reference numeral 21 denotes an operation plate that can be attached to the upper surface of the housing body 8, and has a size that is approximately the same as the planar area of the housing body 8. The front end of the operation plate 21 is connected to the tip 4a of the upper arm portion 4 via a vertical wall 22. A locking portion 23 that abuts the lower edge of is bent rearward. Further, hooks 24 are formed on the left and right sides of the operation plate 21 and can be freely engaged with and detached from the locking holes 18 formed in the side surface 17 of the housing body 8.

[Effect]

First, when used as a connector for thick NON ZIF contacts, only the housing body 8 is used, as shown in FIG.

Then, like a general-purpose connector, when the NON ZIF type contact 25 is inserted through the opening 10 of the housing body 8, the NON ZIF type contact 2
5 is sandwiched between the upper and lower contact portions 6 and 7 of the female contactor 1 and electrically connected.

Next, when using the connector for a thin ZIF type contact, as shown in FIG. Operation board 2
The operation plate 21 is pushed in so as to be closed by the vertical wall 22 of the housing body 8, and the hook 24 of the operation plate 21 is engaged with the locking hole 18 formed in the side surface 17 of the housing body 8. As a result, the front part of the back surface of the operation plate 21 is in close contact with the flat surface 16a of the housing body 8, the rear part of the back surface is separated from the inclined surface 16b, and the locking part 23 of the operation plate 21 is attached to the tip of the upper arm 4. It touches the lower edge of 4. In this state, the upper and lower contact portions 6 and 7 of the female contact 1 are in contact with each other.

Therefore, as shown in FIG. 4, when the rear part of the operation plate 21 is pressed, the locking part 23 of the operation plate 21 moves upward using the boundary part 15 of the housing body 8 as a fulcrum, so that the locking part 23 The tip portion 4a of the upper arm portion 4 that engages with the portion 23 is lifted upward,
Since the upper and lower contact parts 6 and 7 are separated, when the ZIF type contact 26 is inserted between the contact parts 6 and 7 and the pressing force applied to the rear part of the operation plate 21 is released, the upper arm part 4 is released. Because it restores
The ZIF type contact 26 is sandwiched between the upper and lower contact portions 6 and 7 to be electrically connected.

In addition, when pulling out the ZIF type contact 26 from the above state, press the rear part of the operation plate 21 again and engage the locking part 23 with the tip part 4 of the upper arm part 4.
If you lift up a and separate the upper and lower contact parts 6 and 7, the ZIF type contact 26 will come out from between both contact parts 6 and 7.
can be easily extracted.

As described above, in the case of the ZIF type contact 26, it is possible to connect and disconnect the upper and lower contact portions 6 and 7 with zero insertion force and zero extraction force.

[Other Examples]

In the above embodiment, the obtuse boundary portion 15 is used as a fulcrum in order to swing the operation plate 21 on the upper surface of the housing body 8, but as shown in FIG.
A protrusion 27 of a predetermined height is formed along the boundary part 15 to serve as a fulcrum, and a recess formed on the back surface of the operation plate 21 is engaged with the protrusion 27 to swing the operation plate 21. It may be configured as follows.

In addition, in order to increase the amount of upward movement of the tip 4a of the upper arm 4, as shown in FIG. A groove portion 28 may be formed so that the tip portion 4a can go in and out. In this case, there is no need to provide a gap d between the back surface of the ceiling part 14 of the housing body 8 and the upper edge of the tip part 4a of the upper arm part 4 of the female contact 1, and the thickness of the housing body 8 increases accordingly. It has the advantage that it can be made thinner.

[Effect of idea]

As described above, the connector according to the present invention includes a housing main body that houses a female contact, and an upper arm of the female contact that is removably attached to the upper surface of the housing main body and is formed by folding the front end to the back side. and an operating plate having a locking part that comes into contact with the lower edge of the tip of the female contact, and the contact part of the female contactor is rotated by swinging the operating plate using the boundary part or the protruding part of the housing body as a fulcrum. Since the connector is configured to connect and disconnect, it can be easily and quickly changed into a connector for both ZIF type contacts and NON ZIF type contacts by attaching and detaching the operation plate to the housing body. I can do it.

In addition, when used as a connector for ZIF type contacts, the ZIF type contact can be quickly inserted and removed from the female contact with one touch by simply pushing and releasing the operation plate. In addition, since the shape of the housing body and the operation plate are simple, the shape of the mold is simple, and there are various effects such as cost reduction and development delivery time can be shortened.
