This is an example in which the lead wires 12 are attached to the terminals of the printed circuit board 13 and the lead wires 12 by inserting the printed circuit board 13 between the contacts 101 facing each other as shown in Figure b. Electrical connection is made with a connected inspection machine (not shown).

しまう欠点がある。Although this example can be carried out with the simplest configuration, printer boards are generally inspected very frequently and have a large number of contacts, so the contacts 101 are subject to severe wear due to the sliding of the printed board 13, which has the disadvantage of requiring frequent replacement. In addition, when inserting and removing the printed circuit board 13, sliding scratches are created on the board itself, and furthermore, workability is poor because a large amount of force is required, which places a great burden on the operator, especially when working for a long time. There is a drawback that you end up having to put a lot of effort into it.

The insulator 11 is installed on the frame 16 so as to be able to slide along a guide groove 160, and is always urged in one direction by an elastic body 164 such as a spring. Also,
A pair of rotating bodies 140 that can rotate around the fulcrum 130 are installed on the insulator 11, and these rotating bodies 140 have two
It is adapted to engage with the inner side of the tip end portion 102 of the contact terminal 10 in the row. An insulator 1 is provided on the side of this rotating body 140.
A roller 141 is installed at a position where the distance from the contact terminal 10 is approximately the same as the tip 102 of the contact terminal 10.
The opening/closing mechanism 14 that opens and closes the
Configure with. That is, as the wedge-shaped cam 150 enters between the two rollers 141, the rotating body 140 rotates slightly so as to open the contact terminal 10. The wedge-shaped cam 150 has a drive rod 152 passing through the insulator 11.
The guide groove 1 of the frame 16 is connected to the cylinder 151 by

The drive mechanism 15 is configured together with the cylinder 151 and the drive rod 152. Note that the cylinder 151 is fixed to the frame 16. The printed circuit board 13 is slid in the direction of arrow C with its shoulder portion 131 aligned with the guide groove 162 of the frame body 16, and is held at a position where it abuts against the protrusion 163. At this time, by advancing the wedge-shaped cam 150 between the two rollers 141 in advance and holding the opening/closing mechanism 14 in an open state, the connector terminal portion 132 of the printed circuit board 13 comes into contact with the contact 101 when inserted. Never. Therefore, the sliding operation becomes easy, and the contact 101 can be easily inserted into the connector terminal portion 132.
There is no sliding scratch, and there is no wear on the contact 101. Next, after inserting the printed circuit board 13, the drive mechanism 1

32 surfaces. Therefore, even if an insulating film or the like is interposed between the contact 101 and the connector terminal portion 132, it can be peeled off by the sliding action of the contact 101, so that it is not connected to the circuit mounted on the printed circuit board 13 and the lead wire 12. Electrical connection with a tester (not shown) can be made in good condition. Here, the sliding distance of the contact 101 is equal to the distance that the lower end of the wedge-shaped cam 150 further descends after contacting the insulator 11, and this distance is the operating range of the 1 drive rod 152 within the cylinder 151, or By restricting the sliding range of the insulator 11, it is possible to reduce the sliding range and easily design the contact 101 so that there is almost no wear due to sliding even during long-term use. In addition, the drive mechanism 15
The driving sources may be provided on both sides of the row of contact terminals 10, but a rotating shaft or the like for transmitting power is provided parallel to the row of contact terminals 11, and each drive source at both ends is connected via a cam or the like. It is also possible to transmit rotational motion to the rod 152 as a linear motion, so that the driving sources for the rotating shaft, etc. are unified, or by rotating an arm-shaped rod to the rotating shaft, this rod can be manually operated. 1
It may also be driven.

By adopting the drive mechanism 15 that slides the contact terminals 10, no force is required when inserting and removing them, compared to the conventional method in which the printed circuit board 13 is manually inserted while pushing the contact terminals 10 apart. As a result, work efficiency is significantly improved, and wear due to contact 101 sliding can be almost eliminated, so the frequency of replacing the contact terminal 10 is extremely low, and maintenance costs can be reduced.
