That is, the contact terminals 10 having electrical conductivity and elasticity (for example, phosphor bronze), which are arranged and fixed in two rows facing each other through the insulator 11 , are connected to each other by the opening/closing mechanism 14 at the tip ends 102 of the contact terminals 10 . The contact points 101 are opened in the direction of , and the distance between the opposing contacts 101 is wider than the thickness of the printed circuit board. Third
FIG.
Since the can be inserted without contacting the contact 101, no great force is required, and the contact 10 can be inserted freely into the terminal section of the printed circuit board 13.

を挟む。First, the contact terminals 10 are arranged facing each other in two rows on an insulator 11 with their intermediate parts fixed so that the contacts 101 face each other at a constant interval, and the lead wires 12 are connected to the terminal parts 103 of the contact terminals 10. ing. 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
61, opens and closes the opening/closing mechanism 14 when going up, and pushes down the insulator 11 when going down.
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
5 to separate the wedge-shaped cam 150 from between the rollers 141, the opening/closing mechanism 14 closes due to the elasticity of the contact terminals 10, and each of the opposing contacts 101 connects to the connector terminal section 132.

1, the insulator 11 descends along the guide groove 160, and along with this, the contact 101 also touches the connector terminal portion 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.
