[Prior art]

 2. Description of the Related Art In recent years, flexible printed wiring boards and the like have been widely used for small and lightweight electric and electronic devices because of their advantages such as ease of assembly and reduction of installation space. Therefore, it is necessary to inspect these flexible printed wiring boards themselves and circuits formed by mounting electronic components on the wiring boards. This inspection is generally performed by circuit-connecting a plurality of conductor terminals arranged at the ends of the flexible printed wiring board to the terminals of the tester for inspection. Moreover, for quick inspection, circuit connection and disconnection must be easy.

In order to perform such an inspection, a clip type relay connector shown in FIGS. 4 and 5 has been used as an example of a relay connector for connecting a conductor terminal of a flexible printed wiring board and a tester. FIG. 4 is an exploded perspective view of an example of a conventional clip-type relay connector, and FIG. 5 is a vertical cross-sectional view of a main part in which the arm portion is in the separated position in FIG.

4 and 5, the flexible printed wiring board 10 has a constant thickness, and conductor terminals 14, 14 ... Are appropriately arranged on the surface of the end portion 12 thereof. The conductor terminals 14, 14 ... Are connected to the printed wiring circuit by conductors. In addition, an arm portion 18, which is also made of an insulating material, is swingably configured by a horizontal shaft 20 on a base 16 made of an insulating material, on which the end portion 12 of the flexible printed wiring board 10 can be placed, and the tip portion of the arm portion 18 is made to swing. The base 16 can be approached and separated. Then, at the approaching position to the tip end of the arm portion 18, the probe 22, so as to appropriately come into contact with the conductor terminals 14, 14 ... Of the flexible printed wiring board 10 placed at a predetermined position on the base 16. 22 ... Are arranged. The probes 22, 22 ... Are appropriately connected to a tester (not shown) via a connection board 24. Reference numerals 26 and 26 are coil springs that elastically bias the arm portion 18 toward the approaching position.

In such a configuration, the arm portion 18 is set to the separated position against the elasticity of the coil springs 26, 26, and the flexible printed wiring is provided in the large gap generated between the base 16 and the tip portion of the arm portion 18. When the end portion 12 of the substrate 10 is inserted and the regulation of the arm portion 18 is released, the elastic force of the coil springs 26, 26 causes the arm portion 18 to swing to the approaching position, and the conductor terminals 14, 14 ... 22 are brought into contact with each other, and the conductor terminals 14, 14 ... And the tester are circuit-connected.

[0006]

[Problems to be solved by the device]

 In the conventional clip-type relay connector shown in FIGS. 4 and 5, the probes 22, 22 are brought into contact with the conductor terminals 14, 14 ... Of the flexible printed wiring board 10 to be circuit-connected, The force for fixing the flexible printed wiring board 10 is weak due to the elasticity of the coil springs 26, 26 and the probes 22, 22 ... Therefore, when a force that presses the flexible printed wiring board 10 acts in this state, a force in the direction of pulling out the end portion 12 from the base 16 acts due to the flexibility, and its position There is a problem that the probes 22, 22 ... Are easily disengaged from the conductor terminals 14, 14 ...

Further, when the flexible printed wiring board 10 is inserted into the gap between the base 16 and the arm portion 18, if the end portion 12 is inserted at a position raised from the base 16, the end edge of the flexible printed wiring board 10 is inserted into the probe 22, There is a possibility that the probes 22, 22 ... may be bent by pressing the lateral side of 22 ... When the probes 22, 22 ... Are bent, the positions of contact with the conductor terminals 14, 14 ... Are displaced and proper circuit connection cannot be achieved.

The present invention has been made in order to improve the problems of such a conventional clip-type relay connector. It is difficult for the printed circuit board to be pulled out when the probe is in contact with the conductor terminal, and the printed circuit board is difficult to pull out. An object of the present invention is to provide a clip-type relay connector that does not cause the probe to bend when inserting the connector.

[0009]

[Means for Solving the Problems]

 In order to achieve such an object, the clip-type relay connector of the present invention is provided with an arm portion which can be connected to and separated from the base, and when the arm is at the separation position, the arm is printed between the base and the arm. Clip-type relay that inserts the end of the board and moves the arm to the approaching position so that the probe mounted on the arm comes into contact with the conductor terminal mounted on the surface of the end of the printed circuit board. In the connector, a recess is formed on the back surface of the end of the printed circuit board along the edge so that a step can be engaged with the base, and the end of the printed circuit board is inserted into the base. A gate is provided so as to cover a side of the arm of the arm at a separation position that allows the probe to be inserted in the printed board.

Further, an arm portion is provided to the base so that the arm portion can be freely approached and separated, and when the arm portion is at the separation position, the end portion of the printed circuit board is inserted between the base and the arm portion to bring the arm portion closer to each other. In the clip-type relay connector in which the probe disposed on the arm portion comes into contact with the conductor terminal disposed on the surface of the end portion of the printed circuit board when the position is set, the insertion direction is set on the back surface of the end portion of the printed circuit board. And forming a concave step portion that engages with the step of the step portion on the base, and further having a gap into which the end portion of the printed circuit board can be inserted in the base. At the same time, a gate may be arranged so as to shield the arm portion at the separation position from the probe insertion direction side of the printed circuit board.

[0011]

[Work]

 When the end of the printed circuit board is inserted and the probe is in contact with the conductor terminal, the step formed on the back surface of the end of the printed circuit board or the step provided on it will not be the same as the concave part formed on the base. Even if a force is applied to the printed circuit board in the direction of pulling out the end portion of the printed circuit board, the positional displacement does not easily occur. Moreover, since the gate is provided on the base so as to cover the arm in the separated position on the insertion side of the probe, when the printed circuit board is inserted, its edge contacts the probe and is bent. There is no fear.

Here, in the commercially available flexible printed wiring board 10, the end 12 is made thick in advance for the purpose of reinforcing the end 12, and the thick portion forms a step 30a along the edge on the back surface. There is something. In such a case, the recess 32 may be bored in the base 16 so that the step 30a can be engaged. Further, the base 16 is provided with positioning members 34, 34 on both sides for restricting a lateral position when the end 12 of the flexible printed wiring board 10 is inserted. The positioning members 34, 34 are provided with tapered guides 34a, 34a whose front ends are open on both sides. Further, the base 16 has a gap d into which the end 12 of the flexible printed wiring board 10 can be inserted along the base 16, and the probes 22, 22, ... On the other hand, the gate 36 is arranged so as to shield it on the insertion side. The gate 36 is provided with a tapered guide 36a having a widened gap at the tip. In addition, in the embodiment, the positioning members 34, 34 and the gate 36 are integrally formed.

Of the flexible printed wiring board 10. At the same time, the step portion 30 on the back surface of the end portion 12 is fitted into the concave portion 32 of the base 16. In such a state, since the step 30a on the back surface of the flexible printed wiring board 10 engages with the edge of the concave portion 32, some force is applied to the flexible printed wiring board 10 and the end portion 12 is applied. Even if the force to pull out is applied, the position does not shift.

In the description of the above embodiments, the flexible printed wiring board is described as an example, but the present invention is not limited to this, and even a non-flexible printed board may be used. I wish I had it.
