Abstract

PROBLEM TO BE SOLVED: To provide a clip type repeating connector which can connect and separate a circuit speedily and excellently irrelevantly to the style of an inspection object. SOLUTION: When an upper clip 12 is operated downward, the tip part of the upper clip 12 swings up on a shaft 13. Consequently, a slide block 18 linked with the tip part of the upper clip 12 moves up in parallel along a slide shaft 17. Namely, an upper block 16 mounted on the slide shaft moves up and down in parallel by the clip operation. A probe 19 mounted on the upper block, therefore, move always at the vertical attitude to abut vertically against and leave an end part terminal of a circuit board on a lower block 15.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relay connector for connecting a terminal and a tester disposed at an end of a wiring board to a circuit for inspection, and more particularly, to a clip-type contact of a probe with the terminal. The present invention relates to a clip-type relay connector that can easily connect and disconnect circuits.

[0002]

2. Description of the Related Art Inspection of a circuit board on which electronic components are mounted and a flexible printed circuit board connected to the circuit board are performed by testing tester terminals on terminals arranged at the ends of the circuit board and the flexible printed circuit board. Is connected by a circuit. However, in order to perform a quick inspection, it is necessary to easily and quickly perform circuit connection to terminals and separation after the inspection. In order to satisfy this demand, a clip-type relay connector has been proposed on the premise that a flexible printed wiring board is to be inspected.

A conventional clip type relay connector will be described with reference to FIGS. 2 and 3. FIG. In the figure, the thickness of the flexible printed wiring board 30 is constant, and conductor terminals 32, 32,... Are connected to a printed wiring circuit. An arm 35, also made of an insulating material, is mounted on a base 34, made of an insulating material, on which an end 31 of the flexible printed wiring board 30 is placed. Then, the arm 35 swings around the axis 37 so that the tip of the arm 35 can be freely separated from the mounting surface of the base 34. A probe 36 is provided on the arm 35, and the flexible printed wiring board 30 is provided on the base.
When the end of the arm 35 is placed near the mounting surface, the tip of the probe 36 contacts the conductor terminal 32 of the flexible printed wiring board 30. The probe 36 is circuit-connected to a tester (not shown) via a connection board 39. When the tip of the probe 36 abuts on the conductor terminal 32, the wiring circuit of the flexible printed wiring board 30 and the tester are circuit-connected. . Reference numerals 38, 38 denote coil springs for urging the distal end of the arm 35 toward the mounting surface of the base 34.

In this clip type relay connector, the tip of the arm 35 is attached to the base 3 against the urging force of the coil spring 38.
The end 31 of the flexible printed wiring board 30 is placed on the base 34 away from the mounting surface of the armature 4 and the arm 35 is swung by relying on the urging force of the coil spring. Is pressed against the conductor terminal 32.

[0005]

In the above-described conventional clip-type relay connector, since the arm 35 is a mechanism that rotates about the shaft 37, the tip of the arm 35 follows a circular orbit. That is, at the position where the arm portion 35 is close to the base 34, the probe 36 projecting at a right angle from the arm portion 35 abuts almost vertically on the mounting surface of the base 34,
When the arm 35 is separated from the base 34, the probe 36 is obliquely inclined with respect to the mounting surface of the base 34.

Therefore, in the conventional clip-type relay connector, the probe can be vertically abutted on the conductor terminal on a thin board such as a flexible printed circuit board.
Although good circuit connection can be ensured, there is a problem that the probe contacts the terminal that comes into contact with the circuit board with a certain thickness at an angle, which is likely to cause poor connection and fail to ensure good circuit connection. there were.

When the above-described inspection is performed on a circuit component having a connector provided at an end of a board, it is necessary to insert a probe having a certain length into an insertion opening of the connector. On the other hand, when the above-mentioned clip-type relay connector is applied, there is a problem that the probe is elongated, so that the inclination of the probe at the connector insertion port becomes more horizontal, and the probe cannot be inserted into the connector insertion port.

The present invention has been proposed in order to cope with such a situation, and regardless of the type of inspection object,
In particular, it is an object of the present invention to provide a clip-type relay connector capable of quickly and satisfactorily connecting and disconnecting a circuit to a thick circuit board or a connector installed at an end of the board.

[0009]

In order to achieve the above object, a clip-type relay connector according to the present invention comprises: a lower clip having a lower block mounted on an end of a substrate to be inspected mounted at the end; An upper clip pivotally mounted on the lower clip so as to be rotatable while being urged downward; a slide shaft provided on the lower clip and standing upright on the lower block; and a tip of the upper clip An upper block which slides up and down along the slide shaft by rotation of a portion, and a probe which is provided to project downward from the upper block are provided.

Further, the upper and lower blocks can be exchanged into necessary forms according to the form of the substrate to be inspected.

[0011]

According to the clip operation of the upper clip and the lower clip, the lower block on which the end of the substrate to be inspected is placed and the upper block on which the probe is mounted move up and down in parallel. Therefore, the probe always comes into contact with the edge of the substrate to be inspected perpendicularly, and good circuit connection is possible regardless of the substrate form such as the thickness and depth of the substrate. In addition, the adoption of the clip mechanism enables quick connection and disconnection of circuits as in the past. In addition, by changing the upper and lower blocks to a required form, quick and good circuit connection and disconnection can be always performed on an arbitrary form of substrate.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view of a clip-type relay connector according to one embodiment of the present invention. FIG. 7A shows a state in which the clip is released. The clip-type relay connector 1 causes an end terminal of a circuit board or the like mounted on the lower block 15 to come into contact with or separate from a probe 19 provided on the upper block 16 by a clip operation of the lower clip 11 and the upper clip 12. The probe 19 is brought into contact with an end terminal of a circuit board or the like and a circuit connection is made between the end terminal and a tester terminal for inspection. Where 20
Is a substrate for connection to a tester.

The structure will be described in detail. An upper clip 12 is attached to a lower clip 11 by a shaft 13 at a bracket portion 11a. Therefore, the upper clip 12 is rotatable around the axis 13, and the tip portion of the upper clip 12 is swingable up and down around the axis 13. The operating portion of the upper clip 12 is urged upward by a spring 21, that is, the distal end portion is urged downward.

A lower block 15 is mounted on the distal end side of the lower clip 11 by detachable fixing means such as screwing. Further, several slide shafts 17 are provided upright on the tip side of the lower clip 11 from the shaft 13 in a direction perpendicular to the mounting surface of the lower block 15. And
A slide block 18 is mounted on the slide shaft 17 so as to freely slide up and down along the slide shaft 17.

The slide block 18 is linked by a pin 14 to a long hole 12a formed at the tip of the upper clip 12. Also, the slide block 18
An upper block 16 is mounted on the upper surface of the device by detachable fixing means such as screwing. The upper block 16 has an insertion hole through which the slide shaft 17 passes. With the clip open, slide block 1

FIG. 1B shows a state in which the clip is operated against the urging force of the spring. Upper clip 1
When the user operates the button 2 downward, the tip portion of the upper clip 12 swings upward about the shaft 13. As a result, the slide block 18 link-coupled to the distal end portion of the upper clip 12 translates upward along the slide shaft 17. In other words, the upper block 16 attached to the slide shaft moves up and down by the clip operation. Therefore, the probe 19 mounted on the upper block always moves while maintaining a vertical state, and vertically contacts and separates from an end terminal such as a circuit board on the lower block 15.

FIG. 1 shows a state in which an object to be inspected having a connector 23 mounted on an end of a circuit board is placed on the lower block 15. Even in such a case, the connector 23
The probe 19 is inserted vertically to the insertion opening of the connector 19, and the contact / separation between the probe 19 and the terminal located deep in the connector can be performed smoothly. Further, depending on the form of the circuit board, there are some which are difficult to hold on the lower block 15 and those which need to change the length of the probe 19. For these, upper and lower blocks 15, 1
