Abstract

PROBLEM TO BE SOLVED: To simplify an assembling operation so that the manufacturing time of an inspection jig is shortened and to provide an inspection jig which deals with a narrow pitch. SOLUTION: When a lead wire is connected, a rivet-shaped contact is inserted into a contact board in advance, and a connector with a lead wire is lastly inserted into the contact in a state that a plunger board, a spring board or the like is assembled. The inspection jig which deals with the narrow pitch has a structure in which the position of a contact coming into contact with a spring is deviated, and the pitch between contacts is made wider than the pitch between plungers.

2. Description of the Related Art A method for inspecting the continuity of a printed wiring board which has been increased in density has been adapted to a narrow pitch by directly incorporating a spring and a plunger into a board without using a case using a thinner probe. As an example, as shown in FIG. 3, the protection board (13) and the spring board (1)
4), a plunger (12), a spring (15), and a contact (17) are built in three boards of a contact board (16). Here, the hole made in the spring board allows the spring to move freely and pushes the plunger. On the other hand, the holes formed in the protection board and the contact board are smaller than the holes formed in the spring board, so that the plunger and the contact do not fall out due to the reaction force of the spring. The contact at this time is previously joined to the lead wire (18) by soldering or caulking.

In a conventional printed wiring board continuity test, an inspection jig having a structure in which a spring and a plunger are put into a pin board and pressed by a protection plate is used.
In order to incorporate the contacts into the contact board, it is necessary to pass the lead wires through the holes in the contact board because the contacts are already connected, and they must be single wires. Flat cable cannot be used. All of these processes have poor workability and take time.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. In FIG. 1, the plunger (1) is sandwiched between the protection plate (2) and the fall prevention board (3). The plunger shape is such that the diameter of the middle part is larger than the diameter of both ends, and both the protection plate and the fall prevention board have different hole diameters in the middle of the plate. The jar can be held. On the other hand, the above-mentioned plunger board is incorporated in a place where the contact board (6), the contact (7) and the spring board (5) are combined with the spring (4). At this time, the plunger can freely move up and down in the board, and appropriate conduction can be obtained by the reaction force of the spring. The contacts are connected by inserting a connector sleeve (8) to which a lead wire (9) is connected from the back of the jig after assembling the jig.
