Claims (1)

[Claims for Utility Model Registration] 1. A mounting board that moves relative to the circuit board to be inspected, a wire guide body that is fixed through the mounting board and has an insulating property, and a wire guide body that is attached to the wire guide body and has an insulating property. It is equipped with a large number of wire beams, and the tip of each wire beam is brought into contact with a reference point on the circuit board to perform electrical measurement and inspection, and the contact pressure with the inspection point is obtained by buckling each wire beam. An inspection device for inspecting circuit boards, etc., which includes: a base end of the wire guide body;
In addition to providing an insertion hole through which the base end of the wire beam is inserted, a retaining portion is provided at the base end of the wire beam and abuts against the rear end wall of the insertion hole to prevent the wire beam from coming off toward the distal end side. , and a power supply connector is removably attached behind the base end of the wire guide body, and an electrical connection fitting provided on the power supply connector corresponding to each wire beam is connected to the retaining part of the wire beam from behind. An inspection device for a circuit board, etc., characterized in that it electrically connects to a wire beam and fixes the proximal end of the wire beam to a wire guide body through elastic contact. 2. The retaining part is a retaining ring fixed to the base end of the wire beam, a tapered hole-shaped guide is provided at the rear end of this ring, and the connecting fitting is a plunger that protrudes into the hole opened at the distal end surface of the power supply connector. 2. The apparatus for inspecting circuit boards and the like according to claim 1, wherein a conical portion at the tip of the plunger is pressed into the tapered hole-shaped guide. 3. An inspection device for circuit boards, etc., as set forth in claim 2 of the utility model registration claim, characterized in that the plunger is pressed toward the tip side. 4. An inspection device for circuit boards, etc., according to claim 1, wherein the main body of the power supply connector is attached to the wire guide main body with a guide pin and a fixing screw.
