The specific implementation mode is as follows:

the technical idea of the application is that a floating plate is respectively arranged on a fixed carrier plate and a pressure plate which moves up and down; the floating plate is suspended through an elastic piece. A positioning groove is arranged between the two floating plates for placing a piece to be tested. A group of probes are arranged on the pressing plate, the positions of the probes are matched with the positions of the contacts on the module to be tested, when the pressing plate is pressed downwards, the two floating plates clamp and position the piece to be tested, and the probes on the pressing plate penetrate through the probe holes of the upper floating plate from top to bottom to contact the contacts of the piece to be tested; on the other hand, the elbow clamp of the control pressure plate is provided with a self-locking mechanism, so that an operator can vacate two hands for testing.

The detachable tray is arranged on the lower floating plate, and the module to be tested is arranged on the tray, so that the module to be tested can be conveniently arranged on the ground and the lower part of the module to be tested, and the working efficiency is further improved.

The present application is explained with the technical solution shown in fig. 1 as an example:

the lower floating plate 2 is supported on the carrier plate 1 through an elastic piece; used for bearing the piece to be tested.

A pressing plate 4 capable of moving up and down is arranged above the lower floating plate 2; a pressure lever 9 on the pressure plate 4 is connected with a connecting rod 10 through a revolute pair, and the connecting rod 10 is connected with the elbow clamp 5 through a revolute pair; the elbow clamp 5 is respectively connected with the connecting rod 10 and the bracket 8 through two revolute pairs; the bracket 8 is fixed on the base; the elbow clamp, the pressure lever and the connecting rod together form a crank connecting rod system for controlling the lifting of the pressure plate.

The lower part of the pressing plate 4 is connected with the upper floating plate 3 through an elastic piece; the upper floating plate 3 is provided with a probe hole 31; the pressure plate 4 is provided with a probe 6. After the two floating plates clamp the piece to be tested, the probe extends out from the upper part and accurately contacts the contact of the piece to be tested through the positioning of the probe hole. In order to further improve the positioning accuracy, a positioning structure, such as a matched trapezoidal bump, a matched groove and the like, can be arranged on the contact surface between the two floating plates.

A tray 7 is also arranged; the tray is positioned by the tray positioning groove on the lower floating plate 2, and the module placing groove 71 is arranged on the tray 7; can set up the probe hole on the tray for the tray possesses the commonality on other types of test fixture, if can adapt to the test fixture that the probe stretches out from the below.

The pressure lever 9 is arranged in the sleeve 81 and can move up and down; the sleeve 81 is connected to the support 8. The elbow clip 5 is provided with a bend; the rotating shaft of the elbow clamp 5 connected with the connecting rod 10 is positioned at the bending part.

The connecting rod 10 is a connecting piece which is formed by combining two bent sheets and has a gap in the middle. It can be seen that in this embodiment, two symmetrical "n" shaped plate-like members are used as the connecting rod, and the gap between the two plate-like members is used to provide space for accommodating the rotating shaft seat on the bracket in the self-locking state (the portion between the two rotating shafts of the toggle clamp is collinear with the connecting rod and the pressing rod).

The elbow clip 5 is bent into a right angle. If the angle is an obtuse angle, the handle extends downwards in a pressing-down state, so that the installation of the piece to be tested is influenced; if the angle is acute, the operation is inconvenient in a lifting state; the right angle is selected to combine with human engineering, so that the operation is convenient, and the production manufacturability is better.

A guide post is arranged between the bracket 8 and the base; and two sides of the pressure plate 4 are sleeved on the guide posts and can move along the guide posts. The upper floating plate 3 is suspended below the pressure plate 4 through a spring and a guide rod; the floating plate 2 is connected with the carrier plate 1 through a spring and a guide rod. The purpose of various guide devices is to improve the precision and avoid the shaking when two suspension members contact.

The probe holes 31 on the upper floating plate 3 correspond to the positions of probes, and the probes 6 penetrate out of the probe holes 31 when the upper floating plate 3 is pressed towards the pressure plate 4.

The tray 7 is provided with a module placing slot 71. In this embodiment, a 10PIN module slot.

The tip of the probe 6 is downwards arranged on the pressure plate 4; the tail terminals of the probes 6 extend above the platen and are connected to wiring harnesses. The structure and the testing method of the wire harness connection tester belong to the prior art and common knowledge in the field, and are not described herein again.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
