Description

Technical Field

[0001] The utility model relates to the field of automobile LED lamp assembly testing, in particular to a fixture for a fool-proof device for automobile LED lamp assembly testing. Background Art

[0002] Car LED lights are vehicle lighting fixtures that use LEDs as light sources. Compared with traditional halogen lamps or xenon lamps, LED lights have many advantages. First of all, LED lights have higher brightness and better energy efficiency. LEDs have high luminous efficiency and can produce brighter light while consuming less energy. This means that LED lights can use electricity more efficiently than traditional bulbs and reduce energy waste.

[0003] When producing LED car lights, they need to be tested to see if the circuit boards are unobstructed. However, during the test, since the wiring harnesses connecting the substrates are consistent at both ends but the wire diameters are different, the test equipment cannot detect whether the wiring harnesses are plugged in reverse. In addition, the placement directions of the two substrates on the jig cannot be identified, which can easily lead to misplacement. Utility Model Content

[0004] Based on the above description, the utility model provides a fixture for testing a fool-proof device for an automotive LED lamp assembly to solve the problem that the existing LED lamp test fixture is not good at judging whether the wiring harness is plugged in reverse.

[0005] The utility model solves the above technical problems with the following technical solutions: A fixture for testing a foolproof device for an automotive LED lamp assembly, comprising a test fixture body;

[0006] A substrate positioning jig is installed on the top of the test jig body, and the number of the substrate positioning jigs is two, the two substrate positioning jigs are distributed on the left and right sides, and the tops of the two substrate positioning jigs are provided with a first positioning groove and a second positioning groove;

[0007] Circuit boards are disposed inside the first positioning groove and the second positioning groove.

[0008] Furthermore, a thick end clamping groove is formed on the top surface of the substrate positioning fixture, and the thick end clamping groove is connected with the first positioning groove.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, a thin end fixture is fixedly mounted on the top surface of the substrate positioning fixture, and a thin end fixing groove is provided on the top surface of the thin end fixture.

[0011] Furthermore, a clamping block is disposed on the top surface of the test fixture body, and the number of the clamping blocks is two. The two clamping blocks are distributed on one side of the two substrate positioning fixtures and close to one end of the second positioning groove.

[0012] Furthermore, a clamping assembly is disposed on the top surface of the substrate positioning fixture, and the clamping assembly includes a connecting seat, a pressing plate and a handle, and the connecting seat is fixedly mounted on the test fixture body.

[0013] On the basis of the above technical solution, the present invention can also be improved as follows.

[0014] Furthermore, one end of the pressing plate is connected to the connecting seat via a torsion spring and a rotating shaft, a handle is fixedly connected to the top surface of the pressing plate, and the bottom of the pressing plate is movably fitted with the top surface of the thin end fixture.

[0015] Furthermore, one end of the test fixture body is movably connected to a cover plate via a hinge, a pressure rod is fixedly installed at the bottom of the cover plate, a handle is fixedly installed on one side of the cover plate, and the cover plate and the test fixture body are connected via a hydraulic cylinder.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] 1. The utility model sets a substrate positioning fixture on the test fixture body to install the circuit board to be tested into the corresponding first positioning groove and the second positioning groove according to its shape, and cooperates with the thick end clamping groove to connect the thick end wire diameter. At the same time, the thin end clamp will fix the thin end wire diameter, so as to distinguish the thick end wire diameter from the thin end wire diameter and avoid the problem of incorrect connection between the two.

[0018] 2. By setting a positioning component on the test fixture body, it is convenient to use the pressure plate in the positioning component to further fix the thin-end wire diameter installed in the thin-end fixture to avoid the thin-end wire diameter being not fixed firmly due to its too thin wire diameter. At the same time, a pressure rod is set on the cover plate. As the cover plate is closed, the pressure rod presses the circuit board to ensure the stability of the circuit board in the first positioning groove and the second positioning groove.
