Description

Technical Field

[0001] The utility model relates to the field of circuit board detection, and particularly relates to a test bracket for a fixed module test fixture. Background Technique

[0002] During the production process of circuit boards, module test fixtures are usually used. However, the traditional module test fixtures are generally fixed by gluing. This method has poor versatility. When changing test items, it is necessary to use alcohol to remove the fixing glue. After removing it and replacing the bakelite, it is necessary to re-glue and fix. Such repeated operations waste labor time and also waste the costs of alcohol and glue. At the same time, on the panel with the switch design, it is necessary to lower the head to fully operate the switch during testing, which does not achieve the realization in the same area, reducing the effect. At the same time, since the fixture generally needs to be at an inclined angle during testing, so that the tester can have a good posture to test the circuit board, but during the use process, the problem of loosening of a single fixture may occur. For the inclined fixture, the fixation is unstable, and the test may not be able to be completed quickly.

[0003] In order to solve the problems such as the mold test fixture can stably test, does not require gluing and fixing, and improves the detection efficiency, a simple optimization scheme is provided now. Content of the Utility Model

[0004] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0005] A test bracket for a fixed module test fixture, comprising: bakelite, a rotating disk, a bracket, a rotating shaft and a fixing plate. The bakelite structure is a rectangular structure. A rotating disk is installed on the upper surface of the bakelite. A bracket is installed on the upper surface of the rotating disk. One end of a rotating shaft is symmetrically connected to the inner side of the top of the bracket. The other end of the rotating shaft is connected to a fixing plate. Among them, both sides of the bracket are triangular structures, the bottom of the bracket is a rectangular structure, a control button is installed on the right side of the bracket, through holes for handles are opened on both sides of the bracket, a fixing seat is fixed at the center position of the fixing plate, and a clamping plate is installed on the upper surface of the fixing seat.

[0006] Preferably, the clamping plate includes: a wrench, a clamping block, a limiting block, a bottom plate, a positioning plate, a moving rod, a baffle, a spring, a telescopic rod, a positioning groove, an installation groove and a positioning spring. The bottom plate structure is a rectangular structure. Clamping blocks are symmetrically installed at both ends of the bottom plate. A wrench is fixed on the upper surface of the clamping block. A limiting block is fixed on the upper part of the clamping block near the edge of the bottom plate. Three positioning grooves are opened inside the clamping block, and the three positioning grooves are distributed in a "pin" character structure. A positioning plate is installed inside the positioning groove, and one end of the positioning plate is connected to the telescopic rod, and the telescopic rod penetrates into the positioning spring.

[0007] Preferably, three mounting grooves are provided on the side edges at both ends of the base plate, a baffle is slidably installed in the mounting groove, the end face of the baffle is fixed to one end of the moving rod, the other end of the moving rod is fixed to the clamping block, a spring is installed in the mounting groove, one end of the spring is against the baffle, and the other end of the spring is against the edge of the base plate.

[0008] Preferably, the two bottom positioning plates initially abut against the upper portion of the positioning slot, the middle positioning plate initially abuts against the lower portion of the positioning slot, and the three positioning plates extend out of the inner surface of the clamping block.

[0009] Preferably, the button is connected to the bakelite via an electric wire, and the bakelite is provided with a current output line connected to the test fixture. Beneficial Effects

[0010] The side of the bracket of the utility model is designed as a triangle, so the button can be installed on the side bevel while ensuring a certain inclination angle of the button. At the same time, the triangular structures on both sides can improve the supporting stability of the bracket and improve the stability of the fixation of the test fixture. At the same time, since the bracket is equipped with a rotating disk and a rotating shaft, the test fixture can be adjusted to any angle to achieve the most comfortable test posture for the tester, thereby improving the test efficiency of the tester.

[0011] The utility model provides an acceleration and a positioning plate. When performing a test, the acceleration can provide a lateral clamping force to clamp the test fixture firmly. When cooperating with the positioning plate to clamp the test fixture longitudinally, the stability of the test fixture can be further guaranteed, and the test fixture is not easy to slide when tilted. At the same time, the positioning plate can be used to clamp relatively flat and thin fixtures, and can also meet the needs of relatively thick fixtures. At the same time, when the fixture is provided with a positioning groove, the positioning plate can also be inserted into the positioning groove for fixing and stabilizing, thereby meeting the stability requirements of different fixtures. The structure is convenient and simple, and the adaptability is strong. BRIEF DESCRIPTION OF THE DRAWINGS
