Description

Technical Field

[0001] The utility model relates to the technical field of remote control test fixtures, in particular to a universal combined test fixture. Background Art

[0002] During remote control production, ensuring product functionality and reliability is crucial. To this end, manufacturers typically use dedicated test equipment to perform a series of functional tests on remote controls. These tests verify various functions of the remote control, such as signal transmission and button response, to ensure that its performance in actual use meets design requirements.

[0003] Traditional testing methods typically involve using a test fixture, onto which the remote control is placed and powered up for subsequent functional testing. However, existing technologies have several limitations. Specifically, traditional test fixtures are often equipped with built-in dummy batteries that simulate the operating conditions of real batteries, allowing the test equipment to power on the remote control.

[0004] The problem is that when the test model needs to be replaced, the operator must remove the dummy battery and the air pipes and cables connected to it. This not only increases the workload of disassembly and assembly, prolongs the changeover time, but also increases tooling costs. In addition, frequent disassembly and assembly processes may cause damage to the dummy battery and its connectors, further increasing maintenance costs and downtime.

[0005] Therefore, in order to improve production efficiency and reduce costs, we propose a universal combined test fixture. Utility Model Content

[0012] Furthermore, the adjusting mechanism includes two guiding plates fixed to the upper end of the base plate, and transverse grooves are formed on the end faces of the guiding plates;

[0013] Wherein, the side of the jig plate is slidably connected to the transverse groove through a connecting member.

[0014] Furthermore, a locking member is threadedly connected to the side of the connecting member. A part of the locking member slides in the transverse groove, and the end abuts against the guiding plate.

[0015] Furthermore, a longitudinal groove is formed on the end face of the connecting member, and a locking member for fastening the connecting member and the jig plate is arranged in the longitudinal groove.

[0016] Furthermore, a positioning opening is formed on the side of the jig plate, and the connecting member is placed in the positioning opening.
