Vehicular combination switch testing jig

Abstract

The invention discloses a test fixture for a combination switch for a vehicle, which comprises a positioning shaft with a ring platform installed on a bottom plate, a round hole inside the positioning shaft, an L-shaped guide groove on the side wall of the positioning shaft, and the lower end of the spinning shaft located in the round hole Inside, a guide pin is installed on the side wall of the spinning shaft. The guide pin is located in the L-shaped guide groove. The upper end of the spinning shaft is fixed with a spinning wheel and a pressing plate. There is an arc groove on the pressing plate. There are contacts at the bottom of the pressing plate. The outer cover of the spinning shaft between the pressing plate and the pressing plate is equipped with an automatic reset block that can slide axially. The automatic reset block is connected with a pressure rod. The left and right sides of the positioning shaft are respectively equipped with first and second elastic contact groups, and the first elastic contact group can move horizontally and vertically. The invention satisfies the test requirements of combination switches with various structures, avoids the occurrence of contact voltage drop detection errors, and has a simple and practical structure.

Description

technical field [0001] The invention relates to a fixture mechanism, in particular to a fixture for testing a vehicle combination switch. Background technique [0002] At present, the conventional vehicle combination switch test adopts the docking sheath to install a slider to move back and forth in a single direction. If some products with more complex structures are tested, different test fixtures need to be replaced, which is time-consuming and laborious. At the same time, the following problems exist: [0003] 1. A test fixture can only produce one-way movement, the test work is intensive and the efficiency is low; [0004] 2. The vehicle sheath and the product connector will be worn out after long-term plugging and unplugging, which will affect the detection of product contact pressure drop; [0005] 3. It is inconsistent with the actual loading status of the vehicle combination switch. [0006] Combining the above problems, through the analysis of the typical struct...

AI Technical Summary

Problems solved by technology

[0007] In order to overcome the time-consuming and labor-intensive problem of the lack of special fixtures for the existing vehicle combination switch test, the present invention provides a vehicle combination switch test fixture, the contacts of the fixture can move in two directions; the joints adopt point contact mode, Can avoid the contact voltage drop detection error caused by the wear and tear of the vehicle sheath
