Module for testing dielectric strength of automotive relay

Abstract

The invention provides a module for testing the dielectric strength of an automotive relay, which comprises a dielectric strength tester. The module is characterized by also comprising a high-voltage control module; and the high-voltage control module comprises a programmable control circuit, a high-voltage end switch and a low-voltage end switch, wherein the dielectric strength tester outputs high voltage and returns to the output low-voltage end of the dielectric strength tester through the high-voltage end switch, the automotive relay and the low-voltage end switch; the control of the programmable control circuit on the high-voltage end switch, the automotive relay, the low-voltage end switch and the dielectric strength tester comprises the following steps of: starting the dielectric strength tester to output high voltage, controlling the high-voltage end switch and the low-voltage end switch to complete the testing requirement of the dielectric strength of different connecting parts of the automotive relay, cutting off the dielectric strength tester to output the high voltage after the test is finished, and cutting off the high-voltage end switch and the low-voltage end switch.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, in particular to an automobile relay electric strength test module. Background technique [0002] Automotive relays need to adapt to various automotive environments, such as temperature environment, climate environment, humidity environment, etc. Dielectric strength is an important indicator to measure the ability of automotive relays to adapt to the environment. [0003] There are many types of automotive relay products, and the connection methods for the dielectric strength test of each type of product are different. Therefore, many connection methods can be derived from the dielectric strength test of automotive relays. [0004] There are two traditional methods for testing the electric strength of automotive relays. The first method is manual. According to the different connection methods of different products, the electric strength test is carried out manually one by one. The ...

[0004] There are two traditional methods for testing the electric strength of automotive relays. The first method is manual. According to the different connection methods of different products, the electric strength test is carried out manually one by one. The advantage of this method is that it is more flexible and can adapt to various The test requirements; the disadvantages are low production efficiency, easy to miss and make mistakes; the second method uses the logic control method to manufacture corresponding logic control boards corresponding to different test requirements, so as to replace the manual method to test the electric strength one by one. Advantages High production efficiency, no mistakes will be missed, disadvantages are relatively low flexibility, and cannot adapt to various testing requirements
