Quick automatic testing fixture for automotive connector

Abstract

The invention relates to a quick automatic testing fixture for an automotive connector. The quick automatic testing fixture comprises a base board (2), a PIN contact platform (3) and a testing circuit. The PIN contact platform (3) and the testing circuit are arranged on the base board (2). The testing circuit comprises a plurality of branch circuits which are connected with a power supply (41). The number of the branch circuits is same with the number of PINs of a to-be-tested connector. The branch circuits are parallelly connected. Each branch circuit is connected with the pressure contact switch (42) and a state display lamp (43) which are connected in series. The pressure contact switch (42) is arranged on the PIN contact platform (3). The position of the pressure contact switches (42) are in one-to-one correspondence with the PIN positions of the to-be-tested connector. Compared with prior art, the quick automatic testing fixture is advantageous in that the pressure contact switch is utilized for sensing on-and-off change of a corresponding branch circuit caused by a PIN pressure; whether the PIN is qualified is displayed through a state displaying lamp; and one-to-one testing of the PINs by an operator is not required, thereby preventing visual fatigue, reducing testing error rate and improving testing speed.

Description

technical field [0001] The invention relates to a tester for automotive electronic equipment, in particular to a quick automatic tester for automotive connectors. Background technique [0002] In order to achieve automatic control or transmission interaction, automotive electronic equipment needs to use a connector as a medium for signal transmission. The connector usually includes a housing and a PIN pin. One end of the PIN pin is connected to the wiring harness, and the other end is inserted into the communication interface of the corresponding electronic device. , PIN pins are usually arranged in an array. [0003] During the transfer process of the connectors at different stations, although they are individually placed in baskets with partitions, bumps and impacts cannot be avoided, causing the PIN pins in the connectors to drop, truncate or tilt, resulting in the need for repairs on the connectors or scrapped. [0004] At present, many connector products rely on manua...

[0003] During the transfer process of the connectors at different stations, although they are individually placed in baskets with partitions, bumps and impacts cannot be avoided, causing the PIN pins in the connectors to drop, truncate or tilt, resulting in the need for repairs on the connectors or scrapped

[0004] At present, many connector products rely on manual inspection and tool microscope projection to check whether there are broken pins and structural abnormalities in the product. This method is slow, inefficient, and expensive, and is prone to visual fatigue; The deflection angle is difficult to identify by manual and microscope, and the flow of defective products into the market will cause great risks
