Connection plug-in for automatic transmission end of line test bench

Abstract

The invention discloses a connection plug-in for an automatic transmission end of line test bench, which comprises a plug-in seat (1). The plug-in seat (1) is provided with a plurality of mounting through holes (11); each mounting through hole (11) is internally provided with a terminal mounting casing (2); one end of the terminal mounting casing (2) is fixedly connected with a connection wire, and an elastic terminal (3) is inserted in the other end; the plug-in seat (1) is also provided with a limiting groove (4); and the limiting groove (4) is matched with a stiffened plate inside a to-be-tested automatic transmission harness plug-in. the purpose of quick connection can be realized, terminal connection reliability and influences on the transmission harness terminal by pressure in the case of pressing can both be considered, and better durability is realized.

Description

technical field [0001] The invention relates to a connecting plug-in, in particular to a connecting plug-in used for an automatic transmission off-line test bench. Background technique [0002] At present, automatic transmissions are more and more widely used in automobiles because of their good driving comfort and convenient and quick maneuverability. The automatic transmission electronic control components are generally composed of the transmission control unit TCU, various sensors, solenoid valves and connecting wiring harnesses. In order to ensure the normal function of the automatic transmission, the transmission factory generally designs the automatic transmission assembly off-line test, through the mechanical connection and electrical connection of the automatic transmission and the off-line test bench, the test is carried out according to certain test conditions, and the transmission is running , the test bench (including the test program) collects signals, controls...

AI Technical Summary

Problems solved by technology

[0003] The connecting plug-ins used in the existing off-line test bench generally refer to the plug-in design of the vehicle wiring harness. The shape is consistent with the plug-in used in the vehicle wiring harness, and there is no locking function; These terminals will be worn and squeezed when they are inserted and pulled out, which will affect their life, or the modified terminals will be in contact with the end faces of the transmission harness terminals. The connection reliability of this modified terminal is poor

Therefore, when designing the terminals, it is necessary to consider not only the reliability of the terminal connection, but also the influence of the pressure on the terminals of the transmission harness during compression, and there is a contradiction between the two in balance.
