Plug connector, controller and electric vehicle

Abstract

The invention relates to a plug connector, a controller and an electric vehicle. The plug connector comprises a plug connector body; a small pin part and a large pin part are formed on the plug connector body; the small pin part is provided with a plurality of jacks penetrating through the plug connector body, pins are inserted in the jacks, and the bottom of the plug connector body surrounds at least one jack to form a recessed first sealing groove; a plurality of distributor plates are arranged at the large pin part, slots penetrating through the plug connector body are arranged among the distributor plates, plug sheets are inserted in the slots, a recessed second sealing groove is formed in the bottom of the plug connector body around at least one slot, and a second sealing module and a first sealing module are arranged in the first sealing groove and the second sealing groove to realize sealing and waterproofing; the controller and the electric vehicle both comprise plug connectors. Sealing and waterproofing of the plug connector body and integration and combination of the plug connector interface are achieved, use and maintenance are facilitated, and meanwhile the situation that the interface is prone to being connected with a wrong wire is improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a connector, a controller and an electric vehicle using the connector. Background technique [0002] With the rapid development of the electric vehicle industry, the electric drive integrated system has gradually become a development trend. The integrated design of the controller can realize the miniaturization and light weight of the product, which is conducive to the layout and weight reduction of the whole vehicle. [0003] The electric vehicle controller and multiple electronic units of the vehicle need signal connection, which is connected through a combination of multiple sets of terminal blocks; at present, the wiring of many controllers is still the old-fashioned connection between the internal lead wire and the external wiring harness, which is easy to cause wiring harness damage during use. It will fall off, and it is easy to cause wiring harness e...

Problems solved by technology

[0003] The electric vehicle controller and multiple electronic units of the vehicle need signal connection, which is connected through a combination of multiple sets of terminal blocks; at present, the wiring of many controllers is still the old-fashioned connection between the internal lead wire and the external wiring harness, which is easy to cause wiring harness damage during use. It will fall off, and it is easy to cause wiring harness errors due to excessive wiring; at present, most terminal structures are directly exposed to the outside without any shelter. Long-term exposure will cause rapid aging of components and reduce service life. The approximation is also very high, and it is easy to insert wrongly when plugging in, resulting in the failure of the corresponding function, seriously causing damage to the controller, and also causing confusion in the external wiring harness. There are great difficulties in use and subsequent maintenance. , and the controller with higher requirements for waterproof level also caused great difficulties in waterproofing
