Description

Technical Field

[0001] The utility model relates to the technical field of signal connection structures, in particular to a signal connector with a pre-tightening structure. Background Art

[0002] Connectors are also called connectors, and are also called joints and sockets in China. They generally refer to electrical connectors, which are devices that connect two active devices to transmit current or signals. The male and female ends can transmit information or current after contact. They are also called connectors. Signal connectors, as a type of connector, are widely used in life.

[0003] At present, with the rise of new-type vehicles and the extensive application of low-capacity lithium batteries, there are more and more signal connectors for vehicle systems. The terminals of this connector generally have at least two terminals to realize signal transmission between various electronic components. The whole vehicle application is usually a male or female connector harness connected to an electronic component, and then connected to a male or female connector harness connected to another electronic component.

[0004] The signal connectors of light vehicles such as electric tricycles are simply connected together without a pre-tightening structure. Obviously, there is a risk of loosening when riding on bumpy roads or complex environments, which may cause the vehicle to be unable to drive and cause an accident. For this reason, we propose a signal connector with a pre-tightening structure to effectively solve the above-mentioned drawbacks. Utility Model Content
