Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an auxiliary clamp for external connection of connectors. Background Art

[0002] Automotive connectors refer to connectors used in automotive electrical systems, and are mainly used to connect various automotive sensors, electronic control units, electrical devices, instruments, lamps and other electrical components. Connectors play a very important role in automotive electrical systems, and can realize functions such as signal transmission, power transmission, and data transmission between various electrical components. They are an indispensable part of automotive electrical systems.

[0003] Connectors are divided into locking connectors and non-locking connectors. The current non-locking connectors can only realize the mating function, and cannot achieve the matching connection and fixation with the hole position of the sheet metal. Usually, the fixation between the sheet metal and the connector is achieved by binding with cable ties, and the connector is bound and fixed to the sheet metal. However, the fixing method of cable tie binding is difficult to achieve accurate positioning of the connector installation position, and the installation firmness of the connector is poor, and the connector cannot be effectively fixed. There will be hidden dangers of shaking, abnormal noise and unstable signal transmission at the mating end, which directly affects the use effect and service life of the connector. Utility Model Content

[0008] As an improved technical solution, the sheet metal connection portion is located on one side of the connecting beam, the positioning clamping portion is located on the other side of the connecting beam, and the sheet metal connection portion and the positioning clamping portion are respectively arranged at both ends of the connecting beam.

[0009] As an improved technical solution, the sheet metal connection portion is a barbed rivet structure, and the sheet metal connection portion is compatible with the specifications of the mounting hole of the body sheet metal.

[0010] As an improved technical solution, the connecting crossbeam is provided with a material removal portion, and the material removal portion corresponds to the sheet metal connecting portion.

[0011] As an improved technical solution, a limit block is provided on the inner side of the bent connection section of the positioning clamping portion, and the limit block is adapted to the secondary lock limit groove structure of the connector. When the connector is in the clamping state, the limit block extends into the secondary lock limit groove of the connector.

[0012] As an improved technical solution, the first clamping jaw has an inclined first guide surface, the second clamping jaw has an inclined second guide surface, the first guide surface and the second guide surface are arranged opposite to each other, and the clamping channel is formed between the first guide surface and the second guide surface, and the clamping channel is arranged to gradually narrow along the direction approaching the limit block.
