Detailed Description

The following description of the technical solutions in the embodiments of the present utility model will be clear and complete, and it is obvious that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1, a split groove terminal of an electrical connector includes a terminal body 1, one end of the terminal body 1 is provided with a socket tube 2 integrated with the socket tube, the other end is provided with a wiring tube 3 integrated with the socket tube, split grooves 21 are circumferentially distributed on the socket tube 2 around the axis thereof to divide the wiring tube into a plurality of contact reeds 22, an annular limit groove 23 is provided on the outer wall of the front end of the socket tube 2, and a tightening spring 4 is sleeved on the limit groove 23. The utility model adopts the tightening spring 4 to tighten the contact spring 22, when the matched terminal is inserted into the plug tube 2, the contact spring 22 expands outwards, so that the tightening spring 4 deforms to generate elastic force to counteract the contact spring 22, the connection stability of the terminals is improved, and the conductivity between the terminals is ensured; the utility model is also provided with the limit groove 23, so that the tightening spring 4 is not easy to move on the plug tube 2 to influence the tightening function.

Further, an arc-shaped elastic deformation portion 24 is provided at the connection portion of the insertion tube 2 and the terminal body 1. The arcuate configuration of the elastically deformable portion 24 facilitates elastic deformation thereof upon insertion of the mating terminal, and improves bending resistance of the material, extending the life of the product.
