The fixing assembly 100 provided by the embodiment of the present application is used for fixing a crimping structure (not shown), wherein the crimping structure includes a terminal (not shown) and a wire 91 arranged on the terminal, the fixing assembly 100 includes a main body portion 10, the main body portion 10 includes a first surface 101, a groove 11 is arranged on the first surface 101, and the crimping structure is fixed in the groove 11.

When using this application fixed component 100 to fix the crimping structure, the crimping structure restraint that wire 91 and terminal are constituteed is fixed in fixed component 100 in, the crimping structure exists with the mode of little assembly with fixed component 100 jointly, has avoided wire 91 to take place to take off the condition of hank in the commodity circulation transportation or pencil assembly installation, and then has guaranteed that the lay length of wire 91 satisfies corresponding requirement, has improved signal transmission's stability.

Moreover, when the crimping structure and the fixing component 100 are present in the wire harness assembly in a small assembly manner, the transportation and supply of the ethernet product can be facilitated, so that the working efficiency is effectively improved.

The main body 10 of the fixing assembly 100 should be matched with an external device to be connected, and the shape and size of the main body 10 should be determined according to the corresponding situation, which is not specifically described and limited herein. The main body 10 includes a first surface 101, and a groove 11 is recessed in the first surface 101, and the groove 11 is used for constraining and fixing the crimping structure.

The crimping structure includes a wire 91 and a terminal, the wire 91 is crimped on the terminal to form the crimping structure together, the wire 91 may be a wire 91 twisted together in the ethernet twisted pair 90, it can be understood that the wire 91 is not limited to use only the wire 91 in the ethernet twisted pair 90, but also may be other wires 91 meeting the corresponding functional requirements, and the type and twisting manner of the wire 91 are not limited herein. For convenience of description, the embodiment of the present application takes the conductor 91 in the ethernet twisted pair 90 as an example for detailed description, and other types and twisting manners of the conductor 91 can be assembled and connected with reference to the following description. When the wires 91 of the ethernet twisted pair 90 are used, the wires 91 twisted together at the ends of the ethernet twisted pair 90 are separated, and each wire 91 is crimped with a corresponding terminal, thereby forming a crimp structure.

In one embodiment, there are at least two grooves 11, and at least two grooves 11 are spaced apart from each other. When recess 11 is at least two, fixed subassembly 100 is applicable to fixed electric wire that is formed by many wires 91 transposition together, and when the interval sets up between two at least recesses 11, carries out the crimping back at many wires 91 that above-mentioned electric wire end was separated respectively with the terminal, forms a plurality of crimping structures, and every crimping structure homoenergetic can be independent restraint be fixed in a recess 11 in, can not contact the influence between every crimping structure, has avoided crimping structure to damage, has guaranteed the stability of model transmission.
