Description

Wire end connector Technical Field The utility model relates to the field of connectors, in particular to a wire end connector. Background In the wire end connector, the limit structure of the terminal is generally inserted and assembled from top to bottom, the insulating shell needs to be correspondingly designed into a structure with a hollowed-out middle to meet the assembly requirement, and the insulating shell of the wire end connector is weak in structural strength and easy to break, so that the application requirements of a terminal product in the scenes of high impact resistance, strong bending resistance and the like can not be met. Meanwhile, the limit structure of the wire end connector cannot be pulled out after being installed, and the replacement requirement of the terminal after aging cannot be met. Based on the above-mentioned deficiency, it is necessary to design a wire end connector capable of improving structural strength and rapidly disassembling and replacing terminals, which can provide stable signal transmission function for terminal products in an application environment with high impact strength, and reduce maintenance cost of terminal equipment. Disclosure of utility model The utility model provides a wire end connector, which is characterized in that after the assembly mode of a terminal limiting structure is improved, the upper, middle and lower three directions of an area of an insulating shell, in which the terminal limiting structure is arranged, are not required to be hollowed out, the strength of the insulating shell can be enhanced, the strength requirement of a terminal product in various scenes is met, an elastic arm is additionally arranged in the terminal limiting structure to be elastically buckled with the insulating shell, and the terminal limiting structure is withdrawn by pulling and pressing the elastic arm, so that the terminal is quickly disassembled and replaced. The aim of the utility model is achieved by the following scheme: A wire end connector comprises an insulating shell, a crimping terminal and a limiting piece, wherein a terminal hole and a limiting groove are formed in the insulating shell, the crimping terminal is installed in the terminal hole along the length direction of the insulating shell, the limiting piece is inserted into the limiting groove from the side face of the insulating shell to limit the crimping terminal, the limiting piece comprises a connecting portion, a first cross arm, a second cross arm and an elastic arm, the first cross arm, the second cross arm and the elastic arm extend from two ends of the connecting portion respectively, one end of the elastic arm is provided with a protruding buckling portion, the buckling portion is buckled with the insulating shell elastically, and the crimping terminal can be rapidly disassembled and replaced by pulling the elastic arm. In the prior art, the terminal limiting structure is usually installed in the insulating housing in a vertical assembly mode, and the corresponding region of the insulating housing, where the terminal limiting structure is installed, needs to be designed into a hollow space for avoiding, and the terminal connector is connected only by the plastic at two ends of the insulating housing, so that the terminal connector is easy to break once being subjected to external force. The side surface of the insulating shell is provided with the limiting groove, one end of the terminal limiting piece is opened, the limiting piece is inserted into the limiting groove from the side surface of the insulating shell to fix the terminal, the hollow structure of the insulating shell is completely avoided in a side mounting mode, and the impact resistance of the terminal connector is greatly improved.
