On-site wire connector

Abstract

The invention relates to a field-made wire connector, comprising a metal shell with a plug-in end at the front end, an insulator with a built-in contact piece installed in an axial installation hole of the metal shell, and a wire-pressing screw pierced through a screw hole on the contact piece , a radial installation gap is set between the insulator and the hole wall of the axial installation hole, an insulating anti-falling part is fixed in the radial installation gap through a fixing structure, and a pressure supply line is arranged between the insulating anti-falling part and the insulator The movable cavity of the screw reciprocating along the axial direction corresponding to the screw through hole, the insulating anti-releasing part is provided with a screwdriver hole corresponding to the position of the screw through hole for the corresponding screwdriver to apply torque to the crimping screw after passing through, A screw-off prevention structure is provided for cooperating with the thread-pressing screw to stop and limit the movement of the thread-pressing screw away from the direction of the screw hole. The invention provides an on-site wire connector which can ensure that the wire pressing screw is prevented from falling off, and can also ensure that the wire pressing screw and the metal shell are not connected.

Description

technical field [0001] The invention relates to a field-made wire connector for transmitting electrical signals. Background technique [0002] The existing field-made wire connectors include a housing, an insulator with a built-in contact is installed in the axial mounting hole of the housing, and the contact is provided with a core perforation for the corresponding cable core to wear, and a hole for the core perforation Screw holes are arranged on the wall, and crimping screws for fixing the cable cores in the corresponding wire core holes are installed in the screw holes. In actual use, in order to prevent the crimping screw from coming out of the screw hole, it is often necessary to set up a corresponding anti-loosening structure to limit and prevent the crimping screw from coming off. The existing anti-loosening structure is to set a corresponding closing port on the metal shell structure, this method has great limitations, because the screw needs to be attached to the ...

Problems solved by technology

In actual use, in order to prevent the crimping screw from coming out of the screw hole, it is often necessary to set up a corresponding anti-loosening structure to limit and prevent the crimping screw from coming off. The existing anti-loosening structure is to set a corresponding closing port on the metal shell structure, this method has great limitations, because the screw needs to be attached to the metal shell to achieve anti-off, which leads to the fact that the screw must be in contact with the metal shell, which makes the existing anti-off The structure has great limitations, and it cannot be used in the working environment that requires no contact between the crimping screw and the metal shell; in addition, it is also necessary to process a matching structure on the crimping screw to cooperate with the closing structure , which increases the difficulty of screw processing and increases the production cost of crimping screws
