Self-stripping wire electric coupler and contact piece thereof

Abstract

The invention relates to the field of electric couplers, in particular to a self-stripping wire electric coupler and a contact piece thereof. The front end of the electric coupler serves as an inserting end, the electric coupler comprises a front insulator and a back insulator which are sequentially arranged from front to back, the back insulator is detachably inserted in the front insulator to be in keying fitted with the front insulator, a casing is fixedly assembled on the front insulator, the contact piece is fixedly assembled in the front insulator, the back end of the contact piece is provided with a connection wire sleeve for a lead core of a lead to insert in, a notch is arranged at the back end of a sleeve wall of the connection wire sleeve, cutting edges are formed at an edge of an inner wall face of the connection wire sleeve close to the notch, a lead fixing sleeve is sleeved o the outside of the back insulator, the lead fixing sleeve is detachably connected with the casing, a thread hole which penetrates from front to back and is used for the lead to penetrate in is arranged on the back insulator, the connection wire sleeve of the contact piece extends to the corresponding to the thread hole, and a lead limiting structure is arranged on a hole wall of the thread hole. The self-stripping wire electric coupler and the contact piece solve the problem that leads of certain electric couplers are inconvenient to connect.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a self-stripping electrical connector and a contact piece thereof. Background technique [0002] The wiring of current electrical connectors all adopts the method of welding wire or crimping wire. But no matter which method is used, the wires need to be stripped, that is, the outer insulation of the wires is peeled off, and then the wires are welded to the contacts of the electrical connector with an electric soldering iron, or the wires are connected to the electrical connector with a crimping tool. The contacts are crimped. When carrying out the above-mentioned wiring operations, since special tools are required, it is impossible to complete the wiring at some construction sites without the above-mentioned corresponding tools, so the wiring is extremely inconvenient, and the above-mentioned wiring methods require a high professional level of the operator. The wiring quali...
