Abstract

The invention relates to a wiring terminal which includes a wiring board which is made of a conductive material. The wiring board is at least provided with one wiring hole. One end part of the wiring board extends inside one insulator and is connected to the insulator. The matrix surface of the insulator is provided with a plurality of ring-shaped disks which includes first ring-shaped disks and second ring-shaped disks. The first ring-shaped disks and the second ring-shaped disks are spaced with a preset distance, and the diameter of each first ring-shaped disk is greater than that of each second ring-shaped disk. The other end of the insulator is provided with a cone-shaped transition part of which the other end is connected to a connection part of a cable and is connected to the end part of the wiring board that extends inside the insulator. The center lines of the insulator and the cone-shaped connection part are intersected at an angle of 120-130 degrees. The thickness in the centers of each first ring-shaped disk and each second ring-shaped disk are greater than the thickness on the edges. According to the invention, the wiring terminal can effectively increase creep distance, protects usage and operation life of a circuit.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a connection terminal. Background technique [0002] Terminal block is an accessory product used to realize electrical connection, which is industrially divided into the category of connectors. With the increasing degree of industrial automation and stricter and more precise industrial control requirements, the amount of terminal blocks is gradually increasing. With the development of the electronics industry, the use of terminal blocks is increasing, and there are more and more types. At present, in addition to PCB board terminals, there are hardware terminals, screw cap terminals, spring terminals and so on, which are most widely used. The terminal block is used to facilitate the connection of wires. It is actually a piece of metal sealed in insulating plastic. There are holes at both ends for inserting wires, and there are screws for fastening or loose...
