UK wiring terminal and manufacturing method thereof

Abstract

The invention relates to the technical field of electrical connection, in particular to a UK wiring terminal and a manufacturing method thereof. The UK wiring terminal comprises a shell and an electricity receiving block, and the shell comprises a framework body and a filling body; and the framework body is of a frame type structure. The filling body is arranged between the frameworks of the framework body, and the framework body and the filling body are prepared through the steps of injection molding, pressure maintaining, filling and hot melting. As the UK wiring terminals are fixed on the guide rail in use, the application environment of the UK wiring terminals has corresponding requirements on aging and insulating properties of the UK wiring terminals, and the UK wiring terminals are widely applied to a circuit system, so that the cost is reduced and the reliable service life of the UK wiring terminals can be damaged by using a certain proportion of returned materials for manufacturing; therefore, the framework body formed by new material injection molding is arranged to form the shell frame, and the returned material is supplemented, injected and filled between the frames of the shell, so that the effective service life of performance parameters in use is maintained, the cost of raw material expenditure is reduced, and the competitiveness of UK wiring terminal products isimproved.

Description

technical field [0001] The invention relates to the technical field of electrical connection, in particular to a UK terminal and a manufacturing method thereof. Background technique [0002] The terminal block is used to facilitate the connection of wires. It installs metal sheets of conductive materials in insulating plastics, and has mounting holes for inserting wires at both ends, and has fasteners for installing wires, which replaces the wires in the wire connection. The welding or winding connection method improves the firmness and reliability of the wiring and avoids circuit failures caused by loose wiring. The UK terminal has universal mounting feet, which can be installed on U-shaped guide rails and G-shaped guide rails, and it is closed Type bolt guide holes are convenient for operation, and there are unified accessories and grounding terminals in the terminals of the same section level; for the introduction of UK terminal blocks, please refer to, Youxin, Maintenanc...

AI Technical Summary

Problems solved by technology

[0003] The manufacture of terminal blocks is mainly based on mold injection molding. The key withstand voltage and aging resistance performance parameters of terminal blocks are closely related to the quality of injection molding materials. However, new plastic materials are used in injection molding materials, which increases the cost of terminal blocks. If there are too many recycled plastics, the quality of the terminal block manufacturing will be reduced, leaving a safety hazard in the application.

[0004] There are also some technical solutions about UK terminals and their manufacturing methods in the prior art. For example, a Chinese patent with application number 2012101667422 discloses a UK zinc alloy terminal. Rows of symmetrical arrangements are formed by die-casting zinc alloy materials and separated by stamping; the manufacturing method of the UK terminal includes the following steps: first heat the zinc alloy material in a high-temperature furnace to a molten state; then melt the zinc alloy material into a liquid state The alloy material is injected into the prepared one-piece die-casting mold; the mold is pressurized, and two rows of symmetrically arranged UK zinc alloy terminals are formed by one-piece die-casting, and then cooled; the cooled one-piece UK zinc alloy terminal is taken out from the mold Terminals, each terminal is a square cylinder with non-closed ends at both ends, and the bottom of the terminals between the multiple terminal rows formed in one piece is provided with connecting ribs connecting the two; the integrally formed UK zinc alloy terminal Put it on a fully automatic multi-head tapping machine, tap the round through holes on multiple terminals at one time, and then stamp and separate the multiple terminals connected into one piece into a single UK zinc alloy terminal; finally tap After wire separation, the single UK zinc alloy terminal is drum-grinded and then nickel-plated. The finished terminal processed in this technical solution has stable performance, low cost and high production efficiency; Under the premise of satisfying the performance of the injection molding material of the casing, the problem of high injection molding cost of new plastic materials
