Overview of overloaded connectors

Summary

Heavy-duty connector is mainly used for electrical or signal connection between different devices or functional units, which provides great convenience for installation and maintenance of complex control equipment.

Heavy-duty connectors are widely used in construction machinery, textile machinery, packaging and printing machinery, tobacco machinery, electric locomotives and petrochemical power, which need electrical and signal connections.

Application occasion. At present, it has become the international standard electrical connection components.

Plug-in

The basic components of overloaded connectors are: I. connectors II. protective mounting housing III. connector accessories.

The connector is made of VO flame retardant material, which meets UL94 VO. The maximum working temperature is 125.

But after special treatment with PPS, it can withstand external temperature up to 180 degrees Celsius. The connection modes of conductive terminals of different sockets are roughly as follows:

Screw pressing, cold pressing needle connection, shrapnel pressing connection, coil needle connection, axial bolt pressing connection, rapid pressing connection, etc.

Installation housing

Cast aluminium material is usually used for protective installation housing. The surface of the shell is treated by powder coating or self-extinguishing thermoplastic material (special series).

It can withstand impact or mechanical pressure. Seals between the same enclosures can make the protection level of the connector enclosure up to IP65 (EN60529).

The attachment includes various cable joints and different housing forms. Various accessories provide different solutions for different installation requirements. The form of shrapnel pressing,

Coil needle wiring, axial bolt pressing, rapid pressing, etc.
