Basic Structural Member Of Connector

The basic structural parts of the micro electrical connectors are ① contact parts; ② insulation parts; ③ shells (depending on the variety); ④ accessories

1. Contacts:
It is the core part of the connector to complete the function of military grade electrical connectors. Generally, the contact pair is composed of a male contact and a female contact.

The male contact is a rigid part and its shape is cylindrical (round pin), square post (square pin) or flat (pin). The male contact is generally made of brass or phosphor bronze.

The female contact is the key part of the contact pair. It relies on the elastic structure to elastically deform when mating with the pin to produce elastic force to form close contact with the male contact to complete the connection. There are many types of jack structures, including cylindrical (split groove, necked), tuning fork type, cantilever beam (longitudinal slot), folded type (longitudinal slot, 9-shaped), box shape (square socket) and hyperboloid wire spring jacks.

2. Insulator:
Insulators are often called base or inserts, and their role is to arrange the contacts in the required position and spacing, and to ensure the insulation performance between the contacts and between the contacts and the housing. Good insulation resistance, voltage resistance and easy processing are the basic requirements for selecting insulating materials for processing into insulators.

3. Shell:
She11 is the outer cover of the military spec connector. It provides mechanical protection for the built-in insulation mounting plate and pins, and provides alignment when the plug and socket are mated, so that the connector is fixed to the device.

4. Attachments:
The accessories are divided into structural accessories and installation accessories. Structural accessories such as collars, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, seals, gaskets, etc. Installation accessories such as screws, nuts, screws, spring coils, etc. Most of the accessories are standard parts and universal parts.
