What constitutes a connector

Are you interested in learning what constitutes a connector? Please read my article, I will tell you the components of the connector.


The contacts is the core part of the connector to complete the connection function. The contact pair is generally composed of a male contacts and a female contacts, and the connection is completed by the insertion of the female and male contacts.

The male contacts are rigid part that is cylindrical, square or flat in shape and are generally made of brass or phosphor bronze.

What constitutes a connector

The female contacts are the jacks, its a key component of the contact pair. It relies on the elastic structure to elastically deform when it inserted into the pin, and generates elastic force to form close contact with the male contact member to complete the connection. There are many types of jacks, such as cylindrical, tuning fork, cantilever beam, folding, box and double-curved wire spring jacks.


The insulators, also commonly referred to as base or mounting plates, its role is to arrange the contacts in the desired position and spacing, to ensure the insulation function for contacts and also between contacts and casing. There are nice insulation resistance, voltage resistance and ease of processing are the basic requirements for the selection of insulating materials into insulators.


The shell is the connector housing that provides mechanical protection for the built-in insulated mounting plate and pins, and also provides alignment when the plug and socket are mated, thereby securing the connector to the device.


The accessories are divided into structural accessories and mounting accessories. The structural accessories such as collars, positioning keys, locating pins, guide pins, coupling rings, cable clamps, seals, gaskets, etc. The nstall accessories such as screws, nuts, screws, coils, etc. The accessories are mostly standard and general.
