What are the most basic structures of the connector?
The production process of a connector is very complicated and complicated. It is derived from the structure of the connector. What is the basic structure of the connector? In the following, Konnra Electronics engineers will focus on the connector. Knowledge of basic structure. Generally speaking, the basic structure of the connector is inseparable from the four aspects of the contact piece, the insulator, the casing and the accessory. Below, our connector engineer will explain it to you one by one.
First, the contact
As a core component for completing the electrical connection function, it mainly consists of an anode contact member and a cathode contact member, and the electrical connection is completed by the insertion of the female and male contacts.
The anode contact is a rigid part that is cylindrical (round pin), square (square pin) or flat (tab). The anode contacts are typically made of brass or phosphor bronze. The cathode contact is a jack, which is a key component of the contact pair. The elastic structure is elastically deformed when the pin is inserted to generate an elastic force to form a close contact with the male contact member to complete the connection. There are many types of jacks, such as cylindrical (grooving, shrinking), tuning fork type, cantilever beam type (longitudinal slotting), folding type (longitudinal slotting, "9" shape), box shape (square socket) ) and double-sided wire spring jacks.
Second, the insulator
It is often referred to as a pedestal or mounting plate and its primary function is to align the contacts at the desired position and spacing and to ensure insulation between the contacts and between the contacts and the outer casing. Good insulation resistance, voltage resistance and ease of processing are the basic requirements for the selection of insulating materials into insulators.
Third, the shell
Often referred to as the outer casing (depending on the variety), it is part of the connector housing that provides mechanical protection for the built-in insulated mounting plate and pins, and provides alignment when the plug and socket are inserted, and then the connector Pinned to the device.
Fourth, the attachment

Accessories are divided into structural accessories and mounting accessories. Structural accessories such as collars, locating keys, locating pins, guide pins, connecting rings, cable clamps, seals and gaskets. Mounting accessories such as screws, nuts, screws and spring rings. The accessories are mostly standard and general.
