Basic structure of the connector
The basic structural components of the connector are ① contact parts; ② insulator; ③ shell (depending on the variety); ④ accessories.
1, contact parts (contacts) is the core parts of the connector to complete the electrical connection function. Generally by the positive contact parts and the negative contact parts to form a contact pair, through the Yin and Yang contact parts of the plug to complete the electrical connection.
Positive contact is a rigid part, its shape is cylindrical (round pin), square column (square pin) or flat (insert). Positive contact parts are generally made of brass, phosphor bronze.
The negative contact is the jack, is the key parts of the contact pair, it relies on the elastic structure in the insertion with the pin when the elastic deformation and elastic force and the positive contact to form a close contact to complete the connection. Jack structure of many kinds, there are cylindrical (split groove, indentation), tuning fork type, cantilever beam type (longitudinal slotted), folded type (longitudinal slotted, 9 characters), box-shaped (square jack) and hyperbolic wire spring jack.
2, insulator Insulator is also often called the base (base) or mounting plate (insert), its role is to make contact parts according to the required bit and spacing arrangement, and to ensure that the insulation properties between the contact parts and between the contact parts and the shell. Good insulation resistance, voltage resistance performance and easy processing is the choice of insulation materials processed into the basic requirements of the insulator.
3, the shell, also known as the shell (shell), is the outer cover of the connector, which provides mechanical protection for the insulated mounting plate and pins inside, and provides alignment when the plug and socket are inserted, and thus the connector is fixed to the equipment.
4, accessories Accessories are divided into structural accessories and mounting accessories. Structural accessories such as snap rings, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, seals, gaskets, etc.. Installation accessories such as screws, nuts, screws, spring rings, etc.. Most of the accessories have standard parts and common parts.
Contact pressure in the connector is an important indicator, which directly affects the size of the contact resistance and the amount of wear on the contact pair. In most structures, direct measurement of contact pressure is quite difficult.
The connector is an electromechanical component that connects electrical circuits. Therefore, the electrical parameters of the connector itself is the first thing to consider when choosing a connector.
An electrical connector, also known as a circuit connector, is a conductor device that bridges two conductors on a circuit so that current or signals can flow from one conductor to the other. An electronic connector is a motor system that provides a separable interface to connect two sub-electronic systems. Simply put
Connector is a part of our electronic engineers and technicians often contact. Its role is very simple: in the circuit is blocked or isolated between the circuit, bridging the communication, so that the current flow, so that the circuit to achieve the intended function.
A standard is a unified provision made for repetitive things and concepts. It is based on the comprehensive results of science, technology and practical experience, approved by consensus of the parties concerned and published in a specific form by the competent authority as a guideline and basis for common compliance.
As connectors become increasingly diverse and new structures and applications emerge, attempts to solve the classification and naming problem with a fixed model have become difficult to accommodate. Nevertheless, some basic classifications are still valid.
