Automotive connectors is our electronic engineers are often a part of the contact. Its role is very simple: in a circuit is blocked or isolation circuit between, can help build a bridge of communication, so that the current circulation, make the circuit can realize the function of reservation. Auto connectors form and structure is protean, its mainly consists of four basic structure components, respectively is: contact element, shell (depending on the species), insulation, attachment.
A, contact element, is the core of automotive connectors complete electrical connection parts. Generally consists of positive and negative contact piece of contact, through Yin and Yang contact is inserted and complete electrical connection.
Positive contact pieces for the rigid parts, its shape is cylindrical pin (circle), square shaped pin (party) or flat shape (insert). Positive contact is generally made from brass and phosphor bronze. Negative is jack, it is the key contact for parts, it depends on the elastic structure in elastic deformation with pin inserted timeliness and produce elastic force and positive contact form close contact, complete the connection. Jack has a variety of structures, a cylinder type (split groove, reducing), a tuning fork type, cantilever type (longitudinal slot), folding type (longitudinal slot, 9 glyph), box (square socket) and hyperboloid line spring socket etc.
Second, shell, also known as the shell (shell), is the outer garment of car connector, it is built-in insulation installation plate and pin to provide mechanical protection, and provide the plug and socket inserted right alignment, then to fix the connector on the device.
Three, insulator, insulator is often called the car connector base (base) or mounting plate (insert), its role is to make contact, in accordance with the need to arrange the location and spacing, and ensure the contact and contact between the parts between the shell and insulation performance. Good insulation resistance, voltage resistance and easy workability is to choose the insulating materials processed into the basic requirements of insulator.
Four, attachments, accessories and installation accessories attachment points structure. Accessories such as retainer ring structure, positioning keys, pins, guide pin, connecting ring, cable clamp, seals, gaskets, etc. Installation accessories such as screw, nut, screw, spring coil, etc. Accessories have a standard and interchangeable parts.
It is the four basic structure component that car connector can act as a bridge, and stable operation.
