What are the structural components of a heavy-duty connector?

I. What are the structural components of the heavy-duty connector? Heavy-duty connector is used to manipulate the connector to transmit electronic signals or electrical devices, it is mainly contact parts, insulators, shells and accessories. 1. contact parts is the connector to complete the electrical neighboring function of the focal point of the parts. Ordinary by the positive contact and the negative contact components composed of contact pairs, by the negative and positive contact parts of the insertion and completion of the electrical neighboring connections. Positive contacts for rigid parts, commonly known as pins, its shape for the cylindrical (round pins), square cylindrical (square pins) or flat (inserts). Negative contact parts that jack, is the key parts of the contact pair, it relies on the elastic organization in the elastic deformation with the pin should occur when the elastic force occurs with the positive contact parts to form a discreet contact to complete the neighboring. 2. insulator is also often referred to as the base (base) or mounting plate (insert), it is the role of the contact parts according to the required location and spacing of the array, and to ensure that the contact parts and contact parts and the shell of the shell between the insulating function. Insulation function between contact parts and between contact parts and shell. Excellent insulation resistance, voltage function and easy processing is the choice of insulating materials processed into the insulator of the basic requirements. 3. shell, also known as shell (shell), is the connector of the outer shell, it is mounted for the insulation of the mounting plate and pins to provide mechanical protection, and supply plugs and sockets should be inserted when the alignment and the plug seat locking, and then connectors are fixed to the equipment. 4. attachments divided into organizational attachments and mounting Attachment. Organization accessories such as rings, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, seals, gaskets and so on. Installation accessories such as screws, nuts, screws, spring rings and so on. Most of the accessories are standard and general-purpose parts.
