What are the basic functional structural components of a terminal block connector?

First, the basic function of the terminal connector structural components are: 1. insulator insulator (usually also known as the base or mounting plate) is used to arrange the contacts in the desired location and spacing, and to ensure that the insulation between the contacts and between the contacts and the shell. Good insulation resistance, voltage resistance, and ease of processing are the basic requirements for selecting insulating materials to be processed into insulators.2. The shell, also known as the housing, is the shell of a terminal connector that secures the connector to the device by providing mechanical protection for the insulating mounting plate and the pins mounted within it, and by providing alignment of the plug and receptacle during insertion.3. The touch member is the terminal connector's The touch piece is the core part of the terminal connector to complete the electrical connection function. uk terminals are suitable for a large number of wire interconnections, in the power industry there is a special terminal row, terminal box, above all the terminals, single layer, double layer, current, voltage, ordinary, can be broken and so on. A certain crimping area is to ensure reliable contact, as well as to ensure that enough current can pass. Terminals with the increasing degree of industrial automation and industrial control requirements more and more stringent,, the amount of terminals gradually rise. With the development of the electronics industry, the use of terminals more and more, and more and more types. Terminal block in order to facilitate the connection of wires and applications, it is actually a section of metal sealed inside the insulating plastic, both ends have holes can be inserted into the wire, there are screws for fastening or loosening, such as two wires, sometimes need to be connected, sometimes need to be disconnected, this time you can use the terminals to connect them, and can be disconnected at any time, without having to weld them up or entangled in the same, it's very Convenient. Contact pairs are generally composed of positive and negative contacts, by inserting negative and positive contacts to complete the electrical connection. Positive contacts are rigid parts made of cylindrical (round pins), square cylinders (square pins) or flat shapes (round inserts). Positive contacts are typically made of brass and phosphor bronze. The negative contact is the jack, which is the key part of the contact pair. It depends on the elastic structure, elastic deformation with the pin insert, elastic force and close contact with the positive contact to complete the connection. There are various types of jack structures, including cylindrical (split slots, constriction ports), sound fork, cantilever beam (longitudinal slots), overlap (vertical slots, Fig. 9), box (square jacks), and double curved wire spring jacks.
