The basic structure of the female connector is introduced How much do you know about the performance characteristics of the row of pins and row of female connectors?

How many performance characteristics of the row of pins and needles you know? The main performance includes the following aspects. 1, ease of operation, the mechanical strength of the row of pins is also a very important factor. The connector is usually the interface between the PCB motherboard and the external components of communication, the row of pins and rows of mother is very strong, sometimes may encounter considerable external forces also intact. 2, through-hole technology assembled components in terms of reliability is much higher than the corresponding SMT components. Whether it is a strong pull, extrusion or thermal shock, it can withstand, and not easy to detach from the PCB. 3, used in the industrial field field wiring of the row of pins row of mother processing is usually a high-power components, can meet the different transmission of high-voltage and high-current needs. 4, these advantages with the reduction of the component adhesion force in the PCB weakened. The characteristics of the row of pins and rows of mother components is in the compact design, and easy to mount, and through-hole row of pins in the size and assembly form there is a clear difference. 5, with the resistance to electric strength, refers to the row of pins between the contact between the contact parts, or between the contact parts and the shell can withstand the ability of the rated test voltage. 6, the general row of pins and rows of mother can be adapted to the attenuation caused by electromagnetic interference, as well as the ability to electromagnetic interference shielding and so on. 7, the contact resistance of pins and row of pins is usually a high power component to meet different needs of transmission of high voltages and currents. 7, pin contact resistance, contact resistance should be small, can be as small as tens of milliohms.

Female connector is a widely used in electronics, electrical appliances, instrumentation in the general-purpose connecting devices, mainly to play the role of current or signal transmission. Usually used in conjunction with the row of pins, constitute a board-to-board connection. It has four basic structural components: a contact. Is the core parts of the female connector to complete the electrical connection function. Generally by the positive contact and negative contact components composed of contact pairs, through the negative and positive contact parts of the insertion and completion of the electrical connection. Second, the shell. Also known as the shell (shell), is the outer cover of the female connector, it is mounted on the insulated mounting plate and pins to provide mechanical protection, and to provide plugs and sockets when the alignment of the plug and socket, and then the female connector is fixed to the equipment. Third, the insulator. Insulator is also often referred to as female connector base (base) or mounting plate (insert), its role is to make contact with the required location and spacing, and to ensure that the contacts and contacts between the shell and the insulation properties. Good insulation resistance, voltage resistance and easy processing is the choice of insulating materials processed into the basic requirements of the insulator. Fourth, accessories. Annexes are divided into structural accessories and installation accessories. Structural 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.
