Board-to-board connector structure

The basic structural components of the board-to-board connector are as follows: contacts, insulators, housings, accessories

Contacts are the core parts of the connector that complete the electrical connection. The contact pair is generally composed of a male contact and a female contact, and the electrical connection is completed by the insertion of the female and male contacts.

The positive contact is cylindrical (round pin), square column (square pin) or flat (tab) and is a rigid part. Positive contacts are typically made of brass or phosphor bronze.

The contact piece is a jack, which is a key part of the contact pair. It relies on the elastic structure to elastically deform when it is inserted into the pin, and generates an elastic force to form a close contact with the male contact member to complete the connection.

There are many types of jacks, such as cylindrical (groove, neck), tuning fork type, cantilever beam type (longitudinal slotted), folded type (longitudinally slotted, 9-shaped), box-shaped (square jack) And a double-curved wire spring jack.

Insulators, also commonly referred to as pedestals or mounting plates, function to align the contacts at the desired location and spacing and to ensure insulation between the contacts and between the contacts and the casing. Good insulation resistance, withstand voltage performance and ease of processing are the basic requirements for the selection of insulating materials into insulators.

The housing, also called the housing, is a cover for the board-to-board connector that provides mechanical protection for the built-in insulated mounting plate and pins, and provides alignment when the plug and socket are mated, thereby securing the board-to-board connector to On the device.

Attachment accessories are divided into structural accessories and mounting accessories. Structural accessories such as collars, positioning keys, locating pins, guide pins, coupling rings, cable clamps, seals, gaskets, etc. Install accessories such as screws, nuts, screws, coils, etc. The accessories are mostly standard and general.
