In What are the structures of the SIM card holder connector?

With the continuous development of mobile phone and other electronic products in recent years, the market demand has gradually expanded. Do you know the composition of mobile phone socket connectors? Fbele electronics shares with you the structure of the SIM card holder connector?

Insulator insulator is also often called base or insert. Its function is to place the touch pieces according to the required orientation and distance, and ensure the insulation function between the touch pieces and between the touch pieces and the shell. Excellent insulation resistance, voltage resistance and processability are the basic requirements for selecting insulation materials to be processed into insulators.

Contacts are the central part of the adapter to complete the electrical connection function. Generally, a touch pair is composed of a male touch piece and a female touch piece, which are electrically connected after the insertion of the female and male touch pieces. The male touch part is a rigid part, and its shape is cylindrical (round pin), square cylinder (square pin) or flat (insert). The male touch pieces are generally made of brass and phosphor bronze. The female touch piece is the socket, which is the key part of the touch pair. It relies on the elastic structure to produce elastic deformation when it is inserted with the pin, resulting in the elastic force. It forms a tight touch with the male touch piece and completes the connection. There are many types of jacks, including cylindrical (slotted, necked), tuning fork, cantilever (longitudinally slotted), folded (longitudinally slotted, 9-shaped), box (square) and hyperboloid spring jacks.

The shell, also known as the shell, is the outer cover of the. It provides mechanical maintenance for the built-in insulating device board and pins, and provides the alignment when the plug and socket are inserted, so as to fix the adapter to the equipment.

Accessories are divided into structural accessories and device accessories. Structural accessories such as snap ring, locating key, locating pin, guide pin, connecting ring, clamp, sealing ring, sealing gasket, etc. Device accessories such as screws, nuts, screws, spring rings, etc. Most of the accessories are standard parts and general parts.
