Product Description

The positive contact is a rigid one, of which the shape is cylindrical (round contact pin), rectangular columnar (rectangular contact pin) or pancake (contact pin). And a positive is contact usually made from brass and phosphor bronze. The negative contact is the socket namely, an essential component for right connection. It impinges on positive contact by means of the elastic force produced in the elastic deformation when its elastic structure plugs with contact pin and connection is thus accomplished. There are various kinds of socket structures: cylindrical (slot, throat), tuning fork, over hanging beam (longitudinal slot), folded (longitudinal slot, shape pf number 9), box (square socket) and hyperbolic line spring socket, etc.

China's industry standard is only to specify main color, for example, black alone is for earth wire and red alone is for power line, which cannot be obscured.

The technology is developed aiming at the micromation trend of connectors, and it can be applied to micro connectors under 0.3 mm, belonging to new categories of MINI USB series. It can be used in multi-contact expanded card slot connectors, and can meet or even surpass the strict demand of multi-contact surface mount technology on contact coplanar, with high precision and low cost.
