PA66 grey SUMITOMO auto 6 pin waterproof wire harness connector 6189-0766
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.
Second, case, also known as shell, is the enclose of automotive connector; it provides protection for built-in insulation board and contact pin, and makes plug and socket fit when inserted, and then have the connector fixed on equipment.
Product Description
|
Automotive connectors must reach the specifications of USCAR—20, which is the performance standard for automotive electrical connector system; it specifies that in the entire life span of a automotive connector, contact surface of electrical connector must be reliable all the time, including the following several factors.
It must be the same as the connector used by high-spped and long-distance communication computer, the automotive connector must be able to work efficiently under terrible conditions.
Four major basic structural components of automotive connecter
First, contact, which is the core component for automotive connector to accomplish electric connecting function. It normally consists of a positive contact and a negative one, and the two form contact pair; electric connecting will be accomplished via plugging of positive and negative contacts.
At present, global automotive connectors take up around 15% that of connector industry, and they are likely to take up even larger proportion in the future due to the driving of electric automotive products.
