Sumitomo 4 way black waterproof Car Cable Connector 6195-0018
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.
Third, insulator, which is also referred to as base or insert of automobile connector; its function is to arrange contacts according to required position and distance, and ensure the insulating property between contacts and that between contacts and shell. Good insulation resistance, voltage resistance and workability are the basic requirements for insulation materials to be processed into insulators.
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.
Before the permutation of wiring harness, its drawing ought to be laid out first, the wiring harness drawing is different from circuit principle diagram
The later reflects relations between various electrical parts, not to reflect how the parts are connected to each other, and is not influenced by size, shape of electrical components and their distance from each other
While wiring harness drawing must take the above factors into consideration, and reflect how electrical parts are connected to each other
After cable harness board is made by technicians in wiring harness factory according to wiring harness drawing, workers start transversal and winding displacement according to provisions of cable board.
