Locking connectors are designed so that different voltages and current ratings can not be accidentally intermated. [33] Many specific types exist; only a few are listed below. Other types include special purpose connectors for boats, 400 Hz circuits such as used for aircraft, and direct-current applications.
Cigarette lighter receptacles are in widespread use in many highway vehicles and some boats. Portable cigarette lighter receptacles attached to cables and alligator clips for connection directly to car batteries are available for temporary use. In newer vehicles, one or more USB connectors may also be provided. Plus in newer cars, the power ...
75 Ω for video signal (SDI and CoaXPress) on, for example, RG59 and RG6. 50 Ω for data link, like Ethernet on RG58. 93 Ω on RG62. 50 Ω (white/bottom row) and 75 Ω C connectors (red/top row) C connector (Concelman connector) General Radio 874 connectors GR connector (General Radio connector) Mostly seen on the company's test equipment.
Flat 5-pin connector (Towing vehicle side) This contact is not as common, but is compatible with the 4-pin connector in the way that a towing vehicle with this connector can be connected to a trailer with the 4-pin flat plug. The extra connection is often used to block the surge brakes when reversing with the trailer. #
SAE J1772, also known as a J plug or Type 1 connector after its international standard, IEC 62196 Type 1, is a North American standard for electrical connectors for electric vehicles maintained by SAE International under the formal title "SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler".
The connector is circular, with the male connector having two pins placed symmetrically inside a circular shield, and the female connector having two receptacles surrounded by a circular groove to accept the male shield, in turn surrounded by a second circular shield which projects 6 mm (0.24 in) past the mating surface and encloses the male ...
It has an earthing pin and two flat current-carrying pins forming an inverted V-shape (120°). The flat pins for the 10 A version measure 6.25 by 1.55 mm (0.246 by 0.061 in) and 8.0 by 1.9 mm (0.315 by 0.075 in) for the 20 A version, and are set at 30° to the vertical at a nominal pitch of 7.92 mm (0.312 in).
Pin 1 is typically indicated on the body of the connector by a red or raised "V" mark. The corresponding wire in a ribbon cable is usually indicated by red coloration, a raised molded ridge, or markings printed onto the cable insulation. On the connector pin 2 is opposite pin 1, pin 3 is next to pin 1 along the length of the connector, and so on.
