2. connecing switch ground connector described in claim 1, which is characterized in that switch ground connector seal washer and electricity The connection of gas equipment shell, reaches waterproof purpose.

Technical field

The present invention relates to large power supply circuits in relation to ground connection or the earth-free technology beaten in terms of high pressure.

Background technique

The power supply of high power driver, it is sometimes desirable to carry out beating high-potting, wherein needing to be grounded power circuit Or earth-free test, at present still without find this respect technique device.

Summary of the invention

High-potting is beaten to solve aforementioned high power power, the present invention provides a kind of switch ground connector, which opens Closing connector is that an insulating sleeve is socketed in a circular casing, and insulating sleeve center is socketed a metal probe, circular casing one End outer circle has screw thread, and circular casing middle section outer circle has the nut of evagination, and nut is linked together with circular casing, circular casing one The insulating sleeve in port is held, to contract a distance, recess is formed, has a spring pocket on thimble in recess, spring is stretched After circular casing port out, an external end socket nut and circular casing are spirally connected, metal thimble and circular casing are electrically connected, and are screwed out External end socket nut, disconnects circular casing and metal thimble is electrically connected.

The switch ground connector seal washer is connect with electrical equipment casing, reaches waterproof purpose.

It is an advantage of the invention that high power power is grounded linking probe, precession end socket nut is power ground, is screwed out End socket nut be power supply disconnect ground connection, it is very convenient ground connection with it is earth-free, securely and reliably.And it is alternatively arranged as water proof switch and makes With.

Specific embodiment

It please refers to shown in attached drawing, switch ground connector is that an insulating sleeve 4, insulation sleeve are socketed in a circular casing 1 4 center of pipe is socketed a metal thimble 5, and 1 one end outer circle of circular casing has screw thread 2, and 1 middle section outer circle of circular casing has the six of evagination Angle nut 3, nut 3 are linked together with circular casing 1, the insulating sleeve 4 in 1 one end port of circular casing, to one section of contract Distance forms recess 6, has 10 sets of a spring on thimble 5 in recess 6, and spring stretches out 1 port of circular casing, an external end socket After nut 7 and circular casing 1 are spirally connected, metal thimble 5 and circular casing 1 are electrically connected, i.e., thimble 5 and casing are electrically connected, by It is connect in thimble 5 with power ground line, is that power ground line connect ground connection with casing in this way.External end socket nut 7 is screwed out, is broken Opened round casing 1 and metal thimble 5 are electrically connected.

The switch ground connector is connect with seal washer 8 with electrical equipment casing 9, reaches waterproof purpose.

When the present invention and casing 9 are installed, first by 9 aperture of casing, will have out of casing 9 one end through hole of external screw thread 2 to Outer stretching, outside nut 11 and casing 9 are spirally connected fixation, are spirally connected after encrypting seal washer 8 with end socket nut 7.
