Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of binding post that can realize that the short circuit open circuit switches.
Binding post described in the utility model comprises plug and socket, and described plug is provided with at least one automatic short-circuit mechanism, is used for when plug and socket separates the horizontal relative contact short circuit of plug side; Described socket is provided with insulation board, is used for disconnecting when plug and socket plugs together automatic short-circuit mechanism.On plug, be provided with automatic short-circuit mechanism, can make that will be connected with two of electric equipment automatically in plug and the socket time of releasing connects and touch the part short circuit, prevents to produce electric spark; Can when plug and socket plugs together, disconnect being provided with insulation board on the socket, this moment plug and socket the contact contact, form two loops independently, do not influence being connected of electric equipment and tester.
Further, described automatic short-circuit mechanism comprises that two components are located at the current feed sub-assembly on the laterally relative contact, this current feed sub-assembly is mainly formed by L shaped brace, short-circuit spring leaf and line spring aperture member riveted, wherein the top of L shaped brace contacts with lead-in wire, bottom and short-circuit spring leaf stiff end are fitted, the free end contact of the short-circuit spring leaf of two opposite sides.The lead of electric equipment is connected with short-circuit spring leaf by L shaped brace, and when plug and socket separated, two short-circuit spring leafs formed the short circuit loop with two contact short circuits under the elastic force effect.In the binding post assembling process, can the quantity and the installation site of short circuit mechanism specifically be set according to the needs of reality use.
Further, be respectively equipped with an insulation board between the horizontal relative contact of described socket, the corresponding a pair of short-circuit spring leaf of insulation board, when plug and socket plugged together, insulation board separated two short-circuit spring leafs, and short circuit this moment mechanism is an open-circuit condition.
Preferably, described insulation board is worker's shape plate.Its rigidity can be improved in the I-shaped cross-section of insulation board, and the middle part of insulation board is thinner, can reduce the decrement to short-circuit spring leaf, and the both sides of broad can increase the creepage distance between two short-circuit spring leafs, improves dielectric strength.
In the said apparatus, described plug adopts the cam structure anchor leg.L shaped brace top is inserted between cam and the cam holder, and when line pressing bolt screwed, cam swayed and will place the lead-in wire between cam and the L shaped brace to compress, and can realize being electrically connected, and adopted this structure can avoid lead-in wire to expose, and guaranteed Electrical Safety.
Further, the line ball position of described cam is provided with anti-slop serrations, prevents the slippage that goes between, and has improved the fastness of line.
The utility model is provided with automatic short-circuit mechanism in plug, can realize the short circuit between plug side contact when plugs and sockets separates, and prevents that the back electromotive force in the electric equipment from damaging electric component, has prolonged the useful life of electric component.
