Background technology
In electric experiment, often need electric equipment to be connected with tester through electric connector; When the electric equipment (like instrument transformer) that has solenoid is carried out measurement of electric parameter; Be prone to produce back electromotive force during often because of such electric equipment outage, cause electric component and electric equipment to be damaged.Therefore, for test, the safeguard protection of application facet, need between electric wiring, realize the switching of short circuit and open circuit.At present, also be provided with short-circuit structure on some electric connector, but these most complex structures, take up space greatly, can't satisfy the requirement of system's miniaturization, also, can't be popularized because manufacturing cost is high.
Summary of the invention
To the problems referred to above, it is a kind of simple in structure that the present invention provides, the short-circuit electric connector that is easy to realize.
The technical scheme that the present invention adopts is following: a kind of short-circuit electric connector; Comprise plug and socket; Plug is provided with two horizontal rows to relative line spring hole, and line spring hole is connected with line pressing bolt through brace respectively, socket be provided with two arrange with plug on the corresponding contact pin in line spring hole site; Be provided with short circuit mechanism between at least one pair of relative brace on the said plug, be used for when plug and socket separates brace short circuit two opposite sides; Said short circuit mechanism comprises spring and short-circuit block, and said spring one end and Plug base are affixed, and an end and short-circuit block are affixed, and short-circuit block contacts with the brace of both sides under the elastic force effect when plug and socket separates; Be provided with an insulation board between any two relative contact pins on the socket, Plug base is provided with the insulation that matches with the insulation board shape and inserts the road, is used for when plug and socket plugs together, breaking off short circuit mechanism.
The present invention is provided with short circuit mechanism on electric connector, can prevent electrical breakdown in the plug and socket time of releasing with plug side contact short circuit.The quantity of short circuit mechanism and position are provided with according to concrete connection device, can be that all opposing contact parts all are provided with, and also can select a part of position to be provided with.Simultaneously, plug together for ease of plug, socket or when separating, accomplish the rapid switching between the short circuit open circuit; Need between the contact pin of socket, insulation board to be set, insulation board inserts insulation and inserts the road, and spring is compressed; Short-circuit block is connected with terminal disconnection the in brace lateral part; Insulation board and contact pin have certain altitude poor, when plug and socket plugs together, guarantee contact pin with again short circuit mechanism is broken off after jack reliably contacts; When plug and socket separates, guarantee that before contact pin and jack break off horizontal contact reliably is connected in the plug.In addition, insulation board is inserted the road with insulation and is constituted isolation wells, has increased the creepage distance between live metal spare, has improved anti-electrical breakdown capability.
What in above-mentioned short circuit mechanism, adopt is that short-circuit block contacts with the both sides brace and accomplishes short circuit, and short-circuit block can be an arbitrary shape, but in order to reach best contact effect, and it is cylindrical that best mode is that said short-circuit block is set to.Simultaneously, said brace is provided with transverse part and vertical portion, and the transverse part end extends into an inclined-plane downwards, and inclined-plane and line spring axially bored line angle are 30-60 °, utilize the inclined-plane fully to contact with columniform short-circuit block.
Existing electric connector is when utilizing brace connecting line spring hole and line pressing bolt, and the brace that is adopted is terminal to be vertical plane, and line pressing bolt is positioned at a side, and operation is very inconvenient when crimping goes between like this.For overcoming this problem, the present invention slopes inwardly the vertical portion end of brace, becomes 30-60 ° of angle with line spring axially bored line, and is embedded with the line ball nut in the above, line pressing bolt is screwed in be used for the crimping lead-in wire.Like this, the line ball operating surface has a gradient, and the visual field is openr, operates easily.
