Technical field
The present invention relates to a kind of three-phase and four-line with the disconnected jockey with connecting, belonging to power equipment field tests.
Background technology
In grid power equipment test process, need to use for arrangements of electric connection, in prior art, voltage output end for arrangements of electric connection is generally connected with equipment under test by screw, because power equipment test needs to cut off the electricity supply frequently, often disconnected by screw frequently or connect equipment under test, the test of grid power equipment needs disconnect three-phase four-wire power simultaneously simultaneously or connect simultaneously, can not accurately be realized with disconnected with connecting by screw.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of three-phase and four-line with the disconnected jockey with connecting.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of three-phase and four-line is with the disconnected jockey with connecting, comprise base plate, pressing plate and top board, connected by support bar between described base plate and top board, the bottom surface of described top board is provided with some cylinders, all cylinders are synchronous, the end of the expansion link of all cylinders is all fixed with the end face of pressing plate, the bottom surface of described pressing plate is provided with four projections, each projection is provided with conducting strip towards bottom, the end face of described base plate is provided with four recesses mated with projection, also conducting strip is provided with in described recess, conducting strip in its corresponding recess of conducting strip in described projection is relative, conducting strip in four projections and the cooperation of the conducting strip in four recesses realize grid power equipment three-phase four-wire power and are connected.
Described notched bottoms is also provided with power spring, and described power spring one end and notched bottoms are fixed, and the other end and conducting strip are fixed.
Described base plate is also provided with four through wires holes, in each through wires hole, is provided with the wire connecting power spring.
Described support bar is also provided with the control button in order to control cylinder motion.
Described cylinder number is three.
Each projection is arranged a through wires hole, in each through wires hole, be provided with the wire of the conducting strip connected in the projection of place.
The beneficial effect that the present invention reaches: the present invention in use, promote all projections by cylinder to move to recess simultaneously, conducting strip in projection is contacted with the conducting strip in recess, realize grid power equipment three-phase and four-line with connecting, when needs disconnect, cylinder shrinks, and the conducting strip in all projections is contacted with the conducting strip in recess and departs from simultaneously, achieves grid power equipment three-phase and four-line with disconnected; Namely achieve grid power equipment three-phase and four-line with disconnected with connecting, the present invention is simultaneously easy to use, simple to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of three-phase and four-line is with the disconnected jockey with connecting, comprise base plate 1, pressing plate 5 and top board 2, connected by support bar 3 between base plate 1 and top board 2, the bottom surface of top board 2 is provided with some cylinders 4, three cylinders 4 are set here, all cylinders 4 are synchronous, support bar 3 is also provided with the control button 11 moved in order to control cylinder 4, the end of the expansion link of all cylinders 4 is all fixed with the end face of pressing plate 5, the bottom surface of pressing plate 5 is provided with four projections 6, each protruding 6 are provided with conducting strip 7 towards bottom, one through wires hole 9 is set on each protruding 6, the wire of the conducting strip 7 connected in place projection 6 is provided with in through wires hole 9 on each protruding 6, the end face of base plate 1 is provided with four recesses 8 mated with projection 6, also conducting strip 7 is provided with in recess 8, conducting strip 7 in its corresponding recess of conducting strip 78 on protruding 6 is relative, conducting strip 7 in four projections 6 and the cooperation of the conducting strip 7 in four recesses 8 realize grid power equipment three-phase four-wire power and are connected.
