Abstract
The utility model discloses the easy crocodile wire clamp of terminal block, it is made up of upper and lower two symmetrically arranged wire clip bodies, insulated handle is equipped with respectively in one end of upper and lower two wire clip bodies, crocodile degree of lip-rounding jaws is formed after the other end is closed, the middle part of upper and lower two wire clip bodies is connected by a coupling shaft (4), the upper pocketed springs (1) of coupling shaft (4), two of spring (1) stretch out termination and push up respectively and press lower two wire clip bodies and make crocodile degree of lip-rounding jaws be in normally off, and upper wire clip body welds 7 font copper rods (2) outside jaws end.Use the utility model terminal block easy crocodile wire clamp, can increase work efficiency, reduce the electric shock risk that operating personnel exist at work, and the safety coefficient of operating personnel and work efficiency are improved greatly.
Description
Technical field
The utility model relates to a kind of electric wire and controls apparatus, the specifically easy crocodile wire clamp of a kind of terminal block.
Background technology
When high-voltage switch gear carries out testing mechanical characteristic and low-voltage test, need to export from high-voltage switch mechanical characteristic tester to control power supply to switch control circuit, the power supply input of switch control circuit is namely used as by the tester of the mechanical property of high-voltage switch gear, by the input difference of tester, the performance of high-voltage switch gear is tested, the principle of its work is by analog switch electric operating process, gather that switch divides simultaneously, closing time, not the time same period, low point, the data such as low conjunction operation voltage value to be to judge the state of switch.The terminal block kind that switch control circuit uses is " rail cartridge screw connecting terminal block ", there were two kinds of method Access Control power supplys during test in the past, one is adopt shorting stub to draw again with the access of crocodile wire clamp from terminal block, two is assist fixing with p-wire inserted terminals row screw hole place testing crew, but the drawback that these two kinds of methods all exist large, the consuming time length of workload, easily get an electric shock.If adopt two kinds of methods in the process of high-voltage switch gear being carried out to characteristic test, the workload of so high-voltage switch gear being carried out to characteristic test will be huge, no matter be adopt shorting stub to receive on terminal or by being assisted to fix by personnel in the hole of p-wire inserted terminals all to there is certain risk, and operating process is also comparatively loaded down with trivial details, consuming time very long.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of easy crocodile wire clamp of terminal block that is safe and reliable, that increase work efficiency, reduce the electric shock risk that exists at work of operating personnel, and the safety coefficient of operating personnel and work efficiency are improved greatly.
The utility model solves the problems of the technologies described above with following technical scheme:
The utility model terminal block easy crocodile wire clamp is made up of upper and lower two symmetrically arranged wire clip bodies, insulated handle is equipped with respectively in one end of upper and lower two wire clip bodies, crocodile degree of lip-rounding jaws is formed after the other end is closed, the middle part of upper and lower two wire clip bodies is connected by a coupling shaft 4, pocketed springs 1 on coupling shaft 4, two of spring 1 stretch out termination and push up respectively and press lower two wire clip bodies and make crocodile degree of lip-rounding jaws be in normally off, and upper wire clip body welds 7 font copper rods outside jaws end.
Adopt the easy crocodile wire clamp of the utility model terminal block by the power lead of high pressure characteristics tester access switch control circuit, the drawback existing for traditional terminal connections two kinds of modes can be avoided, first consider that the crocodile wire clamp after due to improvement need not adopt shorting stub again or wire is inserted into the mode be fixed terminal hole from secure context, doing so avoids the danger that may occur to get an electric shock; Secondly in the process of carrying out testing mechanical characteristic, adopt the mode of connection of the crocodile wire clamp after improving only to need the connection terminal of correspondence to be suspended to the characteristic test that corresponding copper rod just can complete for high-voltage switch gear, the mode of connection of the process of whole test is very convenient and simple, and this just substantially increases the efficiency of high-voltage switch gear being carried out to efficiency test.
Accompanying drawing explanation
Fig. 1 is the structural representation of the easy crocodile wire clamp of the utility model terminal block.
Fig. 2 is the structural representation of spring 1 in Fig. 1.
Fig. 3 is the schematic diagram that in Fig. 1, coupling shaft 4 is connected with spring 1.
In figure: 1---spring, 2---7 font copper rods, 3---upper wire clip body, 4---coupling shaft, 5---insulated handle, 6---crocodile degree of lip-rounding jaws, 7---drop wire clip body.
Embodiment
Be described further below in conjunction with the structure of accompanying drawing to the easy crocodile wire clamp of the utility model terminal block.
As depicted in figs. 1 and 2, the utility model terminal block easy crocodile wire clamp is connected and composed by coupling shaft 4 by two symmetrical upper wire clip bodies 3 with electric conductivity and drop wire clip body 7, coupling shaft 4 passes the middle part of upper wire clip body 3 and drop wire clip body 7, one end of upper wire clip body 3 and drop wire clip body 7 is respectively equipped with insulated handle 5, and the other end is in involutory rear formation crocodile degree of lip-rounding jaws 6; Coupling shaft 4 is provided with spring 1, the two ends of spring 1 are pushed up respectively and are pressed lower two wire clip bodies and make crocodile degree of lip-rounding jaws 6 be in normally off, and upper wire clip body adopts the mode of multi-point welding to weld 7 font copper rods 7 in the outside of jaws 6 one end.
During use, hold insulated handle 5 to pressure, upper wire clip body 3 and drop wire clip body 7 are rotated around coupling shaft 4, make crocodile degree of lip-rounding jaws 6 realize opening or closed action.During wiring, the control power lead of high pressure characteristics tester is inserted in crocodile clip wiring hole, inserted by 7 font copper rods 7 in the screw hole of switch " rail cartridge screw connecting terminal block " corresponding circuit and connect, and then crocodile degree of lip-rounding jaws 6 is clamped " rail cartridge screw connecting terminal block " fix, just can complete the performance test wiring for high-voltage switch gear, the mode of connection of the process of whole test is very convenient and simple, and operating efficiency is high, and handling safety is reliable.
