Description
Technical field
The present invention relates to a kind of electric power overhaul instrument, be specifically related to a kind of earthing clamp be applicable in switch cubicle.
Background technology
At present, when electric power apparatus examination, hanging earth connection is to guarantee one of safe measure.Existing ground clamp can only hang bus or arrange online in the situation of spacing and use, narrow space in switch cubicle, the Pin arrangement direction differs, while needing to hang ground wire on the lead-in wire (or bus bar) of arranging at fixed contact and/or the lateral balance of disconnecting link, conventional earthing clamp is because the jaws direction is vertical with insulating bar, so can not hang, thereby the technical measures that guarantee staff's safety can not effectively be implemented.
For above-mentioned defect, need the earthing clamp of a kind of quick effective grounding of lead-in wire of can be conveniently the switch fixed contact in switch cubicle and/or lateral balance being arranged of invention, with the staff's that guarantees associative operation life safety.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of simple in structure, cost is lower and the convenient lead-in wire (or bus bar) of in switch cubicle, switch fixed contact and/or lateral balance the being arranged earthing clamp of effective grounding fast.
The present invention adopts following technical scheme:
The present invention includes insulating bar, be fixed on the wire clamp main body on insulating bar and be arranged on the moving contact on the wire clamp main body; Described wire clamp main body is U-shaped, it comprises crossbeam, is arranged on the fixed contact of crossbeam one end and the reference column that is arranged on the crossbeam other end, be provided with binding post on described reference column, described insulating bar is arranged on the crossbeam outside, makes the opening direction of described wire clamp main body upward; Be fixedly installed backstay on described moving contact, described backstay is nested with on reference column by the location hole be arranged on reference column, on described backstay, is equipped with stage clip, and by stage clip make moving contact and fixed contact press with together with.
As of the present invention further perfect, the upper end of the one side of described moving contact and fixed contact joint is chamfering or rounding.
As of the present invention further perfect, described insulating bar is arranged on a side of close reference column on crossbeam.
As of the present invention further perfect, described backstay is two, and corresponding location hole and stage clip are two.
As of the present invention further perfect, the inboard of described fixed contact is provided with arc groove.
As of the present invention further perfect, the one side of described moving contact and fixed contact joint is provided with anti-slip veins.
Good effect of the present invention is as follows:
Use when of the present invention, because the opening direction of wire clamp is consistent with the direction of insulating bar, so during the lead-in wire (or bus bar) of arranging with the switch fixed contact in wire clamp folder switch cubicle and/or lateral balance, insulating bar can not hinder operation, so just facilitated earthing clamp to use in the switch cubicle of narrow space, especially insulating bar is arranged on to a side of close reference column on crossbeam, when many rows of the inherent depth direction of switch cubicle go between while needing simultaneously earth connection, owing to insulating bar and moving contact and the contacted position of fixed contact staggering, so just can make insulating bar avoid front-seat lead-in wire (or bus bar) and clamp smoothly rear row's lead-in wire, chamfering or fillet are arranged to in the moving contact upper end, and convenient bus, lead-in wire or the switch fixed contact etc. clamped, save time in use, increases work efficiency.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention;
The structural representation that accompanying drawing 2 separates with fixed contact for moving contact of the present invention;
Accompanying drawing 3 is provided with the location hole structural representation on reference column of the present invention.
In the accompanying drawings: 1 insulating bar, 2 crossbeams, 3 fixed contacts, 3-1 arc groove, 4 moving contacts, 5 backstays, 6 stage clips, 7 binding posts, 8 reference columns, 8-1 location hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
A kind of earthing clamp be applicable in switch cubicle as shown in accompanying drawing 1-3, it comprises insulating bar 1, is fixed on the wire clamp main body on insulating bar 1 and is arranged on the moving contact 4 on the wire clamp main body, the reference column 8 that described wire clamp main body comprises crossbeam 2, is arranged on the fixed contact 3 of crossbeam 2 one ends and is arranged on crossbeam 2 other ends, be provided with the binding post 7 that connects ground wire on described reference column 8, binding post 7 is for being screwed in the bolt of reference column 8, facilitate the connection of ground wire, before use, ground wire need to be connected on reference column 8 by binding post 7; As shown in Figure 1, it is U-shaped that the wire clamp main body totally is, its opening direction upward, consistent with the direction at insulating bar 1 place, so during the lead-in wire of arranging with the switch fixed contact in wire clamp folder switch cubicle and/or lateral balance, insulating bar 1 can not hinder operation, has so just facilitated earthing clamp to use in the switch cubicle of narrow space.
As shown in Figure 1, described insulating bar 1 is arranged on a side of close reference column 8 on crossbeam 2, when many rows of the inherent depth direction of switch cubicle go between while needing simultaneously earth connection, owing to staggering in the position of contacted of moving contact 4 and fixed contact 3 and insulating bar 1, so just can make insulating bar 1 avoid front-seat lead-in wire and clamp smoothly rear row's lead-in wire.
As shown in Figure 2, described moving contact 4 is chamfering or fillet with the upper end of the one side of fixed contact 3 joints, convenient bus, lead-in wire or the switch fixed contact etc. clamped during use, save time, increase work efficiency, in addition, the inboard upper angles of corresponding fixed contact 3 are set to chamfering or fillet also can reach same effect; Be fixedly installed two backstays 5 on described moving contact 4, described backstay 5 is nested with on reference column 8 by the location hole 8-1 be arranged on reference column 8, and can in location hole 8-1, slide, be equipped with stage clip 6 on described backstay 5, under the effect of stage clip 6, moving contact 4 and fixed contact 3 press with together with; With the fixing moving contact 4 of two backstays 5, during use, moving contact 4 is more stable, can not teetertotter, easy to use.
As shown in Figure 1, moving contact 4 and the contacted one side of fixed contact 3 are provided with to anti-slip veins, be specially corrugated projection or zigzag projection, can make wire clamp effectively contact with lead-in wire or switch fixed contact, the clamping better effects if, be difficult for slippage, and can prevent that loose contact is accidents caused, the one side of corresponding fixed contact 3 is arranged to corrugated or the zigzag projection also can have identical effect.The inboard of described fixed contact 3 is provided with arc groove 3-1, by the bare wire earth connection time, can be by cross section circular bare wire holding in arc groove 3-1, be difficult for slippage.
The above execution mode is only the preferred embodiments of the present invention, and is not the exhaustive of the feasible enforcement of the present invention.For persons skilled in the art, any apparent change of under the prerequisite that does not deviate from the principle of the invention and spirit, it having been done, within all should being contemplated as falling with claim protection range of the present invention.
