The utility model mainly comprises two portions of a grounding device and an insulating action bar, and the grounding device is fixedly connected with the insulating action bar. The utility model has simple, compact and rational structure, and the operating crew does not need to contact the cable component in the process of grounding, ensuring the personal safety of the operating crew.
Description
Technical field
The utility model relates to a kind of earthing tool of cable of cable branch box, is used for directly not contacting under the situation of cable branch box cable in the scope of activities of safety, finishes ground connection work, belongs to security protection
Technical field.
Background technology
At present, domestic a plurality of producers have made elbow type earth cable joint at the single, double logical casing joint constitution equipment of box change and loop-network switch cabinet, can finish last ground connection work by this cable joint.But regrettably, have not yet to see special-purpose earthing tool,, exist great potential safety hazard so bring difficulty to the cable grounding operation of cable branch box power failure work.
Technology contents
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple, compact and reasonable for structure; In the ground connection process, operating personnel do not need directly to contact cable assembly, just can realize the instrument to 10KV cable branch box cable grounding.
Main solution of the present utility model is achieved in that
The utility model mainly is made up of earthing device and insulating bar two parts, and earthing device and insulating bar are fastenedly connected.
Earthing device mainly is made up of the body 7 that is threaded, base 10, spring 8, spiral shell spare 13, intermediate plate 14 and pad 15, be threaded body 7 of employing is fastening with base 10, spring 8 is installed in and is threaded between body 7 and the base 10, spiral shell spare 13 fuses with base 10, and intermediate plate 14, pad 15 are placed on 13 of base 10 and spiral shell spares.
Insulating bar mainly is made up of special-shaped sleeve 1, insulating epoxy pipe 5, magnet steel 3, magnet steel seat 2 and lever 6, special-shaped sleeve 1 is connected with insulating epoxy pipe 5, magnet steel 3 is installed in special-shaped sleeve 1, and magnet steel 3 is placed on the magnet steel seat 2, and lever 6 is installed in insulating epoxy pipe 5 bottoms.
Compared with the prior art the utility model has the following advantages:

Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of special-shaped sleeve 1, magnet steel seat 2, magnet steel 3, fixed screw 4,9, insulating epoxy pipe 5, lever 6, the body 7 that is threaded, spring 8, base 10, bearing pin 11, lateral pin 12, spiral shell spare 13, intermediate plate 14, pad 15 etc.
The utility model mainly is made up of earthing device and insulating bar two parts, and earthing device and insulating bar are fastenedly connected.
The utility model earthing device mainly is made up of the body 7 that is threaded, base 10, spring 8, spiral shell spare 13, intermediate plate 14 and pad 15.Employing is threaded, and body 7 passes through screw 9 and base 10 is fastening, spring 8 is installed in and is threaded between body 7 and the base 10, and spiral shell spare 13 fuses by bearing pin 11 and base 10, and lateral pin 12 is contained on the spiral shell spare 13, intermediate plate 14, pad 15 are placed on 13 of base 10 and spiral shell spares, are convenient to the dead earth line and use.
The utility model insulating bar mainly is made up of special-shaped sleeve 1, insulating epoxy pipe 5, magnet steel 3, magnet steel seat 2 and lever 6.Special-shaped sleeve 1 is connected with insulating epoxy pipe 5 by fixed screw 4, and magnet steel 3, magnet steel seat 2 are installed in special-shaped sleeve 1, and magnet steel 3 is placed on the magnet steel seat 2, and rubber lever 6 is installed in insulating epoxy pipe 5 bottoms.
The utility model operating procedure is as follows: 1, connect earth terminal earlier, after connect conductor end, earthing device and insulating bar hold by magnetic, hook stick rotation, but lateral pin 12 corresponding bayonet sockets can block and the driven rotary earthing device; 2, the body 7 (its thread standard is decided according to the size of the existing most cable branch box double threaded screws that use) that will be threaded is enclosed within on the cable branch box double threaded screw, and rotating insulated action bars is tightened it, and promptly the earthing device front end connects.(general cable branch box double threaded screw has only two kinds of sizes, makes as required) 3, push away insulating bar and make spring shrink rotation one angle, make bearing pin 11 deviate from base 10 notches, earth connection rear end screw thread begins stressed.Rotating insulated action bars makes intermediate plate 14, pad 15 and the body 7 that is threaded closely contacts with spiral shell spare 13 screw sockets, and promptly install firmly the earthing device rear end; 4, transfer to the insulating bar repetitive operation that three-phase is all connected, the earth connection installing finishes.
