Abstract

The utility model discloses a grounding device of a distribution box. The grounding device comprises an iron bolt (2) and a copper binding post (4), wherein the bolt (2) is welded at the inner side of a distribution-box door (3), the binding post (4) is connected with a lead of a grounding copper bar in the distribution box, one end of the binding post (4) is fixedly connected with the lead of the copper bar, and the other end of the binding post (4) is sleeved on the bolt (2). According to the above structure, grounding resistance is not increased while the structure is simplified, thereby saving material of copper wires and further reducing the cost.

Description

The earthing device of distribution box
Technical field
The utility model relates to the distribution box field, is specifically a kind of earthing device of distribution box.
Background technology
Distribution box, be the complete sets of equipment of installing the equipment such as switch, instrument concentratedly, and it can reasonably distribute electric energy, the convenient operation of the folding to circuit, it has higher class of safety protection, intuitively the conducting state of display circuit, be convenient to management, also easy access when the circuit for generating fault.And in order to guarantee the safe handling of distribution box, usually be all, in the inside of distribution box, earthing device is set at present, the earthing device of prior art is generally at a bolt made of iron of the inboard welding of chamber door, and the copper cash that grounding copper bar is drawn is fastened reaches the purpose that ground connection prevents electric leakage on bolt.But, there is following problem in the earthing device of the distribution box of this structure: due in order to guarantee the stationarity between bolt and grounding copper bar, have to adopt a large amount of copper cash to be wound around, therefore, the earth resistance that on the one hand earthing device is connected increases, also waste on the other hand too much material, increased cost.
The utility model content
Technical problem to be solved in the utility model is that a kind of phenomenon that occurs that earth resistance increases, earthing device of the distribution box that simultaneously save material, reduces costs avoided is provided.
For solving the problems of the technologies described above, the grounding device of distribution box that the utility model provides, comprise the bolt made of iron be welded on the distribution box door inboard, be connected with binding post made of copper on the lead-in wire of the grounding copper bar in distribution box, one end of described binding post is fixedly connected with the lead-in wire of grounding copper bar, and the other end is socketed on bolt.
Described binding post also is fixed tightly on bolt by the nut of being made by insulating material.
After adopting above structure, the utility model compared with prior art, have the following advantages: because the lead-in wire of the grounding copper bar in distribution box just is connected with bolt by a binding post, therefore, earth resistance can not increase on the one hand, also make on the other hand simple in structurely, saved copper wire material, thereby reduced costs; In addition, the nut of also making by insulating material outside binding post and bolt tightening, guaranteed binding post and bolted fastness more.
The accompanying drawing explanation
Fig. 1 is the structural representation of the earthing device of the utility model distribution box.
Wherein: 1, nut; 2, bolt; 3, distribution box door; 4, binding post.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
The structural representation of the earthing device of the utility model distribution box as shown in Figure 1 is known, it comprises the bolt made of iron 2 be welded on distribution box door 3 inboards, be connected with binding post 4 made of copper on the lead-in wire of the grounding copper bar in distribution box, one end of described binding post 4 is fixedly connected with the lead-in wire of grounding copper bar, and the other end is socketed on bolt 2.
Described binding post 4 also is fixed tightly on bolt 2 by the nut 1 of being made by insulating material.

Claims (2)

1. the earthing device of a distribution box, comprise the bolt made of iron (2) be welded on distribution box door (3) inboard, it is characterized in that: on the lead-in wire of the grounding copper bar in distribution box, be connected with binding post made of copper (4), one end of described binding post (4) is fixedly connected with the lead-in wire of grounding copper bar, and the other end is socketed on bolt (2).
2. the earthing device of distribution box according to claim 1, it is characterized in that: described binding post (4) also is fixed tightly on bolt (2) by the nut (1) of being made by insulating material.
