Abstract
The utility model discloses a cabinet body grounding structure. The cabinet body grounding structure comprises a grounding copper block (1), a grounding copper busbar (2), a connecting screw (3) and a cabinet body grounding support (4), wherein a round hole is drilled in the cabinet body grounding support (4); a threaded hole is drilled in the grounding copper block (1); the grounding copper block (1) is welded below the cabinet body grounding support (4); the round hole in the cabinet body grounding support (4) is aligned with the threaded hole in the grounding copper block (1); the connecting screw connects together and tightly screw the grounding copper busbar (2), the cabinet body grounding support (4) and the grounding copper block (1). According to the cabinet grounding structure, even if the grounding copper block drops off due to dry joint or other reasons, the grounding copper busbar is still tightly adhered to the cabinet body support, the grounding is still effective; and furthermore, the contact area of the grounding copper busbar and the cabinet grounding support increases, and the reliability in grounding is improved.
Description
Technical field
The utility model relates to a kind of cabinet ground structure, particularly relates to a kind of difficult drop-off, and the ground connection contact-making surface is large, the reliable cabinet ground structure of ground connection.
Background technology
At present, the earthing device of various regulator cubicles generally adopts Welding Structure, usually ground connection copper billet (nut) is welded on directly over the round-meshed support, then by screw grounding copper busbar, cable and ground connection copper billet is linked together.In the earthing device process of manufacture, the ground connection copper billet often has rosin joint or sealing-off phenomenon to occur, cause whole ground connection copper billet (nut) when assembling, just to come off easily, the whole grounding copper busbar and the cable that cause being attached thereto above all fall down, thereby cause the earthing failure of whole cabinet, and owing to the grounding copper busbar contacts with cabinet indirectly by ground connection copper billet (nut), contact area between them only is the part between ground connection copper billet (nut) and the grounding copper busbar, and contact area is very limited.
The utility model content
For the problems referred to above, main purpose of the present utility model is to provide a kind of cabinet ground structure, solves that present cabinet ground connection copper billet comes off easily, the ground connection contact-making surface is little, the insecure problem of ground connection.
The utility model solves the problems referred to above by following technical proposals:
A kind of cabinet ground structure, comprise the ground connection copper billet, the grounding copper busbar, attachment screw, the cabinet grounded bracket, be drilled with circular hole at described cabinet grounded bracket, be drilled with screwed hole on the described ground connection copper billet, described grounding copper block welding is at the lower surface of described cabinet grounded bracket, and the circular hole of described cabinet grounded bracket aligns with the screwed hole of described ground connection copper billet, described attachment screw passes the through hole on the described grounding copper busbar successively, and the screwed hole of the circular hole of described cabinet grounded bracket and described ground connection copper billet is tightened, and the upper surface of the lower surface of described grounding copper busbar and described cabinet grounded bracket is close together.
In specific embodiment of the utility model, described ground connection copper billet can be copper nut.
Positive progressive effect of the present utility model is: a kind of cabinet ground structure that the utility model provides, by with the lower surface of grounding copper block welding at the cabinet grounded bracket, then with attachment screw with grounding copper busbar and cabinet grounded bracket, the ground connection copper billet links together, even the ground connection copper billet is owing to the reasons such as rosin joint come off, the grounding copper busbar is because the connection function of attachment screw and ground connection copper billet, the grounding copper busbar still is close together with the cabinet grounded bracket, ground connection is still effective, and the grounding copper busbar directly contacts with the cabinet grounded bracket, greatly increase the contact area between them, improved the reliability of ground connection.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Describe most preferred embodiment of the present utility model in detail below in conjunction with Fig. 1.
As shown in Figure 1, a kind of cabinet ground structure that the utility model relates to, comprise ground connection copper billet 1, grounding copper busbar 2, attachment screw 3, cabinet grounded bracket 4, be drilled with circular hole at cabinet grounded bracket 4, be drilled with screwed hole on the ground connection copper billet 1, ground connection copper billet 1 is welded on the lower surface of cabinet grounded bracket 4, and the circular hole of cabinet grounded bracket 4 aligns with the screwed hole of ground connection copper billet 1, attachment screw 3 passes the through hole on the grounding copper busbar 2 successively, the screwed hole of the circular hole of cabinet grounded bracket 4 and ground connection copper billet 1 is tightened, and the upper surface of the lower surface of grounding copper busbar 2 and cabinet grounded bracket 4 is close together, and ground connection copper billet 1 is copper nut.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
