Abstract

The utility model provides a copper bus bar with an improved structure. The copper bus bar comprises a body and a plurality of threaded pieces, wherein a plurality of penetrable holes that are formed in the body with equal intervals; each threaded piece is assembled in the corresponding penetrable hole; a threaded arrangement part for locking of a screw is arranged on each threaded piece; and an embedding part is arranged at one end of each threaded piece. The embedding parts can be embedded with the penetrable holes mutually, so that the threaded pieces are fixed on the body; the screws can be prevented from thread shedding or loosening by virtue of the threaded pieces; and burnout of a switch box due to poor contact cannot be caused.

Description

The confluence copper bar of architecture advances

Technical field

The utility model is relevant for a kind of confluence copper bar of architecture advances, especially refers to a kind ofly can prevent screw generation debentition or sliding tooth, thereby the confluence copper bar that can not cause loose contact that switch-box is burnt.

Background technology

Existing in the confluence copper bar 20 in switch-box, as shown in Figure 4, because be with the directly tapping on confluence copper bar 20 of geometric ratio distance, make it form a plurality of screws 201, allowing screw 3 directly lock, yet still there is following shortcoming in the confluence copper bar 20 of the direct tapping of this kind:

1, because existing confluence copper bar 20 variable thickness, if after meeting thinner confluence copper bar 20 tapping in the above of thickness low LCL, its formed screw 201 degree of depth are inadequate, thereby when the assembled switch case, are very easy to allow screw 3 get loose with screw 201 locking the time;

2, the confluence copper bar 20 of existing use, because form the copper screw thread of one deck tool in the interior meeting of tapping rear bolt hole 201, yet this copper screw thread is because of the softer relation of quality, be easy to occur the situation of debentition or sliding tooth when screw 3 locking, therefore easily cause the contact loose contact, can cause switch-box to burn when serious, therefore existing confluence copper bar 20 structures have and change further improvement.

The utility model content

Technical problem to be solved in the utility model is to provide and a kind ofly can prevents screw generation debentition or sliding tooth situation when the assembled switch case, thereby can not cause loose contact to make the confluence copper bar of the architecture advances that switch-box burns.

The utility model provides a kind of confluence copper bar of architecture advances, comprising:

One body, two ends respectively have a pivoted hole, and have a plurality of perforation of equidistant setting on this body;

A plurality of screw pieces, each screw piece is mounted in corresponding perforation, has on this each screw piece for a spiral shell of a screw locking to establish section, and has a fitting portion on each screw piece one end, this fitting portion and this perforation are mutually chimeric, and each screw piece is fixed on body.

This spiral shell is established has the screw thread that agrees with mutually with this screw on the section surface.

This body is one to be the metallic object of flat outward appearance.

Comprise also on this body surface that one has the sleeve pipe of insulation function.

The advantage that the utlity model has is: the confluence copper bar of the architecture advances that the utility model provides, wherein screw part has and makes screw with confluence copper bar function and the advantages such as mutual locking tightly, therefore the situation of screw debentition or sliding tooth can not occur in the confluence copper bar of the architecture advances that provides of the utility model, does not cause loose contact and switch-box is burnt so the coping screw debentition more can not occur.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and being implemented, but illustrated embodiment is not as to restriction of the present utility model.

As Fig. 1～shown in Figure 2, the combination schematic diagram of the confluence copper bar of the schematic perspective view of the confluence copper bar of the architecture advances that provides for the utility model, the architecture advances that the utility model provides, the confluence copper bar 10 of the architecture advances that provides of the utility model as shown in the figure, include a body 1, the metallic object that is the flat outward appearance, two ends respectively have a pivoted hole 12, and have a plurality of perforation 11 of equidistant setting on this body 1;

a plurality of screw pieces 2, each screw piece 2 is mounted in corresponding perforation 11, have on this each screw piece 2 for a spiral shell of screw 3 lockings and establish section 21, and has a fitting portion 22 on each screw piece 2 one end, this fitting portion 22 is mutually chimeric via high pressure mode and this perforation 11, each screw piece 2 is fixed on body 1, this spiral shell is established and is had the screw thread 211 that agrees with mutually with this screw 3 on section 21 surfaces in addition, and also include a sleeve pipe 13 with insulation function on this body 1 surface, to prevent Danger Electric shock risk, consist of a brand-new confluence copper bar structure by above-mentioned structure.

Be illustrated in figure 3 as the confluence copper bar embodiment schematic diagram of the architecture advances that the utility model provides, coordinate Fig. 1, shown in Figure 2, when in the assembled switch case, with a plurality of confluence copper bar 10 in 4 arrangements of switch, then the pivoted hole 12 of confluence copper bar 10 is established with switch 4 contact groups, and recycling screw 3 can progressively be completed the assembling of switch-box and confluence copper bar with confluence copper bar 10 mutual locking tightly.

Conclude above-mentioned, the confluence copper bar of the architecture advances that the utility model provides is when the assembled switch case, really having by this screw piece 2 makes screw 3 with confluence copper bar 10 function and the advantages such as mutual locking tightly, therefore the situation of debentition or sliding tooth can not occur in the confluence copper bar of the architecture advances that provides of the utility model really, so more do not have coping screw 3 debentitions, and cause loose contact that switch-box is burnt, therefore really can reach the purpose of this utility model.

To sum up institute is old, and the confluence copper bar of the architecture advances that the utility model provides obviously more can allow screw locking tightly, and can the coping screw debentition not cause loose contact and switch-box is burnt, and therefore has economic benefit, and has novelty with creative.

The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and protection range of the present utility model is not limited to this.Being equal to that those skilled in the art do on the utility model basis substitutes or conversion, all within protection range of the present utility model.Protection range of the present utility model is as the criterion with claims.
