Abstract

The utility model discloses a tubular bus-bar end joint which comprises a bus tube, conducing sleeves sleeved on the outer wall of the ends of the bus tube and fixing devices mounted outside the conducing sleeves. The tubular bus-bar end joint is simple in structure and convenient to install, forms smaller contact resistance at the joint, avoids the generation of excessive heat and conforms to the requirements for safe operation.

Description

Pipe bus bar terminal joint

Technical field

The utility model relates to circuit interconnection technique field, is specifically related to a kind of pipe bus bar terminal joint.

Technical background

All there is following shortcoming in existing contact tube busbar joint in the actual installation process:

Need install conversion gold additional when one, being connected with equipment, increase installation cost owing to the contact tube bus.

Two, pipe bus end is connected with conversion gold, can produce contact resistance, under the situation of carrying big electric current, pipe bus end and conversion gold can produce excessive heating, its connection situation is more not tight, and resistance is just big more, and the heating phenomenon is just serious more, cause and blow pipe bus, phase fault, shorted to earth, even initiation fire causes bigger accident.

In sum, develop a kind of pipe bus bar terminal joint simple in structure, safe in utilization, become the technical problem that presses for solution in the industry.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of pipe bus bar terminal joint, and it is simple in structure, security performance is high.

For achieving the above object, the utility model adopts following technical scheme:

A kind of pipe bus bar terminal joint comprises bus pipe, and the terminal outer wall of described bus pipe is socketed with conductive sleeve, and the outside of described conductive sleeve is equipped with fixture.

Described fixture is a plurality of snap rings that are socketed on described conductive sleeve outside.

Described conductive sleeve comprises symmetrically arranged two conducting elements up and down, and the end that described conducting element is connected with described bus pipe is the semicircle tubulose, and the outer diameter of its inner diameter and described bus pipe is suitable; Its other end is a plate connecting terminal.

The pipe bus bar terminal joint that the utility model is set forth, its beneficial effect is, because adopting the snap ring of outside socket fixes, make conductive sleeve and bus pipe strong bonded, avoided the appearance of big contact resistance in its junction, the caloric value of whole connector portions effectively is controlled in the reasonable range, has guaranteed its fail safe, other end plane can easily link to each other with transformer or switch cubicle terminal; The utility model is simple in structure, easy for installation simultaneously.

Fig. 2 is the A-A cutaway view of Fig. 1.

Embodiment

Below, in conjunction with the accompanying drawings and embodiment, pipe bus bar terminal joint of the present utility model is described further:

As shown in Figure 1, 2, be a kind of pipe bus bar terminal joint of the present utility model, it comprise bus pipe 1, on conduct electricity copper sheathing 21, conduct electricity copper sheathing 22, two outer snap rings 3 down; The last conduction copper sheathing 21 and the copper sheathing 22 that conducts electricity down are symmetrical arranged up and down, its both ends of being connected with bus pipe 1 are the semicircle tubular structure, and the outer diameter of inner diameter and bus pipe 1 is suitable, and the other end is respectively plate terminal fitting 211,221, links to each other with transformer or switch cubicle terminal; Two outer snap rings 3 are sleeved on conduction copper sheathing 21, conduct electricity copper sheathing 22 outsides down, by the tension to snap ring 3, will go up conduction copper sheathing 21, conduct electricity copper sheathing 22 down and firmly be fixed on the bus pipe 1; Last conduction copper sheathing 21, conduct electricity the combining closely of copper sheathing 22 and bus pipe 1 down, form small contact resistance, the unsafe factor of having avoided excessive heating to cause in the joint.

Aforementioned tube bus bar terminal joint is being peelled off two stainless steel wild card ring sets on the bus pipe termination of coating layer earlier when mounted, makes the conduction copper sheathing and conduct electricity the semicircle pipe end of copper sheathing down to embrace position, termination at bus pipe; Again two stainless wild card ring sets are moved to the conduction copper sheathing and be an end outside of cylindrical tube shape; Respectively two stainless outer snap rings are clamped with special tooling then and make extended distance less than 1mm, weld fixingly, and butt welded seam carries out grinding process; Clear up the whole terminal joint at last.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of the utility model claim all according to technical scheme described above and design.
