Abstract
The utility model discloses an insulation pipe for a branch bus in a low-voltage electric switch cabinet, which comprises a long cylinder-shaped pipe body with a hollow cavity, one end of the pipe body is provided with a convex column, the other end thereof is provided with a concave hole which can be clamped and matched with the convex column, the side face of the pipe body is evenly provided with a plurality of inserting cylinders, the inner ends of the inserting cylinders are communicated with the hollow cavity of the pipe body, the outer ends of the inserting cylinders are provided with a sealing cover, the outer end of the convex column is provided with a ring-shaped lug boss, and the inner end of the concave hole is provided with a ring-shaped groove which can be clamped and matched with the ring-shaped lug boss. The insulation pipe has simple structure, is practical and convenient, has good insulation effect, can not affect adjoining phase when going wrong, can not cause inter-phase arc discharge or short circuit, is very convenient in maintaining or replacing, has good universality, can be suitable for the branch bus with different types, has good mechanical strength, and can not lead the branch bus to be deformed when going wrong.
Description
Technical field
The utility model belongs to a kind of spare and accessory parts of power supplying and distributing equipment, particularly a kind of insulated tube that is used on the interior branch bar of low tension switch cubicle.
Background technology
The branch bar of low tension switch cubicle is more, in the time of wiring, need carry out insulation processing to every adjacent branch bar, existing insulation mode mainly contains three kinds: first kind is naked dew type, insulation between the branch bar is by keeping the distance between them to realize, this mode is easily arcing short circuit and causing the accident between phase and phase when breaking down, therefore, this insulation mode generally is used in the middle of the low-grade equipment.Second kind is to be arranged with heat-shrinkable T bush on branch bar, though this mode can reach the good insulation requirement, the mechanical strength of branch bar is relatively poor when breaking down, and easily causes torsional deformation, even the accident that can therefore be short-circuited.The third is all insulation type, the three-phase branch bar is an one by a kind of designing requirement and insulating material pressure injection, the insulation property of this insulation mode and mechanical strength are all better, its shortcoming is that the designing requirement when branch bar simultaneously just can not be not general, and when causing local damage when breaking down, whole electric switch cabinet just can't keep in repair and can't use.
The utility model content
The utility model provides a kind of insulated tube on the branch bar in the low tension switch cubicle that is used in order to solve weak point of the prior art, and it has good insulation performance performance, mechanical strength and versatility, and is easy to the dismounting maintenance when breaking down.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: be used for the insulated tube on the branch bar in the low tension switch cubicle, comprise the long tubular body with cavity, described body one end is provided with projection, and the other end is provided with the shrinkage pool that can cooperate with the projection clamping.
Described body side evenly is provided with several tubes of pegging graft, and the tube of pegging graft is inner to be communicated with the cavity of body, and the outer end of the tube of pegging graft is provided with seal cover.
Described projection outer end is provided with annular boss, and shrinkage pool the inner is provided with the annular recess that can cooperate with the annular boss clamping.
Adopt said structure, branch bar is located in the cavity of body, and the connection between the body cooperates by the clamping between projection and the shrinkage pool, makes the whole insulation of branch bar and does not have exposed; In the grafting tube plug can be set, seal cover plays the sealed insulation effect, only just seal cover is opened when plug inserts; The structure of annular boss and ring-type shrinkage pool and between the mode that cooperates by clamping connect, simple in structure, easy and simple to handle; The body and the tube of pegging graft adopt once injection moulding, mechanical strength height; Simple in structure, the practical convenient of the utility model, insulation effect is good, do not influence adjacent phase when breaking down, can not cause alternate arcing or short circuit, maintenance or replacing are also very convenient, and versatility is good, applicable to the branch bar of different model, mechanical strength is good, and the Shi Buhui that breaks down causes the torsional deformation of branch bar.

Fig. 2 is the left view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, the insulated tube that is used on the interior branch bar of low tension switch cubicle of the present utility model comprises the long tubular body 2 with cavity 1, and body 2 one ends are provided with projection 3, and the other end is provided with the shrinkage pool 4 that can cooperate with projection 3 clampings.Projection 3 outer ends are provided with annular boss 5, and shrinkage pool 4 the inners are provided with the annular recess 6 that can cooperate with annular boss 5 clampings.Body 2 sides evenly are provided with several tubes 7 of pegging graft, and tube 7 the inners of pegging graft are communicated with the cavity 1 of body 2, and the outer end of the tube 7 of pegging graft is provided with seal cover 8.Body 2, the tube 7 of pegging graft adopt the integrative-structure of single injection-molded, so not only have excellent mechanical intensity, also have good versatility.
When work is used, branch bar is located in the cavity 1 of body 2, annular boss 5 by projection 3 outer ends between the adjacent body 2 cooperates the mode that is sealedly and fixedly connected with annular boss 5 clampings of shrinkage pool 4 the inners, uses the body 2 of some according to the length of branch bar.In the same way to the operation of insulating of other branch bar.When plug will be inserted into when pegging graft tube 7, seal cover 8 is opened get final product.
Claims (3)
1. be used for the insulated tube on the branch bar in the low tension switch cubicle, comprise the long tubular body with cavity, it is characterized in that: described body one end is provided with projection, and the other end is provided with the shrinkage pool that can cooperate with the projection clamping.
2. the insulated tube that is used on the interior branch bar of low tension switch cubicle according to claim 1 is characterized in that: described body side evenly is provided with several tubes of pegging graft, and the tube the inner of pegging graft is communicated with the cavity of body, and the outer end of the tube of pegging graft is provided with seal cover.
