Abstract

A bidirectional power supply de-concentrator comprises a top lid, a de-concentrator base, a main line hold-down mechanism, a branch line hold-down mechanism, a semi-circular main line slot and a group of branch slots which are formed by branch slots with embedded conductive strips. The main line slot and the branch slot are vertically crossed to be arranged on the de-concentrator base, and the main line hold-down mechanism is installed on every main line slot. The main line is connected with the embedded conductive strips in the branch line slot through the hold-down mechanism. The branch line hold-down mechanism is arranged at the interface which is arranged on two ends of the branch line slot, and is characterized in that the main line hold-down mechanisms among the main line slot are in staggered arrangements relatively to inlets which are arranged at the main line slot. Because the technical proposal is adopted, the utility model has the advantages of compact conformation, easy installation, stabilization and reliable operation. The utility model uses the space of the de-concentrator base to increase the distance between core hold-down current-carrying portions of the main line, thereby substantially increasing insulating ability and avoiding accidents.

Description

The bidirectional power supply deconcentrator

Affiliated technical field

The utility model relates to a kind of power wiring device, particularly a kind of bidirectional power supply deconcentrator.

Background technology

At present, in electric power supply installation process, people install deconcentrator usually and come to tell service main from backbone on wire casing.The unidirectional deconcentrator of general employing, this deconcentrator is made up of deconcentrator seat, terminal strip, main line hold-down mechanism and loam cake, described main line hold-down mechanism is on the bolt that is fixed on the deconcentrator seat, and its parts are various easily to be scattered, and makes troubles for installation or maintenance because separated time is aerial work mostly; Because the arrangement of hold-down mechanism is unreasonable, cause the volume of deconcentrator to increase, deconcentrator just can not be bumped in the wire casing when installing, deconcentrator only can be by self and can not be by wire casing and external insulation, not only reduced fail safe, and influenced aesthetic feeling in the wire casing because of not placing.The two-way deconcentrator of employing is also arranged now, and the main line hold-down mechanism of this deconcentrator generally is arranged in parallel, and two main lines bump together easily in use, cause security incident, and when this deconcentrator was installed, deconcentrator seat and draw-in groove were not tight, in use, can become flexible, even can come off.

Summary of the invention

It is reliable that the purpose of this utility model just provides between a kind of main line insulation, separated time bi-directional distributed, compact conformation, easy for installation, firm and safe and reliable bidirectional power supply deconcentrator.

The purpose of this utility model is to realize by such technical scheme, it comprises loam cake, deconcentrator seat, main line hold-down mechanism, separated time hold-down mechanism, semicircle main line groove and is embedded with formed minute wire casing group of branch wire casing of bus, wherein, described main line groove is being arranged on the deconcentrator seat of square crossing with dividing wire casing, be provided with a main line hold-down mechanism on each main line groove, by this hold-down mechanism with main line with divide wire casing in pre-buried bus be electrically connected; The separated time hold-down mechanism is arranged on the connection jaws place at branch wire casing two ends; It is characterized in that: each the main line hold-down mechanism between the main line groove is dislocation arrangement each other corresponding to the incoming line of main line groove.

The utility model is to use like this: at first the deconcentrator seat is placed on the body of wall, treated backbone and service main are placed on respectively in main line groove and the branch wire casing, and the core of backbone or service main is contacted with bus, compress backbone and service main by main line hold-down mechanism and separated time hold-down mechanism again, interlaced with each other between the main line hold-down mechanism, the distance that the core of backbone is compressed between the current-carrying part is bigger, and the obvious like this insulation property that increased have been avoided the generation of accident.

Owing to adopted technique scheme, the utlity model has compact conformation, easy for installation, firm and safe and reliable advantage, it has rationally utilized the space of deconcentrator seat, the distance that the core of backbone is compressed between the current-carrying part is bigger, the obvious like this insulation property that increased have been avoided the generation of accident.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

Shown in Fig. 1,3 or 4, the utility model comprises loam cake 1, deconcentrator seat 2, main line hold-down mechanism 3, separated time hold-down mechanism 4, semicircle main line groove 5 and is embedded with 7 formed minutes wire casing groups of branch wire casing of bus 6, wherein, described main line groove 5 is being arranged on the deconcentrator seat 2 of square crossing with dividing wire casing 7, be provided with a main line hold-down mechanism 3 on each main line groove 5, by this hold-down mechanism with main line with divide wire casing in pre-buried bus be electrically connected; Separated time hold-down mechanism 4 is arranged on the connection jaws place at branch wire casing 7 two ends; It is characterized in that: each the main line hold-down mechanism 3 between the main line groove 5 is dislocation arrangement each other corresponding to the incoming line of main line groove.Shown in Fig. 1 or 3, be provided with strengthened connection bar 8 between described main line groove 5 and the deconcentrator seat 2.Shown in Fig. 2 or 6, the connection jaws place correspondence of covering 9 two ends at 1 fen wire casing of loam cake is provided with frangibility formula cover plate 10.Shown in Fig. 2 or 6, have breach 11 between described cover plate 11 and the loam cake 1.In conjunction with shown in Figure 5, the corresponding lead seal hole 12 that is provided with on loam cake 1 and the deconcentrator seat 2.By lead seal hole with loam cake with the deconcentrator seat lead sealing be in the same place, can prevent that the layman from opening deconcentrator without authorization, both played safety effect, can prevent from again to steal.

The utility model in use, at first deconcentrator seat 2 is placed on the body of wall, be stuck in the draw-in groove on the body of wall by dowel 8, dowel plays the effect of chucking, prevented that the deconcentrator seat is loosening, again treated backbone and service main are placed on respectively in main line groove 5 and the branch wire casing 7, and the core of backbone or service main is contacted with bus 6, compress backbone and service main by main line hold-down mechanism 3 and separated time hold-down mechanism 4 again, interlaced with each other between the main line hold-down mechanism 3, the distance that the core of backbone is compressed between the current-carrying part is bigger, and the obvious like this insulation property that increased have been avoided the generation of accident.Can also be stuck in the draw-in groove on the body of wall by dowel 8, dowel plays the effect of chucking, has prevented that the deconcentrator seat is loosening,

The effect of above-mentioned cover plate is: when not using, cover plate 10 is that minute wire casing 7 is covered, promptly reach the purpose of sealing separated time mouth, attractive in appearance again, in use, the operator can fracture cover plate along breach 11 easily with hand, so just service main can be electrically connected with bus 6, and untapped separated time mouth is still covered by cover plate 10, helps dustproof and prevents that electric conductor from entering in the deconcentrator, causes and opens circuit or the generation of other security incident.
