Description
Technical field
The present invention relates to a kind of electric connecting mode and device, refer in particular to the line connected mode in a kind of low-voltage cable junction box and device, be mainly used in open air, cable shaft is connected with the cable of the line in corridor.
Background technology
Cable branch box is along with the development of power distribution network cable process, when the individual load distribution that capacity is little is comparatively concentrated, cable branch box has generally been used to carry out the connection of cable multi-branch, because feeder pillar can not directly operate every road, only use as cable branch, the Main Function of cable branch box is by cable distribution or switching.So-called cable distribution refers to: often cause cable to use waste at one apart from long circuit there being many small size cables, so in outlet in power load, often use the large cable outlet of trunk, then in close to load, use cable branch box main cable to be divided into some small size cables, access load by small size cable.Such mode of connection is widely used in power supply, the little customer power supplies such as the street lamp in urban distribution network.So-called Splices cable refers to: on a long circuit, the length of cable cannot meet the requirement of circuit, that just must use cable joint or cable connection box, cable intermediate joint is adopted when usual short distance, but time circuit is long, rule of thumb on the cable line of more than 1000M, if having many transition joints in the middle of cable, in order to ensure safety, can consider that cable branch box is transferred wherein.Cable branch box is widely used in open air, and starts in a large number to bring into use in low voltage network, type selecting the developing rapidly along with power industry modernization of cable branch box, the comprehensive startup of electric network reconstruction.Underground backbone cable, when certain distance needs to realize multiloop branch distribution, adopts cable branch box to be not only economy but also convenient and safe a kind of way as the important corollary equipment of distribution.
Along with cable is in a large amount of uses of low-voltage alternating-current, sharing of load needs a large amount of low-voltage cable junction boxes, and these feeder pillars are mainly arranged on: 1. outdoor, 2. cable shaft, 3. in corridor; These places due to temperature humidity change greatly, dust is many, ventilates poor, and bad environments, does not have special messenger to safeguard.Therefore require that these low-voltage cable junction boxes will ensure following performance:
1. security protection is reliable;
2. rugged environment impact can be stood;
3. the least possible maintenance;
4. can install fast and easily;
5., when user increases, dilatation can be facilitated;
6., when faults such as being short-circuited/transshipping, require impact to be limited in minimum zone, to reduce power failure area;
7. can easy-to-look-up fault.
But, at present large quantities of with distribution box be all that direct copper bar connects, and unprotect, will cause like this:
1. just in case the copper bar line that to have had people to touch exposed, the danger of getting an electric shock will directly be caused;
2. there is fault in any branch road, and whole feeder pillar is all beset with a crisis;
When 3. thinking that dilatation increases outlet, whole feeder pillar all will have a power failure, and then rearranges copper bar;
If when 4. breaking down, search also pretty troublesome, must search in loop one by one.
Therefore necessary this to be improved.Find some relevant patents by the domestic Searches of Patent Literature, the patent the most relevant to the present invention mainly contains following several:
1, the patent No. is CN201120015501.9, patent name is the utility model patent of " a kind of cable branch box ", the patent provides a kind of cable branch box, it includes casing, casing both sides are vertically fixed with isolated bus bracing frame, be provided with copper bar between isolated bus bracing frame, copper bar is mounted with terminal block, terminal block is provided with cable connecting terminals.Meanwhile, inlet wire and outlet can adopt independently terminal block, and line cable is without the need to crimping binding post, can directly be connected with the splicing ear on terminal block.Whole like this inlet wire and outgoing line unit are all in enclosed construction, and without the live part exposed, security performance is good.And cable branch box copper bar of the present utility model is without the need to bending, also lower to the required precision of copper bar design and installation.But when this patent does not solve very well yet and thinks that dilatation increases outlet, whole feeder pillar all will have a power failure, and then rearranges the problem of copper bar; And the joint that the joint adopted is common not yet, so connect time still more bothersome, and be not easy change, blank area also still violence outside, easily cause electric shock accidents.
2, the patent No. is CN201020650124, patent name is the utility model patent of " a kind of cable branch box ", which disclose a kind of cable branch box, comprise casing, the built-in sleeve pipe of described casing and grafting are fixed on the T-shaped plug on described sleeve pipe, access inlet wire cable in described casing and outlet cable is connected to described T-shaped plug respectively, described inlet wire cable is connected to form tap loop by the described sleeve pipe of mutually socket and described T-shaped plug and described outlet cable successively, described sleeve pipe is shunt sleeve pipe, described shunt sleeve pipe has three road line sockets at least, an earthing device is fixed in the line socket grafting of at least one road.But the problem of this patent still unresolved exposed copper bar line, and structure is very complicated, installs and change inconvenient, especially dilatation trouble.
3, the patent No. is CN201020172082.5, and patent name is the utility model patent of " low-voltage cable junction box ", which discloses a kind of low-voltage cable junction box, and it comprises casing, case lid and the copper busbar be located in casing and circuit breaker; It is characterized in that, it also comprises the closed busbar system for closed copper busbar; Described casing is the non-metallic insulation housing that unsaturated polyester resin glass fibre reinforced mould plastic material is made; Meanwhile, box house copper busbar adopts the closed busbar system of insulation to close, and prevents the possibility that operating personnel artificially get an electric shock, makes its handling safety, guarantee power consumer safe operation; And bus-bar system adopts unsaturated polyester resin glass fiber reinforced plastics shell, novel structure, favorable sealing property; It has easy for installation, cost is low, aesthetic in appearance, highly versatile, the advantage that dismounting is flexible.Although this patent solves the exposed problem of copper bar, the problem of this patent still unresolved how dilatation, cannot carry out dilatation, and if uniline damage, must all change.
4, the patent No. is CN200920180719.2, patent name is the utility model patent of " low-voltage cable junction box ", which disclose a kind of low-voltage cable junction box, include casing, it is characterized in that: bottom half has wire inlet/outlet hole, there is mounting bracket in casing, mounting bracket is provided with several switch with fuse; Three-phase inlet wire is introduced from the perforate of bottom half, and be divided into array three-phase outlet branch road, draw from other perforate of casing side bottom, every phase inlet wire is serially connected with respectively a switch with fuse, the every phase outlet often organizing three-phase outlet branch road is also serially connected with a switch with fuse respectively.But this patent still takes common copper bar line, do not solve the exposed problem of copper bar very well, the danger that easy outlet is got an electric shock.
In sum, there is foregoing problem in existing various low-voltage cable junction box all to some extent, is therefore still necessary to be further improved this.
