Description
Technical field
The utility model relates to a kind of electric connecting part, refers in particular to the wire inlet component that the line in a kind of low-voltage cable junction box connects, and the cable that is mainly used in the line that open air, cable shaft and corridor be connected connects.
Background technology
Cable branch box is along with the development of power distribution network cable process, when the little independent load distribution of capacity is concentrated, generally used cable branch box 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 with cable distribution or switching.So-called cable distribution refers to: have many small size cables to tend to cause cable to use waste at a long circuit of distance, so in outlet in power load, often use the large cable outlet of trunk, then when approaching load, use cable branch box that main cable is divided into some small size cables, by small size cable access load.Such mode of connection is widely used in power supply, the little customer power supplies such as the street lamp in the urban distribution network.So-called Splices cable refers to: on a long circuit, the length of cable can't satisfy the requirement of circuit, that just must use cable joint or cable connection box, adopt cable intermediate joint in the time of common short distance, but when circuit is long, rule of thumb on the cable line more than the 1000M, if many transition joints are arranged in the middle of the cable, in order to ensure safety, can consider therein that cable branch box transfers.Cable branch box has been widely used in the open air, and begins in a large number to bring into use in low voltage network, and the type selecting of cable branch box is along with the power industry modernization develops rapidly, the comprehensive startup of electric network reconstruction.When underground backbone cable needed to realize multiloop branch distribution in certain distance, adopting cable branch box was not only economy but also convenient and safe a kind of way as the important corollary equipment of distribution.
Along with a large amount of uses of cable at low-voltage alternating-current, sharing of load needs a large amount of low-voltage cable junction boxes, and these feeder pillars mainly are installed in: 1. outdoor, 2. cable shaft is 3. in the corridor; These are local because temperature humidity changes greatly, and dust is many, ventilates poor, and environment is abominable, does not have the special messenger to safeguard.Therefore require these low-voltage cable junction boxes will guarantee following performance:
1. security protection is reliable;
2. can stand the rugged environment impact;
3. the least possible maintenance;
4. can install fast and easily;
5. when the user increases, can make things convenient for dilatation;
6. when faults such as being short-circuited/transshipping, require impact is limited in the minimum zone, to reduce to have a power failure area;
7. can easy-to-look-up fault.
But large quantities of distribution boxes in usefulness all are that direct copper bar connects at present, and unprotect, will cause like this:
1. contingency has the people to touch exposed copper bar line, with the danger that directly causes getting an electric shock;
2. fault has appearred in any branch road, and whole feeder pillar all is beset with a crisis;
When thinking that 3. 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 troublesomely, search in the loop one by one.
Therefore necessary this is improved.Find the patent that some are relevant by the domestic Searches of Patent Literature, the patent the most relevant with the utility model 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 ", this patent provides a kind of cable branch box, it includes casing, the casing both sides vertically are fixed with the isolated bus bracing frame, be provided with copper bar between the isolated bus bracing frame, be mounted with terminal block on the copper bar, terminal block is provided with the cable splicing ear.Simultaneously, inlet wire and outlet can be adopted independently terminal block, and the line cable need not the crimping binding post, can be directly link to each other with splicing ear on the terminal block.Whole like this inlet wire and outgoing line unit all are in the enclosed construction, and without the live part that exposes, security performance is good.And cable branch box copper bar of the present utility model need not bending, and is also lower to the required precision of copper bar design and installation.But this patent is not when fine solution thinks that dilatation increases outlet yet, and whole feeder pillar all will have a power failure, and then rearranges the problem of copper bar; And the joint that adopts common joint not yet, so still more bothersome when connecting, and be not easy to change, blank area also still violence easily cause electric shock accidents outside.
2, the patent No. is CN201020650124, patent name is the utility model patent of " a kind of cable branch box ", this patent discloses 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 the described sleeve pipe, the inlet wire cable and the outlet cable that access in the described casing are connected to respectively described T-shaped plug, described inlet wire cable links to each other with described outlet cable with described T-shaped plug by the described sleeve pipe that mutually is socketed successively and forms the tap loop, described sleeve pipe is the shunt sleeve pipe, described shunt sleeve pipe has three road line sockets at least, and at least one road line socket is pegged graft and fixed an earthing device.But this patent is the problem of unresolved exposed copper bar line still, and structure is very complicated, install and change inconvenient, dilatation trouble especially.
3, the patent No. is CN201020172082.5, and patent name is the utility model patent of " low-voltage cable junction box ", and this patent discloses a kind of low-voltage cable junction box, and it comprises casing, case lid and is located at casing interior copper busbar and circuit breaker; It is characterized in that, it also comprises the closed busbar system for the sealing copper busbar; Described casing is the nonmetal insulation shell that the unsaturated polyester resin glass fibre reinforced mould plastic material is made; Simultaneously, the box house copper busbar adopts the closed busbar system sealing of insulation, prevents the artificial possibility of getting an electric shock of operating personnel, makes its handling safety, guarantees the 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 has solved the exposed problem of copper bar, this patent is the problem of unresolved how dilatation still, can't 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 ", this patent discloses a kind of low-voltage cable junction box, include casing, it is characterized in that: bottom half has wire inlet/outlet hole, mounting bracket is arranged in the casing, several are installed with the switch of fuse on mounting bracket; The three-phase inlet wire is introduced from a perforate on the bottom half, and be divided into array three-phase outlet branch road, draw from other perforate of casing side bottom, be serially connected with respectively one with the switch of fuse on every phase inlet wire, also be serially connected with respectively one with the switch of fuse in every phase outlet of every group of three-phase outlet branch road.But this patent is still taked common copper bar line, the problem that not fine solution copper bar is exposed, the easily danger of outlet electric shock.
In sum, all there is foregoing problem to some extent in existing various low-voltage cable junction boxes, therefore still are necessary this is further improved.
