Abstract
The invention discloses a novel type single-phase cable branch box which comprises a bus bar and a metal case body with internal insertion type terminal holes and external insertion type terminals wherein the inner parts of the internal insertion type terminal holes and the external insertion type terminals are connected to the bus bar. The inner part of the bus bar is coated with a conductor shielding layer. The inner surface of the metal case body is coated with an insulation shielding layer and is filled with a resin insulation layer. According to the invention, a cable connector is mounted on the same cable connector box and is small in size. At the same time, the branch cables are connected by the plurality of internal insertion type terminals and external insertion type terminals and are distributed on all facets of the cable connector box in a stereoscopic structure so that the inlet and outlet connections of the branch cables are conspicuous for people to install and recognize. When three such cable branch boxes are installed in a line, a group of three-phase branch connector boxes are formed. The connector box can be conveniently assembled for three branches, four branches and even more. Small in size and light in weight, the connector can be conveniently mounted on towers, walls, grounds or tunnels.
Description
Technical field
The present invention relates to power cable field, specifically a kind of novel single-phase cable branch box.
Background technology
Existing cable branch box is generally adopted by assembling in casing with thermal contraction formula cable termination or Cold-contraction cable accessory, it can meet the requirement of major part cable work, but owing to being air insulation, need often to safeguard, particularly frequently result in, in the plague of rats seriously area or toy area of often haunting, the short circuit accident that animal causes.If it addition, cable branch box box volume is less, construction and installation are all inconvenient, often result in cable accessory damage, and service life declines to a great extent, and all bring unnecessary trouble to user with safeguarding；If cable branch box body needs to take larger area soil, then economical and all unsatisfactory safely.
Summary of the invention
The technical problem to be solved is to provide a kind of novel single-phase cable branch box of electricity with good economy, safety, and volume is little, compact conformation, and mechanical performance and electric property are good, can at various environment life-time service.
The present invention includes inside and has the metal cabinet of bus-bar, interpolation type terminal hole and outside plug type terminal, and wherein interpolation type terminal hole is connected with bus-bar with the inside of outside plug type terminal；Described bus-bar internal coat has conductor shield, and described metal cabinet inner surface is coated with insulation screen, and inside is filled with resin insulating barrier.
Improving further, described bus-bar is circular copper conductors or copper pipe, and described conductor shield is semiconductive material.
Improving further, described metal cabinet sidewall is provided with the fixing bolt of installation and earth stud, is convenient to installation fixing.
Improving further, described resin insulating barrier is epoxy resin insulating layers.
The present invention has the advantage that compared to existing technology
1, all insulation, full-shield, hermetically sealed.Product is tangible, completely waterproof, corrosion-resistant, even if under the cable shaft of harsh environmental conditions, and still can be properly functioning.Product has significantly high security reliability.
2, not only there is hard indeformable good mechanical properties, and have higher electric property, also because having the inside and outside double shield structure of uniqueness, make internal electric field obtain control more effective, more reliable.It addition, be connected with having elastic cable plug formula terminal, form again the connection combination of the best, make connection very reliable, do not need to safeguard after longtime running.
3, cable connector is on same cable-joint protector box, and volume is very little, simultaneously, the branch multiple interpolation type terminal of bus-bar and outside plug type terminal couple together, and be distributed on each face of connector box, structure spatially, allow branch into and out of line distribution substantially, install and distinguish convenient.
4, volume is little, compact conformation, has multiple combination, and product can meet the requirement in confined space installation and various bifurcation approach, and installation method simple possible, erector does not manually need special training.
5, product has separability, changes simplicity, once cable or cable plug formula terminal break down in running, as long as pulling up failure cable to change cable in stock, time saving and energy saving, shortens emergency repair time.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is side view of the present invention.
Fig. 3 is present invention application schematic diagram.
Detailed description of the invention
Present configuration as depicted in figs. 1 and 2, has the metal cabinet 1 of bus-bar 3, interpolation type terminal hole 5 and outside plug type terminal 6 including inside, and wherein interpolation type terminal hole 5 is connected with bus-bar 3 with the inside of outside plug type terminal 6；Described bus-bar 3 internal coat has conductor shield 4, and described metal cabinet 1 inner surface is coated with insulation screen 2, and inside is filled with epoxy resin insulating layers 7, and metal cabinet 1 sidewall is provided with the fixing bolt 8 of installation and earth stud 9.
Described bus-bar 3 is circular copper conductors or copper pipe, and described conductor shield 4 is semiconductive material.
When the present invention manufactures, at metal cabinet inner surface insulation screen, then it is inserted into conductor at metal cabinet, after reserved good jack, in metal cabinet, builds resin insulating barrier.
The present invention by cable connector on same cable-joint protector box, volume is very little, simultaneously, the branch multiple interpolation type terminal of bus-bar and outside plug type terminal couple together, and it is distributed on each face of connector box, structure spatially, allow branch into and out of line distribution substantially, install and distinguish convenient.Its insulation adopts casting epoxy resin material, has good electric insulating effect.At metal cabinet inner surface and bus-bar outer surface semiconductive material, further mitigation electric field, metal cabinet and inner surface semi-conductive layer play dual grounds function of shielding, it is ensured that the safety of use.In the both sides of cable-joint protector box, it is additionally provided with the fixing bolt of installation, is convenient to install and fixes.Three single-phase connector boxs are mounted side by side and are the formation of one group of three-phase branch joint connector box together.This connector box can form three branches, four branches or more easily when making.
The present invention specifically applies as it is shown on figure 3, interpolation type terminal hole and outside plug type terminal can be connected with elbow-type head respectively through single path sleeve joint, and bus-bar two ends are fixed with T connector respectively through bolt, can connect stress cone and insulating plug respectively by T connector.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to make some improvement, and these improvement also should be regarded as protection scope of the present invention.
