Description
Technical field
This utility model relates to power cable field, 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, constructing and install all inconvenient, often resulting in cable accessory damage, service life declines to a great extent, and all brings unnecessary trouble to user and maintenance；If cable branch box body needs to take larger area soil, then economical and the most unsatisfactory.
Utility model content
Technical problem to be solved in the utility model 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 be at various environment life-time service.
This utility model includes that inside has bus-bar, interpolation type terminal hole and the metal cabinet of 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, described metal cabinet inner surface to be 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.
This utility model 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 the highest 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 resilient cable plug formula terminal, form again optimal connection combination, make connection very reliable, be not required to safeguard after longtime running.
3, cable connector is on same cable-joint protector box, and volume is the least, simultaneously, branch bus-bar multiple interpolation type terminal 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 to be installed and the requirement of various bifurcation approach, installation method simple possible in the confined space, and erector is manually not required to special training.
5, product has separability, changes simplicity, and in once running, cable or cable plug formula terminal break down, as long as pulling up failure cable to change cable in stock, time saving and energy saving, shorten emergency repair time.

Fig. 1 is this utility model front view.
Fig. 2 is this utility model side view.
Fig. 3 is this utility model application schematic diagram.
Detailed description of the invention
This utility model structure 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, described metal cabinet 1 inner surface to be 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 this utility model manufactures, at metal cabinet inner surface insulation screen, then it is inserted into conductor at metal cabinet, after reserved good jack, in metal cabinet, pours resin insulating barrier.
This utility model by cable connector on same cable-joint protector box, volume is the least, simultaneously, branch bus-bar multiple interpolation type terminal 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 uses 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.
This utility model is specifically applied as it is shown on figure 3, interpolation type terminal hole and outside plug type terminal can be connected with elbow-type head by single path sleeve joint respectively, and bus-bar two ends have been bolted T connector respectively, can connect stress cone and insulating plug respectively by T connector.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvement, these improvement also should be regarded as protection domain of the present utility model.
