Abstract
The utility model discloses a 0.4kV low-voltage indoor crimping type connecting clamp and relates to the wire connecting device field. The 0.4kV low-voltage indoor crimping type connecting clamp comprises a conductive sleeve; the outer surface of the conductive sleeve is coated with an outer insulating layer; and the conductive sleeve is composed of a plurality of conductive branch tubes which are connected with one another and are hollow inside. According to the 0.4kV low-voltage indoor crimping type connecting clamp of the utility model, an originally-adopted winding technique is converted into a crimping technique, and therefore, the connection of wires at each connection point is more stable, and use can be simpler, and operation is convenient, and low-voltage indoor wiring can be accomplished quickly; and with the special thermally-shrinkable insulation sleeve adopted, a hidden risk of insulation reduction of the connecting clamp after crimping can be eliminated.
Description
Technical field
The utility model relates to wire connection device field.
Background technology
In electric power system, when 0.4kV low pressure interior wiring, often need to connect the wire at low-voltage line tie point place.What in traditional Wiring technique, conventionally adopt for low-voltage line tie point is canoe, although manufacture craft is simple, but, operation duration, and be often wound around a some loose contact and cause that wire is overheated or insulating barrier is damaged because misoperation causes, even cause the generation of the dangerous situations such as electric shock, fire.
Utility model content
Technical problem to be solved in the utility model is to provide the indoor crimp type connecting clamp of a kind of 0.4kV low pressure, makes the wiring of wire tie point firm firm, and using method is simple, easy to operate, can make low pressure interior wiring complete fast.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the indoor crimp type connecting clamp of 0.4kV low pressure, comprise conductive casings, described conductive casings outer surface is coated with external insulation layer, conductive casings by some link together and inside in logical conduction arm form.
Further technical scheme, is connected with solid bonding conductor in described conductive casings, described solid bonding conductor is made up of with the conduction support body that conduction arm equates quantity, and the external diameter of support body of conducting electricity equals to conduct electricity the internal diameter of arm.
Further technical scheme, also comprises pyrocondensation insulated tube, and pyrocondensation insulated tube is coated on conduction arm and wire-protecting interlayer.
Further technical scheme, the conduction arm quantity on described conductive casings is greater than 2.
The beneficial effect that adopts technique scheme to produce is: the utility model changes the winding process originally using into compression joint technique, make each tie point wire connect more firm, using method is simple, easy to operate, can make low pressure interior wiring complete fast.By the special pyrocondensation insulating sleeve being equipped with, solved the hidden danger that may cause connecting clamp insulation to decline after crimping simultaneously.

Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model use principle figure;
In the accompanying drawings: 1, solid bonding conductor, 2, conductive casings, 3, external insulation layer, 4, conductor protective layer, 5, wire heart yearn, 6, pyrocondensation insulated tube, 7, conduction support body, 8, conduction arm.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the indoor crimp type connecting clamp of 0.4kV low pressure, comprise conductive casings 2, described conductive casings 2 outer surfaces are coated with external insulation layer 3, external insulation layer 3 is mainly used for integral insulation of the present utility model, conductive casings 2 link together by 3 and inside in logical conduction arm 8 form, conduction arm 8 is mainly used in carrying out crimping with wire and is connected.In described conductive casings 2, be connected with solid bonding conductor 1, described solid bonding conductor 1 is made up of 3 conduction support bodies 7, and conduction support body 7 is mainly used in carrying out integrated connection with conductive casings 2, and the external diameter of conduction support body 7 equals to conduct electricity the internal diameter of arm 8.Also comprise pyrocondensation insulated tube 6, be mainly used in being connected of the utility model and wire, and ensure tie point and external insulation, as shown in Figure 2, pyrocondensation insulated tube 6 is coated between conduction arm 8 and conductor protective layer 4.The utility model can be made according to the difference of the quantity of low-voltage line tie point place wire, wire heart yearn 5 wire diameters.
Using method of the present utility model is: first, by the conductor protective layer 4 of the wire stripping certain length of required connection, only leave wire heart yearn 5, then wire heart yearn 5 is inserted respectively to 8 li of conduction arms corresponding in the utility model; Then, utilize Press Plier that conductive casings 2 and 5 crimping of wire heart yearn are integrated; Finally, use pyrocondensation insulated tube 6 to cover, and the length of pyrocondensation insulated tube 6 contains one end of wire heart yearn 5 and solid bonding conductor 1, and use heat gun heating, pyrocondensation insulated tube 6 is fitted completely, can complete wire and connect.
The beneficial effects of the utility model are: the utility model by originally use winding process change compression joint technique into, make each tie point wire connect more firm, using method is simple, easy to operate, can make low pressure interior wiring complete fast.By the special pyrocondensation insulated tube 6 being equipped with, solved the hidden danger that may cause connecting clamp insulation to decline after crimping simultaneously.
