Abstract
The utility model discloses a zero line pile head of a house-service fuse box, which is used for being connected with an incoming line and an outgoing line. The zero line pile head of a house-service fuse box comprises a conductive rod and two locking nuts; the rod body of the conductive rod is provided with two fixing holes and two heads of the conductive rod are respectively provided with a screw hole; and the locking nuts fasten the incoming line and the outgoing line inside the screw holes at two heads of the conductive rod. The zero line pile head of a house-service fuse box is good in conductive performance, antirust and convenient in installation; and connection between the wire and a zero bar is good, the contact area is large, reliability is good, contact resistance is small, and the temperature rise is smaller compared with the zero bar with the same cross section.
Description
Technical field
The utility model relates to a kind of zero line pile crown for house lead in fuse box.
Background technology
At present zero line pile crown does not have unified standard, installs lack of standardizationly, and fuse box is more old-fashioned, narrow space, wiring are more in disorder.Because joint is more, the zero line pile crown situation of burning occurring due to the place's loose contact of zero line pile crown in actual use happens occasionally, and the voltage deviation of generation can cause resident's electrical equipment to damage, and gets rusty easily.For this situation, for guaranteeing the safety of house lead in fuse box in distribution running, effectively reduce failure rate, for resident's safety utilization of electric power provides reliable support.Developing a kind of zero line and connect that fastness is strong, anti-gets rusty, can simplify the zero line pile crown that mounting process is increased work efficiency, is that the applicant is devoted to the direction of making great efforts.
Summary of the invention
The purpose of this utility model is to provide a kind of zero line pile crown, has good conductivity, antirust, convenient feature of installing, and meanwhile, wire and zero-emission connect good, and contact area is large, and reliability is good, and contact resistance is minimum, less with the specific temperature rise of same cross section zero-emission phase.
The technical scheme that realizes above-mentioned purpose is:
A zero line pile crown for house lead in fuse box, connects line, comprises conducting rod and two locking nuts, wherein:
The shaft of described conducting rod has two fixing holes, and two of this conducting rod is respectively equipped with a screw;
Described locking nut is anchored on described line in the screw at described conducting rod two.
In the zero line pile crown of above-mentioned house lead in fuse box, described locking nut center has one for penetrating the perforation of described line, and described locking nut comprises nut portion, threaded portion and tight oral area that internal diameter successively decreases successively.
In the zero line pile crown of above-mentioned house lead in fuse box, the side of described tight oral area is the inclined-plane successively tightening.
In the zero line pile crown of above-mentioned house lead in fuse box, the periphery of described nut portion is hexagon.
In the zero line pile crown of above-mentioned house lead in fuse box, described screw internal diameter from outside to inside agrees with the threaded portion of described locking nut and the internal diameter of tight oral area successively.
In the zero line pile crown of above-mentioned house lead in fuse box, the material of described conducting rod and two locking nuts is copper H62.
In the zero line pile crown of above-mentioned house lead in fuse box, the surface of described conducting rod and two locking nuts is all silver-plated.
The beneficial effects of the utility model are: the utility model is made by copper H62, and at electroplate, thereby antirust and have a better electric conductivity.Meanwhile, by the locking nut successively tightening, wire and zero-emission are connect good, contact area is large, and reliability is good, and contact resistance is minimum, less with the specific temperature rise of same cross section zero-emission phase.And nut is arranged to hexagon, can simplifies mounting process and increase work efficiency, thereby effectively reduce failure rate, for resident's safety utilization of electric power provides reliable support.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, house lead in fuse box zero line pile crown of the present utility model, comprises conducting rod 1 and two locking nuts 2, wherein:
The shaft part indent of conducting rod 1, is the form of two circle middle flat, in the female parts of shaft, has two fixing holes 11, and meanwhile, two of conducting rod 1 is respectively equipped with a screw 12;
Locking nut 2 is for being fixed in line tight 3 in the screw 12 at conducting rod 1 two; In the present embodiment, the material of conducting rod 1 and two locking nuts 2 is copper H62, use for a long time non-corrosive, not silk tooth; The electroplate of conducting rod 1 and two locking nuts 2, makes electric conductivity more good;
For line 3 crimping are fastening, locking nut 2 designs are as follows:
At locking nut 2 centers, offer one for penetrating the perforation of line 3, along this perforation outer wall locking nut 2, be divided into nut portion 21, threaded portion 22 and the tight oral area 23 that internal diameter successively decreases successively, wherein,
The side of tight oral area 23 is the inclined-plane successively tightening, and is of value to line 3 is compressed, and line 3 and zero-emission is connect good, and contact area is large, and reliability is good, and contact resistance is minimum, little a lot of with other zero-emission phase specific temperature rises of same cross section.
The periphery of nut portion 21 is hexagon, adds the design of fixing hole 11, can simplify mounting process and increase work efficiency.For locking nut 2, screw 12 internal diameter from outside to inside agrees with mutually with the threaded portion 22 of locking nut 2 and the internal diameter of tight oral area 23 successively.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that not departing from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
