Abstract
The invention discloses a null line post head of a house-entrance fuse box. The null line post head of the house-entrance fuse box is connected with an inlet wire and an outlet wire and comprises a conducting rod and two locking nuts. Two fixing holes are formed in a rod body of the conducting rod, and the two ends of the conducting rod are respectively provided with a screw hole, and the inlet wire and the outlet wire are fastened in the screw holes in the two ends of the conducting rod by the locking nuts. The null line post head of the house-entrance fuse box has the advantages of being good in electrical conductivity, antirust and convenient to mount. Meanwhile, a lead wire and a null line bar are good in connection, large in contact area, good in reliability, minimal in contact resistance and small in temperature rising compared with null line bars with the same cross section.
Description
Technical field
The present invention relates to a kind of zero line pile crown for house lead in fuse box.
Background technology
The at present ununified standard of zero line pile crown, 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 object of the present invention is to provide a kind of zero line pile crown, have good conductivity, antirust, convenient feature of installing, 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 invention has the beneficial effects as follows: the present invention is made up of copper H62, and at electroplate, thus antirust and there is 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.

Fig. 2 is the end view of house lead in fuse box zero line pile crown of the present invention;
Fig. 3 is the profile of locking nut in the present invention;
Fig. 4 is the vertical view of Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, house lead in fuse box zero line pile crown of the present invention, 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, has two fixing holes 11 in the female parts of shaft, and meanwhile, two of conducting rod 1 is respectively equipped with a screw 12;
For by fastening line 3 crimping, locking nut 2 designs are as follows:
Offer one at locking nut 2 centers for penetrating the perforation of line 3, be divided into along this perforation outer wall locking nut 2 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 used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
