Abstract
The utility model discloses a null line connecting joint comprising a wiring plate. An arc-shaped card slot is arranged at each of two ends of the wiring plate; a fixing seat is arranged in the middle of the wiring plate and an axial tapered hole is formed in the fixing seat; a tapered pin is arranged in the tapered hole and a thread section is arranged at the lower end of the tapered pin; a nut is threaded on the thread section; two radial through holes are formed on the fixing seat in a penetrating manner; the through holes are communicated with the tapered hole; and each through hole is internally provided with an arc-shaped wire pressing plate. The null line connecting joint disclosed by the utility model changes the traditional wiring manner and a wiring clip structure so that the reliability of null line contact is improved, the zero breaking possibility is reduced and a large quantity of equipment is prevented from being burnt.
Description
One. technical field: the utility model relates to a kind of power line joint, particularly relates to a kind of zero line jointing.
Two. background technology: in supply line; Cause disconnected zero factor a lot, wherein cause loose contact and then burn binding post to account for main cause, the easy oxidation of present normally used mode of connection center line nose because of the binding clip appearance at zero line two ends is loosening; Cause loosening heating; Burn bolt and nut, and then blow zero line, thereby the equipment of this phase is burnt in a large number.
Three. the utility model content:
The utility model technical problem to be solved is: overcome the deficiency of prior art, provide a kind of reasonable in design, be connected firmly and zero line jointing that disconnected zero probability is little.
The technical scheme of the utility model is: a kind of zero line jointing, contain terminal block, and said terminal block two ends are provided with an arc cable clamping interface respectively; A holder is set in the middle of the said terminal block; Said holder is provided with axial taper hole, is provided with taper pin in the said taper hole, and said taper pin lower end is provided with thread segment; Be combined with nut on this thread segment; Run through said holder and be provided with two through holes radially, said through hole and said taper hole connect each other, and an arc tension disc all is set in each said through hole.
Said arc tension disc is formed by connecting arc and depression bar, and said arc front end is corresponding with said arc cable clamping interface, and said depression bar rear end is inserted in the said through hole and with said taper pin and contacts.Said depression bar rear end face is an arc.
The beneficial effect of the utility model is:
1, the utility model has changed traditional mode of connection and joint design, has improved the reliability of zero line contact, reduces disconnected zero probability, and the equipment of stopping burns in a large number, and social benefit is good.
2, the utility model adopts the mode that taper pin compresses, and zero line is connected firmly, and through the adjustment nut, can strain taper pin, and is easy to operate.
3, the utility model reasonable in design, be connected firmly and disconnected zero probability little, be easy to promote, have good economic benefit.
Four. description of drawings:
Fig. 1 is the structural representation of zero line jointing;
Fig. 2 is the vertical view of zero line jointing shown in Figure 1.
Five. embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, among the figure, 1-zero line, 2-arc tension disc, 3-holder, 4-taper pin, 5-connecting plate, 6-binding post.
The zero line jointing contains terminal block 5, and terminal block 5 two ends are provided with an arc cable clamping interface respectively, and a holder 3 is set in the middle of the terminal block 5; Holder 3 is provided with axial taper hole, is provided with taper pin 4 in the taper hole, and taper pin 4 lower ends are provided with thread segment; Be combined with nut on this thread segment; Run through holder 3 and be provided with two through holes radially, through hole and taper hole connect each other, and an arc tension disc 2 all is set in each through hole.
During use, unclamp 4, two depression bars of taper pin and all stretch in through hole and the taper hole, in two arc cable clamping interfaces, snap in zero line 1 and binding post 6 respectively, insert taper pin 4, taper pin 4 promotes depression bar and outwards moves, and impels arc to compress zero line 1 and binding post 6.When wiring was loosening, it was descending to spur taper pin 4 through the nut of screwing, and just can better compress zero line 1 and binding post 6 respectively.
