According to the he piercing cable clamp, the piercing connection of multiple cables can be achieved at one time through the arrangement of the annular piercing pieces, and the connecting angles between two cables can be set freely.
Description
Technical field
The present invention relates to a kind of fastening means of power circuit, particularly a kind of insulation puncture line clamping.
Background technology
Existing insulation puncture line clamping is mainly by strengthening housing, puncture blade, sealing gasket, waterproof silicone grease, high-strength bolt, torque nut and cable termination cap sleeve composition, when cable Xu Zuo branch or while continuing, cable branch line terminal is inserted to waterproof terminal cap sleeve, determine after main line branch location, with the torque nut on the stubborn wire clamp of box spanner, contactor blade meeting penetrating insulating layer of cable in process, with conductor contact, gasket ring voltage cable is punctured position around, in housing, silicone grease overflows, in the time that moment reaches set point, nut moment explosive separation, main line and branch line are switched on, and water resistance and electric effect have reached the parameter of standard-required.Existing insulation puncture line clamping has following shortcoming: 1) once can only complete the electrical connection of two cables, in the time that multi-cable is electrically connected fast, need to use multiple penetrating cable clamps simultaneously; 2) angle of clamp groove is single, cannot realize arbitrarily angled, neatly multi-cable is connected.
Summary of the invention
In view of this, the problem to be solved in the present invention is to provide a kind of penetrating cable clamp, and this penetrating cable clamp can be realized many cables 360 are spent to electrical connection at any angle, has thoroughly solved the restriction of existing penetrating cable clamp connection cable quantitatively and on setting angle.
Penetrating cable clamp of the present invention, comprise upper shell and lower house, at least one annular thorn sheet is respectively set in described upper shell and lower house, and a side end face of described annular thorn sheet processes puncture tooth, and in described upper shell and lower house, the end face of annular thorn sheet band puncture tooth is oppositely arranged between two up and down; Also comprise the hold down gag that the annular thorn sheet for oppressing in described upper shell and lower house does relative motion.
Further, described hold down gag comprises the screw bolt and nut with the coaxial setting of annular thorn sheet, and described bolts and nuts threaded engagement compresses the annular thorn sheet in upper shell and lower house.Certainly, in specific implementation process, because bolt is generally made up of metallic conductor, therefore consider insulating properties, described screw bolt and nut can not sting sheet with annular and directly contact, for this reason, preferably, the lower surface of the upper surface of upper shell and lower house can be arranged to flatly, and in the outside of the upper surface of upper shell and the lower surface of lower house, a metallic gasket be respectively set, the head of described bolt and nut be contacted with metallic gasket by compressing two housings and indirectly compress two annular thorn sheets.
Further, the back of described annular thorn sheet is provided with annular preform.
Further, the band increment face undulate on described annular thorn sheet.
Further, in described upper shell and lower house, be respectively provided with the annular thorn sheet of two-layer coaxial setting.
Penetrating cable clamp of the present invention, its beneficial effect is:
1) puncture that has realized disposable many cables by annular thorn sheet is set connects.
2) two connection angles between cable can be set arbitrarily.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described.

Embodiment
Below with reference to accompanying drawing, the present invention is described in detail:
As shown in Figures 1 to 4: penetrating cable clamp of the present invention, comprise columniform upper shell 1 and lower house 2, interior at least one the annular thorn sheet 3 that respectively arranges of described upper shell 1 and lower house 2, the upper surface of upper shell and the lower surface of lower house are arranged to flat, the outside of the upper surface of upper shell and the lower surface of lower house respectively arranges a metallic gasket 5, one side end face of described annular thorn sheet 3 processes puncture tooth 31, and the end face of the interior annular thorn of described upper shell 1 and lower house 2 sheet 3 band puncture teeth 31 is oppositely arranged between two up and down; Also comprise the hold down gag that the annular thorn sheet 3 for oppressing in described upper shell 1 and lower house 2 does relative motion, in the present embodiment, described hold down gag comprises bolt 41 and the nut 42 with the coaxial setting of annular thorn sheet 3, described bolt 41 compresses the annular thorn sheet 3 in upper shell 1 and lower house 2 with nut 42 threaded engagement, described bolt 41 can adopt high-strength bolt, the optional torque nut of using of described nut 42.In addition, for ensureing insulating properties, in the present embodiment, described bolt 41 middle parts are also arranged with insulating case 6.Penetrating cable clamp of the present invention has been realized disposable many cables puncture by annular thorn sheet is set connects, and two connection angles between cable can be set arbitrarily, has significant progress and outstanding substantive distinguishing features.In addition, we also can be by the discovery of contrast prior art, and simpler than prior art in penetrating cable clamp structure of the present invention, therefore penetrating cable clamp of the present invention, in the situation that function significantly strengthens, has more reduced manufacturing cost.
As the further improvement of technique scheme, the back 32 of described annular thorn sheet 3 is provided with annular preform 43, described annular preform 43 adopts the ceramic material of metal material or high rigidity to make, for ensureing that the back 32 that annular preform 43 can not stung sheet 3 in annular moves left and right, best, can described upper shell 1 and lower house 2 interior respectively process one can be with annular preform 43 to the groove mating, to hold described annular preform 43, certainly, can the external diameter of the internal diameter of described upper shell 1 and lower house 2 and annular preform 43 be arranged to of the same size, improve the stability of annular preform 43.The object that annular preform 43 is set at the back 32 of annular thorn sheet 3 is the back side bursting that protection housing can not stung by annular sheet.
As the further improvement of technique scheme, the band increment face undulate on described annular thorn sheet 3, can not horizontally slip the cable accommodating between two annular thorn sheets 3.In the time of concrete making, for ensureing that on upper and lower two annular thorn sheets 3, the trough with increment face is always relative, should the position of upper and lower two annular thorn sheets 3 be arranged to relatively-stationary, during the way of its realization has a lot, as respectively offered an axially extended groove in upper and lower two annular thorn corresponding positions of sheet 3, a projection that can be inserted in described groove is respectively set on the inwall of upper shell 1 and lower house 2, by making, between upper shell 1 and lower house 2, relative rotation not to occur, between upper and lower two annular thorn sheets 3, can there is not relative rotation.
As the further improvement of technique scheme, the interior annular thorn sheet 3 that is respectively provided with two-layer coaxial setting of described upper shell 1 and lower house 2, arranges two-layer annular thorn sheet 3 and can improve the dynamics that pulls and supports to cable, prevents cable dropout.In addition, in the present embodiment, two-layer annular thorn sheet 3 is provided with annular cushion block 7, in case stop ring shape thorn sheet 3 is out of shape.
Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
