Description

Insulation puncture line clamping
Technical field
The present invention relates to a kind of insulation puncture line clamping.
Background technology
Insulation puncture line clamping is primarily of upper-lower casing, piercing blade, sealing gasket, waterproof silicone grease, high-strength bolt, nut assembly and cable termination cap sleeve composition, wherein nut assembly comprise match with high-strength bolt for compressing the mother nut of housing and be positioned at the torque nut of mother nut end, be connected by steel ring or plastic ring between torque nut with mother nut, when cable Xu Zuo branch or when continuing, cable branch line terminal is inserted waterproof terminal cap sleeve, after determining main line branch location, the torque nut on wire clamp is twisted with box spanner, by mother nut, upper-lower casing is compressed, contactor blade meeting penetrating insulating layer of cable in the process, with conductor contact, gasket ring voltage cable is punctured around position, in housing, silicone grease overflows, when moment reaches set point, steel ring between torque nut and mother nut or plastic ring are destroyed, thus torque nut is come off, main line and branch line conducting.That is, judge that whether main line and branch line are switched on by coming off of torque nut.Just there is a problem in this, penetrating cable clamp can only single use, and only have replacing nut assembly if will reuse, and the unlike single nut of nut assembly, be nonstandard product, manufacturing cost is high.
For above-mentioned deficiency, need research one reusable and the simple insulation puncture line clamping of structure.
The penetrating cable clamp of a certain model of the prior art is applicable to the cable of certain specification scope, and the penetrating cable clamp being TTD041FJ as model is applicable to main line 6-35mm 2, branch line 1.5-10mm 2but torque nut comes off, required moment is certain, when this will cause same model penetrating cable clamp application different model cable, the degree of piercing blade puncture cable is different, as occurred when being applied to the larger cable of area of section, the degree that pierces through does not have conducting not, and can pierce through when applying the less cable of area of section and deeply cause bottom knife to free collision affecting turn-on effect equally.For this reason, steel wire 42 quantity in same steel wire rack is many, during cable for conducting various cross-sectional areas, when to turn-on effect preferably time, the steel wire rope that number of breaks is different.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is to provide one reusable and the simple insulation puncture line clamping of structure.
Insulation puncture line clamping of the present invention, a kind of insulation puncture line clamping, comprises

Embodiment
Embodiment 1
The insulation puncture line clamping of the present embodiment, comprise upper shell 1 and lower house 2, two first grooves 11 are provided with below upper shell, 12, two second grooves 21 are provided with above corresponding lower house 2, 22, upper shell is provided with piercing blade 13 on two before and after first groove, 14, each upper piercing blade has two knife edge parts, lay respectively in two first grooves, the upper cushion 15 wrapped up by the blade of its inside is provided with in first groove each, 16, equally, lower house is provided with two lower piercing blades 23 before and after second groove, 24, each lower piercing blade has two knife edge parts, lay respectively in two second grooves, the lower cushion 25 wrapped up by the blade of its inside is provided with in second groove each, 26.Form cable trough between the upper and lower cushion of relative position, as above form the cable trough that two can be placed cable respectively between cushion 15 and lower cushion 25 and between upper cushion 16 and lower cushion 26.
Connected by bolt assembly 3 between upper and lower casing, i.e. a bolt 31 passing lower house and upper shell from the bottom to top and the nut 32 be positioned on upper shell matched with bolt.
Unlike the prior art, the present invention arranges torque nut to judge the whether conducting of cable in two cable troughs on nut 32, but pass through at two cable trough arranged outside, two decision mechanisms 4, each decision mechanism 4 comprises steel wire rack 41 and steel wire 42, wherein be connected with lower house 2 bottom steel wire rack 41, steel wire 42 lower end is connected with upper shell, and steel wire 42 upper end is connected with the top of steel wire rack 41.During use, upper-lower casing is opened by adjusting nut position, penetrate in two cable troughs by needing two of conducting with cable, make upper shell close relative to lower house with spanner tightening nut, in the process, steel wire 42 is extended resiliently, the knife edge part of upper and lower piercing blade starts puncture cable insulation and metallic conductor, when seal degree and the piercing blade of upper and lower cushion and metallic conductor contact reach optimum efficiency time, the power that steel wire 42 bears reaches its tensile strength, steel wire fracture, now, main line and branch connect, and water resistance and electrical effects the best.Middle torque nut comes off whether judge conducting from nut assembly compared to existing technology, and use structure of steel wire more simple, manufacturing cost is lower, when reusing, changes steel wire.
Embodiment 2
Decision mechanism 4 is from the different of embodiment 1, described steel wire rack top is provided with clamping part, described steel wire top can be stuck in clamping part and to come off in clamping part after cable conducting, steel wire fracture when comparing cable conducting in embodiment 1, in the present embodiment, clamping part gives steel wire certain clamping force, fastening nut 32, when both sides cable is in best conducting state, the pulling force that steel wire is subject to is enough to overcome its clamping force be subject to thus depart from from clamping part, steel wire can not rupture, steel wire entirety is not damaged, just can reuse without the need to changing steel wire.Preferably, clamping part 5 adopts scroll chuck structure, comprise cutting ferrule 51, be positioned at the intermeshing small bevel gear 52 of cutting ferrule and auger tooth 53 and be positioned at three claws 54 of cutting ferrule end face, described three claw circumferences are uniform, described auger rear flank is provided with into the screw thread that spiral of Archimedes is arranged, described three claws and threaded engagement, small bevel gear drives auger tooth spiral to turn, auger tooth drive three claws simultaneously near or away from its distribution center and then clamping steel wire or unclamp steel wire, by arranging different clamping degrees to be suitable for the cable of various cross-sectional areas.
Such scheme is all indirectly judge the whether conducting of two cables, in order to directly judge whether conducting, the micromachine 6 that operating voltage is 5V is provided with at steel wire rack top, model specifically can be adopted to be the motor of RS-365, be provided with motor switch simultaneously, motor output shaft is connected with small bevel gear, when main line hot line job, the power supply of motor is from wire clamp itself, namely mutual inductor is set around blade, mutual inductor is electrically connected with motor, when after main line and branch line conducting, mutual inductor conduction and by the voltage of photovoltaic conversion needed for motor, now small bevel gear rotates, three claws open, steel wire comes off, judge more direct.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
