Abstract
The invention provides a cable connector using an insulation-piercing mode to connect cables, the connector body is manufactured by using aluminum casting alloy and is externally coated with an insulating layer, the connector body comprises a main connecting body, a clamping body is connected on the main connecting body by connecting bolts, clamped innerarc surfaces are arranged at the positions where the main connecting body and the clamping body are contacted with cables and are intensively provided with clamped prickling pins which are casted and shaped at the same time with the main connecting body and the clamping body, the main connecting body is provided with a threaded mounting hole, the clamping body is provided with a fan-shaped connecting hole, the outer side of the clamping body is arranged in an arch shape, and the connecting pressure of the connector is undertaken by the aluminum alloy body. The invention has the advantages that the clamped prickling pins are sued to pierce the cable insulating layer and be communicated with a conductor on the premise of not stripping off the cable insulating layer, so that cables can be connected rapidly and effectively. The invention has the advantages of strong anti-overloading capacity, good copper-aluminum transition performance and favorable reducing joint performance.
Description
Technical field:
The invention belongs to electric power stringing gold utensil field, is the connection gold utensil of outdoor aerial cable or indoor power wiring.
Background technology:
The existing power overhead network cable or wires that insulating protective layer is arranged that adopt more, indoor distribution also adopts the cable of insulated hull, traditional installation branch cable mode need be peelled off insulated hull, adopt the parallel groove clamp crimping, the easy oxidation of contact causes contact resistance progressively to increase, temperature rise improves constantly, need unscheduled maintenance, the seventies in last century, take the lead in adopting insulation-piercing stube cable technology abroad, not only easy construction, not oxidation of contact has brought good long-term current-carrying runnability and non-maintaining, the product that this technology is made---insulation puncture line clamping enters China also nearly 15 years, and one section general use was arranged on the low-voltage overhead line road, through operation practice after a while, on this product structure, on the control principle and the defective on the material come out gradually, and form certain accident, have influence on universal.
One, anti-overload ability is poor
Insulation puncture line clamping adopts embedded with metal stab knife chip architecture in the plastic casing, though obtain the corresponding insulation level, but bigger connection pressure passes through the plastic casing localized delivery to the puncture blade, case material intensity is proposed very high request, when higher lead temperature rise (overload) was delivered to housing by the puncture blade, thermal deformation took place in housing under the effect of connection pressure, cause connecting pressure and reduce, contact resistance increases and moltenly falls, and the molten point of case material low (180 ℃) is a main cause.
Two, connection pressure dispersiveness is bigger than normal
Insulation puncture line clamping adopts torque nut that the control principle of constant force is provided, purpose is that a reliable contact pressure is arranged when guaranteeing installation, that does not sting again simultaneously injures conductor intensity too deeply, the cable insulation temperature influence, firmness change is bigger, when installing under the lower temperature, the connection pressure that twists off the torque nut acquisition is not nearly enough, cause and virtually connect and the workmen can not intuitively find, it is big as moment is transferred, installation can injure conductor intensity again under the higher temperature, and the constant contact pressure that this product provides and the contradiction of inconstant wire insulation hardness can not adapt to the torque nut scheme by sample.
Three, environmental resistance is poor
Insulation puncture line clamping adopts Reinforced Nylon 66 to do case material, this material has very high intensity and toughness, has water absorption character simultaneously, be in for a long time drench with rain or humidity than the insulation puncture line clamping that moves in the overall situation, can descend because of suction causes casing rigidity, connect laxly and molten to fall.
Summary of the invention:
The purpose of this invention is to provide a kind of installation at various temperatures, conductor can both obtain the contact pressure and the controllable degree of depth of thrusting about equally, anti-overload ability is strong, it is strong than the heavy insulation ability more firmly to puncture, the mechanical strength height, the cable connector that environmental resistance is good all has installation capability preferably to the cable in collinear footpath not simultaneously.
The objective of the invention is to be achieved through the following technical solutions, adopt molten point high (670 ℃) intensity height, resistivity is low, corrosion resistant almag, the compression casting connector body, connector body comprises main connector, connect the clamping body by connecting bolt on the main connector, at main connector, clamping body and cable position contacting are provided with the clamping intrados, clamp intensive the setting with main connector on the intrados, the clamping body is the contour prickle needle of casting simultaneously, the prickle needle height is that conductor degree of depth sum is thrust in thickness of insulating layer and setting, and vertical installation screwed hole is set on the main connector, and the connecting hole on the clamping body is fan-shaped setting, it is when connecting for not collinear footpath that the outside is the cambered surface setting, connecting bolt has swing a hole and vertical hard point, and connector adopts external application insulating barrier and protective cover setting, and aluminum alloy body is born connection pressure.
Description of drawings:
Fig. 1 is a structural representation of the present invention, illustrates the clamping body structure emphatically.
Fig. 2 is the section of structure of the present invention when not collinear footpath cable is installed.
Fig. 3 is the present invention's aluminium alloy connector main body structure schematic diagram when not applying insulating barrier.
Embodiment
See to be provided with on the main connector 1 of Fig. 1-3 and clamp intrados 2,3, clamp on the intrados prickle needle 6 is set, vertical threaded mounting hole 7 is set on the main connector, be provided with on the clamping body 8 and clamp intrados 4,5, clamp on the intrados prickle needle 6 is set, fan-shaped installing hole 9 on the clamping body, outside cambered surface 10, connecting bolt 11, main connector external application insulating barrier 12, the external deposited insulating barrier 13 of clamping, protective cover 14 is installed the cross-section of cable 15,16.
During use, the cable 15,16 that will have insulated hull, place in the clamping intrados 2,3,4,5 of main connector 1 and clamping body 8, progressively tighten connecting bolt 11, when prickle needle 6 thrusts and thrusts conductor behind the cable insulation and preestablish the degree of depth, the insulating barrier large tracts of land contact and forms with clamping intrados 2,3,4,5 that resistance is spacing greatly, finishes connection when connecting bolt 11 is stubborn when motionless, covers protective cover 14.
Claims (1)
1. cable connector with the insulation-piercing mode stube cable, it is to adopt the Birmasil mode to make connector body, the cable connector of main body external application insulating barrier, connector body comprises main connector, connect the clamping body by connecting bolt on the main connector, at main connector, clamping body and cable position contacting are provided with the clamping intrados, clamp intensive setting and main connector on the intrados, the clamping body is the prickle needle of casting simultaneously, vertical threaded mounting hole is set on the main connector, fan-shaped connecting hole is set on the clamping body, and the external side of clamping is the cambered surface setting, and the connection pressure of connector is born by aluminum alloy body.
