Abstract
The utility model provides a cutting ferrule type cable fastener device, this fastener device include fastener body, interior cutting ferrule, outer cutting ferrule, lock nut, it is inboard that fastener body cavity is located to interior cutting ferrule, the outside of cutting ferrule including the wild card ways, and interior cutting ferrule is mutually supported through the conical surface with outer cutting ferrule between the two, lock nut revolves with the fastener body and twists the joint, closes the in -process soon, and lock nut promotes outer cutting ferrule and pushes interior cutting ferrule inwards, cutting ferrule internal diameter shrink in making. The utility model discloses it is poor that the effect is that the anti -soil ability of open architecture's bolt fastener has been solved to this fastener device, because resistance increase and the problem of the accident potential that leads to. It is little with the power of holding also to have solved crimping formula fastener, can not be used for great diameter cable, and is the disposable problem. This fastener is easy and simple to handle, and repeatedly usable is applicable to the cable of different sectional areas. Compact structure is simple for this fastener device, the dependable performance, and especially adapted internal various electrical power transmission/distribution system, the environment that especially current internal air pollution is more serious uses down.
Description
Technical field
The utility model relates to a kind of bite type cable clamp device, can be used for electric power cable and plain conductor and various power transmission and transforming equipment, controller switching equipment to be fastenedly connected reliably, also may be used for connecting of the conductive bus bar of power cable and various equipment.
Background technology
In at present power transmission and transformation at home, distribution system, the connection of various power equipment and conductor cable generally adopts cable clamp.And domestic widely used cable clamp is mainly divided into bolted and compression joint type two kinds.Bolted wire clamp is open architecture, its structure is simple, but in order to ensure that blessing power uses bolt more, and cable and wire clamp junction wire expose, therefore this kind of wire clamp anti-soil resistance to corrosion is poor, the contact resistance after long-time use between wire clamp and cable increases, and causes heating serious, line loss strengthens, and even can cause wire clamp fusing accident.Compression joint type wire clamp is closed type structure, easy to use, and antipollution resistance to corrosion is better, but needs when using to use special aid.This kind of wire clamp is little to the blessing power of cable, therefore it is less and use by the cable that pulling force is little to be only applicable to wire diameter, mostly is single use.
Summary of the invention
The utility model provides a kind of bite type cable clamp device, be beneficial to solve the problem that cable in current bolted cable clamp structure is directly exposed to antipollution in air, oxidation resistance difference Long-Time Service conductive resistance increases, and the problem of compression joint type wire clamp narrow application range.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of bite type cable clamp device, wherein: this line clamping device comprises wire clip body, interior cutting ferrule, outer cutting ferrule, locking nut, described interior cutting ferrule is located at inside wire clip body cavity, outer cutting ferrule is enclosed within the outside of interior cutting ferrule, and interior cutting ferrule and outer cutting ferrule are cooperatively interacted by the conical surface between the two; Locking nut and wire clip body screw joint, screw in process, and locking nut promotes outer cutting ferrule and extrudes interior cutting ferrule inwards, and interior cutting ferrule internal diameter is shunk.
It is poor that the utility model effect is that this line clamping device solves the stain resistance of the bolt wire clamp of open architecture, the problem of the accident potential that Long-Time Service causes wire clamp and conductive cable contacts surface resistance to increase and cause.Also solve compression joint type wire clamp simultaneously and accommodate power not quite, by specific purpose tool, need can not be used for larger diameter cable during use, and be disposable problem.This wire clamp only needs two spanners to operate when installing, and can reuse simultaneously.Wire clip body coordinates the inside and outside cutting ferrule body of different size, is applicable to the cable of different cross-sectional.This line clamping device compact conformation is simple, easy to operate, dependable performance, is very applicable to domestic various electrical power trans mission/distribution systems, uses under the environment that particularly Present Domestic air pollution is more serious.

Embodiment
By reference to the accompanying drawings bite type cable clamp apparatus structure of the present utility model is illustrated.
Bite type cable clamp apparatus design thought of the present utility model is that interior cutting ferrule, outer cutting ferrule, locking nut are fixed with it by main body with wire clip body, by the threaded engagement on locking nut and wire clip body, locking nut is screwed with spanner, outer cutting ferrule can be promoted move to wire clip body, thus wild card cover inwardly promotes further and extrudes interior cutting ferrule, makes inside and outside cutting ferrule hold filled cable tightly and fixing object simultaneously.
As Figure 1-4, bite type cable clamp device of the present utility model, this line clamping device comprises wire clip body 1, interior cutting ferrule 2, outer cutting ferrule 3, locking nut 4, described interior cutting ferrule 2 is located at inside wire clip body 1 cavity, outer cutting ferrule 3 is enclosed within the outside of interior cutting ferrule 2, and interior cutting ferrule 2 is cooperatively interacted by the conical surface between the two with outer cutting ferrule 3; Locking nut 4 and wire clip body 1 screw joint, screw in process, and locking nut 4 promotes outer cutting ferrule 3 and extrudes interior cutting ferrule 2 inwards, and interior cutting ferrule 2 internal diameter is shunk.
Described wire clip body 1 cylindrical end is divided into external thread structure, its inside is the taper hole cavity of cone angle 6 degree, interior cutting ferrule 2 outer surface is made up of former and later two conical surfaces, inner cone length is greater than rear cone, inner cone cone angle is 6 degree, rear cone cone angle is 12 degree, and interior cutting ferrule 2 is two parts of split type upper and lower fastening, described two-part inwall is equipped with 4 to 5 annular dentations; Outer cutting ferrule 3 is a tubular body, and tubular body inwall first half is the inner conical surface matched with interior cutting ferrule 2 rear cone, and latter half is through hole.
Use bite type cable clamp device operating procedure of the present utility model:
First cable end face is neatly cut, afterwards locking nut 4 is oppositely penetrated, outer cutting ferrule 3 is oppositely penetrated, then with interior cutting ferrule 2, the installation end of cable is embraced, cable end face should give prominence to interior cutting ferrule about 5 millimeters, and cable is loaded together the cone-shaped inner hole of wire clip body 1 with interior cutting ferrule 2.Locking nut 4 is screwed on wire clip body 1, namely complete the prepackage of this device.
When locking nut 4 screws with wire clip body 1, the interior hole end surface of locking nut 4 promotes outer cutting ferrule 3 and moves vertically, and in promoting, cutting ferrule 2 moves vertically.Because the cone-shaped inner hole of wire clip body 1 retrains, while interior cutting ferrule 2 moves axially, internal bore radius shrinks, and cable is by interior cutting ferrule 2 banding, and cable " is stung tightly " in the dentation meeting of its inside, hole.The continuing of locking nut 4 is tightened, and the clamping force of interior cutting ferrule 2 pairs of cables also continues to increase.
Otherwise, oppositely unscrew locking nut 4 cables with spanner and interior cutting ferrule 2, outer cutting ferrule 3 get loose, can cable be unloaded.
