Abstract
The utility model relates to a ring pressing type anti-bracing wire clamp which is characterized in that an outer cone is provided with a deformed groove; the conical surface of the outer cone is oppressed to be deformed by the inner conical surface of a fastening body; as a result, power cables inserted into a slotted cone are fastened. The ring pressing units which exert a clamping force around cables can be combined together agilely and conveniently as required. The other end of each ring pressing unit is provided with a connecting body of which the structure is similar to the structure of the connection of the existing suspension insulator hanging plates. Meanwhile, the ring pressing units provide another clamping force. The ring pressing type anti-bracing wire clamp introduced by the utility model has the characteristics of beautiful appearance, simple and convenient construction, large clamping force and reliable mechanical property.
Description
The utility model is a kind of ring pressure strain clamp, belongs to electric armour clamp.
On the strain tower bar or angle tower bar in overhead power line or the transformer station,, be extensive use of various strain clamps in order to fix or connect the power cable in various cross sections.Prior art generally adopts screw bolt-type or compression-type strain clamp.
Its weak point of screw bolt-type strain clamp is that volume is big, heavy, construction is inconvenient.The compression-type strain clamp then needs special crimping tool, and this makes troubles to site operation.
The purpose of this utility model is, in order to overcome the deficiency of existing strain clamp, and provides a kind of ring pressure strain clamp, in order to connect simply, easily or fixing various power cables.
The said ring pressure strain clamp of the utility model is divided by the ring splenium and coupling part two parts are formed.The ring splenium divides to be made up of clamping body 1 and 2 two parts of fastener.Said clamping body is a bullet that the distortion groove is arranged, and has in the middle of the bullet for the through hole 3 that passes power cable, and periphery is provided with two or more distortion groove 4 vertically, and is provided with male cone (strobilus masculinus) 5 at its outer surface.The garden part is provided with the inner conical surface 6 that matches with the male cone (strobilus masculinus) 5 of clamping body 1 in one end of said fastener 2, and the outer garden part of inner conical surface 6 is provided with external screw thread 7, and the root outer surface of screw thread 7 has for fastening device 8.
The coupling part is that one one end is that garden shape, the other end are foursquare connector 9.One end of garden shape be provided with fastener 2 on the measure-alike internal thread 10 of external screw thread 7, mid portion be provided with the through hole 3 that passes cable ', and vertically through hole 3 ' the position be provided with two the distortion grooves 11, the square end mid portion of connector has and the corresponding to space 12 of suspension insulator link plate thickness, the clamping plate 13 of two symmetries are provided with two groups of through holes, through hole 14 is fastening for fishbolt, in order to clamp through hole 3 ' interior cable, through hole 15 is consistent with the hole on the plate of suspension insulator osmanthus, is connected with the suspension insulator link plate with connecting bolt.
According to the said strain clamp of the utility model, for increasing clamping force, can adopt a plurality of ring splenium branches, the ring splenium that increases divides and aforementioned ring splenium branch difference is, fastener 2 ' fastener 8 ' endoporus position be provided with connector 9 on identical internal thread 10, in order to be connected with external screw thread 7 on other the fastener.Press quantity owing to increased ring, also just increased long-pending that is increased clamping force the ring pressure surface of cable.
According to the said strain clamp of the utility model, the through hole 3 and 3 that can also pass at the middle current supply cable of clamping body 1 and connector 9 ' in the tooth 16 of shape of threads or garden ring-type is set, also can increase clamping force.
Root at aforementioned distortion groove can be the sliding form in arcuation garden, to increase the mechanical strength of clamping body or connector itself.
The using method of strain clamp described in the utility model is as follows:
Cable is inserted in the through hole 3 of clamping body and connector, external screw thread 7 on the fastener 2 is spun mutually with internal thread 10 on the disjunctor 9, the inner conical surface 6 in the dependence fastener 2 and the interaction of the male cone (strobilus masculinus) 5 on the clamping body 1, compressing clamps body deformability, thereby reaches the purpose that clamps the power cable that inserts.On connector 9, pass through hole 14 with fishbolt, binding clip 13 forces intermediate throughholes 3 ' distortion, also can clamp the power cable of insertion.
Power cable pass through hole 3 on the connector ', can be along the space 12 crooked up or down, power supply power cable jumper connection uses.
The strain clamp that the utility model is introduced is fasteningly compared with connected mode with of the prior art, has aesthetic in appearancely, simple and easy to use, and clamping force is big, characteristics such as reliable in mechanical performance, and site operation does not need special crimping tool yet.
Accompanying drawing 1: ring pressure strain clamp
Accompanying drawing 2: have N(N=2,3 ...) strain clamp that divides of individual ring splenium.
Accompanying drawing 3: the structural representation that tooth is arranged in the through hole 3 that current supply cable passes.
Further specify formation of the present utility model below in conjunction with drawings and Examples:
Accompanying drawing 1 divides and the strain clamp that connector is formed for having only a ring splenium, the ring splenium divides to be made up of clamping body 1 and fastener 2, through hole 3 is arranged in the middle of the clamping body 1, outer surface has male cone (strobilus masculinus) 5, periphery is provided with two or more distortion groove 4 vertically, the garden part is provided with the inner conical surface 6 that matches with the male cone (strobilus masculinus) 5 of clamping body 1 in one end of fastener 2, the Wai Yuan position of inner conical surface 6 is provided with external screw thread 7, the outer garden of the root of external screw thread 7 has for fastening device 8, in one end of connector 9 garden be provided with fastener 2 on the measure-alike internal thread 10 of external screw thread 7, mid portion be provided with through hole 3 ', and be provided with at the through hole position vertically two the distortion grooves 11, the other end of connector is a square, the centre has and the corresponding to space 12 of suspension insulator link plate thickness, and the both sides in space 12 are two clamping plates 13 of symmetry, are provided with two groups of through holes thereon, through hole 14 uses for fishbolt, and through hole 15 uses for connecting bolt.
The strain clamp that accompanying drawing 2 divides for the ring splenium with two or more, the places different with accompanying drawing 1 are: the ring splenium branch of increase, its fastener 2 ' on, one end be provided with connector 9 on identical internal thread 10, in order to other fastener on external screw thread 7 spin mutually, this embodiment can provide more ring pressure surface long-pending, thereby bigger clamping force is provided.
The embodiment that accompanying drawing 3 provides is provided with shape of threads or garden ring tooth 16 in the through hole 3 of settling cable, so that bigger clamping force to be provided, this structure can be used among any embodiment.
