Abstract
The utility model relates to a detachable special parallel channel cable grip. The cables or the steel cables are fastened through bolts. The utility model comprises an upper clamping block (2), a lower fixture block (1), a clip spacer (3), screw bolts (5) and a cushion ring (4), wherein, wire grooves (8), (9) are respectively arranged on the both sides of the vertical center line of the cross section of the upper and lower clamping blocks; along the longitudinal centerline of the upper and lower clamping blocks, ellipse-shaped taper holes (7) which are extended towards the two-blade direction are perpendicular to the upper clamping block, and threaded holes (10) are perpendicular to the lower clamping block (1); the upper top of the clip spacer (3) is a plane, and the lower base is a cambered surface which is fit close with the top face of the upper clamping block; at least one through-hole (6) is opened on the longitudinal axle; the cables or the steel cables can be fixedly and rapidly fastened by utilizing screw bolt components.
Description
The utility model belongs to the wire clamp head that power cable that electric power transmission uses or cable wire connect usefulness.
The supply district of general electric power transmission network is all very wide, and electric transmission line is longer, the power cable of finite length must be connected with each other.Current at present connecting means: be to adopt single tenminal block (as DT, DL tenminal block) to be connected the power cable core as the local crimping method in termination with DTL series, or the connecting tube that adopts GT, GL, GLT series is connected in series the power cable core mutually as local crimping method.
There is following shortcoming in such connecting method: the crimping tool that needs are special-purpose; The diameter of power cable must conform to the aperture of tenminal block or connecting pipe; Can only singlely be connected in series; Be a kind of nonvolatil connection, can not separate, can not demolition.
The purpose of this utility model is for easy, rapidly and reliably will be with the power cable core or the cable wire polyphone of footpath or reducing, and connect and corner connection provides a kind of bolted detachable type abnormal shape parallel groove clamp together.
Special-shaped parallel groove clamp of the present utility model, realize by the following technical solutions, power cable core or cable wire with to be connected are clamped in by excellent conductivity with bolt assembly, and two cross sections making matrix of the metallic material with higher-strength are between the special-shaped fixture block.Special-shaped parallel groove clamp of the present utility model is by last fixture block (2), following fixture block (1), and wire clamp pad (3) and the bolt (5) that connects the three constitute with packing ring (4); It is special-shaped that the cross section of last fixture block (2) and following fixture block (1) is, and respectively is provided with wire casing (8) and (9) of arc section in the vertical center line y both sides of the block cross section of last fixture block (2) and following fixture block (1), and groove face can be carved with profile of tooth T; Along on the vertical center line Z of last fixture block (2) and following fixture block (1), have the long-round-shape taper hole (7) that stretches to the both wings direction perpendicular to last fixture block (2), have tapped hole (10) perpendicular to following fixture block (1); The end face of wire clamp pad (3) is a plane P, and bottom surface is the cambered surface c that coincide with last fixture block (2) end face B, has a through hole (6) on its longitudinal axis Z at least, has V font breach V on two sides between the hole.
The core of power cable or cable wire are lain in the wire casing (8) and (9) of fixture block (2) and play fixture block (1), the long-round-shape taper hole (7) that bolt (5) passes packing ring (4) wire clamp pad (3) and last fixture block (2) screws in the tapped hole (10) of following fixture block (1), until power cable core or cable wire are clamped.
The vertical center line Z of following fixture block (1) is provided with at least one tapped hole (10), have only a long-round-shape taper hole (7) on the vertical center line Z of last fixture block (2), therefore a following fixture block (1) have at least one or a plurality of go up fixture block (2) (look down fixture block (1) tapped hole (10) quantity and decide) match with it.
For satisfying the performance requirement that is electrically connected that copper aluminium links, can locate in former wire casing (8) and (9) to inlay with last fixture block (2) and following fixture block (1) and connect, the copper that has the curved trunking in cross section insert (11) with dovetail groove type S falcon.
Special-shaped parallel groove clamp of the present utility model: owing to be provided with the cross section of band profile of tooth T is wire casing (8) and (9) of arc, and last fixture block (2) has long-round-shape taper hole (7), so can on certain degree, adapt to the deviation of power cable core or rope diameter and shape, also can clamp the line footpath of different-diameter simultaneously; Owing to be provided with more than one upward fixture block (2), so special-shaped parallel groove clamp of the present utility model both power cable core or cable wire with diameter and different-diameter can be contacted, and link up, but also cross connects, the T word connects.Both supporting wrench of available dedicated during connection, also available Allen wrench.
Fig. 1 is a typical shaft mapping of fixture block (1) under the special-shaped parallel groove clamp of the present utility model.
Fig. 2 is the structural drawing of special-shaped parallel groove clamp of the present utility model.
Fig. 3 is a kind of special-shaped parallel groove clamp that has copper aluminium crossover sub of the present utility model.
Fig. 4 is the typical shaft mapping that has the wire clamp pad (3) of a plurality of through holes (6) in the utility model.
Be elaborated below in conjunction with the exemplary embodiments of accompanying drawing to special-shaped parallel groove clamp of the present utility model:
Special-shaped parallel groove clamp is by last fixture block (2), following fixture block (1).Wire clamp pad (3) and connection three's bolt (5) constitutes with packing ring (4); The cross section of last fixture block (2) and following fixture block (1) is abnormity, respectively is provided with wire casing (8) and (9) of arc section in the vertical center line Y both sides of the block cross section of last fixture block (2) and following fixture block (1), and groove face can be carved with profile of tooth T; Along on the vertical center line Z of last fixture block (2) and following fixture block (1), have the long-round-shape taper hole (7) that stretches to the both wings direction perpendicular to last fixture block (2), have tapped hole (10) perpendicular to following fixture block (1); The last end face of wire clamp pad (3) is a plane P, and bottom surface is the cambered surface C that coincide with last fixture block (2) end face B, has a through hole (6) on its longitudinal axis Z at least, has V-shape breach V on two sides between the hole.
