Abstract
The utility model discloses a middle connecting structure of a composite insulating tubular cable, which is characterized by comprising an external compaction piece, a connecting conductor, a tubular cable body and an internal compaction piece, which are of hollow tubular structures and are sequentially nested from outside to inside. The structure not only has convenient on-site installation, but also fully ensures the effective contact area because of 360-degree contact.
Description
Technical field
The utility model relates to the syndeton of cable, is specially the 10KV that is used for the power transformation engineering field intermediate connection structure to 35KV electric pressure metallic conduction pipe bus.
Background technology
The connected mode of existing NEW TYPE OF COMPOSITE insulative tubular cable mainly contains two kinds: a kind of is to adopt the fastening mode of metal hood type screw to connect, this connected mode shortcoming is because its stress surface is on a line, cause easily because of unbalance stress causes contact-making surface and cause the too high phenomenon of connector temperature because of unbalance stress can not guarantee effective contact-making surface, on the other hand because the fastening place of screw forms the step of a projection, for the insulation screen of a circle of follow-up formation brings very big difficulty; Another kind is the mode that adopts the on-the-spot welding of metal hood type, this connected mode is held tightly with the instrument crimping at the scene because of both needing, and needs again to weld at the scene, both to on-the-spot welder's specification requirement height, and be difficult to guarantee to overcome the stress of eliminating after compressing after the welding, take a lot of work and time-consuming.
The utility model content
The purpose of this utility model is, overcome the deficiencies in the prior art, provide a kind of 10KV to the high intermediate connection structure that coincide of 35KV NEW TYPE OF COMPOSITE insulative tubular cable, not only on-the-spot easy for installation, and because the comprehensive contact of 360 degree has fully guaranteed effective contact area.
The technical solution of the utility model is achieved in that the intermediate connection structure of compound inslation pipe type cable, comprises outside clamping piece, bonding conductor, pipe type cable body and inner clamping piece, and four are hollow tubular structures, and ecto-entad is nested successively.
As the improvement to such scheme, outside clamping piece, bonding conductor, pipe type cable body and inner clamping piece adopt bolt to be connected.
Concrete, outside clamping piece, bonding conductor, pipe type cable body have circular hole in the same position of same longitudinal section, constitute through hole, inner clamping piece is provided with tooth in same position, holding screw passes through hole and tightens, and makes that outside clamping piece, bonding conductor, pipe type cable body and inner clamping piece are comprehensive to be contacted and tighten together.Described through hole, tooth and holding screw all have six in same longitudinal section, the top of six holding screws constitutes a circular face.
As the improvement to such scheme, outside clamping piece, bonding conductor and inner clamping piece all are to be put together by two semi-round ring shape materials.
The beneficial effects of the utility model are: the circular hole of outside clamping piece, bonding conductor, pipe cable body and inner clamping piece need only be aimed at during on-the-spot the installation, get final product with fastening the going up of holding screw, and very convenient; Because the comprehensive contact of 360 degree has fully guaranteed can not produce the phenomenon that the connector temperature raises with the contact area of imitating; Because holding screw forms a circular face, for the insulation screen of a circle of follow-up formation is created fine condition.

Embodiment
Among the embodiment, the compound inslation pipe type cable forms by outside clamping piece 1, bonding conductor 3, pipe type cable body 4 and inner clamping piece 5 are nested successively from outside to inside in the junction of centre, and four are hollow tubular structures.Compound inslation pipe type cable body 4 is six circular ports on each equidistant brill of junction, two ends, and outside clamping piece 1 and bonding conductor 3 also all are drilled with the circular port the same with pipe type cable conductive body 4, and inner clamping piece 5 is provided with and the suitable tooth in the hole of other parts.Trip bolt 2 passes circular hole and tightens, with each parts by bolted together.Inside and outside clamp clip adopts semicircle inside and outside clamp clip of non-magnetic rustproof steel to be put together by two, form the thrust of a disc, the bonding conductor that cooperates a disc of formation of two semicircles guarantees that bonding conductor contacts with high the coincideing of pipe cable body.
