Abstract

The utility model relates to a wedged insulating tension clamp, which comprises a base with notches, and a plastic clamp core mechanism is respectively mounted between the notches and on the front side and the rear side of the base. The connection of the plastic clamp core mechanisms with the notches forms a wedged structure, two ends of a steel wire rope are connected with the upper side and the lower side of the base, the front end of the steel wire rope is connected with a U-shaped plastic ring, the connections of the steel wire rope with the upper side and the lower side of the base are limited through a fixing mechanism, a reversed wedged structure opposite to the wedged structure is further mounted between the plastic clamp core mechanisms and the notches, and connections of the left sides and the right sides of both the front end and the rear end of the reversed wedged structure with the base are respectively provided with a plastic block. The wedged insulating tension clamp has the advantages that installation can be completed without tools, and the clamp is simple in construction, convenient in operation and high in construction efficiency, avoids galvanic corrosion caused by contact of different metals, enhances corrosion resistance, and prolongs service life.

Description

Wedge type insulation strain clamp

Technical field

The utility model relates to and a kind of cable or the stretch-draw of bunched cable two ends is fixed to the strain clamp of bar or tower, relates in particular to the structure of this strain clamp (JBGA).

Background technology

In the built on stilts electric power system of 0.6/1KV, cable or the stretch-draw of bunched cable two ends need be fixed on bar or the tower, use strain clamp.

There is following shortcoming in screw bolt-type strain clamp (as shown in Figure 1) commonly used:

The first, installation complexity, it is not convenient to operate, efficient is low: screw bolt-type strain clamp commonly used is when installation, after insulating barrier must be removed earlier wire clamp is installed, when wire clamp is installed, need come fastening with instrument, as in work high above the ground especially inconvenience, after fastening finishing, also need to install supporting insulating coating to reach insulation property.

The second, product cost height, how complicated production process is.

Three, insulation property are poor: insulation again after original insulation breakdown is fallen, and in lap-joint, and the sealing part poor insulativity, rainwater can enter in the insulating barrier, and the corroding metal conductor influences electrical property and useful life.

Summary of the invention

The utility model technical issues that need to address have provided a kind of wedge type insulation strain clamp, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: a pedestal that has notch; Between notch, the forward and backward both sides of pedestal settle a plastic clip core mechanism; Described plastic clip core mechanism and notch connecting place are taper structures; The two ends of steel wire rope link to each other with the upper and lower both sides of pedestal; The front end of steel wire rope and a U plastic ring join; The connecting place of the upper and lower both sides of steel wire rope and pedestal is spacing by a fixed mechanism; Between plastic clip core mechanism and notch, also settle a reverse wedge structure opposite with described taper structure; Described reverse wedge structure is also settled a plastics block respectively in the left and right sides of front end and the left and right sides and the pedestal joint of rear end.

Compared with prior art, the beneficial effects of the utility model are: 1, taper structure uses the section bar manufacturing to form by the aluminium alloy body, is combined into taper structure with plastic clip, in cable is installed in sandwich, can pin cable certainly, lock tightly more, guarantee intensity when load is big more; Owing to be self-locking structure, need not get final product installation by instrument when mounted in addition, construction is simple, simple operation, efficiency of construction height; 2, the plastics sandwich is designed to the arc groove of groove, the cable insulation of can holding with a firm grip, and unlikely again damage cable insulation has more strengthened insulation property; 3, connect carrying with stainless steel wire rope, be placed on the steel wire rope, avoided the different metal contact to produce couple corrosion, strengthen antiseptic property, increase the service life with plastic hoop.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

By Fig. 2, Fig. 3 as seen: the utility model comprises: a pedestal 2 that has notch 21; Between notch 21, the forward and backward both sides of pedestal 2 settle a plastic clip core mechanism 1; Described plastic clip core mechanism and notch 21 connecting places are taper structures; The two ends of steel wire rope 5 link to each other with the upper and lower both sides of pedestal 2; The front end of steel wire rope 5 and a U plastic ring 6 join; Steel wire rope 5 is spacing by a fixed mechanism 3 with the connecting place of the upper and lower both sides of pedestal 2; Between plastic clip core mechanism 1 and notch 21, also settle a reverse wedge structure 40 opposite with described taper structure; Described reverse wedge structure 40 is also settled a plastics block 4 respectively in the left and right sides of front end and the left and right sides and pedestal 2 joints of rear end.

Described fixed mechanism 3 is aluminium riveting balls.

When needs will be fit to the cable connection of scope, at first cable is prepared by the construction specification requirement; During installation, the steel wire end of the present utility model that chooses is fixed to the installation site, the cable that will install penetrates in the plastic core mechanism in the utility model then, and the tension cable gets final product.

Claims

1. a wedge type insulation strain clamp is characterized in that comprising: a pedestal that has notch; Between notch, the forward and backward both sides of pedestal settle a plastic clip core mechanism; Described plastic clip core mechanism and notch connecting place are taper structures; The two ends of steel wire rope link to each other with the upper and lower both sides of pedestal; The front end of steel wire rope and a U plastic ring join; The connecting place of the upper and lower both sides of steel wire rope and pedestal is spacing by a fixed mechanism; Between plastic clip core mechanism and notch, also settle a reverse wedge structure opposite with described taper structure; Described reverse wedge structure is also settled a plastics block respectively in the left and right sides of front end and the left and right sides and the pedestal joint of rear end.
