Description

Wedge strain resistance cable clamp

Technical field

The utility model is related to electric armour clamp technical field, more particularly to a kind of wedge strain resistance cable clamp.

Background technology

Strain clamp is a kind of common gold utensil in power transmission and transformation field, be used to for cable to be connected to strain insulator-string group or bar On tower, and then realize fixed cable and bear cable strain, the structure of conventional wedge strain clamp is complex, cable is installed Operation inconvenience, cable in installation process in wire clamp slide, it is existing have in some On-line Product clamp grooves be designed with anti-Slipped Clove Hitch Structure, although the structure design can improve the present situation of cable slip, because anti-skid structure frictional resistance can make during wiring cable Cable is installed to be become not enough to facilitate；Also be exactly the wedge block that designs in wire clamp of existing product in wire clip body using activity Connection, wedge block can do pulling motion along wire clamp wedge block groove, can be with the antipode when pull is to extreme position Limit tie point does arc swing, and the swing is not easy to the carrying out of the stringing action of cable very much.

Utility model content

For defect present in prior art, the utility model devises a kind of wedge strain resistance cable clamp, and the product passes through Prior art Related product is improved, can be very good to overcome the defect pointed out in prior art.

To achieve these goals, the technical scheme that the utility model is provided is as follows：

Wedge strain resistance cable clamp, including wire clip body and wedge block, are designed with wedge block groove on wire clip body, wedge shape is slided Block one end slide design is designed with gland in wedge block groove on the wedge block other end, wedge block is corresponding with gland It is designed with wire casing；Wedge block groove tip designs have extension block, extension block and wedge block groove link position design limited location knot Structure；Slide rail is designed with wedge block, slip-off preventing pin is designed with wire clip body, slip-off preventing pin coordinates with wedge block slide rail, When wedge block slides into extreme position, position limiting structure offsets with wedge block, and wedge block wire casing is in horizontality；Pressure Lid is designed with location structure with wedge block in wire casing side, and wedge block is connected in oriented side with gland by fastener, the side It is also devised with bolt fastening structure；Unidirectional anti-slip tank is designed with wire casing.

Also design, with Pin hole bolt, is used cooperatively, for wire clamp with Pin hole bolt with nut and closed pin on wire clip body The installation of body.

The location structure is engaged with convex surface by concave surface and is constituted, and correspondence occlusal surface is arc surface.

The bolt fastening structure is constituted by bolt hole and bolt connection on wedge block, gland is designed, on gland The bolt hole of design is being more than bolt with wire casing vertical direction size, and the bolt hole of this kind of size design can increase gland and wedge Shape slide block wire casing size range, such as：Bolt hole on gland can be rectangular opening, or mounting hole；The bolted-on attachment Structure is combined with above-mentioned location structure, and various sizes of cable can be facilitated to be fixedly clamped.

It is triangular hill structure that the unidirectional anti-slip tank is cross section.

Preferably, the unidirectional anti-slip tank is ramp projections structure, and inclined-plane low side is designed for arc chord angle.

Preferably, it is designed with auxiliary mounting hole on wire clip body.

Preferably, reinforcement is also devised with wire clip body, reinforcing rib structure design can ensure wire clip body to line Saving material in the case of the limit tension of cable.

The beneficial effects of the utility model are that, by adopting said structure design, unidirectional anti-skidding slot structure can make cable edge Wire casing unidirectional motion inversely has frictional resistance than relatively labor-saving, realizes unidirectional skidproof effect, and the stringing that can give cable works Bring great convenience, while extension block is designed with position limiting structure with wedge block groove link position is sliding into extreme position When, make wedge block wire casing in horizontality, facilitate stringing to operate, therefore the Technical Design of utility model offer Product can be very good the deficiency for making up prior art products.
