Abstract
The invention discloses a crimping-type wire clamp. The wire clamp comprises an outer clamp wire sleeve. The outer clamp wire sleeve possesses a top-down long groove passing through a front portion and a rear portion so that the outer clamp wire sleeve of two sides of the long groove forms two clamp arms arranged oppositely. Inner surfaces of the two clamp arms are correspondingly provided with sinking grooves which are recessed inwardly from the inner surfaces. An inner wire clamp core located in the long groove is arranged in an outer wire clamp sleeve. A side wall surface corresponding to the inner surface of the clamp arm on the inner wire clamp core is a slope surface which is gradually close to the corresponding clamp arm from top to bottom so that the inner wire clamp core and the clamp arm form a cable channel which gradually becomes narrow from top to bottom. The inner wire clamp core and the outer clamp wire sleeve are connected through a bolt passing through the inner wire clamp core, a groove and the outer clamp wire sleeve. The structure is simple and installation is convenient. The clamp possesses advantages that structure intensity is high; loosening and wire clamp sliding are not easy to generate; and cable clamping reliability is high.
Description
Technical field
The present invention relates to a kind of compression joint type wire clamp.
Background technology
Wire clamp be for cable corner, continue and the connection of terminal.Tradition parallel groove clamp adopts ferrous material, and iron is magnetic conductor, easily produces vortex phenomenon, causes energy loss.Existing most of wire clamp adopts aluminium alloy to make, and it has extremely strong strain insulator intensity, without concentrated stress, optical cable is played to the effect of protection and auxiliary vibration damping.
Existing wire clamp adopts button type structure mostly, namely two pieces of corresponding up and down wireplints are set, on two wireplints, correspondence arranges two deep gouges, deep gouge corresponding on two pieces of wireplints forms a cable passage jointly, article two, cable is placed in cable passage respectively, by bolt, two wireplints is compressed the clamping that can realize cable.There is following shortcoming in this wire clamp: first, in cable clamping process, and large and the holding compressing into line cable clip by two wireplints of bolt pressurized, high to the requirement of mechanical strength of tension disc, thus the phenomenon causing bad mechanical strength, easily loosen; Next, this opposite-compacting type cable clamping, its effective pressure-bearing contact area is little, thus easily occurs clamping the phenomenons such as loosening or wire clamp slippage.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of mechanical strength high, not easily loosen and the compression joint type wire clamp of cable good clamping effect.
For solving the problems of the technologies described above, the compression joint type wire clamp provided comprises outer clamp cover, its design feature is: outer clamp tackling has from top to bottom and the through elongated slot in front and back thus make outer clamp cover formation two jig arm be oppositely arranged of elongated slot both sides, on the inner surface of two jig arm, correspondence is provided with the deep gouge be inwardly recessed from its inner surface, the interior lines sandwich being arranged in elongated slot is provided with in described outside line chuck, on the sandwich of interior lines, the surface of the sidewall of corresponding jig arm inner surface is the close slope of the jig arm from top to bottom gradually corresponding to it, thus make between the sidewall of interior lines sandwich and the inner surface of jig arm along with interior lines sandwich narrows gradually to stretching in elongated slot, pass through through interior lines sandwich between described interior lines sandwich and outer clamp overlap, the bolt that groove overlaps with outer clamp is connected.
After adopting said structure, two parallel cables are arranged in elongated slot, and cable sinks in the deep gouge of jig arm, interior lines sandwich is stretched in above-mentioned elongated slot, on the sandwich of interior lines, the sidewall of corresponding jig arm inner surface coordinates with deep gouge and is clamped by cable, along with screwing of bolt, the bottom land of slope and deep gouge extrudes cable gradually, thus complete the firm grip of cable, in the clamping process of whole cable, install very convenient, interior lines sandwich stretch in process, article two, cable bears horizontal extruding force and uniform force, stress is cancelled out each other, enhance total intensity, clamp the stressed reduction of rear bolt, avoid occurring because bolt failure causes the phenomenon easily loosened, and this deep gouge coordinates the mode extruded with inclined-plane, considerably increase the pressure-bearing contact area between cable and wire clamp and extruding force, there will not be wire clamp skidding, substantially increase cable clamping reliability.
As a further improvement on the present invention, the top of described interior lines sandwich is provided with the slotted eye embedded for bolt head, under after described bolt overlaps through outer clamp, the section of stretching is bolted with nut, when interior lines sandwich stretches into, bolt head is located by slotted eye, only need can realize stretching into of interior lines sandwich in spanner screw on nut, install very convenient.
As a further improvement on the present invention, described slope comprises the straight line inclined plane upwards extended from the bottom of interior lines sandwich and the curve slope extending to sandwich top, interior lines from top, straight line inclined plane, the setting of curve slope can make the distance between the top of interior lines sandwich and jig arm reduce further, plays the effect preventing cable from deviating from.
Improve further as of the present invention, the bottom land of described deep gouge is provided with anti-slip veins or anti-skidding salient point again; Described anti-slip veins longitudinal extension and interval arranges many, frictional force when can increase clamping between jig arm and cable, thus effectively avoid the phenomenon that wire clamp slides.
Improve further again as of the present invention, described outer clamp cover to be made and space between two jig arm forms the trapezoidal container cavity broadened gradually from bottom to top by having flexible aluminium alloy after Overheating Treatment, outside line chuck adopts to be had after flexible aluminium alloy makes, in the Thermal Cycling of cable, make whole wire clamp keep certain pressure to cable in clamping process, enhance the chucking power of wire clamp to greatest extent.
Improve further again as of the present invention, the cross sectional shape semicircular in shape of described deep gouge and this semicircular central point is arranged in described deep gouge, the pressure-bearing contact area between cable and jig arm can be increased to greatest extent, thus improve clamping stability.
Improve further as of the present invention, the bottom land of the elongated slot of described outside line chuck is provided with the groove for inserting bottom the sandwich of interior lines, can shorten the height of outside line chuck to greatest extent, thus saves material and production cost again.
In sum, structure of the present invention is simple, it is very convenient to install, have structural strength high, not easily to loosen and wire clamp slides, cable clamping reliability is high advantage.
