Abstract
The invention discloses a strain clamp for insulated power cables clustered in parallel. The strain clamp comprises a body with a wedge-shaped cavity, wherein two wedge cores matched for use in pairs are arranged in the wedge-shaped cavity; a tension rod is connected to the body which is formed by movably butting two semi-shells with wedge-shaped cavities inside; and the butt joints of the two semi-shells are both provided with dovetail groove structures which are connected with each other. When in use, first, the insulated power cables clustered in parallel are clamped only by matching a pair of wedge cores; then, two semi-shells are connected to form the body through the dovetail groove structures; and finally, the installation can be completed by putting the wedge cores into the wedge-shaped cavities of the body without twisting the insulated power cables clustered in parallel; the strain clamp is easy and convenient to operate; and the installation difficulty is low. Moreover, lead wires are clamped by utilizing the wedge cores directly, the clamping force is strong, the sliding of the lead wires is avoided, and line operation reliability is improved.
Description
Technical field: the present invention relates to a kind of electric armour clamp, particularly the strain clamp of fixing parallel beaming type insulated cable.
Background technology: the parallel beaming type insulated cable of the increasing use of the insulated cable that in electric line, uses; When using general strain clamp to be fixed on bunched cable on the electric pole; Need each bar wire core be separated operation respectively again fixes; Such complicated operation, specification requirement is high, and damages lead easily.Chinese patent 03210522.3 discloses a kind of four-core centralized cable strain clamp, utilizes cross core bar to be contained in the middle of the four-core centralized cable, and clamps tensioning in the wedge cavities that penetrates wire clip body again with the voussoir of two cooperations.Need not during use Bundling conducting wire is separated one by one, and wedge-like engagement can make lead open tighter and tighter also not fragile cable.But; This strain clamp needs parallel conductor cable being twisted into square when mounted, and bunched cable is more bothersome to turning round, and especially the parallel beaming type insulated cable for larger cross-section installs difficulty more; Often need many people to accomplish, convenient inadequately.
Summary of the invention: to the deficiency of prior art, it is a kind of easy for installation that the present invention provides, the reliable parallel beaming type insulated cable strain clamp of clamping.
The present invention includes the body that is provided with wedge cavities; Two wedge cores that are used in pairs then place wedge cavities; Pull bar is connected on the body, and body is that the movable butt joint of half housing of wedge cavities is formed by two inside, and the joint of this two and half housing is equipped with oat tail groove structure and connects mutually.
When using, the present invention only needs parallel beaming type insulated cable is clamped in a pair of wedge core cooperation; Again two and half housings are connected to form body through oat tail groove structure; The wedge cavities of at last the wedge core being put into body can be accomplished installation; Need not parallel beaming type insulated cable turning round, operate easy and conveniently, installation difficulty is low.And the present invention utilizes the direct clamping lead of wedge core, and chucking power is strong, avoids the lead slippage, improves the circuit reliability of operation.
Further specify the present invention below in conjunction with accompanying drawing and embodiment.

Embodiment: to shown in Figure 4, body is provided with 2 in the wedge core that 3, two of wedge cavities are used in pairs and places wedge cavities 3 like Fig. 1, and pull bar 10 is connected on the body.Body is that the movable butt joint of half housing 1 of wedge cavities 3 is formed by two inside, and the joint of this two and half housing 1 is equipped with oat tail groove structure 4 and connects mutually.
Extremely shown in Figure 8 like Fig. 5; The correspondence that on sandwich serface, is provided with a wedge core 2 of present embodiment pierces through the thorn point 5 of parallel boundling insulated cable 11 middle band muscle; And be provided with protruding square column 6, and then being provided with square hole 7 and square column 6 corresponding matching on another wedge core 2, such two wedge cores 2 cooperate the location more firm.Be equipped with arc depression 8 on the sandwich serface of two wedge cores 2; Each core of parallel boundling insulated cable 11 can place corresponding arc depression 8 clampings to fix; Also be provided with friction enhanced muscle 9 on the sandwich serface, can strengthen with the frictional force of parallel beaming type insulated cable 11, clamping is more reliable.
When installing and using; Two wedge cores 2 cooperate clamps parallel beaming type insulated cable 11; Thorn point 5 is with muscle in the middle of piercing through parallel boundling insulated cable 11, square hole 7 and square column 6 corresponding matching, and each core of parallel boundling insulated cable 11 can place corresponding arc depression 8 clampings to fix.Then two and half housings 1 are movably connected to form body through oat tail groove structure 4; The wedge core 2 that to clamp parallel beaming type insulated cable 11 is at last put into the wedge cavities 3 of body and is promptly accomplished installation; Quick and easy for installation; Chucking power to cable can be increasing trend under deadweight and tensile force effect, clamping is very reliable.10 on pull bar is to be used for being connected with other gold utensil whole wire clamp is fixed on electric pole.
