Abstract
A four-core-centralized strain clamp comprises a main body provided with wedge-shaped cavities. A pull rod is connected with the main body; wedge cores which are matched in pairs when in use are placed in the wedge-shaped cavities of the main body; the quantity of the wedge-shaped cavities of the main body is two; a through groove is formed on the outer side wall of each wedge-shaped cavity to form a main body structure with two back-to-back C-shaped sections; and the quantity of the corresponding wedge cores are two pairs; and the left haft parts and the right half parts of four-core centralized leads are respectively placed in the corresponding wedge cores to be clamped and fixed. When the four-core centralized leads are mounted, the wider middle parts are only required to be cut; and two electric wire cores are mounted in each wedge-shaped cavity; and the parallel centralized leads are not required to be twisted into a square, so that the operation is easy and convenient, and the installation difficulty is low. Moreover, the utility model utilizes the two pairs of wedge cores to directly clamp the leads to ensure stronger clamping force, thereby avoiding the slippage of the leads and improving the running reliability of routes. The wedge cores can rotate along with the leads, so that the automatic regulating power is balanced. The wedge cores also can be replaced; and the clamp can be disassembled and reused, so that the operation and the maintenance are easy, and the low is low.
Description
Technical field: the utility model relates to a kind of electric armour clamp, particularly fixes the strain clamp of four-core centralized lead.
Background technology: the four-core centralized lead that power transmission and distribution are used is that four wire cores fuse, when using general strain clamp to be fixed on Bundling conducting wire on the electric pole, each bar wire core need be separated again operation respectively and fix such complicated operation, the specification requirement height, and damage 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 lead.But this strain clamp when mounted need be with parallel four-core centralized lead to being twisted into square, and be installed in the same wedge cavities of wire clamp, and four-core centralized lead is more bothersome to turning round, and often needs many people just can finish, and is convenient inadequately.And the cross core bar of voussoir and liner cooperates the chucking power of clamping wire not high enough, may produce slippage between each wire core, influences the circuit operation.
Summary of the invention: at the deficiencies in the prior art, it is a kind of easy for installation that the utility model provides, the reliable four-core centralized strain clamp of clamping.
The utility model comprises the body that is provided with wedge cavities, the inwall of wedge cavities is an arc surface, pull bar is connected on the body, the wedge core that is used in pairs then places the wedge cavities of body, and the wedge core outer surface also is arc surface, and the wedge cavities of body has two, each wedge cavities lateral wall is provided with groove, forming the cross section is two body constructions that lean against " C " font, and corresponding wedge core also is two pairs, and the left and right halves of four-core centralized lead places corresponding wedge core clamping to fix respectively.
Wire clip body of the present utility model is provided with two wedge cavities, only needs when four-core centralized lead is installed the wide middle place is cut, and each wedge cavities is installed two wire core, need not parallel Bundling conducting wire squarely to being twisted into, and operates easy and conveniently, and installation difficulty is low.And the utility model utilizes two pairs of direct clamping leads of wedge core, and chucking power is stronger, avoids the lead slippage, improves the circuit reliability of operation, and the wedge core can rotate with lead in wedge cavities, automatically moderating force's balance.The wedge core can also be changed according to the specification of lead, and wire clamp then can be dismantled repeated use, and Operation and Maintenance is easy, reduces cost.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the front view of embodiment;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A-A profile of Fig. 1;
Fig. 4 is the schematic diagram of body among Fig. 3;
Fig. 5 is the schematic diagram of wedge core among Fig. 3.
Embodiment: as shown in the figure, body 1 is provided with wedge cavities 2, and the inwall of wedge cavities 2 is an arc surface, and pull bar 4 is connected on the body 1, and 3 in the wedge core that is used in pairs places the wedge cavities 2 of body 1, and wedge core 3 outer surfaces also are arc surface.The wedge cavities 2 of body 1 has two, each wedge cavities 2 lateral wall is provided with groove 5, forming the cross section is two body constructions that lean against " C " font, and corresponding wedge core 3 also is two pairs, and the left and right halves of four-core centralized lead 8 places corresponding wedge core 3 clampings to fix respectively.In fact, can be equipped with arc depression 6 on the sandwich serface of every pair of wedge core 3, four-core centralized lead 8 places corresponding arc depression 6 clampings to fix, and the clamping location of lead is convenient reliable.
When installing and using, dowel in the middle of the parallel four-core centralized lead 8 is cut open, two wire cores are lived at arc depression 6 places of every pair of wedge core 3 clamping respectively, then two pairs of wedge cores 3 are put into two wedge cavities 2 of body 1 respectively, the remainder of four-core centralized lead 8 then can be put into by the groove 5 of body 1 sidewall.Strain four-core centralized lead 8 then because wedge core 3 and body 1 be for arc surface contacts, to the chucking power of lead 8 conduct oneself with dignity and the tensile force effect under can be increasing trend, clamping is very reliable.And even lead 8 is rotated, the wedge core 3 of clamping also can rotate in wedge cavities 2, automatically moderating force's balance.Generally also scribble lubricating oil, rotate more smooth and easy at the contact-making surface place of wedge core 3 and wedge cavities 2.4 on pull bar is to be used for being connected with other gold utensil whole wire clamp is fixed on electric pole.
