Abstract

The utility model discloses a dual-wedge strain clamp which includes a housing, hanging plates hinged on the two sides of the housing, and an inner core arranged in the housing. The inner core is composed of an upper core and a lower core. A wire clamping hole which is used for clamping a lead is arranged between the upper core and the lower core. The upper and lower sides of the inner core are outer wedged faces. Inner walls in the housing which contact with the outer wedged faces of the inner core are inner wedged faces. The dual-wedge strain clamp is big in gripping power, so the phenomenon of loose core can not occur. Besides, the dual-wedge strain clamp is easy to install, thus being suitable for various installation environments.

Description

The double-wedge strain clamp

Technical field

The utility model relates to a kind of double-wedge strain clamp.

Background technology

In order to satisfy power consumption and the Electrical Safety that the city increases day by day, and reduce requirement such as power transmission loss, China's urban distribution network construction development rapidly.In order to satisfy the demand of urban distribution network construction project, relevant corollary equipment demand also increases day by day, and the frequent strain clamp of use is one of them of numerous electrical network accessories in electrical network.There is more shortcoming in existing strain clamp, and the one, little easy the loosing core of grip; The 2nd, the performance after installation technology and workman's installation level affects is installed to product.Existing a kind of hydraulic strain clamp has the big advantage of grip, but the hydraulic strain clamp is installed very trouble, needs the hydraulic construction tool, and particularly for mountain area or ungetable area, construction is just inconvenient more.Therefore existing strain clamp or grip are not enough looses core easily, or trouble is installed, and is difficult for popularizing and uses.

The utility model content

To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of double-wedge strain clamp, and it not only has stronger grip, also has convenient installation.

To achieve these goals, the technical scheme that the utility model adopted is: the double-wedge strain clamp comprises shell; Be articulated in the link plate of shell dual-side, also comprise the inner core that is positioned at shell, said inner core is combined by last core and following core; The said clamp hole that has the clamping lead between core and the following core of going up; It is characterized in that the two sides up and down of said inner core are outer lozenges, the contacted inwall of outer lozenges of said enclosure and said inner core is interior lozenges.

Preferably, said shell is cut with scissors each other to detain by four identical shell sheets of structure and forms.

Preferably, the gradient of said interior lozenges is not less than the gradient of said outer lozenges.

Preferably, the gradient of said interior lozenges equals the gradient of said outer lozenges.

Preferably, said clamp hole is a slotted eye.

Preferably, the said core bottom surface of going up has reference column, and said core end face down has location hole, and said upward core is inserted in through reference column with following core and is connected the location in the location hole.

After adopting said structure; The utility model is compared the advantage that is had with prior art: inner core is unpluged core is shared with following core; Lead is put into the clamp hole will go up core and following core more altogether, then inner core is inserted in the shell together with lead, so just accomplished installation process; It is simple and convenient that therefore ten minutes is installed, and under what condition, can very conveniently accomplish installation process no matter be apace; Wedge-like engagement through shell and inner core; The pulling force that lead is produced acts on the inner core through frictional force, and move inner core to and move with respect to shell, but owing to pass through wedge-like engagement between them; Make inner core mobile more just held by shell tight more; And inner core is held and is made that inner core must be tight more with wire clamp after tighter, and the frictional force between inner core and the lead is just bigger, thereby inner core is just hauled opposite shell by lead further and moves ... So circulation; The situation that causes lead to be grasped by inner core fully the most at last and can not loose core is equivalent to have bigger grip.Therefore the utlity model has the advantage that grip very much not can be loosed core, and easy for installationly be adapted to various installation environments.

Embodiment

The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection range of the utility model.

Embodiment, see illustrated in figures 1 and 2:

The utility model is a kind of double-wedge strain clamp, comprises shell 10, is articulated in the link plate 20 of shell 10 dual-sides; Also comprise the inner core 30 that is positioned at shell 10; Said inner core 30 is combined with following core 33 by last core 32, and the said clamp hole 34 that has clamping lead 40 between core 32 and the following core 33 of going up is characterized in that; The two sides up and down of said inner core 30 are outer lozenges 31, and said shell 10 inner outer lozenges 31 contacted inwalls with said inner core 30 are interior lozenges 11.The utility model when mounted; Inner core 30 unpluged core 32 is shared with following core 33; Lead 40 is put into clamp hole 34 will go up core 32 and following core 33 more altogether, then inner core 30 is inserted in the shell 10 together with lead 40, so just accomplished installation process; It is simple and convenient that therefore ten minutes is installed, and under what condition, can very conveniently accomplish installation process no matter be apace; Through the wedge-like engagement of shell 10 with inner core 30; The pulling force that lead 40 is produced acts on the inner core 30 through frictional force, and move inner core 30 to and move with respect to shell 10, but owing to pass through wedge-like engagement between them; Make inner core 30 mobile more just held by shell 10 tight more; And inner core 30 is held that to make that inner core 30 holds lead 40 after tighter tight more, and the frictional force between inner core 30 and the lead 40 is just bigger, thereby inner core 30 is just hauled opposite shell 10 by lead 40 further and moves ... So circulation; The situation that causes lead 40 to be grasped by inner core 30 fully the most at last and can not loose core is equivalent to have bigger grip.Wherein, said shell 10 preferably cuts with scissors button by four identical shell sheets of structure each other to be formed, and is provided with like this, removes and installs conveniently.

In order further to promote the chucking power of 10 pairs of inner cores 30 of shell; The gradient of lozenges 11 is not less than the gradient of said outer lozenges 31 in said; Like this can be so that inner core 30 is clamped by shell 10 in the process that trend moves further; Thereby can further lead 40 tightly be grasped, preferably, the gradient of said interior lozenges 11 equals the gradient of said outer lozenges 31.Said clamp hole 34 is a slotted eye, can make the frictional force between the two have obvious lifting so that inner core 30 has bigger contact-making surface with lead 40.For the last core 32 that makes inner core 30 receives lead 40 frictional force relatively more balanced with following core 33; Said core 32 bottom surfaces of going up have reference column 35; Said core 33 end faces down have location hole 36, and said upward core 32 is inserted in the location hole 36 through reference column 35 with following core 33 and is connected the location, and core 32 and following core 33 are fused; Can not relatively move, make the clamping of 30 pairs of leads 40 of inner core more stable.

The utlity model has the advantage that grip very much not can be loosed core, and easy for installationly be adapted to various installation environments.
