Description

Buffer-type cable anchor ear

Technical field

The utility model relates to a kind of anchor ear, particularly a kind of buffer-type cable anchor ear.

Background technology

In electric power system, the cable media that is absolutely necessary.Generally be by on cable bearer, using the plastics bandage to fix cable, also having anchor ear to fix by rigidity.Shortcoming is that plastics are easily aging just to make that maintenance cost improves greatly; Bandage or rigidity anchor ear and cable, support do not have buffering for being fastenedly connected, and cause can't cushioning during cable flexing when the power supply folding or under the wind-force effect, and anchor ear, support etc. just has the possibility of fracture, and security performance is relatively poor.

The utility model content

The technical problems to be solved in the utility model is, overcomes above technological deficiency, provides a kind of security performance height, the buffer-type cable anchor ear that maintenance cost is lower.

Technical solution of the present utility model is, a kind of buffer-type cable anchor ear with following structure is provided, comprise the anchor ear body, be fixed with a buffer unit that plays cushioning effect can make cable flexing the time in described anchor ear inner body wall bottom, described buffer unit is made of first deformation mechanism and second deformation mechanism.

After adopting above structure, the utility model top cover compared with prior art has the following advantages:

Because the utility model buffer-type cable anchor ear is being fixed with a buffer unit that plays cushioning effect can make cable flexing the time in described anchor ear inner body wall bottom, described buffer unit is made of first deformation mechanism and second deformation mechanism, by designing double-deck flexible deformation mechanism, when placed cable in anchor ear after, first deformation mechanism can bear certain pressure and the safeguard protection effect is played in the flexural deformation shock-absorbing; Greatly promptly bear pressure when big when the specification of cable becomes, can also pass through first deformation mechanism, second deformation mechanism flexural deformation simultaneously shock-absorbing, guarantee that cable can mount safely, reach anchor ear, support does not have damage, increase the service life.

As a kind of improvement of the present utility model; the shape plate of selling off that described first deformation mechanism comprises the direct following spill plate that contacts with cable surface, fixedlys connected with following spill plate and be positioned at its both sides constitutes more; described spill plate down is an one with selling off the shape plate more; when cable is swung because of outside cause; following spill plate bears pressure to be changed; and the flexural deformation plate of both sides to some extent deformation with the variation of the power that cushions this swing and cause; do not relate to anchor ear shell and cable bearer, play a protective role.

As another improvement of the present utility model, described second deformation mechanism is that the bent plate of semicircular ring shape constitutes by cross section, described bent plate is positioned at the first deformation mechanism inner chamber, the top of described bent plate is gapped with the bottom of following spill plate, when bearing the cable of big specification, can make that under the effect of pressure the spill plate directly contacts with bent plate down, passes to bent plate to partial pressure, bent plate can be out of shape the buffering shock-absorbing, has improved the security performance of anchor ear, support more.

As another improvement of the present utility model, the top of described bent plate is 3 millimeters with the bottom gap of following spill plate, and when distance was too big, first deformation mechanism moderate finite deformation may take place can not recover, and second deformation mechanism does not play a role; Distance too hour does not reach the effect of buffering shock-absorbing.

As another improvement of the present utility model; also be provided with a buckle reaches and several draw-in grooves that are clasped at anchor ear body openings place; when being placed on the cable of different size in the anchor ear, select buckle to cooperate chucking with suitable draw-in groove, play the safeguard protection effect.

As another improvement of the present utility model; the upper end of described buckle also is provided with kick; described draw-in groove upper end is provided with the little groove that cooperates with kick; when cooperating, allow one of them kick and little groove fit; the another one kick is played and is increased the anti-skidding effect of friction, and duplicate protection can be safer.

As of the present utility model another improve, the bottom of described anchor ear body is provided with and is used to through hole that fastening bolt is passed through, by through hole anchor ear is fixed on above the cable bearer, this connected mode is safety more firmly.
