Abstract
The utility model discloses a strain clamp of an aluminium alloy cored aluminum stranded wire. The strain clamp includes a steel anchor and a drainage wire clamp which is connected with the steel anchor. An end of the steel anchor is connected with an anchor head. The outside of the anchor head is covered with an inner crimping pipe and an outer sleeve from inside to outside. The inner crimping pipe is provided with a cavity which is used to embed an inner core of a to-be-connected aluminium alloy cored aluminum stranded wire. Through arranging the inner crimping pipe and the outer sleeve covering the inner crimping pipe, when the aluminium alloy cored aluminum stranded wire is pressed by the clamp, the pressing force presses a lead after passing through two pipe walls, so the pressing force is distributed to the force-carrying steel anchor, and consequently the force uniformity of the aluminum stranded wire is guaranteed, and the gripping power of the strain clamp to the aluminum stranded wire is improved. The strain clamp is simple and reasonable in structure, convenient and reliable in anchor connection, and reasonable in force distribution, and can be widely applied to the power transmission line construction of the aluminium alloy cored aluminum stranded wire.

A kind of strain clamp of aluminium alloy core aluminium stranded conductor; Comprise steel anchor and the drainage wire clamp that connects with the steel anchor; The end of said steel anchor is connected with anchor head; The outside from-inner-to-outer of said anchor head is with internal layer aluminium hydraulic pressed connecting pipe and outer layer sleeve successively, is provided with the cavity of the inner core embedding of holding aluminium alloy core aluminium stranded conductor to be connected in the said internal layer aluminium hydraulic pressed connecting pipe.
As the further improvement of technique scheme, said internal layer aluminium hydraulic pressed connecting pipe is an aluminium alloy element, and outer layer sleeve is aluminium matter or aluminium alloy matter member
As the further improvement of technique scheme, an end of said outer layer sleeve and the terminal socket of steel anchor are in the internal layer aluminium hydraulic pressed connecting pipe is coated on fully.
Further improvement as technique scheme is provided with bushing pipe in the said outer layer sleeve.
As the further improvement of technique scheme, the end of said steel anchor is provided with some roads depression.
As the further improvement of technique scheme, said anchor head is provided with some roads depression.
As the further improvement of technique scheme, the end diameter of said steel anchor is greater than the diameter of anchor head.
The beneficial effect of the utility model is: the utility model is through having added internal layer aluminium hydraulic pressed connecting pipe and the outer layer sleeve that entangles it; Make when the aluminium alloy core aluminium stranded conductor carries out the wire clamp pressing; The power of pressing needs through two-layer tube wall lead to be exerted pressure; So just, pressure force is distributed on the stressed steel anchor, has guaranteed the uniformity that aluminium stranded conductor is stressed, improved the grip of strain clamp aluminium stranded conductor.The utility model is simple and reasonable, be anchored convenient and reliable, reasonable stress, the transmission line that is widely used in the aluminium alloy core aluminium stranded conductor sets up.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the internal structure cutaway view of the utility model when being used to connect the aluminium alloy core aluminium stranded conductor.
Embodiment
With reference to Fig. 1; A kind of strain clamp of aluminium alloy core aluminium stranded conductor; Comprise steel anchor 1 and the drainage wire clamp 5 that connects with steel anchor 1; The end of said steel anchor 1 is connected with anchor head 11, and the outside from-inner-to-outer of said anchor head 11 is with internal layer aluminium hydraulic pressed connecting pipe 12 and outer layer sleeve 13 successively, is provided with the cavity of the inner core embedding of holding aluminium alloy core aluminium stranded conductor to be connected in the said internal layer aluminium hydraulic pressed connecting pipe 12.Particularly, steel anchor 1 is an one with anchor head 11, and said steel anchor 1 links through drainage plate 4 and drainage wire clamp 5, and described drainage plate 4 is welded as a whole with body 13.During work, the inner core 6 of aluminium alloy core aluminium stranded conductor to be connected is positioned at internal layer aluminium hydraulic pressed connecting pipe 12, and front end and anchor head 11 lean.The mechanical performance of lead is communicated on the anchor head 1 through internal layer aluminium hydraulic pressed connecting pipe 12 and outer layer sleeve 13, and is communicated to the terminal, and the electric property of lead, is communicated on the drainage wire clamp 5 through drainage plate 4 by outer layer sleeve 13.In addition, drainage wire clamp 5 can divide 0 ° and 30 ° of drainage settings.Steel anchor 1 is provided with the steel anchor ring at the end away from anchor head 11, and the steel anchor ring is used for being connected with the insulator string of peripheral hardware.
Further as preferred embodiment, said internal layer aluminium hydraulic pressed connecting pipe 12 is aluminium matter member with outer layer sleeve 13.In order to make follow-up mechanical pressing smooth, internal layer aluminium hydraulic pressed connecting pipe 12 adopts aluminum pipe as raw material with outer layer sleeve 13, and itself has promptly had plastic deformation like this, after deforming through mechanical pressing, just can inner core 6 and anchor head 11 be anchored together securely.Certainly, also can adopt other similar plastic materials to be used as the material of two sleeve pipes, it also belongs to the variant that is equal to of the utility model.
