Detailed Description

For a better understanding of the contents, features and effects of the present invention, the following embodiments will be illustrated in detail with reference to the accompanying drawings. It should be noted that the present embodiment is illustrative, not restrictive, and the scope of the invention should not be limited thereby.

An insulating clamp for installing an insulating sheath of an isolating switch comprises a clamp body 4 and a sleeve 6, wherein one clamp head of the clamp body is a jacking clamp head 1, and the other clamp head of the clamp body is a bearing clamp head 3; a jacking blind hole 2 is formed in the clamping side surface of the jacking tong head; the bearing binding clip is of a C-shaped structure, and is axially limited and hung on the circumferential outer wall of the sleeve; the sleeve is of a C-shaped structure buckled in the bearing binding clip, one end of the sleeve is limited and supported on the axial end face of the bearing binding clip, and the sleeve at the end is axially limited and bears the insulating sheath 9; the insulating sheath penetrates through the sleeve in the axial direction and is inserted in the sleeve.

Preferably, the circumferential outer wall of one end of the sleeve is integrally provided with a radially extending arc-shaped outer edge 7, and the axial inner wall of the sleeve at the end is integrally provided with a damping ring 8 which is sleeved and matched on the axial outer wall of the insulating sheath; the arc outer edge is axially supported and limited by the side surface of the binding clip; the axial end face of the damping ring axially supports the limiting insulating sheath.

Additionally, the utility model discloses preferentially, the sleeve can adopt elastic rubber to make, and telescopic circumference outer wall and the circumference inner wall clearance fit of bearing binding clip are by the inner wall restraint sleeve of bearing binding clip to, the epaxial radial interval in insulating sheath of further compression of damping ring on the sleeve circumference inner wall and the bearing binding clip extrudees telescopic deformation space, avoids the sleeve to take place too big deformation and leads to insulating sheath to break away from the sleeve.

For a more clear description of the embodiments of the present invention, the following provides an example:

the utility model discloses an installation isolator insulating sheath's insulating clamp can set up reset spring 5 in the handle department of the pincers body as required in the use, and reset spring's both ends shore respectively on the side in opposite directions of two handles of the pincers body.
