Example (b):

referring to fig. 1-5, the present invention provides a technical solution: an easy-to-detach heat-shrinkable tube for an electrical connector comprises an insulating outer layer 1 and a hot-melt inner layer 2, wherein the insulating outer layer 1 is coated outside the hot-melt inner layer 2;

the clamping ring components 3 are sleeved at two ends of the outer wall of the insulating outer layer 1, each clamping ring component 3 comprises an open-ended circular ring 31, supporting plates 32 are connected to two sides of an opening of each circular ring 31, a movable groove is formed in one side of the opening of each circular ring 31, the other side of the opening of each circular ring 31 is embedded into the movable groove, supporting springs 33 are supported between the supporting plates 32 on two sides, one end of the opening of each circular ring 31 is inserted into the other end of the opening of each circular ring 31, the movable groove is formed in each circular ring 31, the opening of each circular ring 31 can enable the two ends to move relatively and adjust through the movable groove (shown in figure 5), the supporting springs 33 are arranged, the supporting plates 32 on two sides are pushed towards the direction away from each other, so that the circular rings 31 can be tightened, and can be tightly;

the outer wall of the insulating outer layer 1 is provided with a through groove 4, the outer wall of the hot-melt inner layer 2 is connected with a hand-tearing opening plate 5, the hand-tearing opening plate 5 penetrates through the through groove 4 and extends to the upper side of the insulating outer layer 1, the hand-tearing opening plate 5 is connected with the insulating outer layer 1, when the heat shrink tube needs to be taken down for maintenance, the insulating outer layer 1 is torn through the hand-tearing opening plate 5, so that the heat shrink tube can be quickly torn down from the inside, and the hand-tearing opening plate 5 can be conveniently pinched by the arrangement of the through groove 4;

evenly be provided with friction sand grip 6 on insulating outer 1's the inner wall, friction sand grip 6 is cyclic annular setting on insulating outer 1's the inner wall, through the setting of friction sand grip 6 for friction sand grip 6 increases with the electric connector part frictional force of inside, thereby makes the pyrocondensation pipe be difficult to follow the condition of electric connector department slippage, thereby increases the effort of being connected of pyrocondensation pipe and electric connector.

The diameter of the insulating outer layer 1 is in a shape with small ends and large middle, so that the installation effect on the electrical connector is facilitated, and the diameter of the outer part can be quickly reduced after the outer part is heated.

There is blotter 34 through the bonding of adhesive on the inner wall of ring 31, and blotter 34 is the rubber blotter, through the setting of blotter 34 for be kept apart between ring 31 and the insulating outer layer 1, thereby avoid direct contact's the wearing and tearing condition.

Be provided with indent formula crease 7 on the outer wall of hot melt inlayer 2, and indent formula crease 7 is located and passes through on the position that groove 4 corresponds, through the setting of indent formula crease 7 for indent formula crease 7 department hot melt inlayer 2's thickness is less than the thickness of other positions, and indent formula crease 7 is located near hand tear opening plate 5, thereby makes things convenient for hand tear opening plate 5 will hot melt inlayer 2 and tear more.

The ring 31 is a stainless steel ring or a copper ring, so that the toughness is good, and the resetting can be fast.

Insulating outer 1 is the insulating outer of crosslinked polyolefin, and hot melt inlayer 2 is the compound inlayer of hot melt adhesive, and integrated into one piece between hot melt inlayer 2 and the friction sand grip 6.

The working principle is as follows: pinching the support plates 32 at two sides of the clamping ring assembly 3 towards the middle, so that the support spring 33 is compressed and the diameter of the circular ring 31 is increased, at the moment, the two clamping ring assemblies 3 are respectively sleeved at two ends of the insulating outer layer 1, then the heat shrink tube is sleeved at the position where the electric wires need to be wired, the heat shrink tube is moved towards one side, the electric connectors needing to be connected are connected, then the heat shrink tube is movably sleeved at the connecting position, the heat shrink tube is wrapped at the electric connectors in a mode that the outer wall is heated, and the circular ring 31 is tightly held on the outer wall of the insulating outer layer 1 under the elastic force action of the support spring 33;

when the joint department goes wrong, knead the backup pad 32 of both sides together to make clamp ring subassembly 3 break away from insulating outer 1, handheld hand tears open board 5 and tears hot melt inlayer 2 from inside and drive outside insulating outer 1 from passing through groove 4 and tearing, can be quick take off the pyrocondensation pipe from electrical connector, and the pyrocondensation pipe is disposable usually, and other modes are also to the pyrocondensation pipe destruction, consequently, do not cause too extravagant.

Having shown and described the basic principles and principal features of the invention and advantages thereof, it will be apparent to those skilled in the art that the invention is not limited to the details of the foregoing exemplary embodiments, but is capable of other specific forms without departing from the spirit or essential characteristics thereof; the present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
