Description

Technical Field

[0001] The utility model relates to the technical field of cable repair, in particular to a clip-on heat shrink cable repair sheet. Background Art

[0002] Cables are important tools for power transmission, and the integrity of their outer sheath is crucial to their working performance. Cables are prone to damage due to some external forces or during transportation. In order to prevent accidents such as cable leakage and electric shock caused by untimely repair of damaged outer sheaths, it is usually necessary to use special materials for repairing damaged cable outer sheaths (such as heat shrink tubing, self-adhesive silicone tube, cold shrink tubing, etc.) to modify the damaged cables;

[0003] When using the existing snap-on heat shrink cable patch, i.e., the zipper-type heat shrink tubing, to repair damaged cables, the overlapping clips and the card strips are generally used to limit the sleeve from falling downwards. However, when installing the overlapping clips to limit the sleeve, the operator usually needs to pinch and tighten a group of card strips at the same time, and needs to adjust the position of the sleeve multiple times. This will cause the sleeve to be time-consuming, labor-intensive, cumbersome and inconvenient during the actual installation of the sleeve. Therefore, a snap-on heat shrink cable patch is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a snap-on heat shrink cable patch to solve the problem that the existing snap-on heat shrink cable patch, i.e., the zipper type heat shrink sleeve, is time-consuming, laborious, cumbersome and inconvenient to install when in use.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A snap-on heat shrink cable patch comprises a heat shrinkable sleeve body, one side end of the heat shrinkable sleeve body is provided with a left clamping strip through integral molding, and the other side end of the heat shrinkable sleeve body is provided with a right clamping strip through integral molding, a slot is provided at one side position inside the left clamping strip, a short rod is provided at one side position of the right clamping strip close to the left clamping strip through integral molding, an auxiliary air bag is bonded to the upper inner side of the heat shrinkable sleeve body, an air inlet plug is provided at the lower position of the auxiliary air bag, and a double-sided tape is bonded to one side position of the auxiliary air bag.

[0007] Preferably, a cable body is provided at the middle position of the inner side of the heat shrinkable sleeve body, and the upper outer part of the cable body is covered with a hot melt adhesive layer, and the hot melt adhesive layer and the heat shrinkable sleeve body are bonded and connected.

[0008] Preferably, the left clamping strip and the right clamping strip are respectively provided with columnar structures, and the left clamping strip and the right clamping strip are externally clamped with overlapping buckle bodies, and the overlapping buckle bodies are provided with “C”-shaped structures.

[0009] Preferably, the top end surface of the overlapping buckle body is provided with notches through integral molding, and the notches are distributed in an equidistant structure along the horizontal direction.

[0010] Preferably, the inner end of the slot and the outer end of the short rod are matched in shape, the length of the left clamping strip and the length of the auxiliary airbag are set to be equal, and the auxiliary airbags are provided in a group, and the auxiliary airbags in a group are bonded and connected by a group of double-sided tapes, and the double-sided tapes are set directly below the abutment between the left clamping strip and the right clamping strip.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, by providing a left clamping strip, an auxiliary airbag, a double-sided tape, a right clamping strip, a slot and a short rod, the clip-on heat shrinkable cable patch can facilitate the operation of tightening and limiting the sleeve by cooperating with the clamping strip and the lap clamp, respectively, by utilizing the clamping between the slot and the short rod, and a group of auxiliary airbags bonded together by a group of double-sided tape, to pre-limit the left clamping strip and the right clamping strip for docking, thereby reducing the number of times that the subsequent operator has to adjust and tighten a group of clamping strips multiple times. At the same time, by being able to perform auxiliary pre-limitation before installing the lap clamp, the difficulty of traditional installation of the lap clamp can be reduced, and the entire jacket installation operation is more convenient and labor-saving.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 , the utility model provides a technical solution:

[0020] A snap-on heat shrink cable patch comprises a heat shrinkable tube body 1, one side end of the heat shrinkable tube body 1 is provided with a left clamping strip 2 through integral molding, and the other side end of the heat shrinkable tube body 1 is provided with a right clamping strip 3 through integral molding, a slot 4 is provided at one side position inside the left clamping strip 2, a short rod 5 is provided at one side position of the right clamping strip 3 close to the left clamping strip 2 through integral molding, an auxiliary air bag 6 is bonded to the upper inner side of the heat shrinkable tube body 1, an air inlet plug 7 is provided below the auxiliary air bag 6, and a double-sided tape 8 is bonded to one side position of the auxiliary air bag 6.

[0021] like Figure 1 and Figure 2 As shown, a cable body 10 is provided at the middle position of the inner side of the heat shrinkable sleeve body 1, and the upper outer part of the cable body 10 is covered with a hot melt adhesive layer 9, and the hot melt adhesive layer 9 and the heat shrinkable sleeve body 1 are bonded and connected. When the heat shrinkable sleeve body 1 is heated with a low fire, the hot melt adhesive layer 9 will melt due to the heat, so that the heat shrinkable sleeve body 1 can be quickly bonded to the damaged part of the cable through the hot adhesive layer; the left clamping strip 2 and the right clamping strip 3 are respectively arranged in a columnar structure, and the outer part of the left clamping strip 2 and the right clamping strip 3 is clamped with an overlapping buckle body 11, and the outer part of the overlapping buckle body 11 is arranged in a "C"-shaped structure. After pre-defining the left clamping strip 2 and the right clamping strip 3, the overlapping buckle body 11 can be buckled on the outside of the left clamping strip 2 and the right clamping strip 3, so that the heat shrinkable sleeve body 1 is tightened and limited, and the heat shrinkable sleeve body 1 is prevented from loosening and falling from the damaged part of the cable.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the top surface of the overlapping buckle body 11 is provided with a notch 12 through integral molding, and the notch 12 is distributed in an equidistant structure along the horizontal direction. When the overlapping buckle body 11 is buckled on the outside of the left clip 2 and the right clip 3, the setting of the notch 12 mainly serves to assist the operator to observe whether the left clip 2 and the right clip 3 are accurately inserted into the inside of the overlapping buckle body 11; the shape between the inner end of the slot 4 and the outer end of the short rod 5 is matched, the length of the left clip 2 and the length of the auxiliary airbag 6 are set equal, and a group of auxiliary airbags 6 are provided, and a group of auxiliary airbags 6 are bonded and connected by a group of double-sided tapes 8. The double-sided tapes 8 are set just below the abutment between the left clip 2 and the right clip 3. Before using a group of auxiliary airbags 6, the air inlet plug 7 can be opened to inflate the inside of the auxiliary airbag 6 to make a group of auxiliary airbags 6 expand, so as to facilitate later bonding and limitation.

[0023] Working process: When using the buckle-type heat shrink cable repair piece, first, the damaged part of the cable can be cleaned and dusted on the surface, and at the same time, a group of auxiliary air bags 6 can be inflated. Then, the heat-insulating aluminum foil is affixed, and the heat-shrinkable tube body 1 is put on the outside of the damaged part of the cable. After the short rod 5 is inserted into the slot 4 in a centered manner, the isolation paper on the outside of the double-sided tape 8 can be removed, so that a group of auxiliary air bags 6 are bonded together by a group of double-sided tapes 8, and then the left clip 2 and the right clip 3 that need to be tightened upward at the same time are pre-defined. Then, under the pre-defined effect, the overlapping buckle body 11 can be buckled on the outside of the left clip 2 and the right clip 3 at the same time, so that the heat-shrinkable tube body 1 can be defined. Finally, a small fire is used to evenly heat the heat-shrinkable tube body 1 from the middle to the two sides, so that the entire heat pipe sleeve can be heated and shrunk, and the entire cable repair operation can be completed.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
