Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cold shrink cable finger sleeve. Background Art

[0002] Cold-shrink cable finger sleeves are a type of cold-shrink cable accessory used for cable connection. They utilize cold-shrink technology, requiring no open flame or special tools for installation. Simply pull out the cable core, and the elastic rapidly shrinks to fit snugly within the desired installation area. The sleeves automatically shrink and wrap around the cable, creating a plastic coating and isolating it from the outside world, greatly simplifying the installation process. However, during storage and transportation, cold-shrink cable finger sleeves can be subject to external forces, causing the sleeves to separate from the supporting tube. This can cause the sleeves to shrink and deform prematurely at the separation point, impacting their usability. Utility Model Content

[0003] In view of the above-mentioned technical problems, the purpose of the present invention is to provide a cold-shrink cable finger sleeve to avoid premature deformation when not in use.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] Preferably, the support tube and the finger tube are both formed by spirally winding continuous wire, a drawstring connected to one end of the wire is provided in the support tube, and a notch for the drawstring to pass through is provided on the inner support member.

[0007] Preferably, the cover is disc-shaped and is provided with a circular feature portion corresponding to the vial. When the card block enters the insertion port, the projection of the feature portion on the first end face is concentric with the vial.

[0008] Preferably, the cross section of the block is square or circular.

[0009] Preferably, during the rotation of the insertion rod, the side surface of the lower cavity is always in contact with the blocking block.

[0010] Preferably, the cap fits snugly over the end of the vial.

[0011] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0012] The utility model discloses a cold shrink cable finger sleeve comprising a finger sleeve body and an inner support member and an outer connection member detachably connected to the finger sleeve body. The inner support member is placed in the support tube so that the auxiliary tube is inserted into the finger tube and the second end face is fitted with the first end face. The cylinder body and the auxiliary tube play a supporting and reinforcing role for the support tube and the finger tube to avoid deformation due to force. After the characteristic part of the outer connection member is aligned with the finger tube, force is applied to make the insertion rod pass through the insertion port and enter the lower cavity. The cover body is rotated to make the clamping block enter the interior of the lower cavity. The inner support member and the outer connection member are connected to further stabilize the finger tube, thereby preventing the finger tube from being separated from the support tube, causing the cold shrink sleeve to shrink and deform prematurely and affect use, thereby improving the quality of the finger sleeve.

[0024] As attached Figure 1 The utility model shows a cold shrink cable finger sleeve, which includes a finger sleeve body and an inner support member 5 and an outer connecting member 6 detachably connected to the finger sleeve body. Figure 2 As shown, the finger sleeve body includes a support tube 1, which includes a first end surface 2. At least three finger vials 3 are connected to the first end surface 2 and are evenly distributed around the axis of the support tube 1. The support tube 1 and the finger vials 3 are covered with a cold shrink sleeve 4, and the ends of the support tube 1 and the finger vials 3 are exposed outside the cold shrink sleeve 4.

[0025] As attached Figure 5 As shown, the external connecting member 6 includes a cover body 61, one side of which is connected to an insertion rod 62 whose number and position correspond to the finger vial 3, and the end of the insertion rod 62 is connected to a clamping block 63, and the cross-sectional area of ​​the clamping block 63 is larger than the cross-sectional area of ​​the insertion rod 62.

[0026] As attached Figure 6 , Attachment Figure 7As shown, the inner support member 5 includes a cylinder 51 installed in the support tube 1, the cylinder 51 includes a second end face 52 that is in contact with the first end face 2, and a sub-tube 53 is formed on the second end face 52 to be inserted into the finger tube 3. The sub-tube 53 has a cavity therein, and the cavity includes an upper cavity 54 that is connected to the surface of the second end face 52 and a lower cavity 55 located inside the second end face 52. The upper cavity 54 includes an insertion port 541 and a track 542. The shape of the insertion port 541 corresponds to the shape of the block 63, and the width of the track 542 corresponds to the diameter of the insertion rod 62. The track 542 is an arc track 542 that surrounds the axis of the support tube 1. As shown in the attached figure Figure 3 , Attachment Figure 4 As shown, the clamping block 63 is inserted through the upper cavity 54 into the lower cavity 55 and the insertion rod 62 is rotated along the track 542 by an angle, so that the inner support member 5 and the outer connecting member 6 are engaged and connected, and the cover body 61 fits with the end of the finger vial 3, forming a connected support body between the support tube 1 and the finger vial 3, thereby increasing the overall strength and preventing the finger vial 3 from being separated from the support tube 1 due to external force, thereby preventing the shrink sleeve 4 from deforming and shrinking.

[0027] The support tube 1 and the finger tube 3 are both formed by spirally winding continuous wire. A drawstring connected to one end of the wire is provided in the support tube 1, and a notch is provided on the inner support member 5 for the drawstring to pass through.

[0028] The cover 61 is disc-shaped and has a circular feature 611 formed thereon that corresponds to the vial 3. When the block 63 enters the insertion opening 541, the projection of the feature 611 on the first end surface 2 is concentric with the vial 3, facilitating positioning and quick alignment of the block 63 with the insertion opening 541. The cross-section of the block 63 is square or circular. During rotation of the insertion rod 62, the side of the lower cavity 55 remains in contact with the block 63, ensuring a tight connection and preventing loosening.

[0029] When storage and transportation are required, the inner support member 5 is placed within the support tube 1, with the auxiliary tube 53 inserted into the vial 3 and the second end face 52 aligned with the first end face 2. The diameter of the cylinder 51 is slightly smaller than that of the support tube 1, and the diameter of the auxiliary tube 53 is slightly smaller than that of the vial 3. The cylinder 51 and auxiliary tube 53 provide support and reinforcement for the support tube 1 and the vial 3, preventing them from deforming under stress. Aligning the characteristic portion 611 of the outer connector 6 with the vial 3, force is applied to force the insertion rod 62 through the insertion opening 541 and into the lower cavity 55. The cover 61 is rotated to allow the retaining block 63 to enter the lower cavity 55. This connects the inner support member 5 and the outer connector 6, further stabilizing the vial 3 and preventing the vial 3 from separating from the support tube 1, which could cause the shrink sleeve 4 to shrink and deform prematurely and affect its use. When use is required, the cover 61 is rotated in the opposite direction to remove the insertion rod 62, separating the inner support member 5 and the outer connector 6.

[0030] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
