Description

Technical Field

[0001] This utility model relates to the field of automotive cable technology, and in particular to an automotive cable sleeve. Background Technology

[0002] Automotive cables are used for power transmission, signal transmission, and control in automobiles, and are one of the important components of automotive electrical systems. They are specially designed and manufactured according to the needs of automobiles, and have functions such as heat resistance, cold resistance, abrasion resistance, oil resistance, and interference resistance to ensure driving safety.

[0003] Automotive cables are susceptible to environmental factors, mechanical stress, chemical corrosion, and external damage during use, leading to cracking and wear. To extend the lifespan of automotive cables, regular inspection and replacement of aging cables are necessary. For minor wear or cracks in the outer sheath, insulating tape can usually be used to wrap the cracks or easily worn areas to protect the cable and prevent further damage. However, it's important to note that after insulating tape is wrapped around the cable, on the one hand, prolonged exposure to air or the pipeline's radiation can cause the adhesive and other components in the tape to oxidize or decompose, resulting in a loss of stickiness. On the other hand, in environments with high or low temperatures or high humidity, the adhesive and sticky substances in the tape can become softer or more brittle, leading to a decrease in tape stickiness, tape separation, and loss of adhesion, making it unable to tightly wrap the cable and effectively protect it.

[0004] In addition, an insulating protective sleeve can be installed over the cable to protect it. However, since both the insulating protective sleeve and the cable are made of high-friction materials, the relative friction between the insulating protective sleeve and the cable is large when the insulating protective sleeve moves from the moving end of the cable to the damaged or worn position. This makes it difficult for users to install the insulating protective sleeve quickly.

[0005] Therefore, designing a car cable protection sleeve that can solve the above-mentioned technical problems is a technical issue that needs to be addressed. Utility Model Content

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0028] See Figure 1-3As shown, the scheme includes an inner housing 1, an insulating protective sleeve 2 movably fitted on the outer peripheral wall of the inner housing 1, an outer housing 3 placed on the outer peripheral wall of the insulating protective sleeve 2 to cooperate with the inner housing 1, and several limiting components 4 disposed between the inner housing 1 and the outer housing 3 for adjusting the position of the insulating protective sleeve 2; the inner diameter of the inner housing 1 is larger than the outer diameter of the wire and cable, so that the inner housing 1 can move flexibly on the surface of the wire and cable.

[0029] The inner housing 1 includes an upper connecting housing 11 and a lower connecting housing 12 detachably connected to the upper connecting housing 11; the upper connecting housing 11 and the lower connecting housing 12 are symmetrically provided with first limiting grooves 111 on the left and right sides of the front end face of the housing, and the corresponding positions of the first limiting grooves 111 on the rear end face of the housing are symmetrically provided with second limiting grooves 112 that match the shape and size of the first limiting grooves 111;

[0030] The mounting housing 3 includes an upper housing 31 and a lower housing 32 detachably connected to the upper housing 31; the left and right sides of the front end face of the upper housing 31 and the lower housing 32 are symmetrically provided with a third limiting groove 311 that matches the shape and size of the first limiting groove 111; the corresponding position of the third limiting groove 311 on the rear end face of the upper housing 31 and the lower housing 32 is symmetrically provided with a fourth limiting groove 312 that matches the shape and size of the first limiting groove 111.

[0031] Several limiting components 4 are respectively disposed between the first limiting groove 111 and the second limiting groove 112, the third limiting groove 311 and the fourth limiting groove 312 on opposite sides; each of the limiting components 4 includes a support rod 41 movably disposed between the inner peripheral wall of the insulating protective sleeve 2 and the mounting inner shell 1, a first connecting rod 42 movably disposed at the front and rear ends of the support rod 41, a second connecting rod 43 vertically fixed at the outer end of the first connecting rod 42, and a second connecting rod 43 vertically fixed at the inner side of the second connecting rod 43 and the first limiting groove 111. 1. A limiting block 44 with a matching shape and size; the front and rear ends of the support rod 41 are provided with mounting grooves 411 that match the first connecting rod 42. The mounting groove 411 has a first movable sliding groove 4111 symmetrically provided along its length on the groove wall. A second movable sliding groove 4112 is provided around the circumference of the mounting groove 411 at one end opposite to the groove opening of the mounting groove 411. A limiting post 421 that cooperates with the first movable sliding groove 4111 is vertically fixed to the outer peripheral wall of the inner end of the first connecting rod 42. The lengths of the limiting post 421, the first limiting groove 111, the second limiting groove 112, the third limiting groove 311, and the fourth limiting groove 312 are adjusted according to the actual situation so that the support rod 41 can support the insulating protective sleeve 2.

[0032] Furthermore, the upper connecting shell 11 has a first connecting groove 113 formed on both the left and right end faces along its length direction, and the lower connecting shell 12 has a first slider 121 that matches the first connecting groove 113 vertically fixed on both the left and right end faces.

[0033] Furthermore, the upper outer shell 31 has a second connecting groove 313 on both the left and right end faces along its length direction, and the lower outer shell 32 has a second slider 321 that matches the shape and size of the first connecting groove 113 on both the left and right end faces.

[0034] Furthermore, a first connecting groove 114 is provided on the upper outer shell 31, and a second connecting groove 314 is provided on the upper connecting shell 11 at a position opposite to the first connecting groove 114. A plug 5 is detachably provided between the first connecting groove 114 and the second connecting groove 314.

[0035] The working principle is roughly as follows:

[0036] First, pass the movable inner housing 1 through the movable end of the cable and move it to the position where the cable is worn, and remove the plug 5 between the upper connecting housing 11 and the upper outer housing 31;

[0037] Secondly, in the initial state, such as Figure 1 As shown, the limiting blocks 44 of each limiting component 4 are respectively inserted into the corresponding first limiting groove 111, second limiting groove 112, third limiting groove 311, and fourth limiting groove 312. During operation, the first connecting rods 42 on each side are moved in sequence, as follows: First step: Move the first connecting rod 42 outward, while the limiting post 421 at the bottom of the first connecting rod 42 moves outward along one side of the first sliding groove until the first connecting rod 42 moves to the outermost position, the limiting block 44 moves out of the first limiting groove 111, and the limiting post 421 is placed in the second connecting sliding groove 313; Second step: Rotate the first connecting rod 42 circumferentially 180° so that the limiting post 421 is vertically upward, and the limiting post 421 at the bottom of the first connecting rod 42 moves into the first connecting sliding groove 113 on the other side. Figure 2 As shown; the third step: push the first connecting rod 42 inward again, so that the limiting post 421 at the bottom of the first connecting rod 42 moves inward along the first limiting groove on the other side, and at the same time the limiting post 421 inserts into the corresponding third limiting groove 311; after operating the first connecting rod 42 on each side in sequence as described above, the insulating protective sleeve 2 is placed between the limiting component 4 and the mounting shell 3. Under the support of the support rod 41 and the elasticity of the insulating protective sleeve 2, the insulating protective sleeve 2 moves from being tightly attached to the outer peripheral wall of the mounting inner shell 1 to being relatively close to the movable inner shell.

[0038] Finally, the upper connecting shell 11 and the lower connecting shell 12 are moved relative to each other from both sides, and separated and removed from each other through the first connecting groove 113 and the first slider 121; then the first connecting rod 42 is moved outward so that it moves out of the third limiting groove 311 (or the fourth limiting groove 312); the upper outer shell 31 and the lower outer shell 32 are moved relative to each other from both sides, and separated and removed from each other through the second connecting groove 313 and the second slider 321. Simultaneously, the connection between the limiting post 421 and the fourth limiting groove 312 (or the third limiting groove 311) allows the upper outer shell 31 and the lower outer shell 32 to be separated and removed, while the lower side of the support rod 41 and the total insulating protective sleeve 2 are brought out (since the contact area between the support rod 41 and the cable and the insulating protective sleeve 2 is small, it is much easier to move the support rod 41 from below the insulating protective sleeve 2 than to move the insulating protective sleeve 2 on the surface of the cable), so that the insulating protective sleeve 2 is tightly fitted onto the outer wall of the wire and cable.

Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
