Description

Technical Field

[0001] The utility model relates to the technical field of insulating protection sleeves, in particular to an insulating protection sleeve for a wire interface. Background Technique

[0002] Insulating protection sleeves are used for the protection of the outside of electric wires and cables. According to material properties, they can be divided into four categories: single wire protection sleeves, composite wire protection sleeves, capacitive wire protection sleeves, and stainless steel protection sleeves. Insulating protection sleeves are mainly used for wrapping and protecting circuits. When installing conventional protection sleeves, it is necessary to first sleeved the insulating protection sleeve outside the wire, and then use connectors and terminal heads to install and fix the insulating protection sleeve. The installation process is relatively complex.

[0003] The application number is 201721367711.8, which discloses a bare wire insulating protection sleeve. The bare wire insulating protection sleeve includes a sleeve body and a plurality of clamping members for clamping the sleeve body. The sleeve body is buckled and sleeved on the bare wire, and a plurality of clamping members are evenly clamped on the sleeve body along the length direction of the sleeve body. The sleeve body includes a first arc section and a second arc section. One end of the first arc section and one end of the second arc section are integrally connected by extrusion. The other end of the first arc section and the other end of the second arc section are connecting blocks bent outward from the outside of the sleeve body. An arc-shaped isolation belt with high temperature resistance and insulation for separating the bare wire and the connecting block is provided on the inner wall of the first arc section. The purpose of the utility model is to provide a bare wire insulating protection sleeve that can prevent creepage, so as to solve the problem that the existing insulating sleeves are prone to creepage or breakdown of the insulating layer, resulting in accidents.

[0004] The insulating protection sleeve disclosed in the above document solves the problem that the existing insulating sleeves are prone to creepage or breakdown of the insulating layer, resulting in accidents. However, it has not made great improvements in the installation of the insulating protection sleeve. Therefore, it is necessary to design an insulating protection sleeve that is convenient for installation.

[0005] It can be seen that the existing insulating protection sleeves do not have the function of quick installation, and it is necessary to improve the existing deficiencies to provide a function of quick installation. Content of the Utility Model

[0006] The purpose of the utility model is to provide an insulating protection sleeve for a wire interface to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model relates to an insulating protection sleeve for a wire interface, which comprises a sleeve assembly and a fixing assembly. The sleeve assembly includes an upper sleeve and a lower sleeve. A fixing assembly is arranged inside the upper sleeve and the lower sleeve. Installation cavities are symmetrically formed inside the upper sleeve and the lower sleeve. A sliding groove is formed in the installation cavity. The fixing assembly includes an arc-shaped fixing block which is installed in the installation cavity. Two ends of the arc-shaped fixing block are fixedly connected with sliding blocks which are movably installed in the sliding groove. One end of the arc-shaped fixing block is connected with a spring, and the other end of the spring is connected to the inner wall of the installation cavity.

[0009] Further, a plurality of anti-slip bumps are uniformly arranged on the arc surface of the arc-shaped fixing block.

[0010] Further, connection blocks are symmetrically installed on the outer side of the upper sleeve. Two sides of the connection blocks are fixedly connected with limiting rods. Connection seats are symmetrically installed on the outer side of the lower sleeve. A limiting hole is formed in the middle of the connection seats. The limiting rods are movably installed in the limiting holes.

[0011] Further, an installation block is fixedly connected to the surface of the upper sleeve. Elastic limiting blocks are respectively arranged on two sides of the installation block.

[0012] Further, an installation groove is formed inside the lower sleeve. Limiting grooves are respectively formed on two sides inside the installation groove.

[0013] Further, insulating layers are arranged on the inner walls of the upper sleeve and the lower sleeve. An anti-oxidation layer is arranged inside the upper sleeve and the lower sleeve. Wear-resistant layers are arranged on the outer walls of the upper sleeve and the lower sleeve.

[0014] The utility model has the following beneficial effects:

[0015] (1) Through the arrangement of the arc-shaped fixing block, the sliding block, the sliding groove, the spring and the anti-slip bumps, during the merging process, the arc-shaped fixing block closely adheres to the wire surfaces on both sides of the joint. As the openings of the two half sleeves become smaller and smaller, the two arc-shaped fixing blocks start to move towards the inside of the installation cavity under the pressure of the wires, driving the sliding blocks to slide in the sliding grooves. At the same time, the arc-shaped fixing blocks slide inwards to compress the springs installed inside the installation cavity. The compressed springs continuously apply a force to the arc-shaped fixing blocks, enabling the arc-shaped fixing blocks to always closely adhere to the wire surfaces. Anti-slip bumps are arranged on the arc surfaces of the arc-shaped fixing blocks, which can increase the friction between the arc-shaped fixing blocks and the wires, and prevent the arc-shaped fixing blocks from sliding along the wire surfaces.

[0016] Certainly, when implementing any product of the utility model, it is not necessarily required to simultaneously achieve all the above-mentioned advantages. Description of the Drawings

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] Please refer to Figure 1 - Figure 6As shown in the figure, the utility model is an insulating protection sleeve for a wire interface, which includes a sleeve assembly 1 and a fixing assembly 2. The sleeve assembly 1 includes an upper sleeve 101 and a lower sleeve 102. The fixing assembly 2 is arranged inside the upper sleeve 101 and the lower sleeve 102. Installation cavities 111 are symmetrically opened inside the upper sleeve 101 and the lower sleeve 102. A chute 112 is opened in the installation cavity 111. The fixing assembly 2 includes an arc-shaped fixing block 201, which is installed in the installation cavity 111. Two ends of the arc-shaped fixing block 201 are fixedly connected with sliders 202, and the sliders 202 are movably installed in the chute 112. One end of the arc-shaped fixing block 201 is connected with a spring 203, and the other end of the spring 203 is connected to the inner wall of the installation cavity 111. The purpose of such a setting is that during the merging process, the arc-shaped fixing block 201 closely adheres to the surfaces of the wires on both sides of the joint. As the openings of the two half sleeves become smaller and smaller, the two arc-shaped fixing blocks 201 start to move towards the inside of the installation cavity 111 under the pressure of the wires, driving the sliders 202 to slide in the chute 112. At the same time, the arc-shaped fixing block 201 slides inwards and compresses the spring installed inside the installation cavity 111. The compressed spring continuously gives a force to the arc-shaped fixing block 201, enabling the arc-shaped fixing block 201 to always closely adhere to the surface of the wire. Anti-slip convex blocks 204 are arranged on the arc surface of the arc-shaped fixing block 201, and the anti-slip convex blocks 204 can increase the friction between the arc-shaped fixing block 201 and the wire, preventing the arc-shaped fixing block 201 from sliding along the surface of the wire.

[0028] A number of anti-slip convex blocks 204 are evenly arranged on the arc surface of the arc-shaped fixing block 201. The purpose of such a setting is to prevent the insulating protection sleeve from sliding on the wire surface.

[0029] Connection blocks 105 are symmetrically installed on the outer side of the upper sleeve 101. Two sides of the connection blocks 105 are fixedly connected with limit rods 106. Connection seats 109 are symmetrically installed on the outer side of the lower sleeve 102. A limit hole 110 is opened in the middle of the connection seats 109, and the limit rods 106 are movably installed in the limit holes 110.

[0030] Installation blocks 103 are fixedly connected to the surface of the upper sleeve 101, and elastic limit blocks 104 are respectively arranged on both sides of the installation blocks 103.

[0031] An installation groove 107 is opened inside the lower sleeve 102, and limit grooves 108 are respectively opened on both sides inside the installation groove 107. The purpose of such a setting is to fix the upper and lower sleeves.

[0032] Insulating layers 113 are arranged on the inner walls of the upper sleeve 101 and the lower sleeve 102. Anti-oxidation layers 114 are arranged inside the upper sleeve 101 and the lower sleeve 102. Wear-resistant layers 115 are arranged on the outer walls of the upper sleeve 101 and the lower sleeve 102. The purpose of such a setting is to extend the service life of the insulating protection sleeve.

[0033] During installation, first open this insulating protection tube sleeve, stick the lower sleeve 102 to the wire interface, then hold the upper sleeve 101 and close it downward. Under the action of the force, the limiting rod 106 rotates along the inner wall of the limiting hole 110. At this time, align the installation block 103 with the installation groove 107, and push the installation block 103 into the installation groove 107. The elastic limiting blocks 104 on both sides of the installation block 103 are compressed by the inner wall of the installation groove 107 under the action of the force and thus deform. Then, the elastic limiting blocks 104 slide along the inner wall of the installation groove 107 until the elastic limiting blocks 104 reach the position where the limiting groove 108 is located and then start to restore their shape and are fixed in the limiting groove 108, completing the combination of this insulating protection sleeve.

[0034] During the combination process, the arc-shaped fixing blocks 201 closely adhere to the wire surfaces on both sides of the joint. As the openings of the two half sleeves become smaller and smaller, the two arc-shaped fixing blocks 201 start to move into the installation cavity 111 under the pressure of the wires, driving the sliders 202 to slide in the sliding grooves 112. At the same time, the arc-shaped fixing blocks 201 slide inward and compress the spring installed inside the installation cavity 111. The compressed spring continuously gives a force to the arc-shaped fixing blocks 201, enabling the arc-shaped fixing blocks 201 to always closely adhere to the wire surfaces. Anti-slip convex blocks 204 are arranged on the arc surfaces of the arc-shaped fixing blocks 204, and the anti-slip convex blocks 204 can increase the friction between the arc-shaped fixing blocks 201 and the wires, preventing the arc-shaped fixing blocks 201 from sliding along the wire surfaces.

[0035] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific embodiments described. Obviously, many modifications and variations can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the relevant technical field can well understand and utilize the present utility model. The present utility model is only limited by the claims and their full scope and equivalents.
