Description

Technical Field

[0001] This utility model belongs to the field of joint sealing technology, specifically relating to a sealing structure for cable fusion splice joints. Background Technology

[0002] A fusion splice is a permanent joint that uses localized heating to melt or smelt the ends of two cables to complete the connection, forming a continuous cable. In use, cables are connected using fusion splices to link them together.

[0003] A search revealed application number 202321352134.0, which discloses a sealing structure for a cable fusion splice joint. The structure includes a first device body and a second device body externally. A first sealing ring and a second sealing ring are respectively provided on the exterior of both the first and second device bodies. Insertion holes are formed on the exterior of each sealing ring, and a plug rod is connected to the interior of each insertion hole via an inlay. A limiting block is fixedly connected to the exterior of the plug rod, and the limiting block is fitted against the exterior of the first and second sealing rings. This cable fusion splice sealing structure, by providing the first and second sealing rings at the connection point of the first and second device bodies, prevents rainwater and snowflakes from penetrating the interior of the connection point through gaps, thus greatly improving the sealing performance.

[0004] In the above technical solution, the first sealing ring and the second sealing ring are connected by inserting a rod into the socket. The direct insertion of the rod into the socket can easily cause the rod to detach, which can lead to the first sealing ring and the second sealing ring falling off, resulting in poor overall product fixation. Utility Model Content

[0005] The purpose of this invention is to provide a sealing structure for cable fusion joints to solve the problem of sealing ring fixation performance in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable fusion splice sealing structure includes a fusion splice conductor, two protective plates detachably installed at the welding point of the fusion splice conductor, and the two protective plates are assembled together; the side wall of the protective plate is provided with a positioning component; the inner wall of the protective plate is provided with an inner reinforcement component; and the outer wall of the protective plate is provided with an outer reinforcement component.

[0008] Preferably, the positioning component includes a slot and a connecting block. The slot is located on the side of the protective plate, and the connecting block has a central column that is concentrically fitted with the slot on one side.

[0009] Preferably, the slot has a positioning hole with the opening facing the outer wall of the protective plate, and a ball is installed at the front end of the spindle, with a spring connected to the bottom of the ball.

[0010] Preferably, the internal reinforcement component includes a built-in groove and an airbag. The built-in groove is centrally and symmetrically arranged on the inner wall of the protective plate, and the airbag has an input nozzle that protrudes through the built-in groove onto the outer wall of the protective plate.

[0011] Preferably, the contact surface between the airbag and the fusion splice wire is made of an anti-slip material. The addition of this anti-slip material further improves the stability of the airbag's contact with the fusion splice wire, preventing the fusion splice wire from shifting.

[0012] Preferably, the external reinforcement components are symmetrically distributed on the outer wall of the protective plate. The external reinforcement components include a middle block and side blocks. The middle block is fixed in the middle part of the outer wall of the protective plate, and the side blocks are distributed on both sides of the middle block. Curved holes are provided on both the middle block and the side blocks.

[0013] Preferably, the side block is also provided with parallel holes. After the binding line is tightened, a bolt is inserted into the parallel hole and passes through the side block on both protective plates. The other end of the bolt is tightened with a nut to further improve the overall stability.

[0014] The technical solution of this utility model has the following beneficial effects:

[0015] 1. After aligning the two protective plates, insert the mandrel into the slot, that is, the two mandrels are located in the slots of the two protective plates respectively, so as to achieve initial positioning and facilitate further stabilization of the two protective plates.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] Example 1:

[0028] refer to Figures 1-3 A cable fusion splice sealing structure includes a fusion splice conductor 10, and two protective plates 20 are detachably installed at the welding point of the fusion splice conductor 10, and the two protective plates 20 are assembled together.

[0029] The protective plate 20 has positioning components on its side wall;

[0030] The positioning components include a slot 201 and a connecting block 203. The slot 201 is opened on the side of the protective plate 20, and the connecting block 203 has a symmetrical central column 204 that is concentrically engaged with the slot 201 on one side.

[0031] The fusion splice wire 10 is the wire after the fusion splice is completed. Two protective plates 20 are installed at the fusion splice position. After the two protective plates 20 are aligned, the spindle 204 is inserted into the slot 201. That is, the two spindles 204 are located in the slots 201 of the two protective plates 20 respectively, so as to achieve initial positioning and facilitate further stabilization of the two protective plates 20. It should be noted that there are four slots 201 in total, which are symmetrical vertically and horizontally.

[0032] Preferred Solution Reference Figure 2 and Figure 3The slot 201 has a positioning hole 202 with the opening facing the outer wall of the protective plate 20. A ball 205 is installed at the front end of the spindle 204, and a spring 206 is connected to the bottom of the ball 205.

[0033] In the preferred embodiment, when both spindles 204 are fully inserted into the slots 201, their spheres 205 will spring up under the influence of the spring 206. The spheres 205 then press against the inside of the positioning hole 202, making it difficult for the spindles 204 to fall out of the slots 201, thus further improving the stability of the spindles 204. After removing the spindles 204 again, press the spheres 205 down from inside the positioning hole 202 to move them out of the hole, and then pull out the spindles 204 to easily remove the two protective plates 20.

[0034] Example 2:

[0035] refer to Figure 2 and Figure 5 The inner wall of the protective plate 20 is provided with internal reinforcement components;

[0036] The internal reinforcement components include an internal groove 40 and an airbag 401. The internal groove 40 is centrally and symmetrically arranged on the inner wall of the protective plate 20. The airbag 401 has an input nozzle 402 that passes through the internal groove 40 and protrudes from the outer wall of the protective plate 20.

[0037] In the above scheme, the air valve 402 is a standard air valve 402 commonly used on bicycles or electric vehicles. An air pump or cylinder connects to the air valve 402 to supply air into the air bag 401. The air bag 401 presses against the outer wall of the fusion splice wire 10, preventing wear on the inner wall of the protective plate 20 and protecting the circuit. Simultaneously, the inflated air bag 401 exerts an outward force on the protective plate 20, which, combined with the positioning of the spindle 204, keeps both protective plates 20 in a taut state, preventing positional displacement and enhancing the protection of the fusion splice wire 10. The air valve 402 needs to be tightened by screwing on the cap, which is not shown in the diagram.

[0038] In the preferred embodiment, the contact surface between the airbag 401 and the welding wire 10 is provided with an anti-slip material. The addition of this anti-slip material further improves the stability of the contact between the airbag 401 and the welding wire 10, preventing the welding wire 10 from shifting and further refining the overall technical solution.

[0039] Example 3:

[0040] refer to Figures 4-7 The outer wall of the protective plate 20 is equipped with external reinforcement components;

[0041] The external reinforcement components are symmetrically distributed on the outer wall of the protective plate 20. The external reinforcement components include a middle block 30 and an edge block 301. The middle block 30 is fixed in the middle part of the outer wall of the protective plate 20, and the edge blocks 301 are distributed on both sides of the middle block 30. Curved holes 303 are provided on both the middle block 30 and the edge blocks 301.

[0042] In the above scheme, the inside of the curved hole 303 is the same as the winding binding line 304. The binding line 304 can be a nylon plastic cable tie or a thin steel wire. By passing the binding line 304 through the middle block 30 and the side block 301 in sequence, the binding line 304 is locked to achieve the stability of the two protective plates 20.

[0043] Example 4:

[0044] refer to Figure 5 Parallel holes 302 are also provided on the edge block 301.

[0045] After the binding line 304 is locked, a bolt (not shown in the figure) is inserted into the parallel hole 302 and passes through the side block 301 on both protective plates 20. The other end of the bolt is locked with a nut to further improve the overall stability.

[0046] In summary, it should be noted that the use of the binding wire 304 and the bolts inserted into the parallel holes 302 can achieve the desired fixation by using either one alone or in combination of both. Furthermore, after the two protective plates 20 are reinforced by the binding wire 304 or the bolts inserted into the parallel holes 302, gas is then injected into the airbag 401 to balance the internal and external forces, further improving the overall functionality. The external reinforcement components can support the protective plates 20 on the ground, preventing direct contact and wear, and extending their service life.

[0047] The specific implementation process of this utility model is as follows:

[0048] Two protective plates 20 are installed at the welding position. After the two protective plates 20 are aligned, the spindle 204 is inserted into the slot 201. That is, the two spindles 204 are located in the slots 201 of the two protective plates 20 respectively, thus achieving initial positioning.

[0049] The stability of the two protective plates 20 is achieved by passing the binding line 304 through the middle block 30 and the side block 301 in sequence and locking the binding line 304; or by inserting a bolt into the parallel hole 302 and passing it through the side block 301 on both protective plates 20 at the same time, and locking the other end of the bolt with a nut.

[0050] Air is supplied to the airbag 401 through the air pump or air cylinder into the air nozzle 402. The airbag 401 will press against the outer wall of the fusion splice wire 10 to prevent the fusion splice wire 10 from being worn on the inner wall of the protective plate 20 and to protect the circuit.

[0051] The above embodiments are merely exemplary models of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions can be made to this utility model within its substance and scope of protection.
