Abstract

This invention discloses a coaxial cable adapter with a cooling structure and its sealing method, solving the problem of prolonged high-temperature heating during the sealant potting and curing process affecting the transmission performance of coaxial cables.

The cooling medium circulates through the heat dissipation pipes, absorbing and carrying away the heat generated during sealant curing under forced convection, enhancing the convective heat dissipation effect, achieving sealant potting and cooling treatment, and avoiding the impact of prolonged high-temperature environments on the transmission performance of coaxial cables.

Description

Technical Field

[0001] This invention relates to a coaxial cable adapter and its sealing method, specifically to a coaxial cable adapter with a cooling structure and its sealing method. Background Technology

[0002] In the field of cable adapters, coaxial cable adapters are typically installed at cable relay points and equipment interface ends to meet requirements such as coaxial interface compatibility, ensuring stable signal transmission, extending signal transmission distance, or adapting to different installation scenarios. After the coaxial cable adapter is installed, it needs to be sealed with sealant to effectively fill any tiny gaps that may exist after installation, while also securing the coaxial cable and strengthening the seal and protection of the cable.

[0003] In the sealing process of coaxial cable adapters, for applications requiring rapid completion, two-component sealants are typically used. While these sealants cure quickly, they generate a significant amount of heat. For example... Figure 1 , Figure 2 As shown in the figure, actual measurements indicate that during the potting process using two-component sealant, the highest temperature can reach 90 degrees Celsius, and the high temperature caused by heat will exceed the maximum operating temperature of the coaxial cable for approximately one hour. Prolonged exposure to high temperatures will significantly reduce the transmission performance of the coaxial cable. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problem that the coaxial cable is exposed to a high temperature environment for a long time during the existing sealant potting process, which leads to a decrease in its transmission performance. The invention provides a coaxial cable adapter with a cooling structure and its sealing method.

[0005] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0006] A coaxial cable adapter with a cooling structure includes a cable reel and a glue-filling cylinder located on the cable reel. The cable reel is used to install multiple coaxial cables passing through the glue-filling cylinder. Its special feature is that it also includes a cooling component. The cooling component includes heat dissipation pipes disposed inside the glue-filling cylinder.

[0007] The heat dissipation piping includes an upper heat exchange piping, a lower heat exchange piping, connecting piping, a cooling medium inlet piping, and a cooling medium outlet piping;

[0008] Both the upper and lower heat exchange pipelines include N arc-shaped pipelines connected end-to-end to form a series upper and lower heat exchange loops. The N arc-shaped pipelines in each layer are distributed at intervals from the inside to the outside along the radial direction of the glue-filling cylinder in the same horizontal plane, so as to divide the inner cavity of the glue-filling cylinder into N or N+1 layers along its radial direction. The upper and lower heat exchange loops are connected by connecting pipelines. Multiple coaxial cables are distributed in the N or N+1 layers; where N≥2.

[0009] The outer end of the cooling medium inlet pipe is used to connect to an external cooling medium source, and its inner end is connected to the inlet of the lower heat exchange circuit.

[0010] The outer end of the cooling medium outlet pipe is used to discharge the cooled medium after heat exchange, and its inner end is connected to the outlet of the upper heat exchange circuit.

[0011] Furthermore, the cooling component also includes multiple heat sinks;

[0013] Multiple heat sinks are respectively installed in corresponding heat sink mounting positions, with their inner wall surfaces abutting against the outer wall surfaces of the glue-filling cylinder for heat conduction, and their outer wall surfaces used for heat dissipation.

[0014] Furthermore, the glue-dispensing cylinder includes a cylinder body and an upper flange and a lower flange respectively connected to the upper and lower ends of the cylinder body;

[0015] The outer peripheral wall of the cylinder body is provided with multiple equally spaced strip partitions. The upper end of each strip partition is connected to the upper flange, and the lower end is connected to the lower flange to form a heat dissipation block mounting position.

[0016] Each heat sink is installed in its corresponding heat sink mounting position, with its upper end connected to the upper flange. Each heat sink has a heat-conducting side and a heat-dissipating side from the inside out. The size of its heat-conducting side is adapted to the heat sink mounting position and is used to conduct heat on the glue-filling cylinder. Its heat-dissipating side has multiple strip-shaped fins for heat dissipation.

[0017] Furthermore, the cooling assembly also includes multiple vertical fixing rods and pipe supports;

[0018] The N arc-shaped pipes of the upper heat exchange pipeline are connected one-to-one with the N arc-shaped pipes of the lower heat exchange pipeline through vertical fixing rods.

[0019] The lower end of the pipe support has an arc-shaped section for accommodating the outermost arc-shaped upper heat exchange pipe, and the upper end has a bent section for overlapping the top of the glue-filling cylinder so that the heat dissipation pipe is supported and set in the inner cavity of the glue-filling cylinder.

[0020] Furthermore, the cooling assembly also includes multiple lateral fixing rods;

[0021] Two adjacent arc-shaped pipes located in the upper and lower heat exchange pipes are connected by a horizontal fixing rod.

[0022] Furthermore, the heat dissipation pipeline also includes a plug and a first sealing gasket;

[0023] The outer ends of the cooling medium inlet pipe and the cooling medium outlet pipe are sealed by plugs and first sealing gaskets, respectively.

[0024] Furthermore, the heat dissipation pipeline also includes multiple pipeline adapter components;

[0025] Each of the aforementioned pipe transition assemblies includes a bend, connectors disposed at both ends of the bend, and a second sealing gasket disposed inside the connector;

[0026] The two ends of the bend are respectively provided with connecting steps, each connecting step having a thin section and a thick section connected to the thin section, and one end of the thin section is connected to the end face of the two ends of the bend respectively.

[0027] Each of the connectors has a limiting step at one end, which engages with the connection between the thin and thick sections of the connecting step, so that each connector can be rotatably connected to the corresponding bend.

[0028] The other end of each connector is threaded to its corresponding arc-shaped pipe, or to its corresponding connecting pipe, or to its corresponding cooling medium inlet pipe or cooling medium outlet pipe.

[0029] Each of the second sealing gaskets is located within each of the connectors, with one end abutting against the end face of the thicker section of the connecting step away from the thinner section, and the other end abutting against the end face of the arc-shaped pipe, or the connecting pipe, or the cooling medium inlet pipe and the cooling medium outlet pipe, to seal the corresponding connection interface.

[0030] Meanwhile, the present invention also provides a sealing method for a coaxial cable adapter with a cooling structure, which is characterized by including the following steps:

[0031] Step 1: Construct the coaxial cable adapter with the cooling structure described above;

[0032] Step 2: Install multiple coaxial cables onto the cable reel and distribute them in each layer area;

[0033] Step 3: Connect the outer end of the cooling medium inlet pipe to the external cooling medium source, and connect the outer end of the cooling medium outlet pipe to the external return pipe to form a heat exchange loop;

[0034] Step 4: Start the cooling medium source to fill the heat exchange circuit with cooling medium;

[0035] Step 5: Pour the preset amount of sealant into the dispensing tube and allow it to cure until the sealant no longer flows.

[0036] Step 6: Repeat step 5 until the glue-filling cartridge is fully sealed;

[0037] Step 7: After the preset curing time, allow all sealant to cure completely, turn off the cooling medium source, and disassemble the cooling medium source, return pipeline, and heat sink to complete the sealing of the coaxial cable adapter with cooling structure.

[0038] Furthermore, the cooling medium source in step 3 is a cooling water source.

[0039] Furthermore, in step 5, the preset mass is 20%-25% of the total adhesive used.

[0040] Compared with the prior art, the present invention has the following beneficial technical effects:

[0041] 1. The present invention provides a coaxial cable adapter with a cooling structure. By setting up heat dissipation pipes, the inner cavity of the glue-filling cylinder is divided into N or N+1 layers along its radial direction. Multiple coaxial cables are distributed in each layer. During the glue-filling and sealing process, a flowing cooling medium is filled into the heat dissipation pipes. Under forced convection conditions, the heat generated during the curing process of the sealant is carried away, thereby enhancing the convection heat dissipation effect and realizing the cooling treatment of the sealant during potting. This avoids the impact of long-term high-temperature environment on the transmission performance of the coaxial cable.

[0042] 2. The present invention provides a coaxial cable adapter with a cooling structure. By adding a heat sink and setting multiple strip fins on the heat sink side, the heat dissipation area of ​​the glue-filling cylinder is increased, allowing more heat to be transferred to the surrounding air and enhancing the passive convection cooling effect.

[0043] 3. The present invention provides a coaxial cable adapter with a cooling structure. By setting vertical and horizontal fixing rods, the stability of the heat dissipation pipe is improved. By setting pipe supports, the heat dissipation pipe is supported in the inner cavity of the glue-filling cylinder, so that the heat dissipation pipe is located in the core heat dissipation area of ​​the glue-filling cylinder, thereby improving heat dissipation efficiency.

[0044] 4. The present invention provides a coaxial cable adapter with a cooling structure. By setting a pipeline adapter assembly, the connector and both ends of the bend are rotatably connected, which facilitates the connection of the connector with its corresponding arc-shaped pipeline, connecting pipeline, cooling medium inlet pipeline and cooling medium outlet pipeline, thus ensuring the cooling effect.

[0045] 5. The present invention provides a sealing method for a coaxial cable adapter with a cooling structure. By installing heat sinks and heat dissipation pipes, the method achieves cooling during the sealant potting process. Furthermore, by potting the sealant in multiple layers, the total amount of heat source is reduced, thereby lowering the maximum temperature during sealant curing. This avoids the impact of prolonged high-temperature environments on the transmission performance of the coaxial cable, thus ensuring the reliability of the coaxial cable transmission performance.

One end of one of the semi-annular clips 92 is fixedly connected to the upper end of the vertical rod 91, which can be welded or integrally formed. One end of the other semi-annular clip 92 is hinged to the upper end of the vertical rod 91 by the first screw 93 and the first nut 94.

[0085] The specific process of installing the heat dissipation pipe 8 inside the glue-filling cylinder 3, so that multiple coaxial cables 2 are distributed in each layer area, can be achieved by first connecting the heat dissipation pipe 8, then passing the free ends of multiple coaxial cables 2 through each layer area in sequence, then putting on the glue-filling cylinder 3, installing multiple coaxial cables 2 onto the cable reel 1, and then placing the heat dissipation pipe 8 inside the glue-filling cylinder 3.

[0089] Step 4: Start the cooling medium source to fill the heat exchange circuit with flowing cooling medium. In this embodiment, the cooling medium source is a cooling water source and the cooling medium is condensate.

[0090] Step 5: Pour a preset amount of sealant into the glue-pouring cylinder 3, so that it completely wraps each coaxial cable 2, and cures until the currently poured sealant no longer flows; in this embodiment, the preset amount is 20%-25% of the total amount of glue used.

[0091] Step 6: Repeat step 5 until the filling of the glue-filling cartridge 3 is complete;

[0092] Step 7: After the preset curing time, allow all sealant to cure completely, shut off the cooling medium source, and disassemble the cooling medium source, return pipeline, and heat sink 7. Finally, use the plug 86 and the first sealing gasket 87 to seal the heat dissipation pipeline, thus completing the sealing of the coaxial cable adapter with a cooling structure.
