Technical Field

[0001] This invention relates to the field of cable technology, and more specifically, to a cable repeater assembly. Background Art

[0002] In existing technologies, the common method for outdoor cable wiring is to crimp tubular terminals, cover them with insulating tape, and then wrap them with cold-shrink tubing. However, this cable wiring method has a long construction period, and the components cannot be reused when reconnecting.

[0003] In summary, how to provide a device that can quickly complete wiring work and improve the utilization rate of parts is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a cable repeater assembly that can quickly complete wiring work and effectively improve the utilization rate of parts and reduce the operating cost of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cable repeater assembly includes: terminals, an insulating sheath for fixing and protecting the terminals, and a main body for fixing and protecting the sheath. The sheath includes a terminal sleeve that is detachable and splicable along the axial direction for fixing the terminals. The terminals are disposed within the sheath, and the sheath is disposed within the main body. Both the sheath and the main body have through holes at their axial ends for allowing a cable to pass through and contact the terminals. The main body has sealing devices at its axial ends for sealing and locking the cable.

[0007] Preferably, the terminal sleeve has a protrusion in the middle for axially fixing the terminal, and the protrusion matches the shape and size of the terminal.

[0008] Preferably, both ends of the terminal sheath are provided with bosses for axially fixing the cable.

[0009] Preferably, the sheathing device includes an insulating sleeve for fixing and protecting the terminal sheath, the terminal sheath being disposed inside the insulating sleeve, and the insulating sleeve being disposed inside the main body device.

[0010] Preferably, the main body device is provided with a foolproof stop to ensure the uniqueness of the assembly direction, and the sheath device is provided with a mounting position for cooperating with the foolproof stop to form a unique assembly direction.

[0011] Preferably, the outer side of the main device is coated with fluorescent paint to facilitate nighttime maintenance operations.

[0012] Preferably, the sealing device includes a sealing element for sealing the cable and a locking element for locking the sealing element. The sealing element has a through hole extending axially, and the through hole communicates with a through hole at the end of the main body device. Both the sealing element and the locking element are detachably connected to the end of the main body device.

[0013] Preferably, the seal is provided with anti-slip teeth to prevent slippage when the seal is locked.

[0014] Preferably, the sealing member includes a first part for being fitted into the inner periphery of the end of the main body device and a second part for being connected to the first part. The locking member is sleeved on the second part and the outer periphery of the end of the main body device. The outer periphery of the first part is provided with the anti-slip teeth. The outer periphery of the end of the main body device is provided with external threads. The inner periphery of the locking member is provided with internal threads that cooperate with the external threads.

[0015] When using the cable repeater assembly provided by this invention, firstly, place the terminal block inside part of the terminal sleeve, i.e., the terminal sleeve is in an axially split state at this time to facilitate wiring operations at both ends of the terminal block. Then, remove the insulation layer from both cables according to the specified requirements. Next, pass one cable through the through hole at one end of the main unit and crimp the wire portion of the cable to one end of the terminal block. After that, crimp the wire portion of the other cable to the other end of the terminal block. After the crimping wiring operation is completed, close the other part of the terminal sleeve to complete the terminal sleeve assembly, which can better secure the terminal block.

[0016] In addition, since the sheath is used to fix and protect the terminals and is made of insulating material, the sheath can effectively avoid the risk of arcing between the terminal sheath and the main device under high voltage and high current conditions due to gaps at the splicing position.

[0017] Finally, the assembled sheath device is inserted axially into the main body device, and the cables at both ends are sealed and locked by the sealing devices at both ends of the main body device to complete the assembly process of the cable repeater assembly.

[0018] Because the terminal sheath is detachable, all components of this device, except for the wiring terminals, can be reused. This helps to extend the device's lifespan and reduce its operating costs. Furthermore, the wiring operation of this device is simple, quick, safe, and reliable, making it suitable for widespread use.

[0019] In summary, the cable repeater assembly provided by this invention can quickly complete the wiring work and effectively improve the utilization rate of parts and reduce the operating cost of the device. Attached Figure Description

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] The core of this invention is to provide a cable repeater assembly that can quickly complete wiring work and effectively improve the reusability of parts and reduce the operating cost of the device.

[0039] Please refer to Figures 1 to 14 .

[0040] The cable repeater assembly provided in this specific embodiment includes: a terminal block 1, an insulating sheath device for fixing and protecting the terminal block 1, and a main body device 2 for fixing and protecting the sheath device. The sheath device includes a terminal sleeve 3 that is detachable and splicable along the axial direction for fixing the terminal block 1. The terminal block 1 is disposed inside the sheath device, and the sheath device is disposed inside the main body device 2. Both the sheath device and the main body device 2 have through holes at both axial ends for allowing the cable to pass through and contact the terminal block 1. The main body device 2 has sealing devices at both axial ends for sealing and locking the cable.

[0041] It should be noted that the two ends of terminal 1 are used to connect to wires of different cables. In order to prevent leakage during the operation of the cable repeater assembly, the sheath device needs to be made of insulating material. The insulating material can be selected in actual use.

[0042] It should also be noted that the terminal sleeve 3 is used to fix the terminal 1. In order to better fix the terminal 1, the terminal sleeve 3 can be set as a device whose internal cavity structure matches the shape and size of the terminal 1. This can better fix the terminal 1.

[0043] Furthermore, the terminal sleeve 3 can be disassembled and spliced ​​along the axial direction, which facilitates wiring operations at both ends of the terminal 1. After the wiring operations are completed, the terminal sleeve 3 can be assembled into a whole. By setting the terminal sleeve 3 as a splicing device, the service life and utilization rate of each component of the cable repeater assembly can be improved. If the terminal 1 is damaged, it can be replaced with a new terminal 1 simply by disassembly, allowing it to continue to be used with other components, greatly reducing operating costs and maintenance costs.

[0044] It should also be noted that the main body device 2 primarily serves as a housing to protect all internal components. Because the main body device 2 can fix and protect the sheath device, the sheath device should be sized and fitted to the internal cavity of the main body device 2 for better fixation. Preferably, the main body device 2 can be made of metal to prevent deformation.

[0045] In practical applications, the structure, shape, size, material, and position of the terminal block 1, sheath device, and main body device 2 can be determined according to the actual situation and needs.

[0046] When using the cable repeater assembly provided by this invention, firstly, place the terminal 1 inside a portion of the terminal sleeve 3, i.e., the terminal sleeve 3 is in an axially split state at this time, to facilitate wiring operations at both ends of the terminal 1. Then, remove the insulation layer from both cables according to the specified requirements. Next, pass one cable through the through-hole at one end of the main body 2 and crimp the wire portion of this cable to one end of the terminal 1. Then, crimp the wire portion of the other cable to the other end of the terminal 1. After the crimping wiring operation is completed, close the other part of the terminal sleeve 3 to complete the assembly of the terminal sleeve 3, thus better securing the terminal 1.

[0047] In addition, since the sheath device is used to fix and protect the terminal 1, and it is made of insulating material, the sheath device can effectively avoid the risk of arcing between the terminal sheath 3 and the main device 2 under high voltage and high current conditions due to gaps at the splicing position.

[0048] Finally, the assembled sheath device is inserted axially into the main body device 2, and the cables at both ends are sealed and locked by the sealing devices at both ends of the main body device 2 to complete the assembly process of the cable repeater assembly.

[0049] Because the terminal sleeve 3 is a detachable device, all components of this device, except for the wiring terminal 1, can be reused. This helps to extend the service life of the device and reduce its operating costs. Furthermore, the wiring operation of this device is simple, quick, safe, and reliable, making it suitable for widespread use.

[0050] In summary, the cable repeater assembly provided by this invention can quickly complete the wiring work and effectively improve the utilization rate of parts and reduce the operating cost of the device.

[0051] Based on the above-mentioned cable repeater assembly, preferably, the terminal sleeve 3 has a protrusion in the middle for axially fixing the wiring terminal 1, and the protrusion matches the shape and size of the wiring terminal 1.

[0052] It should be noted that since the terminal 1 generally has a protrusion in the middle, the terminal sleeve 3 also has a protrusion in the middle that matches the shape and size of the terminal 1. This is for better axial fixation and protection of the terminal 1. Therefore, the terminal sleeve 3 can be determined according to the shape and size of the terminal 1, so that the terminal sleeve 3 is set as a device whose internal cavity structure matches the shape and size of the terminal 1.

[0053] In practical applications, the shape, size, structure, and material of the terminal sleeve 3 can be determined according to the actual situation and needs.

[0054] Preferably, both ends of the terminal sheath 3 are provided with bosses for axially fixing the cable.

[0055] This is because both ends of terminal 1 need to be connected to the cable with its insulation stripped, meaning that part of the cable's insulation needs to be stripped to expose the wires for connection to terminal 1. After the cable's insulation is stripped, a boss will be formed. In order for the terminal sleeve 3 to effectively restrict the axial movement of the cable, a boss that matches the shape and size of the cable after the insulation has been stripped can be provided at the end of the terminal sleeve 3.

[0056] If the cable uses two layers of insulation, after stripping the first and second layers, two bosses will be formed. Therefore, two bosses matching the shape and size of this structure can also be provided at both ends of the terminal sheath 3, thereby effectively restricting the axial movement of the cable and wire. Of course, if the cable uses one layer of insulation, only one boss will be formed after stripping the insulation. In this case, a boss matching the shape and size of this structure can be provided at both ends of the terminal sheath 3.

[0057] Therefore, in practical applications, the structure, size, shape, position, and number of the bosses at both ends of the terminal sheath 3 can be determined according to the actual situation and needs.

[0058] Based on the above-mentioned cable repeater assembly, preferably, the sheath device includes an insulating sleeve 4 for fixing and protecting the terminal sheath 3, the terminal sheath 3 is disposed inside the insulating sleeve 4, and the insulating sleeve 4 is disposed inside the main body device 2.

[0059] It should be noted that the terminal sleeve 3 can be disassembled and spliced ​​axially, meaning that the terminal sleeve 3 is assembled from two parts. Due to some uncontrollable factors, there may be a gap at the splicing and covering point. However, under high voltage and high current conditions, this gap may pose a risk of arcing with the main device 2. To avoid this arcing phenomenon, an insulating sleeve 4 can be provided on the outside of the terminal sleeve 3 to provide secondary insulation protection for the terminal sleeve 3 and the terminal 1, thereby effectively improving the safety of this device.

[0060] In practical applications, the shape, size, structure, and material of the insulating sleeve 4 can be determined according to the actual situation and needs.

[0061] Based on the above-mentioned cable repeater assembly, preferably, the main body device 2 is provided with a foolproof stop to ensure the uniqueness of the assembly direction, and the sheath device is provided with an installation position to cooperate with the foolproof stop to form a unique assembly direction.

[0062] It should be noted that the foolproof stop is designed to prevent operators from assembling components incorrectly during the assembly or maintenance of the cable repeater assembly. Therefore, by setting a foolproof stop on the main body 2 and providing a corresponding mounting position on the sheath device, the uniqueness of the assembly direction can be effectively guaranteed through the cooperation of the two.

[0063] Preferably, a foolproof stop can be provided at one end of the main body device 2, and a mounting position can be provided at the corresponding end of the insulating sleeve 4. The shape and size of the foolproof stop and the mounting position are matched to ensure that the assembly direction is unique.

[0064] In practical applications, the shape, size, structure, and location of the foolproof stop and installation position can be determined according to the actual situation and needs.

[0065] Preferably, the outer side of the main unit 2 is coated with fluorescent paint to facilitate nighttime maintenance operations. By coating the outer side of the main unit 2 with fluorescent paint, which reflects light under weak light conditions at night, operators can easily locate the cable repeater assembly at night, thus facilitating nighttime maintenance operations.

[0066] Based on the above-mentioned cable repeater assembly, preferably, the sealing device includes a sealing element 5 for sealing the cable and a locking element 6 for locking the sealing element 5. The sealing element 5 has a through hole extending through it in the axial direction. The through hole communicates with the through hole at the end of the main body device 2. Both the sealing element 5 and the locking element 6 are detachably connected to the end of the main body device 2.

[0067] Therefore, the cable passes through the main body device 2 axially, and after its wire part is crimped with the terminal 1, it can be sealed by the sealing parts 5 at both ends of the main body device 2, and then locked by the locking parts 6, so as to ensure that the two cables are effectively locked and sealed.

[0068] In practical applications, the shape, structure, size, position, and material of the sealing element 5 and the locking element 6 can be determined according to the actual situation and needs.

[0069] Preferably, the sealing element 5 is provided with anti-slip teeth, so as to prevent the sealing element 5 from slipping when the locking element 6 locks the sealing element 5.

[0070] Based on the above-mentioned cable repeater assembly, preferably, the sealing member 5 includes a first part for being embedded in the inner periphery of the end of the main body device 2 and a second part for being connected to the first part, and the locking member 6 is sleeved on the outer periphery of the second part and the end of the main body device 2. The outer periphery of the first part is provided with anti-slip teeth, the outer periphery of the end of the main body device 2 is provided with external threads, and the inner periphery of the locking member 6 is provided with internal threads that cooperate with the external threads.

[0071] In this embodiment, when assembling the cable repeater assembly, firstly, the terminal block 1 is placed inside a portion of the terminal sleeve 3, i.e., the terminal sleeve 3 is in an axially split state to facilitate wiring operations at both ends of the terminal block 1. Simultaneously, one end of the main body 2 is connected to the sealing member 5, so that the first part is embedded in the inner periphery of the end of the main body 2, and then the locking member 6 is fitted onto the second part and the outer periphery of one end of the main body 2. Next, the insulation layer of both cables is removed according to specified requirements. Then, one of the cables is sequentially passed through the locking member 6, the sealing member 5, and the through hole at one end of the main body 2, and the wire portion of this cable is crimped to one end of the terminal block 1.

[0072] Next, the wire portion of the other cable is crimped to the other end of terminal 1. After the crimping is completed, the other part of the terminal sleeve 3 is covered to ensure the terminal sleeve 3 is fully assembled, which better secures and protects terminal 1. Then, the insulating sleeve 4 is fitted onto the outer periphery of the assembled terminal sleeve 3, and the assembled insulating sleeve 4, terminal sleeve 3, and terminal 1 are axially inserted into the main body 2. Finally, the other end of the main body 2 is connected to the sealing element 5, so that the first part is embedded in the inner periphery of the end of the main body 2, and the locking element 6 is fitted onto the second part and the outer periphery of the other end of the main body 2. The locking element 6 is then tightened, completing the assembly of the cable repeater assembly.

[0073] Preferably, the sealing element 5 can be a sealing ring, and the locking element 6 can be a tightening nut.

[0074] It should also be noted that the first part is located on the inner periphery of the end of the main body device 2, and the outer periphery of the first part is provided with anti-slip teeth, which is to better seal the main body device 2 and also to prevent the sealing ring from slipping when tightening the tightening nut.

[0075] Therefore, except for terminal block 1, all other components of this device can be reused, which can improve the service life of the device and reduce operating costs. Furthermore, the wiring operation of this device is simple, quick, safe, and reliable.

[0076] Furthermore, it should be noted that the first part and the second part mentioned in this application are only distinguished by their different positions. The first part is embedded in the inner periphery of the end of the main body device 2, while the second part abuts against the end of the main body device 2.
