Description

Technical Field

[0001] This application relates to the field of fusion welding technology, and in particular to a cable fusion splicing device. Background Technology

[0002] With the rapid pace of global urbanization and the increasing value of urban space, power cables are playing an increasingly important role in urban power transmission. As the coverage of medium-voltage cables expands, they are gradually replacing urban overhead lines. However, due to complex construction site conditions, limitations in cable production length, and potential operational failures, cable splicing has become a critical issue that must be addressed.

[0003] To address the issue of splicing broken cables, cable fusion splicing devices are typically used to melt and weld the broken cable. However, common cable fusion splicing devices are prone to introducing impurities during the fusion process, causing secondary contamination and affecting the quality of the weld. Summary of the Invention

[0004] Therefore, it is necessary to provide a cable splicing device to ensure the quality of splicing.

[0005] A cable fusion splicing device is used to fusion splice a first cable joint and a second cable joint, the cable fusion splicing device comprising:

[0006] A first positioning component is used to position the first cable connector;

[0007] The second positioning component is used to position the second cable connector. The first positioning component and the second positioning component are arranged opposite to each other and can move closer or further apart.

[0008] The welding assembly includes a welding cavity, a first opening, and a second opening. The welding cavity communicates with the first opening and the second opening. The first opening is used for inserting a first cable connector into the welding cavity, and the second opening is used for inserting a second cable connector into the welding cavity. The cleaning assembly is connected to the welding assembly and is used to clean the first cable connector and the second cable connector inserted into the welding cavity before welding. The welding assembly is used to weld the first cable connector and the second cable connector located in the welding cavity.

[0009] In one embodiment, the cleaning assembly includes a cleaning air source and a connecting pipe. The cleaning air source has a first air outlet, and the welding assembly has a first air inlet connected to the welding cavity. The connecting pipe has a second air inlet and a second air outlet, with the first air outlet connected to the second air inlet and the first air inlet connected to the second air outlet. Gas in the cleaning air source can enter the welding cavity through the connecting pipe to purge the first cable connector and the second cable connector within the welding cavity.

[0010] In one embodiment, the cleaning air source includes a cleaning pipe connected to the first positioning component and the second positioning component. When the first positioning component and the second positioning component approach each other, at least a portion of the cleaning pipe can be compressed to allow gas in the cleaning pipe to enter the welding chamber to purge the first cable connector and the second cable connector within the welding chamber.

[0011] In one embodiment, the cleaning tube includes a fixed tube, a first corrugated tube, and a second corrugated tube that are connected to each other. The fixed tube is disposed between the first positioning component and the second positioning component. The first air outlet is disposed in the fixed tube. The first corrugated tube is disposed between the fixed tube and the first positioning component. The second corrugated tube is disposed between the fixed tube and the second positioning component. The first corrugated tube and the second corrugated tube are capable of extending and retracting along the movement direction of the first positioning component and the second positioning component.

[0012] In one embodiment, the connecting pipe is further provided with a third air inlet, which is connected to the second air inlet and the second air outlet;

[0013] The second air outlet is provided with a first one-way valve, which is used to control the opening and closing between the first air inlet and the second air outlet; and / or, the third air inlet is provided with a second one-way valve, which is used to control the opening and closing between the third air inlet and the outside air.

[0014] In one embodiment, the welding assembly is provided with an exhaust pipe, the exhaust pipe is provided with a fourth air inlet and a fourth air outlet, the fourth air inlet is connected to the second air outlet, and the fourth air outlet is connected to the first air inlet;

[0015] The exhaust pipe is also provided with a first exhaust port, and the cable splicing device further includes a filter module, which is disposed in the exhaust pipe and is used to filter the gas discharged from the first exhaust port.

[0016] In one embodiment, the filter module includes a housing, a filter element, and a swirl element. The housing is connected to the exhaust pipe, and the filter element and the swirl element are both disposed within the housing. The housing has a second exhaust port, which is located downstream of the filter element along the exhaust direction. The first exhaust port communicates with the second exhaust port. The filter module also includes a sealing element, which is detachably disposed at the second exhaust port.

[0017] In one embodiment, the cable splicing device further includes a self-cleaning module disposed on the filter module, the self-cleaning module being used to clean the filter module; the housing is detachably disposed on the exhaust pipe, and an elastic element is provided between the exhaust pipe and the housing, the elastic element being able to push the housing to move away from the exhaust pipe when the housing is detached from the exhaust pipe, so as to separate the housing from the exhaust pipe.

[0018] In one embodiment, the welding assembly includes a welding cylinder and an induction coil. The welding cavity, the first opening, and the second opening are all disposed on the welding cylinder. The first opening faces the first positioning component, the second opening faces the second positioning component, and the induction coil is wound around the outer peripheral surface of the welding cylinder.

[0019] In one embodiment, the welding cylinder includes a first main body and a second main body that are separately disposed. A first side of the first main body is movably connected to a first side of the second main body, and a second side of the first main body is detachably connected to a second side of the second main body, so that the welding cylinder has an open state and a closed state. In the open state, the second side of the first main body is separated from the second side of the second main body, and the first end of the induction coil along its circumference is separated from the second end. In the closed state, the second side of the first main body is in contact with the second side of the second main body, and the first end of the induction coil along its circumference is in contact with the second end.

[0020] In the aforementioned cable splicing device, during splicing, a first positioning component positions the first cable connector, and a second positioning component positions the second cable connector. Then, both the first and second positioning components move towards the splicing component, causing the first cable connector to be inserted into the splicing cavity through the first opening, and the second cable connector to be inserted into the splicing cavity through the second opening. After the first and second cable connectors are inserted into the splicing cavity through the first and second openings, a cleaning component cleans the first and second cable connectors to remove any impurities that may have been introduced during the splicing process, thereby ensuring the strength and reliability of the splice and improving the splicing quality.

Detailed Implementation

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] See Figure 1 One embodiment of this application provides a cable fusion splicing device for fusion splicing a first cable joint and a second cable joint.

[0034] It should be noted that the diameter of the first cable connector can be the same as or different from the diameter of the second cable connector, depending on the requirements.

[0035] See Figure 1 and Figure 2The cable splicing device includes a base 10, a first positioning component 20, a second positioning component 30, and a splicing component 40. The first positioning component 20 and the second positioning component 30 are movably disposed on the base 10, opposite to each other. The first positioning component 20 is used to position a first cable connector, and the second positioning component 30 is used to position a second cable connector. The splicing component 40 is disposed between the first positioning component 20 and the second positioning component 30. The splicing component 40 has a splicing cavity 411, a first opening 413, and a second opening 414. The splicing cavity 411 communicates with the first opening 413 and the second opening 414. The first opening 413 is used for inserting the first cable connector into the splicing cavity 411, and the second opening 414 is used for inserting the second cable connector into the splicing cavity 411. The splicing component 40 is used to splice the first cable connector and the second cable connector.

[0036] During welding, the first positioning component 20 positions the first cable connector, and the second positioning component 30 positions the second cable connector. Then, both the first positioning component 20 and the second positioning component 30 move towards the welding assembly 40, causing the first cable connector to be inserted into the welding cavity 411 through the first opening 413, and the second cable connector to be inserted into the welding cavity 411 through the second opening 414. Finally, the welding assembly 40 welds the first and second cable connectors together.

[0037] Furthermore, the base 10 is also provided with a slide rail. The slide rail extends along the moving direction of the first positioning component 20 and the second positioning component 30, and the first positioning component 20 and the second positioning component 30 are mounted on the slide rail. Under the action of the slide rail, the movement of the first positioning component 20 and the second positioning component 30 is guided, thereby improving the stability of the movement of the first positioning component 20 and the second positioning component 30.

[0038] In one embodiment, see Figure 1 The cable splicing device also includes a cleaning component 50. The cleaning component 50 is connected to the splicing component 40 and is used to clean the first cable connector and the second cable connector inserted into the splicing cavity 411. After the first cable connector is inserted into the splicing cavity 411 through the first opening 413 and the second cable connector is inserted into the splicing cavity 411 through the second opening 414, the cleaning component 50 cleans the first and second cable connectors to remove any impurities that may be introduced during the splicing process, thereby ensuring the strength and reliability of the splice and improving the splicing quality.

[0039] In one embodiment, see Figure 1 The cleaning component 50 includes a cleaning air source 51 and a connecting pipe 52. The cleaning air source 51 is connected to the welding cavity 411 through the connecting pipe 52.

[0040] See Figure 4 The welding assembly 40 is provided with a first air inlet 412, and the clean air source 51 is provided with a first air outlet 51111.

[0041] See Figure 4 , Figure 5 and Figure 6 The connecting pipe 52 is provided with a second air inlet 521 and a second air outlet 522. The first air outlet 51111 is connected to the second air inlet 521, and the first air inlet 412 is connected to the second air outlet 522. In this way, the gas in the clean air source 51 enters the welding chamber 411 in sequence through the first air outlet 51111, the second air inlet 521, the second air outlet 522 and the first air inlet 412.

[0042] In one embodiment, see Figure 1 and Figure 2 The cleaning air source 51 includes a cleaning pipe 511. The cleaning pipe 511 is connected to the first positioning component 20 and the second positioning component 30. When the first positioning component 20 and the second positioning component 30 approach each other, at least a portion of the cleaning pipe 511 can be compressed so that the gas in the cleaning pipe 511 enters the welding chamber 411 to purge the first cable joint and the second cable joint in the welding chamber 411.

[0043] During welding, the first positioning component 20 and the second positioning component 30 move towards each other, compressing the cleaning tube 511 and forcing the gas inside the cleaning tube 511 to enter the welding chamber 411 through the first air outlet 51111, the second air inlet 521, the second air outlet 522, and the first air inlet 412. When the first cable connector and the second cable connector are inserted into the welding chamber 411, the space inside the welding chamber 411 narrows, and the air pressure further increases. The gas rushes from the narrowed space to the first opening 413 and the second opening 414, forming a high-pressure washing flow. The high-pressure washing flow can purge the first cable connector and the second cable connector to clean them with airflow and remove impurities from the slits until the first cable connector and the second cable connector respectively close the first opening 413 and the second opening 414. Then, the welding component 40 is activated to weld the first cable connector and the second cable connector.

[0044] In one embodiment, see Figure 1 , Figure 2 and Figure 4The cleaning tube 511 includes a fixed tube 5111, a first corrugated tube 5112, and a second corrugated tube 5113. The fixed tube 5111 is located between the first positioning component 20 and the second positioning component 30, and is correspondingly arranged with the welding component 40. A first vent 51111 is located on the fixed tube 5111. The first corrugated tube 5112 is located between the fixed tube 5111 and the first positioning component 20 and communicates with the fixed tube 5111. The second corrugated tube 5113 is located between the fixed tube 5111 and the second positioning component 30 and communicates with the fixed tube 5111.

[0045] During welding, when the first corrugated tube 5112 and the second corrugated tube 5113 are in their initial state, the first positioning component 20 positions the first cable joint, and the second positioning component 30 positions the second cable joint. Then, the first positioning component 20 moves towards the welding component 40, compressing the first corrugated tube 5112, causing the gas inside the first corrugated tube 5112 to be discharged into the welding chamber 411. At the same time, the second positioning component 30 moves towards the welding component 40, compressing the second corrugated tube 5113, causing the gas inside the second corrugated tube 5113 to be discharged into the welding chamber 411, thereby purging the first and second cable joints to remove impurities from them. In this way, the compressible first bellows 5112 and the second bellows 5113 are integrated between the first positioning component 20 and the second positioning component 30. The movement of the first positioning component 20 and the second positioning component 30 is used to drive the gas into the welding chamber 411, thereby completing the active purging and cleaning before the first cable joint and the second cable joint are welded. The whole process does not require additional driving.

[0046] In one embodiment, see Figure 4 and Figure 6 The connecting pipe 52 is also provided with a third air inlet 523. The third air inlet 523 is connected to the second air inlet 521 and the second air outlet 522.

[0047] In an exemplary embodiment, the second air outlet 522 and the third air inlet 523 are respectively located at both ends of the length direction of the connecting pipe 52, and the second air inlet 521 is located between the second air outlet 522 and the third air inlet 523 and is located close to the third air inlet 523.

[0048] Further, see Figure 4 , Figure 5 and Figure 6 The cable splicing device also includes a first one-way valve 60 and a second one-way valve 61. The first one-way valve 60 is located at the second air outlet 522 and is used to control the opening and closing between the first air inlet 412 and the second air outlet 522; the second one-way valve 61 is located at the third air inlet 523 and is used to control the opening and closing between the third air inlet 523 and the outside air.

[0049] During welding, the first one-way valve 60 is opened and the second one-way valve 61 is closed. The first positioning component 20 and the second positioning component 30 move towards each other, and at least a portion of the cleaning tube 511 is compressed, so that the gas in the cleaning tube 511 is discharged into the welding chamber 411 through the first one-way valve 60.

[0050] After the welding is completed, close the first one-way valve 60 and open the second one-way valve 61. The first positioning component 20 and the second positioning component 30 move away from each other, so that the outside gas enters the cleaning pipe 511 through the second one-way valve 61, ensuring that the first bellows 5112 and the second bellows 5113 can return to their initial state.

[0051] In one embodiment, see Figure 4 and Figure 5 The welding assembly 40 is provided with an exhaust pipe 415. The exhaust pipe 415 is provided with a fourth air inlet 4151 and a fourth air outlet 4152. The fourth air inlet 4151 is connected to the second air outlet 522, and the fourth air outlet 4152 is connected to the first air inlet 412. It can be understood that the connecting pipe 52 is connected to the welding cavity 411 through the exhaust pipe 415.

[0052] Furthermore, the exhaust pipe 415 is also provided with a first exhaust port 4153. The cable splicing device also includes a filter module 70, which is located in the exhaust pipe 415 and is used to filter the gas discharged from the first exhaust port 4153. During splicing, the gas generated by the splicing of the first cable joint and the second cable joint is discharged after passing through the filter module 70. The filter module 70 can filter the gas discharged through the first exhaust port 4153, so that the gas generated by splicing is less likely to pollute the environment, and will not affect the gas in the cleaning pipe 511.

[0053] In one embodiment, see Figure 5 and Figure 8 The filter module 70 includes a housing 71, a filter element 72, and a cyclone separator 73. The housing 71 is connected to the exhaust pipe 415, and both the filter element 72 and the cyclone separator 73 are disposed within the housing 71. During welding, the filter element 72 filters the gas generated during welding, while the cyclone separator 73 rotates within the housing 71 to remove clogging substances from the housing 71, preventing the filter element 72 from becoming clogged and extending the effective filtration time of the filter element 72.

[0054] In an exemplary embodiment, see Figure 5The housing 71 is fitted onto the exhaust pipe 415, and a sealing ring is provided between the housing 71 and the exhaust pipe 415. Two swirling elements 73 are provided; one swirling element 73 is located on the side of the filter element 72 near the first exhaust port 4153, and the other swirling element 73 is located on the side of the filter element 72 away from the first exhaust port 4153. It can be understood that the two swirling elements 73 are respectively located on opposite sides of the filter element 72 along the exhaust direction. During welding, the swirling directions of the two swirling elements 73 are opposite, causing the swirling flow formed by the first swirling element 73 to undergo flow-induced shearing action with the swirling flow formed by the second swirling element 73 during airflow, thereby stripping away clogging substances inside the housing 71, preventing the filter element 72 from clogging, extending the effective filtration time of the filter element 72, and ensuring that impurities can quickly detach from the filter element 72, improving cleaning efficiency.

[0055] In one embodiment, see Figure 5 The housing 71 is provided with a second vent 711. The second vent 711 is located downstream of the filter element 72 along the venting direction, and the first vent 4153 communicates with the second vent 711.

[0056] Further, see Figure 5 The filter module 70 also includes a sealing element 74. The sealing element 74 is detachably disposed in the second vent 711. When the first cable connector and the second cable connector are purged and cleaned, the sealing element 74 is disposed in the second vent 711 to ensure that gas can directly enter the welding chamber 411. When the first cable connector and the second cable connector are welded, the sealing element 74 is removed from the second vent 711, so that the gas generated during welding can be discharged through the first vent 4153 and the second vent 711, reducing the occurrence of porosity defects at the welding point of the first cable connector and the second cable connector, and ensuring the welding quality.

[0057] See Figure 2 The filter module 70 also includes an actuator 75. The actuator 75 is located in the housing 71 and is connected to the sealing member 74. The actuator 75 is used to seal the sealing member 74 or open the second vent 711. Optionally, the actuator 75 is an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0058] In one embodiment, see Figure 5 The cable splicing device also includes a self-cleaning module 80. The self-cleaning module 80 is located within the filter module 70 and is used to clean the filter module 70. In this way, the self-cleaning module 80 can clean the filter module 70, ensuring the filtration effect of the filter module 70.

[0059] Optionally, see Figure 5 The self-cleaning module 80 includes a vibration module 81. The vibration module 81 is located in the filter module 70.

[0060] In an exemplary embodiment, the vibration module 81 is disposed outside the housing 71. After welding is completed, the vibration module 81 is activated, and the vibration module 81 vibrates the filter module 70 to clean the filter element 72. During the cleaning process of the filter element 72, airflow can be used to blow out the cleaned dust.

[0061] In one embodiment, the housing 71 is detachably disposed on the exhaust pipe 415. Specifically, the housing 71 is provided with a first locking hole, the exhaust pipe 415 is provided with a second locking hole, and a first locking element is provided in both the first and second locking holes. The first locking element is a screw, bolt, etc., and is not limited thereto.

[0062] Further, see Figure 5 The self-cleaning module 80 also includes an elastic element 82. The elastic element 82 is connected to the exhaust pipe 415 and the housing 71. When the housing 71 is disassembled from the exhaust pipe 415, the elastic element 82 can push the housing 71 to move away from the exhaust pipe 415, so that the housing 71 is separated from the exhaust pipe 415.

[0063] It should be noted that, if the filter module 70 needs to be cleaned, the first positioning component 20 and the second positioning component 30 should first be moved away from each other to their initial positions. Then, the first positioning component 20 and the second positioning component 30 should be moved closer to each other, so that the cleaning tube 511 is compressed, causing the gas in the cleaning tube 511 to enter the exhaust tube 415. Then, part of the gas enters the welding chamber 411, and the other part of the gas enters the filter module 70 through the first exhaust port 4153, so as to blow the impurities on the filter element 72 out of the housing 71 through the second exhaust port 711, without contaminating the welding cylinder 41.

[0064] In an exemplary embodiment, see Figure 5 The elastic element 82 is a spring, which is sleeved on the outside of the exhaust pipe 415. When the housing 71 is fixed to the exhaust pipe 415, the spring is in a compressed state; when the housing 71 is disassembled from the exhaust pipe 415, the elastic element 82 switches from the compressed state to a freely extended state, so as to push the housing 71 to move away from the exhaust pipe 415, thereby separating the housing 71 from the exhaust pipe 415.

[0065] Of course, in other embodiments, a vacuum cleaner may also be provided outside the housing 71.

[0066] In one embodiment, see Figure 1 , Figure 2 and Figure 4The welding assembly 40 includes a welding cylinder 41 and an induction coil 42. A welding cavity 411, a first opening 413, a second opening 414, and a first air inlet 412 are all located on the welding cylinder 41, with the first opening 413 and the second opening 414 located on opposite end faces of the welding cylinder 41. The induction coil 42 is wound around the outer circumference of the welding cylinder 41 and is electrically connected to an external power source. During welding, the induction coil 42 is energized, causing the first cable connector and the second cable connector to undergo high-temperature welding. After welding is completed, the induction coil 42 is de-energized.

[0067] Optionally, the welding cylinder 41 is made of ceramic material. Of course, in other embodiments, the welding cylinder 41 may also be made of other materials, and is not limited thereto.

[0068] Further, see Figure 3 and Figure 4 The welding cylinder 41 includes a first body 416 and a second body 417, which are separately disposed. A first side of the first body 416 is movably connected to a first side of the second body 417. In an exemplary embodiment, the first side of the first body 416 and the first side of the second body 417 are hinged. A second side of the first body 416 and the second side of the second body 417 are detachably connected, allowing the second sides of the first body 416 and the second body 417 to contact or separate. In an exemplary embodiment, a third locking hole is provided on the second side of the first body 416, and a fourth locking hole is provided on the second side of the second body 417. A second locking member is provided within the third and fourth locking holes, and the second locking member detachably connects the second side of the first body 416 and the second side of the second body 417.

[0069] In an exemplary embodiment, the first body 416 is above the second body 417, and the second body 417 is below the first body 416, that is, the first body 416 and the second body 417 are distributed vertically.

[0070] During welding, the second side of the first body 416 and the second side of the second body 417 are connected by a second locking member. After welding is completed, the second locking member is removed, and the first body 416 is flipped over, separating the second side of the first body 416 from the second side of the second body 417. This facilitates the removal of the welded first and second cable connectors from between the second sides of the first body 416 and the second body 417. Thus, using a separate welding cylinder 41 avoids damage to the welding cylinder 41, extends its service life, and allows for reuse, which helps reduce costs.

[0071] Furthermore, the base 10 is provided with a support frame for supporting the welding cylinder 41. Specifically, the second main body 417 is mounted on the support frame. In this way, the support frame can support the welding cylinder 41. The support form of the support frame can be reasonably arranged so as not to affect the arrangement of the cleaning components 50.

[0072] In one embodiment, the induction coil 42 has a first end and a second end along the circumference of the welding cylinder 41. It is understood that after the induction coil 42 is wound around the outer circumference of the welding cylinder 41, the portions of the induction coil 42 corresponding to the second side of the first body 416 and the second side of the second body 417 are cut off, so that the induction coil 42 has a first end and a second end along the circumference of the welding cylinder 41, wherein the first end of the induction coil 42 is correspondingly disposed to the second side of the first body 416, and the second end of the induction coil 42 is correspondingly disposed to the second side of the second body 417.

[0073] When the welding cylinder 41 is in the open state, the second side of the first body 416 is separated from the second side of the second body 417, and the first end of the induction coil 42 is separated from the second end. When the welding cylinder 41 is in the closed state, the second side of the first body 416 is in contact with the second side of the second body 417, and the first end of the induction coil 42 is in contact with the second end. In this way, the induction coil 42 can adapt to the separate welding cylinder 41.

[0074] Further, see Figure 4 and Figure 7 At least one of the first end and the second end of the induction coil 42 is provided with a contact 421. When the second side of the first body 416 contacts the second side of the second body 417, the first end of the induction coil 42 is electrically connected to the second end of the induction coil 42 through the contact 421, ensuring the conductivity of the induction coil 42.

[0075] In one embodiment, the connecting pipe 52 is a flexible tube. After the welding is completed, the first body 416 is flipped relative to the second body 417. Since the connecting pipe 52 is a flexible structure, the connecting pipe 52 will not affect the flipping of the first body 416.

[0076] In one embodiment, the first positioning component 20 is a clamp for holding the first cable connector.

[0077] Further, see Figure 1 The first positioning component 20 includes a first clamping body 21 and a second clamping body 22. The first clamping body 21 is provided with a first clamping groove, and the second clamping body 22 is provided with a second clamping groove; when the first clamping body 21 and the second clamping body 22 are connected, the first clamping groove and the second clamping groove surround to form a first clamping hole 211.

[0078] Optionally, the first side of the first clamping body 21 is hinged to the first side of the second clamping body 22, and the second side of the first clamping body 21 and the second side of the second clamping body 22 are detachably connected by a fastener. The fastener can be a screw, bolt, or similar object, and is not limited thereto.

[0079] Optionally, the first side of the first clamping body 21 and the first side of the second clamping body 22 are detachably connected by a fastener, and the second side of the first clamping body 21 and the second side of the second clamping body 22 are also detachably connected by a fastener. The fastener can be a screw, bolt, or similar component, and is not limited to this.

[0080] In one embodiment, the second positioning component 30 is a clamp for holding the second cable connector.

[0081] Further, see Figure 1 The second positioning component 30 includes a third clamping body 31 and a fourth clamping body 32. The third clamping body 31 is provided with a third clamping groove, and the fourth clamping body 32 is provided with a fourth clamping groove; when the third clamping body 31 and the fourth clamping body 32 are connected, the third clamping groove and the fourth clamping groove surround to form a second clamping hole 311.

[0082] Optionally, the first side of the third clamping body 31 is hinged to the first side of the fourth clamping body 32, and the second side of the third clamping body 31 is detachably connected to the second side of the fourth clamping body 32 by means of a fastener. The fastener may be a screw, bolt, or similar material, and is not limited thereto.

[0083] Optionally, the first side of the third clamping body 31 and the first side of the fourth clamping body 32 are detachably connected by a fastener, and the second side of the third clamping body 31 and the second side of the fourth clamping body 32 are detachably connected by a fastener. The fastener can be a screw, bolt, or other similar component, and is not limited to this.

[0084] In one embodiment, see Figure 3 The first positioning component 20, the second positioning component 30, and the welding component 40 are coaxially arranged. It can be understood that the center of the first clamping hole 211 and the center of the second clamping hole 311 are located on the central axis of the welding cavity 411.

[0085] In one embodiment, see Figure 1 and Figure 2 The cable splicing device also includes a drive assembly 90. The drive assembly 90 is connected to the first positioning assembly 20 and the second positioning assembly 30, and is used to drive the first positioning assembly 20 and the second positioning assembly 30 to move closer or further apart. Thus, under the drive of the drive assembly 90, the first positioning assembly 20 and the second positioning assembly 30 can move closer or further apart.

[0086] Further, see Figure 1 and Figure 2 The drive assembly 90 includes a motor and a ball screw 93. The ball screw 93 is rotatably mounted on the base 10, and the motor is driven by the ball screw 93. The ball screw 93 is a bidirectional ball screw. The first positioning assembly 20 is connected to the left-hand thread of the bidirectional ball screw 93, and the second positioning assembly 30 is connected to the right-hand thread of the bidirectional ball screw 93. During operation, the motor starts and drives the ball screw 93 to rotate around its own axis, thereby causing the first positioning assembly 20 and the second positioning assembly 30 to move closer together or separate.

[0087] In one embodiment, see Figure 1 and Figure 3 There are two ball screws 93. One end of each ball screw 93 is connected to the first positioning component 20, and the second end of each ball screw 93 is connected to the second positioning component 30.

[0088] Further, see Figure 1 and Figure 2 The drive assembly 90 also includes a drive pulley 91 and a drive belt 92. There are two drive pulleys 91, one connected to one ball screw 93 and the other connected to the other ball screw 93. The drive belt 92 is wound around the two drive pulleys 91, and the motor is connected to at least one of the first and second drive pulleys 91. Thus, one motor can drive the two ball screws 93 to rotate synchronously.

[0089] Of course, in other embodiments, the transmission belt 92 may also be a transmission chain, and is not limited thereto.

[0090] In an exemplary embodiment, one of the ball screws 93 is provided with a coupling, which is connected to a motor via a reducer. The motor drives the ball screw 93 to rotate, thereby driving the first positioning component 20 and the second positioning component 30.

[0091] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0092] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0093] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0094] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0095] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0096] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0097] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
