DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0022] Example 1: Please refer to Figure 1-Figure 3 A portable instant-melting cable joint welding device includes a welding structure 2, which includes a welding plate 21 and a welding groove 211 opened at the top of the welding plate 21, and top connecting plates 213 are symmetrically installed at the top of the welding plate 21 and on both sides of the welding groove 211. Cable grooves 212 are penetrated through the middle ends of both sides of the welding plate 21, and a covering plate 22 is installed between the two groups of the top connecting plates 213. An observation groove 221 is penetrated through the middle end of the covering plate 22, and a cartridge heater 222 is penetrated through the middle end of the covering plate 22 and on both sides of the observation groove 221.

[0023] One end of the cartridge heater 222 is electrically connected to a connecting cable 25, which in turn is connected to a temperature controller 1. This controller primarily relies on a temperature sensor (such as a thermocouple or RTD) to monitor the heater surface temperature in real time and compare it with a set target temperature. When the temperature reaches or exceeds the set value, the controller automatically disconnects the power supply and stops heating. When the temperature falls below the set value, the controller reconnects the power supply and restarts the heating process. This automatic adjustment mechanism maintains a constant heating temperature.

[0024] A hand-held rod 26 is installed on one side of the outer surface of the welding groove 211 , and a pushing member 27 is threadedly connected to the outer surface of the welding plate 21 , and the pushing member 27 and the hand-held rod 26 are on the same side, and the cover plate 22 is set close to the side of the hand-held rod 26 .

[0025] The pushing member 27 includes a threaded shaft 271 threadedly connected to the middle end of the welding plate 21, and a silicone rubber column 272 is installed at one end of the threaded shaft 271. The silicone rubber column 272 is located inside the welding groove 211. The silicone rubber column 272 itself is resistant to high temperatures, which facilitates positioning of the welding end of the cable.

[0026] An insulation frame 223 is installed on the outer side of the cartridge heater 222 and on the outer surface of the covering plate 22. An insulation ring 224 is embedded in the middle end of the covering plate 22 and on the outer side of the cartridge heater 222. A threaded hole 225 is opened through the middle end of the covering plate 22 and on the outer side of the insulation frame 223. A clamping member 23 is installed inside the threaded hole 225. The insulation frame 223 and the insulation ring 224 block the heat of the cartridge heater 222 to avoid scalding the operator.

[0027] In this embodiment: the two sets of cables to be welded are respectively placed into the welding groove 211 from the cable grooves 212 on both sides of the welding plate 21, the threaded shaft 271 is rotated so that the silicone rubber column 272 squeezes the welding end of the cable, the temperature controller 1 is turned on, and the cartridge heater 222 is energized. After the cartridge heater 222 heats up, the cable and the weld are welded. The operator can adjust the position of the weld inside the welding groove 211 through the observation groove 221 to avoid poor electrical conduction at the joint. The provided welding plate 21 limits the flow range of the dissolved material. The heat insulation frame 223 provided on the outside of the cartridge heater 222 provides heat insulation protection for the operator's hands to avoid accidental touch and burns when adjusting the weld.

[0028] Example 2: This example is an improvement based on Example 1. For details, please refer to Figure 2-Figure 4A rear pressure plate 227 is installed on the outer side of the bottom end of the covering plate 22, and built-in shafts 226 are installed on both sides of the bottom of the covering plate 22. A movable groove 214 is opened on the side close to the two groups of top connecting plates 213, and a torsion spring 215 is installed inside the movable groove 214. The built-in shaft 226 is adapted to the movable groove 214, and one end of the torsion spring 215 is installed at one end of the built-in shaft 226.

[0029] The clamping member 23 includes a threaded rod 236 threadedly connected to the inside of the threaded hole 225, one end of the threaded rod 236 is installed with an inner rotating circular plate 235, the other end of the threaded rod 236 is installed with a hand-holding ring 24, an outer side of the inner rotating circular plate 235 is provided with an external cylinder 233, one end of the external cylinder 233 is provided with a T-shaped rotating groove 234, the inner rotating circular plate 235 is movably installed inside the T-shaped rotating groove 234, one end of the external cylinder 233 is installed with a bent insertion frame 231, the inner wall of the bent insertion frame 231 is installed with an anti-slip strip 232, and the anti-slip strip 232 is in contact with the fusion cable to prevent the cable from falling off.

[0030] In this embodiment, after the weld is cooled and solidified, the hand-held lever 26 is held and the rear pressure plate 227 can be pressed downward with a finger. The built-in shaft 226 rotates inside the movable groove 214, and then drives one end of the torsion spring 215 to rotate. The torsion spring 215 itself is deformed, and the cover plate 22 rotates from the top of the welding plate 21 from the horizontal direction to the vertical direction, and the welding structure 2 is moved downward. The cable welding part is moved out of the welding groove 211. When the next group of cables is placed, the cables are moved into the welding groove 211 through the cable groove 212, and the cover plate 22 is released. After the pressure is applied, the torsion spring 215 uses its own resilience to rotate the covering plate 22 to the top of the welding plate 21, and the bent frame 231 constrains the cable from the top. The anti-slip strip 232 is in contact with the cable to prevent the cable from sliding. When the cable is thin, the hand-held ring 24 can be held to rotate the threaded rod 236. When the threaded rod 236 rotates, it can push the bent frame 231 to move toward the top of the cable. The bent frame 231 is constrained by the cable and maintains its downward angle. After the bent frame 231 moves downward, the bent frame 231 and the welding plate 21 clamp the cable to prevent the cable from detaching.
