Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a welding-free connector. Background Art

[0002] A connector is a device that connects multiple signal or power lines in sequence. Its function is to bridge blocked or isolated circuits within a circuit, allowing current to flow and the circuit to function as intended. Existing connectors require soldering the wires to the conductors within the connector during installation. This is difficult due to space constraints, is time-consuming, and inefficient. Welding is also prone to poor solder joints, making it difficult to manually determine if the soldering is acceptable. This increases the connector's failure rate during subsequent use. Furthermore, in some special situations, soldering machines cannot be used, making connector installation difficult. Summary of the Invention

[0006] Furthermore, the first groove of the first connecting rod is set at a right angle away from the side wall of the insulating rubber core, and the first groove is chamfered close to the side wall of the insulating rubber core. The structure of the first groove is the same as that of the second groove.

[0007] Furthermore, a chamfer is set on one end of the first connecting rod inserted into the first terminal, and a chamfer is set on one end of the second connecting rod inserted into the second terminal.

[0008] Furthermore, the insulating rubber core is provided with a first guide groove and a second guide groove, and a first retaining ring is provided around the insulating rubber core, and the first guide groove and the second guide groove are separated by the first retaining ring. The first guide groove is provided on the outer wall away from one end of the inner tooth of the plug, and the second guide groove is provided on the outer wall close to one end of the inner tooth of the plug. The insulating rubber core is provided with a first positioning groove close to the first guide groove.

[0009] Furthermore, the inner thread of the plug is provided with a guide rail, the position of the guide rail corresponds to the position of the second guide groove, a second retaining ring is provided around the outer wall of the inner thread of the plug, and the end of the insulating rubber core close to the inner thread of the plug is inserted into the inner thread of the plug for sleeve connection.

[0010] Furthermore, the socket shell is used to fix the insulating rubber core, and the socket shell is provided with a guide block and a positioning buckle. The position of the guide block corresponds to the first guide groove, the position of the positioning buckle corresponds to the first positioning groove, and the outer wall of the socket shell is provided with a second positioning groove.

[0011] Furthermore, the plug shell is used to fix the socket shell and the plug inner teeth, the plug shell is provided with a spring buckle, the end of the socket shell close to the second positioning groove is sleeved with the plug shell, and the position of the spring buckle corresponds to the position of the second positioning groove.

[0012] Furthermore, the connector also includes a waterproof tail of a plug, one end of which is sleeved on the plug shell and fixedly connected to the inner thread of the plug through a thread. A first nut is fixed on the waterproof tail of the plug. When the waterproof tail of the plug is connected to the inner thread of the plug, the first nut squeezes the plug shell.

[0013] Furthermore, a waterproof ring surrounding the second cable is provided at one end of the waterproof tail of the plug away from the inner teeth of the plug, and when the second nut is fixedly connected to the waterproof tail of the plug, the first nut and the second nut squeeze the waterproof ring.

[0014] Compared with the prior art, the solder-free connector provided by the present invention has the following advantages:

[0015] 1. The first terminal and the second terminal are respectively provided with corresponding protrusions on the first spring sheet and the second spring sheet, and the first terminal is electrically connected to the first connecting rod by snapping the protrusion on the first spring sheet into the first groove, and the second terminal is electrically connected to the second connecting rod by snapping the protrusion on the second spring sheet into the second groove. At the same time, multiple first terminals are respectively pinched and clamped by corresponding first clamping arms for multiple cores of the first cable, and multiple second terminals are respectively pinched and clamped by corresponding second clamping arms for multiple cores of the second cable, which improves the connection method of using cables to weld the terminal cups separately in traditional connectors, effectively avoids the phenomenon of poor conductivity during the use of the connector due to poor welding, facilitates on-site installation operations, improves installation efficiency, and increases the stability, convenience and speed of connector use.

[0016] 2. Both the first and second spring clips are elastic. When the protrusions of the first and second spring clips are respectively inserted into the first and second grooves, and the elasticity of the first and second spring clips respectively clamps the first and second connecting rods, the first and second connecting rods can be forcibly pulled out of the first and second connecting terminals, respectively, to prevent difficulty in correcting PIN position insertion errors. Furthermore, when multiple first and second connecting terminals are electrically connected to multiple first and second connecting rods and a wiring sequence error occurs, the corresponding first and second connecting rods can be disconnected from the corresponding first and second connecting terminals to disconnect them electrically. After that, the electrical connection sequence of the first and second connecting terminals can be changed to the correct wiring sequence, and the electrical connection sequence of the second and second connecting terminals can be changed to the correct wiring sequence, thereby improving installation efficiency and convenience.

[0017] 3. Multiple first connecting rods extending through the insulating rubber core are connected to the multiple wire cores of the disconnected first cable via multiple first connecting terminals. Multiple second connecting rods extending through the inner teeth of the plug are connected to the multiple wire cores of the disconnected second cable via multiple second connecting terminals. When the socket shell and the plug shell are connected, the multiple first connecting rods and the multiple second connecting rods are electrically connected, respectively, achieving mutual conduction between the disconnected first and second cables. Furthermore, the protrusion of the first spring clip provided on the first connecting terminal snaps into the first groove provided on the first connecting rod, and the protrusion of the second spring clip provided on the second connecting terminal snaps into the second groove provided on the second connecting rod, respectively increasing the frictional connection between the first connecting terminal and the first connecting rod, and the second connecting terminal and the second connecting rod, respectively, ensuring stable connection between the first and second connecting terminals.

[0018] 4. When the receptacle housing is inserted into the plug housing, the multiple first connecting rods extending through the insulating rubber core and the multiple second connecting rods extending through the plug threads are simultaneously electrically connected. Therefore, by connecting or disconnecting the receptacle housing and the plug housing, the multiple first connecting rods and the multiple second connecting rods can switch between open and closed states, thereby switching between open and closed states between the first and second cables. Because the first connecting rods extend through the insulating rubber core within the receptacle housing, and the second connecting rods extend through the plug threads within the plug housing, when the receptacle housing and the plug housing are connected, moisture oxidation of the first and second connecting rods is prevented, which could affect electrical conductivity and shorten the life of the connector.

[0034] See also Figures 1 to 10The present invention provides a solder-free connector 1, which includes a connecting base 2 and a connecting head 3. The connecting base 2 includes a socket shell 24, an insulating rubber core 23, a plurality of first connecting terminals 21 and a plurality of first connecting rods 22. The connecting head 3 includes a plug shell 31, a plug inner tooth 32, a plurality of second connecting terminals 35 and a plurality of second connecting rods 34. A first spring piece 211 with a protrusion is provided at one end of the first connecting terminal 21, and a first wire clamping arm 212 is provided at the other end of the first connecting terminal 21. A second spring piece 351 with a protrusion is provided at one end of the second connecting terminal 35, and a second wire clamping arm 352 is provided at the other end of the second connecting terminal 35. The plurality of first connecting terminals 21 are correspondingly pinched and clamped to hold the plurality of wire cores of the first cable 4 through the first wire clamping arm 212, and the plurality of second connecting terminals 35 are correspondingly pinched and clamped to hold the plurality of wire cores of the second cable 5 through the second wire clamping arm 352. A connecting rod 22 is provided with an annular first groove 221 at one end, and the other end of the first connecting rod 22 is inserted into the insulating rubber core 23 and provided with a plug hole. A second connecting rod 34 is provided with an annular second groove 341 at one end, and the other end of the second connecting rod 34 is inserted into the plug inner tooth 32 and provided with an exposed plug column. Multiple first connecting terminals 21 are inserted into the first grooves 221 of the multiple first connecting rods 22 through corresponding first elastic clips 211, and multiple second connecting terminals 35 are inserted into the second grooves 341 of the multiple second connecting rods 34 through corresponding second elastic clips 351; the socket shell 24 and the plug shell 31 are socketed, the insulating rubber core 23 and the plug inner tooth 32 are socketed, the multiple first connecting rods 22 are socketed through the provided plug holes and the multiple second connecting rods 34 are socketed through the provided plug columns, and the multiple first connecting rods 22 and the multiple second connecting rods 34 are electrically connected respectively.

[0035] It can be understood that the first terminal 21 and the second terminal 35 are respectively provided with corresponding protrusions on the first spring piece 211 and the second spring piece 351, and the first terminal 21 is electrically connected to the first connecting rod 22 by snapping the protrusion on the first spring piece 211 into the first groove 221, and the second terminal 35 is electrically connected to the second connecting rod 34 by snapping the protrusion on the second spring piece 351 into the second groove 341. At the same time, multiple first terminals 21 are respectively pinched and clamped by the corresponding first clamping arms 212 for the multiple cores of the first cable 4, and multiple second terminals 35 are respectively pinched and clamped by the corresponding second clamping arms 352 for the multiple cores of the second cable 5, which improves the connection method of using cables to weld the terminal cups separately in traditional connectors, effectively avoids the phenomenon of poor conductivity during the use of the connector due to poor welding, facilitates on-site installation operations, improves installation efficiency, and increases the stability, convenience and speed of connector use.

[0036] It can be understood that both the first spring clip 211 and the second spring clip 351 are elastic. When the protrusions of the first spring clip 211 and the protrusions of the second spring clip 351 are respectively inserted into the first groove 221 and the second groove 232, and the first connecting rod 22 and the second connecting rod 34 are respectively clamped by the elasticity of the first spring clip 211 and the elasticity of the second spring clip 351, the first connecting rod 22 and the second connecting rod 34 can be forcibly pulled out from the first terminal 21 and the second terminal 35, respectively, to prevent difficulty in correcting PIN position errors. Furthermore, when a plurality of first connecting terminals 21 and a plurality of second connecting terminals 35 are electrically connected to a plurality of first connecting rods 22 and a plurality of second connecting rods 34 respectively and a wiring sequence error occurs, the corresponding first connecting rods 22 and the second connecting rods 34 can be disconnected by respectively pulling out the corresponding first connecting terminals 21 and the second connecting terminals 35 to disconnect them electrically, and then the electrical connection sequence of the first connecting terminals 21 and the first connecting rods 22 can be replaced with the correct wiring sequence, and the electrical connection sequence of the second connecting terminals 35 and the second connecting rods 34 can be replaced with the correct wiring sequence, thereby improving installation efficiency and convenience.

[0037] Preferably, a plurality of first spring clips 211 are symmetrically arranged on the first terminal 21, and a gap is provided between the side walls of the first spring clip 211 and the first terminal 21, and the protrusion of the first spring clip 211 is arranged toward the inner side of the first terminal 21, and the structure of the first terminal 21 is the same as that of the second terminal 35.

[0038] As can be understood, both the first terminal 21 and the second terminal 35 are made of a tubular conductive material. A first spring clip 211 slot for receiving the first spring clip 211 is provided at one end of the first terminal 21, proximate the first spring clip 211. The ends of the first spring clip 211 are fixedly connected to the ends of the first spring clip 211 slot. The two sides of the first spring clip 211 are smaller than the two ends of the first spring clip 211 slot, creating a gap between the two sides of the first spring clip 211 and the first terminal 21. The center of the first spring clip 211 deforms toward the inside of the first terminal 21. Because the first spring clip 211 deforms toward the inside of the first terminal 21, the first terminal 21 is clamped and connected to the first connecting rod 22 by the first spring clip 211 snapping into the first slot 221. Since the structures of the first terminal 21 and the second terminal 35 are identical, the second terminal 35 snaps into the second slot 341 in the same manner, clamping and connecting the second connecting rod 34.

[0039] It can be understood that a protrusion is set on the inner side of the first spring piece 211, and the protrusion of the first spring piece 211 is stuck in the first groove 221, and the protrusion of the second spring piece 351 is stuck in the second groove 341, which increases the friction force between the first terminal 21 and the first connecting rod 22, and the second terminal 35 and the second connecting rod 34, so that the first terminal 21 and the second terminal 35 are stably connected to the first connecting rod 22 and the second connecting rod 34, respectively.

[0040] Preferably, the first groove 221 of the first connecting rod 22 is set at a right angle away from the side wall of the insulating rubber core 23, and the side wall of the first groove 221 close to the insulating rubber core 23 is chamfered. The structure of the first groove 221 is the same as that of the second groove 341.

[0041] It can be understood that the first groove 221 and the second groove 341 are set at a right angle away from the side wall of the insulating rubber core 23. When the first connecting rod 22 and the second connecting rod 34 are respectively pulled out from the first terminal 21 and the second terminal 35, the first spring piece 211 and the second spring piece 351 respectively contact the first groove 221 and the second groove 341 at a high contact position, thereby increasing the pulling force when the first connecting rod 22 and the second connecting rod 34 are respectively pulled out from the first terminal 21 and the second terminal 35, thereby preventing the first connecting rod 22 and the second connecting rod 34 from being separated from the first terminal 21 and the second terminal 35 due to shaking.

[0042] Specifically, when the first connecting rod 22 is provided with two first grooves 221 and the second connecting rod 34 is provided with two second grooves 341, after the first spring piece 211 is inserted into the first first groove 221, it continues to push the first connecting rod 22. Since the first groove 221 is chamfered on the side close to the insulating rubber core 23, the first spring piece 211 can be inserted into the second first groove 221 along the chamfer of the first first groove 221. At the same time, after the second spring piece 351 is inserted into the first second groove 341, it continues to push the second connecting rod 34. Since the second groove 341 is chamfered on the side close to the insulating rubber core 23, the second spring piece 351 can be inserted into the second second groove 341 along the chamfer of the first second groove 341.

[0043] Preferably, the end of the first connecting rod 22 inserted into the first wiring terminal 21 is chamfered, and the end of the second connecting rod 34 inserted into the second wiring terminal 35 is chamfered.

[0044] It can be understood that chamfers are set on one end of the first connecting rod 22 and the second connecting rod 34 corresponding to the ends inserted into the first connecting terminal 21 and the second connecting terminal 35. When the first connecting rod 22 and the second connecting rod 34 are respectively inserted into the first connecting terminal 21 and the second connecting terminal 35, the first spring clip 211 and the second spring clip 351 can be deformed along the chamfers of the first connecting terminal 21 and the chamfers of the second connecting terminal 35, respectively, so that the first spring clip 211 is clamped into the first groove 221 to clamp and connect the first connecting rod 22, and the second spring clip 351 is clamped into the second groove 341 to clamp and connect the second connecting rod 34.

[0045] It is understood that when the insulating rubber core 23 is connected to the plug inner thread 32, the insertion hole of the first connecting rod 22 and the insertion post of the second connecting rod 34 are socketed. Furthermore, the insertion hole of the first connecting rod 22 is elastic. When the second connecting rod 34 is inserted into the first connecting rod 22, the insertion hole of the first connecting rod 22 and the insertion post of the second connecting rod 34 undergo elastic deformation, increasing the friction between the first connecting rod 22 and the second connecting rod 34, thereby improving the conductive stability of the first connecting rod 22 and the second connecting rod 34.

[0046] Preferably, the insulating rubber core 23 is provided with a first guide groove 231 and a second guide groove 232, and a first retaining ring 233 is provided around the insulating rubber core 23, and the first guide groove 231 and the second guide groove 232 are separated by the first retaining ring 233. The first guide groove 231 is provided on the outer wall away from the end of the plug inner tooth 32, and the second guide groove 232 is provided on the outer wall close to the end of the plug inner tooth 32. The insulating rubber core 23 is provided with a first positioning groove 234 near the first guide groove 231.

[0047] It is understood that the first guide groove 231 provided in the insulating rubber core 23 is used to install the insulating rubber core 23 into the inner cavity of the socket shell 24. The first guide groove 231 cooperates with the structure of the inner cavity of the socket shell 24 to limit the position of the insulating rubber core 23, preventing the insulating rubber core 23 from rotating within the inner cavity of the socket shell 24, which could cause the connection between the first connecting rod 22 and the terminal block to be disconnected. The provision of the first guide groove 231 also provides a foolproof function, ensuring that the multiple first connecting rods 22 in the insulating rubber core 23 always maintain the same position. When connecting the insulating rubber core 23 to the plug inner thread 32, there is no need to repeatedly confirm the positions of the multiple first connecting rods 22 and the multiple second connecting rods 34, allowing for quick connection of the insulating rubber core 23 and the plug inner thread 32.

[0048] It can be understood that the second guide groove 232 provided on the insulating rubber core 23 can limit the connection between the insulating rubber core 23 and the inner thread 32 of the plug by cooperating with the structure of the second guide groove 232 and the inner thread 32 of the plug, thereby avoiding incorrect insertion of the first connecting rod 22 and the second connecting rod 34, and increasing the insertion efficiency of the insulating rubber core 23 and the inner thread 32 of the plug.

[0049] It can be understood that when the insulating rubber core 23 is installed in the inner cavity of the socket shell 24, the first retaining ring 233 is provided to prevent water vapor from entering the inner cavity of the socket shell 24, or by installing a waterproof pad at the position where the first retaining ring 233 and the inner cavity of the socket shell 24 are connected, it can be prevented that water vapor enters the inner cavity of the socket shell 24 along the insulating rubber core 23, causing oxidation or short circuit between the first connecting rods 22, thereby damaging the connector.

[0050] It can be understood that when the insulating rubber core 23 is installed in the inner cavity of the socket shell 24, the insulating rubber core 23 can be limited by the structural cooperation between the first positioning groove 234 and the inner cavity of the socket shell 24, so as to prevent the first connecting rod 22 and the first wire terminal 21 in the inner cavity of the insulating rubber core 23 from falling off when the insulating rubber core 23 and the inner teeth 32 of the plug are plugged in and out.

[0051] Preferably, the inner thread 32 of the plug is provided with a guide rail 312, the position of the guide rail 312 corresponds to the position of the second guide groove 232, a second retaining ring 321 is provided around the outer wall of the inner thread 32 of the plug, and the end of the insulating rubber core 23 close to the inner thread 32 of the plug is inserted into the inner thread 32 of the plug for sleeve connection.

[0052] It can be understood that the insulating rubber core 23 is inserted into the inner thread 32 of the plug, and the first connecting rod 22 and the second connecting rod 34 are electrically connected. By providing a guide rail 312 in the inner cavity of the inner thread 32 of the plug to cooperate with the second guide groove 232 provided on the insulating rubber core 23, incorrect insertion of multiple first connecting rods 22 and multiple second connecting rods 34 is avoided, thereby increasing the insertion efficiency of the insulating rubber core 23 and the inner thread 32 of the plug.

[0053] It can be understood that when the plug inner teeth 32 are installed in the inner cavity of the plug shell 31, the second retaining ring 321 is provided to prevent water vapor from entering the inner cavity of the plug shell 31, or by installing a waterproof pad at the position where the second retaining ring 321 and the inner cavity of the plug shell 31 are connected, it is possible to prevent water vapor from entering the inner cavity of the plug shell 31 along the plug inner teeth 32, causing oxidation or short circuit between the second connecting rods 34, and damaging the connector.

[0054] Specifically, the first connecting rod 22 passing through the insulating rubber core 23 is electrically connected to the disconnected first cable 4 and the second cable 5 through multiple first connecting terminals 21, and the second connecting rod 34 passing through the inner teeth of the plug 32 is electrically connected to the disconnected first cable 4 and the second cable 5 through multiple second connecting terminals 35. When the socket shell 24 and the plug shell 31 are socketed, the multiple first connecting rods 22 and the multiple second connecting rods 34 are electrically connected respectively, so that the disconnected first cable 4 and the second cable 5 are conductive.

[0055] Preferably, the socket shell 24 is used to fix the insulating rubber core 23. The socket shell 24 is provided with a guide block 245 and a positioning buckle 241. The position of the guide block 245 corresponds to the first guide groove 231, the position of the positioning buckle 241 corresponds to the first positioning groove 234, and the outer wall of the socket shell 24 is provided with a second positioning groove 242.

[0056] It can be understood that the insulating rubber core 23 is installed in the inner cavity of the socket shell 24, and the guide block 245 and the first guide groove 231 cooperate to prevent the insulating rubber core 23 from rotating in the inner cavity of the socket shell 24, causing the electrical connection between the first connecting rod 22 and the first terminal 21 to be broken.

[0057] It can be understood that the first positioning groove 234 is engaged by the positioning buckle 241 to limit the insulating rubber core 23, thereby preventing the first connecting rod 22 and the first terminal 21 in the inner cavity of the insulating rubber core 23 from falling off when the insulating rubber core 23 and the inner teeth 32 of the plug are plugged in and out.

[0058] Preferably, the plug shell 31 is used to fix the socket shell 24 and the plug inner teeth 32. The plug shell 31 is provided with a spring buckle 311. The end of the socket shell 24 close to the second positioning groove 242 is sleeved on the plug shell 31. The position of the spring buckle 311 corresponds to the position of the second positioning groove 242.

[0059] It is understood that when the connector 2 and connector 3 are connected, the socket housing 24 is inserted into the plug housing 31, electrically connecting the first connecting rod 22 and the second connecting rod 34. Simultaneously, a spring latch 311 provided on the plug housing 31 engages with a second positioning slot 242 provided on the socket housing 24. The spring latch 311 and the second positioning slot 242 cooperate to position the socket housing 24 and the plug housing 31, preventing them from falling off due to external forces, which could cause the connector to disconnect.

[0060] It will be appreciated that when the socket housing 24 is inserted into the plug housing 31, the multiple first connecting rods 22 extending through the insulating rubber core 23 and the multiple second connecting rods 34 extending through the plug inner threads 32 are simultaneously electrically connected. Therefore, by connecting or disconnecting the socket housing 24 and the plug housing 31, the multiple first connecting rods 22 and the multiple second connecting rods 34 are switched between open and closed states, thereby switching the connection between the first cable 4 and the second cable 5. Because the first connecting rods 22 extend through the insulating rubber core 23 within the socket housing 24, and the second connecting rods 34 extend through the plug inner threads 32 within the plug housing 31, when the socket housing 24 and the plug housing 31 are connected, moisture oxidation of the first and second connecting rods 22 and 34 is prevented, which could affect the electrical conductivity between the first and second connecting rods 22 and 34 and shorten the service life of the connector.

[0061] Preferably, a waterproof rubber pad 243 is installed at the end of the socket housing 24 inserted into the plug housing 31 , and a waterproof cover 244 is provided on the outer wall of the socket housing 24 , which can be buckled with the socket housing 24 .

[0062] It can be understood that by installing a waterproof rubber pad 243 at one end of the socket shell 24 inserted into the plug shell 31, it is possible to effectively prevent water vapor from entering the connector along the gap between the socket shell 24 and the plug shell 31, thereby causing oxidation or short circuit between the first connecting rod 22 and the second connecting rod 34, and damaging the connector.

[0063] It can be understood that the socket housing 24 is provided with a waterproof cover 244, and the size of the waterproof cover 244 corresponds to the socket housing 24. When the connecting socket 2 is not in use, the waterproof cover 244 can be snapped onto the socket housing 24, and the snapping position of the socket housing 24 is filled with the waterproof cover 244 to prevent water vapor from oxidizing the first connecting rod 22 and reducing the conductivity of the first connecting rod 22.

[0064] Preferably, the connector 3 also includes a plug waterproof tail 33, one end of which is socketed on the plug shell 31 and fixedly connected to the plug inner thread 32 by a thread. The plug waterproof tail 33 is fixed with a first nut 331. When the plug waterproof tail 33 is connected to the plug inner thread 32, the first nut 331 squeezes the plug shell 31.

[0065] It is understood that the end of the plug inner thread 32 away from the insulating rubber core 23 is provided with an external thread, and the plug waterproof tail 33 is fixedly connected to the plug inner thread 32 via the internal thread. When the plug waterproof tail 33 and the plug inner thread 32 are fixedly connected via the thread, the connection position of the plug waterproof tail 33 and the plug inner thread 32 is within the inner cavity of the plug shell 31. The first nut 331 of the plug waterproof tail 33 is tightly attached to the plug shell 31, preventing moisture from entering the inner cavity of the plug shell 31 through the gap between the first nut 331 and the plug shell 31, which could cause oxidation of the second connecting rod 34. Alternatively, when the first nut 331 of the plug waterproof tail 33 is tightly attached to the plug shell 31, a waterproof gasket is provided between the first nut 331 and the plug shell 31 to prevent moisture from entering the plug shell 31 through the gap between the first nut 331 and the plug shell 31, which could cause oxidation of the second connecting rod 34 and affect its conductivity.

[0066] Preferably, a waterproof ring 332 surrounding the second cable 5 is provided at one end of the plug waterproof tail 33 away from the plug inner teeth 32 , and when the second nut 333 is fixedly connected to the plug waterproof tail 33 , the first nut 331 and the second nut 333 squeeze the waterproof ring 332 .

[0067] It can be understood that the waterproof tail 33 of the plug is installed with a waterproof ring 332 arranged around the second cable 5. The waterproof ring 332 is arranged in a 'convex' shape and is placed between the first nut 331 and the second nut 333. When the second nut 333 is threadedly fixed to the waterproof tail 33 of the plug, the waterproof ring 332 is squeezed by the first nut 331 and the second nut 333 to prevent water vapor from entering the cavity of the waterproof tail 33 of the plug along the gap between the first nut 331 and the second nut 333. At the same time, it can also prevent water vapor from oxidizing the second connecting rod 34 by passing through the waterproof tail 33 of the plug and the inner teeth 32 of the plug in turn along the second cable 5, thereby damaging the connector.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
