Description

Technical Field

[0001] This invention relates to the field of cable connector technology, specifically to a cable connector with sealing capability. Background Technology

[0002] In the field of modern power transmission and signal transmission, cables are used as a key transmission medium and are widely used in many industries such as power systems, communication networks, industrial automation, rail transportation and marine engineering. As various industries continue to increase their requirements for system stability and reliability, cable connectors, as important components for realizing electrical connections between cables or between cables and equipment, directly affect the operational safety of the entire transmission system.

[0003] For example, CN105790020B discloses a cable connector with sealing capability, including a cable and internal conductors, a plug, and a socket. The plug includes a first insulating fixing seat, a first connecting hole, a first connecting wire, and pins. The socket includes a second insulating fixing seat, a second connecting hole, a second connecting wire, and a conductive fixing sleeve. This cable connector with sealing capability has a simple structure and powerful function. By inserting the plug into the socket, a quick plug-in connection is achieved without the need for knobs and threaded locking, thereby improving the efficiency of cable connection. Since the first insulating fixing seat in the plug is glued to the cable, and the second insulating fixing seat in the socket is glued to the cable, and the inner diameter of the first insulating fixing seat is equal to the outer diameter of the second insulating fixing seat, the plug and socket are in close contact, minimizing the gap between the waterproof lines, thereby achieving waterproofing and effectively preventing cable leakage.

[0004] While existing cable connectors can meet the needs of use, during use, the cables are often long when laid, and the tension generated by the cable's own weight can easily cause the connector to detach, creating gaps that allow dust to enter and reduce its service life. At the same time, in areas with high electromagnetic intensity, electromagnetic waves can severely affect the battery signal inside the cable, resulting in a significant reduction in transmission efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a cable connector with sealing capability to solve the problems mentioned in the background art, such as the ease with which existing cable connectors can detach and are susceptible to electromagnetic waves.

[0009] Preferably, the outer limiting block has side grooves at the center of both the front and rear walls, and a triangular inner groove is formed at the center of the top of the outer limiting block.

[0010] Preferably, the outer sealing element includes an outer pipe and an upper injection pipe. The outer pipe has an outer annular groove formed inward on both ends of its annular wall. The outer annular groove engages with an outer extension ring block. The upper injection pipe is installed through the center of the top end of the outer pipe. The top end of the upper injection pipe is provided with a sealing plug. Inner limiting blocks are fixed on the upper and lower sides of both ends of the outer pipe. The inner limiting blocks have the same structure as the outer limiting blocks and are installed horizontally.

[0011] Preferably, the inner sealing element includes an inner pipe and an anti-magnetic element. The anti-magnetic element is fixedly disposed on the outer side of the center of the inner pipe. The top edge of the anti-magnetic element is fixedly disposed on the inner wall of the outer pipe. Both sides of the anti-magnetic element are connected with annular sealing bags. After the two sets of annular sealing bags are injected with mercury, they can be piled up and cover the outer pipe and the inner side of the outer extended ring block.

[0012] Preferably, the antimagnetic component includes a hollow ring block and a lower injection pipe. The lower injection pipe extends inward from the top of the hollow ring block, and the top of the lower injection pipe is connected to the upper injection pipe. Side pipes are installed on both inner walls of the top of the hollow ring block to connect to annular sealing bags. Guide rails are installed on both inner walls of the two sets of side pipes. A piston is installed at the point where the top of the hollow ring block connects to the inner pipe, and a piston rod is slidably provided at the center of the piston.

[0013] Preferably, a connecting plate is fixed to the top of the piston rod, and baffles are fixed to both ends of the connecting plate. Both sets of baffles slide and rise within the guide rail. A drainage port is opened downward on the front side of the top of the connecting plate and the piston rod. A plastic plate is installed at the bottom of the piston rod, and the plastic plate floats in mercury.

[0014] Preferably, the inner sides of the middle cable are provided with openings, and both ends of the middle cable are provided with external fixing plates for support and fixation. The external fixing plates are provided with docking holes at the connection between the external fixing plates and the two ends of the middle cable, and four sets of permeation holes are provided on the side of the external fixing plates.

[0015] Preferably, the locking component includes a locking box and a lead screw. Side blocks are fixedly provided at both the front and rear of the bottom end of the locking box. The two sets of side blocks slide on the sides of the outer and inner limit blocks. A side plate is fixedly provided at the right end of the locking box. A lead screw is installed at the center of the side plate. Four sets of U-shaped frames are installed inside the locking box.

[0016] Preferably, the left end of the lead screw moves to the left via the screw drum thread, and the lead screw can push the triangular locking block to be locked in the corresponding outer and inner limiting blocks on the bottom side, with the bottom side of the lead screw abutting the top of the triangular locking block.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The left cable, right cable and connector are connected and fixed by a triangular block controlled by locking and internal torsion spring. This effectively limits the installation and reduces the risk of the cables from falling off due to pulling. Mercury is filled into the annular sealing bag and the inner pipe in the inner seal. This effectively protects and isolates the connector from external electromagnetic waves and dust without affecting the transmission.

[0019] 2. By setting the pins installed inside the insert head, it can be connected to the middle port of the cable, thereby improving the connection efficiency and conveying efficiency. The outer limit block and inner limit block fixed at the upper and lower ends of the insert head and the outer seal can be positioned, thereby facilitating locking and improving installation efficiency. The one-way locking triangular block installed in the locking box locks under the movement of the screw. By locking the left cable, right cable and connector simultaneously, the connection is fixed, thereby improving the connectivity between them.

[0020] 3. An expandable annular sealing bag is provided in the center of the inner and outer pipes to protect and buffer the internal cable, further improving usability. The mercury poured into the anti-magnetic component can generate a reverse current through electromagnetic induction, thereby canceling electromagnetic waves and playing a shielding role. The mercury poured into the middle cable can protect the cable without affecting its operation. The mercury seal can seal the interior and prevent the risk of dust entering.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-9 This invention provides an embodiment of a cable connector with sealing capability, comprising a left cable 1 and a right cable 2, which are identical in structure and mirror-mounted. Both ends of the left cable 1 are provided with insertion heads 11, which can be inserted parallel to each other into a connecting mechanism 3. The connecting mechanism 3 includes a middle cable 33, whose ends can be connected to the left cable 1 and the right cable 2. The connecting mechanism 3 has an inner sealing element 32 to protect the connection point, and an outer sealing element 31 for further sealing and protection. Locking elements 4 are provided at both the upper and lower ends of the connecting mechanism 3 to connect and fix the left cable 1 and the right cable 2.

[0034] The insertion head 11 includes a mounting ring block 111 and an outer extension ring block 112. The mounting ring block 111 is installed at both ends of the left cable 1. The outer extension ring block 112 is fixed to the outer wall of the mounting ring block 111 and can be sealed and fitted in the outer sealing member 31. The center of the mounting ring block 111 is provided with a pin 114 for connection with the cable, and the inner side of the outer wall of the mounting ring block 111 is fixed with an inner extension ring block 113. The inner extension ring block 113 can be mated and fitted at the connection between the inner sealing member 32 and the middle cable 33. The upper and lower ends of the mounting ring block 111 are both fixed with outer limiting blocks 12. The center of the front and rear walls of the outer limiting blocks 12 are provided with side grooves 121, and the center of the top of the outer limiting blocks 12 is provided with a triangular inner groove 122. The inner sides of the middle cable 33 are provided with through holes 331, and the two ends of the middle cable 33 are provided with outer fixing plates 332 for support and fixation. The outer fixing plate 332 and the two ends of the middle cable 33 are provided with mating holes 334, and four sets of penetration holes 333 are provided on the side of the outer fixing plate 332. The above design can realize the connection between cables and improve the transmission stability.

[0035] The outer sealing element 31 includes an outer pipe 310 and an upper injection pipe 312. The outer pipe 310 has an outer annular groove 311 formed inwards on both ends of its annular wall. The outer annular groove 311 engages with an outer extension ring block 112. The upper injection pipe 312 is installed through the center of the top end of the outer pipe 310. A sealing plug 313 is provided at the top end of the upper injection pipe 312. Inner limiting blocks 314 are fixed to the upper and lower sides of both ends of the outer pipe 310. The inner limiting blocks 314 have the same structure as the outer limiting blocks 12 and are installed horizontally, which is beneficial for installing the left cable 1 and the right cable 2 and improving sealing.

[0036] The inner sealing element 32 includes an inner pipe 320 and an anti-magnetic element 321. The anti-magnetic element 321 is fixedly installed on the outer side of the center of the inner pipe 320. The top edge of the anti-magnetic element 321 is fixed to the inner wall of the outer pipe 310, and annular sealing bags 322 are connected to both sides of the anti-magnetic element 321. After the two sets of annular sealing bags 322 are filled with mercury, they can accumulate and cover the inner side of the outer pipe 310 and the outer extension ring block 112. The anti-magnetic element 321 includes a hollow ring block 3210 and a lower injection pipe 3211. The lower injection pipe 3211 extends inward from the top of the hollow ring block 3210, and the top of the lower injection pipe 3211 is connected to the upper injection pipe 312. Side pipes 3212 are installed on both inner walls of the top of the hollow ring block 3210 to connect to the annular sealing bags 322, and guide rails 3214 are installed on both inner walls of the two sets of side pipes 3212. A piston 3213 is installed at the top of the hollow annular block 3210 where it connects to the inner pipe 320. A piston rod 3216 is slidably mounted at the center of the piston 3213. A connecting plate 3218 is fixed to the top of the piston rod 3216, and baffles 3219 are fixed to both ends of the connecting plate 3218. Both sets of baffles 3219 slide and rise within the guide rail 3214. A drain port 3217 is opened downwards on the front side of the top of the connecting plate 3218 and the piston rod 3216. A plastic plate 3215 is installed at the bottom of the piston rod 3216. The plastic plate 3215 floats in mercury. This design helps to fill the inner pipe first before filling the annular sealing bag, thereby improving the protective effect.

[0037] The locking component 4 includes a locking box 41 and a lead screw 42. Side blocks 411 are fixedly provided at the front and rear of the bottom end of the locking box 41. The two sets of side blocks 411 slide on the sides of the outer limit block 12 and the inner limit block 314. A side plate 412 is fixedly provided at the right end of the locking box 41. A lead screw 413 is installed at the center of the side plate 412. Four sets of U-shaped frames 414 are installed inside the locking box 41. Triangular blocks 415 are installed inside each U-shaped frame 414 using torsion springs. The bottom ends of the four sets of triangular blocks 415 are perpendicular to the top ends of the outer limit block 12 and the inner limit block 314. The left end of the lead screw 42 moves to the left through the thread of the lead drum 413. The lead screw 42 can push the triangular locking block 415 to lock in the corresponding outer limit block 12 and inner limit block 314 on the bottom side. The bottom side of the lead screw 42 is in contact with the top of the triangular locking block 415. The upward design is beneficial for connecting and fixing the left cable, right cable and connector, thereby improving the connectivity between them.

[0038] Working principle: During operation, when needed, first insert the inner plugs 11 of the left cable 1 and right cable 2 into the two ends of the middle cable 33 respectively. The outer extension ring block 112 inside the plug 11 fits into the outer annular groove 311 on both walls of the outer pipe 320, while the central pin 114 can be inserted into the opening 331 of the middle cable 33. At the same time, the outer limiting block 12 fixed at the upper and lower ends of the plug 11 and the inner limiting block 314 fixed at the upper and lower ends of the outer pipe 310 are kept at the same level.

[0039] Then, remove the sealing plug 313 installed at the top of the outer pipe 310 in the upper injection pipe 312. Using a tool, inject mercury through the upper injection pipe 312 and the bottom injection pipe 3211 into the hollow ring block 3210. Once the mercury in the hollow ring block 3210 reaches the upper side of the piston 3213, it is injected into the inner pipe 320 through the drain port 3217 at the front end of the piston rod 3216 and connecting plate 3218. When the inner pipe 320 is full of mercury, it will cause the plastic plate 3215 at the bottom of the piston rod 3216 to rise. The rising of the plastic plate 3215 will then cause the piston rod 3216 to rise. The rising of the piston rod 3216 will cause the baffles 3219 on both sides to rise under the limit of the guide rail 3214. After rising, the baffles 3219 will protrude from the side pipe 3212. Mercury can be fed into the annular sealing bag 322 through the side pipes 3212 on both sides. After the annular sealing bag 322 is filled with mercury, it will fill the space in the center of the outer pipe 310 and the inner pipe 310. Finally, after filling, the sealing plug 313 is installed.

[0040] Finally, the two sets of side blocks 411 on the bottom of the locking box 41 are slidably installed in the side groove 121 opened in the right outer limit block 12. After installation, the lead screw 42 can be extended inward through the lead cylinder 413. When the lead screw 42 extends, it abuts against the triangular locking block 415 and is locked in the corresponding triangular groove 122 under the spring of the torsion spring. When the lead screw 42 is rotated to the leftmost position, the left cable 1, the right cable 2 and the connecting mechanism 3 can be locked.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
