Description

Technical Field

[0001] The invention relates to the technical field of coaxial cables, in particular to a coaxial cable connector. Background Art

[0002] Coaxial cable is a cable for transmitting electrical signals. Its structure includes an inner conductor surrounded by an insulating layer, followed by an outer conductor and an outer insulating layer. This design enables coaxial cable to transmit signals at high frequencies while effectively reducing signal interference. Connectors are used to connect the two ends of a coaxial cable or to connect a coaxial cable to other devices. Connectors usually consist of two parts: a plug and a socket. The plug connects one end of the coaxial cable and the socket connects the other end or other devices. Connectors provide a convenient and reliable way to connect coaxial cables and ensure the quality and stability of signal transmission.

[0003] The existing coaxial cable connector uses threads to connect the male and female heads, ensuring the stability and reliability of the signal during transmission. The male part has external threads, while the female part has internal threads. When connected, the male head is screwed into the female head, and the two are tightly fixed through the bite of the threads. However, during the connection process, if the threads are not aligned correctly or the tightening force is insufficient, the connection will become loose or the contact will be poor, which will affect the quality of signal transmission.

[0008] Preferably, the fixing assembly includes a swivel, a cavity is provided inside the connecting piece, a side wall of the swivel is rotatably connected inside the cavity, and an anti-slip groove is provided on the side wall of the swivel.

[0009] Preferably, a sleeve is fixedly connected inside the swivel, an arc-shaped groove is opened inside the swivel, a rotating shaft is arranged inside the anti-slip groove, a side wall of the rotating shaft is slidably connected inside the arc-shaped groove, and the side wall of the rotating shaft is fixedly connected inside the connecting piece.

[0010] Preferably, a second arc-shaped groove is provided inside the collar, and a rotating frame is rotatably connected inside the collar, and the rotating frame is arranged inside the second arc-shaped groove.

[0011] Preferably, the side wall of the rotating shaft is rotatably connected to a clamping plate, the side wall of the clamping plate is slidably connected to the inside of the rotating frame, and the side wall of the clamping plate is fixedly connected to a rubber ball.

[0012] Preferably, the limiting assembly comprises a fixed plate, a shifting plate is rotatably connected between the fixed plates, an auxiliary plate is fixedly connected to a side wall of the shifting plate, and a connecting column is fixedly connected to the side wall of the shifting plate.

[0013] Preferably, the side wall of the shift plate is fixedly connected to a limit plate, the left side of the bottom of the limit plate is arranged in an arc surface, the limit plate is engaged with the anti-skid groove, and the surface where the anti-skid groove fits with the arc surface of the limit plate is arranged in an arc surface.

[0014] Preferably, a second spring is provided between the connecting column and the connecting member, one end of the second spring is fixedly connected to the side wall of the connecting member, and the other end of the second spring is fixedly connected to the side wall of the connecting column.

[0015] Working principle: When installing the male and female connectors, the worker first places the coaxial cable inside the male connector and places the cable between the clamps. At this time, the worker rotates the swivel clockwise to drive the internally connected ring to rotate. The ring will drive the rotating frame to move when it rotates. The rotating frame will deflect inside the arc groove 2 under the restriction of the clamp. The clamp will move under the action of the deflection of the swivel frame. The clamp will deflect around the shaft at this time. At this time, the other side of the clamp will gradually approach, so that the rubber ball fits the coaxial cable and deforms the rubber ball to fix the coaxial cable, so that the coaxial cable and the male connector are stably connected. When the swivel is rotated clockwise, the arc surface of the anti-skid groove will contact the arc surface of the limit plate, and the limit plate will be pushed up as it rotates. The limit plate will drive the paddle plate to move upward, causing it to rotate between the fixed plates and causing the second spring to stretch and deform. When the swivel stops rotating, the second spring loses its tension to reset and pull the paddle plate downward to deflect, causing the limit plate to re-engage the anti-skid groove. When the coaxial cable needs to be removed from the inside of the male connector, the paddle plate can be pulled upward by the auxiliary plate to separate the limit plate from the anti-skid groove, and then the connector can be rotated counterclockwise to gradually separate the splints. The coaxial cable loses the force squeezed by the fixed plate and can be pulled out from the inside of the male connector to complete the removal. When the swivel is turned counterclockwise without pulling the auxiliary plate upward, the straight surface of the anti-slip groove will fit with the straight surface of the limit plate and restrict each other, so that the swivel cannot be rotated. This ensures that once the coaxial cable is fixed, the connection between the male head and the coaxial cable will not loosen due to vibration or long-term aging. When the male head and the coaxial cable are connected, the sliding pull ring squeezes the first spring to shrink it, and then the male head is inserted into the female head. During the insertion process, the arc surface at the front end of the male head will push the card ball upward, and when the arc plate on the side wall of the male head moves to fit with the inner card ring inside the female head, the card slot opened inside the male head will just move to the inside of the concave hole. , and then release the pull ring. At this time, the first spring loses pressure and resets, and pushes the pull ring forward. When the pull ring is reset, it will squeeze the card ball into the inside of the card slot to fix the male head. When the male head and the female head are connected and fixed, the positioning block on the side wall of the male head will just fit into the inside of the positioning slot. After the pull ring is reset, the sealing ring will fit with the sealing ring to achieve a sealing effect, thereby preventing the entry of dust and moisture into the coaxial cable during use, thereby extending the service life of the coaxial cable. When the male head needs to be removed from the female head, the first spring is contracted by sliding the pull ring. The top of the card ball will lose its restriction at this time, so that the male head can be directly pulled outward to complete the disassembly.

[0016] The present invention provides a coaxial cable connector having the following beneficial effects: 1. The present invention achieves the effect of quickly connecting the male head and the female head through the cooperation between the limit ring, the slot, the connecting piece, the pull ring, the first spring, the concave hole and the card ball, making the connection process more convenient and efficient, and solving the problem that the male head and the female head are connected by threads in the prior art, and the number of rotations needs to be manually controlled. Too tight will cause the thread to deform and wear, affecting the service life of the equipment, and too loose will result in an unstable connection, which is easy to loosen and affect the use of the equipment. The above scheme not only improves the connection efficiency, but also greatly reduces the operating difficulty for users.

[0017] 2. The present invention achieves the effect of quickly fixing the coaxial cable when the male connector and the coaxial cable are fixed by the coordination among the structures such as the sleeve ring, the first arc groove, the rotating shaft, the second arc groove, the clamping plate, the rotating frame and the rubber ball, thereby solving the problem in the prior art that the coaxial cable is fixed by squeezing the connecting ring to deform it, which is troublesome.

[0018] 3. The present invention achieves the effect of limiting the swivel and preventing it from being reset without human interference through the cooperation among the anti-slip groove, the fixing plate, the paddle plate, the auxiliary plate, the connecting column, the second spring and the limit plate, thereby ensuring the firmness of the coaxial cable fixation and solving the problem in the prior art of fixing the coaxial cable with a single connecting ring, which becomes loose after long-term wear. The above scheme improves the stability of the coaxial cable fixation.

[0019] 4. The present invention achieves the effect of improving the sealing of the equipment through the coordination between the positioning groove, positioning block, sealing ring and sealing ring structures, solves the problem of poor sealing after the male head and the female head are connected in the prior art, and improves the stability and reliability of the equipment through the above solution.

DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying drawings of the present invention to clearly and completely describe the technical solution of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example: Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 The embodiment of the present invention provides a coaxial cable connector, including a male head 1 and a female head 2, wherein the male head 1 is slidably connected to the inside of the female head 2, a fixing sleeve 32 is fixedly connected to the inside of the female head 2, a pinhole 33 is provided inside the fixing sleeve 32, a limiting ring 3 is fixedly connected to the side wall of the male head 1, a radian plate 34 is fixedly connected to the side wall of the limiting ring 3, a card slot 4 is provided inside the male head 1, a connecting piece 5 is fixedly connected to the side wall of the male head 1, a fixing component is provided inside the connecting piece 5, a limiting component is provided on the side wall of the connecting piece 5, a pull ring 6 is slidably connected to the side wall of the female head 2, and the female A first spring 7 is sleeved on the side wall of the head 2, one end of the first spring 7 is fixedly connected to the side wall of the pull ring 6, and the other end of the first spring 7 is fixedly connected to the side wall of the female head 2. A recessed hole 8 is opened inside the female head 2, and the recessed hole 8 is larger at the top and smaller at the bottom. A card ball 9 is arranged inside the female head 2, and the card ball 9 is arranged inside the recessed hole 8. The side wall of the card ball 9 is slidably connected to the inside of the card groove 4. An inner snap ring 10 is fixedly connected to the inner wall of the male head 1, and the inner snap ring 10 is fitted with the radian plate 34. An anti-slip ring 11 is fixedly connected to the side wall of the pull ring 6, and a sealing assembly is arranged on the side walls of the female head 2 and the male head 1.

[0024] When the male connector 1 is connected to the coaxial cable, the staff can slide the pull ring 6 to squeeze the first spring 7 to shrink it. Next, insert the male connector 1 into the female connector 2. During this process, the curved surface at the front end of the male connector 1 will push the card ball 9 upward to ensure that the male connector 1 can be smoothly inserted into the female connector 2. This design makes the connection more stable. When the curved plate 34 on the side wall of the male connector 1 moves to fit the inner card ring 10 inside the female connector 2, the card slot 4 opened inside the male connector 1 will just move to the inside of the concave hole 8. Finally, release the pull ring 6 to restore the first spring 7 to its original state. During this process, the pull ring 6 will push forward to squeeze the card ball 9, squeeze the card ball 9 into the inside of the card slot 4, fix the male connector 1, and ensure that it remains stable during use.

[0025] Please refer to the attached Figure 1 , Attachment Figure 2 and attached Figure 4 The sealing assembly includes a positioning block 13, the side wall of the positioning block 13 is fixedly connected to the side wall of the male head 1, a positioning groove 12 is opened inside the female head 2, the side wall of the positioning block 13 is slidably connected inside the positioning groove 12, a sealing ring 14 is fixedly connected to the side wall of the female head 2, and a sealing ring 15 is fixedly connected to the inner wall of the pull ring 6, and the sealing ring 14 fits with the sealing ring 15.

[0026] When the male connector 1 and the female connector 2 are connected and fixed, the positioning block 13 on the side wall of the male connector 1 will fit into the positioning groove 12. This design makes the connection more stable and prevents accidental loosening. After the connection is completed, the pull ring 6 is reset, and the sealing ring 14 will fit tightly with the sealing ring 15 to form a complete sealed space. This design effectively prevents dust, water vapor and other impurities from entering the connector and damaging the stability of the connection.

[0027] Please refer to the attached Figure 1 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 7 The fixing assembly includes a swivel 16, a cavity 31 is opened inside the connecting member 5, the side wall of the swivel 16 is rotatably connected to the inside of the cavity 31, the side wall of the swivel 16 is opened with an anti-skid groove 24, a collar 17 is fixedly connected to the inside of the swivel 16, an arc groove 18 is opened inside the swivel 16, a rotating shaft 19 is arranged inside the anti-skid groove 24, the side wall of the rotating shaft 19 is slidably connected inside the arc groove 18, the side wall of the rotating shaft 19 is fixedly connected to the inside of the connecting member 5, an arc groove 20 is opened inside the collar 17, a rotating frame 22 is rotatably connected to the inside of the collar 17, the rotating frame 22 is arranged inside the arc groove 20, the side wall of the rotating shaft 19 is rotatably connected to the splint 21, the side wall of the splint 21 is slidably connected to the inside of the rotating frame 22, and the side wall of the splint 21 is fixedly connected to the rubber ball 23.

[0028] During the connection process of the coaxial cable, the coaxial cable is first placed inside the male connector 1 and between the clamping plates 21. Next, the operator rotates the swivel 16 clockwise, which is the driving force for the internally connected ring 17 to rotate. During the rotation of the ring 17, the rotating frame 22 will be driven to move. This movement process is carried out under the restriction of the clamping plate 21. The rotating frame 22 will deflect inside the arc groove 20. The deflection of the rotating frame 22 drives the movement of the clamping plate 21. At this time, the clamping plate 21 deflects around the rotating shaft 19. As the clamping plate 21 deflects, its other side will gradually approach. This approaching process makes the rubber ball 23 fit closely with the coaxial cable and causes the rubber ball 23 to deform. This deformation fixes the coaxial cable. This fixing effect enables the coaxial cable and the male connector 1 to be stably connected together, ensuring the firmness of the connection.

[0029] Please see attached Figure 1 , Attachment Figure 5 and attached Figure 8 The limiting assembly includes a fixed plate 25, between which a dial plate 26 is rotatably connected, a side wall of the dial plate 26 is fixedly connected to an auxiliary plate 27, a side wall of the dial plate 26 is fixedly connected to a connecting column 28, a side wall of the dial plate 26 is fixedly connected to a limiting plate 30, the left side of the bottom of the limiting plate 30 is arranged in an arc surface, the limiting plate 30 is engaged with the anti-skid groove 24, and the surface where the anti-skid groove 24 and the arc surface of the limiting plate 30 are in contact is arranged in an arc surface, a second spring 29 is arranged between the connecting column 28 and the connecting member 5, one end of the second spring 29 is fixedly connected to the side wall of the connecting member 5, and the other end of the second spring 29 is fixedly connected to the side wall of the connecting column 28.

[0030] When the coaxial cable needs to be removed from the female connector 2, the staff can pull the paddle plate 26 upwards through the auxiliary plate 27. This action will separate the limit plate 30 from the anti-skid groove 24. Then, the connector 5 is rotated counterclockwise. This process will gradually separate the clamping plate 21, allowing the coaxial cable to be pulled out from the inside of the male connector 1. If the swivel 16 is directly rotated counterclockwise without first pulling the auxiliary plate 27 upwards, the straight surface of the anti-skid groove 24 will fit with the straight surface of the limit plate 30, restricting each other and causing the swivel 16 to be unable to rotate. This method ensures that after the coaxial cable is fixed, the connection between the male connector 1 and the coaxial cable will not become loose due to vibration or long-term placement and aging. In the process of rotating the swivel 16 clockwise, the arc surface of the anti-skid groove 24 will come into close contact with the arc surface of the limit plate 30. As the rotation proceeds, the anti-skid groove 24 will push the limit plate 30 upwards. This process is interactive. When the limit plate 30 is lifted up, it will also drive the dial plate 26 to move upward. When the dial plate 26 rotates between the fixed plates 25, the second spring 29 will be stretched and deformed. This is because the rotation of the rotating ring 16 drives the movement of the limit plate 30 and the dial plate 26, so that the second spring 29 is subjected to the tensile force, ensuring the stability and accuracy of the rotation. When the rotating ring 16 stops rotating, the second spring 29 will lose the tension. Under the effect of the loss of tension, the dial plate 26 will deflect downward. The dial plate 26 will drive the limit plate 30 to move downward until the limit plate 30 is stuck back into the anti-slip groove 24.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
