Description

Technical Field

[0002] A radio frequency coaxial connector, abbreviated as an RF connector, is a component installed on a cable or on an instrument in the communication industry for electrical connection or separation of a transmission line. It belongs to the products in the field of mechatronics. With the development of time, the RF connector has currently formed an independent and complete professional system and has become an important part of the connector family. It is an indispensable key component in the coaxial transmission system. However, during the use of the current radio frequency coaxial connector, when the two connectors are plugged together, the stability is poor. Under the action of a certain external force, the two are prone to separation, thus affecting the normal transmission of signals. Moreover, there is a lack of corresponding protection structure on the connector, which affects the service life of the coaxial connector. Therefore, we propose a radio frequency coaxial connector with good sealing performance to solve the above problems. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment

[0025] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, a radio frequency coaxial connector with good sealing performance proposed by an embodiment of the present utility model includes a first connector 1 and a second connector 2. The first connector 1 and the second connector 2 are inserted into each other. A first sealing component 3 and a second sealing component 4 are arranged between the first connector 1 and the second connector 2. A square plate 5 is fixed on the surface of the first connector 1. Two shells 6 are fixed on one side wall of the square plate 5. A rotating shaft 7 is rotatably connected to the inside of each shell 6 through a bearing. Gears 8 are fixed on the surfaces of the rotating shafts 7. Two racks 9 are slidably connected to one side wall of the square plate 5. The racks 9 are respectively meshed with the corresponding gears 8. Two first springs 10 are fixed inside each shell 6. The top ends of the first springs 10 are respectively fixed to the corresponding racks 9. A pressing plate 11 slidably penetrates through the tops of the two shells 6. The bottom of the pressing plate 11 is fixed to the tops of the two racks 9. An annular plate 12 is fixed on the surface of the second connector 2. Two connecting plates 19 are fixed on one side wall of the annular plate 12. Anti-slip ridges are evenly fixed on the surfaces of the connecting plates 19, which facilitates the staff to hold the second connector 2 and insert it into the first connector 1. The anti-slip ridges can increase the friction between the hand and the surface of the connecting plate 19, thus achieving an anti-slip effect. Two inserting plates 13 are fixed on one side wall of the annular plate 12. Slots 14 are opened at the tops of the inserting plates 13. The two inserting plates 13 respectively slide through the corresponding shells 6 and extend into their interiors. Blocks 15 adapted to the slots 14 are fixed on the surfaces of the rotating shafts 7. The blocks 15 are respectively clamped inside the corresponding slots 14. Wire protection components 16 are arranged at one ends of the first connector 1 and the second connector 2. When it is necessary to separate the first connector 1 and the second connector 2 when using this radio frequency coaxial connector, the pressing plate 11 can be pressed. When the pressing plate 11 moves, it can drive the two racks 9 to move downward. When the racks 9 move downward, the first springs 10 at this time will be in a compressed state, and when the racks 9 move downward, they will drive the gears 8 to rotate. When the gears 8 rotate, they can drive the blocks 15 to flip through the rotating shafts 7. Finally, the two flipped blocks 15 will respectively disengage from the slots 14 opened on the inserting plates 13. At this time, the first connector 1 and the second connector 2 can be separated. During installation, repeat the above operations. After the two inserting plates 13 are respectively inserted into the corresponding shells 6, release the pressing plate 11. At this time, under the restoring force of the compressed first springs 10, the racks 9 can automatically reset. After the racks 9 are reset, they can indirectly drive the blocks 15 to flip and re-clamp inside the slots 14. At this time, the two can be connected and fixed.

[0026] As Figure 5As shown in the figure, there is another way for the wire protection component 16 that protects the wire harnesses of connector 1 and connector 2 in the present utility model. It mainly includes mounting rings 20 respectively fixed on the surfaces of connector 1 and connector 2. Guide rings 21 are fixed on the surfaces of the wire harnesses of connector 1 and connector 2. T-shaped rubber rods 22 are arranged inside the through holes formed in an annular array in the two guide rings 21, and the other ends of the T-shaped rubber rods 22 are respectively fixedly connected to the corresponding mounting rings 20. When in use, under the action of the T-shaped rubber rods 22, the bending and stretching degrees of the roots of the wire harnesses can be limited and protected, thereby avoiding the situation that they break from the roots.

[0027] As Figure 2 shown, in some embodiments, the first sealing component 3 includes a conical shell 301 fixed to one end of connector 1. A first sealing ring 302 is fixed to the inner wall of the conical shell 301. A sealing ring 303 is closely attached inside the first sealing ring 302, and the sealing ring 303 is fixedly connected to connector 2. When in use, when connector 1 and connector 2 are plugged together, at this time the conical shell 301 will be in contact with the sealing ring 303, and then with the cooperation of the first sealing ring 302, the first sealing effect on the connected connector 1 and connector 2 can be achieved.

[0028] As Figure 2 shown, in some embodiments, the second sealing component 4 includes a sealing shell 401 fixed to the surface of connector 1. A sealing seat 402 adapted to the sealing shell 401 is fixed to the surface of connector 2. The sealing seat 402 is plugged into the inside of the sealing shell 401. A second sealing ring 403 is fixed to one side wall of the sealing seat 402, and the other side of the second sealing ring 403 is closely attached to the sealing shell 401. When in use, when connector 1 and connector 2 are plugged together, at this time the sealing seat 402 will be plugged into the inside of the sealing shell 401, and then with the cooperation of the second sealing ring 403, the secondary sealing effect on the connected connector 1 and connector 2 can be achieved.

[0029] As Figure 1 shown, in some embodiments, the wire protection component 16 includes support rings 1601 respectively fixed to one ends of connector 1 and connector 2. Limiting rings 1602 are fixed to the surfaces of the wire harnesses of connector 1 and connector 2. Second springs 1603 are fixed to one side walls of the support rings 1601, and the other ends of the second springs 1603 are respectively fixedly connected to the corresponding limiting rings 1602. When in use, the provided second springs 1603 can limit and buffer the bending and stretching degrees of the roots of the wire harnesses, thereby avoiding the situation that the roots of the wire harnesses break.

[0030] As Figure 3 and Figure 5As shown, in some embodiments, two T-shaped grooves 17 are formed on one side wall of the square plate 5, and T-shaped plates 18 adapted to the T-shaped grooves 17 are fixed on one side wall of the rack 9, which can support and guide the rack 9, so that it will be more stable during the up and down movement.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
