Description

Technical Field

[0001] This utility model relates to the field of radio frequency coaxial connector technology, specifically to an anti-collision radio frequency coaxial connector. Background Technology

[0002] A shockproof RF coaxial connector is a connector designed to maintain a stable connection in environments with high vibration or high shock resistance.

[0003] The design of this connector focuses on improving the stability and durability of the connection, especially in radio frequency applications that require high reliability and durability. By adopting a special structural design and materials, the anti-collision radio frequency coaxial connector can effectively resist external shocks and vibrations, ensuring the continuity of signal transmission and the reliability of the device.

[0004] Radio frequency coaxial connectors installed and used in underground coal mines need to be separated during later equipment maintenance. Due to the relatively harsh underground environment, if dust enters the inside of the radio frequency coaxial connector during the separation process, it is difficult to detect and remove, which will affect the stability of the radio frequency coaxial connector after reconnection. Therefore, an anti-collision radio frequency coaxial connector is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an anti-collision radio frequency coaxial connector to solve the problem that when radio frequency coaxial connectors installed in underground coal mines need to be separated during equipment maintenance, the relatively harsh underground environment makes it difficult to detect and remove dust from the inside of the connector during separation, which can affect the stability of the connector after reconnection.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A collision-resistant radio frequency coaxial connector includes a plug and a socket. One end of the plug is fixedly connected to a guide shell, and a connecting shell is rotatably connected to the outside of the guide shell. The guide shell contains a plug core with a limiting ring groove on its inner side. The plug is connected to a connecting core fixedly connected to one end of the socket via the plug core. A connecting shell is located outside the connecting core. A sealing mechanism is connected inside the connecting shell via a fixing ring. Disassembly holes are provided on the inner sides of both ends of the fixing ring. The sealing mechanism includes a sealing cover with a baffle installed at one end. The connecting shell includes a housing with a positioning ring groove on the inner side of one end.

[0008] As a further optimization of this utility model, the inner side of the connecting shell is provided with an internal thread, the outer side of the connecting shell is provided with a threaded groove, and the connecting shell and the connecting shell are spirally connected.

[0009] As a further optimization of this utility model, the outer edge of the guide shell away from the connector is arc-shaped, the inner edge of the connecting shell away from the connector is arc-shaped, and the guide shell and the connecting shell are adapted to each other.

[0010] As a further optimization of this utility model, the sealing cover is cone-shaped, and the sealing cover has an opening at the baffle.

[0011] As a further optimization of this utility model, the sealing cover is installed inside the positioning ring groove on the side away from the baffle by a fixing ring, and the fixing ring has a notch in the middle.

[0012] As a further optimization of this utility model, the disassembly hole is provided in two parts, and the opening edge of the disassembly hole is arc-shaped.

[0013] As a further optimization of this utility model, the connector, connecting shell, guide shell, connector core, connector socket, and connecting core are all on the same axis.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, through the sealing mechanism, connecting shell, connecting outer shell, and fixing ring, when the connector and socket are separated later, the connector core can pull the sealing cover out from inside the connecting shell through the limiting ring groove. This prevents dust from entering the socket during the separation process, thus avoiding poor contact after reconnection. It has good stability, facilitates the replacement of the sealing cover later, and prevents the coaxial connection from loosening due to collision. Attached Figure Description

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A collision-resistant RF coaxial connector,

[0029] The device includes a connector 1 and a connector base 6. One end of the connector 1 is fixedly connected to a guide shell 3. A connecting shell 2 is rotatably connected to the outside of the guide shell 3. The inside of the guide shell 3 is a connector core 4. A limiting ring groove 5 is formed on the inner side of the connector core 4. The connector 1 is connected to a connecting core 9 fixedly connected to one end of the connector base 6 through the connector core 4. A connecting shell 8 is formed on the outside of the connecting core 9. A sealing mechanism 7 is connected inside the connecting shell 8 through a fixing ring 10. Both ends of the fixing ring 10 are provided with disassembly holes 11. The sealing mechanism 7 includes a sealing cover 71. A baffle 72 is installed at one end of the sealing cover 71. The connecting shell 8 includes a shell 81. A positioning ring groove 82 is formed on the inner side of one end of the shell 81.

[0030] As a further implementation of this solution, the inner side of the connecting shell 2 is provided with an internal thread, and the outer side of the connecting shell 8 is provided with a threaded groove. The connecting shell 2 and the connecting shell 8 are spirally connected. Through the above settings, the overall stability of the coaxial connector connection can be guaranteed, and the problem of loosening caused by collision at the coaxial connection can be prevented.

[0031] As a further implementation of this solution, the outer edge of the guide shell 3 away from the plug 1 is arc-shaped, and the inner edge of the connecting shell 8 away from the plug 6 is arc-shaped. The guide shell 3 and the connecting shell 8 are compatible. Through the above settings, the smoothness of the connection between the guide shell 3 and the connecting shell 8 can be improved.

[0032] As a further implementation of this solution, the sealing cover 71 is tapered, and the sealing cover 71 has an opening at the location where the baffle 72 is installed. Through the above-mentioned arrangement, the sealing cover 71 can effectively prevent the connection between the plug core 4 and the connecting core 9 from being affected.

[0033] As a further implementation of this solution, the side of the sealing cover 71 away from the baffle 72 is installed inside the positioning ring groove 82 by a fixing ring 10. The fixing ring 10 has a notch in the middle and two disassembly holes 11. The opening edge of the disassembly hole 11 is arc-shaped. With the above settings, it is convenient to replace the sealing cover 71 in the future.

[0034] As a further implementation of this solution, the connector 1, connecting shell 2, guide shell 3, connector core 4, connector socket 6, and connecting core 9 are on the same axis. Through the above arrangement, the stability of the connection between connector 1 and connector socket 6 can be further improved.

[0035] Workflow: During the assembly and use of the anti-collision RF coaxial connector, the operator controls the connector 1 to move towards the socket 6. During this movement, the guide shell 3 is inserted into the connecting shell 8, and then the connecting shell 2 is rotated to connect with the connecting shell 8, thus achieving a fixed connection between the connector 1 and the socket 6. During the connection process, the connector core 4 passes through the sealing cover 71 and pushes open the retainer 72 to connect with the connecting core 9. After the connection is completed, signal transmission can be performed. When the connector 1 and the socket 6 are separated later, the connector core 4 will pull the sealing cover 71 out of the connecting shell 8 through the set limiting ring groove 5, thereby preventing dust from entering the socket 6 during the separation process and causing poor contact after reconnection. At the same time, when the sealing cover 71 is damaged later, it can be replaced by removing the fixing ring 10, which effectively improves the convenience and cost of later maintenance.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
