Description

Technical Field

[0001] The present invention belongs to the technical field of radio frequency connectors, and specifically relates to a highly protective waterproof radio frequency connector. Background Art

[0002] RF coaxial connectors are usually considered to be a component installed on cables or instruments. As a component for electrical connection or separation of transmission lines, it belongs to mechatronics products. Simply put, it mainly plays a bridging role.

[0003] Through the joint efforts of experts from various countries, RF coaxial connectors have formed an independent and complete professional system and become an important part of the connector family. They are an indispensable key component of the coaxial transmission system. The RF coaxial connector development technology in the United States, Britain, France and other countries is in a leading position. Its design, production, testing and use technologies have been integrated and perfected. Not only has a complete standard system been formed, but also the raw materials, transmission materials, testing systems, assembly tools, etc. have been standardized and professionalized and mass-produced.

[0004] Most of the existing right-angle bending type RF connectors are assembled vertically through a right-angle connecting shell. The inside of the right-angle connecting shell is connected by a conductor, and the outside of the right-angle connecting shell is connected by a conductive shell and a plug-in shell, thereby realizing the installation of the right-angle connector.

[0005] However, due to the assembled connector housing, its waterproof performance is greatly reduced compared to the one-piece housing, and the connection gap between the housings will easily penetrate condensed water. Therefore, the usual practice is to set a sealing groove at the end face of the connection, and then set a sealing rubber ring in the sealing groove to achieve sealing of the connection surface.

[0006] However, this form not only requires an annular groove to be opened on the surface of the shell, but also because it only has one compression-type sealing ring, it is very easy to cause water seepage during long-term use. In addition, due to the limited width of the end face of the shell itself, it is impossible to set multiple layers of sealing rings. Utility Model Content

[0007] In order to solve the above problems, this paper proposes a highly protective waterproof RF connector, the RF connector includes a conductive shell, a plug-in shell and a right-angle connecting shell, the outer side of the right-angle connecting shell is vertically plugged into the conductive shell, the outer side of the end face of the bracket connecting shell is sleeved with a plug-in shell, the upper and lower sides of the right-angle connecting shell are penetrated with a vertical cavity, one end of the right-angle connecting shell is horizontally provided with a horizontal cavity, the horizontal cavity and the vertical cavity are vertically connected and passed through each other, a conductive shell is plugged into one end of the vertical cavity, and a sealing groove is provided at the rounded corner of the plug-in end of the conductive shell A sealing groove is provided at the rounded corner of the plug-in end of the right-angle connecting shell on the outside of the transverse cavity. The sealing groove is in the shape of a vertical angle annular groove. A sealing rubber block is embedded in the inside of the sealing groove. A pressing convex edge is provided at the connection between the outer side of the sealing rubber block and the inner side of the right-angle connecting shell or the plug-in shell. The conductive shell, the plug-in shell and the right-angle connecting shell are connected and fixed by using the sealing rubber block and the sealing rubber block, so that the shell connection can be ensured to be stable, and the mutual cooperation of the sealing rubber block and the pressing convex edge can press the sealing rubber block down and seal it, thereby further improving the waterproof performance of the shell.

[0008] The right-angle connecting shell is in the shape of a cylindrical shell, and a vertical cavity is provided on the outer arc surface of one end of the right-angle connecting shell, and a transverse cavity is provided on the other end face of the right-angle connecting shell. A conductive shell is plugged into one end of the vertical cavity, and a sealing gland is plugged into the other end of the vertical cavity. A plug-in shell is provided on the outer side of the transverse cavity. The right-angle connecting shell, the conductive shell and the plug-in shell are connected by sealing adhesive. The vertical cavity is in the shape of a cylindrical cavity, and the ports of the vertical cavity are all stepped circular ports. A gland sealing ring is provided between one end of the vertical cavity and the sealing gland, and a gland insulator is provided on the bottom surface of the sealing gland. A clamping convex edge is provided on the inner bottom surface and side surface of the other end of the vertical cavity. The transverse cavity is in the shape of a cylindrical blind hole cavity, and a sleeve step is provided on the outer side of the end face of the transverse cavity.

[0009] The thickness of the sealing groove is the same as that of the sealing block, and the shape of the sealing groove is the same as that of the clamping ridge. The thickness of the clamping ridge is less than half of the thickness of the sealing groove. The sealing block can achieve a large range of sealing at the step corner, thereby ensuring the assembly effect after the connector is installed, and the clamping ridge can also assist in the locking of the sealing block to ensure the installation strength.

[0010] Beneficial effects:

[0011] The conductive shell, the plug-in shell and the right-angle connecting shell are connected and fixed by using a sealing block and a sealing glue, so that the shell connection can be ensured to be stable, and the mutual cooperation between the sealing block and the pressing convex edge can press the sealing block down to seal, thereby further improving the waterproof performance of the shell.
