Technical Field

[0001] The utility model relates to the technical field of radio frequency coaxial connectors, in particular to a dustproof radio frequency coaxial connector for data transmission. Background Art

[0002] RF coaxial connector is a connector used in RF communication and radio equipment. It has the structure and characteristics of coaxial cable and can provide high-frequency transmission and anti-interference performance. RF coaxial connector is mainly used to connect the signal transmission between coaxial cable and RF equipment. Its exterior consists of a cylindrical plug and socket. The plug can be inserted into the socket and rotated to lock to form a path for signal transmission. RF coaxial connector is a mechatronics product that mainly plays a bridging role. Its internal structure adopts a coaxial structure and the outer shell adopts a metal shielding design, which can effectively reduce electromagnetic radiation and anti-interference ability. RF coaxial connectors can transmit high-frequency signals from DC to GHz, so they are widely used in RF and microwave electronics.

[0003] During the use of the RF coaxial connector currently used for data transmission, there is a gap at the junction of the data transmitting cable and the RF coaxial connector. During long-term use, dust and other impurities can easily enter the interior of the RF coaxial connector through the gap, causing poor contact between the cable and the RF coaxial connector, thereby affecting data transmission. For this reason, we propose a dust-proof RF coaxial connector for data transmission. Utility Model Content

[0004] The utility model aims to provide a dustproof RF coaxial connector for data transmission, which has the advantages of being able to seal the junction between the data transmission cable and the RF coaxial connector, preventing dust from entering the interior of the RF coaxial connector through the gap, and also playing a waterproof role. At the same time, it can fix the cable to prevent the cable from falling off the RF coaxial connector. It solves the problem that during the use of the current RF coaxial connector for data transmission, there is a gap at the junction between the data transmission cable and the RF coaxial connector. During long-term use, impurities such as dust are easy to enter the interior of the RF coaxial connector through the gap, causing poor contact between the cable and the RF coaxial connector, thereby affecting data transmission.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dustproof RF coaxial connector for data transmission, comprising a tapered ring, a sleeve and a RF coaxial connector body, an external thread is provided on one side of the outer surface of the RF coaxial connector body, an internal thread is provided on one side of the inner wall of the sleeve, and the internal thread and the external thread are adapted to each other, a shrink ring is provided on the side of the sleeve away from the internal thread, a tapered rubber ring is fixedly installed inside the tapered ring, a plurality of incisions are equidistantly provided on the outer surface of the tapered ring in a circular array, and a fixing ring is welded on one side of the outer surface of the tapered ring.

[0008] Preferably, a linear groove is provided on the outer surface of the sleeve near the outer side of the threaded countersunk hole and on the outer surface of the RF coaxial connector body near the inner side of the socket. When the screw is turned to insert it into the socket, the two linear grooves are in the same straight line, which facilitates the accurate insertion of the screw into the socket.

[0010] Preferably, the inner diameter of the shrink ring increases along the axial direction, and when the sleeve is fixed to the RF coaxial connector body through internal and external threads, the shrink ring squeezes the conical ring, so that the incision on the conical ring becomes smaller, and at the same time the outer diameter of the conical ring shrinks, so that the conical rubber ring inside the conical ring is tightly wrapped around the outer surface of the cable, which plays a sealing and waterproof role while also fixing the cable.

[0011] Preferably, a sealing ring is fixedly installed inside the shrink ring near the outer side, and when the sleeve is fixed to the RF coaxial connector body through internal and external threads, the sealing ring contacts the outer surface of the tapered ring and is squeezed.

The other end of the connecting rod is inserted into the device port to complete the connection between the cable and the device.

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

[0015] 1. The utility model achieves the effect of sealing the junction between the data transmission cable and the radio frequency coaxial connector by arranging a radio frequency coaxial connector body, an external thread, a sleeve, an internal thread, a fixing ring, a tapered ring, a tapered rubber ring and a shrinking ring, so as to prevent dust from entering the interior of the radio frequency coaxial connector through the gap, and also play a waterproof role. At the same time, it plays a role in fixing the cable to prevent the cable from falling off the radio frequency coaxial connector. One end of the cable for data transmission is inserted into the interior of the radio frequency coaxial connector body, and the tapered ring and the sleeve are sleeved on the cable. The sleeve is rotated to be fixed to the radio frequency coaxial connector body through the internal thread and the external thread. When the sleeve is rotated, the shrinking ring squeezes the tapered ring, and the incision on the tapered ring becomes smaller. At the same time, the outer diameter of the tapered ring shrinks, so that the tapered rubber ring inside the tapered ring is tightly wrapped around the outer surface of the cable, which plays a sealing and waterproof role while also fixing the cable.

[0016] 2. The utility model achieves the effect of fixing and preventing the sleeve from loosening by arranging a threaded countersunk hole, a socket and a screw. By twisting the screw inside the threaded countersunk hole so that one end of the screw is inserted into the socket, the sleeve is fixed to prevent the sleeve from loosening.

[0017] 3. The utility model achieves the effect of facilitating the accurate insertion of the screw into the inside of the socket through the linear groove. When the screw is twisted to insert it into the inside of the socket, the two linear grooves are in the same straight line, which facilitates the accurate insertion of the screw into the socket.

[0018] 4. The utility model achieves the effect of preventing moisture and dust from entering between the sleeve and the RF coaxial connector body, thereby preventing the internal thread of the sleeve and the external thread of the RF coaxial connector body from rusting, through the sealing ring, the annular protrusion, the annular groove and the sealing ring. When the sleeve is fixed to the RF coaxial connector body through the internal thread and the external thread, the annular protrusion is inserted into the annular groove and squeezes the sealing ring, and the sealing ring contacts and is squeezed with the outer surface of the conical ring, so that the internal thread of the sleeve and the external thread of the RF coaxial connector body are sealed between the sleeve and the RF coaxial connector body, thus preventing water vapor and water from contacting the internal thread and the external thread, and preventing rusting.
