The radio frequency base station comprises any one of the radio frequency connectors, and is used for transmitting or receiving high-frequency signals, and particularly comprises a signal transmitter, a signal receiver and a signal processor, wherein the signal transmitter and the signal receiver are connected through cables, the signal receiver and the signal processor are connected through cables, and according to the limitation of the length of the cables, the two sections of cables are connected through the radio frequency connectors, so that stable transmission of the signals is ensured.
In combination with the above embodiments, the application principle and the working process of the radio frequency connector provided by the embodiment of the invention are as follows:
when the connector is in operation, when two sections of cables are connected, one section of cable is connected with the male head 110 at the end part, the cable is communicated with the contact shaft 111 in the male head 110, the other section of cable is connected with the female head 120 at the end part, the cable is communicated with the contact groove 121 in the female head 120, and the contact shaft 111 on the male head 110 is gradually inserted into the contact groove 121 of the female head 120.
During the insertion of the contact shaft 111 on the male head 110 into the contact groove 121 of the female head 120, the mounting ring 210 on the male head 110 gradually enters the mounting groove 122 on the female head 120, and the locking block 241 on the locking ring 240 is aligned with the guide groove 123, so that the mounting ring 210 can enter the mounting groove 122. During the process that the mounting ring 210 enters the mounting groove 122, the first driving ring 220 is gradually driven by the driving wheel 280 to rotate, and during the process that the locking block 241 slides along the guiding groove 123, the locking ring 240 cannot rotate, so that the first force accumulating member 250 between the first driving ring 220 and the locking ring 240 is gradually accumulated. Since the guide groove 123 is communicated with the locking groove 124, as the mounting ring 210 is continuously inserted into the mounting groove 122, the side wall of the locking block 241 is gradually separated from the abutting guide groove 123, under the action of the first force storage member 250, the locking block 241 is separated from the abutting guide groove 123, and the first force storage member 250 pushes the locking ring 240 to rotate, so that the locking block 241 enters the locking groove 124.
When the locking block 241 enters the locking groove 124, the mounting ring 210 is continuously inserted into the locking groove 122, the second driving ring 230 starts to rotate by the driving ring, and the second driving ring 230 is aligned with the pushing groove 232 in the rotating process of the second driving ring 230, because in the initial state, one end of the driving rod 290 is fixedly connected to the pushing ring 430, the other end of the driving rod 290 is abutted to the sensing rod 410, a second spring 440 is arranged between the pushing ring 430 and the male head 110, the middle part of the driving rod 290 penetrates through the sliding groove 234 on the second driving ring 230, when the locking block 241 enters the locking groove 124, the locking ring 240 rotates, the driving rod 290 and the pushing groove 232 are progressively close, and when the second driving ring 230 rotates, the driving rod 290 is aligned with the pushing groove 232, the driving rod 290 rapidly moves along the sliding groove 234 under the action of the second spring 440, one end of the driving rod 290, which is close to the locking ring 240, enters the pushing groove 232, the mounting ring 210 is inserted into the bottom of the mounting groove 122, and according to the fact that the locking block 241 is in contact with the locking groove 124, the side wall 121 is in a rough surface, and the female head 111 is in contact with the male head 110, and the locking head 120 is prevented from contacting the locking groove 111, and the sliding with the locking groove 120, and the sliding surface is not in contact with the locking groove 120.
When the cable is pulled outdoors, the male head 110 and the female head 120 have a force away from each other, and if the male head 110 and the female head 120 want to be away from each other, the two driving wheels 280 need to rotate simultaneously, the two driving wheels 280 respectively drive the first driving ring 220 and the second driving ring 230 to rotate in opposite directions, at this time, the rotation of the first driving ring 220 gradually resets the first force accumulating member 250, the rotation of the second driving ring 230 drives the driving rod 290 to move synchronously, the driving rod 290 enters the second arc groove 243 from the pushing groove 232, the driving rod 290 gradually pushes the first end of the sensing rod 410, the first end of the sensing rod 410 is fixedly connected with the first sliding block 261 of the second force accumulating member 260, the second force accumulating member 260 gradually starts to accumulate force, at this time, the force of the second force accumulating member 260 is used to block the locking ring 240 from rotating, along with the pushing of the driving rod 290 to the first end of the sensing rod 410, the second end of the sensing rod 410 gradually abuts against the second section 422 of the limiting block 420, when the second end of the sensing rod 410 abuts against the second section 422 of the limiting block 420, the limiting block 420 is pushed by the sensing rod 410 to slide along the limiting groove 231, so that the first section 421 of the limiting block 420 no longer blocks the sliding of the second sliding block 262 along the second arc groove 243, and the second sliding block 262 connected to the second force accumulating member 260 abuts against the other limiting block 420 again after sliding along the second arc groove 243 for a certain distance, so that the mounting ring 210 slides outwards along the mounting groove 122 for a certain distance. Along with the cable is continuously pulled, the auxiliary block 330 on the locking block 241 gradually slides along the auxiliary groove 320, so that the male head 110 and the female head 120 are gradually separated, damage to the cable caused by the cable is prevented from being continuously pulled, and the service life of the cable is prolonged.
If the worker separates the male head 110 from the female head 120, the worker pulls the reset lever 520, the reset lever 520 drives the push ring 430 to move synchronously, and the driving lever 290 fixedly connected to the push ring 430 moves synchronously, so that the driving lever 290 is gradually separated from the push groove 232, and the second driving ring 230 and the locking ring 240 are separated from each other, at this time, in the process that the mounting ring 210 is separated from the mounting groove 122, the second force accumulating member 260 does not accumulate any more, so that the worker is convenient to separate the male head 110 from the female head 120.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
