Radio Frequency (RF) is an abbreviation for Radio Frequency, which refers to an electromagnetic Frequency that can radiate into space, ranging from 300KHz to 300 GHz. The short term Radio Frequency (RF) is radio frequency current, which is a short term for high frequency Alternating Current (AC) variable electromagnetic wave. Alternating current that changes less than 1000 times per second is called low frequency current, and alternating current that changes more than 10000 times per second is called high frequency current, and radio frequency is such a high frequency current. High frequency (greater than 10K); the radio frequency (300K-300G) is a higher frequency band of high frequency; the microwave band (300M-300G) is again the higher frequency band of radio frequencies. In the theory of electronics, current flows through a conductor, and a magnetic field is formed around the conductor; an alternating current passes through a conductor, around which an alternating electromagnetic field, called an electromagnetic wave, is formed. When the frequency of the electromagnetic waves is lower than 100kHz, the electromagnetic waves can be absorbed by the earth surface and cannot form effective transmission, but when the frequency of the electromagnetic waves is higher than 100kHz, the electromagnetic waves can be transmitted in the air and reflected by an ionosphere at the outer edge of the atmosphere to form long-distance transmission capability, and the high-frequency electromagnetic waves with the long-distance transmission capability are called radio frequency; radio frequency technology is widely used in the field of wireless communications.

In this embodiment, lock facing slip 5 is connected with the cooperation of lock body 4 and makes the lock seal device be in the lock state of sealing, and lock facing slip 5 makes the lock seal device be in the unblock state with the separation of lock body 4, because of the barb switches on piece 3 and has the elasticity function, and circuit access end contact in 5 with the lock facing slip or disconnection realizes that lock seal circuit or other circuits switch on and break off, and other circuits can be radio frequency circuit, or non-radio frequency circuit. Referring to fig. 7, the barb leading-through member 3 has an elastic function, because one end of the barb leading-through member 3, which is used for being connected with an external connecting element, is connected with the mounting member through an elastic structure, which may be a spring, such as a compression spring 8. It can be understood that the barb leading-through 3 may have an elastic function, such as a spring sheet. In the process that the locking device forms the locking state, one end of the locking seal 5 slides forwards to the position where the first circuit of the locking seal is electrically connected with the first circuit of the lock body along and presses the stressed inclined surface 31 of the at least one barb conducting piece 3 or the other end of the barb conducting piece 3. In the process, the barb conducting piece 3 is bounced under the oblique acting force applied by the locking seal 5, so that the barb conducting piece 3 has elastic potential energy or the elastic potential energy is increased; when the lock seal 5 and the barb lead-through piece 3 are separated, the oblique acting force is removed to enable the barb lead-through piece 3 to rebound to the original position under the action of elastic potential energy or rebound to the original position to abut against an object blocking the rebound, if a concave groove appears at the part where the lock seal 5 and the barb lead-through piece 3 slide relatively, the barb lead-through piece 3 and the sliding end of the part further rebound, and if the groove is a through hole, the end can pass through the through hole to the original position under the action of the elastic force. The relative movement between the lock seal 5 and the barb leading part 3 may be a linear movement or a curved movement, such as an S-shaped curved movement.

The oblique acting force is a force that acts on the force-receiving inclined surface 31 of the barb leading piece 3 and makes it possible to bounce up from the original position. After the barb leads to 3 bounces, lock facing slip 5 can slide along atress inclined plane 31 forward, and after sliding atress inclined plane 31, the barb leads to 3 one end or the surface that the lock facing slip 5 was held in the top of one end more than one end of piece. The front of the insertion end of the lock facing slip 5 is also an inclined plane, so that the lock facing slip 5 can conveniently slide into the insertion space of the lock sealing device, and the resistance is reduced.

In order to ensure that the lock facing slip 5 and the barb conducting piece 3 are mutually matched and stable, the lock facing slip 5 and at least one barb conducting piece 3 are locked and connected at a concave-convex clamping position, the two can be locked at the concave-convex clamping position, the convex part can automatically go deep into the concave part through the elastic function of the barb conducting piece 3, the convex end of the barb conducting piece 3 can extend into the concave end of the lock facing slip 5 to form the clamping position for locking and connecting, the concave end of the barb conducting piece 3 and the convex end of the lock facing slip 5 can also form the clamping position for locking and connecting, and the convex part of the barb conducting piece 3 can be the barb 30.

An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas. The same antenna is the same as the basic characteristic parameter for transmission or reception. At present, the antenna is more and more widely applied, the anti-interference requirement is more and more strict, and the design types are diversified.
