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, the first lock body 41 and the second lock body 42 are cooperatively connected to enable the locking device to be in a locking state, the first lock body 41 and the second lock body 42 are separated to enable the locking device to be in an unlocking state, the barb conducting piece 3 has an elastic function, and is in contact with or disconnected from the second circuit access end to achieve the connection and disconnection of the locking circuit or other circuits, and the other circuits may be radio frequency circuits or non-radio frequency circuits. The barb switches on piece 3 and has the elasticity function because the barb switches on the one end that piece 3 is used for being connected with external connecting piece and passes through elastic construction and installed part and be connected, and elastic construction can be the spring, like pressure spring 8 etc.. It can be understood that the barb leading-through 3 may have an elastic function, such as a spring sheet. During the process of forming the locking state of the locking device, the connecting section 43 slides forward along and presses the force-bearing inclined surface 31 of at least one barb conducting member 3 or the other end of one barb conducting member 3 to a position where the first circuit is electrically connected with the second circuit. In the process, the barb conducting piece 3 is bounced by the oblique acting force applied by the connecting section 43, so that the barb conducting piece 3 has elastic potential energy or the elastic potential energy is increased; when the connecting section 43 is separated from the barb conducting piece 3, the oblique acting force is removed to enable the barb conducting piece 3 to rebound to the original position under the action of elastic potential energy or rebound to an object resisting and blocking the rebound towards the original position, if a concave groove appears at the part where the connecting section 43 and the barb conducting piece 3 slide relatively, the barb conducting 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 connecting section 43 and the barb leading part 3 can 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.

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.
