As shown in fig. 3, at least two conductive pins 112 are disposed on the same side of the flexible transceiving component 110 in the width direction, and the ends of the at least two conductive pins 112 extend beyond the edge of the flexible transceiving component 110, and correspondingly, pin soldering holes 121 corresponding to the number of the conductive pins 112 are disposed on the printed circuit board 120. Thus, when it is desired to mount the flexible transceiver component 110 to the printed circuit board 120, the ends of the conductive pins 112 may be inserted into the pin soldering holes 121 and fixed to the printed circuit board 120 by soldering.
In addition, in order to match the wireless sensor with a plurality of different resonant frequencies, in the present embodiment, at least three conductive pins 112 are disposed on the same side of the flexible transceiver component 110. In practical applications, two of the conductive pins 112 may be determined according to the resonant frequency, and one end of the selected two conductive pins 112 is connected to the transceiving structure 111, and the other end is connected to a circuit structure in the printed circuit board 120, so as to form a loop adapted to the selected resonant frequency.
For example, as shown in fig. 3, the same side of the flexible transceiving component 110 is provided with 7 conductive pins 112, the 7 conductive pins 112 are all disposed on the same side of the flexible transceiving component 110 and are arranged in a mutually parallel manner, and correspondingly, as shown in fig. 4, the printed circuit board 120 is correspondingly provided with 7 pin soldering holes 121, and the 7 pin soldering holes 121 are arranged in a surrounding manner.

Therefore, according to the design requirement of the resonant frequency, two of the conductive pins 112 can be selected to be electrically connected with the transceiving structure 111, so that the transceiving structure 111 can match a plurality of different resonant frequencies. Of course, in other embodiments not shown, other numbers of conductive pins may be disposed on the flexible transceiver component.
It will be appreciated that in the uninstalled state, the transceiving structure 111 and the conductive pin 112 of the flexible transceiving component 110 are spaced apart from each other, and only after the design requirement of the resonant frequency is determined, the transceiving structure 111 and the selected conductive pin 112 are soldered to each other by means of soldering to form an electrical connection.
As one implementation, as shown in fig. 3, the conductive pin 112 is constructed by a metal material and may be formed in a long bar shape, one end of which away from the transceiving structure 111 extends beyond the edge of the flexible transceiving component 110, the other end of which is provided with a pin pad 114, and the transceiving structure 111 is provided with an antenna pad 115 at a position close to the pin pad 114. In the mounting process, after the resonant frequency is determined, the pin pads 114 of the two selected conductive pins 112 may be connected to the antenna pads 115 of the transceiver structure 111 by soldering or the like, and then the ends of all the conductive pins 112 are inserted and fixed to the pin soldering holes 121 of the printed circuit board 120 by soldering or the like, so as to fix the flexible transceiver component 110.

When the flexible transceiving component 110 needs to form a ring structure, the two sides of the flexible transceiving component 110 can be butted with each other through the butting holes 113, and the butting holes 113 on the two sides can be fixed with each other through welding or the like, so that the flexible transceiving component 110 can be stably formed into the ring structure, and the transceiving structure 111 can effectively receive and feed back wireless signals.
Illustratively, as shown in fig. 3, two sides of the flexible transceiver component 110 in the length direction are respectively provided with 5 docking holes 113, and in the installation process, the 5 docking holes 113 on the two sides can be sequentially placed and welded together, so as to avoid wrinkling at the side connection of the flexible transceiver component 110, improve the stability of the flexible transceiver component 110 after being formed into an annular structure, and ensure that the transceiver structure 111 can effectively receive and feed back wireless signals.

During the mounting process, the welding bosses 132 may be inserted into the boss welding holes 122 and fixed to the printed circuit board 120 by soldering or the like. It can be understood that the welding bosses 132 and the boss welding holes 122 are both annular, so that the connection seat 130 and the printed circuit board 120 can be reliably connected when the antenna 100 moves towards any direction, and the connection seat 130 and the printed circuit board 120 are prevented from being loosened in the moving process of the antenna 100 to affect the signal transmission effect.

In other embodiments, the other end of the core wire of the radio frequency cable can also be connected with a load cell according to the use requirement.
