The figures are not drawn to scale, only to illustrate every aspect of the described embodiments, and do not limit the scope of the present invention.
    [0035] Referring to the attached Figs. 1-9, an electronic tag provided by the present invention includes a housing, an anti-theft cable 1, and a circuit board 2. An anti-theft alarm control circuit may be arranged on circuit board 2, when the circuit controller Anti-theft alarm control determines that the anti-theft cable has been cut, a sound alarm circuit or a light emission alarm circuit will be activated to generate an alarm. A frequency element 3 of the EAS anti-theft system may be configured in the housing.
    [0036] The anti-theft cable 1 includes two ends, and the two ends are provided with a first conductive contact 41 and a second conductive contact 42, respectively. The housing is provided with a first elastic conductor connection member 21 and a second elastic conductor connection member 22 to receive the first conductor contact 41 and the second conductor contact 42, respectively. The first elastic conductor connection member 21 and the second elastic conductor connection member 22 cooperate with the first conductor contact 41 and the second conductor contact 42, respectively, to conduct the circuits in the anti-theft cable 1 and the circuit board 2 for Form a return circuit. In first conductive contact 41 and second conductive contact 42 each include a conductive contact part 401 supported by the first and second elastic conductive connection members 21, 22, and a blocking part 402 configured to prevent the first conductive contact 41 and the second conductive contact 42 are removed from the housing in the locked state.
    [0037] The housing includes a first housing body 51 and a second housing body 52, which are connected together by screws or welded together by ultrasound to form a single integral unit.
    [0038] The housing is also provided with a first pinch member 61 corresponding to the first conductive contact 41. The first pinch member 61 cooperates with the first elastic conductor connection member 21 to cause a lower part of the first conductor contact 41 to come into tight contact. with the first elastic conductor connection member 21. An upper part of the first conductor contact 41 is clamped by a first clamp 611 (Fig. 5) of the first clamp member 61, so that the first conductor contact 41 cannot be removed at unless the first pinch member 61 breaks. Thus, the first conductive contact 41 is fixed in the housing and cannot be moved. The first pinch member 61 can be moved between a connection position and a replacement position and is normally held in the connection position (as shown in Figs. 4, 6 and 8) by a spring 63. The tag electronics also includes a structure 53 to move the first clamp member 61.
    [0039] The electronic tag is also provided with a second pinch member 62 corresponding to the second conductive contact 42. The second pinch member 62 can be moved between a locked position and a non-locked position. In the locked position, the second clamping member 62 cooperates with the second elastic conductor connection member 22 to cause a lower part of the second conductive contact 42 to come into close contact with the second elastic conductor connection member 22, and a part upper of the second conductive contact 42 is clamped by a second clamp 621 of the second clamp member 62. Thus, the second conductive contact 42 cannot be removed unless the second clamp member 62 breaks. In the non-blocking position, the second conductive contact 42 is released from the second clamp 621 of the second clamp member 62.
    [0040] The electronic tag also includes a locking structure. The blocking structure is capable of fixing / locking the second clamping member 62 in the blocking position. The electronic tag further includes an operating structure capable of moving the second pinch member 62 to the locked position. A spring is used to push the second pinch member 62 to move from the locked position to the non-locked position. Optionally, the operating structure is a pressure handle 620 disposed on the second pinch member 62.
    [0041] To simplify the structure, the first clamp member 61 and the second clamp member 62 are arranged side by side, so that the first clamp member 61 and the second clamp member 62 can share the same spring 63. In the state normal, the first pinch member 61 is held in the connection position by the spring 63 and the spring 63 pushes the second pinch member 62 to move from the locked position to the non-locked position. The spring 63 is disposed between the first member of grip 61 and the second grip member 62. The first grip member 61 includes a first positioning column 612 corresponding to the spring 63, and the second grip member 62 includes a second positioning column 622 corresponding to the spring 63.

The first pinch member 61 is located near the side wall of the housing. When the anti-theft cable needs to be replaced, the thin bar is inserted into the small hole 53 to push the first pinch member 61 from the connection position to the replacement position. In this case, the first conductive contact 41 is free of the first clamp 611.
    [0043] The first conductive contact 41 and the second conductive contact 42 may have the same structure, which includes a cylindrical body 400 and a head 403. The conductive contact part 401 is disposed at a front end of the cylindrical body 400. A rear end of the body cylindrical 400 forms a shoulder that acts as a locking part 402 to cooperate with the clamp member 61. The rear end of the cylindrical body 400 further includes a neck 404. The first clamp member 61 and the second clamp member 62 each include a large hole 601 configured to allow a conductive pin to pass through it and a pinch hole 602 to block the conductive pin. An upper part of the pinch hole 602 narrows to form a narrow hole and the first clip 611 and the second clip 621 are disposed on an end surface of the narrow hole. The large hole 601 communicates with the pinch hole 602. The narrow hole cooperates with the neck 404 which can enter the narrow hole from one side of the narrow hole.
    [0044] The electronic tag also includes a first positioning structure to prevent the first conductive contact from moving laterally to separate from the first clamp of the first clamp member and a second structure of
    [0045]
    [0046]
    [0047] positioning to prevent the second conductive contact from moving laterally to separate from the second clamp of the second clamp member. The pinch holes of the first and second pinch members correspond to the two positioning structures, respectively. Two ends of the anti-theft cable 1 are provided with positioning sleeves 7 corresponding to the positioning structures.

    [0049] The two positioning structures each include a first subunit 82 disposed in the first housing body 51 and a second subunit 81 arranged in the second housing body 52. The first subunit 82 and the second subunit 81 form a first positioning hole. and a second positioning hole. The disassembly of the housing can dismantle the two positioning holes and eliminate their positioning function.
    [0050] The first positioning hole corresponding to the anti-theft cable and the second positioning hole corresponding to the second conductor contact 42 are formed in the upper part of the housing. The two positioning structures are arranged in the first positioning hole 82 and in the second positioning hole 81, respectively. The first clamp member 61 and the second clamp member 62 are disposed below the first positioning hole 82 and the second positioning hole 81, respectively. The first elastic conductor connection member 21 and a first mounting base 210 thereof, and the second elastic conductor connection member 22 and a second mounting base 220 thereof, are disposed below the first pinch member 61 and the second member of grip 62, respectively. The circuit board 2 is arranged under the first and second mounting bases 210, 220.
    [0051] The blocking structure can adopt a commonly used block that can be unlocked after being attracted to magnets. The block includes a pin of block 91 and a spring 92. A magnet can attract block pin 91 to unlock the block. The spring 92 can push the block pin 91. When the second clamp member 62 remains in the locked position, and a lock hole 623 in the second clamp member 62 is aligned with the block pin 91, the spring 92 push block pin 91 into lock hole 623.
    [0052] The anti-theft cable 1 is a single core cable.
    [0053] The electronic tag also provides a switch 23 to control a protective status indicator lamp. The switch 23 is located in the path of the second pinch member 62 to the locked position. When the locked position is reached, the second clamp member 62 presses down the switch 23 to indicate the protective state of the second clamp member.
