DETAILED DESCRIPTION

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figure 1-4As shown, the utility model proposes an anti-theft bidirectional thyristor, comprising a bidirectional thyristor body 1 and a security chip box 2 installed with a security chip, the security chip box 2 is fixed on the outside of the bidirectional thyristor body 1, an execution slot 11 is opened in the bidirectional thyristor body 1, an execution board 3 is installed in the execution slot 11, a group of wiring terminals 12 are fixed to the upper side wall of the execution slot 11, a mounting terminal 4 is fixed at the bottom of the bidirectional thyristor body 1 and at a position corresponding to the wiring terminal 12, a telescopic component 5 for driving the execution board 3 to telescope is arranged in the execution slot 11 and between the mounting terminal 4 and the wiring terminal 12, a data connector 21 is plugged into the outer surface of the security chip box 2, and a connector connecting piece 31 is fixed on the execution board 3 and at a position corresponding to the wiring terminal 12.

[0022] The telescopic assembly 5 includes an electromagnet 51 and a reset spring 52. The electromagnet 51 is fixed to the upper side wall of the execution slot 11 and is located between the adjacent wiring terminals 12. The reset spring 52 is fixed between the execution plate 3 and the bottom of the execution slot 11 and its position corresponds to the electromagnet 51. A metal sheet 53 is provided at the upper end of the execution plate 3 and at a position corresponding to the electromagnet 51. A rubber pad 55 is fixed to the bottom of the metal sheet 53. The bottom of the rubber pad 55 is fixed to the execution plate 3. An insulating block 54 is fixed to the connection between the reset spring 52 and the execution plate 3. The bottom of the execution plate 3 and the mounting terminal 4 are opposite to each other. A fixing sleeve 57 is fixed in the same position, the upper end of the terminal 12 is located in the execution groove 11 and is fixed with a fixing column 56, the upper end of the fixing column 56 is slidably connected in the fixing sleeve 57, the outer side of the fixing column 56 is in contact with the inner wall of the fixing sleeve 57, and both are made of conductive metal materials. When the electromagnet 51 is energized, a magnetic field can be generated to adsorb the metal sheet 53, and finally the execution plate 3 can be moved upward under the condition of stretching the reset spring 52, and finally the execution plate 3 can be docked with the terminal 12, so that a passage is formed between the installation terminal 4 and the terminal 12.

[0023] In this embodiment, the entire device is first connected to an external power supply, and the mounting terminal 4 on the bidirectional thyristor body 1 is connected to a designated circuit board. At this time, the electromagnet 51 can be powered on and controlled by the security chip in the security chip box 2 after receiving an external control signal or password input. At this time, when the electromagnet 51 is energized, a magnetic field can be generated to adsorb the metal sheet 53, and finally the actuator plate 3 can be moved upward by stretching the reset spring 52. Finally, the actuator plate 3 can be docked with the wiring terminal 12, so that the mounting terminal 4 and the wiring terminal 12 form a passage to ensure the normal operation of the bidirectional thyristor body 1. On the contrary, when the control signal or password input is not received, the reset spring 52 is used to pull the actuator plate 3 to disconnect the upper end of the actuator plate 3 from the wiring terminal 12. At this time, the bidirectional thyristor body 1 cannot work, thereby avoiding theft or illegal use of electrical equipment.
