Problems solved by technology

[0003] However, some thieves found that as long as figure 2 As shown, use a grinder 95 to grind the cap head 911 of the plug 91 to a diameter smaller than the bolt hole 931 of the door bolt 93, so as not to damage the internal circuit operation of the electronic seal 90, and then pull the plug 91 out of the bolt hole 931 , and then, the container door can be opened to steal. After the theft is completed, the plug 91 is only inserted into the bolt hole 931 in reverse, so that the bolt seat 92 is buckled upside down on the door bolt 93, and the electronic seal 90 can be activated. It can operate normally as before, causing the customs to identify the host and fail to alarm

Embodiment Construction

[0047] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0048] Please see Figure 3 to Figure 8 , the present invention is an electronic seal composed of a bolt A and a bolt seat B. The bolt A can be inserted into the bolt seat B from top to bottom to lock the door bolt C to lock the container door. The bolt seat B, The door bolt C is an existing existing technology, so the present invention will not go into details. The feature of the present invention is the plug A, and the plug A at least includes:

[0049] A conductive bolt body 10, the bolt body 10 has a shaft 11, a cap head 12 extending radially outward from the top of the shaft 11, and a cavity 13 axially penetrating the shaft 11 and the cap head 12 1. A set of collar 14 that fits on the outer circumference of the shaft 11 and abuts against the bottom end of the cap head 12, the diameter of the cap head 12 i...

Abstract

Tamper-proof electronic seal. The present invention is composed of a plug and a plug seat. The plug body of the plug has a shaft, a cap head expanding outward on the top of the shaft, a hole running through the upper and lower sides, and a first engaging hole located at the bottom edge of the shaft. configuration. The top edge of the container hole is expanded outward with a countersunk hole with an inner diameter not less than the bolt hole of the door bolt. The hole is equipped with a circuit board, and the circuit board has a circuit wiring, a lower contact connected to the circuit wiring, an upper contact, an RFID chip installed on the circuit wiring, and a third larger than the hole is installed below the hole. The buckle, and an upper elastic piece abutted against the bottom of the countersunk hole, and an upper elastic piece abutted against the bottom surface of the upper cover are installed on the top to elastically suspend the circuit board in the cavity, and to control that the upper contact cannot be in contact with the upper cover. For electrical connection, however, when the first engagement configuration is inserted into the bolt seat and cannot be disengaged, the lower contact can provide an electrical connection between the RFID chip and the internal antenna of the bolt seat, and the upper contact can be electrically connected to the upper cover, so that the bolt body forms An external antenna for the RFID chip.

Description

technical field [0001] The present invention provides a tamper-proof electronic seal, more specifically, especially a special technology that thieves can cut off the internal circuit when grinding the diameter of the cap head of the plug. Background technique [0002] figure 1 Disclosed is a traditional electronic seal 90 composed of a plug 91 and a plug seat 92. The plug 91 is provided with an RFID chip, and the plug seat 92 is provided with an internal antenna. The door bolt 93 can lock the container door 94, and the RFID chip is electrically connected to the internal antenna of the bolt seat 92, and the plug 91 forms an external antenna. At this time, the customs only needs to use an identification host to emit an electromagnetic wave for the external antenna to receive, and the RFID chip can convert the energy provided by the electromagnetic wave into a voltage, and use the voltage to modulate the identifier stored in the RFID chip into an electromagnetic wave. Then it...
