Electronic seal improvement
First Claim
1. An electronic seal improvement, which at least comprises:
- a plug bolt, which is composed of a conductor and a circuit board;
wherein the conductor has an accommodation-hole with an opening facing downward and a top end thereof is closed by a top-cover;
wherein a first stuck-buckle is set in a lower portion of the conductor;
wherein the circuit board is mounted on the accommodation-hole and set with an RFID chip, and is further set with an upper contact point matching with the top-cover and a lower contact point protruding a bottom end of the accommodation-hole;
wherein the RFID chip is connected out to form a first pin and a second pin;
wherein a first far-field antenna circuit loop is formed by the RFID chip through the first pin, the upper contact point, the top-cover, and the conductor;
wherein the second pin is electrically connected with the lower contact point; and
a bolt seat set with an elastic device and an internal antenna, and an inserting-hole provided for inserting a lower portion of the conductor;
wherein the bolt seat is further set with a second stuck-buckle for positioning the first stuck-buckle, so as to control the elastic device to provide pre-pressure to the internal antenna to electrically connect with the lower contact point and to activate the RFID chip and the internal antenna to form a second far-field antenna circuit loop;
wherein the first far-field antenna circuit loop is synchronously activated, and the first far-field antenna circuit loop and the second far-field antenna circuit loop can be simultaneously cut off when the top-cover is disengaged.

Abstract
The present invention consists of a plug bolt and a bolt seat. The plug bolt comprises a conductor and a circuit board; the conductor has a first stuck-buckle, an accommodation-hole, and a top-cover; the circuit board is set with an RFID chip, an upper contact point, and a lower contact point. The RFID chip forms a first far-field antenna loop through the first pin, the upper contact point, the top-cover, and the conductor. The bolt seat is equipped with an elastic device, an internal antenna, an inserting-hole, and a second stuck-buckle, thereby controlling the elastic device to provide a pre-pressure to the internal antenna to electrically connect with the lower contact point. When the RFID chip is activated, the internal antenna forms a second far-field antenna loop and synchronously activate the first one; which the first and second far-field antenna loops can be cut-off when the top-cover is worn.
