Plug assembling method and structure of electronic seal

Abstract

The invention discloses a plug assembling method and a structure of an electronic seal. The assembling method includes the steps that A, a plug body is manufactured, wherein the plug body is provided with a rod body with the bottom end capable of being inserted into a plug base, a containing hole which penetrates through the bottom end of the rod body and a first buckling part which is arranged inside the containing hole; B, a circuit unit with a control loop is manufactured, wherein the control loop is composed of a circuit wire harness, a lower contact point and an RFID chip; C, an inner rod with a second buckling part is manufactured, the circuit unit is mounted on the inner rod, the mounted circuit unit and the inner rod are inserted into the containing hole from the bottom end of the rod body, the first buckling part and the second buckling part are combined to position the inner rod, and when the rod body is inserted into the plug base and can not break away, the control loop of the circuit unit is started by the lower contact point. By the adoption of the method, an assembled plug can directly force the inner rod and the circuit unit to be pulled out from the bottom end of the containing hole when the plug can not be well tested, a novel inner rod and circuit unit set can replace the original one, and the displacement method is extremely convenient.

Description

technical field [0001] The invention relates to a plug assembly method and structure of an electronic seal. Background technique [0002] China Taiwan Patent Application No. 099142305 discloses a kind of electronic seal, the concrete structure of its plug 10 is as follows figure 1 and figure 2 shown, including: [0003] A bolt body 11, which has a shaft 111, a cap head 112 extending radially outward at the top of the shaft 111, a cavity 113 axially penetrating through the shaft 111 and the cap head 112, and a radially outwardly expanding cap head 112. A countersunk hole 113A on the top edge of the cavity 113, a set of collar 114 fitted on the outer periphery of the shaft 111; [0004] A flexible circuit board 12, which has a control loop, the control loop is composed of a printed circuit 121, a lower contact 122, and an RFID chip 123; [0005] An inner rod 13, the circuit board 12 is mounted on the inner rod 13, the inner rod 13 is inserted into the cavity 113 from the ...

AI Technical Summary

Problems solved by technology

[0011] 2. When it is found that the circuit board 12 is defective and fails, and a new set of circuit boards 12 must be replaced, it must go through the procedures of dismantling the waterproof case → removing the upper cover in sequence. After replacing the new circuit board 12, it must be replaced. Thermoforming a waterproof cover 15 again. This replacement method not only accumulates man-hours due to the increase in the number of actions, but also makes it difficult to increase economic benefits. This is where the current processing technology cannot break through

[0012] In view of the problem of high defect rate of RFID chips or circuit boards caused by conventional plug assembly, and the disadvantage of time-consuming and labor-intensive replacement of circuit boards, so that the cost of plugs cannot be further reduced. Continuously conceive, create and research, and develop this invention
