Problems solved by technology

[0003] When most passengers use bus IC cards, they usually carry them with them and put them in their trouser pockets or wallets for easy use; however, due to their small size and thin thickness, bus IC cards are easy to lose or be bent when carrying them. , which in turn causes the bus IC card shell to break and the chip in the card to be damaged

Embodiment 1

[0024] Such as figure 1 As shown, this embodiment includes the following steps:

[0025] (A) forming an upper shell 1 and a lower shell 2 capable of engaging with each other by injection molding in a mold;

[0026] (B) Install filler 5 in lower case 2, and place chip 3 at the center of lower case 2;

[0027] (C) The upper casing 1 and the lower casing 2 are connected and matched by the rubber block 4, and then the upper casing 1 and the lower casing 2 are bonded and sealed by an adhesive.

[0028] In the above steps, the upper casing 1 and the lower casing 2 are connected to each other through rubber blocks 4 to form a closed cavity, and a chip 3 is fixed in the cavity, and a filler 5 is provided between the chip 3 and the cavity, Two elastic connecting portions 6 are provided on the outer walls of the upper casing 1 and the lower casing 2 respectively, and the width of the connecting portions 6 is 1 / 4 of the total width of the upper casing 1 . The work of the present inven...

Embodiment 2

[0031] Such as figure 1 As shown, in this embodiment, on the basis of Embodiment 1, the four connecting parts 6 are arranged symmetrically on the outer walls of the upper casing 1 and the lower casing 2 centering on the cavity. Four elastic connecting parts 6 are symmetrically distributed in pairs on the upper casing 1 and the lower casing 2. When the surface of the IC card is impacted by an external force, the elastic recovery of the connecting parts 6 can be superimposed to the maximum, and the direction is consistent with the direction of the external force. On the contrary, to the greatest extent offset the distortion caused by the external force acting on the card surface.

[0032] Preferably, the cross section of the connecting portion 6 is wavy. The connection portion 6 with a wavy cross section can generate a relatively large amount of deformation per unit area, which can further improve the buffer protection of the upper shell 1 and the lower shell 2 .

Abstract

The invention discloses a processing method of a high-strength smart bus card shell, which comprises the following steps: (A) forming an upper shell and a lower shell that can engage with each other by injection molding in a mold; (B) installing a filler in the lower shell and placing the chip at the center of the lower case; (C) connecting the upper case and the lower case through a rubber block, and then bonding and sealing the upper case and the lower case through an adhesive. When the IC card is about to be deformed by an external force perpendicular to the card surface or at a certain angle, two elastic connecting parts are respectively provided on the outer walls of the upper casing and the lower casing to deform along with the direction of the external force to slow down the external force The distortion caused to the card surface as a whole, at the same time, the rubber block located between the upper shell and the lower shell is compressed by force, and the auxiliary elastic connection part minimizes the twist force caused by the external force on the card surface during the recovery deformation process, and then Prevent the chip from being damaged due to excessive distortion of the IC card.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a processing method for a high-strength smart bus card casing. Background technique [0002] IC card refers to integrated circuit card. The bus card we generally use is a kind of IC card. Generally, common IC cards use radio frequency technology to communicate with IC card readers. There is a difference between IC cards and magnetic cards. The card stores information through the integrated circuit in the card, while the magnetic card records information through the magnetic force in the card. The cost of the IC card is generally higher than that of the magnetic card, but the confidentiality is better. The bus IC card is a kind of non-contact data card, it is through the chip integrated in the card through the inductance coil on the card (the inductance coil is also a coil made of copper wire) at both ends of the coil through various The function of the circuit makes the induc...
