Problems solved by technology

However, since only one card can be prepared at a time, its production efficiency is relatively low
[0005] In addition, in view of the fact that the existing card base production equipment is usually designed based on the production of one small card base in one large card base, none of the existing production concepts is based on the simultaneous production of nine small card bases in one large card base

Embodiment Construction

[0025] see figure 2 , the large card base 100 includes a card base body 110 on which 9 small card bases 120 are evenly arranged. The large card base 100 is equivalent in size and shape to a conventional large card base comprising only a single small card base. On the back of the large card base 100, a stamping groove 130 for easy punching is pre-set around each small card base 120, so as to facilitate the processing of a single small card base 120, and each small card base 120 has a Standard size and shape for the SIM card slot.

[0026] see image 3 , as can be seen from the cross-sectional view at the middle of the large card base 100, along the longitudinal direction of the large card base 100, there are three small card bases 120 of the same specification and the chip slots thereon.

[0027] see Figure 4 and Figure 7 , The large card base 100 is molded at one time by injection molding process, and three chip grooves are evenly formed on the large card base 100 alon...

Abstract

The invention relates to a card base of a nine-core smart card, belonging to the technical field of smart cards. In particular, nine small card bases are uniformly distributed on a large card base of a standard size; the entire card base is molded with an injection molding process; and a card groove is formed on each small card base, comprises a middle groove and a surface groove, and is molded at one time with an injection molding process, so that a chip can be attached to the inside of the chip groove. The card base has the advantages of saving materials, reducing waste, greatly increasing the production efficiency and saving cost, and can be applied to the smart card fields of mobile phone SIM (Subscriber Identity Module) cards, bank cards, restaurant cards, public transport cards, water and electricity cards, gas cards, and the like.

Description

technical field [0001] The invention relates to a card base of a smart card, in particular to a card base of a mobile phone SIM card. Background technique [0002] With the advancement of science and technology and the development of social economy, smart cards have been more and more widely used in every corner of life, such as mobile phone SIM cards, bank cards, restaurant cards, bus cards, water and electricity cards, gas cards, etc. Traditional smart cards on the market, such as mobile phone SIM cards, have similar figure 1 the shape shown. The small card base 12 of the big card base 10 is positioned on the card basic body 11, and the periphery of the small card base 12 is connected with the card basic body 11 by a broken line 14, and a chip is glued on the small card base 12. The card base body 11 and the small card base 12 are made of the same material, and are usually made of three layers of materials, which are divided into a surface layer, a middle layer and a bot...
