Abstract

The invention relates to a two-layer mobile phone card holder which comprises an iron shell, an upper-layer terminal, an upper-layer plastic body, a lower-layer terminal, a lower-layer plastic body and a PCB. The upper-layer plastic body is provided with a hole corresponding to the upper-layer terminal. The lower-layer plastic body is provided with a hole corresponding to the lower-layer terminal. The lower-layer terminal, the lower-layer plastic body, the upper-layer terminal, the upper-layer plastic body and the iron shell are arranged in sequence from bottom to top to form a whole. An upper-layer SIM card containing space is defined by the iron shell and the upper-layer plastic body. A lower-layer SIM card containing space is defined by the lower-layer plastic body and the upper-layer terminal. The PCB is of a U-shaped structure. The lower-layer terminal is contained in the middle of the PCB and connected with corresponding contacts at the two ends of the PCB through terminal pins. The height of the two-layer mobile phone card holder is 1.65 mm. By the adoption of the design, the function that two SIM cards can be inserted into one mobile phone card holder is achieved, the lower-layer terminal and the like are skillfully arranged in the middle of the U-shaped structure due to the U-shaped structure of the PCB, the occupation space of the mobile phone card holder is saved, and the two-layer mobile phone card holder has the advantages of being simple in structure, stable and reliable and saving space.

Description

A kind of double-layer mobile phone card holder

Technical field

The present invention relates to mobile communication technology field, particularly relate to a kind of double-layer mobile phone card holder.

Background technology

Along with the development of science and technology, mobile phone has become an indispensable part in the modern life.For realizing the function of mobile phone, usually need in cell phone system, use SIM card (Subscriber Identity Model, subscriber identification module).SIM card has multiple bare spot, and it can be electrically connected with the terminal be positioned on the SIM card deck of interior of mobile phone, thus realizes the functions such as call, storage information.

Due to life or requirements of one's work, people often have multiple number, and this just requires that mobile phone can insert multiple SIM card, but pursues the frivolous epoch at mobile phone, and interior of mobile phone space seems precious.Therefore study a kind of structure simple, reliable and stable, two SIM cards can be inserted simultaneously and save space-efficient mobile phone card seat and seem particularly important.

Summary of the invention

The technical problem to be solved in the present invention be design a kind of structure simple, reliable and stable, two SIM cards can be inserted simultaneously and save space-efficient mobile phone card seat.

For solving the problems of the technologies described above, double-layer mobile phone card holder of the present invention comprises iron-clad, upper strata terminal, upper strata plastic body, lower floor's terminal, lower floor's plastic body and pcb board.Upper strata plastic body is provided with the hole corresponding with upper strata terminal, lower floor's plastic body is provided with the hole corresponding with lower floor terminal, lower floor's terminal, lower floor's plastic body, upper strata terminal, upper strata plastic body and iron-clad arrange formation entirety successively from bottom to up, iron-clad and upper strata plastic body limit upper strata SIM card spatial accommodation, and lower floor's plastic body and upper strata terminal limit lower floor's SIM card spatial accommodation.Pcb board is U-shaped structure, and opening is lower floor SIM plug-and-pull port, and lower floor's terminal is placed in pcb board centre and is connected by the contact that terminal pins is corresponding to pcb board two ends.

Further, the bottom of the U-shaped structure of pcb board is provided with circular groove and forms hand position, convenient taking-up lower floor SIM card.

Further, the equal bending of head of upper strata terminal and lower floor's terminal, this is a kind of anti-PIN structural of bursting, and draw when empty calorie can be prevented to insert and turn over shell fragment, the relatively common deck of coefficient of safety is higher.

Further, upper strata terminal and lower floor's terminal can be and the terminal corresponding to SIM card, Micro-SIM card or Nano SIM card.

Further, the plug orientation of upper strata SIM card is vertical with the plug orientation of lower floor's SIM card, i.e. can be that upper strata is horizontal insert the SIM of levels arrangement, and lower floor is perpendicular to insert, and also can be that upper strata is perpendicular inserts, and lower floor is horizontal to insert.

Further, the height of this double-layer mobile phone card holder is 1.65mm.Such height saves the inner space of mobile phone greatly.

Beneficial effect of the present invention: after adopting such design, the function that a mobile phone card seat inserts two SIM is achieved by bilevel method, and levels is all provided with anti-PIN structural of bursting, draw when empty calorie can be prevented to insert and turn over shell fragment, the relatively common deck of coefficient of safety is higher, and dexterously lower floor's terminal etc. can be placed in the centre of U-shaped structure after pcb board is arranged to U-shaped structure, save mobile phone card seat further taken up space, have simple, the reliable and stable and joint space-efficient advantage of structure.

Accompanying drawing explanation

Below in conjunction with accompanying drawing the specific embodiment of the present invention done and illustrate further.

Fig. 1 is the explosive view of double-layer mobile phone card holder of the present invention;

Fig. 2 is the vertical view of double-layer mobile phone card holder of the present invention;

Fig. 3 is the bending structure figure of double-layer mobile phone card holder upper strata terminal of the present invention and lower floor's terminal.

Embodiment

Composition graphs 1, Fig. 2 and Fig. 3, double-layer mobile phone card holder of the present invention comprises iron-clad 1, upper strata terminal 2, upper strata plastic body 3, lower floor's terminal 4, lower floor's plastic body 5 and pcb board 6.Upper strata plastic body 3 is provided with the hole corresponding with upper strata terminal 2, lower floor's plastic body 5 is provided with the hole corresponding with lower floor terminal 4, lower floor's terminal 4, lower floor's plastic body 5, upper strata terminal 2, upper strata plastic body 3 and iron-clad 1 arrange formation entirety successively from bottom to up, iron-clad 1 and upper strata plastic body 3 limit upper strata SIM card spatial accommodation, and lower floor's plastic body 5 and upper strata terminal 2 limit lower floor's SIM card spatial accommodation.Pcb board 6 is U-shaped structure, and opening is lower floor's SIM card plug-and-pull port, and lower floor's terminal 4 is placed in pcb board 6 centre and is connected by the contact 601 that terminal pins 401 is corresponding to pcb board 6 two ends.
