Description

A kind of double-layer mobile phone card holder

Technical field

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

Background technology

With the development of science and technology, mobile phone turns into an indispensable part in the modern life.To realize the function of mobile phone, It is generally necessary to SIM cards are used in cell phone system（Subscriber Identity Model, subscriber identification module）.SIM cards Upper have multiple bare spots, and it can be electrically connected with the terminal on the SIM card decks of interior of mobile phone, so as to realize converse, The functions such as storage information.

Because life or requirements of one's work, people often possess multiple numbers, it is more that this requires that mobile phone is inserted into SIM card, but the frivolous epoch are pursued in mobile phone, interior of mobile phone space seems precious.Therefore study it is a kind of it is simple in construction, It is reliable and stable, two SIM cards can be inserted simultaneously and save space-efficient mobile phone card seat be particularly important.

The content of the invention

The technical problem to be solved in the present invention is that design one kind is simple in construction, reliable and stable, can insert two SIM cards simultaneously And save space-efficient mobile phone card seat.

In order to solve the above technical problems, the present invention double-layer mobile phone card holder include 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 hole corresponding with upper strata terminal, lower floor's plastic body be provided with Hole corresponding to lower floor's terminal, lower floor's terminal, lower floor's plastic body, upper strata terminal, upper strata plastic body and iron-clad are arranged from bottom to up successively Row form an entirety, and iron-clad and upper strata plastic body limit upper strata SIM card receiving space, and lower floor's plastic body limits with upper strata terminal Make lower floor's SIM card receiving space.Pcb board is U-shape structure, is open and is placed in for lower floor's SIM plug-and-pull ports, lower floor's terminal in pcb board Between and pass through terminal pins contact portion corresponding with pcb board both ends.

Further, the bottom of pcb board U-shape structure is provided with circular groove and forms hand position, convenient to take out lower floor's SIM card.

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

Further, upper strata terminal and lower floor's terminal can be and SIM card, Micro-SIM cards or Nano SIM cards institute Corresponding terminal.

Further, the plug orientation of upper strata SIM card is vertical with the plug orientation of lower floor SIM card, i.e. levels arrangements SIM, which can be that upper strata is horizontal, to be inserted, and the perpendicular slotting or upper strata of lower floor is perpendicular to insert, and lower floor is horizontal to insert.

Further, the height of the double-layer mobile phone card holder is 1.65mm.Such height greatlys save the inside of mobile phone Space.

Beneficial effects of the present invention：After such design, a Mobile phone card is realized by bilevel method Two SIM of seat insertion function, and levels are all provided with anti-routed PIN structural, can prevent to draw during empty calorie insertion and turn over shell fragment, The relatively common deck of safety coefficient is higher, and lower floor's terminal etc. dexterously can be placed in into U after pcb board is arranged into U-shape structure The centre of type structure, further save mobile phone card seat and taken up space, have simple in construction, reliable and stable and section space-efficient excellent Point.

Brief description of the drawings

The embodiment of the present invention is furtherd elucidate below in conjunction with the accompanying drawings.

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

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

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

Embodiment

With reference to Fig. 1, Fig. 2 and Fig. 3, double-layer mobile phone card holder of the invention include 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 and 2 corresponding hole of upper strata terminal, lower floor's plastic body 5 Provided with 4 corresponding hole of lower floor terminal, lower floor's terminal 4, lower floor's plastic body 5, upper strata terminal 2, upper strata plastic body 3 and iron-clad 1 according to Secondary to be arranged to make up an entirety from bottom to up, iron-clad 1 and upper strata plastic body 3 limit upper strata SIM card receiving space, lower floor's plastic cement Body 5 limits lower floor's SIM card receiving space with upper strata terminal 2.Pcb board 6 is U-shape structure, is open as lower floor's SIM card plug-and-pull port, Lower floor's terminal 4 is placed among pcb board 6 and connected by the contact 601 corresponding with the both ends of pcb board 6 of terminal pins 401.

Further, the bottom of pcb board 6U types structure is provided with circular groove 602 and forms hand position, convenient to take out lower floor SIM Card.

Further, the equal bending in the head of upper strata terminal 2 and lower floor's terminal 4, this is a kind of anti-routed PIN structural, can be pre- Shell fragment is turned in the antiaircraft fashionable drawing of card insertion, and the relatively common deck of safety coefficient is higher.

Further, upper strata terminal 2 and lower floor's terminal 4 can be and SIM card, Micro-SIM cards or Nano SIM cards Corresponding terminal, terminal 2 and lower floor's terminal 4 select the corresponding terminal of Micro-SIM cards to the present embodiment at the middle and upper levels.

Further, the plug orientation of upper strata SIM card is vertical with the plug orientation of lower floor SIM card, i.e. levels arrangements SIM, which can be that upper strata is horizontal, to be inserted, and the perpendicular slotting or upper strata of lower floor is perpendicular to insert, and lower floor is horizontal to insert.Select upper strata is horizontal to insert in the present embodiment, Slotting pluggable mode is erected by lower floor.

Further, the height of the double-layer mobile phone card holder is 1.65mm.

After above-mentioned design, the mobile phone neck of the present embodiment may be inserted into two Micro-SIM cards, be specially：Upper strata Laterally inserted Micro-SIM cards, lower floor vertically insert Micro-SIM cards, when being connected into by pcb board 6 in mobile phone circuit system, by Then double layer design, the effect for saving interior of mobile phone space is served.

Certainly, upper strata terminal 2 and lower floor's terminal 4 select right with SIM card, Micro-SIM cards or Nano SIM institutes respectively The terminal answered and design different products, and change the product gone out designed by levels SIM card plug orientation, fall within this The protection domain of invention.
