Abstract
The utility model discloses an insulation structure of an SIM (subscriber identity module) card metal support. The insulation structure comprises a PCB (printed circuit board), an SIM card seat arranged on the PCB and an SIM card located on the SIM card seat. The insulation structure also comprises the SIM card metal support between the PCB and the SIM card, and insulation paint or printing ink is coated on the surface of the SIM card metal support. The insulation paint or printing ink is coated in a spraying or silk-screen method. Compared with the prior art, in the insulation structure of the SIM card metal support, the insulation paint or printing ink is covered on the surface of the SIM card metal support in a spraying or silk-screen method, so as to prevent the contact between a copper sheet of the SIM card and the SIM card metal support to cause short circuit, thereby effectively solving the problem of poor contact of the SIM card and improving the reliability of the SIM card seat.
Description
Technical field
The utility model relates to a kind of SIM cards of mobile phones, particularly relates to a kind of insulation system of SIM metallic support.
Background technology
Present stage the mobile phone electronic product, the compact frivolous development of forward.When design, how saving the pcb board space has become an important problem.Plastic rubber bracket integral type SIM seat; Because it is bigger that its plastic rubber bracket partly takes up room, and the plastic rubber bracket reliability is low, when design, begun to use in a large number the metallic support form now; Below the SIM support, also can put the IC element like this; Saved the space, secondly the direct paster of SIM support is on pcb board, and reliability is higher.But a large amount of uses along with metal SIM support; Have to consider how to prevent the problem of SIM support and SIM copper sheet short circuit causing card again; Traditional approach mainly is to paste one deck insulating trip at the SIM rack surface; Like the PET sheet, such mode has following drawback: 1) the insulating trip gum is prone to lose efficacy under ambient temperature is impacted; Be prone to when 2) SIM plugs the insulating trip corner is swept.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of insulation system of SIM metallic support is provided, and has improved the attachment reliability of insulating barrier and metal support surface effectively, the reinforced insulation performance.
In order to achieve the above object; The technical scheme that the utility model adopts is: a kind of insulation system of SIM metallic support; Comprise pcb board, be arranged at the SIM seat on the pcb board and be positioned at the SIM on the SIM seat; Described insulation system also comprises the SIM metallic support between pcb board and SIM, and the surfaces coated of SIM metallic support is covered with insulating paint/printing ink.
Further, described insulating paint/printing ink is spraying or silk-screen.
Compared with prior art; The beneficial effect of the utility model is: SIM support insulation system covers insulating paint or printing ink the surface of SIM metallic support through the mode of spraying or silk-screen; Cause short circuit to prevent that the SIM copper sheet from contacting with the SIM metallic support; Fall the card problem thereby efficiently solve SIM, improve the reliability of SIM seat.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the local enlarged diagram of the utility model.
Embodiment
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, so that the technical characterictic and the advantage of the utility model are carried out more deep annotation.
Like Fig. 1, shown in 2; A kind of insulation system of SIM metallic support; Comprise pcb board 5, be arranged at the SIM seat 1 on the pcb board 5 and be positioned at the SIM 2 on the SIM seat 1; Described insulation system also comprises the SIM metallic support 3 between pcb board 5 and SIM 2, and the surfaces coated of SIM metallic support 3 is covered with insulating paint/printing ink 4.
Further, described insulating paint/printing ink 4 is spraying or silk-screen.
This structure covers the surface of SIM support with insulating paint or printing ink through the mode of spraying or silk-screen, solved the insulating trip corner and has been prone to the problem that swept by SIM, and the area that covers of insulating paint or printing ink shell is wider simultaneously, has improved insulation effect.Be mainly used on the electronic products such as mobile phone, digital product, all applicable for the insulation of various metallic supports, sheet metal.
The above is the utility model preferred embodiment, and under the prerequisite of the inventive concept that does not break away from the utility model, any conspicuous replacement is all within the protection range of the utility model.
Claims (2)
1. the insulation system of a SIM metallic support; Comprise pcb board (5), be arranged at the SIM seat (1) on the pcb board (5) and be positioned at the SIM (2) on the SIM seat (1); It is characterized in that: described insulation system also comprises the SIM metallic support (3) that is positioned between pcb board (5) and the SIM (2), and the surfaces coated of SIM metallic support (3) is covered with insulating paint/printing ink (4).
