Abstract
The utility model discloses a limiting device for a subscriber identity module (SIM) card of a mobile phone. The limiting device limits the position of the SIM card through a limiting cover which is arranged on an SIM card connector on the circuit board of the mobile phone. The limiting cover is clamped or welded on the shielding case of the circuit board of the mobile phone. Leading-in pins and leading-out pins are respectively arranged at the front end and the rear end of the limiting cover and can facilitate the insertion and the extraction of the SIM card. Since leading-in devices and leading-out devices are designed, the SIM card can be plugged conveniently and the limiting device can be used for all kinds of mobile phones which use unlimited SIM card connectors. Moreover, the limiting device can be directly attached onto the circuit board of the mobile phone, the accuracy is high and the limiting device is convenient to produce.
Description
Technical field
The utility model relates to field of mobile phones, particularly a kind of stopping means of SIM cards of mobile phones.
Background technology
Along with the continuous progress of science, the continuous development of communication tool.The structure of mobile phone, pattern, performance are more apparent also frequent day by day.People are also more and more, more and more higher to the requirement of mobile phone.Existing mobile phone is of a great variety, and from mobile phone development history these years, small and exquisite mobile phone is because of the welcome that is subjected to the client easy to carry always.
The mobile phone size that we use mainly also has the goods of furniture for display rather than for use area of hardware, radio frequency except the restriction that is subjected to display screen, antenna area.General goods of furniture for display rather than for use S IM card connector commonly used all has the spacing plastic cement base portion of X/Y/Z three directions, the plastic cement base that these carry has taken the space of big chip part, make the miniaturization of mobile phone be restricted, the double card double standby mobile phone of special current trend is using two SIM card seats to highlight this problem especially.
Can increase the zone of parts at the sim card connector of selecting no plastic cement base location structure for use, but common like this way is at back cover structure to be set to go to limit X/Y/Z three directions, makes it not occur mobile problem.Because back cover is plastic parts normally, manufacturing tolerance itself adds the elasticity of build-up tolerance and plastic cement, makes to occur falling card problem (being that SIM card contacts with the instantaneous disconnection of deck) easily for SIM spacing under environmental change (fall, littlely fall, thermal shock etc.).
The utility model content
The purpose of this utility model provides a kind of stopping means of SIM cards of mobile phones, has realized the spacing of mobile phone card.
The utility model provides a kind of stopping means of SIM cards of mobile phones, comprise a radome that is arranged on the described circuit board of mobile phone and a limited cover that is located on the described circuit board of mobile phone sim card connector, it is characterized in that, described limited cover is connected on the described radome, the both sides of described limited cover front end have the importing pin of described SIM card, the both sides of rear end have the derivation pin of described SIM card, and described importing pin and derivation pin are to the lateral expansion of described limited cover both sides.
The top of described limited cover has and is horizontal and vertical grooves distributed.
Described limited cover is a stainless steel.
Described limited cover is connected on the described radome, and perhaps, described limited cover is welded on the described radome.
The bottom of described limited cover has some bending legs, described bending leg and described radome clamping.
Adopt the stopping means of a kind of SIM cards of mobile phones described in the utility model, it comes to carry out spacing to SIM card by the limited cover that is arranged on the described circuit board of mobile phone sim card connector, described limited cover clamping or be welded on the radome of described circuit board of mobile phone, the front-end and back-end of limited cover are respectively arranged with and import pin and derive pin, and described importing pin and derivation pin help the insertion of SIM card and extract.The utility model has designed and has imported and exported device, makes things convenient for the plug of SIM card, can be applicable to various uses not with in the spacing sim card connector mobile phone.In addition, directly paster is on circuit board of mobile phone for the utility model, and the precision height is conveniently produced.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a perspective view of the present utility model;
Fig. 3 is the structural representation of limited cover of the present utility model.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
Principal character of the present utility model is to provide reliably spacing and good plug characteristic is provided for SIM card by the SIM card limited cover that is positioned on the radome, reduce SIM card in use fall the card probability.
Referring to Fig. 1 and Fig. 2, stopping means described in the utility model comprises SIM card limited cover 1, sim card connector 2, radome 5, circuit board 4.SIM card limited cover 1 is by the structure engaging or laser spot welding is positioned on the radome 5, and radome 5, sim card connector 2 pasters are on circuit board 4, thereby realization is for the location of SIM card.As an embodiment, SIM card limited cover 1 is selected stainless steel for use.
Referring to Fig. 3, as an embodiment, the effect of the importing pin 101,102 of SIM card limited cover 1 front end is to make things convenient for the insertion of SIM card, derives pin 103,104 effect of putting into and is to make things convenient for extracting of SIM card; SIM card limited cover 1 bending leg 105,106,107 on one side, wherein bending leg 105,106 is stuck in the bottom of radome 5, bending leg 107 is stuck in the top of radome 5, plays the position-limiting action of Z direction, and simultaneously bending leg 105,106 has the spacing of X/Y direction for radome 5.Groove 108 is the transverse concave groove at SIM card limited cover 1 top, when having improved SIM card limited cover 1 bulk strength, cooperates longitudinal fluting 109, has increased effective spacing for the Z direction of SIM card.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of above embodiment.
