Description

The Holder terminal shell fragment

Technical field

The utility model relates to a kind of Holder terminal shell fragment, refers to a kind of terminal shell fragment that is applied to the SIM card deck especially.

Background technology

Become increasingly prosperous in industry and commerce, today that Science and Technology Day reaches increasingly, mobile phone is played the part of more and more important role in people's life.Simultaneously, people are also more and more higher to the requirement of mobile phone, not only require the mobile phone can be with a plurality of SIM card of fashionable dress, but also require mobile phone to have more large storage capacity, and need extra in addition installing storage card.In order to satisfy above-mentioned requirements, currently used mode is two SIM card to be added a storage card deck combine and be installed in mobile phone inside: be about to two independently SIM card deck and one independently the storage card deck be welded on the cell phone mainboard respectively, or with a double SIM card deck and one independently the storage card deck be welded on the cell phone mainboard respectively, the mainboard area that so takies is bigger, and welding is comparatively frequent.Therefore, the someone expects a plurality of SIM card are connected the machine use that is superimposed together, but so must increase the integral thickness of deck, and common vertical plug-in card mode, must reserve bigger space to the plug-in card action.

Suitable SIM card commonly used at present is the terminal shell fragment of (length direction of card) insertion laterally, its normal contact zone with card is spheroidal or class elliposoidal, but shell fragment is not damaged by the card body during for the assurance plug-in card, must guarantee that the lower limb of shell fragment spheroidal part (or elliposoidal) is lower than the upper surface of plastic cement body, restricted from the outstanding height of plastic cement body surface when therefore making to shell fragment.Especially when a plurality of decks are superimposed together, can smooth and easyly plant in order to guarantee lower floor's SIM card, the lower limb of the spheroidal contact zone (or elliposoidal) of terminal shell fragment can not expose the lower surface of plastic cement body, otherwise lower floor's SIM card can't be inserted.Must satisfy simultaneously under the situation of above two requirements, can only realize, thereby increase the total height of deck by the thickness that increases the plastic cement body

In order to address the above problem, be necessary to design and a kind ofly both can laterally plant for SIM, and the less Holder terminal shell fragment of plastic cement body thickness, constitute the deck of multi-use card even a plurality of decks are superimposed together, also can reduce the integral thickness of deck to greatest extent.

The utility model content

The purpose of this utility model provides a kind of Holder terminal shell fragment that allows SIM card laterally to plant.

Another purpose of the present utility model provides the Holder terminal shell fragment that a kind of limit greatly reduces deck thickness.

Holder terminal shell fragment of the present utility model is arranged on the plastic cement body, and this terminal shell fragment forms one less than 90 ° angle with the direction of insertion of card on along continuous straight runs.

Further, this terminal shell fragment extends upward formation termination contact district along the upper surface of plastic cement body.

Wherein, this terminal shell fragment is the strip shell fragment.

Wherein, on this plastic cement body below this terminal shell fragment, be formed with and the corresponding hollow out of this terminal shell fragment.

Wherein, each terminal shell fragment is parallel to each other.

Useful technique effect of the present utility model is: be arranged in obliquely on the plastic cement body by the terminal shell fragment, not only can as existing spheroidal (elliposoidal) shell fragment, be applicable to the laterally inserted of SIM card equally, need not to reserve bigger space for the plug-in card action; And to make SIM card be the minimum point that first contact terminal shell fragment exposes from this plastic cement body when inserting, and touches the normal contact area of terminal shell fragment and card more gradually, impels the terminal shell fragment can smooth and easy down the distortion and can not damaged by SIM card.Simultaneously, the utility model further adopts inclined type strip shell fragment, make the termination contact district all be higher than the upper surface of plastic cement body, and can not expose the lower surface of plastic cement body, whereby, with the superimposed use of a plurality of decks the time,, also can not insert and cause obstruction lower floor's SIM card even reduce the thickness of plastic cement body.

Description of drawings

Fig. 1 is the deck schematic top plan view of the utility model terminal shell fragment.

Fig. 2 is that the deck of the utility model terminal shell fragment uses schematic diagram.

Embodiment

As shown in Figure 1, be the structural representation of deck 1.Several terminals 12 is embedded on the plastic cement body 11 one-body moldedly, and terminal 12 1 ends form terminal shell fragment 121 from the protruding parts of the upper surface 112 of plastic cement body 11, and this terminal shell fragment 121 is for SIM card Elastic Contact.The peak of terminal shell fragment 121 is termination contact district 123, promptly with the contacted position of SIM card.On the plastic cement body below the terminal shell fragment 121, be formed with and this shell fragment 12 corresponding hollow outs 13; The outside that its these terminal 12 other ends stretch out plastic cement body 11 forms pin 122, is electrically connected for forming with the cell phone mainboard circuit.

Shown in Fig. 1 and 2, in the utility model, in order to reduce the thickness of deck 1, and can allow the laterally inserted of SIM card 2 not damaged by SIM card 2, the applicant has done following improvement to the terminal shell fragment 121 of deck 1: terminal shell fragment 121 arranges in tilting mode, promptly forms one less than 90 ° angle (angle α as shown in Figure 2) with the direction of insertion of SIM card 2 on these terminal shell fragment 121 along continuous straight runs.Wherein, the plane that SIM card is provided with the surperficial place of contact is defined as horizontal direction, and direction of insertion is meant the moving direction when SIM card is inserted.In these cases, terminal shell fragment 121 can be existing laterally inserted sphere or the elliposoidal shell fragment of SIM card that allow, and promptly the contact zone 123 of terminal shell fragment 121 is for protruding from the sphere or the ellipsoid of plastic cement body 11 upper surfaces.Yet, when termination contact district 123 is sphere or ellipsoid, then require the following root edge of sphere or ellipsoid must not be higher than the upper surface of plastic cement body 11, and with the superimposed use of a plurality of decks the time, require the following root edge of sphere or ellipsoid must not expose the lower surface of plastic cement body 11 again, otherwise the SIM card that is inserted into of scratch easily.Therefore, the terminal shell fragment is that the deck of sphere or elliposoidal is made requirement harshness relatively, complexity, and use has limitation.

For this reason, further improvement of the utility model is: terminal shell fragment 121 is for forming strip shell fragment less than 90 ° of angles with the direction of insertion of SIM card on the along continuous straight runs, and those strip shell fragments extend upward along the surface of plastic cement body 11 and form the termination contact district.The strip shell fragment is meant the strip that is shaped as of terminal shell fragment, and it is to realize that by stretching out the surperficial of plastic cement body 11 and forming the contact zone at the peak place end of shell fragment does not have hemisphere or ellipsoid with contacting of SIM card.Whereby, no matter be laterally or vertically to insert in the SIM card process, SIM card is the minimum point exposed from plastic cement body 11 upper surfaces of contact terminal shell fragment 121 at first always, transition touches the normal contact zone 123 of terminal shell fragment 121 and card gradually again, impels the terminal shell fragment 121 can smooth and easy down distortion and can not damaged by SIM card.Therefore, terminal shell fragment of the present utility model not only is equally applicable to the laterally inserted of SIM card, and compared to spherical shell fragment or elliposoidal shell fragment, terminal elastic piece structure of the present utility model is more simple, in making deck 1 process, it is comparatively loose that opposite end bullet sheet 121 protrudes from the requirement for height of plastic cement body 11 upper surfaces, simplified manufacture craft.And, because the direction of insertion of terminal shell fragment of the present utility model and SIM card is formed with an angle, each terminal shell fragment 121 is parallel to each other, allow on limited length direction, arrange more terminal shell fragment 121, simultaneously can also guarantee to have proper spacing between each terminal shell fragment 121, to meet the particular requirement of laterally inserted SIM card to the terminal contact zone.

When a plurality of decks 1 being superimposed together the many cards of formation deck, the contact zone 123 of the strip terminal shell fragment 121 of the utility model inclined type all is positioned at the top of plastic cement body 11, even therefore plastic cement body 11 is extremely thin, can not produce situation yet, therefore just can not form and hinder the insertion of lower floor's card as " the following root edge of spherical shell fragment, elliposoidal shell fragment exposes plastic cement body 11 lower surfaces " and so on.Whereby, can under the situation that reduces plastic cement body 11 thickness, not only allow the laterally inserted of SIM card, simultaneously a plurality of deck 1 when superimposed, can reduced the total height of deck.
