Abstract

The utility model relates to a holding fastener for an electronic card, which is arranged on an electronic device and is used for holding an electronic card on the electronic device and electrically connecting with an electric connector which is assembled on a circuit board in the electronic device. The utility model comprises a card holder and an elastic arm arranged on the card seat, wherein, the card holder is provided with a card groove used for containing an electronic card; one side of the elastic arm near the card groove is provided with an elastic clamping part. When the electronic card is inserted, the clamping part is elastically deformed outwards, which is convenient for the electronic card to be inserted into the card groove. When the electronic card is inserted into a preset position, the clamping part goes back to an original position and the electronic card is held at the preset position, ensuring the reliable electrical contact of the electronic card and the electronic card connector. The holding fastener for an electronic card has the advantage of simple structure and no other positioning structures are needed to be arranged on the electronic card connector, which is favorable for reducing the cost. Moreover, inserting the electronic card in the electronic device or taking the electronic card out of the electronic device is more convenient.

Description

Electronic cards holding unit (one)

[technical field]

The utility model relates to a kind of holding unit, refers in particular to a kind of electronic cards holding unit that is applied on the portable electron device.

[background technology]

The prior art relevant with the utility model sees also No. the 6th, 398,572, the United States Patent (USP) of on June 4th, 2002 bulletin, and the subscriber identification module (SIM) that this patent discloses fixes and holds device is the pedestal that is arranged on the electronic card coupler.Wherein electronic card coupler is provided with the head that connects that some and SIM card terminal connect mutually, its laterally relatively both sides be provided with the metal guide part.Vertical opposite end of pedestal is respectively equipped with fixedly barricade and movably spring biased pin, and is provided with guide ramp in the side near the spring biased pin.When inserting SIM card, the spring biased pin is depressed, and SIM card is inserted holding unit from this guide ramp.After SIM card was inserted fully, the spring biased pin resetted, thereby was fixed in this holding unit SIM card is horizontal and vertical by a fixing shelves wall, spring biased pin and metal guide part.For making SIM card can more easily insert this holding unit, the spring of spring biased pin need keep good elasticity, but for SIM card reliably is retained in this fixing structure, this spring needs enough rigidity, thereby higher to material requirements; Especially after SIM card repeatedly plugged, elastic failure easily took place and makes this spring biased pin unstable to vertically fixing of SIM card in this spring, causes SIM card unreliable with contacting of connector.

[utility model content]

The purpose of this utility model is to provide a kind of convenient plug electronic cards, and electronic cards reliably can be retained on electronic cards holding unit wherein.

For achieving the above object, the utility model electronic cards holding unit, be installed in and be used on the electronic installation electronic cards being retained on the electronic installation and electrically connecting with the electric connector that is mounted on the electronic installation internal circuit board, comprise deck and the elastic arm that is installed on this deck, wherein this deck is provided with the draw-in groove of accommodating electronic cards, and elastic arm is provided with clamping part near draw-in groove one side of deck.

Compared with prior art, the utility model is by being provided with elastic arm on the electronic cards holding unit, and resilient clamp portion is set on this elastic arm, when electronic cards is inserted, the outside strain of clamping part and convenient electronic cards is inserted in the draw-in groove, when electronic cards was inserted into the precalculated position, clamping part set back and electronic cards is retained on the precalculated position and guarantees that electronic cards reliably electrically contacts with electronic card coupler.By such setting, this electronic cards holding unit is simple in structure, and electronic card coupler needn't be provided with other location structure and be beneficial to and reduce cost, and electronic cards inserted electronic installation or from electronic installation, takes out this electronic cards all comparatively convenient.

Schematic diagram when Fig. 3 inserts the electronic cards holding unit fully for electronic cards among Fig. 1.

[embodiment]

See also shown in Figure 1, the utility model electronic cards holding unit is installed in electronic installation (not shown), on mobile phone, be used for electronic cards 1 being retained on the electronic installation and electrically connecting with the electric connector 3 that is mounted on the electronic installation internal circuit board 4, comprise deck 2 and elastic arm 5.Wherein deck 2 comprise vertically tabular base portion 20 and certainly these base portion 20 bottom levels extend flat part 21, wherein flat part 21 is provided with the draw-in groove 210 suitable mutually with electronic cards 1 profile near base portion 20 places, and gives prominence in away from base portion 20 1 side direction draw-in grooves 210 in and be provided with two rectangle buckles 211.Base portion 20 middle parts offer one and run through its front and rear surfaces, and the rectangular notch 201 that is connected with described draw-in groove 210, base portion 20 1 sides are provided with the slit 202 that runs through its front and rear surfaces, and base portion 20 is provided with in the groove 203 of notch 201 and slit 202 connections near draw-in groove 210 1 sides.

Elastic arm 5 comprises the main part 51 of long-armed shape and the holding section 52 that autonomous body 51 1 lateral bucklings extend, and wherein main part 51 is provided with the portion of resilient clamp portion 511 of arc away from holding section 52 1 sides, and 511 liang of side bottoms of main part 51 clamping parts are provided with a pair of salient point 512.

See also Fig. 1, Fig. 2 and shown in Figure 3, insert in the slit 202 of base portion the holding section 52 of elastic arm 5, main part 51 is contained in the groove 203 near holding section 52 1 sides, and the arc clamping part 511 of main part 51 is contained in the rectangular notch 201, thereby elastic arm 5 is retained on the deck 2.During use, with the arc guidance part 52 insertion draw-in grooves 210 of electronic cards 1 along elastic arm 5, main part 52 moves backward, thereby makes electronic cards 1 insert draw-in groove 210 at an easy rate fully.Thereby this moment, buckle 212 upper surface that compresses electronic cards 1 simultaneously of clamping part 511 bottoms of main part 51 and flat part 21 was retained on electronic cards 1 in the draw-in groove 210.Simultaneously, the side that salient point 512 supports electronic cards 1 to be preventing electronic cards 1 because of rocking that the gap with draw-in groove 210 produces, thereby makes electronic cards 1 reliably be retained on the electronic cards holding unit 600.

When moving back card, push elastic arm 5 main parts 51 backward, electronic cards 1 one sides skid off along clamping part 511, thereby can easily electronic cards 1 be taken out in draw-in groove 210.

This electronic cards holding unit is the member that is provided with separately in the present embodiment, and certainly, this electronic cards holding unit also can be provided with the housing of electronic installation is whole.
