Abstract

The utility model relates to a dual-purpose card connector, which comprises a main body. The main body is provided with an integrated structure through plastic injection molding. A slot is arranged in the main body. The wall of the slot is respectively arranged with terminal clusters connecting with contacts of an external circuit for a Mini SD memory card and a MS Duo memory card. A terminal cluster connecting with contacts of the Mini SD memory card circuit is positioned at a place adjacent to the slot opening. A terminal cluster connecting with contacts of the MS Duo memory card circuit is arranged far from the slot opening. A contact section of an elastic bending section is positioned and extended towards the slot opening. A stop block is formed at the tail close to a contact terminal on the slot wall. In addition, an anti-seize device is arranged in the slot to realize locating relaying on limiting function of the stop block and the anti-seize device while the Mini SD memory card is inserted in, thus enabling the connector to synchronously connect with a Mini SD memory card and a MS Dou memory storage.

Double-card connector

Technical field

The utility model provides a kind of Double-card connector, mainly is to be improved at the employed connector construction of general storage card.

Background technology

Press, general as digital camera, electric products such as digital code camera, for promoting the storage capacity of its data, and be equipped with the storage card of exclusive form for substitute use in good time outside many, therefore promptly have on the market as shown in Figures 1 and 2 Mini SD storage card A1 and the storage card of the different-format of MS Duo storage card A2, it is respectively the scaled down version of SD storage card and MS storage card, to meet more small-sized 3C electronic installation such as electronic translator, mobile phone, uses such as PDA, so that it connects in order to cooperate with storage card, and then carry out the device that data reads, then need possess equally the plant for storage card of connector that form conforms to is arranged, to constitute the connection of storage card and electric circuit, so that carry out the transmission of data.

Yet, if the connector of single slot is used applicable to these two kinds of storage cards simultaneously, then must in this slot, be provided with respectively the contacted terminal cohort of circuit junction with Mini SD storage card A and MS Duo storage card A2, but because though Mini SD storage card A1 has identical wide spoke with the profile of MS Duo storage card A2, but its length different (length of Mini SD storage card is less than the length of MS Duo storage card), so when often inserting connector because of Mini SD storage card A1, insertion end can't be located and the situation that causes storage card to misplug, and the terminal group faciation conducting that the circuit junction that makes Mini SD storage card A1 can't match with it, and the probability that its terminal is lost because being subjected to the storage card collision also increases relatively, and will influence the normal function of connector, reduce its applicability and practicality on the contrary.

The utility model content

The main purpose of the utility model Double-card connector is by being respectively equipped with the terminal cohort at the slot wall for contacting with the circuit junction of the external circuits of MS Duo storage card and Mini SD storage card, with the insertion end that solves Mini SD storage card in the prior art can't locate and cause storage card misplugs, its circuit junction can't match with it terminal group faciation conducting with and the problems such as probability increase lost because being subjected to the storage card collision of terminal.

The technical solution of the utility model is:

A kind of Double-card connector, be to be provided with slot in the body by plastic material one ejection formation, the wall of slot be respectively equipped with for the contacted terminal cohort of circuit junction of the external circuits of Mini SD storage card and MS Duo storage card, one end of terminal be for the connecting end of electric circuit Joint, in addition end then be for the contacted contact jaw of the circuit junction of external circuits, and constitute the connection of external circuits and electric circuit by the terminal cohort; Wherein,, be located at the opening part near slot with the contacted terminal cohort of the circuit junction of Mini SD storage card, and with the contacted terminal cohort of the circuit junction of MS Duo storage card, then be located at opening part away from slot; The contact jaw of its elasticity bending section is the opening extension towards slot, and be formed with block near the tail end of contact jaw in the slot wall, when storage card inserts, can prevent storage card ora terminalis and the direct collision of terminal tail end, effectively avoid terminal caused and lose, and the generation of short circuit phenomenon, in the slot and be provided with the anti-misoperation device of a MS Duo storage card.

With when when Mini SD storage card inserts, locate by the block effect of block and anti-misoperation device, this connector can be connect for Mini SD storage card and the plant of MS Duo storage card simultaneously.

The utility model Double-card connector not only has preferable terminal group group configuration design space by said structure, more can keep firm structural strength and keep the accuracy of storage card plant and the stability of connection.

Embodiment

For the clear structure of the present utility model of your auditor is formed, and the overall operation mode, cooperate graphic being described as follows now:

The utility model Double-card connector, the basic structure of its whole connector is formed as shown in Figure 3, be to be provided with slot 11 in the body 10 by plastic material one ejection formation, and the terminal cohort 20 that is laid in slot 11 inside constitutes, with by slot 11 plant, and constitute the connection of external circuits and electric circuit by terminal cohort 20 for external circuitses.

And be the connector construction that can plant and use for the external circuits of Mini SD storage card A1 and MS Duo storage card A2 for one in graphic, wherein with the contacted terminal cohort 20 of circuit junction of Mini SD storage card A1, the connecting end 21 of its terminal is located at the opening part near

slot

11,22 of the contact jaws of end extend in slot in addition, in addition with the contacted terminal cohort 20 of circuit junction of MS Duo storage card A2 ', the connecting end 20 of terminal ' be located at opening part away from slot 11, the contact jaw 22 of its elasticity bending section is the opening extension towards slot 11, and be formed with block 12 near the tail end of contact jaw 22 in slot 11 walls, when storage card inserts, can prevent storage card ora terminalis and the direct collision of terminal tail end, effectively avoid terminal caused and lose, and the generation of short circuit phenomenon, and be provided with an anti-misoperation device 13 that prevents MSDuo storage card A2 wrong plug card in the slot 11.
