Abstract

The utility model discloses a connector. Several groups of the cohesion terminals which are used to contact the connecting points of the storage card circuit are arranged in a slot of the connector. Each group of the cohesion terminals are arranged in the fixed position according to the format of the storage card. A plurality of groove is provided in the inner edge of the slot which is matched with the corresponding broad width of the storage card. A convex part which is conformed to a guiding groove of each storage card is provided between the groove parts. The advantage of the utility model is that every convex part is provided on the same side of the slot. Thus the storage card can be inserted into the slot of the connector with one face of the guiding groove facing the same direction.

Description

Card connector

Technical field

The utility model discloses a kind of connector, be intended to be improved at the inserting slot construction of card connector, mainly with the protuberance of slot in order to be involutory with each storage card guide channel (error-proof structure), be located at the same side of slot, each storage card is inserted in the slot of connector in the one side mode in the same direction with guide channel, to provide a kind of storage card plant direction of avoiding to obscure, prevent that effectively storage card from planting wrong and cause the card connector of short circuit.

Background technology

As shown in Figure 1, structure stereoscopic figure for general common store card connector A, its connector A be provided with in its slot A1 inside some groups in order to the contacted terminal A2 that is connected of the circuit junction of various form storage cards, and its slot A1 inner edge then cooperates the wide cut of each institute's corresponding stored card and is provided with some slot part A11, locate for the storage card plant of particular form with each slot part A11 by slot A1, so that storage card is able to pairing to be connected terminal A2 involutory really, and then constitute the connection of storage card and electric circuit.

Again, as Fig. 2 (A), 2 (B), 2 (C), shown in 2 (D), be the comparatively approaching MS storage card B1 of overall dimension in the market, SD storage card B2, the contour structures schematic diagram of XD storage card B3 and MMC storage card B5, wherein, SD storage card B2 and XD storage card B3 are provided with guide channel B4 in the one side of its circuit junction, its guide channel B4 is so-called error-proof structure, be involutory with the recess that cooperates and storage card slot is set, guarantee that storage card inserts in the slot with being connected the terminal direction that is involutory with the one side that is provided with circuit junction, avoids taking place the phenomenon that storage card misplugs.

Yet; when the storage card that overall dimension is close is integrated in the connector use of single slot; because each storage card inserts in the space of same slot; only reach positioning action with the involutory back of each corresponding slot part respectively; when the less storage card of wide cut inserts the bigger position of slot part width; still can't find storage card wrong plug position immediately; be also noted that whether insert still more to direction; therefore regular meeting can't normally use because of the wrong plug of storage card direction; can cause short circuit phenomenon with being connected termination contact of different-format because of the circuit junction of storage card even, the serious damage that more will cause terminal.

Technology contents

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of storage card plant direction of avoiding to obscure, and prevents that effectively storage card from planting wrong and cause the card connector of short circuit.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of card connector, being provided with one between main body and loam cake can be for the slot of specific format storage card plant, slot inside be provided with some groups in order to the contacted terminal that is connected of the circuit junction of various form storage cards, the slot inner edge then cooperates the wide cut of each institute's corresponding stored card and is provided with some slot parts, and between slot part, be provided with and the guide channel of each storage card protuberance of fit mutually, storage card is able to pairing to be connected terminal involutory really, and then the connection of formation storage card and electric circuit, wherein:

The guide channel of described and each storage card each protuberance of fit mutually is located at the same side of slot.

Card connector of the present utility model be laid with in the slot inside of connector equally some groups in order to the contacted terminal that is connected of the circuit junction of various form storage cards, each group is connected the position that terminal is being fixed according to the format configuration of affiliated storage card, the inner edge of this slot then cooperates the wide cut of each institute's corresponding stored card and is provided with some slot parts, and between slot part, be provided with and the guide channel of each storage card protuberance of fit mutually, wherein, each protuberance is located at the same side of slot, each storage card is inserted in the slot of connector in the one side mode in the same direction of tool guide channel, to avoid storage card plant direction to obscure, prevent that effectively the storage card plant is wrong and cause short circuit.

And, further will be connected the terminal employing will be in order to dispose with the mode of the contacted end of storage card towards the extension of storage card direction of insertion, prevent from directly to collide when storage card from inserting, to avoid causing losing of linking terminal because of the error of storage card with the end that is connected terminal.

Embodiment

For the clear structure of the present utility model of your auditor is formed, and the overall operation mode, existing conjunction with figs. is described as follows:

The utility model card connector, the basic structure of its whole connector is formed as shown in Figure 3, being provided with one between main body 10 and loam cake 10 ' can be for the slot 11 of specific format storage card plant, slot 11 inside be provided with some groups in order to the contacted terminal 12 that is connected of the circuit junction of various form storage cards, slot 11 inner edges then cooperate the wide cut of each institute's corresponding stored card and are provided with some slot parts 111, to locate (MS storage card B1 for example shown in Figure 4 and MMC storage card B5 shown in Figure 7) with storage card plant for specific format by each slot part 111 of slot 11, storage card is able to pairing to be connected terminal 12 involutory really, and then constitutes the connection of storage card and electric circuit.
