Description

Memory card connector

[technical field]

The utility model relates to a kind of memory card connector, particularly has one group of terminal structure about a kind of, but can read the connector of two kinds of different memory cards, can apply to the multi-media communication equipment or dial device such as the machine of putting.

[background technology]

Increasing memory card kenel is flooded with in the employed sci-tech product of people day by day, but because of the shape of various memory cards, volume, pin configuration etc. neither identical, so concerning the user, desire to read numerous different memory cards and just need to use the connector compatible with each memory card, not only cause no small economically burden, the independently also scattered difficult arrangement of connector separately, more need spend during use a lot of time search, arrange in pairs or groups can be compatible with memory card connector, cause the waste of time and resource.Though there are many products can read different memory cards simultaneously, all be to utilize different reading devices to reach this function, cause shortcoming bulky, complex structure also though can reach the function of integration.

[utility model content]

The purpose of this utility model is to provide a kind of memory card connector, this connector only needs one group of terminal can read different memory cards respectively, under the situation that does not change the terminal arrangement position, just can use same group of terminal to carry out reading operation by changing the numbers of terminals that electrically conducts with memory card, not only be easy to use, more significantly reduce the volume of this connector.

In order to achieve the above object, the utility model provides a kind of memory card connector, comprise a pedestal, one is placed in the terminal group in the pedestal, one is coated on the outer shielding casing of pedestal, and its terminal comprises that the base portion that is positioned at the bottom reaches the elastic arm by base portion one end bending extension, have on this elastic arm with first contact site of the first memory card conducting and with second contact site of the second memory card conducting, because the part terminal has pressure section, make when second memory card is inserted, because of the terminal that makes second memory card and this have pressure section to urgent pressure section separates, electrically conduct thereby use correct numbers of terminals to produce, and can reach the purpose of utilizing one group of terminal can read different memory cards respectively.

Described memory card connector is characterized in that: this first contact site is in the elastic arm end and be higher than second contact site.

Described memory card connector is characterized in that: this shielding casing has a holding section, can limit the unlikely disengaging of first memory card.

Described memory card connector is characterized in that: this pedestal has the engaging shell fragment, can limit the unlikely disengaging of second memory card.

Described memory card connector is characterized in that: this pedestal has stopping means, can strengthen the contact force of this first memory card and this first contact site or this second memory card and this second contact site.

Described memory card connector is characterized in that: this first memory card can be MMC-Micro card or the memory card similar to the MMC-Micro card structure.

Described memory card connector is characterized in that: this second memory card is MicroSD card or the memory card similar to the MicroSD card structure.

In sum, memory card connector of the present utility model, only need one group of terminal can read two kinds of memory cards respectively, as MicroSD and these two kinds of memory cards of MMC-Micro, it has many identical parts in shape, volume and pin configuration, therefore as long as slightly adjust, under the situation that does not change the terminal arrangement position, just can use same group of terminal to carry out reading operation as long as change the numbers of terminals that electrically conducts with memory card, not only be easy to use, more significantly reduce the volume of this connector.

[embodiment]

See also Fig. 1,2, it is the stereogram of the preferred embodiment of the utility model " memory card connector ", its structure comprises a pedestal 10, one is placed in the terminal group 30 in the pedestal, one is coated on the outer shielding casing 20 of pedestal, and its terminal group 30 comprises the base portion 301 that is positioned at the bottom and by the elastic arm 303 of base portion one end bending extension, have on these elastic arms 303 with first contact site 305 of the first memory card A conducting and with second contact site 307 of the second memory card B conducting, the part terminal has pressure section 309, thereby make when the second memory card B inserts, make the second memory card B separate because of supporting urgent pressure section 309, form not contact condition with the terminal that this has pressure section 309.

The described pedestal 10 of preceding paragraph, its central portion indent become can for two kinds of specification memory cards fixing the space, and separate into first accommodation aperture 60 and second accommodation aperture 70 by the central baffle 205 of shielding casing 20, and both are to arrange up and down and are provided with, and can shared same group of terminal group 30; Aforementioned terminal group 30 is to be fixed on the pedestal 10 in molded (Insert Molding) mode in advance, to save built-up time and to promote yield; Put in pedestal 10 backs in addition and form first groove 103 and second groove 105, insert assembling so that stopping means 40 and engaging shell fragment 50 to be provided respectively.Pedestal 10 has several clamping blocks 101 in addition, can be affixed state with connecting hole 203 mutual engagings of shielding casing 20.

The described stopping means 40 of preceding paragraph, in the utility model preferred embodiment, has protuberance 401 in its both lateral sides, when 103 groups of first grooves on itself and the pedestal 10 are established, after this protuberance 401 is inserted the slotted eye 1031 of first groove 103, and make stopping means 40 slide onto the location via the grooved rail 1033 that is connected with slotted eye 1031 and be fixed by spacing lug 1035, can strengthen the contact force of this first memory card and this first contact site or this second memory card and this second contact site.

The described engaging shell fragment 50 of preceding paragraph, in the utility model preferred embodiment, the one end is a snap-latch piece 501, the other end is engaging protuberance 503, when 105 groups of second grooves on engaging shell fragment 50 and the pedestal 10 are established, the slot 1051 that this snap-latch piece 501 inserts on second groove 105, thus this engaging protuberance 503 passes through the opening 1053 on this second groove 105 and protrudes in first supporting surface 107 (as shown in Figure 4), can limit the unlikely disengaging of second memory card.
