Abstract
The invention provides an SD (Secure Digital)-card assembly, which comprises a card seat and a plurality of conductive terminals, wherein the conductive terminals are fixed in the card seat, and both sides of the conductive part of each conductive terminal are inwards sunken. Inwards-sunken shapes are arranged at both sides of the conductive part of each conductive terminal of the SD-card assembly provided by the invention, so that the electrical-contact points of the conductive terminals and an SD card are more centralized and are not easily contaminated by dust and the like, the contact stability is also greatly improved, the electrical-contact stability is enhanced, and the service life of the SD card is prolonged. In addition, by buckling a slide block at a slide-block buckling position arranged on the card seat of the SD-card assembly, the slide block is prevented form jumping out due to the pressure of a spring in the assembling process, the assembling flow is simplified, and the assembling efficiency is improved.
Description
Technical field
The present invention relates to SD card assembly, relate in particular to improvement the conducting terminal in the Micro SD card assembly.
Background technology
Shown in Fig. 1, the conducting terminal 10 of a plurality of strips generally all is set on the deck 1 of existing Micro SD card (miniature SD card) assembly, be used for conductive contact (the being commonly called as golden finger) conducting of Micro SD card and carry out the signal transmission; In conjunction with referring to shown in Fig. 2; The conduction place of conducting terminal 10 generally is designed to curved surface, circular arc for example, and causing conducting terminal 10 and Micro SD to stick into row is line contact condition (referring to contacting dotted line 101 among Fig. 2) when electrically contacting; This line contact condition makes to be electrically connected inadequately to be stablized; Especially after being infected with dust on conducting terminal 10 or the golden finger or having used a period of time, produce under the situation of distortion, the line contact condition possibly become abnormalities such as multiple spot contact, causes loose contact; Influence the reading and writing data of Micro SD card, even influence the life-span of Micro SD card.
In addition, existing Micro SD clamps that to join process cumbersome, and packaging efficiency is very low.
Summary of the invention
The purpose of this invention is to provide a kind of SD card assembly, be intended to solve the technological deficiency that existing SD card assembly contact performance is not good, packaging efficiency is low.
For realizing the foregoing invention purpose, SD card assembly provided by the invention comprises deck and is fixed on a plurality of conducting terminals in the deck that the both sides at the conduction place of said conducting terminal cave inward.
Further, the both sides at the conduction place of said conducting terminal are the rounding shape that caves inward.
Further, a ccontaining spring and the slide block that offsets with spring in the said deck are provided with the slide block button bit that is interlocked with slide block on the said deck.
Further, said slide block button bit is arranged at the end of deck.
Further, said SD card assembly is a Micro SD card assembly.
Than prior art; SD card assembly provided by the invention is provided with the shape that caves inward through the both sides at the conduction place of conducting terminal; Make that the electrical pickoff of conducting terminal and SD card is more concentrated; Be not easy to receive dust etc. and be infected with, stability in contact also improves greatly, has promoted the stability that electrically contacts and the useful life of SD card.In addition, the present invention fastens slide block through the slide block button bit that is arranged on the deck, and anti-limited slip block pressure owing to spring in assembling process is jumped out, and has simplified assemble flow, has improved efficiency of assembling.

Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Shown in Fig. 3; The SD card assembly that preferred embodiment of the present invention provides is an example with Micro SD card, and it comprises deck 2 and be fixed on a plurality of conducting terminals 21 in the deck 2, in conjunction with referring to shown in Fig. 4; The rounding shape that the both sides 211 at the conduction place of conducting terminal 21 (the P point among the figure) are designed to cave inward; The conduction place 211 of conducting terminal just carries out contacting through P point with SD card (figure do not show) like this, and perhaps points of proximity contact (the P point is electrically contacting of minimum area on every side) state makes electrical pickoff very concentrated; Be not easy to receive dust etc. and be infected with, stability in contact is also very high.
In conjunction with referring to shown in Fig. 3, Fig. 5; Putting spring 20 and the slide block 22 that offsets with spring 20 in the deck 2; The end of deck 2 is provided with a slide block button bit 200, and this slide block button bit 200 fastens slide block 22, prevents it and in assembling process, jumps out from deck 2 owing to the pressure of spring 20; Can reduce the assembling difficulty like this, accelerate packaging efficiency.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention.Though the foregoing description is an example with Micro SD card, the present invention also is applicable to other SD card assemblies.And the present invention also is not limited to the described rounding shape of the foregoing description, can be designed to other suitable shapes that caves inward, or the like.All any modifications of within spirit of the present invention and principle, being done, be equal to replacement and improvement etc., all should be included within protection scope of the present invention.
