Description

Technical Field

[0001] The utility model relates to the field of storage cards, in particular to a new connection structure of an SD shell assembly. Background Art

[0002] Secure Digital, or SD, is a card that, as its name suggests, offers superior security compared to CF cards and earlier SM cards. Jointly developed by Panasonic, Toshiba, and SanDisk, it is a new memory card product. Its key feature is its encryption, ensuring data security and confidentiality. In many ways, the SD card can be considered an upgrade to the MMC. While both cards share the same form factor and function, the MMC card is slightly thinner. However, any device that accepts SD cards can also accept MMC cards.

[0003] SD cards primarily consist of an insulating body and components mounted within it. To enhance overall structural strength, existing SD card structures employ metal upper and lower covers that interlock with each other on either side of the insulating body. However, due to the inherent rigidity of the metal components, these components can easily become misaligned due to dimensional deviations. This necessitates precise machining of the two components, leading to increased processing costs and a complex process. Consequently, improvements to existing SD card structures are necessary. Utility Model Content

[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a new connection structure for SD shell assembly, which can effectively solve the problems of the existing SD card with high precision requirements, high processing costs and complicated fastening process.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A novel connection structure for an SD housing assembly includes an insulating body, a lower cover, and an upper cover. The insulating body is provided with a mounting slot for mounting components, and one end of the insulating body is provided with a plug-in portion for mating with an external plug. The lower cover is embedded in the insulating body and covers one side wall of the insulating body, and the lower cover is made of metal. The upper cover is buckled onto the insulating body and located on the other side wall of the insulating body, and the upper cover is made of metal. The mounting slot is located between the upper cover and the lower cover, and the plug-in portion is located outside the lower cover.

[0007] As a preferred solution, the side wall of the insulating body is recessed inwardly with a first groove that cooperates with the lower cover, and the mounting groove is formed by the bottom of the first groove passing through the other side wall of the insulating body. The lower cover is arranged in the first groove, and the outer side wall of the lower cover is flush with the outer side wall of the insulating body.

[0008] As a preferred solution, a fixing portion is integrally extended outward from the outer periphery of the lower cover, and the fixing portion is embedded in the surrounding side walls of the first groove.

[0009] As a preferred solution, a second groove cooperating with the upper cover is formed on the side wall of the insulating body, the upper cover is buckled into the second groove, and the outer side wall of the upper cover is flush with the outer side wall of the insulating body.

[0010] As a preferred solution, a plurality of button holes arranged at intervals are provided in the second groove, and a button portion cooperating with the button hole is integrally formed on the upper cover. The button portions are multiple and arranged at intervals, and each button portion cooperates with the corresponding button hole and is buckled together.

[0011] As a preferred solution, the insulating body is made of plastic.

[0012] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0013] The lower cover is embedded in the insulating body and covers one side wall of the insulating body, and cooperates with the upper cover to be buckled on the insulating body and located on the other side wall of the insulating body, so that the lower cover is molded on the insulating body by injection molding. When buckling, it is only necessary to buckle the upper cover and the insulating body together. Since the insulating body is relatively soft, it can be deformed to a certain extent when buckling. Even if the size of the upper cover deviates within a certain range, it will not affect the buckling process, thereby reducing the processing accuracy requirements of the upper cover and lowering the processing cost. At the same time, the buckling process between the metal parts and the insulating parts is also more convenient, avoiding deformation of the upper cover during the buckling process.

[0014] In order to more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figures 1 to 4 , which shows the specific structure of a preferred embodiment of the present invention, including an insulating body 10 , a lower cover 20 and an upper cover 30 .

[0026] The insulating body 10 has a mounting groove 101 for mounting components. One end of the insulating body 10 is provided with a plug-in portion 11 for external plugging. In this embodiment, the sidewall of the insulating body 10 is recessed with a first groove 102 that mates with the lower cover 20. The mounting groove 101 is formed by the bottom of the first groove 102 extending through the other sidewall of the insulating body 10. The sidewall of the insulating body 10 also has a second groove 103 that mates with the upper cover 30. This second groove 103 contains a plurality of spaced-apart button holes 104. The insulating body 10 is made of plastic.

[0027] The lower cover 20 is embedded in the insulating body 10 and covers a side wall of the insulating body 10. The lower cover 20 is made of metal. In this embodiment, the lower cover 20 is set in the first groove 102. The outer wall of the lower cover 20 is flush with the outer wall of the insulating body 10, making the overall integrity better and the appearance more in line with consumer needs. The outer periphery of the lower cover 20 extends outward to form a fixed portion 21. The fixed portion 21 is embedded in the four side walls of the first groove 102. The fixed portion 21 cooperates with the side walls of the first groove 102 to prevent the lower cover 20 from falling off the insulating body 10. In this embodiment, the fixed portions 21 are arranged in a plurality at intervals, and each side wall of the lower cover 20 is provided with two fixed portions 21 arranged at intervals.

[0028] The upper cover 30 is snapped onto the insulating body 10 and is located on the other side wall of the insulating body 10. The upper cover 30 is made of metal; the mounting groove 101 is located between the upper cover 30 and the lower cover 20. The metal upper cover 30 and the lower cover 20 can not only protect the internal components, but also shield the external electric field, magnetic field and electromagnetic field from interfering with the working process of the internal components. The plug-in portion 11 is located on the outside of the lower cover 20. In this embodiment, the upper cover 30 is snapped into the second groove 103, and the outer wall of the upper cover 30 is flush with the outer wall of the insulating body 10, so that the upper cover 30 and the insulating body 10 are more integrated, further ensuring the integrity of the product itself, not only preventing the upper cover 30 from falling off under the action of external force, but also making the overall appearance better. The upper cover 30 is integrally formed with a buckle portion 31 that cooperates with the buckle hole 104. The buckle portions 31 are arranged in a plurality at intervals, and each buckle portion 31 cooperates with and buckles with a corresponding buckle hole 104, so that the upper cover 30 is buckled on the insulating body 10 through the cooperation between the buckle portion 31 and the buckle hole 104.

[0029] The assembly process of this embodiment is described in detail as follows:

[0030] During processing, the lower cover 20 and the upper cover 30 are first stamped out, then the lower cover 20 is placed in a mold, and the insulating body 10 is molded by injection molding, and then the components are installed in the mounting groove 101 and on the plug-in portion 11 on the insulating body 10; finally, the upper cover 30 is buckled into the second groove 103 through the cooperation of the buckle portion 31 and the corresponding buckle hole 104.

[0031] The design focus of the present utility model is that the lower cover is embedded in the insulating body and covers one side wall of the insulating body, and cooperates with the upper cover to be buckled on the insulating body and located on the other side wall of the insulating body, so that the lower cover is molded on the insulating body by injection molding. When buckling, it is only necessary to buckle the upper cover and the insulating body together. Since the insulating body is relatively soft, it can be deformed to a certain extent when buckling. Even if the size of the upper cover deviates within a certain range, it will not affect the buckling process, thereby reducing the processing accuracy requirements of the upper cover and lowering the processing cost. At the same time, the buckling process between the metal part and the insulating part is also more convenient, avoiding deformation of the upper cover during the buckling process.

[0032] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
