(3)发明内容(3) Contents of the invention

本发明的一目的是提供一种个人电脑标准界面卡(PC)及其保护壳，可简化所需的组装制程并加强PC卡的结构强度。An object of the present invention is to provide a personal computer standard interface card (PC) and its protective case, which can simplify the required assembly process and enhance the structural strength of the PC card.

本发明的个人电脑标准界面卡包括上盖、下盖、塑胶框架与电路板。其中，上盖具有一对连续折弯约90度两次形成的扣爪造型于其两侧。下盖的两侧则具有一对滑动面弯角，并再连接一对嵌入型弯角。上盖扣爪，可顺着下盖的对滑动面弯角滑下，并扣紧下盖。而塑胶框架的两侧，具有一对凹槽，以嵌合下盖上的嵌入型弯角。因此，其中上盖、下盖与塑胶框架共同形成本发明的PC卡的保护壳，因此，塑胶框架不仅为滑动面弯角所包覆，更为嵌入型弯角所嵌合。电路板是为PC卡的电子零件与印刷电路板的组合，安装于塑胶框架中。上盖与下盖均可使用金属材质，以加强其结构强度与防电磁波的能力。The personal computer standard interface card of the present invention comprises an upper cover, a lower cover, a plastic frame and a circuit board. Wherein, the upper cover has a pair of buckle claws formed by continuous bending at about 90 degrees twice on both sides. The two sides of the lower cover have a pair of sliding surface bends, and are connected with a pair of embedded bends. The claws of the upper cover can slide down along the curved corner of the opposite sliding surface of the lower cover, and fasten the lower cover. The two sides of the plastic frame have a pair of grooves to fit the embedded corners on the lower cover. Therefore, the upper cover, the lower cover and the plastic frame jointly form the protective shell of the PC card of the present invention, therefore, the plastic frame is not only covered by the corner of the sliding surface, but also fitted by the embedded corner. The circuit board is a combination of the electronic components of the PC card and the printed circuit board, mounted in a plastic frame. Both the upper cover and the lower cover can be made of metal to enhance their structural strength and anti-electromagnetic wave capability.

上述的滑动面弯角，由下盖的侧边折弯后，形成约45度至90度弯角，而较佳的角度约为70度。上述的嵌入型弯角，则由滑动面弯角外缘再折弯后所形成约为30至60度，较佳的角度约为45度。The above-mentioned curved angle of the sliding surface is bent from the side of the lower cover to form a curved angle of about 45 degrees to 90 degrees, and a preferred angle is about 70 degrees. The above-mentioned embedded corner is formed by bending the outer edge of the sliding surface at about 30 to 60 degrees, and the preferred angle is about 45 degrees.

本发明利用上盖上的扣爪、下盖的滑动面弯角嵌入型弯角，以及塑胶框架的凹槽，共同简化了PC卡的组立制程，更加强了PC卡的结构强度。且上下盖的造型，还具有防止与抵抗电磁波干扰的功能。The present invention utilizes the clasps on the upper cover, the embedded corners of the sliding surface of the lower cover, and the grooves of the plastic frame to jointly simplify the assembly process of the PC card and further strengthen the structural strength of the PC card. Moreover, the shape of the upper and lower covers also has the function of preventing and resisting electromagnetic wave interference.

为进一步说明本发明的目的、结构特点和效果，以下将结合附图对本发明进行详细的描述。In order to further illustrate the purpose, structural features and effects of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

(5)具体实施方式(5) specific implementation

参阅图2A，它为本发明的较佳实施例的PC卡上下盖组立前的侧视示意图。如图中所示，本发明的PC卡外壳可分为上盖210与下盖220。而本发明的上下盖的特点在于下盖220的两侧具有一预定的滑动面弯角造型。当上盖210欲结合下盖220时，仅需将上盖210向下盖220压下，即可利用下盖220上的滑动面弯角造型顺利地滑下，上盖210两侧边缘紧紧的扣住下盖220的两侧。Referring to FIG. 2A , it is a schematic side view of the upper and lower covers of the PC card before the assembly of the preferred embodiment of the present invention. As shown in the figure, the PC card casing of the present invention can be divided into an upper cover 210 and a lower cover 220 . The feature of the upper and lower covers of the present invention is that both sides of the lower cover 220 have a predetermined curved angle shape of the sliding surface. When the upper cover 210 is to be combined with the lower cover 220, only the upper cover 210 needs to be pressed down to the lower cover 220, and the sliding surface angle shape on the lower cover 220 can be used to slide down smoothly, and the edges on both sides of the upper cover 210 are tight. Buckle the two sides of the lower cover 220.

参见图2B，如图中所示为图2A中PC卡上下盖组立后的示意图。当上下盖因受到压力后，因为上述的滑动面弯角造型，使得上盖210可轻易地与下盖220相结合。虽然，本发明的上下盖结合的方式相当容易，仅需将上下盖施压即可，但由于上下盖两侧的弯角的设计，使得本发明的上下盖有着容易结合，但却能维持相当好的固定强度。也就是说，当本发明的上下盖结合后，由于上盖210已卡住下盖220的两侧，并稳定的扣住下盖的两侧，除非使用工具或施以巨大的力量才能卸离。Referring to FIG. 2B , it is a schematic diagram of the upper and lower covers of the PC card in FIG. 2A after assembly as shown in the figure. When the upper and lower covers are under pressure, the upper cover 210 can be easily combined with the lower cover 220 because of the curved shape of the above-mentioned sliding surface. Although the method of combining the upper and lower covers of the present invention is quite easy, it only needs to apply pressure to the upper and lower covers, but due to the design of the curved angles on both sides of the upper and lower covers, the upper and lower covers of the present invention are easy to combine, but they can maintain a considerable Good fixing strength. That is to say, when the upper and lower covers of the present invention are combined, since the upper cover 210 has locked the two sides of the lower cover 220 and stably fastens the two sides of the lower cover, it cannot be released unless tools are used or a huge force is exerted. .

参见图3，如图中所示是为图2A中PC卡上下盖组立后的细部结构示意图。本发明的PC卡的上盖210的两侧均具有一连续折弯大约90度两次的扣爪造型。本发明的PC卡的下盖220不仅具有一角度310的滑动面弯角造型，还具有另一角度320的折边。角度310是用来使上盖210与下盖220组立时，形成一滑动面，使上盖210的两侧扣爪顺着角度310方向滑行，进而包覆下盖220。此滑动面弯角造型的角度310，其范围约大于45度并小于90度，只要可发挥帮助上盖210与下盖220组立的功能即可，而较佳的角度约为70度。Referring to FIG. 3 , as shown in the figure is a schematic diagram of the detailed structure after the upper and lower covers of the PC card in FIG. 2A are assembled. Both sides of the upper cover 210 of the PC card of the present invention have a buckle shape that is continuously bent about 90 degrees twice. The lower cover 220 of the PC card of the present invention not only has a curved shape of the sliding surface at an angle 310 , but also has a folded edge at another angle 320 . The angle 310 is used to form a sliding surface when the upper cover 210 and the lower cover 220 are assembled, so that the claws on both sides of the upper cover 210 slide along the direction of the angle 310 to cover the lower cover 220 . The angle 310 of the curved shape of the sliding surface ranges from about 45 degrees to less than 90 degrees, as long as it can help the upper cover 210 and the lower cover 220 to be assembled, and the preferred angle is about 70 degrees.

本发明的PC卡的下盖220的两侧在形成角度310后，更进一步的再内弯一角度320，形成一内弯的扣紧造型，此内弯的扣紧造型具有嵌入塑胶框架330的功能。使用本发明的下盖220可将塑胶框架330紧紧的嵌合，如图中所示，下盖220两侧的末端的扣紧造型，有效地嵌入塑胶框架330中，而塑胶框架330上亦形成相对应的凹槽，以配合下盖220与塑胶框架330的嵌合。故使本发明的PC卡的强度更为加强，也使得本发明的PC卡在使用时更不易损坏。大幅提高PC卡的实用性与携带性。此内弯的角度320，一般可使用约30至60度的弯角，较佳的角度约为45度。上述的上盖210与下盖220，一般来说，均可使用金属材质来制造，以方便加工成形，并与塑胶框架330共同形成本发明PC卡的保护壳。After the two sides of the lower cover 220 of the PC card of the present invention form an angle 310, they are further bent inward by an angle 320 to form an inwardly bent fastening shape, which has a plastic frame 330 embedded in it. Function. Using the lower cover 220 of the present invention can tightly fit the plastic frame 330, as shown in the figure, the fastening shape of the ends on both sides of the lower cover 220 is effectively embedded in the plastic frame 330, and the plastic frame 330 is also Corresponding grooves are formed to fit the lower cover 220 and the plastic frame 330 . Therefore, the strength of the PC card of the present invention is strengthened, and the PC card of the present invention is less likely to be damaged during use. Greatly improve the practicability and portability of PC cards. The angle 320 of the inward bend is generally about 30 to 60 degrees, preferably about 45 degrees. Generally speaking, the above-mentioned upper cover 210 and lower cover 220 can be made of metal materials to facilitate processing and forming, and together with the plastic frame 330 form the protective shell of the PC card of the present invention.

因此，本发明的PC卡将电路板放入下盖220中，此时下盖220已紧密地嵌合塑胶外框330。再将上盖210压下使其扣紧下盖220，即可完成本发明的PC卡的组合，不仅组立简单且具有良好的结构强度。上述的电路板，是为PC卡的控制与功能电路的印刷电路板及其上的零件。Therefore, in the PC card of the present invention, the circuit board is put into the lower cover 220 , and the lower cover 220 has tightly fitted the plastic outer frame 330 at this moment. Then press down the upper cover 210 to fasten the lower cover 220 to complete the combination of the PC card of the present invention, which is not only easy to assemble but also has good structural strength. Above-mentioned circuit board is the printed circuit board of the control and function circuit of PC card and parts on it.
