Thus, the appearances of the above phrases in various places throughout this specification are not necessarily referring to the same embodiment or example of the present disclosure. Furthermore, the particular features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples. Moreover, those skilled in the art can combine different embodiments or examples described in this specification as well as features of different embodiments or examples on the premise of no mutual contradictions.
Referring to
A terminal 200 according to embodiments of the present disclosure includes the card holder 20. Further, the terminal 200 also includes the card socket 10. The terminal 200 may be various devices that can acquire data from the data card 300 and process the data, or that can import data into the data card 300, and for example, the terminal 200 can be a mobile phone, a tablet computer, a computing device, an information display device, or the like.
Referring to
Respective thicknesses of the first side wall 213, the second side wall 214 and the fourth side wall 216 can be equal, so as to allow the card holder 20 to be inserted into the card socket 10 easily. The third side wall 215 includes two end portions 2152 coupled to the second side wall 214 and the fourth side wall 216 correspondingly, and a middle portion 2154 coupling the two end portions 2152. A height of each end portion 2152 is equal to a height of the second side wall 214 and a height of the fourth side wall 216, correspondingly, so as to make it convenient for the two end portions 2152 to abut against the data card 300 to assist in fixing the data card 300. A height of the middle portion 2154 is lower than the height of each end portion 2152, such that the contact terminal can conveniently extend into the card slot 211 from the middle portion 2154 and make contact with the metal contact 30. Further, a side of the middle portion 2154 away from the card slot 211 defines a chamfer, so as to facilitate insertion of the contact terminal from the middle portion 2154 into the card slot 211.
Referring to
The elastic element 23 is coupled to the sliding block 22, and configured to press the sliding block 22 in a deformation state so that the sliding block 22 abuts against the data card 300. Specifically, the elastic element 23 and the sliding block 22 can be integrally formed or separately formed, respective materials of the elastic element 23 and the sliding block 22 can be consistent or inconsistent, and the elastic element 23 can be fixedly or movably coupled to the sliding block 22. It could be understood that the elastic element 23 can be transformed between a natural state and a deformation state, and when the card slot 211 hasn't received the data card 300, the elastic element 23 is in the natural state and does not press the sliding block 22, and thus the sliding block 22 is inserted into the card slot 211 by the first depth D1 along the first direction. When the data card 300 needs to be installed in the card slot 211, the first side of the data card 300 abuts against the abutting surface 222 and urges the sliding block 22 to slide in the sliding groove 212 to reach the second depth D2 by which the sliding block 22 is inserted into the card slot 211 along the first direction, and a second side of the data card 300 abuts against the two end portions 2152 of the third side wall 215, such that the data card 300 is received in the card slot 211, the elastic element 23 is in the deformation state and presses the sliding block 22 along the first direction, and the data card 300 is firmly installed in the card slot 211 under the abutting action of the sliding block 22 and the end portions 2152.
In the card holder 20, the inserting device 100 and the terminal 200 mentioned above, the elastic element 23 can press the sliding block 22 in the deformation state, such that the sliding block 22 can abut against the data card 300 when the data card 300 is received in the card slot 211, and hence the data card 300 can be firmly installed on the card holder 20 and will not be detached from the card holder 20 when the card holder 20 is flipped over.
The card tray 21 further includes an upper surface 217 (as an example of the first surface) and a lower surface 218 (as an example of the second surface), and the lower surface 218 is opposite the upper surface 217. Specifically, the upper surface 217 can be parallel to the lower surface 218 to push the card holder 20 into the card socket 10 easily. When the card holder 20 needs to be installed in the card socket 10, the card holder 20 is usually rotated to a state where the upper surface 217 faces upwards and the lower surface 218 faces downwards, and then the card holder 20 is further pushed into the card socket 10.
In some embodiments, one card slot 211 is provided. The card slot 211 and the sliding groove 212 are each defined in the upper surface 217, and neither the card slot 211 nor the sliding groove 212 passes through the lower surface 218, such that the data card 300 will not fall off when the upper surface 217 faces upwards, and meanwhile the data card 300 can be installed in the card slot 211 easily, the state of the sliding block 22 can be observed easily, and the sliding block 22 can be assembled and disassembled easily.
In some embodiments, two card slots 211 are provided and include an upper card slot 2111 (as an example of the first card slot) and a lower card slot 2112 (as an example of the second card slot), and the upper card slot 2111 is defined in the upper surface 217 while the lower card slot 2112 is defined in the lower surface 218. The sliding groove 212 is defined in the upper surface 217, the sliding groove 212 passes through the upper card slot 2111 and partially penetrates into the lower card slot 2112 in a depth direction, and the sliding block 22 can abut against the data card 300 when the data card 300 is received in the upper card slot 2111 or when the data card 300 is received in the second card slot 2112, or when the date card 300 is received in each of the first card slot 2111 and the second card slot 2112. As a result, the card holder 20 can receive two data cards 300 at the same time, which expands the function of the terminal 200 and makes the structure of the card holder 20 compact. Specifically, depending on specific use requirements, the data card 300 can be installed in each of the upper card slot 2111 and the lower card slot 2112, or the data card 300 can be installed in the upper card slot 2111 instead of the lower card slot 2112, or the data card 300 can be installed in the lower card slot 2112 instead of the upper card slot 2111. The position of the upper card slot 2111 can be corresponding to that of the lower card slot 2112, and an opening depth of the upper card slot 2111 and that of the lower card slot 2112 can be the same or can be different. The sliding groove 212 passes through the upper card slot 2111 and partially penetrates into the lower card slot 2112 in the depth direction, that is, the sliding groove 212 runs through the upper surface 217 and a bottom of the upper card slot 2111, and partially penetrates into the lower card slot 2112, and the sliding groove 212 is spaced apart from the lower surface 218.
Accordingly, in some embodiments, the card tray 21 further includes a partition plate 21a, and the partition plate 21a is disposed between the upper card slot 2111 and the lower card slot 2112 and configured to separate the data card 300 received in the upper card slot 2111 from the data card 300 received in the lower card slot 2112. Thus, the partition plate 21a can separate two data cards 300, such that when one data card 300 is installed or uninstalled, the other data card 300 will not be affected. Additionally, the partition plate 21a can hold the data card 300 and prevent the data card 300 from falling off in a direction perpendicular to the upper surface 217 and the lower surface 218. Specifically, two partition plates 21a are provided and extend into the card slot 211 correspondingly from the second side wall 214 and the fourth side wall 216.
In some embodiments, the card tray 21 further includes a fixing groove 219, the fixing groove 219 is defined in the upper surface 217 and communicated with the sliding groove 212, and the elastic element 23 is received in the fixing groove 219. The fixing groove 219 includes a first wall 2191 adjacent to the card slot 211 and a second wall 2192 opposite the first wall 2191, and the second wall 2192 gradually extends away from the card slot 211 along a direction from two ends of the fixing groove 219 to a middle position of the fixing groove 219.
Therefore, the state of the elastic element 23 can be easily observed, and the elastic element 23 can be assembled or disassembled easily. Meanwhile, the second wall 2192 gradually extends away from the card slot 211 along the direction from two ends of the fixing groove 219 to the middle position of the fixing groove 219, that is, a width of the fixing groove 219 is gradually increased in the direction from two ends of the fixing groove 219 to the middle position of the fixing groove 219. As a result, when the elastic element 23 is deformed, friction between the elastic element 23 and the second wall 2192 is reduced, thereby prolonging the service life of the elastic element 23. Specifically, the fixing groove 219 extends along the second direction overall, and the first wall 2191 extends along the second direction. In one embodiment, two ends of the elastic element 23 are fixed at two ends of the fixing groove 219, specifically by means of gluing. In another embodiment, the elastic element 23 can abut against an inner wall of the fixing groove 219, and when the elastic element 23 is deformed, the elastic element 23 abuts against the inner wall of the fixing groove 219 and is fixed in the fixing groove 219 by means of a frictional force provided by the fixing groove 219.
In some embodiments, the sliding block 22 slides in the sliding groove 212 along a direction perpendicular to a length direction of the elastic element 23, and the elastic element 23 penetrates the sliding block 22 or the elastic element 23 extends outwardly from two sides of the sliding block 22. Thus, the elastic element 23 exerts a relatively large pressing action on the sliding block 22 when deformed. Specifically, when the elastic element 23 penetrates the sliding block 22, the elastic element 23 is in interference fit with the sliding block 22, such that the elastic element 23 and the sliding block 22 can be fitted tightly. The elastic element 23 can have a columnar or spiral shape.
In some embodiments, the sliding block 22 is located in a middle position in the length direction of the elastic element 23, and a sliding direction of the sliding block 22 within the sliding groove 212 is aligned with a middle position of the card slot 211. Thus, the two sides of the sliding block 22 are under relatively balanced pressing forces from the elastic element 23, thereby preventing the sliding block 22 from coming out of the sliding groove 212 due to unbalanced stress; the sliding direction of the sliding block 22 is aligned with the middle position of the card slot 211, thereby preventing the data card 300 from coming out of the card slot 211 when abutted by the sliding block 22.
In some embodiments, the card holder 20 further includes a handle 24, the handle 24 is coupled to an end of the card tray 21, and the sliding groove 212 is located between the card slot 211 and the handle 24. Specifically, the handle 24 is coupled to the first side wall 213 of the card slot 211, and the handle 24 is substantially perpendicular to the card tray 21, such that the user pushes the card tray 21 into the accommodating space 12 by pushing the handle 24, and meanwhile the handle 24 can be stuck outside the card socket 10 to prevent the whole card holder 20 from being inserted into the accommodating space 12, which otherwise will make it difficult for the card holder 20 to be taken out of the accommodating space 12.
