Hereinafter, a first card C1 and a second card C2 can be distinguished as different heterogeneous cards.
FIG. 1 illustrates a state in which different-sized cards are coupled to a socket according to various embodiments of the present disclosure. Although it is illustrated herein that two cards having different sizes are coupled to the socket, this is only to illustrate that the two cards can be both coupled to one socket. According to the present disclosure, it is preferable that any one of the two cards is selectively contained in or otherwise coupled to the socket.
Referring to FIG. 1, a battery pack 103 can be coupled to a rear surface 101 of an electronic device 100, and a socket 1 may be coupled to an upper portion thereof. As will be described in more detail below, the socket 1 has a card containing space and may contain different cards, i.e., a first card C1 and a second card C2, in the same containing space. The electronic device 100 may include a battery cover 110, which covers the socket 1 and the battery pack 103 and which constitutes an exterior of the electronic device 100. The battery cover 110 may be coupled to a battery attachment surface 102 of the electronic device 100.
According to various embodiments, the socket 1 may include a first tension rib 21 and a second tension rib 22 which are disposed to maintain a tension in a direction of the card containing space in an upper surface of the socket 1. The first card C1 is guided by a guide sidewall of the second tension rib 22, and may be disposed in a space formed by the second tension rib 22. In this case, the first card C1 is pressingly supported by the first tension rib 21, so as not to be pushed backward. Alternatively, the first card C1 may be removed from the socket 1, and the second card C2 may be disposed in the card containing space of the socket 1. In this case, the second card C2 may be pressingly supported by the first tension rib 21 and the second tension rib 22.
FIG. 2 is a perspective view of a socket according to an embodiment of the present disclosure.
Referring to FIG. 2, a socket 1 may include a socket housing 10 having a card containing space 30 and including a plurality of protrusion nodes disposed inside the card containing space 30 and a socket cover 20 coupled to an upper portion of the socket housing 10 and pressingly supporting an upper portion of a coupled card. According to an embodiment, the socket 1 is disposed in a proper location inside the electronic device 100, and may be mounted on a board (i.e., a Printed Circuit Board (PCB)) in a Surface Mounted Device (SMD) manner. According to an embodiment, the socket 1 may be disposed in a proper location in the electronic device 100, not on the board. According to an embodiment, the socket 1 may be coupled to a case frame of the electronic device 100, and may be disposed in a location corresponding to a slot having a specific length for inserting the card.
The socket housing 10 may be formed of a synthetic resin material, such as by a molding process, and the socket cover 20 may be fixed to the socket housing 10, for example by using insert molding. The socket cover 20 may be formed with a metal plate, and may be installed in such a manner that a card coupled to the socket housing 10 is completely or partially covered. The socket cover 20 may be disposed to maintain a tension in a direction of the card containing space, and may include a first tension rib 21 and a second tension rib 22 to pressingly support the coupled card. In addition, an upper portion of the socket cover 20 may include one or more auxiliary tension ribs 23 protruding towards the card containing space 30 and pressingly supporting the coupled card together with the first tension rib 21 and the second tension rib 22.
The first tension rib 21 may be extended in a lengthwise direction in an upper surface of the socket cover 20, and may be disposed to maintain a tension in a direction of the card containing space. The first tension rib 21 may include a sidewall 211 on an outer peripheral edge thereof. The first tension rib 21 may be separated by a specific interval from the second tension rib 22, and may be disposed in a first space 221 formed by the second tension rib 22. If a first card C1 is inserted, the first space 221 may be applied as a space in which the first card C1 may move upward by pushing up the first tension rib 21. The second tension rib 22 may be disposed in the card containing space 30 in the upper surface of the socket cover 20 to maintain a tension, and may be formed in an open box or a staple shape (e.g., ‘⊂’).
The second tension rib 22 may include a first guide sidewall 224 extended from the socket cover 20 to the card containing space 30, a second guide sidewall 225 facing the first guide sidewall 224, a hindrance portion 223 connecting the first guide sidewall 224 and the second guide sidewall 225, and a third sidewall 226 on an outer peripheral edge thereof. Herein, the first guide sidewall 224 may be separated from the second guide sidewall 225 by a width w of the first card C1. The hindrance portion 223 may be formed with a specific thickness, and may hinder the first C1 from crossing the hindrance portion 223. In addition, if a second card C2 is inserted, the second tension rib 22 may move upward through a second space 222 towards the upper surface of the socket cover 20 by the insertion of the second card C2.
According to the present disclosure, a guide groove 24 may be further formed in the socket housing 10 in a portion where the card containing space 30 begins. The guide groove 24 may assist in properly guiding insertion of the first card C1 having a size less than a width of the card containing space 30. The first card C1 may also be guided by the guide sidewalls 224 and 225 of the second tension rib 22 protruding from the socket cover 20 in a direction of the card containing space, and may be disposed towards the first space 221 by being hindered by the hindrance portion 223 to avoid an excessive insertion. If the first card C1 pushes up the first tension rib 21, the first tension rib 21 presses down the upper surface of the coupled first card C1 at a specific tension, and thus may prevent the first card C1 from being detached from the socket housing 10.
According to an embodiment, the second card C2 may have a size corresponding to a size of the card containing space 30 of the socket housing 10. In this case, the second card C2 may be correctly inserted into the card containing space 30 without an additional guide means. The second card C2 pushes up the first tension rib 21 and second tension rib 22 protruding towards the card containing space 30 simultaneously from the socket cover 20, and is supported by a tension in a downward direction of the first tension rib 21 and the second tension rib 22, thereby being able to prevent the second card C2 from being detached from the socket housing 10.
In general, even if the cards C1 and C2 to be coupled to the socket 1 are fully coupled to the socket 1, the cards may be partially exposed to the outside rather than being fully inserted into the socket housing 10. This is to allow a user to be able to easily separate the cards C1 and C2. Therefore, the cards C1 and C2 may be detached or removed from the card containing space 30 when an exposed portion of the cards C1 and C2 is pulled with a specific tension in a state where the cards C1 and C2 are fully coupled to the socket housing 10.
According to various embodiments, the socket 1 may be formed integrally rather than in a structure in which the socket housing 10 and the socket cover 20 are separated. In this case, the socket 1 is preferably formed with a metal material, and may be formed together with the first tension rib 21 and the second tension rib 22 through a process such as pressing, etc.
