DETAILED DESCRIPTION

(12) While the Present Disclosure may be susceptible to embodiment in different forms, there is shown in the Figures, and will be described herein in detail, specific embodiments, with the understanding that the Present Disclosure is to be considered an exemplification of the principles of the Present Disclosure, and is not intended to limit the Present Disclosure to that as illustrated.

(13) As such, references to a feature or aspect are intended to describe a feature or aspect of an example of the Present Disclosure, not to imply that every embodiment thereof must have the described feature or aspect. Furthermore, it should be noted that the description illustrates a number of features. While certain features have been combined together to illustrate potential system designs, those features may also be used in other combinations not expressly disclosed. Thus, the depicted combinations are not intended to be limiting, unless otherwise noted.

(14) In the embodiments illustrated in the Figures, representations of directions such as up, down, left, right, front and rear, forward and rearward, used for explaining the structure and movement of the various elements of the Present Disclosure, are not absolute, but relative. These representations are appropriate when the elements are in the position shown in the Figures.

(15) Referring to FIGS. 1-2, the puller type card socket of the Present Disclosure comprises a housing 10, cover 20 and puller 30. In the housing 10, a card insertion space is formed of an insulating material, into the top part of which a card is inserted; this card insertion space is covered by the cover 20. On the bottom surface of the card insertion space of the housing 10, contact terminals 40 are formed that contact the card 1.

(16) The cover 20 is joined to either side of the housing 10, and covers the card insertion space and the contact terminals 40. On the cover 20, a card pushing part 21, which pushes the inserted card 1 downward to maintain stable contact between the card 1 and the contact terminals 40 and prevents the card 1 from slipping out when inserted, is formed as a single unit by bending. The card pushing part 21 is bent in the same direction in which the card 1 is inserted, which facilitates card insertion.

(17) The puller 30 is mounted slidably on one side of the housing 10 so that the card 1 can be readily withdrawn from the front. The puller 30 is furnished so as to slide in the card's insertion and withdrawal directions, so that when withdrawing the card 1, if the user pulls forcibly on the puller 30 in the withdrawal direction, the puller 30 forcibly withdraws the card 1 by pulling it in the withdrawal direction. When the card 1 is inserted, the puller 30 is slid in the card insertion direction by the action of inserting the card 1.

(18) Referring to FIGS. 3-6, on one side of the card insertion space of the housing 10, a sliding groove 11 is formed in the front-to-back direction, along which the puller 30 is inserted so as to be able to slide in the front-to-back direction. On one side of the rear end of the card insertion space, a sloped face is furnished corresponding to the sloped face formed on the front end of the card 1, so as to form a reverse mounting prevention part 12 that prevents the reverse mounting of the card 1. The reverse mounting prevention part 12 is formed in a triangular shape when viewed from above.

(19) The puller 30 comprises a sliding part 31 having a flat shape that is inserted slidably into the sliding groove 11; a card contact part 32 that extends laterally from upper side of the rear end of the sliding part 31 so as to be pushed by the card 1 when the card 1 is inserted, and pushes the card 1 in the card withdrawal direction when the card 1 is withdrawn; and a pulling part 33 that is bent laterally from the front end of the sliding part 31 so as to enable the user to pull it when withdrawing the card 1. The pulling part 33 may also be formed by bending the front end of the sliding part 31 upward or downward, instead of laterally.

(20) The card contact part 32 contacts the sloped front surface of the card 1 when the card 1 is inserted and withdrawn. It has a sloped face 32a that contacts the sloped front end of the card 1, formed at a slope corresponding to the sloped front end of the card 1. This card contact part 32 is formed in a shape corresponding overall to the reverse mounting prevention part 12 when viewed from above. When the card 1 has been fully inserted, it overlaps with the reverse mounting prevention part 12 while covering the reverse mounting prevention part 12. On part of the sloped face 32a of the card contact part 32, a contact area expansion part 32b is formed that expands the area of contact with the card 1.

(21) The card contact part 32 is formed by bending the top of the rear end of the sliding part 31 laterally and horizontally. The contact area expansion part 32b is formed by bending part of the sloped face 32a of the card contact part 32 vertically downward. Bending grooves 31a, 32c are formed respectively on the rear end of the sliding part 31 and the sloped face 32a of the card contact part 32 to facilitate the bending of the card contact part 32 and contact area expansion part 32b. On the reverse mounting prevention part 12 of the housing 10, an overlapping lip 12a is formed so as to overlap the contact area expansion part 32b of the card contact part 32, so that the sloped face of the reverse mounting prevention part 12 will match the sloped face 32a of the card contact part 32.

(22) The puller 30 is covered by the cover 20 so as to prevent detachment upward. Forward movement is restricted by the stopper part 13 formed on the sliding groove 11. Specifically, at a certain location on the sliding groove 11, a stopper part 13 having a tab shape is formed on the top of one side wall of the sliding groove 11, in order to prevent the complete detachment of the puller 30 from the front of the housing 10 when the card is being withdrawn by pulling the puller 30 forward. The card contact part 32 of the puller 30 catches on the stopper part 13 so as to restrict forward sliding.

(23) Referring to FIGS. 7-8, when the card 1 is pushed into the card insertion space formed in the housing 10, the puller 30 is pushed by the front end of the card 1 and slid into the card insertion space. When the card 1 has been fully inserted, the sloped front end of the card 1 contacts the sloped face of the reverse mounting prevention part 12 within the card insertion space. If the sloped front end of the card 1 does not contact the sloped face of the reverse mounting prevention part 12, the insertion direction of the card 1 is incorrect and therefore the card 1 is reversed and re-inserted.

(24) If the card 1 is properly fully inserted, the card contact part 32 of the puller 30 overlaps with the reverse mounting prevention part 12 and the sloped surface of the reverse mounting prevention part 12 and the sloped surface of the card contact part 32 both simultaneously contact the sloped front end of the card 1. When the card 1 has been completely inserted, the pulling part 33 of the puller 30 catches on the front end of the housing 10, restricting further insertion. Accordingly, the pulling part 33 of the puller 30 is pulled when the card 1 is withdrawn. When the pulling part 33 of the puller 30 is pulled forward in order to withdraw the card 1, the card contact part 32 of the puller 30 is moved forward, and the front end of the card 1 is pushed in the withdrawal direction. When the card 1 has been withdrawn to some degree, the card contact part 32 of the puller 30 catches on the stopper part 13 formed on the sliding groove 11 of the housing 10, and consequently forward sliding of the puller 30 is restricted. The card 1 that has been withdrawn to some extent can then be grasped by the user's hand or other tool and withdrawn fully.

(25) Referring to FIGS. 9-10, even in a set in which the top surface of the socket is entirely blocked by the set and only the front part into which the card 1 is inserted is open, the insertion and withdrawal of the card 1 is facilitated using the puller 30.

(26) A preferred embodiment of the Present Disclosure was described in detail above. However, the Present Disclosure is not limited to the embodiment described above. Various modifications and improvements are possible within the spirit of Present Disclosure described in the claims.
