Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
In the present embodiment, the structure of card class connector as shown in Figure 1, comprises plastic body 1, some shielding casings 3 that is housed in conducting terminal 2 in plastic body 1, covers at plastic body 1 top.In the present embodiment, in card class connector, the state of each parts is not called conventional state when inserting electronic cards 4.
The slot 11 that is provided with electronic cards such as accommodating MS card (Memory Stick card) or SD card (Secure Digital card) in plastic body 1, the both sides of slot 11 are provided with guide rail, and electronic cards can be slided before and after guide rail.Conducting terminal 2 has and protrudes into the contact site 21 in order to coordinate with electronic cards in slot 11.
In plastic body 1, the rear end of slot 11 is provided with an elastic construction, this elastic construction is specially a shell fragment 12, shell fragment 12 comprises the fixed part 121 and 123 that is positioned at middle force section 122, is positioned at both sides, the fixed part 121 and 123 of both sides stretches in plastic body 1, and force section 122 protrudes in described slot 11.The front end both sides of slot 11 are respectively equipped with a mounting groove 13, are equiped with a fixed leg, a grab 14 and a torsionspring 15 in mounting groove 13.Grab 14 is comprised of articulated section 141 and buckling parts 142, and articulated section 141 is articulated in a fixed leg by torsionspring 15, and buckling parts 142 part under conventional state protrudes in slot 11.
On the side of shielding casing 3, at the positive front end of each mounting groove 13, be provided with a through hole 31.In through hole 31, be equipped with an operating portion 32, operating portion 32 can horizontally slip under extraneous active force in through hole 31; On operating portion 32, be fixed with a pushing portion 33, under conventional state, pushing portion 33 stretches in corresponding mounting groove 13 and touches with the bottom connection of buckling parts 142.When operating portion 32 slides laterally, pushing portion 33 buckling parts 142 to grab 14 under the drive of operating portion 32 applies active force laterally, until buckling parts 142 is accommodated in mounting groove 13 completely.
The structure of electronic cards 4 as shown in Figure 2, offers respectively a recess 41 on its dual-side, the buckling parts 142 of above-mentioned grab 14 is suitable with recess 41.
