Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

As shown in fig. 1-5, the chip card socket according to the present embodiment includes a metal outer shell 1, a card ejecting mechanism, a contact terminal 2 for connecting with an external controller, and an insulating inner shell 3 for accommodating a chip; the metal outer shell 1 is sleeved outside the insulating inner shell 3; the contact terminal 2 is arranged on the inner wall of the insulating inner shell 3; the card withdrawing mechanism comprises a rotating shaft 4, a rotating rod 5 used for withdrawing the chip from the insulating inner shell 3 and a push rod 6 used for enabling the rotating rod 5 to swing along the rotating shaft 4; the push rod 6 is connected with the metal shell 1 in a sliding manner; the rotating rod 5 is hinged with the insulating inner shell 3 through the rotating shaft 4; the push rod 6 is used for pushing one end of the rotating rod 5; the other end of the rotating rod 5 is used for abutting against the chip.

Specifically, the contact terminal 2 has a plurality of contact nodes thereon, and the contact nodes are electrically connected to an external controller, respectively, so that the external controller can communicate data with the chip.

During operation, dwang 5 is located the innermost side along the plug-in card direction on insulating inner shell 3, and along with the chip slowly inserts, one side of chip finally can support with the other end of dwang 5 and lean on to chip on the chip will realize communication connection with a plurality of contact terminal 2 contacts. When the card needs to be withdrawn, the push rod 6 only needs to be pushed inwards, and along with the movement of the push rod 6, the rotating rod 5 connected with one end of the push rod 6 can be driven to swing along the rotating shaft 4. Since one side of the chip abuts against the other end of the rotating rod 5, the rotating rod 5 will push the chip when swinging, and the chip can exit the inner insulating housing 3.

As shown in fig. 1-5, in the chip card socket of this embodiment, one end of the push rod 6 is provided with a slot 63; one end of the rotating rod 5 is provided with a hook part 51 matched with the notch 63; the slot 63 is movably connected with the hook part 51.

When the card needs to be withdrawn, only the other end of the push rod 6 needs to be pushed, and in the process that the push rod 6 slides along the metal shell 1, the hook part 51 is driven to move backwards along with the push rod, so that the other end of the rotating rod 5 can push out the chip. In addition, a certain gap is formed between the hook part 51 and the slot 63, so that the push rod 6 can move smoothly when moving forwards and backwards.

As shown in fig. 1-5, in the chip card socket according to this embodiment, an inclined portion 52 is further disposed at one end of the rotating rod 5; the hook 51 is attached to the inclined portion 52.

Specifically, in order to achieve a larger card ejecting stroke in a limited space, the length of the push rod 6 can be reduced, and therefore, the inclined portion 52 is provided on the rotating lever 5, so that the rotating lever 5 can be normally movably connected with the shorter push rod 6.

As shown in fig. 1-5, in the chip card socket according to this embodiment, a push block portion 61 is disposed at the other end of the push rod 6; the outer side of the push block part 61 is provided with a positioning groove 62 which is convenient for pushing the push rod 6.

The provision of the positioning groove 62 prevents slippage when the push rod 6 is pushed inward.

As shown in fig. 1-5, in the chip card socket according to this embodiment, the chip card socket further includes an in-place detection terminal 7 for detecting an in-place condition of a chip; the in-place detection terminal 7 is mounted on the insulating inner shell 3; one end of the in-place detection terminal 7 is electrically connected with an external controller; the other end of the in-place detection terminal 7 is movably connected with the contact terminal 2.

Specifically, the in-place detection terminal 7 is entirely made of a metal material, and the in-place detection terminal 7 has a certain elasticity. After the chip is inserted, the in-place detection terminal 7 is switched from the original state of keeping contact with the contact terminal 2 to the state of being separated from the contact terminal 2, and then the external controller can recognize the jump action and judge that the current chip is inserted in place; when the chip is pulled out, the in-place detection terminal 7 is reset under the action of elastic force, and the state originally separated from the contact terminal 2 is changed into the state of keeping contact, so that the external controller recognizes the jump action and judges that the current chip is in the pulled-out state.

As shown in fig. 1 to 5, in the chip card socket according to this embodiment, the in-place detection terminal 7 includes a mounting portion 71, a bending portion 72, a first contact portion 73 for electrically connecting with an external controller, and a second contact portion 74 for movably connecting with the contact terminal 2; the mounting portion 71 is mounted on the insulating inner housing 3; the bending part 72 is connected with the mounting part 71; the first contact portion 73 is connected to the mounting portion 71; the second contact portion 74 is connected to the bent portion 72.

Specifically, the provision of the bent portion 72 ensures the elasticity of the in-place detection terminal 7, and the elasticity is not easily reduced as the number of times of use increases; by disposing the second contact portion 74 on the bent portion 72, the second contact portion 74 can be effectively driven to be away from or contact the contact terminal 2.

As shown in fig. 1-5, in the chip card socket according to this embodiment, the metal shell 1 includes a bottom plate 11, an inner baffle 12, and two side plates 13 respectively disposed on two sides of the bottom plate 11; the insulating inner shell 3 is arranged on the bottom plate 11; the inner baffle plate 12 is connected with the bottom plate 11; the inner baffle 12 is arranged on the inner side of any one side plate 13; a sliding groove 14 for the sliding connection of the push rod 6 is formed between the inner baffle plate 12 and the side plate 13.

In particular, to achieve a greater ejection stroke in a limited space, the length of the push rod 6 will be significantly shorter than the length of the chute 14. The sliding direction of the push rod 6 can be limited by arranging the inner baffle 12, so that the push rod 6 and the sliding chute 14 can slide stably.

The above is only a preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles in accordance with the claims of the present invention are included in the protection scope of the present invention.
