Description

card connector

technical field

The utility model relates to an electric connector, in particular to a card connector.

Background technique

With the rapid development of electronic technology, SIM cards, SD cards, etc. are widely used in digital products. Since the sizes of the SIM card and the SD card are inconsistent, the SIM card connector and the SD card connector are not compatible with each other, so that the SIM card connector and the SD card connector must be installed on the digital product at the same time. In this way, not only the production cost of the digital product is pushed up, but also the connector interfaces on the digital product are too many, which is not conducive to the convenient use of the user. In order to make the SIM card and SD card suitable for the same card connector, the existing card connectors are generally provided with a card holder, and the card holder is provided with a first card slot for accommodating the SIM card and for accommodating the SIM card. The second card slot of the SD card is accommodated, so that the SIM card and the SD card can be applied to the same card connector. When in use, the card holder is taken out from the card connector, and the SIM card or SD card is placed in the card holder. The side wall of the card connector is provided with an elastic arm, and the free end of the elastic arm is provided with a clamping portion. The side wall of the card seat is provided with a card slot matched with the card holder. During the process of inserting the card holder into the card connector, the clamping portion on the elastic arm first abuts against the side wall of the card holder, and then gradually slides into the card slot. The elasticity of the elastic arm is not enough to rebound and drag the card holder inward when the clamping part slides into the slot. The user must manually push the card socket fully into the card connector by himself. In addition, as the usage time of the card connector increases, the limiting effect of the elastic arm on the card socket will gradually become weaker, thereby making the electrical connection between the card socket and the card connector stable. The performance is weakened, which seriously reduces the user experience.

In view of the above problems, it is necessary to provide a card connector to solve the above problems.

At this time, the card holder 40 will push the matching portion 512 , so that the resisting block 51 rotates, and then drives the pushing rod 52 to reset. At the same time, the first blocking arm 314 will prevent the over-insertion of the card holder 40, and the second blocking arm 315 will prevent the over-rotation of the resisting block 51, thereby protecting the card connector 100. . When it is necessary to take out the card holder 40 , it is only necessary to push the push rod 52 , and the card holder 40 will be pushed out by the resisting portion 511 of the resisting block 51 .

Compared with the prior art, since the card connector 100 of the present invention is provided with a resisting arm 36 and an auxiliary resisting arm 37 resisting the resisting arm 36, the resisting arm 36 and the auxiliary resisting arm 37 face each other. The simply supported structure formed by extension, so that during the process of inserting the card socket 40 into the card connector 100, the auxiliary abutment arm 37 provides a certain reinforcement force for the abutment arm 36, so that the abutment The arm 36 will bounce back when the holding portion just extends into the slot 442 of the card holder 40 and drag the card holder 40 inward, so that the user feels that the card holder 40 is sucked into the card connection. In the card connector 100, the user experience is improved, and at the same time, the clamping with the card holder 40 can be strengthened to ensure the stability of the card connector 100 in use.

In particular, it should be pointed out that for those skilled in the art, the equivalent changes made under the teaching of the utility model for the utility model should still be included in the claimed scope of the utility model patent scope.
