Embodiment Construction
[0042] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings. In the specification, the same or similar reference numerals designate the same or similar components. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the general inventive concept of the present invention, but should not be construed as a limitation of the present invention.
[0043] According to a general technical idea of the present invention, there is provided a card connector for inserting an electronic card, the card connector comprising: a base; and a plurality of terminals arranged on the base. Each of the terminals includes: a contact portion for making electrical contact with the inserted electronic card; and a pair of elastic arms respectively extending from the base and intersecting the contact portion...

The invention discloses a card connector used for plugging an electronic card. The card connector comprises a base and multiple terminals, wherein each terminal comprises a contact part used for being in contact with the plugged electronic card, and a pair of elastic arms; the elastic arms extend from the base separately and are crossed in the corresponding contact part; the pair of elastic arms are suitable for enabling the corresponding contact part to perform elastic displacement in an up-and-down direction; a smooth surface extending to the contact part is formed on each elastic arm; the pair of elastic arms are positioned parallel with the plugging direction of the electronic card, and pass through the two sides of the vertical surface of the corresponding contact part, so that when the electronic card is plugged, the electronic card and the smooth surfaces of the elastic arms are in sliding contact. Therefore, when the electronic card is plugged, the electronic card slides to or leaves the corresponding contact part under the guide of the smooth surfaces of the elastic arms, so that the contact between the electronic card and the sharp outer side edges of the elastic arms is avoided; the abrasion of the electronic card caused by the edges of the terminals is prevented; and the service life of the electronic card is prolonged.
Description
technical field [0001] The invention relates to a card connector for plugging in an electronic card, in particular to a card connector which can prevent the electronic card from being worn by the terminals of the card connector when plugging and pulling out. Background technique [0002] In the prior art, a card connector generally includes a base and a plurality of terminals held in the base, and each terminal has a contact portion at the top end for making electrical contact with an inserted electronic card. [0003] In the prior art, there are two ways of plugging and unplugging electronic cards: one is vertical insertion, that is, the electronic card is inserted into the connector or pulled out from the connector along its longitudinal direction; the other is horizontal insertion, that is, the electronic card is inserted along the It is plugged into or unplugged from the connector in a lateral orientation. In the connector suitable for inserting the electronic card hori...
