Problems solved by technology

[0004] However, for the card connector whose contact end of the conductive terminal is designed as a protruding arc, when the card is inserted, when the electronic card presses the contact end of the conductive terminal downward, the contact end will preferentially interfere with the PCB board, causing the card not to be installed. The contact end has been abutted to the PCB board when it is in place, so that the card cannot be plugged in due to simple support

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 and figure 2 As shown, the card connector 100 of the present invention is used to insert an electronic card (in this embodiment, a SIM card). The card connector 100 includes an insulating body 10 , a plurality of conductive terminals 20 installed in the insulating body 10 , and a shielding shell 30 covering the outer side of the insulating body 10 .

[0027] Such as image 3 and combine figure 2 As shown, the insulating body 10 is provided with a housing cavity 11 for accommodating the electronic card and a terminal groove 12 for accommodating the conductive terminals 20, the terminal groove 12 penetrates the insulating body 10 up and down and is connected with the The accommodating cavity 11 is connected to facilitat...

Abstract

The invention provides a card connector, which comprises an insulation body and a conductive terminal which is arranged in the insulation body. The insulation body is provided with a terminal groove; the conductive terminal is provided with an elastic arm which is contained in the terminal groove, a contact part which extends out of the terminal groove so as to be contacted with an electronic card, and a guide part which is used for connecting the contact part with the elastic arm; the contact part is positioned above the middle of the terminal groove; the guide part extends from the contact part to the two sides of the terminal groove and extends into the terminal groove, and the lower end surface of the guide part is not higher than the terminal groove; in the horizontal direction, a connecting line between the initial contact point where the electronic card and the guide part are contacted for the first time and the tiptop of the contact part is not parallel to the insertion direction of the electronic card.

Description

technical field [0001] The present invention relates to a card connector. Background technique [0002] Existing card connectors for receiving electronic cards usually include an insulating body, a number of conductive terminals held on the insulating body, and a shielding shell covering the insulating body. containment space. [0003] The conductive terminals of most existing card connectors are designed in a thin strip shape, but the contact end faces are changed in different shapes. For example: design the contact end of the conductive terminal into a protruding arc shape to facilitate the insertion and withdrawal of the electronic card; design the conductive terminal so that the tail is inclined upwards, and the end is horizontally flat, etc. [0004] However, for the card connector whose contact end of the conductive terminal is designed as a protruding arc, when the card is inserted, when the electronic card presses the contact end of the conductive terminal downward...
