Connector

Abstract

The invention discloses a connector into which a SIM card is inserted. The connector comprises an insulated body equipped with a receiving chamber, multiple signal terminals and a detecting signal which are held in the insulated body. The elastic arms of the detecting terminal and one signal terminal are received in an opening. The distance between the center of the contact portion of the detecting terminal and the center of the contact portion of one signal terminal is less than or equal to 0.3mm in the width direction of the insulated direction so that the center of the contact portion of the detecting terminal and the center of the contact portion of the one signal terminal are located or substantially located in a straight line in parallel with the length direction of the insulated body. When the SIM card is inserted or pulled out, the contact portion of the detecting terminal is arranged or substantially arranged on the central line of the corresponding metallic pad on the SIM card. Thus, even though the dimension of the SIM card has a large error, the contact portion of the detecting terminal cannot deviate to a plastic groove at the edge of the metallic pad of the SIM card. Accordingly, the connector is suitable for SIM cards with different dimension errors.

Description

technical field [0001] The invention relates to a connector, in particular to a connector for inserting an electronic card, especially a SIM card. Background technique [0002] In the prior art, the connector for inserting an electronic card, especially a mobile phone SIM card, mainly includes an insulating body, a plurality of signal terminals held in the insulating body, a detection terminal held in the insulating body and wrapped in Insulates the outer casing of the body. The detection terminal is used to detect whether the SIM card is inserted into the connector, and the shell provides electromagnetic shielding for the signal terminal and is used to keep the SIM card inserted into the connector in a proper position. [0003] The insulating body has an accommodating cavity for inserting a SIM card, and a plurality of openings are formed on the bottom wall of the accommodating cavity, and the elastic arms of the plurality of signal terminals are respectively accommodated ...

Problems solved by technology

For the detection terminal 30 constructed in this way, if there is an error in the size of the SIM card 500, especially when a large-sized SIM card (such as a 1FF-SIM card and a 2FF-SIM card) is trimmed into a small-sized SIM card (such as a 3FF-SIM card) SIM card and 4FF-SIM card) when using, the contact portion 33 of the detection terminal 30 biased to one side is easily stuck to the groove 511 at the edge of the metal pad 510 of the SIM card 500 (this groove is used In the plastic groove separating each metal pad on the SIM card 500), this will damage the detection terminal 30 and the SIM card 500, causing the connector and the S1M card to fail

[0006] And, if Image 6 As shown, since the wider fixed end 31 of the detection terminal 30 and the wider fixed end 41 of a signal terminal 40 are located on the same side of the opening 11, this will cause the detection terminal 30 and a signal terminal 40 to occupy more space. Large space, not conducive to miniaturization of connector size
