A switch terminal on one side of the body, the switch terminal being composed of three terminals. In the prior art, the switch terminals of the card connector are mounted on the side of the card connector, so that the width of the card connector is large, and thus the mounting surface of the external device is occupied, and the switch terminal is composed of three independent terminals, thereby Three molds are required for manufacturing, and there are many assembly programs, which increases production costs. Therefore, it is necessary to improve the existing technology to overcome the above drawbacks. [New content] The technical problem to be solved by this creative is to provide a card connector with a small width and a low production cost. In order to solve the above problems, the present invention provides a card connector for inserting an electronic card, which comprises an insulating base, a metal case covered on the insulating base, and a signal terminal fixed on the insulating base, the metal shell The body and the insulating base form a receiving space, the receiving space is provided with an opening for inserting an electronic card, the card connector further comprises a switch terminal, and the switch terminal comprises a first detecting terminal mounted on the insulating base And forming a second detecting terminal on the metal casing, wherein the first detecting terminal is disposed on a side of the signal terminal away from the opening. Compared with the prior art, the creative card connector has the first detecting terminal disposed on one side of the signal terminal away from the opening, thereby reducing the width of the card connector, and the second detecting terminal is disposed on the metal casing. This reduces the number of molds and, in turn, 3 M378533 reduces production costs. The present invention will be further described below in conjunction with the drawings and embodiments. [Embodiment] Referring to the first to fifth figures, a card connector 100 according to the present invention includes an insulating base 10, a metal case 20 wrapped around the insulating base 10, and held in the insulating base 10.

The metal casing 20 includes a top wall 21 extending from the opposite sides of the top wall 21 in parallel with one side to the side wall 22 and from the other side of the top wall 21 to the rear wall 23. The metal casing 20 is engaged with the insulating base 10 to form a receiving space 25 having an opening 24 into which an electronic card (not shown) can be inserted. The top wall 21 is provided with a second detecting terminal 211 extending obliquely into the card connector 100. The second detecting terminal 211 includes a connecting portion 212 extending from the metal housing 20 in the insertion direction of the electronic card. The connecting portion 212 extends obliquely toward the inside of the card connector 100, and the contact arm 214 continues to extend from the inclined portion 213. In the embodiment, the second detecting terminal 211 is a spring piece structure, and the metal casing 20 is provided with a pair of second detecting terminals 211. The signal terminal 30 is fixed in the mounting portion 13 of the insulating base 10. The signal terminal 30 includes an abutting portion 31 electrically connected to the electronic card, and a holding portion 32 fixed to the mounting portion 13 of the insulating base 10. Solder pins 33 that can be soldered to the board. The first detecting terminal 40 is mounted in a slot 111 on the insulating base 10 in an elongated shape, so that the first detecting terminal 40 is located on one side of the signal terminal 30 away from the opening 24, and thus the switch terminal is compared The width of the electronic card connector 100 is reduced in the case where the side 4 M378533 of the insulating base 10 is mounted. The first detecting terminal 40 and the second detecting terminal 211 form a switch terminal, and the second detecting terminal 211 is elastically abutted against the first detecting terminal 40. The first detecting terminal 40 includes a second detecting terminal.

The contact portion 41 is provided with a bump 411, and the bump 411 is in electrical contact with the contact arm 214 on the second detecting terminal 211. When the electronic card is not inserted into the card connector, the second detecting terminal 211 is electrically connected to the bump 411 on the contact portion 41. When the electronic card is inserted, the electronic card gradually changes the second detecting terminal 211 outward. When the electronic card continues to be inserted inward, the contact arm 214 of the second detecting terminal 211 is electrically disconnected from the bump 411, so that the electronic card is inserted into the card connector 100. The card ejecting mechanism 50 is mounted on one side arm 12 of the insulating base 10. The card ejecting mechanism 50 includes an insulating block 51, an elastic member 52 received in the insulating block 51, and a slide bar mounted on the insulating block 51. 53 and terminal 54.
