New description: [New technical field] The present invention relates to a connector, and more particularly to a memory card connector having a switch terminal. [Prior Art] According to the development of electronic technology, memory cards have been widely used in digital cameras, personal secretarial assistants (PDAs), mobile phones, jv〇>3, MP4 and other electronic products. These electronic products are usually equipped with a memory card connector to carry the memory card. The 圮fe card connector generally includes an insulative housing, a plurality of signal terminals, and a switch terminal. The signal terminal and the switch terminal are both fixed on the insulating body. However, the connection portion of the switch terminal of the conventional memory card connector and the printed circuit board is planar. When the memory card is inserted and pressed against the contact portion of the switch terminal, the switch has a tolerance due to the thickness of the card. The connection between the terminal and the circuit board is in poor electrical contact, which in turn disables the detection function of the switch terminal. [New Content] The purpose of this creation is to provide a card connector that can effectively prevent the switching function from being invalid due to the thickness tolerance of the card, in view of the defects of the above-mentioned prior art. ° μ In order to achieve the above objectives, the memory card of this creation has an insulated body, a plurality of signal terminals and a switch terminal. The insulative housing has a base of 5 M335840; each signal terminal has a -first fixing portion and an i-th connecting portion and a first connecting portion extending from the first fixing material, the first connecting portion is oriented first The contact portion 'the first fixing portion is fixed to the base portion of the insulating H-contact portion protruding from the insulating body. The switch terminal has a second (four) portion, the second solid portion has a second soldering portion, and the other end of the second retaining portion has a second connecting portion, and the second connecting portion is disposed on the second connecting portion At least a downwardly projecting protrusion, the end of the second connecting portion extends upwardly to a second contact portion, and the connection between the second contact portion and the second connecting portion is provided with a downward protruding (four) rib; The second holding p is on the insulating body. The second contact protrudes from the base of the insulating body. The § memory card connector of the present invention is more sensitive to the contact between the switch terminal and the printed circuit board by the protrusion and the rib on the switch terminal. The switch detection function is disabled due to the memory card thickness tolerance problem. [Embodiment] In order to explain the technical contents, structural features, objectives and effects of the present invention in detail, the embodiments are described below in detail with reference to the drawings. Referring to the first and second figures, the creative memory card connector 丨 includes an insulative housing 10, a terminal set 20, a hook 30 and a housing 40. The insulative housing 10 has a base portion u in the shape of a long rectangular plate. One end of the base portion 11 defines a cutting slot ill extending laterally therethrough and extending through the base portion 11. The other end of the base portion 11 defines a slot 149 for receiving the M335840 slot extending transversely and extending through the base portion 11. . The base portion 11 is on a portion between the cutting groove π ΐ and the accommodating groove 112

The joint of the 23s and the second contact portion 236 is stamped to form a downwardly projecting rib 237. Referring to the third to fifth figures, the terminal group 2 is injection molded on the insulative housing 10, and the holding portion 21 is fixed on a portion of the base u located outside the cutting groove 111; the first of the signal terminals 22 The fixing portion 222 and the second fixing portion 232 of the switch terminal 23 are fixed to a portion of the base portion η between the cutting groove in and the receiving groove 112; the first connecting portion 221 of the signal terminal 22 and the second of the switch terminal 23 The soldering portion 231 is located in the cutting slot 111. The first connecting portion 224 of the signal terminal 22 and the second connecting portion 235 of the switch terminal 23 are located in the receiving slot 112, and the first contact portion 225 and the switch terminal 23 of the signal terminal 22 are The two contact portions 236 project from the base portion 11; the connecting arm portion 234 is partially located in the cutting hole 114. After the terminal group 20 and the insulating body are injection molded together, the connecting arm 234 is cut by the cutting hole I13 by the cutting tool, and the first soldering portion 221 and the opening 8 M335840 closing terminal 23 of the signal terminal 22 are cut by the cutting groove 111. The second soldering portion 231 separates the switch terminal 23 from the corresponding signal terminal 22 and separates the signal terminal 22 and the switch terminal 23 from the holding portion 21. Please continue to refer to the first figure and the second figure, and the hooks 30 are respectively inserted into the first snap groove 13 and the second buckle groove 16. The housing 40 has a substrate 41 and side walls 42 extending vertically downward from both side edges of the substrate 41. A latching arm 421 extends forwardly from the end of the side wall 42. The other end of the side wall 42 is recessed inwardly to form a first convex ridge 422 extending rearwardly of the front Φ and a second convex hull 423. The second convex hull 423 is inserted into the recess 122 of the insulative housing 10 to pivotally connect the housing 4 to the insulative housing 10. The latching arm 421 and the first convex hull 422 are respectively pressed against the engaging plate 12 and the retaining wall 14 of the insulative housing 1 when the housing 40 is fastened to the insulative housing 1b. When a memory card (not shown) is inserted into the memory card connector 1 of the present creation, the bare spot of the memory card abuts against the first contact portion 225 of the signal terminal 22. The memory card presses the contact end 2361 of the switch terminal 23 to cause the projection 2351 of the switch terminal 23 and the rib 237 to press against the printed circuit board, thereby detecting whether the memory card has been fully inserted. In summary, the memory card connector 1 of the present invention makes the contact between the switch terminal ^ and the printed circuit board more sensitive by providing the downwardly protruding protrusion 2351 and the rib 237 on the switch terminal 23. It can effectively prevent the switch extracting function from failing due to the problem of memory card thickness tolerance. In addition, the signal terminal 22 and the switch terminal 23 are extended by the holding portion 21, and the 9 M335840 signal terminal 22 and the switch terminal 23 are connected by a connecting arm 234, so that the signal terminal 22 and the switch terminal 23 can be set. The die is stamped, which reduces costs. [Simple description of the diagram] The first diagram is a three-dimensional combination diagram of the creative memory card connector.
