1. Field of the Invention
The present invention relates to electrical card connectors, more particularly to an electrical card connector with an improved metallic cover for preventing an aslant-inserted electrical card.
2. Description of Related Art
Chinese Patent CN 202585910, issued on Dec. 5, 2012, discloses an electrical card connector, which comprises an insulative housing, a plurality of contacts received in the insulative housing and a metallic cover covering the insulative housing. The metallic cover has a top wall upon a cavity defined by the insulative housing and the metallic cover for receiving an electrical card. The top wall is formed with a plurality of openings corresponding to contacting portions of the contacts and two elastic fingers besides the opening to press the inserted card. However, when the electrical card inserts, it is easy to incline and then brush the contacting portions of the contacts, and the contact may be destroyed after being used for a long time.
Hence, an improved electrical connector is desired to overcome the above problems.
According to one aspect of the present invention, an electrical connector, for receiving an electrical card, comprises an insulative housing with a bottom wall, a metallic cover covering the insulative housing to define a receiving cavity, and a plurality of contacts retained to the insulative housing and extending into the receiving cavity. The shell has a top plate, which defines a plurality of openings, a plurality of resisting pieces bent downwardly from front edges of the openings, and a plurality of gaps defined between each two adjacent resisting pieces. Each contact has a conductive portion, and the conductive portions and the gaps of the top plate are alternatively disposed.
The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter which form the subject of the claims of the invention.
For a more complete understanding of the present invention, and the advantages thereof, reference is now made to the following descriptions taken in conjunction with the accompanying drawings, in which:
In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention. However, it will be obvious to those skilled in the art that the present invention may be practiced without such specific details. In other instances, well-known circuits have been shown in block diagram form in order not to obscure the present invention in unnecessary detail. For the most part, details concerning timing considerations and the like have been omitted inasmuch as such details are not necessary to obtain a complete understanding of the present invention and are within the skills of persons of ordinary skill in the relevant art.
Reference will be made to the drawing figures to describe the present invention in detail, wherein depicted elements are not necessarily shown to scale and wherein like or similar elements are designated by same or similar reference numeral through the several views and same or similar terminology.

The bottom wall of the guiding slot 110 is a part of the bottom wall 10 of the insulative housing 1. The guiding slot 110 further has a perpendicular inner side surface 111 connecting a top wall thereof and a bottom wall thereof, the slot 120 passes through the inner side surface 111 to communicate with the receiving cavity 6, and make a part of the top wall of the guiding slot 110 be a transverse arm 121 bestriding the guiding slot 110, the transverse arm 121 has a protrusion 123 on the top thereof to engage with the metallic cover 2. The transverse arm 121 has a resisting face 1211 on an outside vertical side and a clump 1210 protruding into the slot 120 from the resisting face 1211. The first side wall 12 and the second side wall 13 are formed with a plurality of latching ribs 113 for latching with the metallic cover 2. The latching ribs 113 are located on a front and a rear ends of the first side wall 12 and the second side wall 13.

The conductive contact 3 has a fixing portion 33 mounted in the retaining slots 141, a soldering leg 34 extending from the fixing portion 33 and beyond the mounting wall 14, an extending portion 32 extending forwardly from the fixing portion 33 and an arch elastic conductive portion 31 extending forwardly from the extending portion 32 and protruding toward the bottom wall 10, the conductive portions 31 are arranged in a row along a width direction of the insulative housing 1 and substantially located on the upper side of the receiving cavity 6. The fixing portion 33 has a plurality of barbs 331 on two sides thereof to interferes with inner walls of the retaining slots 141.
The first detect pin 4 has a first mounting portion 43 perpendicular mounted in the first mounting hole 122, a first retaining portion 42 extending from the first mounting portion 43, an arch first elastic contacting portion 41 extending from the first retaining portion 42 to the receiving cavity 6, and a first soldering portion 44 extending rearward from the first mounting portion 43. The second detect pin 5 has a second mounting portion 53 perpendicular mounted in the second mounting hole 131, a second retaining portion 52 extending from the second mounting portion 53, an arch second elastic contacting portion 51 extending from the second retaining portion 52 to the receiving cavity 6, and a second soldering portion 54 extending rearward from the second mounting portion 53. The first soldering portion 44, the second soldering portion 54 and the soldering legs 34 of the conductive legs 3 are arranged in a same row and are coplanar with each other.

The second sidewall 23 is torn to form a second elastic piece 25 from the middle thereof. The first elastic arm 24 and the first detect pin 4 are used to indicate whether the electrical card 200 is in a write protecting status. The second elastic arm 25 and the second detect pin 5 are used to indicate whether the electrical card 200 is inserted into the electrical card connector 100. The top plate 21 has a through notch 28 to engage with the protrusion 123 of the transverse arm 121 to strengthen the transverse arm 121. The first sidewall 22 and the second sidewall 23 further have a plurality of latching openings 27 latching with the latching ribs 113 of the insulative housing 1.
The top plate 21 has a plurality of openings 211 and a plurality of resisting or aligning pieces 212 formed by tearing and extending from an edge of the opening 211 into the receiving cavity 6. The openings 211 are over corresponding conductive contacts 3, and the resisting pieces 212 are located above and in a front of the conductive contacts 3.
The resisting pieces 212 extend downwardly, and are lower than free ends 30 of the contacts 3 along a vertical direction, so that the electrical card 200 will not enter into a room between the free ends 30 and the resisting pieces 212 that may destroy the conductive contacts 3. There are some gaps 213 between two adjacent resisting pieces 212, and the gaps 213 and the conductive contacts 3 are alternately disposed along the width direction of the electrical card connector 100.
