CARD TRAY HAVING INSULATIVE LATCHING PROTRUSION AND METALLIC REINFORCING PORTION EMBEDDED IN THE PROTRUSION
The present invention relates to a card tray including insert molded insulative frame and metallic plate so structured and arranged that latching protrusions thereof are protected from being damaged. Taiwan Patent No. M483573 discloses a card tray including an insulative frame having a side recess and a metallic plate molded with the insulative frame, wherein the metallic plate has a latching protrusion exposed to the side recess. A card tray comprises an insulative frame having a side recess and a protrusion in front of the side recess; and a metallic plate molded with the insulative frame, the metallic plate having a reinforcing portion embedded in the insulative frame, wherein the protrusion has an end face at a lateral side thereof, and the reinforcing portion has an upper and lower edges buried in the protrusion and an exposed end face flush with the end face of the protrusion. Referring to The insulative frame 1 includes a pair of side beams 11 and a front and rear beams 12 and has a top and bottom faces 13 and 14. The rear beam 12 has a face plate 121. The side beam 11 has a recess 111 for engaging a corresponding latch of the electrical connector and a protrusion 112 in front of the recess 111. The metallic plate 2 includes a main part 21 and a pair of reinforcing portions 22 embedded in the side beams 11 of the insulative frame 1. The protrusion 112 has an end face at a lateral side thereof. The reinforcing portion 22 extending parallel to has an upper and lower edges buried in the protrusion 112 and an exposed end face flush with the end face of the protrusion 112. The reinforcing portion 22 includes a base 221 and three fingers 222 divided by slots 2220. The base 221 has a hole 2210. All the slots 2220 and the hole 2210 are filled by plastic materials during molding. The buried fingers 222 with only end faces thereof exposed to outside not only strengthen the protrusion 112 but also make the combined structure of the fingers 222 and the protrusion 112 sturdy and durable, compared with the mere blade type reinforcing portion. The metallic plate has a pair of side walls 212 bent at edges 211 of a horizontal plate (not labeled) and the reinforcing portion 22 integrally extends from a bottom of the side wall 212, by suitable machining operations such as punching and bending, to leave an opening 210. Therefore, the dimension of the opening 210 in the transverse direction is not less than that of the reinforcing portion 22. The reinforcing portion 22 extends horizontally parallel to the horizontal plate in an offset higher level in the vertical direction, as shown in A card tray includes: an insulative frame having a side recess and a protrusion in front of the side recess; and a metallic plate molded with the insulative frame, the metallic plate having a reinforcing portion embedded in the insulative frame; wherein the protrusion has an end face at a lateral side thereof, and the reinforcing portion has an upper and lower edges buried in the protrusion and an exposed end face flush with the end face of the protrusion. 1. A card tray comprising:
an insulative frame having a side recess and a protrusion in front of the side recess; and a metallic plate molded with the insulative frame, the metallic plate having a reinforcing portion embedded in the insulative frame; wherein the protrusion has an end face at a lateral side thereof, and the reinforcing portion has an upper and lower edges buried in the protrusion and an exposed end face flush with the end face of the protrusion. 2.
