Part exposes operating mechanism 15 by the opening on loam cake 20 and the pedestal 10.
Memory card connector embodiment of the present invention, pedestal 10 is integrated, total is fit to plurality of specifications mmc card (MultiMediaCard, multimedia storage card), promptly can peg graft existing MS card, SD card, mmc card and MMC 4.0 cards, wherein, the MS card inserts in the jockey, and the metal terminal on the card is to contact with the 3rd group of connector 121; The SD card inserts in the jockey, and the metal terminal on the card is to contact with second group of connector 112; Mmc card inserts in the jockey, and the metal terminal on the card is to contact with second group of connector 112, but cooperate with whole nine terminals of SD card different is, the metal terminal on the mmc card only contacts with seven terminals in the middle of second group of connector 112; MMC 4.0 cards insert in the jockey, and seven metal terminals in the front row on the card are to contact with second group of connector 112 together with each terminal of row both sides, back, and four metal terminals are to contact with first group of connector 111 in the middle of the row of back.And, make that memory card connector integral installation distribution structure is simple because pedestal 10 is integrated, reliable.
The manufacturing process of memory card connector embodiment of the present invention, to shown in Figure 33, the step that comprises has as Fig. 7:
One, terminal drawing as shown in Figure 7, is provided with several location holes 51 at strip 30, in complexity terminal area 40 several location holes 52 is set, so that in the molding process, locate in mould;
Two, mould, shown in Fig. 8 and 9, terminal and the plastic parts 60 good punching press make up; And, as Figure 10, shown in 11 and 12, when the terminal punching press, for fear of distortion occurring, special being provided with between terminal and terminal strengthens the junction, and be provided with some holes 61 that cut in this enhancing junction, wherein, Figure 10 shows that the first area, Figure 11 shows that second area;
Three, strengthen cutting of junction, behind the plastic rubber shaping, terminal can redeformation, and strengthening the junction does not need, must cut, to avoid the short-circuit of terminals, 61 shapes are located in the hole that cuts before cutting, as Figure 13, shown in 14 and 15,61 shapes are located in the hole that cuts after cutting, as Figure 16, shown in 17 and 18;
Four, semi-finished product cut, and as shown in figure 19, half-finished upper body 11 of moulding are pulled down or are cut from strip;
Five, terminal and shell fragment riveted joint, as Figure 20,21, shown in 22 and 23, with the 3rd group of connector 121 of simple type terminal, and shell fragment 17 and 18, utilize the interface arrangment that on terminal or shell fragment 17 and 18, is provided with in advance, with the mode of riveted joint or extruding, utilize the deformable characteristics of interference stresses and plastic cement, terminal or shell fragment 17 and 18 are fixed in the set slot of the plastic cement lower body made in advance 12; As Figure 21, shown in 22 and 23, on shell fragment 17, be provided with card flanging 171, on shell fragment 18, be provided with card flanging 181;
Six, strip removes, and as shown in figure 24, the strip 31 at simple type terminal 121 places is pulled down or is cut, and obtains half-finished lower body 12;
Seven, ultrasonic wave binds, as Figure 25,26, shown in 27 and 28, purpose is that half-finished upper body 11 and lower body 12 bondings are integral, this will use the flange 123 that is located in the lower body 12, and groove 122 is interlocked with groove and flange in the corresponding upper body 11, certainly, before the two fastens to together, need the part of assembling, such as, the operating mechanism of band spring, should install in advance, then, use the ultrasonic wave Adhesive machine to make the groove and the flange that are provided with on plastic cement upper body 11 and the lower body 12 melt bonding mutually;
Eight, assembling as Figure 29, shown in 30,31,32 and 33, in the pilot hole 71 on the elbow one end insertion pedestal 10 of follower link 72, fastens to loam cake 20 on the pedestal 10 again, gets finished product to the end, finishes production process.
As seen, memory card connector manufacture method of the present invention, adopted mould, riveted and ultrasonic wave bind and finish the fixing of complicated terminal and be shaped, this manufacture method, connector is inner to be connected firmly, is not easy to break down.
Foregoing; it only is preferred embodiment of the present invention; be not to be used to limit embodiment of the present invention; those of ordinary skills are according to main design of the present invention and spirit; can carry out corresponding flexible or modification very easily, so protection scope of the present invention should be as the criterion with the desired protection range of claims.
