Abstract
A cable plug is described for connecting a cable to the rear of an IC (integrated circuit) card of the PCMCIA type, which makes a simple ground connection between the cable shield and the card cover. Case shells (31, 32, FIG. 2 ) of the plug connector have rear ends with a crimp (37) and a bridge (40) that directly engage a cable shield (24). The case shells have front ends that form forwardly-projecting tabs (43, 44). The tabs project through slits (45, 46) of a carrier plate portion (12) and directly engage sheet metal cover portions of the IC card. The tabs lie slightly above and below plug parts (13, 14) of the carrier, so the front parts protect the tabs.
Claims9
A shielded cable plug for attachment to a cable that has a cable shield, and for mating with the rear end of an IC card that has a laterally-extending width and that has a vertically-extending height which is less than half of said width, and that has a rear end with a central latch-receiving opening (78) and that has a pair of contact-receiving openings (55, 56) lying on laterally opposite sides of said latch-receiving opening, and wherein said IC card has a sheet metal top cover portion (130), comprising:
- a dielectric cable plug carrier (11) which has a laterally-extending plate portion (12), a latch portion that projects forward of said plate portion and that can project into said latch-receiving opening (78) of said card, and a pair of contact-holding plug parts (13, 14) that project forward of said plate portion and can be inserted into said contact-receiving openings of said card;
- a sheet metal shield case (30) which lies primarily rearward of said plate portion and that has a case rear portion that is electrically connectable to said cable shield;
- said plate portion having a first slit (45), and said sheet metal case has a first tab (43) projecting forwardly through and forwardly beyond said slit to engage said card top cover portion.
A combination of a shielded cable plug for attachment to a cable that has a cable shield, and an IC card, where said cable plug and said card each has a laterally-extending width and has a vertically-extending height which is less than half of the width, wherein said card has a top sheet metal cover portion and has a rear end with a rear dielectric connector housing lying under said sheet metal top cover portion, said dielectric connector housing having a pair of laterally-spaced plug-receiving openings and said plug has a dielectric carrier with a laterally-extending plate portion and with a pair of contact-holding plug parts that project forwardly from said plate portion into said plug-receiving opening of said card, wherein:
- said cable plug has a sheet metal shield case with a rear case portion that is electrically connectable to said cable shield, said sheet metal shield case lying primarily rearward of said carrier plate portion but having a forwardly projecting tab that projects forward of said carrier plate portion and that engages said top sheet metal cover portion.
A shielded cable plug for attachment to a cable that has a cable shield, and for mating with the rear end of an IC card, comprising:
- a contact-holding dielectric cable plug carrier which has a laterally-extending carrier plate portion;
- a sheet metal shield case which lies primarily rearward of said plate portion, said shield case having upper and lower case shells, with said lower case shell having a rear portion;
- said rear portion of said lower case shell forming a pair of upstanding fingers that are integral with the rest of said lower case shell, said fingers being horizontally spaced to closely receive said cable shield between them;
- said upper case half having a rear portion with a rearwardly-extending projection forming a bridge that lies largely above and between said fingers, with said fingers being tall enough to crimp around said bridge when crimping around said cable shield.
