A connector assembly () for providing electricity to an electroluminescent display () that is mounted on an outer face of a carrier plate (), includes a first connector () that has an insulative body () with a rearwardly-opening slit () that receives an edge of the carrier plate, the body having inner and outer body arms () on opposite sides of the slot. The first connector also has a plurality of U-shaped contact elements () with parallel inner and outer ends () that lie in the different body arms. The outer end of each contact element engages a conductive pad () on the carrier plate but the rest of the outer end is surrounded by the outer body to safeguard against a person touching the contact element outer end. The inner end of each contact element is held spaced from the inner face of the carrier plate by the body inner arm that surrounds the inner end.

A contact assembly () for providing electricity to an electroluminescent display () that is mounted on an outer face of a carrier plate (). The contact assembly includes contact pads () on the outer face of the carrier plate and a first connector () that has an insulative body () and a pair of contact elements () with outer ends () that each engages one of the conductive pads (). The outer end of each contact element and the contact pads, are surrounded by an outer body portion to safeguard against a person touching the contact element outer end.

Contact assembly

A pair of mated connector ( ) are latched together by a pair of studs ( ) on a first connector that are inserted into a pair of sleeve assemblies ( ) on the second connector, with each stud having a stud groove ( ) that receives an inwardly projecting flange ( ) of the sleeve assembly. The sleeve assembly includes an outer sleeve ( ) with an internal sleeve groove ( ), and a spring clip ( ) lying in the sleeve groove. The spring clip is largely in the form of a cylinder with an axially-extending slot ( ) that allows the cylinder to resiliently expand and contract. The spring clip is trapped in the sleeve groove and has an inwardly-projecting flange ( ) that snaps into the stud groove when the stud is fully inserted.

A connector is mounted on a circuit board by a pair of elongated fasteners ( ) that each have a connector end ( ) that is fixed to the connector housing and a board mount end ( ) that is fixed in mount holes ( ) in the circuit board. The board mount ends of the fasteners are press fit into circuit board holes as the termination ends ( ) of the connector contacts are inserted into plated holes in the board. Each fastener is attached to the connector by passing the connector end of the fastener through a hole ( ) in a plate-like metal wing ( ) of the connector and then press fitting the connector end of the fastener to the wing. The fastener has an elongated pin-like middle portion ( ) that can be bent 90&deg; so most of the connector can lie beyond an edge ( ) of the circuit board and partly in the plane of the circuit board.

Board mounted connector

In a connection assembly (,) of printed-circuit board and connector, a printed-circuit board (,) and a connector (,) can be fixed positionally accurately in relation to one another by means of position holders (,) provided on the connector (,). The position holders are constituted of soldering pins (,) and the printed-circuit board (,) is provided with soldering pads (,) which can be connected to the opposing soldering pins (,) by soldering. There is provided in this manner a connection assembly (,) of printed-circuit board and connector in which the positionally accurate fixing of a printed-circuit board (,) and a connector (,) is more easily produced and more precisely assembled than has been possible to date.

A molded plastic saddle (19) lies at the front of a PC card (10), the saddle connecting to the front connector (18), the front of the circuit board (16), and the front of the lower cover part (12) in connections that are easily performed by the PC card maker who assembles the components. The saddle has laterally spaced opposite saddle side portions (120, 122) connected by a laterally-extending crossbar (28). Each saddle side portion has a cutout (38) in its side, and the sheet metal lower cover part has upstanding side rails (51, 52) with front portions forming holdown tabs (53) that are bent to extend into the cutouts to lock the front of the lower housing part to the saddle and thereby to the front connector and the front end of the circuit board.

A PC card (30) of standard PCMCIA outside dimensions can connect a Micro Sim card C to a host connector 16 that lies at the rear end of a host passageway 12. The PC card has a housing 10 that includes shell halves (32, 34) with horizontal upper and lower parallel plane main walls (44, 46) which, between them, form a cavity (48) holding a circuit board (36). A small card connector (64) for receiving the Micro Sim card lies on the upper face (37) of the circuit board (36). The upper PC card shell half (32) has a slot (80) for insertion or extraction of the Micro Sim card (C) from the small card connector.

A PC card is provided with internal electromagnetic shielding to isolate two or more different circuit component areas of the card, which facilitates mounting of the shielding. In one card which is an extended card having a standard forward portion (102) containing electronic components, and having an extended rearward portion containing an antenna (100) for radiating electromagnetic energy, the shielding includes a strip-shaped portion (22) of electrically conductive material that extends across the width of the circuit board and that has opposite ends that terminate near the intersection between the two card parts, with the shielding having pins (31) that project into holes (150) in the circuit board. In another PC card a plate-like filler (38, 39)which lies between the circuit board (151) and a sheet metal cover part, has a plurality of holes (41-47), and strip-like shielding (21') extends around the periphery of the hole and is mounted thereat to the filler, with the shielding extending above and below the filler and contacting the sheet metal cover part and the circuit board.

PC card with internal EMI shielding

A frameless IC card is provided, with front and rear support structures that each includes an electrical connector, with a sheet metal cover mounted on the front and rear board supports without requiring a separate plastic frame to tie the components together. The rear support structure includes at least one rear connector (11', 12', FIG. 3) fixed to the circuit board rear end (104') and an end cap (16') at the rear of the IC card. The end cap has upper and lower flanges (126T, 126B) that form a recess therebetween that closely receives the rear of the rear connector housing to fix their relative vertical positions. The rear end cap has forwardly-extending legs (47, 48) at opposite sides, with each leg having a lug (51, 52) forming a rearwardly-facing shoulder (150) that fits into a cutout (53) at a side of the circuit board, to prevent forward movement of the connector and circuit board out of the rear end cap. Different types of IC cards have their circuit boards at different heights, which is accomplished by mounting the rear connector at different heights on the circuit board.
