Description

RETRACTABLE ADAPTER FOR COMPUTER COMMUNICATIONS CARD

The present invention relates to electrical connectors and more particularly to communications cards for computers.

Communications cards such as PCMCIA cards having a flat low profile have recently become widely used with personal computers and portable computers, that configure the computer with selected peripherals to quickly and conveniently enable the computer to perform specific tasks. One particular task is to send and receive data by way of telephonic transmission, requiring a connector or modular jack at least having a plug- receiving cavity of standard configuration to be matable with transmission media connectors known as modular plugs in universal use, also having a standard configuration and include a manually deflectable latch to secure the plug to the jack in its mated relationship. Previously, external modem peripheral equipment has been used, or internal built-in modems, that have sufficient size to include full size modular jacks. Also, with PCMCIA cards, cable harnesses have been used with such a full sized modular jack on one end and a card- compatible connector on the other end.

Certain cards are known that include modular jacks connectable directly thereto and even affixed integrally thereto. Such cards are fully inserted into a low profile slot or socket of the computer housing, and must include an accessible portion for mating by a modular plug. For example, U.S. Patent No. 5,562,504 discloses that the jack subassembly, when not in use, is housed in one portion of the card within the general envelope of the card, and is removable from the card and connectable to a connector along the front end of the card in a manner to protrude from the card end and outwardly from the computer housing for connection with a mating plug. In U.S. Patent No. 5,183,404, the modular jack is retractable into the card and thus recessed into the computer housing when not in use. In commercially available card assemblies with retractable jack structure, the modular jack requires the mating plug and its cable to assume a distinct angled orientation with respect to the flat, low profile card for mating.

It is desired to provide a retractable adapter for a communications card that permits mating with a modular plug so that the transmission cable terminated by the plug is in an orientation substantially in-line with the general plane of the card, and assuredly captures the plug in the plug- receiving cavity.

The adapter of the present invention is assembled into a card to be releasable for use to an extended position to be exposed outside the computer housing, and retractable into the card assembly to be carried internally when not in use. The adapter includes an elongated body in-line with the general plane of the flat, low profile card and contains a plurality of contacts movable therewith during release and retraction, that are electrically connected at least during adapter use to circuits of a circuit element within the card assembly. A portion of the body remains recessed within the card when the adapter is released, while a forward portion extends from the leading edge of the card.

The adapter also includes a generally U-shaped frame having a cutout so as to surround the lateral edges of the forward body section, and is pivotably attached to the rear of the side edges of the forward body section to be rotated to an in-use position for connector mating when the adapter has been released from the card assembly. When the frame is rotated to its in-use position, the cutout of the frame, and the forward body section previously seated within the frame cutout, together define an aperture comprising a plug-

2 receiving cavity whose orientation is at only a shallow angle with respect to the card's profile.

In one aspect of the invention, the contacts of the adapter essentially become disengaged from the circuits of the circuit element when the adapter is retracted within the card assembly, and enter into electrical connection with the circuits when the adapter is released for use.

An embodiment of the adapter will now be described by way of example with reference to the accompanying drawings, in which:

Communications card assembly 10 includes adapter 40 of the present invention secured within the assembly at leading end 12 thereof when retracted as in FIG. 3, and releasable to extend from leading end 12 and outwardly from the computer housing, for mating with a complementary modular plug 14 (FIGS. 8 and 11) terminating a transmission cable 16. Release occurs through either a conventional push-push arrangement, or through actuation of a push button 18 as shown. Card 10 includes an insulative frame 20, a pair of conductive shield members 22, and a circuit element 24 (FIGS. 13 to 16) . Card assembly 10 has a low profile cross-section, and adapter 40 defines a low profile cross -section that fits within the low profile of the card.

Adapter 40 includes a body 42 having a forward section 44 and rearward section 46 (FIGS. 9 to 13), with forward section 44 projecting from card assembly 10 upon release, and with rearward section 46 remaining recessed within the adapter- receiving cavity of the assembly whether released or retracted. Mounted to forward body section 44 is U-shaped frame 48, surrounding forward body section 44 with inwardly facing surfaces being closely adjacent to forward wall 50 and opposed side edges 52 of forward section 44, prior to adapter release and pivoting of the frame as seen in FIGS. 2 and 5. Frame 48 and body 42 may be molded for example from thermoplastic resin such as liquid crystal polymer or polyester.

A pair of brackets 54 are affixed to both the frame and side edges 52 of forward body section 44. Adapter body 42, frame 48, brackets 54 and contacts 106 (FIGS. 6, 7 and 9 to 12) define a subassembly that is disposed and movable within an adapter housing 132 (FIGS. 13 to

16) which is secured within card frame 20. Rear ends 56 of brackets 54 are pivotably mounted to pivot embossments 58 at rear ends of side edges 52 by embossments 58 extending through elongate oblong or oval -shaped slots 60 near rear bracket ends 56 allowing relative translation of brackets 54 during pivoting of the frame. Pivot embossments 58 conclude in enlarged oblong or oval -shaped heads 62 angled from upper front to lower back as best seen in FIGS. 6 to 11. Forward ends 64 of brackets 54 are secured to bosses 66 near forward end 68 of frame 48, by open-ended slots 70 at forward bracket ends 64 receiving bosses 68 thereinto. Brackets 54 provide substantial support for the frame; preferably, brackets 54 are stamped from stainless steel .

Frame 48 includes a front beam 72 and a pair of opposed side arms 74 integrally joined thereto and extending rearwardly therefrom in recesses 76 along side edges 52 to rear ends 78. Rear arm ends 78 include pivot holes 80 in which are disposed frame pivot bosses 82 extending laterally from side edges 52 (see FIG. 9) . Frame 48 is securable to forward body section 44 as side arms 74 are deflectable during assembly to pass over frame pivot bosses 82 until they seat in pivot holes 80. Thereafter, brackets 54 are mountable to forward body section 44 by first being oriented parallel to oval- shaped heads 62 to receive heads 62 through complementary- shaped slots 60 whereafter brackets 54 are rotated downwardly to be snapped onto and retained on embossments 58 by heads 62. With frame 48 rotated downwardly from forward body section 44, brackets 54 are translated rearwardly until forward bracket ends 64 are just rearwardly of bosses 66, whereafter brackets 54 are urged forwardly so that bosses 66 are received into open-ended slots 70 temporarily deflecting the beams 84 of the forward bracket ends 64 apart, until bosses 66 are seated in enlarged detent 86 (FIG. 9) in a snap-fit. Bosses 66 also include enlarged heads 88 to retain forward bracket ends 66 thereon after assembly.

5 Optionally, beams 84 could be pried apart sufficiently to be snapped over enlarged heads 88.

In FIGS. 2 and 5 can be seen plug- receiving aperture 90 defined by adapter 40 upon pivoting of frame 48, aligned is at only a shallow angle with the plane of the card, such as about 15° as shown. Aperture 90 is defined generally by and between lower or aperture- adjacent surface 92 of forward body section 44, now- upwardly facing top surfaces 94 of ledges 96, and inwardly facing surfaces 98 of side arms 74. A rear stop surface 100 (FIG. 9) formed on an aperture-adjacent surface of body 42 will define the fully inserted plug position. Lower aperture portion 102 provides for passage of the forward end portion of latch arm 26 of plug 14 during plug mating and unmating, so that the rearwardly facing latch surface thereof will latch behind cooperating rearwardly facing latch surfaces 104 defined by front frame beam 72.

Adapter 40, when released and rotated open for plug receipt, is maintained against being pushed into the card during plug mating, by now-vertical rearwardly facing edges 106 of rear bracket ends 56 abutting leading edges of card shield covers 22. The fully rotated frame position is assured by abutment of lower frame arm surfaces 108 against stop surfaces 110 of the end face of recesses 76 (FIG. 9) , and also by forward ends of slots 60 of brackets 54 abutting against embossments 58 and rearward ends of slots 70 being abutted by bosses 66 of frame 48, since embossments 58 are offset from frame pivot bosses 82.

Movable contacts 112 are carried by adapter body 42, referring to FIGS. 6 and 7 (in which the adapter is shown inverted) and FIGS. 9 to 12. Elongate body sections 114 extend within respective passageways 116 (FIG. 12) from rearward end portions 118 containing retention barbs 120, forwardly to contact sections 122 and free end portions 124. Preferably, recesses 126 along sidewalls of the passageways receive barbs 120 thereinto in an interference fit, and recesses 126 serve to maintain elongate body sections 114 adjacent the bottom surfaces of the passageways, which are shown to have substantial height. Contact sections 122 forwardly of rear stop surface 100 are exposed in plug- receiving aperture 90, and when unmated (FIGS. 6 and 7) extend into the aperture. Free end portions 124 are hooked over and inwardly from lips 128 (FIG. 10) defined into forward body wall 50 and aligned with passageways 116, and are spring biased thereagainst upon assembly, assuring that contact sections 122 extend into aperture 90. Clearance slots 130 are formed opposed to lips 128 permitting free end portions 124 to be deflected thereinto upon plug mating, as contact sections 122 are engaged by contacts 28 of plug 14 and urged upwardly, as seen in FIG. 11. Maintenance of contact free end portions 124 in clearance slots 130 assures accurate spacing of contact sections 122. Referring now to FIGS. 13 to 16, insulative adapter housing 132 is seen, with body 42, frame 48, brackets 54 and contacts 112 defining a subassembly movable with respect to adapter housing 132. Movable contacts 112 are shown to cooperate with corresponding fixed contacts 134 of housing 132 having anchor portions 136 securely fixed within an insulative retaining body 138 of housing 132 rearwardly of adapter- receiving region 140. First or rear contact sections 142 of fixed contacts 134 are electrically connected to circuits of circuit element 24 of card 10. Elongate body portions 144 forward of retaining body 138 extend forwardly to angled spring arm or second contact sections 146 at forward ends thereof, and will be disposed along passageways 116 defined in body 40 opposed and spaced from elongate body sections 114 of contacts 112 therein when the subassembly is in its retracted position within housing 132. In FIGS. 13 and 14, the adapter subassembly is shown in its released position with respect to housing 132, and spring arm contact sections 146 of fixed contacts 134 are seen to have engaged raised sections 148 of contacts 112. Rearwardly extending tab 150 of rear body section 46 overlies a forward raised portion 152 of elongate body sections 144 of fixed contacts 134 and is abutted thereby to support spring arm contact sections 146 when deflected by raised sections 148 of contacts 112 to maintain spring bias thereagainst to establish an assured electrical engagement therewith, thereby connecting adapter contacts 112 to circuits of circuit element 24.

The adapter includes a compression spring 154 mounted to housing 124 around a post 156 to extend forward from retaining body 138 to abut push surface 158 at a forward end of spring receiving aperture 160 of adapter body 42, to bias the adapter subassembly forwardly when released by actuation of push button 18 of card 10. The forwardmost position of the subassembly is defined by forward stop surfaces 162 of body 42 abutting rearwardly facing stops 164 of housing 132. Travel of the subassembly is guided by T-shaped rails 166 of housing 132 in complementary undercut channels 168 of laterally extending flanges 170 body 42. If desired, the card frame can be modified to provide T- shaped rails for guiding the adapter subassembly, and to provide the retaining body for anchor portions 136 of fixed contacts 134 and the compression spring and post. Conventional push buttons 18 can be used, or the adapter can be of the push-push design.

The adapter of the present invention is retractable entirely into the communications card when not in use, and has a low profile of less than 5 mm to be disposed within cards having a desired profile of 5 mm. The adapter complies with the requirements for the modular jack cavity found in "FCC Rules for Registration of Telephone Equipment, Part 68, Subpart F, Connectors", pages F-1 to F-14, such as for mating with RJ45 plugs. Similar but smaller cavities can accommodate RJll plugs.
