Definitions
- This invention relates to a folded sheet metal shielding shell for receiving an electrical connector for surface mounting on a circuit board, and to an assembly comprising the connector and the shield with a mounting flange.
- U.S. patent number 5,017,156 a metal shield for an electrical connector, constructed from a metal plate that has been folded to form an enclosure having an open seam defined by inwardly projecting end portions of the shield.
- the seam faces a printed circuit board, when the shield has been assembled to an electrical connector and surface mounted on the board.
- the seam lies opposite to projecting mating portions of the terminals of the connector.
- the connector is retained in the shield by means of pawls projecting from said end portions alongside the seam and which engage in an opening in a dielectric housing of the connector. Since the seam faces the circuit board, electro-magnetic induction radiating from said mating portions can leak through the seam directly to the circuit board to interfere with the circuitry thereon. The seam will in any event open out as a result of thermal changes and distortion of the shield when the connector is mated with a mating connector.
- a folded sheet metal shielding shell which is open at both ends is secured about an electrical connector for surface mounting on a circuit board, by means of inward protrusions on opposite side walls of the shell, which protrusions engage between pawls on a terminal support of the connector and proximate walls of the terminal support.
- a bottom wall of the shielding shell has a mounting post bent downwardly therefrom.
- U.S. Patent number 4,842,555 a folded sheet metal shielding shell for receiving an electrical connector for surface mounting on a circuit board.
- the connector is secured in the shell by means of inturned flanges depending from a top wall of the shielding shell and detents in side walls of the shell, which anchor the shell to the body of the connector.
- Mounting posts project from bottom edges of the side walls of the shielding shell.
- the present invention is intended to provide a shielding shell for a surface mount electrical connector, into which shell the connector can readily be inserted without distortion of the shell side walls, so as to be secured in the shell with a snap action, minimal adaption of the housing of the connector being needed to achieve this end.
- the present invention is further intended to provide a folded metal shielding shell for a surface mounted electrical connector and a mounting flange for use in mounting the connector and its shield to a panel and for embracing the shield so as to maintain the shield closed under all conditions.
- a folded sheet metal shielding shell for receiving an electrical connector for surface mounting on a circuit board comprises a top wall, and a bottom wall which is to be located proximate to the circuit board when the connector is mounted thereon.
- First and second side walls are connected to the top and bottom walls and define in co-operation therewith, a tubular enclosure for receiving the connector.
- a mounting post depends from the shell for connection to a grounding conductor on the circuit board.
- the second side wall has two parts which co-operate to define a seam extending longitudinally of the shielding shell, the bottom wall being seamless.
- any electro-magnetic field radiated by the terminals of the connector can only escape from the shield laterally, and not therefore in the direction of the circuit board.
- a mounting flange for use in mounting the connector and its shield to a panel may be arranged to embrace the shield as to maintain the seam closed under all conditions.
- the mounting flange may embrace multiple shields of corresponding multiple connectors.
- multiple fasteners have been required to mount multiple shields to a panel.
- the mounting flange itself may be mounted to a panel so as to reduce the number of fasteners heretofore required.

- a flange depending from the top wall of the shielding shell and overlapping the seam may be provided, the flange having a tongue projecting beneath, and engaging, the bottom wall of the shielding shell as to provide some restraint against the seam opening out should lateral leakage of said induction be required to be reduced.
- the first side wall projects rearwardly beyond the second side wall and a cantilever flange connected to the top wall provides a rearward extension of the second side wall.
- the cantilever flange has formed therein a latching member in the connector and is resiliently deflectable away from the first side wall.
- a mounting post depends from the cantilever flange below the bottom wall of the shell for connection to a grounding conductor on the circuit board.
- the deflectability of the cantilever flange ensures that when the connector is inserted into the shielding shell by way of its open rear end, the latching member of the connector can engage in the latching opening of the cantilever flange with a snap action without distortion of the side walls of the shielding shell and that the connector can readily be inserted into the shell.
- a tongue may extend from the cantilever flange under the bottom wall of the shell to assist in guiding the cantilever flange during its deflection and subsequent resiling movement.
- the mounting post may depend from a cross piece which is connected to the tongue and the flange, the cross piece having been bent up to lie in a complementary cut out in the cantilever flange.

- the seam 20 of the shell 4 will tend to open, although it is to some extent restrained from doing so by the engagement of the flange 46 and its tongue 50 with the side wall 14 of the shell 4. Since the seam 20 is defined by a side wall of the shell 4, electro-magnetic induction radiating from the connector 6 is not directed towards the board PCB so as to interfere with the electronic circuitry thereon.

Abstract
Description
- This invention relates to a folded sheet metal shielding shell for receiving an electrical connector for surface mounting on a circuit board, and to an assembly comprising the connector and the shield with a mounting flange.
- There is disclosed for U.S. patent number 5,017,156, a metal shield for an electrical connector, constructed from a metal plate that has been folded to form an enclosure having an open seam defined by inwardly projecting end portions of the shield. The seam faces a printed circuit board, when the shield has been assembled to an electrical connector and surface mounted on the board. The seam lies opposite to projecting mating portions of the terminals of the connector. The connector is retained in the shield by means of pawls projecting from said end portions alongside the seam and which engage in an opening in a dielectric housing of the connector. Since the seam faces the circuit board, electro-magnetic induction radiating from said mating portions can leak through the seam directly to the circuit board to interfere with the circuitry thereon. The seam will in any event open out as a result of thermal changes and distortion of the shield when the connector is mated with a mating connector.
- According to U.S. Patent No. 4,637,669 a folded sheet metal shielding shell, which is open at both ends is secured about an electrical connector for surface mounting on a circuit board, by means of inward protrusions on opposite side walls of the shell, which protrusions engage between pawls on a terminal support of the connector and proximate walls of the terminal support. A bottom wall of the shielding shell has a mounting post bent downwardly therefrom.
- There is disclosed in U.S. Patent number 4,842,555, a folded sheet metal shielding shell for receiving an electrical connector for surface mounting on a circuit board. The connector is secured in the shell by means of inturned flanges depending from a top wall of the shielding shell and detents in side walls of the shell, which anchor the shell to the body of the connector. Mounting posts project from bottom edges of the side walls of the shielding shell.
- The present invention is intended to provide a shielding shell for a surface mount electrical connector, into which shell the connector can readily be inserted without distortion of the shell side walls, so as to be secured in the shell with a snap action, minimal adaption of the housing of the connector being needed to achieve this end.
- The present invention is further intended to provide a folded metal shielding shell for a surface mounted electrical connector and a mounting flange for use in mounting the connector and its shield to a panel and for embracing the shield so as to maintain the shield closed under all conditions.
- A folded sheet metal shielding shell for receiving an electrical connector for surface mounting on a circuit board, comprises a top wall, and a bottom wall which is to be located proximate to the circuit board when the connector is mounted thereon. First and second side walls are connected to the top and bottom walls and define in co-operation therewith, a tubular enclosure for receiving the connector. A mounting post depends from the shell for connection to a grounding conductor on the circuit board. The second side wall has two parts which co-operate to define a seam extending longitudinally of the shielding shell, the bottom wall being seamless.
- Thus should the seam be opened to some extent as a result of thermal changes or the mating of the connector with a mating connector, any electro-magnetic field radiated by the terminals of the connector can only escape from the shield laterally, and not therefore in the direction of the circuit board.
- A mounting flange for use in mounting the connector and its shield to a panel, may be arranged to embrace the shield as to maintain the seam closed under all conditions.
- The mounting flange may embrace multiple shields of corresponding multiple connectors. Heretofore, multiple fasteners have been required to mount multiple shields to a panel. The mounting flange itself may be mounted to a panel so as to reduce the number of fasteners heretofore required. The mounting flange further embraces the multiple shields, not only to maintain the shields closed, but to mount the multiple connectors side by side in a compact grouping that eliminates space between the shields that was heretofore required for the fasteners.
- Where the assembly comprising the shield and the connector is not to be panel mounted, a flange depending from the top wall of the shielding shell and overlapping the seam, may be provided, the flange having a tongue projecting beneath, and engaging, the bottom wall of the shielding shell as to provide some restraint against the seam opening out should lateral leakage of said induction be required to be reduced.
- The first side wall projects rearwardly beyond the second side wall and a cantilever flange connected to the top wall provides a rearward extension of the second side wall. The cantilever flange has formed therein a latching member in the connector and is resiliently deflectable away from the first side wall.
- A mounting post depends from the cantilever flange below the bottom wall of the shell for connection to a grounding conductor on the circuit board.
- The deflectability of the cantilever flange ensures that when the connector is inserted into the shielding shell by way of its open rear end, the latching member of the connector can engage in the latching opening of the cantilever flange with a snap action without distortion of the side walls of the shielding shell and that the connector can readily be inserted into the shell.
- A tongue may extend from the cantilever flange under the bottom wall of the shell to assist in guiding the cantilever flange during its deflection and subsequent resiling movement. Conveniently the mounting post may depend from a cross piece which is connected to the tongue and the flange, the cross piece having been bent up to lie in a complementary cut out in the cantilever flange.
- Where the second side wall defines the seam of the folded shielding shell, which seam could open, for example, as a result of thermal changes, so as to allow the escape of electro-magnetic induction from the shell, when the connector is in use, the cantilever flange preferably overlaps the second side wall and thus the seam and cooperates with the tongue to restrain opening of the seam.

shell 4 which was stamped, formed and folded up from a single piece of sheet metal stock provides a four sided, generally rectangular cross section tubular enclosure for theconnector 6. Theshell 4 comprises seamless planar top and bottom walls, 8 and 10, respectively, a planar seamlessfirst side wall 12, and asecond side wall 14. Theside wall 14 comprises substantially identical upper andlower parts longitudinal seam 20, which was formed when theshell 4 was folded up. Theside wall 14 is bowed outwardly of theshell 4. Theshell 4 has an openforward end 22 and an openrear end 24. Theside wall 12 extends over the full length of theshell 4 and has arear edge 26 which projects rearwardly beyond thetop wall 8 and is inclined downwardly and rearwardly therefrom. Theside wall 12, at its bottom rear end, below theedge 26, aconnector anchoring tab 28 which, before assembly of theshell 4 to theconnector 6 projects rearwardly of theshell 4 in coplanar relationship with theside wall 12. Theside wall 12 has formed therein, a substantially square latching opening 30 proximate to therear edge 26. Amounting post 32 havinglateral barbs 34 depends from across piece 33 received in a cut out 35 in theside wall 12, thecrosspiece 33 being connected at each end to the bottom edge of theside wall 12. Themounting post 32 is located between thetab 28 and the opening 30. Thebottom wall 10 of theshell 4 is formed with a rectangular, elongate, three sided cut out 36 positioned forwardly of therear edge 33 of thetop wall 8. The cut out 36 is open at its end remote from theside wall 12, proximate to therear edge 40 of theside wall part 18. The cut out 36 has aforward edge 42. Thetop wall 8 has arear portion 44 which projects laterally beyond theside wall 14 and from which depends at right angles to thetop wall 8, a bent downplanar flange 46 having aforward margin 47 overlapping a rearwardly extendingmargin 48 of theside wall 14 and thereby overlapping the rear end portion of theseam 20. There extends inwardly of theshell 4, from the bottom end of theflange 46, and normally thereof, atongue 50 which projects beneath, and engages, thelower part 18 of theside wall 14. Rearwardly of itsmargin 47, theflange 46 is formed with a substantially square latching opening 52 which is aligned with the opening 30 in theside wall 12. Amounting post 54, which is identical with themounting post 32 depends from across-piece 55 received in a cut out 57 in theflange 46. Thecross-piece 55 is connected at one end to thetongue 50 and its opposite end to the bottom edge of theflange 46. Theflange 46 has arear edge 56 sloping downwardly and rearwardly from thetop wall portion 44 in alignment with theedge 26 of theside wall 12. There projects rearwardly from theflange 46, below itsrear edge 56, aconnector anchoring tab 58 which is opposite to thetab 28 of theside wall 12. As shown in Figure 1 thetab 58 projects rearwardly from theside wall 46 in coplanar relationship therewith before theshell 4 is assembled to theconnector 6. At their forward ends, thewalls shell 4 have outwardly turnedguide flanges shell 4. Theseam 20 bisects theflange 66. Outwardly convex dimples are formed in thewalls connector 6 comprises a one-piece, molded,dielectric housing 70, having abody 72 in the form of a substantially rectangular flat block. Terminal protecting lugs 74 project rearwardly from opposite lateral edges of thebody 72. Eachlug 74 has a downwardly inclinedrear face 76 the length and inclination of which are identical with those of therear edge 26 of theside wall 12 and therear edge 56 of theflange 46. From the bottom end of eachrear face 76 of eachlug 74, depends a vertical, rear,tab abutment surface 78. Eachlug 74 has a flat bottom surface from the rear part of which depends a rear stand-off stub 82. Each of two flat, opposite outer faces 84 of thehousing 70 is formed with alatch member 86 having arear abutment shoulder 88 extending normally of theface 84 and a forward camming face 90 sloping forwardly from theshoulder 88 towards theface 84. Thebody 72 has a flattop face 92 and aflat bottom face 94 which is stepped slightly above the bottom faces 80 of thelugs 74. There depends from each end of thebottom face 94, a forward stand-off stub 96. Thebody 72 has forwardface 98 and arear face 100. There projects rearwardly form the lower part of theface 100, a terminaltail spacer comb 102 defining a single row of contacttail receiving notches 104. Upper and lower rows of terminal receiving, throughcavities faces forward face 98, aterminal support plate 108, the upper surface of which is formed with an upper row ofterminal receiving grooves 110 and the lower surface of which is formed with a row of lowerterminal receiving grooves 112. Eachgroove 110 communicates with arespective cavity 106 and eachgroove 112 communicates with arespective cavity 107. Also, each of thegrooves respective channel 114 opening into the forward end of thesupport plate 108. - The
connector 6 further comprises a plurality of upper and lowerelectrical terminals rectilinear mating portion 120 having a latchinglip 122 at its forward end, anintermediate portion 124 formed with latchingtongues horizontal part 131 and avertical part 133 depending from thepart 131 and terminating in asolder foot 132. As will be best be apparent from Figure 7, themating portion 120 of eachupper terminal 116, lies in arespective groove 110, with theintermediate portion 124 of the terminal in arespective cavity 106. Themating portion 120 of eachlower terminal 118 lies in arespective groove 112 and theintermediate portion 124 of the terminal being received in arespective cavity 107. Each terminal 116 and 118 is held in position by the engagement of itslatching lip 112 in arespective channel 114, the engagement of itslatching tongue 126 against theforward face 98 of thebody 72, and by the engagement of itslatching tongue 128 against a shoulder located just forwardly of therear face 100 of thebody 72. Thecontact tails 130 of the terminals lie between theprotective lugs 74 of thehousing 70 with theparts 133 of the contact tails received in respective ones of the notches of the 104 of thecomb 102 and with thesolder feet 132 of the terminals below the bottom faces 80 of thelugs 74. - The
connector 6 is assembled to the shieldingshell 4, by inserting theconnector 6, with itsterminal support 108 leading, into theshell 4 through its openrear end 24, until eachlatch member 86 of thehousing 70 is latchingly received in a respective latching opening 30 or 32 of theshell 4. During the insertion of theconnector 6 into theshell 4, the camming faces 90 of thelatch members 86 cam theflange 46 away from the tapered rear part of theside wall 12 of theshield 4, until the abutment shoulders 88 of thelatch members 86 pass respective rear edges of theopenings 52, whereby theflange 46 and the tapered rear part of theside wall 12 snap back into their initial positions so that theconnector 6 is restrained from withdrawal from theshell 4. Forward movement of theconnector 6 into theshell 4 is limited by the abutment of thespacer comb 102 against the rear edge of thetongue 50 and the rearmost edge of thebottom wall 10, as will best appear from Figure 2. In the fully inserted position of theconnector 6, thetop face 92 and thebottom face 94 of thehousing body 72 fit snugly against the inner surfaces of the top andbottom walls shell 4. Theconnector 6 is further secured in theshell 4, by bending in thetabs - The
finished assembly 2, thus provided, is surface mounted to the board PCB as shown diagrammatically in Figure 7, with the mountingpost barbs 32 of the mounting posts securing them from withdrawal from the holes. Thestubs solder feet 132 of the terminals against printed conductors on the board PCB. With theassembly 2 so mounted on the board PCB, thesolder feet 132 are soldered to the printed conductors, these being connected to electronic circuitry on the board PCB and theposts - When the
connector 6 is mated with a mating shielded electrical connector on a further printed circuit board, and/or by reason of temperature changes, theseam 20 of theshell 4 will tend to open, although it is to some extent restrained from doing so by the engagement of theflange 46 and itstongue 50 with theside wall 14 of theshell 4. Since theseam 20 is defined by a side wall of theshell 4, electro-magnetic induction radiating from theconnector 6 is not directed towards the board PCB so as to interfere with the electronic circuitry thereon. - The second embodiment of the invention will now be described with references to Figures 8 and 9 in which those parts which have already been described above with reference to Figures 1 to 7, bear the same reference numerals and parts which are similar thereto bear the same reference numerals but with the addition of a prime symbol.
- The
connector assembly 200 shown in Figures 8 and 9 differs from theconnector assembly 2 in that it is for mounting to a metal panel P. To this end, the top wall 8' and the bottom wall 10' of the shell 4' are each formed with a pair of forwardly projectingtabs 204, the walls 8' and 10' also each being formed with pair of struck-out, resilient stops 202. Thetabs 204 are bisected by the longitudinal axis X-X of the shell 4'. Thestops 202 of each pair are equally spaced from that axis, each stop 202 of the top wall 8' being disposed opposite to arespective stop 202 of the bottom wall 10'. Eachstop 202 has a forwardly bowedabutment surface 206 projecting away from the shell 4'. Eachtab 204 is rectilinear and is coplanar, as shown in Figure 8, with its respective wall of the shell 4' from which thetab 204 projects. The connector in this embodiment is identical with theconnector 6 described above and is similarly assembled to its shielding shell. - The
assembly 202 is provided with a stamped outmetal flange 208 for attachment thereto, for mounting theassembly 2 to the panel P. Theflange 208, which is in the form of a substantially rectangular flat plate, has a central cut-out 210 dimensioned snugly to receive the shell 4'. Theflange 208 has a tapped, throughhole 212 on each side of the cut out 210. Theflange 208 also has a pair ofopposed recesses 214 formed in its upper and lower margins, each opening into the cut-out 212 and into a respective edge of theflange 208. - The
flange 208 is assembled to the shell 4' by inserting the latter, with thetabs 204 leading, through the cut-out 210 until the abutment surfaces 206 of thestops 202 engage the rear face of theflange 208. Thetab 204 of the top wall 8' is then bent up into theupper recess 214, thetab 204 on the bottom wall 10' being bent down into thelower recess 214, as shown in Figure 9. Theflange 208 is thereby securely fastened to the shell 4' with thestops 202 resiliently engaging against the rear face of theflange 208. Since the shell 4' is snugly contained in the cut out 210, theseam 20 is maintained firmly closed. Theconnector 6 may be assembled to the shell 4' either before or after the latter has been assembled to theflange 208. - The panel P, which is shown only in fragmentary form, has a cut out 216 having opposed
lateral extensions 218 for receivingrespective bolts 220. In order to mount theconnector assembly 200 to the panel P, theflange 208 on theassembly 200 is engaged against the rear face of the panel P with each of the tappedholes 212 of theflange 208 aligned with arespective extension 218 of the cut out 216 of the panel P. Thebolts 220 are then screwed home into respective ones of theholes 212 until the heads of thebolts 220 tightly engaged the front face of the panel P. By virtue of theflange 208, theseam 20 cannot open at all by reason of temperature changes, and/or when the connector is mated with a mating connector. Only the twobolts 220 are required to mount multiple connectors, whereas, heretofore each connector requires its own fasteners to mount to the panel P and to a common mounting flange 208', Figure 10. - As shown in Figure 10 a plurality of
connector assemblies 200 may be mounted in juxtaposed relationship to a common panel P' having a pair of juxtaposed cut outs 216' each having a lateral extension 218', these extensions being oppositely directed. In order to enable theassemblies 200 to be mounted to the panel P', they are secured to a common flange 208' having a pair ofjuxtaposed cut outs 210. Eachassembly 200 is secured in a respective cut out 210 in the flange 208' in the manner described above with reference to Figure 9. The flange 208' is engaged against the rear fact of the panel P' with each hole 212' in alignment with theextension 218 of a respective cut out 216' of the panel P' andbolts 220 are inserted through the extensions 218' and are screwed home into the tapped holes 212'. - The
tabs 204, as well as serving to secure the shell 4' to theflange 208 or 208' also provide an electrical path through the shell and the flange to the metal panel. Thetabs 204 that secure the shells 4' to the common flange 208' overlap sides of the respective cut outs except on sides of the cut outs that are between the electrical connectors to allow the electrical connectors in close proximity to one are then on the mounting flange.
