Abstract
Abstract Connector box for shielded cables comprising upper and lower base parts and a printed board held between the upper and lower base parts. There is at least one jack and a terminal connector mounted on the printed board are conductively connected to each other by way of the printed board. The connector box is characterized in that the lower base part and upper base part form a housing and are die cast metal parts, and wherein the upper base part is seated by its peripheral edge on the lower base part in an electrically conductive manner. The housing encloses and shields at least the jack and a portion of the printed board. A structure is provided for holding the shielding of a cable on one of the base parts in electrically conductive contact therewith.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
144 words
A connector box for at least one shielded cable comprising: upper and lower base parts; a printed board held between said upper and lower base parts; at least one jack and a terminal connector mounted on said printed board and connected to each other conductively by way of said board, characterized in that said lower base part and said upper base part form a housing and are die cast metal parts, and wherein said upper base part is seated by its peripheral edge on said lower base part in an electrically conductive manner; said housing enclosing and shielding at least said jack and a predetermined portion of said printed board; at least one cable having shielding and an unshielded end; and means for holding said shielding of said at least one cable in electrically conductive contact with at least one of said base parts.
Claim 2
Dependent Claim
144 words
A connector box for at least one shielded cable comprising: upper and lower base parts; a printed board held between said upper and lower base parts; at least one jack and a terminal connector mounted on said printed board and connected to each other conductively by way of said board, characterized in that said lower base part and said upper base part form a housing and are die cast metal parts, and wherein said upper base part is seated by its peripheral edge on said lower base part in an electrically conductive manner; said housing enclosing and shielding at least said jack and a predetermined portion of said printed board; at least one cable having shielding and an unshielded end; and means for holding said shielding of said at least one cable in electrically conductive contact with at least one of said base parts.
Claim 3
Dependent Claim
49 words
The connector box according to claim 1, wherein said terminal connector is situated outside said upper base part on said printed board; and an electrically conductive cover in electrically conductive contact with at least one of said base parts, said electrically conductive cover covers and shields said terminal connector.
Claim 4
Dependent Claim
84 words
The connector box according to claim 2, further including additional shielding of metal on said lower base part which covers said unshielded end of said at least one cable held in place on said lower base part and which is in electrically conductive contact with said at least one of said base parts, said additional shielding either forms an integral part of, or is in contact with, said electrically conductive cover so that shielding is continuous from said cable shielding to said terminal connector.
Claim 5
Dependent Claim
25 words
The connector box according to claim 1, wherein said upper and lower base parts overlap at their contacting peripheries to define a stepped contact joint.
Claim 6
Dependent Claim
48 words
The connector box according to claim 1, wherein at least one said jack is surrounded by a receptacle of electrically conductive material soldered to the printed board, said jack having four side walls and a plug-in opening at one end for receiving a plug with a shielding plate.
Claim 7
Dependent Claim
99 words
The connector box according to claim 5, wherein said receptacle encloses said jack at least on said four side walls and on the one end of said jack having said plug-in opening, said receptacle having at least one springy tongue which engages in said plug-in opening of said jack; said at least one springy tongue contacting said shielding plate of said plug as it is plugged into said plug-in opening; and at least one tab on at least one side of said receptacle extending outwardly from said receptacle so that it makes springy contact with said upper base part.
Claim 8
Dependent Claim
106 words
The connector box according to claim 5, wherein said receptacle encloses said jack at least on said four side walls and on the one end of said jack having said plug-in opening, said receptacle having at least one springy tongue which engages in said plug-in opening of said jack; said at least one springy tongue contacting said shielding plate of said plug when said plug is plugged into said plug-in opening; and at least one tab on at least one side of said receptacle extending outwardly from said receptacle so that it makes springy contact with a springy plug tongue of said plug to be connected.
Claim 9
Dependent Claim
30 words
The connector box according to claim 1, wherein said lower base part and said upper base part are connected to each other and held together under tension by self-tapping screws.
Claim 10
Dependent Claim
82 words
The connector box according to claim 1, wherein said printed board further includes a conductive lamination on at least one side thereof, and said printed board is clamped between said lower base part and said upper base part in such a way that said conductive lamination is held under pressure in conductive contact with at least one of said base parts, and said at least one of said base parts having spikes which penetrate into said conductive lamination of said printed board.
Claim 11
Dependent Claim
55 words
The connector box according to claim 1, further including a contact strap made of springy metal attached by means of an electrically conductive screw to said lower base part; said contact strap extending over the shielding of said at least one cable proximate said unshielded end and pressing said shielding against said lower base part.
Claim 12
Dependent Claim
54 words
The connector box according to claim 1, wherein said at least one cable has external insulation, the connector box further including a strain-relief strap on said lower base part which extends over said at least one cable at the external insulation and holds said at least one cable firmly against said lower base part.
Claim 13
Dependent Claim
31 words
The connector box according to claim 11, further including a set screw for an accessory ground wire of said shielding of said at least one cable on said lower base part.
Claim 14
Dependent Claim
74 words
The connector box according to claim 1, further including a non-conductive cover proximate the peripheral edge of said upper base part, wherein said at least one cable is held in place on the bottom of said lower base part, said at least one cable having core leads which are guided around said lower base part whereby said non-conductive cover prevents a contact of said core leads with the edge of said lower base part.
Claim 15
Dependent Claim
52 words
The connector box according to claim 1, further including additional shielding of metal on said lower base part which covers said unshielded end of said at least one cable held in place on said lower base part and which is in electrically conductive contact with at least one of said base parts.
Claim 16
Dependent Claim
109 words
The connector box according to claim 1, further including a shielding contact part made of metal in electrically conductive contact on said lower base part; wherein said at least one cable has external insulation and an accessory ground wire extending beyond said external insulation; and whereby the accessory ground wire held in place on said lower base part can be inserted into said shielding contact part and clamped in place there, said shielding contact part being a part stamped out of sheet metal which can be affixed to said lower base part and which has two legs, whereby the accessory ground wire can be clamped between said two legs.
