Claim 3

A cable assembly comprising: an insulating housing comprising a plurality of channels and a cavity extending along a direction perpendicular to the channels; a plurality of circuit modules each comprising a circuit board being retained in a corresponding channel of the housing and defining therethrough an aperture aligned with the cavity of the housing, a plurality of cables having front portions electrically connecting to a rear edge portion of the circuit board, and a casing disposed outside the circuit board and the cables, the casing defining a hole therethrough; a cover comprising first and second halves jointed together and being attached to the housing; and first and second fastening means respectively inserted into the holes of the casings and the apertures of the circuit boards through the cavity of the housing; wherein the casing comprises opposite first and second faces and a plurality of protrusions protruding from the first and second faces, respectively; wherein the protrusions on the opposite first and second faces slope along opposite directions; wherein the casing comprises a plurality of recesses respectively defined on the first and second faces thereof, each recess correspondingly receiving a protrusion of an adjacent circuit module; wherein each circuit board defines at least one hole therethrough, the at least one hole being filled with material during overmolding the casing.

Claim 4

A cable assembly comprising: an insulating housing comprising a plurality of channels and a cavity extending along a direction perpendicular to the channels; a plurality of circuit modules each comprising a circuit board being retained in a corresponding channel of the housing and defining therethrough an aperture aligned with the cavity of the housing, a plurality of cables having front portions electrically connecting to a rear edge portion of the circuit board, and a casing disposed outside the circuit board and the cables, the casing defining a hole therethrough; a cover comprising first and second halves jointed together and being attached to the housing; and first and second fastening means respectively inserted into the holes of the casings and the apertures of the circuit boards through the cavity of the housing; wherein the casing comprises opposite first and second faces and a plurality of protrusions protruding from the first and second faces, respectively; wherein the protrusions on the opposite first and second faces slope along opposite directions; wherein the casing comprises a plurality of recesses respectively defined on the first and second faces thereof, each recess correspondingly receiving a protrusion of an adjacent circuit module; wherein each circuit board defines at least one hole therethrough, the at least one hole being filled with material during overmolding the casing.

Claim 5

A cable assembly comprising: an insulating housing; a plurality of circuit boards juxtaposed in the insulating housing, each circuit board extending along a lengthwise direction while the circuit board side by side arranged with one another along a lateral direction, each circuit board having a rear edge portion; a plurality of sets of cables being arranged in a matrix manner on a lateral plane, each set being commonly mounted on the rear edge portion of each of the circuit boards; and a plurality of casings being respectively overmolded onto the individual circuit boards and encasing therein the rear edge portion of the circuit board and corresponding cables; further comprising a fastening means, and wherein each casing defines a through-hole for insertion of the fastening means; wherein each of said casings defines openings and protrusions on two opposite surfaces so as to allow said casings side by side stacked to each other under a condition that the protrusions of one casing are received in the corresponding openings of the adjacent casing; wherein in each of the casings portions of the cables around the corresponding protrusions are deflected toward the corresponding protrusions in an offset manner so as to increase securement between the casing and the cables and result in better strain relief of the cables; wherein each of said printed circuit boards initially defines a plurality of through holes while later filled with the corresponding overmolded casing so as to increase retention between the printed circuit board and the casing in the lengthwise direction.

Claim 6

A cable assembly comprising: an insulating housing; a plurality of circuit boards juxtaposed in the insulating housing, each circuit board extending along a lengthwise direction while the circuit board side by side arranged with one another along a lateral direction, each circuit board having a rear edge portion; a plurality of sets of cables being arranged in a matrix manner on a lateral plane, each set being commonly mounted on the rear edge portion of each of the circuit boards; and a plurality of casings being respectively overmolded onto the individual circuit boards and encasing therein the rear edge portion of the circuit board and corresponding cables; further comprising a fastening means, and wherein each casing defines a through-hole for insertion of the fastening means; wherein each of said casings defines openings and protrusions on two opposite surfaces so as to allow said casings side by side stacked to each other under a condition that the protrusions of one casing are received in the corresponding openings of the adjacent casing; wherein in each of the casings portions of the cables around the corresponding protrusions are deflected toward the corresponding protrusions in an offset manner so as to increase securement between the casing and the cables and result in better strain relief of the cables; wherein each of said printed circuit boards initially defines a plurality of through holes while later filled with the corresponding overmolded casing so as to increase retention between the printed circuit board and the casing in the lengthwise direction.
