Abstract

A sealable connector assembly for terminating a multiconductor cable, such as used for connecting electronic surgical instruments to devices for providing drive signals and analyzing return signals, comprises a body terminating in a flange having a planar distal edge. A cap member placed over the flange includes a planar gasket sealing to the planar edge of the flange, and secured to the connector by a locking member.

Dependent claims

A sealable connector assembly for terminating a multi-conductor cable, comprising:

a body, defining an internal volume, and defining a first aperture in communication with said internal volume, through which first aperture extend a plurality of connecting pins, for mating connection with a like plurality of pins on a mating device, said first plurality of connecting pins lying generally in a plane, and said aperture being surrounded by an upstanding flange, said flange having a continuous distal edge lying in a second plane parallel to the plane of said first plurality of connecting pins;
a cable strain relief sealed to said body at a second aperture extending through said body into said internal volume at a location spaced from said first aperture;
a multi-conductor cable extending through and sealed to said cable strain relief, and comprising a number of conductors connected to said first plurality of connecting pins;
a cap assembly adapted to be secured to said body to provide a seal around said distal edge of said flange, said cap assembly comprising:
a substantially rigid cover member defining a recess having a planar bottom surface of dimensions exceeding the dimensions of said flange in said second plane;
a resilient gasket fitting within said recess in said cover member, for sealingly engaging said distal edge of said flange;
and
means for retaining said gasket in said recess;
and means for urging said cap assembly into sealing engagement with said body, without requiring relative rotation of said cap with respect to said body, such that said gasket is compressed against said distal edge of said flange, sealing said first plurality of pins and the internal volume of said body;
said means for urging said cap assembly into sealing engagement with said body comprising an elongated control element extending through said body, wherein a distal end of said control element is adapted to be secured to said cap assembly and a proximal end of said control element extends out of said body through a third aperture spaced from said first and second apertures, means for sealing said control element to said body at said third aperture, and hand-actuable means operatively connected to said proximal end of said control element for operating said control element to urge said cap assembly into sealing engagement with said body.
