High voltage hermetically sealed connector

In a high voltage connector plug for terminating coaxial cable, of the plug type having a frustoconical profiled forward portion having first contact means therein connected to a cable center conductor;

• the plug being intended for mating engagement with a receptacle member having a blind bore of complementarily tapered profile in a forward face for receiving the plug forward portion therein, second contact means in said bore mateable with said plug first contact means, and conductive collar means secured to a forward end of said receptacle member and having a flared portion diverging outwardly from said forward receptable face, the improvement to said connector plug comprising:
• a rearward plug portion connected to a metallic outer shield of the cable;
• an integral annular flange portion between said forward and rearward plug portions having frontwardly, rearwardly, and outwardly facing surfaces;
• conductive coating means over said plug rearward portion and over said flange rearwardly and outwardly facing surfaces;
• pressuring means engaging against said plug flange rearward surface for axially pressuring said plug forward portion against a rearward wall within said receptacle bore, whereby,
• said plug forward portion flexes outwardly to conform to the interior dimension and profile of the receptacle bore, and, upon continued application of said pressuring means, said plug flange is compressed against said receptacle forward face, and influences said outward plug flange surface progressively into engagement against said flared collar portion of the receptacle.

In a high voltage connector receptacle intended for mating with a plug member, the plug member having a frustoconical profiled forward portion having first contact means therein;

• an annular flange intermediate portion having an outwardly facing surface provided with conductive coating means thereon;
• and pressuring means;
• the receptacle comprising:
• a body having a blind bore therein of dimensioned diameter from a forward face for receiving the plug forward portion therein with clearance, said body having a rearward wall within said bore;
• second contact means within said rearward wall for matingly engaging said plug first contact means;
• conductive collar means peripherally secured to a forward end of said body and having a flared portion diverging outwardly from said forward body face, and having external means for engaging said pressuring means, whereby,
• upon receipt of the plug forward portion into said receptacle blind bore and application of said pressuring means, said plug forward portion is pressured against said rearward receptacle wall and flexes outwardly to conform to the interior dimension and profile of the receptacle bore, and, upon continued application of said pressuring means, said plug flange is compressed against said receptacle forward face, and influences said outward plug flange surface progressively into engagement against said flared collar portion of said receptacle.
