Electrical connector

An electrical connector for a catheter cable comprising:

• a cylindrical plug body;
• a plurality of electrically-conductive connector pins disposed at least partially within the plug body;
• and
• a first water-resistant seal disposed about a perimeter of the cylindrical plug body.

An electrical connector for a catheter, comprising:

• a receptacle portion comprising:
• a cylindrical receptacle body;
• a plurality of hollow posts extending from the cylindrical receptacle body, wherein the plurality of hollow posts are electrically insulative;
• a first plurality of electrically-conductive connector pins, wherein a first portion of each electrically-conductive connector pin of the first plurality of electrically-conductive connector pins is disposed within a respective hollow post of the plurality of hollow posts and a second portion of each electrically-conductive connector pin of the first plurality of electrically-conductive connector pins extends out of the respective hollow post of the plurality of hollow posts;
• and
• a first poka-yoke structure;
• and
• a plug portion comprising:
• a cylindrical plug body;
• a plurality of holes formed in the cylindrical plug body;
• a second plurality of electrically-conductive connector pins recessed within the plurality of holes;
• and
• a second poka-yoke structure complementary to the first poka-yoke structure,
• wherein the first poka-yoke structure and the second poka-yoke structure cooperate to facilitate proper alignment of the first plurality of electrically-conductive connector pins and the second plurality of electrically-conductive connector pins when the receptacle portion is connected to the plug portion.
