A contact element of unitary construction, the contact element including a plurality of contact element mating portions which are connected via serpentine portions. The contact element being used in connector modules and providing both electrical connection and mechanical retention.

High density connector module

A high voltage electrical coupling has two parts, each with spaced mating conductors, one part forming a socket shaped to receive the body of the second part. The second coupling part has an elastic, insulative support forming sleeves around its conductors and a slot between the sleeves. The first part has an insulative barrier wall extending between its conductors and fitting in the slot of the second part. Either the socket of the first coupling part or the elastic body of the second part are tapered into the socket so that the elastic body is compressed against the barrier wall as the parts are mated, thereby squeezing closed any possible air path along the surfaces of the barrier wall.

High voltage plug and receptacle

A high voltage CRT anode electrical coupling has a connector with several spring contact fingers extending from a base and an insulating ring around the connector between the base and fingers. An insulative shroud is molded around ring and base leaving the fingers unconfined.

High voltage snap on coupling

A high voltage electrical component can be insulated by placing such component into a first sleeve of preformed insulative material dimensioned to receive and telescope over the component. An internal abutment in the first sleeve positions the component for reception of both the first sleeve and component by a second sleeve of preformed insulative material dimensioned to receive and telescope over the first sleeve and component within. An internal abutment in the second sleeve further secures and centers the component and the first sleeve for subsequent encapsulation by insulative materials used with injection molding to form an outer insulative jacket. Once encapsulated within the insulative jacket the telescoping sleeves form a convoluted path outwardly from the component to the exterior of the jacket thereby minimizing high volt leakage.
