Abstract
An encapsulating permanent wire connector is comprised of a housing provided with a first port and a second port. At least one division wall extends coaxially in a portion of the housing to a side of a straight central axis of the housing and defines an electrically isolating cavity in the housing. The housing has an opening to inject a sealing substance therein. Air evacuation holes are associated with the electrically isolating cavity for the escape of air therefrom when a sealing substance is injected within the housing with soldered wire connections being disposed in the housing and isolated from one another by the electrically isolating cavity. In a preferred embodiment, there are two spaced-apart electrically isolating cavities with a central cavity therebetween.
Claims17
An encapsulating permanent wire connector comprising a housing having a first port and a second port, at least one division wall extending coaxially in a portion of said housing to a side of a straight central axis of said housing and defining an electrically isolating cavity in said housing, an opening in said housing to inject a sealing substance therein, and air evacuation means associated with said electrically isolating cavity.
A method of interconnecting and permanently encapsulating two 3-lead wire interconnections, said method comprising the steps of:
- i) providing a housing having a first and second port, an electrically isolating cavity formed on opposed sides of a straight central axis of said housing by a pair of division walls which extend coaxially in a portion of said housing adjacent said first port, said housing having an opening therein to inject a sealing substance, and air evacuation means in said electrically isolating cavities,
- ii) passing a first of said two 3-lead wires through said housing from said first port and out said second port,
- iii) exposing an end section of said leads of said two 3-lead wires by removing an insulating sheath from an end portion thereof,
- iv) soldering common ones of said lead end portions of said two 3-lead wires together with a central one of said leads extending on a substantially straight axis and opposed ones of said soldered leads angled towards said second port in a spaced-apart relationship;
- v) placing said opposed one of said soldered leads in an open end of said second port while applying a pulling force on said first of said two 3-lead wires to orient said opposed ones of said soldered leads in a respective one of said electrically isolating cavities thereby arresting said pulling force, and
- vi) injecting said sealing substance in said housing through said opening and causing air in said electrically isolating cavities to escape through said air evacuation means whereby said sealing substance is disposed in substantially all free space in said housing to seal said space and arrest and isolate said wires and soldered leads therein.
