Wire cable assembly having a terminal with an encapsulated wire end

A wire cable assembly (100) includes a terminal (108) having a termination segment (110) attached to an end of a wire cable (102), a connection segment (112) configured to attach to a mating terminal, and a transition segment (114) intermediate the termination segment (110) and the connection segment (112). The transition segment (114) of the terminal (108) has a generally rectangular cross section and a recess (120) defined in at least one distal edge (118a) and preferably both distal edges (118b) of the transition segment (114). The recess (120) may alternatively be characterized as a concavity, notch, hollow, or indentation. A sealant (124) is applied to the transition segment (114) and a sleeve (122) encloses at least a portion of the termination segment (110), the end of the wire cable (102), and at least a portion of the transition segment (114). The sealant (124) fills the recess(es) (120) and blocks a leak path between the sleeve (122) and the distal edge (118). The sleeve (122) may be a section of dual wall heat shrink tubing.
