Abstract: A connector housing includes a housing main body formed from a first material and a latch arm formed from a second material having a lower rigidity than the first material. The latch arm extends in a cantilever form, forms a boundary portion at a connection between the latch arm and the housing main body, and is configured to elastically deform in relation to the housing main body to latch a latched member. A transition region having a continuously variable mixing ratio between the first material and the second material is present within an expanded boundary region including the boundary portion and expanding into the housing main body and into the latch arm.

Abstract: A fusible link unit which is fastened to a battery post clamp terminal clamped to an on-vehicle battery, includes: a bus bar made from a metal plate and including: a battery terminal including at least two mounting edges, and a plurality of fastening holes provided thereon and through which a fastening member of the battery post clamp terminal is inserted, each of the fastening holes corresponding to a respective one of the mounting edges; and at least one fusible portion provided at a side of the bus bar opposite to the battery terminal; and a resin case covering the bus bar except for the at least one fusible portion.
