Latest Patents

One of his latest patents is a terminal structure for covered electric wire. This terminal structure includes a terminal portion that features a tip of a covered electric wire, along with a connection terminal that has a crimp portion crimped to the terminal portion. The design incorporates a mold resin of a hygroscopic reactive type that covers both the terminal portion and the crimp portion. The crimp portion consists of a conductive crimp portion that is crimped to the tip. The mold resin is designed with a first portion that covers the conductive crimp portion and the tip, and a second portion that covers part of the connection terminal, which is further toward the tip than the tip itself. This second portion has a thickness smaller than that of the conductive crimp portion, and a first step is formed between the first and second portions, allowing the height of the mold resin to decrease from the first portion to the second portion. Additionally, a first recess is formed on the second portion.

Another significant patent is for a terminal block that features a male connector. This male connector comprises a male-side inner housing that holds multiple male terminals, exposing their circular portions. A partition member includes a rib that divides the circular portions of the male terminals, and both the male-side inner housing and the partition member are designed to be separate from each other.
