摘要： A male terminal fitting (1) is formed by bending a flat metal plate worked into a specified shape and includes a contact (2), a rectangular tube (4) formed to be wider than the contact (2), and a link (3) between the contact (2) and the rectangular tube (4). The link (3) is not connected with the front edge of the upper surface of the rectangular tube (4) over the entire width. Thus, bending resistance against an external force can be improved by increasing deflectability while holding down bending rigidity.

摘要： A calcium oxide dispersion liquid contains calcium oxide fine particles having a median particle diameter (volume basis) of 1 to 200 nm and a maximum particle diameter of 10 to 1,000 nm, and an organic dispersion medium. The calcium oxide dispersion liquid is produced by filling calcium oxide fine particles, an organic dispersion medium, and beads 5 to 200 μm in diameter into a container, and stirring these materials. Therefore, the calcium oxide having a small particle diameter and a high purity is homogeneously dispersed in the calcium oxide dispersion liquid.

摘要： A female connector (F) has a housing (10) with a front end and cavities (11) extend to the front end. Terminal fittings (40) are mounted in the cavities (11). A front wall (50) is mounted on the front end of the housing (10) and is formed with tab insertion holes (51) that can communicate with cavities (11). An operable surface (59A) is exposed at an end surface of the front wall (50). The front wall (50) can be moved from a full locking position to a partial locking position along the front end of the housing (10) by pushing this operable surface (59A). Portions of the end surface of the front wall (50) other than the operable surface (59A) are covered at least partly by an wall (26) of the housing (10) to limit movement of the front wall (50).

摘要： A terminal fitting has a rectangular tube (10) formed with a locking hole (19). A resilient contact piece (25) is in the rectangular tube (10) for contacting a tab of a mating terminal fitting. Displacement restricting portions (15F, 15R, 18F, 18R) are provided in the rectangular tube (10) at positions before and behind the locking hole (19) for contacting lateral edges of the resilient contact piece (25) and restricting displacement of a resilient contact piece (25) towards a tab entrance space (32). Thus, external matter that may intrude through the locking hole (19) can not cause a damaging deformation of the resilient contact piece (25).

摘要： A male terminal fitting (1) has a rectangular tube (4). A cut is made in wall of the rectangular tube (4) to form a stabilizer (20) and produces a cut hole (22). An end edge of a closing plate (21) is arranged to face the cut hole (22) and a closing piece (23) is formed at a rear-end opening of the rectangular tube (4). The closing plate (21) and the covering piece (23) substantially prevent external matter or a leading end of another male terminal fitting (1) from intruding into the rectangular tube (4).
