Abstract: A projection 11 of a first connector 10 is defined into three separate engagement pieces 11A, 11B, and 11C by slits S1 and S2, thereby making the engagement piece 11A longer than the other engagement pieces 11B and 11C, and forming a slope 11F with a gentler angle than an angle of the other slopes. Accordingly, force required to insert the engagement piece 11A into a plate 20A that juts in a center of a second connector 20 is lessened. Subsequently, initial force required to insert the other engagement pieces 11B and 11C into the plate 20A is also lessened.

Abstract: In the connector housing 10, a side wall opening 10W is formed which is continuous to an upper half of an opposite side wall 10S2 from the rear surface opening 10R. A tapered protrusion 10M is provided to stand upward from a lower side opening end face 10W1 of the side wall opening 10W. In the terminal 20, a tapered engaging recessed part 20M is formed in a part opposed to the tapered protrusion 10M. In one side wall 10S1 of the connector housing 10, a tapered hole 10K is formed. In the terminal 20, a tapered protrusion 20K is formed which enters the tapered hole 10K. Thus, the terminal 20 slides in a transverse direction by a sliding operation of the tapers so that the terminal 20 is held in the connector housing 10.

Abstract: For obtaining a terminal capable of being soldered to a substrate without causing trouble such as a short circuit or poor connection, a lead part 13 is plated with tin in a state joined to a joining part 42 of a carrier, and a notch part 44, whose thickness is thinned, cut by a cutter 51 from a soldering surface side for making connection to a conductor pattern is formed between the lead part 13 and the joining part 42. The notch part 44 is provided with a guide part for guiding the cutter 51 to a side of the joining part 42 and forming a fillet forming piece 17 made of a part of the notch part 44 on a side of the lead part 13 after cutting by the cutter 51.
