Abstract: The present invention is directed to a small-size press-fit connecting pin which can be press-fitted and connected in the through-hole of a circuit board by means of a low insertion force, and an electronic device using this press-fit connecting pin. The press-fit connecting pin (10) has a shaft portion with a diameter of approximately 0.4 mm, and has a first section (42) and second section (43) (along the length of the shaft portion) whose length is less than the thickness of the circuit board (100) in which the through-hole (101) is formed. Projecting strips (45, 46) which run in the direction of length are formed on the outer surfaces of the respective sections (42 and 43). The projecting strips (45 and 46) formed on the first section (42) and second section (43) are formed in mutually different angular positions.

Abstract: A latching mechanism to latch matable electrical connectors together comprises first and second electrical connectors (10,20) for matable engagement with one another, the first connector (20) having a projection (21) engageable with a tapered section (17) of a slide (15) extending along a wall of a housing (11) of the second connector (10) when the first connector is inserted into an opening (12) of the second connector (10), the slide (15) being biased in one direction by a spring (14). The slide (15) is moved in another direction upon further insertion of the first connector (20) into the opening (12) until the projection (21) moves beyond the tapered section (17) into a recess (18) whereupon the slide (15) moves back to the one direction under the influence of the spring (14) thereby latching the connectors (10,20) together.

Abstract: A receptacle content comprises a pair of opposed leaf spring members having first spring arms provided with outer contact members and second spring arms extending along the first spring arms provided with inner contact members.An electrical connector includes a dielectric housing in which electrical receptacle contacts are arranged in rows with contact members of the contacts in the rows being staggered so that upon matable connection with a complmentary electrical connector the electrical connection between the respective electrical contacts of the matable connectors is sequentially completed.
