Abstract: A structure for preventing looseness of an electrical connector comprises a first connector housing, a second connector housing having a hood for accommodating the first connector housing, a locking projecting portion mounted on a locking arm which is formed at the first connector housing, and a locking hole formed at the hood so as to be engaged with the locking projecting portion. The first connector housing and the second connector housing are coupled with each other wherein the locking projection has taper portions so as to become progressively smaller in projecting direction of a main body like a square pole at both side walls locating in the coupling direction. A spacing between both lower edges of said taper portions is set to be approximately equal to a spacing between both inner wall surfaces locating in an orthogonal direction to coupling direction at the locking hole.

Abstract: There is disclosed an LIF connector in which a reverse insertion of a slider can be detected rapidly and easily although the connector has a simple construction. The LIF connector includes an LIF (low insertion force) mechanism in which a slider is slidable over a first connector through guides, and by sliding the slider, a second connector can be inserted into and withdrawn from the first connector. A pair of retractable projections are provided respectively on opposed side walls of the slider, and each of the projections has an inclined surface and a substantially vertical abutment surface. When the slider is inserted with directions of its front and rear ends kept proper, the inclined surface is brought into sliding contact with the associated guide to thereby retract the projection. When the slider is inserted with the directions of its front and rear ends reversed, the abutment surface abuts against the associated guide to thereby prevent the insertion of the slider.

Abstract: There is disclosed an LIF (low insertion force) connector in which a slider can be positioned with a simple construction, and an insertion/withdrawal force, required for inserting and withdrawing a connector relative to a mating connector, can be reduced, and wear and deformation of a slider-retaining portion can be positively prevented. In the LIF connector, a driven shaft of a second connector is inserted into a through hole formed in a first connector, and a slider, having cam grooves, is slid over the first connector to linearly move the driven shaft, thereby inserting and withdrawing the second connector relative to the first connector. A retaining projection, which stops the sliding movement of the slider, and positions inlets of the cam grooves relative to the through hole in the first connector, is formed on the first connector at a substantially rearmost end of an extent of sliding movement of the slider.

Abstract: There is disclosed a connector construction in which the operability in the insertion and withdrawal of a connector is greatly enhanced, and an installation space is reduced, and the rigidity is increased, and the number of component parts is reduced, thereby simplifying the construction. An LIF connector includes a first connector, a second connector for being inserted into and withdrawn from the first connector, and a slider for inserting and withdrawing the second connector relative to the first connector. The first connector includes a reception portion for receiving the second connector, and a through hole communicating with the reception portion. The second connector includes a driven shaft for being inserted into the through hole in the first connector, and guide pins projecting perpendicularly from the driven shaft.

Abstract: Pivot shafts are formed on a female connector, and male and female connectors are fitted together by pivotally moving an operating lever pivotally mounted on the pivot shafts. The operating lever has shaft-receiving grooves for respectively receiving the pivot shafts, and includes retaining portions formed integrally with this operating lever, and each of the retaining portions has a flat or curved abutment surface which is in line-contact with the associated pivot shaft received in the shaft-receiving groove, thereby retaining the pivot shaft in the shaft-receiving groove.

As a result of a movement of the slide members, guide pins provided on the male connector is guided by guide grooves provided on the slide members to pull the male connector into the hood assembly, thereby fitting the connectors to each other. A hood portion of the female connector is inserted between upper and lower flanges of the hood assembly with anchoring holes provided on the hood assembly and anchoring projections provided on the female connector in positions shifted from each other, and the hood assembly and the female connector are slid in this state into a normal position where the anchoring projections engage the anchoring holes.

Abstract: Slide members 43 are provided on the upper and lower portions of a hood section 27 of a male connector 25 so that the slide members 43 are movable in Y direction orthogonal with X direction in which the male connector 25 is engaged with a female connector 35. Guide grooves which are slanted in mutually opposite directions in the sliding direction are provided on the inner surface side at which the slide members 43 face each other. Guide pins 37a and 37b guided to the guide grooves are provided on the upper and lower portions of the female connector 35. An operation lever 47 which can rotate around rotation supporting pins 57a is provided at one end of the upper and lower slide members 43. Since the upper and lower slide members 43 move in mutually opposite directions by the rotation of the operation lever 47, the female connector 35 is drawn into the hood section 27 of the male connector 25 when the slide members 43 and 45 slide in the mutually opposite directions.

Abstract: There is provided a connector fitting apparatus which can fit a female connector and a male connector to each other by taking advantage of a cam thrust force generated by swinging a lever member. In the fitting apparatus, a cover 23 is used as the lever member, and is formed with an opening 41 so as to be swingable to an electric wire withdrawal side of a female connector 25. When the cover is swung in the above manner, the electric wire withdrawal side is protected by the cover 23, and then, accompanying with the swing of the cover 23, an electric wire 29 is bent and oriented to a wiring direction, thus being led to the outside from the opening 41.

Abstract: A wound core is formed by winding thread rubber (13) on a center (11) by holding the center (11) among three winding rollers (12), driving at least one winding roller to rotate the center, and feeding thread rubber (13) to the rotating center through a brake roller (16) and a delivery roller (14), thereby winding the thread rubber on the center under tension. The tension of thread rubber (13) is continuously measured upstream of the center by a tension gauge (42). The rotating condition of at least one of the winding roller (12), brake roller (16), and delivery roller (14) is adjusted in accordance with the tension measurement for adjusting the winding tension while winding the thread rubber on the center. When the tension of thread rubber is changed continuously or stepwise during winding, a wound core in which the hardness of the thread rubber layer varies continuously or stepwise in an thickness direction can be produced.
