Thus, when clamped nipple 34,35 connected and inserts holder 32 and guide anion joint 34 to its normal insertion position simultaneously, as contacting with holder 32 edge of opening 32a, protuberance 72 was deformed.So the insertion force that guide portion 71 is inserted holder 32 is reduced, the result is that clamped nipple 34,35 can be easy to connect and holder 32 openings can be easy to sealing.＜the 5 embodiment 〉
Referring to 5th embodiment of Fig. 8 explanation according to this hair line end syndeton.
Though the elastic component 20 that is contained in the 2nd embodiment on the female terminal fitting 34 closely contacts with jut 33 inner surfaces, but the inner surface of the protuberance 82 that present embodiment guide portion 81 guide ends form becomes zigzag on whole circumference, to form as shown in Figure 8 the space 83 20 of the inner surface of protuberance 82 and elastic components.Space 83 is separated by circular direction projection 82a, and projection 82a extends internally from jut, and single with it particularly or formation integrally is towards C shape elastic component 20, owing to form the star configuration.Because other structure is similar or identical with the 2nd embodiment, or components identical corresponding with identical label institute surface no longer are illustrated.
Thus, when clamped nipple 34,35 connected and inserts holder 32 and guide female terminal fitting 34 to its normal insertion position simultaneously, as contacting with holder 32 edge of opening 32a, jut 82 was deformed.So being similar to the 4th embodiment is reduced the insertion force of guide portion 81 insertion holders 32.In addition, because this inner surface toothing, holder 32 openings have prevented when being sealed by the caused strain of jut 82 transformations.＜the 6 embodiment 〉
The 6th embodiment of wire end connection construction of the present invention is described referring to Fig. 9.
Though the guide portion 24 of the 1st embodiment has the guide end of its taper, the guide portion 41 of the 6th embodiment has the protuberance 42 that forms at its guide end.
Specifically as shown in Figure 9, guide portion 41 forms like this, and the leader that its diameter is slightly smaller than holder internal diameter and its outer surface protrudes on whole circumference outward.This protuberance 42 has circle or ellipse or annular, and the most external diameter of projection is a bit larger tham the holder internal diameter.In other words, when guide portion 41 was inserted holder, protuberance 42 was compressed, and it is contacted closely with the holder inner surface.In addition, the inclined surface in protuberance 42 front sides forms guiding surface 42a.When female terminal fitting departed from its normal insertion position, guiding surface 42a contacted with the holder edge of opening, so guide this female terminal fitting to normal insertion position.Because other structure is similar or identical with the 1st embodiment, to no longer being illustrated with the represented corresponding or components identical of identical label.
Be similar to the 1st embodiment thus, clamped nipple can be easy to reliable connection.In addition, because the holder opening also can be by protuberance 42 waterproof sealings, sealing property is able to further raising.＜the 7 embodiment 〉
