Abstract

A male connector includes male terminals 22 held in a male housing 20, tubular bodies 44 projecting on the male housing 20 and surrounding male connecting portions 24 of the male terminals 22, insulating cover portions 32 for covering tip parts of the male connecting portions 24, female terminal accommodation gaps 46 formed between the male connecting portions 24 and facing surfaces of the tubular bodies 44, and female terminal accommodation holes 48 open in projecting end surfaces and side surfaces of the tubular bodies 44. The female terminal accommodation gaps 46 and the female terminal accommodation holes 48 are configured to allow insertion of female terminals 72 including female connecting portions 70 to be connected to the male connecting portions 24 in a mating female connector 14 while hindering hand contact with the male connecting portions 24.

First claim

1 . A male connector, comprising:
a male terminal held in a male housing; a tubular body projecting on the male housing and surrounding a male connecting portion of the male terminal; an insulating cover portion for covering a tip part of the male connecting portion; a female terminal accommodation gap formed between the male connecting portion and a facing surface of the tubular body; and a female terminal accommodation hole open in a projecting end surface and a side surface of the tubular body, the female terminal accommodation gap and the female terminal accommodation hole being configured to allow insertion of a female terminal including a female connecting portion to be connected to the male connecting portion in a mating female connector while hindering hand contact with the male connecting portion.

2 . The male connector according to claim 1 , wherein a part of the male connecting portion of the male terminal except the tip part is not covered by an insulating member.

3 . The male connector according to claim 1 , comprising a pair of contact preventing ribs projecting toward an outer peripheral side of the tubular body from a pair of circumferential edge parts defining the female terminal accommodation hole in the tubular body, the female terminal accommodation hole being configured to include the pair of contact preventing ribs.

4 . The male connector according to claim 1 , wherein:
the male housing includes a body portion for accommodating a base end part of the male terminal, the body portion has a female connector mounting surface on which the female connector is to be mounted, the male connecting portion of the male terminal and the tubular body surrounding the male connecting portion are provided to project in a central part of the female connector mounting surface, a male-side housing fitting portion projecting in the same direction as the tubular body is provided to project on a peripheral edge part of the female connector mounting surface, and a region between the tubular body and the male-side housing fitting portion serves as a female housing accommodating portion for accommodating a female housing of the female connector.

5 . The male connector according to claim 4 , wherein:
a projecting dimension of the male-side housing fitting portion from the female connector mounting surface is larger than projecting dimensions of the male connecting portion and the tubular body from the female connector mounting surface, and the male-side housing fitting portion is fit to a female-side housing fitting portion provided in the female housing, whereby the female terminal of the female connector is positioned in the female terminal accommodation gap and the female terminal accommodation hole.

6 . A connector device, comprising:
a male connector according to claim 1 ; and a female connector to be connected to the male connector, wherein: the female connector includes a female terminal including a female connecting portion to be connected to the male connecting portion of the male terminal and a female housing for accommodating the female terminal, and the female housing includes a male connecting portion inserting portion and a tubular body inserting portion and the female terminal including the female connecting portion is held positioned between the male connecting portion inserting portion and the tubular body inserting portion.

7 . The connector device according to claim 6 , wherein the female connecting portion of the female terminal and a region near the female connecting portion are accommodated in the female terminal accommodation gap and the female terminal accommodation hole provided in the male connector, and a wire connecting portion of the female terminal is accommodated outside the tubular body.

8 . The connector device according to claim 7 , wherein the female connecting portion of the female terminal is accommodated into the female terminal accommodation gap and pressed into contact with an outer peripheral surface of the male connecting portion, and a wire extending from the wire connecting portion of the female terminal extends outwardly of the female terminal accommodation hole in a direction orthogonal to a projecting direction of the tubular body.

9 . The connector device according to claim 8 , wherein:
the female terminal of the female connector includes a male terminal insertion tube portion constituting the female connecting portion by an inner surface to which the male connecting portion is to be press-fit, a pair of overlapping plate portions connected to a pair of first separated portions provided by separating one part in a circumferential direction of the male terminal insertion tube portion over an entire length in an axial direction, separated from each other and projecting outward, and a biasing means held in the female terminal for biasing the pair of overlapping plate portions in a direction to overlap the overlapping plate portions each other and holding the male terminal insertion tube portion in a diameter reduced state, the male terminal insertion tube portion is resiliently deformed in a diameter enlarging direction against a biasing force of the biasing means and the male connecting portion is allowed to be press-fit into the male terminal insertion tube portion when the male connecting portion is press-fit into the male terminal insertion tube portion, and the biasing means of the female terminal is accommodated outside the tubular body of the male connector.

10 . The connector device according to claim 8 , wherein:
the male connector is configured by using the male connector according to claim 5 , the female housing is formed with a female-side housing fitting portion to which the male-side housing fitting portion is to be fit, and when the male connector and the female connector are connected, the male-side housing fitting portion and the female-side housing fitting portion are fit, whereby the female terminal of the female connector is positioned with respect to the female terminal accommodation gap and the female terminal accommodation hole of the male connector and the male connecting portion inserting portion and the tubular body inserting portion of the female connector are positioned with respect to the male connecting portion and the tubular body of the male connector.
