Abstract

A receptacle includes: a first-direction opening configured to be inserted and pulled out by a male terminal of a plug along a first direction; a second-direction opening configured to be inserted and pulled out by the male terminal along a second direction; and a female terminal configured to come into contact with the male terminal. The female terminal includes a plurality of arm portion pairs, each of which has arm portions extending the first direction and arranged to face each other, arranged in the second direction. Each of the arm portion pairs has contact positions at which each of the arm portion pairs is configured to come into contact with the male terminal inserted from the second-direction opening. The contact positions of one of the arm portion pairs are different from the contact positions of the other arm portion pairs in the first direction.

First claim

The invention claimed is:

1 . A receptacle comprising:
a first-direction opening configured to accommodate a male terminal of a plug when the male terminal is inserted into the first-direction opening along a first insertion and pulling-out direction; a second-direction opening configured to accommodate the male terminal when the male terminal is inserted into the second-direction opening along a second insertion and pulling-out direction different from the first insertion and pulling-out direction; and a female terminal configured to come into contact with the male terminal when the male terminal is inserted into either of the first-direction opening or the second-direction opening, wherein the female terminal includes a plurality of arm portion pairs that make contact with the male terminal when the male terminal is inserted into the second second-direction opening, each of the plurality of arm portion pairs having corresponding arm portions extending the first insertion and pulling-out direction and arranged to face each other, the plurality of arm portion pairs being arranged in the second insertion and pulling-out direction, wherein the corresponding arm portions of each of the arm portion pairs are arranged to face each other across a gap configured to accommodate the male terminal when the male terminal is inserted into the first-direction opening along the first insertion and pulling-out direction or when the male terminal is inserted into the second-direction opening along the second insertion and pulling-out direction, wherein each of the plurality of arm portion pairs has contact positions configured to come into contact with the male terminal when the male terminal is inserted into the second-direction opening, and wherein the contact positions of one of the plurality of arm portion pairs are different from the contact positions of another of the plurality of arm portion pairs in the first insertion and pulling-out direction.

2 . The receptacle according to claim 1 ,
wherein the contact positions are disposed at a tip ends of the arm portions, respectively, and wherein a length of the one of the plurality of arm portion pairs in the first insertion and pulling-out direction is different from a length of the other of the plurality of arm portion pairs in the first insertion and pulling-out direction.

3 . The receptacle according to claim 1 , wherein the contact positions are respectively provided on both the arm portions facing each other and have a protruding shape facing each other.

4 . The receptacle according to claim 1 , wherein each of the plurality of arm portion pairs includes
first inclined portions configured to widen a facing distance toward the first-direction opening at end portions on a side close to the first-direction opening of the facing arm portions, and second inclined portions configured to widen a facing distance toward the second-direction opening at end portions on a side close to the second-direction opening of the facing arm portions.

5 . The receptacle according to claim 4 , wherein the second inclined portions extend from the contact positions of the arm portions toward the second-direction opening, respectively.

6 . The receptacle according to claim 4 , wherein the contact positions, the first inclined portions, and the second inclined portions are respectively continuous and formed in a bent shape.

7 . The receptacle according to claim 1 , wherein the first-direction opening and the second-direction opening are continuous and formed in a L-shaped opening.

8 . A connector comprising:
the receptacle according to claim 1 ; and a plug including the male terminal configured to be inserted into the first-direction opening or the second-direction opening.

9 . The connector according to claim 8 , wherein the male terminal includes two flat portions and an insertion end portion that connects ends of the two flat portions with a curved surface of the male terminal.
