Terminal structure

1. A terminal structure in which a first terminal is insertable in a second terminal,

the first terminal comprising:

a pin; and

a first rotor provided at an end of the pin,

the second terminal comprising:

a female pin including a receptacle in which the pin is insertable;

a hollow elastic member contained in the receptacle and rotatable along an inner circumferential face of the receptacle; and

a second rotor provided at an end of the elastic member,

the pin and the first rotor being configured to be inserted in the elastic member when the pin and the first rotor are moved in an insertion direction,

the first rotor having an outer circumferential face including a first contact face extending along a circumferential face of the first rotor as the first contact face extends in the insertion direction,

the second rotor including a second contact face configured to come in contact with the first contact face,

the first contact face being configured to come in contact with the second contact face when the pin and the first rotor are moved in the insertion direction,

the second rotor and the elastic member being configured to rotate circumferentially when the first rotor is moved in the insertion direction while the first contact face and the second contact face are in contact with each other.

2. The terminal structure according to claim 1 , wherein

the second rotor has a ring shape,

the second contact face is formed on an inner circumferential face of the second rotor,

the second rotor is configured to deform to stretch when the pin is inserted therein, and

while the pin is inserted in the second rotor, a gap is defined between the second rotor and an inner circumferential face of the female pin.
