Electrical connector and electrical connector assembly

An electrical connector, comprising:

• a conductive housing having a first receiving portion with an open end;
• a movable terminal having a first end inserted into the first receiving portion via the open end, the movable terminal having a second receiving portion;
• a first elastic piece located in a space defined by the first receiving portion and the second receiving portion, a second end of the movable terminal opposite to the first end protrudes movably out of the first receiving portion against an elasticity of the first elastic piece;
• and
• a second elastic piece provided between an inner side wall of the conductive housing and the movable terminal and located between the first end of the movable terminal and the open end of the first receiving portion, the second elastic piece having a spring sheet extending axially from a pair of opposite ends thereof toward each other, the movable terminal is electrically connected to the conductive housing by the second elastic piece.

An electrical connector assembly, comprising:

• an electrical connector including a conductive housing having a first receiving portion with an open end, a movable terminal having a first end inserted into the first receiving portion via the open end, the movable terminal having a second receiving portion, and a first elastic piece located in a space defined by the first receiving portion and the second receiving portion, a second end of the movable terminal opposite to the first end protrudes movably out of the first receiving portion against an elasticity of the first elastic piece, the first end of the movable terminal has a first elastic arm elastically abutting an inner side wall of the first receiving portion, the movable terminal being electrically connected to the conductive housing by each of the first elastic piece and the first elastic arm;
• a cylinder including an outer conductive cylinder and an inner insulation cylinder provided in the outer conductive cylinder, the electrical connector is mounted in the inner insulation cylinder and isolated from the outer conductive cylinder by the inner insulation cylinder;
• and
• a mating connector including an insulation base and a connection terminal connected to the insulation base, the connection terminal extending partially into the outer conductive cylinder and electrically connected to the outer conductive cylinder.

An electrical connector, comprising:

• a conductive housing having a first receiving portion with an open end;
• a movable terminal having a first end inserted into the first receiving portion via the open end, the movable terminal having a second receiving portion;
• a first elastic piece located in a space defined by the first receiving portion and the second receiving portion, a second end of the movable terminal opposite to the first end protrudes movably out of the first receiving portion against an elasticity of the first elastic piece, the first end of the movable terminal has a first elastic arm elastically abutting an inner side wall of the first receiving portion, the movable terminal being electrically connected to the conductive housing by each of the first elastic piece and the first elastic arm;
• and
• a tube spring provided between the inner side wall and the movable terminal and located between the first end of the movable terminal and the open end of the first receiving portion, the movable terminal is electrically connected to the conductive housing by the tube spring, the open end of the first receiving portion has a flange protruding radially inwardly and preventing the tube spring from sliding out of the first receiving portion, the first receiving portion has a stopping portion preventing the tube spring from moving away from the open end of the first receiving portion.
