Circuit board connection terminals

Abstract

To provide a terminal for a connection circuit board having high versatility, and capable of coping with without increasing the manufacturing cost and connecting a mating terminal without requiring specification change even when the direction of a wiring from the mating board or the extension direction of a bus bar and the orientation of the mating terminal change due to design changes, etc.SOLUTION: A bottomed cylindrical fixed casing 6 having a fixed contact 5 and an upward opening is soldered onto a circuit board 1, and a cylindrical main body 12 of a movable casing 7 is placed inside thereof from above, and the rotation about an axis L is guided. A movable contact 8 is arranged as a female terminal in the main body 12, and the mating terminal 4 of the male terminal can be connected from above. An elastic piece 9 is integrally formed by folding back from one side of a base surface portion 8a of the movable contact 8, and its tip portion 9a is brought into contact with the fixed contact 5 to maintain conduction.SELECTED DRAWING: Figure 4

Claims

1. In a connection terminal that is mounted on a circuit board and to which a mating terminal is connected, a stationary casing having stationary contacts soldered onto the circuit board; a movable casing connected to the fixed casing so as to be rotatable about an axis substantially perpendicular to the circuit board; a movable contact attached to the movable casing and capable of connecting the mating terminal from an opposite side to the circuit board; a conductive member that electrically connects the fixed contact and the movable contact regardless of an angle of the movable casing about the axis; Equipped with The movable casing has a main body portion that faces the fixed contact and is formed on the axis, and a contact accommodating chamber is formed on a surface of the main body that faces the fixed contact, The movable contact is manufactured by bending a metal plate and disposed in the contact accommodating chamber, the conductive member is elastically interposed between the movable contact and the fixed contact to electrically connect the fixed contact and the movable contact, and is configured as an elastic piece that is folded back integrally from one side of the movable contact and has a tip end elastically abutted against a position on the fixed contact in the vicinity of the axis, The fixed contact has a gas vent hole formed on the axis for use in soldering to the circuit board, The tip of the elastic piece is formed with a relief portion corresponding to the gas vent hole. A connection terminal for a circuit board.

2. the fixed casing has a bottomed cylindrical shape with the fixed contact as a bottom portion and centered about the axis, the cylindrical shape opening toward an opposite side to the circuit board, The main body of the movable casing is disposed in the fixed casing in a cylindrical shape centered on the axis, the movable casing has an outer peripheral surface of the main body in sliding contact with an inner peripheral surface of the fixed casing, and is guided in rotation about the axis, while an opposing surface of the main body faces the fixed contact at a predetermined interval to define a conductive chamber; The conductive member is disposed in the conductive chamber.

2. The connection terminal for a circuit board according to claim 1.

3. The escape portion of the elastic piece is formed by cutting out a tip side of the elastic piece, The tip end of the elastic piece is divided into two by the recess and abuts on the fixed contact on both sides of the gas vent hole.

3. The connection terminal for a circuit board according to claim 2.

4. A plurality of hooks are formed on the outer periphery of the movable casing so as to surround the fixed casing, The hooks are hooked to the stationary casing from the outer periphery thereof to prevent the main body of the movable casing from coming out of the stationary casing.

4. The connection terminal for a circuit board according to claim 2 or 3.
