Abstract

A solderable electric connector formed of a metal sheet as a single body includes a flat bottom portion soldered to a conductive pattern of a printed circuit board (PCB), an elastic fastening portion bent and extended from one end of the bottom portion in a longitudinal direction thereof, and a first housing vertically bent and extended from one end of the bottom portion in a width direction and surrounding the elastic fastening portion. Herein, a front end of the first housing is vertically bent downwards and forms a supporting plate and a penetration hole is formed in a certain location on the supporting plate. Also, a pressurizing projection projects from a top surface of the elastic fastening portion and a metal core of a wire passing through the penetration hole is pressurized between the pressurizing projection and a bottom surface of the first housing and coupled therewith.

Claims

1. A solderable electric connector formed of a metal sheet as a single body, the electric connector comprising:

a flat bottom portion soldered to a conductive pattern of a printed circuit board (PCB);

an elastic fastening portion bent and extended from one end of the bottom portion in a longitudinal direction thereof; and

a first housing vertically bent and extended from one end of the bottom portion in a width direction and surrounding the elastic fastening portion,

wherein a front end of the first housing is vertically bent downwards and forms a supporting plate and a penetration hole is formed in a certain location on the supporting plate, and

wherein a pressurizing projection projects from a top surface of the elastic fastening portion and a metal core of a wire passing through the penetration hole is pressurized between the pressurizing projection and a bottom surface of the first housing and coupled therewith.

2. The solderable electric connector of claim 1, further comprising a second housing vertically bent and extended from another end of the bottom portion in the width direction, bent toward a top of the elastic fastening portion, and in contact with the bottom surface of the first housing to be overlapped therewith.

3. The solderable electric connector of claim 1, wherein the pressurizing projection is formed by cutting off and pressing a part of the elastic fastening portion from a bottom surface thereof to project from the top surface, and

wherein an end of the pressurizing projection is formed with one or more teeth in contact with the metal core of the wire.

4. The solderable electric connector of claim 1, wherein a top surface of the first housing provides a pickup area for a vacuum pickup.

5. The solderable electric connector of claim 4, wherein the solderable electric connector is reel-taped to be surface-mounted on the conductive pattern by vacuum picking up on the pickup area and to be reflow-soldered thereto.

6. The solderable electric connector of claim 2, wherein a front end of the second housing is partially cut off at both ends in a width direction and vertically bent downwards to form a guide having a reverse U shape, and

wherein a space between sidewalls of the guide is formed to be greater than the penetration hole of the supporting plate.

7. The solderable electric connector of claim 1, wherein a diameter of the penetration hole is formed only to allow the metal core of the wire to pass therethrough.

8. A surface-mountable electric connector, which is solderable and formed of a metal sheet as a single body, the electric connector comprising:

a flat bottom portion soldered to a conductive pattern of a PCB;

an elastic fastening portion bent and extended from one end of the bottom portion in a longitudinal direction thereof; and

a housing comprising a first housing vertically bent and extended from one end of the bottom portion in a width direction and bent toward a top of the elastic fastening portion and a second housing vertically bent and extended from another end of the bottom portion in the width direction, bent toward the top of the elastic fastening portion, and in contact with a top surface of the first housing to be overlapped therewith,

wherein a top surface of the second housing provides a pickup area for a vacuum pickup, and

wherein the elastic fastening portion is formed with a fastening device, to which a plug fixed to a wire and electrically connected to a metal core of the wire is attached to be detachable.

9. The surface-mountable electric connector of claim 8, wherein a pair of contact guides extended in the longitudinal direction project from a bottom surface of the first housing, on which the first housing is overlapped with the second housing.

10. The surface-mountable electric connector of claim 9, wherein the contact guide is formed by press-inserting the top surface of the first housing.

11. The surface-mountable electric connector of claim 9, wherein both ends of the contact guide are tapered.

12. The surface-mountable electric connector of claim 8, wherein the fastening device is one of a hitching hole formed in the elastic fastening portion and a hitching projection projecting from the elastic fastening portion toward the first housing.

13. The surface-mountable electric connector of claim 12, wherein the hitching projection is formed by cutting off a part of the elastic fastening portion in the width direction and press-inserting an adjacent portion to a cutting line from a bottom surface of the elastic fastening portion.

14. The surface-mountable electric connector of claim 8, wherein the electric connector is reel-taped to be surface-mounted on the conductive pattern by picking up on the pickup area and reflow-soldered thereto.

15. An electric connector assembly comprising:

an arm connector comprising a flat bottom portion soldered to a conductive pattern of a PCB, an elastic fastening portion bent and extended from one end of the bottom portion in a longitudinal direction thereof and formed with a fastening device, and a housing comprising a first housing vertically bent and extended from one end of the bottom portion in a width direction and bent toward a top of the elastic fastening portion and a second housing vertically bent and extended from another end of the bottom portion in the width direction, bent toward the top of the elastic fastening portion, and in contact with a top surface of the first housing to be overlapped therewith; and

a plug formed of a metal sheet as a single body, fixed to a wire, and electrically connected to a metal core of the wire,

wherein the plug is inserted into the arm connector and is coupled with the fastening device to be physically separable.

16. The electric connector assembly of claim 15, wherein the fastening device is one of a hitching hole formed in the elastic fastening portion and a hitching projection projecting from the elastic fastening portion toward the first housing, and

wherein the plug is formed with one of a hitching projection and a hitching hole corresponding to the hitching hole and the hitching projection.
