Abstract

A pad includes a retaining portion and a soldering portion. The retaining portion has a through hole running therethrough in a thickness direction of the metal sheet and four side edges perpendicular to the metal sheet. The soldering portion extends from a first side edge of the retaining portion. The whole of the pad is electroplated except two opposite third and forth side edges of the retaining portion which connect with opposite ends of the first side edge.

Claims

1. A pad made from a metal sheet, comprising:

a retaining portion having a through hole running therethrough in a thickness direction of the metal sheet, the retaining portion having opposite first and second edges and opposite third and fourth edges commonly perpendicular to the metal sheet;

a soldering portion extending from a first side edge of the retaining portion;

wherein

the whole of the pad is electroplated except two opposite third and forth side edges of the retaining portion which connect with opposite ends of the first side edge.

2. The pad as claimed in claim 1, wherein a second side edge of the retaining portion is opposite to the first side edge and connects with one ends of the third and forth side edges, the second side edge is of a straight line.

3. The pad as claimed in claim 2, wherein the third and forth side edges respectively has a barb projecting therefrom to and a recess is defined at a root of the barb.

4. The pad as claimed in claim 3, wherein the soldering portion extends away from the first side edge and then bends reversely.

5. The pad as claimed in claim 1, wherein the soldering portion extends perpendicular to the retaining portion.

6. The pad as claimed in claim 1, wherein said first edge and said second edge are parallel to each other, and said third edge and said fourth edge are parallel to each other.

7. An assembly method of pads to electrical connectors, comprising:

preparing a unity metallic strip;

stamping a plurality of pads on the strip along an extending direction of the strip, the pads integrally connecting with each other by connecting portions in the extending direction, each pad including a retaining portion with a through hole thereof and a soldering portion extending from the retaining portion;

electroplating the stamping strip;

the pads being transported to a pre-determinated position which detects by the through holes and then being inserted to the electrical connectors.

8. The assembly method of pads to electrical connectors as claimed in claim 7, wherein cutting off the connection portions to get one single pad which is inserted in to one receiving room of one electrical connector, the pad has a pair of opposite side edges exposing without any plated layer.

9. The assembly method of pads to electrical connectors as claimed in claim 8, wherein the pair of side edges has barbs interfering with the receiving room.

10. The assembly method of pads to electrical connectors as claimed in claim 9, wherein the retaining portion defines a first side edge from which the soldering portion extends and a second side edge opposite to the first side edge and covered with plated layer wholly.

11. An mounting pad stamped from a metallic sheet for use with an electrical connector, comprising:

a planar retaining portion defining a through hole along a thickness direction and two opposite side edges; and

a pair of barb structure formed on the two opposite side edges under condition that an upper region and a lower region of each of said side edges are respectively located by two sides of the corresponding barb structure and originally, in temporary situation of a manufacturing process, connected to a linking carrier structure which links the mounting pad and a neighboring mounting pad before the mounting pad is separated from a neighboring mounting pad;

wherein

a layer is plated upon the whole mounting pad except said upper region and the lower region of each of the side edges due to such plating occurring before the mounting pad is severed from the linking carrier structure.

12. The mounting pad as claimed in claim 11, wherein a soldering section unitarily extends from a bottom edge of the retaining portion.

13. The mounting pad as claimed in claim 12, wherein said soldering section is of a Z-shaped configuration.
