Electrical contact, system and method for manufacturing an electrical contact
An electrical contact includes: a first end; a second end; and a solder cup section formed at the first end. The solder cup section conductively connects to an electric component including a wire, by soldering. The solder cup section has a circumferential wall region with an upper edge defining a solder cup opening at the first end, and a solder cup base, which is arranged opposite the solder cup opening and which defines a base of the solder cup section. The electrical contact is stamped and formed from a metal sheet.
1. An electrical contact, comprising:
a first end;
a second end;
a retention barb with a pointed tip or spike protruding away from a longitudinal axis of the electrical contact; and
a solder cup section formed at the first end, the solder cup section being configured to conductively connect to an electric component comprising a wire, by soldering,
wherein the solder cup section comprises a circumferential wall region with an upper edge defining a solder cup opening at the first end, and a solder cup base, which is arranged opposite the solder cup opening and which defines a base of the solder cup section, and
wherein the electrical contact is stamped and formed from a metal sheet.
2. The electrical contact according to claim 1 , wherein the electrical contact has a male or female geometry at the second end, which is opposite the solder cup section at the first end.
3. The electrical contact according to claim 1 , wherein the solder cup base comprises an essentially round tab, which is stamped out of the metal sheet and bent towards a longitudinal axis of the electrical contact, and towards the solder cup opening.
4. The electrical contact according to claim 1 , wherein the solder cup base has a drain opening.
5. The electrical contact according to claim 1 , wherein an inspection opening is arranged in the circumferential wall region of the solder cup section.
6. The electrical contact according to claim 5 , wherein the inspection opening is formed between adjoining longitudinal edges of the metal sheet, from which the electrical contact is formed.
7. The electrical contact according to claim 1 , wherein the electrical contact is comprised of bronze.
8. The electrical contact according to claim 1 , wherein a barrier tab is arranged between the base section of the solder cup section and the second end.
9. A system, comprising:
a plurality of the electrical contact according to claim 1 ,
wherein each of the plurality of electrical contact are embedded in or inserted into a contact holder, and
wherein the contact holder comprises an electrically insulating material.
10. A method for manufacturing the electrical contact according to claim 1 , comprising:
providing a conductive metal sheet;
stamping and forming the electrical contact from the conductive metal sheet; and
obtaining a solder cup section by bending a rounded tab towards a longitudinal axis of the electrical contact.
11. The electrical contact according to claim 4 , wherein the drain opening is arranged essentially in a middle of the solder cup base.
12. The electrical contact according to claim 7 , wherein the electrical contact has a nickel, tin, and/or gold plating.
13. The method according to claim 10 , further comprising applying a plating to the electrical contact.
