Abstract

An exemplary terminal system comprises a pin-receiving member having a lead-in for receiving a pin-shaped contact, a signal transfer zone located a first distance from the lead-in, and a power transfer zone located a second distance from the signal transfer zone. The signal transfer zone is preferably defined by opposed bumps plated in gold. The power transfer zone is preferably annular in cross-section, so as to present a large contact area, and tin-plated. The system is therefore useful for either signal transfer or power transfer applications.

Claims

1. A terminal system for electrical power transfer and electronic signal transfer, comprising:

a contact-receiving member which includes an electrical contact member having a lead-in for surroundably receiving a corresponding electrical contact, a signal transfer zone, for transferring signals between said electrical contact and said contact-receiving member, located a first distance from said lead-in, and a power transfer zone, for transferring power between said electrical contact and said contact receiving member, located a second distance from said lead-in.

2. The terminal system of claim 1 wherein said signal transfer zone is located a shorter distance from said lead-in than said power transfer zone.

3. The terminal system of claim 1 wherein said lead-in, signal transfer zone, and power transfer zone are located linearly with respect to an electrical contact inserted into said contact-receiving member.

4. The terminal system of claim 1 further comprising at least one member operative for attaching wires.

5. The terminal system of claim 1 further comprising at least one crimp tab for attaching wires to said contact member.

6. The terminal system of claim 1 further comprising a neck-down region conformed for cooperative engagement with a locking member of an insulative housing.

7. The terminal system of claim 1 wherein said contact member of said contact-receiving member has a generally cylindrical shape operative to receive a pin.

8. The terminal system of claim 1 wherein said contact member of said contact-receiving member has a generally conical shape operative to receive a pin.

9. The terminal system of claim 1 wherein said contact-receiving member is formed from a sheet of metal.

10. The terminal system of claim 1 wherein said lead-in comprises a fluted edge conformed for receiving the tip of a pin.

11. The terminal system of claim 1 wherein said signal transfer zone is formed from at least one bump in said contacts.

12. The terminal system of claim 1 wherein said power transfer zone is formed from an annular indentation.

13. The terminal system of claim 1 wherein said signal transfer zone is plated with a noble metal.

14. The terminal system of claim 1 wherein said signal transfer zone is gold-plated.

15. The terminal system of claim 1 wherein said power transfer zone is plated in tin.

16. The terminal system of claim 1 wherein said contact-receiving member is covered with a tube which covers the entire length of said contact member.

17. The terminal system of claim 1 wherein said contact member has a sharp edge to allow said contact-receiving member to be retained by a locking member in a housing.

18. The terminal system of claim 1 wherein when said power transfer zone touches said electrical contact, said signal transfer zone does not touch said electrical contact, and when said signal transfer zone touches said electrical contact, said power transfer zone does not touch said electrical contact.

19. The terminal system of claim 1 further comprising at least one member for attaching wires and a connecting member for electrically connecting said wire-attaching member to said contact member.

20. The terminal system of claim 19 wherein said connecting member is formed to provide a cross-section characterized by structural rigidity and high current capacity.

21. The terminal system of claim 19 wherein said connecting member has a B-shaped crimp.

22. A terminal system for electrical power transfer and electronic signal transfer, comprising:

a contact-receiving member which includes an electrical contact member having a lead-in for receiving a corresponding electrical contact, a signal transfer zone, for transferring signals between said electrical contact and said contact-receiving member, located a first distance from said lead-in, and a power transfer zone, for transferring power between said electrical contact and said contact receiving member, located a second distance from said lead-in.
