Abstract

In one implementation, an apparatus is configured to aid in the manufacturing or assembling of electronic surface mount packages. The apparatus includes a common mode choke base configured to support a common mode choke. The apparatus includes terminal contacts coupled to the common mode choke base. The terminal contacts are aligned with wires connected to the common mode choke. The apparatus includes a support member including a wire supporting portion aligned with the wires connected to the common mode choke and a central portion configured to support the common mode choke base.

Claims

1. A method comprising:

aligning wires from a common mode choke supported by a common mode choke base with a plurality of terminal contacts coupled to the common mode choke base; and

adjusting a support member including a wire supporting portion aligned with the wires connected to the common mode choke to secure the wires with respect to the plurality of terminal contacts.

2. The method of claim 1, wherein the plurality of terminal contacts are configured to receive a wire form tool that presses the wires against the plurality of terminal contacts.

3. The method of claim 1, wherein the common mode choke base is configured to receive a push tongue that presses the wires against the common mode choke base.

4. The method of claim 1, wherein the wire supporting portion includes a friction holder configured to frictionally hold the wires in place.

5. The method of claim 1, wherein the wire supporting portion includes an adjustable tensioner configured to move an elastic portion with respect to a rigid portion.

6. The method of claim 1, wherein at least one of the plurality of terminal contacts includes a concave portion, wherein the concave portion is shaped to receive at least one of the wires.

7. The method of claim 1, wherein at least one of the plurality of terminal contacts supports the wire during a termination process, and a weld resulting from the termination process extends past and overhangs an edge of the at least one of the plurality of terminal contacts.

8. An apparatus comprising:

wires from a common mode choke supported by a common mode choke base aligned with a plurality of terminal contacts coupled to the common mode choke base; and

a support member including a wire supporting portion aligned with the wires connected to the common mode choke adjusted to secure the wires with respect to the plurality of terminal contacts.

9. The apparatus of claim 8, wherein the plurality of terminal contacts are configured to receive a wire form tool that presses the wires against the plurality of terminal contacts.

10. The apparatus of claim 8, wherein the common mode choke base is configured to receive a push tongue that presses the wires against the common mode choke base.

11. The apparatus of claim 8, wherein the wire supporting portion includes a friction holder configured to frictionally hold the wires in place.

12. The apparatus of claim 8, wherein the wire supporting portion includes an adjustable tensioner configured to move an elastic portion with respect to a rigid portion.

13. The apparatus of claim 8, wherein at least one of the plurality of terminal contacts includes a concave portion, wherein the concave portion is shaped to receive at least one of the wires.

14. The apparatus of claim 8, wherein at least one of the plurality of terminal contacts supports the wire during a termination process, and a weld resulting from the termination process extends past and overhangs an edge of the at least one of the plurality of terminal contacts.

15. A method comprising:

aligning wires from a common mode choke supported by a common mode choke base with a plurality of terminal contacts coupled to the common mode choke base; and

adjusting a support member including a wire supporting portion aligned with the wires connected to the common mode choke and a central portion configured to secure the wires with respect to the plurality of terminal contacts.

16. The method of claim 15, wherein the plurality of terminal contacts are configured to receive a wire form tool that presses the wires against the plurality of terminal contacts.

17. The method of claim 15, wherein the common mode choke base is configured to receive a push tongue that presses the wires against the common mode choke base.

18. The method of claim 15, wherein the wire supporting portion includes a friction holder configured to frictionally hold the wires in place.

19. The method of claim 15, wherein the wire supporting portion includes an adjustable tensioner configured to move an elastic portion with respect to a rigid portion.

20. The method of claim 15, wherein at least one of the plurality of terminal contacts includes a concave portion, wherein the concave portion is shaped to receive at least one of the wires.
