Abstract

A method of assembling an electrical terminal having a base and a spring member. The base is provided with a plurality of base beams. The spring member is provided with a plurality of spring beams. The spring member defines an axis such that the plurality of spring beams is spaced radially apart from the axis. The spring beams deflected radially outwardly. The base is inserted in the spring member to position the base beams adjacent to the spring beams. The spring beams are released such that the spring beams retract radially inwardly against the base beams.

First claim

What is claimed is:

1. A method of assembling an electrical terminal assembly comprising:
a. providing a base including a plurality of base beams;
b. providing a spring member including a plurality of spring beams, wherein the spring member defines an axis such that the plurality of spring beams are spaced radially apart from the axis;
c. deflecting the spring beams radially outwardly;
d. inserting the base in the spring member to position the base beams adjacent to the spring beams; and
e. releasing the spring beams such that the spring beams retract radially inwardly against the base beams, thereby assembling an electrical terminal assembly.

2. The method of claim 1 , wherein in step (c), an arbor is inserted along the axis to deflect the spring beams radially outwardly.

3. The method of claim 2 , wherein in step (e), the arbor is removed permitting the spring beams to retract radially inwardly against the base beams.

4. The method of claim 2 , wherein each of the base beams include a slot formed therein to define a pair of adjacent spring beams.

5. The method of claim 4 , wherein the arbor includes a plurality of ribs such that a rib extends into each of the slots between the pair of adjacent base beams when the base is inserted into the spring member in step (d).

6. The method of claim 5 , wherein the plurality of ribs act against the plurality of spring beams deflecting the spring beams radially outwardly in step (c).

7. The method of claim 6 , wherein each of the ribs includes a ramped surface which engage with tip portions of the spring beams.

8. The method of claim 7 , wherein each of the tip portions is curved.

9. The method of claim 1 , wherein the base and spring member are provided with integrally formed securing features to prevent axial movement of the base relative to the spring member.

10. The method of claim 9 , wherein the base is provided with a radially outwardly extending tab that engages with an edge of an opening formed in the spring member when the base is inserted into the spring member in step (d) to prevent the movement of the spring member relative to the base along a first axial direction.

11. The method of claim 10 , wherein the spring member is provided with a radially inwardly extending finger that engages with an edge of a slot formed in the base when the base is inserted into the spring member in step (d) to prevent the movement of the spring member relative to the base along a second axial direction opposite the first axial direction.

12. The method of claim 1 , wherein the spring member is made of a material having a higher yield strength than material that the base is made of.

13. The method of claim 12 , wherein the spring member is made of steel.

14. The method of claim 12 , wherein the base is made of a high conductivity alloy.

15. The method of claim 1 , wherein the base and the spring member have a box-like shape, and wherein the spring member has four spring members which bias four base members in a radially inwardly direction when the electrical terminal assembly is assembled.
