Electrical terminal assembly
View Patent ↗An electrical terminal assembly includes a base having a body including a first end and a second end. First and second opposed base beams extend from the first end of the body in a first direction. A spring clamp has a clamp base and first and second opposed spring beams extending from the clamp base in the first direction and disposed over the first and second base beams biasing the first and second base beams toward one another. The body of the base is configured to permit the spring clamp to be inserted onto the base in a second direction normal the first direction.
1. An electrical terminal assembly comprising:
a base including a body having a first end and a second end, wherein first and second opposed base beams extend from the first end of the body in a first direction; and
a spring clamp having a clamp base and first and second opposed spring beams extending from the clamp base in the first direction and disposed over the first and second base beams so as to bias the first and second base beams toward one another, wherein the body of the base is configured to permit the spring clamp to be inserted onto the base in a second direction that is normal to the first direction.
2. The electrical terminal assembly of claim 1 , wherein the spring clamp is resiliently configured such that the first and second spring beams may be deflected away from one another, permitting the spring clamp to be moved over the body of the base along the second direction during an assembly process of the electrical terminal assembly.
3. The electrical terminal assembly of claim 1 , wherein the base includes an integrally formed locking feature that prevents the removal of the spring clamp from the base along the second direction.
4. The electrical terminal assembly of claim 3 , wherein the locking feature further prevents movement of the spring clamp relative to the base in a lateral direction that is normal to the first direction.
5. The electrical terminal assembly of claim 4 , wherein the locking feature is an outwardly extending tab that engages with the spring clamp.
6. The electrical terminal assembly of claim 3 , wherein the locking feature is an elongated latch that traps portions of the spring clamp between the latch and a rear end of the body of the base.
7. The electrical terminal assembly of claim 6 , wherein the latch includes a tab extending from an end of the latch, and wherein the tab is disposed in a slot formed in the rear end of the body of the base, thereby securing the end of the latch to the rear end of the body.
8. The electrical terminal assembly of claim 7 , wherein the latch includes a boss formed therein and positioned adjacent the spring clamp to prevent movement of the spring clamp in the second direction.
9. The electrical terminal assembly of claim 1 , wherein the base includes one or more dome shaped protrusions that engage with surfaces of the spring clamp.
10. The electrical terminal assembly of claim 1 , wherein the spring clamp is made of a material having a higher yield strength than a material that the base is made of.
11. The electrical terminal assembly of claim 1 , wherein the spring clamp is made of steel.
12. The electrical terminal assembly of claim 1 , wherein the base is made of a high conductivity alloy.
13. A method of assembling an electrical terminal assembly comprising the steps of:
(a) providing a base including a plurality of opposed base beams extending in a first direction;
(b) providing a spring clamp including a plurality of opposed spring beams extending in the first direction; and
(c) positioning the spring clamp over the base by moving the spring clamp in a lateral direction normal to the first direction until the spring beams are positioned over the base beams, thereby assembling the electrical terminal assembly.
14. The method of claim 13 , wherein prior to step (c), opposed spring beams are deflected and spring biased away from one another to provide clearance for insertion of the spring clamp over the base.
15. The method of claim 14 , wherein the opposed spring beams are deflected by an arbor tool having first and second arbors that are movable relative to one another.
16. The method of claim 15 , wherein subsequent to step (c), the first and second arbors are retracted from the spring beams.
17. The method of claim 13 , wherein prior to step (c), tips of opposed base beams are moved toward one another.
18. The method of claim 17 , wherein the tips of the opposed base beams are moved toward one another by the use of a holding tool having a pair or arms which are movable relative to one another.
