Electrical terminal
View Patent ↗An electrical terminal includes a contact portion having a contact portion base with at least three sides forming a generally polyhedron structure. The contact portion has a plurality of contact arms, with at least one of the contact arms extending from at least some of the sides. The contact arms are arranged to receive a mating electrical component such that the mating electrical component contacts at least one of the contact arms associated with each side. A spring arrangement includes a plurality of spring arms, each having a spring head in contact with at least one respective contact arm near a distal end of the contact portion for applying a force thereto in a direction toward a central axis of the terminal, thereby increasing the retention force applied to the mating electrical component.
1. An electrical terminal comprising:
a contact portion including a contact portion base having a plurality of sides and forming a polyhedron structure, the contact portion further including a plurality of contact arms, at least one of the contact arms extending from a respective one of at least three of the sides, the contact arms being arranged to receive a mating electrical component to contact each of the contact arms; and
a spring arrangement including a plurality of spring arms, each having a spring body and a spring head, at least a portion of each of the spring bodies being disposed laterally adjacent to and along a length of at least one of the contact arms such that relative lateral movement between the spring bodies and an adjacent contact arm is inhibited, each of the spring heads being in contact with at least one of the contact arms toward a distal end of the contact portion for applying a force thereto in a direction toward a central axis of the contact portion, thereby increasing a retention force applied to the mating electrical component.
2. The electrical terminal of claim 1 , wherein the contact portion has four sides and forms a generally rectangular structure.
3. The electrical terminal of claim 1 , wherein the contact portion includes a pair of the contact arms extending from a respective one of at least three of the sides and the spring arrangement includes a respective one of the spring arms corresponding to each of the pairs of contact arms.
4. The electrical terminal of claim 3 , wherein at least a portion of each of the spring bodies is disposed between a respective pair of the contact arms.
5. The electrical terminal of claim 1 , wherein the contact portion includes a single contact arm extending from a respective one of at least three of the sides and the spring arrangement includes a respective one of the spring arms corresponding to each of the contact arms, each of the spring arms including a pair of elongate members forming a respective spring body.
6. The electrical terminal of claim 5 , wherein at least a portion of each of the contact arms is disposed between a respective pair of the elongate members.
7. The electrical terminal of claim 1 , wherein the spring arrangement further includes a spring base from which each of the spring arms extends, the spring base being disposed within the contact portion.
8. The electrical terminal of claim 7 , wherein each of the spring arms extends through the contact portion.
9. An electrical terminal comprising:
a contact portion including a contact portion base having a plurality of sides and forming a polyhedron structure, the contact portion further including a respective contact arm extending from a respective one of at least three of the sides, the contact arms being arranged to receive a mating electrical component to contact each of the contact arms; and
a spring arrangement including a plurality of spring arms, each having a spring body and a spring head, at least a portion of each of the spring bodies being laterally disposed adjacent to and along a length of at least one respective contact arm such that relative lateral movement between the spring bodies and an adjacent contact arm is inhibited, each of the spring heads being in contact with at least one respective contact arm toward a distal end of the contact portion for applying a force thereto in a direction toward a central axis of the contact portion, thereby increasing a retention force applied to the mating electrical component.
10. The electrical terminal of claim 9 , wherein each of the spring arms includes a pair of elongate members forming a respective spring body, and the contact portion includes a single contact arm extending from a respective one of at least three of the sides and at least partially disposed between a respective pair of the elongate members.
11. The electrical terminal of claim 9 , wherein the contact portion includes a pair of the contact arms extending from a respective one of at least three of the sides, and at least a portion of each of the spring bodies is disposed between a respective pair of the contact arms.
12. The electrical terminal of claim 9 , wherein the contact portion has four sides and forms a generally rectangular structure.
13. The electrical terminal of claim 9 , wherein the spring arrangement further includes a spring base from which each of the spring arms extends, the spring base being disposed within the contact portion.
14. The electrical terminal of claim 13 , wherein each of the spring arms extends through the contact portion.
15. An electrical terminal comprising:
a contact portion including:
a plurality of sides forming a polyhedron structure, and
at least one contact arm extending from a respective one of at least three of the sides and arranged to receive a mating electrical component to contact each of the contact arms; and
a spring arrangement including a plurality of spring arms, each having a spring body and a spring head, each of the spring bodies being disposed adjacent to and along a length of at least one of the contact arms such that relative lateral movement between the spring bodies and an adjacent contact arm is inhibited, each of the spring heads being in contact with at least one of the contact arms toward a distal end of the contact portion for applying a force thereto in a direction toward a central axis of the contact portion, thereby increasing a retention force applied to the mating electrical component, and
wherein each of the spring arms includes a pair of elongate members forming a respective spring body, and at least a portion of each of the contact arms is disposed between a respective pair of the elongate members.
16. The electrical terminal of claim 15 , wherein the contact portion has four sides and forms a generally rectangular structure.
17. The electrical terminal of claim 15 , wherein the spring arrangement further includes a spring base from which each of the spring arms extends, the spring base being disposed within the contact portion.
