Electric contact spring, electric spring contact device as well as electric contact zone
View Patent ↗The invention relates to an electric contact spring having a resilient section, an assembly portion, and a transition portion. The resilient section includes a first resilient portion, a second resilient portion extending from the first resilient portion, and a third resilient portion extending from the second resilient portion. The assembly portion extends from the first resilient portion and includes a catch device. The transition portion extends downward from the assembly portion.
1. An electric contact spring comprising:
a resilient section having
a first resilient portion,
a second resilient portion extending from the first resilient portion, and
a third resilient portion extending from the second resilient portion;
a rigid electrical contacting portion extending from the third resilient portion;
an assembly portion extending from the first resilient portion and having a catch device; and
a transition portion extending downward from the assembly portion.
2. The electric contact spring according to claim 1 , further comprising a contact portion extending from the transition portion and stepped from the assembly portion.
3. The electric contact spring according to claim 2 , wherein the assembly portion and the first resilient portion, the second resilient portion and the third resilient portion move back and forth above the transition portion through a plurality of bending portions.
4. The electric contact spring according to claim 3 , wherein the plurality of bending portions includes a first bending portion connecting the first resilient portion and the assembly portion.
5. The electric contact spring according to claim 4 , wherein the plurality of bending portions includes a second bending portion connecting the first resilient portion and the second resilient portion.
6. The electric contact spring according to claim 5 , wherein the plurality of bending portions includes a third bending portion connecting the second resilient portion with the third resilient portion.
7. The electric contact spring according to claim 6 , wherein the plurality of bending portions includes a fourth bending portion connected to the third resilient portion, and forming the rigid electrical contacting portion.
8. The electric contact spring according to claim 7 , wherein the plurality of bending portions have a constant width.
9. The electric contact spring according to claim 7 , wherein the second bending portion is wider than the first bending portion.
10. The electric contact spring according to claim 9 , wherein the third bending portion is wider than the first bending portion.
11. The electric contact spring according to claim 9 , wherein the rigid electrical contacting portion and the third resilient portion are wider than the second resilient portion.
12. The electric contact spring according to claim 1 , wherein the first resilient portion is a leaf spring.
13. The electric contact spring according to claim 1 , wherein the first resilient portion is a resilient arm.
14. The electrical contact spring according to claim 1 , wherein the rigid electrical contacting portion includes a crimp, projection, or reinforcement rib on an outer surface.
