Vertically oriented electrical contact with symmetric upper and lower resilient contacting arms
View Patent ↗An electrical contact is stamped from sheet metal and includes a planar main body, a resilient upper contacting arm extending from an upper end of the main body and a resilient lower contacting arm extending from a lower end of the main body. The upper contacting arm includes an upper oblique section and an upper contacting section at a free end thereof, and the lower contacting arm includes a lower oblique section and a lower contacting section at the free end thereof. The width of the contacting arm is similar to that of the main body while the width of the contacting section is smaller than one half of that of the main body.
1. An electrical contact comprising:
a planar main body extending in a vertical plane defining opposite upper and lower ends in a vertical direction, and opposite first and second lateral sides in a transverse direction perpendicular to the vertical direction;
a resilient upper contacting arm extending upwardly from the upper end of the main body and including an upper oblique section and an upper contacting section at a free end thereof;
a resilient lower contacting arm extending downwardly from the lower end of the main body and including a lower oblique section and a lower contacting section at a free end thereof;
a first retaining section extending from the first lateral side of the main body with an obtuse angle therebetween; and
a second retaining section extending from the second lateral side in a coplanar manner; wherein
a width of the first retaining section is larger than that of the second retaining section, and an extension downwardly extends from the first retaining section in the vertical direction; and
the upper contacting section is offset from a centerline of the upper oblique section toward a lateral side of the upper oblique section closer to the second retaining section in the transverse direction than to the first retaining section and the lower contacting section is offset from a centerline of the lower oblique section toward a lateral side of the lower oblique section closer to the second retaining section in the transverse direction than to the first retaining section.
2. The electrical contact as claimed in claim 1 , wherein each of the first retaining section and the second retaining section has a chamfer at a respective upper edge thereof.
3. The electrical contact as claimed in claim 1 , wherein the upper contacting arm and the lower contacting arm are symmetrically arranged with each other with respect to the main body.
4. The electrical contact as claimed in claim 1 , wherein a width of the upper contacting section is smaller than that of the main body, and a width of the lower contacting section is smaller than that of the main body.
5. The electrical contact as claimed in claim 4 , wherein the upper oblique section includes an inner portion linked to the main body and having a same width as the main body, and an outer portion having a tapered configuration and linked between the upper contacting section and the inner portion.
6. The electrical contact as claimed in claim 4 , wherein the lower oblique section includes an inner portion linked to the main body and having a same width as the main body, and an outer portion having a tapered configuration and linked between the lower contacting section and the inner portion.
