Contact piece of gold finger, gold finger and connector comprising the gold finger
View Patent ↗A contact piece of a gold finger comprises: a first main body segment; a second main body segment; and a transition segment connected to the first main body segment and the second main body segment, respectively, in a vertical direction, in which an upper edge and a lower edge of the transition segment are inclined with respect to a lateral direction respectively. A gold finger and a connector comprising the same are also provided.
1. A contact piece of a gold finger, comprising:
a first main body segment;
a second main body segment; and
a transition segment connected to the first main body segment and the second main body segment, respectively, in a vertical direction,
wherein an upper edge and a lower edge of the transition segment are inclined with respect to a lateral direction respectively,
wherein a top portion of the first main body segment is non-axisymmetrical with respect to the vertical direction,
wherein the first main body segment, the second main body segment, and the transition segment are located within one plane, and
wherein the transition segment has a left edge and a right edge defined between the upper edge and the lower edge, at least one of the left edge and the right edge being curved within the plane.
2. The contact piece of the gold finger according to claim 1 , wherein the first main body segment, the second main body segment, and the transition segment are an integral piece.
3. The contact piece of the gold finger according to claim 1 , wherein a first angle α is formed between the upper edge of the transition segment and the lateral direction, and a second angle β is formed between the lower edge of the transition segment and the lateral direction, in which 30°≦α≦70°, and 30°<β<70°.
4. The contact piece of the gold finger according to claim 1 , wherein the transition segment has the left edge and the right edge, both of which are curved.
5. The contact piece of the gold finger according to claim 1 , wherein the transition segment has the left edge and the right edge, one of which is curved and the other of which is straight.
6. The contact piece of the gold finger according to claim 4 , wherein each curved edge is formed by a plurality of arc segments.
7. The contact piece of the gold finger according to claim 6 , wherein each arc segment has a radius of about 0.10-0.15 mm.
8. A gold finger comprising a plurality of contact pieces spaced apart from each other in a lateral direction, each contact piece comprising:
a first main body segment;
a second main body segment; and
a transition segment connecting the first main body segment and the second main body segment in a vertical direction,
wherein an upper edge and a lower edge of the transition segment are inclined with respect to the lateral direction respectively,
wherein a top portion of the first main body segment is non-axisymmetrical with respect to the vertical direction,
wherein the first main body segment, the second main body segment, and the transition segment are located within one plane, and
wherein the transition segment has a left edge and a right edge defined between the upper edge and the lower edge, at least one of the left edge and the right edge being curved within the plane.
9. A connector, comprising:
a substrate; and
a gold finger comprising a plurality of contact pieces spaced apart from each other in a lateral direction, each contact piece comprising:
a first main body segment;
a second main body segment; and
a transition segment connecting the first main body segment and the second main body segment in a vertical direction,
wherein an upper edge and a lower edge of the transition segment are inclined with respect to the lateral direction respectively,
wherein a top portion of the first main body segment is non-axisymmetrical with respect to the vertical direction,
wherein the first main body segment, the second main body segment, and the transition segment are located within one plane, and
wherein the transition segment has a left edge and a right edge defined between the upper edge and the lower edge, at least one of the left edge and the right edge being curved within the plane.
