Connector having a contact with contact surfaces inclined in opposite directions
View Patent ↗[Problem(s)] A board to board connector is disclosed to provide desirable electrical connection between contacts. [Means to Solve the Problem(s)] A board to board connector according to the present invention comprises a male connector 10 and a female connector 20 . The male connector 10 comprises a pair of male contacts 100 A, 100 B and the female connector 20 comprises a pair of female contacts 200 A, 200 B. The male contacts 100 A, 100 B comprise protruding portions 109 A, 109 B which are elastically deformable, and the female contacts 200 A, 200 B comprise contact portions 208 A, 208 B which contact the protruding portion 109 A, 109 B. The contact portion 208 B comprises a first inclined surface 201 A which inclines in a direction perpendicular to another direction in which the protruding portion moves and a second inclined surface 210 B.
1. A connector for connecting a male contact to a female contact, comprising:
the male contact including an elastically deformable protruding portion at an end thereof; and
the female contact including a contact surface for contacting with the protruding portion, the contact surface elongated in a direction in which the protruding portion moves during slideable insertion or removal, the contact surface including a first inclined surface which inclines in a first direction different form the direction of the movement of the protruding portion and a second inclined surface which inclines in a second direction opposite to the first direction, the first inclined surface and the second inclined surface are formed continuously and slope is provided at a step between the first inclined surface and the second inclined surface.
2. The connector according to claim 1 , wherein an inclination angle of the first inclined surface is equal to the inclination of the second inclined surface.
3. The connector according to claim 1 , wherein the first inclined surface and the second inclined surface are spherical shaped.
4. The connector according to claim 1 , wherein a pair of the female contacts are disposed oppositely, and the pair of the male contacts are disposed such that the pair of the protruding portions are contacted with the pair of the contact surfaces respectively.
5. The connector according to claim 1 , wherein a pair of the contact surfaces are supported to contact with a top surface and a bottom surface of an opening, and the pair of the protruding portions are supposed elastically at a top surface and a bottom surface of an insertion portion inserted into the opening.
6. The connector according to claim 1 further comprising; a male connector having a plurality of male contacts and the insertion portion; and a female connector having a plurality of female contacts and the opening, wherein each of the plurality of the male contacts is contacted with each of the plurality of the female contacts when the insertion portion is inserted into the opening.
7. The connector according to claim 1 , wherein the male connector and the female connector are secured to a substrate through the male contacts and the female contacts.
8. The connector according claim 1 , wherein the inclination angle of the first inclined surface is equal to the inclination of the second inclined surface.
9. The connector according to claim 2 , wherein the first inclined surface and the second inclined surface are spherical shaped.
10. The connector according to claim 3 , wherein a pair of the female contacts are disposed oppositely, and the pair of the male contacts are disposed such that the pair of the protruding portions are contacted with the pair of the contact surfaces respectively.
11. The connector according to claim 4 , wherein a pair of the contact surfaces are supported to contact with a top surface and a bottom surface of an opening, and the pair of the protruding portions are supposed elastically at a top surface and a bottom surface of an insertion portion inserted into the opening.
12. The connector according to claim 5 , further comprising; a male connector having a plurality of male contacts and the insertion portion; and a female connector having a plurality of female contacts and the opening, wherein each of the plurality of the male contacts is contacted with each of the plurality of the female contacts when the insertion portion is inserted into the opening.
13. The connector according to claim 6 , wherein the male connector and the female connector are secured to a substrate through the male contacts and the female contacts.
14. The connector of claim 1 , wherein the first and second inclined surfaces bias the protruding portion in opposed lateral directions from the contact surface.
15. The connector of claim 1 , further comprising a mitigated surface for mitigating a step between the first inclined surface and the second inclined surface such that that the protruding portion disposes smoothly with reduced friction.
