Contact and method for making same
A method for making a contact begins by providing a sheet of material. A portion of the sheet is deep drawn to form a cavity having at least one side wall, the cavity extending away from a rim formed by a non-drawn portion of the sheet. At least one spring member is defined from the at least one side wall and is bent such that at least a portion of the at least one spring member extends beyond the rim.
1. A method for making an electrical contact, comprising the steps of:
providing a sheet of material;
deep drawing a portion of the sheet of material to form a hollow tubular body having a first end, a second end and at least one linear side wall;
forming a rim by a non-drawn portion of the sheet of material on either the first end or the second end, the rim extends perpendicularly from the at least one linear side wall, having a thickness which is less than the length of the hollow tubular body;
defining at least one spring member from the at least one linear side wall; and
bending the at least one spring member such that at least a portion of the at least one spring member extends beyond the end on which the rim is provided.
2. The method of claim 1 , further comprising shaping the portion of the at least one spring member to form a contact surface.
3. The method of claim 1 , further comprising shaping the portion of the at least one spring member to form an arched contact surface.
4. The method of claim 1 , further comprising shaping the portion of the at least one spring member to form an angular contact surface.
5. The method of claim 1 , further comprising the hollow tubular body having a bottom and removing at least a portion of the bottom of the hollow tubular body.
6. A method for making an electrical contact, comprising the steps of:
providing a sheet of material;
deep drawing a portion of the sheet of material to form a hollow cylindrical body having a first end, a second end and at least one linear side wall;
forming a rim by a non-drawn portion of the sheet of material on either the first end or the second end, the rim extends perpendicularly from the at least one linear side wall, having a thickness which is less than the length of the hollow cylindrical body;
defining at least one spring member from the at least one linear side wall; and
bending the at least one spring member such that at least a portion of the at least one spring member extends beyond the end on which the rim is provided to form a contact surface.
7. A method for making an electrical contact, comprising the steps of:
providing a sheet of material;
deep drawing a portion of the sheet of material to form a hollow tubular body having a first end, a second end and at least two linear side walls;
forming a rim by a non-drawn portion of the sheet of material on either the first end or the second end, the rim extends perpendicularly from the at least two linear side walls, having a thickness which is less than the length of the hollow tubular body;
defining at least one spring member from at least one of the at least two linear side walls; and
bending the at least one spring member such that at least a portion of the at least one spring member extends beyond the end on which the rim is provided to form a contact surface.
8. A method for making an electrical contact, comprising the steps of:
providing a sheet of material;
deep drawing a portion of the sheet to form a hollow tubular body having a first end, a second end and at least two linear side walls;
forming a rim by a non-drawn portion of the sheet of material on either the first end or the second end, the rim extends perpendicularly from the at least two linear side walls, having a thickness which is less than the length of the hollow tubular body;
defining at least two spring members, each of the at least two spring members being formed from a corresponding one of the at least one of the at least two linear side walls; and
bending each of the at least two spring members such that at least a portion of each of the at least two spring members extends beyond the end on which the rim is provided to form a contact surface.
