Abstract
A cylindrical terminal rivet integrally made of metal comprises a base plate, a cylinder, and an elongated plate. The base plate provides a central hole and the cylinder with a closed upper end extends upright from the base plate and communicates with the central hole. The elongated plate extends outward from a lateral side of the base plate and provide at least a wing piece at two opposite edges thereof respectively. The cylinder is arranged to pass through a work piece and pressed to form a pancake like solid body so as to urge the work piece tightly and to block the central hole. Furthermore, a battery snap can be composed of two cylindrical terminal rivets, an insulation piece, a male engaging post, a female engaging post and a covering band.
Claims5
A cylindrical terminal rivet integrally made of metal, comprising:
- a base plate with a lateral side, providing a central hole;
- a cylinder, extending upright from the base plate, communicating with the central hole, and providing a closed upper end;
- and
- an elongated plate with two opposite edges, extending outward from the lateral side, providing at least a wing piece at said two opposite edges respectively;
- whereby, the cylinder is arranged to pass through a work piece and pressed to form a pancake like solid body so as to urge the work piece tightly and to block the central hole.
A battery snap, comprising
- two cylindrical terminal rivets, being integrally made of metal, each of the cylindrical terminal rivet further comprising a base plate with a lateral side providing a first central hole, a cylinder with a closed upper end extending upright from the base plate and communicating with the first central hole, and an elongated plate with two opposite edges extending outward from the lateral side and providing at least a wing piece at said two opposite edges respectively;
- an insulation piece with a plate shape, providing two pole holes, a distance between said two pole holes corresponding to a distance between two poles of a battery;
- a male engaging post, being integrally made of a conductive metal, a lower edge thereof having a flange and a cylindrical post extending upward from the lower edge, a lower ring with a second central hole therein being pierced by the cylinder, the cylinder being pressed to form a shape of pancake urging the flange tightly and blocking the second central hole, and the cylindrical post engaging with a female snap part;
- a female engaging post, being integrally made of a conductive metal, a lower part thereof extending downward an inward bottom with a third central hole being pierced by another one of the cylinders, the another cylinder being pressed to form a pancake like solid body so as to urge the bottom and block the third central hole, the upper part thereof being inward folded inversely to form a plurality of petal parts for engaging with a male snap part of the battery.
