Abstract:
1. A wireless battery snap for connection used in an electrical device to connect a battery, with a front side of the battery having two parallel contact ends for contacting a cylindrical socket and a cylindrical plug on a same plane with opposite polarity, the wireless battery snap comprising: an insulating support made of insulating material with two through holes thereon, a longitudinal central distance of the two holes corresponding to a distance of two electrodes on one end of the battery, a protruded post and a through slot being provided on a plane of one end of the support and near the first through hole for receiving a contact plate while two reversed protruded posts and an open annular wall are provided near the second through hole for receiving a conductive spring, a cylindrical guide post being provided near the second through hole for receiving a guided hole of an insulating cover, an annular outer wall surrounding an outside of the insulating support for receiving the insulating cover, while on a plane of the other end of the support an inner annular wall surrounds the cylindrical socket; a width of the inner annular wall, along a horizontal axis of the insulating support being shorter than that of the cylindrical socket and plug, while a width of the annular outer wall is shorter than that of the protruding contact plate after assembling; the contact plate made of a conductive material, one end of the contact plate being inserted into the first through hole from the through slot of the insulating support with the other end disposed on the protruded post to form a contact plane, on another side of the insulating support an end of a first of two inserted conductive eyelets is fastened to the contact plate, the insulating support and the cylindrical socket and plug together; a threaded hole being formed at one end of the conductive spring, the center of the spring being located between the center of the insulating support and the two through holes, while the threaded hole is disposed on the second through hole of the insulating support, by means of inserting the conductive eyelets, disposing the cylindrical socket and cylindrical plug onto one side of the insulating support, the other end of the conductive eyelets being formed to fasten the conductive spring, insulating support and the cylindrical socket and plug together; at least one cylindrical plug being connected to a button of an electrode of the battery by means of the first conductive eyelet fastened on the insulating support, the cylindrical plug being formed of a cylinder member outwardly extending from a base with the first through hole in the middle of the cylindrical plug as the first inserted conductive eyelet; at least one cylindrical socket being connected to a button of another electrode of the battery by means of the second conductive eyelet fastened together with the second through hole in the middle of the cylindrical socket as the second inserted conductive eyelet; an insulating cover made of insulating material with a central hole in the middle and a guide post and a guide hole nearby, the guide hole being secured to the guide post in the insulating support; after assembling, an outer perimeter of the insulating cover completely surrounding the annular outer wall; a layer of double-face glue paper being applied to one side of an insulating piece and the insulating piece being applied to the conductive spring and the top of the first conductive eyelet in the contact plate.
