Abstract:
1. A zipper switch lampholder, comprising: a housing with an open top and an open bottom, and a connecting portion disposed at a top edge of the housing; an operating member, having a switch mechanism installed therein; a cylindrical shell, screwed and coupled to a bottom of the operating member and jointly contained in a housing, and a cylindrical shell bottom having an open bottom and a vertical wall which is a threaded casing provided for screwing and connecting a connector of a light emitting element, and a plate being installed separately on both sides of a vast majority of the open top, and each plate having a penetrating hole formed thereon; a trumpet base, having a connecting hole, fixed to an operating member and protruded towards the outside; a zipper, coupled into the operating member, and drooped outwardly from the trumpet base; and a cap, having an open bottom, a connecting portion formed at a bottom edge of the cap and coupled to the connecting portion at the top of the housing, a slot formed downwardly on a side of a periphery for passing the trumpet base out of the slot, and a through hole formed at the top for passing a power line and electrically coupling the operating member for an electric connection; characterized in that the operating member comprises: an upper cover, having a plurality of plug wire holes, a plurality of connecting holes and a plurality of hooks disposed at the top of the upper cover, and a middle containing groove, a positioning cavity and a plurality of plate slots interconnected to the plug wire holes at the bottom of an upper cover, wherein a connecting hole is provided for precisely aligning the connecting hole of the trumpet base, and a connecting element is passed for a connection, such that the trumpet base is fixed to and protruded outwardly from the upper cover, and the plug wire holes are provided for plugging a plurality of bare ends of the power line respectively, and hooks disposed near the plug wire holes are provided for connecting the power line; a lever, having a main body and a plurality of turned blocks with a slope and formed on slopes at the periphery of the top of the main body, an axial column vertically erected from a center of the main body, a containing groove formed at a bottom of the main body and penetrated upwardly to a top of the main body and a transverse groove penetrated transversally; an axial column, disposed at a position corresponding to a middle containing groove of the upper cover; a turning disk, with a dial block formed on a side, and a passing hole formed at the middle, for sheathing on the axial column of the lever, and a clamp groove formed on the other side for passing an inner end of the zipper through the trumpet base to achieve a clamping effect; a torque elastic element, together with a passing hole of the turning disk being jointly sheathed on the axial column of the lever, and then an end of the axial column being inserted and installed into the middle containing groove of the upper cover, and an end of the torque elastic element abutting the turning disk, and the other end abutting a positioning cavity of the upper cover for a positioning effect; an elastic element, contained in the containing groove of the lever; a rotating conductive rod, being substantially a column shape, such that the rotating conductive rod compresses the elastic element to retract into the containing groove to accommodate the rotating conductive rod into the transverse groove and rotated with the lever; the main body, having a plurality of long grooves formed at positions corresponding to the plate slots and the plug wire holes of the upper cover, and a connecting hole being formed at a position proximate to the bottom of the long grooves; the connecting hole and the plurality of fixing holes being formed at the periphery of the main body; after the rotating conductive rod compresses the elastic element to retract into the containing groove of the lever, and the rotating conductive rod is received into the transverse groove of the lever, the bottom of the lever together with the rotating conductive rod are jointly inserted into the middle space inside the main body; the main body includes a plurality of slopes formed around the middle space; the main body is covered by the upper cover, such that another connecting hole of the upper cover is aligned with one of the fixing holes and a connecting element is provided for the fixation; a plurality of clamp plates, being contained in the long groove, and the top end being bent and abutted into a plate slot of the upper cover for plugging the bare end of the power line into the plug wire hole, and the bottom end being bent in an opposite direction, and having a penetrating hole attached onto a connecting hole, and then a plurality of connecting elements being passed for the connection; a first conductive plate, being an oblique plate, and having a penetrating hole formed on a side, so that the top of the main body is attached onto the connecting hole, and then a connecting element being passed for the connection, and the position of the oblique plate being aligned towards the center of the main body and abutted against one of the slopes with an inclination; a second conductive plate, being an oblique plate, having a penetrating hole formed on a side, and clamped between the penetrating hole of one of the clamp plates and the connecting hole, and the connecting element being passed for the connection, such that the clamp plate and the second conductive plate are always electrically conducted, and the oblique portion of the second conductive plate is tilted towards the center of the main body and abutted against a slope obliquely; and a third conductive plate, being a double-bent plate, and having a penetrating hole, and a connecting hole attached onto the bottom of the main body to align precisely with the penetrating hole of the first conductive plate with the connecting hole in between, and then the connecting element being passed for a fixed connection, so that the third conductive plate and the first conductive plate are always electrically conducted; when the top of the cylindrical shell is attached onto the bottom of the main body, the penetrating hole formed at the top of the cylindrical shell is aligned precisely with a connecting hole and a fixing hole, and a penetrating hole is passed through the connecting element of the penetrating hole of one of the clamp plates for a fixed connection, such that the cylindrical shell and the clamp plate are always electrically conducted with each other; and after another penetrating hole is aligned precisely with the fixing hole, a connecting element is passed for a secured connection, so as to complete assembling the cylindrical shell with the main body; and a bent protruding position of the third conductive plate remains in the open space at the top of the cylindrical shell and is electrically disconnected with the cylindrical shell; such that when used, the zipper is pulled to drive the turning disk to rotate, and the dial block on the turning disk pushes a turned block to rotate and links the lever to rotate the rotating conductive rod synchronously, and an electric conduction between the rotating conductive rod and the first conductive plate and the second conductive plate is changed sequentially, so that the light emitting element is switched ON and OFF accordingly.
