Switchless lamp holder

A switchless lamp holder, comprising:

• a main casing made of a non-conductive material, having a pair of hooks vertically configured inside a top surface, an assisting hook formed on a front edge of a bottom of the hook, a retaining edge configured on the top surface of the main casing corresponding to the front of the hook, a catching slot configured on an adjacent side of each hook, a pair of positioning blocks convexly and correspondingly configured on the top surface of the main casing closed to a peripheral edge, a downward through plug hole configured on each positioning block, an interior of the main casing hollowed downward to form a space, a pair of holding thin slots concavely configured on the wall inside the space in an interlaced and corresponding arrangement and correspondingly configured with a pair of lateral thread convex bodies, the threads of the corresponding thread convex bodies being continuous and a positioning slot formed under each plugs hole;
• a cover casing made of a non-conductive material, having a downward through connecting slot configured in a middle of a top edge, a bottom of the cover casing hollowed downward to form a space, a pair of catching bars downward and vertically configured inside the space corresponding to the two sides of the connecting slot, the bottom end of the catching bars formed with a catching hook, the catching bar and the said catching slot corresponding to each other, a pair of positioning slots concavely and corresponding configured on the bottom edge of the cover casing, the positioning slot corresponding to the said positioning block, while assembling, the space on the bottom of the cover casing aligning the top surface of the main casing to cover, enabling the positioning slot of the cover casing to align the positioning block of the main casing and meanwhile, the catching bar of the cover casing being inserted into the catching slot of the main casing, the catching hook on the bottom of the catching bar being hooked on the wall of the catching slot to enable the cover casing and the main casing to be engaged;
• a first conducting plate made of a conductive material, having a slightly tilted clamping section, wherein a middle of a front end concavely provided with a concave contact slot and a tail end bending downward to form a contact section, a middle part tilting backward to form a middle tilted plate and the two sides tilting forward to form a lateral tilted plate, a bottom end of the contact section tilting forward to form a first connecting section, wherein two sides respectively tilting downward to form a lateral tilted plate, a tail end of the first connecting section bending downward to form a second connecting section, wherein two sides respectively tilting forward to form a lateral tilted plate, a bottom edge of the second connecting section tilting backward and shrinking to further extend vertically downward to form a conducting plate having a pair of conducting flanges protruding backward, the bottom edge of the conducting plate tilting forward and further extending vertically downward to form a bottom section, the two sides of the bottom edge respectively extending to form a pressing plate, and while assembling, the first conducting plate being pushed in from the space inside the main casing along a corresponding holding thin slot on the wall, enabling the clamping section, the contact section, the first connecting section and the second connecting section of the first conducting plate to enter into the positioning slot and clamp with an internal wall, and meanwhile, the pressing plate extending from the two sides of the bottom section clamping with the two side walls of the holding thin slot, enabling the first conducting plate to be fixed, the clamping section of the first conducting plate resting inside an upper section space of the positioning slot, and meanwhile the conducting plate and the conducting flanges protruding into the space of the main casing;
• and,
• a second conducting plate made of a conductive material, having a slightly tilted clamping section, wherein a middle of a front end concavely provided with a contact slot, a tail end bending downward to form a contact section, a middle part tilting backward to form a middle tilted plate and the two sides respectively tilting forward to form a lateral tilted plate, a bottom end of the contact section tilting forward to form a first connecting section, wherein the two sides respectively tilting downward to form a lateral tilted plate, a tail end of the first connecting section bending downward to form a second connecting section, a bottom edge of the second connecting section tilting backward to form a conducting plate, wherein a surface protruding downward to form a conducting flange protruding, while assembling, the second conducting plate being pushed into from the space inside the main casing along the other corresponding holding thin slot on the wall, enabling the clamping section, the contact section, the first connecting section and the second connecting section of the second conducting plate entering into the other positioning slot and clamp with the internal wall, and meanwhile the conducting plate and the conducting flange entering into the space of the main casing.
