Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a lamp, such as a lamp mounted on a Christmas tree or the like, which blinks while emitting light of various colors. The lamp of the present invention has a protective pedestal structure that flashes and emits light. It has features that it is hard to fall off and falls, has a function of preventing electric leakage, and is easy to assemble.

[0002]

[Prior art]

 Conventional lamps, such as those mounted on Christmas trees, come in a variety of designs. For many products, the base is directly connected to the upper part and the lamp is fitted into the upper part to save assembly time and cost.

[0003]

[Problems to be solved by the invention]

 The structure often used in conventional Christmas lamps is low in cost and easy to assemble, but it is easy to fall off, and the power cord and base of the two metal terminals are also pulled by external forces. There is a disadvantage that it is easily loosened.

[0004] The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a lamp which is hardly dropped from a power cord and does not move or tilt from a base portion. It is.

[0005]

[Means for Solving the Problems]

 The lamp of the present invention comprises a base, an intermediate part, an upper part, two metal terminals, and a power cord connected to the metal terminals. The upper part is hollow and has two symmetrical protrusions and shoulders. Below the shoulder is a flat, opposed square trough with projections inserted and fixed into the inserts on both sides of the middle part and the inserts on both sides of the upper part. The shoulder is designed to hit the bottom of the cylindrical part of the middle part. The square trough corresponds to the middle two flat parts. The middle part is a cylindrical part at the top and two flat parts at the bottom. Between the two flat parts, there is a center barb, so that the fitting part in the center of the cylindrical part is inserted and fixed from the insertion groove at the bottom of the upper part. At the left and right ends of the fitting, there are fixing notches to fix the stepped metal terminals. In the center, a straight tank is formed on both sides of the intermediate part so that the power cord can be inserted. There are teeth on both sides of the center barb to secure the two power cords.

The lower part of the cavity of the upper part has a triangular part between the two holes, the bottom outer wall of the hole has an insertion groove, and the inner parts of the insertion parts on both sides of the upper part. There is a bath, and the protrusion on the bottom of the Christmas lamp fits in and is fixed.

[0007]

[Embodiment of the invention]

 Please refer to FIG. FIG. 2 is a three-dimensional exploded view of the Christmas lamp according to the embodiment of the present invention. The Christmas lamp according to this embodiment includes a base 10, an intermediate part 20 that fits in the base 10, an upper part 30 fixed to the intermediate part 20, an upper part 30 located at an upper end of the base 10, and two intermediate left and right parts. It comprises a metal terminal 40, a power cord 50 connected to the metal terminal 40, and a lamp 60 inserted on the upper part 30.

The aforementioned base 10 has a hollow portion 11, on each side of which there are two symmetrical projections 12 and a shoulder portion 13. The shoulder 13 is below the projection 12. Below the shoulder portion 13 are two flat opposing rectangular basins 14. A cylindrical part 21 is provided on the upper part of the intermediate part 20, and a flat part 22 extends vertically in the lower part. The cylindrical portion 21 has a fitting portion 24, and fixing notches 25 are provided at the left and right ends of the fitting portion so that a metal terminal 40 having a stepped portion 41 can be firmly fixed.

In addition, between the two flat portions 22 of the intermediate part 20, a center bar 23 is formed integrally (see FIG. 4). There are teeth 27 on both sides of the center barb 23 so that the two power cords 50 are firmly fixed. (See FIG. 5.) Further, the projections 12 on the upper end of the hollow portion 11 of the base 10 are inserted into the insertion portions 28 on both sides of the cylindrical portion of the intermediate part 20 and the insertion portions 32 on both sides of the upper part 30. And fix it. Then, the shoulder portion 13 of the base is blocked by the bottom of the cylindrical portion 21 of the intermediate part, and the intermediate part 20 fits into the base 10 and is fixed. When the square trough 14 of the base and the two flat parts 22 of the intermediate part are combined, the intermediate part 20 does not move or tilt in the base 10.

The metal terminal 40 is formed by molding a thin piece of metal having excellent conductivity, and has a narrow upper portion and a wider lower portion when viewed from the front. The edges on both sides of the upper half of the metal terminal 40 have a step-like portion 41 formed in the shape of a sawtooth, and have a symmetrical leaf-like shape as a whole. On the left and right sides of the lower half of the metal terminal 40, there are two laterally U-shaped cuts, and wing pieces are formed on the upper and lower sides of the cut. The upper wing has a smaller width than the lower wing. However, the length of the upper wing is greater than that of the lower wing. The bottom of the lower wing is slightly arcuate. Then, of the two wing pieces, the lower wing piece is bent inward from the outside of the power cord 50 so as to hold the power cord 50 and joined to the outside of the covering material of the power cord 50. Further, the upper wing piece is bent inward from the outside of the metal wire of the power cord 50 exposed to the front of the covering material of the power cord 50 so as to hold the metal wire, and is bent inward. Connect to wire. Thus, the metal terminal 40 can be firmly fixed to the power cord 50 (see FIG. 1).

When the lamp 60 is inserted into the hollow storage portion 31 of the upper part 30, the lamp cord 61 comes out of two holes 33 at the lower end of the hollow storage portion. The lamp cord which has come out further has a conductive function by being bent toward the outer wall and coming into contact with the metal terminal 40 (see FIG. 5). In addition, the lamp cord 61 comes out of the hole 33 and the triangular portion 35 between the two holes 33 is such that the lamp cord 61 goes out and bends outward. After that, the upper part has a groove 34 in the outer wall at the bottom of the hole 33 so that the upper part can be easily contacted with the metal terminal 40 after being bent. At the lower end of the upper part 30, there is an insertion part 36, and the insertion part 35 is fitted and fixed to the fitting part 24 of the intermediate part 20. Further, a recessed portion 37 is provided inside the groove 32 on both sides of the upper part 30 so that the projection 62 on the bottom of the lamp 60 can be fitted and fixed. Therefore, the lamp 60 is fixed upright to the upper part 30.
