Definitions

• the present invention relates to a lamp holder, in particular to a lamp holder for a decorative lamp.
• the traditional decorative lamp is a plug-in type. As shown in FIG. 6, it basically includes a light bulb 40, a base 210, a lamp holder 220 and two wires 50. The bulb 40 is inserted into the base 210 and is inserted into the socket body 220 together, so that the terminals of the bulb 40 are in contact with the wires 50 inserted in the socket body 220, thereby forming a complete decorative lamp.
• the light bulb is loosely inserted into the base, and then inserted into the socket body, so after assembly, the bulb will occur in the socket assembly composed of the base and the socket body. Rotate, so it is easy to cause poor contact between the terminal of the bulb and the wire inserted in the lamp holder. Poor electrical contact can easily cause the lamp to dim and reduce the life of the lamp.
• an object of the present invention is to provide a lamp socket assembly capable of preventing the lamp from rotating or loosening, and improving contact performance and service life.
• Another object of the present invention is to provide a lamp socket assembly capable of preventing the lamp from rotating and preventing the electric wire from being loosened.
• the present invention provides such a lamp holder assembly, which includes a base and a lamp holder body.
• the base includes a hollow cylindrical part for receiving a light bulb and a rectangular parallelepiped extension part.
• the lamp holder body includes a corresponding A cylindrical cavity part and a rectangular cavity part are characterized in that the opposite side of the cylindrical part of the base is cut to be substantially flush with the rectangular parallelepiped extension part to form two mouths, and the cylindrical cavity part of the lamp holder body is correspondingly
• the rectangular parallelepiped cavity portion of the lamp holder body basically has two longitudinally extending ridges opposite to each other on the extension line of the rib, thereby defining two incompletely separated wire receiving areas.
• the aforementioned lampholder assembly further includes a wedge member shaped to be inserted between the opposite convex strips of the lampholder body to further separate the two wire receiving areas.
• the lamp holder assembly of the present invention has the following advantages.
• the cylindrical cavity portion of the lamp holder body has two opposite convex ribs extending longitudinally corresponding to the opening of the base. Therefore, when the light bulb is inserted into the base, its outer periphery is at two opposite sides of the base. The mouth is exposed and engages with two opposite convex ribs of the lamp holder body. The convex ribs tightly squeeze the bulb, thereby effectively preventing the bulb from rotating or loosening in the lamp holder assembly, and ensuring good bulb terminals and wires. Contact increases the life of the bulb.
• the cuboid cavity portion of the lampholder body basically has two opposite convex strips extending longitudinally on the extension line of the rib, two incompletely separated wire receiving areas are defined, which effectively blocks the bare parts of the wires. Make them have sufficient electrical clearance to ensure electrical safety without affecting the assembly, making assembly as easy as unobstructed ridges.
• the wedging member can be wedged and installed between the two opposite convex strips after the electric wire and the bulb are successfully assembled into the lamp holder assembly, thereby further Separating the two wires and preventing them from loosening ensures that the wires are held in place without accidentally coming out of the lampholder assembly.
• the structure is relatively simple, the manufacturing process requirements are relatively low, and it is easy to assemble, which can reduce manufacturing costs.
• FIG. 1 is a longitudinal sectional view of a lamp holder assembly according to a preferred embodiment of the present invention, the lamp holder assembly has been equipped with a bulb and an electric wire;
• FIG. 2 is a cross-sectional view of the lamp holder assembly taken along a plane perpendicular to the cross-section of FIG. 1;
• FIG. 3 is a perspective view of a base of the lamp holder assembly
• FIG. 4 is a partially cutaway perspective view of a lampholder body of the lampholder assembly
• FIG. 5 is a perspective view of a wedge of the lamp socket assembly.
• Fig. 6 is a partially cutaway perspective view of a conventional decorative lamp.
• Fig. 3 and Fig. 4 respectively show the base and the lampholder body constituting the lampholder assembly of the present invention.
• the base 10 is roughly composed of two parts, that is, a hollow cylindrical portion 11 and a rectangular parallelepiped extending portion 12, which are integrated with each other.
• the rectangular parallelepiped extension portion 12 has a through hole 13 which communicates with the hollow cavity of the cylindrical portion 11 for inserting a light bulb (not shown).
• the opposite sides of the hollow cylindrical portion 1 1 are cut substantially flush with the rectangular parallelepiped extension 12 to form two large-area openings 14 facing each other.
• the width of the opening 14 is substantially the same as the width of the rectangular parallelepiped extension 12.
• the upper end of the cylindrical portion 1 1 is provided with a flange 15 for cooperating with the upper edge of the base 20 when the base 10 is inserted into the base 20.
• the lamp holder body 20 is also composed of two parts, that is, a cylindrical cavity portion 21 and a rectangular cavity portion 22, which are integrated with each other.
• the cylindrical cavity portion 21 is made to accommodate the base 10
• the hollow cylindrical portion 11 has two longitudinally extending ribs 23 formed on the inner wall corresponding to the opening of the base 10 for engaging with the outer wall of a light bulb inserted into the base 10, between the two ribs 23
• the relative spacing is slightly smaller than the diameter of the bulb to be inserted, so that the rib 23 can squeeze the bulb tightly to prevent the bulb from turning or loosening.
• the rectangular parallelepiped cavity portion 22 forms a generally rectangular parallelepiped cavity for receiving the rectangular parallelepiped extension portion 12 of the base 10.
• Two ridges 24 opposite to each other are formed on the wall of the rectangular parallelepiped cavity approximately on the extension line of the rib 23, and the two ridges substantially divide the cuboid cavity into two incompletely separated wire receiving areas. Each is used to accommodate two inserted wires.
• FIGS. 1 and 2 are cross-sectional views of an assembled decorative lamp taken along two mutually perpendicular sections.
• the light bulb 40 is inserted into the base 10, and the base 10 is inserted into the lamp holder body 20.
• the two opposite longitudinally extending ribs 23 of the lamp holder body 20 are engaged with the periphery of the bulb 40, thereby preventing the bulb from rotating or loosening.
• Two electric wires 50 are respectively inserted in the two electric wire accommodating areas of the lamp holder body 20, and they are connected to a power source or connected in series with other decorative lamps. Most of the electric wire 50 is wrapped by the insulating sleeve 52, and only the lead portion 51 is exposed at the head.
• the lead portion 51 is in contact with the terminal 41 of the bulb 40 through a contact piece 53 fixed to the end portion thereof.
• a T-shaped wedge member 30 is wedged from the lower part of the lamp holder body 20 to the opposite convex strip 24, thereby completely separating the two electric wires 50 and keeping them in place.
• Fig. 5 shows a perspective view of the T-shaped wedge member 30.
• the wedge member can also be made into any other suitable shape.
