Lamp holding unit
View Patent ↗A lamp holding unit includes a coupling terminal and a main body. The coupling terminal includes a coupling plate extended in a direction crossing a longitudinal direction of a lamp. The coupling plate has a cutout portion to receive a lead line of the lamp so that the cutout portion of the coupling plate making contact with the lead line. The main body is coupled with the coupling terminal and guiding the lamp. Therefore, an electrical connection between the lamp holding unit and the lead line of the lamp is stabilized, so that noise or spark caused by mal-connection is prevented.
1. A lamp holding unit comprising:
a conductive base including:
a base plate including metal; and
a plurality of coupling terminals protruded from the base plate, the coupling terminals being spaced apart from each other, a cutout portion being formed through an upper portion of each of the coupling terminals, a plurality of lead lines of a lamp being received in the coupling terminals so that the lead lines are electrically connected to the conductive base;
a cover received on the conductive base, a plurality of throughholes being formed through the cover corresponding to each of the coupling terminals to guide the plurality of lead lines,
wherein a cutting slit is formed through each of the coupling terminals under the lead lines.
2. The lamp holding unit of claim 1 , wherein sides of the base plate are folded to form U-shape with respect to a longitudinal direction of the lamp, and the coupling terminals are integrally formed with the base plate.
3. The lamp holding unit of claim 2 , wherein a plurality of holes spaced apart from each other is formed through the folded side of the base plate.
4. The lamp holding unit of claim 1 , wherein an upper corner of each of the coupling terminals is chamfered.
5. The lamp holding unit of claim 1 , wherein the cover comprises:
an upper plate having an extended shape;
a first side plate bent toward a lower portion of the lamp holding unit and having the throughhole; and
a second side plate bent toward the lower portion of the lamp holding unit.
6. The lamp holding unit of claim 5 , wherein the cover comprises a synthetic resin.
7. The lamp holding unit of claim 5 , wherein a plurality of protrusions is formed on the first and second side plates corresponding to the holes of the base plate, and the protrusions are received in the holes of the base plate.
8. The lamp holding unit of claim 5 , wherein the cover further has a plurality of compressing portions that surround the chamfered corners of the coupling terminals and press the chamfered corners.
9. The lamp holding unit of claim 8 , wherein the cover further comprises a partition wall interposed between adjacent compressing portions, and the partition wall is integrally formed with the upper plate.
