Connector, LED unit, and method for producing connector
View Patent ↗A connector includes: one terminal having a part-connecting portion to be connected to an anode of an LED; and the other terminal having the part-connecting portion to be connected to a cathode of the LED; and a housing in which the terminals are embedded. The connector is made by insert-molding. The terminals are arranged in a cavity formed between upper and lower dies so that the part-connecting portions are arranged in the same plane with a gap. An outer shape of the cavity corresponds to an outer shape of the connector. After a projection formed on the upper die is interposed between the part-connecting portions, the cavity is filled with melted synthetic resin to mold the housing.
1. An LED unit comprising:
an LED chip;
a conductive metallic bus bar;
a housing made of insulating synthetic resin;
an LED packaging portion formed on the bus bar, having a packaging surface on which the LED chip is packaged, and a non-packaging surface opposite to the packaging surface;
a heat-radiating opening formed on the housing with which the bus bar is integrally formed; and
a heat-radiating space interposed between the non-packaging surface and the heat-radiating opening.
2. The LED unit as claimed in claim 1 ,
wherein a heat-radiating piece folded toward the non-packaging surface is coupled to the LED packaging portion, and exposed to a side of the housing.
3. The LED unit as claimed in claim 1 ,
wherein a wire-connecting portion for connecting an electric wire is formed on the bus bar, and a shock-absorbing portion for absorbing a shock generated by connecting the electric wire is formed between the wire-connecting portion and the LED packaging portion.
4. The LED unit as claimed in claim 3 ,
wherein the shock-absorbing portion is a folding portion of the bus bar of which upper side is continued to the LED packaging portion, and of which lower side is continued to the wire-connecting portion.
5. The LED unit as claimed in claim 3 ,
wherein a second heat-radiating space is formed under the wire-connecting portion.
