Description

  The present invention relates to a socket for connecting a module substrate such as an LED for illumination.

In recent years, technological development relating to high-density arrangement of light emitting diodes (LEDs) has progressed, and the LED module substrate for illumination is being put to practical use.
An example of a socket for connecting such a high-density substrate is shown in FIG.
FIG. 5A shows a lighting LED module substrate 101 and a socket 110 mounted on a high-density board in which a plurality of light emitting diodes are arranged in a planar shape.
FIG. 5B shows a state in which the substrate 101 is fitted and the wiring wire 150 is connected, and a cross-sectional view taken along line FF is shown in FIG.
As shown in FIG. 5 (c), the contact 140 is pressed and connected to the connection part 101 a of the socket 110 and the substrate 101 by a spring force, and the wiring wire 150 to be connected to the contact terminal part 142 is soldered. It was connected with the date.
However, the strength of the terminal portion 142 of the contact 140 is relatively weak, and a large number of the terminal portions 142 are arranged at a high density at a narrow pitch, so that the terminal portion 142 may be deformed by mistake during the soldering operation. There is a high risk of shorting between terminals due to bridge connection with adjacent contact terminals, and there is a problem in soldering workability and quality.
Japanese Patent Application Laid-Open No. 2004-192877 discloses a technique for connecting an LED and a printed circuit board without soldering.
However, it is a structure in which an LED having only a pair of terminals is directly fitted into a housing-like insulator and is connected to a printed circuit board through a contact, and a module board such as an illumination LED is fitted into a socket, This is different from a structure in which a large number of connection portions provided on the substrate and wiring wires are connected at a narrow pitch, which is insufficient for connecting the substrate.
