Abstract

In a fixation structure for fixing a lamp on a printed circuit board (PCB), a connection end of the lamp is received within a connection hole of the PCB and a reed having approximately cone shape is disposed between the lamp and the PCB. When the connection end of the lamp is continuously inserted into the connection hole of the PCB, a contact area between the connection end and the connection hole is increased, thereby effectively enhancing a contact-and-on performance of the lamp and the PCB.

Claims

1. A fixation structure for fixing a lamp on a printed circuit board (PCB), characterized in that:

the lamp has a connection end having a reed sleeved thereon and the PCB has a connection hole formed thereon, wherein the connection end of the reed is inserted into the connection hole of the PCB.

2. A fixation structure for fixing a lamp on a printed circuit board (PCB), characterized in that:

the lamp has a connection end thereon and the PCB has a connection hole formed thereon for receiving the connection end of the lamp and having a reed sleeved thereinto, the reed having a stop portion extending therefrom, the stop portion urging an external portion of the connection hole of the PCB, wherein the connection end of the lamp is inserted into the connection hole having the reed of the PCB.
