Abstract

(57) [Summary] [Purpose] To prevent vibration and shock during transportation of the inverter.
The purpose is to prevent the parts from being removed from the printed circuit board. [Structure] A comparatively heavy oscillation transformer, choke, etc. are held by tape as shown in the figure, and the tip of the tape is attached to the body frame.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention proposes prevention of attachment / detachment of parts from a printed circuit board against vibration, shock, etc. during transportation of the inverter.

 FIG. 1 shows an embodiment of a fluorescent lamp inverter circuit. Reference numeral 1 is an inverter, 11 is an oscillation transformer, 12 is a noise filter, 13 is an electrolytic capacitor, 14 is a bridge, 15 is a choke, 16 and 17 are transistors, and 4 is a fluorescent lamp.

 FIG. 2 is an implementation structural diagram of the inverter circuit of FIG. Reference numeral 21 is a printed circuit board, 31 and 32 are tapes of the present invention, 33 is an inverter body frame, and 34 is an inverter body cover. Other symbols are the same as in FIG.

 As shown in FIG. 2, the oscillating transformer 11 and the choke 15 are relatively large and heavy. For example, in the FLR110W × 2 inverter, if the E / E4056 iron core is used for the oscillation transformer 11, the weight of the transformer 11 will be 150 g. Due to the weight, the terminal pin of the oscillation transformer 11 is printed circuit board against shock and vibration. It becomes easy to deviate from 21.

 FIG. 3 is a side view showing a state in which the oscillation transformer 11 and the choke 15 of FIG. 2 are attached to the printed board 21. Each P is a terminal pin and S is a solder finish, and also serves to attach and fix the vibration transformer 11 and the choke 15 to the printed circuit board 21. In this case, when the oscillation transformer 11 and the choke 15 are pressed with the tapes 31 and 32 having a width of about 10 mm as shown in the figure and the tip of the tape is attached to the main body frame 33, the printed circuit board 21 receives shock and vibration during transportation. Desorption is greatly prevented. Once they are installed on the ceiling, etc., they are not particularly impacted or vibrated, and temporary reinforcement with tape is not a great burden in terms of cost and has a large economic effect.

In addition, when the electrolytic capacitor 13 and the like become large and there is a concern that the electrolytic capacitor 13 may be detached from the printed board 21, the present invention may be adopted.
