BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the contents of the present invention will be described in detail with reference to embodiments of the present invention, but the present invention is not limited thereto.
[0015]
[First Embodiment]

As shown in FIG. 1A, the power supply contact structure according to the present embodiment is configured such that high voltage electrodes 11 and ground electrodes 12 are alternately stacked inside a unit main body 100, and the electrode surfaces are shared by a common metal. Contact structure of an electric precipitating air purifier that is electrically connected by a power supply contact member 13 made of aluminum, comprising: a power supply contact member 13 for pressing an end 11a of each high-voltage electrode 11 while bending the same; And hook-shaped locking means 14 for locking the lock.
[0016]
In the present embodiment, an insulative power supply contact cover 15 that protects the power supply contact member 13 is provided integrally, and the power supply portion 13a of the power supply contact member 13 extends from a partially cut-out portion 15a of the power supply contact cover 15. Is exposed and power can be supplied.
[0017]
Further, a wedge portion 15b is formed at an end portion of the power supply contact cover 15 perpendicular to the longitudinal direction, and the power supply contact cover 15 integrated with the power supply contact member 13 is moved downward from the top in the stacking direction of the high voltage electrodes. When the power supply contact member 13 is inserted toward the side, the end portion 11a of the high-voltage electrode 11 is bent in the insertion direction on the back surface side of the power supply contact member 13 and the power supply contact member 13 is locked by the end locking means 14, thereby forming the side plate 101. The end 11a of the high-voltage electrode 11 is integrally pressed.
[0018]
Then, by fastening the upper portion of the power supply contact cover 15 with the screw 21, the power supply contact cover 15 integrated with the power supply contact member 13 can be attached to the unit main body 100.
[0019]
Thereby, the operation direction of the jig for laminating the high-voltage electrodes in the unit main body 100 and the operation direction of the tool for fastening the power supply contact member 13 become the same direction, and the process can be simplified.
Further, the locking between the wedge portion 15b and the hook-shaped locking member 14 ensures the locking.
[0020]
Also, by gradually narrowing the distance d between the hook-shaped locking members 14 as it goes downward, the insertion of the power supply contact cover 15 becomes easy, and the removal of the power supply contact cover 15 during disassembly becomes easy, As a result, the dismantling work becomes easy, and the work efficiency of the recycling work is improved.
That is, assuming that the distance d between the hook-shaped locking members 14 is the same, when the power supply contact cover 15 is inserted and locked, it is possible to lock by increasing the insertion force. However, on the contrary, when the power supply contact cover 15 is pulled out, each locking member located on the upper side becomes obstructive and it becomes difficult to pull it out. However, as the present invention reduces the locking interval d, it gradually becomes narrower. By doing so, this can be resolved.
[0021]
Further, the hook-shaped locking member 14 can be locked without providing the wedge portion 15b by making the entrance side wider and the exit side narrower. Even in such a case, the power supply contact cover 15 can be easily pulled out at the time of disassembly by making the power supply contact cover 15 step-shaped and lowering the step as it goes downward.
