Abstract
Description
Technical Field
[0001] The utility model relates to an outdoor street lamp controller with good waterproof performance. Background Art
[0002] With the popularization and promotion of the concept of smart city, smart street lights have achieved unprecedented development. Street light controllers are controllers that control the switch of lamps by sensing changes in light sources, and they play an important role in urban street lights. Since street light controllers are used outdoors, they are easily eroded by rainwater, so their sealing is particularly important. In actual use, it is found that rainwater easily enters from two places of existing street light controllers: one is the gap between the controller base and the controller cover, and the other is the gap between the controller contact and the controller base. In view of this, the existing outdoor street light controllers are improved and optimized. Utility Model Content

[0005] The upper surface of the controller base is provided with a base recess, a base inner rib, a first positioning groove and a base docking convex edge docking with the cover body docking groove in sequence from the inside to the outside; a base snap-in corresponding to the cover body block is provided on the outer wall of the base docking convex edge; a contact mounting boss for inserting the controller contact is provided in the middle of the base recess, a second gluing groove is provided in the contact mounting boss, and sealant is provided in both the gluing groove and the second gluing groove.
[0006] It also includes a first sealing gasket and a contact sealing gasket, the first sealing gasket is placed in the first positioning groove, the inner wall of the second glue groove is provided with a second positioning groove, and the contact sealing gasket is placed in the second positioning groove.
[0007] The controller contact is provided with a contact limiting recess, and the contact sealing pad is provided with a sealing pad inner snap-in for sleeved on the contact limiting recess.
[0008] The drainage hole is arranged obliquely and is higher inside and lower outside.
[0009] The inner rib of the base is higher than the butt convex edge of the base.
[0010] The sealant is silicone sealant.
[0011] The utility model has the advantages of an outdoor street lamp controller with good waterproof performance. The gap between the controller cover and the controller base and the gap between the controller contact and the controller base are both double waterproof sealed by sealant and sealing gasket. A drainage hole is provided on the controller cover so that when gaps appear in the sealant, moisture can be quickly and timely discharged, thereby effectively improving the overall sealing and waterproof performance of the street lamp controller.
