Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and 2, a housing 1 of a wall-in control device according to a first embodiment of the present invention is shown, and the housing 1 is suitable for most wall-in control devices with a housing, such as a dimmer switch. The housing 1 has a receiving space therein to receive electronic components of the in-wall control device, and the in-wall control device can be cooled through the housing 1.
The case 1 includes an upper case 10, a lower case 20, and a heat dissipation plate 30, which are fitted to each other. The heat dissipation plate 30 wraps the lower case 20 to conduct heat inside the case 1 to the outside, thereby dissipating heat of the heat generating device inside the case 1. When the housing 1 is assembled, the heat dissipation plate 30 and the lower housing 20 are first fixed, the upper housing 10 is then fixed to the lower housing 20 from top to bottom, the upper housing and the lower housing form a clamping state with the heat dissipation plate 30 after being fixed, and the heat dissipation plate 30 is fixed by the clamping action of the upper housing 10 and the lower housing 20.
The heat dissipation plate 30 includes a heat dissipation portion 31 and fixing plates 32 bent and extended outward from both ends of the heat dissipation portion 31. The heat dissipation plate 30 is made of metal, preferably aluminum plate, and has light weight and good heat dissipation effect. In an embodiment, the heat dissipation plate 30 may be formed by a metal plate through a stamping process to form the heat dissipation portion 31 and the fixing plate 32.
The fixing plate 32 is used for fixing the wall-in control device, the fixing plate 32 is provided with a mounting hole 321, and the fixing plate 32 can be fixed on a wall or other equipment through a fixing piece penetrating through the mounting hole 321, so that the heat dissipation plate 30 not only has the function of dissipating heat for the wall-in control device, but also can be used for mounting the wall-in control device.
The heat dissipating part 31 is substantially U-shaped, and wraps both sides and the bottom of the lower case 20. The heat sink 31 is axially fixed to the lower case 20 by a first fixing structure to restrict the heat sink 30 from axially separating from the housing 1. The fixing plate 32 is fixed to the upper case 10 in the radial direction by a second fixing structure, and restricts the heat dissipation plate 30 from moving away from the housing 1 in the radial direction.

Further, the first groove 21 is disposed at the opening of the lower case 20 and is communicated with the opening of the lower case 20. With this design, after the heat dissipation plate 30 is assembled with the upper and lower cases, the upper case 10 and the lower case 20 clamp the first protrusions, thereby firmly fixing the heat dissipation plate 30 to the lower case 20.
It is understood that in other embodiments of the present invention, the first groove 21 can be disposed at an intermediate position or a bottom position of the sidewall of the accommodating groove 22, and both of the two manners can achieve the axial fixation of the heat dissipation plate 30.
The second fixing mechanism includes a pair of fingers 11 extending outwardly from two sides of the upper housing 10, and a second groove 322 formed in the fixing plate 32, wherein the fingers 11 and the second groove 322 are fastened to each other. When the upper case 10 is fixed to the lower case 20 from top to bottom, the clamping fingers 11 of the upper case 10 are engaged with the second grooves 322 of the fixing plate 32 to achieve radial fixing of the heat dissipation plate 30, so that the heat dissipation plate 30 is fixed in both axial and radial directions, and the heat dissipation plate is clamped and fixed by the upper case 10 and the lower case 20.
Further, the clamping fingers 11 extend horizontally outward along the upper surface of the upper case 10, and after the heat dissipation plate 30 is mounted to the upper case 10, the upper surface of the fixing plate 32 is located on the same plane as the upper surface of the upper case 10. That is, the heat dissipation portion 31 of the heat dissipation plate 30 extends upward to the top of the upper case 10 in addition to wrapping the lower case 20 to wrap the side of the upper case 10, thereby increasing the contact area between the heat dissipation plate and the housing 1 and improving the heat dissipation effect.
It can be understood that, for the sake of the outer appearance and convenience of installation, an accommodating groove is also formed at a contact portion between the side portion of the upper case 10 and the heat dissipation portion 31 to accommodate the heat dissipation portion 31 at a corresponding portion, and a depth of the accommodating groove of the upper case 10 is equivalent to a thickness of the heat dissipation portion 31. Therefore, when the heat dissipation plate 30 is fixed to the upper and lower cases as a whole, both side portions and the top portion of the case 1 are flat.
When the housing in this embodiment is mounted, the first connecting portion 311 of the heat dissipation plate 30 is aligned with the receiving groove 22 at the bottom of the lower housing 20 and wraps the bottom of the lower housing 20, the two second connecting portions 312 are retracted toward the receiving grooves 22 at the two sides of the lower housing 20, and after the heat dissipation plate 30 and the lower housing 20 are mounted in place, the first protrusion 33 is engaged with the first groove 21; then, the upper case 10 is fixed to the lower case 20 from top to bottom, and after the upper case 10 is mounted in place, the clamping fingers of the upper case 10 are engaged with the second grooves 322 of the fixing plate 32, and then the upper case 10 and the lower case 20 are fixed by screws, so that the heat dissipation plate 30 is fixed by the clamping action of the upper and lower cases.
