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. The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The present embodiment provides a small-sized driver 100 and a light fixture, which have the advantages of improving the space utilization and reducing the occupied ceiling space, and will be described in detail below with reference to the accompanying drawings.

In one embodiment, referring to fig. 1 to 3, a small-volume driver 100 includes an upper housing 110, a lower housing 120, and a plurality of anti-pulling elements 121. The upper housing 110 and the lower housing 120 are butted to form a cavity. The anti-pulling member 121 is disposed in the cavity, the anti-pulling member 121 includes a first end 1211 and a second end 1212, the first end 1211 is connected to the lower housing 120, the second end 1212 is a free end, the anti-pulling member 121 is disposed at an interval, a gap 122 is formed between adjacent anti-pulling members 121, and the gap 122 is used for accommodating the cable 200.

The small-size driver 100 that this embodiment provided is equipped with in and prevents drawing 121, and in the clearance 122 between a plurality of anti-drawing 121 was directly worn to locate by cable 200, need not additionally set up the cable at the tip of driver 100 and prevent drawing the structure, be favorable to reducing the volume of driver 100, and then reduce driver 100 and to the occupation in smallpox space, also be favorable to reducing material cost simultaneously, and cable 200 assembles simply swiftly.

In one embodiment, referring to fig. 1 to 3, a pushing member (not shown) is disposed in the upper housing 110, and the pushing member is disposed corresponding to the gap 122. Thus, when assembling the small-sized driver 100, the cable 200 is first wound in the gap 122 between the tension preventing members 121, and then the upper case 110 is assembled to the lower case 120. In the process of assembling the upper housing 110 to the lower housing 120, the pushing member is inserted into the gap 122 to tightly press the cable 200 into the gap 122, thereby preventing the cable 200 from moving or falling off, and thus achieving the pull-proof effect of the cable 200. In order to prevent the pushing member from damaging the cable 200, a silicone washer or a foam pad may be provided at an end of the pushing member facing the gap 122 to avoid abrasion of the cable 200.

In one embodiment, referring to fig. 1 to 3, the anti-pulling member 121 is a trapezoidal flat plate, the second end 1212 is disposed toward the upper housing 110, and the first end 1211 is larger than the second end 1212. For example, three anti-pulling members 121 are disposed at an end of the lower housing 120, and the three anti-pulling members 121 are arranged in a triangle. Since the first ends 1211 of the anti-pull members 121 are larger in size than the second ends 1212, the gap 122 formed between the first ends 1211 of adjacent anti-pull members 121 is the largest and the gap 122 formed between the second ends 1212 of adjacent anti-pull members 121 is the smallest. Therefore, when the cable 200 is wound around the tension preventing member 121, the more the cable 200 moves toward the second end 1212, the more the cable 200 is tightly caught. When the upper housing 110 and the lower housing 120 are assembled together, the pushing member of the upper housing 110 further clamps the cable 200 in the gap 122, so as to achieve the pull-proof effect of the cable 200.

Further, the upper case 110 further includes a third side surface 114 and a fourth side surface, the third side surface 114 and the fourth side surface are respectively connected to two sides of the top surface 111 along the width direction thereof, and the third side surface 114 and the fourth side surface are a third plane. The first side 112, the third side 114, the second side 113 and the fourth side are sequentially connected in a surrounding manner. The junction of the top surface 111 and the first side surface 112, and the junction of the top surface 111 and the second side surface 113 are respectively provided with an arc transition angle 115. The provision of the arc-shaped transition angle 115 effectively prevents an installer from being scratched when installing the small-sized driver 100, which is advantageous for protecting the safety of the installer. The upper housing 110 of the small-volume actuator 100 provided by this embodiment is designed to be an arc-shaped surface, a spherical surface, and an outline in which planes meet, compared with the conventional actuator in a cube shape, the small-volume actuator 100 provided by this embodiment is beneficial to reducing the volume of the actuator 100 and reducing the occupation of the ceiling space while ensuring the effective use space inside the small-volume actuator 100. And the curved surface design also facilitates the placement of the small-volume driver 100 from the circular hole 310 of the ceiling 300 into the space between the ceiling 300 and the ceiling top wall 400.
