Description

Technical Field

[0001] The utility model belongs to the technical field of drive power supplies, and particularly relates to an LED drive power supply. Background Art

[0002] An LED drive power supply is a power converter that converts a power supply into a specific voltage and current to drive LEDs to emit light. Generally, the input of an LED drive power supply includes high-voltage industrial frequency alternating current (i.e., mains power), low-voltage direct current, high-voltage direct current, low-voltage high-frequency alternating current (such as the output of an electronic transformer), etc.

[0003] Some types of drive power supplies are divided into an upper case, a lower case, and a gland. During assembly, the upper case is first installed on the lower case, and then notches are provided on both sides to facilitate wire pressing adjustment, so that the wires are exposed through the notches. Finally, the gland is installed. However, the existing gland is not designed with a positioning mechanism for the gland. During installation, the gland is only inserted corresponding to the notches. The lack of a positioning mechanism easily causes position deviation and a large error in screwing the screws. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an LED drive power supply, including:

[0005] An upper case, with notches formed at both ends, a positioning platform formed at the notches, and a positioning groove formed on the positioning platform;

[0006] A lower case, assembled to be adapted to the upper case;

[0007] A gland, with a positioning block provided inside, the gland being installed at the notch and covering the positioning platform, and being connected in a snap-fit manner through the positioning block and the positioning groove.

[0008] A further embodiment of the utility model is that a buckle is provided on the outer side of the lower case, and a clamping groove is provided on the inner wall of the upper case, and the buckle and the clamping groove are connected in a snap-fit manner.

[0009] A further embodiment of the utility model is that a stud is provided on the lower case, and a groove is provided on the gland. When the gland is arranged on the positioning platform, the groove corresponds to the stud and is connected in a screwed manner through a screw.

[0010] A further embodiment of the utility model is that a wire clamping plate is provided between the studs on the lower case.

[0011] A further embodiment of the utility model is that it further includes a circuit board, and the circuit board is arranged inside between the upper case and the lower case.

[0012] A further embodiment of the utility model is that a plurality of equally spaced heat dissipation holes are provided on both sides of the upper case.

[0013] The beneficial effects of the utility model are:

[0014] This LED driver power supply includes three main components: an upper case, a lower case, and a gland. During assembly, the circuit board is installed on the lower case. The lower case and the upper case are fixed by snap fits and slots. The gland corresponds to the notch, and the positioning block on the gland is positioned corresponding to the positioning slot on the positioning table to prevent the gland from moving, facilitating accurate alignment. The screw is locked into the stud from the groove to achieve installation and fixation. Description of the Drawings
