Detailed Description

The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to 6, the compact power supply of this embodiment includes a circuit board and a battery case, the battery case includes a main body portion 100 for accommodating the circuit board and an end cap 200 for encapsulating a wiring region, in order to facilitate installation and connection of wires, the main body portion 100 is provided with a wire leading-out base 300 at an outer side of the wiring region for matching with the end cap 200 to lead out a wired wire from the case and compressing the wire, the wire leading-out base 300 and the end cap 200 are connected by screws, and the end cap 200 and the wire leading-out base 300 are provided with a mounting hole 201 and a screw hole 307 which are matched.

The casing of power is the rectangle structure generally, and when openly upwards horizontal placement, the casing has mutually perpendicular's length direction and width direction on the horizontal plane, and the direction perpendicular to the horizontal plane is the thickness direction of casing.

The main body part 100 is detachably connected with the lead-out base 300, the detachable connection can be realized through the simplest fastening connection, in order to facilitate assembly, the lead-out base 300 is connected by a buckle in the embodiment, two sides of the lead-out base 300 in the width direction of the shell are respectively provided with a leg part 301, the free end of each leg part 301 is bent towards one side to form a hook part 302, and the hook parts 302 of the two leg parts 301 are arranged oppositely; the body part 100 is provided with guide grooves 101 respectively at both sides in the width direction of the housing to be fitted with the leg parts 301, the ends of the guide grooves 101 are provided with grooves 102, and the hook parts 302 are caught in the grooves 102.

The guide groove 101 is open at the bottom in the thickness direction of the housing, so that the wire drawing base 300 can be more easily detached, and the leg 301 is rotated downward to exit the guide groove 101.

The wire drawing base 300 is provided with a stopper 303 pressing the main body portion in the thickness direction of the case between the two leg portions 301. To facilitate the removal, the edge 106 of the free end of the blocking portion does not exceed the entrance of said guide groove 101. So that the wire-drawing base 300 can be pivoted about the edge 106 to withdraw the hook 302 from the groove 102, as shown in fig. 5 and 6.

The body portion 100 is provided with a projection 103 engaged with the stopper 303, and the projection 103 is provided with an open screw hole 104. So that the main body portion 100 can be mounted and fixed after the lead wire drawing base 300 is removed. The blocking portion 303 is provided with a boss 305 to be caught in the screw hole.

To facilitate fitting mounting, the distance in the housing width direction of the inlet regions 105 of the two guide grooves 101 becomes gradually smaller along the wire lead-out direction. In this embodiment, the inlet area 105 is a horizontal inclined surface, and may be an arc surface.

The housing is generally made of plastic or metal, so the leg 301 has elasticity, in this embodiment, the distance between the ends of the two hooks 302 is smaller than the maximum distance of the two guide grooves 101 in the width direction of the housing, in this embodiment, the straight sections behind the entrance area 105 are both the maximum distance, in this embodiment, when the straight sections of the guide grooves 101 slide, the hooks 302 need to be spread and then clamped into the grooves 102, and are less prone to coming off, and the installation is firmer.
