DETAILED DESCRIPTION

[0016] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0018] like Figure 1 to Figure 3 As shown, a power supply line connection structure of a lamp in a preferred embodiment of the utility model, the lamp includes a lamp housing 1, a light source board 2 and a plug 3 arranged at the end of the lamp housing 1, the power supply line connection structure includes a flexible flat cable 4 (FFC), a wire passing opening 11 is provided between the plug 3 and the end surface of the lamp housing 1, a wire passing groove 321 is provided between the bottom surface of the lamp housing 1 and the plug 3, the input end of the flexible flat cable 4 is connected to the power input end of the light source board 2, the flexible flat cable 4 passes through the wire passing opening 11 and the wire passing groove 321, and the output end of the flexible flat cable 4 extends out of the plug 3.

[0019] The utility model adopts a flexible flat cable 4 and cooperates with the wire groove 321 between the bottom surface of the lamp housing 1 and the plug 3, which facilitates wiring between the lamp housing 1 and the plug 3. The flexible flat cable 4 itself has a small thickness, which effectively reduces the thickness of the power supply line connection structure, thereby reducing the overall thickness of the lamp, and the lamp can be used in different scenarios.

[0020] Exemplarily, the plug 3 includes an end plate 31 and a positioning plate 32, and mounting grooves 12 are provided on both sides of the bottom of the lamp housing 1. The positioning plate 32 is inserted into the mounting grooves 12, and the end plate 31 is abutted against the end surface of the lamp housing 1. The wire passing opening 11 is opened at the end of the lamp housing 1, and the wire passing groove 321 is opened on the top surface of the positioning plate 32. The flexible flat cable 4 is clamped between the wire passing groove 321 of the positioning plate 32 and the bottom surface of the lamp housing 1. The setting of the wire passing opening 11 and the wire passing groove 321 does not require additional wire passing space, thereby ensuring that the overall thickness of the lamp is small, and facilitating the installation and positioning of the flexible flat cable 4, thereby improving assembly efficiency.

[0021] Exemplarily, a positioning groove 13 is formed on the bottom surface of the lamp housing 1 , and a positioning protrusion 322 is formed on the top surface of the positioning plate 32 to engage with the positioning groove 13 , thereby improving the connection stability between the plug 3 and the lamp housing 1 .

[0022] Furthermore, the positioning protrusion 322 is a wedge block that tilts downward from the end surface of the lamp housing 1 toward the center of the lamp housing 1, which facilitates the engagement of the positioning protrusion 322 with the positioning groove 13, further improves the connection firmness between the plug 3 and the lamp housing 1, and avoids accidental activation of the plug 3 after assembly.

[0023] Specifically, two positioning protrusions 322 are provided and are respectively disposed on both sides of the positioning groove 13 , so as to further improve the installation stability of the flexible flat cable 4 .

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
