[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] In the description of the present application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated components or elements must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present application.

[0032] In the assembling process of the surface light source, the LED lamp plate is installed into the mounting area on the front side of the injection molding part, and the LED lamp plate is opposite to the light guide plate in the mounting area. The wire on the LED lamp plate needs to pass out of the injection molding part and be connected with the external power supply. At present, there are the following two schemes: one is that the wire directly passes out of the injection molding part, in which scheme, there is a gap between the wire and the injection molding part, and light leakage and the risk of water vapor entering may occur; the other is that a power connector is arranged at the wire outlet end, and the power connector is installed on the injection molding part or the LED lamp plate, so as to realize the sealing between the wire and the injection molding part after the wire passes out of the injection molding part. In this scheme, since the power connector generally has a plurality of connection interfaces, the sealing reliability of the connection between the power connector and the injection molding part or the LED lamp plate is poor, and the risk of light leakage and water vapor entering may also occur. At the same time, in the above schemes, since the operation space at the connection between the injection molding part and the wire is limited, there are problems of complex operation process and poor consistency of manual operation. Based on this, the utility model provides a surface light source power supply wire outlet sealing structure, which has solved the above problems existing in the prior art.
