The injection molded housing 100 replaces the existing positioning structure of the step stop and the limiting rib by accommodating the protrusion 111 in the recessed portion 122 during positioning, thereby preventing the generation of thick and thin offset during injection molding, reducing the appearance processing process, and thus reducing the production cost.

[0039] In this embodiment, the first half shell 110 and the second half shell 120 are both surrounded on all sides and open at one end. The first half shell 110 and the second half shell 120 can be fitted together, and the internal space is used to accommodate the core of the product with an injection molded shell.

[0040] It should be noted that the end wall of the first half shell 110 provided with the raised portion 111 refers to the end face of the first half shell 110 which is surrounded by a structure close to the opening, and the end wall of the second half shell 120 provided with the recessed portion 122 refers to the end face of the first half shell 120 which is surrounded by a structure close to the opening. In addition, the raised portion 111 and the recessed portion 122 are respectively located in the middle of the end face, so as to prevent problems such as inconvenience in positioning or affecting the appearance when they are located at the edge of the end face.

[0041] In this embodiment, in order to improve the positioning efficiency of the first half shell 110 and the second half shell 120, the raised portion 111 can be made into a triangular boss structure, and the recessed portion 122 can be made into a triangular groove structure.
