Specifically, the designed emitting part 121 is placed in a first mold, the conducting wire 123 is electrically connected to the emitting part 121, the emitting part 121 and the conducting wire 123 are fixed in the first mold, a material is injected into the first mold, the base 122 is obtained after the material is cured, and the base 122 plays a role in fixing the emitting part 121 and the conducting wire 123 and sealing, and is formed in one step; subsequently, the shell 11 and the antenna emission mechanism 12 are placed in a second mold for secondary molding, and after the shell 11 and the antenna emission mechanism 12 which is molded in the first step are placed in the second mold, the shell 11 and the antenna emission mechanism 12 are cast together by secondary casting, which is secondary molding, so that the antenna 10 of the embodiment of the application is obtained, and the antenna 10 with explosion-proof performance is obtained by secondary casting, so that the explosion-proof effect can be realized.

In the embodiment of the present application, the base 122, the end cap 14 and the screws of the antenna 10 obtained by the secondary molding are assembled together to form a finished product, that is, the wireless explosion-proof antenna 10 in fig. 1, so that an explosion-proof effect can be achieved.

The emitting member 121 is also obtained by casting, specifically, the electronic component is placed in a third mold, then plastic is injected into the third mold, and the plastic is coated outside the electronic component and cured to obtain a housing, so that the injection molded emitting member 121 is obtained.

The lead 123 is also obtained by casting, specifically, the guide core is fixed in the fourth mold, then plastic is injected into the fourth mold, and the plastic is coated outside the guide core and then cured to obtain the protective layer, so that the injection molded lead 123 is obtained.

The present invention is not intended to be limited to the particular embodiments shown and described, but is to be accorded the widest scope consistent with the principles and novel features herein disclosed.
