In addition, when the earphone box 40 shielded by the film-coating shielding jig 1 is coated by, for example, a nano-coating technique, the portion 402 to be coated of the earphone box 40 is coated with a film by being openly exposed to form a protective film layer for water resistance, sweat resistance, and oil resistance. Meanwhile, the non-coated part 401 of the earphone box 40 is shielded in a sealed manner and is not coated, so that the problem that the non-coated part 401 of the earphone box 40 has different colors and the like is solved, and the requirement of a user for pursuing extremely attractive appearance or decoration effect is met.

For example, as shown in fig. 2, a semi-finished earphone box of a wireless earphone is taken as the earphone box 40, and the earphone box 40 may include a charging cabin 41 configured with electronic components 410 and a housing 42 disposed outside the charging cabin 41. That is, the earphone box 40 of the present invention refers to a semi-finished earphone box in which the charging chamber is not closed yet and the electronic component 410 is exposed. It can be understood that the electronic component 410 in the charging chamber 41 of the earphone box 40 needs to be used as the portion to be plated 402 of the earphone box 40 to be plated with a protective film layer, because the electronic component is easily contaminated by water stain, sweat stain, oil stain, and the like; the outer surface of the outer shell 42 of the earphone box 40 is used as the non-plated part 401 of the earphone box 40 to prevent the problem of color difference caused by plating because the outer surface needs to maintain the original beauty.

It should be noted that, although the present application takes a semi-finished earphone case of a wireless earphone (such as a TWS bluetooth earphone) as an example to illustrate the advantages and features of the film-coating shielding fixture 1, it is only an example and does not limit the scope of protection of the present application. For example, in other examples of the present application, the earphone box 40 may also be implemented as a box for containing other electronic devices.

In particular, in an application scenario of a semi-finished earphone box of a wireless earphone, the casing 42 of the earphone box 40 may have a containing space 421 and an opening 422, wherein the opening 422 of the casing 42 communicates the containing space 421 of the casing 42 with an external space of the casing 42, and the charging chamber 41 is contained in the containing space 421 of the casing 42, so as to expose the electronic component 410 of the charging chamber 41 through the opening 422 of the casing 42.

It is understood that the portion of the earphone box 40 corresponding to the opening 422 of the housing 42 is implemented as the opening 403 of the earphone box 40, for example, the top of the housing 42 as shown in fig. 2. In this way, when the shielding sleeve 20 of the film-coating shielding jig 1 is sleeved on the opening 403 of the earphone box 40, and the shielding cover 10 is coupled to the shielding sleeve 20 after being covered on the housing 42 of the earphone box 40, the outer surface of the housing 42 of the earphone box 40 is hermetically shielded by the film-coating shielding jig 1 to serve as the non-film-coating portion 401 of the earphone box 40, and the electronic component 410 in the charging cabin 41 of the earphone box 40 is not shielded by the film-coating shielding jig 1 to serve as the to-be-film-coating portion 402 of the earphone box 40.

It should be noted that, according to the above-mentioned embodiment of the present application, the hard shell 21 of the shielding sleeve 20 of the film-coating shielding jig 1 may be made of, but not limited to, hard plastic, and the soft lining 22 of the shielding sleeve 20 may be made of, but not limited to, soft rubber material. For example. The hard plastic of the present application may be, but is not limited to, implemented as ABS resin, PC (polycarbonate), or PVC (polyvinyl chloride), etc., and the soft plastic material may be, but is not limited to, implemented as TPU (thermoplastic polyurethane elastomer rubber), or TPR (thermoplastic elastomer), etc.

Preferably, the coating through hole 2101 of the hard case 21 of the shielding sleeve 20 is chamfered to form a bell mouth structure, so as to prevent the shielding sleeve 20 from shielding the charging compartment 41 of the earphone box 40, which helps to promote the circulation of coating materials.

More preferably, as shown in fig. 3A and 3B, the hard case 21 of the shielding sleeve 20 may include an annular top wall 211, an annular inner wall 212 extending downward from an inner periphery of the annular top wall 211, and an annular outer wall 213 extending downward from an outer periphery of the annular top wall 211, wherein an inner surface of the annular inner wall 212 defines the plated through hole 2101 of the hard case 21, and the annular inner wall 212 and the annular outer wall 213 are spaced apart from each other to define the annular sleeve groove 2102 of the hard case 21 by an outer surface of the annular inner wall 212 and an inner surface of the annular outer wall 213.

According to the above-mentioned embodiments of the present application, the shielding cover 10 of the filming shielding jig 1 is preferably made of an elastic material, for example, the elastic material of the shielding cover 10 may be, but is not limited to be, implemented by latex, rubber, plastic or aluminum foil.

Preferably, as shown in fig. 4A and 4B, the shielding cover 10 of the film-coating shielding jig 1 may be, but not limited to, implemented as an air balloon, and as the shielding cover 10 may include an air bag 11 and an elastic ring 12 disposed at a mouth of the air bag 11, wherein the air bag 11 of the shielding cover 10 is adapted to wrap the outer shell 42 of the earphone box 40, and the elastic ring 12 of the shielding cover 10 is captively sleeved on the hard shell 21 of the shielding cover 20 to sealingly connect the shielding cover 10 and the shielding cover 20, so that the air bag 11 of the shielding cover 10 is sealingly wrapped on an outer surface of the outer shell 42 of the earphone box 40. It will be appreciated that in other examples of the present application, the shield 10 may also be sealably connected to the shield sleeve 20, such as by strapping or the like. It is noted that the elastic ring 12 of the shield 10 is preferably implemented as a rubber ring.

More preferably, the natural length of the elastic ring 12 of the shield 10 is smaller than the outer circumference of the annular outer wall 213 of the hard shell 21 of the shield 20, so that the elastic ring 12 of the shield 10 can tightly bind to the outer surface of the annular outer wall 213 of the hard shell 21 by its elastic deformation, thereby sealingly connecting the shield 10 and the shield 20.

It should be noted that, as shown in fig. 2 to 4B, the hard case 21 of the shielding sleeve 20 of the filming shielding jig 1 of the present application may further include one or more anti-dropping elements 214, wherein the anti-dropping elements 214 are disposed on the annular outer wall 213 to prevent the shielding cover 10 from being unintentionally or accidentally dropped from the hard case 21 of the shielding sleeve 20.

Specifically, the anti-slip part 214 of the hard case 21 may be, but is not limited to, implemented as a protrusion 2140 extending outward from the outer surface of the annular outer wall 213 of the hard case 21, for blocking the elastic ring 12 of the shield cover 10 from sliding on the outer surface of the annular outer wall 213, so as to prevent the elastic ring 12 of the shield cover 10 from sliding off the annular outer wall 213 of the hard case 21.

Preferably, the protrusion 2140 extends annularly along the outer circumference of the annular outer wall 213 to form a ring buckle 2141 surrounding the annular groove 2102 of the hard case 21, so as to enhance the sealing performance of the connection between the shield cover 10 and the shield sleeve 20 while preventing the elastic ring 12 of the shield cover 10 from slipping off.

Exemplarily, in an example of the present application, as shown in fig. 3A to 4B, the one or more anti-release members 214 of the hard case 21 of the shield cover 20 may be implemented as three anti-release members 214, wherein three anti-release members 214 are arranged at intervals on the outer surface of the annular outer wall 213 to form an annular groove 2142 between two adjacent anti-release members 214, so that the elastic ring 12 of the shield cover 10 can be buckled in the annular groove 2142, which helps to further enhance the joint strength and the sealing performance between the shield cover 10 and the shield cover 20.

Of course, in other examples of the present application, the anti-slip part 214 of the hard shell 21 of the shielding sleeve 20 may also be implemented as a groove recessed inwards from the outer surface of the annular outer wall 213 of the hard shell 21 for accommodating the elastic ring 12 of the shielding cover 10, and still function to prevent the elastic ring 12 of the shielding cover 10 from slipping off the annular outer wall 213 of the hard shell 21.

It should be noted that, as shown in fig. 2 to fig. 4B, the electronic component 410 in the charging compartment 41 of the earphone box 40 generally includes a flexible circuit board 411 (such as a flexible board, etc.), and the flexible circuit board 411 generally has a plurality of connection sites 4110 thereon for electrically connecting with a wireless earphone to charge the wireless earphone, and the connection sites 4110 on the flexible circuit board 411 also need to be the non-plated portion 401 of the earphone box 40 and cannot be plated with a film. Considering that the length of the flexible printed circuit 411 of the charging cabin 41 is relatively long, the flexible printed circuit 411 can usually extend out of the charging cabin 41, so that the application can fold the flexible printed circuit 411 to make the connection point 4110 be located outside the housing 42 of the earphone box 40, and then shield the connection point 4110 by the shielding cover 10 of the film-plating shielding jig 1, so as to prevent the connection point 4110 of the flexible printed circuit 411 from being plated with a film.

Preferably, the hard case 21 of the shielding case 20 may further include one or more preformed grooves 215, wherein the preformed grooves 215 are disposed on the outer surface of the annular outer wall 213 for accommodating the folded flexible circuit board 411, so that the folded flexible circuit board 411 passes through the anti-falling part 214 to prevent the folded flexible circuit board 411 from forming a gap between the shielding cover 10 and the shielding case 20 to affect the sealing effect between the shielding cover 10 and the shielding case 20.
