DETAILED DESCRIPTION

[0027] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. The following description is presented in terms of exemplary embodiments, which should not be interpreted in a restrictive sense. Rather, these exemplary embodiments are described in detail to enable one of ordinary skill in the art to practice the inventive concepts disclosed herein.

[0028] Referring to Figure 1 As shown, the protective shell 10 of the present application is used to protect a smart mobile device, which can be a mobile phone protective shell or a Pad protective shell. The following description will take the mobile phone protective shell 10 as an example. The protective shell 10 is wrapped around the mobile phone 20. The protective shell 10 is provided with a touch connector 100 on the side edge thereof. The touch connector 100 is arranged in correspondence with the position of the touch keys (not shown) on the side surface of the mobile phone 20. The touch connector 100 is used to shield the touch keys (not shown) and to transmit the touch operation of the user to the touch keys (not shown), without affecting the normal use of the touch keys (not shown).

[0029] Referring to Figures 2 to 4 As shown, the touch connector 100 includes a shell 1, a conductive module 2, a double-sided adhesive 3 for fixing the conductive module 2 to the shell 1, and an outer adhesive 4. Figure 5 As shown, the shell 1 is provided with a top wall 11 and a ring-shaped side wall 12. The top wall 11 and the side wall 12 together define a receiving cavity 13. The receiving cavity 13 forms an opening 14 on the bottom surface of the shell 1. The outer surface of the side wall 12 of the shell 1 is provided with a ring-shaped retaining groove 15. The protective shell 10 is provided with a retaining hole (not shown). The edge of the retaining hole (not shown) is clamped into the retaining groove 15. The touch connector 100 can be fixed to the protective shell 10.

[0030] In combination Figure 6As shown, the conductive module 2 is in a block shape, assembled into the accommodating cavity 13 from the opening 14, and the top surface of the conductive module faces the top wall 11. The double-sided adhesive 3 is arranged between the top wall 11 and the conductive module 2, and adheres the bottom surface of the top wall 11 and the top surface of the conductive module 2 to fix the conductive module 2 in the accommodating cavity 13. The bottom surface of the conductive module 2 and the bottom surface of the shell 1 are flush, and the outer adhesive 4 is adhered to the bottom surface of the conductive module 2 and the bottom surface of the shell 1 to seal the opening 14 and seal the conductive module 2 in the accommodating cavity 13. The weakly adhesive side of the outer adhesive 4 is adhered to the touch key (not shown) on the mobile phone 20 to make the touch connector 100 in close contact with the touch key (not shown).

[0031] The conductive module 2 is a PCB board, including a substrate 21, a plurality of upper conductive sheets 22 arranged on the upper surface of the substrate 21, a plurality of lower conductive sheets 23 arranged on the lower surface of the substrate 21, and a plurality of vias 24. The upper conductive sheets 22 and the lower conductive sheets 23 are arranged one by one in correspondence with each other, and the vias 24 penetrate the upper conductive sheets 22, the substrate 21, and the corresponding lower conductive sheets 23 to electrically conduct the corresponding upper conductive sheets 22 and lower conductive sheets 23. In manufacturing, gold plating is used to form a gold plating layer on the inner walls of the upper surface, the lower surface, and the vias 24 of the PCB board, that is, the upper conductive sheets 22 and the lower conductive sheets 23 are in electrical conduction with each other. The upper conductive sheets 22 are in close contact with the double-sided adhesive 3 adhered to the top wall 11, and the lower conductive sheets 23 are in close contact with the outer adhesive 4 adhered to the touch key (not shown). It can be understood that the double-sided adhesive 3 and the outer adhesive 4 are used to fix the conductive module 2, and the conductive module 2 can also be fixed by other methods, and the double-sided adhesive 3 and the outer adhesive 4 are not essential elements.

[0032] The top wall 11 of the shell 1 is relatively thin and does not affect the conduction of static electricity, and the double-sided adhesive 3 and the outer adhesive 4 are also relatively thin and do not affect the conduction of static electricity, so that the operation of touching the shell 1 by the human body can be transmitted to the touch key (not shown) on the mobile phone 20 through the touch connector 100. Specifically, the sliding of the user's finger on the top wall 11 of the shell 1 can be transmitted to a plurality of upper conductive sheets 22, and further conducted to a plurality of lower conductive sheets 23, so that the plurality of lower conductive sheets 23 are intermittently conducted, thereby generating a sliding contact touch effect on the surface of the touch key (not shown) on the mobile phone 20. According to the function definition of the touch key (not shown) itself, the effect of screen magnification or reduction, or the effect of flipping up or down the screen page, and other control effects can be generated. In this embodiment, the shell 1 is a whole piece, and its material can be plastic, metal, or glass, etc. The top wall 11 needs to maintain insulation properties, so if the shell 1 uses a metal material, the top wall 11 needs to be insulated, for example, by spraying an insulating layer, to ensure that the upper conductive sheets 22 are not in conduction with each other. As an alternative, the top wall 11 and the side wall 12 can also be two parts assembled to form the shell 1, and the specific material of the top wall 11 and the side wall 12 is not limited, but the top wall 11 needs to maintain insulation properties, and sapphire glass is preferred.

[0033] The upper and lower conductive sheets 22, 23 and the via 24 are collectively referred to as a conductive body, and the specific form of the conductive body is not limited. In the embodiment, the upper and lower conductive sheets 23 are conductive, and other forms such as conductive terminals (not shown), conductive posts, separate or integrated conductive bodies can also be used. The conductive body is exposed upward to make the conductive module 2 conductive to the human body, and the conductive body is exposed downward to make the conductive module 2 conductive to the touch key (not shown). A plurality of conductive bodies are distributed along the length of the touch connector 100. In the touch connector 100, the conductive module 2 is in the form of a PCB board, which is smaller in size and can reduce the cost of the product.

[0034] In the embodiment, the upper and lower surfaces of the conductive module 2 are respectively provided with 9 conductive sheets, as shown in Figure 7 The number and shape of the conductive sheets can be adjusted, and in other embodiments, the number of conductive sheets 25 on the upper surface of the conductive module 2 can be 3, 5 or multiple rows, but at least two to identify the sliding touch and gap conduction.

[0035] As described above, the top wall 11 of the shell 1 is in a thin wall structure, which can enhance the smoothness when the human body contacts the conductive module 2. The thickness of the top wall 11 of the shell 1 is 0.05-0.5mm, preferably 0.15-0.35mm, too thin will cause molding difficulty, and there will be problems of unsatisfied film and deformation, and the preferred thickness is conducive to touch operation and improves sensitivity. In the embodiment, the thickness of the top wall 11 is 0.23mm. The overall length of the touch connector 100 is 19.6mm, the width is 5.6mm, and the thickness is 1.85mm; the length of the shell 1 is 19.55mm, the width is 5.55mm, and the thickness is 1.73mm; the length of the double-sided adhesive 3 is 16.28mm, the width is 2.96mm, and the thickness is 0.01-0.1mm, preferably 0.05mm; the length of the conductive module 2 is 16.68mm, the width is 3.2mm, and the thickness is 1.53mm; the length of the outer adhesive 4 is 19.25mm, the width is 5.25mm, and the thickness is 0.01-0.1mm, preferably 0.05mm; the thickness tolerance of the double-sided adhesive 3 and the outer adhesive 4 is 0.01mm, and the size tolerance of other elements is 0.1mm.

[0036] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
