DETAILED DESCRIPTION

[0027] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of devices, systems, equipment and methods consistent with some aspects of the utility model.

[0028] refer to Figure 1 As shown, the protective case 10 of the utility model is used to protect a smart mobile device, which can be a mobile phone protective case or a pad protective case. The mobile phone protective case 10 is taken as an example for description below. The protective case 10 is wrapped around the mobile phone 20, and a touch connector 100 is installed on the side of the protective case 10. The touch connector 100 is arranged corresponding to the position of the touch key (not shown) on the side of the mobile phone 20, and is used to cover the touch key (not shown) and transmit the user's touch operation to the touch key (not shown), without affecting the normal use of the touch key (not shown).

[0029] refer to Figures 2 to 4 As shown, the touch connector 100 includes a housing 1, a conductive module 2, a double-sided adhesive 3 for fixing the conductive module 2 to the housing 1, and an external bonding adhesive 4. Figure 5 As shown, the housing 1 is provided with a top wall 11 and a circle of side walls 12, the top wall 11 and the side walls 12 are together arranged to form a receiving cavity 13, and the receiving cavity 13 forms an opening 14 on the bottom surface of the housing 1, the outer surface of the side wall 12 of the housing 1 is provided with a circle of retaining grooves 15, the protective shell 10 is provided with a retaining hole (not shown), the edge of the retaining hole (not shown) is inserted into the retaining groove 15, and the touch connector 100 can be fixed on the protective shell 10.

[0030] Combination Figure 6As shown, the conduction module 2 is block-shaped and is assembled into the receiving cavity 13 from the opening 14, with the top surface of the conduction module facing the top wall 11. The double-sided adhesive 3 is arranged between the top wall 11 and the conduction module 2, and adheres the bottom surface of the top wall 11 and the top surface of the conduction module 2 to fix the conduction module 2 in the receiving cavity 13. The bottom surface of the conduction module 2 is flush with the bottom surface of the housing 1, and the strong adhesive side of the external adhesive 4 is adhered to the bottom surface of the conduction module 2 and the bottom surface of the housing 1 to seal the opening 14 and seal the conduction module 2 in the receiving cavity 13. The weak adhesive side of the external adhesive 4 adheres to the touch key (not shown) on the mobile phone 20, so that the touch connector 100 is in close contact with the touch key (not shown).

[0031] The conduction 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 the upper and lower directions, 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. During manufacturing, gold is plated on the upper surface, the lower surface, and the inner wall of the via 24 of the PCB board by electroplating to form a gold-plated layer, that is, the upper conductive sheets 22 and the lower conductive sheets 23 that are conductive to each other. The upper conductive sheet 22 is in close contact with the double-sided adhesive 3 attached to the top wall 11, and the lower conductive sheet 23 is in close contact with the outer adhesive 4 attached to the touch key (not shown). It is understandable that the double-sided adhesive tape 3 and the external bonding adhesive tape 4 are used to fix the conduction module 2 , and the conduction module 2 may also be fixed in other ways, and the double-sided adhesive tape 3 and the external bonding adhesive tape 4 are not necessary components.

[0032] The top wall 11 of the housing 1 is relatively thin, which does not affect the conduction of static electricity. The double-sided adhesive 3 and the outer adhesive 4 are also relatively thin and do not affect the conduction of static electricity. Therefore, the operation of the human body touching the housing 1 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 housing 1 can be transmitted to the multiple upper conductive sheets 22, and further transmitted to the multiple lower conductive sheets 23, so that the multiple lower conductive sheets 23 are intermittently connected, so that the touch effect of sliding contact is generated on the surface of the touch key (not shown) on the mobile phone 20. According to the functional definition of the touch key (not shown) itself, the effect of zooming in or out of the screen, or the effect of flipping up or down the screen page, etc. can be generated. In this embodiment, the housing 1 is an integral part, and its material can be plastic, metal or glass, etc., wherein the top wall 11 needs to maintain insulation properties. Therefore, if the housing 1 is made of metal material, its top wall 11 needs to be insulated, such as spraying an insulating layer, to ensure that the upper conductive sheets 22 are not conductive. As an alternative, the top wall 11 and the side wall 12 can also be two parts, which are assembled to form the housing 1. The specific materials of the top wall 11 and the side wall 12 are not limited, but the top wall 11 needs to maintain insulation properties, preferably sapphire glass.

[0033] The upper conductive sheet 22, the lower conductive sheet 23 and the via 24 aligned up and down are collectively referred to as a conductor. The specific form of the conductor is not limited. In this embodiment, the upper and lower conductive sheets 23 are conductive. Other forms may also be used, such as conductive terminals (not shown), conductive columns, separate or integrated. The conductor exposes the conductive module 2 upward to conduct with the human body, and the conductor exposes the conductive module 2 downward to conduct with the touch key (not shown). Several conductors are distributed along the longitudinal direction 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 this embodiment, 9 conductive sheets are respectively disposed on the upper and lower surfaces of the conductive module 2. Figure 7 As shown, the number and shape of the conductive sheets can be adjusted. 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 tactile sensation of sliding and gap conduction.

[0035] As mentioned above, the top wall 11 of the housing 1 adopts a thin-wall structure, which can enhance the smoothness of the contact between the human body and the conductive module 2. The thickness of the top wall 11 of the housing 1 is 0.05-0.5 mm, preferably 0.15-0.35 mm. Too thin will lead to difficulty in molding, and there will be problems of unsaturated film and deformation. The preferred thickness is conducive to touch operation and improves sensitivity. In this embodiment, the thickness of the top wall 11 is 0.23 mm. The overall length of the tactile connector 100 is 19.6 mm, the width is 5.6 mm, and the thickness is 1.85 mm; the length of the housing 1 is 19.55 mm, the width is 5.55 mm, and the thickness is 1.73 mm; the length of the double-sided tape 3 is 16.28 mm, the width is 2.96 mm, the thickness is 0.01-0.1 mm, and preferably 0.05 mm; the length of the conductive module 2 is 16.68 mm, the width is 3.2 mm, and the thickness is 1.53 mm; the length of the external bonding adhesive 4 is 19.25 mm, the width is 5.25 mm, and the thickness is 0.01-0.1 mm, preferably 0.05 mm; the thickness tolerance of the double-sided tape 3 and the external bonding adhesive 4 is 0.01 mm, and the size tolerance of other components is 0.1 mm.

[0036] The above are only preferred implementation modes of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
