DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the 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 present utility model. Instead, they are merely examples of devices, systems, devices, and methods consistent with some aspects of the present utility model.

[0024] Referring to Figure 1 As shown, the protective case 100 of the present utility model is used to protect a smart mobile device, which can be a mobile phone case or a Pad case. Hereinafter, the mobile phone case 100 will be taken as an example for description. The protective case 100 is wrapped outside the mobile phone (not shown). The protective case 100 includes a housing 1 and a tactile connector 2 provided on the side 11 of the housing 1. The position of the tactile connector 2 corresponds to the touch keys (not shown) on the side of the mobile phone (not shown), and is used to block the touch keys (not shown) and conduct the user's touch operation to the touch keys (not shown).

[0025] Referring to Figures 2 to 4 As shown, the tactile connector 2 is generally in the shape of a strip block, and includes a housing 21, a conduction module 22, and a double-sided adhesive 23 for fixing the conduction module 22 inside the housing 21. The housing 21 is provided with a top wall 211 and a surrounding side wall 212. The top wall 211 and the side wall 212 jointly enclose a receiving cavity 213, and the receiving cavity 213 forms an opening 214 on the bottom side of the housing 21. The conduction module 22 is assembled into the receiving cavity 213 from the opening 214, and the top surface of the conduction module 22 faces the top wall 211. The double-sided adhesive 23 is provided between the top wall 211 of the housing 21 and the conduction module 22, and adheres to the bottom surface of the top wall 211 and the top surface of the conduction module 22 to fix the conduction module 22 in the receiving cavity 213.

[0026] The conduction module 22 is a PCB board, and includes a substrate 221, a plurality of upper conductive sheets 222 provided on the upper surface of the substrate 221, a plurality of lower conductive sheets 223 provided on the lower surface of the substrate 221, and a plurality of vias 224. The upper conductive sheets 222 and the lower conductive sheets 223 are arranged in a one-to-one correspondence up and down. The vias 224 penetrate through the upper conductive sheets 222, the substrate 221, and the corresponding lower conductive sheets 223 to electrically conduct the upper conductive sheets 222 and the lower conductive sheets 223 arranged in a corresponding manner up and down. During manufacturing, the upper surface, the lower surface, and the inner wall of the via 224 of the PCB board are plated with gold by electroplating to form a gold plating layer, which is the upper conductive sheet 222 and the lower conductive sheet 223 that are electrically connected to each other. The double-sided adhesive 23 covering the top surface of the conduction module 22 can completely cover the upper conductive sheets 222.

[0027] The upper conductive sheet 222, the lower conductive sheet 223, and the via 224 that are vertically aligned together are referred to as a conductor. The specific form of the conductor is not limited. In this embodiment, it is a conductive sheet that is electrically connected, and other forms can also be used, such as conductive terminals (not shown), conductive posts, which can be separate or integrated. The top wall 211 of the housing 21 has a relatively thin wall thickness, which does not affect the conduction of static electricity. The double-sided tape 23 is also relatively thin and does not affect the conduction of static electricity. The conductor exposes upward from the conduction module 22 and is electrically connected to the housing 21 and the human body through the double-sided tape 23. The conductor exposes downward from the conduction module 22 and is electrically connected to the touch key (not shown), or can be electrically connected to the touch key (not shown) through another double-sided tape (not shown) that bonds the touch key (not shown) and the conduction module 22. In the tactile connector 2, the conduction module 22 is in the form of a PCB board, which is smaller in volume and can reduce the cost of the product. A number of conductors are distributed along the longitudinal direction of the tactile connector 2. The number and shape of the conductive sheets can be adjusted, but there are at least two to identify the tactile sensation of sliding and gap conduction.

[0028] When in use, the sliding of the user's finger on the top wall 211 of the housing 21 can be transmitted to multiple upper conductive sheets 222, and further conducted to multiple lower conductive sheets 223, so that multiple lower conductive sheets 223 are conductively connected at intervals. The lower conductive sheet 223 is electrically connected to the touch key (not shown) on the mobile phone (not shown). Thus, a tactile effect of sliding contact is generated on the surface of the touch key (not shown). According to the function definition of the touch key (not shown) itself, control effects such as screen magnification or reduction, or the effect of scrolling up or down the screen page can be generated.

[0029] Continue to refer to Figure 4 As shown, since the wall thickness of the top wall 211 is relatively thin, the wall thickness of the corresponding side wall 212 is also relatively thin, otherwise it will cause shrinkage marks on the surface when the housing 21 is molded. And the length and width dimensions of the receiving cavity 213 are both larger than the length and width dimensions of the conduction module 22. To prevent the conduction module 22 from shaking inside the receiving cavity 213, a number of positioning ribs 216 are provided on the inner wall surface 215 of the side wall 212. The positioning ribs 216 extend up and down, and a number of positioning ribs 216 are distributed on the opposite sides of the receiving cavity 213 along the longitudinal direction of the receiving cavity 213. In this embodiment, four positioning ribs 216 are provided on one side of the receiving cavity 213. The positioning ribs 216 protrude from the inner wall surface 215 towards the conduction module 22 inside the receiving cavity 213, which can limit the movement range of the conduction module 22 inside the receiving cavity 213 and prevent the conduction module 22 from shaking. In this embodiment, the size of the positioning ribs 216 protruding from the inner wall surface 215 towards the inside of the receiving cavity 213 is 0.22 mm.

[0030] Combined with Figure 5As shown, when the conduction module 22 is centrally disposed in the receiving cavity 213, the clearance dimension between the positioning ribs 216 and the conduction module 22 is 0.03 mm. Even if the conduction module 22 is disposed closely against a number of positioning ribs 216 on one side, the maximum clearance dimension between it and a number of positioning ribs 216 on the other side is only 0.06 mm. Such a dimension setting can effectively prevent the conduction module 22 from shaking. The bottom surface of the positioning rib 216 is an inclined guiding surface 217, which can guide the conduction module 22 into the receiving cavity 213. The cross section of the positioning rib 216 is semi-circular, which can avoid scratching the conduction module 22.

[0031] Continue to refer to Figure 5 As shown, the side 11 of the housing 1 is provided with a through holding hole 12, and an outer surface of a side wall 212 of the housing 21 of the tactile connector 2 is provided with a circumferentially recessed groove 218 along its circumference. The edge 121 of the holding hole 12 is snapped into the groove 218, and the tactile connector 2 can be reliably fixed to the protective housing 100.

[0032] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of protection of the present invention.
