[0002] For current mobile intelligent devices, such as mobile phones, tablets, etc., touch keys are usually provided on their sides. Some controls of the mobile intelligent device can be achieved by touching the touch keys, such as waking up, adjusting the volume, etc. Generally, the protective cases of existing mobile intelligent devices are provided with openings for exposing the touch keys, so that the touch keys are exposed for convenient touch operation by the user. However, such openings will affect the waterproof performance of the protective case. If the mobile phone protective case is not provided with openings and completely covers the touch keys, it will affect the touch operation of the user. Therefore, the applicant is researching and developing a connector capable of conducting touch operations, which can be disposed on the protective case to cover the touch keys and can operate the touch keys normally.

Detailed implementation

[0025] Here, the exemplary embodiments will be described in detail, and the examples 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 invention. On the contrary, they are merely examples of devices, systems, equipment, and methods consistent with some aspects of the present invention.

[0026] Refer to Figure 1 As shown, the protective case 100 of the present invention is used to protect intelligent mobile devices, which can be a mobile phone case or a Pad case. Hereinafter, the mobile phone case 100 will be taken as an example for illustration. The protective case 100 is wrapped outside the mobile phone (not shown), and the protective case 100 includes a housing 1 and a tactile connector 2 provided on the side 11 of the housing 1.

[0027] Refer to Figures 2 to 4 As shown, the tactile connector 2 is generally in a strip shape, and includes an outer shell 21, a conduction module 22, and a double-sided tape 23 that fixes the conduction module 22 into the outer shell 21. The outer shell 21 is provided with a top wall 211 and a circle of side walls 212. The top wall 211 and the side walls 212 jointly enclose to form a receiving cavity 213, and an opening 214 is formed on the bottom side of the outer shell 21 for the receiving cavity 213. 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 tape 23 is disposed between the top wall 211 of the outer shell 21 and the conduction module 22, and bonds 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.

[0028] The conduction module 22 is a PCB board, including a substrate 221, a plurality of upper conductive sheets 222 arranged on the upper surface of the substrate 221, a plurality of lower conductive sheets 223 arranged 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 one by one in the upper and lower directions, and the vias 224 penetrate 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 the upper and lower directions. During manufacturing, gold is plated on the upper surface, the lower surface, and the inner wall of the vias 224 of the PCB board by electroplating to form a gold plating layer, namely, the upper conductive sheets 222 and the lower conductive sheets 223 that are conductive to each other. The double-sided adhesive 23 covering the top surface of the conduction module 22 can completely cover the upper conductive sheet 222. The conduction module 22 is in the form of a PCB board, which is smaller in size and can reduce the cost of the product.

[0029] Combination Figure 1 , Figures 5 to 6 As shown, the side edge 11 of the housing 1 is provided with a holding hole 12, and the holding hole 12 is arranged corresponding to the touch key (not shown) on the side of the mobile phone (not shown), and the side wall 212 of the touch connector 2 is provided with a circle of holding grooves 215 along its circumference, and the touch connector 2 is inserted into the holding hole 12, and the holding hole 12 is provided with a circle of edges 121 that are inserted into the holding groove 215, so that the touch connector 2 can be fixed on the housing 1. The touch connector 2 can cover the touch key (not shown) of the mobile phone (not shown), and the lower conductive sheet 223 of the touch connector 2 is electrically connected with the touch key (not shown) of the mobile phone (not shown), and this electrical connection includes the way of electrical connection through a thin double-sided tape (not shown).

[0030] When the protective case 100 is used with a mobile phone (not shown), since the top wall 211 of the shell 21 is relatively thin, it does not affect the conduction of static electricity. The double-sided adhesive tape 23 is also relatively thin and does not affect the conduction of static electricity. The sliding of the user's finger on the top wall 211 of the shell 21 can be transmitted to the multiple upper conductive sheets 222, and further transmitted to the multiple lower conductive sheets 223, so that the multiple lower conductive sheets 223 are intermittently connected. The lower conductive sheets 223 are electrically connected to the touch keys (not shown) on the mobile phone (not shown), so that a tactile effect of sliding contact is generated on the surface of the touch keys (not shown). According to the functional definition of the touch keys (not shown) themselves, control effects such as the effect of zooming in or out the screen, or the effect of flipping up or down the screen page, can be generated. And the user's touch operation is transmitted to the touch keys (not shown)

[0031] The upper conductive sheet 222, the lower conductive sheet 223, and the via 224 that are vertically aligned are collectively 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. Other forms can also be adopted, such as conductive terminals (not shown), conductive posts, which can be separate or integrated. The conductor exposes upward from the conduction module 22 and is electrically connected to the human body through the double-sided tape 23 and the housing 21. The conductor exposes downward from the conduction module 22 and is electrically connected to the touch key (not shown). A number of conductors are distributed along the longitudinal direction of the touch connector 2. The number and shape of the conductors can be adjusted, but there are at least two to identify the sliding touch and gap conduction.

[0032] Continuing to refer to Figure 5 and Figure 6 As shown, the touch connector 2 is assembled outward from the inner side of the side 11 with its top surface facing outward. The thickness of the edge 121 of the holding hole 12 is less than the depth of the holding hole 12, and the edge 121 is made of a flexible material. The edge 121 can undergo elastic deformation and snap into the holding groove 215. A ring of ribs 122 is provided on the inner side surface of the edge 121 at its free end. As mentioned above, when the edge 121 is arranged in a whole circle, it is annular, and the ribs 122 are arranged in a whole circle along the inner circumference of the edge 121. During the process of assembling the touch connector 2 into the holding hole 12, the ribs 122 can contact the inner wall surface of the holding groove 215 of the touch connector 2. The setting of the ribs 122 can ensure that the edge 121 is uniformly stressed in a whole circle when contacting the touch connector 2, and form an elastic contact, which can center the touch connector 2 in the holding hole 12 and prevent the touch connector 2 from skewing. Among them, the cross-section of the rib 122 is semicircular with a radius of 0.1 mm. As another alternative, referring to Figure 7 As shown, the cross-section of the rib 122' of the edge 121' can also be other shapes, such as triangular, with a height of 0.1 mm.

[0033] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of protection of the present invention.
