[0037] Reinforcement type control terminals usually refer to reliable devices that can operate stably in special environments or conditions. The existing separate buttons are made of all-plastic materials, and when the buttons are installed on the panel of the control terminal, there is a risk that electromagnetic waves or water can penetrate through the installation area between the buttons and the panel and enter the operation terminal, resulting in the control terminal being affected by electromagnetic waves, water, or humid gases.

[0038] The present utility model proposes a button structure that can solve the problem of poor electromagnetic wave shielding and water or moisture-proof gas effects of the existing button structures. The button structure is applied to the panel of the control terminal, and the panel is provided with installation holes for installing the button structure.

[0039] Please refer to Figure 1 、 Figure 2 , in an embodiment of the present utility model, the button structure includes:

[0040] The mounting base 100 is installed in the mounting hole and fixed to the panel 400. The mounting base 100 is formed with a shielding structure for shielding electromagnetic waves from passing through the mounting hole 410. Herein, there are many ways to fix the mounting base 100 to the panel 400, and no specific limitation is made here. After the mounting base 100 is installed in the mounting hole 410, the shielding structure can shield electromagnetic waves, preventing electromagnetic waves from passing through the mounting hole 410 and thus affecting the control terminal, so that the button structure of the present application has the function of preventing electromagnetic waves, further improving the performance of the present application.

[0041] The on-off member 200 is installed on the mounting base 100 and includes a reed 210 and a contact 220. When the reed 210 abuts against the contact 220, the reed 210 and the contact 220 can be connected. Specifically, conductive pins 230 are provided on both the reed 210 and the contact 220, and a connecting wire can be connected to the conductive pins 230. After the reed 210 and the contact 220 are connected, the current in the connecting wire can flow into the reed 210 through the conductive pin 230 on the reed 210, then enter the contact 220, and then flow out through the conductive pin 230 on the contact 220.

[0042] The waterproof rubber sleeve 300 is disposed outside the panel 400 and covers the mounting seat 100. When the mounting seat 100 is fixed to the panel 400, the waterproof rubber sleeve 300 is used to form a seal between the mounting seat 100 and the panel 400. The waterproof rubber sleeve 300 cooperates with the reed 210. Pressing the waterproof rubber sleeve 300 can push the reed 210 to move towards the contact 220 so that the reed 210 abuts against the contact 220. Specifically, the waterproof rubber sleeve 300 is arranged to cover the mounting seat 100. And when the mounting seat 100 is fixed to the waterproof panel 400, the waterproof rubber sleeve 300 makes a seal between the mounting seat 100 and the waterproof panel 400. Under the action of this sealing structure, water and humid gas cannot enter the control terminal through the mounting hole 410, thereby solving the technical problems existing in the prior art. Further, by pressing the waterproof rubber sleeve 300, the waterproof rubber sleeve 300 can push the reed 210 to move towards the contact 220 so that the reed 210 abuts against the contact 220. When the waterproof rubber sleeve 300 is released, the waterproof rubber sleeve 300 returns to its original state under its own elasticity, and the reed 210 leaves the contact 220 under its own elasticity and disconnects from the contact 220. Since the waterproof rubber sleeve 300 is arranged to cover the mounting seat 100, at this time, when the waterproof rubber sleeve 300 is pressed, water and humid gas also cannot enter the control terminal through the mounting hole 410. In this embodiment, the mounting seat 100 can be configured as a columnar structure with a hollow interior. One end covered by the waterproof rubber sleeve 300 is an opening, or one end covered by the waterproof rubber sleeve 300 is an opening and the other end is provided with a through hole for a connecting wire to pass through.

[0043] In one embodiment, referring to Figure 3 , Figure 4 , Figure 5, the shielding structure can be set as follows. A first flange 110 with an annular structure is provided outside the mounting base 100. The first flange 110 is located outside the panel 400, and the inner diameter of the mounting hole 410 is within the outer diameter of the first flange 110. A shielding hole 120 is provided inside the mounting base 100. The waterproof rubber sleeve 300 is provided with a trigger rod 330. The trigger rod 330 is arranged in the shielding hole 120. Pressing the waterproof rubber sleeve 300 can make the trigger rod 330 move within the shielding hole 120 and push the reed 210 towards the contact 220 to make the reed 210 abut against the contact 220. The mounting base 100 is configured with a metal material, and the metal material enables the mounting base 100 to form a shielding structure. In this embodiment, since the trigger rod 330 is provided in the waterproof rubber sleeve 300, at this time, when pressing the waterproof rubber sleeve 300, the pressing force can be transmitted to the reed 210 through the trigger rod 330. In this way, the reed 210 and the contact 220 can be arranged at a position far from the pressing position of the waterproof rubber sleeve 300, which is convenient for the installation of the reed 210 and the contact 220. Specifically, the trigger rod 330 is arranged in the shielding hole 120, and pressing the waterproof rubber sleeve 300 can make the trigger block move within the shielding hole 120. That is to say, the reed 210 and the contact 220 are located on one side of the shielding hole 120, and the pressing surface of the waterproof rubber sleeve 300 is arranged on the other side of the shielding hole 120. Specifically, the shielding hole 120 in this application is a micro-hole. There is no limit to the specific diameter of the shielding hole 120. The user can specifically set the diameter of the shielding hole 120 according to the wavelength to be shielded in the use environment, and the diameter of the shielding hole 120 needs to be smaller than the wavelength. At the same time, since the mounting base 100 is made of metal material, at this time, in this embodiment, the thickness of the first flange 110 needs to meet the thickness of electromagnetic shielding so that the mounting base 100 made of metal material can play the role of electromagnetic shielding. In this embodiment, the mounting base 100 can be configured as a columnar structure, and the inside is hollow. One end covered by the waterproof rubber sleeve 300 is an opening, or one end covered by the waterproof rubber sleeve 300 is an opening, and the other end is provided with a through hole for the connecting wire to pass through.

[0044] However, the present design is not limited to this. In other embodiments, the shielding structure can also be implemented in the following manner. Specifically, the waterproof rubber sleeve 300 is configured to be made of conductive silicone. Since the waterproof rubber sleeve 300 is located outside the panel 400, that is, outside the control terminal. At the same time, the waterproof rubber sleeve 300 is arranged to cover the mounting base 100, and the waterproof rubber sleeve 300 forms a seal between the mounting base 100 and the panel 400. In this way, the waterproof rubber sleeve 300 can achieve a sealing effect on the mounting holes 410 on the surface. At the same time, the material of the waterproof rubber sleeve 300 is configured to be conductive silicone, which can reflect and absorb electromagnetic waves under the action of the conductive silicone material to achieve a shielding effect. At the same time, the waterproof rubber sleeve 300 made of conductive silicone material also has environmental resistance and can be applied to harsh working environments.

[0045] In one embodiment, referring to Figure 3 、 Figure 4 、 Figure 5 , a threaded section 140 is provided outside the mounting base 100; the button structure further includes a nut 500. By cooperating with the threaded section 140, the nut 500, and the first flange 110, the mounting base 100 can be fixed to the panel 400. Specifically, when installing the case structure of the present application, the waterproof rubber sleeve 300 is wrapped around the mounting base 100, then the mounting base 100 is passed through the mounting hole 410 on the panel 400, and then the nut 500 is screwed onto the outside of the mounting base 100. By continuously rotating the nut 500, the first flange 110 on the mounting base 100 is moved towards the panel 400 until the first flange 110 abuts against the panel 400, thereby realizing the fixation of the mounting base 100 to the panel 400 through the cooperation of the threaded section, the nut 500, and the first flange 110. In this structure, the installation of the button structure can be facilitated. At the same time, by adopting the method of this embodiment, the production of the button structure can be facilitated and the cost is relatively low. However, the present design is not limited to this. In other embodiments, the mounting base 100 and the panel 400 can also be fixed to each other by means of a buckle. That is, a buckling position is provided outside the mounting base 100, and a buckle is provided on the panel 400. When the mounting base 100 is inserted through the mounting hole 410, when the first flange 110 abuts against the panel 400, at this time, the buckle is snapped into the buckling position to realize the fixation of the mounting base 100 to the panel 400.

[0046] In one embodiment, referring to Figure 3 、 Figure 4 、 Figure 5, the waterproof rubber sleeve 300 includes a sealing portion 310 and a movable portion 320 formed integrally. The trigger rod 330 is provided corresponding to the movable portion 320. The sealing portion 310 covers the first flange 110. When the mounting base 100 is fixed to the panel 400, the first flange 110 and the panel 400 press the sealing portion 310, and the sealing portion 310 forms a seal between the mounting base 100 and the panel 400. By pressing the movable portion 320, the trigger rod 330 can push the reed 210 to move towards the contact 220, so that the reed 210 abuts against the contact 220. In this embodiment, when the waterproof rubber sleeve 300 is configured as conductive silicone, the thickness of the first flange 110 may not be specifically limited. When the waterproof rubber sleeve 300 is ordinary silicone, the thickness of its first flange 110 needs to meet the thickness of electromagnetic shielding, so that the mounting base 100 made of metal can play the role of electromagnetic shielding. At the same time, when the nut 500, the threaded section and the first flange 110 cooperate to fix the mounting base 100 to the panel 400, the first flange 110 and the panel 400 can exert a squeezing effect on the sealing portion 310. As the distance between the panel 400 and the first flange 110 gets closer and closer, the squeezing force of the two on the sealing portion 310 will also be greater. At this time, the sealing effect between the two and the sealing portion 310 will be better. In this embodiment, when the mounting base 100 is fixed to the panel 400 by means of a buckle, when the first flange 110 reaches a preset position, the buckle is inserted into the buckle position, so as to realize fixing the mounting base 100 to the panel 400. At this time, the first flange 110 and the panel 400 can squeeze the sealing portion 310.

[0047] In one embodiment, the trigger rod 330 is integrally formed on the waterproof rubber sleeve 300. Specifically, the trigger rod 330 is integrally formed at the movable portion 320 of the waterproof rubber sleeve 300. In this way, the stability between the trigger rod 330 and the movable portion 320 can be better, making the waterproof rubber sleeve 300 more stable during the pressing process and avoiding the trigger rod 330 falling off from the movable portion 320. However, this design is not limited thereto. In other embodiments, the trigger rod 330 can be inserted into the waterproof rubber sleeve 300 or fixed to the waterproof rubber sleeve 300 by means of screw attachment.

[0048] In one embodiment, the sealing portion 310 is bonded to the first flange 110. In this embodiment, the sealing effect between the sealing portion 310 and the first flange 110 can also be achieved by bonding the sealing portion 310 to the first flange 110. In this way, when the mounting seat 100 is fixed on the panel 400, it can avoid excessive extrusion of the sealing portion 310 by the first flange 110 and the panel 400. At the same time, by bonding the sealing portion 310 to the first flange 110, when the movable portion 320 in the waterproof rubber sleeve 300 is pressed, the bonding portion between the sealing portion 310 and the first flange 110 is less affected, so that the bonding portion has better durability.

[0049] In one embodiment, referring to Figure 2 , Figure 3 , Figure 4 , the waterproof rubber sleeve 300 further includes an annular protrusion 311. The annular protrusion 311 is provided at one end of the sealing portion 310 in contact with the panel 400. In this embodiment, under the action of the annular protrusion 311, the thickness of the sealing portion 310 can be increased. At the same time, when the first flange 110 and the panel 400 squeeze the sealing portion 310, the annular protrusion 311 can deform first, so as to form a seal between the sealing portion 310 and the panel 400. Under the action of the annular protrusion 311, the sealing effect between the sealing portion 310 and the panel 400 can be improved. At the same time, when the sealing portion 310 is bonded to the first flange 110, the waterproof effect of the button structure of the present application can be better.

[0050] In one embodiment, referring to Figure 2 , Figure 3 , Figure 4 , the mounting seat 100 is provided with a mounting groove 130, and both the reed 210 and the contact 220 are arranged in the mounting groove 130. In this embodiment, by providing the mounting seat 100, the installation of the reed 210 and the contact 220 can be further facilitated, and at the same time, the length of the mounting seat 100 can be reduced, so that the required area of the mounting seat 100 in the control terminal is smaller, thereby achieving the purpose of further reducing the structure of the control terminal. In other embodiments, the reed 210 and the contact 220 can also be installed on the end face of the mounting seat 100.

[0051] In one embodiment, referring to Figure 2 , Figure 3 , Figure 4, the switching component further includes a plastic case 240. The reed 210 and the contact 220 are both installed in the plastic case 240. The plastic case 240 is fixed in the installation groove 130. The contact 220 and the plastic case 240 are integrally formed. By the way of integrally forming the contact 220 and the plastic case 240, it is convenient to produce the switching component. At the same time, the conductive pin 230 is installed in the plastic case 240. When the reed 210 and the contact 220 are not in contact under the action of the plastic case 240, it plays an insulating role. In this embodiment, the plastic case 240 is fixed in the installation groove 130 by bonding. In this way, the manufacturing cost of the button structure can be reduced. However, this design is not limited thereto. In other embodiments, the plastic case 240 can also be fixed in the installation groove 130 by inserting a pin through the plastic case 240 and the mounting base 100.

[0052] The present invention also provides a control terminal. Refer to Figure 1 , the control terminal includes a panel 400 and a button structure. The specific structure of the button structure refers to the above embodiments. Since this control terminal adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the panel 400 is provided with an installation hole 410, and the button structure is installed in the installation hole 410.

[0053] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the technical concept of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
