[0046] The following describes various embodiments of the embodiments of the present application with reference to the accompanying drawings. These embodiments are merely exemplary and not a limitation on the embodiments of the present application.
[0047] The embodiments of the present application provide a button component.
[0048] Figure 1 is a schematic diagram of the button component of the embodiments of the present application.
[0049] As Figure 1 shown, the button component 1 includes a first button part 2 and a second button part 3.
[0050] Figure 2 is another schematic diagram of the button component of the embodiments of the present application, showing the situation observed from one side of the first button part; Figure 3 is still another schematic diagram of the button component of the embodiments of the present application, showing the situation of cutting the button component along the Figure 2 shown AA direction.
[0051] As Figure 2 and Figure 3 shown, the first button part 2 is formed with a through hole 4, and the second button part 3 is provided with a clamping protrusion 5, and the clamping protrusion 5 penetrates through the through hole 4.
[0052] As can be seen from the above embodiments, the convex 5 provided on the second button part 3 penetrates through the through hole 4 formed in the first button part 2. Thus, the cable of the medium and low frequency physiotherapy device can be welded to the convex 5 passing through the through hole 4 and directly connected to the second button part, which can improve the reliability of electrical connection. Moreover, there is no need for soldering operation between the first button component and the second button component, which can reduce costs.
[0053] For example, in the existing female snap structure, the cable is welded to the first surface of the first button part, and the second surface of the first button part and the second button part are soldered for electrical connection, thereby realizing the electrical connection between the cable and the second button part. However, in such a structure, there is a problem that the contact between the first button part and the second button part is poor due to the falling off of the solder or the poor soldering process. In the embodiments of the present application, there is no need for the soldering process between the first button part and the second button part, which can reduce the material and process costs, and the cable is directly welded to the second button part, which can ensure reliable electrical connection between the two.
[0054] In one or more embodiments, the part of the convex protruding from the through hole can be formed as a welding part. Thus, it is beneficial for welding with the cable and enables the cable to be directly connected to the second button part. In the embodiments of the present application, there is no limitation on the specific shape of the welding part. For example, the welding part can be a shape with a larger cross-section relative to the convex main body, or the part of the convex protruding from the through hole can be bent to form the welding part, etc. As long as it is beneficial for welding the part of the convex protruding from the through hole.
[0055] In one or more embodiments, at least a part of the convex abuts against the inner peripheral surface of the through hole. Thus, the first button part and the second button part can be reliably connected through the abutment between the convex and the through hole, further improving the reliability of electrical connection.
[0056] In the embodiments of the present application, there is no limitation on the specific shapes of the convex and the through hole. For example, as Figure 2 shown, when observing from the opening side of the through hole 4, the opening of the through hole 4 is rectangular, and the convex 5 is arc-shaped. Thus, a fixed connection between the convex and the through hole can be achieved, thereby ensuring a reliable connection between the first button part and the second button part.
[0057] However, the present application is not limited thereto. The convex and the through hole can also be other structures that can achieve the abutment between the two. For example, when the opening of the through hole is rectangular, the convex can be circular, such as an ellipse or a standard circle, or the convex can be a polygon inscribed in the inner peripheral surface of the through hole.
[0058] However, the present application is not limited thereto. For example, Figure 4 shows another schematic diagram of the button component of the embodiments of the present application. As Figure 4As shown, when observing from the opening side of the through-hole, the opening of the through-hole 4a is arc-shaped and the clamping projection 5a is rectangular. However, the present application is not limited thereto. For example, the opening of the through-hole can be circular and the clamping projection can be polygonal.
[0059] In one or more embodiments, as Figure 3 shown, the opening of the through-hole 4 near the second button part 3 has a guiding part 6. Thus, the clamping projection 5 can be smoothly inserted into the through-hole 4.
[0060] In the embodiments of the present application, there is no limitation on the specific implementation manner of the guiding part 6. For example, the guiding part can be an arc surface or an inclined surface formed on at least a part of the opening. Thus, the clamping projection 5 can be smoothly inserted into the through-hole 4.
[0061] Figure 5 is Figure 3 an enlarged schematic view of a partial P in
[0062] As Figure 5 shown, in one or more embodiments, the guiding part 6 can be an arc surface S formed on one side surface of the opening. For example, when the opening is rectangular, the guiding part 6 can be formed on one side of the rectangular opening; when the opening is circular, the guiding part can be formed on a part of the circle. The present application is not limited thereto.
[0063] As Figure 5 shown, by forming the guiding part 6, the opening of the through-hole near the second button part has a larger inner diameter in the part away from the first button part 2. That is to say, the closer to the second button part, the larger the inner diameter. As Figure 5 shown, the inner diameter dimension D of the part near the second button part 3 is greater than the inner diameter dimension d of the part away from the second button part 3. Thus, it is convenient for the clamping projection to be inserted into the through-hole.
[0064] As Figure 3 described, in one or more embodiments, the clamping projection 5 is arranged on the edge of the second button part 3. However, the present application is not limited thereto. For example, the clamping projection can be arranged at any position of the second button part 3 as long as it can penetrate and be inserted into the through-hole formed in the first button part.
[0065] In one or more embodiments, the clamping projection and the second button part can be an integrally formed structure. For example, after the second button part is formed, a part of the edge of the second button part can be bent to form the clamping projection, or during the integral forming process, the clamping projection protrudes from the second button part. However, the present application is not limited thereto. The clamping projection and the second button part can also be separately formed and then the clamping projection is fixed to the second button part.
[0066] In the embodiments of the present application, there is no limitation on the number of through-holes. For example, Figures 2 to 3The number of through holes is shown as 1, but the present application is not limited thereto. The number of through holes can also be 2 or more than 2. For example, the first button part can form a plurality of closely arranged through holes, and the clamping protrusion is in the shape of a plurality of protrusions at the end corresponding to the number of through holes. In this way, the clamping protrusion and the through holes are formed in a shape where the plurality of protrusions are inserted into the plurality of through holes, which can improve the connection reliability between the two.
[0067] In one or more embodiments, the first button part and the second button part are riveted in a non-rotatable manner. Thereby, during the manufacturing and / or use process, the mutual rotation of the first button part and the second button part can be suppressed, and thus the connection reliability can be further improved.
[0068] In one or more embodiments, the shape of the riveting part of the second button part can be a non-circular shape, for example, an asymmetric shape. Thereby, the first button part and the second button part can be riveted in a non-rotatable manner. However, the present application is not limited thereto. For example, the shape of the riveting part of the second button can be a rectangle or a polygon. In this way, after riveting, the first button part and the second button part will not rotate relative to each other.
[0069] As Figure 3 shown, in one or more embodiments, the button component 1 further includes a spring part 7. The spring part 7 is disposed inside the second button part 3, and the spring part 7 locks the plug head inserted into the button component. Thereby, a reliable electrical connection between the plug head and the button component can be achieved.
[0070] For example, the button component in the embodiment of the present application can be used as a female snap button, and cooperate with a plug head as a male head to form a complete conductive button. When the plug head is inserted into the button component, the plug head can be locked by the spring part 7, so that the button component and the plug head are in contact and conduct electricity.
[0071] Next, an exemplary description of the manufacturing process of the button component 1 is given. First, the spring portion 7 is pressed into the second button portion 3, and the edge of the second button portion 3 is bent to form a clamping protrusion. Then, a riveting operation is performed on the first button portion 2 and the third button portion. For example, the central protrusion of the first button portion 2 is inserted into the center of the second button portion, and at the same time, the clamping protrusion of the second button portion is clamped into the through hole of the first button portion. Next, the central protrusion of the first button portion 2 is extruded using, for example, a stamping machine to form a riveted state between the first button portion 2 and the second button portion 3. After that, a cable or wire harness is welded at the through hole of the first button portion 2. For example, the clamping protrusion protrudes from the through hole, and the cable or wire harness is fully welded to the exposed portion. Or, the clamping protrusion may not protrude from the through hole. In this case, a welding portion is formed at the end of the clamping protrusion located in the through hole close to the first button portion 2, so that the cable or wire harness is directly electrically connected to the second button portion 3. Finally, the button component after the wire harness welding is placed in a mold for injection molding. Due to the mutual cooperation between the clamping protrusion and the through hole, the second button portion has been welded to the wire harness, and there will be no problems of loosening or poor conduction in the formed button component.
[0072] An embodiment of the present application further provides a medium and low frequency physiotherapy instrument, including: an electrode sheet; a plug head provided on the electrode sheet; the button component as described above, and the plug head is inserted into the button component from the side of the second button portion; a cable, one end of which is welded to the clamping protrusion, for example, the welding portion formed at the end of the clamping protrusion; and a power plug head connected to the other end of the cable. Regarding the button component, reference can be made to the above description of the button component 1, and details will not be repeated here.
[0073] Thus, in such a medium and low frequency physiotherapy instrument, the power supply can be directly electrically connected to the second button portion through the cable, and the second button portion is electrically connected to the electrode sheet by connecting with the plug head, thereby realizing power supply to the electrode sheet. Therefore, the electrical connection reliability can be improved, and there is no need for soldering operation between the first button component and the second button component, which can reduce costs.
[0074] In the embodiment of the present application, the button component can also be applied to other devices or occasions, such as an electrocardiograph, or can be used on a quick plug connector that requires conductivity, or can be used on a conductive button that requires injection molding. The present application does not limit this.
[0075] It should be noted that the above Figures 1 to 5 only gives a schematic description of the button component and the medium and low frequency physiotherapy instrument of the embodiment of the present application, but the present application is not limited thereto. The specific content of each structure or component can also refer to the related technology; in addition, structures or components not shown Figures 1 to 5 can be added, or Figures 1 to 5 one or more structures or components in Figures 1 to 5For components or elements not specifically specified herein, reference may be made to related technologies, and the present application does not limit this.

However, those skilled in the art should clearly understand that these descriptions are exemplary and do not limit the protection scope of the embodiments of the present application. Those skilled in the art can make various variations and modifications to the embodiments of the present application according to the spirit and principle of the embodiments of the present application, and these variations and modifications are also within the scope of the embodiments of the present application.

Therefore, the appended claims are intended to cover all such features and advantages of these implementation manners that fall within their true spirit and scope.
