[0019]This invention features a sliding support column that slides inside the pressing block. A buffer plate at the bottom directly contacts the workpiece, forming an elastic buffer chain with a buffer spring. When the pressing handle is pressed down, the sliding support column pushes the buffer plate against the workpiece, and the buffer spring is simultaneously compressed to absorb the impact energy. This ensures sufficient pressure to complete the welding while avoiding surface damage caused by contact with hard materials. The two sliding support columns and their corresponding buffer springs are symmetrically distributed around the pressing block, achieving bidirectional balanced force application and significantly improving the uniformity of pressure distribution.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic capacitor warping welding technology, and in particular to a safety-compliant ceramic capacitor warping welding structure. Background Technology
[0002] Safety-certified ceramic capacitors are capacitors that simultaneously meet safety certification and ceramic dielectric characteristics. They are mainly used for electromagnetic interference filtering and safety isolation, and are widely used in power input circuits. Dielectric characteristics: Made of ceramic materials (such as X7R, Y5U, etc.), they feature good high-frequency performance, high temperature resistance (up to 125°C), and non-polarity. X capacitors (bridging live and neutral wires): Voltage ratings include X1 (>2.5kV), X2 (≤2.5kV), etc., with larger capacitance values but requiring a parallel safety resistor. Y capacitors (bridging ground wires): Available in Y1 (≥8kV), Y2 (≥5kV) ratings, with smaller capacitance values to limit leakage current. They are mainly used in high-frequency interference suppression circuits in power adapters, household appliances (such as televisions and air conditioners), and industrial equipment switching power supplies to ensure safe equipment operation. Priority should be given to brands that have passed safety certification, matching the safety level (e.g., Y1 level is preferred for medical equipment) and voltage / capacitance parameters.
[0003] An existing safety-certified ceramic capacitor has a warped welding structure that can easily cause the product to warp during the welding process when workers are using welding equipment. This can affect the stability of the equipment during welding and the quality of the weld. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a safety-certified ceramic capacitor warping welding structure.
[0005] This utility model is achieved by the following technical solution: a safety-certified ceramic capacitor warping welding structure, including a pressing support block, a fixing sleeve fixedly connected to the top of the pressing support block, and a pressing handle fixedly connected to the top of the fixing sleeve;
[0006] The pressing block is internally slidably connected to a sliding support column. A buffer rubber plate is fixedly connected to the bottom of the sliding support column. Auxiliary support plates are fixedly connected to both ends of the buffer rubber plate. A buffer spring is fixedly connected to the top of the buffer rubber plate. A fixed upright plate is fixedly connected to the top of the pressing block. A transverse spring is fixedly connected to the right end of the fixed upright plate. A rotating collar is fixedly connected to the right end of the transverse spring. A limit plate is rotatably connected to the right end of the rotating collar.
[0007] Through the above technical solution, the pressing support block serves as the core load-bearing body, and the fixed sleeve at its top provides vertical guidance for the pressing handle, ensuring that the operating force is transmitted along the axial direction.
[0008] As a further improvement to the above solution, the number of the sliding support and the buffer rubber plate is set to two, and the two sliding support and the buffer rubber plate are symmetrically distributed front and back with the pressing support block as the center.
[0009] Through the above technical solution, the auxiliary support plates fixed at the left and right ends of the buffer rubber plate constitute an auxiliary support system. The four auxiliary support plates are symmetrically distributed on the left and right sides with the pressing support block as the center, forming a stable structure that is enclosed on all four sides.
[0010] As a further improvement to the above scheme, the number of auxiliary support plates is set to four, and two of them are grouped together. The four auxiliary support plates are symmetrically distributed on the left and right sides with the pressing support block as the center.
[0011] Through the above technical solution, the linkage between the auxiliary support plate and the buffer rubber plate transforms the concentrated pressure into surface contact, reduces the pressure per unit area, and avoids component breakage caused by excessive local stress.
[0012] As a further improvement to the above solution, the buffer rubber plate is located at the bottom of the pressing support block, the auxiliary support plate is located at the bottom of the pressing support block, and the buffer spring is fixedly connected to the bottom of the pressing support block.
[0013] Through the above technical solution, the horizontal spring at the right end of the fixed plate, together with the rotating collar and the limiting plate, forms an adaptive reset system. When the squeeze handle is released, the horizontal spring pushes the rotating collar to cause the limiting plate to rebound, thereby driving the sliding support and buffer plate to automatically reset.
[0014] As a further improvement to the above solution, the squeeze handle is located at the top of the pressing block, the fixing sleeve is located on the front of the fixing plate, and the limiting plate is located at the right end of the transverse spring.
[0015] As a further improvement to the above solution, the rotating collar is located at the right end of the fixed plate, the limiting plate is located at the right end of the fixed plate, and the transverse spring is located at the left end of the limiting plate.
[0016] As a further improvement to the above solution, the transverse spring is located at the right end of the fixed sleeve, and the number of buffer springs is set to two, with the two buffer springs symmetrically distributed front and back around the pressing support block.
[0017] As a further improvement to the above solution, the limiting plate is located at the right end of the pressing block, and the rotating collar is located at the right end of the pressing block.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] This invention features a sliding support column that slides inside the pressing block. A buffer plate at the bottom directly contacts the workpiece, forming an elastic buffer chain with a buffer spring. When the pressing handle is pressed down, the sliding support column pushes the buffer plate against the workpiece, and the buffer spring is simultaneously compressed to absorb the impact energy. This ensures sufficient pressure to complete the welding while avoiding surface damage caused by contact with hard materials. The two sliding support columns and their corresponding buffer springs are symmetrically distributed around the pressing block, achieving bidirectional balanced force application and significantly improving the uniformity of pressure distribution.
[0020] This utility model uses a horizontal spring on the right end of the fixed upright plate, a rotating collar, and a limiting plate to form an adaptive reset system. When the squeeze handle is released, the horizontal spring pushes the rotating collar to cause the limiting plate to rebound, driving the sliding support and buffer plate to automatically reset. By setting a fixed sleeve to wrap around the squeeze handle, it not only prevents the handle from slipping out of the hand during operation, but also avoids the risk of fingers accidentally touching moving parts.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0028] Example:
[0029] Please combine Figure 1-4 The safety-certified ceramic capacitor warping welding structure of this embodiment includes a pressing support block 1, a fixing sleeve 2 fixedly connected to the top of the pressing support block 1, and a pressing handle 3 fixedly connected to the top of the fixing sleeve 2.
[0030] The pressing block 1 has a sliding support column 4 internally connected. The bottom of the sliding support column 4 is fixedly connected to a buffer rubber plate 5. The left and right ends of the buffer rubber plate 5 are fixedly connected to auxiliary support plates 6. The top of the buffer rubber plate 5 is fixedly connected to a buffer spring 7. The top of the pressing block 1 is fixedly connected to a fixed upright plate 8. The right end of the fixed upright plate 8 is fixedly connected to a transverse spring 9. The right end of the transverse spring 9 is fixedly connected to a rotating collar 10. The right end of the rotating collar 10 is rotatably connected to a limit plate 11. By setting the sliding support column 4 internally connected to the pressing block 1, the buffer rubber plate 5 at the bottom directly contacts the workpiece and forms an elastic buffer chain with the buffer spring 7. When the pressing handle 3 is pressed down, the sliding support column 4 pushes the buffer rubber plate 5 against the workpiece, and the buffer spring 7 is simultaneously compressed to absorb the impact energy. This ensures sufficient pressure to complete the welding and avoids surface damage caused by contact with hard materials. The two sliding support columns 4 and the corresponding buffer springs 7 are symmetrically distributed back and forth with the pressing block 1 as the center, realizing bidirectional balanced force application and significantly improving the uniformity of pressure distribution.
[0031] The pressing block 1 serves as the core support, and the fixed sleeve 2 at its top provides vertical guidance for the pressing handle 3, ensuring that the operating force is transmitted along the axial direction.
[0032] The number of sliding support pillars 4 and buffer rubber plates 5 is set to two, and the two sliding support pillars 4 and buffer rubber plates 5 are symmetrically distributed front and back with the pressing support block 1 as the center.
[0033] The auxiliary support plates 6 fixed at both ends of the buffer rubber plate 5 constitute an auxiliary support system. The four auxiliary support plates 6 are symmetrically distributed on the left and right sides with the pressing support block 1 as the center, forming a stable structure that is enclosed on all four sides.
[0034] The number of auxiliary support plates 6 is set to four, and each pair is a group of two. The four auxiliary support plates 6 are symmetrically distributed on the left and right sides with the pressing support block 1 as the center.
[0035] The linkage between the auxiliary support plate 6 and the buffer rubber plate 5 transforms concentrated pressure into surface contact, reducing the pressure per unit area and preventing component breakage caused by excessive local stress.
[0036] The buffer rubber plate 5 is located at the bottom of the pressing support block 1, the auxiliary support plate 6 is located at the bottom of the pressing support block 1, and the buffer spring 7 is fixedly connected to the bottom of the pressing support block 1. By setting the transverse spring 9 at the right end of the fixed upright plate 8, the rotating collar 10, and the limiting plate 11 to form an adaptive reset system, when the squeezing handle 3 is released, the transverse spring 9 pushes the rotating collar 10 to drive the limiting plate 11 to rebound, driving the sliding support 4 and the buffer rubber plate 5 to automatically reset. By setting the fixed sleeve 2 to wrap around the squeezing handle 3, it not only prevents the handle from slipping out of the hand during operation, but also avoids the risk of fingers accidentally touching the moving parts.
[0037] The horizontal spring 9 at the right end of the fixed upright plate 8, together with the rotating collar 10 and the limiting plate 11, forms an adaptive reset system. When the squeeze handle 3 is released, the horizontal spring 9 pushes the rotating collar 10 to cause the limiting plate 11 to rebound, thereby driving the sliding support column 4 and the buffer rubber plate 5 to automatically reset.
[0038] The squeeze handle 3 is located on top of the pressing support block 1, the fixing sleeve 2 is located on the front of the fixing plate 8, and the limiting plate 11 is located at the right end of the transverse spring 9.
[0039] The rotating collar 10 is located at the right end of the fixed upright plate 8, the limiting plate 11 is located at the right end of the fixed upright plate 8, and the transverse spring 9 is located at the left end of the limiting plate 11.
[0040] The transverse spring 9 is located at the right end of the fixed sleeve 2, and the number of buffer springs 7 is set to two, which are symmetrically distributed back and forth with the pressing support block 1 as the center.
[0041] The limiting plate 11 is located at the right end of the pressing support block 1, and the rotating collar 10 is located at the right end of the pressing support block 1.
[0042] The implementation principle of the safety-certified ceramic capacitor warping welding structure in this application embodiment is as follows: A sliding support column 4 is slidably connected inside the pressing support block 1. The buffer rubber plate 5 at the bottom directly contacts the workpiece and forms an elastic buffer chain with the buffer spring 7. When the pressing handle 3 is pressed down, the sliding support column 4 pushes the buffer rubber plate 5 against the workpiece, and the buffer spring 7 is compressed simultaneously to absorb the impact energy. This ensures sufficient pressure to complete the welding and avoids surface damage caused by contact with hard materials. The two sliding supports 4 and the corresponding buffer springs 7 are symmetrically distributed front and back with the pressing support block 1 as the center, realizing bidirectional balanced force application and significantly improving the uniformity of pressure distribution. An adaptive reset system is formed by setting a transverse spring 9 at the right end of the fixed upright plate 8, a rotating collar 10, and a limiting plate 11. When the pressing handle 3 is released, the transverse spring 9 pushes the rotating collar 10 to drive the limiting plate 11 to rebound, driving the sliding support column 4 and the buffer rubber plate 5 to automatically reset. By setting a fixed sleeve 2 to wrap around the pressing handle 3, the handle is prevented from slipping out during operation, and the risk of accidental finger contact with moving parts is avoided.
