[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 In order to solve the problem that the existing connection method of low-noise ceramic capacitors is generally to directly solder the pins to the reserved soldering points of the circuit board through a soldering agent, this connection method may have the phenomenon of unreliable soldering, thereby affecting the stability and reliability of the capacitor, and even adversely affecting the performance of the entire circuit board, the following preferred technical solutions are provided:

[0022] A stable connection structure of a low-noise ceramic capacitor comprises a ceramic substrate 1, a chip is installed in the inner cavity of the ceramic substrate 1, two groups of pin bodies 2 are installed at the lower end of the ceramic substrate 1, movable grooves 3 are opened on the outer walls of both sides of the ceramic substrate 1, and a connecting component 4 is installed on the inner wall of the movable groove 3. The connecting component 4 comprises a first connecting plate 41 and a second connecting plate 42 which are respectively slidably connected to the inner walls of the movable grooves 3 on both sides of the ceramic substrate 1, the lower ends of the first connecting plate 41 and the second connecting plate 42 are fixedly connected with connecting columns 43, the lower ends of the connecting columns 43 are connected with connecting reinforcement plates 44, and threaded holes are reserved on the connecting reinforcement plates 44 for connecting screws.

[0023] An annular groove 45 is formed on the upper wall of the connecting reinforcement plate 44 , and the connecting column 43 is slidably connected to the inner wall of the annular groove 45 . The first connecting plate 41 and the second connecting plate 42 are symmetrically distributed about the center of the ceramic substrate 1 .

[0024] A sliding channel 46 is provided on the inner wall of the movable groove 3, and a movable block 47 is slidably connected to the inner wall of the sliding channel 46, one end of the movable block 47 is fixedly connected to the first connecting plate 41 and the second connecting plate 42, and a receiving groove 48 is provided inside the movable block 47, and an inner connecting rod 49 is slidably connected to the inner wall of the receiving groove 48, and a support spring 410 is sleeved on the outer wall of the inner connecting rod 49, and the lower end of the inner connecting rod 49 is fixedly connected to the bottom plate of the cavity of the sliding channel 46, one end of the support spring 410 is fixedly connected to the movable block 47, and the other end thereof is fixedly connected to the bottom plate of the cavity of the sliding channel 46.

[0025] Specifically, when installing the capacitor, the two groups of pin bodies 2 are welded to the reserved welding points of the circuit board through a soldering agent, and then the first connecting plate 41 and the second connecting plate 42 are pulled down, and the first connecting plate 41 and the second connecting plate 42 are used to drive the connecting reinforcement plate 44 to fit on the circuit board through the connecting column 43, and the screws are used to reinforce the connection between the capacitor and the circuit board through the reserved threaded holes to ensure a stable connection, which solves the problem of the existing connection method of low-noise ceramic capacitors. Generally, the pins are directly welded to the reserved welding points of the circuit board through a soldering agent. This connection method may have the phenomenon of unreliable welding, thereby affecting the stability and reliability of the capacitor, and even causing adverse effects on the performance of the entire circuit board. Through the cooperation of the connecting column 43 and the annular groove 45, the connecting reinforcement plate 44 can be rotated to adjust the position of the connecting reinforcement plate 44, which provides convenience for installation.

[0026] After pulling down the first connecting plate 41 and the second connecting plate 42, the movable block 47 will be driven to move downward on the inner wall of the sliding channel 46, and the inner connecting rod 49 will be received by the receiving groove 48, thereby compressing the support spring 410. The support spring 410 exerts a reaction force on the movable block 47, so that the movable block 47 drives the first connecting plate 41 and the second connecting plate 42 to pull up the connecting reinforcement plate 44. At this time, the connecting reinforcement plate 44 and the circuit board are fixed, and only an upward pulling force can be formed. Therefore, after disassembly, the first connecting plate 41 and the second connecting plate 42 will drive the connecting reinforcement plate 44 to quickly reset, and the operation is convenient.

[0027] In summary: when installing the capacitor, the two groups of pin bodies 2 are welded to the reserved welding points of the circuit board through the soldering agent, and then the first connecting plate 41 and the second connecting plate 42 are pulled down, and the first connecting plate 41 and the second connecting plate 42 are used to drive the connection reinforcement plate 44 to fit on the circuit board through the connecting column 43, and the screws are used to reinforce the connection between the capacitor and the circuit board through the reserved threaded holes to ensure a stable connection. The connection reinforcement plate 44 can be rotated through the cooperation of the connecting column 43 and the annular groove 45, and the position of the connection reinforcement plate 44 can be adjusted to facilitate installation. After pulling the first connecting plate 41 and the second connecting plate 42, the movable block 47 will be driven to move downward on the inner wall of the sliding channel 46, and the inner connecting rod 49 will be received by the receiving groove 48, thereby compressing the support spring 410. The support spring 410 exerts a reaction force on the movable block 47, so that the movable block 47 drives the first connecting plate 41 and the second connecting plate 42 to pull up the connecting reinforcement plate 44. At this time, the connecting reinforcement plate 44 and the circuit board are fixed, and only an upward pulling force can be formed. Therefore, after disassembly, the first connecting plate 41 and the second connecting plate 42 will drive the connecting reinforcement plate 44 to quickly reset.
