Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, specifically to a capacitor with adjustable lead length. Background Technology

[0002] In the field of electronic equipment, capacitors are commonly used components, widely applied in circuits for tuning, bypassing, coupling, and filtering. In practical applications, capacitors need to adapt to different installation environments and connect with electronic components at different depths. However, most existing capacitors have fixed-length leads, which makes it difficult to meet diverse connection requirements and limits their application in complex scenarios. There is an urgent need for a capacitor with adjustable lead length to solve this problem.

[0003] The lead lengths of existing capacitors are mostly fixed and cannot be adjusted according to requirements. The inflexible lead length makes it difficult to adapt to different installation scenarios and circuit connection requirements, resulting in poor versatility and inability to meet the needs of various working conditions. This makes it difficult to adjust flexibly when length adaptation is required, and may even affect the reliability of circuit contact due to the fixed length. Utility Model Content

[0004] The purpose of this invention is to provide a capacitor with adjustable pin length to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a capacitor with adjustable pin length, comprising a capacitor, a capacitor base fixedly connected to the bottom end of the capacitor, a pin adjustment mechanism provided on the surface of the capacitor base, and a spring contact mounting mechanism provided on the surface of the capacitor base.

[0006] The spring contact mounting mechanism includes a spring contact mounting base, and the pin adjustment mechanism includes an inner cylinder. The inner cylinder is mounted on the left and right ends of the bottom of the capacitor base. External threads are formed on the surface of the inner cylinder. A spring contact is mounted on the bottom end of the spring contact mounting base, and a pin is mounted on the bottom end of the spring contact. An outer cylinder is provided outside the inner cylinder, and internal threads are formed on the inner end of the outer cylinder. The inner and outer cylinders are threaded together via these threads. By rotating the outer cylinder, the outer cylinder can move up and down along the inner cylinder using the thread engagement, allowing adjustment to a suitable height. Pulling the pin then adjusts its length to adapt to different installation scenarios and circuit connection requirements. The length of the external thread is not less than the length of the outer cylinder, providing sufficient travel for the outer cylinder's movement and ensuring a large adjustment range for the pin. Simultaneously, limiting protrusions at both ends of the external thread prevent the outer cylinder from detaching from the inner cylinder during adjustment, ensuring the stability and safety of the adjustment mechanism. The extension of the length is achieved using the elasticity of the spring contact.

[0007] Preferably, the inner cylinder and the outer cylinder are connected together by external threads and internal threads, and the external threads and internal threads are matched with each other.

[0008] Preferably, the length of the external thread is not less than the length of the outer cylinder, and the two ends of the external thread are provided with limiting protrusions.

[0009] Preferably, the spring contact is made of beryllium copper strip and has a spiral structure.

[0010] Preferably, the spring contact mounting mechanism includes a spring contact mounting base, which is disposed at both ends of the bottom of the capacitor base. Mounting holes are provided at both ends of the bottom of the capacitor base. A first contact point is welded to the center of the top of the spring contact mounting base. First magnets are mounted at both ends of the top of the spring contact mounting base. A second contact point is welded to the center of the top of the mounting hole, and second magnets are mounted at both ends of the top of the mounting hole. The spring contact mounting mechanism achieves installation through the mutual attraction of the first and second magnets. The spring contact mounting base is quickly installed on the capacitor base, making the installation process simple and efficient. Simultaneously, the magnetic attraction ensures a stable connection of the mounting base, preventing loosening. The first and second contacts are electrically connected, ensuring smooth current transmission between the spring contact and the capacitor, reducing contact resistance, and ensuring normal capacitor operation. Furthermore, the spring contact, made of beryllium copper strip with a spiral structure, has good elasticity and conductivity, further improving the reliability and stability of the electrical contact.

[0011] Preferably, the first contact and the second contact are electrically connected, and the spring contact mounting base is disposed inside the mounting hole.

[0012] Compared with the prior art, this utility model provides a capacitor with adjustable lead length, which has the following advantages:

[0013] 1. This capacitor with adjustable pin length is equipped with a pin adjustment mechanism. The inner and outer cylinders are connected by external and internal threads. By rotating the outer cylinder, the engagement of the threads allows the outer cylinder to move up and down along the inner cylinder, adjusting to a suitable height as needed. Pulling the pin then adjusts its length to suit different installation scenarios and circuit connection requirements. The length of the external thread is not less than the length of the outer cylinder, providing sufficient travel for the outer cylinder's movement and ensuring a large adjustment range for the pin. Simultaneously, limiting protrusions at both ends of the external thread prevent the outer cylinder from detaching from the inner cylinder during adjustment, ensuring the stability and safety of the adjustment mechanism. The extension of the length is achieved using the elasticity of the spring contact.

[0014] 2. This capacitor with adjustable pin length features a spring contact mounting mechanism. The mechanism utilizes the attraction between a first and second magnet to achieve mounting, allowing for quick and easy installation of the spring contact mount onto the capacitor base. Simultaneously, the magnetic attraction ensures a secure connection, preventing loosening. The first and second contacts are electrically connected, guaranteeing unobstructed current flow between the spring contact and the capacitor, reducing contact resistance, and ensuring normal capacitor operation. Furthermore, the spring contact, made of beryllium copper strip with a spiral structure, possesses excellent elasticity and conductivity, further enhancing the reliability and stability of the electrical contact.

[0027] The spring contact mounting mechanism 4 includes a spring contact mounting base 41, and the pin adjustment mechanism 3 includes an inner cylinder 31. The inner cylinder 31 is mounted on the left and right ends of the bottom of the capacitor base 2. The surface of the inner cylinder 31 is provided with an external thread 32. A spring contact 33 is mounted on the bottom end of the spring contact mounting base 41, and a pin 34 is mounted on the bottom end of the spring contact 33. An outer cylinder 35 is provided outside the inner cylinder 31. An internal thread 36 is provided on the inner end of the outer cylinder 35. The inner cylinder 31 and the outer cylinder 35 are connected by the external thread 32 and the internal thread 36. By rotating the outer cylinder 35, the outer cylinder 35 can move up and down along the inner cylinder 31 using the meshing relationship of the threads. It can be adjusted to a suitable height as needed. At this time, pulling the pin 34 can adjust its length, so as to adapt to different installation scenarios and circuit connection requirements. The length of the external thread 32 is not less than the length of the outer cylinder 35, which can provide sufficient stroke for the movement of the outer cylinder 35 and ensure that the pin 34 has a large adjustment range. Meanwhile, the limiting protrusions at both ends of the external thread 32 can prevent the outer cylinder 35 from falling off the inner cylinder 31 during the adjustment process, ensuring the stability and safety of the adjustment mechanism, and using the elasticity of the spring contact piece 33 to achieve the extension of length.

[0028] The inner cylinder 31 and the outer cylinder 35 are connected together by external thread 32 and internal thread 36, and the external thread 32 and internal thread 36 are matched with each other.

[0032] Please see Figure 1-5 Furthermore, based on Embodiment 1, the spring contact mounting mechanism 4 further includes a spring contact mounting base 41, which is disposed at the left and right ends of the bottom of the capacitor base 2. Mounting holes 44 are provided at both ends of the bottom of the capacitor base 2. A first contact point 42 is welded to the center of the top of the spring contact mounting base 41. A first magnet 43 is installed at the left and right ends of the top of the spring contact mounting base 41. A second contact point 45 is welded to the center of the top inside the mounting hole 44. A second magnet 46 is installed at the left and right ends of the top inside the mounting hole 44. The spring contact mounting mechanism 4 achieves installation by the mutual attraction of the first magnet 43 and the second magnet 46. The spring contact mounting base 41 is quickly installed on the capacitor base 2, and the installation process is simple and efficient. Meanwhile, the attraction of the magnet ensures that the mounting base is firmly connected and not easily loosened. The first contact 42 and the second contact 45 are electrically connected. This design ensures that the current transmission between the spring contact 33 and the capacitor 1 is smooth, reduces contact resistance, and ensures the normal operation of the capacitor 1. In addition, the spring contact 33, which is made of beryllium copper strip and has a spiral structure, has good elasticity and conductivity, further improving the reliability and stability of the electrical contact.
