Description

Technical Field

[0001] This utility model relates to the field of electronic device technology, and in particular to a capacitor insulating terminal cover. Background Technology

[0002] In the use of capacitors, it is generally necessary to install an insulating terminal cover, which usually consists of a cover body and terminals. Existing capacitor insulating terminal covers are prone to poor soldering and falling off.

[0003] The prior art CN204011077U discloses a capacitor insulating terminal cover, including a cover body, two quick-connect terminals, and two internal power lines. The quick-connect terminals include a connecting cylinder, a horizontal plate, and a vertical plate. The cover body has two mounting holes. The two quick-connect terminals are disposed on one side of the cover body and are respectively located in the two mounting holes. The two internal power lines are respectively disposed in the two quick-connect terminals. The connecting cylinder is fixedly connected to the internal power lines and is fixedly connected to the mounting holes. The horizontal plate is fixedly connected to one end of the connecting cylinder and has a lower connecting hole communicating with the connecting cylinder. The vertical plate is fixedly connected to the side of the horizontal plate away from the connecting cylinder and has an upper connecting hole. During manufacturing, due to its simple structure, the production cost is low, and the resistance is extremely low. Because the two internal power lines are respectively welded in the two connecting cylinders, the connection area with the quick-connect terminals is small, making it less likely for them to fall off or have poor soldering, thus improving the quality of the insulating terminal cover.

[0004] However, the capacitor insulation terminal cover of the above-mentioned existing technology does not have an isolation structure. In practical applications, electric arcs can easily form between the terminals, leading to capacitor damage. Utility Model Content

[0005] The purpose of this utility model is to provide a capacitor insulating terminal cover, which aims to solve the problem that the existing capacitor insulating terminal cover does not have an isolation structure, and in practical applications, arcing is easily formed between the terminals, leading to capacitor damage.

[0006] To achieve the above objectives, this utility model provides a capacitor insulating terminal cover, including a base plate, two quick-connect terminals, and an isolation mechanism. The isolation mechanism includes an insulating component, two mating components, a cap, an isolation plate, and a connecting component. The two quick-connect terminals are disposed above the base plate, the insulating component is disposed on the surface of the base plate, the two mating components are disposed above the insulating component, the cap is slidably connected to the top of the base plate, the isolation plate is fixedly connected to the cap and located between the two mating components, and the connecting component is disposed on the cap and the base plate.

[0007] The insulating assembly includes two insulating plates, an insulating sleeve, and two secondary insulating components. The two insulating plates are respectively fixedly connected to the upper and lower sides of the base plate. The insulating sleeve is fixedly connected to the two insulating plates and to the surface of the base plate. The two secondary insulating components are respectively disposed on the two insulating plates.

[0008] The secondary insulating component includes an insulating cylinder and a threading cylinder. The insulating cylinder is fixedly connected to the lower part of the lower insulating plate, and the threading cylinder is fixedly connected to the upper part of the upper insulating plate.

[0009] The mating assembly includes a mating strip and a mating frame. The mating strip is fixedly connected to the top of the insulating plate, and the mating frame is fixedly connected to the insulating plate and to one side of the mating strip.

[0010] The connecting assembly includes multiple connecting cylinders and multiple connecting posts. The multiple connecting cylinders are fixedly connected to the surface of the cap, and the multiple connecting posts are fixedly connected to the base plate and slidably connected within the multiple connecting posts.

[0011] This utility model discloses a capacitor insulating terminal cover. When using the capacitor, internal wires are soldered into two quick-connect terminals, and the insulating terminal cover is installed on the capacitor. External wires are passed through the insulating assembly and connected to the two quick-connect terminals. With the help of the connecting assembly, the cap is installed above the base plate. An isolation plate is positioned between two mating assemblies, working with the cap and the insulating assembly to separate the two quick-connect terminals. The two mating assemblies ensure a tighter connection between the cap and the base plate. The insulating assembly prevents current from damaging the capacitor or injuring the user. This design avoids the problem of existing capacitor insulating terminal covers lacking an isolation structure, which can easily lead to arcing between terminals and damage the capacitor in practical applications. This design effectively extends the capacitor's lifespan. Attached Figure Description

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] This utility model provides a capacitor insulating terminal cover: including a base plate 1, two quick-connect terminals 2, and an isolation mechanism. The isolation mechanism includes an insulating component 3, two mating components 4, a cap 5, an isolation plate 6, and a connecting component 7. The insulating component 3 includes two insulating plates 8, an insulating sleeve 9, and two secondary insulating components 10. The secondary insulating component 10 includes an insulating cylinder 11 and a wire threading cylinder 12. The mating component 4 includes a mating strip 13 and a mating frame 14. The connecting component 7 includes multiple connecting cylinders 15 and multiple connecting posts 16. The aforementioned solution solves the problem that existing capacitor insulating terminal covers do not have an isolation structure, and in practical applications, arcing easily forms between the terminals, leading to capacitor damage.

[0021] In this specific embodiment, two quick-connect terminals 2 are disposed above the base plate 1, the insulating component 3 is disposed on the surface of the base plate 1, two mating components 4 are disposed above the insulating component 3, the cap 5 is slidably connected to the top of the base plate 1, the isolation plate 6 is fixedly connected to the cap 5 and located between the two mating components 4, and the connecting component 7 is disposed on the cap 5 and the base plate 1. When using the capacitor, the internal wires are soldered into the two quick-connect terminals 2 respectively, and the insulating terminal cover is installed on the capacitor. After the external wires pass through the insulating component 3, they are connected to the two quick-connect terminals 2. With the help of the connecting component 7, the cap 5 is installed above the base plate 1. The isolation plate 6 is sandwiched between the two mating components 4, and together with the cap 5 and the insulating component 3, it separates the two quick-connect terminals 2. The two mating components 4 make the connection between the cap 5 and the base plate 1 tighter, and the insulating component 3 prevents the current from damaging the capacitor or injuring the user.

[0022] The two insulating plates 8 are fixedly connected to the upper and lower sides of the base plate 1, respectively. The insulating sleeve 9 is fixedly connected to the two insulating plates 8 and to the surface of the base plate 1. The two secondary insulating components 10 are respectively disposed on the two insulating plates 8. The two insulating plates 8 cover the upper and lower sides of the base plate 1, and the insulating sleeve 9 covers the four sides of the base plate 1. The secondary insulating components 10 are reserved with mounting holes for installing internal and external wires. When using the capacitor, only the two quick-connect terminals 2 can be energized, which can effectively improve the safety of the terminal cover.

[0023] Secondly, the insulating cylinder 11 is fixedly connected to the lower part of the insulating plate 8, and the wire threading cylinder 12 is fixedly connected to the upper part of the insulating plate 8. The insulating cylinder 11 covers the internal wires welded to the quick-connect terminal 2 to prevent current leakage and damage to the capacitor. The wire threading cylinder 12 is used to thread external wires, which facilitates the connection of external wires to the quick-connect terminal 2 while protecting the quick-connect terminal 2.

[0024] Meanwhile, the mating strip 13 is fixedly connected to the top of the insulating plate 8, and the mating frame 14 is fixedly connected to the insulating plate 8 and to one side of the mating strip 13. When the cap 5 is closed, the isolation plate 6 is inserted between the two mating strips 13, making the isolation plate 6 more stable, and the two mating frames 14 are close to the inner wall of the cap 5, making the connection between the cap 5 and the insulating plate 8 more tight.

[0025] Finally, multiple connecting cylinders 15 are fixedly connected to the surface of the cap 5, and multiple connecting posts 16 are fixedly connected to the base plate 1 and slidably connected within the multiple connecting posts 16. When the cap 5 is closed, the multiple connecting cylinders 15 are aligned with the multiple connecting posts 16 and the cap 5 is pressed down. The two mating frames 14 are inserted into the cap 5, the isolation plate 6 is inserted between the two mating strips 13, and the multiple connecting posts 16 are inserted into the multiple connecting cylinders 15 until the cap 5 and the insulating plate 8 are completely in close contact. With the cooperation of multiple components that rub against each other tightly, the cap 5 is firmly installed above the base plate 1, separating the two quick-connect terminals 2 so that no current can be generated between them.

[0026] When using the capacitor, the internal wires are soldered into the two quick-connect terminals 2, and the insulating terminal cover is installed on the capacitor. The external wires are then passed through the insulating assembly 3 and connected to the two quick-connect terminals 2. With the help of the connecting assembly 7, the cap 5 is installed above the base plate 1. The isolation plate 6 is positioned between the two mating assemblies 4, and together with the cap 5 and the insulating assembly 3, separates the two quick-connect terminals 2. The two mating assemblies 4 ensure a tighter connection between the cap 5 and the base plate 1. The insulating assembly 3 prevents current from damaging the capacitor or injuring the user. The two insulating plates 8 cover the top and bottom sides of the base plate 1, and the insulating sleeve 9 covers the perimeter of the base plate 1. The secondary insulating component 10 has pre-drilled holes for installing internal and external wires. When using the capacitor, only the two quick-connect terminals 2 can be energized, effectively improving the safety of the terminal cover. The insulating cylinder 11 covers the internal wires soldered to the quick-connect terminals 2, preventing current leakage and damage to the capacitor. The threading cylinder 12 is used to thread the external wires, facilitating... While protecting the quick-connect terminal 2, it allows external wires to connect to the quick-connect terminal 2. When the cap 5 is closed, the isolation plate 6 is inserted between the two mating strips 13, making the isolation plate 6 more stable. The two mating frames 14 are tightly attached to the inner wall of the cap 5, making the connection between the cap 5 and the insulating plate 8 tighter. When the cap 5 is closed, the multiple connecting cylinders 15 are aligned with the multiple connecting posts 16 and then the cap 5 is pressed down. The two mating frames 14 are inserted into the cap 5, the isolation plate 6 is inserted between the two mating strips 13, and the multiple connecting posts 16 are respectively inserted into the multiple connecting cylinders 15 until the cap 5 and the insulating plate 8 are completely tightly attached. With the cooperation of multiple parts that rub against each other tightly, the cap 5 is firmly installed above the base plate 1, separating the two quick-connect terminals 2, so that no current can be generated between them. This avoids the problem that the capacitor insulation terminal cover of the prior art does not have an isolation structure, and in practical applications, arcing is easily formed between the terminals, leading to capacitor damage. This achieves the effect of extending the service life of the capacitor.
