Description

Technical Field

[0001] This application relates to the technical field of capacitors, and in particular to a protective base capacitor. Background Technology

[0002] Capacitors have wide applications in power systems and electronic equipment, not only improving the power factor of circuits but also providing instantaneous current protection and other functions. With increasing demands for capacitor reliability and protection performance, designing structures that effectively protect capacitors while facilitating installation has become a research hotspot. Furthermore, to adapt to the needs of different application scenarios, capacitor designs are constantly being optimized, especially in improving protection performance and ease of assembly.

[0003] Utility model patent publication number CN213716722U discloses a capacitor with a connecting base device. The capacitor includes a capacitor housing and a base, with a connecting mechanism between the housing and the base. The connecting mechanism includes a locking element and an adjusting element. The locking element includes a protrusion, a pressing block, and a first spring. The protrusion is fixedly connected to the inner wall of the base, one end of the pressing block is fixedly connected to the outer wall of the capacitor housing, and one end of the first spring is fixedly connected to the outer wall of the capacitor housing, while the other end is fixedly connected to the outer wall of the pressing block. By setting up the connecting mechanism, a tight connection between the capacitor housing and the base is achieved through the abutment between the pressing block and the protrusion. Disassembly and reassembly of the capacitor housing and the base can be completed by pressing the moving block, reducing the time required for assembly and disassembly and increasing work efficiency. However, the above device only provides a fixing function and cannot protect the connection of the leads, resulting in poor applicability of the connecting base. Summary of the Invention

[0004] The purpose of this application is to provide a protective base capacitor to solve the problem that the capacitor's connection base cannot provide protection for the lead connection.

[0005] Firstly, the protective base capacitor provided in this application adopts the following technical solution:

[0006] A protective base capacitor includes:

[0007] The capacitor body is connected with leads and a sliding groove. The leads are located on the bottom surface of the capacitor body, and the sliding groove is located on the side surface of the capacitor body.

[0008] A protective cover is fitted onto the surface of the capacitor body. The protective cover is equipped with a sliding block that can slide within a sliding groove, so that the sliding block can move relative to the capacitor body along the axial direction.

[0009] The circuit board has a connection port and a mounting slot. The connection port corresponds to the lead wire and is used to connect the capacitor body and the circuit board. The mounting slot is located outside the connection port and corresponds to the protective cover. When the protective cover moves into the mounting slot, the protective cover surrounds the lead wire.

[0010] By adopting the above technical solution, the protective cover fitted onto the outside of the capacitor body can slide axially relative to the capacitor body via a sliding groove. When the leads and connectors are connected, the protective cover can move towards the leads, thus enclosing the leads and connectors within the annular protective cover. Furthermore, it connects to the circuit board via a mounting groove, protecting the connection between the leads and connectors from external interference and improving the stability of the installation connection. The connection between the protective cover and the circuit board not only protects the leads but also provides support and fixation for the capacitor, making the capacitor more stably fixed on the circuit board.

[0011] Optionally, the capacitor body is cylindrical, and the protective cover is annular.

[0012] By adopting the above technical solution, the cylindrical capacitor body can provide a more stable capacitance space for the capacitor, and the cylindrical structure is also easier to install, which helps to improve the applicability of the capacitor body.

[0013] Optionally, a bearing is provided between the sliding groove and the capacitor body to allow the protective cover to rotate relative to the capacitor body.

[0014] By adopting the above technical solution, the protective cover connects to the capacitor via a sliding groove. A bearing is provided between the sliding groove and the capacitor body, allowing the sliding groove to rotate relative to the capacitor body, thereby enabling the protective cover to rotate relative to the capacitor body. This rotatable protective cover allows for adjustment of the installation angle, thus improving the applicability of the installation.

[0015] Optionally, the edge of the protective cover away from the capacitor body has a first thread, and the mounting groove has a second thread, with the first thread engaging with the second thread.

[0016] By adopting the above technical solution, since the protective cover can rotate relative to the capacitor body, the first thread and the second thread enable the protective cover to connect with the mounting groove during rotation, thereby making the connection between the capacitor body and the circuit board tighter and improving the stability of the installation.

[0017] Optionally, a snap-fit ​​block is provided in the sliding groove, which can snap into the sliding groove to limit the axial sliding of the protective cover.

[0018] By adopting the above technical solution, the snap-fit ​​block can be snapped into the sliding block, thereby allowing the protective cover to slide off when not in use, facilitating the use of the capacitor body.

[0019] Optionally, the side wall of the capacitor body is also provided with a snap-fit ​​groove, and the protective cover is provided with a snap-fit ​​protrusion. The snap-fit ​​groove and the snap-fit ​​protrusion fit together to limit the rotation of the protective cover.

[0020] By adopting the above technical solution, the snap-fit ​​groove and snap-fit ​​protrusion can restrict the rotation of the protective cover. When the protective cover is not in the sliding state, it can prevent the protective cover from rotating relative to the capacitor body, thereby making the capacitor body easier to pick up and put down.

[0021] Optionally, a waterproof gasket is provided on the outside of the protective cover.

[0022] By adopting the above technical solution, the waterproof rubber ring is used to seal the space between the protective cover and the bottom of the mounting groove when the protective cover is connected to the mounting groove, so as to prevent liquid from entering and improve the protection of the lead wire.

[0023] Optionally, the outer side of the protective cover is provided with friction texture.

[0024] By adopting the above technical solution, the friction texture prevents slippage when the protective cover is rotated, thus improving the practicality of the capacitor.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. A sliding groove allows the protective cover, fitted onto the outside of the capacitor body, to slide axially relative to the capacitor body. When the leads and connectors are connected, the protective cover moves towards the leads, thus enclosing the leads and connectors within the ring-shaped cover. Furthermore, the cover connects to the circuit board via a mounting groove, protecting the connection between the leads and connectors from external interference and improving the stability of the installation connection. The connection between the protective cover and the circuit board not only protects the leads but also provides support and fixation for the capacitor, making the capacitor more stably mounted on the circuit board.

[0027] 2. Since the protective cover can rotate relative to the capacitor body, by providing the first thread and the second thread, the protective cover can form a connection with the mounting groove during rotation, thereby making the connection between the capacitor body and the circuit board tighter and improving the stability of the installation.

[0033] The following will provide a more detailed description of this application.

[0034] A protective base capacitor, reference Figure 1 and Figure 3 The system includes a capacitor body 1, a protective cover 2, and a circuit board 3. The capacitor body 1 has leads 11, a sliding groove 12, and a bearing 13 on its surface. The leads 11 are located on the bottom surface of the capacitor body 1 and are used to electrically connect the capacitor body 1 and the circuit board 3. The bearing 13 is sleeved on the outside of the capacitor body 1, and the sliding groove 12 is located on the outside of the bearing 13, allowing the sliding groove 12 to rotate relative to the capacitor body 1 via the bearing 13. The protective cover 2 is sleeved on the surface of the capacitor body 1, and a sliding block 21 is provided on the inner side of the protective cover 2. The sliding block 21 can slide within the sliding groove 12, allowing it to move relative to the capacitor body 1 along its axial direction and also rotate relative to the capacitor body 1. The capacitor body 1 has a cylindrical structure, and the protective cover 2 has a ring-shaped structure to facilitate sliding and rotation of the protective cover 2.

[0035] Reference Figure 3 and Figure 4A locking block 14 is provided at the upper part of the sliding groove 12. When the sliding block 21 moves above the locking block 14, the locking block 14 can lock with the sliding block 21, so that the locking block 14 cannot slide off the sliding groove 12 on its own. It is necessary to manually push the protective cover 2 downward to overcome the locking of the locking block 14 on the sliding block 21 and allow the protective cover 2 to move downward, thereby preventing the protective cover 2 from sliding off automatically, which is not conducive to the convenient use of the capacitor. The protective cover 2 is provided with a snap-fit ​​protrusion 23 on the side near the capacitor body 1. The side wall of the capacitor body 1 is provided with a snap-fit ​​groove 15. The snap-fit ​​groove 15 can fit with the snap-fit ​​protrusion 23 to restrict the rotation of the protective cover 2 when the snap-fit ​​block 14 is engaged with the sliding block 21. Thus, when the protective cover 2 is retracted, the protective cover 2 will not move in the axial direction due to the snap-fit ​​of the snap-fit ​​block 14, nor will it rotate due to the snap-fit ​​of the snap-fit ​​groove 15. Thus, the protective cover 2 will not move relative to the capacitor body 1 when retracted, making it more convenient to use and handle the capacitor body 1. When the protective cover 2 needs to be used, the protective cover 2 can be forcefully moved to release the snap-fit ​​between the snap-fit ​​block 14 and the sliding block 21. At the same time, the snap-fit ​​between the snap-fit ​​protrusion 23 and the snap-fit ​​groove 15 will also be released. Thus, the protective cover 2 can slide relative to the capacitor body 1 and rotate relative to the capacitor body 1, thereby connecting the circuit board 3 and surrounding the lead wire 11, protecting the lead wire 11 while maintaining the stability of the capacitor connection.

[0036] Reference Figure 2 and Figure 4 The circuit board 3 has a connection port 31 and a mounting groove 32. The connection port 31 corresponds to the lead wire 11 and is used to connect the capacitor body 1 and the circuit board 3. The mounting groove 32 is located outside the connection port 31 and corresponds to the protective cover 2. When the protective cover 2 moves into the mounting groove 32, the protective cover 2 surrounds the lead wire 11. In addition, the inner side of the outer edge of the protective cover 2 is provided with a first thread 22, and the inner edge of the mounting groove 32 is provided with a second thread 33. The first thread 22 and the second thread 33 are engaged. By rotating the protective cover 2, the first thread 22 can be connected to the second thread 33, thereby fixing the protective cover 2 in the mounting groove 32, stabilizing the connection between the protective cover 2 and the circuit board 3, protecting the connection between the capacitor body 1 and the circuit board 3 while stabilizing the fixation of the capacitor body 1 on the circuit board 3.

[0037] Reference Figure 4 The outer side of the protective cover 2 is also provided with a waterproof rubber ring 24. When the protective cover 2 is fixed in the mounting groove 32, the waterproof rubber ring 24 seals the edge of the protective cover 2 and the bottom surface of the mounting groove 32, thereby preventing liquid from entering the connection between the lead wire 11 and the connector 31 and protecting the stability of the connection. The outer side of the protective cover 2 is also provided with friction texture 25. The friction texture 25 can provide additional friction, making the protective cover 2 easier to be turned and rotated, improving the practicality of the capacitor.

[0038] The implementation principle of this embodiment is as follows: When the capacitor body 1 is not installed, the protective cover 2 is in a retracted state. The locking block 14 locks onto the sliding block 21, and the locking groove 15 and the locking protrusion 23 form a locking connection, preventing the protective cover 2 from moving relative to the capacitor body 1. When installing the capacitor, first connect the lead wire 11 and the connection port 31, then move the protective cover 2 to release the locking connection. By rotating the protective cover 2, the first thread 22 and the second thread 33 are connected to the mounting groove 32. At this time, the protective cover 2 surrounds the outside of the lead wire 11 and the connection port 31, providing protection for the connection between the lead wire 11 and the connection port 31.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
