Description

Technical Field

[0001] This utility model relates to the field of connector terminal technology, and in particular to a dustproof structure for inductor connector terminal assemblies. Background Technology

[0002] In modern electronic devices, inductors are key components in circuits, and the stability and reliability of their performance are of paramount importance. Connecting terminals are electrical components used to connect wires or other electrical components so that the circuit can function properly.

[0003] During the use of connector terminals, traditional connection methods such as plug-in connections are prone to loosening during frequent plugging and unplugging, leading to unstable connections. In addition, traditional designs lack effective dustproof sealing and mechanisms to prevent wires from falling off, resulting in unstable connections and affecting the stability and reliability of inductor connection lines.

[0004] Therefore, to address the aforementioned issues of inconvenience in achieving dustproof sealing and secure connection of the wire terminals, a dustproof structure for the inductor connection terminal assembly can be designed. During use, the sealing cover fits tightly against the inner wall of the socket, and the lower end of the locking rod slides down along the frustum surface into the locking hole for engagement. This achieves dustproof sealing and secure connection of the wire terminals, effectively improving the reliability and service life of the inductor connection terminal assembly. Utility Model Content

[0005] In order to overcome the problem that the traditional design of the connector terminal lacks an effective dustproof sealing mechanism during use, which allows dust and impurities to enter the connector terminal, it is necessary to improve the design and make it difficult to achieve dustproof sealing and stable connection of the terminal. This not only affects the stability of the connecting wire, but may also lead to the degradation of the inductor performance.

[0006] The technical solution of this utility model is as follows: a dustproof structure for an inductor connection terminal assembly, including a wire terminal, a cavity, a socket, a plug, a connecting wire, a socket, a plug, a frustum, a frustum groove, a guide frame, a locking rod, a limit ring, a return spring, a locking hole, and a sealing cover. The wire terminal has a cavity inside, and two sets of sockets are formed through the front side wall of the wire terminal. Two sets of plugs are arranged inside the cavity. Two sets of connecting wires are arranged at the front end of the wire terminal. A socket is fixedly arranged at the front end of the connecting wires, and a plug is fixedly arranged at the front end of the socket. A frustum is arranged on the front side wall of the socket. A frustum groove is formed on the inner wall of the front end of the plug. A guide frame is fixedly arranged at the top of the inner wall of the cavity. A locking rod is arranged inside the guide frame. A limit ring is fixedly arranged on the side wall of the locking rod. A return spring is fixedly arranged at the upper end of the limit ring. A locking hole is formed on the side wall of the frustum. Two sets of sealing covers are arranged inside the cavity.

[0007] Preferably, when the connecting wire terminal is in use and not in use, the sealing cover is tightly fitted to the inner wall of the socket, thereby closing the front side wall of the wire terminal and effectively preventing dust from entering the cavity, ensuring the dustproof and sealing performance of the cavity. When the connecting wire is plugged into the wire terminal, firstly, the socket and plug at the front end of the connecting wire are inserted into the socket. During this process, the front end of the plug abuts and presses against the end face of the sealing cover. As the plug continues to go deeper, the sealing cover flips into the cavity, and then the plug is tightly engaged with the inside of the socket. At this time, the frustum-shaped surface of the front side wall of the socket is tightly engaged with the frustum-shaped groove of the front inner wall of the socket. During the process of close contact, the top of the frustum surface abuts and presses against the lower end of the locking rod. As the socket continues to penetrate deeper, the elasticity of the return spring allows the lower end of the locking rod to slide down along the frustum surface into the locking hole for engagement, thus locking the socket and connecting wires in a locked state. This effectively prevents the wires from falling off. When the connecting wires are disassembled from the terminal blocks, the process is reversed. In summary, the dustproof structure of this inductor connection terminal assembly, through ingenious component design and combination, achieves dustproof sealing and a stable connection effect for the wire ends, effectively improving the reliability and service life of the inductor connection terminal assembly.

[0008] Preferably, the locking rod is slidably connected to the guide frame, the upper end of the locking rod is slidably connected to the top of the wire end terminal, and the lower end of the locking rod is slidably connected to the top of the insert.

[0009] Preferably, the plug and the socket are engaged, the upper end of the return spring is fixedly connected to the bottom wall of the guide frame, and the lower end of the locking rod is engaged with the inside of the locking hole.

[0010] Preferably, the inner wall of the rear end of the socket is provided with an annular groove, and the front side wall of the wire terminal is fixedly provided with a positioning ring, and the annular groove and the positioning ring are engaged and connected.

[0011] Preferably, multiple sets of mounting blocks are fixedly installed on the inner wall of the cavity, and a mounting shaft is rotatably installed between two sets of mounting blocks. The mounting blocks have mounting holes inside.

[0012] Preferably, two sets of hinge springs are provided on the side walls at both ends of the mounting shaft. One end of the hinge spring is fixedly connected to the side wall at one end of the mounting shaft, and the other end of the hinge spring is fixedly connected to the inner wall of the mounting hole.

[0013] Preferably, a connector is fixedly provided at the top left end of the sealing cover, and the left end of the connector is fixedly connected to the side wall of the mounting shaft. The sealing cover is rotatably connected to the mounting block through the mounting shaft.

[0014] The beneficial effects of this utility model are:

[0015] When the connecting wire terminal is in use, in the non-use state, the sealing cover fits tightly against the inner wall of the socket, thus closing the front side wall of the wire terminal and effectively preventing dust from entering the cavity, ensuring the dustproof and sealing performance of the cavity. When the connecting wire is inserted into the wire terminal, firstly, insert the socket and plug at the front end of the connecting wire into the socket. During this process, the front end of the plug abuts and presses against the end face of the sealing cover. As the plug continues to go deeper, the sealing cover flips into the cavity, and then the plug tightly engages with the inside of the socket. At this time, the frustum-shaped surface of the front side wall of the socket fits tightly against the frustum-shaped groove on the front inner wall of the socket. During this process, the top of the frustum surface comes into contact with and is pressed against the lower end of the locking rod. As the socket continues to penetrate deeper, the elasticity of the return spring allows the lower end of the locking rod to slide down along the frustum surface into the locking hole for engagement, thus locking the socket and connecting wires in a locked state. This effectively prevents the wires from falling off. When the connecting wires are to be disassembled from the terminal block, the process is reversed. In summary, the dustproof structure of this inductor connection terminal assembly, through clever component design and combination, achieves dustproof sealing and a stable connection effect for the wire ends, effectively improving the reliability and service life of the inductor connection terminal assembly.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 and Figure 3 This utility model provides an embodiment of a dustproof structure for an inductor connection terminal assembly, including a wire terminal 1, a cavity 2, a socket 3, a plug 4, a connecting wire 5, a socket 6, a plug 7, a frustum 8, a frustum groove 9, a guide frame 10, a locking rod 11, a limiting ring 12, a return spring 13, a locking hole 14, and a sealing cover plate 15. The wire terminal 1 has a cavity 2 inside, and two sets of sockets 3 are provided through the front side wall of the wire terminal 1. Two sets of plugs 4 are provided inside the cavity 2, and two sets of connecting wires 4 are provided at the front end of the wire terminal 1. A socket 6 is fixedly installed at the front end of the wire 5, a plug 7 is fixedly installed at the front end of the socket 6, a frustum 8 is provided on the front side wall of the socket 6, a frustum groove 9 is opened on the front inner wall of the insert 4, a guide frame 10 is fixedly installed at the top of the inner wall of the cavity 2, a locking rod 11 is provided inside the guide frame 10, a limit ring 12 is fixedly installed on the side wall of the locking rod 11, a return spring 13 is fixedly installed at the upper end of the limit ring 12, a locking hole 14 is opened on the side wall of the frustum 8, and two sets of sealing cover plates 15 are provided inside the cavity 2.

[0025] Please see Figure 2 and Figure 4The locking rod 11 is slidably connected to the guide frame 10. The upper end of the locking rod 11 is slidably connected to the top of the wire terminal 1, and the lower end of the locking rod 11 is slidably connected to the top of the insert 4. Pulling the upper end of the locking rod 11 upwards causes its lower end to disengage from the locking hole 14, thereby unlocking the front end of the connecting wire 5. The plug 7 is engaged with the insert 4. The upper end of the return spring 13 is fixedly connected to the bottom wall of the guide frame 10, and the lower end of the locking rod 11 is engaged with the inside of the locking hole 14. Under the elastic action of the return spring 13, the wire 5 can be unlocked. The lower end of the locking rod 11 slides down along the frustum 8 into the locking hole 14 and engages, thereby locking the socket 6 and the connecting wire 5. The inner wall of the rear end of the socket 6 is provided with an annular groove 16, and the front side wall of the wire terminal 1 is fixedly provided with a positioning ring 17. The annular groove 16 and the positioning ring 17 engage and connect. When the connecting wire 5 and the wire terminal 1 are inserted, the annular groove 16 on the inner wall of the rear end of the socket 6 engages tightly with the positioning ring 17 on the front side wall of the wire terminal 1, thereby improving the dustproof sealing and stable connection effect of the overall structure.

[0026] Please see Figure 5 and Figure 6 Multiple sets of mounting blocks 18 are fixedly installed on the inner wall of cavity 2. A mounting shaft 19 is rotatably connected between two sets of mounting blocks 18. Mounting holes 20 are opened inside the mounting blocks 18. The mounting shaft 19 can be adjusted to rotate through the mounting blocks 18. Two sets of hinge springs 21 are provided on the side walls of both ends of the mounting shaft 19. One end of the hinge spring 21 is fixedly connected to one side wall of the mounting shaft 19, and the other end of the hinge spring 21 is fixedly connected to the inner wall of the mounting hole 20. Under the elastic action of the hinge spring 21, the sealing cover 15 can be rotated and reset to the inside of the insertion hole 3 through the mounting shaft 19, so that the front side wall of the wire terminal 1 is closed. A connector 22 is fixedly installed on the top left end of the sealing cover 15. The left end of the connector 22 is fixedly connected to the side wall of the mounting shaft 19. The sealing cover 15 is rotatably connected to the mounting blocks 18 through the mounting shaft 19. The mounting shaft 19 can be adjusted to rotate through the connector 22.

[0027] When the connecting wire terminal is in use, in the non-use state, the sealing cover 15 is tightly fitted to the inner wall of the socket 3. The elastic action of the hinge spring 21 ensures that the sealing cover 15 remains inside the socket 3, thereby closing the front side wall of the wire terminal 1. This effectively prevents dust from entering the cavity 2, ensuring the dustproof and sealing performance of the cavity 2.

[0028] When the connecting wire 5 is plugged into the wire terminal 1, firstly, the socket 6 and plug 7 at the front end of the connecting wire 5 are inserted inward into the socket 3. During this process, the front end of the plug 7 comes into contact with and is pressed against the end face of the sealing cover 15. As the plug 7 continues to go deeper, the sealing cover 15 rotates around the mounting shaft 19 via the connector 22, causing it to flip into the cavity 2.

[0029] Subsequently, the plug 7 engages tightly with the interior of the socket 4. At this time, the frustum 8 on the front side wall of the socket 6 fits tightly with the frustum groove 9 on the front inner wall of the socket 4. During this process, the top of the frustum 8 presses against the lower end of the locking rod 11. As the socket 6 continues to penetrate, under the elastic action of the return spring 13, the lower end of the locking rod 11 slides down along the frustum 8 into the locking hole 14 and engages, thus locking the socket 6 and the connecting wire 5. This effectively prevents the wire from falling off. At the same time, when the connecting wire 5 is plugged into the terminal 1, the annular groove 16 on the rear inner wall of the socket 6 engages tightly with the positioning ring 17 on the front side wall of the terminal 1. This improves the dustproof sealing and stable connection of the overall structure.

[0030] When disconnecting the connecting wire 5 from the terminal 1, firstly, pull the upper end of the locking rod 11 upwards, causing its lower end to disengage from the locking hole 14, thus unlocking the front end of the connecting wire 5. Then, pull the connecting wire 5 outwards, allowing its front plug 7 to disengage from the socket 4. When the plug 7 disengages from the socket 3, the hinge spring 21, under the elastic action, drives the connecting piece 22 and the sealing cover 15 to rotate and return to the socket 3 via the mounting shaft 19, causing the front side wall of the terminal 1 to close, ensuring the dustproof sealing performance of the cavity 2.

[0031] In summary, the dustproof structure of this inductor connection terminal assembly, through ingenious component design and combination, achieves dustproof sealing and a stable connection effect on the wire ends, effectively improving the reliability and service life of the inductor connection terminal assembly.

[0032] Through the above steps, when the connecting wire terminal is in use, in the non-use state, the sealing cover 15 is tightly fitted to the inner wall of the socket 3, thereby forming a closed state at the front side wall of the wire terminal 1, effectively preventing dust from entering the cavity 2 and ensuring the dustproof sealing performance of the cavity 2. When the connecting wire 5 is plugged into the wire terminal 1, firstly, the socket 6 and plug 7 at the front end of the connecting wire 5 are inserted into the socket 3. During this process, the front end of the plug 7 abuts and is pressed against the end face of the sealing cover 15. As the plug 7 continues to penetrate, the sealing cover 15 flips into the cavity 2. Subsequently, the plug 7 is tightly engaged with the inside of the socket 4. At this time, the frustum 8 of the front side wall of the socket 6 is engaged with the inner wall of the front end of the socket 4. The truncated cone groove 9 achieves a tight fit. During this process, the top of the truncated cone surface 8 abuts and presses against the lower end of the locking rod 11. As the socket 6 continues to penetrate deeper, under the elastic action of the return spring 13, the lower end of the locking rod 11 can slide down along the truncated cone surface 8 into the locking hole 14 for engagement, thereby locking the socket 6 and the connecting wire 5, effectively preventing the wire from falling off. When the connecting wire 5 is disassembled from the wire terminal 1, the operation is reversed as described above. In summary, the dustproof structure of this inductor connection terminal assembly, through ingenious component design and combination, achieves dustproof sealing and stable connection of the wire end, effectively improving the reliability and service life of the inductor connection terminal assembly.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
