Description

Technical Field

[0001] This utility model relates to the technical field of high-voltage connectors, and in particular to a connecting terminal for a high-voltage connector. Background Technology

[0002] A high-voltage connector is an electrical component used to connect high-voltage cables or wires to enable the transmission and distribution of high-voltage power in a high-voltage power system. The connector terminals are the core components that enable electrical connections in a high-voltage connector. They are usually made of metal materials with good conductivity and may be plated with gold, tin, or other treatments to enhance corrosion resistance and conductivity. Their core function is to transmit power or signals through a stable contact interface, while also having sufficient mechanical strength to withstand complex working conditions such as vibration and impact.

[0003] A high-voltage connector terminal device, disclosed on the Chinese Patent Network (publication number CN211017651U), includes a body, a connection port, a connecting post, a cover, a sealing ring, a socket, an insulating layer, a connection terminal, a connection protrusion, a connection slot, a conductive post, a conductive layer, and threads. The body has a connection port at one end, and the threads are arranged on the connection port. The connecting post is installed inside the connection port and connects to components inside the body. A sealing ring is arranged at the bottom of the cover, and the socket is located on the sealing ring. This invention has multiple connection ports for connecting different components. When not in use, the cover is threaded onto the connection port to seal it, enhancing safety and protecting the connecting post. The connection terminal is threaded to the connecting post for easy disassembly. The outer surface of the connection terminal is made of insulating material to prevent danger, and the internal conductive copper post ensures stable power supply. This device is suitable for widespread use.

[0004] The following problems exist with this solution: the sealing cap is installed separately on the outside of the connection port, which can easily lead to its loss. Also, the lack of a limiting mechanism when the connection terminal is inserted into the inside of the connection port makes it prone to detachment, resulting in low practicality and certain drawbacks.

[0005] Therefore, in order to solve the above problems, this utility model provides a connection terminal for a high-voltage connector. Utility Model Content

[0006] The purpose of this invention is to provide a connection terminal for a high-voltage connector to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a connecting terminal for a high-voltage connector, comprising a high-voltage connector body, a plurality of connecting ports evenly spaced on one side of the outer surface of the high-voltage connector body, a connecting post installed on the inner side wall of the connecting port, a sealing cover provided on the outside of the connecting port, a protective pad installed on one side of the sealing cover and on the connecting post, an adjusting component provided on the outside of the high-voltage connector body and on the protective pad, a connecting terminal provided on the connecting port, a connecting slot opened on the inner side of the connecting terminal, a limiting ring installed on the outer ring surface of the connecting terminal, and a limiting component provided on the outside of the high-voltage connector body and outside the limiting ring.

[0008] Preferably, the outer ring surface size of the connection port is adapted to the inner side wall size of the sealing cap, and when the sealing cap is located outside the connection port, the protective pad is located exactly outside the connecting post.

[0009] Preferably, the adjustment assembly includes a fixed frame mounted on the high-voltage connector body and located on both sides of the connection port, a slide rod installed on the top and bottom of the inner side of the fixed frame, and a slider installed on the outer ring surface of the slide rod and located inside the fixed frame.

[0010] Preferably, a support frame is installed on the outer side of the slider, a movable rod is installed on the inner side wall of the support frame, a first return spring is installed on the outer ring surface of the movable rod, one end of the movable rod is connected to the outer side of the sealing cover away from the protective pad, and a first handle is installed after the end of the movable rod away from the sealing cover passes through the support frame.

[0011] Preferably, guide rods are installed on the outside of the sealing cover and on both sides of the movable rod. One end of the guide rod passes through the support frame and extends to its outside. The outer ring surface of the guide rod is slidably connected to the inside of the support frame.

[0012] Preferably, the limiting component includes a fixing plate installed outside the high-voltage connector body and above the connection port, a guide post installed at the bottom of the fixing plate, a second reset spring installed on the outer ring surface of the guide post, a second handle installed at the top end of the guide post after passing through the fixing plate, and a wedge installed at the bottom end of the guide post.

[0013] Preferably, when the sealing cap is located outside the connection port, the inclined block is tightly attached to the outside of the sealing cap, and when the connection terminal is located on the connection port, the inclined block is tightly attached to the limiting ring outside it.

[0014] In summary, this utility model has the following beneficial technical effects: This high-voltage connector terminal features a mechanism where, when the sealing cover needs to be opened, pulling the first handle moves the movable rod outward on the support frame. This compresses the first return spring, and the movement of the movable rod causes the sealing cover to move away from the connection port, thus opening the cover. When the sealing cover is away from the connection port, the support frame can be moved downward along the sliding rod via a slider, allowing the sealing cover to move below the connection port for easy installation of the terminal. By lifting the second handle, the guide post moves upward under the force of the second return spring, causing the inclined block to rise. After installing the terminal or sealing cover outside the connection port, releasing the second handle causes the inclined block at the bottom of the guide post to move downward under the reset action of the second return spring, contacting the limiting ring or sealing cover on the terminal and preventing its movement. This design offers convenient operation and superior practicality. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1 - Figure 6 The present invention will be described in further detail below.

[0018] A connecting terminal for a high-voltage connector, as shown in the reference. Figure 1 - Figure 6The connector includes a high-voltage connector body 1. Several connection ports 2 are evenly spaced on one side of the outer surface of the high-voltage connector body 1. A connecting post 3 is installed on the inner side wall of the connection port 2. A sealing cover 4 is provided on the outside of the connection port 2. A protective pad 5 is installed on the outer side of the sealing cover 4 and on the connecting post 3. An adjustment component 6 is provided on the outside of the high-voltage connector body 1 and on the protective pad 5. A connection terminal 7 is provided on the connection port 2. A connection slot 701 is opened on the inner side of the connection terminal 7. A limit ring 8 is installed on the outer ring surface of the connection terminal 7. A limit component 9 is provided on the outside of the high-voltage connector body 1 and on the outside of the limit ring 8.

[0019] Reference Figure 1 - Figure 6 The outer ring size of the connection port 2 is matched with the inner wall size of the sealing cover 4. When the sealing cover 4 is located outside the connection port 2, the protective pad 5 is located outside the connecting post 3. Since the outer ring size of the connection port 2 is matched with the inner wall size of the sealing cover 4, the sealing cover 4 can be tightly fitted to the outside of the connection port 2 to play a good sealing and protection role. When the sealing cover 4 is correctly installed on the connection port 2, the protective pad 5 just covers the outside of the connecting post 3, further enhancing the protection of the connecting post 3 and preventing dust, moisture and other substances from entering the interior of the connection port 2 and affecting the connection performance.

[0020] Reference Figure 4 - Figure 6The adjustment assembly 6 includes a fixed frame 10 mounted on the high-voltage connector body 1 and located on both sides of the connection port 2. A slide rod 11 is mounted on the top and bottom inner side of the fixed frame 10. A slider 12 is mounted on the outer ring surface of the slide rod 11, located inside the fixed frame 10. The fixed frame 10 provides a stable mounting base for the adjustment assembly 6, and, fixed to the high-voltage connector body 1 and located on both sides of the connection port 2, provides support and positioning. The slide rod 11, mounted between the top and bottom inner side of the fixed frame 10, provides a sliding track for the slider 12, allowing the slider 12 to slide freely on the slide rod 11. A support frame 13 is installed on the outer side of the sliders 12. A movable rod 14 is installed on the inner side wall of the support frame 13. A first return spring 15 is installed on the outer ring surface of the movable rod 14. One end of the movable rod 14 is connected to the outer side of the sealing cover 4 away from the protective pad 5. The end of the movable rod 14 away from the sealing cover 4 passes through the support frame 13 and is fitted with a first handle 16. The support frame 13 is connected between the sliders 12 and moves with the sliders 12, while providing an installation position for the movable rod 14. When it is necessary to open the sealing cover 4, the first handle 16 is pulled. 16 drives the movable rod 14 to move outward on the support frame 13. At this time, the first return spring 15 is compressed. The movement of the movable rod 14 causes the sealing cover 4 to move away from the connection port 2, thus opening the sealing cover 4. When the first handle 16 is released, the first return spring 15, due to its own elastic restoring force, will push the movable rod 14 to move inward. The movable rod 14 drives the sealing cover 4 back to the outside of the connection port 2, resealing. When the sealing cover 4 moves away from the connection port 2, the support frame 13 can be moved downward along the slide rod 11 via the slider 12, so that the sealing cover 4 can be moved below the connection port 2 for easy access. Install the connection terminal 7. Guide rods 17 are installed on both sides of the sealing cover 4 and on the outside of the movable rod 14. One end of the guide rod 17 passes through the support frame 13 and extends to its outside. The outer ring surface of the guide rod 17 is slidably connected to the inside of the support frame 13. When the sealing cover 4 moves under the drive of the movable rod 14, the guide rod 17 will slide inside the support frame 13. The guide rod 17 plays the role of restricting the movement direction of the sealing cover 4, ensuring that the sealing cover 4 can only move in a straight line along the axial direction of the guide rod 17, and preventing the sealing cover 4 from deviating or shaking during the movement.

[0021] Reference Figure 1 - Figure 5The limiting assembly 9 includes a fixing plate 18 mounted on the outside of the high-voltage connector body 1 and located above the connection port 2. A guide post 19 is mounted on the bottom of the fixing plate 18, and a second return spring 20 is mounted on the outer ring surface of the guide post 19. A second handle 21 is mounted on the top end of the guide post 19 after passing through the fixing plate 18, and a wedge 22 is mounted on the bottom end of the guide post 19. By lifting the second handle 21, the elastic force of the second return spring 20 causes the guide post 19 to move upward, driving the wedge 22 to rise. After the connection terminal 7 or the sealing cover 4 is installed outside the connection port 2, the second handle 21 is released. Under the reset action of the second return spring 20, the wedge 22 at the bottom of the guide post 19 also moves downward, contacting the limiting ring 8 or the sealing cover 4 on the connection terminal 7 and generating a limiting effect to prevent it from moving downward. When the sealing cover 4 is located outside the connection port 2, the inclined block 22 is tightly attached to the outside of the sealing cover 4. When the connection terminal 7 is located on the connection port 2, the inclined block 22 is tightly attached to the limiting ring 8 outside it. When the sealing cover 4 is outside the connection port 2, the inclined block 22 is tightly attached to the outside of the sealing cover 4 under the action of the second return spring 20. The interaction between the inclined block 22 and the outside of the sealing cover 4 generates a force on the sealing cover 4 in the direction of the connection port 2 to prevent the sealing cover 4 from moving accidentally and to ensure the sealing state of the connection port 2. When the connection terminal 7 is inserted into the connection port 2, the inclined block 22 is also tightly attached to the limiting ring 8 outside the connection terminal 7 under the action of the second return spring 20. Through the interaction between the inclined block 22 and the limiting ring 8, a limiting force is generated on the connection terminal 7 to prevent the connection terminal 7 from accidentally falling off due to vibration or other reasons during use.

[0022] The implementation principle of a high-voltage connector terminal according to this utility model embodiment is as follows: When using this device, since the outer ring size of the connection port 2 is adapted to the inner wall size of the sealing cover 4, the sealing cover 4 can be tightly fitted on the outside of the connection port 2 to achieve good sealing and protection. When the sealing cover 4 is correctly installed on the connection port 2, the protective pad 5 just covers the outside of the connecting post 3, further enhancing the protection of the connecting post 3 and preventing dust, moisture, etc. from entering the connection port 2 and affecting the connection performance. The fixed frame 10 provides a stable installation base for the adjustment component 6, is fixed on the high-voltage connector body 1 and located on both sides of the connection port 2, and plays a supporting and positioning role. The slide rod 11 is installed between the top and bottom of the inner side of the fixed frame 10 to provide a sliding track for the slider 12. The slider 12 can slide freely on the slide rod 11. The support frame 13 is connected between the sliders 12 and moves with the movement of the sliders 12. At the same time, it provides an installation position for the movable rod 14. When it is necessary to open the seal... When the cover 4 is pulled, the first handle 16 is pulled, and the first handle 16 drives the movable rod 14 to move outward on the support frame 13. At this time, the first return spring 15 is compressed. The movement of the movable rod 14 drives the sealing cover 4 away from the connection port 2 to open the sealing cover 4. When the first handle 16 is released, the first return spring 15 will push the movable rod 14 inward due to its own elastic restoring force. The movable rod 14 drives the sealing cover 4 back to the outside of the connection port 2 to re-seal. When the sealing cover 4 is away from the connection port 2, the support frame 13 can be moved downward along the slide rod 11 through the slider 12, so that the sealing cover 4 can be moved below the connection port 2 for easy installation of the connection terminal 7. When the sealing cover 4 moves under the drive of the movable rod 14, the guide rod 17 will slide inside the support frame 13. The guide rod 17 plays the role of limiting the movement direction of the sealing cover 4, ensuring that the sealing cover 4 can only move in a straight line along the axial direction of the guide rod 17, and preventing the sealing cover 4 from deviating or shaking during the movement. By lifting the second handle 21, the elastic force of the second return spring 20 causes the guide post 19 to move upward, driving the inclined block 22 to rise. After the connecting terminal 7 or the sealing cover 4 is installed outside the connection port 2, the second handle 21 is released. Under the reset action of the second return spring 20, the inclined block 22 at the bottom of the guide post 19 also moves downward, contacting the limiting ring 8 on the connecting terminal 7 or the sealing cover 4 and generating a limiting effect to prevent its movement. When the sealing cover 4 is outside the connection port 2, the inclined block 22 is pressed tightly against the outside of the sealing cover 4 under the action of the second return spring 20. The interaction between the inclined block 22 and the outside of the sealing cover 4 generates a force on the sealing cover 4 in the direction of the connection port 2 to prevent the sealing cover 4 from moving accidentally and to ensure the sealing state of the connection port 2. When the connecting terminal 7 is inserted into the connection port 2, the inclined block 22 is also pressed tightly against the limiting ring 8 outside the connecting terminal 7 under the action of the second return spring 20. Through the interaction between the inclined block 22 and the limiting ring 8, a limiting force is generated on the connecting terminal 7 to prevent the connecting terminal 7 from accidentally falling off due to vibration or other reasons during use, thus improving its practicality.
