[0001] This utility model relates to the field of voltage regulator technology, and in particular to a terminal block mounting structure and a voltage regulator. Background Technology

[0002] A voltage regulator is a device that can automatically adjust the output voltage. Its main function is to stabilize the power supply voltage, which is fluctuating or does not meet the requirements of electrical equipment, within a set range, so that various circuits or electrical equipment can work normally under the rated operating voltage.

[0003] In the prior art, an L-shaped cover plate is set on the voltage regulator housing, and the wiring terminals are placed on the cover plate. When the cover plate is opened, wiring can be performed from the opening. However, the wiring terminals are not fixed, and the position of the wiring terminals needs to be specially adjusted to complete the wiring operation. Moreover, the wiring has no fixed force point, which makes it easy to loosen and is not conducive to secure wiring.

[0004] In other words, the existing wiring terminals are not fixed, which means that the position of the wiring terminals needs to be specially adjusted when wiring, which is inconvenient. In addition, there is no fixed force point, which makes them prone to loosening and is not conducive to secure wiring. Summary of the Invention

[0005] The purpose of this utility model is to provide a terminal block mounting structure and a voltage regulator to support and fix the terminal block, make the terminal block setting angle convenient for wiring operations, provide a fixed force point for wiring, improve the wiring firmness, and reduce the possibility of wiring loosening.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides a terminal block mounting structure, including a main housing, a cover plate, and a mounting bracket. The main housing has a wiring through hole and an operating port. The mounting bracket is fixed to the main housing and is used to fix the wiring terminals of a voltage regulator, with the first wiring port of the wiring terminal facing the wiring through hole. The cover plate is connected to the main housing and can selectively close the operating port, which provides operating space for screwing the wiring terminal.

[0008] As an optional technical solution for the terminal block mounting structure, the mounting bracket has a bearing ramp that extends downward at an inclination toward the wiring through hole. The bearing ramp is used to support the terminal block and to position the screw of the terminal block toward the operating port.

[0009] As an optional technical solution for the terminal block mounting structure, the screws of the terminal block include a wiring screw and an internal screw, which are arranged side by side with intervals. The internal screw is located on the side of the wiring screw away from the operating port. The bearing inclined surface forms a preset angle with the horizontal plane, and the operating port is set with a preset shape so that only the wiring screw can be operated and tightened from the operating port.

[0010] As an optional technical solution for the terminal block mounting structure, both the wiring through hole and the operating port are provided on the side of the main housing, and the mounting bracket is fixed to the bottom surface of the main housing;

[0011] The mounting bracket has a positioning boss on the side near the main housing, which is used to fit against the side of the main housing.

[0012] As an optional technical solution for terminal block mounting structure, the mounting bracket is welded to the main housing.

[0013] As an optional technical solution for the terminal block mounting structure, it also includes fasteners. The mounting bracket includes a bearing portion and two support portions. The bearing portion is connected to the two support portions at both ends. The bearing portion is used to fix the terminal block. The support portions are detachably fixed to the main housing by the fasteners.

[0014] As an optional technical solution for terminal block mounting structure, the mounting bracket is an integral bent structure.

[0015] As an optional technical solution for the terminal block mounting structure, the wiring through hole is an elliptical hole.

[0019] This utility model provides a terminal block mounting structure, which includes a main housing, a cover plate, and a mounting bracket. The main housing has a wiring through hole and an operating port. The mounting bracket is fixed to the main housing and is used to fix the wiring terminals of the voltage regulator, ensuring that the first wiring port of the terminal block is directly opposite the wiring through hole. The cover plate is connected to the main housing and can selectively close the operating port, which provides operating space for tightening the screws of the terminal block. By designing the cover plate and mounting bracket separately, fixing the mounting bracket to the main housing, and using the mounting bracket to support and fix the terminal block, the installation position and angle of the terminal block are determined. The first wiring port of the terminal block is directly opposite the wiring through hole, facilitating wiring operations.

[0038] Example 1

[0039] As shown in Figures 1 to 6, this embodiment provides a terminal block mounting structure and a voltage regulator. The voltage regulator includes a terminal block 30 and a terminal block mounting structure. The terminal block mounting structure includes a main housing 21, a cover plate 22, and a mounting bracket 10. The main housing 21 has a wiring through hole 212 and an operating port 211. The mounting bracket 10 is fixed to the main housing 21 and is used to fix the terminal block 30 of the voltage regulator, with the first wiring port 31 of the terminal block 30 facing the wiring through hole 212. The cover plate 22 is connected to the main housing 21 and can selectively close the operating port 211. The operating port 211 provides operating space for screwing the terminal block 30.

[0040] By designing the cover plate 22 and the mounting bracket 10 separately, the mounting bracket 10 is fixed on the main housing 21, and the mounting bracket 10 is used to support and fix the terminal block 30, so as to determine the setting position and angle of the terminal block 30. The first wiring port 31 of the terminal block 30 is directly opposite the wiring through hole 212, which facilitates wiring operation. The wiring through hole 212 and the operation port 211 are provided on the main housing 21. When the cover plate 22 is opened, the user can insert the first wire at the wiring through hole 212 and tighten the screw of the terminal block 30 at the operation port 211. The mounting bracket 10 provides a fixed force point for wiring, improves the wiring firmness, and reduces the possibility of wiring loosening.

[0041] Specifically, the main housing 21 has an L-shaped cross-section, with the wiring through hole 212 and the operation port 211 both located on the side of the main housing 21. The mounting bracket 10 is fixed to the bottom surface of the main housing 21. The cover plate 22 is fixed to the main housing 21 with screws. Referring to Figures 1 and 5, when the cover plate 22 is fixed to the main housing 21, the cover plate 22 closes the operation port 211. When the cover plate 22 is removed from the main housing 21, the operation port 211 is exposed.

[0042] Furthermore, the mounting bracket 10 includes a support portion 11 and a bearing portion 12. The support portion 11 is fixed to the main housing 21, and the bearing portion 12 is connected to the support portion 11. The bearing portion 12 is used to support the wiring terminal 30. In this embodiment, two support portions 11 are provided at intervals. The bottom of the support portion 11 is connected to the bottom surface of the main housing 21, and the bearing portion 12 is connected to the top of the two support portions 11.

[0043] Optionally, the mounting bracket 10 is a one-piece bent structure. By setting the mounting bracket 10 as a one-piece bent structure, there is no need to assemble parts, reducing the installation error rate. In addition, the integral molding reduces welding or splicing nodes, reduces the risk of stress concentration, and helps to extend the service life.

[0044] The mounting bracket 10 has a positioning boss 111 on the side of the mounting bracket 10 near the side of the main housing 21. The positioning boss 111 is used to fit against the side of the main housing 21. By providing the positioning boss 111 on the side of the mounting bracket 10 near the side of the main housing 21, the mounting position of the mounting bracket 10 is restricted when welding the mounting bracket 10 by fitting the positioning boss 111 against the side of the main housing 21.

[0045] In this embodiment, the support part 11 is provided with a positioning boss 111 on the side of the main housing 21; when the positioning boss 111 is attached to the side of the main housing 21, it indirectly restricts the relative position of the bearing part 12 and the side of the main housing 21.

[0046] In this embodiment, the mounting bracket 10 is welded to the main housing 21. By welding, the support portion 11 of the mounting bracket 10 is fixed to the main housing 21. The weld joint has high strength, effectively limiting the displacement of the mounting bracket 10 and preventing loosening during long-term use. It is understood that the specific welding process needs to be selected based on the structure and material characteristics, such as arc welding, gas shielded welding, and resistance welding. Specifically, the bottom of the support portion 11 contacts and is welded to the bottom surface of the main housing 21, and the positioning boss 111 fits against the side surface of the main housing 21.

[0047] Optionally, the mounting bracket 10 has a support ramp 121 that extends downward at an incline toward the wiring through hole 212. The support ramp 121 supports the terminal block 30 and positions the screw of the terminal block 30 toward the operating port 211. By providing the support ramp 121 on the mounting bracket 10, which extends downward at an incline toward the wiring through hole 212, the mounting angle of the terminal block 30 after fixing is appropriate, and the screw of the terminal block 30 can face the operating port 211, which helps the user to operate and tighten the screw at the operating port 211.

[0048] In this embodiment, the top surface of the bearing portion 12 has a bearing inclined surface 121, and the wiring terminal 30 is fixed to the bearing portion 12 and fits against the bearing inclined surface 121.

[0049] Furthermore, the screws of the terminal block 30 include a wiring screw and an internal screw, which are arranged side by side at intervals. The internal screw is located on the side of the wiring screw away from the operating port 211. The bearing inclined surface 121 forms a preset angle with the horizontal plane, and the operating port 211 is set in a preset shape, so that only the wiring screw can be turned from the operating port 211. The first wiring port 31 on the terminal block 30 is used for inserting the first wire, the wiring screw is used to clamp and fix the first wire, and the internal screw of the terminal block 30 is used to clamp the second wire connected to the internal components of the voltage regulator. By setting the bearing inclined surface 121 to form a preset angle with the horizontal plane and setting the operating port 211 to a preset shape, only the wiring screw can be turned at the operating port 211, preventing the user from turning the internal screw at the operating port 211 and causing the internal screw to loosen, effectively solving the problem of misoperation.

[0050] Specifically, the terminal block 30 has a first wiring port 31 and a second wiring port 32 on both sides. The first wiring port 31 is used for inserting a first wire, and the second wiring port 32 is used for inserting a second wire. The top of the terminal block 30 has a row of first mounting holes 33 and a row of second mounting holes 35. The first mounting holes 33 and the second mounting holes 35 are arranged side by side with intervals. The second mounting holes 35 are located on the side of the first mounting holes 33 away from the operating port 211. The first mounting holes 33 are used to install wiring screws, and the second mounting holes 35 are used to install internal screws.

[0051] In this embodiment, the operating port 211 is rectangular, with a preset angle range of 10 to 30 degrees; the vertical height of the operating port 211 is set according to the angle between the bearing inclined surface 121 and the horizontal plane. In other embodiments, the preset angle and preset shape need to be adjusted according to the actual dimensions of the terminal block mounting structure.

[0052] Referring to Figures 3 and 6, optionally, the terminal block 30 is detachably fixed to the support portion 12 via a connector. In this embodiment, the top of the terminal block 30 is also provided with a row of first fixing holes 34, which are located between a row of first mounting holes 33 and a row of second mounting holes 35; the support portion 12 is provided with threaded holes 122, and the connector passes through the first fixing holes 34 and is threadedly connected to the threaded holes 122; the terminal block 30 is kept at an appropriate distance from the side of the main housing 21; the connector can be a screw or a bolt.

[0053] Specifically, at least two of each of the first fixing holes 34 and threaded holes 122 are provided, and the positions of the first fixing holes 34 and threaded holes 122 are matched. In this embodiment, four first fixing holes 34 are arranged side by side with intervals, and two threaded holes 122 are arranged side by side with intervals.

[0054] Optionally, the wiring through-hole 212 is an elliptical hole. By setting the wiring through-hole 212 to an elliptical shape, it can be adapted to the design of the bearing inclined surface 121 on the mounting bracket 10, so that the terminal block 30 is fixed on the bearing inclined surface 121 to meet the wiring requirements. In this embodiment, the wiring through-hole 212 penetrates the side of the main housing 21 in the horizontal direction, the long axis of the wiring through-hole 212 is set in the vertical direction, and the long axis of the wiring through-hole 212 is set in the horizontal direction.

[0055] Optionally, a protective sleeve 40 is provided on the wall of the wiring through hole 212. By providing a protective sleeve 40 on the wall of the wiring through hole 212, wear and compression on the first wire can be reduced, and dust and moisture can be prevented from entering.

[0056] The following is a detailed explanation of the usage process for the wiring screw mounting structure:

[0057] First, remove the cover plate 22 from the main housing 21. Pass the first wire through the wiring through hole 212 on the main housing 21 and insert it into the first wiring port 31 of the terminal 30. The user holds a screwdriver and inserts it into the operating port 211. The user uses the screwdriver to tighten the wiring screw located at the first mounting hole 33 of the terminal 30 so that the wiring screw presses the first wire. Finally, fix the cover plate 22 to the main housing 21.

[0058] Example 2

[0059] As shown in Figures 7 and 8, compared with Embodiment 1, the specific structure of the mounting bracket 10 and the connection method between the mounting bracket 10 and the main housing 21 differ in Embodiment 2. Specifically, the terminal mounting structure also includes fasteners. The mounting bracket 10 includes a support portion 11 and a bearing portion 12. Two support portions 11 are respectively connected to both ends of the bearing portion 12. The bearing portion 12 is used to fix the terminal 30, and the support portion 11 is detachably fixed to the main housing 21 by fasteners. In this embodiment, the mounting bracket 10 is U-shaped. The bearing portion 12 is provided with a bearing inclined surface 121 for supporting the terminal 30. The support portion 11 is provided with a second fixing hole 112, and the fastener passes through the second fixing hole 112 and is connected to the main housing 21. The fastener can be a bolt or a screw.

[0060] By providing a second fixing hole 112 on the support part 11 and providing a hole position corresponding to the second fixing hole 112 on the main housing 21, the installation position of the mounting bracket 10 can be accurately guaranteed.
