Description

Technical Field

[0001] This utility model relates to the field of electromechanical technology, specifically to a terminal box for an electric motor. Background Technology

[0002] In motor systems, the terminal box, as a key component, plays a crucial role in connecting the motor's internal windings to the external circuitry. As a widely used power device in various mechanical fields, the stable operation of a motor relies on efficient and reliable electrical connections, and the terminal box is the core hub for achieving this connection. It not only provides a platform for leading out and connecting the motor's internal coils and related electrical components, but also ensures the stability and safety of the electrical connection through fixed terminals.

[0003] However, when using existing junction boxes, accidental dragging from the outside can cause instability in the connection of the motor wires, making them prone to detachment. This can lead to unstable current supply, poor contact, and other circuit problems, resulting in low machine efficiency and a high failure rate. Utility Model Content

[0004] This utility model provides a terminal box for motors to solve the problem of unstable connection. Unstable connection can cause the motor wires to move and fall off easily, resulting in unstable current supply and poor contact circuit problems, which in turn leads to low machine efficiency and high failure rate.

[0005] This utility model provides the following technical solution: a terminal box for a motor, comprising a terminal box body, and further comprising: two sets of wiring pipes disposed on the left side of the terminal box body, wherein a base plate is fixedly connected to the bottom surface of the terminal box body; fixing components disposed inside the two sets of wiring pipes, wherein each of the two fixing components comprises a threaded rod, a rotary valve, a fixing pad, and a clamping block; and a heat dissipation component disposed on the front side of the terminal box body, wherein the heat dissipation component comprises several sets of heat dissipation fins, a heat dissipation plate, and a fan.

[0006] As a preferred embodiment of this utility model, the two sets of threaded rods are arranged inside the two sets of wiring pipes, one end of each set of threaded rods is fixedly connected to a rotary valve, the other end of each set of threaded rods is fixedly connected to a fixing pad, and the outer side of each set of threaded rods is rotatably connected to a clamping block.

[0007] As a preferred embodiment of this utility model, several sets of heat dissipation fins are arranged on the front of the cable outlet box body, and one end of each set of heat dissipation fins is fixedly connected to a heat dissipation plate, with a fan installed inside the heat dissipation plate.

[0008] As a preferred embodiment of this utility model, each of the two sets of wiring pipes is fixedly connected to a fixing block, and the size of the two sets of fixing blocks is equal to the size of the two sets of clamping blocks.

[0009] As a preferred technical solution of this utility model, the outlet box body is provided with a shielding layer inside, and a sound insulation layer is fixedly connected inside the shielding layer.

[0010] As a preferred technical solution of this utility model, the top surface of the outlet box body is provided with several sets of threaded holes, and the interior of each of the several threaded holes is threaded with a spiral nail.

[0011] As a preferred technical solution of this utility model, the top surface of the outlet box body is connected to a top cover, and the surface of the top cover is provided with a number of limiting holes.

[0012] As a preferred technical solution of this utility model, the base plate has a number of positioning holes inside, and each of the positioning holes is threaded with a threaded nail.

[0013] Compared with the prior art, this utility model provides a terminal box for a motor, which has the following advantages:

[0014] This motor outlet box, through the setting of the fixing component, allows the motor wire to be inserted into the wiring tube during use. Rotating the rotary valve causes the threaded rod to rotate, which moves vertically on the wiring tube, pushing the clamping block downward to fix the motor wire. This keeps the wire in a stable position inside the wiring tube, enhancing the reliability of the connection between the wire and the terminal and reducing circuit failures caused by poor contact.

[0015] This outlet box for motors utilizes a heat dissipation component. During use, the heat dissipation fins are tightly fitted to the outer shell of the outlet box, quickly absorbing the heat generated by the electrical components inside the box during operation. A fan continuously blows air onto the heat dissipation fins, accelerating the airflow on the fin surface. Through forced convection, a large amount of heat is carried away, preventing the electrical components from degrading in performance, aging prematurely, or even burning out due to high temperatures. This further protects the safety and stability of the internal circuitry and extends the overall service life of the outlet box. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model discloses a terminal box for a motor, including a terminal box body 1, and further including: two sets of wiring pipes 2 disposed on the left side of the terminal box body 1, and a base plate 3 fixedly connected to the bottom surface of the terminal box body 1; fixing components 4 disposed inside the two sets of wiring pipes 2, each of the two fixing components 4 including a threaded rod 401, a rotary valve 402, a fixing pad 403 and a clamping block 404; and a heat dissipation component 5 disposed on the front side of the terminal box body 1, the heat dissipation component 5 including several sets of heat dissipation fins 501, a heat dissipation plate 502 and a fan 503.

[0023] Specifically, two sets of threaded rods 401 are installed inside two sets of wiring pipes 2. One end of each set of threaded rods 401 is fixedly connected to a rotary valve 402, and the other end of each set of threaded rods 401 is fixedly connected to a fixing pad 403. A clamping block 404 is rotatably connected to the outside of each set of threaded rods 401.

[0024] In this embodiment, rotating the rotary valve 402 causes the threaded rod 401 to rotate. The threaded rod 401 rotates and moves vertically inside the wiring tube 2, pushing the clamping block 404 downward to fix the motor wire. This keeps the motor wire in a stable position inside the wiring tube 2, increasing the reliability of the connection between the wire and the terminal and reducing the occurrence of circuit failures.

[0025] Specifically, several sets of heat dissipation fins 501 are all arranged on the front of the cable outlet box body 1, and one end of the several sets of heat dissipation fins 501 is fixedly connected to a heat dissipation plate 502, and a fan 503 is arranged inside the heat dissipation plate 502.

[0026] In this embodiment, the heat dissipation fins 501 are in close contact with the outer shell of the junction box to accelerate the absorption of heat generated inside the box. The heat dissipation plate 502 is fixed to the heat dissipation fins 501 to ensure that the position of the heat dissipation fins 501 does not change. The fan 503 continuously blows air towards the heat dissipation fins 501 to accelerate the airflow on the surface of the heat dissipation fins 501 and remove a large amount of heat to avoid problems such as performance degradation and aging of electrical components due to excessive temperature. This further protects the safety and stability of the internal circuit and extends the overall service life of the junction box.

[0027] Specifically, each of the two sets of wiring pipes 2 has a fixing block 6 fixedly connected inside, and the size of the two sets of fixing blocks 6 is equal to the size of the two sets of clamping blocks 404.

[0028] In this embodiment, the electromechanical wires are fixed by the mutual pressing of the fixing block 6 and the clamping block 404, ensuring that the position of the electromechanical wires in the outlet box does not change or shift, thereby improving the overall safety and stability of the outlet box and reducing circuit failures caused by poor contact.

[0029] Specifically, the outlet box body 1 has a shielding layer 7 inside, and a sound insulation layer 8 is fixedly connected inside the shielding layer 7.

[0030] Specifically, the top surface of the outlet box body 1 is provided with several sets of threaded holes, and each of the threaded holes is threaded with a spiral nail 9.

[0031] In this implementation scheme, the shielding layer 7 reduces the impact of external electromagnetic interference on the function of the outlet box, and the sound insulation layer 8 insulates the sound generated by the operation inside the outlet box, thereby reducing the noise generated by the outlet box during operation and reducing the noise pollution level during use.

[0032] Specifically, the top surface of the outlet box body 1 is connected to a top cover 10, and the surface of the top cover 10 is provided with several sets of limiting holes.

[0033] Specifically, the base plate 3 has several sets of positioning holes inside, and each of the positioning holes is threaded with a threaded pin 11.

[0034] The working principle and usage process of this utility model are as follows: When in use, the motor wire is inserted into the wiring tube 2, and the rotary valve 402 is rotated. The rotation of the rotary valve 402 drives the threaded rod 401 to rotate. The threaded rod 401 rotates and moves vertically on the wiring tube 2, pushing the clamping block 404 to move downward to fix the motor wire, so that the wire maintains a stable position in the wiring tube 2, which enhances the reliability of the connection between the wire and the terminal and reduces circuit failures caused by poor contact.

[0035] During use, the heat sink 501 fits tightly against the outer shell of the junction box, quickly absorbing the heat generated by the electrical components inside the box during operation. The fan 503 continuously blows air onto the heat sink 501, accelerating the airflow on the surface of the heat sink 501. Through forced convection, a large amount of heat is carried away, preventing the electrical components from degrading, aging, or even burning out due to high temperatures. This further protects the safety and stability of the internal circuitry and extends the overall service life of the junction box.

[0036] In summary, the junction box for the motor, through the setting of the fixing component 4 and the heat dissipation component 5, can fix the motor wires so that the wires maintain a stable position inside the junction box 2, and at the same time avoid the impact of high temperature inside the device.
