Description

Technical Field

[0001] This utility model relates to the field of coil clamp technology, specifically a lead wire clamp. Background Technology

[0002] Ductless air conditioners are terminal devices in central air conditioning systems. They work by using a fan to drive airflow, allowing heat exchange between the air and a heat exchanger, thus heating or cooling the air. Ductless air conditioners offer advantages such as uniform airflow and high comfort, and are widely used in air conditioning systems of large commercial buildings, office buildings, hospitals, and other similar locations. As the core power component, the design of the motor's lead-out clamp directly affects the safety and lifespan of the equipment.

[0003] Currently, the lead wire clamps for commercial 1.5 / 3 HP ducted air conditioner motors only support the lead wires of 3, which cannot meet the connection requirements of 5 power wires in some application scenarios, thus limiting the product's applicability. Secondly, the lead wire area is susceptible to corrosion from environmental factors such as dust and moisture, which may lead to a decline in insulation performance and even cause safety hazards such as short circuits with long-term use. Utility Model Content

[0004] The purpose of this invention is to provide a lead wire clamp to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lead wire clamp is fixedly connected to the outside of the motor and is used to connect the motor windings to an external circuit. The motor is fixedly connected to the inside of the support by a clamp. A coupling is rotatably connected inside the motor. The lead wire clamp is formed by the snap-fit ​​of an upper clamp and a lower clamp. The top inner sides of both the upper and lower clamps have recessed cavities that form protective chambers to protect the lead wires. A backing plate is fixedly connected to the inner side of the upper clamp, and a lead wire plate is fixedly connected to the inner side of the lower clamp. The backing plate and the lead wire plate cooperate to fix the lead wires.

[0008] Preferably, the abutment plate and the outlet plate are staggered, the outlet plate is divided into a slot, and the abutment plate is located above the slot.

[0009] Preferably, the lower end face of the upper clamping plate is fixedly connected with a downwardly extending buckle, and the buckle is distributed on both sides of the protective chamber.

[0010] Preferably, the upper surface of the lower clamping plate is provided with a slot, the slot extends through the lower clamping plate to the lower end surface, the slots are distributed on both sides of the protective chamber, and the positions of the buckle and the slot are perpendicularly corresponding.

[0011] Preferably, a boss is fixedly connected to the lower end face of the upper clamping plate, and the boss is distributed at the four corners of the upper clamping plate.

[0012] Preferably, the upper surface of the lower clamping plate is provided with column grooves, which are distributed at the four corners of the lower clamping plate and are perpendicular to the positions of the boss columns.

[0013] Preferably, a heat dissipation cavity is fixedly connected to the upper end face of the upper clamping plate, and the position of the heat dissipation cavity is perpendicular to the abutment plate.

[0014] Preferably, the upper surface of the protective chamber is provided with a lead wire outlet, and the lower surface of the contact plate is provided with a lead wire inlet.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

Compared to existing technologies, the number of lead wires that can be extended from three to five. Simultaneously, the lead wires are completely fixed in place by the inner abutment plate of the upper clamping plate.

[0017] In this invention, the upper clamping plate and the lower clamping plate are fitted together to form a protective chamber. There is a suitable interference fit between the inner diameter of the protective chamber and the outer diameter of the PVC sleeve of the lead wire, which generates a certain amount of extrusion force, making the gap between the two smaller and effectively preventing dust and moisture from entering.

[0018] In this invention, the upper clamping plate is provided with buckles with hooks on both sides of the protective chamber. The buckle hooks return to their original position to quickly hook into the slot, so that the upper clamping plate and the lower clamping plate are tightly closed to prevent the lead wire clamping plate from loosening.

Detailed Implementation

[0026] 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.

[0027] Example:

[0028] Please see Figures 1 to 6 This utility model provides a technical solution:

[0029] A lead wire clamp, comprising:

[0030] Lead wire clamp 1 is fixedly connected to the outside of motor 7 and is used to connect the winding of motor 7 to external circuit. Motor 7 is fixedly connected to the inside of support 8 by clamp. Coupling 9 is rotatably connected inside motor 7. Lead wire clamp 1 is formed by snapping together upper clamp 5 and lower clamp 6. The top inner side of upper clamp 5 and lower clamp 6 both have recessed cavities, which form protective chambers 3 to protect the lead wire. A stop plate 503 is fixedly connected to the inside of upper clamp 5 and a lead wire plate 602 is fixedly connected to the inside of lower clamp 6. The stop plate 503 and lead wire plate 602 cooperate to fix the lead wire.

[0031] In this embodiment, the lower clamping plate 6 is provided with 6 lead-out plates 602 of different widths. The lead-out plates 602 are divided into 5 slots of the same width. The width of the slots is almost the same as the width of the lead wire and its outer PVC sleeve. The lead wire of the motor 7 winding can pass through the slot through the lead wire inlet 401 opened on the lower abutment plate 4. At the same time, 5 or 3 lead wires are led out to the protective chamber 3. The lead wire and its outer PVC sleeve are inserted into the slot. Then the upper clamping plate 5 is covered. The upper clamping plate 5 is provided with 5 abutment plates 503 of the same width. The position of the abutment plates 503 is the same as the position of the slots divided by the lead-out plates 602. The width of the abutment plates 503 is slightly smaller than the width of the slots. When the upper clamping plate 5 and the lower clamping plate 6 are closed, the abutment plates 503 abut against the lead wire in the slot from above, thereby completely fixing the lead wire by the upper clamping plate 5 and the lower clamping plate 6.

[0032] Specifically, the abutment plate 503 and the outlet plate 602 are staggered, the outlet plate 602 is divided into a slot, and the abutment plate 503 is located above the slot.

[0033] In this embodiment, the upper clamping plate 5 is provided with hooks 502 on both sides of the protective chamber 3. The hooks 502 are made of elastic composite materials such as PP. When the upper clamping plate 5 and the lower clamping plate 6 are closed, the hooks 502 pass through the slots 601 opened on the lower clamping plate 6. The top of the hooks 502 is squeezed and deformed by the inner wall of the slots 601. When the hook at the top of the hooks 502 passes through the slots 601 and reaches the inclined edge below the slots 601, the hooks of the hooks 502 return to their original position and quickly hook the slots 601, so that the upper clamping plate 5 and the lower clamping plate 6 are tightly closed, preventing the lead wire clamping plate 1 from loosening.

[0034] Specifically, the lower end face of the upper clamping plate 5 is fixedly connected with a downwardly extending buckle 502, which is distributed on both sides of the protective chamber 3.

[0035] Specifically, the upper end face of the lower clamping plate 6 is provided with a slot 601, which extends through the lower clamping plate 6 to the lower end face. The slots 601 are distributed on both sides of the protective chamber 3, and the buckles 502 are perpendicularly corresponding to the positions of the slots 601.

[0036] Specifically, a boss 501 is fixedly connected to the lower end face of the upper clamping plate 5, and the boss 501 is distributed at the four corners of the upper clamping plate 5.

[0037] Specifically, the upper surface of the lower clamping plate 6 is provided with a column groove 603, which is distributed at the four corners of the lower clamping plate 6 and is perpendicular to the position of the boss column 501.

[0038] Specifically, a heat dissipation cavity 2 is fixedly connected to the upper end face of the upper clamping plate 5, and the position of the heat dissipation cavity 2 is perpendicular to the abutment plate 503.

[0039] In this embodiment, the protrusion shape of the protective chamber 3 and the PVC sleeve of the lead wire form a tight fit, ensuring a suitable interference fit between the inner diameter of the protective chamber 3 and the outer diameter of the PVC sleeve. When the PVC sleeve of the lead wire is inserted into the protective chamber 3, this interference fit will generate a certain squeezing force, which will reduce the gap between the two and effectively prevent dust and moisture from entering. At the same time, the lead wire outlet 301 of the protective chamber 3 is tapered, so that the lead wire is neatly arranged after it is led out of the clamp and squeezed against each other to form a relatively sealed opening, thereby maintaining a good sealing effect.

[0040] Specifically, the upper surface of the protective chamber 3 is provided with a lead wire outlet 301, and the lower surface of the contact plate 4 is provided with a lead wire inlet 401.

[0041] In use, the lower clamping plate 6 has six lead-out plates 602 of different widths. The lead-out plates 602 are divided into five slots of the same width. The width of the slots is almost the same as the width of the lead wire and its outer PVC sleeve. The lead wire of the motor 7 winding can pass through the slot through the lead wire inlet 401 opened on the lower abutment plate 4, and five lead wires are led out to the protective chamber 3. The lead wire and its outer PVC sleeve are inserted into the slot. Then the upper clamping plate 5 is covered. The upper clamping plate 5 has five abutment plates 503 of the same width. The position of the abutment plates 503 is the same as the position of the slots divided by the lead-out plates 602. The width of the abutment plates 503 is slightly smaller than the width of the slots. When the upper clamping plate 5 and the lower clamping plate 6 are closed, the abutment plates 503 abut against the lead wire in the slot from above, thereby completely fixing the lead wire by the upper clamping plate 5 and the lower clamping plate 6.

[0042] The upper clamping plate 5 is provided with hooks 502 on both sides of the protective chamber 3. The hooks 502 are made of elastic composite materials such as PP. When the upper clamping plate 5 and the lower clamping plate 6 are closed, the hooks 502 pass through the slots 601 opened on the lower clamping plate 6. The top of the hooks 502 is squeezed and deformed by the inner wall of the slots 601. When the hook at the top of the hooks 502 passes through the slots 601 and reaches the inclined edge below the slots 601, the hooks of the hooks 502 return to their original shape and quickly hook the slots 601, so that the upper clamping plate 5 and the lower clamping plate 6 are tightly closed, preventing the lead wire clamping plate 1 from loosening.

[0043] The protrusion shape of the protective chamber 3 and the PVC sleeve of the lead wire form a tight fit, ensuring a suitable interference fit between the inner diameter of the protective chamber 3 and the outer diameter of the PVC sleeve. When the PVC sleeve of the lead wire is inserted into the protective chamber 3, this interference fit will generate a certain squeezing force, which will reduce the gap between the two and effectively prevent dust and moisture from entering. At the same time, the lead wire outlet 301 of the protective chamber 3 is tapered, so that the lead wire is neatly arranged after it is led out of the clamp and squeezed against each other to form a relatively sealed opening, thereby maintaining a good sealing effect.

[0044] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
