Description

Technical Field

[0001] The invention relates to the technical field of terminal sockets, in particular to a motor terminal socket with a heat dissipation function. Background Art

[0002] The motor terminal block is an important part of the motor used to connect the external power supply and the internal winding of the motor. The motor terminal block plays a vital role in the operation of the motor. It is not only a key node for power transmission, but also related to the safe and stable operation of the motor. If there is a problem with the terminal block, such as poor contact, short circuit, etc., it may cause the motor to not work properly, and even cause serious consequences such as electrical fires.

[0003] In this regard, the patent document with publication number CN209516807U discloses a motor terminal socket with heat dissipation function, including a motor rear end cover and a terminal socket body fixed on the motor rear end cover, a cooling pipe is arranged in the motor rear end cover, and the terminal socket body includes an insulating shell and a copper block arranged inside the insulating shell, and the thickness of the insulating shell between the copper block and the motor rear end cover is limited to reduce thermal resistance on the premise of meeting electrical strength, and make full use of the motor rear end cover to cool the temperature rise of the winding; in addition, the three-phase line of the controller, the three-phase line of the motor and the neutral line of the motor are all led out and connected to the terminal socket body, and with the help of its own high thermal conductivity characteristics and the insulating shell made of high thermal conductivity insulating material, the heat inside the controller and the motor is conducted to the cooling pipe of the motor rear end cover through the terminal socket body, thereby further reducing the temperature of the motor.

[0004] The motor will generate a lot of heat during operation, and the terminal block, as a key part connecting the motor to the external power supply, will also be affected by the heat of the motor. Due to the shortcomings of the existing design in heat dissipation, heat is easily accumulated at the terminal block, which will not only affect the service life of the terminal block itself, but may also cause the insulation layer of the connected wire to age faster, increasing the risk of electrical failures. Secondly, the terminal blocks of many motors are exposed and have not undergone effective protective measures. In this case, the exposed terminal blocks pose a great safety hazard and are easily touched by people by mistake. Especially in some workplaces, where people are active frequently, if they accidentally touch the live terminal block, it may cause an electric shock accident, posing a serious threat to the life safety of the personnel, and the safety performance is extremely poor.

[0005] In view of the above problems, a motor terminal block with heat dissipation function is proposed. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0030] Combination Figure 1-Figure 6 A motor terminal block with heat dissipation function of the present invention comprises a terminal box 11, an isolation cover 12 is connected to the opening position of the terminal box 11, a partition net 13 is connected to the inside of the isolation cover 12, a top strip 14 is connected to the inner side of the partition net 13, a heat dissipation component 2 and a reset component 3 are both embedded in the inside of the terminal box 11, and the heat dissipation component 2 and the reset component 3 arranged in the terminal box 11 are isolated by the isolation cover 12 and the partition net 13;

[0031] This helps to manage the heat dissipation component 2 that generates more heat and the reset component 3 with specific functions separately from other electrical components in the junction box 11. The heat dissipation port 24 can promote air circulation and accelerate heat dissipation, while the isolation cover 12 and the partition net 13 will not hinder the heat dissipation process, ensuring that the heat of the motor terminal block during operation can be discharged in a timely and effective manner, thereby alleviating various problems caused by poor heat dissipation.

[0032] A heat dissipation component 2 is arranged inside the junction box 11. The heat dissipation component 2 includes a wiring plate 21. The surface of the wiring plate 21 is connected to a terminal post 22. The outer surface of the terminal post 22 is wrapped with a protective cover 23. Four groups of protective covers 23 are arranged. The four groups of protective covers 23 are connected together by an integration rod 25. The four groups of protective covers 23 are included on the terminal post 22. A heat dissipation port 24 is opened on the protective cover 23. The protective cover 23 is a cylindrical structure made of insulating material. Heat dissipation ports 24 are opened above and below the protective cover 23. The heat dissipation ports 24 are covered with a plastic net. The heat dissipation ports 24 are used to dissipate heat inside the protective cover 23. The top of the protective cover 23 is connected to an integration rod 25. A ventilation net 26 arranged on the integration rod 25 plays an isolation role. A cooling fan is installed on the ventilation net 26. The cooling fan drives air to pass through faster. A ventilation net 26 is opened inside the integration rod 25.

[0033] In the heat dissipation of the motor terminal block, under normal working conditions, the protective cover 23 is not wrapped around the terminal post 22, so that the heat can be directly diffused to the inside of the terminal box 11. When a heat dissipation fan is installed on the ventilation net 26, the rotation of the heat dissipation fan blades can discharge the heat inside the terminal box 11 through the partition net 13, thus ensuring the internal temperature and increasing the safety of the terminal block operation;

[0034] In terms of safety, not only is a separation net 13 provided for isolation, but also a protective cover 23 is provided. When the isolation cover 12 and the separation net 13 are separated from the junction box 11, the protective cover 23 will quickly wrap around the terminal 22, thus avoiding electric shock caused by accidental touch. The specific operation is as follows:

[0035] The terminal box 11 is connected to a reset assembly 3, which includes a mounting frame 32. A guide rod 31 is connected to the terminal box 11. The guide rod 31 passes through the interior of the integration rod 25. The guide rod 31 and the integration rod 25 are slidably connected. A transmission gear 33 is connected to the bottom end of the mounting frame 32. A rack 38 is connected to the integration rod 25. The rack 38 and the transmission gear 33 are meshed. A positioning groove 34 is also connected to the terminal box 11. A propulsion tooth 35 is embedded in the positioning groove 34. One side of the transmission gear 33 is meshed with the rack 38, and the other side is meshed with the propulsion tooth 35. The propulsion tooth 35 and the positioning groove 34 are meshed. The grooves 34 are slidingly connected, a return spring 37 is connected to one side of the propulsion tooth 35, and a feedback strip 36 is connected to the other side of the propulsion tooth 35. The propulsion tooth 35 and the feedback strip 36 are combined in an L shape, the feedback strip 36 corresponds to the top strip 14, the top strip 14 abuts on the surface of the feedback strip 36, and the return spring 37 is embedded in the interior of the positioning groove 34. One end of the return spring 37 is connected to the junction box 11, and the other end of the return spring 37 is connected to the propulsion tooth 35. When the isolation cover 12 is installed at the opening position of the junction box 11, the top strip 14 abuts on the feedback strip 36, and the return spring 37 is in a compressed state.

[0036] When the isolation cover 12 and the separation net 13 are installed on the junction box 11 through the connecting piece, the top strip 14 on the separation net 13 and the feedback strip 36 are in conflict. When the feedback strip 36 is moved inward as the isolation cover 12 approaches the junction box 11, the feedback strip 36 is continuously pushed inward. After the feedback strip 36 moves inward, it drives the propulsion tooth 35 to move. When the propulsion tooth 35 moves inside the positioning groove 34, the reset spring 37 is compressed. At the same time, the propulsion tooth 35 moves and drives the transmission gear 33 to rotate. When the transmission gear 33 rotates The rack 38 is driven to move, and the moving direction of the rack 38 is opposite to the moving direction of the propulsion tooth 35. The propulsion tooth 35 moves outward and drives the integration rod 25 to move. When the integration rod 25 moves under the guidance of the guide rod 31, it drives the protective cover 23, and the protective cover 23 is separated from the terminal 22. In this way, the terminal 22 can be better exposed to the inside of the terminal box 11, and the air circulation is smoother in heat dissipation, which increases the heat dissipation of the inside and avoids the temperature rise caused by internal heat redundancy.

[0037] When the isolation cover 12 is detached from the terminal box 11, the reset spring 37 will be quickly reset. When the reset spring 37 is reset, it will push the propulsion tooth 35 to move inward. At the same time, the protective cover 23 also moves inward. The protective cover 23 contacts the terminal plate 21, thereby wrapping the terminal post 22 and increasing the protection of the terminal post 22. This can also avoid accidental touching of the terminal post 22 and causing electric shock. Through such a design, the safety of personnel can be guaranteed when the isolation cover 12 and the partition net 13 are prevented from accidentally falling.
