Technical Field
[0001] The invention belongs to the technical field of motor control, and in particular relates to a motor terminal socket capable of cooling and dissipating heat. Background Art
[0002] The motor terminal block is a component installed on the motor housing, mainly used to connect the internal winding of the motor with the external power line. It plays a vital role in the motor circuit connection to ensure that the motor receives power supply normally and safely. During the operation of the motor, the terminal block is required to connect the power supply to the motor stator. The traditional terminal block structure includes: an insulating base, three copper bars, six hexagonal nuts and four bushings.
[0003] The existing motor terminal block uses nuts to fix the copper busbar, terminal block, and wire group. However, the vibration generated by the motor working for a long time can cause the nut to loosen, resulting in incomplete contact between the copper busbar, terminal block, and wire group, that is, virtual connection, resulting in the motor not working or the line temperature being too high. Secondly, the motor working for a long time will cause the temperature of the copper busbar and wire group inside the terminal block to be too high. If the heat is not discharged in time, it is easy to cause the copper busbar and wire group to burn out. However, the existing terminal block dissipates heat through air medium, and its heat dissipation effect is poor. Summary of the invention
[0004] The object of the present invention is to provide a motor terminal block capable of cooling and dissipating heat, so as to solve the problems raised in the above-mentioned background technology.

[0013] 1. The present invention pulls the pull rod in the installation groove to move the insulating pressure plate forward along the slide rod and squeeze the reset spring, so that the copper busbar and the line head are sleeved on the terminal. The pull rod is loosened, and the reset spring pushes the insulating pressure plate to reset and presses the copper busbar and the line head to complete the line connection. During the process, the upper end of the pull rod will contact the rubber pad in the rectangular groove, so that the copper busbar and the line head connected between the pull rod and the terminal are pressed and limited, thereby solving the problem of loose nuts due to the vibration generated by the motor in the existing wiring method, resulting in poor contact or false connection.
[0014] 2. The present invention adds a proper amount of coolant to the interior of the shell, that is, the upper surface of the partition, and resets the sliding limit rod, so that the coolant immerses the terminal, copper busbar, and line, thereby quickly dissipating the heat from the motor to the outside through the coolant, avoiding the problem that the temperature of the copper busbar and the wire group inside the terminal block is too high, and the heat is not discharged in time, resulting in the burning of the copper busbar and the wire group. At the same time, the coolant can effectively prevent dust from contacting the line and avoid the influence of dust on the line. The connecting rod can be rotated to move the coolant downward to expose the line, avoiding the inconvenience caused by the coolant when repairing the line. BRIEF DESCRIPTION OF THE DRAWINGS

Its function is to take out the sealing block 4 in the bobbin 3, pass the motor wire or the power wire through one of the side wire holes 2 and the bobbin 3, and then pass it through the middle of the sealing block 4. During the process of pressing the sealing block 4 to move backward, the rear end of the sealing block 4 is squeezed by the inside of the bobbin 3, so that the motor wire or the power wire, the sealing block 4, and the bobbin 3 are sealed to avoid leakage of coolant.

When the partition 7 moves to a suitable position, the outer ends of the connecting rods 10 stop moving, and the sliding limit rods 13 are slid to the lowermost end to limit the connecting rods 10. The multiple compression springs 6 cannot move the partition 7 forward.

[0032] The present invention is placed horizontally, and a proper amount of coolant is added to the interior of the shell 1, i.e., the upper surface of the partition 7. The sliding limit rod 13 is reset, and the connecting rod 10 is released from the restriction. The multiple compression springs 6 will push the partition 7 and the upper coolant to move upward until they contact the lower surface of the limit frame 8, and the cover 16 is slid closed. During the process, the upper end of the pull rod 25 will contact the rubber pad 18 in the rectangular groove 17, so that the connecting copper bus and the line head between the insulating pressure plate 22 and the terminal 20 are pressed and limited by the insulating pressure plate 22, and the space between the cover 16 and the partition 7 is filled with coolant. When the motor is working, the heat generated by the line will be absorbed by the coolant, thereby cooling the line.
