[0002] With the continuous improvement of people's living standards, people have more and more demands for electromechanical equipment in their daily lives, from transportation to various household appliances, computers, printers, etc., which have become indispensable electromechanical products in people's lives. When coal mine workers connect motor wires, they often use the motor wiring connection structure of coal mine electromechanical equipment.
[0003] Technicians engaged in this industry have found that in order to ensure the stability of the motor connecting wires of coal mine electromechanical equipment, the workers install the connecting structures very tightly to prevent the motor connecting wires from loosening and falling off during use, thereby breaking the circuit and causing damage to the coal mine electromechanical equipment. However, the connecting structure and the connecting wires are installed too tightly, which makes it difficult for the workers to separate the connecting structure. Therefore, they need to shake the connecting structure left and right. Shaking the connecting structure left and right for a long time can easily squeeze the metal head inside the connector, causing the metal head to shift, affecting the use of the connector. For this reason, we propose a wiring connection structure for coal mine electromechanical equipment motors. Utility Model Content

However, the connecting structure and the connecting wires are installed too tightly, which makes it difficult for the workers to separate the connecting structure. Therefore, it is necessary to shake the connecting structure left and right. Shaking the connecting structure left and right for a long time is likely to squeeze the metal head inside the connecting head, thereby causing the metal head to shift, affecting the use of the connecting head.

[0013] The beneficial effects of the utility model are as follows:
[0014] 1. When the utility model is in use, the connecting tube connected to the connecting seat is first rotated to make the connecting tube and the plug be threadedly connected, so that the connecting head is inserted into the slot, and the connecting hole in the connecting head is connected to the metal column inside the plug, so that the connecting tube can stably connect the connecting head to the plug, and then the connecting head is connected to the power supply through the wire. When the connecting head needs to be removed from the plug, the connecting tube is rotated in the opposite direction to make the connecting tube pull out of the plug with the connecting head through the connecting seat, so that the staff can separate the connecting head and the plug more easily, and avoid the staff shaking the connecting head and the plug left and right, which will cause damage to the metal column inside the plug and affect the conductive performance of the metal column.
[0015] 2. When the utility model is in use, the diameter of the slot is consistent with the diameter of the connector, which can reduce the gap between the slot and the connector, thereby preventing excessive dust from falling into the connecting hole through the gap between the slot and the connector, thereby affecting the conductivity between the connecting hole and the metal column.

[0024] In this embodiment, preferably, the diameter of the connector 2 is smaller than the inner diameter of the connecting tube 5. By making the diameter of the connector 2 smaller than the inner diameter of the connecting tube 5, the connector 2 can be stably inserted into the interior of the plug 8 during the rotation of the connecting tube 5.
[0025] In this embodiment, preferably, the size of the swivel 6 is consistent with the size of the annular groove 7; when the size of the swivel 6 is consistent with the size of the annular groove 7, the gap between the swivel 6 and the annular groove 7 can be reduced, thereby allowing the connecting tube 5 to rotate more stably.

When the connecting head 2 needs to be removed from the plug 8, the connecting tube 5 is rotated in the opposite direction to allow the connecting tube 5 to be pulled out of the plug 8 with the connecting head 2 through the connecting seat 1, so that the staff can more easily separate the connecting head 2 and the plug 8, and avoid the staff from shaking the connecting head 2 and the plug 8 left and right, causing damage to the metal column 11 inside the plug 8, affecting the conductive performance of the metal column 11.
