Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor housing which can prevent friction of motor leads. Background Art

[0002] The motor lead refers to the wire that connects the motor winding and leads out of the casing or the winding to the terminal on the motor casing. One end of the motor lead is connected to the terminal of the junction box, and the other end of the motor lead is connected to the winding to ensure the normal operation of the motor.

[0003] In the prior art, the motor leads between the terminal posts of the motor housing and the windings have certain disadvantages. The motor leads generally need to be reserved for a relatively long time, so that the electrode leads are relatively long after the motor terminal posts and the windings are connected. As a result, when the windings rotate or the equipment is running, the long electrode leads are prone to friction, causing the insulation of the electrode leads to wear and affecting the normal operation of the motor, so the long electrode leads need to be wound and tightened. Utility Model Content

[0022] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 As shown, a motor housing for preventing friction of motor leads comprises a motor housing 1, a junction box 2 and two groups of electrode leads 3, the junction box 2 is fixed to the motor housing 1 by bolts, the two groups of electrode leads 3 pass through the interior of the junction box 2, one end of the electrode lead 3 is connected to the winding inside the motor housing 1, and the other end of the electrode lead 3 is connected to the terminal post on the junction box 2; elastic structures 5 are provided on both sides of the junction box 2 and located at the electrode leads 3, the elastic structures 5 comprise receiving grooves 51, the receiving grooves 51 are provided inside the two sides of the junction box 2, the electrode leads 3 all pass through the interior of the receiving grooves 51, two groups of T-slots 52 are provided inside the receiving grooves 51, and the T-slots 52 can be used to remove T-blocks 55 from the T-slots near the middle. 52 is disassembled, a connecting rod 53 is provided inside the T-slot 52, the connecting rod 53 passes through the middle of the two T-slots 52, and T-blocks 55 are sleeved inside the T-slot 52 and at both ends of the connecting rod 53, the T-block 55 is slidably connected to the connecting rod 53, the T-block 55 is slidably connected to the inside of the T-slot 52, and a telescopic spring 54 is provided inside the two T-slots 52 and between the two T-blocks 55, the electrode lead 3 is wound between the two T-blocks 55, the end of the electrode lead 3 is inserted into the interior of the storage groove 51, and then the electrode lead 3 is wound between the two T-blocks 55, and the distance between the T-blocks 55 is shortened, so that the electrode lead 3 is wound between the T-blocks 55.

[0024] In this embodiment, the distance between the two T-blocks 55 is smaller than the length of the storage groove 51, ensuring that there is space inside the storage groove 51 for winding the electrode lead 3, and the edges of the two T-blocks 55 are provided with reserved openings 56, and the electrode lead 3 is wound between the two groups of reserved openings 56. The electrode lead 3 wound around the two groups of reserved openings 56 is not easy to fall off.

[0025] In this embodiment, a connecting hole is provided at the top of the junction box 2, the connecting hole is communicated with the inside of the two T-slots 52, and the connecting rod 53 is located inside the connecting hole. The connecting rod 53 is inserted into the connecting hole, so that the two telescopic springs 54 are sleeved on the connecting rod 53.

[0026] In this embodiment, a clamping structure 4 is provided on both sides of the junction box 2 and inside the storage groove 51. The clamping structure 4 includes a fixing cover 41. The fixing cover 41 is buckled into the inside of the storage groove 51, and the fixing cover 41 is adapted to the shape of the storage groove 51, so as to prevent the electrode lead 3 from being exposed to the outside. Two fixing claws 42 are welded to the inner wall of the fixing cover 41, and clamping grooves 43 are provided on the opposite surfaces of the two fixing claws 42. The electrode lead 3 wound between the two T-blocks 55 can be clamped by the two fixing claws 42, so that the electrode lead 3 is located at the clamping groove 43 of the fixing claw 42, and even if the electrode lead 3 is loose, it is not easy to fall off from between the T-blocks 55.

[0027] In this embodiment, the fixing claws 42 and the clamping grooves 43 are arranged in pairs on the inner wall of the fixing cover 41, and the connecting line between the two fixing claws 42 and the connecting line between the two T-blocks 55 are intertwined with each other; the inner wall of the storage groove 51 is provided with a matching groove that matches the end of the fixing claw 42, and the matching groove is engaged with the end of the fixing claw 42, and the fixing cover 41 on the cover can fix the electrode lead 3 inside the storage groove 51.

[0028] It should be noted that when the utility model is in use, one end of the electrode lead 3 is connected to the winding inside the motor housing 1. The winding is prone to friction with the relatively loose electrode lead 3, which causes the electrode lead 3 to be worn and affects the use of the motor housing 1. At this time, the other end of the electrode lead 3 can be connected to the terminal on the terminal box 2, and the redundant wire in the middle of the electrode lead 3 is wound between the two T-blocks 55, so that the two T-blocks 55 are close to the middle of the storage groove 51, so that the two T-blocks 55 wind the electrode lead 3, and the electrode lead 3 is wound between the two groups of reserved openings 56. The electrode lead 3 wound at the two groups of reserved openings 56 is not easy to fall off, avoiding redundant wires. The long electrode lead 3 contacts the end surface of the winding and thus wears out, and can be moved toward both ends along the connecting rod 53 by the telescopic spring 54 against the two T-blocks 55, thereby changing the spacing between the two T-blocks 55, so that the slack electrode lead 3 is gradually tightened, thereby further avoiding the friction between the lead and the winding caused by being too long; after completing the wiring and winding of the electrode lead 3, the fixing cover 41 of the clamping structure 4 can be covered on the storage groove 51, and the electrode lead 3 wound between the two T-blocks 55 can be clamped by two fixing claws 42 to prevent the electrode lead 3 from falling off between the T-blocks 55, thereby ensuring that the electrode lead 3 will not be worn out and the motor can operate normally.
