Description

Technical Field

[0001] This invention belongs to the technical field of motor accessories, specifically a novel structure for fixing the winding leads of a high-voltage motor. Background Technology

[0002] Stator windings refer to the windings installed on the stator, which are copper wires wound on the stator. A winding is a general term for a phase or the entire electromagnetic circuit composed of multiple coils or coil groups. According to the different shapes of the coil windings and the embedding and wiring methods, motors can be divided into two categories: concentrated windings and distributed windings.

[0003] In existing technologies, when fixing the winding leads, the leads drawn from the winding are fixed by soldering. However, the soldering process is relatively complicated, the connection strength is not high, and the leads are prone to falling off when subjected to external tension. It is also difficult to re-solder the leads after they fall off. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, and to address the issue that in existing technologies, the leads are fixed by soldering, which is a complex process with low connection strength, and the leads are prone to detachment when subjected to external tension, making re-soldering difficult after the leads fall off.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: A novel structure for fixing the winding lead of a high-voltage motor, comprising a lead body, a housing, and a fixing plate; a motor end cover is fixedly connected to the bottom of the housing, and a pair of inlet holes are provided at its bottom; the fixing plate is fixedly connected to the inner wall of the housing and is mirror-image of the central axis of the housing, and has a first cavity and a fixing assembly inside; an opening is provided on the inner wall of the bottom end of the first cavity; a connecting terminal is fixedly connected to the end of the lead body and passes through the inlet hole and the opening; the connecting terminal is sleeved on the fixing assembly; the fixing assembly includes a straight rod, a transmission mechanism, and a fixing rod; the straight rod is rotatably connected to the inner wall of the fixing plate, and a first bevel gear is fixedly connected to one end of it; the transmission mechanism is disposed inside the first cavity and meshes with the first bevel gear; the fixing rod is fixedly connected to the inner wall of the bottom end of the first cavity. The connecting terminal is sleeved on the outer wall of the fixing rod. During operation, when fixing the winding leads inside the motor, the lead body is led out from the end cover of the non-power output end of the motor. The end of the lead body is fixed with a connecting terminal. The connecting terminal and the lead body are passed through the inlet hole at the bottom of the housing and the opening at the bottom of the fixing plate, so that the connecting terminal is sleeved on the outer wall of the fixing rod. At this time, the connecting terminal is pressed and the straight rod is twisted, so that the straight rod rotates. The straight rod drives the first bevel gear to rotate, and the first bevel gear meshes with the second bevel gear, so that the first bevel gear drives the second bevel gear and the lead screw to rotate. A slider is sleeved on the outer wall of the lead screw. The slider and the lead screw are connected by a ball screw nut pair. During the rotation of the lead screw, the slider slides down, so that the side wall of the slider presses the connecting terminal, thereby fixing the connecting terminal and the lead body.

[0006] Preferably, the transmission mechanism includes a second bevel gear, a lead screw, and a slider; the lead screw is rotatably connected to the inner wall of the bottom end of the first cavity; the second bevel gear is fixed to the end of the lead screw and meshes with the first bevel gear; the slider is sleeved on the outer wall of the lead screw, connected to the lead screw by a ball screw nut pair, and slidably engaged with the inner wall of the first cavity, and has a through hole at its top; the fixing rod is slidably engaged with the inner wall of the through hole; during operation, when the connecting terminal is pressed, the cylindrical block is twisted, causing the straight rod to rotate, which drives the first bevel gear to rotate, and the first bevel gear meshes with the second bevel gear, thereby causing the first bevel gear to drive the second bevel gear and the lead screw to rotate. The slider is sleeved on the outer wall of the lead screw, and the slider is connected to the lead screw by a ball screw nut pair. During the rotation of the lead screw, the slider slides down, and during the gradual slide of the slider, it presses the connecting terminal sleeved on the outer wall of the fixing rod, thereby fixing the connecting terminal. Furthermore, during the slide of the slider, the fixing rod is inserted into the through hole, thereby fixing the slider and improving the fixing effect of the connecting terminal.

[0007] Preferably, a first groove is provided on the inner sidewall of the inlet hole; a second groove is provided at the top of the first groove; a clamping mechanism is provided inside the bottom sidewall of the housing; the clamping mechanism includes a sliding plate, a push plate, and a connecting rod; the sliding plate is slidably connected to the second groove by a spring, and its top is connected to the sidewall of the slider by a thin rope; the push plate is slidably connected to the first groove; one end of the connecting rod is hinged to the sidewall of the push plate, and the other end is hinged to the bottom of the sliding plate; during operation, before the lead wire body is inserted into the inlet hole, the spring at the top of the sliding plate is in a stretched state, and the push plate blocks the inlet hole, at which time the inlet hole is in a closed state. At this time, rotating the cylindrical block causes the straight rod to rotate, which drives the first bevel gear to rotate, and the first bevel gear meshes with the second bevel gear, thereby causing the first bevel gear to drive the second bevel gear and the lead screw to rotate. A slider is fitted on the outer wall of the lead screw, and the slider is connected to the lead screw via a ball screw nut pair. During the rotation of the lead screw, the slider is driven to slide upward. During the upward movement of the slider, a thin rope pulls the slide plate upward, thereby compressing the spring. During the upward movement of the slide plate, a connecting rod pulls the push plate to slide into the first groove, opening the inlet hole and allowing the connecting terminal to be fitted onto the fixed rod. At this time, the cylindrical rod is rotated in the opposite direction, causing the slider to slide downward, thereby pressing and fixing the connecting terminal. During the downward movement of the slider, the spring rebounds, causing the slide plate to slide down along the inner wall of the second groove, pressing the lead wire body against the inner wall of the inlet hole. This provides support and compression for the lead wire body, reducing the stress on the connection between the lead wire body and the connecting terminal, thus making the connection between the lead wire body and the connecting terminal more stable.

[0008] Preferably, the bottom sidewall of the housing has a second cavity; an oil bladder is fixedly connected inside the second cavity; an oil nozzle is fixedly connected to the inner sidewall of the top of the first cavity; the oil nozzle communicates with the inside of the oil bladder; a push rod is fixedly connected to the sidewall of the push plate; the push rod contacts the oil bladder; during operation, when the push plate slides into the first groove, it drives the push rod to slide, causing the push rod to squeeze the oil bladder, and the lubricating oil inside the oil bladder is pressurized and sprayed out from the oil nozzle, dripping onto the first bevel gear, thereby lubricating the first bevel gear. During the meshing process between the first bevel gear and the second bevel gear, the second bevel gear is also lubricated, thereby reducing the wear of the first bevel gear and the second bevel gear and improving their service life.

[0009] Preferably, a first magnetic sheet is fixedly connected to the side wall of the slider; a second magnetic sheet is fixedly connected to the inner side wall of the bottom end of the first cavity; the second magnetic sheet and the first magnetic sheet are located on the same axis and have opposite magnetic properties; during operation, as the slider gradually slides down, the distance between the first magnetic sheet and the second magnetic sheet gradually decreases, and since the first magnetic sheet and the second magnetic sheet have opposite magnetic properties, the first magnetic sheet and the second magnetic sheet attract each other. When the slider presses the connecting terminal, the magnetic force between the first magnetic sheet and the second magnetic sheet plays an auxiliary role in fixing the connecting terminal, making the pressing and fixing effect better.

[0010] Preferably, a power terminal is fixedly connected to the outer wall of the housing; multiple rubber protrusions are fixedly connected to the side wall of the push plate opposite to the connecting rod; a cylindrical block is fixedly connected to the end of the straight rod away from the first bevel gear; and an anti-slip groove is provided on the side wall of the cylindrical block. During operation, when the push plate presses the lead body, the rubber protrusions increase the friction between the push plate and the side wall of the lead body, thereby supporting the lead body and reducing the stress at the connection between the lead body and the connecting terminal, thus making the fixation of the lead body more stable. The anti-slip groove on the side wall of the cylindrical block increases the friction between the hand and the side wall of the cylindrical block, thus making the cylindrical block better bear the force.

[0011] The beneficial effects of this invention are as follows:

[0012] 1. The present invention discloses a novel structure for fixing the winding lead of a high-voltage motor. Through the coordinated operation of a cylindrical block, a straight rod, a first bevel gear, a second bevel gear, a lead screw, a slider, a fixing rod, and a connecting terminal, the lead body is clamped and fixed, preventing the lead body from falling off when the motor is working, thereby enabling the motor to operate better.

[0013] 2. In this invention, when the push plate slides into the first groove, it drives the push rod to squeeze the oil bladder. The lubricating oil inside the oil bladder is pressurized and sprayed out from the oil nozzle, dripping onto the first bevel gear, thereby lubricating the first bevel gear. During the meshing process between the first bevel gear and the second bevel gear, the second bevel gear is also lubricated, thereby reducing the wear of the first bevel gear and the second bevel gear and improving the performance of the device.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5As shown, the present invention discloses a novel structure for fixing high-voltage motor winding leads, comprising a lead body 1, a housing 2, and a fixing plate 3; a motor end cover 21 is fixedly connected to the bottom of the housing 2, and a pair of wire inlet holes 22 are provided at its bottom; the fixing plate 3 is fixedly connected to the inner wall of the housing 2 and is mirror-image of the central axis of the housing 2, and has a first cavity 31 and a fixing assembly 4 inside; the inner wall of the bottom end of the first cavity 31 has an opening 32; a connecting terminal 11 is fixedly connected to the end of the lead body 1. It passes through the inlet hole 22 and the opening 32; the connecting terminal 11 is sleeved on the fixing component 4; the fixing component 4 includes a straight rod 41, a transmission mechanism 42 and a fixing rod 43; the straight rod 41 is rotatably connected to the inner wall of the fixing plate 3, and one end of it is fixedly connected to a first bevel gear 411; the transmission mechanism 42 is disposed inside the first cavity 31 and meshes with the first bevel gear 411; the fixing rod 43 is fixedly connected to the inner wall of the bottom end of the first cavity 31; the connecting terminal 11 is sleeved on the outside of the fixing rod 43. On the wall; during operation, when fixing the winding leads inside the motor, the lead body 1 is led out from the end cover of the non-power output end of the motor. The end of the lead body 1 is fixed with a connecting terminal 11. The connecting terminal 11, together with the lead body 1, is passed through the inlet hole 22 at the bottom of the housing 2 and the opening 32 at the bottom of the fixing plate 3, so that the connecting terminal 11 is sleeved on the outer wall of the fixing rod 43. At this time, the connecting terminal 11 is pressed tight, and the straight rod 41 is twisted to make the straight rod 41 rotate. The straight rod 41 drives the first bevel tooth. When wheel 411 rotates, the first bevel gear 411 meshes with the second bevel gear 421, thereby causing the first bevel gear 411 to drive the second bevel gear 421 and the lead screw 422 to rotate. A slider 423 is sleeved on the outer wall of the lead screw 422. The slider 423 and the lead screw 422 are connected by a ball screw nut pair. During the rotation of the lead screw 422, the slider 423 is driven to slide down, so that the side wall of the slider 423 presses against the connecting terminal 11, thereby fixing the connecting terminal 11 and the lead wire body 1.

[0023] In one embodiment of the present invention, the transmission mechanism 42 includes a second bevel gear 421, a lead screw 422, and a slider 423; the lead screw 422 is rotatably connected to the inner wall of the bottom end of the first cavity 31; the second bevel gear 421 is fixedly connected to the end of the lead screw 422 and meshes with the first bevel gear 411; the slider 423 is sleeved on the outer wall of the lead screw 422, is connected to the lead screw 422 as a ball screw nut pair, slides with the inner wall of the first cavity 31, and has a through hole 424 at its top; the fixed rod 43 slides with the inner wall of the through hole 424; during operation, when the connecting terminal 11 is pressed, the cylindrical block 412 is twisted, causing the straight rod 41 to rotate, and the straight rod 41 drives the first bevel gear. 411 rotates, and the first bevel gear 411 meshes with the second bevel gear 421, thereby causing the first bevel gear 411 to drive the second bevel gear 421 and the lead screw 422 to rotate. A slider 423 is sleeved on the outer wall of the lead screw 422. The slider 423 and the lead screw 422 are connected by a ball screw nut pair. During the rotation of the lead screw 422, the slider 423 is driven to slide down. During the gradual slide down, the slider 423 presses against the connecting terminal 11 sleeved on the outer wall of the fixing rod 43, thereby fixing the connecting terminal 11. During the slide down, the fixing rod 43 is inserted into the through hole 424, thereby fixing the slider 423 and making the fixing effect of the connecting terminal 11 better.

[0024] In one embodiment of the present invention, a first groove 23 is provided on the inner sidewall of the inlet hole 22; a second groove 24 is provided at the top of the first groove 23; a clamping mechanism 5 is provided inside the bottom sidewall of the housing 2; the clamping mechanism 5 includes a sliding plate 51, a push plate 52, and a connecting rod 53; the sliding plate 51 is slidably connected to the second groove 24 by a spring, and its top is connected to the sidewall of the slider 423 by a thin rope; the push plate 52 is slidably connected to the first groove 23; one end of the connecting rod 53 is hinged to the push plate 52. On the side wall of plate 52, the other end is hinged to the bottom of slide plate 51; during operation, before inserting the lead wire body 1 into the inlet hole 22, the spring at the top of slide plate 51 is in a stretched state, and push plate 52 blocks the inlet hole 22, at which time the inlet hole 22 is in a closed state. At this time, rotating cylindrical block 412 causes straight rod 41 to rotate, and straight rod 41 drives first bevel gear 411 to rotate. Then, first bevel gear 411 meshes with second bevel gear 421, thereby causing first bevel gear 411 to drive second bevel gear 421 to engage with the lead wire. The rod 422 rotates, and a slider 423 is sleeved on the outer wall of the lead screw 422. The slider 423 and the lead screw 422 are connected by a ball screw and nut pair. During the rotation of the lead screw 422, the slider 423 is driven to slide upward. During the upward sliding of the slider 423, the slide plate 51 is pulled upward by the thin rope, thereby compressing the spring. During the upward sliding of the slide plate 51, the push plate 52 is pulled into the first slide groove 23 by the connecting rod 53, so that the wire inlet hole 22 is opened, thereby allowing the connecting terminal 11 to be sleeved on the fixed rod 43. At this time, the cylindrical rod is rotated in the opposite direction, causing the slider 423 to slide down, thereby pressing and fixing the connecting terminal 11. During the sliding of the slider 423, the spring rebounds, causing the slide plate 51 to slide down along the inner wall of the second slide groove 24, so that the push plate 52 presses the lead wire body 1 against the inner wall of the inlet hole 22, thereby supporting and pressing the lead wire body 1, reducing the force on the connection between the lead wire body 1 and the connecting terminal 11, and making the connection between the lead wire body 1 and the connecting terminal 11 more stable.

[0025] In one embodiment of the present invention, a second cavity 25 is provided inside the bottom sidewall of the housing 2; an oil bladder 251 is fixedly connected inside the second cavity 25; an oil nozzle 311 is fixedly connected to the inner sidewall of the top of the first cavity 31; the oil nozzle 311 communicates with the inside of the oil bladder 251; a push rod 521 is fixedly connected to the sidewall of the push plate 52; the push rod 521 contacts the oil bladder 251; during operation, when the push plate 52 slides towards the inside of the first sliding groove 23, it drives the push rod 521 to slide, causing the push rod 521 to squeeze the oil bladder 251, and the lubricating oil inside the oil bladder 251 is pressurized and sprayed out from the oil nozzle 311 and drips onto the first bevel gear 411, thereby lubricating the first bevel gear 411. During the meshing process between the first bevel gear 411 and the second bevel gear 421, the second bevel gear 421 is lubricated, thereby reducing the wear of the first bevel gear 411 and the second bevel gear 421 and improving their service life.

[0026] In one embodiment of the present invention, a first magnetic sheet 425 is fixedly connected to the side wall of the slider 423; a second magnetic sheet 312 is fixedly connected to the inner side wall of the bottom end of the first cavity 31; the second magnetic sheet 312 and the first magnetic sheet 425 are located on the same axis and have opposite magnetic properties; during operation, as the slider 423 gradually slides down, the distance between the first magnetic sheet 425 and the second magnetic sheet 312 gradually decreases, and since the first magnetic sheet 425 and the second magnetic sheet 312 have opposite magnetic properties, the first magnetic sheet 425 and the second magnetic sheet 312 attract each other. When the slider 423 presses the connecting terminal 11, the magnetic force between the first magnetic sheet 425 and the second magnetic sheet 312 plays an auxiliary role in fixing the connecting terminal 11, making the pressing and fixing effect better.

[0027] In one embodiment of the present invention, a power terminal 26 is fixedly connected to the outer wall of the housing 2; multiple rubber protrusions 522 are fixedly connected to the side wall of the push plate 52 opposite to the connecting rod 53; a cylindrical block 412 is fixedly connected to the end of the straight rod 41 away from the first bevel gear 411; an anti-slip groove 413 is provided on the side wall of the cylindrical block 412; during operation, when the push plate 52 presses the lead body 1, the rubber protrusions 522 increase the friction between the push plate 52 and the side wall of the lead body 1, thereby supporting the lead body 1 and reducing the stress at the connection between the lead body 1 and the connecting terminal 11, thus making the fixation of the lead body 1 more stable; the anti-slip groove 413 on the side wall of the cylindrical block 412 increases the friction between the hand and the side wall of the cylindrical block 412, thereby making the cylindrical block 412 better bear the force.

[0028] Working principle: Before inserting the lead wire body 1 into the inlet hole 22, the spring at the top of the slide plate 51 is in a stretched state, and the push plate 52 blocks the inlet hole 22, so the inlet hole 22 is in a closed state. At this time, rotating the cylindrical block 412 causes the straight rod 41 to rotate. The anti-slip groove 413 on the side wall of the cylindrical block 412 increases the friction between the hand and the side wall of the cylindrical block 412, making the cylindrical block 412 better bear the force. The straight rod 41 drives the first bevel gear 411 to rotate, and the first bevel gear 411 meshes with the second bevel gear 421, thereby driving the second bevel gear 421 and the lead screw 422 to rotate. A slider 423 is sleeved on the outer wall of the lead screw 422. The slider 423 and the lead screw 422 are connected by a ball screw nut pair. When the lead screw 422 rotates... During the process, the slider 423 is driven to slide upward. As the slider 423 slides upward, the thin rope pulls the slide plate 51 upward, compressing the spring. During the upward sliding of the slide plate 51, the connecting rod 53 pulls the push plate 52 towards the inside of the first groove 23, opening the inlet hole 22 and allowing the connecting terminal 11 to be smoothly fitted onto the fixing rod 43. As the push plate 52 slides towards the inside of the first groove 23, it drives the push rod 521 to slide, causing the push rod 521 to squeeze the oil bladder 251. The lubricating oil inside the oil bladder 251 is pressurized and sprayed from the nozzle 311, dripping onto the first bevel gear 411, thus lubricating the first bevel gear 411. During the meshing process between the first bevel gear 411 and the second bevel gear 421, the second bevel gear 421... 1. Lubrication is performed to reduce wear on the first bevel gear 411 and the second bevel gear 421, thereby improving their service life. At this time, the cylindrical rod is rotated in the opposite direction, causing the slider 423 to slide down. During the gradual descent of the slider 423, the connecting terminal 11 sleeved on the outer wall of the fixing rod 43 is pressed, thereby fixing the connecting terminal 11. During the descent of the slider 423, the fixing rod 43 is inserted into the through hole 424, thereby fixing the slider 423 and improving the fixing effect of the connecting terminal 11. During the gradual descent of the slider 423, the spring rebounds, causing the slide plate 51 to slide down along the inner wall of the second slide groove 24, causing the connecting rod 53 to press the push plate 52, thereby pressing the lead wire body 1 into the inlet hole 2. On the inner wall of 2, the rubber protrusion 522 increases the friction between the push plate 52 and the side wall of the lead body 1, thereby supporting the lead body 1 and reducing the stress at the connection between the lead body 1 and the connecting terminal 11, thus making the connection between the lead body 1 and the connecting terminal 11 more stable. As the slider 423 gradually slides down, the distance between the first magnetic sheet 425 and the second magnetic sheet 312 gradually decreases. Since the first magnetic sheet 425 and the second magnetic sheet 312 have opposite magnetic properties, they attract each other. When the slider 423 presses the connecting terminal 11, the magnetic force between the first magnetic sheet 425 and the second magnetic sheet 312 assists in fixing the connecting terminal 11, making the pressing and fixing effect better.
