Description

Technical Field

[0001] The invention belongs to the technical field of motors, and in particular relates to a motor terminal block capable of reducing the shedding of a wire harness. Background Art

[0002] The motor is an indispensable part of today's production and life. It is mainly composed of a casing, a stator, a rotor and a terminal block. The terminal block is responsible for connecting the stator winding in the stator and the cable conducting to the outside world so that the motor can work under the drive of electric current.

[0003] As an indispensable part of mechanical processing, three-phase motors are widely used in industrial production. Existing industrial equipment places the motor inside the equipment for reasons such as dust prevention and aesthetics. This practice makes it impossible to observe the motor intuitively. During the long-term operation of the existing motor, the wiring part of the motor will generate heat and cause the aging speed to accelerate, making it more susceptible to corrosion. During the operation of the motor, it will vibrate. This means that when the wiring part is aged and corroded due to long-term use, the wiring part will break due to the vibration when the motor is working, causing the motor to lose energy and gradually stop. At this time, the processing performed by the equipment during the motor stoppage cannot guarantee its processing quality, resulting in production accidents. At the same time, the motor needs to be repaired, wasting production time. Summary of the invention

[0030] 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.

[0031] like Figures 1 to 12As shown, an embodiment of the present invention provides a terminal block for a motor that reduces the shedding of a wiring harness, comprising a shell 1 and an upper cover 2, the upper cover 2 being fixedly connected to the top surface of the shell 1, the side of the shell 1 being fixedly sleeved with a main cable 3 and a secondary cable 4, the interior of the shell 1 being clamped with a partition 8, the side of the partition 8 close to the main cable 3 being provided with a plurality of first sliding grooves 9, the interior of the shell 1 being fixedly connected with a plurality of first terminals 12 and second terminals 13, the first terminals 12 and the second terminals 13 being located on both sides of the partition 8, a group of first terminals 12 and second terminals 13 being electrically connected via a connecting piece 14, the connecting piece 14 being located below the partition 8, the outer surfaces of the first terminals 12 and the second terminals 13 being fixedly sleeved with an insulating The outer surface of the first terminal 12 is fixedly connected with a conductive ring 16 and an insulating sleeve 21, the outer surface of the conductive ring 16 is movably connected with a lower conductive plate 17, the outer surface of the insulating sleeve 21 is movably connected with an upper conductive plate 19, the outer side of the lower conductive plate 17 is fixedly connected with a symmetrical lower clamping plate 18, the outer side of the upper conductive plate 19 is fixedly connected with a symmetrical upper clamping plate 20, the outer surfaces of the plurality of first terminals 12 are commonly connected with a limit plate 23, the limit plate 23 is located between the lower clamping plate 18 and the upper clamping plate 20, teeth 24 are provided at both ends of the limit plate 23, a symmetrical guide column 25 is fixedly connected to one side of the limit plate 23, an oblique opening 26 is provided on the side of the guide column 25, and an inclined surface is provided on the bottom surface of the guide column 25.

[0032] During the use of the motor, heat will be generated between the wiring part of the cable and the motor terminal due to the current conduction, which will accelerate the aging of the cable terminal. At the same time, the vibration generated when the motor is working will also make the wiring part of the cable more prone to damage and breakage. Once the wiring part of the cable is damaged and broken during the processing, the motor will stop due to loss of energy. At this time, the equipment processing process will be interrupted, causing problems in the production process and wasting production time. If the equipment uses multiple motors to work together, problems with the cable of a single motor will cause damage to the workpiece in production, thereby causing a waste of funds.

[0033] The terminal block of the present invention can not only reduce the damage to the wiring part caused by the vibration of the cable during the use of the motor, but also during the processing, once it is found that the motor stops working due to the damage of the wiring part, it only needs to push the pressure plate 28 downward to change the motor circuit from being connected with the main cable 3 to being connected with the auxiliary cable 4, thereby preventing property losses caused by direct shutdown. At the same time, the working light 5 and the emergency light 6 on the side of the shell 1 can enable the staff to intuitively understand the connectivity of the internal circuits of the terminal block, thereby improving the maintenance efficiency.

[0034] like Figures 4 to 6As shown, a second slide groove 30 is provided inside the housing 1, and a first slider 31 is slidably connected inside the second slide groove 30. A third spring 32 is elastically connected between the first slider 31 and the inner side surface of the second slide groove 30. An inclined sliding surface is provided at the front end of the first slider 31, and the inclined sliding surface is parallel to the inclined surface provided at the bottom of the guide column 25 and the inclined surface of the inclined opening 26.

[0035] After the limit plate 23 moves downward, the guide column 25 moves downward synchronously, so that the guide column 25 pushes the first slider 31 to slide into the second slide groove 30. As the bottom surface of the guide column 25 contacts the inner bottom surface of the second slide groove 30, the first slider 31 is pushed by the third spring 32 to move outward and get stuck in the inclined opening 26, preventing the guide column 25 and the limit plate 23 from moving upward, so that the limit plate 23 remains stable, and then the lower clamping plate 18 and the upper clamping plate 20 remain stable.

[0036] like Figure 5 and Fig.10 As shown, the inner side surface of the shell 1 fixedly sleeved with the main cable 3 is provided with a plurality of guide grooves 44, and a symmetrical third groove 33 and a transverse groove 46 are provided inside the same side surface, the transverse groove 46 is communicated with the interior of the shell 1, the third groove 33 is communicated with the transverse groove 46, the inner top surface of the third groove 33 is provided with a fourth groove 34, the top of the fourth groove 34 is communicated with the outside, the interior of the third groove 33 is slidably connected with a driving bevel block 35, the top surface of the driving bevel block 35 is fixedly connected with a sliding rod 36, the sliding rod 36 is located in the fourth groove 34, the outer surface of the sliding rod 36 is fixedly sleeved with a limiting ring 37, and a fourth spring 38 is elastically connected between the bottom surface of the limiting ring 37 and the inner bottom surface of the fourth groove 34.

[0037] After the upper cover 2 is installed on the top of the outer shell 1, the upper cover 2 will drive the sliding rod 36 to move downward, so that the sliding rod 36 drives the driving bevel block 35 to move downward, so that the driving bevel blocks 35 on both sides push the two passive bevel blocks 39 to move toward each other, and then the driving bevel blocks 35 can drive the fastening clamps 42 to clamp the main cable 3 and the auxiliary cable 4, so as to prevent the main cable 3 and the auxiliary cable 4 from shaking during the operation of the motor and causing the wiring part to fall off, and the wear and damage caused by frequent friction between the cable sheath and the socket of the outer shell 1.

[0038] like Figures 2 to 6 as well as Fig.10As shown, the interior of the transverse slide groove 46 is slidably connected with a passive inclined block 39, and the side of the passive inclined block 39 is fixedly connected with a connecting plate 40, and the opposite surfaces of the connecting plate 40 are fixed with two connecting slide rods 41, and the connecting slide rods 41 are slidably connected in the sliding seat on the inner side of the shell 1, and a fifth spring 45 is elastically connected between the connecting plate 40 and the opposite side of the sliding seat, and one end of the connecting slide rod 41 is fixedly connected with a fastening clamp 42, and the side of the fastening clamp 42 close to the inner side of the shell 1 is fixedly connected with a plurality of slide columns 43, and the slide columns 43 are slidably connected to the inside of the guide slide groove 44.

[0039] The passive inclined blocks 39 on both sides move toward each other after being pushed by the driving inclined blocks 35, thereby driving the tightening clamps 42 to move toward each other, so that the tightening clamps 42 on both sides clamp the main cable 3 or the auxiliary cable 4 in the middle, preventing the main cable 3 and the auxiliary cable 4 from being worn at the cable sheath and the socket joint due to the vibration generated during the operation of the motor, thereby extending the service life of the main cable 3 and the auxiliary cable 4.

[0040] like Figures 2 to 10 As shown, a plurality of connecting rods 27 are fixedly connected to the upper surface of the limiting plate 23, the top ends of the connecting rods 27 pass through the top of the upper cover 2 and are fixedly connected to a pressing plate 28, and the limiting plate 23, the connecting rods 27 and the pressing plate 28 are all made of insulating materials.

[0041] The pressure plate 28 is located above the upper cover 2. When the main cable 3 is aged, corroded, or the like, causing the line to be disconnected, the circuit can be switched to the auxiliary cable 4 and the line only by pushing the pressure plate 28 downward, thereby preventing property losses caused by the motor stopping during processing. At the same time, the limit plate 23, connecting rod 27 and pressure plate 28 made of insulating material can prevent electric shock.

[0042] like Figures 2 to 8 As shown, two symmetrical receiving grooves are opened inside the housing 1, and a rack 10 is slidably connected in the receiving groove. A plurality of first springs 11 are elastically connected between the rack 10 and the opposite side of the receiving groove, and the rack 10 and the teeth 24 are engaged with each other.

[0043] After a failure occurs in the main cable 3 causing the circuit to be disconnected, the pressure plate 28 is pushed downward and drives the limit plate 23 to move downward. After the limit plate 23 moves downward, the teeth 24 on both sides of the limit plate 23 will push the rack 10 to move to both sides. Then, the rack 10 is re-engaged with the teeth 24 under the action of the first spring 11 and prevents the limit plate 23 from moving upward, preventing the limit plate 23 from being driven upward by the second spring 22 after switching from the main cable 3 to the auxiliary cable 4, causing the auxiliary cable 4 to be disconnected again, resulting in property losses caused by the motor stopping during processing.

[0044] like Figures 2 to 8As shown, one end of the lower clamping plate 18 and the upper clamping plate 20 are slidably connected in the first slide groove 9, and the lower conductive plate 17 and the upper conductive plate 19 are fixedly connected to the end close to the main cable 3 with a terminal 29, and the terminal 29 is connected to a single wiring harness of the main cable 3 and the auxiliary cable 4 to complete the circuit.

[0045] The lower clamping plate 18 and the upper clamping plate 20 will rotate slightly due to the vibration of the motor during operation. After a long period of accumulation, they will produce a larger displacement, causing the wiring harness connected to the terminal 29 to be pulled, causing the conductor in the wiring harness to be stretched. Long-term stretching will cause the conductor to become thinner and easy to break. At the same time, the conductor is more likely to break under the vibration of the motor. Fixing one end of the lower clamping plate 18 and the upper clamping plate 20 to prevent them from rotating can extend the service life of the wiring harness, thereby ensuring the service life of the motor.

[0046] like Figures 1 to 4 As shown, a circuit box 7 is fixedly installed inside the housing 1, an iron core is fixedly installed inside the fastening clamp 42, the bottom end of the fastening clamp 42 is electrically connected to the circuit box 7, the fastening clamp 42 on the side of the main cable 3 is electrically connected to the working light 5 through the circuit box 7, and the fastening clamp 42 on the side of the auxiliary cable 4 is electrically connected to the emergency light 6 through the circuit box 7.

[0047] According to Ampere's force law, when current flows through the cable, a magnetic field will be generated around the cable. At this time, the magnetic field passes through the iron core in the fastening clamp 42 and is captured by the circuit box 7 electrically connected to the fastening clamp 42, and controls the work light 5 or the emergency light 6 to light up. At this time, the staff only needs to observe the lighting status of the work light 5 or the emergency light 6 to respond. If the work light 5 is found to be extinguished during the processing, it is only necessary to push the pressure plate 28 downward to switch to the auxiliary cable 4 to support the completion of the current processing and prevent property loss.

[0048] like Figures 8 to 9 As shown, the limiting plate 23 is fixedly connected to the lower clamping plate 18 and the upper clamping plate 20 , and a second spring 22 is elastically connected between the bottom surface of the lower clamping plate 18 and the top surface of the insulating pad 15 .

[0049] After moving downward, the limit plate 23 can drive the lower clamping plate 18 and the upper clamping plate 20 fixedly connected thereto to move downward, so that after pushing the pressure plate 28 downward, the passage between the first terminal 12 and the lower conductive plate 17 is switched to the passage between the first terminal 12 and the upper conductive plate 19, so that the device can quickly switch to the auxiliary cable 4 when there is a problem with the connection of the main cable 3, preventing the motor from suddenly losing power during operation and causing raw material loss. The setting of the second spring 22 prevents the limit plate 23 from being mistriggered due to spontaneous downward displacement under the action of its own weight and motor vibration.

[0050] Working principle:

[0051] When installing this equipment, first use the connecting piece 14 to connect the corresponding first terminal 12 with the second terminal 13, so that the stator winding is connected to the first terminal 12, then put the partition 8 into the outer shell 1, so that the first slide groove 9 faces the first terminal 12, and then put the insulating pad 15 on the first terminal 12 and the second terminal 13, and then tighten the nut on the second terminal 13 to prevent the insulating pad 15 thereon from falling off due to the vibration of the motor operation.

[0052] Then, the second spring 22 is sleeved on the first terminal 12 so that it is located on the insulating pad 15 sleeved on the first terminal 12, and then the conductive ring 16 is fixed on the first terminal 12, and the lower conductive plate 17 is sleeved on the conductive ring 16, and then the lower clamping plate 18 is fixed on both sides of the lower conductive plate 17, and one end of the lower clamping plate 18 is slidably connected in the first slide groove 9, and then the limiting plate 23 is sleeved on the first terminal 12, and the limiting plate 23 and the lower clamping plate 18 are fixed to each other, and then the insulating sleeve 21 is sleeved on the first terminal 12 so that it is located above the conductive ring 16, and then the upper conductive plate 19 is sleeved on the outside of the insulating sleeve 21, and then the upper clamping plate 20 is fixed on both sides of the upper conductive plate 19 and the upper clamping plate 20 is fixed to the limiting plate 23, and then the terminal head 29 is connected to the lower conductive plate 17 and one end of the upper conductive plate 19 through bolts and other parts. At this time, there is no conduction between the upper conductive plate 19 and the conductive ring 16.

[0053] Then, the main cable 3 and the auxiliary cable 4 are passed through the side of the shell 1, and the wiring harness in the cable is connected to the terminal head 29. Then, the upper cover 2 is installed on the top of the shell 1. The upper cover 2 will push the sliding rod 36 to move downward, thereby moving the driving bevel block 35 downward. Then, the passive bevel blocks 39 on both sides will move toward each other under the push of the driving bevel block 35, driving the fastening clamps 42 on both sides to approach. As the fastening clamps 42 on both sides are closed, the main cable 3 and the auxiliary cable 4 are clamped.

[0054] When the motor is working, the main cable 3 is energized, and the clamping clamp 42 clamping the main cable 3 transmits the received magnetic field signal to the circuit box 7, and the circuit box 7 controls the working light 5 to turn on and the emergency light 6 to turn off. When the main cable 3 fails (such as the wiring harness of the main cable 3 is separated from the terminal head 29 or the terminal head 29 is corroded and disconnected from the first terminal 12), the pressure plate 28 is pushed downward, and the lower conductive plate 17 is disconnected from the conductive ring 16, and the upper conductive plate 19 is connected to the conductive ring 16. The clamping clamp 42 clamping the auxiliary cable 4 transmits the received magnetic field signal to the circuit box 7, and the circuit box 7 controls the working light 5 to turn off and the emergency light 6 to turn on.

[0055] When the upper cover 2 is opened, the fourth spring 38 drives the sliding rod 36 to move upward, and the fifth spring 45 drives the connecting plate 40 to move in the direction of the main cable 3, so that the staff can quickly replace the damaged main cable 3.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
