Description

Technical Field

[0001] This invention belongs to the field of thermal protector testing technology, specifically a thermal protector testing device. Background Technology

[0002] A thermal protector is an electrical component used to protect circuit equipment from burnout due to prolonged overcurrent. The core component of a thermal protector is a bimetallic strip. When current flows through this strip, it heats up. Because the two different alloys have different coefficients of thermal expansion, the bimetallic strip bends in one direction, moving away from the conductive contact, thus cutting off the circuit and protecting the equipment. The working principle of currently used thermal protectors is that the current flowing into the heating element generates heat, causing the bimetallic strip with different coefficients of thermal expansion to deform. When the deformation reaches a certain distance, it pushes a linkage, disconnecting the control circuit, thereby de-energizing the contactor, disconnecting the main circuit, and achieving overload protection for the motor.

[0003] The existing method for testing the trip temperature of thermal protectors involves connecting the two wires of the thermal protector to a circuit, placing the thermal protector inside an oven, and raising the oven temperature at a specified rate. The trip temperature of the thermal protector is detected by monitoring the continuity of the circuit. When the thermal protector disconnects the circuit, the real-time temperature inside the oven is the trip temperature. This method is inefficient in temperature detection. Each test requires connecting the two wires of the thermal protector to a special clamp, which is cumbersome. Furthermore, each test requires raising the oven temperature from low to high and lowering it afterward, which is time-consuming. Summary of the Invention

[0028] The second wire is disposed on the outer wall of the drive seat near the power supply side, and the other end of the second wire is connected to the power supply.

[0029] The circuit connection path of the device is as follows: from the second wire to the connecting wire, then to the light bulb, then in series with the thermal protector element, and finally from the second wire to the power supply, so that the light bulb and the thermal protector element are connected in series, so that the current flows in from the first wire and flows out from the second wire.

[0030] Furthermore, the guiding component includes:

[0031] The slider is symmetrically arranged on the top of the drive seat, and the bottom of the slider is slidably connected to the top of the drive seat;

[0032] A bracket is disposed on top of the slider;

[0033] A collar, the inner wall of which is fitted onto the outer wall of the bracket.

[0034] Furthermore, the guiding component also includes:

[0035] Extrusion rods are evenly distributed on the outer wall of the collar;

[0036] An elastic ring is installed at the end of the extrusion rod away from the collar.

[0049] The beneficial effects of this invention are as follows:

[0050] 1. This invention, through the installation mechanism, ensures that the wires of the thermal protector element are attached to and connected to the herringbone tube, maintaining inward transmission and contact with the drive seat to form a series circuit. Then, the power supply is connected, illuminating the bulb. The detection mechanism heats the thermal protector element until it breaks the circuit, de-energizing the bulb. The heating temperature is recorded at this point. Individual temperature testing is performed on each thermal protector element, avoiding the inaccurate measurement of the power-off temperature of each individual thermal protector caused by overall heating. This allows for convenient and rapid installation of the thermal protector element, saving workers' disassembly and assembly time and improving testing efficiency.

[0051] 2. This invention, by setting up a detection mechanism, clamps the head of the thermal protector element, causing the heating component to gradually approach the wire end of the thermal protector element, and heats the wire end point-to-point until the thermal protector element is disconnected. The heating temperature at this time is recorded, saving the time of heating the entire thermal protector element in an oven. Heating and recording the temperature of each thermal protector element individually makes the test results more accurate, and reducing the heating range also saves the time of waiting for the oven to cool down.

[0052] 3. This invention, by setting a guide component, ensures that after the wire at the bottom of the thermal protector element contacts the elastic ring, the slider drives the collar to rotate during downward insertion. This causes the elastic ring to rotate in the insertion direction of the thermal protector element wire, maintaining contact between the thermal protector element wire and the inner wall of the herringbone tube, keeping it straight and preventing curling during insertion that would prevent it from connecting in series with the drive seat. This allows the thermal protector element wire to maintain contact with the top of the drive seat, enabling current connection for testing. This allows workers to complete the installation of the thermal protector element with one hand, making the testing process more convenient and faster.

[0053] 4. This invention, by setting up a heating component, heats each thermal protector individually, avoiding the problem of high overall temperature caused by oven heating, which makes it impossible to accurately determine the power-off temperature of the thermal protector. It also heats the wires of the thermal protector element in a small area, saving energy consumption, increasing the rate of heating and cooling, avoiding the problem of long cooling time when heating the whole, and improving detection efficiency.

[0063] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0064] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: a thermal protector testing device, which is described below.

[0065] include:

[0066] Box 1, with an operating cavity 3 inside;

[0067] Slide 6, slide 6 is symmetrically arranged on the inner wall of the operating cavity 3;

[0068] The bottom of the movable plate 4 is slidably connected to the top of the slide rail 6;

[0069] The detection mechanism 7 is symmetrically arranged on the top of the movable plate 4;

[0070] The thermal protector testing equipment also includes:

[0071] Mounting mechanism 5 is evenly arranged on the top of the movable plate 4, and the outer wall of the heating component 704 is in contact with the outer wall of the mounting mechanism 5.

[0072] Sealing plate 2, the outer wall of sealing plate 2 is rotatably connected to the inner wall of box 1.

[0073] During operation, the sealing plate 2 is opened, and the movable plate 4 is pulled out from inside the housing 1. At this time, the detection mechanism 7 is away from the installation mechanism 5. The worker inserts the thermal protector elements 505 one by one into the installation mechanism 5 to make the internal circuit of the installation mechanism 5 connected. Then, the detection mechanism 7 is brought close to the line end of the thermal protector element 505 and the surface of the line of the thermal protector element 505 is heated until the thermal protector element 505 is broken. The temperature at this time is recorded. After the test is completed, the thermal protector element 505 is taken out and the next set is installed.

[0074] Installation mechanism 5 includes:

[0075] Drive base 501, drive base 501 is symmetrically arranged on the top of the movable plate 4;

[0076] Guide assembly 502, the bottom of guide assembly 502 is slidably connected to the top of drive base 501:

[0077] The herringbone tube 503 is located on the top of the drive base 501. The outer wall of the herringbone tube 503 is symmetrically provided with strip grooves 504. The middle of the herringbone tube 503 is connected and the two ends are separated, which makes it easy to separate the circuit of the thermal protector element 505 and to connect it in series in the circuit.

[0078] Installation mechanism 5 also includes:

[0079] Thermal protector element 505 is disposed inside the herringbone tube 503, and the bottom of thermal protector element 505 is in contact with drive seat 501;

[0080] Connecting cable 506 is disposed between the two drive seats 501;

[0081] Light bulb 507 is mounted on the outer wall of connecting wire 506.

[0082] Installation mechanism 5 also includes:

[0083] Wiring power supply 509, the wiring power supply 509 is symmetrically arranged on the top of the movable plate 4;

[0084] The first wire 508 is disposed on the outer wall of the drive seat 501 near the power supply 509, and the other end of the first wire 508 is connected to the power supply 509.

[0085] The second wire 510 is disposed on the outer wall of the drive seat 501 near the power supply 509, and the other end of the second wire 510 is connected to the power supply 509.

[0086] Before installing the thermal protector element 505, the circuit connection path of the equipment is as follows: from the second wire 510 to the connecting wire 506, then to the bulb 507, then in series with the thermal protector element 505, and finally from the second wire 510 to the wiring power supply 509, so that the bulb 507 and the thermal protector element 505 are connected in series, so that the current flows in from the first wire 508 and flows out from the second wire 510.

[0087] During testing, the worker separates the wires of the thermal protector element 505 and inserts them directly into the herringbone tube 503. Driven by the guide assembly 502, the wires of the thermal protector element 505 are brought into contact with the herringbone tube 503 and kept inwards, maintaining contact with the drive seat 501 to form a series circuit. Then, the power supply 509 is connected, illuminating the bulb 507. The testing mechanism 7 then heats the thermal protector element 505 until it breaks the circuit, de-energizing the bulb 507. The heating temperature at this point is recorded. Each thermal protector element 505 is tested individually to avoid overall heating, which would prevent accurate measurement of the de-energizing temperature of each thermal protector. This allows for convenient and quick installation of the thermal protector element 505, saving workers' disassembly and assembly time and improving testing efficiency.

[0088] The testing institutions 7 include:

[0089] The lifting column 701 is installed at the central axis of the top of the movable plate 4;

[0090] The fork plate 702 is installed on the top of the lifting column 701, and the bottom of the fork plate 702 is rotatably connected to the top of the lifting column 701.

[0091] Clamping assembly 703 is evenly distributed on the top of the fork plate 702;

[0092] Heating component 704 is disposed on the inner wall of clamping component 703.

[0093] After the thermal protector element 505 is installed, the lifting column 701 drives the fork plate 702 to rotate, so that the clamping assembly 703 is located directly above the thermal protector element 505. As the clamping assembly 703 gradually approaches the thermal protector element 505, it clamps the head of the thermal protector element 505, so that the heating assembly 704 gradually approaches the wire end of the thermal protector element 505 and heats the wire end point by point until the thermal protector element 505 is disconnected. The heating temperature at this time is recorded, which saves the time of heating the entire thermal protector element 505 in the oven. Heating and recording the temperature of each thermal protector element 505 individually makes the test results more accurate, and reducing the heating range also saves the time of waiting for the oven to cool down.

[0094] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the guide component 502 includes:

[0095] Slider 5021 is symmetrically arranged on the top of drive base 501, and the bottom of slider 5021 is slidably connected to the top of drive base 501.

[0096] Support 5022 is located on top of slider 5021;

[0097] The inner wall of the collar 5023 is fitted with the outer wall of the bracket 5022.

[0098] The guide assembly 502 also includes:

[0099] Extrusion rods 5024 are evenly distributed on the outer wall of collar 5023;

[0100] The elastic ring 5025 is installed at the end of the extrusion rod 5024 away from the collar 5023. The outer wall of the elastic ring 5025 is in contact with the inner wall of the strip groove 504 and the outer wall of the thermal protector element 505. The elastic ring 5025 is made of rubber material with high friction and elasticity.

[0101] During installation, the worker pulls the movable plate 4 outward to separate the bottom wires of the thermal protector element 505 and insert them into the herringbone tube 503. During insertion, the slider 5021 moves the bracket 5022 closer to the herringbone tube 503 and along the groove 504, the elastic ring 5025 enters the herringbone tube 503. After the bottom wires of the thermal protector element 505 contact the elastic ring 5025, during downward insertion, the slider 5021 rotates the collar 5023, causing the elastic ring 5025 to rotate in the direction of wire insertion, maintaining contact between the thermal protector element 505 wires and the inner wall of the herringbone tube 503, keeping them straight and preventing curling during insertion that could prevent series connection with the drive seat 501. This ensures the thermal protector element 505 wires remain in contact with the top of the drive seat 501, allowing for current connection and testing. This allows the worker to complete the installation of the thermal protector element 505 with one hand, making the testing process more convenient and faster.

[0102] Clamping assembly 703 includes:

[0103] Telescopic columns 7031 are evenly arranged on the top of the cross plate 702;

[0104] Connecting rod 7032 is installed on top of telescopic column 7031;

[0105] Drive block 7033 is installed at the bottom of connecting rod 7032;

[0106] Clamping plate 7034 is symmetrically arranged on the inner wall of drive block 7033, and the outer wall of clamping plate 7034 is rotatably connected to the inner wall of drive block 7033.

[0107] Heating component 704 includes:

[0108] Mounting bracket 7041 is evenly arranged at the bottom of the cross plate 702, and the top of the mounting bracket 7041 is rotatably connected to the bottom of the cross plate 702.

[0109] Arc-shaped rods 7042 are symmetrically arranged on the inner wall of the mounting frame 7041, and the top of the arc-shaped rods 7042 is rotatably connected to the inner wall of the mounting frame 7041.

[0110] Heating assembly 704 also includes:

[0111] Heating head 7043 is located at the bottom of the arc-shaped rod 7042;

[0112] Limiting ring 7044 is provided on the outer wall of arc-shaped rod 7042, and the inner wall of limiting ring 7044 is sleeved with the outer wall of arc-shaped rod 7042;

[0113] The elastic rod 7045 is symmetrically arranged on the outer wall of the clamping plate 7034, and the other end of the elastic rod 7045 is connected to the outer wall of the limiting ring 7044.

[0114] After the thermal protector element 505 is installed, the telescopic column 7031 drives the connecting rod 7032 to descend, so that the clamping plate 7034 at the bottom of the connecting rod 7032 clamps the head of the thermal protector element 505. During the descent of the clamping plate 7034, since the arc-shaped ring is sleeved on the arc-shaped rod 7042, the clamping plate 7034 drives the limiting ring 7044 downward, so that the arc-shaped rod 7042 rotates along the mounting bracket 7041, so that the heating heads 7043 at the bottom of the rod come closer to each other and finally contact the wires of the thermal protector element 505 and heat them.

[0115] Each thermal protector is heated individually to avoid the overall temperature being too high due to oven heating, which would make it impossible to accurately determine the power-off temperature of the thermal protector. The wires of thermal protector element 505 are heated in a small area to save energy consumption, increase the rate of heating and cooling, avoid the problem of long cooling time when heating the whole circuit, and improve detection efficiency.

[0116] The specific workflow is as follows:

[0117] Before installing the thermal protector element 505, the circuit connection path of the equipment is as follows: from the second wire 510 to the connecting wire 506, then to the bulb 507, then in series with the thermal protector element 505, and finally from the second wire 510 to the wiring power supply 509, so that the bulb 507 and the thermal protector element 505 are connected in series, so that the current flows in from the first wire 508 and flows out from the second wire 510.

[0118] During installation, the worker pulls the movable plate 4 outward to separate the bottom wires of the thermal protector element 505 and insert them into the herringbone tube 503. During the insertion process, the slider 5021 drives the bracket 5022 to approach the herringbone tube 503 and, along the strip groove 504, allows the elastic ring 5025 to enter the herringbone tube 503. After the bottom wires of the thermal protector element 505 come into contact with the elastic ring 5025, during the downward insertion process, the slider 5021 drives the collar 5023 to rotate, causing the elastic ring 5025 to rotate in the direction of insertion of the thermal protector element 505 wires, maintaining the contact between the thermal protector element 505 wires and the inner wall of the herringbone tube 503, keeping them straight and preventing them from curling during insertion, which would prevent them from being connected in series with the drive seat 501. This ensures that the thermal protector element 505 wires can maintain contact with the top of the drive seat 501, and the current is connected for testing.

[0119] After the thermal protector element 505 is installed, the lifting column 701 drives the fork plate 702 to rotate, so that the clamping assembly 703 is located directly above the thermal protector element 505. As the clamping assembly 703 gradually approaches the thermal protector element 505, it clamps the head of the thermal protector element 505, so that the heating assembly 704 gradually approaches the wire end of the thermal protector element 505 and heats the wire end point by point until the thermal protector element 505 is disconnected. The heating temperature at this time is recorded, saving the time of heating the entire thermal protector element 505 in an oven. The thermal protector elements 505 are heated one by one and the temperature is recorded.

[0120] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
