Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of thermal protector detection, in particular to a thermal protector detection device. Background Art
[0002] Thermal protectors are electrical components used to protect circuitry from burnout due to prolonged overcurrent. The core component of a thermal protector is a bimetallic strip, which heats up when current flows through it. Due to the different thermal expansion coefficients of the two alloys, the alloys tend to bend in one direction, moving away from the conductive contacts, thereby breaking the circuit and protecting the electrical equipment. Existing thermal protectors operate on the principle that the current flowing into the thermal element generates heat, causing the bimetallic strips, which have different expansion coefficients, to deform. When the deformation reaches a certain distance, it pushes a connecting rod, disconnecting the control circuit, thereby de-energizing the contactor and disconnecting the main circuit, thus protecting the motor from overload.
[0003] The existing method for testing the operating temperature of a thermal protector involves connecting the two wires of the thermal protector to a circuit, placing the thermal protector in an oven, and then increasing the oven temperature at a specified rate. The disconnection temperature of the thermal protector is then detected by detecting the on / off state of the circuit. When the thermal protector disconnects the circuit, the real-time temperature inside the oven is the thermal protector's operating temperature. This method has low temperature detection efficiency. Each test requires connecting the two wires of the thermal protector to a dedicated fixture, which is cumbersome to install. Each test also requires increasing the oven temperature from low to high and then lowering it after each test, which is time-consuming. Summary of the Invention

[0050] 1. The present invention provides an installation mechanism so that the wires of the thermal protector element are attached to the herringbone tube and kept inwardly transferred, and the wires are kept in contact with the drive seat to form a series circuit. Subsequently, the wiring power is turned on to light the bulb. The thermal protector element is heated in conjunction with the detection mechanism until it short-circuits, thereby powering off the bulb. The heating temperature at this time is recorded, and a separate temperature test is performed on each thermal protector element, avoiding the use of overall heating, which results in the inability to accurately measure the power-off temperature of each thermal protector.

[0052] 3. The present invention provides a guide assembly. After the electric wire at the bottom of the thermal protector element contacts the elastic ring, the slider drives the ring to rotate during the downward insertion process, causing the elastic ring to rotate along the insertion direction of the electric wire of the thermal protector element, thereby maintaining the contact between the electric wire of the thermal protector element and the inner wall of the herringbone tube, keeping it in a straight state, and avoiding curling during the insertion process, which may lead to the inability to connect it in series with the drive seat.

This allows workers to complete the installation of the thermal protector element with one hand, making the testing process more convenient and quick.
[0053] 4. The present invention heats each thermal protector individually by setting a heating component, avoiding the problem of high overall temperature caused by oven heating and inability to accurately determine the power-off temperature of the thermal protector. The wires of the thermal protector elements are heated in a small range, saving energy consumption, increasing the rate of heating and cooling, avoiding the problem of long cooling time when the overall temperature is increased, and improving detection efficiency.

[0063] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.
[0064] Example 1, please refer to Figure 1-Figure 5 , the present invention provides a technical solution: a thermal protector detection device is described as follows.
[0065] include:
[0066] The box body 1 has an operating chamber 3 formed inside.
[0067] The slide 6 is symmetrically arranged on the inner wall of the operating chamber 3;
[0068] The movable plate 4 has a bottom portion slidably connected to the top portion of the slideway 6;
[0069] The detection mechanism 7 is symmetrically arranged on the top of the movable plate 4;
[0070] The thermal protector detection equipment also includes:
[0071] The mounting mechanism 5 is evenly arranged on the top of the movable plate 4, and the outer wall of the heating component 704 contacts the outer wall of the mounting mechanism 5;
[0072] The sealing plate 2 has an outer wall that is rotatably connected to the inner wall of the box body 1 .
[0073] During operation, the sealing plate 2 is opened and the movable plate 4 is pulled out from the inside of the box 1. At this time, the detection mechanism 7 is away from the installation mechanism 5. The worker inserts the thermal protector elements 505 into the installation mechanism 5 one by one to connect the internal circuit of the installation mechanism 5. Then, the detection mechanism 7 is placed close to the line end of the thermal protector element 505 to heat the line surface of the thermal protector element 505 until the thermal protector element 505 is disconnected. The temperature at this time is recorded. After the detection is completed, the thermal protector element 505 is taken out and the next group is installed.
[0074] The mounting mechanism 5 comprises:
[0075] The driving seat 501 is symmetrically arranged on the top of the moving plate 4;
[0076] The guide assembly 502 has a bottom portion slidably connected to the top portion of the drive seat 501.
[0077] The herringbone tube 503 is arranged on the top of the driving seat 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 is convenient for separating the circuit of the thermal protector element 505 and facilitating series connection in the circuit.
[0078] The mounting mechanism 5 further comprises:
[0079] Thermal protector element 505, the thermal protector element 505 is arranged inside the herringbone tube 503, and the bottom of the thermal protector element 505 is in contact with the driving seat 501;
[0080] A connecting line 506 is provided between the two driving seats 501;
[0081] The light bulb 507 is arranged on the outer wall of the connecting line 506 .
[0082] The mounting mechanism 5 further comprises:
[0083] The wiring power supply 509 is symmetrically arranged on the top of the moving plate 4;
[0084] A first wire 508 is provided on the outer wall of the driving base 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 arranged on the outer wall of the driving base 501 close to the wiring power supply 509 , and the other end of the second wire 510 is connected to the wiring power supply 509 .
[0086] Before installing the thermal protector element 505, the device circuit connection path is: the second wire 510 is connected to the connecting wire 506, then to the light bulb 507, and then the thermal protector element 505 is connected in series. Finally, the second wire 510 is connected to the wiring power supply 509, so that the light bulb 507 and the thermal protector element 505 are connected in series, so that the current flows into the first wire 508 and flows out of the second wire 510.
[0087] During testing, the worker separates the wires of the thermal protector element 505, inserts them directly from the herringbone tube 503, and, driven by the guide component 502, makes the wires of the thermal protector element 505 fit into the herringbone tube 503 and keep passing inward, keeping its wires in contact with the drive seat 501 to form a series circuit. Then, the wiring power supply 509 is turned on to light up the light bulb 507, and the thermal protector element 505 is heated in conjunction with the detection mechanism 7 until it breaks down, causing the light bulb 507 to lose power. The heating temperature at this time is recorded, and a separate temperature test is performed on each thermal protector element 505 to avoid overall heating, which makes it impossible to accurately measure the power-off temperature of each thermal protector. The thermal protector element 505 can be installed conveniently and quickly, saving workers' disassembly and assembly time and improving detection efficiency.
[0088] The detection mechanism 7 includes:
[0089] Lifting column 701, which is installed at the center axis of the top of the moving plate 4;
[0090] The cross plate 702 is mounted on the top of the lifting column 701, and the bottom of the cross plate 702 is rotatably connected to the top of the lifting column 701;
[0091] The clamping assembly 703 is evenly arranged on the top of the cross plate 702;
[0092] The heating component 704 is arranged on the inner wall of the clamping component 703 .
[0093] After the thermal protector element 505 is installed, the lifting column 701 drives the cross 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, the head of the thermal protector element 505 is clamped, 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 using an oven to heat the thermal protector element 505 as a whole. The thermal protector elements 505 are heated and the temperature is recorded one by one, so that the test results are more accurate, the heating range is narrowed, and the time of waiting for the oven to cool down is saved.
[0094] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: Based on Example 1, the guide component 502 includes:
[0095] Slider 5021, the slider 5021 is symmetrically arranged on the top of the driving seat 501, and the bottom of the slider 5021 is slidably connected to the top of the driving seat 501;
[0096] The bracket 5022 is provided on the top of the slider 5021;
[0097] The inner wall of the collar 5023 is sleeved with the outer wall of the bracket 5022 .
[0098] The guide assembly 502 further includes:
[0099] Extrusion rods 5024, which are evenly arranged on the outer wall of the collar 5023;
[0100] The elastic ring 5025 is installed at the end of the extrusion rod 5024 away from the ring 5023. The outer wall of the elastic ring 5025 contacts the inner wall of the strip groove 504. The outer wall of the elastic ring 5025 contacts 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, separates the wires at the bottom of the thermal protector element 505 and inserts them into the herringbone tube 503. During the process of inserting the herringbone tube 503, the slider 5021 drives the bracket 5022 close to the herringbone tube 503 and allows the elastic ring 5025 to enter the herringbone tube 503 along the strip groove 504. After the wires at the bottom of the thermal protector element 505 contact the elastic ring 5025, during the downward insertion process, the slider 5021 drives the sleeve 5023 to rotate, causing the elastic ring 5025 to rotate along the insertion direction of the wires of the thermal protector element 505, keeping the wires of the thermal protector element 505 in contact with the inner wall of the herringbone tube 503, keeping them straight to avoid curling during the insertion process, which may cause the drive seat 501 to be unable to be connected in series. The wires of the thermal protector element 505 can maintain contact with the top of the drive seat 501, and the current is connected for 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 quick.
[0102] The clamping assembly 703 includes:
[0103] Telescopic columns 7031 are evenly arranged on the top of the cross plate 702;
[0104] Connecting rod 7032, which is installed on the top of telescopic column 7031;
[0105] A driving block 7033 is mounted on the bottom of the connecting rod 7032;
[0106] The clamping plate 7034 is symmetrically arranged on the inner wall of the driving block 7033 , and the outer wall of the clamping plate 7034 is rotatably connected to the inner wall of the driving block 7033 .
[0107] The heating assembly 704 includes:
[0108] The mounting brackets 7041 are evenly arranged on the bottom of the cross plate 702, and the top of the mounting brackets 7041 is rotatably connected to the bottom of the cross plate 702;
[0109] The arc-shaped rod 7042 is symmetrically arranged on the inner wall of the mounting frame 7041 , and the top of the arc-shaped rod 7042 is rotatably connected to the inner wall of the mounting frame 7041 .
[0110] The heating assembly 704 further includes:
[0111] The heating head 7043 is provided at the bottom of the arc-shaped rod 7042;
[0112] A limiting ring 7044 is provided on the outer wall of the arc-shaped rod 7042 , and the inner wall of the limiting ring 7044 is sleeved with the outer wall of the 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 downward, 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 process of the clamping plate 7034 descending, the arc ring is sleeved on the arc rod 7042, so that the clamping plate 7034 drives the limiting ring 7044 downward, causing the arc rod 7042 to rotate along the mounting frame 7041, so that the heating head 7043 at the bottom approaches each other, and finally contacts the wire of the thermal protector element 505, thereby heating it.
[0115] Each thermal protector is heated individually to avoid the overall temperature being too high due to oven heating, which makes it impossible to accurately determine the power-off temperature of the thermal protector. The wires of the thermal protector element 505 are heated in a small area to save energy, increase the rate of heating and cooling, avoid the problem of long cooling time when the overall temperature is increased, and improve detection efficiency.
[0116] The specific workflow is as follows:
[0117] Before installing the thermal protector element 505, the device circuit connection path is: the second wire 510 is connected to the connecting wire 506, then to the light bulb 507, and then the thermal protector element 505 is connected in series. Finally, the second wire 510 is connected to the wiring power supply 509, so that the light bulb 507 and the thermal protector element 505 are connected in series, so that the current flows into the first wire 508 and flows out of the second wire 510.
[0118] During installation, the worker pulls the movable plate 4 outward, separates the wires at the bottom of the thermal protector element 505 and inserts them into the herringbone tube 503. During the process of inserting the herringbone tube 503, the slider 5021 drives the bracket 5022 close to the herringbone tube 503 and makes the elastic ring 5025 enter the herringbone tube 503 along the strip groove 504. After the wires at the bottom 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 along the insertion direction of the wires of the thermal protector element 505, keeping the wires of the thermal protector element 505 in contact with the inner wall of the herringbone tube 503, keeping them in a straight state to avoid curling during the insertion process, which may cause the wires to be unable to be connected in series with the drive seat 501, so that the wires of the thermal protector element 505 can maintain contact with the top of the drive seat 501, and the current is connected and then tested;
[0119] After the thermal protector element 505 is installed, the lifting column 701 drives the cross 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, the head of the thermal protector element 505 is clamped, 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 using an oven to heat the thermal protector element 505 as a whole, and the thermal protector elements 505 are heated one by one and the temperature is recorded.
