Description

Technical Field

[0001] The invention relates to the technical field of performance testing, in particular to a performance testing device for a thermal protector. Background Art

[0002] Thermal protectors usually use bimetallic strips or thermistors as temperature-sensitive elements. The bimetallic strip is composed of two metals with different thermal expansion coefficients. When the temperature rises, the bimetallic strip will bend due to the different expansion degrees of the two metals, thereby opening or closing the contacts and cutting off or connecting the circuit.

[0003] During the production of thermal protectors, a test device is required to test the thermal protector's electrical variables to ensure reliable triggering under overcurrent or overheating conditions. Existing test devices, when used, clamp the current clamp to the thermal protector circuit for energized testing. Due to the high oxygen content, the contact points oxidize rapidly, forming an oxide layer that affects the accuracy of the thermal protector test and reduces the test precision. To address this issue, we propose a performance test device for thermal protectors.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing testing devices on the market. Even if they can be solved, they need to be solved with the help of external tools, which makes it impossible to achieve the desired effect.

The inner cavity of the second protective shell 3201 is rotatably connected to the second blowing air cylinder 3203 through a bearing, wherein the surfaces of the two second blowing air cylinders 3203 are fixedly sleeved with a second synchronous wheel 3206, wherein the surfaces of the two second blowing air cylinders 3203 are both provided with a second synchronous belt 3205, and the second synchronous belt 3205 transmission sleeve is arranged on the surface of the second synchronous wheel 3206 and the first synchronous wheel 3114.

[0044] As a further limitation of the present invention, the surface of the processing shell 3102 is fixedly connected to an air supply pipe 3104, and there are four air supply pipes 3104. One end of the air supply pipe 3104 passes through the mounting bracket 3103 and is fixedly connected to the top of the first protective shell 3107. The top of the test device body 1 is fixedly connected to a guide block 3105, and there are several guide blocks 3105. By setting the guide blocks 3105, the blown air can be guided to ensure the effect of the wind curtain formation, so that it can better reduce the oxygen content around the placement seat 2, thereby ensuring the test effect.

The top of the second protective shell 3201 is fixedly connected to the air outlet end of the air supply pipe 3104. By setting the fourth bevel gear 3202, when the second air blowing tube 3203 on one side rotates, the other two second air blowing tubes 3203 can be driven to rotate, so that they can blow out an air curtain, thereby forming an outer air curtain, further reducing the oxygen content around the placement seat 2, thereby reducing the oxidation reaction at the contact point, and ensuring the effect of the thermal protector electrical variable test.

[0046] By setting up the suction and blowing unit 31 and the auxiliary unit 32 for use in conjunction, the purpose of improving the test accuracy can be achieved. When testing the thermal protector, the oxygen content during the test can be reduced, thereby effectively reducing the oxidation reaction, ensuring the accuracy of the thermal protector test data, and improving the effect of the thermal protector test, thereby ensuring the accuracy and reliability of the thermal protector electrical variable test.

[0047] The specific implementation of this embodiment is as follows: when testing, the servo motor 3111 drives the suction fan blade 3112 to rotate, thereby sucking the air within the range of the placement seat 2, allowing the air to enter the processing shell 3102 through the short tube 3110, and separated by the oxygen diaphragm 3101, so that the oxygen can be discharged from the processing shell 3102, thereby reducing the oxygen content of the air entering the processing shell 3102, and the air with low oxygen content is transported to the first protective shell 3107 and the second protective shell 3201 through the air supply pipe 3104. When the servo motor 3111 is running, the air is sucked out through the first protective shell 3107 and the second protective shell 3201. The second bevel gear 3116 drives the third bevel gear 3117 to rotate, allowing the rotating rod 3113 to rotate, allowing the first synchronous wheel 3114 on it to rotate, thereby driving the first synchronous belt 3115 to rotate. Through the first synchronous belt 3115, the other two first synchronous wheels 3114 rotate, so that the first blowing air cylinders 3108 on both sides can rotate, thereby blowing air downward to form an air curtain. When the first blowing air cylinders 3108 on both sides rotate, the first bevel gear 3109 allows the other two first blowing air cylinders 3108 to rotate again, blowing out two air curtains again. , so that four wind curtains can be formed around the placement seat 2, thereby preventing external air from entering the placement seat 2, thereby reducing the oxygen content in the test space, and at the same time, the air with low oxygen content transported by the air pipe 3104 can be blown out through the first blowing air cylinder 3108, further reducing the oxygen content. When the first blowing air cylinder 3108 rotates, the first synchronous wheel 3114 thereon can drive the second synchronous belt 3205 to rotate, and then the second synchronous wheel 3206 rotates through the second synchronous belt 3205, so that the second blowing air cylinders 3203 on both sides rotate, blowing out the two outer At the same time, the other two second air blowing cylinders 3203 blow out air curtains through the fourth bevel gear 3202 to form four outer air curtains, thereby further preventing the external air from entering the test space. At the same time, the air with low oxygen content transported by the air pipe 3104 is blown out along with the second air blowing cylinder 3203 to form an air curtain with low oxygen content, thereby ensuring that the oxygen content in the test space is low, so that the degree of oxidation at the contact point between the thermal protector and the current clamp 405 is reduced during the power-on test, thereby effectively ensuring the accuracy of the test data and improving the effect of the thermal protector test.

[0048] Example 2: Please refer to Figures 1-13 The present invention provides a technical solution: a performance testing device for a thermal protector. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0049] As a further limitation of the present invention, a slow clamping mechanism 4 is provided on the surface of the placement seat 2;

[0050] The slow clamping mechanism 4 includes a current clamp 405, which is fixedly connected to the surface of the placement seat 2. There are two current clamps 405. The top of the current clamp 405 is fixedly connected to an inclined plate 403. The surface of the current clamp 405 is rotatably connected to a cylindrical rod 409 through a bearing. Both ends of the cylindrical rod 409 pass through one side of the current clamp 405 and are movably sleeved with a torsion spring 411. The two ends of the torsion spring 411 are respectively fixedly connected to the current clamp 405 and the surface of the cylindrical rod 409. The surface of the cylindrical rod 409 is fixedly sleeved with a conductive clamping plate 406. A reset spring 412 is fixedly connected between the upper and lower clamping plates of the current clamp 405. By setting the torsion spring 411, when the conductive clamping plate 406 clamps the thermal protector circuit, it can be slowly and fully contacted for clamping, thereby preventing direct and full contact from causing surge current and ensuring the test effect of the thermal protector.

[0051] The inner cavity of the placement seat 2 is fixedly connected to two support rods 408, and a T-shaped block 407 is movably sleeved on the surface of the support rod 408. A sliding rod 404 is fixedly connected to one side of the T-shaped block 407, and one end of the sliding rod 404 passes through one side of the inclined plate 403. A downward pressing hole 413 is provided on the surface of the inclined plate 403 for cooperating with the sliding rod 404, and a guide hole 414 is provided on the top of the placement seat 2 for cooperating with the T-shaped block 407. By setting the guide hole 414, the T-shaped block 407 can be guided so that the T-shaped block 407 can move stably, so that it can stably press down the inclined plate 403, thereby ensuring the slow clamping effect of the conductive splint 406 on the thermal protector circuit, thereby effectively ensuring the stability of the current passing through, so that it can be tested more accurately.

[0052] The inner cavity of the placement seat 2 is rotatably connected to two rotating rods 415 through bearings. The surface fixed sleeve of the rotating rod 415 is provided with a fourth synchronous wheel 410, and the surface fixed sleeve of one of the rotating rods 3113 is provided with a third synchronous wheel 401. Two third synchronous belts 402 are provided on one side of the placement seat 2. The third synchronous belt 402 transmission sleeve is arranged on the surface of the third synchronous wheel 401 and the fourth synchronous wheel 410. The surface of the rotating rod 415 is respectively provided with a spiral groove 416 and an annular groove 418. The spiral groove 416 is connected to the annular groove 418. The inner cavity of the spiral groove 416 is slidably connected to a sliding block 417. One end of the sliding block 417 is fixedly connected to the surface of the T-shaped block 407.

[0053] The inner cavity of the placement seat 2 is fixedly connected to a telescopic rod 420, one end of the telescopic rod 420 is fixedly connected to a push plate 419, and a push spring 421 is movably sleeved on the surface of the telescopic rod 420, and the two ends of the push spring 421 are respectively fixedly connected to the inner cavity of the placement seat 2 and one side of the push plate 419.

[0054] By setting up a slow clamping mechanism 4, the purpose of protection testing can be achieved. When testing the thermal protector, it can effectively prevent surge current from being generated when the equipment is turned on and off, ensuring the stability of the current during testing, thereby improving the accuracy of the measurement data of the thermal protector and the accuracy of the test data.

[0055] The specific implementation of this embodiment is as follows: when in use, the current clamp 405 is connected to the test device body 1 through a wire, the thermal protector to be tested is placed in the card slot of the placement seat 2, and then the two lines of the thermal protector are passed through the card slot so that they can extend to the current clamp 405. When the servo motor 3111 is running, the servo motor 3111 first rotates slowly until the sliding block 417 moves to the inner cavity of the annular groove 418. The servo motor 3111 starts to run quickly, and the rotating rod 3113 rotates, thereby rotating the third synchronous wheel 401. The fourth synchronous wheel 410 can be driven to rotate through the third synchronous belt 402, so that the rotating rod 415 can rotate, and the sliding block 417 moves in the spiral groove 416 , so that the sliding block 417 can drive the T-shaped block 407 to move on the support rod 408, and at the same time, under the guidance of the guide hole 414, the T-shaped block 407 can move stably, push the slide bar 404 to move in the lower pressure hole 413, and let it exert downward pressure on the inclined plate 403, so that the current clamp 405 can rotate, so that one end of the conductive clamp 406 first contacts the surface of the thermal protector circuit to energize, and does not allow it to directly and fully contact to avoid instantaneous conduction, thereby effectively preventing the generation of surge current and ensuring the stability of the current. After one point of contact, the sliding block 417 continues to move, so that the T-shaped block 407 can continue to drive the slide bar 404 to move, thereby moving to the other side of the lower pressure hole 413, allowing the conductive clamp 406 to slowly When the conductive clamping plate 406 is slowly pressed down and rotated, the cylindrical rod 409 follows the rotation to twist the torsion spring 411. After the slide bar 404 moves to the other side of the pressing hole 413, the sliding block 417 moves from the spiral groove 416 into the annular groove 418. At the same time, the push plate 419 is squeezed to allow the push spring 421 and the telescopic rod 420 to shrink, so that the sliding block 417 is slidably connected to the inner wall of the annular groove 418, so that the sliding block 417 is in the annular groove 418 and will not continue to move, allowing the rotating rod 415 to continue to rotate. It will not affect the operation of the servo motor 3111. After the sliding block 417 enters the annular groove 418, the servo motor 3111 accelerates to ensure that the suction fan blades 3112, the first blowing air cylinder 3108 and the second blowing air cylinder 3203 can effectively inhale and blow air, so that a low oxygen area is formed in the test space. At the same time, the sliding rod 404 can stop moving and continue to apply pressure to the inclined plate 403, so that the conductive clamping plate 406 can stably clamp the circuit of the thermal protector for power-on testing. After the test is completed, the output end of the servo motor 3111 is reversed, and the telescopic rod 420 is reset by pushing the spring 421 to reset, so that the push plate 419 pushes the sliding block 417 out of the annular groove 418 and into the spiral groove 416.Sliding block 417 can drive T-shaped block 407 to move back, which in turn drives slide bar 404 to move back, reducing the pressure on inclined plate 403. Under the action of torsion spring 411 and return spring 412, conductive clamp 406 and current clamp 405 can rotate, moving conductive clamp 406 away from the thermal protector circuit, allowing the thermal protector to be removed, thus completing the test.
