Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and in particular to an electronic wire thermal extension test device. Background Technology

[0002] Electronic wires are insulated wires used to connect electronic devices and transmit electrical energy or signals. They are widely used in home appliances, automobiles, communications, industrial control and other fields. They are the basic components for realizing circuit conduction in electronic systems. Their core function is to stably transmit electrical energy or signals in complex environments.

[0003] The existing thermal stretching test equipment requires opening the chamber door to remove the inner cable and test the length of the heated weight. The weight must then be manually removed and the cable heated again to test its recovery rate. All of these steps are done manually. During the process, some parts inside the test chamber are affected by high temperature, which can easily burn the operator's hands, posing a certain safety hazard.

[0004] An existing patent (publication number: CN219573972U) discloses a thermal extension test device for cables. It generates heat by connecting an external heating device through an inner serpentine tube to heat the cable sheath for testing. After testing, a motor is started to drive a lead screw to adjust the position of the measuring scale left and right. An electric telescopic rod is pushed upward to measure the cable through the measuring scale. Finally, an electric slide rail moves an electric cutter to cut the cable. This eliminates the need for manual arm placement inside the chamber, avoiding burns to workers' arms and potential safety hazards. Furthermore, the heat inside is not dissipated, preventing reheating and improving testing efficiency.

[0005] To address the aforementioned issues, existing patents offer solutions, but these solutions are inconvenient for installing electronic wires. In practical use, the lack of a movable structure makes it difficult to adjust the position of the clamping structure, hindering the installation of wire harnesses. Furthermore, when multiple electronic wires need to be tested simultaneously, the fixed clamping structure cannot flexibly allocate the space within the box, requiring sequential testing of individual wires. This makes it difficult to meet the high-efficiency quality inspection requirements of electronic wire production lines, reducing the practicality of the device.

[0006] To address this, an electronic wire thermal stretching test device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide an electronic wire thermal stretching test device that solves the problems of existing thermal stretching test devices being inconvenient for installing electronic wires. In actual use, due to the lack of a movable structure, it is difficult to adjust the position of the clamping structure, making it inconvenient to install wire harnesses. At the same time, when multiple electronic wires need to be tested simultaneously, the fixed clamping structure cannot flexibly allocate the space inside the box, and can only test one wire at a time, which makes it difficult to meet the high-efficiency quality inspection requirements of electronic wire production lines and reduces the practicality of the device.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an electronic wire thermal extension testing device, comprising a housing, a movable component fixedly connected inside the housing, and several extension components movably connected inside the movable component.

A handle is fixedly connected to the right side of the bidirectional screw, and clamping plates are threaded to both sides of the surface of the bidirectional screw. A weight placement tray is fixedly connected to the bottom of the bottom fixing block.

[0010] Preferably, both sides of the front side of the fixing plate are provided with fixing grooves, and a scale is fixedly connected inside the fixing grooves.

[0011] Preferably, the clamping plate has a threaded hole inside for use with a bidirectional screw, and the surface of the bidirectional screw is in contact with the inner wall of the threaded hole.

At the same time, with the help of the magnetic force of the magnetic block, the movable block is attracted and fixed, ensuring the stability of the extension component during the test and avoiding the impact of positional deviation on the test results, thus improving the practicality of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] An electronic wire thermal extension test device includes a housing 1. A movable component 2 is fixedly connected inside the housing 1, and several extension components 3 are movably connected inside the movable component 2. The movable component 2 includes two positioning rods 201, and movable blocks 202 are slidably connected to the surfaces of the two positioning rods 201. The positioning rods 201 are located at the top and bottom of the inner wall of the housing 1. A fixed frame 203 is fixedly connected between the opposite sides of the two movable blocks 202. Several L-shaped plates 204 are fixedly connected to the top and bottom of the inner wall of the fixed frame 203, and a buckle block 205 is rotatably connected to the front side of the L-shaped plate 204.

[0028] In this embodiment: the positioning rod 201 and the moving block 202 work together to form a guide structure, allowing the fixed frame 203 to move smoothly along the positioning rod 201 under the constraint of the moving block 202. The position of the fixed frame 203 can be adjusted as needed to expose the extension component 3, facilitating the detection of the electronic wire. Simultaneously, the L-shaped plate 204 and the latching block 205 work together to form a latching structure, allowing the extension component 3 to move smoothly under the constraint of the L-shaped plate 204. Once in position, rotating the latching block 205 locks the component in place. The number of extension components 3 installed can be adjusted according to the actual situation to support simultaneous detection of multiple wire harnesses, which improves the ease of use of the moving component 2. Then, by rotating the handle 307, the bidirectional screw 305 is driven to rotate, which drives the clamping plate 306 to move towards each other along the bidirectional screw 305, so that the clamping plate 306 contacts the electronic wire and realizes the clamping and fixing of the electronic wire of specific specifications. At the same time, with the help of the load structure formed by the weight placement plate 308, weights can be placed on the weight placement plate 308 to increase the weight and complete the stretching of the electronic wire, which improves the ease of use of the extension component 3.

[0029] Specifically, such as Figure 5As shown, the extension component 3 includes a fixed plate 301. T-shaped sliders 302 are movably connected to the top and bottom of the fixed plate 301. The fixed plate 301 is slidably connected to the surface of the L-shaped plate 204. A spring 304 is fixedly connected between the opposite sides of the two T-shaped sliders 302. The top T-shaped slider 302 is fixedly connected to the fixed plate 301. Fixed blocks 303 are fixedly connected to the front sides of the two T-shaped sliders 302. Bidirectional screws 305 are rotatably connected inside the two fixed blocks 303. A handle 307 is fixedly connected to the right side of the bidirectional screws 305. Clamping plates 306 are threadedly connected to both sides of the surface of the bidirectional screws 305. A weight placement tray 308 is fixedly connected to the bottom of the bottom fixed block 303.

[0030] Specifically, such as Figure 5 As shown, fixing grooves 4 are provided on both sides of the front side of fixing plate 301, and a scale 5 is fixedly connected inside the fixing groove 4.

[0031] Specifically, such as Figure 5 As shown, the clamping plate 306 has a threaded hole 6 inside for use with the bidirectional screw 305, and the surface of the bidirectional screw 305 is in contact with the inner wall of the threaded hole 6.

[0032] In this embodiment: the bidirectional screw 305 and the threaded hole 6 work together to drive the clamping plate 306 to move towards each other along the bidirectional screw 305, so that the clamping plate 306 contacts the electronic wire to complete the clamping and fixing, thereby fixing the electronic wire of a specific specification. At the same time, the scale 5 and the fixing groove 4 work together to make the scale 5 and the fixing plate 301 tightly connected, which can directly and accurately measure the thermal elongation of the electronic wire without additional calibration, thus improving the convenience of using the extension component 3.

[0033] Specifically, such as Figure 3 As shown, the top and bottom of the inner wall of the box 1 are provided with moving grooves 7 for use with moving block 202, and the positioning rod 201 is located inside the moving groove 7. A magnetic block 8 is fixedly connected to the left side of the inner wall of the moving groove 7, and the magnetic block 8 is in contact with the moving block 202.

[0034] Specifically, such as Figure 5 As shown, the top and bottom of the fixed plate 301 are provided with positioning holes 9 for use with the L-shaped plate 204, and the surface of the L-shaped plate 204 is in contact with the inner wall of the positioning hole 9.

[0035] In this embodiment: the L-shaped plate 204 and the positioning hole 9 work together to allow the fixing plate 301 to move smoothly under the constraint of the L-shaped plate 204. After moving into place, the buckle block 205 is rotated to lock it, realizing the quick installation and removal of the extension component 3. The number of extension components 3 can be adjusted according to the actual situation, supporting the simultaneous detection of multiple wire harnesses. At the same time, the moving block 202 and the moving groove 7 work together to allow the moving block 202 to move along the moving groove 7 under the constraint of the positioning rod 201. This can simultaneously constrain the movement of the fixing frame 203, facilitating the quick assembly of the extension component 3. The magnetic force of the magnetic block 8 is used to attract and fix the moving block 202, ensuring the stability of the extension component 3 during the test, avoiding positional deviation from affecting the test results, and improving the ease of use of the moving component 2.

[0036] Specifically, such as Figure 2 , Figure 3 As shown, an observation glass 10 is embedded inside the front side of the box 1, and drying lamps 11 are fixedly connected to the four corners inside the box 1.

[0037] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a temperature detector 12 is fixedly connected to the front side of the top of the chamber 1, and the detection probe of the temperature detector 12 extends into the interior of the chamber 1. A controller 13 is fixedly connected to the right side of the front of the chamber 1, and the controller 13 is electrically connected to the drying lamp 11 and the temperature detector 12.

[0038] In this embodiment: the temperature detector 12 can collect the temperature changes inside the chamber 1 in real time and transmit the data to the controller 13. The controller 13 adjusts the power of the drying lamp 11 accordingly, which can accurately adjust the temperature inside the chamber 1 and avoid temperature fluctuations affecting the accuracy of the test. At the same time, the detection process of the electronic wires inside the chamber 1 can be observed with the help of the observation glass 10. The two work together to ensure the stability of the test environment and facilitate real-time monitoring of the sample status, thus improving the practicality of the device.

[0039] Working principle: When performing a thermal stretching test on electronic wires, the guide structure formed by the moving block 202 and the positioning rod 201 is first used to make the fixed frame 203 move smoothly along the positioning rod 201 under the constraint of the moving block 202, so as to flexibly adjust the position of the extension component 3 to meet the needs of the operator. First, the fixed frame 203 is pulled out to expose the extension component 3. Then, according to the number of electronic wires to be tested, the corresponding extension component 3 is taken out. The positioning hole 9 of the fixed plate 301 is aligned with the L-shaped plate 204 and pushed, so that the fixed plate 301 moves along the L-shaped plate 204. Plate 204 slides to the appropriate position and the locking block 205 is rotated to lock it in place, thus fixing multiple extension components 3 to support simultaneous testing of multiple wire harnesses. Entering the sample fixing stage, the handle 307 is rotated to drive the bidirectional screw 305 to rotate, causing the clamping plate 306 to move towards each other along the bidirectional screw 305, making the clamping plate 306 contact the electron wire and achieving clamping and fixing of the specific specification electron wire. Next, weights are placed on the weight placement tray 308 to add additional weight, applying a constant longitudinal load to the electron wire. After completing the preliminary preparations, the fixing frame 203 is reset, allowing the moving block 2... 02. The magnetic block 8 comes into contact with the wire to complete the adsorption and fixation, preventing positional displacement during the test. The drying lamp 11 is activated to raise the temperature inside the chamber 1, entering the thermal extension test stage. During the test, the temperature detector 12 can collect the temperature changes inside the chamber 1 in real time and transmit the data to the controller 13. The controller 13 adjusts the power of the drying lamp 11 accordingly to achieve precise control of the high-temperature environment inside the chamber 1. The electronic wire begins thermal extension under the combined action of high temperature and load. At the same time, the spring 304 in the fixing plate 301 can cooperate with the T-shaped slider 30 2. Buffering tension to prevent the electronic wire from breaking due to excessive instantaneous force. The operator can observe the changes of the electronic wire in the chamber 1 in real time through the observation glass 10. At the same time, the scale 5 can be used to directly and accurately measure the thermal elongation of the electronic wire without additional calibration. When the test reaches the set time, the drying lamp 11 is turned off by the controller 13. After the temperature inside the chamber 1 drops to room temperature, the fixing frame 203 is pulled out, the weight is removed, and the handle 307 is turned in the opposite direction to loosen the clamp 306. The tested electronic wire is then taken out, thus completing the entire electronic wire thermal elongation test process.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
