Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrothermal technology, and in particular to a functional testing device for testing PTC ceramic heaters. Background Technology
[0002] A PTC ceramic heater is an electric heater that uses PTC ceramic elements and generates heat through resistance heating. A PTC ceramic heater functional testing device is used to test the performance of PTC ceramic heaters, comprehensively evaluating key indicators such as heating efficiency, temperature control, and safety. Before performing functional testing on a PTC heater, operators need to manually connect the female connector on the PTC heater to the male connector on the testing device. This manual operation not only consumes a lot of time and energy for operators but also becomes a bottleneck in the entire testing process during large-scale testing, reducing overall testing efficiency. Furthermore, frequent manual connection may cause wear or damage to the male connector, thus affecting the heater's performance and service life. Utility Model Content
[0003] In order to overcome the shortcomings of the low detection efficiency of the existing technology, the purpose of this utility model is to provide a functional testing device for PTC ceramic heaters with high detection efficiency.
[0004] The technical solution of this utility model is as follows: a functional testing device for testing PTC ceramic heaters, including a mounting base, switches symmetrically arranged on the top of the front side of the mounting base, a mounting block fixedly connected to the mounting base, a sliding groove opened in the middle of the front side of the mounting block, sliding grooves symmetrically arranged on the left and right sides of the mounting block, a PTC heater placed on the rear side of the mounting block, a female connector provided on the front side of the PTC heater, the female connector placed in the sliding groove in the middle of the mounting block, a male connector provided on the mounting base, the male connector fixedly connected to the front side of the mounting base, two cylinders fixedly connected to the mounting block, a push plate fixedly connected to the telescopic rod of the cylinder, the push plate slidingly connected in the sliding grooves symmetrically arranged on the mounting block, the female connector placed on the front side of the push plate, sensors provided on the two push plates, and the push plates used to push the female connector and the male connector to mate.
[0005] Furthermore, it is particularly preferred that the mounting block also includes a support frame, with symmetrical support frames provided on the mounting block and the support frames fixedly connected to the mounting block. A rotating shaft is fixedly connected to the support frame on the left side, and a limiting plate is rotatably connected to the rotating shaft. Elastic elements are symmetrically sleeved on the rotating shaft, with one end of the elastic element fixedly connected to the support frame and the other end of the elastic element fixedly connected to the limiting plate. A magnet is provided on the support frame on the right side, and the limiting plate is used to prevent displacement during the docking process.
[0006] Furthermore, it is particularly preferred that the mounting base also includes support feet, with multiple support feet fixedly connected to the bottom of the mounting base for supporting the overall device.
[0007] In addition, it is particularly preferred that the mounting block also includes an anti-slip pad, which is fixedly connected to the symmetrical groove of the mounting block. The anti-slip pad is used to increase friction and prevent the push plate from shifting during movement.
[0008] Furthermore, it is particularly preferred that the mounting block also includes a limiting block, wherein the mounting block is symmetrically provided with limiting blocks and the limiting blocks are fixedly connected to the mounting block, and the limiting blocks are used to prevent the PTC heater from displacing.
[0009] Furthermore, it is particularly preferred that a collection box is also included, which is slidably connected to the right side of the mounting base, and the collection box is used to collect the PTC heater after testing.
[0010] Beneficial effects: The sensor accurately detects the PTC heater's positioning, causing the cylinder to push the push plate forward. This push plate then precisely aligns the female and male connectors, eliminating the need for manual alignment of the heater's interfaces. This not only improves detection efficiency but also avoids alignment deviations caused by improper manual operation, ensuring accurate alignment.
[0011] By rotating the limiting plate on the rotating shaft, the elastic element is compressed, causing the limiting plate to press down to the magnet position on the right support frame. The magnet will firmly attract the limiting plate, preventing the female connector from unnecessary tilting or displacement due to the thrust of the cylinder during docking, thus ensuring the stability of the docking process and the reliability of the docking result.
[0012] The limiting block prevents the PTC heater from moving forward along with the push plate, thus limiting its movement and preventing the PTC heater from moving. Attached Figure Description

[0017] 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.
[0018] Example: A functional testing device for testing PTC ceramic heaters, such as... Figure 1-3As shown, the device includes a mounting base 1, a switch 101, a mounting block 2, a PTC heater 3, a female connector 301, a male connector 302, a cylinder 4, a push plate 5, and a sensor 6. The switch 101 is symmetrically arranged on the top front side of the mounting base 1. The mounting block 2 is fixedly connected to the mounting base 1. A sliding groove is formed in the middle of the front side of the mounting block 2. Sliding grooves are symmetrically arranged on the left and right sides of the mounting block 2. The PTC heater 3 is placed on the rear side of the mounting block 2. The female connector 301 is located on the front side of the PTC heater 3. The female connector 301 is placed in the central groove of the mounting block 2. The mounting base 1 is provided with the male connector 302, which is fixedly connected to the front side of the mounting base 1. Two cylinders 4 are fixedly connected to the mounting block 2. The telescopic rods of the cylinders 4 are fixedly connected to the push plates 5. The push plates 5 are slidably connected in the grooves symmetrically provided on the mounting block 2. The female connector 301 is placed in front of the push plates 5. The two push plates 5 are provided with sensors 6. The push plates 5 are used for pushing... The mounting block 2 is equipped with a female connector 301 and a male connector 302 for docking. The mounting block also includes a support frame 7, a rotating shaft 8, a limiting plate 9, elastic elements 10, and a magnet 11. The support frames 7 are symmetrically arranged on the mounting block 2 and are fixedly connected to the mounting block 2. The rotating shaft 8 is fixedly connected to the left side of the support frame 7. The limiting plate 9 is rotatably connected to the rotating shaft 8. The elastic elements 10 are symmetrically sleeved on the rotating shaft 8. One end of the elastic element 10 is fixedly connected to the support frame 7, and the other end of the elastic element 10... One end is fixedly connected to the limiting plate 9, and the magnet 11 is provided on the support frame 7 on the right side. The limiting plate 9 is used to prevent displacement during docking. It also includes an anti-slip pad 13, which is fixedly connected to the symmetrical sliding groove of the mounting block 2. The anti-slip pad 13 is used to increase friction and prevent the push plate 5 from shifting during movement. It also includes a collection box 15, which is slidably connected to the right side of the mounting base 1. The collection box 15 is used to collect the tested PTC heater 3.
[0019] When using the detection device, the operator first places the PTC heater 3 to be tested on the rear side of the mounting block 2. The female connector 301 on the PTC heater 3 is placed in the groove in the middle of the mounting block 2. Once the sensor 6 accurately detects that the PTC heater 3 is in place, it sends a signal to the control system, which drives the cylinder 4 to operate. The lifting rod of the cylinder 4 then pushes the push plate 5 on the mounting block 2 forward. Because the anti-slip pad 13 is provided in the groove on the mounting block 2, it prevents the push plate 5 from shifting during movement and also increases the friction, ensuring the stability of the movement. Thus, the push plate 5 drives the female connector 301 on the mounting block 2 forward until the female connector 301 and the male connector 302 are precisely connected. This eliminates the need for the operator to manually connect the heater interfaces, improving detection efficiency and avoiding connection deviations caused by improper manual operation, while ensuring the accuracy of the connection. When the sensor 6 detects that the interface has been successfully connected, The switch 101 will be automatically activated to perform a function test on the PTC heater 3. The detected values will appear on the display screen, and the operator will then compare them with standard values to determine if they are within a reasonable range. During the forward movement of the female connector 301 driven by the push plate 5, the operator needs to rotate the limiting plate 9 on the rotating shaft 8 clockwise. As the limiting plate 9 rotates, it will press against the elastic element 10, which is then in a compressed state. Subsequently, the operator will... 9. Press down to the position of the magnet 11 on the right support frame 7. At this time, the limiting plate 9 will be firmly attracted by the magnet 11, which prevents the female interface 301 from unnecessary tilting or displacement due to the thrust of the cylinder 4 during docking. This ensures the stability of the docking process and the reliability of the docking result. After the PTC heater 3 has finished testing, rotate the limiting plate 9 in the opposite direction. At this time, the elastic element 10 will reset the limiting plate 9 with the elastic element 10. Then, the operator needs to manually separate the docked female interface 301 from the male interface 302 and place the tested PTC heater 3 into the collection box 15 for collection, which facilitates collection and achieves efficient use of space.
[0020] like Figure 1 As shown, it also includes support feet 12. Multiple support feet 12 are fixedly connected to the bottom of the mounting base 1. The support feet 12 are used to support the overall device.
[0021] The support feet 12 ensure that the entire device is placed stably on the workbench, preventing operational errors or safety accidents caused by shaking or tilting of the device, and improving the stability of the device.
[0022] like Figure 1 As shown, it also includes a limiting block 14. The limiting block 14 is symmetrically provided on the mounting block 2. The limiting block 14 is fixedly connected to the mounting block 2. The limiting block 14 is used to prevent the PTC heater 3 from being displaced.
[0023] The limiting block 14 can prevent the PTC heater 3 from moving forward together with the push plate 5, thus limiting the movement of the PTC heater 3.
[0024] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
