Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire testing fixtures, and in particular to a testing fixture for electric blanket wires. Background Technology
[0002] In today's electric blanket manufacturing industry, the safety and performance of electric blankets, as a widely used household heating device, are of paramount importance. Electric blankets typically incorporate specially designed soft cord heating elements woven or sewn into the blanket, relying on electricity to generate heat for warmth. Since they operate on a 220V AC power supply, performance testing of the electric blanket's wiring becomes an indispensable and crucial step before the product leaves the factory.
[0003] The test fixture mainly consists of a base, a test probe bed, a control panel, and electrical connection components. The base provides stable support for the entire fixture, ensuring the stability of the testing process. The test probe bed contains numerous carefully arranged test probes, whose layout is adapted to the interface of the electric blanket cable, allowing for precise contact with the cable pins. The control panel is equipped with various operation buttons and display instruments, allowing operators to easily set test parameters, start the test process, and intuitively read test results. During operation, the electric blanket cable is connected to the test fixture, and the corresponding test commands are input through the control panel. The electrical connection components then transmit power and test signals to the test probe bed. The probes contact the cable pins and are energized, detecting various performance indicators of the cable, such as conductivity, insulation, and resistance. The test results are fed back to the display instruments on the control panel in real time, thereby determining whether the cable meets quality standards.
[0004] In the current practical application scenarios of electric blanket wire testing fixtures, some fixtures have revealed serious design flaws in the crucial step of connecting the needle bed and the wire, namely, the lack of necessary guiding mechanisms. This deficiency results in a lack of precise guidance during the connection process, forcing operators to rely solely on experience and visual judgment. This not only greatly increases the difficulty of connection and prolongs the test preparation time, but also easily leads to poor contact between the test probe and the wire pins due to connection deviations, resulting in inaccurate test results and misjudgments, seriously affecting the efficiency and reliability of the test. Therefore, an electric blanket wire testing fixture is proposed to solve the above problems. Utility Model Content

[0031] 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.
[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an electric blanket wire testing fixture, including a base 1. The base 1 ensures the stability of the testing fixture during use and prevents the instability of the base 1 from affecting the accuracy of the test results. A guide frame 2 is fixedly connected to the top of the base 1. The guide frame 2 provides guidance for the sliding of relevant components during the entire testing process, ensuring that the components can move accurately along the predetermined direction, thus ensuring the smooth progress of the test. A detection seat 3 is fixedly connected to the top of the base 1. The detection seat 3 is one of the core components for testing the electric blanket wire, used to connect with the wire and perform related testing operations. Two indicator lights 4 are fixedly connected to the top of the detection seat 3. The indicator lights 4 can intuitively display the continuity status of the wire during the test. When the wire is connected, the indicator lights 4 light up; when it is not connected, the indicator lights 4 turn off, which facilitates the testers to quickly obtain the test results and promptly determine whether there is a problem with the wire. At the same time, the detection seat 3 has built-in detection components that can detect the conductivity, insulation, and resistance value of the wire, etc.
[0033] The test base 3 has a circuit 5 inside, which serves as the test object simulating the wire of an electric blanket. During the test, it undergoes various performance tests. The guide frame 2 has a test component on the outside for testing the performance of the circuit 5. The guide frame 2 has a sliding block 6 inside, which can slide flexibly within the guide frame 2. The sliding of the sliding block 6 achieves precise docking between the circuit 5 and the test base 3, avoiding the inaccuracies and instability that occur with manual docking, thus improving the accuracy and efficiency of docking. The sliding block 6 has two limiting clips 9 inside, which can slide within the sliding block 6. The main function of the two limiting clips 9 is to limit and fix the circuit 5, ensuring that the circuit 5 will not shift or loosen excessively during the test, thus ensuring the reliability of the test. The two limiting clips 9 are fixedly connected to telescopic columns 7 on opposite sides. The telescopic columns 7 provide a telescopic support structure for the sliding of the limiting clips 9, allowing the limiting clips 9 to be adjusted appropriately according to the thickness of the circuit 5.
[0034] Springs 8 are fitted on the outside of both telescopic columns 7. Springs 8 play an important role in fixing the line 5 in the process of limiting clamp 9. Springs 8 can continuously push the limiting clamp 9, so that the limiting clamp 9 tightly clamps the line 5, which further improves the stability of fixing the line 5. Sliding blocks 10 are fixedly connected to both ends of sliding block 1 6. Sliding block 10 cooperates with guide frame 2, so that sliding block 1 6 can slide more stably in guide frame 2. At the same time, it also provides a connection point for subsequent operation to limit the position of sliding block 1 6. A limiting component is provided on the outside of guide frame 2. The limiting component includes fixed column 11. The outside of fixed column 11 is fixedly connected to the outside of sliding block 2 10.
[0035] The external fixed connection of the detection seat 3 is a fixed post 2 12, which is also part of the limiting component and works together with the fixed post 1 11. The external sliding connection of the guide frame 2 is a limiting block 13, which can slide outside the guide frame 2. When the sliding block 1 6 is aligned with the detection seat 3, the sliding limiting block 13 connects it with the fixed post 1 11 and the fixed post 2 12, thereby limiting the position of the sliding block 1 6 and providing stable conditions for subsequent tensile testing. The external sliding connection of the fixed post 1 11 and the fixed post 2 12 is inside the limiting block 13. The external of the line 5 is in contact with the adjacent side of the two limit clamps 9. The opposite side of the two telescopic posts 7 is fixedly connected to the inside of the sliding block 1 6. The external sliding connection of the sliding block 2 10 is inside the guide frame 2. One end of the two springs 8 is fixedly connected to the opposite end of the two limit clamps 9, and the other end of the two springs 8 is fixedly connected to the inside of the sliding block 1 6.
[0036] Reference Figure 1 , Figure 2 and Figure 4The testing component includes a sliding block 3 14, which is externally slidably connected to the inside of the guide frame 2. The sliding of the sliding block 3 14 within the guide frame 2 is a key step in performing a tensile test on the line 5. By sliding the sliding block 3 14, the line 5 is stretched, thereby testing the tensile strength of the line 5. The sliding block 3 14 has two limiting blocks 2 15 internally connected. The two limiting blocks 2 15 can slide within the sliding block 3 14 to further fix the line 5, ensuring that the line 5 will not fall out of the sliding block 3 14 during the stretching process, thus ensuring the accuracy of the test. The adjacent sides of the two limiting blocks 2 15 are in contact with the outside of the line 5. The top of each of the two limiting blocks 2 15 is fixedly connected to a connecting post 16, which is used to connect the limiting blocks 2 15 and the threaded post 17. By rotating the threaded post 17, the limiting blocks 2 15 can be slid within the sliding block 3 14, thereby clamping and releasing the line 5.
[0037] The sliding block 3 14 has two threaded posts 17 internally connected by threads. The threaded connection between the threaded posts 17 and the sliding block 3 14 allows its rotation to be converted into the linear motion of the limiting block 2 15, thus facilitating the adjustment of the fixing degree of the limiting block 2 15 to the line 5. Both ends of the sliding block 3 14 are fixedly connected to connecting blocks 19. The guide frame 2 is externally fixedly connected to two fixing plates 18, and cylinders 20 are fixedly connected to the outside of the two fixing plates 18. The fixing plates 18 provide a fixed installation position for the cylinders 20, ensuring the stability of the cylinders 20 during operation. The cylinders 20, as a power source, can provide stable pulling force to drive the connecting blocks 19 to slide inside the guide frame 2, thereby realizing the pulling operation of the line 5. The driving end of the cylinders 20 is fixedly connected to the front end of the connecting blocks 19, and the outside of the connecting blocks 19 is slidably connected to the inside of the guide frame 2. The outside of the two threaded posts 17 is rotatably connected to the inside of the two connecting posts 16 respectively. The top of the sliding block 3 14 has an inlet and outlet groove, which facilitates the insertion and removal of the line 5, making the testing operation more convenient.
[0038] Working principle: When the inspector needs to test the wires of the electric blanket, the outer part of the wire 5 is first slid into the two limiting clamps 9. At this time, the two limiting clamps 9 will slide inside the sliding block 6. When the outer part of the wire 5 is completely slid into the two limiting clamps 9, the two springs 8 will continuously push the limiting clamps 9 to restrict the position of the wire 5. At this time, the front end of the wire 5 can be precisely connected with the test seat 3 by sliding the sliding block 6. This avoids damage to the connector of the wire 5 and the test seat 3 caused by manual connection, or the connection being unstable and affecting the subsequent test results. After connection, the fixing post 11 and fixing post 2 12 are slid into the limiting block 13 by sliding the limiting block 13. At this time, the position of the sliding block 6 is restricted to facilitate the subsequent tensile test.
[0039] After the position of sliding block 16 is fixed, slide the outside of line 5 into the side of the two limiting blocks 2 15. Then, by rotating the threaded column 17, the limiting block 2 15 slides inside the sliding block 3 14, thus limiting the position of line 5. At this time, the cylinder 20 can be activated. The cylinder 20 will drive the connecting block 19 to slide inside the guide frame 2, thereby causing the sliding block 3 14 to slide inside the guide frame 2 to pull the line 5. The indicator light 4 will indicate whether the connection is established, thus detecting the tensile strength of line 5.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
