Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone data line performance detection, in particular to a performance detection device for a mobile phone data line. Background Art

[0002] A mobile phone data cable is a cable used to connect a mobile phone to an external device (such as a computer, charger, etc.). Its main function is to achieve data transmission, such as transferring files (such as photos, videos, documents, etc.) in a mobile phone to a computer, or transferring data from a computer to a mobile phone. At the same time, it is also used for charging, allowing an external power source (such as a charger) to replenish the battery of the mobile phone.

[0003] In the prior art, the staff fixes the data line sample on the fixture and adds a certain load. During the test, the fixture swings left and right. After a certain number of times, the disconnection rate is checked, or it is done until the power fails. When the fixture swings left and right, it is difficult to accurately control the swing speed and the degree of bending of different parts of the data line. To detect multiple parts of the data line, the position of the fixture needs to be adjusted multiple times. Each adjustment of the position of the fixture takes time to re-fix the sample, adjust the load, etc., and the operation process is complicated. For example, when detecting the bending degree of different positions of a long data line, it may be necessary to frequently loosen the fixture, move the data line position, re-fix and adjust the load, which will greatly increase the time required for detection and reduce the overall detection efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a performance detection device for a mobile phone data line to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides a performance detection device for a mobile phone data cable, including a base plate, a first support plate, which is arranged on the top of the base plate; a second support plate, which is arranged on the base plate and has a height lower than that of the base plate, and a plurality of first support plates and second support plates are interconnected to form an elastic member, and the top of the second support plate is set to be a rounded corner; an electric telescopic rod, which is arranged below the base plate; an electromagnet, which is fixedly installed on the telescopic end of the electric telescopic rod; an iron block, which is fixedly installed on the leftmost first support plate and the rightmost second support plate, and a guide opening adapted to the iron block is opened on the base plate; a placement groove, which is opened on the top of the first support plate and has a U-shape.

[0006] Furthermore, a clamping block is provided on one side of the placement groove, two mounting rods are fixedly mounted on one side of the clamping block, circular rings are fixedly mounted on the outer walls of the mounting rods, and a reset spring is fixedly mounted between the circular ring and the first support plate.

[0007] Furthermore, a non-slip rubber layer is integrally formed on one side of the clamping block and on a side of the first support plate opposite to the clamping block.

[0008] Furthermore, a pull block is fixedly installed on the top of the clamping block, and the vertical cross-section of the pull block is set to be T-shaped.

[0009] Furthermore, a mounting block is fixedly installed at the bottom of the base plate, the fixed end of the electric telescopic rod is fixedly installed on the mounting block, the fixed end of the electric telescopic rod is externally sleeved with a reinforcement block, and the reinforcement block is fixedly installed at the bottom of the base plate.

[0010] Furthermore, a trapezoidal slider is fixedly installed at the bottom of the connection between the first support plate and the second support plate, a slide groove matched with the trapezoidal slider is opened on the bottom plate, and a ball is arranged inside the trapezoidal slider, and the ball is against the bottom of the slide groove.

[0011] Furthermore, the cross-sections of the trapezoidal sliding block and the sliding groove are both isosceles trapezoidal shapes that are narrow at the top and wide at the bottom.

[0012] Furthermore, the first support plate and the second support plate are both made of spring steel.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, after both ends of the mobile phone data cable are powered on, they are placed in the placement slot and fixed by the mounting rod, the reset spring and the clamping block. After the single chip microcomputer adjusts the telescopic end of the electric telescopic rod to be in place, the electromagnet is powered on to attract the iron block to move toward the center of the bottom plate, squeezing the elastic member formed by the first support plate and the second support plate to reduce the angle, so that the data line between the two plates is bent to detect the bending degree of each part. After the electromagnet is powered off, the elastic member made of spring steel is automatically reset, and the detection is repeated. If the power cannot be turned on during the detection, the data line is damaged. This method can detect multiple positions at the same time, reduce the detection time, and improve efficiency.

[0014] 2. In the present invention, the clamp block is combined with the mounting rod and the reset spring to stably clamp the mobile phone data cable. The data cable is placed on one side of the placement slot, and the clamp block fits the data cable under the elastic force of the reset spring and is fixed in the placement slot, ensuring that the data cable does not move when testing plugging, bending, and electrical performance, ensuring stable and accurate testing.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 6 , the present invention provides a technical solution: See also Figure 1-Figure 6 The present invention shows a performance detection device for a mobile phone data line, comprising a bottom plate 1, a first support plate 2, which is arranged on the top of the bottom plate 1; a second support plate 3, which is arranged on the bottom plate 1 and has a height lower than that of the bottom plate 1, and is formed by connecting a plurality of first support plates 2 and second support plates 3 to form an elastic member, and the top of the second support plate 3 is set to be rounded; an electric telescopic rod 4, which is arranged below the bottom plate 1; an electromagnet 5, which is fixedly mounted on the telescopic end of the electric telescopic rod 4; an iron block 6, which is fixedly mounted on the leftmost first support plate 2 and the rightmost second support plate 3, and a guide opening adapted to the iron block 6 is provided on the bottom plate 1; a placement groove 12, which is opened on the top of the first support plate 2 and has a U-shape.

[0019] After both ends of the mobile phone data cable are connected to the power supply, the staff places the mobile phone data cable on the placement slot 12, and with the help of the coordinated action of the installation rod 7, the reset spring 8 and the clamping block 9, the mobile phone data cable is firmly clamped. Then, the single-chip microcomputer is used to accurately control the telescopic end of the electric telescopic rod 4 to adjust it to the appropriate position. Then, the electromagnet 5 is energized. Since the iron block 6 is made of iron material, the magnetic force generated by the electromagnet 5 after being energized will exert suction on the iron block 6, prompting the two iron blocks 6 to move toward the center of the bottom plate 1. In the process of relative movement of the two iron blocks 6, the elastic member composed of the multiple first support plates 2 and the second support plates 3 will be squeezed, thereby causing the first support plate 2 and the second support plate 3 to be moved. The angle gradually becomes smaller, so that the mobile phone data cable located between the two first support plates 2 will bend. In this way, the bending degree of each part of the mobile phone data cable can be detected. When the electromagnet 5 is powered off, its suction force on the iron block 6 disappears. In view of the fact that the first support plate 2 and the second support plate 3 are made of only spring steel, the elastic member formed will automatically return to its initial state. This cycle is repeated to achieve continuous detection of the bending degree of the mobile phone data cable. If power cannot be supplied during the detection process, it indicates that the data cable is damaged. This detection method can detect the bending degree of multiple positions of the data cable at the same time, effectively reducing the time consumed in detection and greatly improving the overall detection efficiency.

[0020] See also Figure 1 A clamping block 9 is provided on one side of the placement groove 12, and two mounting rods 7 are fixedly installed on one side of the clamping block 9. Rings are fixedly installed on the outer walls of the mounting rods 7, and a return spring 8 is fixedly installed between the rings and the first support plate 2.

[0021] The clamp block 9 can stably clamp the mobile phone data cable through the combined design of the mounting rod 7 and the reset spring 8. When the data cable is placed on one side of the placement slot 12, the clamp block 9 can fit the data cable tightly under the elastic force of the reset spring 8 and fix it in the placement slot 12. In this way, when performing performance testing, such as testing the plug-in performance, bending performance or electrical performance of the data cable, the data cable will not move at will, ensuring the stability and accuracy of the testing process.

[0022] Due to the presence of the reset spring 8, the clamping block 9 can automatically adjust the clamping force according to the size of the data cable. For thinner data cables, the reset spring 8 will not be over-compressed to avoid damage to the data cable; for thicker data cables, the reset spring 8 can be appropriately compressed and still provide sufficient clamping force. This adaptive characteristic enables the detection device to be applicable to mobile phone data cables of various specifications, thereby improving the versatility of the device.

[0023] See also Figure 5One side of the clamping block 9 and the side of the first support plate 2 opposite to the clamping block 9 are integrally formed with an anti-slip rubber layer 11.

[0024] The anti-skid rubber layer 11 on one side of the clamp block 9 and the opposite side of the first support plate 2 can greatly increase the friction between the clamp block 9 and the mobile phone data cable. During the detection process, the data cable may be subjected to various external forces. For example, when performing plug-in and unplug performance tests, it is necessary to simulate frequent plug-in and unplug actions; when performing bending tests, the data cable will also be subjected to tension and torsion. The anti-skid rubber layer 11 can effectively prevent the data cable from sliding under the action of these external forces, ensuring that the data cable always remains in the correct position, thereby ensuring the accuracy of the detection results. Rubber is a relatively soft material. When the anti-skid rubber layer 11 contacts the data cable, it can prevent the hard surfaces of the clamping block 9 and the first supporting plate 2 from directly scratching or squeezing the data cable. Especially for some data cables with soft outer skin or easily scratched outer skin, the anti-skid rubber layer 11 plays a very good protective role, preventing the outer skin of the data cable from being damaged or worn due to friction with the surface of the device during the fixing process or the detection process, thereby extending the service life of the data cable.

[0025] See also Figure 5 A pull block 10 is fixedly installed on the top of the clamp block 9, and the vertical cross-section of the pull block 10 is set to be T-shaped.

[0026] The vertical cross-section of the pull block 10 is T-shaped, and this design provides a larger gripping area. When the user needs to open the clamp 9 to place or remove the mobile phone data cable, the T-shaped pull block 10 allows the user to hold it more conveniently with his fingers. Compared with the case where there is no pull block 10 or the shape of the pull block 10 is not convenient to hold, the T-shaped pull block 10 makes the operation easier, especially in the scenario where the data cable needs to be frequently replaced for testing, which can effectively improve the work efficiency.

[0027] See also Figure 2 A mounting block 16 is fixedly installed at the bottom of the base plate 1 , and the fixed end of the electric telescopic rod 4 is fixedly installed on the mounting block 16 . A reinforcement block 17 is sleeved on the outside of the fixed end of the electric telescopic rod 4 , and the reinforcement block 17 is fixedly installed at the bottom of the base plate 1 .

[0028] By fixing the mounting block 16 at the bottom of the base plate 1 to connect the fixed end of the electric telescopic rod 4, a stable mounting base is provided for the electric telescopic rod 4. Such a design can ensure that the electric telescopic rod 4 will not be displaced due to its own vibration or external force during operation, thereby ensuring that the electric telescopic rod 4 can accurately perform telescopic actions in a preset manner.

[0029] The reinforcement block 17 is sleeved on the outside of the fixed end of the electric telescopic rod 4 and fixedly installed on the bottom of the base plate 1, which further enhances the fixing effect of the electric telescopic rod 4. When the electric telescopic rod 4 is frequently extended or subjected to a large external force, the reinforcement block 17 can share part of the force to prevent the connection between the fixed end of the electric telescopic rod 4 and the base plate 1 from loosening, thereby extending the service life of the electric telescopic rod 4 and ensuring the stability and reliability of the entire device.

[0030] See also Figure 4 A trapezoidal slider 13 is fixedly installed at the bottom of the connection between the first support plate 2 and the second support plate 3. A slide groove 14 adapted to the trapezoidal slider 13 is opened on the bottom plate 1. A ball 15 is arranged inside the trapezoidal slider 13, and the ball 15 is against the bottom of the slide groove 14.

[0031] The trapezoidal slider 13 at the bottom of the connection between the first support plate 2 and the second support plate 3 is matched with the slide groove 14 on the bottom plate 1. This structural design enables the first support plate 2 and the second support plate 3 to slide smoothly relative to the bottom plate 1. When the detection device performs operations such as bending the mobile phone data cable, this sliding can ensure that the data cable can be bent in a predetermined manner, simulating a real usage scenario, such as simulating the situation where the data cable is bent in daily use.

[0032] The ball bearings 15 disposed inside the trapezoidal slider 13 abut against the bottom of the slide groove 14, and the ball bearings 15 can convert the sliding friction between the slider and the slide groove 14 into rolling friction. The friction force of rolling friction is much smaller than that of sliding friction, which makes the sliding of the first support plate 2 and the second support plate 3 smoother, reduces the jamming phenomenon caused by excessive friction, and improves the flexibility and efficiency of the device operation.

[0033] See also Figure 4 The cross sections of the trapezoidal slider 13 and the slide groove 14 are both isosceles trapezoidal shapes that are narrow at the top and wide at the bottom.

[0034] The cross-section of the trapezoidal slider 13 and the slide groove 14 is an isosceles trapezoid that is narrow at the top and wide at the bottom. This shape design allows the slider to slide in the slide groove 14 only in a specific direction. During the operation of the device, when the first support plate 2 and the second support plate 3 move relative to the base plate 1, the trapezoidal slider 13 will naturally be guided along the shape of the slide groove 14, effectively preventing the slider from deviating to the left or right or falling out of the slide groove 14 during the sliding process, thereby providing precise guidance for the movement of the device.

[0035] The narrow upper and wide lower shape also enhances the positioning stability of the slider in the slide groove 14. When the device is disturbed by external vibration or the force generated during the data line performance detection process, the trapezoidal slider 13 will be more firmly located in the slide groove 14 due to its shape characteristics. For example, when the data line is bent, a certain lateral force may be generated. The isosceles trapezoidal slider and the slide groove 14 structure can better resist these lateral forces, ensure the relative position stability of the first support plate 2 and the second support plate 3, and ensure the accuracy of the detection operation.

[0036] See also Figure 1-2 The first support plate 2 and the second support plate 3 are both made of spring steel.

[0037] Spring steel has excellent elasticity. In the mobile phone data cable performance testing device, when the data cable is subjected to a bending test, the first support plate 2 and the second support plate 3 can use their own elasticity to simulate real bending conditions. For example, when performing multiple small-angle bending or large-angle bending operations, the support plate made of spring steel can elastically deform like a spring and return to its original shape after the bending force disappears. This elastic deformation characteristic can effectively prevent the support plate from being damaged due to excessive bending, and can also provide a softer bending environment for the data cable, which is more in line with the bending conditions that the data cable may encounter in actual usage scenarios.

[0038] The toughness of spring steel is also very high, which means that when subjected to large impact force or repeated stress, the first support plate 2 and the second support plate 3 are not prone to brittle fracture. During the operation of the detection device, impact force may be generated due to the sudden start or stop of power equipment such as motors, or accumulated stress may be generated during frequent bending operations. The toughness of spring steel can ensure that the support plates can withstand these forces, ensure the stability and durability of the device, and thus ensure that the data cable performance detection work can proceed smoothly.

[0039] Working principle: After both ends of the mobile phone data cable are connected to the power supply, the staff places the mobile phone data cable on the placement slot 12, and with the help of the coordinated action of the installation rod 7, the reset spring 8 and the clamping block 9, the mobile phone data cable is firmly clamped. Then, the single-chip microcomputer is used to accurately control the telescopic end of the electric telescopic rod 4 to adjust it to the appropriate position. Then, the electromagnet 5 is energized. Since the iron block 6 is made of iron material, the magnetic force generated by the electromagnet 5 after being energized will exert suction on the iron block 6, prompting the two iron blocks 6 to move toward the center of the bottom plate 1. In the process of relative movement of the two iron blocks 6, the elastic member composed of multiple first support plates 2 and second support plates 3 will be squeezed, thereby causing the first support plate 2 and the second support plate 3 to move. 3 gradually becomes smaller, so that the mobile phone data cable located between the two first support plates 2 will bend. In this way, the bending degree of each part of the mobile phone data cable can be detected. When the electromagnet 5 is powered off, its suction force on the iron block 6 disappears. Since the material of the first support plate 2 and the second support plate 3 is only spring steel, the elastic member formed will automatically return to its initial state. This cycle is repeated to achieve continuous detection of the bending degree of the mobile phone data cable. If power cannot be supplied during the detection process, it indicates that the data cable is damaged. This detection method can detect the bending degree of multiple positions of the data cable at the same time, effectively reducing the time consumed in detection and greatly improving the overall detection efficiency.

[0040] The rounded corner design at the top of the second support plate 3 can prevent the data cable from being scratched or damaged. When the data cable is placed on the support plate or moves during the detection process, the rounded corner can prevent the data cable from contacting the sharp edge of the top of the support plate. Compared with the right-angle edge, the rounded corner has no sharp corners, reducing the risk of scratching and wearing the outer skin of the data cable, and protecting the appearance of the data cable and the integrity of the internal circuit.

[0041] The clamp block 9 can stably clamp the mobile phone data cable through the combined design of the mounting rod 7 and the reset spring 8. When the data cable is placed on one side of the placement slot 12, the clamp block 9 can fit the data cable tightly under the elastic force of the reset spring 8 and fix it in the placement slot 12. In this way, when performing performance testing, such as testing the plug-in performance, bending performance or electrical performance of the data cable, the data cable will not move at will, ensuring the stability and accuracy of the testing process.
