Technical Field
[0001] The utility model relates to the technical field of test cables, in particular to a large-volume test cable plugging and unplugging device. Background Art
[0002] As an important connection element in electronic equipment and systems, cables are widely used in aerospace, automobile manufacturing, electronic equipment production, petrochemical, machinery manufacturing, wires and cables, textiles, fibers, plastics, rubber, ceramics, food, pharmaceutical packaging and other fields. These industries have extremely high requirements for the quality and reliability of cables. With the continuous development of electronic technology and the trend of miniaturization and lightweight of products, the connection quality and durability of cables have become key factors affecting the overall performance of products. Therefore, the demand for testing the plug-in performance of cables is increasing, requiring test equipment to be able to complete large-scale testing efficiently and accurately.
[0003] In traditional testing, the plug-in and unplug tests of cables often rely on multiple manual operations, which is not only time-consuming and labor-intensive, but also difficult to ensure the consistency and accuracy of each test result. Especially in large-scale testing, the low efficiency of manual testing that requires multiple operations has become a bottleneck restricting production progress; existing testing equipment can often only adapt to cables of specific specifications and types. For a wide variety of cable products, the fixture needs to be replaced frequently during testing, which increases the difficulty and cost of testing. Summary of the invention
[0004] (I) Technical problems to be solved: Existing technologies often rely on multiple manual operations, which is not only time-consuming and labor-intensive, but also difficult to ensure the consistency and accuracy of each test result. Especially in large-scale testing, the low efficiency of manual testing that requires multiple operations has become a bottleneck restricting production progress; existing testing equipment can often only adapt to cables of specific specifications and types. For a wide variety of cable products, it is necessary to frequently replace fixtures and test interface boards during testing, which increases the difficulty and cost of testing. The utility model provides a large-scale testing cable plugging and unplugging device, which uses a limiting device to limit a large number of cables at the same time, so that all cables are at the same distance. The staff only needs to complete the plugging and unplugging once, and the tool for realizing the limit is adjustable, which can flexibly realize the testing of various types of cables without the need for frequent replacement of fixtures.
[0005] (2)Technical solution: To achieve the above object, the utility model provides the following technical solution: A large-batch test cable plugging and unplugging device, including an upper limit plate and a lower limit plate. An array of upper limit holes are provided on the horizontal surface of the upper limit plate. The upper limit holes are of the same size, and the number is greater than or equal to two. The size of each upper limit hole is larger than the size of the plug of the cable to be tested. A lower limit plate is installed below the upper limit plate. The horizontal surface of the lower limit plate is hollowed out with lower limit holes corresponding one by one to the positions of the upper limit holes. The number of the lower limit holes is the same as that of the upper limit holes. Magnets are evenly distributed on the upper surface of the lower limit plate. The upper limit plate is made of a magnetic material. The lower surface of the upper limit plate and the upper surface of the lower limit plate are tightly connected by magnetic force. When the upper limit plate is adsorbed by the lower limit plate through the magnets, it still retains a degree of freedom of movement parallel to the lower limit plate.
[0006] Preferably, the magnets evenly cover the upper surface of the lower limit plate, so that the upper surface of the lower limit plate remains horizontal.
[0007] Preferably, handles are designed on both sides of the lower limit plate. The handles are arc-shaped, parallel to the horizontal plane, and the height in the vertical direction does not exceed the thickness of the lower limit plate.
[0008] Preferably, support rods are designed at both ends of the handle. The support rods can move in the vertical direction through the threads on the outer surface.
[0009] Preferably, the thickness of the upper limit plate is less than the thickness of the lower limit plate.
[0010] Preferably, the four surfaces of the upper limit hole are respectively cut off towards the surroundings to form grooves.
[0011] Preferably, left and right fixing plates and upper and lower fixing plates are respectively installed around the lower limit plate. The number of both the left and right fixing plates and the upper and lower fixing plates is one. The left and right fixing plates and the upper and lower fixing plates are perpendicular to each other. The left and right fixing plates are installed on the left or right surface of the lower limit plate. The upper and lower fixing plates are installed on the upper or lower surface of the lower limit plate. Threaded holes are provided on both the left and right fixing plates and the upper and lower fixing plates. The positions of the threaded holes are designed to be higher than the lower limit plate but lower than the upper surface of the upper limit plate. Threaded push rods are installed in the threaded holes. The threaded push rods have a coaxial degree of freedom of movement in the threaded holes.
[0012] Preferably, the left and right fixing plates and the upper and lower fixing plates are fixedly connected to the surface of the lower limit plate by welding.
[0013] (3) Beneficial effects: Compared with the prior art, the utility model provides a large-batch test cable plugging and unplugging device, which has the following beneficial effects:
[0014] 1. A large-batch test cable plugging and unplugging device is divided into an upper limit plate and a lower limit plate. The upper limit plate is made of magnetic material, and magnets are evenly distributed on the upper surface of the lower limit plate, so that the upper and lower limit plates are firmly attached to each other by magnetic force. When the staff needs to use the device to detect the plugging and unplugging of the cable to be tested, first align the upper limit hole and the lower limit hole inside the upper limit plate and the lower limit plate to form a channel larger than the plug of the cable to be tested. Then, place the plug end of the cable to be tested into the channel. After all the cables to be tested are placed, the operator slides the upper limit plate to adjust the position between the upper and lower limit plates, thereby changing the size of the limit channel and clamping and fixing the cables to be tested, making them arranged in an array, and the distance between adjacent cables is equal. Compared with the prior art, the cables to be tested fixed in this way are arranged in an array and the adjacent distances are equal. Therefore, only by aligning one of the plugs with the detection device, the plugging and unplugging tests of a large number of cables can be realized.
[0015] 2. A large-batch test cable plugging and unplugging device is respectively installed with left and right fixing plates and upper and lower fixing plates around the lower limit plate. The number of the left and right fixing plates and the upper and lower fixing plates is one each, and the left and right fixing plates and the upper and lower fixing plates are perpendicular to each other; the left and right fixing plates are installed on the left or right surface of the lower limit plate, and the upper and lower fixing plates are installed on the upper or lower surface of the lower limit plate; threaded holes are provided on both the left and right fixing plates and the upper and lower fixing plates, and the positions of the threaded holes are designed to be higher than the lower limit plate but lower than the upper surface of the upper limit plate; threaded push rods are installed in the threaded holes, and the threaded push rods have a coaxial movement freedom in the threaded holes. The user can adjust the movement of the threaded push rods by threads, use the threaded push rods to push the upper limit plate, and limit the upper limit plate. During the plugging and unplugging detection process, the two sides of the upper limit hole naturally clamp the cable to be tested, and the other two sides are pushed tightly by the threaded push rods to ensure that the cable to be tested is firmly fixed inside the limit hole; when the detection is over, just rotate the threaded push rods in the reverse direction to make the upper limit plate regain the movement freedom, so as to easily loosen the cable to be tested.
[0016] 3. A large-batch test cable plugging and unplugging device uses the positions of the movable upper limit holes in the left-right direction and the up-down direction to limit the cables to be tested. Therefore, this device is applicable to different cables to be tested. As long as the cable to be tested can be placed into the limiting channel, the movable upper limit plate can be used to clamp it. Therefore, different from the existing test equipment which often can only be adapted to specific specifications and types of cables, for a wide variety of cable products, it is necessary to frequently replace the fixtures and test interface boards during testing, increasing the difficulty and cost of testing. This device can flexibly implement the testing of various types of cables without frequently replacing the fixtures. Brief Description of the Drawings

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0027] As shown Figure 1-2 in the figure, the large-batch test cable plugging and unplugging device is specifically an auxiliary device for batch test equipment. In this embodiment, the batch test uses a power connection module 01 as shown Figure 8 in the figure. The upper surface of the power connection module 01 has an array of test sockets. It is necessary to simultaneously insert multiple cable plugs (USB plugs are used in this embodiment) into the upper sockets 011 of the power connection module 01. This test can be a large-current charging test, etc. When the power connection module 01 is powered on, each plug needs to be inserted to a set depth simultaneously.
[0028] The large-batch test cable plugging and unplugging device includes an upper limit plate 1 and a lower limit plate 2. The horizontal surface of the upper limit plate 1 is provided with upper limit holes 101 distributed in an array. The upper limit holes 101 are of the same size, and the number is greater than or equal to two. The size of each upper limit hole 101 is larger than the size of the plug of the cable to be tested. A lower limit plate 2 is installed below the upper limit plate 1. The horizontal surface of the lower limit plate 2 is hollowed out and designed with lower limit holes 201 corresponding to the positions of the upper limit holes 101 one by one. The number of the lower limit holes 201 is the same as that of the upper limit holes 101. Magnets 3 are evenly distributed on the upper surface of the lower limit plate 2. The upper limit plate 1 is made of a magnetic material. The lower surface of the upper limit plate 1 is tightly connected to the upper surface of the lower limit plate 2 by magnetic force. When the upper limit plate 1 is adsorbed by the lower limit plate 2 through the magnets 3, it still retains a degree of freedom of movement parallel to the lower limit plate 2, so that the user can slide the upper limit plate 1 in the horizontal direction. This device uses the position of the upper limit holes 101 in the left-right direction and the up-down direction to limit the cable to be tested. Therefore, this device is applicable to different cables to be tested. As long as the cable to be tested can be placed in the limit channel, the upper limit plate 1 can be moved to clamp it. Therefore, compared with the existing test equipment, which often can only be adapted to specific specifications and types of cables, for a variety of cable products, it is necessary to frequently replace the fixture and the test interface board during testing, increasing the difficulty and cost of testing. This device can flexibly realize the testing of various types of cables without frequently replacing the fixture.
[0029] As shown Figure 1-2 in the figure, the magnets 3 evenly cover the upper surface of the lower limit plate 2, keeping the upper surface of the lower limit plate 2 horizontal, ensuring that when clamping the cable to be tested, all cables to be tested are evenly stressed.
[0030] As shown Figure 1-2As shown, handles 4 are designed on both sides of the lower limit plate 2. The handles 4 are arc-shaped, parallel to the horizontal plane, and their height in the vertical direction does not exceed the thickness of the lower limit plate 2 to avoid hindering the movement of the upper limit plate 1. Support rods 9 are designed at both ends of the handle 4. The support rods 9 can move in the vertical direction through the threads on their outer surfaces. During use, the support rods 9 can lift the device above the placement platform, allowing the plug end of the cable under test to extend below the lower limit plate 2.
[0031] As Figure 1-2 shown, the thickness of the upper limit plate 1 is less than that of the lower limit plate 2, so that when the upper limit plate 1 clamps the cable under test, the cable under test will not tilt.
[0032] As Figure 3 shown, the four surfaces of the upper limit hole 101 are respectively cut off towards the surroundings to form grooves, reducing the contact area between the cable under test and the upper limit hole 101 when it is clamped, increasing the pressure, and making it more stable.
[0033] As Figures 4-6 shown, left and right fixing plates 5 and upper and lower fixing plates 6 are respectively installed around the lower limit plate 2. The number of both the left and right fixing plates 5 and the upper and lower fixing plates 6 is one, and the left and right fixing plates 5 and the upper and lower fixing plates 6 are perpendicular to each other. The left and right fixing plates 5 are installed on the left or right surface of the lower limit plate 2, and the upper and lower fixing plates 6 are installed on the upper or lower surface of the lower limit plate 2. Threaded holes 7 are provided on both the left and right fixing plates 5 and the upper and lower fixing plates 6. The position of the threaded holes 7 is designed to be higher than the lower limit plate 2 but lower than the upper surface of the upper limit plate 1. Threaded push rods 8 are installed in the threaded holes 7, and the threaded push rods 8 have freedom of coaxial movement in the threaded holes 7. The user can adjust the movement of the threaded push rods 8 by threads, use the threaded push rods 8 to push the upper limit plate 1, and limit the upper limit plate 1. During the plug and unplug detection process, both sides of the upper limit hole 101 naturally clamp the cable under test, while the other two sides are pushed tight by the threaded push rods 8, ensuring that the cable under test is firmly fixed inside the limit hole. When the detection is over, just rotate the threaded push rods 8 in the reverse direction to make the upper limit plate 1 regain the freedom of movement, thus easily loosening the cable under test.
[0034] As Figures 4-6 shown, the left and right fixing plates 5 and the upper and lower fixing plates 6 are fixedly connected to the surface of the lower limit plate 2 by welding.
[0035] As Figure 7As shown, during specific use, the staff first align the upper limit hole 101 inside the upper limit plate 1 with the lower limit hole 201 inside the lower limit plate 2 to form a channel larger than the plug of the cable to be tested. Subsequently, the plug end of the cable to be tested is placed inside the channel. After all the cables to be tested are placed, the operator slides the upper limit plate 1 to adjust the position between the upper and lower limit plates 2, thereby changing the size of the limit channel to clamp and fix the cables to be tested, making them present an array distribution, and the distance between adjacent cables is equal. Compared with the prior art, the cables to be tested fixed in this way are in an array distribution and the adjacent distances are equal. Therefore, only by aligning one of the plugs with the corresponding socket 011 in the power connection module 01 can the plug and unplug test of a large number of cables be realized.
[0036] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.
[0037] The above description is only the preferred embodiment of the present application and the explanation of the applied technical principle. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features with similar functions disclosed in the present application.
