Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to a micro capacitor contact positioning auxiliary fixture for coaxial cable testing. Background Technology

[0002] In the field of electronic equipment manufacturing and R&D, coaxial cables are a key component widely used in high-frequency signal transmission. The accurate testing of their performance is crucial. As one of the important parameters of coaxial cables, the accurate measurement of this parameter plays a decisive role in evaluating the signal transmission quality, stability, and electromagnetic compatibility of coaxial cables.

[0003] With the rapid development of electronic technology, the application scenarios of coaxial cables are becoming increasingly diversified. This has led to a diversified trend in the specifications and dimensions of coaxial cables, ranging from ultra-fine coaxial cables used in consumer electronics to relatively thick coaxial cables used in industrial equipment and communication base stations. The diameter range of cables is quite large. However, existing miniature capacitor contact positioning auxiliary fixtures can often only be adapted to coaxial cables of specific sizes. Some fixtures are designed according to cables of a certain standard diameter. When encountering cables with slightly different diameters, they cannot be accurately positioned and tested. Therefore, we propose a miniature capacitor contact positioning auxiliary fixture for coaxial cable testing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Existing miniature capacitive contact positioning auxiliary fixtures can often only be adapted to coaxial cables of a specific size. Some fixtures are designed for cables of a certain standard diameter. When encountering cables with slightly different diameters, they cannot be accurately positioned and tested.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A coaxial cable testing microcapacitor contact positioning auxiliary fixture includes a coaxial cable, and a connecting component is provided on the periphery of the coaxial cable;

[0007] The connecting component includes a ring test plate and an auxiliary fixture body. One end of the ring test plate is connected to the auxiliary fixture body through a connecting mechanism. A test mechanism is provided inside the ring test plate and the auxiliary fixture body.

[0008] The connecting mechanism includes a first slot opened at the upper end of the auxiliary fixture body. A rectangular box is provided on the outer wall of the auxiliary fixture body. A second slot is provided inside the rectangular box. Two trapezoidal screw rods are rotatably connected between the left and right inner walls of the second slot. The two trapezoidal screw rods in the second slot are threadedly connected to a moving plate. The moving plate is slidably connected to the inner walls on both sides of the second slot. Multiple connecting rods are fixedly connected to the end of the moving plate near the adjacent first slot.

[0009] The testing mechanism includes a limiting block fixedly connected to the lower end of the annular test plate, and the limiting block is provided with multiple limiting grooves.

[0010] Furthermore, the annular test plate and the auxiliary fixture body are rotatably connected at the other end.

[0011] Furthermore, one end of one of the trapezoidal lead screws extends to the outside of the rectangular box and is fixedly connected to a knob.

[0012] Furthermore, each of the two trapezoidal lead screws in the second slot is equipped with a transmission wheel, and the transmission wheels are connected by a synchronous transmission belt.

[0013] Furthermore, the limiting block is adapted to be connected with the first slot.

[0014] Furthermore, the limiting groove is provided in several groups from top to bottom, and each group of limiting grooves cooperates with the connecting rod through the docking depth of the limiting block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting the limiting groove and multiple trapezoidal lead screws, the ring test plate and the auxiliary fixture body can adapt to coaxial cables of different sizes. The distance between the ring test plate and the auxiliary fixture body can be adjusted according to the actual situation of different cables. This operation method not only improves the convenience of testing, but also ensures that the fixing and release of cables can be completed quickly and stably during the testing of cables of different sizes.

[0017] 2. Insert the limiting block of the ring test plate into the first slot of the auxiliary fixture body, and turn the knob to rotate the trapezoidal lead screw. Since the two trapezoidal lead screws in the second slot are connected by a synchronous transmission belt, the rotation of the knob will drive multiple trapezoidal lead screws to rotate synchronously, thereby moving the moving plate and driving multiple connecting rods to move into the corresponding limiting slots to complete the connection. When disassembly is required, turn the knob. This design greatly improves the efficiency of cable replacement and testing, and is especially suitable for scenarios that require rapid testing of a large number of coaxial cables. In the production line, operators can quickly complete the cable unlocking operation, improving the overall testing efficiency. Attached Figure Description

[0027] Example 1

[0028] like Figure 1-3 As shown, this utility model provides a technical solution: a coaxial cable testing microcapacitor contact positioning auxiliary fixture, including a coaxial cable 1, with connecting components arranged around the coaxial cable 1. The coaxial cable 1 is the test object, and the accurate testing of its performance depends on the reliable positioning and fixation of the auxiliary fixture.

[0029] The connecting component includes a ring test plate 2 and an auxiliary fixture body 3. One end of the ring test plate 2 is connected to the auxiliary fixture body 3 through a connecting mechanism. A test mechanism is provided inside the ring test plate 2 and the auxiliary fixture body 3.

[0030] The connecting mechanism includes a first slot 12 opened at the upper end of the auxiliary fixture body 3, a rectangular box 7 is provided on the outer wall of the auxiliary fixture body 3, a second slot 13 is provided inside the rectangular box 7, two trapezoidal screw rods 10 are rotatably connected between the left and right inner walls of the second slot 13, the two trapezoidal screw rods 10 in the second slot 13 are threadedly connected to a moving plate 9, the moving plate 9 is slidably connected to the inner walls on both sides of the second slot 13, and multiple connecting rods 11 are fixedly connected to one end of the moving plate 9 near the adjacent first slot 12.

[0031] The testing mechanism includes a limiting block 4 fixedly connected to the lower end of the annular test plate 2, and the limiting block 4 is provided with multiple limiting grooves 5.

[0032] Among them, the limiting block 4 is adapted to be connected with the first slot 12; the limiting groove 5 is provided in several groups from top to bottom, and each group of limiting groove 5 is matched with the connecting rod 11 through the docking depth of the limiting block 4.

[0033] By setting the limiting groove 5 and multiple trapezoidal lead screws 10, the ring test plate 2 and the auxiliary fixture body 3 can adapt to coaxial cables 1 of different sizes. The distance between the ring test plate 2 and the auxiliary fixture body 3 can be adjusted according to the actual situation of different cables. This operation method not only improves the convenience of testing, but also ensures that the fixing and release of cables can be completed quickly and stably during the testing of cables of different sizes.

[0034] Specifically, the cooperation between the limiting grooves 5 of different depths and the connecting rods 11 can accommodate coaxial cables 1 of different diameters. When the diameter of the coaxial cable 1 is large, the distance between the ring test plate 2 and the auxiliary fixture body 3 is reduced accordingly. At this time, the connecting rods 11 can be inserted into the limiting grooves 5 at the innermost position. Conversely, when the diameter of the coaxial cable 1 is small, the connecting rods 11 are inserted into the limiting grooves 5 at the outermost position, thereby achieving precise positioning and stable fixation.

[0035] Example 2

[0036] like Figure 1-3 As shown, the ring test plate 2 and the auxiliary fixture body 3 are rotatably connected at the other end. This rotatable connection allows the ring test plate 2 to rotate at a certain angle around the connection point. When placing and removing the coaxial cable 1, simply rotate the ring test plate 2 upwards to open it, and the coaxial cable 1 can be easily placed or removed.

[0037] One end of a trapezoidal lead screw 10 extends to the outside of a rectangular box 7 and is fixedly connected to a knob 6, which provides an interface for the operator to manually rotate the trapezoidal lead screw 10.

[0038] Both trapezoidal lead screws 10 in the second slot 13 are equipped with transmission wheels, and the transmission wheels are connected by a synchronous transmission belt 8. The synchronous transmission belt 8 can ensure that the two trapezoidal lead screws 10 rotate synchronously, so that the moving plate 9 moves smoothly and evenly under the drive of the two trapezoidal lead screws 10, avoiding problems such as jamming or tilting of the moving plate 9 caused by asynchronous rotation of the two trapezoidal lead screws 10.

[0039] The implementation principle of this utility model of a miniature capacitive contact positioning auxiliary fixture for coaxial cable testing is as follows: In use, the coaxial cable 1 to be tested is first placed between the ring test plate 2 and the auxiliary fixture body 3. Since the other end of the ring test plate 2 and the auxiliary fixture body 3 are rotatably connected, the ring test plate 2 can be rotated upwards at a certain angle to more easily place the coaxial cable 1. After placing the coaxial cable 1, the ring test plate 2 is rotated downwards so that the limiting block 4 of the ring test plate 2 is inserted into the first slot 12 of the auxiliary fixture body 3. Then, the knob 6 is turned. The rotation of knob 6 drives the connected trapezoidal lead screw 10 to rotate. Since the two trapezoidal lead screws 10 in the second slot 13 are connected by synchronous transmission belt 8, the rotation of knob 6 will drive multiple trapezoidal lead screws 10 to rotate synchronously. The rotation of trapezoidal lead screws 10 causes the moving plate 9 to move along the inner wall of the second slot 13, thereby driving multiple connecting rods 11 to move into the corresponding limiting slots 5, completing the stable connection between the annular test plate 2 and the auxiliary fixture body 3. At this time, the coaxial cable 1 is stably fixed in the auxiliary fixture, and the test can begin.

[0040] When disassembly is required, simply turn knob 6 to rotate trapezoidal screw 10 in the opposite direction, causing moving plate 9 and connecting rod 11 to move in the opposite direction. Connecting rod 11 exits from limiting groove 5, and the connection between annular test plate 2 and auxiliary fixture body 3 is released. At this time, annular test plate 2 can be rotated upward to open and the tested coaxial cable 1 can be taken out. This design greatly improves the efficiency of cable replacement and testing, and is especially suitable for scenarios that require rapid testing of a large number of coaxial cables. In the production line, operators can quickly complete the cable unlocking operation without spending a lot of time on complex disassembly and installation steps, reducing waiting time during testing, improving overall testing efficiency, and effectively meeting the needs of large-scale production.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
