[0002] The coaxial line of the drone gimbal is generally connected to the adapter board socket using a double-terminal buckle method. According to the number of coaxial line cores, the gimbal is divided into 36-core, 50-core, 128-core and other specifications. After the drone gimbal is processed, the coaxial line and the socket need to be separated and performance tested. At present, during the gimbal test, the coaxial line and the socket are mainly separated by manually picking up the terminal. Since the force of manual operation is difficult to control, the coaxial line terminal is easy to be damaged, and the coaxial line is easy to be pulled off, resulting in poor socket conductivity, high scrap rate of coaxial line terminals and sockets, and many abnormal problems in the gimbal function test, which leads to a high misdetection rate of the gimbal function test. In addition, in the above operation method, the exposed length of the left and right ends of the coaxial line is less than 0.2mm, which makes it difficult to achieve synchronous and balanced separation of the two sockets. The separation and testing efficiency of the coaxial line terminals and sockets is low, which makes the production efficiency of the gimbal insufficient. Utility Model Content

[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0020] Please combine Figure 1-4 The utility model discloses a device 10 for non-destructively pulling out multi-coaxial line terminals, which can reduce the scrap rate of coaxial line terminals and sockets and improve separation and production efficiency. The device includes a pressure plate seat 100 fixed on an adapter plate 20, a rotating shaft 200 hingedly connected to the upper surface of the pressure plate seat 100, a handle 300 fixedly connected to one side of the rotating shaft 200 and capable of driving the rotating shaft 200 to rotate relative to the pressure plate seat 100, and a spring 400 fixed on a side of the handle 300 adjacent to the pressure plate seat 100 and providing a restoring force for the handle 300 to be pressed down. The pressure plate seat 100 is fixed to the adapter plate 20 by bolts, and the adapter plate 20 is an adapter test plate of the pan / tilt head. At least three protruding teeth 500 are arranged at intervals on the rotating shaft 200 at the part facing away from the handle 300. The at least three protruding teeth 500 separate the area between the two ends of the rotating shaft 200 to form at least two fixed positions. A socket 30 is fixed in each fixed position. The upper surface of the socket 30 is provided with a buckle position for buckling the coaxial terminal 40. The end of the coaxial terminal 40 protrudes from the buckle position and is suspended above the corresponding protruding teeth 500. The protruding teeth 500 are lifted up and push the coaxial terminal 40 away from the socket 30 when the handle 300 is pressed down. It should be noted that the length of the protruding teeth 500 is greater than the distance between the upper surface of the socket 30 and the lower surface of the rotating shaft 200. In this way, the protruding teeth 500 can not only be lifted up to push the coaxial terminal 40 when the handle 300 is pressed down, but also the protruding teeth 500 can limit the amplitude of the lifting of the handle 300 to prevent the spring 400 from being overstretched and failing.
[0021] The above-mentioned device 10 for non-destructively pulling out multiple coaxial terminal pins, the socket 30 is fixed on the pressure plate seat 100 and is located beside the rotating shaft 200, which not only facilitates the snap-fit connection between the socket 30 and the coaxial terminal 40, but also when the pan / tilt function test is required, only the handle 300 needs to be pressed, and the convex teeth 500 on the rotating shaft 200 are lifted and push the coaxial terminal 40 upward, so that the coaxial terminal 40 is separated from the socket 30, thereby realizing the separation of the coaxial terminal 40 from the socket 30, and avoiding the damage caused by manually pulling the coaxial terminal 40. The problems of terminal breakage and coaxial line being pulled off can effectively ensure the conductivity of the socket 30 and reduce the scrap rate of the coaxial line terminal 40 and the socket 30; and compared with the method of manually pulling the coaxial line terminals 40 one by one, the device only needs to press the handle 300 to separate multiple coaxial line terminals 40 from the socket 30 at one time, which reduces the difficulty of separating the coaxial line terminals 40 from the socket 30 and improves the separation efficiency of the coaxial line terminals 40 and the socket 30 as well as the pan-tilt function test efficiency and production efficiency.
[0022] In one embodiment, two lugs 110 are disposed opposite to each other on the pressure plate seat 100, and a rotation zone is formed between the two lugs 110. A plug hole is provided on the lug 110, and the plug hole passes through two opposite side walls of the lug 110, that is, the plug hole passes through one side of the lug 110 adjacent to the rotation zone and one side of the lug 110 facing away from the rotation zone. The rotating shaft 200 is located in the rotation zone and the plug holes of the lugs 110 on both sides are correspondingly penetrated. The annular side surface of the rotating shaft 200 is provided with a convex plate 210 extending along the length direction of the rotating shaft 200, and each convex tooth 500 is fixed on the side of the convex plate 210 facing away from the rotating shaft 200. The handle 300 faces away from the convex plate 210 and is fixedly connected to the middle part of the annular side surface of the rotating shaft 200. Preferably, the rotating shaft 200, the convex plate 210, the convex tooth 500 and the handle 300 are integrally formed to reduce the processing difficulty of the device. The end of the rotating shaft 200 is sleeved with a collar 220, which abuts against a side of the lug 110 that faces away from the rotating area. Further, the collar 220 is fixed to the end of the rotating shaft 200 to limit the position of the rotating shaft 200 and prevent the rotating shaft 200 from shaking on the lug 110.
[0023] In this embodiment, the area below the rotating shaft 200 on the pressing plate seat 100 is recessed to form a limiting area 120 for setting the socket 30. The limiting area 120 runs through a side of the pressing plate seat 100 away from the end of the handle 300, and the socket 30 is fixed in the limiting area 120. In this way, the setting height of the socket 30 is reduced, and the height of the buckle position on the socket 30 is further reduced. In this way, when the coaxial terminal 40 is buckled on the buckle position of the socket 30, the end of the coaxial terminal 40 extending out of the buckle position abuts against the upper surface of the convex tooth 500, or the gap between the end of the coaxial terminal 40 and the convex tooth 500 is small. When the pan / tilt function is tested, only the handle 300 needs to be gently pressed, and the convex tooth 500 is lifted slightly to push the coaxial terminal 40 away from the socket 30, thereby reducing the difficulty of separating the coaxial terminal 40 from the socket 30. Further, the rotation angle of the handle 300 relative to the pressing plate seat 100 is less than 30°. Preferably, the rotation angle of the handle 300 relative to the pressure plate seat 100 is between 10-30°, ensuring that the coaxial terminal 40 is separated from the socket 30, and multiple sockets 30 can be easily separated from the coaxial terminal 40 by single pressure, thereby improving the separation efficiency. In addition, in this embodiment, the gap between the convex tooth 500 and the side of the socket 30 is less than 0.05mm, so that the length of the coaxial terminal 40 required to protrude from the buckle position is small. In other words, when the coaxial terminal 40 protrudes from the buckle position by a certain length, the effective area between the convex tooth 500 and the coaxial terminal 40 is increased, and the terminal damage caused by the excessive force of the convex tooth 500 on the coaxial terminal 40 is reduced.
[0024] In one embodiment, three convex teeth 500 are arranged at intervals on the convex plate 210 to separate the rotation area to form two fixed positions. That is to say, two sockets 30 are arranged side by side and at intervals in the limiting area 120, and a coaxial terminal 40 is correspondingly buckled on each socket 30. In this way, by pressing the handle 300 once, the separation of the double-terminal double sockets 30 can be achieved, and the separation efficiency of the coaxial terminal 40 and the socket 30 is improved. In other embodiments, according to the test and design requirements of the pan / tilt, three or more sockets 30 can be arranged in the limiting area 120 at the same time to further improve the working efficiency, which will not be repeated here. It should be noted that in this embodiment, when the handle 300 is pressed down, the two ends of the coaxial terminal 40 are pushed by the convex teeth 500 on both sides at the same time, and the two ends of the coaxial terminal 40 are evenly stressed, so that the balanced separation of the coaxial terminal 40 is achieved, so that the pin spring of the coaxial terminal 40 is twisted within a small elastic range without damaging the terminal pin and the socket 30. The two coaxial terminals 40 use the same rotating shaft 200. Only by pressing the handle 300, the two ends of the two coaxial terminals 40 can be balanced and separated from the socket 30, so that the coaxial terminals 40 can be pulled out of the socket 30 without damage, reducing the high scrap rate of the coaxial line and the adapter plate 20 and improving production efficiency.
[0025] A first groove 310 is provided on the lower surface of the handle 300, and a second groove 130 is provided on the pressure plate seat 100 below the handle 300. One end of the spring 400 is embedded in the first groove 310 and abuts against the groove bottom surface of the first groove 310, and the other end of the spring 400 is embedded in the second groove 130 and abuts against the groove bottom surface of the second groove 130. By providing the first groove 310 and the second groove 130, the spring 400 can be prevented from being deformed and displaced during the pressing process of the handle 300. When the spring 400 is installed, only the two ends of the spring 400 need to be respectively embedded in the first groove 310 and the second groove 130, and the spring 400 can be limited by the inner walls of the first groove 310 and the second groove 130. In one embodiment, the two ends of the spring 400 are fixedly connected to the groove bottom surfaces of the first groove 310 and the second groove 130 through hooks, so as to further improve the stability of the installation of the spring 400 and prevent the spring 400 from escaping from the first groove 310 and the second groove 130. In another embodiment, a limiting boss 320 is provided on the lower surface of the handle 300 away from the rotating shaft 200. The limiting boss 320 is located at the notch of the first groove 310. By providing the limiting boss 320, the spring 400 can be limited to prevent the spring 400 from falling out of the first groove 310 and then injuring people or objects. In addition, by providing the limiting boss 320, when the handle is fully pressed down, the limiting boss 320 abuts against the pressure plate seat, which can reduce the impact on the pressure plate seat caused by the lower surface of the handle being fully pressed on the pressure plate seat.
[0026] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0027] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
