Description

Technical Field

[0001] This utility model belongs to the field of plug testing technology, specifically relating to a positioning and insertion fixture for plug testing. Background Technology

[0002] Plug testing refers to the process of inspecting and testing a power plug, which typically involves inserting the plug into the socket of the testing component. Since the socket's pin positions are fixed, the plug's prongs need to be aligned with the pins during insertion to ensure proper positioning.

[0003] Existing positioning and plugging fixtures for plug detection typically use a groove with the same shape as the plug's outer side to limit the plug's position during use. For example, a rectangular groove limits a rectangular plug, so that the plug's pins automatically align with the socket after being placed in the groove. However, the outer side of a three-prong plug is generally circular. When a three-prong plug is placed in an arc-shaped groove, the three-prong plug and the groove can still rotate relative to each other. This can easily result in the three-prong plug's pins being misaligned, making it difficult to align the pins with the socket and compromising the ease of positioning. Utility Model Content

[0004] The purpose of this invention is to provide a positioning and insertion fixture for plug detection. It can push the long plug pins upward to the upper center position after the clamp plate rotates, so that the plug pins are aligned with the socket holes and the pins are in a straight position. After straightening, the clamping block clamps and fixes the plug, so that the plug pins are kept in the straight position, thereby improving the convenience of positioning.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A positioning and insertion fixture for plug detection includes a base plate with a groove formed thereon, and further includes:

[0007] A limiting mechanism is provided on a base plate. The limiting mechanism includes two sliders provided on one side of a groove. The two sliders are arranged opposite to each other. The sliders are slidably mounted to the base plate. A clamping plate is rotatably mounted on the slider.

[0008] A clamping mechanism is disposed on a substrate and includes a plurality of clamping blocks disposed on the outside of a groove, the clamping blocks being slidably mounted to the substrate.

[0009] The clamping plate rotates upwards, pushing the long prongs of the plug to rotate upwards and center them. The clamping block moves to the side closer to the groove and clamps the plug so that the position of the long prongs remains fixed.

[0010] A rotating shaft is fixedly connected to the side of the clamping plate near the slider. The rotating shaft is rotatably connected to the slider. A motor is fixedly connected to the slider. A transmission belt is connected between the output end of the motor and the rotating shaft.

[0011] The clamping plate has a sloping surface at one end near the inner side.

[0012] A first telescopic rod is provided on the outside of the slider, the output end of the first telescopic rod is fixedly connected to the slider, and the first telescopic rod is fixedly connected to the substrate.

[0013] The clamping block is slidably connected to the substrate. A second telescopic rod is provided at the end of the clamping block away from the groove. The output end of the second telescopic rod is fixedly connected to the clamping block, and the second telescopic rod is fixedly connected to the substrate.

[0014] The substrate has a sliding groove, which slides in conjunction with the clamping block.

[0015] The technical effects achieved by this utility model are as follows:

[0016] The clamping plate of this invention rotates and pushes the long plug to rotate upward to the upper center position, so that the plug's plug is aligned with the socket's hole and the plug is in a straight position. This makes it easy to rotate the plug's plug back to a straight position even if the plug's plug deviates to the sides during the process of inserting the plug into the groove. After straightening, the clamping block clamps and fixes the plug, keeping the plug's plug in a straight position, thereby improving the convenience of positioning. Attached Figure Description

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1 to 7 As shown, a positioning and insertion tooling for plug detection includes a base plate 10 with a groove 11. It also includes: a limiting mechanism 20 disposed on the base plate 10, comprising two sliders 21 disposed on one side of the groove 11, the two sliders 21 being opposite to each other and slidably mounted to the base plate 10, with a clamping plate 22 rotatably mounted on each slider 21; and a clamping mechanism 30 disposed on the base plate 10, comprising a plurality of clamping blocks 31 disposed outside the groove 11, the clamping blocks 31 being slidably mounted to the base plate 10.

[0028] It should be noted that the plug adapted to this utility model is a three-prong plug, which is existing technology. The three prongs of the three-prong plug are one long prong and two short prongs. The long prong is the ground prong. The length of the long prong is longer than the length of the short prongs to ensure electrical safety. When the plug is inserted into the socket, the long prong is connected first, and when the plug is removed from the socket, the long prong is disconnected last. A detection component is provided on the side of the limiting mechanism 20 away from the groove 11. The detection component includes a socket that is slidably mounted on the base plate 10. The socket is provided with three holes corresponding to the three prongs. The detection component is existing technology and will not be described in detail here. The hole on the socket corresponding to the long prong is located in the upper center position. When the long prong of the plug is in the upper center position, the prong of the plug is aligned with the hole of the socket and the prong is in a straight position. When the long prong of the plug is not in the upper center position, the prong of the plug is not aligned with the hole of the socket and the prong is in a misaligned position.

[0029] It should also be noted that the bottom of the groove 11 is arc-shaped, and the groove 11 rotates with the outer side of the plug. The rotation center axis of the clamp 22 is not collinear with the axis of the groove 11. When both clamps 22 are rotated to the top, the distance between the two clamps 22 is equal to the thickness of the long plug. The inner side of the clamp 31 is arc-shaped, and the inner side of the clamp 31 fits against the outer side of the plug. The distance between the clamp 22 and the groove 11 is less than the length of the long plug and greater than the length of the short plug. There are two clamps 31, which are located on both sides of the groove 11. In the initial state, both clamps 22 are rotated to the bottom.

[0030] In this embodiment, the plug is inserted into the groove 11 from top to bottom. If the plug prongs are not aligned, the long prongs may be biased to either side. The two clamping plates 22 rotate upward from both sides. After one clamping plate 22 contacts the long prong, it pushes the long prong to rotate upward, so that the long prong rotates to the upper center position. At this time, the clamping plates 22 on both sides of the long prong limit the long prong, so that the long prong is kept in the upper center position. At this time, the clamping block 31 moves along the substrate 10 towards the side closer to the groove 11, so that the clamping block 31 limits and fixes the plug, so that the plug pins are kept in the correct position. After the slider 21 moves outward, it drives the clamp 22 away from the long plug pins, so that the limiting mechanism 20 no longer blocks the plug and socket. This makes it easier for the socket to slide along the base plate 10 and approach the plug, so that the plug can be inserted into the socket. Compared with the prior art, no matter how much the plug pins are deflected to both sides and placed in the groove 11, the clamp 22 can be used to straighten the plug pins, so that the plug pins and the socket holes are aligned, improving the convenience of positioning.

[0031] In this case, since the length of the long prong of the plug is longer than that of the short prong, the clamp 22 will not come into contact with the short prong of the plug during the upward rotation. At the same time, the clamp 22 pushes the long prong to rotate, and the long prong also drives the plug to rotate in the groove 11.

[0032] like Figure 3 As shown, a rotating shaft 41 is fixedly connected to the side of the clamping plate 22 near the slider 21. The rotating shaft 41 is rotatably connected to the slider 21. A motor 42 is fixedly connected to the slider 21. A transmission belt 43 is connected between the output end of the motor 42 and the rotating shaft 41.

[0033] It should be noted that the output end of the motor 42 is fixedly connected to the first transmission wheel, and the shaft 41 is fixedly connected to the second transmission wheel. The transmission belt 43 is wound around the first transmission wheel and the second transmission wheel. A tensioning wheel (not shown in the figure) is provided on one side of the transmission belt 43. The tensioning wheel is existing technology and is used to maintain the appropriate tension of the transmission belt 43. It will not be described in detail here.

[0034] In this embodiment, after the motor 42 is working, the output end rotates and drives the rotating shaft 41 to rotate along the slider 21 through the transmission belt 43. The slider 21 drives the clamping plate 22 to rotate. When the clamping plate 22 rotates upward, it is convenient to push the long plug to rotate upward to the upright state. When the clamping plate 22 rotates downward, it is convenient to reset the clamping plate 22.

[0035] like Figure 3 , Figure 5 and Figure 6 As shown, the clamping plate 22 has an inclined surface 221 at one end near the inner side.

[0036] It should be noted that the inclined surface 221 is tilted outwards, and in the initial state, the ends of the inclined surfaces 221 of the two clamping plates 22 are in contact with each other.

[0037] In this embodiment, during the process of inserting the plug into the groove 11, if the long prong is located at the lower end of the plug, the long prong will first come into contact with the inclined surface 221 during the downward movement. Since the inclined surface 221 is inclined outward, the long prong slides outward along one of the inclined surfaces 221, so that the long prong and the plug rotate together. This avoids the clamp 22 from obstructing the downward movement of the long prong when it is initially located at the bottom, thereby avoiding the obstruction of the clamp 22 during the process of inserting the plug into the groove 11, and making it easier to insert the plug into the groove 11 from top to bottom.

[0038] like Figure 2 and Figure 4 As shown, a first telescopic rod 44 is provided on the outer side of the slider 21. The output end of the first telescopic rod 44 is fixedly connected to the slider 21, and the first telescopic rod 44 is fixedly connected to the substrate 10.

[0039] It should be noted that the first telescopic rod 44 is preferably a pneumatic telescopic rod in this utility model, and the bottom of the slider 21 is slidably engaged with the base plate 10.

[0040] In this embodiment, after the first telescopic rod 44 is working, the output end drives the slider 21 to slide along the substrate 10, making the sliding process of the slider 21 along the substrate 10 more stable.

[0041] like Figure 2 and Figure 4 As shown, the clamping block 31 is slidably connected to the substrate 10. A second telescopic rod 45 is provided at the end of the clamping block 31 away from the groove 11. The output end of the second telescopic rod 45 is fixedly connected to the clamping block 31, and the second telescopic rod 45 is fixedly connected to the substrate 10.

[0042] It should be noted that the second telescopic rod 45 is preferably a pneumatic telescopic rod in this utility model, and the bottom of the clamping block 31 is slidably engaged with the base plate 10.

[0043] In this embodiment, after the second telescopic rod 45 is in operation, the output end drives the clamping block 31 to slide along the substrate 10, making the process of the clamping block 31 sliding along the substrate 10 more stable.

[0044] like Figure 2 and Figure 4 As shown, a sliding groove 12 is provided on the substrate 10, and the sliding groove 12 is slidably engaged with the clamping block 31.

[0045] In this embodiment, the slide groove 12 cooperates with the clamping block 31 to prevent the clamping block 31 from rotating in the slide groove 12, making the process of the clamping block 31 sliding along the substrate 10 more stable.

[0046] The working principle of this utility model is as follows: After the plug is placed in the groove 11, the clamping plate 22 rotates upward. If the plug prongs are already in the correct position, the two clamping plates 22 respectively fit against the two sides of the long prongs to limit the long prongs. If the plug prongs are not in the correct position, the clamping plate 22 contacts the long prongs that are biased to one side and pushes the long prongs to rotate upward to the upper center position, so that the two clamping plates 22 respectively fit against the two sides of the long prongs to limit the long prongs, thereby making the plug prongs in the correct position. At this time, the clamping block 31 slides along the base plate 10 and clamps and fixes the plug, so that the plug prongs are kept in the correct position, thereby improving the convenience of positioning.

[0047] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
