Description

Technical Field

[0001] This utility model relates to the field of power supply testing device technology, specifically to a quick-plug connection structure with multiple power interfaces. Background Technology

[0002] The power interface is the interface between electronic devices and the power source. It is used to transmit power signals and provide power support. Power interface testing is essential during the manufacturing process or routine maintenance of electronic devices. It is an important process to ensure the performance and safety of the power interface of electronic devices.

[0003] Chinese utility model patent CN219226666U discloses a multi-interface power supply module, which includes "a main body, wherein a power supply module, a power socket, and a PCB circuit board are fixedly mounted on the main body, the power supply module is provided with multiple power interfaces, the power interfaces are connected to the terminals of the power socket and electrically connected to the PCB circuit board, and the power supply module is plugged into and fixed to the power socket"; however, in actual use, when testing the power interface plugging, after the interface and connecting wire are plugged in and installed, the connector and plug need to be frequently plugged in and unplugged. In order to ensure stable connection, the interface and plug are plugged in tightly, and force is required to pull out the wire, which can easily damage the connection between the interface and the device, causing poor contact problems, and thus lacking practicality. Utility Model Content

[0004] The purpose of this invention is to provide a quick-plug connection structure with multiple power interfaces to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-plug connection structure with multiple power interfaces, including a mounting base plate, a sleeve fixedly connected to the top surface of the mounting base plate, a limit component slidably connected inside the sleeve, and a telescopic component movably connected inside the limit component; The outer walls on both sides of the sleeve are provided with L-shaped grooves arranged in a circumferential array. The limiting component includes a limiting inner ring and a limiting outer ring, which are fixedly connected by limiting blocks on both sides; the telescopic component includes a connecting ring plate, and a plurality of telescopic rods are fixedly connected to the bottom surface of the connecting ring plate, and a compression spring is sleeved on the outer wall of each telescopic rod. The telescopic rod includes a top rod, a first slide cylinder, and a second slide cylinder. The outer wall of the top rod is slidably connected to the inner wall of the first slide cylinder, and the outer wall of the first slide cylinder is slidably connected to the outer wall of the second slide cylinder.

[0006] The beneficial effects of this utility model are as follows: This device, by setting a sleeve, a limiting component, and a telescopic component, allows the plug to be inserted into the through hole in the middle of the inner limiting ring. The side wall of the plug contacts the top surface of the inner limiting ring, and the inner limiting ring is pressed into the sleeve at the same time. The inner limiting ring moves together with the outer limiting ring through the limiting block, and at the same time, it compresses the spring. The limiting block slides in the groove. When the plug is inserted into the interface, the limiting block is locked through the L-shaped groove by rotating the outer limiting ring, thereby limiting and fixing the inner and outer limiting rings. When it is necessary to remove the plug, the locking of the limiting block is released by reversing the outer limiting ring, releasing the potential energy of the compression spring, thereby assisting in removing the plug. This achieves the effect of convenient and labor-saving insertion and removal, and further protects the connection between the device and the socket.

[0007] To achieve the effect of allowing the inner limiting ring to slide within the sleeve: The setting is further configured such that the limiting inner ring is located inside the sleeve, and the outer wall of the limiting inner ring is slidably connected to the inner wall of the sleeve.

[0008] By adopting the above technical solution, when the plug is inserted into the sleeve, the limiting inner ring can slide inside the sleeve without affecting the sleeve.

[0009] To enable the limiting outer ring to slide on the outer wall of the sleeve: The setting is further configured such that the limiting outer ring is located on the outside of the sleeve, and the inner wall of the limiting outer ring is slidably connected to the outer wall of the sleeve.

[0010] By adopting the above technical solution, when the plug is inserted into the sleeve, the limiting outer ring can slide on the outer wall of the sleeve without affecting the sleeve.

[0011] To enable the limiting block to slide within the L-shaped groove on the side wall of the sleeve: A further configuration is made whereby the outer walls of the limiting blocks on both sides are slidably connected to the inner walls of the L-shaped sliding grooves on both sides. By adopting the above technical solution, when the plug is inserted into the sleeve, the limiting blocks on both sides can slide within the L-shaped sliding grooves on both sides of the sleeve without affecting the sleeve.

[0012] To ensure the inner ring of the limiting device rotates smoothly within the sleeve: The connection is further configured such that the top surface of the connecting ring piece is in movable contact with the upper surface inside the limiting inner ring.

[0013] By adopting the above technical solution, the top surface of the connecting ring piece is in contact with the upper surface inside the limiting inner ring, thus not affecting the rotation of the limiting inner ring in the sleeve.

[0014] To ensure the compression rods can be placed stably: The telescopic rod is further configured such that its bottom surface is fixedly connected to the top surface of the mounting base plate.

[0015] By adopting the above technical solution, the compression rod can be placed stably when the connecting ring plate compresses the telescopic rod.

[0016] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. This description is merely illustrative and explanatory, and should not be construed as limiting the scope of protection of the present invention. Please refer to... Figures 1 to 6 A quick-plug connection structure with multiple power interfaces includes a mounting base plate 1, a sleeve 2 fixedly connected to the top surface of the mounting base plate 1, a limit component 3 slidably connected inside the sleeve 2, and a telescopic component 4 movably connected inside the limit component 3. L-shaped grooves 21 are distributed in a circular array on the outer walls of both sides of the sleeve 2; The limiting component 3 includes a limiting inner ring 31 and a limiting outer ring 32, and the limiting inner ring 31 and the limiting outer ring 32 are fixedly connected by limiting blocks 33 on both sides. The telescopic assembly 4 includes a connecting ring 41, and a plurality of telescopic rods 42 are fixedly connected to the bottom surface of the connecting ring 41. Each telescopic rod 42 is fitted with a compression spring 43 on its outer wall. The telescopic rod 42 includes a top rod 421, a first slide cylinder 422, and a second slide cylinder 423. The outer wall of the top rod 421 is slidably connected to the inner wall of the first slide cylinder 422, and the outer wall of the first slide cylinder 422 is slidably connected to the outer wall of the second slide cylinder 423.

[0019] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the limiting inner ring 31 is located inside the sleeve 2, and the outer wall of the limiting inner ring 31 is slidably connected to the inner wall of the sleeve 2.

[0020] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the limiting outer ring 32 is located on the outside of the sleeve 2, and the inner wall of the limiting outer ring 32 is slidably connected to the outer wall of the sleeve 2.

[0021] In this embodiment, as Figure 3 and Figure 4 As shown, the outer walls of the two limiting blocks 33 are slidably connected to the inner walls of the L-shaped grooves 21 on both sides.

[0022] In this embodiment, as Figure 4 and Figure 5 As shown, the top surface of the connecting ring 41 is in contact with the upper surface inside the limiting inner ring 31.

[0023] In this embodiment, as Figure 2 and Figure 6 As shown, the bottom surface of the telescopic rod 42 is fixedly connected to the top surface of the mounting base plate 1.

[0024] The quick-plug connection structure with multiple power interfaces operates as follows: First, the device is securely installed at the electrical equipment interface using the mounting base plate 1. When in use, the external plug is inserted into the through hole in the middle of the inner limiting ring 31. The side wall of the plug contacts the top surface of the inner limiting ring 31. During the insertion process, the inner limiting ring 31 moves into the sleeve 2 and presses in the connecting ring piece 41. The outer limiting ring 32 is also moved synchronously through the limiting block 33. This action causes the telescopic component 4 to retract: the top rod 421 is pressed into the slide cylinder 422, the slide cylinder 422 is pressed into the slide cylinder 423, realizing the compact folding of the telescopic rod 42. At the same time, the compression spring 43 is compressed and stored energy, and the limiting block 33 slides along the L-shaped slide groove 21. When the plug is fully inserted into the interface, the limiting outer ring 32 is rotated to make the limiting block 33 lock into the transverse groove of the L-shaped slide groove 21, realizing the limiting and fixing. When the plug is pulled out, the outer limiting ring 32 is rotated in the opposite direction to release the limit, the compressed spring 43 releases potential energy, and the auxiliary plug is easily pulled out.
