Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to a plug-in structure and an indicator light. Background Technology

[0002] In the field of electrical connections, plug-in structures are a common type of electrical connection widely used in various electronic devices, electrical products, and power systems. They enable rapid connection and disconnection between power sources and loads, facilitating the normal operation and maintenance of equipment. With the continuous development of technology and the increasing demands for the safety and convenience of electrical equipment, higher requirements are being placed on the performance and functionality of plug-in structures.

[0003] Traditional plug-in structures mostly use direct plugging and unplugging to achieve electrical connection. In some special scenarios, such as vibration or external impact, the plug and slot are prone to loosening or detachment, resulting in unstable circuit connection or even disconnection, affecting the normal operation of the equipment. At the same time, in the power-off state, the plug-in components are easily affected by external factors and accidentally connect to the power supply, posing a safety hazard. In addition, the lack of intuitive power supply status indication makes it impossible for users to quickly determine whether the plug is in place or whether the power is on, affecting the convenience and safety of use. Therefore, we propose a plug-in structure and indicator light to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies, such as the traditional plug-in structure being prone to loosening and detachment, leading to unstable circuit connections; the easy accidental power connection during power failure, posing a safety hazard; and the lack of power supply status indication. Therefore, a plug-in structure and indicator light are proposed.

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

[0006] A plug-in structure and indicator light, including a mounting base and a socket;

[0007] The inner wall of the mounting base is rotatably connected to a rotating block. Three slots are opened in the groove at the top of the rotating block. Three inserts corresponding to the slots are fixedly connected to the bottom of the socket. The three inserts are inserted into the corresponding slots.

[0008] A terminal is fixedly installed in the slot. The terminal contacts the insert and extends through the rotating block to its outside. Three power supply boards corresponding to the terminals are fixedly connected to the inner wall of the mounting base.

[0009] The rotating block is provided with a limiting component, including a slider that is slidably connected in the sliding cavity of the rotating block, a limiting rod that abuts against the inclined surface of the slider, and a first spring sleeved on the limiting rod;

[0010] The socket is equipped with a fixing component, including fixing ears symmetrically arranged on the outer wall of the socket and elastically pressing balls inside the positioning cylinder. The balls are embedded in the positioning holes on the inner wall of the mounting base to achieve fixation.

[0011] In one possible design, the limiting component further includes a pressing rod slidably disposed in the second sliding hole of the rotating block, the bottom end of the pressing rod being fixedly connected to the top of the slider, and the top end extending into the groove; a second spring is sleeved on the outer wall of the pressing rod, and its two ends respectively abut against the second limiting ring and the inner wall of the second sliding hole.

[0012] In one possible design, the inclined surface of the slider abuts against one end of the limiting rod, and the other end of the limiting rod is inserted into the insertion hole in the inner wall of the mounting base by the inclined surface of the slider.

[0013] In one possible design, the positioning cylinder of the fixing component is provided with a third spring, the two ends of which respectively abut against the inner wall of the positioning cylinder and the ball bearing.

[0014] In one possible design, the top of the rotating block has two positioning slots corresponding to the fixing ears, and the fixing ears are fitted into the positioning slots.

[0015] In one possible design, the top of the mounting base has a clearance groove corresponding to the ball bearing.

[0016] In one possible design, conduits are fixedly connected to the outer walls of the mounting base and the socket, respectively. The power supply wire passes through the conduit in the mounting base and is electrically connected to the power supply board, while the output wire passes through the conduit in the socket and is electrically connected to the plug.

[0017] In one possible design, the mounting base has multiple mounting holes.

[0018] An indicator light includes a plug-in structure as described in any of the above technical solutions, wherein an indicator light is fixedly disposed on the top of the socket, and the indicator light is electrically connected to three plug prongs.

[0019] In this application, firstly, in the initial state, the terminals of the rotating block are disconnected from the power supply board of the mounting base, and the power is disconnected. At this time, the limiting rod is inserted into the insertion hole on the inner wall of the mounting base under the action of the first spring to fix the rotating block and prevent it from rotating, ensuring that the plug-in structure is in a safe locked state when not in use, and avoiding accidental power connection.

[0020] When the socket is inserted, the three prongs at the bottom of the socket are aligned with the three slots at the top of the rotating block and inserted. The bottom of the socket will press the pressing rod, which moves downward and causes the slider to move downward. The inclined surface of the slider disengages from the contact with one end of the limiting rod. The limiting rod retracts into the first sliding hole under the action of the first spring. The other end of the limiting rod disengages from the socket, releasing the fixing of the rotating block and allowing the rotating block to rotate, preparing for subsequent rotation to connect the power.

[0021] Next, rotate the rotating block so that the terminals on the rotating block contact the power supply board on the mounting base to connect the power. During the rotation, the ball bearings on the fixing ears on the outer wall of the socket slide along the inner wall of the mounting base. When the rotation reaches the appropriate position, the ball bearings are embedded in the positioning holes on the inner wall of the mounting base to fix the socket and prevent it from falling off. At the same time, the positioning groove on the top of the rotating block engages with the fixing ears to further fix the rotating block and ensure the stability of the connection.

[0022] The indicator light on the top of the socket is electrically connected to the three plug prongs. When the power is on, the indicator light lights up, intuitively showing the power on / off status and providing users with a clear power status indication for convenient operation and management.

[0023] When the power needs to be disconnected, rotate the rotating block in the opposite direction to disengage the terminal from the power supply board, thus disconnecting the power. When the socket is unplugged, the pressing rod moves upward under the action of the second spring, thereby moving the slider. The inclined surface of the slider abuts against one end of the limit rod, inserting the other end of the limit rod into the socket to fix the rotating block and prevent it from rotating to connect the power.

[0024] Beneficial effects: In this utility model, the plug-in structure and indicator light realize the rotational on / off control of the power supply through the rotational connection between the rotating block and the mounting base. The operation is simple and safe and reliable. At the same time, the setting of the limit component can fix the rotating block in the power off state, preventing it from accidentally rotating and connecting the power supply, further improving the safety of operation.

[0025] In this utility model, the plug-in structure and indicator light are fixed by a fixing component. After the socket is connected to the power supply by rotating the rotating block, the socket is fixed, ensuring the stability of the electrical connection under the power-on state and reducing the problem of poor contact caused by loose socket. The positioning groove on the top of the rotating block and the fixing ear on the outer wall of the socket are locked together, so that the rotating block is fixed at the same time as the socket, further enhancing the stability of the connection.

[0026] In this utility model, the plug-in structure and indicator light are integrated on the top of the socket. The indicator light automatically lights up when the plug-in structure is powered on, intuitively displaying the power supply status. Users can quickly judge whether the plug-in is in place and the circuit is conductive through the indicator light, avoiding equipment damage or electric shock risk caused by poor contact.

[0027] In this invention, the power supply is switched on and off by rotating the rotating block and the mounting base. The operation is simple and safe. The limiting component can fix the rotating block when the power is off to prevent accidental connection. The fixing component reduces the looseness of the socket and poor contact. The positioning groove and fixing ear clip enhance the connection stability. The indicator light on the top of the socket lights up when the power is on, which intuitively shows the power supply status and helps users quickly judge the plugging and conduction status, reducing the risk of equipment damage and electric shock.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] Example 1: Refer to Figure 1-6A plug-in structure includes a mounting base 1, a rotating block 2, and a socket 3. The inner wall of the mounting base 1 is rotatably connected to the rotating block 2. A groove is formed on the top of the rotating block 2, and three slots 7 are provided in the groove. Terminals 8 are fixed in the slots 7, and one end of the terminal 8 extends through the rotating block 2 to the outside. Three power supply plates 5 are fixed to the inner wall of the mounting base 1 for contacting the terminals 8 to supply power. The bottom of the socket 3 has three inserts 9 corresponding to the slots 7. After the inserts 9 are inserted into the slots 7, they contact the terminals 8 to achieve circuit conduction. At the same time, connecting conduits 6 are fixed to the outer walls of both the mounting base 1 and the socket 3. The conduits 6 on the mounting base 1 contain power supply wires that are electrically connected to the power supply plates 5, and the conduits 6 on the socket 3 contain output wires that are electrically connected to the inserts 9 for power transmission. The mounting base 1 also has multiple mounting holes 20 to facilitate fixing the mounting base 1 in the required position.

[0037] The limiting assembly includes components such as a slider 10, a limiting rod 11, and a pressing rod 13. The rotating block 2 has an internal sliding cavity, within which the slider 10 is located, with one side having an inclined surface, allowing it to slide within the cavity. The outer wall of the rotating block 2 has a first sliding hole communicating with the sliding cavity. The limiting rod 11 slides within the first sliding hole, with one end extending into the sliding cavity and contacting the inclined surface of the slider 10. A first limiting ring is fitted onto the outer wall, slidingly engaging with the inner wall of the first sliding hole. Simultaneously, a first spring 12 is fitted, with both ends contacting one side of the first limiting ring and one side of the inner wall of the first sliding hole, respectively. In the initial state, the limiting rod 11, under the pressure of the inclined surface of the slider 10, inserts into a hole in the inner wall of the mounting base 1, fixing the rotating block 2 and preventing its rotation.

[0038] The top of the rotating block 2 has a second sliding hole communicating with the sliding cavity. The pressing rod 13 is slidably disposed in the second sliding hole, with its top end extending into the groove and its bottom end fixedly connected to the top of the slider 10. A second spring 14 and a second limiting ring are sleeved on the outer wall of the pressing rod 13. The second limiting ring slides in cooperation with the inner wall of the second sliding hole, and the two ends of the second spring 14 respectively abut against the bottom of the second limiting ring and the inner wall of the bottom of the second sliding hole. When the socket 3 is inserted, its bottom presses against the pressing rod 13, causing the slider 10 to move downward, so that the inclined surface of the slider 10 disengages from the contact with one end of the limiting rod 11. Under the action of the first spring 12, the limiting rod 11 retracts into the first sliding hole, releasing the fixation on the rotating block 2.

[0039] The fixing assembly consists of two fixing ears, a positioning cylinder, a ball bearing 16, and a third spring 15. The two fixing ears are symmetrically fixed to the outer wall of the socket 3. A positioning cylinder is fixedly embedded on the side of each fixing ear furthest from the socket 3. A ball bearing 16 is located at the opening of the positioning cylinder, and a third spring 15 is located inside. The two ends of the third spring 15 respectively abut against one side of the inner wall of the positioning cylinder and the ball bearing 16. A positioning hole 17 corresponding to the ball bearing 16 is opened on the inner wall of the mounting base 1. When the socket 3 is powered on by rotating the rotating block 2, the ball bearing 16 is embedded into the positioning hole 17 under the action of the third spring 15, thus fixing the position of the socket 3.

[0040] This application can be used in the field of electrical connection technology, or in other fields applicable to this application.

[0041] Example 2: Reference Figure 3-6 Based on Embodiment 1, an improvement is made: a plug-in structure and indicator light, which are applied to the field of electrical connection technology. In addition, the top of the rotating block 2 has two positioning grooves 18 corresponding to the fixing ears, and the fixing ears can be engaged with the positioning grooves 18 to further fix the rotating block 2 and the socket 3. The top of the mounting base 1 has a relief groove 19 corresponding to the ball 16, which positions the fixing ears when the socket 3 is inserted.

[0042] Indicator light 4 is fixedly mounted on the top of socket 3 and electrically connected to three plugs 9. When the power is turned on, that is, when plugs 9, terminals 8, and power supply board 5 form a conductive circuit, indicator light 4 lights up, visually indicating the power on / off status.
