Description

Technical Field

[0001] This utility model relates to the field of socket technology, specifically a safety socket with a socket sleeve. Background Technology

[0002] As the most basic electrical connection component, power sockets are widely used in various fields of production and life. A typical socket usually includes a socket body, an internal conductive sleeve, and a socket for plugging in. Such sockets are simple in structure, low in cost, and reliable in operation, meeting basic power supply needs.

[0003] However, with the increasing number of electrical devices and the continuous expansion of application scenarios, users' expectations for socket functions have gone beyond basic power supply needs, turning to a more intelligent and user-friendly interactive experience. Traditional socket designs have room for improvement in terms of status visualization. When a plug is inserted, the socket itself often lacks a clear physical indicator. This not only makes it difficult for users to quickly identify which socket is powered from a distance, causing inconvenience for daily power management, but more importantly, it cannot effectively warn of a common and dangerous situation: that is, the plug is not fully inserted, resulting in poor contact, a loose connection, and a risky state where the plug is still live. This not only brings some inconvenience to power management, but also creates potential safety management hazards in certain scenarios.

[0004] Therefore, since it does not meet the existing needs, we propose a safety socket with a socket sleeve. Summary of the Invention

[0005] This invention provides a safety socket with a plug sleeve. The solution utilizes a linkage mechanism consisting of a plug sleeve slider, a square shaft, gears, and a rack to convert the linear motion of the plug into slider rotation, reliably triggering a microswitch to externally indicate the plugging status. The initial position also provides dust protection, and the unique synchronous triggering mechanism ensures that both prongs must be inserted simultaneously for operation. This enhances both visibility of the status and improves safety and reliability, solving the problems mentioned in the background section.

[0006] This utility model provides the following technical solution: a safety socket with a plug sleeve, including a socket body, the socket body having a double-hole socket, the socket body having a connecting electrode inside, the side wall of the socket body having a plurality of storage cavities, each storage cavity having a first sliding groove on its side wall, and the inner wall of the first sliding groove having a movable rack.

[0007] Each of the storage cavities is provided with a set of insert assembly, which includes a square shaft, an insert slider fixedly sleeved on the square shaft, and a rotating gear fixedly mounted on the square shaft.

[0008] The two ends of the square shaft are slidably engaged with the first groove via ball bearing sliders.

[0009] As an optional solution for a safety socket with a plug sleeve according to the present invention, the inner wall of the first sliding groove is also symmetrically provided with a second sliding groove, one of which is provided with a connecting spring and a support block, and the support block is in contact with a square shaft.

[0010] As an optional solution for a safety socket with a plug sleeve according to the present invention, the plug sleeve slider is provided with a trigger protrusion, and the inner wall of the storage cavity is provided with a micro switch. The trigger protrusion can squeeze the micro switch when the plug sleeve slider rotates.

[0011] As an alternative solution to the safety socket with a plug-in according to the present invention, the plug-in assembly further includes a connecting torsion spring, which is sleeved on a square shaft.

[0012] As an optional solution for a safety socket with a plug sleeve according to the present invention, a set of the plug sleeve assembly includes two plug sleeve sliders, and a connecting sleeve is provided between the two plug sleeve sliders.

[0013] As an optional solution for the safety socket with a plug sleeve according to this utility model, the connecting sleeve has two sliding connecting rods slidably arranged inside, and a return spring is provided between the sliding connecting rods and the connecting sleeve.

[0014] As an optional solution for a safety socket with a plug sleeve according to the present invention, one end of the sliding link is slidably disposed inside a limiting movement groove opened on the plug sleeve slider.

[0015] This utility model has the following beneficial effects:

[0016] 1. This safety socket with a plug sleeve utilizes a linkage mechanism inside the socket, consisting of a plug sleeve slider, a square shaft, gears, and a rack. This mechanism converts the linear insertion and removal motion of the plug into the rotational motion of the slider. This design reliably triggers a micro switch, providing a clear external indication of the plug's connection status. This effectively solves the problem of traditional sockets not being able to visually display the power-on status. Furthermore, the slider in its initial position also has a dustproof function. Its unique synchronous triggering mechanism ensures that triggering is only possible when both prongs are inserted simultaneously, further enhancing safety and reliability.

[0017] 2. This safety socket with a plug sleeve effectively counteracts the restoring force of the connecting spring by using the lateral clamping force formed by the rotating plug sleeve slider and the plug pin. This ensures that the component remains stably in the trigger position when powered on, completely avoiding accidental power outages caused by vibration or spring force, and greatly improving connection reliability. When the plug is unplugged, this constraint is automatically released. Under the coordinated action of the gear rack mechanism and the connecting torsion spring, the component can accurately and smoothly complete the automatic reset, simultaneously retracting the status indicator and restoring the dustproof function, achieving a balance between stable self-locking and fully automatic reset.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1, please refer to Figures 1-7 In order to add a status indication function that is linked to the plugging and unplugging action to the conventional socket, this solution specially installs a socket assembly 2 inside the socket body 1. The socket assembly 2 consists of a socket slider 201, a square shaft 202, a rotating gear 203 and a connecting torsion spring 204. The socket body 1 is provided with several sets of double-hole sockets 101 for inserting plugs, and the socket body 1 is also provided with a connecting electrode 102 that finally contacts the plug. The socket body 1 has a storage cavity 105 on its side wall. The storage cavity 105 has a first slide groove 103 on its side wall for the square shaft 202 to slide and limit. To ensure that the square shaft can rise and fall smoothly and transmit torque, ball sliders are installed at both ends. The ball sliders cooperate with the inner wall of the first slide groove 103 to effectively reduce the friction of movement. The inner wall of the first slide groove 103 has symmetrical second slide grooves 106. One of the second slide grooves 106 has a connecting spring 206 and a support block 205 inside. The support block 205 contacts the square shaft 202, so that the entire socket assembly 2 is lifted upward in the initial state.

[0030] The plug slider 201 in the plug assembly 2 is located below the double-port socket 101, and the upper surface of the plug slider 201 is initially attached to the bottom surface of the double-port socket 101 to prevent dust. The plug slider 201 is fixedly sleeved on the square shaft 202 to ensure the synchronicity of their rotational movement. A set of plug assemblies 2 includes two plug sliders 201, and a connecting sleeve 207 is provided between the plug sliders 201. Two sliding connecting rods 208 are slidably arranged inside the connecting sleeve 207. A return spring 210 is provided between the sliding connecting rods 208 and the connecting sleeve 207, and the other end of the sliding connecting rod 208 is slidably arranged inside the limiting movement groove 209 opened in the plug slider 201. This structure ensures that the entire plug assembly 2 can be smoothly pushed down only when the two pins of the double-port socket 101 are inserted at the same time and pressure is applied, thus forming a synchronous trigger authentication mechanism.

[0031] A movable rack 104 is also provided inside the first slide groove 103. The movable rack 104 is located in the lower middle part of the first slide groove 103. A rotating gear 203 is fixedly provided on the square shaft 202. When the user inserts the plug into the double-port socket 101, the plug pushes the plug sleeve slider 201 to move down. The square shaft 202 then moves down smoothly by means of the ball slider and pushes the support block 205 to compress the connecting spring 206. It should be noted that in the initial stage of this downward movement, although the rotating gear 203 is close to the movable rack 104, the ball sliders at both ends of the square shaft 202 are tightly constrained by the inner wall of the first slide groove 103. Their movement is strictly limited to vertical sliding and cannot rotate freely. Therefore, the plug insertion force will not directly cause the component to reverse, but is used entirely to overcome the elastic force of the connecting spring 206 to ensure that the component first makes the necessary vertical displacement.

[0032] Only when the square shaft 202 descends to the position where the rotating gear 203 and the moving rack 104 are fully engaged, is the vertical downward path mechanically blocked by the rack. Due to the constraint between the square shaft and the slider, the only way to continue downward is for the gear to roll along the rack. This process forces the square shaft 202 to rotate, causing the fixed insert slider 201 to rotate as well. The key to this embodiment is that the rotational movement of the insert slider 201 is used to trigger an additional function. Specifically, a trigger protrusion is provided on one of the insert sliders 201. When the slider rotates... The triggering protrusion can press a micro switch 107 fixed on the inner wall of the storage cavity 105, changing its state. It should be noted that the micro switch 107 is located on the side of the socket body 1, and the micro switch 107 can be an elastic block. A spring (not shown in the figure) is provided between the micro switch 107 and the socket body 1. That is to say, when the micro switch 107 is squeezed by the plug slider 201, the micro switch 107 will extend out of the socket body 1 to serve as a state indication signal for the completion of plugging and unplugging, realizing the external state indication function linked to the plugging and unplugging action.

[0033] Example 2 aims to effectively improve the stability of the socket assembly 2. This example is an improvement based on Example 1. For details, please refer to [link / reference]. Figures 1-7As the plug continues to be inserted, its metal contacts eventually make contact with the connecting electrode 102, energizing the plug. While the plug is fully inserted and connected, the socket assembly 2 remains stable in the triggered position (i.e., the state after downward movement and rotation) without rebounding under the restoring force of the connecting spring 206. The principle is that when the socket slider 201 rotates, its structure changes its contact relationship with the plug pins. The pins exert a lateral clamping or restraining force on the rotated slider. This force, combined with the upward force of the connecting spring 206, forms a new mechanical balance, effectively locking the vertical movement of the assembly and constituting a reliable "pin self-locking" mechanism. This self-locking mechanism ensures the plug remains stable in the connected state; reset only occurs after the pins are removed and the constraint is released.

[0034] When the user unplugs the plug, the pin pressure applied to the plug slider 201 disappears. At this time, the compressed connecting spring 206 begins to release its stored elastic potential energy, pushing the support block 205 upward. The support block 205 then transmits the force to the square shaft 202. The ball bearing sliders at both ends of the square shaft 202 slide smoothly upward along the inner wall of the first groove 103, causing the entire plug assembly 2 to begin to move upward. In the initial stage of the upward movement of the plug assembly 2, the rotating gear 203 fixed on the square shaft 202 then re-engages with the moving rack 104 fixed in the first groove 103. Due to the constraint of the rack, this upward linear motion is forced to be converted into the rotational motion of the gear, thereby driving the square shaft 202 to rotate in the opposite direction to that during insertion.

[0035] This reverse rotation is transmitted to the socket slider 201 fixedly sleeved on the square shaft 202, causing them to rotate synchronously. With the assistance of the reset torque applied by the connecting torsion spring 204, this rotation is completed quickly and accurately. As the socket slider 201 rotates, the trigger protrusion on it also disengages from the micro switch 107. The micro switch 107 automatically retracts under the action of its internal spring and resets into the socket body 1. The external indicator signal disappears. At the same time, under the continuous lifting action of the connecting spring 206, the socket assembly 2 finally returns to its initial highest position. At this time, the rotating gear 203 disengages from the moving rack 104, and the upper surface of the socket slider 201 re-fits tightly against the bottom of the double-hole socket 101, restoring its dustproof function. The entire device is now fully reset and in a standby state, waiting for the next plug insertion, realizing a complete automatic reset cycle.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
