A rotary plug for easy extraction

Abstract

This invention provides a rotary plug for easy removal, comprising a housing and a conductive component fixed to the lower end of the housing. The conductive component has multiple conductive tabs for electrical connection with an external power strip. An ejection mechanism is mounted on the housing, which lifts the housing to separate the conductive tabs from the power strip. The ejection mechanism includes a support member slidably mounted vertically within the housing and a power cord housing hinged to the upper end of the housing. The power cord housing is drivenly connected to the support member. When the plug is removed, rotating the power cord housing causes the support member to extend from the housing and press against the power strip, thereby separating the conductive tabs from the power strip. This rotary plug overcomes the shortcomings of existing plugs, such as inconvenient removal and low socket utilization due to the inability to rotate.

Description

Technical Field

[0001] This invention relates to the field of plugs, and in particular to a rotary plug that is easy to unplug. Background Technology

[0002] A plug is a component used to connect to a socket to supply power to an appliance. The basic structure of a plug includes a plug housing and prongs (also called pins) connected to the housing. In use, the prongs are inserted into the socket holes and connect with the socket sleeve to draw power. To ensure a reliable connection between the prongs and sleeve, the sleeve is designed to hold the prongs with considerable clamping force. To prevent damage to the socket when unplugging, one hand needs to hold the socket while the other hand grasps the plug, making it inconvenient, especially when the plug is inserted into a power strip, requiring both hands to remove it. Furthermore, most power strips on the market are multi-socket sockets. While they appear to have many holes, existing plugs are fixed in one direction when inserted, and because they cannot rotate, they cannot be effectively used with household multi-socket sockets, resulting in relatively low utilization. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] The problem to be solved by the present invention is to provide a rotating plug that is easy to unplug, so as to overcome the shortcomings of existing plugs that are inconvenient to unplug and have low socket utilization due to their inability to rotate.

[0005] (II) Technical Solution

[0006] To address the aforementioned technical problem, this invention provides a rotary plug for easy removal, comprising a housing and a conductive component fixed to the lower end of the housing. The conductive component has multiple conductive tabs for electrical connection with an external power strip. A push-out mechanism is mounted on the housing, which lifts the housing to separate the conductive tabs from the power strip. The push-out mechanism includes a support member slidably mounted vertically within the housing and a power cord shell hinged to the upper end of the housing. The power cord shell is drivenly connected to the support member. When the plug is removed, rotating the power cord shell causes it to drive the support member to extend from the housing and press against the power strip, thereby separating the conductive tabs from the power strip. This plug allows for easy removal by simply holding the plug with one hand and pulling the power cord upwards, providing safety, effectiveness, and freeing up the other hand, making it simple and convenient.

[0007] Furthermore, the housing includes a lower housing and an upper housing rotatably mounted on the lower housing. The power cord housing is hinged to the upper housing, and the support member is slidably mounted inside the lower housing. The outer wall of the lower housing is provided with a slot, and the inner wall of the upper housing is provided with a retaining ring that engages with the slot. The slot has an arc-shaped limiting groove facing one side, and the retaining ring has a limiting block facing one side that can slide within the arc-shaped limiting groove.

[0008] Furthermore, the power cord housing includes a cover housed inside the upper housing and a cable guide tube extending toward one side of the cover house. The cable guide tube is hinged to the outer wall of the upper housing. The lower end of the cover house is symmetrically provided with lugs, and the lugs abut against the upper end face of the support member.

[0009] Furthermore, the ejection mechanism also includes multiple springs, which abut against the support member and the lower housing, and the springs always cause the support member to tend to move into the lower housing. A first spring seat is provided on the support member, and a second spring seat that mates with the first spring seat is provided on the lower housing, with the spring installed between the first spring seat and the second spring seat.

[0010] Furthermore, the support member includes an annular body located within the lower housing, at least one set of top columns symmetrically arranged at the lower end of the annular body, a guide groove provided on the outer wall of the top column, and a guide block provided on the inner wall of the lower housing that cooperates with the guide groove.

[0011] Furthermore, the socket also includes a wire clamping assembly slidably mounted on the upper side of the conductive component. The wire clamping assembly includes a wire clamping block and a wire clamping seat, with the two sides of the wire clamping block and the wire clamping seat respectively connected by screws. A connecting piece is symmetrically arranged on the lower side of the wire clamping seat, and a protruding post is provided on the connecting piece. A U-shaped seat is provided on the upper side of the conductive component, and the protruding post is placed inside the U-shaped seat.

[0012] Furthermore, the conductive component includes an insulating base fixedly connected to the lower housing, three conductive plates are mounted on the insulating base, and a pressure plate is fixed to the upper end of the insulating base.

[0013] (III) Beneficial Effects

[0014] The present invention provides a rotary plug that is easy to unplug, which has the following advantages compared with the prior art:

[0015] 1) It is equipped with an ejection mechanism. Through the cooperation of the support and the power cord shell, when the plug is unplugged, the power cord shell is rotated. The power cord shell drives the support to extend out of the shell and abut against the socket, thereby separating the conductive plate from the socket. The plug can be easily unplugged by holding the plug with one hand and pulling the power cord upward. It is safe, effective and frees up the other hand, which is simple and convenient.

[0016] 2) The upper and lower housings are rotatably connected, and the power cord housing is hinged to the upper housing. By pulling the power cord, the upper housing can be rotated, thereby adjusting the orientation of the power cord, preventing the power cord from blocking the socket hole, and improving the utilization rate of the socket.

[0027] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0028] See Figures 1 to 9 The present invention provides a rotary plug that is easy to unplug, including a housing 1 and a conductive component 2 fixed to the lower end of the housing 1. The conductive component 2 has a plurality of conductive pieces 21 for electrical connection with an external power strip.

[0029] See Figure 1 , Figure 4 and Figure 5 The housing 1 includes a lower housing 11 and an upper housing 12 rotatably mounted on the lower housing 11. The outer wall of the lower housing 11 is provided with a slot 111, and the inner wall of the upper housing 12 is provided with a retaining ring 121 that engages with the slot 111. The engagement of the slot 111 and the retaining ring 121 ensures that the upper housing 12 can rotate relative to the lower housing 11. The slot 111 has an arc-shaped limiting groove 112 facing one side, and the retaining ring 121 has a limiting block 122 facing one side that can slide within the arc-shaped limiting groove 112. The engagement of the arc-shaped limiting groove 112 and the limiting block 122 restricts the rotation angle of the upper housing 12. In this embodiment, the upper housing 12 can rotate 180 degrees, that is, rotate 90 degrees to each side.

[0030] See Figures 1 to 3 An ejection mechanism is installed on the housing 1. The ejection mechanism is used to lift the housing 1 to separate the conductive sheet 21 from the conductive clip of the power strip. The ejection mechanism includes a support member 31 that is vertically slidably installed inside the housing 1 and a power cord housing 32 that is hinged to the upper end of the housing 1. The power cord housing 32 is drivenly connected to the support member 31. The power cord housing 32 is hinged to the upper housing 12, and the support member 31 is slidably installed inside the lower housing 11.

[0031] See Figure 4 and Figure 6The power cord housing 32 includes a cover 321 housed within the upper housing 12 and a conduit 322 extending toward one side of the cover 321. The conduit 322 is used for the external power cord 5 to pass through. After passing through, the power cord 5 passes through the wire clamping assembly 4 and is electrically connected to the conductive assembly 2. The conduit 322 is hinged to the outer wall of the upper housing 12. Lugs 323 are symmetrically arranged at the lower end of the cover 321. The lugs 323, the cover 321, and the conduit 322 are an integral structure. The lugs 323 abut against the upper end face of the support member 31. When pulled out, the power cord 5 is pulled upward to rotate the conduit 322, thereby pressing down the lugs 323 of the cover 321. The pressing down of the lugs 323 drives the support member 31 to slide downward.

[0032] See Figure 3 and Figure 4 The ejection mechanism also includes multiple springs 33. In this embodiment, there are two springs 33 arranged symmetrically. The springs 33 abut against the support member 31 and the lower housing 11. The springs 33 always cause the support member 31 to tend to move into the lower housing 11. Under normal conditions, the support member 31 is retracted into the lower housing 11 under the action of the springs 33. A first spring seat 314 is provided on the support member 31, and a second spring seat 113 that cooperates with the first spring seat 314 is provided on the lower housing 11. The spring 33 is installed between the first spring seat 314 and the second spring seat 113. The spring seat limits the spring, which facilitates installation and prevents the spring from shifting.

[0033] See Figure 3 and Figure 7 The support member 31 includes an annular body 311 located within the lower housing 11. At least one set of top pillars 312 are symmetrically arranged at the lower end of the annular body 311. The outer wall of the top pillars 312 is provided with a guide groove 313, and the inner wall of the lower housing 11 is provided with a guide block 114 that cooperates with the guide groove 313. In this embodiment, in order to ensure the lifting effect, there are two sets of top pillars 312, i.e., four pillars, with two pillars on each side. A first spring seat 314 is provided between two adjacent top pillars 312 to ensure uniform force distribution and structural stability. The cooperation between the guide block 114 and the guide groove 313 can guide the support member 31, preventing it from being misaligned and stuck during sliding, thus ensuring reliability. The annular body 311 and the top pillars 312 are an integral structure.

[0034] See Figure 8 and Figure 9The plug also includes a wire clamping assembly 4 slidably mounted on the upper side of the conductive component 2. The wire clamping assembly 4 includes a wire clamping block 41 and a wire clamping seat 42. The two sides of the wire clamping block 41 and the wire clamping seat 42 are connected by screws. In use, the screws are turned to bring the wire clamping block 41 and the wire clamping seat 42 closer together, thereby clamping the power cord between the wire clamping block 41 and the wire clamping seat 42 and preventing the power cord from detaching from the plug. A connecting piece 421 is symmetrically arranged on the lower side of the wire clamping seat 421, and a protrusion 422 is provided on the connecting piece 421. A U-shaped seat 231 is provided on the upper side of the conductive component 2, and the protrusion 422 is placed in the U-shaped seat 231. This structure ensures that the wire clamping assembly 4 can slide and rotate relative to the conductive component 2, so that when the plug is unplugged, the wire clamping assembly 4 can adjust with the power cord, preventing the power cord from being pulled and ensuring the connection is firm.

[0035] See Figure 8 and Figure 9 The conductive component 2 includes an insulating base 22 fixedly connected to the lower housing 11. The insulating base 22 has grooves on both sides to facilitate the extension of the top post 312. Three conductive plates 21 are mounted on the insulating base 22, corresponding to the live wire, neutral wire, and ground wire of the power cord, respectively. In actual use, two conductive plates 21 can also be used, corresponding to the live wire and neutral wire, respectively. A pressure plate 23 is fixed to the upper end of the insulating base 22. The pressure plate 23 has through holes for the wires in the power cord to pass through. A fixing plate is provided at the upper end of the conductive plate 21, through which each wire is electrically connected to its corresponding conductive plate.

[0036] When the plug is unplugged, the power cord can be pulled upwards (or the power cord housing 32 can be rotated directly). The power cord housing 32 rotates, and the lugs of the power cord housing 32 press down on the support member 31. The top post 312 of the support member 31 extends out from the lower housing 11 and abuts against the power strip, thereby lifting the plug and separating the conductive piece 21 from the conductive clip of the power strip.

[0037] This embodiment provides a rotary plug for easy removal, which is equipped with an ejection mechanism. Through the cooperation of a support member and a power cord shell, when the plug is removed, the power cord shell is rotated, and the power cord shell drives the support member to extend out of the shell and abut against the socket, thereby separating the conductive plate from the socket. The plug can be easily removed by holding the plug with one hand and pulling the power cord upwards, which is safe, effective, and frees up the other hand, making it simple and convenient. The upper and lower shells are rotatably connected, and the power cord shell is hinged to the upper shell. By pulling the power cord, the upper shell can be rotated, thereby adjusting the orientation of the power cord and preventing the power cord from blocking the socket hole, thus improving the utilization rate of the socket. This overcomes the defects of existing plugs that are inconvenient to remove and have low socket utilization due to the inability to rotate.

[0038] The above description is only a preferred embodiment of the present invention. 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 invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
