Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a quick-plug power connector for safely isolating an external environment. Background Art

[0002] At present, the power connectors commonly used in the market mainly rely on the mechanical contact between the plug and the socket to complete power transmission. However, in actual use, since the contact surface between the plug and the socket is not completely sealed, and the use environment is complex and changeable, the gap between the plug and the socket can easily become a channel for dust, water stains and other impurities to enter. The design of the plug and the socket lacks an effective isolation mechanism, resulting in external contaminants entering the electrical contact area between the plug and the socket, which can easily cause short circuit failures, affect the stability of power transmission, and increase maintenance costs and downtime.

[0003] In addition, the existing plug-socket connection method usually relies only on the physical friction after the plug is inserted into the socket. This connection method is prone to failure after long-term use or in special environments. Once mechanical vibration or other external forces act, the plug may gradually loosen or even fall off the socket, causing the device to suddenly lose power, seriously affecting the normal operation of the device. A loose plug may also generate sparks, which not only threatens the personal safety of users, but may also cause fire accidents.

[0004] Therefore, the present invention provides a quick-plug power connector that is safely isolated from the external environment, which is particularly suitable for occasions that require frequent plugging and unplugging and have high safety requirements. Summary of the invention

[0005] In order to overcome the shortcomings of insufficient sealing and fastening of the plug and socket of the existing connector, the present invention provides a quick-plug power connector that can safely isolate the external environment.

[0006] A quick-plug power connector for safely isolating an external environment comprises a socket, the socket being plugged with a plug, the plug being horizontally slidably connected with a sliding cover for covering the connection port between the socket and the plug, a side of the plug close to the socket being fixedly connected with a limit block symmetrically distributed along the plug, the limit block being slidably connected to the sliding cover, the limit block being threadedly connected with a screw, the screw being rotatably connected to the sliding cover, a rotating block being rotatably connected to a side of the limit block away from the screw, the socket being provided with a limit channel symmetrically distributed along the socket, the limit channel being limitedly matched with the corresponding limit block, the rotating block being rotatably connected with a friction wheel, the friction wheel being frictionally matched with the socket, an extrusion plate being slidably connected inside the limit block, the extrusion plate being rotatably connected to an adjacent screw, and the extrusion plate being extrusion-matched with an adjacent rotating block on a side away from the screw.

[0007] In addition, it is particularly preferred that it further includes adjusting buttons symmetrically distributed along the sliding cover, and the adjusting buttons are fixedly connected to an end of the screw rod away from the limiting block.

[0008] In addition, it is particularly preferred that the limiting block is connected to the adjacent rotating block via a rotating shaft.

[0009] In addition, it is particularly preferred that a receiving cavity for hiding the wire is provided on a side of the plug close to the wire.

[0010] Furthermore, it is particularly preferred that a first wedge surface is provided on a side of the extrusion plate away from the screw, and a second wedge surface is provided on a side of the rotating block close to the adjacent extrusion plate, and the second wedge surface can move to contact the adjacent first wedge surface.

[0011] In addition, it is particularly preferred that a side of the socket close to the friction wheel is provided with third wedge surfaces symmetrically distributed along the socket, and the friction wheel can contact the adjacent third wedge surfaces when rotating.

[0012] In addition, it is particularly preferred that a sealing gasket is further included, and the sealing gasket is fixedly connected to a side of the sliding cover close to the socket.

[0013] In addition, it is particularly preferred that the sealing gasket is configured in a square shape.

[0014] In addition, it is particularly preferred that it also includes a limit ring symmetrically distributed along the sliding cover, the limit ring is spline-connected to the sliding cover, the limit ring is arranged in an I-shape, and the inner ring of the limit ring is provided with an annularly distributed slot, and the slot is used to lock the adjacent adjustment button.

[0015] In addition, it is particularly preferred that a sliding guide frame is also included, which is horizontally slidably connected to a side of the plug close to the accommodating cavity, and an arc-shaped spring piece is fixedly connected in the accommodating cavity. The wire is bent around one end of the arc-shaped spring piece, and the other end of the arc-shaped spring piece is fixedly connected to the sliding guide frame. The sliding guide frame is fixedly connected to strip spring pieces symmetrically distributed along the sliding guide frame, and the strip spring pieces are in contact with the adjacent limiting rings.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The present invention prevents dust, water stains and other substances from entering through the gap between the plug and the socket through the isolation and sealing effect of the sliding cover, reduces the occurrence of short circuit events, and improves the stability factor and safety factor of the interface connection between the plug and the socket.

[0018] The present invention can automatically achieve the effect of fastening the plug and the socket by means of the covering operation, so that the plug cannot be easily pulled out of the socket, thereby preventing the plug from accidentally falling off and causing the device to interrupt operation due to power failure. At the same time, it prevents the plug from generating sparks due to looseness during use, thereby reducing the risks of electric shock and fire. When the covering is released, the fastening effect of the plug and the socket is automatically released, which is convenient for quickly pulling out the plug.

[0019] After the plug is inserted into the socket and the cover is locked, the limiting ring is pulled outward so that the limiting ring clamps the adjusting button through the clamping groove, thereby achieving the effect of limiting the adjusting button and preventing the screw from loosening due to vibration during the operation of the equipment being transmitted to the screw, thereby preventing the covering effect and the fastening effect from being affected.

[0020] The present invention utilizes the deformed strip spring piece to reset and quickly toggle the limit ring to slide outwards and clamp the adjusting button. In this way, there is no need to manually pull the limit ring out of the sliding cover, and the operation is simple and convenient.

[0021] The present invention utilizes the strip spring piece to limit the limit ring, thereby preventing the limit ring from sliding into the sliding cover due to the vibration during the operation of the equipment being transmitted to the limit ring, thereby further preventing the sealing effect and the fastening effect from being affected.

[0022] When the wire is pulled by external force, the wire pulls the strip spring piece through the sliding guide frame, and the strip spring piece pushes the limit ring outward. In this way, the limit ring can always maintain the effect of locking the adjustment button during the use of the connector, and the stability is strong.

[0023] The arc-shaped spring piece of the present invention can not only provide a certain degree of buffering protection for the wire when the wire is pulled by external force, thereby preventing the stress from being concentrated on the connection end of the wire and the plug due to the external force, and thus avoiding the phenomenon of wire breakage, but can also pull the sliding guide frame to slide inward and reset when the external force disappears, thereby driving the wire to reset. Two practical functions are achieved through one mechanical part, reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0038] Embodiment 1: A quick-plug power connector for safely isolating the external environment, such as Figures 1 to 8As shown, a socket 101 is provided, a plug 102 is inserted into the socket 101, a sliding cover 103 is slidably connected to the plug 102 along the left and right directions for covering the connection port between the socket 101 and the plug 102, the sliding cover 103 is set as a hollow U-shaped cover, a limit block 104 symmetrically distributed along the front and back of the plug 102 is fixedly connected to the left side of the plug 102, the limit block 104 is slidably connected to the sliding cover 103, and a screw is threadedly connected to the right side of the limit block 104. The right part of the screw rod 105 is rotatably connected to the inner side of the right part of the slide cover 103, and the right end of the screw rod 105 is fixedly connected to an adjusting button 1051 symmetrically distributed along the front and back of the slide cover 103. The left side of the inner part of the limit block 104 is connected to the rotating block 106 through the rotating shaft 1052. The socket 101 is provided with a limit channel 107 symmetrically distributed along the front and back of the socket 101. The limit channel 107 is limited and matched with the corresponding limit block 104. The plug 102 is close to the wire. A receiving cavity 108 for hiding the wire is opened on one side. By inserting a part of the wire into the receiving cavity 108, the connection between the wire and the plug 102 can be buffered when subjected to external pulling force. The right part of the rotating block 106 is rotatably connected to the friction wheel 201, and the limiting block 104 is slidably connected to the extrusion plate 202 in the left and right directions. The extrusion plate 202 is rotatably connected to the left end of the adjacent screw 105. The side surface of the left part of the extrusion plate 202 is provided with a first wedge surface 203, and the side of the rotating block 106 close to the adjacent extrusion plate 202 is provided with a second wedge surface 204. The second wedge surface 204 moves to the left and can contact the adjacent first wedge surface 203. The socket 101 is provided with third wedge surfaces 205 symmetrically distributed along the socket 101. The friction wheel 201 rotates outward to contact the adjacent third wedge surface 205. The left side of the sliding cover 103 is fixedly connected to a sealing gasket 301, and the sealing gasket 301 is set in a mouth shape.

[0039] The socket 101 is pre-embedded and fixedly installed in a carrier (such as a wall) that needs to be connected to a power source. When the plug 102 is inserted into the socket 101, the limit block 104 is inserted into the limit channel 107. At this time, the limit block 104 and the friction wheel 201 are adjacent to the third wedge surface 205. In order to safely isolate the connected plug 102 and socket 101 from the external environment, the specific operation is as follows: turn the adjustment button 1051 so that the screw 105 drives the sliding cover 103 to slide toward the side close to the socket 101, and adjust it until the sliding cover 103 drives the sealing gasket 301 to seal and contact with the outer wall of the carrier, so that the connection between the plug 102 and the socket 101 can be sealed.

[0040] In the process that the screw 105 drives the sliding cover 103 to slide toward the side close to the socket 101, the screw 105 simultaneously drives the extrusion plate 202 to move toward the side close to the rotating block 106, so that the second wedge surface 204 approaches the first wedge surface 203, and then the extrusion plate 202 squeezes the second wedge surface 204 through the first wedge surface 203, and then the rotating block 106 drives the friction wheel 201 to rotate toward the side close to the third wedge surface 205 until the friction wheel 201 is tightly attached to the third wedge surface 205, so that the limit block 104 cannot be easily pulled out of the limit channel 107, and the plug 102 cannot be easily pulled out of the socket 101.

[0041] When it is necessary to unplug the plug 102, first turn the adjusting knob 1051 in the opposite direction, so that the screw 105 drives the sliding cover 103 to slide to the side away from the socket 101, and in the process of turning the adjusting knob 1051 in the opposite direction, the screw 105 simultaneously drives the extrusion plate 202 to move to the side away from the rotating block 106, so that the second wedge surface 204 is separated from the first wedge surface 203, and then the plug 102 can be unplugged. In the process of unplugging the plug 102, the plug 102 drives the limit block 104 to be pulled out of the limit channel 107, and the limit block 104 drives the rotating block 106 and the friction wheel 201 to be pulled out together, and under the squeezing effect of the third wedge surface 205, the friction wheel 201 drives the rotating block 106 to rotate in the opposite direction and reset.

[0042] In summary, the present invention prevents dust, water stains and other substances from entering through the gap between the plug 102 and the socket 101 through the isolation and sealing effect of the sliding cover 103, reduces the occurrence of short circuit events, and improves the stability and safety factor of the interface connection between the plug 102 and the socket 101.

[0043] Moreover, the present invention can automatically achieve the effect of fastening the plug 102 and the socket 101 by means of the covering operation, so that the plug 102 cannot be easily pulled out from the socket 101, thereby preventing the plug 102 from accidentally falling off, which would cause the device to interrupt operation due to power failure, and at the same time prevent the plug 102 from generating sparks due to looseness during use, thereby reducing the risk of electric shock and fire, and automatically releasing the fastening effect of the plug 102 and the socket 101 when the covering is removed, thereby facilitating the quick removal of the plug 102.

[0044] Embodiment 2: Based on embodiment 1, Fig. 9 and Fig.10As shown, it also includes a limit ring 401 symmetrically distributed along the sliding cover 103, the limit ring 401 is spline-connected to the sliding cover 103, and the limit ring 401 is arranged in an I-shape. The left side of the limit ring 401 is used to prevent the limit ring 401 from sliding excessively to the right, thereby preventing the limit ring 401 from sliding to the right from the sliding cover 103, and the right side of the limit ring 401 is used to prevent the limit ring 401 from sliding excessively to the left, thereby preventing the limit ring 401 from being completely embedded in the sliding cover 103 and unable to be pulled out. The adjusting button 1051 is located on the right side of the limit ring 401, and the inner circle of the limit ring 401 is provided with a plurality of annularly distributed card grooves 402. When the limit ring 401 is pulled out to the right, the card groove 402 can hold the adjacent adjusting button 1051 in place to prevent the adjusting button 1051 from rotating at will.

[0045] After the plug 102 is inserted into the socket 101 and the cover is locked, the limit ring 401 is pulled outward so that the limit ring 401 clamps the adjusting button 1051 through the card slot 402, thereby achieving the effect of limiting the adjusting button 1051 and preventing the screw 105 from loosening due to the vibration during the operation of the equipment being transmitted to the screw 105, thereby preventing the covering effect and the fastening effect from being affected. When it is necessary to unplug the plug 102, before twisting the adjusting button 1051 in the opposite direction, the limit ring 401 is first pushed into the sliding cover 103 to release the limit on the adjusting button 1051.

[0046] like Fig.11 and Fig.12 As shown, it also includes a sliding guide frame 501, which is slidably connected to one side of the plug 102 close to the receiving cavity 108 along the left and right directions. An arc-shaped spring piece 502 is fixedly connected in the receiving cavity 108. The wire is bent around one end of the arc-shaped spring piece 502, and the other end of the arc-shaped spring piece 502 is fixedly connected to the sliding guide frame 501. The left side of the sliding guide frame 501 is fixedly connected to a strip spring piece 503 symmetrically distributed along the front and back of the sliding guide frame 501, and the strip spring piece 503 is in contact with the adjacent limiting ring 401.

[0047] When the wire on the plug 102 passes through the arc-shaped spring piece 502, it bends and bypasses the arc-shaped spring piece 502, so that a part of the wire is reserved for pulling. When the wire on the plug 102 is accidentally pulled by external force, the bent part of the wire is straightened, and the arc-shaped spring piece 502 deforms adaptively, providing a certain degree of buffering protection for the wire, thereby preventing external force from pulling and causing stress to be concentrated on the connection end of the wire and the plug 102, thereby avoiding the phenomenon of wire breakage.

[0048] In addition, initially, the strip spring piece 503 contacts the inner side of the limiting ring 401. Since the limiting ring 401 will be driven to move to the left synchronously during the closing process of the sliding cover 103, before turning the adjusting button 1051 to close the cover, the strip spring piece 503 is manually pressed first to make the strip spring piece 503 bend toward the side away from the limiting ring 401 to prevent the strip spring piece 503 from blocking the limiting ring 401. After the closing process is completed, the strip spring piece 503 is released, and the strip spring piece 503 is reset to drive the limiting ring 401 to slide outward to clamp the adjusting button 1051. In this way, there is no need to manually and laboriously pull the limiting ring 401 out of the sliding cover 103, and the operation is simple. For convenience, at this time, the strip spring piece 503 also limits the limit ring 401, preventing the vibration during the operation of the equipment from being transmitted to the limit ring 401, causing the limit ring 401 to slide into the sliding cover 103, thereby further preventing the sealing effect and the fastening effect from being affected. Moreover, even if the limit ring 401 slides slightly into the sliding cover 103, when the wire is pulled by external force, the wire can pull the strip spring piece 503 through the sliding guide frame 501, and the strip spring piece 503 pushes the limit ring 401 outward. In short, during the use of the connector, the limit ring 401 can maintain the effect of locking the adjustment button 1051, and the stability is strong.

[0049] In addition, the arc-shaped spring piece 502 of the present invention can not only provide a certain degree of buffering protection for the wire when the wire is pulled by external force, but also pull the sliding guide frame 501 to slide inward and reset when the external force disappears, thereby driving the wire to reset. Two practical functions are achieved through one mechanical part, reducing costs.

[0050] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
