Description

Technical Field

[0001] The invention relates to the technical field of power plugs, in particular to a power plug power connection device. Background Art

[0002] The power plug, also known as a plug or a power converter, is a common electrical accessory in our daily life. Its main function is to connect electrical equipment to the power supply in order to provide the equipment with the required power. The design and structure of the power plug are usually determined according to the electrical standards and safety regulations of the country or region.

[0003] At present, when connecting the power connector, the two wires inside the wire are generally inserted into the power connection slot inside the plug, and then the wires are fixed in the power connection slot by tightening the screws. This power connection method requires the staff to use external tools to tighten the screws, which wastes time and reduces the power connection efficiency. At the same time, when the wire is subjected to external tension, the wires and the screws are prone to looseness, affecting the normal use of the plug. Summary of the invention

[0007] Preferably: the power connection mechanism includes a push rod penetrating the side wall of the plug, one end of the push rod is located inside the power connection slot, and a push plate is fixed to the other end of the push rod, and the push plate is connected to the outer wall of the plug through a first elastic member, wherein a protrusion capable of squeezing the push plate is fixed to the outside of the pressure plate.

[0008] Preferably: the pressing mechanism includes a limit frame arranged inside the power connection shell, a groove body is provided inside the limit frame, and a buffer assembly is connected to the end of the limit frame away from the pressure plate. When the pressure block completes the pressing of the wire, under the action of the buffer assembly, one end of the limit frame presses the pressure plate, thereby limiting the rotation of the pressure plate, and the other end of the limit frame presses the cable on the surface of the pressure block, thereby bending the cable.

[0009] Preferably: the buffer assembly includes a baffle fixedly connected to the inner wall of the power connection shell, a sliding rod passes through the inside of the baffle, one end of the sliding rod is fixedly connected to the limit frame, a second elastic member is provided outside the sliding rod, and both ends of the second elastic member are respectively fixedly connected to the limit frame and the baffle.

[0010] Preferably: the inflation mechanism includes an inflatable airbag fixedly connected to the inner wall of the power connection shell and symmetrically distributed, the inflatable airbag is connected to an air pipe, the other end of the air pipe passes through the limiting cylinder and is connected to the buffer airbag, and an extrusion component is provided inside the power connection shell. When the pressing block presses the wire against the surface of the support block, the extrusion component is used to squeeze the inflatable airbag.

[0011] Preferably: the extrusion assembly includes a pressure rod that passes through the support block and is symmetrically distributed, a movable plate is fixed to one end of the pressure rod away from the support block, one side of the movable plate is abuttingly connected to the inflatable airbag, and the other side of the movable plate is connected to the support block through a third elastic member.

[0013] Compared with the prior art, the invention has the following beneficial effects: when the plug is connected to electricity, the wire inside the cable is inserted into the electricity connection slot, and then the pressing plate is rotated. While the pressing plate is rotating, the convex block squeezes the abutment plate, and the abutment plate presses the wire tightly inside the electricity connection slot through the abutment rod, so that the purpose of electricity connection can be achieved without the aid of external tools, thereby improving the efficiency of electricity connection, and while the pressing plate is rotating, the cable inside the wire can be pressed and held on the surface of the support block through the pressing block, thereby fixing the cable and effectively improving the tensile strength of the wire;

[0014] When the pressing block presses the cable on the surface of the support block, the pressing plate and the pressing block are limited by the limiting frame, and one end of the limiting frame is tightly fitted with the side wall of the pressing plate, thereby limiting the pressing plate, thereby limiting the rotation of the pressing plate, and ensuring the pressing effect of the pressing block on the cable. The other end of the limiting frame can press the cable on the surface of the pressing block, and the limiting frame can press the cable on the surface of the pressing block while bending the cable, effectively improving the stability of the cable and further improving the tensile strength of the wire.

[0015] When the pressing block presses the cable on the surface of the supporting block, it will also squeeze the pressing rod. The pressing rod drives the moving plate to move, thereby squeezing the inflatable airbag, so that the gas inside the inflatable airbag enters the buffer airbag through the air pipe. When the pressing block presses the cable on the surface of the supporting block, the buffer airbag is fully expanded and fits tightly with the wire. On the one hand, it improves the sealing performance between the wire and the guide cylinder, thereby preventing moisture or dust in the air from entering the power connection shell. On the other hand, it can play a buffering role for the wire, thereby reducing the wear between the wire and the guide cylinder, and effectively improving the service life of the wire.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0023] In one embodiment, see Figure 1 and Figure 2The power plug connection device comprises a connection shell 1, wherein a guide cylinder 7 is passed through one side wall of the connection shell 1, and two symmetrically distributed plugs 5 are passed through the side wall of the connection shell 1 opposite to the guide cylinder 7, and the plugs 5 and the guide cylinder 7 are fixedly connected to the side wall of the connection shell 1, wherein the plugs 5 are provided with a connection groove 6 on one end surface inside the connection shell 1, and a connection mechanism 2 is provided inside the connection groove 6, and the connection mechanism 2 is used for connecting the wire and the plug 5, and the connection shell 1 is provided with symmetrically distributed pressure plates 11 and symmetrically distributed support plates 11. The support block 9 is fixedly connected to the inner wall of the power connection shell 1, and the pressure plate 11 is rotatably connected to the inner wall of the power connection shell 1 through a rotating rod 12. A pressure block 10 is fixed to the side of the pressure plate 11 close to the support block 9. The power connection shell 1 is provided with a symmetrically distributed pressing mechanism 3, and the pressing mechanism 3 is used to press the pressing plate 11 so that the pressing plate 11 presses the wire on the surface of the support block 9. The guide cylinder 7 is provided with a buffer airbag 8, and the buffer airbag 8 is connected to an inflation mechanism 4, and the inflation mechanism 4 is used to inflate the buffer airbag 8.

[0024] In this embodiment, when the power plug is connecting the wires, the wires are passed from the inside of the guide cylinder 7 into the inside of the power connection shell 1, and the two cables inside the wires are respectively inserted into the power connection slots 6 inside the two plug-ins 5, and then the two pressing plates 11 are rotated, and the pressing plates 11 drive the pressing blocks 10 to rotate, and the two cables are respectively pressed on the surfaces of the two support blocks 9 by the pressing plates 11, thereby playing a pressing and holding role on the two cables inside the wires, effectively improving the stability of the cables, and thereby improving the tensile strength of the wires. In addition, while the pressing plates 11 are rotating, the wires inside the cables are pressed and held inside the power connection slots 6 by the power connection mechanism 2, thereby realizing the connection between the wires and the plug-ins 5. After the pressing block 10 presses the cables on the surface of the support block 9, the pressing plate 11 is pressed and held by the pressing mechanism 3, thereby preventing the pressing plate 11 from rotating. It plays a fixing role on the pressure plate 11, thereby effectively ensuring the pressing effect of the pressure block 10 on the cable, and after the pressure plate 11 presses the cable on the surface of the support block 9, the inflation mechanism 4 will inflate the buffer airbag 8, thereby expanding the inflatable airbag 43. The inner wall of the inflatable airbag 43 fits tightly with the wire, on the one hand, it improves the sealing performance between the wire and the guide cylinder 7, thereby preventing moisture or dust in the air from entering the power connection shell 1, and on the other hand, it can play a buffering role on the wire, thereby reducing the wear between the wire and the guide cylinder 7, and effectively improving the service life of the wire. When the wire is connected to the power, the cover body can be connected to the power connection shell 1, wherein the cover body can be connected to the power connection shell 1 by a snap-on method, and can also be connected to the power connection shell 1 by bolts and nuts, and there is no limitation here.

[0025] See also Figure 3The power connection mechanism 2 includes a push rod 24 that penetrates the side wall of the plug 5, one end of the push rod 24 is located inside the power connection slot 6, and the other end of the push rod 24 is fixed with a push plate 22, and the push plate 22 is connected to the outer wall of the plug 5 through a first elastic member 23, wherein a convex block 21 capable of squeezing the push plate 22 is fixed to the outside of the pressure plate 11;

[0026] When connecting the wires, the two cables inside the wires are peeled respectively to expose the wires inside the cables, and then the wires inside the two cables are inserted into the two power connection slots 6. At this time, the pressure plate 11 rotates and drives the protrusion 21 to rotate. During the rotation of the protrusion 21, the abutment plate 22 will be squeezed, and the abutment plate 22 drives the abutment rod 24 to move toward the inside of the power connection slot 6. When the pressure block 10 presses the cable on the surface of the support block 9, the abutment rod 24 just presses the wires inside the cable against the inner wall of the power connection slot 6. There is no need for the staff to screw the screws to connect the wires, which is convenient for the staff to quickly connect the wires. The abutment rod 24 and the abutment plate 22 can be made of insulating materials, and the first elastic member 23 can be a spring, which can ensure the initial position of the abutment rod 24 and the abutment plate 22, so that the staff can insert the wires into the power connection slot 6.

[0027] See also Figure 4 The pressing mechanism 3 includes a limit frame 31 arranged inside the power connection shell 1, and a groove body 32 is arranged inside the limit frame 31. The end of the limit frame 31 away from the pressing plate 11 is connected to a buffer component. When the pressing block 10 completes the pressing of the wire, under the action of the buffer component, one end of the limit frame 31 presses the pressing plate 11, thereby limiting the rotation of the pressing plate 11, and the other end of the limit frame 31 presses the cable on the surface of the pressing block 10, thereby bending the cable;

[0028] When the wires are connected to the power supply, the cables inside the wires can be passed through the groove 32 inside the limit frame 31. When the pressure block 10 presses the cables on the surface of the support block 9, the limit frame 31 automatically resets under the action of the buffer assembly. At this time, one end of the limit frame 31 is tightly fitted with the side wall of the pressure plate 11, thereby limiting the pressure plate 11, thereby limiting the rotation of the pressure plate 11, ensuring the pressure holding effect of the pressure block 10 on the cables, and the other end of the limit frame 31 can press the cables on the surface of the pressure block 10, and the limit frame 31 can press the cables on the surface of the pressure block 10 while bending the cables, effectively improving the stability of the cables and further improving the tensile strength of the wires.

[0029] See also Figure 4The buffer assembly includes a baffle 33 fixedly connected to the inner wall of the power connection shell 1, a slide bar 35 runs through the inside of the baffle 33, one end of the slide bar 35 is fixedly connected to the limit frame 31, and a second elastic member 34 is provided outside the slide bar 35, and the two ends of the second elastic member 34 are respectively fixedly connected to the limit frame 31 and the baffle 33;

[0030] When connecting the wires to electricity, the staff pushes the limit frame 31 so that the limit frame 31 is away from the pressure plate 11. At this time, the second elastic member 34 is in a compressed state. The second elastic member 34 can be a spring. When the wires are connected to electricity, the staff releases the limit frame 31, and the limit frame 31 automatically resets under the action of the second elastic member 34, so that the pressure block 10 and the pressure plate 11 are stuck inside the limit frame 31. On the one hand, the stability of the pressure block 10 and the pressure plate 11 is guaranteed, and on the other hand, the cable is bent, wherein the slide rod 35 can play a limiting role on the limit frame 31, effectively improving the stability of the limit frame 31 when moving.

[0031] See also Figure 4 The inflation mechanism 4 includes an inflatable airbag 43 which is fixedly connected to the inner wall of the power connection shell 1 and is symmetrically distributed. The inflatable airbag 43 is connected to an air pipe 45. The other end of the air pipe 45 passes through the limit cylinder and is connected to the buffer airbag 8. An extrusion component is provided inside the power connection shell 1. When the pressing block 10 presses the wire on the surface of the support block 9, the extrusion component is used to squeeze the inflatable airbag 43;

[0032] When the pressing block 10 presses the cable against the surface of the supporting block 9, the pressing block 10 inflates the inflatable airbag 43 through the extrusion assembly, so that the gas inside the inflatable airbag 43 enters into the buffer airbag 8 through the air pipe 45, and the inflatable airbag 43 expands and fits tightly with the wire.

[0033] See also Figure 4 The extrusion assembly includes a pressure rod 41 that penetrates the support block 9 and is symmetrically distributed. A movable plate 42 is fixed to one end of the pressure rod 41 away from the support block 9. One side of the movable plate 42 is in contact with the inflatable airbag 43, and the other side of the movable plate 42 is connected to the support block 9 through a third elastic member 44.

[0034] The pressing block 10 will also squeeze the pressing rod 41 in the process of pressing the cable against the surface of the supporting block 9. The pressing rod 41 drives the movable plate 42 to move, thereby squeezing the inflatable airbag 43. When the pressing block 10 presses the cable against the surface of the supporting block 9, the buffer airbag 8 is fully expanded and fits tightly with the wire. When the wire is connected to the power supply, the cable can be passed through between the two pressing rods 41. The cable is limited by the pressing rod 41, thereby limiting the up and down movement of the cable, further ensuring the stability of the cable.

[0035] See also Figure 4A plurality of fixing blocks 46 are fixed on the inner wall of the power connection housing 1, and the air pipe 45 passes through the inside of the fixing block 46 and is fixedly connected to the fixing block 46;

[0036] The air pipe 45 is fixed by the fixing block 46 to prevent the air pipe 45 from moving, which can effectively prevent the inside of the power connection housing 1 from being too messy.

[0037] Working principle: When the power plug is connected to the wire, the wire is passed through the guide cylinder 7 into the power connection shell 1, and the two cables inside the wire are respectively inserted into the power connection slots 6 inside the two plug pieces 5, and then the two pressing plates 11 are rotated, and the pressing plates 11 drive the pressing blocks 10 to rotate, and the two cables are respectively pressed on the surfaces of the two supporting blocks 9 by the pressing plates 11, thereby playing a pressing and holding role on the two cables inside the wire, effectively improving the stability of the cable, thereby improving the tensile strength of the wire, and the pressing plate 11 will also drive the convex The block 21 rotates, and the convex block 21 will squeeze the plate 22 during the rotation process, and the plate 22 drives the rod 24 to move toward the inside of the power connection slot 6. When the pressing block 10 presses the cable on the surface of the support block 9, the rod 24 just presses the wire inside the cable on the inner wall of the power connection slot 6, thereby connecting the wires. There is no need for the staff to screw the screws to connect the wires, which is convenient for the staff to quickly connect the wires. When the pressing block 10 presses the cable on the surface of the support block 9, the pressing plate 11 and the pressing block 10 are limited by the limit frame 31, and the limit frame 3 One end of the retaining frame 31 is tightly fitted with the side wall of the pressing plate 11, thereby limiting the pressing plate 11, thereby limiting the rotation of the pressing plate 11, ensuring the pressing effect of the pressing block 10 on the cable, and the other end of the limiting frame 31 can press the cable on the surface of the pressing block 10, and the limiting frame 31 can press the cable on the surface of the pressing block 10 while also bending the cable, effectively improving the stability of the cable and further improving the tensile strength of the wire. In addition, the pressing block 10 will also squeeze the pressing rod 41 in the process of pressing the cable on the surface of the support block 9, and the pressing rod 41 The movable plate 42 is driven to move, thereby squeezing the inflatable airbag 43, so that the gas inside the inflatable airbag 43 enters into the buffer airbag 8 through the air pipe 45. When the pressing block 10 presses the cable against the surface of the supporting block 9, the buffer airbag 8 is completely expanded and fits tightly with the wire. On the one hand, the sealing performance between the wire and the guide cylinder 7 is improved, thereby preventing moisture or dust in the air from entering the power connection shell 1. On the other hand, it can play a buffering role for the wire, thereby reducing the wear between the wire and the guide cylinder 7, and effectively improving the service life of the wire.
