Description

Technical Field

[0001] The invention relates to the technical field of socket shells, and in particular to a waterproof power strip shell and a production method thereof. Background Art

[0002] Waterproof power strips are widely used in fire-fighting equipment, industrial fields and other environments with water to ensure the safe use of electrical equipment in humid environments. The waterproof power strip is mainly composed of an internal socket body, a waterproof ring, a sealant, and a power strip outer shell. The main outer shell of the waterproof power strip is mainly composed of two shells assembled with threads, and the upper part of the outer shell is also provided with a triangular interface of the socket. The outer shell of the waterproof power strip is mainly molded by injection molding. The use of engineering plastic material makes the outer shell have good mechanical strength and corrosion resistance, can adapt to various harsh environments, and the installation gap is small and has a certain waterproof effect.

[0003] However, there is a gap at the plug insertion position of the waterproof power strip shell. After the plug is inserted, the line will shake between the power strip and the line when moving, causing a gap. When used in an environment with high moisture, the gap between the plug and the power strip is easily penetrated by moisture, and the moisture enters the inside of the power strip along the metal joint of the plug. In addition, the power strip shell is divided into two parts, upper and lower parts. There will be a gap at the connection during assembly. A small amount of moisture can easily enter the inside of the power strip through the gap at the connection, resulting in low waterproof performance of the power strip. Summary of the invention

[0004] The present invention provides a waterproof power strip housing and a production method thereof, which overcomes the shortcomings described in the background technology.

[0005] The technical solution adopted by the present invention to solve its technical problem is: A waterproof power strip housing and a production method thereof, comprising the wire, a base shell, a waterproof cover, a power strip board, a closing cover, and a first rubber block, wherein the first rubber block is arranged on the left and right sides of the waterproof cover, the base shell and the closing cover are matched with each other to form a socket, and the wire is connected to the inside from the sides of the base shell and the closing cover, and five power strip boards are equidistantly arranged on the surface of the closing cover, and when the first rubber blocks on both sides are pressed, the waterproof cover is placed on the surface of the closing cover, so that the two first rubber blocks are engaged on the surface of the closing cover, and at the same time, the lower surface of the waterproof cover presses against the surface of the closing cover; The waterproof cover is provided with a flat plate, a sealing structure, a movable groove, and a rubber plate. The movable groove is arranged on the surface of the flat plate. Five sealing structures are arranged equidistantly inside the flat plate. When the waterproof cover is against the surface of the closed cover, each sealing structure corresponds to the position of the strip board. The rubber plate is attached to the lower side of the flat plate. When the sealing structure is opened and closed, the plug is squeezed in from above the strip board and passes through the strip board into the closed cover. At this time, the sealing structure is closed again and isolated from the outside world.

[0006] A preferred technical solution: the sealing structure is provided with a water retaining structure, a support plate, a channel plate, and a rotating plate. The channel plate is arranged on the side of the support plate, the support plate is arranged on the inner side of the plane plate, and the rotating plate is horizontally arranged on the upper end of the support plate. When the rotating plate rotates, the outer side of the rotating plate moves in the movable groove, and the rotating plate rotates counterclockwise and upward with the upper left end of the support plate as the center. The water retaining structure is arranged inside the channel plate. When the plug enters the support plate, the line on the side end of the plug squeezes in from the water retaining structure and isolates the plug.

[0007] A preferred technical solution: the rotating plate is provided with a limit rod, a glass plate, and a force-bearing plate. The force-bearing plate and the glass plate are located on the same horizontal line, and the force-bearing plate and the glass plate are arranged on the left and right sides of the limit rod. The limit rod hinge is arranged at the upper left end of the support plate. When the force-bearing plate is manually pressed, the glass plate rotates counterclockwise with the limit rod as the center, and the glass plate is separated from the edge of the support plate surface.

[0008] A preferred technical solution: a spring ring is arranged inside the limit rod, and when the glass plate contacts the surface of the support plate, the spring ring is in a compressed state, so that the glass plate is pressed against the surface of the support plate.

[0009] A preferred technical solution: a circle of rubber strip is provided at the edge of the lower end of the glass plate, and when the limiting rod is elastically compressed, the rubber strip at the lower end of the glass plate is pressed against the surface of the supporting plate.

[0010] A preferred technical solution: two arc plugs made of rubber are respectively provided on the sides of the base shell and the closing cover. After the wire passes through the connection between the base shell and the closing cover, the two arc plugs form a ring to press against the outside of the wire after the base shell and the closing cover are assembled.

[0011] A preferred technical solution: A hook is provided at the lower end of the first rubber block, and a slot is provided on the surface of the closing cover. The vertical positions of the hook and the slot correspond to each other. When the waterproof cover presses downward against the surface of the closing cover, the hook engages with the slot on the surface of the closing cover. After pressing the first rubber block on both sides of the waterproof cover, the hook is driven to tilt outward and disengage from the slot.

[0012] A preferred technical solution: the water retaining structure is provided with a polyethylene foam plate and a second rubber block, the polyethylene foam plate is arranged at the upper end of the second rubber block, and the polyethylene foam plate and the second rubber block are symmetrically arranged on the inner side of the channel plate. When the plug circuit squeezes the polyethylene foam plate, the plug circuit compresses the polyethylene foam plate, driving the polyethylene foam plate to deform and move outward, and making the plug circuit contact the curved surface of the second rubber block. At this time, three equally spaced second rubber blocks wrap the plug circuit.

[0013] A preferred technical solution: the surface of the polyethylene foam board is inclined at 5°, and the highest point close to one end of the rotating plate is level with the surface of the supporting plate, and when the rotating plate elastically presses the surface of the supporting plate, the rotating plate presses against the highest point of the polyethylene foam board.

[0014] A better technical solution: a trapezoidal rubber belt and a sponge strip are provided on the inner side of the base shell, and the trapezoidal rubber belt is attached to the inner wall of the upper end of the base shell, and the sponge strip is arranged on the outer side of the trapezoidal rubber belt. The upper end of the base shell is an "L" notch shape, and the trapezoidal rubber belt and the sponge strip are distributed around the notch at the upper end of the base shell.

[0015] A better technical solution: a sheath plate is provided at the lower end of the closing cover, and the sheath plate matches the notch at the upper end of the base shell. When the closing cover moves downward and splices with the base shell, the sheath plate is inserted into the notch at the upper end of the base shell and presses against the trapezoidal rubber belt under the compression of the sponge strip.

[0016] Based on the production method of the waterproof power strip housing, the construction method includes the following specific steps: S: First, use an injection molding machine to mold the corresponding shapes of the closing cover and the base shell. After trimming the appearance of the closing cover and the base shell, use strong glue to bond the trapezoidal rubber belt and the sponge strip to form a long strip. Then apply strong glue on the outside of the trapezoidal rubber belt and bond it to the "L"-shaped notch at the upper end of the base shell. When the wires are connected from the sides of the base shell and the closing cover, the base shell and the closing cover are spliced ​​together; S: Use an injection molding machine to mold the notch shape of the triangular plug of the strip plug board, and fix the strip plug board on the surface of the closed cover with threads; S: Use an injection molding machine to inject a shape consisting of a plane plate, a support plate and a channel plate, and the surface of the injected plane plate should have a movable groove. After the injection molding of the waterproof cover is completed, the hook is installed and fixed at the lower end of the first rubber block, and the inside of the first rubber block is glued to both sides of the plane plate with strong glue, and the rubber plate is glued to the bottom of the plane plate with strong glue. At this time, the combination of the waterproof cover, the first rubber block and the hook is completed; S: Hold and press the waterproof cover, so that the hook engages with the corresponding groove on the surface of the closed cover. At this time, the rubber plate at the lower end of the waterproof cover remains in a compressed state, and under the connection of the first rubber block, the rubber plate is pulled to keep the compressed state against the surface of the closed cover. At this time, the sealing structure corresponds to the power strip board, and the production and assembly of the waterproof power strip housing are completed.

[0017] Compared with the prior art, this technical solution has the following advantages: In the present invention, after the plug is inserted into the power strip at the sealing structure position, the waterproof cover is kept in a state of abutting against the surface of the closed cover under the connection of the first rubber block. At this time, the waterproof cover and the surface of the closed cover are compressed by the rubber plate, thereby preventing moisture from entering the edge of the plug on the power strip, and the sealing structure position closes the upper end of the plug and one end of the circuit, preventing external moisture from penetrating into the surface of the closed cover from above.

[0018] When the base shell and the closing cover in the present invention are assembled, the "L"-shaped notch at the upper end of the base shell is embedded by the sheath plate at the lower end of the closing cover, and the sheath plate slides in on the side of the sponge strip. At this time, there are trapezoidal rubber belts and sponge strips at the "L"-shaped notch. Therefore, after the sheath plate slides in on the side of the sponge strip, it squeezes the trapezoidal rubber belt and compresses it, so that the gap position at the assembly connection between the closing cover and the base shell is filled with the compression of the trapezoidal rubber belt. Therefore, the assembly of the base shell and the closing cover in the present invention avoids moisture from entering from the connection gap, prevents the interior from being disturbed by moisture and causing a short circuit, and enhances the waterproofness of the interior of the power strip shell.

[0032] like Figures 1 to 6 As shown, the present invention proposes a waterproof power strip housing and a production method thereof, comprising the wire 1, a base shell 2, a waterproof cover 3, a power strip board 4, a closing cover 5, and a first rubber block 6, wherein the first rubber block 6 is arranged on the left and right sides of the waterproof cover 3, the base shell 2 and the closing cover 5 are matched with each other to form a socket, and the wire 1 is connected to the inside from the sides of the base shell 2 and the closing cover 5, and the five power strip boards 4 are equidistantly arranged on the surface of the closing cover 5. When the first rubber blocks 6 on both sides are pressed, the waterproof cover 3 is placed on the surface of the closing cover 5, so that the two first rubber blocks 6 are engaged on the surface of the closing cover 5, and at the same time, the lower surface of the waterproof cover 3 presses against the surface of the closing cover 5; The waterproof cover 3 is provided with a plane plate 31, a sealing structure 32, a movable groove 33, and a rubber plate 34. The movable groove 33 is arranged on the surface of the plane plate 31, and five sealing structures 32 are arranged equidistantly inside the plane plate 31. When the waterproof cover 3 is against the surface of the closing cover 5, each sealing structure 32 corresponds to the position of the strip board 4, and the rubber plate 34 is attached to the lower side of the plane plate 31. When the sealing structure 32 is opened and closed, the plug is squeezed in from the top of the strip board 4, and the plug passes through the strip board 4 into the closing cover 5. At this time, the sealing structure 32 is closed again and isolated from the outside world.

[0033] In the present invention, after the plug is inserted into the power strip 4 at the sealing structure 32 position, the waterproof cover 3 is kept in contact with the surface of the closing cover 5 under the connection of the first rubber block 6. At this time, the waterproof cover 3 and the surface of the closing cover 5 are compressed by the rubber plate 34, thereby preventing moisture from entering the edge of the plug on the power strip 4, and the sealing structure 32 position closes the upper end of the plug and one end of the circuit, preventing external moisture from penetrating into the surface of the closing cover 5 from above.

[0034] Among them, the sealing structure 32 is provided with a water retaining structure 321, a support plate 322, a channel plate 323, and a rotating plate 324. The channel plate 323 is arranged on the side of the support plate 322, the support plate 322 is arranged on the inner side of the plane plate 31, and the rotating plate 324 is horizontally arranged on the upper end of the support plate 322. When the rotating plate 324 rotates, the outer side of the rotating plate 324 moves in the movable groove 33, and the rotating plate 324 rotates counterclockwise and upward with the upper left end of the support plate 322 as the center. The water retaining structure 321 is arranged inside the channel plate 323. When the plug enters the support plate 322, the side end line of the plug squeezes in from the water retaining structure 321 and isolates the plug.

[0035] Among them, the rotating plate 324 is provided with a limit rod 3241, a glass plate 3242, and a force plate 3243. The force plate 3243 and the glass plate 3242 are located on the same horizontal line, and the force plate 3243 and the glass plate 3242 are arranged on the left and right sides of the limit rod 3241. The limit rod 3241 is hinged at the upper left end of the support plate 322. When the force plate 3243 is manually pressed, the glass plate 3242 rotates counterclockwise with the limit rod 3241 as the center, and the glass plate 3242 is separated from the edge of the surface of the support plate 322.

[0036] In addition, a spring ring is provided inside the limiting rod 3241 . When the glass plate 3242 contacts the surface of the support plate 322 , the spring ring is in a compressed state, so that the glass plate 3242 is pressed against the surface of the support plate 322 .

[0037] In addition, a circle of rubber strip is provided at the edge of the lower end of the glass plate 3242 . When the limiting rod 3241 is elastically compressed, the rubber strip at the lower end of the glass plate 3242 presses against the surface of the supporting plate 322 .

[0038] In addition, two arc plugs made of rubber are respectively provided on the sides of the base shell 2 and the closing cover 5. After the wire 1 passes through the connection between the base shell 2 and the closing cover 5, the two arc plugs form a ring to press against the outside of the wire 1 after the base shell 2 and the closing cover 5 are assembled, so that the wire 1 is isolated from the outside at the connection between the base shell 2 and the closing cover 5.

[0039] In the present invention, the force-bearing plate 3243 on the rotating plate 324 is manually pressed to drive the glass plate 3242 to flip 90° around the limiting rod 3241. At this time, the force-bearing plate 3243 is pressed into the movable groove 33 and against the side of the support plate 322, thereby exposing the support plate 322 to allow the plug to enter. After releasing the pressure on the force-bearing plate 3243, the glass plate 3242 is reset under the elastic force of the limiting rod 3241, and the rubber strip at the lower end of the glass plate 3242 is compressed on the upper surface of the support plate 322 under the elastic force to prevent the entry of moisture. At the same time as the plug enters, the circuit on the side of the plug is squeezed from the position of the water retaining structure 321 into the channel plate 323 at the lower end, and a section of the circuit is isolated in the water retaining structure 321 to prevent the entry of external moisture.

[0040] Among them, a hook 8 is provided at the lower end of the first rubber block 6, and a slot is provided on the surface of the closing cover 5. The vertical position of the hook 8 corresponds to the slot. When the waterproof cover 3 presses downward against the surface of the closing cover 5, the hook 8 engages with the slot on the surface of the closing cover 5. After pressing the first rubber block 6 on both sides of the waterproof cover 3, the hook 8 is driven to tilt outward and disengage from the slot.

[0041] Among them, the water retaining structure 321 is provided with a polyethylene foam plate 3211 and a second rubber block 3212. The polyethylene foam plate 3211 is arranged at the upper end of the second rubber block 3212, and the polyethylene foam plate 3211 and the second rubber block 3212 are symmetrically arranged on the inner side of the channel plate 323. When the plug circuit squeezes the polyethylene foam plate 3211, the plug circuit compresses the polyethylene foam plate 3211, drives the polyethylene foam plate 3211 to deform and move outward, and makes the plug circuit contact the curved surface of the second rubber block 3212. At this time, the three second rubber blocks 3212 arranged equidistantly wrap the plug circuit.

[0042] In addition, the surface of the polyethylene foam board 3211 is inclined at 5°, and the highest point near one end of the rotating plate 324 is level with the surface of the support plate 322. When the rotating plate 324 elastically presses the surface of the support plate 322, the rotating plate 324 presses against the highest point of the polyethylene foam board 3211. When the rotating plate 324 and the water retaining structure 321 are in a closed state, the connection is sealed by the pressure between the highest point of the polyethylene foam board 3211 and the rotating plate 324 to prevent the formation of a gap that allows moisture to flow in.

[0043] In the present invention, when the plug enters the support plate 322, the side line of the plug squeezes the surface of the polyethylene foam plate 3211. At this time, the polyethylene foam plate 3211 is compressed outward and causes the side line of the plug to enter the arc position of the second rubber block 3212, so that the polyethylene foam plate 3211 is reset and drives the three second rubber blocks 3212 to wrap the outside of the side line of the plug. Under the elasticity of the second rubber blocks 3212 and the polyethylene foam plates 3211, the outside of the side line of the plug is separated into multiple sections. At the same time, the rubber plate 34 at the lower end of the channel plate 323 is pressed against the surface of the closing cover 5, driving the second rubber blocks 3212 to press downward. After the side line of the plug enters the position of the water retaining structure 321, it is isolated from the outside world, and the multi-section barrier of the second rubber blocks 3212 prevents moisture from entering the support plate 322 from the position of the water retaining structure 321.

[0044] Among them, a trapezoidal rubber belt 21 and a sponge strip 22 are provided on the inner side of the base shell 2, and the trapezoidal rubber belt 21 is attached to the inner wall of the upper end of the base shell 2, and the sponge strip 22 is arranged on the outer side of the trapezoidal rubber belt 21. The upper end of the base shell 2 is an "L" notch shape, and the trapezoidal rubber belt 21 and the sponge strip 22 are distributed around the notch at the upper end of the base shell 2.

[0045] Among them, the lower end of the closing cover 5 is provided with a sheath plate 51, which is matched with the notch at the upper end of the base shell 2. When the closing cover 5 moves downward and splices with the base shell 2, the sheath plate 51 is inserted into the notch at the upper end of the base shell 2 and presses against the trapezoidal rubber belt 21 under the compression of the sponge strip 22.

[0046] When the base shell 2 and the closing cover 5 are assembled in the present invention, the "L"-shaped notch at the upper end of the base shell 2 is embedded by the sheath plate 51 at the lower end of the closing cover 5, and the sheath plate 51 slides in on the side of the sponge strip 22. At this time, there are trapezoidal rubber strips 21 and sponge strips 22 at the "L"-shaped notch. Therefore, after the sheath plate 51 slides in on the side of the sponge strip 22, it will squeeze the trapezoidal rubber strip 21 and compress it, so that the assembly connection between the closing cover 5 and the base shell 2 is compressed and filled with the gap position of the trapezoidal rubber strip 21. After the base shell 2 and the closing cover 5 are assembled, they are threadedly tightened to prevent the base shell 2 and the closing cover 5 from loosening under the compression force of the trapezoidal rubber strip 21. Therefore, the assembly of the base shell 2 and the closing cover 5 in the present invention avoids moisture from entering from the connection gap, prevents the interior from being disturbed by moisture and short-circuited, and enhances the waterproofness of the interior of the power strip shell.

[0047] Based on the production method of the waterproof power strip housing, the construction method includes the following specific steps: S1: First, use an injection molding machine to mold the closing cover 5 into a shape corresponding to the base shell 2. After trimming the appearance of the closing cover 5 and the base shell 2, use strong glue to bond the trapezoidal rubber band 21 and the sponge strip 22 into a long strip, and then apply strong glue on the outside of the trapezoidal rubber band 21 and bond it to the "L"-shaped notch at the upper end of the base shell 2. When the wire 1 is connected from the sides of the base shell 2 and the closing cover 5, the base shell 2 and the closing cover 5 are spliced ​​with each other; S2: using an injection molding machine to mold the notch shape of the triangular plug of the strip board 4, and threading the strip board 4 to the surface of the closing cover 5; S3: Use an injection molding machine to inject a shape consisting of a plane plate 31, a support plate 322 and a channel plate 323, and the surface of the injected plane plate 31 should have a movable groove 33. After the injection molding of the waterproof cover 3 is completed, the hook 8 is installed and fixed at the lower end of the first rubber block 6, and the inside of the first rubber block 6 is glued to both sides of the plane plate 31 with strong glue, and the rubber plate 34 is glued to the bottom of the plane plate 31 with strong glue. At this time, the combination and production of the waterproof cover 3, the first rubber block 6 and the hook 8 are completed; S4: Hold and press the waterproof cover 3, so that the hook 8 engages with the corresponding groove on the surface of the closing cover 5. At this time, the rubber plate 34 at the lower end of the waterproof cover 3 remains in a compressed state, and under the connection of the first rubber block 6, the rubber plate 34 is pulled to keep the compressed state against the surface of the closing cover 5. At this time, the sealing structure 32 corresponds to the power strip board 4, so that the production and assembly of the waterproof power strip housing is completed.

[0048] It is necessary to explain that the power strip housing in the present invention is only suitable for connecting the triangular pin plug used for high-power electrical appliances.

[0049] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
