[0002] Socket distribution boxes are suitable for civil buildings, comprehensive commercial buildings, municipal administration, communications, industrial and mining energy, rail transit, corporate workshops and other fields. They are connection equipment for expanding power supply. In the socket distribution boxes currently on the market, the sockets are generally set on the box door.

[0003] In the Chinese patent with publication number CN219371598U, it is mentioned that a socket installation area is set on the front of the box body, and the socket installation area is independent of the box door. Compared with the prior art, the plugging and unplugging of the plug will not cause the box door to deform or be damaged, and the socket installation area is integrated with the box body, and the structure is more stable;

[0004] In actual use, although the plugging and unplugging actions can prevent damage to the movable cabinet door, due to the fixed installation, when the electrical equipment needs power, it needs to be placed near the distribution box. In places with a large range of use, such as construction site power supply or field power supply, the construction location and the electrical equipment are dispersed and far away from each other. When electricity is needed at the same time, the fixed distribution box cannot supply power due to its small power supply coverage and the distance exceeds the length of the power cord of the electrical equipment itself, so its use is limited.

[0012] Furthermore, the cable organizer also includes a ring, which is sleeved and installed on the outside of the wire, the inner wall of the ring is in sliding contact with the outer wall of the wire, and the outer diameter of the ring decreases toward one end of the socket.

[0013] Furthermore, the cable organizer also includes an arc plate, the end of the arc plate is bent and extended toward the direction of the wire axis, an end rod is installed on the opposite side of the arc plate, and a clamp is installed at the position of the cover plate corresponding to the end rod.

[0014] Furthermore, a threaded groove is provided at the overlapping position of the connecting rod and the cover plate, and the rear end of the connecting rod and the socket is protruding from the inner plate. A limiting ring is installed at the protruding position of the connecting rod, and the outer diameter of the limiting ring is larger than the inner diameter of the socket.

[0015] Furthermore, the power module includes an input connector, the input connector is connected to a junction box via a wiring harness, a power regulator is installed in series between the input connector and the junction box, and the junction box is electrically connected to the extension mechanism.

DETAILED DESCRIPTION

[0033] 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.

[0034] like Figure 1-Figure 10 As shown, this embodiment provides an improved socket distribution box, including a protection box 1 and a power module 3. In the use scenario of construction sites or outdoor camping, many electrical devices are used, but the power supply is relatively single, so the socket distribution box is required to provide sufficient power supply nodes, wherein the power module 3 is installed in the protection box 1, and the power module 3 is connected to the main power supply. At the same time, a power connection head 2 is installed on the side wall of the protection box 1. There are multiple power connection heads 2, which are arranged around the protection box 1, and multiple plug-in nodes can be provided around to facilitate power supply for multiple electrical devices. In addition, for the use scenario where the electrical devices are relatively dispersed, the power connection head 2 is movably connected to the protection box 1, and the power connection head 2 can be removed from the side wall of the protection box 1 and pulled closer to the electrical device. An extension mechanism 4 is installed between the power connection head 2 and the power module 3, and the extension mechanism 4 can flexibly extend and adapt the distance between the power connection head 2 and the power module 3, and simultaneously power multiple devices that are far away from each other, thereby improving the power distribution coverage. Using one protection box 1 can meet the power supply needs of dispersed electrical devices, and the use is more flexible;

[0035] In order to expand the power supply range, this solution makes specific improvements to the docking head 2 and the extension mechanism 4 to achieve a flexible power supply effect;

[0036] For connector 2, refer to Figure 2The electrical connector 2 includes a socket 21, which is a finished product purchased from the market. A double-plug, three-plug or six-hole industrial socket 21 can be purchased according to usage requirements. A sealing cover is installed at the end of the socket 21 through a torsion spring rotation. The port of the socket 21 can be sealed when not in use to prevent debris from entering. During installation, a cover plate 22 is installed at the end of the socket 21. The middle part of the cover plate 22 has a round hole, which is convenient for the socket 21 to be installed in the middle of the cover plate 22. The socket 21 and the cover plate 22 are assembled and connected by a connecting rod 24. The connecting rod 24 fixes the socket 21 and the cover plate 22 into a whole. At the same time, an installation opening is opened at the vertical side wall of the protective box 1, and an inner plate 23 is installed at the position of the installation opening. The inner plate 23 has a middle hole 26 corresponding to the socket 21. When not in use, refer to Figure 5 The inner plate 23 is provided with a plug hole 28 corresponding to the connecting rod 24. The connecting rod 24 is inserted into the plug hole 28. At this time, the socket 21 is inserted into the middle hole 26 of the inner plate 23. The cover plate 22 and the inner plate 23 are vertically fitted. The position of the cover plate 22 is fixed by the friction between the inner wall of the plug hole 28 and the outer wall of the circumference of the connecting rod 24, thereby stably connecting the socket 21 and the protective box 1. When in use, refer to Figure 6 and Figure 7 , pull the socket 21 away from the protective box 1, and pull the socket 21 out of the middle hole 26 of the inner plate 23. At this time, the connecting rod 24 is separated from the socket 28, so that the socket 21 is in an active state, and can be easily moved near the electrical equipment to supply power;

[0037] For the extension mechanism 4, refer to Figure 2 When the socket 21 is pulled away from the protection box 1, the extension mechanism 4 can ensure that the position of the protection box 1 remains unchanged to supply power to the remote electrical equipment, wherein the extension mechanism 4 includes a bobbin 41, the bobbin 41 is cylindrical, and the bobbin 41 is provided with a wire 42 wound along the circumferential side wall, and the wire 42 can be retracted and released by rotating forward and reverse. During installation, the wire 42 is installed in series between the power supply head 2 and the power module 3. The wire 42 is made of a flexible material so that it can be wound around the outside of the bobbin 41. The wire 42 transfers the electric energy at the power supply module 3 to the power supply head 2. A wire organizer 43 is installed on the outside of the wire 42. When the power supply head 2 is pulled outward, refer to Figure 6 and Figure 7 The wire 42 is taken out from the outside of the spool 41 and pulled out of the protective box 1 through the middle hole 26 in the middle of the inner plate 23. The wire organizer 43 is separated between the wire 42 and the inner plate 23 to prevent the wire 42 from directly contacting and abrading the inner wall of the inner plate 23, thereby ensuring the stability of the long-term retraction and release operation of the wire 42. Fig. 9The inner plate 23 is provided with a sliding opening 29 corresponding to the wire organizer 43, and the wire organizer 43 passes through the inner plate 23 through the sliding opening 29. When winding the wire, the reel 41 is reversed to wind the wire 42 back to the middle of the reel 41, and when winding, the wire organizer 43 can be reciprocated in the sliding opening 29, so that the wire 42 is evenly dispersed and wound on the entire circumferential side wall of the reel 41, avoiding the waste of space of the reel 41 caused by the wire 42 only being wound in the middle, and preventing the wire 42 from being stuck due to the large diameter of the wire 42 after winding and contacting the protective box 1. In the process of winding the wire, refer to Figure 8 , the wire 42 will first contact the wire organizer 43 and then enter the protection box 1. The wire organizer 43 blocks the debris outside the wire 42 outside the protection box 1 to ensure the cleanliness of the inside of the protection box 1 and the outer wall of the wire 42, and prevents the debris from entering and blocking the wire spool 41, causing the wire 42 to be retracted and released unsmoothly. Figure 5 When the wire 42 is gathered, the connecting rod 24 is plugged into the socket 28, and the cover plate 22 stably seals the middle hole 26 in the middle of the inner plate 23 to prevent the socket 21 from falling off. At the same time, the cover plate 22 is squeezed and contacted with the end of the cable organizer 43, and the cable organizer 43 is pressed between the cover plate 22 and the spool 41. The pressure of the cover plate 22 on the cable organizer 43 is used to press the spool 41 and the wire 42 to avoid the spool 41 from rotating independently during transportation, and to prevent the wire 42 from freely loosening from the spool 41 and causing it to be entangled and knotted inside the protective box 1, ensuring that it can still be smoothly pulled out and used after long-term transportation and carrying, which is convenient for transportation and has a stable structure.

[0038] In a further embodiment, in order to ensure that the wire organizer 43 can reciprocate to evenly wind the wire 42 around the circumferential side wall of the bobbin 41, a specific configuration is provided, referring to Figure 2 and Fig. 9 The cable organizer 43 passes through the inner plate 23 via the sliding opening 29, the sliding opening 29 is arranged horizontally, and the left and right width of the sliding opening 29 is equal to the left and right width of the spool 41, wherein the spool 41 is arranged horizontally in the protective box 1, the sliding opening 29 extends horizontally along the axial direction of the spool 41, and the cable organizer 43 can slide horizontally along the sliding opening 29, so that the cable organizer 43 can slide left and right along the axial direction of the spool 41, and the wire 42 is movably inserted into the cable organizer 43, and the cable organizer 43 moves left and right, so that the wire 42 can be evenly arranged. It is wound around the circumferential outer wall of the bobbin 41. At the same time, outward-turned convex edges are installed on the left and right ends of the bobbin 41. The outer diameter of the two ends of the bobbin 41 is increased by the outward-turned convex edges, and an inward-concave wire groove is formed in the middle of the bobbin 41. The wire 42 in the middle can be limited to prevent the wire 42 from falling off from the circumferential side wall of the bobbin 41 when it is wound to the end of the bobbin 41, and the width of the wire groove is ensured to be consistent with the left and right moving range of the cable organizer 43, so as to ensure that the position of the wire groove is fully utilized when the wire 42 is wound in multiple layers.

[0039] In a further embodiment, in order to ensure the connection between the cable organizer 43 and the inner plate 23 is stable and avoid falling off, refer to Figure 5 and Figure 6 The middle part of the slide 29 is horizontally slidably installed with a limit pin 44 along the extension direction. The limit pin 44 is cylindrical. A rectangular groove cooperating with the limit pin 44 is provided inside the top and bottom of the slide 29 to ensure that the limit pin 44 can slide left and right in the slide 29. At the same time, the cable organizer 43 includes a right-angle frame 431. A limit hole 434 cooperating with the limit pin 44 is provided in the horizontal section of the right-angle frame 431. The limit pin 44 passes through the right-angle frame 431 through the limit hole 434, and the right-angle frame 431 can be limited forward and backward. When the jack 28 of 3 is plugged in, the cover plate 22 is tightly attached to the inner plate 23, and the cover plate 22 squeezes the end of the right-angle frame 431 to press the cable organizer 43 as a whole into the protective box 1. At this time, the limit pin 44 is at the end of the limit hole 434 close to the cover plate 22, so that the cable organizer 43 can be sufficiently close to the wire shaft 41 to stably press the wire 42. When the wire 42 is pulled out, the cable organizer 43 will be synchronously pulled out of the protective box 1. At this time, the limit pin 44 is at the end of the limit hole 434 away from the cover plate 22, and the right-angle frame 431 can extend out of the protective box 1. Figure 7 As the cover plate 22 continues to move away from the protective box 1, the cover plate 22 separates from the right-angle frame 431. At this time, the wire 42 rubs the cable organizer 43 to make it close to the inner plate 23, and the cable organizer 43 is stably separated from the spool 41. During the release of the wire 42, ensure that the cable organizer 43 does not get close to the spool 41 to avoid poor release of the wire 42.

[0040] In a further embodiment, referring to Fig.10 , discloses a specific configuration of a cable organizer 43, the cable organizer 43 also includes a ring 433, the ring 433 is made of rubber material, the ring 433 is sleeved and installed on the outside of the wire 42, and the inner wall of the ring 433 is hardened to reduce the roughness, avoid excessive friction with the outer wall of the wire 42 resulting in poor retraction of the wire 42, the hardened inner wall of the ring 433 is more wear-resistant, and the service life is improved. When the wire 42 is pulled out of the protective box 1, the ring 433 will be inserted into the middle hole 26 of the inner plate 23, and the front and rear length of the ring 433 is greater than the thickness of the inner plate 23, ensuring that the ring 433 can stably separate the wire 42 and the inner plate 23. When the wire 42 is wound back on the spool 41, the position of the cable organizer 43 can be controlled by hand, refer to Figure 7 The inner wall of the ring 433 is in sliding contact with the outer wall of the wire 42. When the wire 42 enters the protective box 1 through the ring 433, the ring 433 will push down the debris adhered to the outer wall of the wire 42. The end of the ring 433 extends out of the inner plate 23 for a distance. After the debris is blocked and separated from the outer wall of the wire 42, it will fall from the outside of the middle hole 26, effectively preventing the debris from entering the protective box 1 and ensuring the cleanliness of the inside of the protective box 1. The outer diameter of the ring 433 is reduced at one end toward the socket 21. When large debris such as weeds are entangled, the sharper end can be inserted into the gap between the debris and the wire 42, so the debris can be cleaned smoothly.

[0041] In a further embodiment, referring to Figure 5 and Fig.10 In order to achieve the limitation of the wire organizer 43 to the wire spool 41 during transportation, a specific configuration is disclosed. The wire organizer 43 also includes an arc plate 432, which is arranged at the center of the wire spool 41 to ensure that the distance to the wire spool 41 is the shortest. At the same time, the end of the arc plate 432 is bent and extended toward the wire spool 41 to form a quarter-ring shape, which adapts to the arc-shaped outer contour of the wire spool 41 and the wire 42 after winding, and can increase the contact area and fit when in contact, effectively improve the friction and adaptability to the bending curvature of the wire 42, and ensure the The bobbin 41 is stabilized by friction limit. During transportation, the cover plate 22 and the inner plate 23 are tightly attached. At this time, an end rod 435 is installed on the opposite side of the arc plate 432, and a clamp 25 is installed on the cover plate 22 corresponding to the end rod 435. The end rod 435 is in the middle of the clamp 25, and the clamp 25 is inserted into the slide 29. The outer wall of the clamp 25 rubs against the inner wall of the slide 29, which can fix the position of the cover plate 22. The friction between the connecting rod 24 and the socket 28 can prevent the cover plate 22 from separating from the inner plate 23 during bumpy transportation, thereby ensuring the stable limit of the bobbin 41. Figure 6 When the cover plate 22 and the socket 21 are pulled out of the protective box 1, the cable organizer 43 can be stably brought out of the protective box 1 by the clamping connection between the clamp 25 and the end rod 435. After the wire 42 is pulled out, the cable organizer 43 extends a certain distance. When the wire 42 is subsequently rolled up, the handheld cable organizer 43 can be conveniently moved back and forth to evenly wind the wire and smoothly clean the wire 42.

[0042] In a further embodiment, since the connecting rod 24 needs to fix the cover plate 22 and the socket 21 and be movably connected with the inner plate 23, a specific configuration of the connecting rod 24 is disclosed, referring to Figure 8 A threaded groove is provided at the overlapped position of the connecting rod 24 and the cover plate 22, and the cover plate 22 also has a thread at the position corresponding to the connecting rod 24. The connecting rod 24 passes through the bolt hole at the edge of the socket 21 and is screwed with the cover plate 22 through the thread to press the socket 21 and the cover plate 22 tightly. At the same time, the connecting rod 24 is extended for a section at one end facing the inner plate 23. After the connecting rod 24 is plugged into the socket 28, the end of the connecting rod 24 will pass over the vertical side wall of the inner plate 23 and protrude from the inner plate 23. In addition, a limit ring 27 is installed at the protruding position of the connecting rod 24. Figure 5The outer diameter of the limit ring 27 is larger than the inner diameter of the socket 28. After insertion, the limit ring 27 will be stuck in the port position of the socket 28 away from the cover plate 22. The connecting rod 24 and the inner plate 23 are locked through the compressive deformation of the limit ring 27, and the connecting rod 24 can be squeezed in the direction away from the cover plate 22, thereby improving the tightness of the crimping between the cover plate 22 and the inner plate 23, adapting to the bumpy scenes of construction sites and outdoor tours, and the limiting is tighter. When the socket 21 is pulled, the elastic limit ring 27 can be compressed and deformed, and can be smoothly pulled out of the socket 28 without the need for unlocking operation. While ensuring the stability of the locking, the pulling action is more convenient.

[0043] In a further embodiment, referring to Figure 3 The power module 3 includes an input connector 31. The input connector 31 is provided with two, which are connected to two different plugs, such as a vehicle-mounted adapter and an industrial adapter, so as to facilitate the connection with the connector of the main power harness. The input connector 31 is arranged on both sides of the lower part of the protective box 1 to ensure that the power harness can be directly placed on the ground to avoid falling off due to gravity. At the same time, the input connector 31 is connected to a junction box 32 through a wiring harness. The junction box 32 adopts a one-to-eight junction structure. The junction box 32 is electrically connected to the extension mechanism 4, and can supply power to eight sockets 21 at the same time. In addition, a power regulator 33 is installed in series between the input connector 31 and the junction box 32. The power regulator 33 can control the fluctuation of the input voltage to ensure the safety and stability of the power supply. The power regulator 33 is placed inside the protective box 1 for perfect protection.

[0044] In a further embodiment, to further ensure safety in use, refer to Figure 2 An air switch 6 is installed between the power module 3 and the extension mechanism 4. There are eight air switches 6, which is the same as the number of the sockets 21. When the socket 21 or the electrical equipment is short-circuited, the air switch 6 can be automatically disconnected to ensure safe use. At the same time, a rotating connector 45 is embedded in the axial position of the spool 41. When the spool 41 is rotated forward and backward, the wire 42 will rotate synchronously with the spool 41. At this time, the air switch 6 and the wire 42 are electrically connected through the rotating connector 45, and the rotating connector 45 can use existing high-voltage conductive products, which can be powered by AC power or higher voltage to ensure rotational conduction between the rotating wire harnesses, avoid twisting of the wire 42 due to rotation, and ensure the stable position of the wire 42. One end of the rotating connector 45 is inserted into the end of the spool 41 and the other end is fixed to the inner wall of the protective box 1. The end of the spool 41 can be limited by the rotating connector 45 to ensure the stable rotation of the spool 41.

[0045] In a further embodiment, referring to Figure 2The protective box 1 includes a box body 11, which is made of insulating material and has a built-in cavity to accommodate the equipment and protect it from bumps and impacts. An inner frame 13 is installed on the inside of the box body 11, and the inner frame 13 divides the internal cavity into eight independent spaces, which can ensure that the wires 42 are independent of each other, avoid entanglement, overlap or interference with each other, and ensure the smooth retraction and release of the wires 42. At the same time, the spool 41 is rotatably installed between the box body 11 and the inner frame 13, and a through hole is provided in the side wall of the box body 11, and a bearing is installed in the through hole, so that the spool 41 can be rotationally limited. In order to facilitate the use of retracting and releasing the wire, a crank can be provided at one end of the spool 41 located on the outside of the box body 11 to manually retract and release the wire 42, and a motor can be installed at the end of the spool 41, and the motor is connected to a control button, and the electric retraction and release of the spool 41 is controlled by the button. Manual and electric can be selected according to usage requirements.

[0046] In a further embodiment, referring to Figure 1 and Figure 2 The protection box 1 also includes a top plate 12, which is installed on the top of the inner side of the protection box 1 to separate the operating space. The air switch 6 is embedded in the middle of the top plate 12. When the air switch 6 trips and the circuit fault is resolved, the switch can be manually closed to quickly restore power. A top cover 5 is movably installed at the top plate 12 of the box body 11. The top cover 5 is installed on the top of the box body 11 through a hinge and is equipped with a lock. During transportation and carrying, the position of the air switch 6 can be sealed to avoid accidental touch. A handle is fixedly installed on the end face of the top cover 5 for easy carrying.

[0047] The working principle of this embodiment is as follows:

[0048] When carrying, the socket 21 is pressed against the end of the inner plate 23 by the cover plate 22, the connecting rod 24 is inserted into the jack 28, and is locked and limited by the limit ring 27, and the wire 42 wound around the outer wall of the spool 41 is pressed by the wire organizer 43 to prevent the wire 42 from being loosened and tangled in the protective box 1 due to bumps during transportation;

[0049] When in use, the protection box 1 is connected to the main power supply through the power module 3, so that the protection box 1 becomes a power supply relay device, and the plug of the power-consuming device is inserted into the socket 21, and multiple sockets 21 are used for simultaneous power supply, which can drive multiple power-consuming devices to work at the same time. When a fault occurs, the air switch 6 can disconnect the faulty socket 21 to protect the independent normal operation of other sockets 21, and protect the safety of the power-consuming device and the power supply device;

[0050] When supplying power to dispersed electrical equipment, the socket 21 can be pulled out from the inner plate 23, the connecting rod 24 can be separated from the socket 28, the wire 42 can be pulled out of the protection box 1, and the socket 21 can be pulled near the electrical equipment, which increases the power supply coverage of the device and makes it more flexible to use;

[0051] When recovering the wire 42, the handheld wire organizer 43 moves back and forth at the sliding mouth 29 of the inner plate 23, and the axial sliding along the spool 41 can make the wire 42 evenly wound on the circumferential outer wall of the spool 41, ensuring that the wire 42 is wound dispersedly to avoid local stacking and excessive contact with the inner wall of the protective box 1 causing wear. The wire organizer 43 extends out of the protective box 1 for a distance, and can push down the debris adhered to the outer wall of the wire 42 before the wire 42 enters the protective box 1, to prevent the debris from entering the interior of the protective box 1 and causing the wire 42 to be stuck, thereby improving the stable use in the field and on the soil environment of the construction site.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
