Description

Technical Field

[0001] The present application relates to the technical field of cable branch boxes, and in particular to a cable branch box. Background Art

[0002] The cable branch box is a special electrical connection device used for the collection and branching of cable lines in the power distribution system. The cable branch box can be placed outdoors, such as in commercial centers, industrial parks, urban residential areas and other places.

[0003] In the related art, a cable branch box includes a box body and a box door, wherein the box door is rotatably connected to the box body, a placement slot is provided on the box body, and power supply components are placed in the placement slot. A through hole connected to the placement slot is provided on the box body, and the through hole is provided for the cable to pass through.

[0004] Since the cable branch box is placed outdoors, the cables pass through the perforations. At this time, insects or mice on the ground may enter the box through the perforations, causing the small animals to damage the electrical components inside the cable branch box, affecting the normal use of the cable branch box. Summary of the invention

[0005] In order to improve the problem that small animals can easily enter the interior of the box through the perforations, the present application provides a cable branch box.

[0006] The present application provides a cable branch box, which adopts the following technical solution: A cable branch box comprises a box body and a box door, wherein the box door is rotatably connected to the box body, a placement slot is provided on the box body, a through hole connected to the placement slot is provided on the box body, an elastic plate for completely blocking the through hole is provided on the through hole, and the cable extends into the placement slot through the elastic plate.

[0007] By adopting the above technical solution, the perforation is blocked by an elastic plate, making it difficult for small animals to enter the placement groove directly through the perforation; the staff cuts the elastic plate, and the cable enters the placement groove through the elastic plate, allowing the elastic plate to abut the outer surface of the cable, so that the elastic plate can limit the distance between the cable and the perforation, thereby reducing the possibility of small animals crawling into the placement groove along the cable, and further reducing the damage caused by small animals to electrical components.

[0008] Optionally, a stop spring is provided on the elastic plate, a stop strip is provided on the stop spring, a stop plate is slidably connected to the stop strip, and the stop spring drives the stop plate to abut against the cable; when the stop plate abuts against the elastic plate, the elastic plate bends toward the ground.

[0009] By adopting the above technical solution, the stop spring drives the stop bar to move, allowing the stop plate to abut the cable. At the same time, the stop plate slides on the stop bar, and the staff drives the stop plate to move, allowing the stop plate to abut the elastic plate. At this time, the elastic plate bends toward the ground, making it difficult for small animals to push against the elastic plate to enter the placement groove, further reducing the possibility of small animals entering the placement groove.

[0010] Optionally, a fixing plate is provided on the elastic plate, a fixing piece is provided on the fixing plate, a first fixing groove and a second fixing groove are provided on the stop strip, and the fixing piece can be inserted into the first fixing groove or the second fixing groove; when the fixing piece is located in the first fixing groove, the stop strip abuts against the cable; when the fixing piece is located in the second fixing groove, the stop strip cannot abut against the cable.

[0011] By adopting the above technical solution, the fixing part is inserted into the first fixing groove, so that the fixing part limits the stop bar and restricts the stop bar from abutting the cable, so that the staff can pass the cable through the through hole to achieve the installation of the cable; the staff moves the fixing plate to disengage the fixing part from the second fixing groove. At this time, the stop bar is driven by the stop spring so that the stop bar can abut the cable, and then the staff moves the fixing plate to insert the fixing part into the first fixing groove. The fixing part limits the stop bar so that the stop bar can stably abut the cable, thereby greatly reducing the situation where small animals move the stop bar, so that the stop bar can more stably abut the cable.

[0012] Optionally, a moving bar is slidably connected to the stop bar, a moving groove for inserting the moving bar is provided on the stop plate, a moving inclined surface is provided on the moving bar, and the moving inclined surface is located in an insertion path of the fixing member into the first fixed groove; when the fixing member is inserted into the first fixed groove, the moving bar can be inserted into the moving groove, and at this time the stop bar abuts against the elastic plate.

[0013] By adopting the above technical solution, the movable inclined surface is located in the insertion path of the fixing member into the first fixed groove, so that the fixing member can drive the movable bar to move through the movable inclined surface, and the movable bar is inserted into the movable groove. The movable bar limits the stop bar, so that the stop bar can stably abut the elastic plate.

[0014] Optionally, a rotating bar is rotatably connected to the box body, and a moisture-proof sponge is provided on the rotating bar. The moisture-proof sponge can drive the rotating bar to rotate in the direction of the cable. A limit bar is slidably connected to the fixed plate, and the limit bar is used to limit the rotation of the rotating bar.

[0015] By adopting the above technical solution, the rotation of the rotating bar is restricted by the limit bar, so that the moisture-proof sponge cannot drive the rotating bar to rotate, thereby preventing the moisture-proof sponge from contacting the cable. If the cable has an accidental short circuit or the temperature is too high, the moisture-proof sponge does not catch fire and cause a fire; by moving the limit bar, the limit bar does not restrict the rotation of the rotating bar, so that the moisture-proof sponge drives the rotating bar to rotate, thereby allowing the moisture-proof sponge to contact the cable, allowing the moisture-proof sponge to absorb moisture, preventing moisture from spreading from the perforation to the placement groove, reducing the erosion of the cable by moisture, and allowing the cable to be better protected.

[0016] Optionally, the fixing member is slidably connected to the fixing plate, the limiting bar is arranged on the fixing member, and the fixing member includes a water-absorbing sponge; when the water-absorbing sponge absorbs sufficient water, the rotating bar can rotate; when the water-absorbing sponge does not absorb water, the limiting bar restricts the rotation of the rotating bar.

[0017] By adopting the above technical solution, when water spreads to the perforation, the water-absorbing sponge can absorb moisture. At this time, the weight of the water-absorbing sponge increases, allowing the water-absorbing sponge to drive the limit bar to move, so that the limit bar does not restrict the rotation of the rotation bar, thereby allowing the moisture-proof sponge to rotate smoothly, allowing the moisture-proof sponge to smoothly abut the cable, and then the staff does not need to manually move the limit bar. Through the water absorption of the water-absorbing sponge, the moisture-proof sponge can automatically rotate, so that the moisture-proof sponge can absorb moisture in time when the moisture spreads, further avoiding the erosion of the cable by moisture.

[0018] Optionally, a receiving groove is provided on the placement groove, a dehumidification bag is provided in the receiving groove, and the moisture-proof sponge blocks the opening of the receiving groove.

[0019] By adopting the above technical solution, the dehumidification bag is arranged in the receiving groove, and the moisture-proof sponge blocks the opening of the receiving groove, so that the moisture-proof sponge can limit the dehumidification bag from absorbing moisture in normal times. When the moisture-proof sponge is absorbing moisture, the dehumidification bag can dehumidify the moisture in the placement groove, further reducing the humidity in the placement groove and reducing the damage to electrical components caused by excessive humidity.

[0020] Optionally, a through hole connected to the placement slot is provided on the box door, a sliding bar is slidably connected in the through hole, a sliding bar is provided on the sliding bar, and the sliding spring drives the sliding bar to be inserted into the box; when the moisture-proof sponge abuts against the cable, the sliding bar protrudes from the box door.

[0021] By adopting the above technical solution, the sliding bar is driven to move by the sliding spring so that the sliding bar can be located inside the box, and the sliding bar does not protrude from the box; when the moisture-proof sponge abuts the cable, the moisture-proof sponge drives the sliding bar to move, so that the sliding bar protrudes from the box door. At this time, the staff can know whether water has spread inside the box by observing the position of the sliding bar, so that the staff can deal with the remaining water in the box in time.

[0022] Optionally, a sliding slope is provided on the sliding bar, and the distance between the sliding slope and the moisture-proof sponge gradually decreases in a vertical downward direction, and the sliding slope is located on the moving path of the moisture-proof sponge.

[0023] By adopting the above technical solution, the distance between the sliding slope and the moisture-proof sponge is gradually reduced in the vertical downward direction, so that the moisture-proof sponge pushes the sliding bar to move through the sliding slope, allowing the sliding bar to protrude from the box door, thereby achieving stable movement of the sliding bar.

[0024] Optionally, a sliding groove for inserting the sliding bar is formed on the fixed plate; when the sliding bar is inserted into the sliding groove, the fixing piece can abut against the stop bar; when the fixing piece does not abut against the stop bar, the sliding bar protrudes out of the box door in a direction away from the box body.

[0025] By adopting the above technical solution, the sliding bar is inserted into the sliding groove. At this time, the fixed plate is limited by the sliding bar, making it difficult for the fixed plate to move, further strengthening the degree of fixation of the fixed plate, and reducing the possibility of the fixing piece being detached from the first fixing groove or the second fixing groove due to shaking; when the fixing piece does not abut the stop bar, the fixed plate is not installed in place, so that the sliding groove is not in the insertion path of the sliding bar, and the sliding bar cannot be inserted into the fixed plate, so that the sliding bar protrudes out of the box door away from the box body. The staff can immediately know that the installation of the fixed plate is deviated and the fixed plate needs to be reinstalled.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Use elastic plates to seal the perforations, making it difficult for small animals to enter the placement slot directly through the perforations; the staff cuts the elastic plate, and the cable enters the placement slot through the elastic plate, allowing the elastic plate to abut the outer surface of the cable, so that the elastic plate can limit the distance between the cable and the perforation, thereby reducing the possibility of small animals crawling into the placement slot along the cable, and further reducing the damage caused by small animals to electrical components.

[0027] 2. The fixing piece is inserted into the first fixing groove, so that the fixing piece limits the stop bar and restricts the stop bar from abutting the cable, so that the staff can pass the cable through the through hole to install the cable; the staff moves the fixing plate to disengage the fixing piece from the second fixing groove. At this time, the stop bar is driven by the stop spring so that the stop bar can abut the cable, and then the staff moves the fixing plate to insert the fixing piece into the first fixing groove. The fixing piece limits the stop bar so that the stop bar can stably abut the cable, thereby greatly reducing the situation where small animals move the stop bar, so that the stop bar can more stably abut the cable.

[0030] The following is combined with Figure 1-6 This application is described in further detail.

[0031] Example 1 This embodiment discloses a cable branch box. Figure 1 and Figure 2A cable branch box comprises a box body 1 and a box door 2, wherein the box door 2 is rotatably connected to the box body 1. A placement slot 11 is provided on the box body 1, and the placement slot 11 is used to place power supply components.

[0032] Reference Figure 2 A through hole 12 for the cable to pass through is provided on the wall of the placement groove 11 close to the ground. The through holes 12 are provided with a plurality of holes, and a ring plate 121 is fixedly connected to the inside of the through hole 12. An elastic plate 13 is provided on the through hole 12, and the elastic plate 13 has elastic deformation capability. An elastic ring groove 131 is provided on the surface of the elastic plate 13, and the elastic ring groove 131 is inserted into the ring plate 121. When the elastic plate 13 is installed on the box body 1, the ring plate 121 is located in the elastic ring groove 131, so that the elastic plate 13 is installed at the through hole 12 in the box body 1.

[0033] The implementation principle of Example 1 is as follows: the worker cuts the elastic plate 13 to allow the cable to pass through the elastic plate 13 , and the elastic plate 13 can abut against the cable, thereby reducing the possibility of small animals crawling into the placement groove 11 along the cable.

[0034] Example 2 Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that the elastic plate 13 is fixedly connected to the hole wall of the through hole 12.

[0035] Reference Figure 5 Two grooves 14 are formed on the wall of the through hole 12, and the two grooves 14 are arranged opposite to each other along the axis of the through hole 12. A retaining spring 141 is provided in the groove 14, one end of the retaining spring 141 is fixedly connected to the bottom wall of the groove 14, and the other end of the retaining spring 141 is fixedly connected to a retaining strip 142.

[0036] Reference Figure 5 , the stop spring 141 can drive the stop bar 142 to move toward the direction close to the axis of the through hole 12. When the stop bar 142 abuts against the cable, the stop spring 141 is in a compressed state; when the stop bar 142 does not abut against the cable, the stop spring 141 is in a compressed state.

[0037] Reference Figure 5 A fixing plate 3 is provided on the placement plate, and a mounting hole 31 for the cable to pass through is provided on the fixing plate 3. Two fixing members 32 are slidably connected to the surface of the fixing plate 3, and the two fixing members 32 are arranged opposite to each other along the axis of the through hole 12. The fixing member 32 includes a fixing block 322 and a water-absorbing sponge 321, and the fixing block 322 is slidably connected to the fixing plate 3, and the fixing block 322 slides in the vertical direction. The water-absorbing sponge 321 is fixedly connected to the surface of the fixing block 322, and the water-absorbing sponge 321 extends in the vertical direction.

[0038] Reference Figure 5The surface of the stopper strip 142 is provided with a first fixing groove 143 and a second fixing groove 144. The first fixing groove 143 is located on the side of the second fixing groove 144 facing the stopper spring 141, and the first fixing groove 143 and the second fixing groove 144 are both for the water-absorbing sponge 321 to be inserted. The first fixing groove 143 penetrates the surface of the stopper strip 142, and the water-absorbing sponge 321 can pass through the first fixing groove 143, so that the water-absorbing sponge 321 can abut against the elastic plate 13.

[0039] Reference Figure 5 and Figure 6 A stop plate 145 is slidably connected to the surface of the stop bar 142, and a contact groove 146 is formed on the surface of the stop plate 145 facing the cable, and the contact groove 146 is for the cable to contact. A magnetic suction groove 147 is formed on the surface of the stop plate 145 facing the other stop plate 145, and a magnet 148 is fixedly connected in the magnetic suction groove 147. The magnet 148 on one stop plate 145 can attract the magnet 148 on the other stop plate 145, so that the two stop plates 145 are fixed to each other.

[0040] Reference Figure 5 When the two stop plates 145 abut against each other, the stop plate 145 can limit the movement of the cable. At this time, since the elastic plate 13 is cut, the stop plate 145 falls due to gravity, causing the elastic plate 13 to bend and deform toward the ground, so that the elastic plate 13 can limit the entry of small animals.

[0041] Reference Figure 5 A movable groove 15 is provided on the groove wall of the first fixed groove 143, and a moving bar 151 is slidably connected in the movable groove 15, and the moving bar 151 extends along the length direction of the stop bar 142. A moving inclined surface 152 is provided on the surface of the moving bar 151, and the distance between the moving inclined surface 152 and the fixed plate 3 gradually increases along the direction from the movable groove 15 to the first fixed groove 143, and the moving inclined surface 152 is located in the moving path of the fixing member 32 inserted into the first fixed groove 143. A movable groove 153 is provided on the surface of the stop plate 145 for the moving bar 151 to be inserted.

[0042] Reference Figure 5 When the fixing member 32 is inserted into the first fixing groove 143, the stop plate 145 falls due to gravity, so that the surface of the stop plate 145 away from the ground and the surface of the stop bar 142 away from the ground are coplanar, and the fixing member 32 drives the moving bar 151 to move through the moving inclined surface 152, and the moving bar 151 can be inserted into the moving groove 153, so that the moving bar 151 fixes the stop plate 145. If the moving bar 151 is not inserted into the moving groove 153, the staff needs to use tools or fingers to drive the stop plate 145 to move from the mounting hole 31, so that the moving groove 153 is located on the moving path of the moving bar 151.

[0043] Reference Figure 4 and Figure 5 , a plurality of rotating bars 4 are rotatably connected to the box body 1, and the plurality of rotating bars 4 are arranged in an array along the length direction of the box body 1. A moisture-proof sponge 41 is fixedly connected to the rotating bar 4, and the moisture-proof sponge 41 extends along the height direction of the box body 1, and the moisture-proof sponge 41 can absorb moisture. The moisture-proof sponge 41 is provided with moisture-proof holes 411, and the moisture-proof holes 411 are for cables to pass through. A plurality of moisture-proof blocks 42 are integrally formed on the surface of the moisture-proof sponge 41 facing the box door 2, and the fixed plate 3 is placed between two adjacent moisture-proof blocks 42. When the rotating bar 4 rotates, the moisture-proof sponge 41 is placed horizontally, and at this time the fixed plate 3 is located between two adjacent moisture-proof blocks 42.

[0044] Reference Figure 4 and Figure 5 The surface of the fixed block 322 is fixedly connected to the limit strip 16, which extends along the width direction of the box body 1 and can slide along the fixed block 322. The limit strip 16 is fixedly connected to the limit block 161, which extends along the height direction of the box body 1.

[0045] Reference Figure 4 and Figure 5 When the water-absorbing sponge 321 is inserted into the first fixing groove 143, the fixing member 32 and the limiting strip 16 are difficult to fall freely due to the friction of the fixing plate 3. At this time, the limiting strip 16 and the limiting block 161 are located on the rotation path of the rotating strip 4, making it difficult for the rotating strip 4 to rotate toward the door 2. If the water-absorbing sponge 321 absorbs enough water, the weight of the water-absorbing sponge 321 increases, so that the water-absorbing sponge 321 can drive the fixing member 32 and the limiting strip 16 to continue to fall. At this time, the limiting strip 16 and the limiting block 161 are not on the rotation path of the rotating strip 4, so that the moisture-proof sponge 41 can drive the rotating strip 4 to rotate, so that the moisture-proof sponge 41 covers the cable, and the fixing plate 3 is located between two adjacent moisture-proof blocks 42.

[0046] Reference Figure 4 , a receiving groove 43 is provided on the groove wall of the placement groove 11, and a dehumidification bag 431 is bonded in the receiving groove 43, and the dehumidification bag 431 can absorb moisture. When the rotating bar 4 does not rotate, the moisture-proof sponge 41 blocks the opening of the receiving groove 43, and the dehumidification bag 431 is difficult to absorb moisture in the placement groove 11. When the rotating bar 4 rotates, the moisture-proof sponge 41 does not block the opening of the receiving groove 43, and the dehumidification bag 431 can absorb moisture in the placement groove 11.

[0047] Reference Figure 4The door 2 is provided with a plurality of through holes 21, which are arranged in an array along the length direction of the door 2. A sliding ring groove 211 is provided on the hole wall of the through hole 21, and the sliding ring groove 211 extends along the length direction of the through hole 21. A sliding bar 22 is slidably connected in the through hole 21, and a sliding plate 221 is fixedly connected to the surface of the sliding bar 22. The sliding plate 221 moves in the sliding ring groove 211.

[0048] Reference Figure 4 , a plurality of sliding springs 222 are arranged in the sliding ring groove 211, and the plurality of sliding springs 222 are distributed in a circumferential array along the sliding ring groove 211. One end of the sliding spring 222 is fixedly connected to the sliding plate 221, and the other end of the sliding spring 222 is fixedly connected to the groove wall of the sliding ring groove 211. The sliding spring 222 drives the sliding bar 22 to move toward the bottom wall of the placement groove 11. When the sliding bar 22 does not protrude from the door 2 in the direction away from the bottom wall of the placement groove 11, the sliding spring 222 is in a non-stressed state; when the sliding bar 22 protrudes from the door 2 in the direction away from the bottom wall of the placement groove 11, the sliding spring 222 is in a compressed state.

[0049] Reference Figure 4 A sliding groove 33 is provided on the surface of the fixed plate 3, and the sliding groove 33 is inserted into the sliding bar 22. When the sliding bar 22 is inserted into the sliding groove 33, the sliding bar 22 limits the fixed plate 3 to restrict the movement of the fixed plate 3, and at this time, the sliding bar 22 does not protrude from the door 2 in the direction away from the bottom wall of the placement groove 11.

[0050] Reference Figure 4 The sliding bar 22 has a sliding slope 223 on its surface facing the box body 1, and the distance between the sliding slope 223 and the bottom wall of the placement groove 11 gradually decreases in the vertical downward direction. The sliding slope 223 is located on the rotation path of the moisture-proof block 42. When the moisture-proof sponge 41 rotates, the moisture-proof block 42 pushes the sliding bar 22 to move through the sliding slope 223, so that the sliding bar 22 protrudes from the box door 2 in a direction away from the bottom wall of the placement groove 11, so that the staff can observe whether the sliding bar 22 protrudes to determine whether there is water accumulation in the box body 1.

[0051] The implementation principle of Example 2 is as follows: the staff first cuts the elastic plate 13 and passes the cable through the elastic plate 13. Then the staff picks up the fixed plate 3, and then the water-absorbing sponge 321 disengages from the second fixed groove 144. At this time, the stop spring 141 drives the stop bar 142 to move, allowing the stop plate 145 to abut against the cable. The staff puts down the fixed plate 3 and inserts the water-absorbing sponge 321 into the first fixed groove 143. The water-absorbing sponge 321 drives the moving bar 151 to be inserted into the moving groove 153 through the moving inclined surface 152, so that the moving bar 151 limits the movement of the stop plate 145.
