[0061] Compared with the prior art, the present invention has the following beneficial effects:

[0062] (1) The box cover is driven to flip on the outer box through the rotational movement of the driving mechanism. The opening and closing of the box cover corresponds to the opposite or opposite movement of the two symmetrical wiring mechanisms. When the two wiring mechanisms move towards each other, the box cover is closed, and when the two wiring mechanisms move in the opposite direction, the box cover is opened. Therefore, the box cover is powered only when it is closed, and the power is automatically cut off when the box cover is opened, which can effectively ensure the safety of power connection and the personal safety of the staff;

[0063] (2) The movement of the wire pressing assembly can be limited and driven by the deformation of the spring buckle, elastic reset and drive of the coil spring, so that the cable can be quickly fixed, thereby improving the connection efficiency of the installed cable. At the same time, the connection between the cable core and the wire connecting piece is completed in the inner cavity of the junction box. The box body and the junction box form a two-layer sealing structure, which can effectively reduce the dust and impurities in the external air from entering between the cable core and the wire connecting piece, thereby reducing the influence of dust and impurities on the power connection;

[0064] (3) When the pressure plate is pressed on the wire core to fix the wire core, the pressure rod moves toward the inner cavity of the junction box under the action of external force, and the pressure rod drives the limit ring to move downward to compress the spring. The pressure rod presses on the buckle tongue to apply downward force to the buckle tongue, so that the pressure plate can be firmly pressed on the wire core, avoiding the phenomenon that the cable core is easy to fall off due to insufficient downward pressure of the pressure plate, thereby ensuring the stability of the connection between the cable core and the wire connecting piece;

[0065] (4) After closing the cover, the cover body presses against the pressure rod to drive the pressure rod down to the buckle tongue, thereby firmly pressing the pressure plate on the wire core, which can prevent the wire core from falling off and ensure the stability of power transmission. After opening the cover, the cover body moves away from the pressure rod to release the pressure on the pressure rod. The pressure rod is reset under the drive of the spring, releasing the pressure on the buckle tongue, making it easier to remove the cable;

[0066] (5) The two sides of the cover body are closed on the box body through the second connecting rod, thereby reducing the gap between the cover body and the box body and ensuring the sealing effect of the inner cavity of the box body. This can effectively prevent dust and impurities in the external air from entering the inner cavity of the box body and reduce the impact of dust and impurities on power transmission.

DETAILED DESCRIPTION

[0078] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0079] The present invention provides a flexible cable connection device with a sealing structure. The driving mechanism interlocks the wiring mechanism and the box cover. The power can be turned on only after the box cover is closed, and the power is turned off after the box cover is opened. The safety of the power connection can be effectively guaranteed, and the personal safety of the staff can be guaranteed. Figure 1 , including: an outer box 100, a driving mechanism 200, a wiring mechanism 300 and a box cover 400;

[0080] Example 1

[0081] See also Figure 1The driving mechanism 200 is movably installed in the inner cavity of the outer box 100, and part of the structure of the driving mechanism 200 is arranged outside the outer box 100. The driving mechanism 200 can be manually operated by a staff member so that the driving mechanism 200 rotates in the inner cavity of the outer box 100 to generate rotational power;

[0082] There are two groups of wiring mechanisms 300, which are symmetrically installed in the inner cavity of the outer box 100. The end of the cable penetrates the outer box 100 and is inserted into the inner cavity of the outer box 100 to connect with the wiring mechanisms 300. The two wiring mechanisms 300 are both connected to the driving mechanism 200. The rotational power generated by the driving mechanism 200 drives the wiring mechanisms 300 to move horizontally in the inner cavity of the outer box 100, so that the two wiring mechanisms 300 move towards or in opposite directions. After the two wiring mechanisms 300 move towards each other, they will fit together for power transmission. After the two wiring mechanisms 300 move in opposite directions, the two wiring mechanisms 300 will move away from each other to cut off power transmission.

[0083] The box cover 400 is movably connected to the outer box 100 and connected to the driving mechanism 200. The box cover 400 is driven to flip on the outer box 100 through the rotational movement of the driving mechanism 200. The opening and closing of the box cover 400 corresponds to the opposite or opposite movements of the two symmetrical wiring mechanisms 300. When the two wiring mechanisms 300 move towards each other, the box cover 400 is closed, and when the two wiring mechanisms 300 move in the opposite direction, the box cover 400 is opened. Therefore, the box cover 400 is powered on only when it is closed, and the power is automatically cut off when the box cover 400 is opened, which can effectively ensure the safety of the power connection and the personal safety of the staff.

The buckle tongue 340b is inserted into the inner side of the buckle groove 330b and contacts the arc buckle block 330c. The arc buckle block 330c and the buckle tongue 340b cooperate to limit the rotation of the second mounting seat 340a.

[0107] The pressing plate 340c is integrally formed at the bottom of the buckle tongue 340b, and one end of the pressing plate 340c away from the buckle tongue 340b contacts the side of the arc-shaped buckle block 330c that is long and faces the second mounting seat 340a;

[0108] The touch plate 330d is integrally formed on the side of the circumferential outer wall of the second mounting seat 340a away from the second mounting plate 330a. The touch plate 330d passes through the top of the junction box 320 facing the first wire hole 110a and is arranged on the outside of the junction box 320. By manually pressing the touch plate 330d, the elastic force of the coil spring can be overcome to drive the second mounting seat 340a to rotate in the opposite direction.

[0109] In specific use, the cable passes through the first wire hole 110a, and the wire core on the cable passes through the second wire hole 320b and is plugged into the inner cavity of the junction box 320 to contact the touch plate 330d. At the same time, an external force is manually applied to the cable to drive the touch plate 330d and the vertical plate on the second mounting plate 330a to deform through the cable wire core, thereby releasing the restriction on the second mounting seat 340a. The second mounting seat 340a drives the pressing plate 340c to rotate toward the bottom of the inner cavity of the junction box 320 under the elastic force of the coil spring, so that the pressing plate 340c rotates toward the bottom of the inner cavity of the junction box 320. 0c is pressed on the wire core to fix the wire core in the inner cavity of the junction box 320. At this time, the end of the buckle tongue 340b away from the second mounting seat 340a presses on the arc buckle block 330c to prevent the touch plate 330d and the vertical plate on the second mounting plate 330a from resetting. When it is necessary to release the fixation of the wire core, it is only necessary to manually press the pressing block 340d to overcome the elastic force of the coil spring to drive the second mounting seat 340a to rotate in the opposite direction, release the fixation of the wire core, and pull the wire core out of the junction box 320. The second mounting seat 340a rotates in the opposite direction. When the buckle tongue 340b moves to the position corresponding to the buckle groove 330b, the buckle tongue 340b releases the reset restriction on the touch plate 330d and the vertical plate on the second mounting plate 330a. The touch plate 330d and the vertical plate on the second mounting plate 330a are reset under the action of their own elastic force. The buckle tongue 340b is re-inserted into the inner side of the buckle groove 330b to limit the second mounting seat 340a. The deformation, elastic reset and coil spring drive can limit and drive the movement of the wire pressing assembly 340, and can quickly fix the cable, thereby improving the connection efficiency of the installed cable. At the same time, the connection between the cable core and the wire connecting piece 350a is completed in the inner cavity of the junction box 320. The box body 110 and the junction box 320 form a two-layer sealing structure, which can effectively reduce the dust and impurities in the external air from entering between the cable core and the wire connecting piece 350a, thereby reducing the influence of dust and impurities on the power connection.

[0110] The conductive sheet 350 is installed in the inner cavity of the junction box 320 and contacts the cable core. The conductive sheet 350 is made of conductive material. The conductive sheet 350 is composed of a wire connecting sheet 350a, a first connecting block 350b and a fixing block 350c.

[0111] The wire connecting piece 350a is arranged at the bottom of the inner cavity of the junction box 320. The cable core is inserted into the inner cavity of the junction box 320 through the second wire hole 320b and contacts the touch plate 330d, driving the touch plate 330d and the vertical plate on the second mounting plate 330a to deform and release the limit of the second mounting seat 340a. The second mounting seat 340a drives the pressing plate 340c to press down under the drive of the coil spring. The pressing plate 340c contacts the cable core and fixes the cable core on the top of the wire connecting piece 350a.

[0112] The first connection block 350b is integrally formed on the end of the wire connection sheet 350a away from the second wire hole 320b, and the first connection block 350b penetrates the end of the junction box 320 away from the second wire hole 320b and is arranged on the outside of the junction box 320. The junction boxes 320 distributed on the left and right sides of the inner cavity of the box 110 are driven by the first auxiliary drive shaft 230 and the second auxiliary drive shaft 250 until the first connection blocks 350b on the junction boxes 320 distributed on the left and right sides of the inner cavity of the box 110 are attached together to transmit power;

[0113] The fixing block 350c is integrally formed obliquely on one end of the first connection block 350b away from the wire connection piece 350a. The fixing block 350c contacts the inner cavity slope of the junction box 320 to fix the wire connection piece 350a and the first connection block 350b in the inner cavity of the junction box 320.

[0114] Example 3

[0115] See also Figure 1-5 , Figure 7 and Figure 9-10 The pressure rod assembly 360 is composed of a pressure rod 360a, a spring 360b, a limiting ring 360c and a fixing ring 360d;

[0116] The pressure rod 360a is coaxially arranged in the inner cavity of the guide hole 320c, one end of the pressure rod 360a passes through the guide hole 320c and is arranged outside the junction box 320, and the other end of the pressure rod 360a passes through the guide hole 320c and is arranged in the inner cavity of the junction box 320 and contacts the top surface of the buckle tongue 340b;

[0117] The spring 360b is sleeved on the outer circumferential wall of the pressure rod 360a and inserted into the inner cavity of the guide hole 320c, and the bottom end of the spring 360b contacts the bottom of the inner cavity of the guide hole 320c;

[0118] The limiting ring 360c is coaxially welded to the outer circumferential wall of the pressure rod 360a, the limiting ring 360c is inserted into the top of the inner cavity of the guide hole 320c and contacts the top of the spring 360b, and the limiting ring 360c is movably connected to the guide hole 320c through a linear bearing;

[0119] The fixing ring 360d is sleeved on the outer circumferential wall of the pressure rod 360a. The fixing ring 360d is detachably mounted on the top of the junction box 320 by bolts. The pressure rod 360a can move along the axial direction of the fixing ring 360d on the inner side of the fixing ring 360d.

[0120] Specifically, when the pressing plate 340c is pressed on the wire core to fix the wire core, the pressing rod 360a moves toward the inner cavity of the junction box 320 under the action of external force, and the pressing rod 360a drives the limiting ring 360c to move downward to compress the spring 360b. The pressing rod 360a presses on the buckle tongue 340b to apply a downward force to the buckle tongue 340b, so that the pressing plate 340c can be firmly pressed on the wire core, avoiding the phenomenon that the cable core is easy to fall off due to insufficient downward pressure of the pressing plate 340c, thereby ensuring the stability of the connection between the cable core and the wire connecting piece 350a.

[0121] There are two box covers 400, which are symmetrically installed at the top opening of the box body 110. The box cover 400 is composed of a cover body 410, a first fixing ear 420, a driving ring 430, a first connecting rod 440, a third fixing ear 450, a guide ring 460 and a second connecting rod 470.

[0122] The cover 410 is movably installed at the top opening of the box 110 through a pin shaft. The cover 410 can be turned over at the top of the box 110 through the pin shaft. The inside of the box 110 can be sealed and operated by opening and closing the cover 410. When the cover 410 is closed on the box 110, the cover 410 and the box 110 are sealed by a sealing strip.

[0123] The first fixing ear 420 is detachably mounted on the cover body 410 at the middle position of the side facing the box body 110 by bolts, and the second connecting block 420a is mounted on the inner side of the first fixing ear 420 by a pin shaft, and the end of the second connecting block 420a away from the cover body 410 is arranged on the outer side of the first fixing ear 420, and the second connecting block 420a can be turned over on the first fixing ear 420 by a pin shaft;

[0124] The inner cavity of the driving ring 430 is provided with a second inner thread 430b, and the second inner thread 430b matches the first outer thread 210a or the second outer thread 210b. The driving ring 430 is installed on the outer circumferential wall of the main driving shaft 210 through threaded connection. The two driving rings 430 symmetrically installed on the main driving shaft 210 move toward or in opposite directions through the rotation of the main driving shaft 210.

[0125] A second fixing ear 430a is integrally formed on the top of the driving ring 430. The second fixing ear 430a corresponds to the first fixing ear 420. A third connecting block 430c is installed on the inner side of the second fixing ear 430a via a pin. One end of the third connecting block 430c away from the driving ring 430 is arranged on the outer side of the second fixing ear 430a. The third connecting block 430c can be turned over on the second fixing ear 430a via a pin.

[0126] One end of the first connecting rod 440 is detachably connected to the second connecting block 420a by a bolt, and the other end of the first connecting rod 440 is detachably connected to the third connecting block 430c by a bolt;

[0127] Specifically, the main drive shaft 210 is manually driven to rotate, and the two drive rings 430 installed on the main drive shaft 210 move toward each other, and the second fixing ear 430a is driven to move by the drive ring 430, and the third connecting block 430c is driven to move by the second fixing ear 430a, and the third connecting block 430c pulls the first connecting rod 440 to move obliquely downward, and the third connecting block 430c is turned over on the second fixing ear 430a through the pin shaft, and the second connecting block 420a is turned over on the first fixing ear 420, so that the first connecting rod 440 gradually approaches the main drive shaft 210, thereby pulling the cover body 410 to cover the box body 110 to complete the cover closing operation. At the same time, the rotation of the main drive shaft 210 drives the junction boxes 320 distributed on both sides of the inner cavity of the box body 110 to gradually approach until the first connecting blocks 350b are attached together to complete the power transmission operation;

[0128] The main drive shaft 210 is manually rotated in the opposite direction, and the two drive rings 430 installed on the main drive shaft 210 make opposite movements, and the second fixing ear 430a is driven to move by the drive ring 430, and the third connecting block 430c is driven to move by the second fixing ear 430a, and the third connecting block 430c pushes the first connecting rod 440 to move obliquely upward, and the third connecting block 430c is turned over on the second fixing ear 430a through the pin shaft, and the second connecting block 420a is turned over on the first fixing ear 420, so that the first connecting rod 440 gradually moves away from the main drive shaft 210, thereby pushing the cover body 410 away from the box body 110 to complete the cover opening operation. While opening the cover, the rotation of the main drive shaft 210 drives the junction boxes 320 distributed on both sides of the inner cavity of the box body 110 to gradually move away to achieve the effect of power off;

[0129] It can power on when the cover is closed and power off when the cover is opened, which can effectively ensure the safety of power connection and the personal safety of workers;

[0130] At the same time, after closing the cover, the cover body 410 presses against the pressure rod 360a to drive the pressure rod 360a to press down onto the buckle tongue 340b, thereby firmly pressing the pressure plate 340c on the wire core, which can prevent the wire core from falling off and ensure the stability of power transmission. After opening the cover, the cover body 410 moves away from the pressure rod 360a to release the pressure on the pressure rod 360a. The pressure rod 360a is reset under the drive of the spring 360b, and the pressure on the buckle tongue 340b is released, which is convenient for disassembly of the cable.

[0131] There are two third fixing ears 450, which are detachably mounted on the cover body 410 at the middle position of the side facing the box body 110 by bolts, and the two third fixing ears 450 are distributed on both sides of the first fixing ear 420 and correspond to the guide rod 130. A fourth connecting block 450a is mounted on the inner side of the third fixing ear 450 by a pin shaft, and an end of the fourth connecting block 450a away from the cover body 410 is arranged on the outer side of the third fixing ear 450, and the fourth connecting block 450a can be turned over on the third fixing ear 450 by a pin shaft;

[0132] The guide ring 460 is installed on the outer circumferential wall of the guide rod 130 through a linear bearing. The guide ring 460 can move along the axial direction of the guide rod 130 on the outer circumferential wall of the guide rod 130 through the linear bearing. A fourth fixing ear 460a is integrally formed on the top of the guide ring 460. A fifth connecting block 460b is installed on the inner side of the fourth fixing ear 460a through a pin shaft. An end of the fifth connecting block 460b away from the guide ring 460 is arranged on the outer side of the fourth fixing ear 460a. The fifth connecting block 460b can be turned over on the fourth fixing ear 460a through a pin shaft.

[0133] One end of the second connecting rod 470 is detachably connected to the fourth connecting block 450a by a bolt, and the other end of the second connecting rod 470 is detachably connected to the fifth connecting block 460b by a bolt;

[0134] Specifically, when closing the cover, the cover body 410 pushes the third fixing ear 450 to move downward, and the third fixing ear 450 drives the fourth connecting block 450a to move downward. At the same time, the fourth connecting block 450a flips on the third fixing ear 450 through the pin shaft, and the fourth connecting block 450a pushes the second connecting rod 470 to move downward and gradually approach the guide rod 130. The second connecting rod 470 pushes the fifth connecting block 460b to flip on the fourth fixing ear 460a. At the same time, the fifth connecting block 460b pushes the guide ring 460 to move horizontally on the guide rod 130 through the fourth fixing ear 460a. The two guide rings 460 on the guide rod 130 gradually approach each other, and the two sides of the cover body 410 are closed on the box body 110 through the second connecting rod 470, so as to reduce the gap between the cover body 410 and the box body 110, thereby ensuring the sealing effect of the inner cavity of the box body 110, and effectively preventing dust and impurities in the external air from entering the inner cavity of the box body 110, thereby reducing the influence of dust and impurities on power transmission.

[0135] Example 4

[0136] The control system includes:

[0137] The acquisition module is composed of a dust concentration sensor, a humidity sensor and an infrared temperature sensor. The dust concentration sensor and the humidity sensor are installed in the inner cavity of the box 110 to collect dust concentration and humidity data in the inner cavity of the box 110. The infrared temperature sensor is installed in the inner cavity of the junction box 320 to collect temperature data in the inner cavity of the junction box 320.

[0138] A conversion module, which is electrically connected to the acquisition module and is used to perform analog-to-digital conversion on the acquired data;

[0139] A storage module, the storage module is used to execute and store set parameter data;

[0140] A processing module, the processing module is electrically connected to the conversion module and the storage module respectively, and is used to compare the collected data with the stored data and output the comparison result;

[0141] A control module, which is electrically connected to the processing module and is used to receive the comparison result output by the processing module and output a control signal according to the comparison result. The control module is embedded with a communication module for executing a remote alarm;

[0142] The control system includes the following specific operation steps:

[0143] The dust concentration data is set as d0 and the humidity data is set as h0 through the storage module, the dust concentration data collected by the dust concentration sensor is set as d1, and the humidity data collected by the humidity sensor is set as h1;

[0144] When d1<d0 and h1<h0, it means that the dust concentration and humidity in the inner cavity of the box body 110 are relatively low at this time, and the dust and humidity will not affect the transmission of power, so no operation is performed;

[0145] When d0<d1<1.23×d0 and h1<h0, it means that there is a certain amount of dust in the box 110 at this time, and the humidity in the inner cavity of the box 110 is low. The low humidity cannot affect the dust, that is, the dust cannot gather into a ball at this humidity, resulting in a smaller dust particle size and easy to float at low humidity. When the current passes through, the dust is easily adsorbed on the first connecting block 350b, but the dust concentration in the inner cavity of the box 110 is low and will not affect the power transmission. At this time, the control module controls the communication module to send dust concentration data and humidity data to the staff, and only needs to send 1-2 times a month;

[0146] When 1.23×d0<d1<1.78×d0 and h1<h0, it means that there is a lot of dust in the inner cavity of the box 110 and the humidity is low and it cannot gather into a ball. It is very easy to be adsorbed to the first connecting block 350b, which is likely to affect the transmission of power. At this time, the module box staff sends an alarm message. After receiving the alarm message, the staff needs to clean the inside of the box 110 within 1-2 weeks to ensure the normal transmission of power.

[0147] When 1.78×d0<d1<2.30×d0 and h1<h0, it means that there is a lot of dust in the inner cavity of the box 110 and the humidity is low and it cannot gather into a ball. It is very easy to be adsorbed on the first connecting block 350b and will definitely affect the transmission of electricity. At this time, an alarm is issued through the communication module. After receiving the alarm information, the staff needs to deal with the dust in the inner cavity of the box 110 within 1-2 working days;

[0148] When d0<d1<1.23×d0 and h0

[0149] When 1.23×d0<d1<1.78×d0 and h0

[0150] ​​When 1.78×d0<d1<2.30×d0 and h0

[0151] When h1>3.2×h0, it means that the humidity in the inner cavity of the box 110 is extremely high at this time, and the extremely high humidity can easily affect the transmission of electricity. Therefore, at this time, no matter what the concentration in the inner cavity of the box 110 is, the humidity in the inner cavity of the box 110 needs to be adjusted. At this time, the control module controls the communication module to alarm the staff. After receiving the alarm signal, the staff needs to rush to the site within 3-6 hours to cut off the power and adjust the humidity in the inner cavity of the box 110;

[0152] The temperature data is set as t0 through the storage module, and the temperature data of the inner cavity of the junction box 320 collected by the temperature sensor is t1;

[0153] When t0<t1<1.36×t0, it indicates that the temperature of the inner cavity of the junction box 320 is in a normal state, and the work continues without any operation;

[0154] When 1.36×t0<t1<2.3×t0, it indicates that the temperature of the inner cavity of the junction box 320 is relatively high. It is possible that the wire core has been rubbing against the wire connecting piece 350a for a long time, causing the surface of the wire connecting piece 350a to be uneven. The uneven surface of the wire connecting piece 350a will increase the resistance of the wire connecting piece 350a, thereby causing the temperature of the inner cavity of the junction box 320 to rise. At this time, the temperature data is sent to the staff through the communication module. The temperature data is sent once a day. If the temperature of the inner cavity of the junction box 320 is always maintained in the range of 1.36×t0<t1<2.3×t0 for 1-2 consecutive months, the staff needs to replace the conductive sheet 350 within 1-2 working days. If the temperature data received is maintained in the range of 1.36×t0<t1<2.3×t0 for only 2-3 weeks within 1-2 months, no operation is performed.

[0155] ​When t1>2.3×t0, the temperature rise indicates that the wire connecting plate 350a is severely damaged. At this time, the temperature data is sent to the staff as in the previous step. If the temperature of the inner cavity of the junction box 320 is always maintained in the range of t1>2.3×t0 for 1-2 consecutive months, the staff needs to replace the conductive plate 350 within 3-6 hours. If the received temperature data is maintained in the range of t1>2.3×t0 for only 2-3 weeks within 1-2 months, no operation is performed.
