Description

Technical Field

[0001] The invention relates to the technical field of cable connection, in particular to a cable installation junction box. Background Art

[0002] The junction box refers to a box used for cable wiring and collection of various equipment such as power transmission, distribution, control and protection in the power system. It is a very important component of the electrical system and has the function of protecting electrical equipment and maintaining the safety of electricians.

[0003] Some large-scale power facilities are usually set up in mountainous areas or near rivers according to local conditions. Due to the influence of geological structure, the area is usually accompanied by some small earthquakes. The junction box is the output port of the power facility, and its port connection will be affected by the vibration of the earthquake. Although the wiring port is a fixed connection, the continuous ground vibration will also cause gaps between the fixed connection ports, thereby affecting the power transmission efficiency. Over time, the wiring port will become loose or even cause the connection to fall off, which will affect the power transmission and thus affect the use of the entire power facility.

[0004] Therefore, those skilled in the art have proposed a cable installation junction box to solve the problems raised by the background technology. Summary of the invention

[0010] As a preferred solution of the cable installation junction box of the present invention, a locking rod is inserted into the inner wall of the through hole, and one end of the locking rod is sleeved on the locking cap.

[0011] As a preferred solution of the cable installation junction box of the present invention, a strip groove is opened on the outer wall of the top of the side plate near the joint of the first and second insertion strips, and a blocking piece is clamped on the inner wall of the strip groove near the top.

[0012] As a preferred solution of the cable installation junction box of the present invention, the buffer mechanism includes a damping cylinder, which is respectively installed on the outer wall of the bus duct and the terminal board on one side opposite to each other, a damping rod is movably inserted at one end of the damping cylinder, an annular plate is fixedly installed at one end of the damping rod, and spring coils are wrapped around the circumferential outer walls of the damping rod and the damping cylinder.

[0014] As a preferred solution of the cable installation junction box of the present invention, wherein: a hollow spring is sleeved on the circumferential outer wall of the cross bar, the hollow spring is located between the two air bags, one end of the two one-way valves extends to the interior of the hollow spring, a stop ball is fixed in the middle position of the hollow spring, the interior of the hollow spring is divided into two cavities by the stop ball, the interiors of the two cavities are filled with conductive paste, conductive particles are added to the conductive paste, and balls are slidably clamped in the hollow spring near the one-way valve.

[0015] As a preferred solution of the cable installation junction box of the present invention, thin tubes are inserted into the outer wall of the hollow spring near both sides of the blocking ball, and one end of the thin tube leads to the inside of the strip groove.

[0016] As a preferred solution of the cable installation junction box of the present invention, it also includes a box body, the bus duct and the terminal board are fixed on the bottom inner wall of the box body by bolts, foam strips are clamped on the inner walls on both sides of the box body, one side outer wall of the foam strip is attached to the outer wall on one side of the bus duct and the terminal board, a box cover is installed on the top outer wall of the box body, a plurality of mounting holes are opened on the outer wall on one side of the box body close to the terminal board, a wire fixing cylinder is clamped on the circumferential inner wall of the mounting hole, and a plurality of output ports are arranged on one end of the terminal board close to the wire fixing cylinder.

[0017] The beneficial effects of the cable installation junction box of the present invention are as follows: after the busbar strip 1 and the sub-line strip 2 are fitted and fixed, the two sides are clamped by side plates and fixed by locking rods and locking caps, so that the strip 1 and the strip 2 are tightly connected, which is sufficient for daily use. Because the device is used in large-scale power facilities in earthquake zones, there will be some ground vibrations during operation, and these vibrations will directly affect the connection of the junction box. After the junction box is affected by the ground vibration, it will vibrate itself, and the vibration will cause the hollow spring to compress and stretch. The movement of the hollow spring causes the air bags on both sides to expand and contract, so that gas is blown into the two sides of the hollow spring through the one-way valve, and the ball inside the hollow spring is pushed by the gas. When the ball moves, the conductive paste inside the hollow spring is squeezed toward the middle, so that the conductive paste moves in the capillary and then sprays into the strip groove, so that the conductive paste enters the connection between the strip 1 and the strip 2. Even in the case of ground vibration During the movement, a gap is generated between the fixedly connected plug-in strips 1 and 2, and the extruded conductive paste is also injected between the two to strengthen the connection between the plug-in strips 1 and 2. There are also conductive particles inside the conductive paste, which can ensure the connection between the plug-in strips 1 and 2 and ensure the stable transmission of electricity. While ensuring the transmission of electricity, a cross bar is arranged at the center of the hollow spring, and the hollow spring is located on the outside of the cross bar. The cross bar plays an auxiliary movement role, so that the hollow spring will not produce irregular shaking. The two sides of the cross bar are connected to the damping rod of the buffer mechanism. During the vibration process, the spring coil will be compressed, and then the damping rod is pressed into the damping cylinder. The elastic potential energy of the spring coil is converted into the energy of the damping force, and then dissipated into the atmosphere, which can make the elastic potential energy decay quickly, make the device quickly tend to stabilize, and reduce the influence of its own vibration on the junction box, thereby ensuring the power transmission of the junction box while reducing the influence of earthquake vibration on the junction box.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, reference Figures 1 to 7 , is the first embodiment of the present invention, which provides a cable installation junction box, including a busbar 100 and a terminal board 400, a plurality of busbar plug-ins 200 are installed on the outer wall of the busbar 100 close to the terminal board 400, a plurality of sub-line plug-ins 300 are installed on the outer wall of the terminal board 400 close to the busbar 100, one end of the sub-line plug-in 300 is in contact with one end of the corresponding busbar plug-in 200, and locking mechanisms 800 are provided on the outer walls of both sides of the busbar plug-in 200 and the sub-line plug-in 300. The locking mechanism 800 fixes the busbar plug-in 200 and the sub-line plug-in 300 in connection, and a plurality of buffer mechanisms 600 are arranged on the outer wall on the side opposite to the busbar trough 100 and the terminal board 400. The buffer mechanisms 600 are respectively located on both sides of the busbar plug-in 200 and the sub-line plug-in 300. The same ester adding mechanism 700 is installed at one end of the two buffer mechanisms 600 located on one side of the busbar plug-in 200 and the sub-line plug-in 300, and the output end of the ester adding mechanism 700 leads to the joint between the sub-line plug-in 300 and the busbar plug-in 200.

[0031] After the busbar plug-in 200 and the sub-line plug-in 300 are connected and fixed, the busbar plug-in 200 and the sub-line plug-in 300 are reinforced again on both sides by means of locking mechanisms 800 to reduce the possibility of loosening. Then, a buffer mechanism 600 and an ester adding mechanism 700 are arranged on both sides of the locking mechanism 800. The ester adding mechanism 700 vibrates itself when the ground vibrates, and then the conductive paste inside is sent into between the busbar plug-in 200 and the sub-line plug-in 300, thereby strengthening the connection between the busbar plug-in 200 and the sub-line plug-in 300 and ensuring smooth power transmission. Even if a gap is generated between the busbar plug-in 200 and the sub-line plug-in 300, the connection between the two can be strengthened.

[0032] Specifically, the busbar strip 200 includes a plug strip 201, which is installed on one side of the outer wall of the busbar trough 100, and a plurality of plug holes 202 are opened on one side of the outer wall of the plug strip 201. The sub-line strip 300 includes a plug strip 301, which is installed on one side of the outer wall of the terminal board 400, and a plurality of plug holes 302 are opened on one side of the outer wall of the plug strip 301.

[0033] The first plug-in strip 201 and the second plug-in strip 301 are connected and fixed, thereby ensuring the power transmission of the power system.

[0034] Specifically, the locking mechanism 800 includes two side panels 801, and the two side panels 801 are respectively arranged on both sides of the insertion strip 1 201, and the positions of the inner wall of one side of the side panel 801 corresponding to the insertion hole 1 202 and the insertion hole 2 302 are fixedly installed with a socket 806, and the socket 806 is clamped in the inside of the corresponding insertion hole 1 202 and the insertion hole 2 302, and the outer wall of one side of the side panel 801 is provided with a through hole 805 at a position corresponding to the center of the socket 806, and the through hole 805 is connected to the corresponding insertion hole 1 202 and the insertion hole 2 302.

[0035] Specifically, a locking rod 802 is inserted into the inner wall of the through hole 805 , and one end of the locking rod 802 is sleeved on the locking cap 803 .

[0036] Place the side plate 801 on both sides of the first and second insertion strips 201 and 301, then insert the locking rod 802 into the through hole 805, the first and second insertion strips 202 and 302, and then lock and fix them with the locking cap 803, thereby strengthening the connection between the first and second insertion strips 201 and 301.

[0037] Furthermore, a strip groove 807 is formed on the top outer wall of the side plate 801 near the joint of the first inserting strip 201 and the second inserting strip 301 , and a blocking piece 804 is clamped on the inner wall of the strip groove 807 near the top.

[0038] The strip groove 807 is closed by the baffle 804, and the baffle 804 is opened regularly to clean foreign matter inside.

[0039] Example 2, reference Figure 4 , Figure 5 and Figure 7 , which is the second embodiment of the present invention. Different from the previous embodiment, the buffer mechanism 600 includes a damping cylinder 601, which is respectively installed on the outer wall of the bus duct 100 and the terminal board 400 on the opposite side. A damping rod 602 is movably inserted at one end of the damping cylinder 601, and an annular plate 604 is fixedly installed at one end of the damping rod 602. Spring coils 603 are wound around the circumferential outer walls of the damping rod 602 and the damping cylinder 601.

[0040] During the vibration process, the spring coil 603 will be compressed, and then the damping rod 602 will be pressed into the damping cylinder 601. The elastic potential energy of the spring coil 603 will be converted into the energy of the damping force, and then dissipated into the atmosphere, which can quickly decay the elastic potential energy, allowing the device to quickly stabilize and reduce the impact of its own vibration on the junction box.

[0041] Preferably, the esterification mechanism 700 includes a cross bar 605, both ends of which are fixedly connected to the damping rod 602, and both ends of the cross bar 605 are sleeved with air bags 701, and the opposite ends of the two air bags 701 are installed with rings 702, and a one-way valve 705 is arranged inside the ring 702, and the one-way valve 705 is installed at the air outlet end of the air bag 701.

[0042] Specifically, a hollow spring 703 is sleeved on the circumferential outer wall of the cross bar 605, and the hollow spring 703 is located between the two air bags 701. One ends of the two one-way valves 705 extend into the interior of the hollow spring 703. A blocking ball 707 is fixed in the middle of the hollow spring 703. The interior of the hollow spring 703 is divided into two cavities by the blocking ball 707. The interiors of the two cavities are filled with conductive paste, and conductive particles are added to the conductive paste. Ball bearings 706 are slidably clamped in the hollow spring 703 near the one-way valve 705.

[0043] Among them, thin tubes 704 are inserted into the outer wall of the hollow spring 703 near the two sides of the blocking ball 707, and one end of the thin tube 704 leads to the inside of the strip groove 807.

[0044] There will be some ground vibrations during operation, which will directly affect the connection of the junction box. After being affected by the ground vibration, the junction box will vibrate itself, which will compress and stretch the hollow spring 703. The movement of the hollow spring 703 causes the air bags 701 on both sides to expand and contract, thereby blowing gas into both sides of the hollow spring 703 through the one-way valve 705, and the gas pushes the ball 706 inside the hollow spring 703. When the ball 706 moves, it squeezes the conductive paste inside the hollow spring 703 toward the middle. The conductive paste moves in the capillary 704 and then sprays into the strip groove 807, so that the conductive paste enters the connection between the first plug 201 and the second plug 301. Even if a gap is generated between the first plug 201 and the second plug 301 that are fixedly connected during ground vibration, the extruded conductive paste will be injected between the two to strengthen the connection between the first plug 201 and the second plug 301. There are also conductive particles in the conductive paste, which can ensure the connection between the first plug 201 and the second plug 301 and ensure the stable transmission of electricity.

[0045] Example 3, reference Figure 1 and Figure 2, which is the third embodiment of the present invention. Different from the previous embodiment, it also includes a box body 500, and the bus duct 100 and the terminal board 400 are fixed on the bottom inner wall of the box body 500 by bolts. Foam strips 502 are clamped on the inner walls on both sides of the box body 500, and one side outer wall of the foam strip 502 is attached to the outer wall on one side of the bus duct 100 and the terminal board 400. A box cover 503 is installed on the top outer wall of the box body 500, and a plurality of mounting holes are opened on the outer wall on one side of the box body 500 close to the terminal board 400, and a wire fixing cylinder 501 is clamped on the circumferential inner wall of the mounting hole, and a plurality of output ports are arranged on one end of the terminal board 400 close to the wire fixing cylinder 501.

[0046] The bus duct 100 and the terminal board 400 are both placed in a box body 500 , and the foam strips 502 inside the box body 500 provide protection.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
