It is a mature technical means in the prior art. This solution only borrows its function of being able to adjust the length according to actual needs and maintain the changed length after the length is changed. Its structure and working principle will not be elaborated here.

[0026] The specific length and model of the two clip telescopic rods 6 can be selected according to the specific position and height to be fixed without affecting the operation of the fixing assembly 3;

[0027] The components of the four fixing components 3 are the same, the structures of the wrapping shell 1 and the wrapping shell 2 are the same, the front ends of the wrapping shell 1 and the wrapping shell 2 are connected by two chain plates, and the two fixing components 3 arranged in the wrapping shell 1 and the two fixing components 3 arranged in the wrapping shell 2 are symmetrically distributed up and down;

[0028] In a specific implementation, the buckle assembly 5 is opened so that the wrapping shell 1 and the wrapping shell 2 are no longer fixed together, and then the wrapping shell 1 is opened, and the rectangular busbar connector is placed in the rectangular groove in the middle of the inner surface of the wrapping shell 2, and the busbars to be connected are plugged into the left and right side sockets of the rectangular busbar, and the plugged left and right side busbars are respectively placed in the two fixing assemblies 3 set in the wrapping shell 2;

[0029] Then, the wrapping shell 1 is rotated so that the wrapping shell 1 covers the wrapping shell 2. At this time, the wrapping shell 1 and the wrapping shell 2 wrap the rectangular busbar joint, thereby forming protection for the rectangular busbar joint.

[0030] The two rectangular rubber pads 4 can play a buffering role to prevent the wrapping of the wrapping shell 1 and the wrapping shell 2 from causing damage to the rectangular busbar joint, and at the same time play an insulating role to prevent the rectangular busbar structure connected to the busbar from leaking electricity due to reasons such as aging of the busbar or poor contact, thereby causing damage to the staff;

[0031] After the wrapping shell 1 and the wrapping shell 2 wrap the rectangular busbar structure, the busbars on the left and right sides are respectively located between the upper and lower fixing components 3 on the same side. The four fixing components 3 are rotated so that the upper and lower fixing components 3 on the same side clamp and fix the busbars on the left and right sides respectively, and then the wrapping shell 1 and the wrapping shell 2 2 are fixed together using the buckle component 5;

[0032] Then, according to the specific use position of the rectangular busbar connector, the two snap-on telescopic rods 6 are adjusted to a suitable length, and then the mounting plate 7 is fixed at this position with bolts, thereby ensuring the stable operation and safety of the power system.

[0033] Specifically, in order to effectively protect the rectangular busbar joint and prevent the rectangular busbar joint from being directly exposed to the external environment and thus causing damage, refer to Figure 4 The fixing assembly 3 includes a rotating handle 31, the upper end of which is fixedly connected to a threaded rod 34, the upper end of which passes through the middle of the left side of the lower end of the wrapped shell 22 and extends into the wrapped shell 22, the upper end of the threaded rod 34 is rotatably connected to an arc-shaped clamping plate 36, and the lower end of the arc-shaped clamping plate 36 is symmetrically fixedly connected to telescopic rods 35 on the left and right sides, and the two telescopic rods 35 are both fixedly connected to the lower left part of the inner surface of the wrapped shell 22, and an arc-shaped rubber pad 37 is fixedly connected to the inner surface of the upper side of the arc-shaped clamping plate 36, and a shielding assembly 38 is arranged on the left side of the arc-shaped clamping plate 36; the outer surface of the rotating handle 31 is fixedly connected to a rubber jacket 32, and the outer surface of the rubber jacket 32 ​​is fixedly connected to a plurality of rubber blocks 33, and the plurality of rubber blocks 33 are distributed in an arc-shaped array;

[0034] The shielding assembly 38 includes a shielding plate 1 381, which is fixedly connected to the lower left portion of the inner surface of the wrapping shell 2 2, and a shielding plate 2 382 is slidably connected to the inner surface of the shielding plate 1 381, and the shielding plate 2 382 is fixedly connected to the left end of the arc-shaped clamping plate 36.

[0035] In a specific implementation, the buckle assembly 5 is opened so that the package shell 1 and the package shell 2 are no longer fixed together, and then the package shell 1 is opened, and the rectangular busbar connector is placed in the rectangular groove in the middle of the inner surface of the package shell 2. At this time, the busbar sockets on both sides of the rectangular busbar connector are respectively opposite to the left and right fixing assemblies 3;

[0036] Then, the busbars to be connected are plugged into the left and right sockets of the rectangular busbars, and the busbars on the left and right sides are straightened and put together on the left and right arc-shaped clamping plates 36 provided in the second wrapping shell 2, and then the wrapping shell 1 is rotated to cover the wrapping shell 2, thereby wrapping the rectangular busbar joint;

[0037] At this time, the busbars on the left and right sides are located between the upper and lower arc-shaped clamping plates 36 on the same side, and then the two rotating handles 31 symmetrically distributed on the same side are rotated clockwise, thereby driving the two threaded rods 34 to rotate, thereby driving the two arc-shaped clamping plates 36 to move closer to each other until the busbar between the two is fixed firmly, thereby maintaining the stability of the busbar plugged into the rectangular busbar structure and the operation of the busbar structure, thereby maintaining the normal operation of the power system;

[0038] Repeat the above operation so that the two arc-shaped clamping plates 36 on the other side can also complete the fixing work of the busbar on the other side;

[0039] The two telescopic rods 35 provided in each fixing assembly 3 are used to limit the movement of the arc-shaped clamping plate 36;

[0040] The arc-shaped rubber pad 37 can play a buffering role to prevent the damage of the busbar caused by the clamping and fixing of the two arc-shaped clamping plates 36 on the same side, and at the same time play an insulating role to prevent the busbar from leaking electricity due to aging or poor contact of the busbar, thereby transmitting it to the threaded rod 34 and causing electric shock injuries to the staff;

[0041] The rubber jacket 32 ​​and the rubber block 33 can increase the friction force, making the process of turning the rotating handle 31 more comfortable, and also play an insulating role, preventing the busbar leakage from being transmitted to the threaded rod 34, so that the staff will be electrically shocked when turning the rotating handle 31, causing injuries;

[0042] When the four arc-shaped clamping plates 36 move up and down, they can respectively drive the four shielding plates 382 to move up and down inside the shielding plate 1 381, so as to cover the openings on both sides of the wrapping shell 1 and the wrapping shell 2 after they are covered, to prevent the openings from being too large, and dust and other impurities in the external environment from easily entering the wrapping shell 1 and the wrapping shell 2 from the openings, causing damage to the rectangular busbar joints wrapped in the wrapping shell 1 and the wrapping shell 2.

[0043] Specifically, in order to prevent the wrapping shell 1 from being easily opened after the wrapping shell 1 is covered and the wrapping shell 2 wraps the rectangular busbar connector, refer to Figure 5The buckle assembly 5 includes a slot assembly 51, and a rod assembly 52 is arranged on the lower side of the slot assembly 51; the slot assembly 51 includes two fixed blocks 511 and two slide rails 515, and the two slide rails 515 are fixedly connected to the middle part of the rear end of the package shell 1, and the two fixed blocks 511 are slidably connected to the two slide rails 515 respectively, and the two fixed blocks 511 are fixedly connected to a round rod 512 at one opposite end, and a plug plate 513 is rotatably connected to the outer surface of the round rod 512, and a slot 514 is provided at the lower right end of the plug plate 513; the rod assembly 52 includes a mounting shell 521, and the mounting shell 521 is fixedly connected to the upper side of the middle part of the rear end of the package shell 2, and a spring 524 is fixedly connected to the right side of the inner surface of the mounting shell 521, and a pull plate 523 is fixedly connected to the left side of the spring 524, and a rod 522 is fixedly connected to the left end of the pull plate 523, and the rod 522 is snapped with the inner surface of the slot 514.

[0044] In a specific implementation, the pull plate 523 is pulled to the right to completely disengage the plug rod 522 from the slot 514. This action is maintained and the plug plate 513 is slid upward to completely disengage the plug plate 513 from the mounting housing 521. At this time, the buckle assembly 5 no longer fixes the wrapping housing 1 and the wrapping housing 2 together, and the wrapping housing 1 can be opened to complete the work of placing the rectangular busbar connector in the wrapping housing 2;

[0045] After placing the rectangular busbar connector in the wrapping shell 2, pull the pull plate 523 to the right, and keep this action unchanged, so that the plug rod 522 will not hinder the process of inserting the plug plate 513 into the slot 514. At this time, the spring 524 is in a compressed state, and the wrapping shell 1 is covered, so that the plug plate 513 is fully inserted into the installation shell 521, so that the slot 514 is abutted against the lower side of the inner surface of the installation shell 521. At this time, the slot 514 and the plug rod 522 are in a facing position, and the pull plate 523 is released, so that the plug rod 522 is inserted into the slot 514, thereby completing the work of fixing the wrapping shell 1 and the wrapping shell 2 together by using the buckle assembly 5, so that the wrapping shell 1 will not be easily opened, causing damage to the rectangular busbar connector included in the wrapping shell 1 and the wrapping shell 2;

[0046] The fixing and opening process is simple and convenient, which provides convenience for the staff's specific operation process and saves time for the staff to complete the protection work of the rectangular busbar joint using the device.

[0047] The working principle of the utility model is:

[0048] Open the buckle assembly 5, then open the wrapping shell 1, place the rectangular busbar connector in the rectangular groove in the middle of the inner surface of the wrapping shell 2, plug the busbars to be connected into the left and right side sockets of the rectangular busbars, straighten the left and right side busbars, put them together on the left and right arc-shaped clamping plates 36 set in the wrapping shell 2, and then rotate the wrapping shell 1 to cover the wrapping shell 2;

[0049] Pull the pull plate 523 to the right to fully insert the plug plate 513 into the mounting housing 521, release the pull plate 523 to insert the plug rod 522 into the slot 514, and use the buckle assembly 5 to fix the wrapping housing 1 and the wrapping housing 2 together;

[0050] The two rotating handles 31 symmetrically distributed on the same side are rotated clockwise, thereby driving the two threaded rods 34 to rotate, thereby driving the two arc-shaped clamping plates 36 to move closer to each other until the busbar between the two is fixed firmly, and repeating the above operation, so that the two arc-shaped clamping plates 36 on the other side can also complete the fixing work of the busbar on the other side;

[0051] The two clip telescopic rods 6 are adjusted to a suitable length, and then the mounting plate 7 is fixed to the specific use position of the rectangular busbar joint by bolts.
