Description

Technical Field

[0001] The invention relates to the field of busbar connection, and in particular to a protective busbar connection device. Background Art

[0002] Bus duct refers to a cable duct system used to fix and protect wiring in electrical installation. Nonferrous metal copper is used as a conductor in the bus duct to transmit high voltage electricity. The conductor copper bars are partially extended to the outside of both ends of the bus duct for connection between bus ducts. Two bus ducts are connected by connectors. The connector consists of multiple connecting pieces, pressure plates on both sides, a connecting shaft in the middle and fastening bolts. When the existing connector is installed, the corresponding connecting pieces are inserted between the copper bars on the same straight line of the bus ducts on both sides for communication. The connecting pieces are arranged on the connecting shaft in a movable state, which makes it difficult to align the gaps between the connecting pieces and the copper bars when installing the connector, resulting in low installation efficiency.

[0003] In addition, when installing the connector, manual pressure needs to be continuously applied to insert the connector. The connecting piece is composed of a middle insulating piece and conductive pieces on both sides. At this time, the connecting piece and the copper busbar are in the same straight line, and the two squeeze each other, which can easily damage and deform the insulating piece, thereby affecting the insertion of the connecting piece between the copper busbars. Summary of the invention

[0004] In order to overcome the disadvantages that movable connecting pieces make it difficult to align the gaps between the connecting pieces and the copper busbars when installing the connector, and that continuous manual pressure is applied during installation so that the connecting pieces and the copper busbars are squeezed against each other in the same straight line, which easily causes the insulating piece to be damaged and deformed, the present invention provides a protective busbar connecting device.

[0005] The technical implementation scheme of the present invention is: a protective busbar connection device, including a mounting plate; a handle is fixedly connected to the mounting plate; it also includes a clamping frame and a slide bar; a plurality of clamping frames are connected to the mounting plate; a toggle portion I is provided on each mounting plate; a plurality of slide grooves are provided on the mounting plate; a plurality of sliders are fixedly connected to the toggle portion; each slider is correspondingly located in a slide groove; a movable groove is provided on the mounting plate; a plurality of slide bars are connected to the mounting plate; the slide bar is located in the movable groove; a toggle portion II is fixedly connected to each slide bar; a plurality of splints are fixedly connected to each slide bar; all slide bars slide relatively on the mounting plate; the splints on all slide bars are interlaced with each other.

[0006] Optionally, a rubber block is fixedly connected to both ends of the mounting plate.

[0007] Optionally, a positioning groove is provided on the clamping frame.

[0008] Optionally, a pull rod is fixedly connected to the toggle portion II.

[0009] Optionally, the upper side of the clamping frame covers the slide bar to shield the upper portion of the movable groove of the slide bar to prevent debris from falling in and affecting the movement of the slide bar.

[0010] Optionally, a rubber layer is provided on the inner side of the clamping frame.

[0011] Optionally, it also includes a connecting block; a connecting block inside the handle; and a plurality of pressing blocks fixedly connected to the connecting block.

[0012] Optionally, the lower side of the pressing block is arc-shaped.

[0013] Optionally, a sponge layer is provided on the surface of the splint.

[0014] Optionally, an N-shaped groove is provided on the lower side of the clamping plate.

[0015] The present invention has the following advantages: the present invention realizes that the gaps between the connecting pieces are kept consistent through the clamping plate, thereby preventing the connecting pieces from being in a movable state. When installing the connector, the gaps between the connecting pieces and the copper bar of the bus duct are difficult to align, resulting in low installation efficiency and the problem of mutual squeezing between the connecting pieces and the copper bar.

[0016] Through the use of pressure blocks of different lengths, each connecting piece is flipped at different angles on the connecting axis, so that each connecting piece is misaligned at an angle. During installation, workers can clearly distinguish each connecting piece from the front and back directions, avoiding visual errors that may cause workers to insert the connecting piece into the wrong gap.

[0017] The gap and angle of the connecting piece can be adjusted by the cooperation between the clamping frame, the clamping plate and the pressing block, so the user does not need to put his fingers in to adjust the connecting piece to avoid hand injury.

[0018] When the connector is installed on the present invention, the worker rotates the connector to contact the sponge layer of the clamping plate, and wipes and cleans the connecting piece to ensure that the contact surface of the connecting piece is clean, thereby ensuring that the connector has good conductivity after installation.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0027] Example 1

[0028] like Figure 1-Figure 5 As shown, a protective busbar connection device includes a mounting plate 1; a handle 1001 is fixedly connected to the mounting plate 1;

[0029] It also includes a clamping frame 2 and a slide bar 3; two clamping frames 2 are connected to the mounting plate 1 in a damped sliding manner; each mounting plate 1 is provided with a toggle portion Ⅰ2001 on the side facing the handle 1001; four front-to-back symmetrical slide grooves 1002 are provided on the mounting plate 1; two sliders 2002 are fixedly connected to the lower side of the toggle portion; each slider 2002 is correspondingly located in a slide groove 1002; a movable groove is provided on the mounting plate 1; two slide bars 3 are connected to the mounting plate 1 in a damped sliding manner; the slide bar 3 is located in the movable groove; each slide bar 3 is fixedly connected to a toggle portion Ⅱ3001; six clamping plates 3002 are fixedly connected to the lower side of each slide bar 3; all slide bars 3 slide relatively on the mounting plate 1; the clamping plates 3002 on all slide bars 3 are interlaced with each other.

[0030] A rubber block 1003 is fixedly connected to both ends of the mounting plate 1 to flatten the connecting piece of the connector 2222 .

[0031] A positioning groove 2003 is provided on the clamping frame 2 , and the position of the connector 2222 is positioned in the positioning groove 2003 by a nut in the middle of the connector 2222 .

[0032] A pull rod is fixedly connected to one side of the toggle part II 3001 away from the handle 1001, so as to facilitate the separation of the toggle parts II 3001 when they are closely attached to each other.

[0033] The upper side of the clamping frame 2 covers the slide bar 3 to block the upper portion of the movable groove of the slide bar 3 to prevent debris from falling in and affecting the movement of the slide bar 3 .

[0034] A rubber layer is provided on the inner side of the clamping frame 2 to increase the friction force when clamping the connector 2222 .

[0035] The connecting piece of the existing connector 2222 is arranged in a movable state on the connecting shaft, which makes it difficult to align the gaps between the connecting pieces and the copper bars of the bus duct 1111 when installing the connector 2222, resulting in low installation efficiency. The connecting piece is composed of a middle insulating piece and conductive pieces on both sides. When the connecting piece is not aligned with the gaps between the copper bars and is in the same straight line as the copper bars, the two are squeezed against each other, which can easily damage and deform the insulating piece, thereby affecting the connection piece from being stuck between the copper bars.

[0036] The use process of the present invention is as follows:

[0037] First, the worker manually moves the toggle part I 2001 to move the two clamping frames 2 away from each other to expand the gap, and then manually moves the toggle part II 3001 to make the two close together. The toggle part II 3001 moves to drive the slide bar 3 and the corresponding clamping plate 3002 close together, and then the clamping plates 3002 on the lower sides of the two slide bars 3 are interlaced and close together as shown in the figure. Figure 5 As shown; then the worker places the connector 2222 from the lower side of the mounting plate 1 upward between the clamping frames 2. At this time, the two adjacent clamping plates 3002 are inserted between the connecting plates. The two clamping plates 3002 are close to each other and are much smaller than the gap between the connecting plates. The connector 2222 can be smoothly inserted. After the connector 2222 is placed, the worker manually moves the toggle part Ⅰ2001 to make the two clamping frames 2 approach each other, clamp the two sides of the connector 2222, and at the same time make the fastening bolts of the connector 2222 be located in the positioning groove 2003 for left and right positioning. Then, the pull rods of the two toggle parts Ⅱ3001 are pulled to move the two away from each other, and the clamping plates 3002 inserted between the connecting plates are moved away, and at the same time, the connecting plates are driven to move, so that the gaps between the connecting plates are kept consistent, thereby avoiding the connecting plates from being in a movable state. When installing the connector 2222, it is difficult to align the gaps between the connecting plates and the copper busbars of the bus duct 1111, resulting in low installation efficiency and the problem of mutual squeezing between the connecting plates and the copper busbars.

[0038] When installing connector 2222, the worker holds handle 1001 so that the present invention drives connector 2222 to be pressed into the copper busbar. When the lower sides of all connecting plates are inserted into the gap and the lower side of clamp 3002 is against the top of the copper busbar, the present invention reaches the installation limit. The worker moves toggle part II 3001 so that the two are close to each other and fit together. The toggle part II 3001 moves to drive the slide bar 3 and the corresponding clamp 3002 to move close to each other, releasing the contact limit between the clamp 3002 and the connecting plate. Then, the toggle part I 2001 is moved so that the two clamping frames 2 are away from each other, and then the present invention is moved upward to disengage from connector 2222. At this time, connector 2222 is in a half-stuck copper busbar state. The worker holds handle 1001 so that mounting plate 1 is in a vertical state, and squeezes the upper side of connector 2222 through rubber block 1003 to completely insert it into the copper busbar, completing the installation of connector 2222.

[0039] Example 2

[0040] On the basis of Example 1, Figure 3-Figure 6 As shown, it also includes a connecting block 4; the connecting block 4 is connected to the right side of the handle 1001 in a damping sliding manner; and four pressing blocks 4001 are fixedly connected to the lower side of the connecting block 4.

[0041] The lower side of the pressing block 4001 is arc-shaped to avoid scratching the side surface of the connector 2222 when entering between the connecting pieces.

[0042] During the process of inserting the connector 2222 into the copper busbar, since the specifications and colors of the connecting pieces are the same, when the connecting pieces are close to each other, visual errors occur, which can easily cause workers to insert the connecting pieces into the wrong gaps, and then need to pull them out and reinstall them, affecting efficiency; after the connector 2222 is installed on the present invention, the clamping frame 2 fixes the connector 2222 from both sides, and the worker presses the connecting block 4 by hand to move it toward the connector 2222, and then each pressing block 4001 gradually squeezes one side of the corresponding connecting piece, so that the connecting piece rotates on the connecting shaft, such as Figure 6 As shown, since the lengths of the pressing blocks 4001 are different, the flipping angles of the connecting pieces are also different, which results in angular misalignment of the connecting pieces. During installation, workers can clearly distinguish each connecting piece from the front and back directions, thus avoiding visual errors that may easily cause workers to insert the connecting pieces into the wrong gaps.

[0043] When installing connector 2222, an angle misalignment is formed through each connecting piece, and the lower side of the connecting piece with the largest angle enters the corresponding gap first, and the subsequent connecting pieces gradually enter until the present invention reaches the installation limit. At this time, the worker moves the toggle part II 3001 to bring the clamping plates 3002 closer, releases the contact limit between the clamping plates 3002 and the connecting pieces, and then moves the toggle part I 2001 to make the two clamping frames 2 move away from each other, and then moves the present invention upward to disengage from connector 2222; finally, the mounting plate 1 is in a vertical state, and the rubber block 1003 squeezes the upper side of the connector 2222 to completely insert it into the copper busbar, while the present invention moves left and right during the downward pressing process, and the rubber block 1003 flattens the connecting pieces with various angle misalignments to complete the insertion of connector 2222. Finally, the worker tightens the bolts of connector 2222 to complete the installation of connector 2222.

[0044] In summary, the connecting pieces are pressed by the pressing block 4001 so that each connecting piece is formed as follows. Figure 6 The angle misalignment shown allows workers to clearly distinguish each connector from the front and back directions during installation, avoiding visual errors that could easily cause workers to insert the connector into the wrong gap.

[0045] In particular, when installing the existing connector 2222, due to the small operating space, the user needs to use his fingers to move and align the connecting piece. Most of the surrounding parts are made of metal, which can easily hurt the user's fingers. During the above working process, the present invention adjusts the gap and angle of the connecting piece through the cooperation between the clamping frame 2, the splint 3002 and the pressing block 4001. The user does not need to insert his fingers to move and align the connecting piece, thereby avoiding hand injuries.

[0046] Example 3

[0047] On the basis of Example 2, Figure 1-Figure 4 As shown, a sponge layer is provided on the side of the splint 3002 that contacts the connecting piece, for wiping and cleaning the connecting piece.

[0048] An N-shaped groove is provided on the lower side of the clamping plate 3002 to avoid the connecting shaft on the connector 2222 passing through the middle of each connecting piece, while increasing the downward extending area of ​​the clamping plate 3002 to ensure a stable release from the connecting piece.

[0049] After the connector 2222 is placed on the present invention and before installation, the splints 3002 are in a state of being away from each other, the sponge layer of the splint 3002 is in contact with the adjacent connecting piece, and the connecting axis of the connector 2222 is stuck in the N-shaped groove of each splint 3002. At this time, the worker holds one side of the connecting axis on the connector 2222 from the clamping frame 2, and rotates the connector 2222 relative to the splint 3002, so that the sponge layer of the splint 3002 and the connecting piece rub against each other. When the connecting piece rotates, the sponge layer of the splint 3002 that does not completely cover the connecting piece can contact the entire side of the connecting piece, wipe the connecting piece, ensure that the contact surface of the connecting piece is clean, and then ensure that the connector 2222 has good conductivity after installation.
