Description

[Technical Field]

[0001] This invention relates to the docking and installation technology of busbar trunking in power systems, and more particularly to a busbar installation and connection machine with integrated shell and protection. [Background Technology]

[0002] Busbar trunking, as an important piece of equipment in power systems, has become a development trend in replacing existing cables. The connectors of busbar trunking are used to connect the main units of the busbar trunking and are important functional components for connecting the busbar trunking. When the busbar trunking is connected by the connector, the fastening bolts pass through the connector side plate, all the insulating partitions and all the conductor plates, thereby locking the connector side plate, insulating partitions and conductor plates into a whole.

[0003] However, with technological advancements, existing busbar connectors face increasingly stringent requirements for sealing and moisture resistance. Therefore, most current busbar connectors utilize integrated housing and insulation, a type of compact busbar connector. Unlike ordinary compact busbars, this integrated housing and insulation connector uses a three-layer polyester film instead of traditional insulating partitions to reduce the overall connector width and ensure rapid temperature dissipation and low temperature rise after the busbar circuit is in operation. Due to the thin and soft insulating film, coupled with the angled copper connecting pieces on both sides, the connector can only be installed horizontally. Significant friction exists between the two busbar copper busbars and the connecting pieces; therefore, manually pushing the busbars on both sides is insufficient for effective installation and connection. Effective installation tools are necessary to simultaneously move the corresponding busbars on both sides towards each other, allowing the connecting pieces to insert between the busbars on both sides.

[0004] To address the above technical challenges, patent publication number CN 210779991 U discloses a patent entitled "A Busbar Trunking Connection Device." When connecting two busbar trunks, the mounting plate and connecting plate located at the port of the connecting trunk are first inserted into the connection box. The connecting plate is then fitted into the connecting box. Next, the rotating ring is rotated, causing the threaded rod to rotate. The collar moves up and down due to the threaded thrust of the rotating threaded rod. The push plate pushes the two limiting rods to move up and down. When the upper and lower limiting rods move in opposite directions and are inserted into the connecting trunk, the connecting trunk will be constrained by the connection box, thus stabilizing the connecting trunk device and making the equipment convenient to use.

[0005] In addition, patent publication number CN 213125516 U discloses a patent entitled "A Connecting Frame for Busbar Trunking," which includes a first protective sleeve and a second protective sleeve. Sealing plates are fixedly inserted into both ends of the first protective sleeve, and two insertion rods are fixedly installed on both the upper and lower surfaces of the second protective sleeve. Two fixing mechanisms are fixedly installed on both the upper and lower surfaces of the first protective sleeve. This connecting frame for busbar troughs, by incorporating insertion rods, fixing mechanisms, pins, springs, and collars, solves the problem of inconvenient operation caused by difficulties in installation during use.

[0006] The two patents disclosed above have complex structures, making them inconvenient for positioning and fixing, and complicated to operate. They also make it difficult to quickly connect and install busbar trunking and connectors on site. This is especially true for existing dense busbar trunking with integrated housing and protection, which is inconvenient for assembly and use. There is an urgent need to develop a busbar trunking connection device that adapts to the current installation environment requirements. [Summary of the Invention]

[0007] The integrated housing and protection busbar installation and connection machine provided by the present invention realizes the docking and fixed installation of the connector with the busbar body on both sides through the unidirectional tensioning of the docking pull-in mechanism. It also has a self-locking function to prevent the busbar from springing back during the docking pull-in process. At the same time, the docking pull-in mechanism can be easily unlocked when it is pressed backward, which facilitates quick disassembly after assembly and effectively improves the convenience of busbar connection and the reliability of installation.

[0008] The technical solution adopted by this invention to solve its technical problem is:

[0009] The integrated casing and protection busbar installation and connection machine is used for the docking and fixing of connectors to the busbars on both sides of the busbar trunking body, including:

[0010] The double-sided busbar clamping and positioning device includes a first clamping and positioning mechanism and a second clamping and positioning mechanism for clamping and positioning the two sides of the busbar body respectively. The first clamping and positioning mechanism and the second clamping and positioning mechanism are U-shaped buckle bodies with the same structure, and they elastically open on one side along the width direction of each side of the two busbar bodies and adaptively fasten and lock to the edge of each side of the busbar body.

[0011] On the other side of the opening side between the first clamping and positioning mechanism and the second clamping and positioning mechanism, there is also a linear transverse guide mechanism for the connector to be linearly connected to the busbars of the busbar trunking body on both sides.

[0012] Between the first clamping and positioning mechanism and the second clamping and positioning mechanism, there is also a U-shaped buckle body located on both sides, with one end fixedly installed and the other end as a free end. Under the drive of external force, the busbars of the busbar trunking body on both sides are simultaneously pulled in opposite directions, and under the guidance of the linear transverse guide mechanism, they are transversely moved in a straight line and inserted into both ends of the connector.

[0013] Preferably, a support mechanism is installed on the bottom side of the two vertically placed busbar trunking bodies or in the middle of the bottom side between the two horizontally placed busbar trunking bodies to support the connector from the bottom side and prevent the connector from detaching from the busbar docking of the two busbar trunking bodies.

[0014] The support mechanism includes a support plate, a side hinge buckle assembly, and a two-end locking assembly. The two-end locking assemblies are respectively installed at both ends of the length direction on one side of the support plate and are locked and fixed to the bottom ends of two horizontally placed busbar trunking bodies. The side hinge buckle assembly is respectively installed at both ends of the width direction on the other side of the support plate relative to the two-end locking assemblies, and after being hinged and deflected at a certain angle on one side, it is elastically locked and fixed to the bottom sides of two vertically placed busbar trunking bodies along the width direction.

[0015] The two-end locking assembly includes two guide locking blocks and two L-shaped limiting members. The two guide locking blocks are symmetrically installed on both ends of one side of the support plate along the length direction via L-shaped end plates, and are used to snap and fix them in the groove in the middle of the bottom of the horizontally placed busbar trunking body. The two L-shaped limiting members are respectively adjacent to the two guide locking blocks and symmetrically installed on both ends of the support plate, and are used to limit and fix the connector from both sides.

[0016] The side-end hinge buckle assembly includes an L-shaped fixing plate and an L-shaped hinge locking plate. The L-shaped fixing plate and the L-shaped hinge locking plate are installed on both sides of the edge in the width direction of the support plate. The L-shaped hinge locking plate is symmetrically arranged opposite to the L-shaped fixing plate and is hinged to the other side edge of the support plate by a handle and a torsion spring. After the L-shaped hinge locking plate is deflected open, the support plate is locked to both sides of the connector in the width direction. On the other side of the support plate, L-shaped limiting plates are also symmetrically installed on both sides along the length direction, which cooperate with the L-shaped fixing plate and the L-shaped hinge locking plate to limit and fix the bottom ends of the connector.

[0017] Preferably, both the first clamping and positioning mechanism and the second clamping and positioning mechanism include a U-shaped groove buckle and a single-sided self-tensioning locking assembly. The U-shaped groove buckle is clamped and fixed to both sides of the busbar trunking body from the side along the width direction. The single-sided self-tensioning locking assembly is elastically self-lockingly hinged and installed on the side of the U-shaped groove buckle. It is used to overcome the self-locking torque at the hinge by external force, deflect the single-sided self-tensioning locking assembly at a certain angle, open it, and then fasten and lock the U-shaped groove buckle to both sides of the busbar trunking body.

[0018] The single-sided self-tensioning locking assembly includes a side locking plate, a hinge positioning plate, and a self-locking return torsion spring. The hinge positioning plate is installed on the top side adjacent to the corner of the U-shaped groove buckle. The side locking plate is rotatably installed on the hinge positioning plate on the upper side of the corner of the U-shaped groove buckle via a pin and a self-locking return torsion spring. The top side of the side locking plate extends upward and is fixedly fitted with a dynamic pressure handle that overcomes the return torque of the self-locking return torsion spring at the hinge and drives the side locking plate to open relative to the side of the U-shaped groove buckle.

[0019] The inner side of the U-shaped groove buckle and the inner side of the locking plate on the upper side of the single-sided self-tensioning locking assembly are respectively provided with at least one set of thrust blocks that engage with the side wall of the busbar body and are used to stop the thrust positioning on the rear side of the docking end face of the busbar body to facilitate the docking pull-in mechanism to drive the two sides of the busbar body to move laterally towards each other for docking.

[0020] A lifting handle is installed and fixed on the top side of the corner of the U-shaped groove body relative to the single-sided self-tensioning locking assembly. This handle is parallel to the dynamic pressure handle and is set in pairs for easy lifting and snapping to the two sides of the busbar trunk body.

[0021] The first clamping and positioning mechanism and the second clamping and positioning mechanism are respectively located on the side wall of the U-shaped groove opposite to the other side of the single-sided self-tensioning locking assembly, which are used to fix the two ends of the linear transverse guide mechanism.

[0022] Preferably, the linear transverse guiding mechanism includes at least two guide sliders and guide rails. At least one guide slider is installed at the U-shaped groove sidewall of the first clamping and positioning mechanism and at the U-shaped groove sidewall of the second clamping and positioning mechanism. All the guide sliders are coaxially mounted. The guide rails are cylindrical and are sleeved in the sliding guide holes at the center of all the guide sliders. The first clamping and positioning mechanism and the second clamping and positioning mechanism are connected by linear sliding cooperation of the guide sliders and the guide rails, and under the drive of the docking and pulling mechanism, they respectively drive the busbars of the two busbar trunking bodies on both sides to move laterally in a straight direction and dock at both ends of the connector.

[0023] Preferably, the docking and pulling mechanism includes a fixed base, a toothed rack, and a toothed rack pulling seat. One end of the toothed rack is fixedly installed on the top side of the U-shaped buckle body of the first clamping and positioning mechanism through the fixed base, and the other free end of the toothed rack is sleeved on the toothed rack pulling seat.

[0024] The rack and pinion traction seat is a U-shaped inclined plate seat. The lower part of the side end of the rack and pinion traction seat has a traction guide hole to facilitate the rack and pinion to pass through from the bottom. A rotating gear that meshes with the rack on the upper side of the rack and pinion is rotatably mounted on the rack and pinion traction seat via a pin. At the two ends of the pin corresponding to the rotating gear, a U-shaped rocker handle is coaxially mounted on the rack and pinion traction seat. This handle reciprocates and deflects the rotating gear, causing it to rotate continuously in the same direction and drive the rack and pinion to move laterally in the same direction. An L-shaped lever is hinged to the U-shaped cavity on the lower side of the rocker handle via a pivot to rotate the rotating gear. A self-tensioning contact torsion spring is coaxially mounted on the pivot corresponding to the L-shaped lever to drive the lower extension end of the L-shaped lever to automatically abut against the tooth groove of the rotating gear.

[0025] Preferably, the rack pull seat is also rotatably pinned to a U-shaped limiting block for limiting the reverse rotation of the rotating gear and synchronously locking and limiting the tensioned rack. The center of the U-shaped limiting block is coaxially fitted with a self-tensioning locking torsion spring that drives the U-shaped limiting block to contact the lower part of the tooth groove of the rotating gear.

[0026] The beneficial effects of this invention are:

[0027] The existing dense busbar trunking connectors use thin and soft insulating diaphragms, and the corresponding connecting pieces are angled and positioned on the left and right sides, resulting in horizontal installation of the connectors. This causes significant friction between the busbars and the connecting pieces, making it difficult to achieve an effective connection by manually pushing the busbars on both sides. In this invention, when the busbars on both sides are vertically or horizontally connected to the connector in the middle, the connector is first supported from the bottom by a supporting mechanism on both sides of the busbar trunking body. Then, the connecting machine is placed at both ends of the two connected busbar trunking bodies. The first and second clamping and positioning mechanisms on the double-sided busbar clamping and positioning device lock the frame at the end of each busbar trunking body. Next, the operator, through the effective cooperation of the linear transverse guide mechanism and the docking pull-in mechanism, drives the busbars of the two busbar trunking bodies to move in opposite directions simultaneously and dock them at both ends of the connector in a straight line.

[0028] Throughout the docking process, the self-locking unidirectional tensioning mechanism in the pull-in mechanism, controlled by the L-shaped lever and self-tensioning torsion spring, drives the rotating gear to rotate in one direction, pulling the rack in one direction for feed. This allows for step-by-step docking of the connector with the busbars on both sides of the busbar trunking. The U-shaped limiting block prevents the rotating gear from rotating in the opposite direction, achieving self-locking and effectively preventing the busbar trunking from springing back during the docking pull-in process. Simultaneously, when the docking pull-in mechanism reverses its pressure, the U-shaped lever touches the U-shaped limiting block in the opposite direction. The U-shaped limiting block is reset by the self-tensioning locking torsion spring, releasing the unidirectional self-locking restriction on the rotating gear's reverse rotation, enabling easy unlocking. This facilitates quick disassembly of the connector after the busbar trunking is assembled, effectively improving the convenience of busbar trunking connection and the reliability of installation.

[0048] Integrated busbar installation and connection machine with casing and protection, such as Figures 1 to 5 , Figure 9As shown, the connector 1 is used for docking and fixing the busbars of the two busbar trunking bodies 2. It includes a double-sided busbar clamping and positioning device a and a linear transverse guide mechanism 3. The double-sided busbar clamping and positioning device a includes a first clamping and positioning mechanism 4 and a second clamping and positioning mechanism 5 that clamp and position the two busbar trunking bodies 2 respectively. The first clamping and positioning mechanism 4 and the second clamping and positioning mechanism 5 are U-shaped buckles with identical structures, and they elastically open on one side along the width direction of each side of the two busbar trunking bodies 2 and adaptively fasten and lock to the edge of each side of the busbar trunking body 2. The linear transverse guide mechanism 3... On the other side of the relatively open side between the first clamping and positioning mechanism 4 and the second clamping and positioning mechanism 5, a guide mechanism is provided for the connector 1 to move laterally in a straight direction when it is directly connected to the busbars of the busbar bodies 2 on both sides; between the first clamping and positioning mechanism 4 and the second clamping and positioning mechanism 5, a docking pull-in mechanism 6 is also provided, which is located in the middle of the U-shaped buckle body on both sides, with one end fixed and the other end as a free end. Under the drive of external force, the busbars of the busbar bodies 2 on both sides are simultaneously pulled in opposite directions, and under the guidance of the straight lateral movement guide mechanism 3, the docking pull-in mechanism is inserted into both ends of the connector 1.

[0049] like Figures 1 to 5 As shown, both the first clamping and positioning mechanism 4 and the second clamping and positioning mechanism 5 include a U-shaped groove buckle 40 and a single-sided self-tensioning locking assembly 41. The U-shaped groove buckle 40 is clamped and fixed to both sides of the busbar trunking body 2 from the side along the width direction. The single-sided self-tensioning locking assembly 41 is elastically self-lockingly hinged and installed on the side of the U-shaped groove buckle 40. It is used to overcome the self-locking torque at the hinge and deflect the single-sided self-tensioning locking assembly 41 by 90° to open it and then fasten and lock the U-shaped groove buckle 40 to both sides of the busbar trunking body 2.

[0050] Continue as Figures 1 to 5As shown, the single-sided self-tensioning locking assembly 41 includes a side locking plate 410, a hinge positioning plate 411, and a self-locking return torsion spring 412. The hinge positioning plate 411 is installed on the top side of the U-shaped groove buckle 40, adjacent to the side corner. The side locking plate 410 is rotatably mounted on the hinge positioning plate 411 on the upper side of the corner of the U-shaped groove buckle 40 via a pin and the self-locking return torsion spring 412. The top side of the side locking plate 410 is connected to an upwardly extending and fixedly mounted dynamic pressure handle 413 that overcomes the return torque of the self-locking return torsion spring 412 at the hinge and drives the side locking plate 410 to open relative to the side of the U-shaped groove buckle 40. The inner side of the U-shaped groove buckle 40 and the side locking plate 410 on the single-sided self-tensioning locking assembly 41 are connected to the hinge. On the inner side, a pair of thrust blocks 414 are respectively set on opposite sides of the busbar trunking body 2 and are engaged with the side wall of the busbar trunking body 2. They are used to stop the thrust and position the busbar trunking body 2 on the rear side of the docking end face to facilitate the docking pull-in mechanism 6 to drive the two sides of the busbar trunking body 2 to move laterally towards each other for docking. On the other side of the self-tensioning locking assembly 41, the top side of the U-shaped groove buckle 40 extends upward and is installed and fixed. It is parallel to the dynamic pressure handle 413 and is set in pairs for easy lifting and locking on both sides of the busbar trunking body 2. The two ends of the linear transverse guide mechanism 3 are respectively fixed on the first clamping and positioning mechanism 4 and the second clamping and positioning mechanism 5 on the side wall of the U-shaped groove buckle 40 on the other side of the self-tensioning locking assembly 41.

[0051] like Figures 1 to 5 As shown, the linear transverse guide mechanism 3 includes four guide sliders 30 and cylindrical guide rails 31. Two coaxially arranged guide sliders 30 are installed on the side wall of the U-shaped groove buckle 40 of the first clamping and positioning mechanism 4 and the side wall of the U-shaped groove buckle 40 of the second clamping and positioning mechanism 5. All guide sliders 30 correspondingly arranged on both sides of the two busbar bodies 2 are coaxially installed. The guide rails 31 have a cylindrical structure and are sleeved in the sliding guide holes in the center of all guide sliders 30. The first clamping and positioning mechanism 4 and the second clamping and positioning mechanism 5 are connected to the connector 1 by the linear sliding cooperation of the guide sliders 30 and guide rails 31 and the drive of the docking and pulling mechanism 6, respectively driving the busbars of the two busbar bodies 2 to move laterally in a straight direction. Two guide sliders 30 are respectively placed on both sides of the cylindrical guide rails 31 on the linear transverse guide mechanism 3 to avoid misalignment and displacement when tightening and loosening.

[0052] like Figure 1 , Figures 5 to 8As shown, the docking and pulling mechanism 6 includes a fixed base 60, a toothed column 61, and a toothed pull seat 62. The toothed column 61 is a square column. One end of the toothed column 61 is fixedly installed on the top side of the U-shaped buckle body of the first clamping and positioning mechanism 4 through the fixed base 60. The other free end of the toothed column 61 is sleeved and installed on the toothed pull seat 62. The toothed pull seat 62 is a U-shaped inclined plate seat. A pull guide hole 620 is opened at the lower part of the side end of the toothed pull seat 62 to facilitate the toothed column 61 to pass through from the bottom. A pin is rotatably mounted on the toothed pull seat 62 to connect with the toothed column. The upper side of 61 has a rack meshing rotating gear 63. On the rack pull seat 62, at both ends of the pin corresponding to the rotating gear 63, there is a U-shaped rocker 64 that is coaxially installed to drive the rotating gear 63 to rotate continuously in the same direction after reciprocating back and forth, and to drive the rack 61 to move laterally in the same direction. In the U-shaped cavity on the lower side of the rocker 64, there is an L-shaped paddle 65 that is hinged to the rotating gear 63 for turning. On the rotating shaft corresponding to the L-shaped paddle 65, there is a self-tensioning contact torsion spring 66 that drives the lower extension end of the L-shaped paddle 65 to automatically abut against the tooth groove of the rotating gear 63.

[0053] Continue as Figure 1 , Figures 5 to 8 As shown, a U-shaped limiting block 67 is also rotatably pinned to the rack and pinion traction seat 62 to limit the reverse rotation of the rotating gear 63 and synchronously lock and limit the tensioned rack 61. A self-tensioning locking torsion spring 68 is coaxially mounted at the center of the U-shaped limiting block 67, driving the U-shaped limiting block 67 to contact the lower part of the tooth groove of the rotating gear 63. Thus, during the docking process of the two busbar trunking bodies 2, the U-shaped limiting block 67 can effectively prevent the rotating gear 63 from rotating in the opposite direction, achieving self-locking of the rotating gear 63 and effectively preventing the busbar trunking from springing back during the docking pull-in process. Simultaneously, when the docking pull-in mechanism 6 presses backward, the U-shaped seat handle 64 contacts the U-shaped limiting block 67 in the opposite direction, and the U-shaped limiting block 67 resets through the self-tensioning locking torsion spring 68, releasing the one-way self-locking limitation on the reverse rotation of the rotating gear 63, achieving easy unlocking, facilitating quick disassembly of the connecting machine after the busbar trunking is assembled, and effectively improving the convenience of busbar trunking connection and the reliability of installation.

[0054] like Figure 9 and Figure 10As shown, when the connector is used to connect a single row of locking connectors 1 to the busbar trunking bodies 2 on both sides, only one installation connector needs to be set on the same side of the busbar trunking bodies 2 at both ends. When the two horizontally arranged busbar trunking bodies 2 are connected to the connector 1 in the middle, only the first clamping and positioning mechanism 4 and the second clamping and positioning mechanism 5 need to be clamped at the busbar ends of the busbar trunking bodies 2 at the left and right ends respectively. In use, the self-tensioning locking components 41 that move on one side of the first clamping and positioning mechanism 4 and the second clamping and positioning mechanism 5 are used to press the dynamic pressure handle 413 respectively. Overcoming the torque of the self-locking reset torsion spring 412, the side locking plate 410 corresponding to the single-sided self-tensioning locking assembly 41 deflects 90° and opens; then, they are placed at the end of the busbar respectively. After releasing, the clamp formed by the U-shaped groove buckle 40 returns to its original position under the action of the self-locking reset torsion spring 412. The inner side of the U-shaped groove buckle 40 and the inner side of the single-sided self-tensioning locking assembly 41, a pair of mating thrust blocks 414 on the inner side of the U-shaped groove buckle 40 and the single-sided self-tensioning locking assembly 41, push against the attached side plate at the rear end of the busbar trunk body 2, so that the docking pull-in mechanism 6 can drive the two sides of the busbar trunk body 2 to move laterally towards each other for docking. Next, through the docking and pulling mechanism 6, which is fixed at one end and free at the other, the U-shaped rocker handle 64, driven by external force, deflects back and forth and then drives the rotating gear 63 on the rack and pinion 62 to rotate continuously in the same direction through the L-shaped lever 65. This drives the rack 61 to move laterally in the same direction, pulling the first clamping and positioning mechanism 4 and the second clamping and positioning mechanism 5 in opposite directions. This drives the busbars of the two busbar trunk bodies 2 to move laterally in a straight line and dock and insert into the two ends of the connector 1. After the connection is completed, press the dynamic pressure handles 413 on both sides again, the clamps open, and the entire connector can be easily removed.

[0055] exist Figure 9 and Figure 10 In the process, when the docking and pulling mechanism 6 is working, the U-shaped rocker handle 64 is driven by external force, and the rotating gear 63 is rotated and mounted on the rack and pinion traction seat 62 through a round pin. The rocker-type U-shaped rocker handle 64 is also fixed on the rack and pinion traction seat 62 through a round pin. When the U-shaped rocker handle 64 deflects and pushes, the U-shaped rocker handle 64 drives the L-shaped lever 65 to rotate the rotating gear 63. The rotating gear 63 drives the rack and pinion 61 to move horizontally backward. At this time, the connecting machine is in a tensioned state. When the U-shaped rocker handle 64 is pulled back reciprocally, the U-shaped limiting block 67 clamps the rotating gear 63 to prevent the toothed bar 61 from being loosened by the reverse force, thus achieving the purpose of unidirectional tightening; when the U-shaped rocker handle 64 is pressed back, the U-shaped limiting block 67 releases the clamp on the rotating gear 63, and the toothed bar 61 moves in the opposite direction relative to the toothed bar pull seat 62. The first clamping and positioning mechanism 4 and the second clamping and positioning mechanism 5 can be quickly pulled apart, which facilitates the quick disassembly of the connector 1 and the two side busbar trunking bodies 2.

[0056] like Figures 11 to 13As shown, for the docking of the multi-row locking connector 1 with the multi-row busbar trunking on both sides, for the vertically placed busbar trunking bodies, a support mechanism 7 is installed on the bottom side of the two vertically placed busbar trunking bodies to support the connector from the bottom side and prevent the connector from detaching from the busbar docking of the two busbar trunking bodies. Figures 14 to 16 As shown, for a horizontally placed busbar trunking body, a support mechanism 7 is also installed at the bottom center between two horizontally placed busbar trunking bodies to support the connector from the bottom and prevent the connector from detaching from the busbar docking of the two busbar trunking bodies; relative to the vertically placed busbar trunking body, it is locked and fixed by a component on one side of the support mechanism, while for the horizontally placed busbar trunking body, it is locked and fixed by a component on the other side after the support mechanism is rotated 180°.

[0057] like Figures 11 to 16 As shown, the support mechanism 7 includes a support plate 70, a side-end hinged buckle assembly 71, and a two-end locking assembly 72. The two-end locking assemblies 72 are respectively installed at both ends of the length direction on one side of the support plate 70 and are locked and fixed to the bottom ends of the two horizontally placed busbar trunking bodies. The side-end hinged buckle assembly 71 is respectively installed at both ends of the width direction on the other side of the support plate 70, and after being hinged and deflected at a certain angle on one side, it is elastically locked and fixed to the bottom sides of the two vertically placed busbar trunking bodies.

Through the first clamping and positioning mechanism 4 and the second clamping and positioning mechanism 5 on the double-sided busbar clamping and positioning device a, the frame at both ends of the busbar trunking is fastened and locked. The operator operates the connecting machine on the top side. Through the effective cooperation of the linear transverse guide mechanism 3 and the docking pull-in mechanism 6, the busbars of the two sides of the busbar trunking body 2 are driven to move in opposite directions at the same time and dock and insert into the two ends of the connector 1 in a straight line direction.
