Description

Technical Field

[0001] The invention relates to the technical field of bus duct connectors, and in particular to a fast-assembly bus duct connector and an assembling method thereof. Background Art

[0002] The dense bus duct is an indispensable part of the power transmission and distribution process. It is a safe and reliable power distribution system because of its close arrangement of conductors, overall heat dissipation, compact structure, small footprint and easy use. It is widely used as a high-current and efficient power transmission and distribution system in large commercial plazas, real estate projects, hospitals, industrial plants and other projects.

[0003] When installing a dense bus duct, connectors are required to connect each section of the bus duct. The bus duct connectors currently on the market, such as the bus duct connector disclosed in patent number CN201320551962.7, are usually mainly composed of bolt fasteners, insulating plates, side plates and conductors, and the insulating plates, side plates and conductors are all mounted on the bolt fasteners through the center holes. Therefore, whenever assembly or parts need to be replaced, the bolt fasteners and the guard plates on both sides need to be removed, and then the insulating plates, side plates and conductors need to be installed in turn. When replacing, the bolt fasteners and the guard plates on both sides need to be removed, and then the insulating plates, side plates and conductors need to be removed in turn until the parts that need to be replaced are disassembled. This is time-consuming and labor-intensive, and it is impossible to achieve quick disassembly and assembly. Summary of the invention

[0048] Embodiment 1

[0049] The present invention provides a quick-assembly bus duct connector, see Figure 1 and Figure 2 , including at least two insulating partitions 1 spaced apart along the axial direction of the busbar fastening assembly 2, conductors 3 are embedded on both sides of the insulating partition 1, and a gap is left between two adjacent conductors 3 for plugging the busbar of the bus duct.

[0050] Guard plates 4 are slidably connected to both ends of the fastening assembly 2, and an insulating side plate 5 is provided on the side of the guard plate 4 close to the insulating partition 1; the fastening assembly 2 can tighten the guard plate 4, the insulating side plate 5, the insulating partition 1 and the conductor 3 toward the middle from both sides, and clamp and fix the busbar of the bus duct between the conductors 3.

[0051] like Figure 3 As shown, the fastening assembly 2 includes a polygonal mounting column 201 and a locking piece 202 connected to both ends of the polygonal mounting column 201, and the insulating partition 1, the conductor 3 and the insulating side plate 5 are all provided with a plug-in groove adapted to the polygonal mounting column 201, and the plug-in groove extends from the center to the bottom, so that the insulating partition 1, the conductor 3 and the insulating side plate 5 can be plugged and sleeved on the polygonal mounting column 201 from top to bottom.

[0052] In the embodiment of the present invention, the polygonal mounting column 201 is a hexagonal column, and screws 2011 are provided at both ends of the hexagonal column, so that the locking members 202 at both ends of the polygonal mounting column 201 are threadedly connected to the screws 2011.

[0053] For details, please refer to Figure 4 and Figure 5 The locking member 202 includes a sliding sleeve 2021 and a locking nut 2022 which are arranged in sequence. A hexagonal through hole which is adapted to the polygonal mounting column 201 is opened in the center of the sliding sleeve 2021, so that the sliding sleeve 2021 can slide on the polygonal mounting column 201; the locking nut 2022 is threadedly connected to the screw rod 2011, and the sliding sleeve 2021 is pushed to move from both ends to the middle by screwing the locking nut 2022.

[0054] In an embodiment of the present invention, the outer dimensions of the locking nut 2022 are greater than the outer dimensions of the sliding sleeve 2021, thereby ensuring that the locking nut 2022 can stably push the sliding sleeve 2021 to move from both ends to the middle when being screwed and moved along the axis.

[0055] In an embodiment of the present invention, one end of the sliding sleeve 2021 away from the locking nut 2022 contacts the guard plate 4, and the sliding sleeve 2021 contacts the guard plate 4 through a pressing plate, and the diameter of the pressing plate is much larger than the diameter of the sliding sleeve 2021, so that the contact area between the sliding sleeve 2021 and the guard plate 4 is increased, thereby ensuring the stability of the clamping force.

[0056] Furthermore, a buffer frame 401 is arranged on the contact surface between the guard plate 4 and the sliding sleeve 2021. The buffer frame 401 is L-shaped and symmetrically arranged on both sides of the sliding sleeve 2021. When the locking force of the locking nut 2022 is continuously transmitted from the sliding sleeve 2021 to the guard plate 4, the size of the clamping force can be judged by observing the deformation of the buffer frame 401, thereby avoiding damage to the insulating partition 1, the conductor 3, the insulating side plate 5, the guard plate 4 or the plug-in bus duct busbar due to excessive clamping force, or poor contact between the conductor 3 and the bus duct busbar due to insufficient clamping force.

[0057] For details, please refer to Figure 6 and Figure 7 A first conductor installation groove 501 is provided on the side of the insulating side plate 5 away from the protective plate 4 for installing the conductor 3, and the thickness of the conductor 3 is greater than the groove depth of the first conductor installation groove 501, so that the conductor 3 installed in the first conductor installation groove 501 protrudes from the surface of the insulating side plate 5; a positioning block 502 is extended from top to bottom on the side of the insulating side plate 5 close to the protective plate 4, and the positioning block 502 is adapted to the positioning groove on the contact surface of the protective plate 4. When the insulating side plate 5 and the protective plate 4 are tightly connected, the two are engaged and positioned, thereby reducing the installation position error of the two and facilitating the installation of the installation operator.

[0058] Furthermore, a side plate limiting convex ring 503 is provided at the center of the insulating side plate 5, and the length of the side plate limiting convex ring 503 is greater than the thickness of the conductor 3. When the conductor 3 is installed in the first conductor installation groove 501 of the insulating side plate 5, the conductor 3 is sleeved on the side plate limiting convex ring 503.

[0059] The center of the side plate limiting convex ring 503 is provided with a side plate hexagonal center groove 504 adapted to the polygonal mounting column 201. Through the clearance fit between the side plate hexagonal center groove 504 and the polygonal mounting column 201, the insulating side plate 5 is provided with a side plate plug-in groove 505, which extends from the side plate hexagonal center groove 504 to the bottom, so that the insulating side plate 5 can be plugged and sleeved on the polygonal mounting column 201 from top to bottom along the side plate plug-in groove 505. Figure 8 shown.

[0060] For details, please refer to Fig. 9 and Fig.10 , second conductor mounting grooves 101 are provided on both sides of the insulating partition 1 for mounting the conductor 3, and the thickness of the conductor 3 is greater than the groove depth of the second conductor mounting groove 101, so that the conductor 3 installed in the second conductor mounting groove 101 protrudes from the surface of the insulating partition 1, and a partition limiting convex ring 102 is provided in the center of the insulating partition 1, and the partition limiting convex ring 102 extends from the middle to both sides, and the length of one side located in the second conductor mounting groove 101 is greater than the thickness of the conductor 3. When the conductor 3 is installed in the second conductor mounting groove 101 of the insulating partition 1, the conductor 3 is sleeved on the partition limiting convex ring 102.

[0061] Among them, a partition hexagonal center groove 103 adapted to the polygonal mounting column 201 is opened in the center of the partition limiting convex ring 102, and the partition hexagonal center groove 103 is matched with the polygonal mounting column 201 through the clearance fit between the partition hexagonal center groove 103 and the polygonal mounting column 201. A partition plug-in groove 104 is opened on the insulating partition 1, and the partition plug-in groove 104 extends from the partition hexagonal center groove 103 to the bottom, so that the insulating partition 1 can be plugged and sleeved on the polygonal mounting column 201 from top to bottom along the partition plug-in groove 104.

[0062] For details, please refer to Fig.11 A conductor hexagonal center groove 301 is provided at the center of the conductor 3, and the conductor hexagonal center groove 301 is adapted to the partition limiting convex ring 102, so that when the conductor 3 is installed in the second conductor installation groove 101, the conductor 3 is sleeved on the partition limiting convex ring 102 through the conductor hexagonal center groove 301; a conductor plug-in groove 302 is also provided on the conductor 3, and the conductor plug-in groove 302 extends from the conductor hexagonal center groove 301 to the bottom, so that the conductor 3 can pass through the polygonal installation column 201 from top to bottom along the conductor plug-in groove 302 and be sleeved on the partition limiting convex ring 102.

[0063] Similarly, the conductor hexagonal center groove 301 is also adapted to the side panel limiting convex ring 503, so that when the conductor 3 is installed in the first conductor installation groove 501, the conductor 3 is sleeved on the side panel limiting convex ring 503 through the conductor hexagonal center groove 301; similarly, the conductor 3 can pass through the polygonal installation column 201 from top to bottom along the conductor plug-in groove 302 and be sleeved on the side panel limiting convex ring 503.
