Description

Technical Field

[0001] The utility model relates to the technical field of joint side plates for bus ducts, and more specifically, to a self-adjusting and positioning bus duct joint side plate. Background Art

[0002] With the emergence of modern engineering facilities and equipment, the electricity consumption in all walks of life has increased rapidly. Especially with the emergence of numerous high-rise buildings and large factory workshops, traditional cables as transmission conductors can no longer meet the requirements in large-current transmission systems. The parallel use of multiple cables brings many inconveniences to on-site installation and construction connections. Plug-in bus ducts emerge as a new type of distribution conductor. Compared with traditional cables, it fully demonstrates its superiority in large-current transmission.

[0003] The joint side plate of the bus duct mainly plays the role of electrical connection of the outer shell between two sections of bus ducts, and can also play a protective role for the intermediate conductor during transportation and installation.

[0004] The currently applied joint side plates are usually made of aluminum plates or steel plates. The overall strength of the side plates is relatively low, and the heat dissipation performance is poor. At the same time, after being clamped by the connector, the small side of the joint side plate is separated from the bus duct and a gap is generated, resulting in a decrease in the protection level.

[0005] In summary, how to avoid the occurrence of gaps at the connection between the joint side plate and the bus duct is an urgent problem to be solved by those skilled in the art at present. Content of the Utility Model

[0006] In view of this, the purpose of the utility model is to provide a self-adjusting and positioning bus duct joint side plate, which effectively avoids the occurrence of gaps at the connection between the joint side plate and the bus duct, thereby effectively avoiding the decrease in the protection level.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A self-adjusting and positioning bus duct joint side plate is used for being arranged at the end of one side of the bus duct. It includes a side plate main body, and the side plate main body includes a short side plate and a long side plate. The main bodies of the short side plate and the long side plate are vertically arranged, and the short side plate is used for being connected with the bus duct;

[0009] The long side plate includes a bent plate and a flat plate arranged in sequence. The bent plate is composed of a plurality of V-shaped telescopic adjustment structures. One side of the bent plate is connected with the short side plate, and the other side is connected with the flat plate.

[0010] Preferably, the bent plate includes two V-shaped telescopic adjustment structures, and the two V-shaped telescopic adjustment structures are arranged side by side along the long side plate.

[0011] Preferably, the pointed end of the V-shaped telescopic adjustment structure is arranged towards the side of the busbar trunking, and the open end of the V-shaped telescopic adjustment structure and the flat plate are located on the same vertical plane.

[0012] Preferably, a sealing connection structure is arranged on the flat plate, and the sealing connection structure is used for fixedly connecting the side plate body to the fully enclosed plate.

[0013] Preferably, the sealing connection structure includes a positioning groove arranged on the flat plate. The two ends of the positioning groove are flush with the upper and lower ends of the flat plate respectively. The positioning groove is concave-shaped, and a plurality of fixing nuts are fixedly arranged in the positioning groove. The fixing nuts cooperate with fixing bolts to fixedly connect the side plate body to the fully enclosed plate.

[0014] Preferably, the sealing connection structure includes a positioning groove arranged on the flat plate. Both ends of the positioning groove are flush with the upper and lower ends of the flat plate. The positioning groove is concave-shaped, and a plurality of fixing nuts are slidably arranged in the positioning groove. The fixing nuts are rectangular nuts, and the fixing nuts cooperate with fixing bolts to realize the fixed connection between the side plate body and the fully enclosed plate.

[0019] The beneficial effects of the self-adjusting busbar trunking joint side plate provided by the present utility model are as follows: by setting the long side plate of the side plate body into a V-shaped telescopic adjustment structure and a flat plate, after the long side plate of the side plate body is squeezed, the V-shaped telescopic adjustment structure close to the squeezing part bends outwards, while the short side plate still remains horizontal and the flat plate still remains vertical, thus effectively avoiding gaps at the connection between the short side plate and the busbar trunking, and further forming a better sealed space without reducing the protection level.

[0020] In the further solution provided by this application, at least one of the following beneficial technical effects can also be achieved:

[0021] With the help of the V-shaped telescopic adjustment structure, the contact area between the side plate body and the air is increased, thus effectively increasing the heat dissipation area, and further effectively improving the heat dissipation effect of the joint side plate;

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Unless otherwise defined, the technical terms or scientific terms used in this application disclosure should have the ordinary meaning understood by those of ordinary skill in the field to which the present invention belongs. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Inside", "outside", etc. are only used to represent relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly. This application embodiment discloses a self-adjusting belt-positioning busbar joint side plate.

[0035] The core of the present invention is to provide a self-adjusting belt-positioning busbar joint side plate.

[0036] The currently applied joint side plates are usually made of aluminum plates or steel plates. The overall strength of the side plates is relatively low, and the heat dissipation performance is poor. At the same time, after being clamped by the connector, the small side of the joint side plate is separated from the busbar and a gap is generated, resulting in a decrease in the protection level. And it cannot effectively position the distance between the two busbars. Although the current products are provided with positioning ribs at the side plate profiles of the busbar connectors, since they cannot be completely visually observed during the internal installation process, it is easy to cause the positioning ribs to press on the joint side plate during the connector connection process, resulting in loose clamping and causing electrical disasters.

[0037] Please refer to Figures 1 to 6 , in which Figure 1 is an axonometric schematic diagram of the overall structure of the joint side plate, Figure 2 is a top view of the joint side plate structure, Figure 3 is a schematic diagram of the force deformation of the joint side plate, Figure 4 is a schematic diagram of the joint side plate installed on the busbar, Figure 5 is a schematic diagram of the connection of two busbars, Figure 6 is a top view of the connection of two busbars.

[0038] The self-adjusting belt-positioning busbar trough joint side plate provided by the present utility model, the joint side plate is used to be arranged at the end of one side of the busbar trough 2. The self-adjusting belt-positioning busbar trough joint side plate includes a side plate main body 1. The side plate main body 1 includes a short side plate 11 and a long side plate 12. The main bodies of the short side plate 11 and the long side plate 12 are vertically arranged. The short side plate 11 is used to be connected with the busbar trough 2. The long side plate 12 includes a bent plate and a flat plate arranged in sequence. The bent plate is composed of a plurality of V-shaped telescopic adjustment structures 121. One side of the bent plate is connected with the short side plate 11, and the other side is connected with the flat plate.

[0039] The short side plate 11 of the side plate main body 1 is fixedly connected with the end connector 4 on the busbar trough 2 through bolts. Two relatively arranged side plate main bodies 1 are fixedly connected to one end of each busbar trough 2. The short side plates 11 of the two side plate main bodies 1 are adjacent to each other and the two long side plates 12 are arranged in parallel, so as to place the conductor of the busbar trough 2 between the two side plate main bodies 1. When two busbar troughs 2 are connected by a connector 6, the connector 6 will give the long side plate 12 of the side plate main body 1 a squeezing force towards the conductor, thus causing the deformation of the side plate main body 1. However, due to the setting of the V-shaped telescopic adjustment structure 121 in this embodiment, when the long side plate 12 is subjected to the squeezing force, the V-shaped telescopic adjustment structure 121 near the squeezing part bends towards the direction away from the short side plate 11. During the bending process, due to the existence of the V-shaped telescopic adjustment structure 121, it will not directly bend at the connection between the long side plate 12 and the short side plate 11, thereby avoiding the situation that the short side plate 11 is lifted during the bending process of the long side plate 12, and further avoiding the gap between the short side plate 11 and the busbar trough 2, so as to form a better sealed space. At the same time, referring to Figure 3 , the dotted line is the position of the side plate main body 1 after the side plate main body 1 is deformed by force. After the side plate main body 1 is subjected to an external force, except for the V-shaped telescopic adjustment structure 121 near the flat plate side bending slightly inwards, the rest of the structures remain in a "horizontal and vertical" state and will not generate an arc like the joint side plate made of aluminum plate.

[0040] The above-mentioned self-adjusting belt-positioning busbar trough joint side plate effectively solves the problem of gaps appearing at the connection between the joint side plate and the busbar trough after two busbar troughs 2 are connected by a connector 6, and thus effectively forms a better sealed space, ensuring the stability of the protection level without reduction.

[0041] The following will introduce the self-adjusting belt-positioning busbar trough joint side plate provided by the present utility model in more detail with reference to the accompanying drawings and specific embodiments.

[0042] In a specific embodiment, referring to Figure 1, the bending plate includes two V-shaped telescopic adjustment structures 121, and the two V-shaped telescopic adjustment structures 121 are arranged side by side along the long side plate 12. The arrangement of the two V-shaped telescopic adjustment structures 121 can ensure the normal operation of the bending plate while avoiding the structural complexity of the overall side plate main body 1 caused by too many V-shaped telescopic adjustment structures 121. At the same time, the two V-shaped telescopic adjustment structures 121 can further increase the contact area between the long side plate 12 and the air, thereby further improving the heat dissipation performance of the joint side plate.

[0043] Based on any one of the above embodiments, referring to Figure 1 and Figure 6 , the pointed end of the V-shaped telescopic adjustment structure 121 is arranged towards the side of the busbar groove 2, and the open end of the V-shaped telescopic adjustment structure 121 is on the same vertical plane as the flat plate. The arrangement of the pointed end of the V-shaped telescopic adjustment structure 121 facing outwards can effectively avoid interference between the V-shaped telescopic adjustment structure 121 and the conductor in the busbar groove 2, and avoid affecting the connection of the two busbar grooves 2.

[0044] Based on any one of the above embodiments, referring to Figure 1 , Figure 2 and Figure 5 , a sealing connection structure 120 is arranged on the flat plate, and the sealing connection structure 120 is used to fixedly connect the side plate main body 1 to the fully enclosed plate 5. The use of the sealing connection structure 120 facilitates the fixed connection between the side plate main body 1 and the fully enclosed plate 5, and thus facilitates the installation of the fully enclosed plate 5.

[0045] Further, referring to Figure 1 and Figure 6 , the sealing connection structure 120 includes a positioning groove 122 arranged on the flat plate. Both ends of the positioning groove 122 are flush with the upper and lower ends of the flat plate. The positioning groove 122 is concave-shaped, and a plurality of fixing nuts 123 are fixedly arranged in the positioning groove 122. The fixing nuts 123 cooperate with fixing bolts 124 to realize the fixed connection between the side plate main body 1 and the fully enclosed plate 5. During the threaded cooperation between the fixing bolts 124 and the fixing nuts 123, the side plate main body 1 and the fully enclosed plate 5 can be fixed by tightening the fixing bolts 124. Thus, after the connector 6 is installed, the fully enclosed plate 5 can be easily installed with only one wrench. And joint cover plates 3 are provided on both the upper and lower sides of the connection part of the two busbar grooves 2. Through the cooperation of the joint cover plates 3, the positioning groove 122 and the fully enclosed plate 5, the fixing bolts 124 can be completely enclosed in the positioning groove 122, thereby effectively preventing the operation of non-professional outsiders and playing a sealing role, effectively improving the protection level at the connector 6, and the highest protection level can reach IP66.

[0046] In some other embodiments, the fixing nut 123 can be slidably arranged in the positioning groove 122, and the fixing nut 123 is a rectangular nut. The fixing nut 123 is attached to the outer side wall of the inner side of the positioning groove 122. During the threaded engagement between the fixing bolt 124 and the fixing nut 123, since the fixing nut 123 is a rectangular nut and is limited in the positioning groove, the fixing between the side plate main body 1 and the fully enclosed plate 5 can be completed by tightening the fixing bolt 124. By using the slidably arranged fixing nut 123, different models of fully enclosed plates 5 can be better adapted.

[0047] In a specific embodiment provided by the present application, with reference to Figure 1 and Figure 6 , a positioning surface 125 is formed on the side of the positioning groove 122 away from the bending plate. The positioning surface 125 is horizontally arranged and abuts against the end of the connector 6. The positioning surface 125 is perpendicular to the surface of the flat plate and is used for positioning during the connection of the connector 6. And during the installation of the connector 6, the positioning surface 125 is obvious at a glance during installation, different from the previous internal positioning, and the installation state is obvious, which can well ensure the horizontality and verticality of the installation.

[0048] Based on any one of the above embodiments, with reference to Figure 4 , the short side plate 11 is provided with a fixing groove, and the fixing groove and the end connector 4 of the busbar 2 are fixedly connected by bolts, thereby facilitating the improvement of the installation efficiency of the short side plate 11 and enabling the quick completion of the installation and separation from the end connector 4.

[0049] Based on any one of the above embodiments, with reference to Figure 1 , the side plate main body 1 is an integrally formed structure, and the side plate main body 1 is extruded from an aluminum-magnesium alloy profile. Optionally, the side plate main body 1 can be extruded from a 6063 aluminum-magnesium alloy profile and subjected to T6 aging treatment. By strictly controlling the raw material quality, heating temperature, extrusion speed, quenching and cooling speed, and aging process parameters, etc., to ensure that the side plate main body 1 has good mechanical properties, high structural strength, and good heat dissipation performance.

[0050] The implementation principle of the self-adjusting busbar joint side plate with positioning in the embodiment of the present application is as follows: When connecting two busbars 2, the connector 6 is positioned through the positioning surface 125 on the positioning groove 122, and then the installation of the fully enclosed plate 5 is completed by using the cooperation between the fixing nut 123 and the fixing bolt 124.

[0051] When the side plate body 1 is subjected to force extrusion, the V-shaped telescopic adjustment structure 121 near the extrusion part bends away from the short side plate 11. During the bending process, due to the existence of the V-shaped telescopic adjustment structure 121, it will not directly bend at the connection between the long side plate 12 and the short side plate 11, thus avoiding the situation that the short side plate 11 is lifted during the bending process of the long side plate 12, and further preventing a gap from appearing between the short side plate 11 and the busway 2, thereby forming a better sealed space.

[0052] The above has introduced in detail a self-adjusting busway joint side plate provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the present utility model.
