[0001] The utility model relates to the technical field of electric power equipment, and more specifically, to a plug-in copper column busbar. Background Art

[0002] The busbar is a large current conductive product with the advantages of low resistivity and large bending degree. It is widely used in electrical engineering such as high and low voltage electrical appliances and distribution equipment. At present, in the power system and electrical equipment manufacturing industry, the busbar is an important conductive component, mainly used for collecting, distributing and transmitting electric energy, and is widely used in various power equipment such as switch cabinets, transformers, motors, new energy equipment, etc.

[0003] For example, application publication number CN 108039227 A discloses a copper busbar, comprising a copper busbar substrate, a connecting hole being arranged on the copper busbar substrate, a bendable copper busbar soft substrate being arranged on the copper busbar substrate, the copper busbar soft substrate being welded to the copper busbar substrate, the copper busbar soft substrate being paved with copper sheets, and the copper busbar soft substrate being welded to the copper busbar substrate by silver soldering.

[0004] In the above, welding is used, which has limitations. During the welding process, the installation time of the busbar is increased, which leads to a decrease in its working efficiency and affects the operating stability of the copper column busbar. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a pluggable copper column busbar which shortens the installation time of the busbar, improves work efficiency and ensures operational stability.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pluggable copper column busbar comprises an upper conductor and a lower conductor. A copper column is provided on the lower conductor, and the copper column is connected to the top surface of the lower conductor. An annular convex part is provided on the top surface of the copper column, and a connecting column is provided on the annular convex part. The annular convex part is placed between the connecting column and the copper column and is connected to the connecting column and the copper column. The annular convex part is elastic. A copper sleeve is provided on the upper conductor, and the copper sleeve is connected to the bottom surface of the upper conductor. The copper column is movably connected to the copper sleeve. The copper sleeve has an accommodating chamber, and the accommodating chamber is adapted to the annular convex part. A snap-in groove adapted to the connecting column is opened on the accommodating chamber, and the accommodating chamber is communicated with the snap-in groove so that the connecting column passes through the accommodating chamber and extends into the snap-in groove to be spirally connected to the snap-in groove. The annular convex part is placed in the accommodating chamber and connected to the accommodating chamber.

[0008] The utility model is further configured as follows: an external thread is arranged on the outer wall of the connecting column, and an internal thread spirally connected to the external thread is arranged on the inner wall of the clamping groove.

[0009] The utility model is further configured as follows: a plug-in hole is opened on the upper conductor, and the copper sleeve is placed in the plug-in hole and connected to the plug-in hole.

[0010] The utility model is further configured as follows: a placement groove is provided on the lower conductor, and the copper column extends into the placement groove and is connected to the placement groove.

[0011] The utility model is further configured as follows: the diameter of the accommodating chamber is larger than the diameter of the clamping notch.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are:

[0013] The connecting column is passed through the accommodating chamber and extended into the snap-in groove and screwed into the snap-in groove. At the same time, the annular protrusion is snap-fitted and fixed to the accommodating chamber. Since the copper column and the copper sleeve are tightly fixed by a special locking mechanism, good electrical contact and operating stability are guaranteed. Due to the internal thread, external thread and elastic annular protrusion, a plug-in design is adopted. The copper column and the copper sleeve are screwed in or pressed to quickly fix the upper conductor and the lower conductor. No complicated welding process is required, only simple insertion and fixing operations are required, which greatly shortens the installation time of the busbar and significantly improves work efficiency.

[0020] like Figures 1 to 3 As shown, the pluggable copper column busbar includes an upper conductor 1 and a lower conductor 2. A placement groove is provided on the lower conductor 2. The placement groove is placed on the top surface of the lower conductor 2. A copper column 3 is installed in the placement groove. The copper column 3 extends into the placement groove and is fixed to the placement groove. The copper column 3 and the placement groove are integrally formed.

[0021] An annular protrusion 4 is installed on the top surface of the copper column 3, and a connecting column 5 is arranged on the annular protrusion 4. The annular protrusion 4 is placed between the connecting column 5 and the copper column 3 and is connected to the connecting column 5 and the copper column 3. The annular protrusion 4 is elastic, and an external thread is arranged on the outer wall of the connecting column 5.

[0022] The upper conductor 1 is provided with an insert hole 9, which is disposed on the bottom surface of the upper conductor 1. A copper sleeve 6 is installed in the insert hole 9, and the copper sleeve 6 and the insert hole 9 are integrally formed.

[0023] The copper sleeve 6 has a accommodating chamber 7, which is adapted to the annular protrusion 4. A snap-in slot 8 adapted to the connecting column 5 is opened on the accommodating chamber 7. The accommodating chamber 7 is connected to the snap-in slot 8. The diameter of the accommodating chamber 7 is larger than the diameter of the snap-in slot 8. An internal thread is installed on the inner wall of the snap-in slot 8.

[0024] Working principle: The connecting column 5 on the copper column 3 passes through the accommodating chamber 7 and extends into the snap-in slot 8, the internal thread and the external thread are spirally fixed, and the connecting column 5 is fixed to the snap-in slot 8, so that the copper column 3 is connected and fixed to the copper sleeve 6. At the same time, the annular protrusion 4 is engaged in the accommodating chamber 7 to better fix the copper column 3 and the copper sleeve 6, thereby fixing the upper conductor 1 and the lower conductor 2.

[0025] 1. The plug-in design does not require complicated welding processes, but only requires simple insertion and fixing operations, which greatly shortens the installation time of the busbar and significantly improves work efficiency, especially in large-scale production and on-site installation and maintenance.

[0027] 3: The copper column 3 and the copper sleeve 6 are tightly fixed by a special locking mechanism, which ensures good electrical contact and mechanical stability, and reduces safety hazards such as overheating and sparking caused by poor connection.

[0028] 4: The main body of the copper column 3 is made of high-strength, high-conductivity electrolytic copper material, and its surface is electroplated, which has excellent conductivity and extends service life.

[0029] Five: Due to the internal thread, external thread and elastic annular protrusion 4, the upper conductor 1 and the lower conductor 2 can be quickly and firmly fixed by screwing in or pressing. The plug-in and unplug parts are finely designed and the contact resistance is low, which is conducive to reducing losses and improving power transmission efficiency.
