[0021] Example

[0022] The utility model provides a compact and intensive bus duct, Figure 1-4 As shown, it includes a fixed shell 2 and a connecting shell 1 detachably arranged on the top thereof. The utility model simplifies the disassembly and assembly process of the bus duct by setting the fixed shell 2 and the connecting shell 1, improves the disassembly and assembly efficiency of the bus duct by the staff, and thus facilitates the staff to repair the bus duct.

[0023] The outer side walls of the fixed housing 2 and the connecting housing 1 are both coated with a flame retardant coating, and the flame retardant coating improves the flame retardancy of the bus duct.

[0024] refer to Figure 3 The fixed housing 2 shown in the figure includes a bottom plate 201 with a long rectangular structure. Baffles 202 are symmetrically provided on both sides of the top end surface of the bottom plate 201. The baffles 202 and the bottom plate 201 are integrally formed, thereby improving the overall strength of the fixed housing 2. A accommodating cavity 206 for placing the conductive bar 5 is formed between the two baffles 202. Conductive busbars 3 are provided on both sides of the conductive bar 5. A guide groove 203 with a trapezoidal structure is opened on the outer end surface of the baffle 202, and fastening grooves 207 are symmetrically opened on both sides of the top end surface of the baffle 202.

[0025] Furthermore, a snap-in groove 204 that matches the snap-in plate 105 is provided in the baffle 202. The snap-in groove 204 and the snap-in plate 105 cooperate with each other to improve the stability of the guide plate 102 when inserted into the guide groove 203. The snap-in groove 204 is connected to the guide groove 203.

[0026] Furthermore, a second fixed half-column 205 is provided on the outer end face of the baffle 202, which can be combined with the first fixed half-column 103 to form a fixed threaded column. The second fixed half-column 205 has the same structure as the first fixed half-column 103, and a fixing nut 4 is screwed on the fixed threaded column. The setting of the fixed threaded column formed by the fixing nut 4 in conjunction with the first fixed half-column 103 and the second fixed half-column 205 further improves the connection strength between the fixed shell 2 and the connecting shell 1.

[0027] refer to Figure 4 The connecting shell 1 shown in the figure includes a cover plate 104, and fastening columns 101 corresponding to the fastening grooves 207 are provided at the four corners of the bottom end surface of the cover plate 104. The arrangement of the fastening columns 101 and the fastening grooves 207 improves the stability of the connection between the fixed shell 2 and the connecting shell 1. Guide plates 102 adapted to the guide grooves 203 are symmetrically provided on both sides of the bottom end surface of the cover plate 104. The arrangement of the guide plates 102 and the guide grooves 203 improves the connection strength between the fixed shell 2 and the connecting shell 1. A clamping plate 1105 is provided at the bottom of the guide plate 102, and a plurality of evenly distributed first fixed semi-columns 103 are provided at the bottom of the outer end surface of the guide plate 102.

[0028] Furthermore, the height of the fastening column 101 is greater than the sum of the heights of the guide plate 102 and the clamping plate 105, so that when the fixed shell 2 and the connecting shell 1 are assembled, the fastening column 101 can play a guiding role, thereby facilitating the guided installation of the fixed shell 2 and the connecting shell 1.

[0029] The working principle of this utility model is as follows:

[0030] When inspecting the bus duct, first remove the fixing nut 4 on the fixing threaded column, move the connecting shell 1 upward to disconnect it from the fixed shell 2, so that the conductive bar 5 in the fixed shell 2 is exposed, so that it is convenient for the staff to inspect or replace the conductive bar 5. After the inspection is completed, press the connecting shell 1 on the top of the fixed shell 2, align the fastening column 101 on the connecting shell 1 with the fastening groove 207 on the baffle 202 and plug them in. In the process of plugging the fastening column 101 into the fastening groove 207, the conductive plate 101 on the connecting shell 1 is tightened. 2 is inserted into the guide groove 203 on the baffle 202. When the guide plate 102 is inserted into the bottom of the guide groove 203, the clamping plate 105 at the bottom of the guide plate 102 is inserted into the clamping groove 204, thereby connecting and installing the fixed housing 2 and the connecting housing 1, completing the assembly of the bus duct. At this time, the second fixed half column 205 on the fixed housing 2 and the first fixed half column 103 on the connecting housing 1 form a fixed thread column, and the fixing nut 4 is installed on the fixed thread column, thereby improving the connection strength between the fixed housing 2 and the connecting housing 1. The utility model simplifies the disassembly and assembly process of the bus duct by setting the fixed housing 2 and the connecting housing 1, improves the efficiency of the staff in disassembling and assembling the bus duct, and facilitates the staff to repair the bus duct.
