Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a convenient photovoltaic and household splicing busbar system. Background Art

[0002] The busbar is an important component in the electrical field. At present, spliced busbars are mostly used in medium and large equipment such as distribution rooms, and small household distribution boxes mostly use a busbar system with a fixed layout (fixed terminal spacing). A general household distribution box will have a variety of switches (such as 1P, 1P+N, 2P, 3P, 3P+N, 4P switches, etc.). When users need to use multiple types of switches together, the existing fixed layout cannot meet the diverse needs of users, resulting in the fixed arrangement of the busbar system. The use scenario is relatively limited and single, and it can only support a single row of switches with consistent structural specifications. Most household distribution boxes today still use wire connection methods, which are messy and complicated, and prone to loose connections. Summary of the Invention

[0025] Through the free connection combination of the wiring terminals 1, the wiring terminal connection row 2, and the connecting busbar 3, the spacing between the wiring terminals 1 can be freely adjusted, which is practical and convenient, and the wiring is simple. It is also insulated and protected by the insulating protection component 4, which has high safety, making the wiring operation of a small household distribution box simpler and more convenient. At the same time, the wiring is firm and it is not easy to have the problem of loose connection and heating, thereby reducing the fire hazard of the distribution box.

[0026] Furthermore, the insulation protection assembly 4 includes an insulation sheath 41 sleeved on the busbar, and an insulation seal 42 that can be installed and embedded in the open end of the insulation sheath 41.

[0027] An insulating buckle cover 43 is inserted on one end of the outer side of the insulating sheath 41 .

[0028] like Figure 2 As shown, in this embodiment, during installation, after connecting the connecting busbar 3, the terminal connection bar 2 and one end of the connecting terminal 1, the slots on the insulating sheath 41 are correspondingly inserted into the busbar line, and then the insulating seal 42 is correspondingly installed and embedded in the open end of the insulating sheath 41, and finally the insulating buckle cover 43 is correspondingly inserted into the outer end of the insulating sheath 41 to complete the wiring assembly, which is practical and convenient.

[0029] Furthermore, the insulating sheath 41 includes one or more of a first insulating sheath 41-1, a second insulating sheath 41-2, a third insulating sheath 41-3 or a fourth insulating sheath 41-4.

[0035] Specifically, if Figure 3 As shown, the elbow connector 5 includes either a male-female elbow connector or a female-female elbow connector. The one on the left in the figure is a male-female elbow connector, with male and female ends on either side. The one on the right in the figure is an female-female elbow connector, with both ends being female. During assembly, either male-female or female-female elbow connector can be selected based on specific connection requirements, providing practicality and convenience.

[0036] Furthermore, the materials of the connecting terminal 1, the terminal block connecting bar 2, the connecting busbar 3 and the turning joint 5 are all one or more of copper, tinned copper and red copper.

[0037] Specifically, the connection and assembly process of the embodiment of the present application is as follows:

[0038] First, according to the needs of the user, the position of the terminal block 1 can be freely arranged, and then according to the position of the arranged terminal block 1, the specific spacing value can be measured, and the terminal block connection row 2 of appropriate length can be cut out. Then, according to the length value of the terminal block connection row 2 and the number of terminal blocks 1, the required value of the connection busbar 3 can be measured and calculated, and the connection busbar 3 of appropriate length can be cut out according to the required value. Then, the terminal block 1, the terminal block connection row 2 and the connection busbar 3 can be spliced. At this time, if multiple rows are required, the turning joint 5 can be added for splicing. Finally, the insulation protection component 4 and the auxiliary insulation protection component 6 are put on to press and fix them to achieve insulation and complete the assembly.
