Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings.

[0035] like Figures 1 to 5As shown, this utility model provides a multi-hole plug-in terminal block, including a housing 1 and a mounting cavity 11 disposed within the housing 1. A conductive contact is assembled within the mounting cavity 11. The conductive contact mainly consists of a busbar 2 and a plug-in portion 4 integrally formed with the busbar 2. Several sets of wiring portions 3 are formed on the busbar 2, and the multiple wiring portions 3 are arranged in parallel. The housing 1 has several through holes 18 corresponding to the wiring portions 3, and plug-in holes 17 corresponding to the plug-in portions 4, so that wires or plug-in components can smoothly enter and complete the electrical connection.

[0036] like Figure 2 and Figure 3 As shown, the busbar 2 is composed of a first conductive sheet 21 and a second conductive sheet 22 arranged in parallel, which are connected by a bending part 23, thereby forming a stable parallel frame in structure. The bending part 23 not only ensures the overall integrity between the conductive sheets, but also enhances the mechanical strength of the busbar 2, ensuring that the current can be reliably conducted between the first conductive sheet 21 and the second conductive sheet 22. The wiring part 3 includes a wiring clip integrally formed in the busbar 2. The wiring clip is composed of a first clip 31 and a second clip 32. The fixed end of the first clip 31 is connected to the first conductive sheet 21, and the fixed end of the second clip 32 is connected to the second conductive sheet 22. The free ends of the two are close to each other to form a wiring gap. In use, the wire is inserted into the wiring gap through the wire hole 18 of the housing 1. Under the elastic clamping action of the first clip 31 and the second clip 32, the wire is in close contact with the wiring clip, thereby forming a reliable electrical connection.

[0037] like Figures 2 to 4 As shown, the insertion part 4 is composed of a clamping connecting piece integrally formed on the busbar 2. The clamping connecting piece includes a first clamping connecting piece 41 and a second clamping connecting piece 42, which are fixedly connected to the first conductive piece 21 and the second conductive piece 22, respectively. At the end away from the busbar 2, the end of the clamping connecting piece is tapered inward to form an insertion gap. The external conductive plug can enter the insertion gap through the insertion hole 17 of the housing 1 and is fixed by the clamping force of the first clamping connecting piece 41 and the second clamping connecting piece 42 to prevent loosening. The connecting piece consists of a connecting part 43 and a guiding part 44, with a clamping part 45 disposed between them. The inner sidewall of the connecting part 43 is bent to form a first clamping piece 411 and a second clamping piece 421, which form a clamping gap. This clamping gap is on the same straight line as the insertion gap. When an external conductive plug is inserted, it will be guided by the guiding part 44 and enter the clamping gap. At the same time, it will be clamped by the bidirectional clamping action of the first clamping piece 411 and the second clamping piece 421, which further improves the stability and reliability of the insertion.

[0038] like Figure 2 and Figure 3As shown, several sets of support and positioning structures are provided between the first conductive sheet 21 and the second conductive sheet 22, which can effectively support the conductive sheet when subjected to force and prevent it from bending and deforming. The busbar 2 includes a first side 24 and a second side 25 arranged perpendicularly to each other. The two constitute the first support and positioning structure and the second support and positioning structure, respectively, supporting the busbar 2 from two positions, making the overall structure more stable.

[0039] The first side portion 24 is composed of a first snap-fit ​​piece 241 integrally formed on the first conductive sheet 21 and a second snap-fit ​​piece 242 integrally formed on the second conductive sheet 22. The first snap-fit ​​piece 241 is provided with a first buckle 2411, and the second snap-fit ​​piece 242 is provided with a first slot 2421. The two are fixed by snap-fit ​​engagement. The second side portion 25 is composed of a third snap-fit ​​piece 251 and a fourth snap-fit ​​piece 252. The second snap-fit ​​piece 251 and the second slot 2521 are also used for positioning to ensure a reliable connection between the first conductive sheet 21 and the second conductive sheet 22 and to avoid loosening and misalignment caused by external force or vibration. The first side portion 24 is located between two adjacent sets of wiring portions 3 to ensure the stability of the wiring of the wiring portion 3.

[0040] like Figures 1 to 3 As shown, a limiting block 12 is provided on the inner wall of the mounting cavity 11, which is engaged with the limiting groove 231 on the bending part 23 of the busbar 2. Through the cooperation of the limiting block 12 and the limiting groove 231, the position of the conductive contact in the housing 1 can be effectively restricted, avoiding displacement of the conductive contact due to vibration, and ensuring the overall stability of the wiring terminal.

[0041] like Figure 4 As shown, a mounting post 13 is provided at the end of the housing 1 facing the opening of the mounting cavity 11, and a mounting hole 14 is provided on the end face of the housing 1 away from the mounting cavity 11. When multiple terminals are in use, they can be inserted into the mounting holes 14 of adjacent housings through the mounting post 13, thereby realizing modular splicing. In addition, a locking protrusion 15 is provided on the opening end face of the housing 1. The outer side of the locking protrusion 15 forms an inverted buckle 151 structure. A locking groove 16 is provided on the end face of the housing 1 away from the mounting cavity 11. After the locking protrusion 15 is inserted into the locking groove 16, the inverted buckle 151 and the outer periphery of the locking groove 16 form a snap-fit ​​engagement, so that multiple terminals can remain stable under the action of external force after splicing, avoiding the problem of loosening or separation.

[0042] The basic working principle of this utility model is as follows: First, multiple terminals are combined. The mounting post 13 of an adjacent housing 1 is inserted into the mounting hole 14 of another housing 1, and the terminals are spliced ​​together by snapping the buckle 151 with the outer periphery of the locking groove 16. Then, the conductive plug is inserted into the plug part 4 through the plug hole 17. The conductive plug is guided by the guide part 44 and enters the clamping gap. The first clamping connecting piece 41 and the second clamping connecting piece 42 tightly clamp the conductive plug. Then, the wire is fed in through the wire hole 18 of the terminal housing 1. When the front end of the wire enters one of the wiring parts 3, the wire is pushed to fully enter the wiring gap and be clamped by the first clamping piece 31 and the second clamping piece 32. If necessary, another wire can be fed into another set of wiring parts 3 so that the two wires can be electrically connected respectively.

[0043] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
