Description

Technical Field

[0001] The present invention relates to a connector assembly terminal, including a connector of the connector assembly terminal and a connector assembly including the connector. Background Technology

[0002] In existing technology, connectors typically include a housing and terminals disposed within the housing. Each terminal includes a pair of separate, elastic arms for holding a bus inserted between them to achieve an electrical connection between the terminal and the bus. Existing terminals are typically single-layered with only one pair of electrical contacts, which limits their current-carrying capacity, preventing them from carrying higher currents, for example, 500A or higher. To improve current-carrying capacity, existing technology can only increase the size of the terminals, which is detrimental to connector miniaturization. Summary of the Invention

[0057] like Figures 1 to 11 As shown in the illustrated embodiment, the slot 17a on the connecting ear 17 is a U-shaped hole with an open outer side. An opening 108 for accommodating the head 18a of the bolt 18 is formed at the bottom of the first cantilever 10 and the second cantilever 20, and the connecting ear 17 is located in the opening 108.

One end of the V-shaped elastic arm 23 is connected to the upper end of the second tilting arm 22. The end of the V-shaped elastic arm 23 is used for electrical contact with the first busbar 300.

[0061] like Figures 1 to 11 As shown in the illustrated embodiment, the second lower spring arm 21 and the second tilting arm 22 are respectively stacked inside the first lower spring arm 11 and the first tilting arm 12 and are adapted to abut against the inside of the first lower spring arm 11 and the first tilting arm 12 respectively.

[0062] like Figures 1 to 11 As shown in the illustrated embodiment, the distance between the upper ends of the second tilting arms 22 of the pair of second cantilever 20 is smaller than the distance between the lower ends of the second tilting arms 22 of the pair of second cantilever 20. The distance between the ends of the pair of second cantilever 20 is slightly smaller than the thickness of the first busbar 300 so that it can make simultaneous electrical contact with both sides of the first busbar 300 inserted between them.

[0063] like Figures 1 to 11 As shown in the illustrated embodiment, the V-shaped elastic arm 23 includes a fixing plate 230, a second elastic arm 231, and a second guide arm 232. The fixing plate 230 is fixed to the inner side of the upper end of the second inclined arm 22. The second elastic arm 231 is connected to the fixing plate 230 and extends downward.

[0064] like Figures 1 to 11 As shown in the illustrated embodiment, the end of the second guide arm 232 is bent into an arc shape to serve as a second electrical contact portion 25 that makes electrical contact with the first busbar 300.

[0065] like Figures 1 to 11 As shown in the illustrated embodiment, the second base plate 26, the second lower spring arm 21, and the second tilting arm 22 of the second terminal 2 are formed as a single piece, and the V-shaped elastic arm 23 is a single stamped part.

[0066] like Figures 1 to 11 As shown in the illustrated embodiment, multiple second partition slits 2b are formed on the second guide arm 232, and the multiple second partition slits 2b are spaced apart along the length Y direction of the second base plate 26.

Figure 12 and Figure 13 The connector combination terminals shown are Figures 1 to 11The only difference between the connector combination terminals shown is the structure in which the first cantilever 10 makes electrical contact with the first busbar 200. Figure 12 and Figure 13 Other technical features of the connector combination terminals shown are similar to Figures 1 to 11 The connector terminal combinations shown are basically the same and can be used as a reference. Figures 1 to 11 The connector assembly terminals are shown.

[0068] like Figure 12 and Figure 13 As shown in the illustrated embodiment, a plurality of contact protrusions 19 are formed on the end of the first guide arm 14.

Figure 12 and Figure 13 The contact protrusion 19 shown is Figures 1 to 11 Compared to the arc-shaped first electrical contact 15, the contact protrusion 19 has the following advantages: It occupies less space, making it easier to adjust the distance between the electrical contact points of the first cantilever 10 and the second cantilever 20. The smaller this distance, the smaller the gold-plated area on the first busbar 200 for electrical contact with the connector assembly terminal, resulting in lower costs. For the connector assembly terminal, only gold plating is required on the contact protrusion 19, requiring less plating material and reducing costs. Furthermore, the contact protrusion 19 uses less material and is more cost-effective than the arc-shaped first electrical contact 15.

[0069] like Figures 1 to 13 As shown, in another exemplary embodiment of the invention, a connector is also disclosed. The connector includes an insulating shell 3 and the aforementioned connector combination terminals.

The connector combination terminals are mounted in the insulating shell 3 via the bottom opening 302. The first terminal 1 and the second terminal 2 of the connector combination terminals are adapted to simultaneously clamp a first busbar 300 inserted via the top socket 301.

[0070] like Figures 1 to 13 As shown in the illustrated embodiment, the insulating shell 3 includes a sidewall 31 that forms an inner cavity and a connecting beam 32 that is connected to the bottom of the sidewall 31. The connecting beam 32 extends along the length direction Y of the second base plate 26 of the second terminal 2 and abuts against the top surface of the second base plate 16 of the second terminal 2.
