[0015] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0016] The utility model discloses a motor terminal with reliable connection, combined with Figures 2 to 4 As shown, it includes a hard connection part 1 and the soft connection part 2, the end of the hard connection part 1 is provided with a mortise 10, the end of the soft connection part 2 is formed with a tenon 20, the tenon 20 is arranged in the mortise 10 and the two are engaged with each other, and the tenon 20 and the mortise 10 are welded and fixed.

[0017] In the above structure, the hard connection part 1 and the soft connection part 2 are first prepared and formed separately, and a mortise 10 is set at the end of the hard connection part 1, and correspondingly, a tenon 20 is set at the end of the soft connection part 2, and the tenon 20 and the tenon 10 are inserted into each other and then welded and fixed. Based on the mutual matching of the tenon 20 and the tenon 10, the utility model can enhance the connection strength between the hard connection part 1 and the soft connection part 2, and then tightly connect them by welding. Compared with the large-area welding method in the prior art, the utility model is not only easy to manufacture and save costs, but also can achieve reliable connection, and better meet the application requirements.

[0018] As a preferred embodiment, the mortise 10 is a dovetail mortise, and the tenon 20 is a dovetail tenon. However, this is only a preferred matching method of the present invention. In practical applications, other shapes of structures can also be used, and these replacement solutions all belong to the protection scope of the present invention.

[0019] Furthermore, the tenon 20 is fixed to the tenon groove 10 by laser welding. In practical applications, the soft connection part 2 is formed by polymer diffusion welding, and the soft and hard terminal connection parts are connected by laser welding technology. The laser welding technology is mature and can better meet the functional requirements of the product.

[0020] Specifically, the flexible connection portion 2 is formed by stacking multiple layers of sheets.

[0021] In order to facilitate the arrangement of the terminals, in the present embodiment, the end of the hard connection portion 1 is bent to form a bent portion 11 , and the tongue and groove 10 is disposed on the bent portion 11 .

[0022] The reliably connected motor terminal disclosed by the utility model is applied to new energy vehicles as a power connection terminal for a motor and an electronic control. The terminal is made of T2 copper. The utility model makes the soft connection part into a soft terminal structure composed of multiple layers of soft copper foil, and then dovetails the soft and hard connection terminals, and finally connects them into a whole by laser welding. Not only is the connection relationship more reliable, but it is also conducive to mass production and saves manufacturing costs.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
