Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1: An integrated 90-degree adapter terminal, such as... Figure 1 , Figure 2 ,Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, it includes a connecting part 3, one end of which is integrally connected to a wiring part 1, and the other end is integrally connected to a cylindrical adapter part 2 for current transfer. The 90-degree adapter terminal of this application is constructed by sequentially and integrally forming the wiring part 1, the adapter part 3, and the cylindrical adapter part 2. The wiring part 1, the adapter part 2, and the connecting part 3 can be integrally formed using conventional stamping sheet metal processes. After integral forming, the connection between the wiring part 1, the adapter part 3, and the cylindrical adapter part 2 on the 90-degree adapter terminal is more robust, significantly improving connection reliability. Simultaneously, there is no interface transfer resistance, resulting in low cost. This solves the technical problem of poor connection reliability in existing 90-degree adapter terminals where the terminal body and the cylindrical connecting part are separate components.

[0039] The wiring section 1 can be expressed as a "U"-shaped structure, presenting as a crimping section 11, which connects to the cable through crimping; the wiring section 1 can also be expressed as a planar structure, presenting as a welding section 21, which connects to the cable through welding; the adapter section 2 is a cylindrical tubular body 31. When current is transferred using the radial inner surface 311 of the cylindrical tubular body 31, it can be expressed as a radial adapter section 30; when current is transferred using the axial end face 41 of the cylindrical tubular body 31, it can be expressed as an axial adapter section 40.

While there are commercially available 90-degree transition designs achieved through sheet metal rolling, this method is difficult to implement under high current conditions exceeding 250A due to material thickness limitations. The integral stretch forming process in this invention is less restricted by sheet metal thickness and can meet the requirements for current transmission conditions of at least 500A.

[0054] Example 10, based on Example 9, provides an integrated 90-degree adapter terminal, such as... Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the card holder structure 312 includes upper and lower parts arranged along the axial direction of the cylindrical transition part 2, and the two ends of the spring 32 respectively engage with the upper and lower parts of the card holder structure 312 for blocking.

[0055] As a design for a card holder structure 312, the upper and lower parts of the card holder structure 312 are an upper stop surface 318 and a lower stop surface 317, as follows: Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the upper stop surface 318 and the guide slope 319 are naturally formed at opposite positions on the radial inner circular surface 311. The cylindrical tubular body 31 of the radial transition part 30 mates with the spring 32 within the radial inner circular surface 311. A guide radius 313 is provided on one side of the cylindrical tubular body 31's carrier plate, and the spring 32 is guided into the inner cavity formed by the radial inner circular surface 311 through its guide radius. When the head of the spring 32 is inserted into the radial inner circular surface, it first contacts the guide slope 319, and then slides across the slope. The tail of the spring 32 contacts the planar structure of the upper stop surface 318 for positioning. The cylindrical tubular body 31 contracts towards the center on the radial inner circular surface opposite to the carrier plate, forming a coaxial stepped cylindrical structure 3190 at the bottom. The stepped cylinder 3190 is provided with a lower stop surface 317 perpendicular to the radial inner circular surface 311 and a guide angle 316. The lower stop surface 317 stops the spring sheet 32 ​​in the installation direction. At least three recessed wedge-shaped structures with equal height in the axial direction and evenly arranged in the axial direction are formed on the outer surface of the cylindrical tubular body 31 of the cylindrical transition part 2. The part of the wedge-shaped structure extending into the radial inner circular surface forms the upper stop surface 318 of the mounting structure 312. The recessed wedge-shaped structure can be formed by stamping.

[0056] As a design for a card holder structure 312, the upper and lower parts of the card holder structure 312 are an upper stop surface 318 and a lower stop surface 317, as follows:Figure 9 As shown, a cylindrical inner groove 3191 can be added inside the radial inner surface 311. This cylindrical inner groove 3191 structure can be realized by local machining. The above-mentioned cylindrical inner groove 3191 structure forms an upper stop surface 318 at one end to limit and stop the spring 32; and forms a lower stop surface 317 at the other end to limit and stop the other end of the spring 32.

[0057] As a solution for the card holder structure 312, a pressure cap 33 can be added to cooperate with the radial transition part 30 to limit and stop the spring 32, such as... Figure 10 and Figure 11 As shown, the upper and lower parts of the card holder structure 312 are an upper stop surface 318 and a pressure cover 33. The spring 32 is located within the radial inner circular surface 311 of the cylindrical transition part 2. One end of the radial inner circular surface 311 is connected to the pressure cover 33, and the other end is provided with the upper stop surface 318. The pressure cover 33 is a rotating body composed of a long side 332 and a short side 333. The upper stop surface 318 and the short side 333 of the pressure cover 33 respectively stop and cooperate with the two ends of the spring 32. The pressure cover 33 has a rotating body composed of a long side 332 and a short side 333. One end of the cylindrical tubular body III31c of the radial transition part 30 has a circumferentially concave riveting groove 331. The other end of the cylindrical tubular body III31c is connected to the carrier plate.

[0058] The connection between the pressure cap 33 and the cylindrical transition part 2 is as follows: Figure 11 As shown, the radial inner circular surface 311 forms a cylindrical inner groove 3191 at one end of the pressure cap; one end of the cylindrical inner groove 3191 forms an upper stop surface 318 to limit and stop the spring 32; at the other end, it forms a stop groove 334 with the short side 332 of the pressure cap 33, and the stop groove 334 limits and stops the other end of the spring 32; the pressure cap 33 is riveted to the riveting groove 331 by the structure of the long side 332, providing the pressure cap 33 with the holding force of the cylindrical tubular body III31c, thereby preventing the spring 32 from dislodging; the spring 32 is placed into the inner cavity formed by the cylindrical inner groove 3191 before the pressure cap 33 is installed; the riveting groove 331 and the cylindrical inner groove can be realized by local machining.

[0059] In Example 10, taking a 90-degree radial adapter terminal as an example, the wiring part 1, the connecting part 3, and the adapter part 2 are integrally formed by stamping sheet metal process. Then, the spring 32 is installed into the radial adapter part 30. The spring 32 is clamped and arranged in the radial inner circle 311 of the cylindrical tube 31, thus forming the 90-degree radial adapter terminal of this application. When other terminals are inserted into the 90-degree radial adapter terminal of this application, the other terminals are inserted into the cylindrical tube 31 and contact the spring 32. After the other terminals contact the spring 32, they are fixed by the pre-tightening force of the spring 32 to complete the radial current transfer.
