Description

Technical Field

[0001] This utility model relates to the field of electrical transmission technology, and more specifically to a terminal. Background Technology

[0002] With the development of the new energy vehicle industry, many electrical circuits in electric vehicles require terminal connections. Currently, clamping terminals are commonly used to hold flat terminals together. These clamping terminals rely on their own elasticity to apply a holding force to the flat terminals. However, insufficient clamping force often leads to separation, or the actual contact area between the terminals and the flat terminals decreases, increasing resistance and causing excessive heat generation. This rapid temperature rise, especially during high-voltage charging, can easily lead to accidents that endanger life and property. Using additional parts to secure the clamping terminals increases costs and complicates the installation process. Therefore, a new solution is urgently needed to address these problems. Utility Model Content

[0003] To solve the above problems, this utility model proposes a terminal for clamping and electrically connecting plug-in terminals, as well as for electrically connecting to cables. It includes a clamping part and a connecting part. The clamping part includes two oppositely arranged spring pieces with one end connected to the connecting part. The distance between the two spring pieces gradually decreases from the fixed end to the free end, then gradually increases after they come together. A reinforcing rib is provided on the spring piece along the extension direction of the spring piece, and at least one auxiliary rib is provided on the side of the reinforcing rib and protrudes along the direction perpendicular to the extension direction of the spring piece.

[0004] The spring sheet includes a connecting section, an abutting section, and a receiving section connected in sequence. The receiving section is connected to the connecting part. The abutting sections of the two spring sheets at least partially abut each other. The reinforcing rib is located at least on the abutting section and the receiving section.

[0005] The accommodating section is perpendicular to the connecting portion, and the connection between the accommodating section and the connecting portion forms a first transition section with a smooth transition.

[0006] The reinforcing rib extends to the first transition section, and a first auxiliary rib is provided at least on the first transition section.

[0007] The receiving section includes a straight section and a bent section that gradually approaches the center line of the two spring pieces, with a smooth transition at the connection between the straight section and the bent section to form a second transition section.

[0008] At least one second auxiliary reinforcement shall be provided on the second transition section.

[0009] Multiple second auxiliary ribs are provided at intervals on the straight segment and the bent segment.

[0010] The first auxiliary rib and the second auxiliary rib are arranged in pairs and are located on both sides of the reinforcing rib.

[0011] The spring sheet and the connecting part are integrally formed, and the reinforcing rib and the auxiliary rib are protruding structures formed by stamping on the spring sheet.

[0012] At least one connecting segment for connecting to the cable is provided on the connecting part.

[0013] The beneficial effects provided by this utility model are as follows: The two spring pieces of the clamping part are arranged opposite each other to clamp the mating terminals. The middle parts of the two spring pieces are close to each other to better apply clamping force to the mating terminals. The reinforcing ribs protrude from the spring pieces, thereby greatly increasing the strength of the spring pieces and providing a stronger clamping force. The auxiliary ribs can assist the reinforcing ribs, which can not only further increase the clamping force of the clamping part, but also prevent the spring pieces from expanding outward and causing irreversible bending after the mating terminals are inserted.

[0022] The preferred embodiments of this disclosure are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure. Furthermore, the embodiments and features in the embodiments of this disclosure can be combined with each other without conflict.

[0023] A terminal for clamping and electrically connecting mating terminals, and for electrically connecting to cables, such as... Figure 1 and Figure 2 As shown, it includes a clamping part 1 and a connecting part 2. The clamping part 1 includes two oppositely arranged spring pieces 11 connected to the connecting part 2 at one end. The distance between the two spring pieces 11 gradually decreases from the fixed end to the free end, and then gradually increases after they fit together. A reinforcing rib 3 is provided on the spring piece 11 along the extension direction of the spring piece 11, and at least one auxiliary rib 4 is provided on the side of the reinforcing rib 3 and protrudes along the direction perpendicular to the extension direction of the spring piece.

[0024] The clamping part 1 is used to clamp the mating terminals, and the connecting part 2 is used to connect the cable. Two spring pieces 11 of the clamping part 1 are arranged opposite each other to clamp the mating terminals. The middle portions of the two spring pieces 11 are close to each other to better apply clamping force to the mating terminals. A reinforcing rib 3 protrudes from the spring piece 11, thereby significantly increasing the strength of the spring piece 11 and providing a stronger clamping force. An auxiliary rib 4 assists the reinforcing rib 3, not only further increasing the clamping force of the clamping part 1 but also preventing the spring piece 11 from expanding outwards and causing irreversible bending after the mating terminals are inserted.

[0025] In some embodiments, the spring 11 includes a connecting section 111, an abutting section 112, and a receiving section 113 connected in sequence. The receiving section 113 is connected to the connecting portion 1. The abutting sections 112 of the two springs 11 at least partially abut against each other. The reinforcing rib 3 is located at least on the abutting section 112 and the receiving section 113. The connecting section 111 is used for inserting a mating terminal, the abutting section 112 is used to clamp the mating terminal, and the end of the mating terminal is located between the two receiving sections 113.

[0026] In some embodiments, the accommodating segment 113 is partially perpendicular to the connecting portion 2, and the connection between the accommodating segment 113 and the connecting portion 2 forms a first transition segment 21 with a smooth transition.

[0027] Furthermore, the reinforcing rib 3 extends to the first transition section 21, and a first auxiliary rib 41 is provided at least on the first transition section 21. The reinforcing rib 3 extending to the first transition section 21 can improve the overall strength of the spring piece 11, and the first auxiliary rib 41 can improve the connection strength between the spring piece 11 and the connecting part 2.

[0028] In some embodiments, the receiving segment 113 includes a straight segment 1131 and a bent segment 1132 that gradually approaches the center line of the two spring pieces 11, and the connection between the straight segment 1131 and the bent segment 1132 forms a smooth transition segment 1133.

[0029] Furthermore, at least one second auxiliary rib 42 is provided on the second transition section 1133. The second auxiliary rib 42 can reinforce the second transition section 1133 and prevent the spring piece 11 from undergoing irreversible deformation when the mating terminal is inserted.

[0030] In some embodiments, a plurality of second auxiliary ribs 42 are provided at intervals on the straight segment 1131 and the bent segment 1132. The plurality of second auxiliary ribs 1133 work together to increase the strength of the spring sheet 11.

[0031] In some embodiments, the first auxiliary rib 41 and the second auxiliary rib 42 are arranged in pairs and located on both sides of the reinforcing rib 3. The paired arrangement of the first auxiliary rib 41 and the second auxiliary rib 42 ensures that the strength of the spring piece 11 is comparable at all points, making it less prone to deformation and providing better elasticity.

[0032] In some embodiments, the spring piece 11 and the connecting portion 2 are integrally formed, and the reinforcing rib 3 and the auxiliary rib 4 are protruding structures stamped on the spring piece 11. This integral forming design not only simplifies the process and reduces costs, but also reduces connection points, lowers resistance, and improves electrical transmission efficiency.

[0033] In some embodiments, at least one connecting segment 22 for connecting to the cable extends from the connecting portion 2. The connecting segment 22 can be connected to the cable by welding, screwing, riveting, or other methods.
