Description

Technical Field

[0001] This utility model relates to the field of energy storage connector technology, and in particular to an energy storage connector terminal. Background Technology

[0002] In electronic devices, electrical connectors are typically used to achieve electrical connections between electrically independent components. Electrical connectors enable electrical conduction between two independent electrical structures. Energy storage connectors are a common type of electrical connector, usually used for high-current connections. Energy storage connectors are generally mating connectors, consisting of a board-end socket fixed to the device housing and a wire-end plug that mates with the board-end socket. Electrical connection is achieved when the wire-end plug is inserted into the board-end socket.

[0003] Existing energy storage connectors have plug terminals consisting of a crimping end and a connecting end. Current technology typically involves punching mounting holes on the crimping end and then riveting it to the connecting end conductor. This riveting connection increases resistance and poses a risk of detachment. Furthermore, the connecting end conductor is machined to form an internal socket, requiring a spring clip to secure the conductor. This spring clip not only increases material costs but also adds to the production process, impacting efficiency. Utility Model Content

[0023] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0024] Please refer to Figure 1 and Figure 2 An energy storage connector terminal includes a crimping end 1, a bending portion 2, and a connecting end 3 connected in sequence. The crimping end 1, the bending portion 2, and the connecting end 3 are integrally formed. The connecting end 3 includes a connecting conductor 31 and a plurality of contact arms 32. One end of the connecting conductor 31 is connected to the bending portion 2, and the plurality of contact arms 32 are respectively connected to the end of the connecting conductor 31 away from the bending portion 2.

[0025] As can be seen from the above description, the beneficial effects of this utility model are as follows: the energy storage connector terminal is integrally formed by the pressure end 1, the bending part 2 and the connecting end 3, which effectively reduces the overall resistance of the terminal, avoids the risk of component separation, thereby improving the service life, and the integrated structure can also reduce production steps, thereby improving production efficiency and reducing production costs.

[0026] Furthermore, the pressure end 1 is an open ring shape.

[0027] As can be seen from the above description, the wire end 1 can be formed by bending process, which has high production efficiency and can ensure a large contact and conduction area.

[0028] Furthermore, the connecting conductor 31 is an open ring.

[0029] As can be seen from the above description, the connecting conductor 31 can be formed by bending process, which has high production efficiency.

[0030] Furthermore, the cross-sections of the wire end 1, the bending part 2, and the connecting conductor 31 are all arc-shaped.

[0031] As can be seen from the above description, the arc-shaped wire end 1 can make large-area contact with the cable, and the arc-shaped connecting conductor 31 facilitates plugging and mating with the socket conductor within a wider angle range.

[0032] Furthermore, the contact arm 32 includes a connecting section 321 and a contact section 322. The contact section 322 is connected to the connecting conductor 31 through the connecting section 321, and the contact section 322 is bent and protrudes inward.

[0033] As described above, the inward bending and protrusion of contact section 322 facilitates close contact with the socket conductor, preventing accidental disconnection between the plug and socket of the energy storage connector.

[0034] Furthermore, the contact arm 32 also includes an outwardly turned portion 323, which is formed by bending and extending the contact segment 322 outwardly from the end away from the connecting segment 321.

[0035] As described above, the outward-curving part 323 can serve as a guide, facilitating the insertion of the socket conductor between multiple contact arms 32.

[0036] Furthermore, the width of the outwardly turned portion 323 gradually increases from one end near the contact section 322 to the other end.

[0037] As can be seen from the above description, increasing the width of the end of the outward-facing portion 323 that is away from the contact section 322 is beneficial to improving the guiding performance of the outward-facing portion 323 and further reducing the difficulty of inserting the socket conductor between multiple contact arms 32.

[0038] Furthermore, it also includes an auxiliary sleeve 4, which is arranged around multiple contact arms 32.

[0039] As described above, the auxiliary sleeve 4 can apply an inward squeezing force to the multiple contact arms 32, thereby increasing the insertion and extraction force between the plug and the socket, so that the contact arms 32 can make closer contact with the socket conductor.

[0040] Furthermore, the auxiliary sleeve 4 is an open ring.

[0041] As can be seen from the above description, designing the auxiliary sleeve 4 as an open ring can appropriately enlarge the auxiliary sleeve 4 during assembly, thereby making it convenient for the auxiliary sleeve 4 to be fitted over the connecting end 3.

[0042] Furthermore, the auxiliary sleeve 4 is made of metal or plastic.

[0043] Please refer to Figure 1 and Figure 2 One embodiment of this utility model is as follows: an energy storage connector terminal includes a wire clamping end 1, a bent portion 2, and a connecting end 3 connected in sequence. The wire clamping end 1, the bent portion 2, and the connecting end 3 are integrally formed. The connecting end 3 includes a connecting conductor 31 and multiple contact arms 32. One end of the connecting conductor 31 is connected to the bent portion 2, and the multiple contact arms 32 are respectively connected to the end of the connecting conductor 31 away from the bent portion 2. Specifically, the wire clamping end 1, the bent portion 2, and the connecting end 3 are made of copper, and the extension direction of the wire clamping end 1 is perpendicular to the extension direction of the connecting end 3. In other embodiments, the wire clamping end 1, the bent portion 2, and the connecting end 3 can be made of other conductive materials, including but not limited to steel or gold; it is also feasible for the extension direction of the wire clamping end 1 to form an acute or obtuse angle with the extension direction of the connecting end 3.

[0044] The wire end 1 is an open ring shape, including a first main body 11 and first extensions 12 connected to both sides of the first main body 11. The connecting conductor 31 is an open ring shape, including a second main body 311 and second extensions 312 connected to both sides of the second main body 311. Contact arms 32 are respectively provided on the second main body 311 and the second extensions 312. The first main body 11 of the wire end 1 and the second main body 311 of the connecting conductor 31 are connected by a bending portion 2. The wire end 1, the bending portion 2, and the connecting end 3 are formed from the same metal plate through a bending process. In this embodiment, the cross-sections of the wire end 1, the bending portion 2, and the connecting end 3 are all arc-shaped, and the axial direction of the contact arm 32 is collinear with the axial direction of the connecting conductor 31 (the axial direction of the wire end 1 is the extension direction of the wire end 1, and the axial direction of the connecting end 3 is the extension direction of the connecting end 3). Multiple contact arms 32 are evenly distributed around the circumference of the connecting conductor 31.

[0045] In other embodiments, the wire end 1, the bending portion 2, or the connecting conductor 31 can be configured as other open ring shapes, such as a polygonal ring or an elliptical ring with an opening; it is also feasible for the first extension 12 to be connected to the connecting conductor 31 through the bending portion 2 or for the second extension 312 to be connected to the wire end 1 through the bending portion 2.

[0046] The contact arm 32 includes a connecting section 321 and a contact section 322. The contact section 322 is connected to the connecting conductor 31 through the connecting section 321, and the contact section 322 is bent and protrudes inward.

[0047] The contact arm 32 also includes an outwardly flared portion 323, which is formed by bending and extending outward from the end of the contact segment 322 away from the connecting segment 321. The width of the outwardly flared portion 323 gradually increases from the end closer to the contact segment 322 to the other end.

[0048] The energy storage connector terminal also includes an auxiliary sleeve 4, which surrounds multiple contact arms 32. In this embodiment, the auxiliary sleeve 4 is shaped as an open ring corresponding to the connecting end 3. The auxiliary sleeve 4 is fitted over the contact segments 322 of the multiple contact arms 32. Because the contact segments 322 are bent inwards and protrude, a concave groove is formed on the outer side of the contact segments 322. The auxiliary sleeve 4 is positioned within this groove, reducing the risk of separation between the auxiliary sleeve 4 and the connecting end 3. The auxiliary sleeve 4 is made of steel. In other embodiments, when the connecting end 3 is shaped as another open ring, such as a polygonal or elliptical ring with an opening, the shape of the auxiliary sleeve 4 matches the shape of the connecting end 3; the auxiliary sleeve 4 can be made of other metals such as copper; the auxiliary sleeve 4 can also be made of plastic.

[0049] In summary, the energy storage connector terminal provided by this utility model effectively reduces the overall resistance of the terminal by integrally molding the crimping end, bending portion, and connecting end, avoiding the risk of component separation and thus extending its service life. Furthermore, the integrated structure reduces production steps, thereby improving production efficiency and reducing production costs. Adding auxiliary sleeves to the multiple contact arms applies inward compressive force to the contact arms, thereby increasing the insertion and extraction force between the plug and socket, allowing the contact arms to make tighter contact with the socket conductor.

[0050] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
