[0033] The utility model provides a kind of terminal structure to simplify terminal structure, and then improve the versatility of terminal structure.

[0034] Referring to FIG. 1, in an embodiment, the terminal structure includes a conductive plate 100, an upper conductive elastic arm 210, and a lower conductive elastic arm 220. One end of the upper conductive elastic arm 210 is connected to the conductive plate 100, and one end of the lower conductive elastic arm 220 is connected to the conductive plate 100. The upper conductive elastic arm 210 and the lower conductive elastic arm 220 are integrally formed with the conductive plate 100, and the end of the upper conductive elastic arm 210 away from the conductive plate 100 and the end of the lower conductive elastic arm 220 away from the conductive plate 100 can be close to or away from each other.

[0035] The conductive plate 100 is mainly used to connect with an electronic device to transmit current to the electronic device. In an embodiment, the conductive plate 100 is provided with a connecting hole 110 to facilitate connection with the electronic device through the connecting hole 110. In an embodiment, the connecting hole 110 can be a threaded hole or a pin hole to facilitate connection with the electronic device through a bolt or a pin. Here, the specific form of the connecting hole 110 is not limited. Of course, in other embodiments, the conductive plate 100 can also be connected to the electronic device by welding or clamping, etc., which is not limited here. In an embodiment, only one conductive plate 100 is provided in the terminal structure to simplify the overall structure. The shape and size of the conductive plate 100 can be flexibly set according to actual needs, which is not limited here.

[0036] The upper conductive elastic arm 210 and the lower conductive elastic arm 220 are located on the same side of the conductive plate 100 and are used to connect with a conductive component. In an embodiment, the upper conductive elastic arm 210 extends upward relative to the conductive plate 100, and the lower conductive plate 100 extends downward relative to the conductive plate 100. The upper conductive elastic arm 210 and the lower conductive elastic arm 220 have the same structure. Under the action of an external force, the end of the upper conductive elastic arm 210 away from the conductive plate 100 and the end of the lower conductive elastic arm 220 away from the conductive plate 100 can be close to each other to facilitate reliable connection with the conductive component; the end of the upper conductive elastic arm 210 away from the conductive plate 100 and the end of the lower conductive elastic arm 220 away from the conductive plate 100 can also be away from each other to disconnect the connection with the conductive component. The conductive component can be a wire, a circuit board, or an electrical connection device, etc., which is not limited here.

[0037] The upper conductive elastic arm 210 and the lower conductive elastic arm 220 are integrally formed with the conductive plate 100. In an embodiment, the upper conductive elastic arm 210 and the lower conductive elastic arm 220 are integrally formed with the conductive plate 100 by stamping, and of course, in other embodiments, the upper conductive elastic arm 210 and the lower conductive elastic arm 220 can also be integrally formed with the conductive plate 100 by processes such as insert molding, compound die forming or flanging forming, and here, the process of integral forming is not limited. In an embodiment, the materials of the upper conductive elastic arm 210, the lower conductive elastic arm 220 and the conductive plate 100 are all composite materials mixed with copper and steel, such as copper-stainless steel-copper composite materials or copper-based metal composite materials or copper-steel ceramic composite materials, so as to balance the strength, elasticity and conductivity of the terminal structure. Of course, in other embodiments, the material of the terminal structure can also be a multi-element composite material such as aluminum, steel or copper, and here, the specific material of the terminal structure is not limited. In this way, by integrally forming the terminal structure, on the one hand, the overall structure is simplified, and the assembly difficulty is reduced; on the other hand, the material is saved, and the production cost is reduced. By using a multi-element composite material, the strength, elasticity and conductivity of the terminal structure are balanced, and at the same time, it is ensured that the terminal structure can be repeatedly plugged and unplugged more than 10,000 times, so as to improve the service life of the terminal structure while improving the connection reliability of the terminal structure.

[0038] The technical scheme of the utility model discloses a terminal structure which comprises a conductive plate 100, an upper conductive elastic arm 210 and a lower conductive elastic arm 220. One end of the upper conductive elastic arm 210 is connected with the conductive plate 100, and one end of the lower conductive elastic arm 220 is connected with the conductive plate 100. The upper conductive elastic arm 210 and the lower conductive elastic arm 220 are integrally formed with the conductive plate 100, and the end of the upper conductive elastic arm 210 away from the conductive plate 100 and the end of the lower conductive elastic arm 220 away from the conductive plate 100 can be close to or away from each other. Compared with the terminal structure with a complex structure in the prior art, all the components in the terminal structure are integrally formed in the technical scheme of the utility model, the connection interface is reduced, and the connection stability is improved; the structure is simplified, the terminal structure is convenient to disassemble and assemble, and the universality of the terminal structure is improved.

[0039] Please refer to Figure 1 Further, in an embodiment, the upper conductive elastic arm 210 and the lower conductive elastic arm 220 are all provided with a plurality of upper conductive elastic arms 210 and lower conductive elastic arms 220, and the upper conductive elastic arms 210 and the lower conductive elastic arms 220 are alternately arranged.

[0040] In an embodiment, the number of the upper conductive elastic arms 210 and the lower conductive elastic arms 220 is consistent, and all the upper conductive elastic arms 210 and all the lower conductive elastic arms 220 are alternately arranged on the same side of the conductive plate 100. The specific number of the upper conductive elastic arms 210 and the lower conductive elastic arms 220 can be flexibly set according to actual needs, and here, no specific limitation is made.

[0041] In this way, by increasing the number of the upper conductive elastic arms 210 and the lower conductive elastic arms 220, the current carrying capacity of the terminal structure can be improved. The upper conductive elastic arms 210 and the lower conductive elastic arms 220 are arranged alternately, on one hand, the contact points with the conductive components can be dispersed to avoid heat accumulation, so that the current carrying capacity of the terminal structure is improved while the heat dissipation capacity is improved; on the other hand, the terminal structure is further simplified, the use space is saved, and the use flexibility is improved.

[0042] Please refer to Figure 1 In an embodiment, the terminal structure further comprises abutting structures 120, and the conductive plate 100 is provided with at least one abutting structure 120.

[0043] In an embodiment, the abutting structure 120 is provided with four. Among them, two abutting structures 120 are arranged on one side of the connecting hole 110, and the other two abutting structures 120 are arranged on the other side of the connecting hole 110. When the conductive plate 100 is connected with the electronic equipment, the abutting structure 120 is in contact with the electronic equipment and closely abuts, so as to concentrate the current and disperse the current, so as to realize stable large current contact. Further, in an embodiment, the abutting structures 120 on both sides of the connecting hole 110 are symmetrically distributed, so that the stress of the conductive plate 100 is more uniform. Specifically, in an embodiment, the abutting structure 120 is a convex bump integrally formed with the conductive plate 100, and here the process of integral forming is not limited. The convex bump is the main contact point of the conductive plate 100, on one hand, the convex convex bump can make the contact between the conductive plate 100 and the electronic equipment more closely and stably, so as to realize reliable connection; in addition, the contact surface area of the convex bump shape is larger, which can effectively reduce the contact resistance, guide the reasonable distribution of current, and improve the current carrying capacity. Among them, the shape of the convex bump can be spherical, cylindrical or polyhedral, etc., which is not limited here. Of course, in other embodiments, the abutting structure 120 can also be provided as an elastic member or a bending, etc., which is not limited here. Of course, in other embodiments, the abutting structure 120 can be provided with two or more, so as to ensure the reliability of the connection between the conductive plate 100 and the electronic equipment. Here, the specific number of the abutting structure 120 is not limited.

[0044] The technical scheme of the embodiment of the utility model discloses that the abutting structure 120 is arranged on the conductive plate 100, so that the connection between the conductive plate 100 and the electronic equipment is more stable, and the connection stability is improved. The abutting structure 120 can concentrate and disperse the current, so as to guide the reasonable distribution of current, improve the current carrying capacity of the terminal structure, avoid heat accumulation, and improve the use safety of the terminal structure.

[0045] Please refer to Figure 1 and Figure 2Further, in an embodiment, the upper conductive elastic arm 210 has a bending portion 240 at the end away from the conductive plate 100, and / or the lower conductive elastic arm 220 has a bending portion 240 at the end away from the conductive plate 100.

[0046] In an embodiment, the upper conductive elastic arm 210 and the lower conductive elastic arm 220 are both provided with the bending portion 240, and the bending portion 240 of the upper conductive elastic arm 210 is opposite to the bending portion 240 of the lower conductive elastic arm 220 in orientation. The upper conductive elastic arm 210 and the lower conductive elastic arm 220 are elastic by themselves, so that the bending portion 240 can be bent during the mating process and can restore to the original shape after connection. When the upper conductive elastic arm 210 and the lower conductive elastic arm 220 are mated with the conductive component, the bending portion 240 can be naturally bent to an angle required for connection to adapt the terminal structure to the mating structure of the conductive component. The bending portion 240 can be formed by bending, stretching or stamping and other processing techniques, which is not limited herein. Of course, in other embodiments, the bending portion 240 can also be provided only on the upper conductive elastic arm 210 or the lower conductive elastic arm 220, which is not specifically limited herein.

[0047] In this way, by providing the bending portion 240 on the upper conductive elastic arm 210 and the lower conductive elastic arm 220, on the one hand, the bending portion 240 can be adjusted to a suitable angle during use, improving the inclusiveness and connection accuracy of the terminal structure; on the other hand, the bending portion 240 has good elastic deformation ability, can maintain stable connection during use, and further improves the connection reliability of the terminal structure.

[0048] Please refer to Figure 1 and Figure 2In an embodiment, the upper conductive elastic arm 210 and the lower conductive elastic arm 220 are respectively provided with a slope 250, and the two slopes 250 are close to each other at one end away from the conductive plate 100 and are away from each other at the other end. The slope 250 can play a guiding role to guide the distribution of external force and current during plugging, reduce the contact impedance, and further improve the reliability and conductivity of the connection. Further, in an embodiment, the upper conductive elastic arm 210 and the lower conductive elastic arm 220 are respectively provided with a plane 260, and the included angle between the two planes 260 is greater than or equal to 0 degrees and less than or equal to 30 degrees. Specifically, in an embodiment, the included angle between the two planes 260 is equal to 0 degrees, that is, the two planes 260 are arranged in parallel. The end of the two planes 260 away from the conductive plate 100 is connected to the end of the two slopes 250 away from each other. The plane 260 can provide a stable connection surface to make the upper conductive elastic arm 210 and the lower conductive elastic arm 220 contact the conductive component more closely and improve the connection reliability. Of course, in other embodiments, the included angle between the two planes 260 can also be 10 degrees or 20 degrees, etc., but the included angle between the two planes 260 should be smaller than the included angle between the two slopes 250 to ensure that the plane 260 and the slope 250 can normally play a role. The size of the included angle between the two planes 260 and the size of the included angle between the two slopes 250 can be flexibly set according to actual needs, which is not limited here. In an embodiment, the upper conductive elastic arm 210 and the lower conductive elastic arm 220 are respectively provided with an arc surface 230, one end of the two arc surfaces 230 is connected to the conductive plate 100, and the other end of the two arc surfaces 230 is away from each other. The end of the two arc surfaces 230 away from each other is connected to the two planes 260. The arc surface 230 can absorb and relieve the connection stress to ensure the stable connection of the upper conductive elastic arm 210 and the lower conductive elastic arm 220 with the conductive plate 100 and reduce the wear in the use process.

[0049] In an embodiment, the slope 250, the plane 260 and the arc surface 230 on the upper conductive elastic arm 210 and the lower conductive elastic arm 220 combine to form a bending structure to facilitate the connection of the terminal structure and the conductive component. Of course, in other embodiments, the upper conductive elastic arm 210 and the lower conductive elastic arm 220 can also have only the slope 250 and the plane 260, the arc surface 230 and the plane 260, the slope 250 and the arc surface 230, or other forms of bending structure, which is not limited here.

[0050] The technical scheme of the embodiment of the utility model discloses that the slope 250, the plane 260 and the arc surface 230 are sequentially arranged on the upper conductive elastic arm 210 and the lower conductive elastic arm 220 to form a bending structure, which improves the elastic deformation capacity of the upper conductive elastic arm 210 and the lower conductive elastic arm 220. On the one hand, the use convenience and the use range of the terminal structure are improved. On the other hand, the service life of the terminal structure is improved, and the use reliability of the terminal structure is improved.

[0051] Referring to Figure 1 In an embodiment, the width of the upper conductive spring arm 210 at the end away from the conductive plate 100 is smaller than the width of the upper conductive spring arm 210 at the end close to the conductive plate 100; and the width of the lower conductive spring arm 220 at the end away from the conductive plate 100 is smaller than the width of the lower conductive spring arm 220 at the end close to the conductive plate 100.

[0052] Specifically, in an embodiment, the width of the inclined surface 250 is smaller than the width of the arc surface 230, and the width of the flat surface 260 at the end away from the conductive plate 100 is smaller than the width of the flat surface 260 at the end close to the conductive plate 100, which can increase the deflection of the upper conductive spring arm 210 and the lower conductive spring arm 220, and reduce the frictional force generated by the upper conductive spring arm 210 and the lower conductive spring arm 220 during the connection or disconnection with the conductive component, so as to facilitate the insertion and extraction of the terminal structure. In another embodiment, the width of the upper conductive spring arm 210 at the end close to the conductive plate 100 and the width of the lower conductive spring arm 220 at the end close to the conductive plate 100 are the largest, and the width of the upper conductive spring arm 210 and the width of the lower conductive spring arm 220 gradually decrease along the length direction thereof, so as to achieve progressive pressure distribution, which can also reduce the frictional resistance during the insertion and extraction. Herein, the width of the upper conductive spring arm 210 and the width of the lower conductive spring arm 220 are not specifically limited, and in an embodiment, the cross-sectional shape of the upper conductive spring arm 210 and the lower conductive spring arm 220 along the width direction thereof is rectangular, so as to facilitate the easy insertion and extraction with the conductive component and ensure good contact. Of course, in other embodiments, the cross-sectional shape of the upper conductive spring arm 210 and the lower conductive spring arm 220 can also be circular, wedge-shaped or other irregular shapes, which are not specifically limited herein.

[0053] Therefore, the width of the upper conductive spring arm 210 at the end away from the conductive plate 100 and the width of the lower conductive spring arm 220 at the end away from the conductive plate 100 are small, which improves the smoothness of the insertion and extraction of the terminal structure, avoids the damage of the terminal structure caused by excessive insertion and extraction force, and improves the service life of the terminal structure; the width of the upper conductive spring arm 210 at the end close to the conductive plate 100 and the width of the lower conductive spring arm 220 at the end close to the conductive plate 100 are large, which can provide a larger support area, prevent the upper conductive spring arm 210 and the lower conductive spring arm 220 from loosening or breaking during use, and improve the use safety of the terminal structure.

Since the present connector has adopted all technical solutions of above all embodiments, it at least has all beneficial effects brought by the technical solutions of above embodiments, which will not be repeated here.
