[0061] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, features defined as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0063] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0064] As the power of electric vehicles increases, high-current transmission has become a major way to improve power, and the application scenarios of high-current terminal connectors are becoming more and more widespread. In order to ensure their electrical performance, mechanical performance and safety, especially in applications requiring 90-degree transitions, existing high-voltage connector terminals or high-current connector terminals generally adopt complex terminal structure solutions or transition solutions. In addition to using multiple parts, the manufacturing process also involves multiple processes such as stamping, turning and riveting, resulting in complex structures and high costs.

[0065] To address the aforementioned problems, this application provides an adapter terminal 100, a connector, a terminal module, an electronic device, and a vehicle. The adapter terminal 100 includes a first insertion channel 110 and a second insertion channel 120, which are adapted to be formed by folding an integrally formed plate 130. The adapter terminal 100 of this invention forms the first insertion channel 110 and the second insertion channel 120 by folding an integrally formed plate 130, allowing for mating with two male terminals respectively. It achieves the adapter function using only a stamping process, eliminating the need for turning and riveting. This results in a simple structure, improved production efficiency, reduced costs, and high stability.

[0066] like Figure 1-4 As shown, the application embodiment provides an adapter terminal 100, which includes a first insertion channel 110 and a second insertion channel 120. The first insertion channel 110 and the second insertion channel 120 are at least partially overlapped in a first direction. The first insertion channel 110 and the second insertion channel 120 are adapted to be formed by folding an integrally formed plate 130.

[0067] The adapter terminal 100 of this application is formed by folding a one-piece molded plate 130, thus it is a single piece, providing high connection stability, reducing the failure rate, and ensuring the electrical, mechanical, and safety performance of the product. It eliminates the need to process multiple parts and complex processes, simplifying the production process, reducing processing time, and lowering production costs.

[0068] The first direction is vertical. The first connector channel 110 and the second connector channel 120 are at least partially overlapped in the first direction. The overlapping part can realize the electrical connection between the two male terminals of the first connector channel 110 and the second connector channel 120, and can also reduce the space occupied, realizing the adapter function with a smaller volume. In addition, it can also reduce the production materials and reduce the production cost.

[0069] It is understood that the shape of the plate 130 is not limited and can be flipped into two insertion channels. The specific insertion direction of the two insertion channels can be adjusted according to the shape of the plate 130. This embodiment does not impose too many restrictions.

[0070] Therefore, the adapter terminal 100 of this utility model embodiment is formed by folding an integrally molded plate 130 to form two insertion channels, thereby realizing the adapter function. It has high connection stability, simple shape and process, high processing efficiency and low cost. The insertion direction of the insertion channel can also be adjusted according to the needs, making the design flexible and allowing for quick adjustment of product functions and appearance.

[0071] In some embodiments, the insertion direction of the first connector channel 110 is the second direction, the insertion direction of the second connector channel 120 is the third direction, and the angle between the second direction and the third direction is 45°-135°.

[0072] The angle between the second direction and the third direction is 45°-135°, so the adapter terminal can achieve 45°-135° conversion. The angle of the first insertion channel 110 and the second folding channel 120 after the board body 130 is folded can be designed according to specific needs, which can adapt to various complex connection directions and improve the flexibility of conversion.

[0073] In some embodiments, the second direction is perpendicular to the first direction, and the third direction is perpendicular to the first direction.

[0074] The insertion direction of the first connector channel 110 is a second direction perpendicular to the first direction, and the insertion direction of the second connector channel 120 is a third direction perpendicular to the first direction. Therefore, the first connector channel 110 and the second connector channel 120 are located on two mutually parallel planes, which further saves the space occupied by the entire adapter terminal 100, and the whole structure is more aesthetically pleasing.

[0075] In some embodiments, the second direction and the third direction are perpendicular to each other.

[0076] The second direction and the third direction are perpendicular to each other. Therefore, the insertion directions of the first insertion channel 110 and the second insertion channel 120 are perpendicular to each other. Thus, this adapter terminal 100 can achieve a 90-degree conversion, with a compact structure that can significantly save internal or external space.

[0077] In some embodiments, the plate 130 has a first folding surface 131, a second folding surface 132 and a middle surface 133. The first folding surface 131 is folded to form a first insertion channel 110, and the second folding surface 132 is folded to form a second insertion channel 120.

[0078] like Figure 4 As shown, the plate 130 has a first folding surface 131, a second folding surface 132, and a middle surface 133. The first folding surface 131 is folded to form a first insertion channel 110, and the second folding surface 132 is folded to form a second insertion channel 120. By folding the first folding surface 131 and the second folding surface 132, two insertion channels can be formed. The whole structure is simple and the processing efficiency is high. The first insertion channel 110 and the second insertion channel 120 are connected by the middle surface 133, which further reduces the use of production materials and lowers production costs.

[0079] In some embodiments, the first folding surface 131 extends in a direction perpendicular to the second direction, the second folding surface 132 extends in a direction perpendicular to the third direction, the first folding surface 131 is inserted in the second direction after folding, and the second folding surface 132 is inserted in the third direction after folding.

[0080] In some embodiments, the first folding surface 131 and the second folding surface 132 are folded in opposite directions, and the ends of the first folding surface 131 and the second folding surface 132 are connected to the middle surface 133.

[0081] The first folding surface 131 folds upward along the adapter terminal 100 to form the first insertion channel 110, and the second folding surface 132 folds downward along the adapter terminal 100 to form the second insertion channel 120. The first insertion channel 110 and the second insertion channel 120 form a two-layer structure on the adapter terminal 100. After the first folding surface 131 folds upward, its end connects to the middle surface 133, and after the second folding surface 132 folds downward, its end connects to the middle surface 133. Therefore, the entire structure is neat and compact, and has a simpler and more aesthetically pleasing appearance.

[0082] In some embodiments, a solder joint is provided at the connection between the end of the first folded surface 131 and the second folded surface 132 and the middle surface 133.

[0083] The ends of the first folded surface 131 and the second folded surface 132 and the middle surface 133 can be connected by a solder joint 150. By welding the connection after folding, the overall strength and integrity of the terminal are further improved, the electrical performance and safety performance are enhanced, and the occurrence of faults is reduced.

[0084] It is understood that the ends and middle surfaces 133 of the first folded surface 131 and the second folded surface 132 can be welded in-mold, and there can be multiple weld points, as long as the connection is stable. This embodiment does not impose too many restrictions.

[0085] In some embodiments, the first folding surface 131 and the second folding surface 132 are provided with a bending portion 140.

[0086] The first folding surface 131 and the second folding surface 132 are provided with a bending portion 140 that extends into the insertion channel. The bending portion 140 can be connected to the male end inserted into the insertion channel, and apply a force to it to cooperate with the male end and the insertion channel, thereby increasing the firmness of the connection between the male end and the insertion channel and ensuring the stability of the electrical connection.

[0087] It is understood that the bent portion 140 of the first folding surface 131 can be located on the top wall of the first insertion channel 110, and the bent portion 140 of the second folding surface 132 can be located on the bottom wall of the first insertion channel 110, as long as the male end can be fixed in the insertion channel. This embodiment does not impose too many restrictions on the specific position of the bent portion 140.

[0088] In some embodiments, the bend 140 is elastic.

[0089] The bends 140 on the first folding surface 131 and the second folding surface 132 are elastic, thus facilitating the insertion and removal of the male end, and when the male end is inserted into the connecting channel, the bends 140 exert a force into the connecting channel.

[0090] In some embodiments, the bent portion 140 is provided with a plurality of first contact portions 160.

[0091] The bending portion 140 is provided with a plurality of first contact portions 160, which are arranged at intervals on the bending portion 140. The plurality of first contact portions 160 can ensure the stability of the male terminal connection. Even if one of the contact portions or springs fails due to external force or abnormal contamination, the remaining contact portions can still ensure the stability of the connection. At the same time, the current density of a single bending portion 140 can be reduced.

[0092] In some embodiments, the first contact portion 160 is arranged in an array.

[0093] In some embodiments, the bending portion includes a plurality of first bending portions 141, second bending portions 142, third bending portions 143 and fourth bending portions 144. The first bending portions 141 and second bending portions 142 are spaced apart on the first flip surface 131 and extend in opposite directions. The third bending portions 143 and fourth bending portions 144 are spaced apart on the second flip surface 132 and extend in opposite directions.

[0094] The first folding surface 131 is provided with a first bend 141 and a second bend 142 spaced apart, and the second folding surface 132 is provided with a third bend 143 and a fourth bend 144 spaced apart. The first bend 141 and the second bend 142 extend in opposite directions, and the third bend 143 and the fourth bend 144 extend in opposite directions. Therefore, the stability of the connection when the male terminal is plugged in is further enhanced, and the connection failure caused by external force is avoided.

[0095] In some embodiments, the first folded surface 131 is inserted in the second direction after folding, the second folded surface 132 is inserted in the third direction after folding, the first bent portion 141 extends along the second direction, the second bent portion 142 extends in the opposite direction to the second direction, the third bent portion 143 extends in the third direction, and the fourth bent portion 144 extends in the opposite direction to the third direction.

[0096] In some embodiments, the middle surface 133 is provided with a plurality of second contact portions 170 on both sides near the first insertion channel 110 and near the second insertion channel 120.

[0097] Multiple second contact portions 170 are provided on both sides of the middle surface 133 near the first insertion channel 110 and near the second insertion channel 120. Therefore, when the male end is inserted, under the action of the bending portion 140, the second contact portions 170 on both sides of the middle surface 133 contact the upper and lower surfaces of the two male ends respectively, forming an electrical connection. The multiple second contact portions 170 can ensure the stability of the connection. Even if one of the contact portions fails due to external force or abnormal contamination, the remaining contact portions can still ensure the stability of the connection. In addition, the two male ends are connected through the contact portions of the middle surface 133, which increases the stability of the connection and reduces the loss in the power transmission process.

[0098] It is understood that the second contact portion 170 can be arranged in an array or other arrangements. The shape of the second contact portion 170 is preferably a square structure, but it can also be a semi-circular structure, as long as it can ensure that the male end is stably connected and fully contacts the contact portion. This embodiment does not impose too many restrictions.

[0099] In some embodiments, the second contact portions 170 are arranged in an array and have a square shape. The heights of the multiple second contact portions 170 are basically the same, so the contact between the multiple second contact portions 170 and the male end is more stable.

[0100] like Figure 5 As shown, part of the current flow path is as follows: the male terminal located in the first connector channel 110 is conducted to the intermediate surface 133 through the second contact portion 170, and then conducted to the male terminal located in the second connector channel 120 through the intermediate surface 133, thereby completing the current transmission; another part of the current flow path is as follows: the male terminal located in the first connector channel 110 is conducted to the first folded surface 131 through the first contact portion 160 on the first bend portion 141 and the second bend portion 142, then conducted from the first folded surface 131 to the second folded surface 132, and then conducted from the first contact portion 160 on the third bend portion 143 and the fourth bend portion 144 to the male terminal of the second connector channel 120, thereby completing the current transmission.

[0101] This utility model embodiment also discloses a connector, which includes the aforementioned adapter terminal 100 and sheath 200. This connector possesses all the beneficial effects of the aforementioned adapter terminal 100, which will not be repeated here.

[0102] Specifically, the sheath 200 protects the adapter terminal 100, which may be subjected to various physical impacts or compressions. It prevents the adapter terminal 100 from being worn or broken by external forces, thus ensuring the stability and durability of the electrical connection. It also provides insulation protection for the adapter terminal 100, preventing electrical faults. Furthermore, the sheath 200 prevents moisture and dust from entering the adapter terminal 100, thereby keeping the electrical connection clean and dry and extending the service life of the electrical system.

[0103] In some embodiments, the adapter terminal 100 is provided with a plurality of protrusions 180.

[0104] The connection between the adapter terminal 100 and the sheath 200 is provided with multiple protrusions 180. Therefore, when the adapter terminal 100 is installed inside the sheath 200, the displacement of the adapter terminal 100 can be restricted, thereby increasing the stability of the connection between the adapter terminal 100 and the sheath 200.

[0105] In some embodiments, the protrusion 180 is a circular or square protrusion structure that protrudes upward perpendicular to the terminal surface.

[0106] In some embodiments, the adapter terminal 100 is provided with a snap-fit ​​portion 190.

[0107] The adapter terminal 100 and the sheath 200 are connected by a snap-fit ​​part 190. The adapter terminal 100 and the sheath 200 are connected by the snap-fit ​​part 190 to prevent the adapter terminal 100 from coming off the sheath 200 and to keep the adapter terminal 100 stably inside the sheath 200.

[0108] In some embodiments, the snap-fit ​​portion 190 is disposed on the second folded surface 132, located on the left and right sides of the second insertion channel 120, and the snap-fit ​​portion 190 is a cantilever structure extending in the opposite direction to the insertion direction of the male end. For example... Figure 6 As shown, the sheath has a groove 210 that mates with the snap-fit ​​part 190, and the snap-fit ​​part 190 can be located within the groove 210.

[0109] In some embodiments, the sheath 200 is provided with a connecting portion 220, through which a plurality of connectors can be connected.

[0110] like Figure 7As shown, the sheath 200 is provided with a connecting portion 220, through which multiple connectors can be connected. Therefore, multiple connectors can be detachably connected via the connecting portion 220. Multiple connectors can be interconnected to form an array module. The connecting portion 220 enables a modular structure among the multiple connectors, resulting in a simpler structure and easier maintenance.

[0111] In some embodiments, the connecting portion 220 includes a convex portion 221 and a recessed portion 222 that cooperate with each other.

[0112] In some embodiments, the sheath 200 has an approximately square structure, the protrusion 221 is an approximately dovetail structure protruding outward on the sheath 200, and the recess 222 is an approximately dovetail groove structure recessed inward from the surface of the body. The protrusion 221 and the recess 222 can be connected by a slight interference fit.

[0113] This utility model embodiment also discloses a terminal module, which includes the above-mentioned adapter terminal 100 or the above-mentioned connector. The terminal module has all the beneficial effects of the above-mentioned adapter terminal 100, which will not be repeated here.

[0114] In some embodiments, the sheath 200 and the adapter terminal 100 cooperate to form a standard component module. The terminal module also includes a terminal sheath 300. The standard component module can cooperate with the terminal sheath 300 to form a terminal module to meet the final connector requirements.

[0115] In some embodiments, multiple connectors form an array module through protrusions 221 and recesses 222. The array module can be placed into the terminal sheath 300 through similar mating protrusions and mating dies to form a terminal module.

[0116] This utility model embodiment also discloses an electronic device, which includes the above-described adapter terminal 100, or the above-described connector, or the above-described terminal module. The electronic device has all the beneficial effects of the above-described adapter terminal 100, which will not be repeated here.
