Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage connector components, in particular to a high-stability high-voltage connector component. Background Art

[0002] New energy vehicle high-voltage connectors are electrical connection components specifically designed for use in the medium- and high-voltage circuit systems of new energy vehicles. These connectors are responsible for establishing reliable electrical connections between high-voltage components such as battery packs, electric motors, controllers, and chargers, ensuring efficient and safe power transmission.

[0003] One of the primary functions of a high-voltage connector housing is to provide electrical insulation, protecting internal electrical components and circuitry from the external environment. An unstable connection between the interface and the socket can cause the connection to separate or break, exposing the internal circuitry to direct contact with the external environment. This increases the risk of leakage and short circuits, potentially leading to fire or electric shock. Therefore, a high-voltage connector assembly with a more stable connection is urgently needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a high-stability high-voltage connector assembly.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high-stability high-voltage connector assembly comprises a high-voltage connector interface assembly and a high-voltage connector socket assembly, wherein the upper and lower sides of the high-voltage connector socket assembly are fixedly provided with a holder, and a limit cavity is provided on the holder; the upper and lower sides of the high-voltage connector interface assembly are fixedly provided with a fixing plate, and the fixing plate is movably provided with a limit piece, and the limit piece is adapted to the limit cavity.

[0007] In addition, a preferred structure is that card posts are fixedly and vertically provided on both sides of the card holder facing the high-voltage connector interface assembly, and card cavities are adapted to be opened on the high-voltage connector interface assembly corresponding to the card posts.

[0008] In addition, a preferred structure is that fixing plates are fixedly provided on both the upper and lower sides of the high-voltage connector interface assembly, and a plurality of springs are installed on the fixing plates.

[0009] In addition, a preferred structure is that the other end of the spring on each of the fixing plates is connected to the limiting member, and the limiting member is adapted to be clamped in the limiting cavity.

[0010] In addition, a preferred structure is that the limiting member is arranged in a "wedge shape", and the slopes of the limiting member are all directed toward the high-voltage connector socket assembly.

[0011] In addition, a preferred structure is that when the limiting member contacts the holder, the spring contracts and the limiting member moves outward; when the limiting member is located outside the limiting cavity, the spring and the limiting member are reset by elastic force.

[0012] The beneficial effect of the present invention is that through the adaptation setting of the card column and the card cavity and the mutual locking between the limit piece and the limit cavity, the stability of the high-voltage connector interface assembly and the high-voltage connector socket assembly during connection can be improved, thereby improving the safety of the device during connection.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-4 A high-stability high-voltage connector assembly includes a high-voltage connector interface assembly 1 and a high-voltage connector socket assembly 2. A holder 3 is fixedly provided on both the upper and lower sides of the high-voltage connector socket assembly 2, and a limit cavity 32 is defined on each holder 3. A fixing plate 4 is fixedly provided on both the upper and lower sides of the high-voltage connector interface assembly 1, and a limit member 42 is movably provided on each fixing plate 4, and each limit member 42 is adapted to fit within the limit cavity 32.

[0020] The specific circuit structures of the high-voltage connector interface assembly 1 and the high-voltage connector socket assembly 2 are both prior arts, and therefore are not described in detail in the present invention.

[0021] The holder 3 has fixed vertical posts 31 on both sides of the side facing the high-voltage connector interface assembly 1, and the high-voltage connector interface assembly 1 has corresponding posts 31 adapted to form a card cavity 5. The adaption between the posts 31 and the card cavity 5 can guide the high-voltage connector interface assembly 1 and the high-voltage connector socket assembly 2 when they are connected, thereby improving the connection effect.

[0022] A fixing plate 4 is fixedly mounted on both the upper and lower sides of the high-voltage connector interface assembly 1, and multiple springs 41 are mounted on each fixing plate 4. The other end of each spring 41 on the fixing plate 4 is connected to a stopper 42, which is then adapted to be locked within the stopper cavity 32. The springs 41 provide a push on the stopper 42, pushing it into the stopper cavity 32 and locking it there, thereby improving the stability of the high-voltage connector interface assembly 1 and the high-voltage connector socket assembly 2 when connected together.

[0023] The stopper 42 is wedge-shaped, with its slopes facing the high-voltage connector socket assembly 2. When the stopper 42 contacts the retaining socket 3, the spring 41 contracts and the stopper 42 moves outward. When the stopper 42 is outside the retaining cavity 32, the spring 41 and the stopper 42 return to their original position through elastic force.

[0024] In this embodiment, when the user needs to connect the high-voltage connector interface assembly 1 and the high-voltage connector socket assembly 2 together, he only needs to insert the high-voltage connector socket assembly 2 into the high-voltage connector interface assembly 1. At this time, the card column 31 on the card holder 3 can be adapted to be inserted into the card cavity 5 in the high-voltage connector interface assembly 1, thereby improving the stability of the connection between the high-voltage connector interface assembly 1 and the high-voltage connector socket assembly 2.

[0025] Furthermore, when the user connects the high-voltage connector interface assembly 1 and the high-voltage connector socket assembly 2, the stopper 42 on the fixing plate 4 first contacts the holder 3. Since the stopper 42 is wedge-shaped, when the slope on the stopper 42 contacts the holder 3, the stopper 42 automatically moves upward and the spring 41 is compressed.

[0026] When the stopper 42 moves to the outside of the limit cavity 32, the spring 41 automatically resets due to its elastic force, thereby driving the stopper 42 to automatically move back to the limit cavity 32. When the stopper 42 moves into the limit cavity 32, the mutual engagement between the stopper 42 and the high-voltage connector interface assembly 1 and the high-voltage connector socket assembly 2 can improve the connection stability.

[0027] In the present invention, by the adaptation setting of the clamping column 31 and the clamping cavity 5 and the mutual clamping between the limiting member 42 and the limiting cavity 32, the stability of the high-voltage connector interface assembly 1 and the high-voltage connector socket assembly 2 during connection can be improved, thereby improving the safety of the device during connection.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
