Description

Technical Field

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

[0002] In power transmission and distribution systems, high-voltage connectors are key components responsible for connecting and disconnecting high-voltage circuits. Their performance directly impacts the safety and reliability of the system. With the development of the power industry, the requirements for high-voltage connectors are becoming increasingly stringent. This is particularly true in areas such as electric vehicles, industrial automation equipment, and large-scale power facilities. High-voltage connectors must not only possess high conductivity and low resistivity, but also excellent sealing, high-voltage resistance, ease of operation, and a high-security locking mechanism.

[0003] Traditional high-voltage connectors achieve electrical connection between the plug and socket by plugging and unplugging them. To ensure reliable connection and prevent them from becoming disengaged due to factors such as vibration during use, the plug and socket are typically designed to lock together using a snap-on design. However, high-voltage connectors installed on high-voltage equipment are subject to various vibrations and shocks during actual use. The long-term accumulation of vibrations and shocks can gradually weaken the locking force between the plug and socket, causing the connection to become loose. This can easily lead to the two becoming disengaged, affecting the normal operation of the high-voltage connector and causing power transmission interruptions or instability.

[0004] The above defects need to be solved urgently. Utility Model Content

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] like Figure 1 、 Figure 2As shown, the present invention provides a high-voltage connector, including a plug assembly 1, a socket assembly 2, and a locking member 3. The plug assembly 1 is plugged into the socket assembly 2, and at least a portion of the socket assembly 2 is embedded in the plug assembly 1. A first engaging portion 11 is provided on the plug assembly 1, and a second engaging portion 21 is correspondingly provided on the socket assembly 2. The first engaging portion 11 and the second engaging portion 21 are engaged with each other. Specifically, an engaging step 211 is provided on the first engaging portion 11, and the lower end of the second engaging portion 21 is engaged with the engaging step 211, thereby achieving a preliminary and stable connection between the plug assembly 1 and the socket assembly 2, effectively preventing the two from being separated due to external forces, and providing a solid foundation for subsequent power transmission.

[0042] like Figures 1 to 6 As shown, in this embodiment, the plug assembly 1 is provided with a slide groove 12, and the locking member 3 can slide along the slide groove 12 to switch the locking member 3 between a locked position and an unlocked position. The plug assembly 1 is provided with a first locking portion 13, and the locking member 3 is correspondingly provided with a second locking portion 31. The socket assembly 2 is provided with a third locking portion 22, and the locking member 3 is correspondingly provided with a fourth locking portion 32. The second locking portion 31 and the fourth locking portion 32 are arranged in sequence along the plug-in and pull-out direction of the plug assembly 1 and the socket assembly 2. When the locking member 3 is in the locked position, the first locking portion 13 engages with the second locking portion 31, and the third locking portion 22 engages with the fourth locking portion 32, thereby achieving "double locking". This enhances the connection stability between the plug assembly 1 and the socket assembly 2, ensures the continuity and stability of power transmission, and avoids power interruption or instability caused by loose connections.

[0043] like Figure 9 、 Figure 10 、 Figure 11 As shown, in this embodiment, the locking member 3 includes a base 33, a locking arm 34, two first limiting arms 35, and two guide arms 36. The locking arm 34 is formed by protruding outward from one side of the base 33. The two first limiting arms 35 are respectively arranged on both sides of the locking portion, and the two guide arms 36 are respectively arranged on one side of the first limiting arm 35 close to the locking arm 34.

[0044] like Figures 1 to 3As shown, in this embodiment, when the locking member 3 is in the locked position, one side of the base 33 abuts against the notch wall of the slide 12, thereby limiting the locking member 3 to the locked position in the slide 12. In addition, a first gripping groove 331 is provided on the base 33, and a second gripping groove 14 is correspondingly provided on the surface of the plug assembly 1. The first gripping groove 331 cooperates with the second gripping groove 14 to facilitate switching the locking member 3 to the unlocked position. When it is necessary to separate the plug assembly 1 and the socket assembly 2, the first gripping groove 331 is grasped and the locking member 3 is pulled outward, so that the first locking portion 13 and the second locking portion 31 are disengaged, and the third locking portion 22 and the fourth locking portion 32 are disengaged, thereby achieving the first unlocking of the plug assembly 1 and the socket assembly 2.

[0045] like Figure 1 、 Figure 4 As shown, in this embodiment, a first limiting groove 332 is provided at the bottom of the base 33, and a first limiting protrusion 15 is correspondingly provided on the plug assembly 1. When the locking member 3 is in the unlocked position, the first limiting protrusion 15 abuts against the side wall of the first limiting groove 332, which can limit the locking member 3. By limiting the movement range of the locking member 3 in the slide groove 12 of the plug assembly 1, the mutual cooperation between the first limiting protrusion 15 and the first limiting groove 332 effectively prevents the locking member 3 from falling out of the slide groove 12 in the unlocked state, thereby ensuring the overall structural stability and operational safety of the connector.

[0046] like Figure 3 、 Figure 4 、 Figures 7 to 11 As shown, in this embodiment, the second locking portion 31 and the fourth locking portion 32 are both disposed on a locking arm 34. A gap is provided between the locking arm 34 and the sidewall of the chute 12, providing room for deformation of the locking arm 34 and facilitating the switching of the locking member 3 between the locked and unlocked positions. Furthermore, a first inclined surface is provided on the first locking portion 13 of the plug assembly 1, and a second inclined surface is provided on the second locking portion 31 of the locking arm 34. When the locking member 3 is in the locked position, the first inclined surface contacts the second inclined surface. When the locking member 3 switches from the locked position to the unlocked position, the locking member 3 moves toward the first limiting protrusion 15, causing the second inclined surface of the second locking portion 31 to slide along the first inclined surface of the first locking portion 13. The guiding effect of the inclined surfaces gradually weakens the engagement between the first locking portion 13 and the second locking portion 31 until it is completely released, facilitating the initial unlocking of the plug assembly 1 and the receptacle assembly 2.

[0047] like Figure 3 、 Figure 4 、 Figures 7 to 11As shown, in this embodiment, the third locking portion 22 of the socket assembly 2 is disposed on a side of the second engaging portion 21 that is adjacent to the plug assembly 1. The third locking portion 22 and the second engaging portion 21 are sequentially arranged along the insertion and removal direction of the plug assembly 1 and the socket assembly 2. Furthermore, third inclined surfaces are provided on opposite sides of the third locking portion 22 of the socket assembly 2. The third locking portion 22 is in the shape of a quadrangular pyramid. The fourth locking portion 32 of the locking member 3 is an arcuate surface that cooperates with the third inclined surface to facilitate switching of the locking member 3 between the locked and unlocked positions. When the locking member 3 switches from the locked position to the unlocked position, the locking member 3 moves toward the first limiting protrusion 15. The arcuate surface of the fourth locking portion 32 moves along the third inclined surface of the third locking portion 22 that is adjacent to the second engaging portion 21. This gradually weakens the engagement between the third locking portion 22 and the fourth locking portion 32 until it is completely released, facilitating the initial unlocking of the plug assembly 1 and the socket assembly 2. In addition, when the locking member 3 switches from the unlocked position to the locked position, the arc surface of the fourth locking portion 32 moves along the third inclined surface of the third locking portion 22 away from the second locking portion 21, thereby realizing the clamping of the third locking portion 22 and the fourth locking portion 32, and further realizing a stable connection between the third locking portion 22 and the fourth locking portion 32.

[0048] like Figure 3 、 Figures 6 to 11 As shown, in this embodiment, a first limiting arm 35 is respectively provided on both sides of the locking portion, and a second limiting arm 23 is correspondingly provided on the socket assembly 2. When the locking member 3 is correctly pushed into the slide groove 12 and locked in the locking position, the end of the first limiting arm 35 abuts against the end of the second limiting arm 23, effectively limiting the movement of the locking member 3 in the horizontal direction, thereby avoiding accidental unlocking or loosening due to external force.

[0049] like Figure 3 、 Figures 6 to 11 As shown, in this embodiment, a second limiting groove 351 is provided on the side of the first limiting arm 35 away from the locking arm 34, and a second limiting protrusion 16 is correspondingly provided on the plug assembly 1. When the locking member 3 is in the locked position, at least a portion of the second limiting protrusion 16 is embedded in the second limiting groove 351, further limiting the locking member 3, thereby enhancing the connection strength between the plug assembly 1 and the socket assembly 2, and further improving the stability and reliability of the locking member 3 in the locked state.

[0050] like Figure 3 、 Figure 6 、 Figures 7 to 11As shown, in this embodiment, a guide arm 36 is provided on one side of the first limiting arm 35 near the locking arm 34, with a gap between the guide arm 36 and the locking arm 34, further providing room for deformation of the locking arm 34. When the locking member 3 is in the locked position, the guide arm 36 contacts the side arm of the second limiting arm 23. The guide arm 36 ensures that the locking member 3 is accurately positioned in the locked state, while also providing additional stability and reliability to the connection between the plug assembly 1 and the receptacle assembly 2.

[0051] like Figure 3 、 Figure 6 、 Figures 7 to 11 As shown, in this embodiment, the plug assembly 1 is provided with an unlocking pressing area 17, the second grip groove 14 is located within the unlocking pressing area 17, and the unlocking pressing area 17 is located above the locking arm 34. When the locking member 3 is in the unlocked position, pressing the unlocking pressing area 17 causes the first engaging portion 11 of the plug assembly 1 to spring up, so that the first engaging portion 11 of the plug assembly 1 and the second engaging portion 21 of the socket assembly 2 are no longer in contact, thereby achieving a second unlocking of the plug assembly 1 and the socket assembly 2, thereby separating the plug assembly 1 from the socket assembly 2.

[0052] When the plug assembly 1 and the socket assembly 2 are assembled, the locking member 3 is first moved to the side away from the first limiting protrusion 15 of the plug assembly 1 to the locking position, so that the second locking portion 31 of the locking member 3 is engaged with the first locking portion 13 of the plug assembly 1; then the socket assembly 2 is plugged into the plug assembly 1, so that the first engaging portion 11 of the plug assembly 1 is engaged with the second engaging portion 21 of the socket assembly 2, and at the same time, the fourth locking portion 32 of the locking member 3 is engaged with the third locking portion 22 of the socket assembly 2, thereby achieving a stable connection between the plug assembly 1 and the socket assembly 2.

[0053] When the plug assembly 1 is separated from the socket assembly 2, the locking member 3 is first moved toward the side close to the first limiting protrusion 15 of the plug assembly 1. The first limiting protrusion 15 abuts against the side wall of the first limiting groove 332 of the locking member 3, thereby positioning the locking member 3 in the unlocked position. At this time, the first locking portion 13 of the plug assembly 1 is no longer engaged with the second locking portion 31 of the locking member 3, and the third locking portion 22 of the socket assembly 2 is no longer engaged with the fourth locking portion 32 of the locking member 3, thereby achieving the first unlocking of the plug assembly 1 and the socket assembly 2. The unlocking pressing area 17 on the plug assembly 1 is then pressed, causing the first engaging portion 11 of the plug assembly 1 to spring up, thereby disengaging the first engaging portion 11 of the plug assembly 1 from the second engaging portion 21 of the socket assembly 2, thereby achieving the second unlocking of the plug assembly 1 and the socket assembly 2, thereby separating the plug assembly 1 from the socket assembly 2.

[0054] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.

[0055] The above is an exemplary description of the present utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the present utility model patent is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present utility model patent, or the concept and technical solution of the present utility model patent are directly applied to other occasions without improvement, they are all within the scope of protection of the present utility model.
