[0002] In the field of new energy vehicles, a high-voltage interlock detection mechanism is usually provided in the high-voltage connector, that is, a safety mechanism that uses low-voltage signals to monitor the integrity of the high-voltage circuit. High-voltage interlocking also refers to the dangerous voltage interlocking circuit: it uses low-voltage signals to detect the electrical integrity of the entire high-voltage product, wires, connectors and covers, and when abnormal circuit disconnection is identified, the high-voltage electricity is disconnected in time to ensure the safety of people and vehicles. At present, the high-voltage interlocking structures on high-voltage connectors on the market vary, such as pin-type structures, sheet-type structures, etc. The principle is that there is a U-shaped pin on the male end that conducts to the female end. After the pin on the female end is conducted, the signal is received by the vehicle controller, so that the vehicle determines that the connector has been plugged in and can be powered on.

[0003] In the related art, the male end of the high-voltage interlocking structure is usually integrated with the male end of the connector of the high-voltage wiring harness. When the vehicle is running, the high-voltage wiring harness will vibrate irregularly, driving the male end of the high-voltage interlocking structure fixed to it to vibrate together, which can easily cause the male end of the high-voltage interlocking structure to become detached or misplaced, and intermittently have poor contact with its female end, causing a false alarm of a high-voltage interlocking fault, resulting in the vehicle being unable to power on and drive normally, causing serious trouble to the driver.

[0038] Reference below Figure 1-Figure 4 An electrical connector 1, an energy storage device and an electrical device according to an embodiment of the utility model are described.

[0039] like Figure 1 and Figure 2 As shown, according to the electrical connector 1 of the first embodiment of the utility model, the electrical connector 1 includes: a first end 12 and a second end 11 .

[0040] Among them, a first limiting portion is provided on the first end 12; the second end 11 is plugged with the first end 12 along a first direction to achieve electrical connection, and a second limiting portion 111 is provided on the second end 11 to cooperate with the first limiting portion, and the first limiting portion and the second limiting portion 111 are limitedly cooperated in the second direction, and the first direction is different from the second direction and has an angle.

[0041] Specifically, the first end 12 and the second end 11 can be plugged together along the first direction to achieve electrical connection of the electrical connector 1. Exemplarily, the electrical connector 1 can be a high-voltage connector, and the first end 12 and the second end 11 are respectively the female end and the male end of the high-voltage connector, and the female end and the male end can be selectively plugged together to connect the high-voltage circuit of the high-voltage connector; when the first end 12 is plugged with the second end 11, the first limit portion and the second limit portion 111 can be limited in the second direction, and the second direction is different from the first direction and has an angle, so that the first limit portion and the second limit portion 111 can prevent the first end 12 and the second end 11 from moving relative to each other in the first direction, and can improve the plug-in stability of the first end 12 and the second end 11.

[0042] It should be pointed out that the electrical connector 1 disclosed in the embodiment of the utility model can be used in, but not limited to, electrical equipment or energy storage devices such as vehicles, ships or aircraft. The electrical connector 1 having the first end 12, the second end 11, etc. disclosed in the present application can be used to form the electrical equipment or energy storage device, which is conducive to improving the scope of application of the electrical connector 1 and improving the working reliability and efficiency of the electrical equipment and energy storage device.

[0043] According to the electrical connector 1 of the utility model, the first limiting portion and the second limiting portion 111 can cooperate to play a limiting role when the first end 12 and the second end 11 are plugged in, which can avoid the first end 12 and the second end 11 from being misaligned or disengaged, and can effectively improve the connection reliability and stability of the first end 12 and the second end 11, optimize the vibration resistance of the electrical connector 1 when the circuit is turned on, thereby preventing the interlocking detection mechanism from reporting a false alarm, and can improve the working reliability and efficiency of the energy storage device and electrical equipment.

[0044] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, there are multiple first limiting portions, which are spaced apart in the length direction of the first end 12 , and the second limiting portions 111 are arranged corresponding to the first limiting portions.

[0045] Specifically, the first limiting portion can be constructed as a plurality of portions that are spaced apart in the length direction of the first end 12, and the second limiting portion 111 can be constructed as a plurality of portions that correspond one to one to the first limiting portion. In this way, the plurality of first limiting portions and the plurality of second limiting portions 111 can be limited at multiple locations between the first end 12 and the second end 11, which can further enhance the stability of the first end 12 and the second end 11 when they are plugged in, and further ensure that the electrical connector 1 can be stably in a circuit-conducting state.

[0046] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the first limiting portion is configured as a plug hole, and the second limiting portion 111 is configured as an inserting protrusion to cooperate with the plug hole in a limiting manner.

[0047] Specifically, the first limiting portion can be configured as a socket, and the second limiting portion 111 can be configured as a plug-in convex portion, and at least a portion of the plug-in convex portion can extend into the socket and abut against at least a portion of the inner wall of the socket to achieve a limiting match with the socket. The plug-in convex portion is matched with the socket, so that when the first end 12 and the second end 11 are plugged and matched, the plug-in convex portion can be easily and quickly connected with the socket to form a limiting structure, thereby improving the convenience and efficiency of the limiting operation of the first limiting portion and the second limiting portion 111, and can timely play a good role in preventing the first end 12 and the second end 11 from falling off.

[0048] In addition, in some other specific embodiments of the present invention, the second limiting portion 111 is configured as a plug hole, and the first limiting portion is configured as an inserting protrusion, and is limitedly matched with the plug hole.

[0049] like Figure 3 and Figure 4As shown, according to some embodiments of the present invention, the second limiting portion 111 includes: a first plate 1111 and a second plate 1112, one end of the first plate 1111 is connected to the second end 11, the other end of the first plate 1111 is connected to one end of the second plate 1112, and a non-straight angle is provided between the second plate 1112 and the second end 11.

[0050] Specifically, one end of the first plate 1111 can be connected to the surface of the second end 11 facing the first end 12, and the other end of the first plate 1111 is connected to one end of the second plate 1112. The second plate 1112 extends away from the first plate 1111 and has a non-straight angle with the second end 11, that is, the extension direction of the second plate 1112 has a certain angle with the first direction. In this way, the second plate 1112 and the first plate 1111 can be pushed against each other in the first direction after being limitedly connected with the first limiting portion, which can limit the relative movement of the first end 12 and the second end 11 in the first direction, ensure that the first end 12 and the second end 11 are in good contact, and improve the working reliability of the electrical connector 1 in a bumpy environment.

[0051] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, an obtuse angle or a right angle is provided between the first plate 1111 and the second plate 1112, and a connection area between the first plate 1111 and the second plate 1112 is formed as a limiting area.

[0052] Specifically, the first plate 1111 and the second plate 1112 extend in different directions, and there is an obtuse angle or a right angle between the two. The connection area between the first plate 1111 and the second plate 1112 is formed as a limiting area, so that the limiting area can be concave or convex relative to the surface of the second end 11 in the second direction, and push against each other with the first limiting portion in the first direction. Therefore, by setting an obtuse angle or a right angle between the first plate 1111 and the second plate 1112, the limiting strength between the first plate 1111, the second plate 1112 and the first limiting portion can be enhanced, and the anti-detachment performance of the first end 12 and the second end 11 can be improved. In addition, by setting an obtuse angle or a right angle between the first plate 1111 and the second plate 1112, it can also be achieved that when the first limiting portion cooperates with the limiting area, the angle between the cooperation direction and the first direction is an acute angle, so that during the plug-in process of the first end 12 and the second end 11 along the first direction, the cooperation between the first limiting portion and the second limiting portion 111 can be guided, and the convenience of the limiting connection between the first limiting portion and the second limiting portion 111 can be improved.

[0053] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the other end of the second plate 1112 is connected to the third plate 1113, and the other end of the third plate 1113 is connected to the second end 11.

[0054] Specifically, the third plate 1113 is arranged at the other end of the second plate 1112 and connected to the second end 11, that is, the first plate 1111, the second plate 1112, and the third plate 1113 are sequentially connected in the first direction, and the first plate 1111 and the third plate 1113 are respectively connected to the surface of the second end 11 facing the first end 12 to form a first limiting portion. Among them, the connection area between the first plate 1111 and the second plate 1112 can be formed as a first limiting area, and the connection area between the third plate 1113 and the second plate 1112 can be formed as a second limiting area. The first limiting area and the second limiting area are suitable for limiting with the same first limiting part, so that when the first end 12 and the second end 11 are in a fully plugged state, the first limiting part and the second limiting part 111 can not only limit the first end 12 and the second end 11 from moving toward each other in the first direction, but also limit the first end 12 and the second end 11 from moving away from each other in the first direction, which can further optimize the vibration and anti-slip performance of the first end 12 and the second end 11.

[0055] like Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the first plate 1111 and the third plate 1113 are arranged in parallel.

[0056] Specifically, the extension direction of the first plate 1111 can be parallel to the extension direction of the second plate 1112, so that the third plate 1113 and the second end 11 have a non-straight angle and the same size as the non-straight angle between the second plate 1112 and the second end 11. In this way, the second limiting area between the third plate 1113 and the second plate 1112 and the first limiting area between the first plate 1111 and the second plate 1112, when cooperated with the first limiting portion, have the same limiting strength but opposite directions of action in the first direction, thereby improving the anti-slip balance between the first end 12 and the second end 11 in the first direction and enhancing the limiting effect.

[0057] like Figure 1 As shown, according to some embodiments of the present invention, a contact plate 1211 is further provided in the socket, one end of the contact plate 1211 is connected to the edge of the socket, and the other end extends away from the first end 12, and the contact plate 1211 is suitable for fitting with the second plate 1112.

[0058] Specifically, one end of the contact plate 1211 can be connected to the edge of the socket, and the other end can extend away from the first end 12. A non-straight angle is provided between the contact plate 1211 and the first end 12. The surface of the contact plate 1211 facing the second end 11 is configured as a first surface, and the surface of the second plate 1112 facing the first end 12 is configured as a second surface. The first surface is suitable for fitting with the second surface. In this way, the contact area between the first limiting portion and the second limiting portion 111 can be increased, the limiting effect can be improved, and it is beneficial to improve the convenience of the limiting connection between the first limiting portion and the second limiting portion 111.

[0059] It should be pointed out that in the utility model, the first plate 1111, the second plate 1112, the third plate 1113 and the contact plate 1211 can be flat plates or curved plates with an arc, and the first limiting portion and the second limiting portion 111 are not limited in shape and size. Any structural form that can limit the movement of the first end 12 and the second end 11 in the first direction by limiting the position in the second direction should be within the scope of protection of this application.

Figure 1 and Figure 2 The first limiting portion structure can achieve limiting connection with the second limiting portion 111.

[0061] like Figure 1-Figure 4 As shown, according to the energy storage device of the embodiment of the second aspect of the utility model, the energy storage device includes: the electrical connector 1 described in any one of the above embodiments. Since the energy storage device according to the embodiment of the second aspect of the utility model includes the electrical connector 1 described in any one of the above embodiments, the electrical connector 1 in the energy storage device is provided with a first limit portion and a second limit portion 111 to improve the vibration resistance of the electrical connector 1, prevent the interlock detection mechanism from reporting a false alarm, and improve the working reliability of the energy storage device.
