[0040] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0041] Please refer to Figure 1 and Figure 2 The protective cover 100 and the electrical connector provided in the embodiment of the present invention can solve the above problems, which will be described in detail below.

[0042] The protective cover 100 is applied to an electrical connector, and includes a base 110 and a cover plate 120 that are rotatably connected;

[0043] One of the base 110 and the cover 120 is formed with a protrusion 130 , and the other is formed with a recess 140 and a guide portion 150 . The protrusion 130 is used to be accommodated in the recess 140 or to abut against the guide portion 150 .

[0044] During use, when the cover 120 is attached to the base 110 or is fully open, the protrusion 130 can be accommodated in the recessed portion 140 for positioning. In the process of the cover 120 opening the base 110, the protrusion 130 can be supported by the guide portion 150, and will not be easily displaced during the opening process, so that the cover 120 can hover relative to the base 110, thereby improving the convenience of use while reducing the difficulty of assembly.

[0045] In this embodiment, the protrusion 130 is formed on the cover plate 120 , the recess 140 is formed on the base 110 , and the protrusion 130 and the support portion are respectively located at one end where the cover plate 120 and the base 110 are rotatably connected.

[0046] refer to Figure 1-Figure 3 The base 110 has an electrical connection hole 113 formed on its surface. The cover 120 is used to cover the electrical connection hole 113. When the cover 120 is in a close fit, it can prevent dust, foreign matter, and water droplets from entering. When work is required, the cover 120 can be opened, thereby leaving the electrical connection hole 113 open.

[0047] refer to Figure 3 and Figure 4 In order to improve the connection stability between the cover plate 120 and the base body 110 , an extension portion 111 may be provided on the base body 110 , and a connection hole 112 may be opened on the extension portion 111 . A rotating shaft 121 may be formed on the cover plate 120 , and the rotating shaft 121 may be rotatably accommodated in the connection hole 112 .

[0048] Specifically, the extension portion 111 extends toward the side close to the cover plate 120 and is perpendicular to the plate surface of the base body 110, thereby reducing the difficulty of demolding. The adapter hole 112 is elongated, allowing the shaft 121 to adaptively move inside the elongated inside of the adapter hole 112.

[0049] In this embodiment, in order to reduce the weight of the base body 110, the base body 110 can be hollowed out, and a support bar is formed on the side of the base body 110 close to the cover plate 120, and the guide portion 150 and the recessed portion 140 are both opened on the support bar. The number of support bars is two, and the two support bars are arranged at intervals.

[0050] Of course, in other embodiments of the present invention, the number of support bars can be one, three, five, eight, etc., and there is no limitation on the specific number of support bars.

[0051] Alternatively, the base 110 may include a connected base body and a support plate 115, with the cover 120 rotatably connected to the support plate 115. Furthermore, the surface area of ​​the support plate 115 may be no less than that of the cover 120, so that the support plate 115 provides sufficient support. Specifically, the extension 111 and the electrical connection hole 113 may be formed on the support plate 115.

[0052] refer to Figure 2 and Figure 3 The raised portion 130 includes a first raised portion 131 and a second raised portion 132 that are spaced apart.

[0053] The first protrusion 131 is used to be accommodated in the recessed portion 140 when the cover plate 120 is attached to the base 110, and is used to be separated from the recessed portion 140 when the cover plate 120 opens the base 110;

[0054] The second protrusion 132 is used to abut against the guide portion 150 or be accommodated in the recessed portion 140 when the cover 120 is attached to or opens the base 110 .

[0055] Specifically, in the fitted state, the first protrusion 131 is accommodated in the recessed portion 140 , and the second protrusion 132 is abutted against the guide portion 150 or accommodated in the recessed portion 140 .

[0056] When the base 110 is opened, force can be applied to rotate the cover 120 relative to the base 110. At this time, the first protrusion 131 will disengage from the recessed portion 140, and the second protrusion 132 will move toward the recessed portion 140 while being pressed against the guide portion 150. During the movement, because there is always a pressing force between the guide portion 150 and the second protrusion 132, the cover 120 can maintain a suspended state relative to the base 110 after the external force is removed; when the cover 120 is rotated to the maximum opening angle relative to the base 110, the second protrusion 132 will be accommodated in the recessed portion 140, thereby improving the relative position stability of the cover 120 and the base 110 under the maximum opening angle.

[0057] It is worth noting that in order to prevent the two protrusions from moving smoothly relative to the recessed portion 140, the corners of the two protrusions may be arc-shaped. Of course, in other embodiments of the present invention, the two protrusions may also be arched.

[0058] refer to Figure 2-Figure 4 The recessed portion 140 includes a limiting groove 141 and an avoidance groove 142 . The guide portion 150 and the avoidance groove 142 are respectively located on both sides of the limiting groove 141 . The limiting groove 141 is used to accommodate the first protrusion 131 or the second protrusion 132 , and the avoidance groove 142 is used to accommodate the first protrusion 131 .

[0059] When the first protrusion 131 disengages the limiting groove 141 during the rotation of the cover plate 120, it also rotates with the cover plate 120. The provision of the avoidance groove 142 reduces the obstruction to the first protrusion 131 during this rotation. Furthermore, the depth of the avoidance groove 142 gradually decreases as it moves away from the limiting groove 141, thereby increasing the forming rate of the avoidance groove 142.

[0060] It is worth noting that the recessed portion 140 may also include a positioning groove 143, which is located at the end of the guide portion 150 away from the limiting groove 141 and the avoidance groove 142. When the cover plate 120 is in contact with the base 110, the second protrusion 132 can be accommodated in the positioning groove 143 to ensure that the relative position of the cover plate 120 and the base 110 is stable in the contact state, and to prevent the cover plate 120 from rotating relative to the base 110 even under slight external force.

[0061] refer to Figure 2-Figure 4 To provide a more effective damping effect when the first protrusion 131 is released from the limiting groove 141, a third protrusion 160 is formed between the limiting groove 141 and the avoiding groove 142. The third protrusion 160 is used to abut the first protrusion 131 when the first protrusion 131 is released from the limiting groove 141. When a worker manually rotates the cover 120 relative to the base 110, the first protrusion 131 releases the limiting groove 141 and moves toward the avoiding groove 142. The abutment of the third protrusion 160 against the first protrusion 131 can provide a certain damping effect to the worker's hand.

[0062] In this embodiment, in order to improve the smoothness of the first protrusion 131 passing through the third protrusion 160, the third protrusion 160 can be made into an arch shape. Of course, in other embodiments of the present invention, the corners of the third protrusion 160 can also be made into a prismatic shape.

[0063] refer to Figure 2-Figure 4 When the cover 120 rotates to the maximum opening angle, the second protrusion 132 enters the limiting groove 141 from the guide portion 150. To improve the damping feeling during this process, a damping portion 170 can be formed between the recessed portion 140 and the guide portion 150. Specifically, the damping portion 170 protrudes from the guide portion 150 and the limiting groove 141.

[0064] It can be understood that when the staff manually drives the cover 120 to rotate so that the second protrusion 132 disengages from the guide part 150 and enters the limiting groove 141, the damping part 170 can support the second protrusion 132, thereby generating a certain damping feeling on the staff's hand.

[0065] Furthermore, the guide portion 150 is a guide arc surface formed on the side of the base 110 close to the cover 120, or formed on the side of the cover 120 close to the base 110. In this embodiment, the guide arc surface is formed on the upper side of the base 110.

[0066] The embodiment of the present invention further provides an electrical connector, comprising a conductor and a protective cover 100 , wherein the conductor is accommodated in a base 110 . The conductor can exchange electricity with the outside world through an electrical connection hole 113 on the base 110 .

[0067] It should be noted that the electrical connector can specifically be a socket or plugboard in daily life, a charging position or charging gun on a new energy vehicle or electrical equipment, a civil or commercial electric meter, etc. There is no limitation on the specific type of the point connector.

[0068] In summary, the protective cover 100 and the electrical connector provided by the embodiments of the present invention have at least the following advantages:

[0069] (1) In the fitted state, the raised portion 130 can be positioned when it is accommodated in the recessed portion 140; in the open state, the raised portion 130 can also be abutted against the guide portion 150, so that it will not be easily displaced during the opening process, so that the cover 120 can be suspended relative to the base 110, thereby improving the ease of use while reducing the difficulty of assembly.

[0070] (2) The first protrusion 131 and the second protrusion 132 are respectively accommodated in the limiting groove 141 at the fitting and maximum opening angles, so that the cover 120 has better stability relative to the base 110 at the fitting and maximum opening angles.

[0071] (3) By forming an avoidance groove 142 on the side of the limiting groove 141 away from the guide portion 150, the first protrusion 131 that is separated from the limiting groove 141 can be avoided, thereby avoiding affecting the smoothness of the opening of the cover plate 120.

[0072] (4) By forming a third protrusion 160 and a damping portion 170 on both sides of the limiting groove 141, the damping feeling when the first protrusion 131 and the second protrusion 132 enter or leave the limiting groove 141 can be improved, and the stability of the first protrusion 131 and the second protrusion 132 when they are accommodated in the limiting groove 141 can be better.

[0073] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
