[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] like Figures 1 to 5As shown, this embodiment provides a connection cover for a female end, and the connection cover for a female end includes a housing 1 and a control rod 2. The housing 1 has a first elastic buckle 11 and a second elastic buckle 12 that are correspondingly arranged; the control rod 2 is detachably arranged on the housing 1, and the control rod 2 has a snap-on protrusion 21, and the control rod 2 is rotatably arranged, and the snap-on protrusion 21 can be snap-on with the first elastic buckle 11 or the second elastic buckle 12, so as to connect the housing 1 with the male end through the control rod 2; the control rod 2 has a normal installation condition and a reverse installation condition, and in the normal installation condition, the control rod 2 rotates toward one side of the housing 1, and the snap-on protrusion 21 is snap-on with the first elastic buckle 11; in the reverse installation condition, the control rod 2 rotates toward the other side of the housing 1, and the snap-on protrusion 21 is snap-on with the second elastic buckle 12.

[0029] The connection cover for the female end of the present invention is used, such as Figure 2 and Figure 3 As shown, when the control rod 2 is in the normal working state, the operator turns the control rod 2 toward one side of the housing 1 to engage the engaging protrusion 21 with the first elastic buckle 11, thereby achieving the purpose of connecting the housing 1 with other components through the control rod 2 and finally connecting with the male end; or Figure 4 and Figure 5 As shown, when the control rod is in the reverse installation condition, the first elastic buckle 11 is pressed at this time to disengage the clamping protrusion 21 from the first elastic buckle 11, and then the control rod 2 is removed and reversely installed on the housing 1, and then the operator turns the control rod 2 toward the other side of the housing 1, so that the clamping protrusion 21 is clamped with the second elastic buckle 12, thereby achieving the purpose of connecting the female end and the male end connected to the housing 1 through the control rod 2. This setting method improves the versatility of the connection cover for the female end. With the connection cover for the female end of the present invention, the control rod 2 can be installed in the forward and reverse directions, and the position of the control rod 2 can be adjusted according to actual conditions, thereby effectively avoiding the interference of the control rod 2 with other components after buckling, improving the versatility of the connection cover for the female end, and effectively solving the problem that the control rod 2 of the connection cover for the female end in the prior art cannot change the buckling direction, resulting in poor versatility. Among them, the control rod 2 can connect the female end and the male end connected to the housing 1 through a slide.

[0030] It should be noted that the housing 1 can be installed at the female end or the male end. In this solution, the housing 1 is installed at the female end.

[0031] In some embodiments, Figure 1As shown, the first elastic buckle 11 has a first clamping groove 111, and the second elastic buckle 12 has a second clamping groove 121. In the normal installation condition, the clamping protrusion 21 is located in the first clamping groove 111 and abuts against the inner wall of the first clamping groove 111; such a setting can achieve the purpose of clamping the control rod 2 on the housing 1; similarly, in the reverse installation condition, the clamping protrusion 21 is located in the second clamping groove 121 and abuts against the inner wall of the second clamping groove 121, and such a setting is also for the purpose of clamping the control rod 2 on the housing 1.

[0032] In this embodiment, the side wall of the housing 1 has a first limiting protrusion 13 and a second limiting protrusion 14. In the normal installation condition, when the clamping protrusion 21 is buckled with the first elastic buckle 11, the control rod 2 abuts against the first limiting protrusion 13, thereby limiting the position of the control rod 2; similarly, in the reverse installation condition, when the clamping protrusion 21 is buckled with the second elastic buckle 12, the control rod 2 abuts against the second limiting protrusion 14, thus limiting the position of the control rod 2, ensuring that the control rod 2 is in a reasonable position, and improving the stability and reliability of the control rod 2 after buckling.

[0033] Optionally, the second limiting protrusion 14 is a limiting column, and the limiting column is obliquely arranged on the side wall of the housing 1 .

[0034] Specifically, Figure 1 As shown, the first elastic buckle 11 includes an elastic plate 112 and a pressing plate 113 disposed on the elastic plate 112. A first clamping groove 111 is formed between the elastic plate 112 and the housing 1, and the elastic plate 112 has an abutting surface 1121. In this way, in the normal installation condition, when the clamping protrusion 21 is buckled with the first elastic buckle 11, the end face of the control rod 2 abuts against the abutting surface 1121, thereby ensuring the stability of the control rod 2 after buckling.

[0035] Similarly, the structure of the second elastic buckle 12 is the same as that of the first elastic buckle 11. In the reverse installation condition, when the locking protrusion 21 is engaged with the second elastic buckle 12, the end face of the control rod 2 abuts against the abutting surface 1121 of the second elastic buckle 12, thereby ensuring the stability of the control rod 2 after engagement.

[0036] Specifically, the control rod 2 is U-shaped, and includes a first side plate 22, a second side plate 23 and an operating plate 24. The first side plate 22 is connected to the second side plate 23 through the operating plate 24, and the first side plate 22 and the second side plate 23 are respectively detachably and rotatably connected to the two side walls of the housing 1, which effectively ensures the stability of the control rod 2 when rotating. The operating plate 24 has a clamping protrusion 21 and is located above the housing 1. The first side plate 22 and the second side plate 23 connect the female end connected to the housing 1 with the male end through a sliding sheet, that is, the housing 1 is connected to other components through the control rod 2, and finally connected to the male end.

[0037] Furthermore, the housing 1 has a first rotating shaft 15 and a second rotating shaft, wherein the first rotating shaft 15 and the second rotating shaft are respectively arranged on two corresponding side walls of the housing 1, the first side plate 22 is rotatably connected to the housing 1 via the first rotating shaft 15, and the second side plate 23 is rotatably connected to the housing 1 via the second rotating shaft. With such an arrangement, the stability of the first side plate 22 and the second side plate 23 during rotation can be improved, and the control rod 2 can rotate around the first rotating shaft 15 and the second rotating shaft.

[0038] Specifically, the first side plate 22 has connecting teeth 221, and the connecting teeth 221 are arranged along the circumference of the first rotating shaft 15, so that the connecting teeth 221 can engage with the teeth on the slide to connect the female end connected to the outer shell 1 with the male end, thereby realizing the connection of the outer shell 1 and other components through the control rod 2, and finally connecting with the male end.

[0039] In this embodiment, the first side plate 22 and the second side plate 23 both have reinforcing ribs 222. The reinforcing ribs 222 are provided to enhance the structural strength of the first side plate 22 and the second side plate 23.

[0040] Specifically, the housing 1 includes a first side wall 16, a second side wall 17 and a top wall 18. The first side wall 16 is connected to the second side wall 17 through the top wall 18, wherein the top wall 18 has a first elastic buckle 11 and a second elastic buckle 12, and the control rod 2 is detachably and rotatably arranged on the first side wall 16 and the second side wall 17. This arrangement facilitates the buckling of the control rod 2 and the housing 1.

[0041] This embodiment also provides a vehicle connector, comprising a male end, a female end and the connection cover for the female end in the above scheme, wherein the housing 1 of the connection cover for the female end is installed on the female end and connected to the male end through a control rod 2. Figure 2 and Figure 3 As shown, when the control rod 2 is in the normal working state, the operator turns the control rod 2 toward one side of the housing 1 to engage the engaging protrusion 21 with the first elastic buckle 11, thereby achieving the purpose of connecting the housing 1 and the male end through the control rod 2; or Figure 4 and Figure 5As shown, when the control rod is in the reverse installation condition, the first elastic buckle 11 is pressed to disengage the clamping protrusion 21 from the first elastic buckle 11, and then the control rod 2 is removed and reversely installed on the housing 1. Then the operator turns the control rod 2 toward the other side of the housing 1, so that the clamping protrusion 21 is clamped with the second elastic buckle 12, thereby achieving the purpose of connecting the housing 1 and the male end through the control rod 2. This arrangement improves the versatility of the connection cover for the female end. With the vehicle connector of the present invention, the control rod 2 can be installed forward and reversely, and the position of the control rod 2 can be adjusted according to actual conditions, thereby effectively avoiding interference between the control rod 2 and other components after buckling, improving the versatility of the connection cover for the female end, and effectively solving the problem that the control rod 2 for the connection cover of the female end in the prior art cannot change the buckling direction, resulting in poor versatility.
