Technical Field

[0001] The utility model relates to the technical field of charging guns, and in particular to a tail cable sealing and fixing assembly for a mode two charging gun and a charging gun. Background Art

[0002] At present, the charging guns for new energy electric vehicles mainly include mode 2 charging guns, mode 3 AC charging guns and mode 4 charging guns. The charging gun terminals are connected to the cables inside, and the tail of the charging gun housing needs to be isolated and sealed by the tail assembly.

[0003] In the tail assembly, the tail is an important component, which is usually split from the tail of the charging gun housing. In the prior art, the tail cover is usually obtained in the following two ways. One is to cut a complete shell tail as a tail cover from the tail of the charging gun housing. The second is to divide the cut complete shell tail into two to form two separate tail covers. When using the complete shell tail as a tail cover to cooperate with other parts of the tail assembly to seal the tail of the charging gun housing, at least one cable fixing clip needs to be equipped in the other parts of the tail assembly, which increases the cost and structural complexity; because the tail cable sealing sleeve requires an interference fit, it is usually difficult to assemble and inefficient, which increases the assembly cost.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-5, the present application discloses a sealing and fixing assembly for a tail cable 14 of a mode 2 charging gun, comprising a charging gun housing 11, a cable sealing sleeve 12, and a tail cover 13;

[0030] The tail cover 13 is detachably fixed to the charging gun housing 11, and a receiving space is formed between the tail cover 13 and the charging gun housing 11, and the receiving space is used to receive the cable sealing sleeve 12 and part of the cable 14;

[0031] The cable sealing sleeve 12 is sleeved on the cable 14;

[0032] See also Figure 2 and Figure 3 The charging gun housing 11 is provided with a avoiding through hole 111 and a first limiting groove 112, and the first limiting groove 112 is located in the accommodating space; the cable 14 passes through the avoiding through hole 111 and enters the interior of the charging gun housing; the cable sealing sleeve 12 is arranged in the first limiting groove 112, for limiting the cable 14.

[0033] In this embodiment, by sleeve-mounting the cable sealing sleeve 12 on the cable 14 and setting the sealing ring of the cable 14 in the first limiting groove 112, the sealing ring of the cable 14 is limited and then the cable 14 is limited, so that the sealing and fixing assembly of the tail cable 14 for the mode two charging gun has a simple structure, is easy to assemble and has low cost.

[0034] In some embodiments, the tail cover 13 is provided with a second limiting groove, the second limiting groove is located in the accommodating space, and the second limiting groove and the first limiting groove 112 are enclosed to form a limiting empty groove, and the cable sealing sleeve 12 is limited to the limiting empty groove. In this embodiment, the position of the cable sealing sleeve 12 is limited by the limiting empty groove formed by the first limiting groove and the second limiting groove, thereby limiting the position of the cable 14, which has a simple structure, is easy to process and produce, and reduces production costs.

[0035] In some embodiments, the cable sealing sleeve 12 is made of an elastic material, such as rubber or other elastic materials, which are abundant in raw materials and suitable for assembly.

[0036] See also Figure 3 Furthermore, in order to improve the stability of the cooperation between the cable 14 and the sealing ring of the cable 14, the cable sealing sleeve 12 is provided with an interference protrusion 121 on the inner surface where the cable 14 is fixed.

[0037] In some embodiments, in order to improve the stability of the sealing ring of the charging gun housing 11 and the cable 14, the outer surface of the cable sealing sleeve 12 is provided with a fixing groove 122; the charging gun housing 11 is provided with a fixing protrusion 113 that cooperates and fixes with the fixing groove 122. Specifically, the fixing groove 122 is circumferentially connected end to end and is arranged on the outer surface of the cable sealing sleeve 12. In other embodiments, the fixing groove 122 and the fixing protrusion 113 can also be arranged at intervals and cooperate with each other.

[0038] See also Figure 1 and Figure 4 In some embodiments, in order to fix the tail cover 13 on the charging gun housing 11, bolt holes 132 are provided on the tail cover 13 and the charging gun housing 11, and the tail cover 13 and the charging gun housing 11 are fixed by bolts 133.

[0039] See also Figure 1 and Figure 4 Specifically, in the present embodiment, the tail cover 13 is formed by partially splitting the tail portion of the charging gun housing, and when the tail cover 13 is partially split from the tail portion of the charging gun housing, half of the tail portion of the charging gun housing is split.

[0040] It should be noted that, in the prior art, the acquisition of the tail cap 13 generally includes the following two methods. One is to cut out a complete shell tail portion as the tail cap 13 from the overall tail of the charging gun housing 11. The second is to divide the cut complete shell tail portion into two to form two separate tail caps 13. When using the complete shell tail portion as the tail cap 13 to cooperate with other parts of the tail cap 13 assembly to seal the tail of the charging gun housing 11, at least one cable 14 fixing clip needs to be provided in the other parts of the tail cap 13 assembly, which increases the cost and structural complexity. When using two separate tail caps 13 to cooperate with other parts of the tail cap 13 assembly to seal the tail of the charging gun housing 11, the two separate tail caps 13 increase the cost and structural complexity.

[0041] Compared with the prior art in which a complete shell tail is cut out of the tail of the charging gun housing 11 as a whole as the tail cover 13, the tail cover 13 proposed in this embodiment is formed by partially splitting the tail of the charging gun housing 11. In this embodiment, the interior and exterior of the charging gun housing 11 are separated and sealed by the accommodation space enclosed by the charging gun housing 11 and the tail cover 13. The tail cover 13 is fixed to the charging gun housing 11 by screws, and the sealing ring of the cable 14 is limited in the limited groove formed by the first limiting groove 112 provided on the charging gun housing 11 and the second limiting groove provided on the tail cover 13, thereby limiting the cable 14. The structure is simple, the assembly and disassembly is convenient, and the processing cost and assembly cost are saved.

[0042] It should be noted that, in this embodiment, partial splitting is a concept opposite to the overall splitting in the prior art. In the prior art, a complete shell tail is cut out from the tail of the charging gun shell 11 as a tail cover 13, which belongs to the overall splitting method.

[0043] In some preferred embodiments, when the tail cover 13 is partially split from the tail of the charging gun housing 11, half of the tail of the charging gun housing 11 is split. Further, when half of the tail of the charging gun housing 11 is split, it is split from the lower half, upper half, left half, or right half of the tail of the charging gun housing 11.

[0044] See also Figure 1 and Figure 4 In some embodiments, the first limiting groove 112 is a U-shaped structure, and a through hole 111 for passing the wire is opened at the tail of the U-shaped structure.

[0045] The present application also discloses a charging gun, including a sealing and fixing assembly for a tail cable 14 of a mode 2 charging gun. Some beneficial effects of the charging gun are the same as those of the sealing and fixing assembly for a tail cable 14 of a mode 2 charging gun, and will not be described in detail here.

[0046] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
