[0047] In order to make the technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0048] Figure 1 This is a schematic diagram of the structure of a charging gun provided by an embodiment of the utility model. Figure 1 An embodiment of the utility model provides a charging gun, which includes a cable fixing structure 1, a cable 2 and a shell 3, wherein the cable fixing structure 1 is sleeved on the cable 2, and the cable fixing structure 1 is detachably arranged on the shell 3, so that one end of the cable 2 can be fixed in the shell 3 by using the cable fixing structure 2.

[0049] Figure 2 An exploded view of a charging gun provided in an embodiment of the utility model, Figure 3 This is a partial cross-sectional view of a charging gun provided by an embodiment of the utility model. Figure 2 and Figure 3 The cable fixing structure 1 has a connecting passage 101 parallel to the axis of the cable 2 and a recess 102 located on the outer wall. The inner wall of the shell 3 has a hollow cylinder 31, and the hollow cylinder 31 can pass through the recess 102 and the connecting passage 101.

[0050] When the cable 2 is fixed to the housing 3, the fastener 4 can directly penetrate the hollow cylinder 31 without passing through the cable fixing structure 1. Therefore, the charging gun provided by the embodiment of the utility model has a simple and convenient installation process, and the operation of personnel saves time and effort.

[0051] See also Figure 2 The fastener 4 can be a bolt, and the number can be three. Of course, the number of the fasteners 4 can also be more or less, and can be selectively set according to actual conditions, and is not specifically limited in the embodiment of the utility model.

[0052] The structure of the charging gun provided in the embodiment of the utility model is described in detail below:

[0053] In some embodiments, see Figure 4 and Figure 5 ,in Figure 4 A schematic diagram of a cable fixing structure provided by an embodiment of the utility model. Figure 5 An exploded view of a cable fixing structure provided in an embodiment of the utility model, the cable fixing structure 1 includes a locking member 11 and a ring sleeve 12, wherein the locking member 11 and the ring sleeve 12 are both sleeved on the cable 2, the locking member 11 has a plurality of claws 111 arranged around the cable 2, and the ring sleeve 12 is detachably arranged on the periphery of the plurality of claws 111.

[0054] In this way, when the fastener 4 enters the hollow cylinder 31, the locking member 11 will squeeze the ring sleeve 12, causing the ring sleeve 12 to deform and squeeze the multiple claws 111, so that the multiple claws 111 abut against the circumference of the cable 2, thereby radially compressing the cable 2 to achieve fixation of the cable 2.

[0055] In some embodiments, see Figure 6 ,in Figure 6 This is a schematic structural diagram of a locking member provided in an embodiment of the utility model. The locking member 11 further includes a clamping ring 112 and a sealing ring 113 .

[0056] The clamping ring 112 is connected to the sealing ring 113 and both are sleeved on the cable 2, and the plurality of claws 111 are arranged on the side of the clamping ring 112 away from the sealing ring 113. In other words, the clamping ring 112 and the sealing ring 113 form an integral structure, so that the locking member 11 can not only cooperate with the ring sleeve 12 to fix the cable 2, but also play a role in sealing the gap between the cable 2 and the housing 3.

[0057] Compared with the related art which uses claws to fix the cable 2 and uses a cable sealing ring to seal the gap between the cable 2 and the shell 3, the locking piece 11 provided by the utility model only requires a single part to achieve the functions of fixing the cable and sealing the gap between the cable and the shell, thereby reducing the number of parts required to prepare the charging gun and reducing material costs.

[0058] Continue to see Figure 6 The diameter of the sealing ring 113 is greater than the diameter of the clamping ring 112 to ensure that the sealing ring 113 is large enough to seal the gap between the cable 2 and the housing 3 .

[0059] For example, see Figure 6 The outer periphery of the sealing ring 113 is in a threaded structure and is in interference contact with the inner wall of the housing 3 .

[0060] In the embodiment of the utility model, in order to ensure the strength and toughness of the clamping ring 112, the material of the clamping ring 112 can be plastic; in order to ensure that the sealing ring 113 can achieve the sealing function, the material of the sealing ring 113 can be a thermoplastic elastomer material, such as rubber.

[0061] During the preparation of the locking member 11 , the clamping ring 112 may be firstly injection molded, and then the sealing ring 113 may be secondary injection molded on the end surface of the clamping ring 112 away from the plurality of claws 111 using a secondary injection molding process to form a single integral part.

[0062] In some embodiments, see Figure 6 The sealing ring 113 has an elastic through hole 1131, which is formed as a communication channel 101 for the hollow cylinder 31 to pass through. At the same time, the elastic through hole 1131 is not only elastic, but also has a hole diameter smaller than the cross-sectional diameter of the hollow cylinder 31, so that when the hollow cylinder 31 passes through the elastic through hole 1131, there is no gap between the hollow cylinder 31 and the elastic through hole 1131, that is, there is interference contact between the hollow cylinder 31 and the inner wall of the elastic through hole 1131, so as to ensure the sealing of the charging gun.

[0063] In the embodiment of the present invention, the number of the elastic through holes 1131 can be multiple, and the multiple elastic through holes 1131 are arranged on the sealing ring 113 at intervals. Figure 6 The number of the elastic through holes 1131 may be six, and the six elastic through holes 1131 are arranged on the sealing ring 113 at intervals.

[0064] In some embodiments, see Figure 6The locking member 11 also has an extension ring 114, wherein the extension ring 114 is sleeved on the cable 2 and is located on the side of the sealing ring 113 away from the clamping ring 112, and can be used to protect the cable 2 to prevent the cable 2 from bending or wearing, thereby realizing the function of the cable sheath.

[0065] Compared with the related art of using claws to fix cables, using cable sealing rings to seal the gap between cables and shells, and using cable sheaths to protect cables from bending and friction damage, the locking piece 11 provided by the utility model only requires a single part to achieve three different functions of fixing cables, sealing the gap between cables and shells, and protecting cables. It not only reduces the number of parts for preparing the charging gun and reduces material costs, but also simplifies the assembly process and reduces assembly difficulty and labor costs.

[0066] Continue to see Figure 6 , the diameter of the extension ring 113 is smaller than the diameter of the clamping ring 112. In other words, the diameter of the extension ring 113 does not need to be too large, and only needs to be sleeved on the cable 2.

[0067] In some embodiments, see Figure 4 and Figure 5 The outer peripheral wall of the clamping ring 112 has a first groove 1121 , and the outer peripheral wall of the ring sleeve 12 has a second groove 121 . The first groove 1121 and the second groove 121 form a recess 102 for the hollow cylinder 31 to pass through.

[0068] Based on the above structure, see Figure 4 and Figure 5 The cable fixing structure 1 further includes a gland 13, which is sleeved on the cable 2 and detachably arranged on a side of the locking member 11 away from the ring sleeve 12. The gland 13 can be used to press the locking member 11. At the same time, the gland 13 can also play a decorative role, and it cooperates with the housing 3 to make the charging gun more beautiful.

[0069] In some embodiments, see Figure 5 The gland member 13 has a limiting through hole 131 , which is connected to the connecting channel 101 and can play the role of the limiting fastener 4 .

[0070] In the embodiment of the present utility model, see Figure 3 One end of the fastener 4 passes through the limiting through hole 1131 and enters into the hollow cylinder 31 , and the other end is limited in the limiting through hole 131 .

[0071] In some embodiments, see Figure 5 There are multiple communicating channels 101 , and the gland member 13 further has a sealing column 132 , which is detachably disposed in at least one communicating channel 101 .

[0072] By providing the sealing column 132 , when the fastener 4 is screwed in, the sealing column 132 can squeeze the locking member 11 , and then the locking member 11 squeezes the ring sleeve 12 , so that the plurality of claws 111 abut against the circumference of the cable 2 , thereby compressing the cable 2 in the radial direction.

[0073] In an embodiment of the utility model, the number of connecting channels 101 (i.e., elastic through holes 1131) is equal to the sum of the number of sealing columns 132 and the number of recesses 102, that is, a portion of the connecting channels 101 is used to penetrate the sealing columns 132, and another portion of the connecting channels 101 is used to communicate with the recesses 102 and penetrate the hollow cylinder 31.

[0074] In some embodiments, see Figure 7 The inner wall of the shell 3 also has a fixing piece 32 , and the bottom surface of the cable fixing structure 1 (i.e., the side of the ring sleeve 12 away from the locking piece 11 ) abuts against the fixing piece 32 , so that the cable fixing structure 1 can be fixed in the shell 3 by the fixing piece 32 .

[0075] See also Figure 7 The number of the fixing members 32 can be multiple, and the multiple fixing members 32 are arranged on the inner wall of the shell 3 at intervals to facilitate the firm fixation of the cable fixing structure 1.

[0076] In a possible example, the charging gun provided by the embodiment of the utility model can be installed as follows: first, the pressure cover 13, the locking piece 11 and the ring set 12 are sequentially mounted on the cable 2; then, the pressure cover 13, the locking piece 11 and the ring set 12 are placed into the shell 3, so that the hollow cylinder 31 of the shell 3 is inserted into the recess 102 and the connecting channel 101 in sequence; then, the fastener (i.e., bolt) 4 is screwed into the pressure cover 13 and the central control column 31 for locking. During the screwing process of the fastener 4, the pressure cover 13 presses the locking piece 11 and the ring set 12, so that the multiple claws 111 abut against the circumference of the cable 2, thereby achieving the locking and fixation of the cable 2 and the sealing between the cable 2 and the shell 3.

[0077] The embodiment of the utility model further provides a charging device, which includes the charging gun involved in the above embodiment.

[0078] Based on the charging gun involved in the above embodiment, the installation process is simple and convenient, and the operation of personnel saves time and effort.

[0079] Furthermore, the charging device may be a charging pile.
