[0006] The clamping component includes a retaining ring and an elastic claw. The retaining ring is sleeved on the cable, and the elastic claw is connected to the retaining ring and located on the periphery of the cable. The elastic claw abuts against the cavity wall of the through cavity, so that the elastic claw deforms to clamp the cable.

[0007] In one embodiment, the fixing component includes a tail cap and a cable sheath. The tail cap has the through cavity, the fixing ring is located on one side of the tail cap, and the cable sheath is located on the other side of the tail cap and is at least partially fitted over the cable.

[0013] In one embodiment, the sleeve body is provided with a first latching protrusion, and the cable sheath is provided with a latching hole, wherein the first latching protrusion is detachably located within the latching hole.

[0014] In one embodiment, the elastic claws include a plurality of them, which are spaced apart along the inner periphery of the fixing ring.

[0015] In one embodiment, the elastic claw includes a connecting segment and a second protrusion. One end of the connecting segment is connected to the fixing ring, and the second protrusion is connected to the other end of the connecting segment and is located on the side of the connecting segment opposite to the fixing component.

[0016] In one embodiment, the cross-sectional area of ​​the connecting segment gradually decreases from the end closer to the fixing ring to the end farther away from the fixing ring.

[0017] This utility model also proposes a charging gun, the charging gun comprising:

[0018] The housing has a mounting cavity; and

[0039] Please refer to the reference. Figures 1 to 4As shown, this utility model proposes a tail clamping device 100, which includes a fixing component 1 and a clamping component 2. The fixing component 1 has a through cavity 13 for the cable 3 to pass through, and at least part of the cavity wall of the through cavity 13 is inclined. The clamping component 2 includes a fixing ring 21 and an elastic claw 22. The fixing ring 21 is sleeved on the cable 3, and the elastic claw 22 is connected to the fixing ring 21 and located on the periphery of the cable 3. The elastic claw 22 abuts against the cavity wall of the through cavity 13, so that the elastic claw 22 deforms to clamp the cable 3.

[0040] In this embodiment, the fixing component 1 has a through cavity 13, through which the cable 3 passes when clamping it. The clamping component 2 includes a fixing ring 21 and an elastic claw 22. When clamping the cable 3, the cable 3 also passes through the fixing ring 21, and the elastic claw 22 is connected to the fixing ring 21 and located on the periphery of the cable 3. During assembly, the clamping component 2 and the fixing component 1 are fitted onto the cable 3. Then, the clamping component 2 and the fixing component 1 are moved closer to each other so that the elastic claw 22 gradually extends into the through cavity 13 of the fixing component 1. The elastic claw 22 has elastic deformation capability, and part of the cavity wall of the through cavity 13 is inclined. Under the pressure of the cavity wall of the through cavity 13, the elastic claw 22 located on the periphery of the cable 3 deforms inward, thereby clamping the cable 3 and fixing and limiting it. In this way, the clamping component 2 can directly fix and clamp the cable 3 during the assembly process of the tail clamping device 100, effectively improving the assembly efficiency.

[0041] Specifically, the fixing ring 21 has a ring structure, and the cable 3 passes through the ring of the fixing ring 21. An inclined surface is formed in at least a portion of the cavity wall of the through cavity 13 in the axial direction. This inclined surface gradually tapers inward from the end near the clamping member 2 towards the end away from the clamping member 2, that is, the radial dimension of the through cavity 13 gradually decreases in this direction. When the tail clamping device 100 is assembled, the end of the elastic claw 22 facing away from the fixing ring 21 extends into the through cavity 13; as the fixing assembly 1 and the fixing ring 21 approach each other, the elastic claw 22 comes into contact with the inclined surface. Due to the inward taper of the inclined surface, the elastic claw 22 is subjected to pressure and undergoes elastic deformation radially inward, thereby achieving clamping and fixing of the cable 3. By setting at least a portion of the cavity wall of the through cavity 13 as an inclined surface, the inclined surface directly interacts with the elastic claw 22, allowing the elastic claw 22 to produce controllable elastic deformation without additional tools or fasteners, thereby achieving reliable clamping of the cable 3.

[0042] Understandably, the degree of deformation of the elastic claw 22 is related to its depth of insertion into the cavity 13. The deeper it penetrates into the cavity 13, the greater the deformation of the elastic claw 22, and the greater the clamping force on the cable 3. During assembly, the insertion depth of the elastic claw 22 into the cavity 13 of the fixing component 1 can be determined by whether the fixing component 1 and the fixing ring 21 abut. When the fixing component 1 and the fixing ring 21 approach each other until they abut, the elastic claw 22 is fully inserted. This avoids the elastic claw 22 being inserted too shallowly or too deeply, thereby effectively controlling the clamping force of the elastic claw 22 on the cable 3. The application scenarios of this tail clamping device 100 include, but are not limited to, cable clamping of charging guns, electrical equipment, electrical connectors, etc.

[0043] In embodiments of this utility model, such as Figures 2 to 4 As shown, the fixing component 1 includes a tail cover 11 and a cable sheath 12. The tail cover 11 has a through cavity 13. A fixing ring 21 is located on one side of the tail cover 11, and the cable sheath 12 is located on the other side of the tail cover 11 and is at least partially fitted onto the cable 3.

[0044] In this embodiment, the end cap 11 has an axially through-hole 13 for the cable 3 to pass through. The retaining ring 21 is fitted onto the cable 3 from one side of the end cap 11, and the cable sheath 12 is fitted onto the cable 3 from the other side of the end cap 11. The cable sheath 12 has a certain elasticity and can be tightly connected with the cable 3 to ensure the sealing of the clamping device of the end cap 11 and prevent moisture or impurities from seeping in from the gap between the cable 3 and the retaining component 1.

[0045] In actual implementation, the tail cap 11 is made of plastic and serves as a support structure for fixing the clamp 2 and for connecting the cable sheath 12 to the installation structure. The cable sheath 12 is made of plastic or rubber and is at least partially connected to the tail cap 11. One end extends axially toward the side of the tail cap 11 away from the fixing ring 21 and covers the cable 3 after it extends out of the cavity 13.

[0046] In embodiments of this utility model, such as Figures 2 to 4 As shown, the tail cap 11 includes a sleeve 111, a mounting platform 112, and a clamping part 113. The sleeve 111 has a through cavity 13. The mounting platform 112 is arranged around one end of the sleeve 111, and the fixing ring 21 abuts against the mounting platform 112. The clamping part 113 is connected to the mounting platform 112 and is arranged opposite to the sleeve 111. The clamping part 113, the mounting platform 112, and the sleeve 111 form a clamping groove 114, and at least a portion of the cable sheath 12 is confined in the clamping groove 114.

[0047] In this embodiment, the sleeve 111 is a tubular portion of the tail cap 11, with an axially extending cavity 13 inside for the cable 3 to pass through. The mounting platform 112 is wrapped around one end of the sleeve 111 and extends radially outwards. When the fixing assembly 1 is assembled, the end face of the mounting platform 112 abuts against the end face of the fixing ring 21, thus positioning the fixing ring 21 axially. The clamping part 113 is located outside the mounting platform 112 and is spaced apart from and opposite to the outer wall of the sleeve 111, forming a clamping groove 114 with the mounting platform 112 and the sleeve 111. The opening of the clamping groove 114 faces the insertion direction of the cable sheath 12. A portion of the cable sheath 12 is inserted into and located in the clamping groove 114, connecting the cable sheath 12 to the tail cap 11.

[0048] In actual implementation, after assembly, the clamping part 113 and the cavity wall of the mounting cavity 51 press against each other, further clamping the cable sheath 12 located in the clamping groove 114, so as to prevent the cable sheath 12 from loosening from the tail cap 11.

[0049] In embodiments of this utility model, such as Figure 2 As shown, the sleeve 111 is provided with a first locking protrusion 1111, and the cable sheath 12 is provided with a locking hole 121. The first locking protrusion 1111 is detachably located within the locking hole 121.

[0050] In this embodiment, the outer wall of the sleeve 111 is provided with a first latching protrusion 1111, and a corresponding latching hole 121 is provided at the corresponding position of the cable sheath 12. The shape and size of the latching hole 121 are adapted to the first latching protrusion 1111. After the cable sheath 12 is inserted into the clamping groove 114, the first latching protrusion 1111 engages with the latching hole 121, forming a detachable limiting fit between the first latching protrusion 1111 and the latching hole 121, thereby realizing a detachable connection between the cable sheath 12 and the tail cap 11.

[0051] Optionally, multiple first protrusions 1111 and holes 121 can be provided to ensure the stability of the cable sheath 12 and the connection.

[0052] In embodiments of this utility model, such as Figure 2 As shown, the elastic claws 22 include multiple elastic claws 22, which are spaced apart along the inner periphery of the fixing ring 21.

[0053] In this embodiment, multiple elastic claws 22 are arranged at intervals along the inner circumferential side of the fixing ring 21, and the multiple elastic claws 22 together form a channel through which the cable 3 can pass. When the fixing component 1 is installed in place, each elastic claw 22 retracts inward synchronously, thereby clamping the cable 3 at multiple points, improving the uniformity of force on the cable 3, and realizing stable control of the cable 3.

[0054] In embodiments of this utility model, such as Figures 2 to 4As shown, the elastic claw 22 includes a connecting section 221 and a second protrusion 222. One end of the connecting section 221 is connected to the fixing ring 21, and the second protrusion 222 is connected to the other end of the connecting section 221 and is located on the side of the connecting section 221 facing away from the fixing component 1.

[0055] In this embodiment, the connecting segment 221 is a long, elastic arm, with one end connected to the fixing ring 21 and the other end suspended, forming a cantilever structure. The suspended end of the connecting segment 221 is provided with a second locking protrusion 222, located on the side of the connecting segment 221 facing away from the fixing component 1, i.e., the second locking protrusion 222 is located on the surface of the connecting segment 221 facing away from the end face of the fixing component 1. When the cable 3 passes through the central channel formed by multiple elastic claws 22, the second locking protrusion 222 directly faces the surface of the cable 3. When the fixing component 1 is installed in place and the connecting segment 221 is pushed inward by the inclined surface of the cavity 13, the second locking protrusion 222 moves inward and presses against the outer periphery of the cable 3, thus clamping and fixing the cable 3. Optionally, the second locking protrusion 222 is a boss, a protrusion point, or a wedge-shaped protrusion; the fixing ring 21, the connecting segment 221, and the second locking protrusion 222 are integrally formed.

[0056] Optionally, the cross-sectional area of ​​the connecting segment 221 gradually decreases from the end closer to the fixing ring 21 to the end farther away from the fixing ring 21. This ensures the connection strength between the connecting segment 221 and the fixing ring 21, while also making the end of the connecting segment 221 farther away from the fixing ring 21 easier to elastically deform inward, and making the clamping of the cable 3 by the second latch 222 more stable.

[0057] like Figure 1 , Figure 5 and Figure 6 As shown, this utility model also proposes a charging gun 200, which includes a housing 5 and a tail clamping device 100. The specific structure of the tail clamping device 100 is as described in the above embodiments. Since this charging gun 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. Among them, the housing 5 is provided with a mounting cavity 51, the tail clamping device 100 is connected to the housing 5, and the elastic claw 22 is used to clamp the cable 3 extending from the mounting cavity 51.

[0058] In this embodiment, the mounting cavity 51 can accommodate electronic components and cables 3, which are connected to external devices via cables 3. Cables 3 extend from the opening of the mounting cavity 51 to connect to the external device. A tail clamping device 100 is connected to the housing 5 and closes the opening, ensuring that cables 3 extend from the mounting cavity 51 only through the tail clamping device 100. Under the elastic clamping of the elastic claws 22, the cables 3 are fixed and limited, preventing them from loosening or falling off during use.

[0059] Optionally, the tail clamping device 100 can be connected to the housing 5 by means of screws or clips.

[0060] In embodiments of this utility model, such as Figure 6 As shown, the cavity wall of the mounting cavity 51 is provided with a first limiting step 511, one side of the fixing ring 21 abuts against the first limiting step 511, and the other side of the fixing ring 21 abuts against the fixing component 1.

[0061] In this embodiment, the tail clamping device 100 is assembled into the mounting cavity 51 to ensure the sealing effect of the opening of the mounting cavity 51 and improve the sealing performance of the mounting cavity 51 at the opening. The first limiting step 511 is a stepped surface protruding outward from the cavity wall of the mounting cavity 51. The first limiting step 511 provides a positioning reference for the assembly of the clamping member 2. When assembling the tail clamping device 100, the clamping member 2 is installed in place when the fixing ring 21 abuts against the first limiting step 511. In this way, the first limiting step 511 and the fixing component 1 together clamp and limit the fixing ring 21 in the axial direction, preventing the clamping member 2 from being displaced in the axial direction within the mounting cavity 51.

[0062] In actual assembly, the retaining ring 21 is first fitted onto the cable 3, and then moved into the mounting cavity 51 until it abuts against the first limiting step 511. Next, the fixing component 1 is fitted onto the cable 3 and pushed into the mounting cavity 51. Due to the limiting effect of the first limiting step 511, the clamping member 2 remains stationary. As the fixing component 1 moves into the mounting cavity 51, the elastic claw 22 gradually extends into the through cavity 13 of the fixing component 1 and clamps and fixes the cable 3. This allows the clamping member 2 to directly fix and hold the cable 3 during the assembly of the tail clamping device 100 to the housing 5, effectively improving assembly efficiency.

[0063] Understandably, the outer diameter of the retaining ring 21 matches the inner diameter of the mounting cavity 51, meaning the retaining ring 21 abuts against the cavity wall of the mounting cavity 51 to further ensure the stability of the clamping member 2's position. Optionally, the fixing assembly 1 can be connected to the housing 5 by means of screws or clips.

[0064] Optionally, such as Figure 1 and Figure 6 As shown, the cavity wall of the mounting cavity 51 is provided with a limiting rib 514, which is arranged along the axial direction of the mounting cavity 51. The fixing ring 21 is provided with a first limiting groove 211, and the fixing component 1 is provided with a second limiting groove 115. The limiting rib 514 is limited in the first limiting groove 211 and the second limiting groove 115.

[0065] In this embodiment, the cavity wall of the mounting cavity 51 has an inwardly protruding limiting rib 514. The shape and size of the first limiting groove 211 of the fixing ring 21 match the cross-sectional shape and size of the limiting rib 514. The shape and size of the second limiting groove 115 of the tail cover 11 also match the cross-sectional shape and size of the limiting rib 514. When assembling the tail clamping device 100, first, the limiting rib 514 is aligned with the first limiting groove 211 of the fixing ring 21 and inserted into the mounting cavity 51. Then, the clamping member 2 is slidably pushed in along the axial direction of the mounting cavity 51 until the fixing ring 21 is installed in place. Subsequently, the limiting rib 514 is aligned with the second limiting groove 115 of the fixing component 1, and the fixing component 1 is slidably inserted along the axial direction of the mounting cavity 51 until the fixing component 1 is installed in place. The limiting rib 514 is located in both the first limiting groove 211 and the second limiting groove 115, which constrains the fixing ring 21 and the tail cover 11 in the circumferential direction, preventing them from rotating relative to the housing 5, thereby avoiding the twisting of the cable 3 and affecting the stability of the cable 3 installation.

[0066] Optionally, the limiting ribs 514, the first limiting grooves 211 and the second limiting grooves 115 are respectively included in multiple sets. The multiple limiting ribs 514 are distributed at intervals along the circumference of the mounting cavity 51, the multiple first limiting grooves 211 are respectively arranged at intervals along the circumference of the fixing ring 21, and the multiple second limiting grooves 115 are respectively arranged at intervals along the circumference of the fixing component 1.

[0067] In embodiments of this utility model, such as Figure 1 and Figure 6 As shown, the cavity wall of the mounting cavity 51 is also provided with a second limiting step 512, and the charging gun 200 also includes a sealing body 4, which is located between the second limiting step 512 and the clamping member 2, and the sealing body 4 is sleeved on the cable 3.

[0068] In this embodiment, the sealing body 4 has a ring-shaped structure and is sleeved on the outer periphery of the cable 3. It is used to limit and fix the cable 3, improve the stability of the connection between the cable 3 and related components, and also has a certain sealing effect, improving the waterproof and dustproof performance of the mounting cavity 51. The second limiting step 512 is a stepped surface protruding outward from the cavity wall, which is used to provide a positioning reference for the assembly of the sealing body 4. When assembling the tail clamping device 100, the sealing body 4 is installed in place when it abuts against the second limiting step 512. When the assembly is completed, one end face of the sealing body 4 abuts against the stepped surface of the second limiting step 512, and the other end face of the sealing body 4 abuts against the fixing ring 21. In this way, the second limiting step 512 and the clamping member 2 together clamp and limit the sealing body 4 in the axial direction, preventing the sealing body 4 from displacing in the axial direction.

[0069] In actual implementation, the outer peripheral surface of the sealing body 4 is fitted with the cavity wall of the mounting cavity 51 to further ensure the stability of the position of the sealing body 4.

[0070] Optionally, the fixing component 1 is provided with a third locking protrusion 1131, and the cavity wall of the mounting cavity 51 is provided with a locking groove 513, wherein the third locking protrusion 1131 is detachably limited within the locking groove 513.

[0071] In this embodiment, the fixing component 1 and the housing 5 are detachably connected by the snap-fit ​​of the third snap protrusion 1131 and the snap-fit ​​groove 513, which facilitates subsequent disassembly and assembly. Furthermore, the outer surface of the housing 5 does not need to have holes for connecting with the fixing component 1, which is beneficial to the aesthetics of the charging gun 200.

[0072] Optionally, multiple third protrusions 1131 and slots 513 can be provided to ensure uniform force distribution and connection stability between the tail cap 11 and the housing 5.

[0073] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
