Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, specifically to a cable protection fixing structure. Background Technology

[0002] With the popularization of new energy vehicles, charging piles have become an indispensable facility. At the connection points between the charging pile cabinet and the charging gun cable, the connection ports need to be dustproof, waterproof, and anti-loosening. For example, application number CN201920158323.1 discloses a flange-type waterproof connector for charging piles, including a connector body and a locking nut. The connector body is a pipe fitting with an external threaded interface at one end, and a flange at the other end. A sealing ring groove is provided on the end face of the flange, and an O-ring is embedded in the sealing ring groove. The locking nut is connected to the external threaded interface of the connector body via threads. The inner wall of the locking nut has a stepped surface, and a circular washer and an annular seal are coaxially arranged inside the locking nut. The circular washer and the annular seal are located between the stepped surface and the end face of the external threaded interface of the connector body. Four connection holes are provided on the flange, and bolts are installed in the connection holes. The bolts are connected to a welded waterproof nut inside the charging pile cabinet.

[0003] The connectors in the aforementioned documents serve a fixing and waterproofing function, but do not provide cable protection. Therefore, excessive bending of the charging gun cable during on-site use can cause the cable sheath to break. Utility Model Content

[0004] To address the technical problem that existing connectors cannot simultaneously provide both waterproofing and cable protection, and that excessive bending of cables can easily lead to damage to the cable sheath, this invention provides a cable protection and fixing structure that solves the aforementioned technical problems.

[0005] The technical solution adopted in this utility model is as follows:

[0006] This utility model provides a cable protection and fixing structure, including:

[0007] A sleeve includes a tubular portion, one end of which has a fixing portion extending radially, and the other end of which has an anti-bending portion extending axially, and the inner surface of the sleeve has at least two sealing flanges extending therefrom.

[0008] A fixing component is sleeved on the outside of the tubular part and pressed against the fixing part, and a first fastener passes through the fixing component and the fixing part for fixing.

[0009] According to one embodiment of the present invention, the fixing component includes a fixing flange and a locking component. The first side of the fixing flange is pressed against the fixing part, and the first fastener passes through the fixing flange and the fixing part for fixing. The second side of the fixing flange extends with a protrusion, and the locking component is fixed to the protrusion and locks the tubular part.

[0010] According to one embodiment of the present invention, the locking assembly includes at least two locking plates arranged circumferentially, with a protrusion provided between two adjacent locking plates, and a second fastener passing through the locking plates and the protrusion for fixation.

[0011] According to one embodiment of the present invention, sealing flanges are formed on the inner surfaces of both ends of the sleeve.

[0012] According to one embodiment of the present invention, the thickness of the tubular portion is greater than the thickness of the anti-bending portion.

[0013] According to one embodiment of the present invention, the outer surface of the tubular portion and the outer surface of the anti-bending portion are transitioned by a tapered surface.

[0014] According to one embodiment of the present invention, the thickness of the anti-bending part varies regularly.

[0015] According to one embodiment of the present invention, the outer surface of the anti-bending part is provided with grooves, which are arranged regularly along the circumferential and axial directions, and two adjacent grooves in the axial direction are staggered in the circumferential direction.

[0016] According to one embodiment of the present invention, a closed sealing protrusion is formed on the end face of the fixing part away from the fixing component.

[0017] According to one embodiment of the present invention, the sleeve is made of rubber.

[0018] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0019] 1. The cable protection and fixing structure of this utility model includes a sleeve comprising a tubular part, a fixing part, and an anti-bending part. The sleeve is fitted over the outside of the cable. The fixing part is used for fixing, and the anti-bending part can interfere with and prevent excessive bending when the cable is bent, thereby protecting the cable. The sealing flange formed on the inner surface of the sleeve can provide a sealing and waterproof function. That is, the cable protection and fixing structure of this utility model can simultaneously provide sealing, waterproofing, and anti-bending functions, avoiding the technical problem of cable sheath damage when the cable is bent excessively. The sleeve is an integral structure, reducing the number of parts and facilitating assembly.

[0020] 2. The cable protection and fixing structure of this utility model includes a fixing flange and a locking component. The fixing flange is pressed against the fixing part to fix it. The locking component is fixed to the protrusion of the fixing flange and locks the tubular part, which can help enhance the strength of the tubular part and prevent the cable from being excessively bent when the cable is pulled and bent repeatedly. The cooperation between the fixing flange and the locking component can also prevent the fixing part from coming off under the influence of the cable.

[0021] 3. In the cable protection and fixing structure of this utility model, the thickness of the tubular part is greater than that of the anti-bending part. The tubular part can work with the fixing components to stabilize and fix the cable. The thickness of the anti-bending part is smaller, allowing the cable to bend within a certain range. The anti-bending part achieves a regular thickness change by setting grooves, which can effectively protect the cable and prevent excessive bending.

[0022] 4. In the cable protection and fixing structure of this utility model, a closed sealing protrusion is formed on the end face of the fixing part. When the end face is pressed against the wall of the fixed box, the sealing protrusion can form a sealing fit with the box wall, thereby playing a role in sealing and waterproofing.
