Description

Technical Field

[0001] This utility model relates to the field of charging gun technology, and in particular to a fixing clamping device for charging gun cables. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the performance and safety of charging guns, as a key interface for vehicle charging, have attracted much attention. The cable clamping device for the charging gun is a crucial component for ensuring a stable cable connection and a safe and reliable charging process; however, there are currently many shortcomings in this area.

[0003] Existing charging gun cable clamping devices have limited ability to limit and protect the cable. During frequent plugging and unplugging of charging guns and the dragging and bending of cables, the cables are prone to excessive stretching and twisting due to the lack of effective restraint, resulting in damage to the internal wires. This can lead to charging interruptions, leakage, and other safety hazards, seriously affecting charging safety and user experience.

[0004] In terms of structural design, some components are not well-designed. The cable fixing module lacks a proper stepped layout with insufficient tightness and stability. Under external impact, relative displacement can easily occur between components, failing to provide reliable support and fixation for the cable. Furthermore, the device's sealing performance is poor, allowing moisture and dust to easily penetrate in humid, dusty, or other harsh environments, corroding cables and electrical components and reducing the device's lifespan. Utility Model Content

[0005] To address some of the problems existing in the prior art, this utility model provides a fixing and clamping device for charging gun cables. This utility model enhances the overall structural stability and sealing by integrally molding the cable protective shell and the charging gun shell. The cable limiting module uses arc-shaped limiting blocks, multi-layer arc-shaped plates, limiting protrusions, positioning blocks, and other structures to accurately limit the cable. A sealing surface and positioning structure are provided between the cable fixing module and the limiting component, and multiple fixing ring plates are provided inside to effectively fix the cable and ensure the stable use of the charging gun cable.

[0006] To achieve the above objectives, this utility model provides a fixing clamping device for charging gun cables, including a fixing clamping device body, the fixing clamping device body including a cable fixing component, the cable fixing component being connected to a cable limiting component, the cable limiting component including a cable protective shell, the cable fixing component including a cable fixing module, the cable fixing module and the cable protective shell being arranged in a stepped manner, and the cable protective shell being integrally formed with the charging gun shell.

[0007] As a further improvement of this utility model, in order to improve the stability and reliability of the limit and ensure that the cable does not shake or shift during charging, the cable limit assembly is provided with a limit module for limiting the cable in addition to the cable protective shell. The limit module consists of two arc-shaped limit blocks. The upper and lower ends of the limit blocks are fixedly connected by bolts. The inner side of the limit block is provided with multiple layers of arc plates, and the four outer corners of the arc plates are provided with positioning arc surfaces for bolt installation.

[0008] As a further improvement of this utility model, in order to limit the cable from multiple directions, further enhance the constraint ability on the cable, prevent the cable from shifting in the radial and axial directions, improve the stability of the cable fixation, and ensure the stability and safety of the charging process, multiple sets of limiting protrusions are respectively provided on the inner and outer sides of the limiting block. The limiting protrusions are respectively located at the upper and lower ends of the inner and outer arc plates, and the limiting protrusions are arranged opposite to each other.

[0009] As a further improvement of this utility model, in order to make it easier for the cable to enter the limiting module and to better hold the cable after fixing, prevent it from loosening, and improve installation efficiency and fixing effect, multiple sets of positioning blocks are provided in the middle of the limiting block. The positioning blocks are located at the upper, middle and lower ends of the middle arc plate, respectively. The positioning blocks at the upper and lower ends are set at an angle and are set opposite to each other.

[0010] As a further improvement of this utility model, in order to enable quick and accurate positioning, ensure the installation accuracy of the cable fixing module and the cable limiting component, and make the two fit tightly to further enhance the sealing effect, a sealing surface is provided between the cable fixing module and the cable limiting component. Positioning holes are provided at the four outer corners of the sealing surface, and positioning grooves are provided at the four corners of the cable fixing module in conjunction with the positioning holes.

[0011] As a further improvement of this utility model, in order to increase the contact layers and friction with the cable, and to more firmly fix the cable, preventing the cable from loosening or falling off due to pulling, vibration or other reasons during charging, and at the same time dispersing the stress on the cable and reducing damage to the cable, the cable fixing module is also provided with multiple layers of fixing ring plates inside.

[0012] When this utility model is in operation, the charging gun cable is carefully passed through the cable protection shell in the cable limiting assembly; the cable protection shell provides initial protection for the cable, preventing the cable from being scratched or bumped by external objects during subsequent operation and use.

[0013] The limiting module, consisting of two arc-shaped limiting blocks, is placed over the cable that has passed through the cable protection shell. The upper and lower ends of the limiting blocks are fixedly connected with bolts. At this time, the multi-layer arc-shaped plates on the inner side of the limiting blocks are tightly fitted to the cable. The positioning arc surfaces at the four corners of the outer side of the arc plates provide precise positioning for bolt installation, ensuring that the bolts are firmly installed and further stabilizing the cable position. At the same time, multiple sets of limiting protrusions on the inner and outer sides of the limiting blocks are located at the upper and lower middle ends of the inner and outer arc-shaped plates, respectively, to limit the cable in multiple directions and prevent the cable from moving in the horizontal direction. In addition, multiple sets of positioning blocks in the middle of the limiting blocks are located at the upper, middle, and lower ends of the middle arc plate. The upper and lower positioning blocks are inclined and opposite to each other, which can effectively prevent the cable from moving in the vertical direction.

[0014] The cable, which has been secured by the limiting module, continues to pass through the multi-layered fixing ring plates inside the cable fixing module. These fixing ring plates fix and support the cable from different positions, enhancing the stability of the cable and reducing the shaking of the cable during use.

[0015] A sealing surface is used to seal between the cable fixing module and the cable limiting component, effectively preventing dust, moisture, and other contaminants from entering the device and avoiding damage to the cable and the device. The positioning holes at the four corners of the outer side of the sealing surface cooperate with the positioning grooves at the four corners of the cable fixing module to ensure that the entire device is installed accurately and securely.

[0016] The beneficial effects of this utility model are as follows:

[0017] Secure and stable, ensuring charging safety: The cable fixing module and cable limiting component are arranged in a stepped configuration, with the cable fixing module containing multiple layers of fixing ring plates. The limiting module uses multiple layers of arc-shaped plates, limiting protrusions, and positioning blocks to provide omnidirectional cable restraint from multiple directions, including horizontal and vertical. This multi-layered and multi-directional fixing method effectively prevents the charging gun cable from shaking or shifting during use, avoiding safety hazards such as poor contact and short circuits caused by loose cables, ensuring a stable and reliable charging process, and greatly improving charging safety.

[0018] Excellent protection and extended service life: The cable protection shell is integrally molded with the charging gun shell, providing a solid outer layer of protection for the cable and effectively resisting collisions and scratches from external objects. Meanwhile, the sealing surface design between the cable fixing module and the cable limiting component prevents dust and moisture from entering the device, preventing aging and corrosion of the cable due to moisture and dust accumulation. This extends the service life of the cable and the entire fixing and clamping device, reducing operating costs.

[0019] Precise positioning facilitates installation and maintenance: The positioning arc surfaces at the four corners of the curved plate, the positioning holes at the four corners of the sealing surface, and the positioning grooves at the four corners of the cable fixing module provide precise positioning for the installation of each component of the device. This not only makes the installation process simpler and faster, improving installation efficiency, but also facilitates subsequent maintenance and repair work. Attached Figure Description
