Description

Technical Field

[0001] The utility model belongs to the technical field of charging piles, and particularly relates to a high-stability waterproof cable connection fixator. Background Art

[0002] At present, the common cable connection fixators on the market can basically meet the charging needs of most new energy vehicles, and their long-term use safety is the key concern. During the charging process of the charging gun, a large amount of heat is generated at both the charging terminal and the joint between the cable and the external power supply. In order to cool the terminal in time, liquid-cooled terminals have emerged. Conventional liquid-cooled terminals usually have a liquid-cooled pipe added outside the cable. The gap between the liquid-cooled pipe and the cable forms a water inlet and outlet water path, which is the same as that inside the terminal respectively, forming a circulating cooling water path for cooling. To ensure the effective continuous flow of the coolant and thus ensure the cooling effect, in the existing conventional liquid-cooled charging piles, the liquid-cooled pipe and other charging cables are easily squeezed during use, resulting in poor circulation of the liquid-cooled pipe, causing a decrease in the heat dissipation effect, and further reducing the service life of the charging pile. Summary of the Utility Model

[0003] To solve the problems mentioned in the above background art, a high-stability waterproof cable connection fixator is proposed. By adding a positioning clip, it can prevent the cable from loosening and at the same time prevent the cable from squeezing the liquid-cooled pipe, improving the stability of the product.

[0004] The technical solution of the utility model: A high-stability waterproof cable connection fixator includes a housing and a cable assembly inside the housing. The cable assembly penetrates through the housing. The cable assembly includes a liquid-cooled pipe and a cable. There are multiple limiting clip assemblies on the cable. The limiting clip assembly includes a first limiting clip and a second limiting clip. There are multiple grooves between the first limiting clip and the second limiting clip for placing the cable. A sealing ring is provided between the cable assembly and the housing. The bottom end of the housing is provided with a base, and the base is provided with multiple gears for pressing the sealing ring. Multiple limiting ribs are provided on the housing near the sealing ring for abutting and positioning the sealing ring.

[0005] Preferably, the first limiting clip and the second limiting clip are connected by bolts, and the bolts are used to adjust the tightness to fix the cable.

[0006] Preferably, the housing is provided with a limiting groove, and the limiting clip assembly is limited and fixed in the limiting groove.

[0007] Preferably, a sealing ring is provided at the top end of the housing for sealing when the housing is installed and connected to the charging pile.

[0010] Compared with the prior art, the present utility model provides a highly stable waterproof cable connection fixer, which has at least one of the following beneficial effects:

[0011] 1. The cable is fixed and limited by the limit clip, which can prevent it from loosening and avoid squeezing the liquid cooling pipe at the same time, improving the stability of the product.

[0012] 2. By providing a base crimping sealing ring at the bottom end of the outer shell to make it deform and fit more tightly, the sealing performance is increased. A sealing ring is installed at the connection charging pile at the top end of the outer shell to improve its sealing performance, thereby ensuring the waterproofness of the product.
