Description

Technical Field

[0001] This utility model relates to a charging dock cable module and a charging dock including the charging dock cable module. Background Technology

[0002] In existing technology, DC charging docks typically include a housing, an end cap, two power terminals, two power cables, a protective ground terminal (usually called a PE terminal), and a grounding cable. The two power terminals, the protective ground terminal, and multiple signal terminals are inserted into the housing. The end cap is mounted on the rear end of the housing. The two power cables pass through the end cap and are electrically connected to the two power terminals respectively. The grounding cable passes through the end cap and is electrically connected to the protective ground terminal. The relatively large size of the grounding cable not only increases the size of the charging dock but also increases cost.

[0003] Furthermore, in existing technology, a cable through-hole is formed on the end cover of the charging dock, through which the power cable extends into the housing of the charging dock. However, the direction of the cable through-hole is fixed and cannot be adjusted as needed. This results in the power cable exiting from the end cover of the charging dock also being in a fixed direction, preventing necessary adjustments based on actual needs and limiting the range of applications of the charging dock.

[0004] Furthermore, in existing technology, a mounting hole is formed on the end cap of the charging dock to allow a threaded connector to enter. This threaded connector passes through the connection end of the power cable and is threadedly connected to the power terminal to electrically connect the power cable to the power terminal. To seal the mounting hole on the end cap, a sealing plug needs to be placed in the mounting hole. To position and retain this sealing plug, a sealing plug positioning cap also needs to be installed on the end cap of the charging dock, which increases costs.

[0005] Furthermore, in existing technology, one end of the adapter bus is directly connected to one end of the protective grounding terminal via bolts. Because the protective grounding terminal is positioned between the two power terminals, the adapter bus is located between two charging dock cable modules that are respectively connected to the two power terminals. The adapter bus is confined between the two charging dock cable modules and cannot rotate, as this would interfere with the charging dock cable modules. This makes the configuration direction of the adapter bus fixed and cannot be rotated or changed as needed. Utility Model Content
