Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically to a modular high-voltage connector. Background Art

[0002] At present, the housing of high-voltage connectors such as sockets is provided with mounting holes for bolts to pass through. When in use, the socket is installed at the interface of the automobile equipment by bolts. In reality, due to the restrictions of different models and equipment sizes of users, different mounting hole distances need to be set.

[0003] In this context, when faced with different installation hole spacings, sockets of different specifications need to be produced to cope with them. However, due to the high overall injection molding degree of conventional sockets, many structures other than the terminals, such as the inner core, are integrally injection molded on the shell. When the installation hole spacing on the equipment end is adjusted beyond the established production data due to temporary adjustments, it is necessary to re-produce the shell of the socket of a new specification to adapt to the new installation hole spacing. This results in the shell of the socket of the original specification being discarded and cannot be disassembled and reused, ultimately resulting in a waste of resources.

[0004] Therefore, it is economically promising to develop modular connectors to increase the commonality of parts in products with different hole pitch specifications. Utility Model Content
