Description

Technical Field

[0001] The invention relates to the field of connectors, and in particular to a two-core charging connector. Background Art

[0002] Batteries, storage batteries and other energy storage units are used in electric equipment such as electric bicycles and electric forklifts. At present, the widely used charging connectors for these energy storage units are two-core connectors, which can only be used for charging. There are no interfaces for power management, network transmission and other functions. The performance is single, which is not conducive to the functional expansion of charging equipment, and there is no waterproof function. With the implementation of a number of national standards such as GB / T42236.1-2022 "Electric Bicycle Centralized Charging Facilities Part 1: Technical Specifications", clear requirements are put forward for the power management and network transmission of charging facilities. Therefore, the current charging connectors cannot fully meet the requirements; such as Figure 1 As shown, the large number of two-core connectors currently in use cannot be scrapped immediately, otherwise it will cause huge waste. Therefore, a charging connector that is compatible with the current two-core charging connector and meets national standards is needed. Summary of the invention

DETAILED DESCRIPTION

[0014] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0015] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0016] like Figure 1The two-core charging connector of the prior art is shown, and its size is 3×8 cm as specified by the standard. The plug and the socket can be coupled with each other. It is a charging interface that has been implemented on a large scale and cannot be replaced in large quantities in a short period of time.

[0017] like Figure 2 As shown, the socket of the connector of this embodiment is provided with a rectangular charging terminal 2, and the charging terminal 2 has two charging interfaces. A group of control terminals 3 are provided on the side of the charging terminal 2, and the control terminal has two control interfaces. A docking shell 1 is provided on the socket, and the charging terminal 2 and the control terminal 3 are provided in the docking shell 1.
