TECHNICAL FIELD

[0001] The application relates to the technical field of charging, in particular to a pogo pin charging assembly, a charging base and a charging device. BACKGROUND

[0002] The EFT performance refers to the anti-interference ability of an electronic device when the electronic device is subjected to electrical fast transient (EFT) interference. The EFT is a group of high-frequency and low-energy pulses, which is usually caused by the switching action of an inductive load (such as a relay, a contactor, a heavy motor, etc.), and can generate narrow and high-frequency transient pulses in a power distribution system. These transient pulses can interfere with the normal operation of the electronic device, and can cause data transmission errors or damage to the device. The current charging base on the market often has the problem of substandard EFT performance.

[0003] At present, the charging base on the market is mostly connected through a double-head pogo pin and a small plate elastic contact, and then the small plate is connected to the main board through a cable and a connector. This method has a large number of conversion times, and each conversion generates impedance, resulting in substandard EFT performance and slow charging speed. CONTENT OF THE INVENTION

Obviously, the drawings in the following description are only some examples or embodiments of the present application, and for those skilled in the art, the present application can also be applied to other similar scenarios without creative labor. Unless it is obvious from the language environment or otherwise stated, the same reference signs in the drawings represent the same structure or operation.

[0041] As used in this application and the appended claims, the articles "a," "an," and "the" are not limited to refer to only one of the identifiable items but are understood to be used in the inclusive sense of one or more of the identifiable items, unless otherwise indicated. Generally, the terms "including," "includes," "comprising," "comprises," and the like, are not limited to the identifiable items recited but are understood to mean that one or more of the identifiable items are included, but not necessarily every one of the identifiable items.

[0042] In the description of the present application, it is to be understood that the orientation or positional words such as "front", "back", "upper", "lower", "left", "right", "transverse", "vertical", "horizontal", and "top", "bottom" and the like indicated orientation or positional relationship are generally based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and in the absence of contrary description, these orientation words do not indicate and imply that the devices or elements referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the scope of protection of the present application; the orientation words "inner", "outer" refer to the inner and outer relative to the contour of the components themselves.
