Embodiment 1
[0026] as attached Figures 1 to 2 , and the attached Figure 4 As shown, a new type of electric vehicle connector plug with convertible pins, which includes:
[0027] The power supply plug 1 is provided with a power supply pin 11 .
[0028] The power supply pin 11 is connected with the power supply cable 3 .
[0029] The signal pin 13 is arranged on the power supply plug 1 ; the protruding length of the signal pin 13 on the power supply plug 1 is smaller than the protruding length of the power supply pin 11 on the power supply plug 1 .
[0030] The conversion plug 2 is detachably connected to the power supply plug 1. The conversion plug 2 is provided with a jack 21 connected to the power supply pin 11, and a connecting pin 22 electrically connected to the jack 21. The connecting pin 22 is used for connecting with the power supply pin 11. The sockets match.
[0031] The current detection part 4 is electrically connected with the conversion plug 2. The current detection par...
Embodiment 2
[0035] On the basis of embodiment one, as attached image 3 As shown, the jack 21 is divided into a power supply jack 24 and a signal jack 25, wherein, when the power supply plug 1 and the conversion plug 2 are connected, the power supply jack 24 is matched with the power supply pin 11, and the signal jack 25 is connected to the signal jack 25. Pin 13 is connected.
Embodiment 3
[0037] On the basis of embodiment two, as attached figure 1 with 2 , and the attached Figure 5 As shown, the two sides of the conversion plug 2 are provided with elastic fasteners 23, and the two sides of the power supply plug 1 are provided with buckles 12 that match the elastic fasteners 23; when the power supply plug 1 and the conversion plug 2 are connected, the elastic fasteners 23 Can be fastened in the buckle 12.
[0038] The conversion plug 2 also includes a spring 26, which abuts against the elastic fastener 23, and the spring 26 drives the buckled position 12 to switch from the locked state to the disassembled state.
[0039] The elastic fastener 23 is fixed in the middle of the conversion plug 2, and the conversion plug 2 is provided with an operation hole for operating the buckle 12.

Abstract
The invention relates to the field of electric vehicle connectors, and in particular relates to a novel electric vehicle connector plug with a convertible contact pin. The electric vehicle connector plug comprises a power supply plug and a changeover plug, wherein the power supply plug is provided with a power supply contact pin, the power supply contact pin is connected with a power supply cable; the changeover plug is detachably connected with the power supply plug, and the changeover plug is provided with a jack connected with the power supply contact pin, and a connecting contact pin electrically connected with the jack, and the connecting contact pin is used for inserting in the plug. The electric vehicle connector plug further comprises a current detector electrically connected with the changeover plug, a temperature detector electrically connected with the changeover plug, wherein the the current detector is a current detection resistor and can be used for detecting the current system of the access current; and the temperature detector is a thermosensitive resistor and can be used for detecting the temperature of the changeover plug. The electric vehicle connector plug has the beneficial effects that the changeover plug is added to detachably connect with the power supply plug, a user can select the appropriate changeover plug according to the local power utilization system, thereby improving the applicability of the charging connector.
Description
technical field [0001] The invention relates to the field of electric vehicle connectors, in particular to a novel electric vehicle connector plug with convertible pins. Background technique [0002] At present, with the continuous popularization of electric and hybrid vehicles, the charging of these vehicles and related issues have not only become a technical problem, but also initially formed a considerable market. At present, all kinds of charging equipment are developing vigorously, and the public charging facilities led by the government and large enterprises are constantly expanding, which has become a hot spot for current investment, while the development of household charging methods is relatively slow. One of the factors restricting household charging methods is that different countries and regions currently use different current standards, making it difficult for existing charging facilities to be used universally, making it difficult for production to produce econ...
