Description

Charging socket post

Technical Field

The utility model relates to an electric automobile fills the electric pile field, concretely relates to socket post charges.

Background

With the background of the development of intensive support policies, the country advocates green, clean and environment-friendly energy; the new energy electric automobile in China enters a rapid development track, a plurality of new energy electric automobile enterprises become the masterforce army with rapid industrial development, and the new energy electric automobile gradually becomes the mainstream of future development. No matter be pure electric vehicles or insert electric hybrid vehicle and all need external power supply to charge for its driving system, new energy automobile car end socket that charges on the existing market has some problems: when charging, the terminal plug power in rifle and the socket that charges is too big, is difficult for inserting or extract, long-time the use, influences the life of socket, for this reason, the urgent need solve current problem.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, an object of the present invention is to provide a charging socket post, which can reduce the insertion force between the charging gun and the socket.

In order to achieve the above object, the utility model relates to a socket post charges, including shell, circuit board and a plurality of terminal, it is a plurality of the terminal passes through circuit board fixed connection is in the shell, it is a plurality of the terminal with circuit board electric connection, a plurality of air discharge ducts have been seted up on the surface of terminal, and is a plurality of the air discharge duct is followed angle settings such as the axis of terminal, the axial length of terminal with set up on it the length of air discharge duct equals.

Further, the number of the air vent grooves on one terminal is 12.

Further, the terminal forms the exhaust groove by a glue-drawing treatment.

Furthermore, waterproof materials are coated on the outer surfaces of the shell and the terminal.

Furthermore, a plurality of mounting holes are formed in the shell.

Compared with the prior art, the utility model, its beneficial effect is:

the exhaust grooves are arranged in a plurality of positions, so that the purpose of reducing the insertion and extraction force is achieved (the friction force per unit area is unchanged, but the contact area is reduced, so that the total insertion and extraction force is reduced), the exhaust grooves are arranged at equal angles, so that the charging gun is uniformly stressed when being inserted and extracted, the actual use of an operator cannot be influenced due to excessive local stress, and the charging gun or the terminal can be damaged finally;

in conclusion, the device can achieve the purpose of reducing the insertion and extraction force of the charging gun and the socket.

Detailed Description

In order to explain the technical content, structural features, achieved objects and functions of the present invention in detail, the following embodiments are described in detail with reference to the accompanying drawings.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be taken as limiting the scope of the invention.

Referring to fig. 1 and fig. 2, the present invention provides an embodiment:

the utility model provides a to realize above-mentioned purpose, the utility model provides a socket post charges, including shell 1, circuit board 2 and a plurality of terminal 3, it is a plurality of terminal 3 passes through 2 fixed connection of circuit board are in the shell 1, it is a plurality of terminal 3 with 2 electric connection of circuit board, a plurality of air discharge duct 31 have been seted up on terminal 3's the surface, it is a plurality of air discharge duct 31 is followed angle settings such as the axis of terminal 3, the axial length of terminal 3 and setting are above that air discharge duct 31's length equals.

The air discharge duct 31 plays when the rifle that charges inserts on terminal 3, the gas in the terminal 3 can be followed air discharge duct 31 and flowed out, thereby reduce air discharge duct 31's insertion force, air discharge duct 31 is provided with a plurality ofly, play the purpose (the frictional force of unit area is unchangeable, but area of contact reduces, therefore total plug power reduces) of reducing plug power, air discharge duct 31 waits that the setting of angle plays the rifle that charges when the plug, the atress is even, can not appear because of local atress is too big, thereby influence operator's in-service use, the condition of damage rifle or terminal 3 finally can appear, the axial length of terminal 3 equals with the length of air discharge duct 31 that sets up on it plays the purpose of reducing plug power (the principle is the same with the principle that air discharge duct 31 is provided with a plurality ofly).

Further, the number of the vent grooves 31 in one of the terminals 3 is 12.

A large number of experiments of our company show that when 12 exhaust grooves 31 are arranged, the insertion and extraction force effect of the charging gun is optimal;

further, the terminal 3 forms the air vent groove 31 by a glue-drawing process.

Furthermore, waterproof materials are coated on the outer surfaces of the shell 1 and the terminal 3.

The waterproof material is arranged to prevent water from accumulating in the terminal 3 or the shell 1, so that the insertion and extraction force of the charging gun is increased;

further, a plurality of mounting holes 11 are formed in the housing 1.

The installation hole 11 is arranged to facilitate the installation of the shell 1 on the automobile, and the shell 1 is arranged on the side part of the automobile and is arranged obliquely downwards when being installed, so that the water in the shell 1 is prevented from flowing out due to other accidents.
