Description
Technical field
The present invention relates to charging connector for electric automobile field, be specifically related to a kind of charging connector for electric automobile be easy to and safeguard.
Background technology
In electric automobile field, charge connector is the vitals in charging system.
During routine use, during charging electric vehicle, charge connector often needs frequent plug, the parts such as contact pin therein, jack (terminal) the most easily occur loss under the effect of the internal and external factors such as big electric current, high temperature, other corrosive deposits, thus are prone to further result in whole adapter and break down.Once break down, owing to existing charge connector is all 1 fixing overall structure, the particularly parts such as contact pin, jack (terminal) are all that complexity links together with other structures, to be replaced, technical difficulty is big, and cost is high, can only scrap whole adapter so the most whole, this has resulted in great waste, substantially increases the cost of user.
Summary of the invention
For above-mentioned technical problem: the present invention provides a kind of charging connector for electric automobile be easy to and safeguard, it passes through structure optimization, when easily damaging occur in consumption parts for contact pin, jack (terminal) etc., can be replaced convenient, at low cost safeguarding, reduce use cost, improve the ruggedness of whole charging connector for electric automobile.
For solving above-mentioned technical problem, the present invention specifically provides a kind of technical scheme: a kind of charging connector for electric automobile being easy to safeguard, including body part and front end component.
Body part can match slotting with front end component.
Body part includes body housing and female terminal；Front end component includes front end shell and male plug pin.
Body housing and front end shell are the tubular structure of before and after's opening.
Female terminal is arranged on inside body housing；The front end of female terminal is exposed at the front opening of body housing, and rear end is connected with cable.The rear end of female terminal can be to crimp with the connected mode of concrete cable.
Male plug pin is arranged on inside front end shell；The rear end of male plug pin is exposed at the open rearward end of front end shell.According to the regulation of GB20234, this adapter arranges 9, male plug pin.
When body part and front end component match slotting, the rear end of the front end of female terminal and male plug pin matches and inserts and admittance.
In the technical scheme optimized further, body housing includes fixing hook, and front end shell includes that cover edge, fixing hook are arranged on the outside at body housing front opening, and cover is along the periphery being arranged on front end shell.When body part and front end component match slotting, fixing hook buckles cover edge, covers at the front opening of enclosed body shell.
In the technical scheme optimized further, aforesaid female terminal front end and male plug pin rear end match slotting in specifically to join slotting mode can be that screw thread screws or spring formula plugs together.Slotting mode that what screw thread screwed join refers to that the front end of female terminal and the rear end of male plug pin are both provided with the screw thread that can mutually screw.When matching slotting, both rely on screw thread to screw and can interfix and admittance；What spring formula plugged together join slotting mode refers to that the front end of female terminal is both provided with reed, and when matching slotting, whippy reed can be clamped on the periphery of the rear end of male plug pin, so that both interfix and admittance.
After have employed technique scheme, the invention has the beneficial effects as follows:
Relative to disclosed technical scheme, this charging connector for electric automobile passes through Mechanism Optimization, charger total is decomposed into body part and front end component 2 major part, wherein front end component is mainly male plug pin etc. and easily consumes structure, it is damaged once its front end component, occurred fault can be overcome by changing front end component, avoid owing to fraction fault just scraps whole charge connector, reduce the working service cost of adapter, improve the ruggedness of whole charging connector for electric automobile.
Front end component can be fabricated to canonical form simultaneously, carry out selling or dispensing with the form of spare part.Having had front end component, the user of charge connector can carry out self-help replacing easily, thus eliminates the maintenance cost of specialty.
Outside at the front opening of body housing is provided with fixing hook, the periphery of front end shell is provided with cover edge, when body part matches slotting with front end component, fixing hook can buckle cover edge, this 1 structure plays the effect of fixing retaining, and when can prevent joining slotting, body part is surprisingly separated with front end component；And when body part matches slotting with front end component, cover at the front opening of enclosed body shell, sealing, the effect of protection internal structure can be further functioned as.
It can be that screw thread screws or spring formula such as plugs together at 2 kinds of modes, use demand when can meet difference that slotting mode is specifically joined in female terminal front end and male plug pin rear end, has widened the adaptive surface of product.
