Description
Technical field
The utility model relates to a kind of connector, is specifically related to a kind of charge connector with life-span management function.
Background technology
Charge connector is for the construction of domestic charging station and the development important of electric automobile, and the critical piece of charge connector is contact, plays the important function of transmission current and signal.
Because contact has certain mechanical endurance, the plug number of times of electric connector has certain restriction, and present charging plug on the market generally relies on user's experience to judge useful life, has so just caused the unstable of connection reliability.Owing to adopt large current charge, in case the connection of connector is broken down, as easy as rolling off a logly be short-circuited, the phenomenon such as electric leakage, also might produce electric spark between the contact, these situations have consisted of great threat to the safety of equipment, vehicle and the person.
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of new solution.
The utility model content
The technical problems to be solved in the utility model is: be directed to the deficiencies in the prior art, a kind of charge connector with life-span management function is provided, this connector can show its plug number of times in real time, so that the operating position to this connector is made anticipation, give in time to scrap or change, realize the function of life-span management.
To achieve the above object of the invention, the technical scheme that the utility model adopts is: a kind of charge connector with life-span management function is provided, comprises housing and connector assembling section, it is characterized in that:
Described connector assembling section comprises that charging confirms terminal, earth terminal, switching device, PCB wiring board, is arranged on counting device, storage device and latch cicuit on the PCB wiring board;
Described housing is provided with for to the plug display unit that shows of number of times be used for the shift knob of control switch device;
Described charging confirms that a terminal part places in the housing, and a part is stretched out in housing; Described PCB wiring board, earth terminal and switching device are arranged in the housing; Described counting device confirms that with charging terminal is connected, and counting device is connected with storage device by latch cicuit simultaneously, and storage device is connected with display unit; Earth terminal and counting device are altogether.
Described counting device is digit counter.
Described storage device is nonvolatile memory.
Described display unit is LED display.
Described switching device is sensitive switch.
In sum, the charge connector with life-span management function that the utility model provides is by arranging digit counter at the PCB wiring board, digit counter confirms that with charging terminal is connected with nonvolatile memory respectively, nonvolatile memory is connected with LED display, digit counter is added up the plug number of times of this connector by the change in voltage of charging affirmation terminal, and pass to the user by LED display, the user just can know clearly the plug number of times of this connector, be about to arrive in limited time at the plug number of times, give in time to scrap or change, not only realize the function of life-span management, and avoided the electric leakage that causes in loosening or other situation connecting, the potential safety hazard that the phenomenons such as short circuit are brought human body and equipment, safety is saved worry more.
Description of drawings
The external structure schematic diagram of the charge connector with life-span management function that Fig. 1 provides for the utility model embodiment.
The internal structure schematic diagram of the charge connector with life-span management function that Fig. 2 provides for the utility model embodiment.
Wherein, 1, LED display; 2, shift knob; 3, housing; 4, earth terminal; 5, sensitive switch; 6, PCB wiring board; 7, nonvolatile memory; 8, latch cicuit; 9, digit counter; 10, terminal is confirmed in charging.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done and to be described in detail:
As shown in Figure 1, 2, the charge connector with life-span management function that the utility model provides comprises housing 3 and connector assembling section, and connector assembling section comprises charging affirmation terminal 10, earth terminal 4, sensitive switch 5, PCB wiring board 6; Charging confirms that terminal 10 parts place in the housing 3, and a part is stretched out in housing 3; Earth terminal 4, sensitive switch 5 and PCB wiring board 6 are arranged in the housing 3; PCB wiring board 6 is provided with digit counter 9, nonvolatile memory 7 and latch cicuit 8; Housing 3 is provided with the shift knob 2 of LED display 1 and control sensitive switch 5.
The specific works process of the connector that the utility model embodiment provides is as follows: press shift knob 2, open sensitive switch 5, this connector is inserted socket, charging is confirmed will obtain a voltage between terminal 10 and the earth terminal 4, and the circuit on the driving PCB wiring board 6 resets digit counter 9; When being inserted into, decontrol sensitive switch 5, charging confirms that the voltage between terminal 10 and the earth terminal 4 changes, digit counter 9 receives count signal, counting adds 1, and data are sent to nonvolatile memory 7 finishes data storages, and then latch cicuit 8 is with it locking; After charging is finished, press sensitive switch 5, pull up connector, because latch cicuit 8 locking, data can not change because of the sudden change of voltage or power down.In whole galvanization, LED display 1 shows the current plug number of times of storage in the nonvolatile memory 7, and the user just can know clearly the plug number of times of this connector, is about to arrive in limited time at the plug number of times, give in time to scrap or change, thus the function of realization life-span management.
Connector of the present utility model can be widely used in electric motor car, electric automobile etc. to be needed in the device of charging, easy to use, safety.
In addition, counting device of the present utility model also can adopt alternate manner to realize, such as the mode that can adopt single-chip microcomputer or single-chip microcomputer to cooperate with digit counter (simulative counter), finishes more complexity by programming and counts more accurately action; Also can design special embedded system and realize these functions.The form of various circuit also can be Protean on the pcb board in addition, and the variable of counting institute foundation also can be that different, such conversion all drops within protection scope of the present invention.
The utility model is not limited to above-mentioned example, in claims limited range of the present utility model, and various distortion that those skilled in the art can make without creative work or revise the protection that all is subjected to this patent.
