Description

Plug connector switching device

Technical field

The present invention relates to a kind of plug connector, more particularly to a kind of plug connector switching device.

Background technology

Facility is used in the polynary life there is provided consumer of the function of electronic product now, for example：Drive recorder or satellite The running gears such as navigation, or camera, mobile communication device（Mobile phone）Deng being available for operating at any time, learn the benefits such as message.

General electronic products must power to maintain exercisable time length with power supply itself, when electronic product electric power When not enough, it can be charged using transmission line grafting civil power.

So that Automobile fills as an example, two terminal adapters of transmission line are that car fills device, USB connector respectively, and device insertion is filled with car In cigarette lighter socket, and USB connector connection electronic product, allow electronic product to be charged.If however, beverage sprinkles USB companies When connecing device, connection "on" position is in because other end car fills device, the parts such as terminal and circuit board in USB connector is caused short Road.

Therefore the problem of how solving conventional construction, is the problem of related dealer must think deeply place.

The content of the invention

In view of the above problems, the plug connector that the present invention provides a kind of changeable energization, power-off is used, uses solution Certainly known connector construction under general state to be powered, when causing beverage etc. to sprinkle internal terminal, the problem of causing short circuit.

The present invention provides a kind of plug connector switching device, including header body, circuit board and changeover module, plug The side of body includes the grafting space in docking housing and docking housing, and circuit board is located at header body and connects complex conduction Piece, changeover module connection circuit board, changeover module includes drive link, contact chip and elastic component, and drive link runs through circuit board, transmission One end of bar is located at grafting space, the adjacent complex conduction piece of contact chip and the other end for connecting drive link, elastic component socket transmission Bar, when housing is docked in electric connector for socket grafting, one end of drive link is compressed and interlocked another end movement of drive link, The contact chip connection complex conduction piece of the other end of drive link.

The present invention forms unpowered state not in contact with conducting strip by the contact chip of changeover module, is electrically connected in non-grafting socket When connecing device, beverage can be avoided to spill plug connector, cause short circuit phenomenon.Also, when electric connector for socket grafting docking During housing, the contact chip connection complex conduction piece of the other end of drive link can be compressed and interlocked by one end of drive link, Carry out the effect of energization transmission.In addition, the through hole of circuit board inserts stop collar, and transmission is socketed in using stop collar Bar, by close isolation aqueous vapor by through hole into there is provided waterproof effect.
