Description
Technical field
The present invention relates to electric connector field, particularly relate to a kind of electric connector housing assembly and electric coupler component.
Background technology
Electric coupler component comprises plug and socket.Nowadays, it has become indispensable parts in various electric loop, in actual application, in order to ensure the reliable connection of electric loop, generally all be provided with corresponding retaining mechanism between the plug and socket of electric coupler component, such as coupling nut retaining mechanism, ball lock mechanism etc. are all retaining mechanisms comparatively common in electric connector field.
The reliability of above-mentioned retaining mechanism all obtains good checking in product practical application.But, in the occasion that some are special, the external application signal connector of such as electric bicycle, it not only requires can lock reliably between the plug of electric coupler component and socket, and require its have enough little volume, can fast insert-pull and there is lower cost etc.And above-mentioned retaining mechanism is all exist as the optional feature on the housing of plug and/or socket, such as coupling nut retaining mechanism needs assembly connection nut on plug casing, ball lock mechanism not only needs to assemble locking cap on plug casing, and needs on Socket casing, arrange corresponding steel ball.By contrast, the structure of coupling nut retaining mechanism is comparatively simple, but but there is the problem of operation inconvenience (all needing to be rotationally connected nut when locking and unblock), although ball lock mechanism can realize the direct inserting and drawing between plug and socket, but its complex structure, will certainly increase the cost of electric coupler component, the more important thing is, above-mentioned retaining mechanism as appurtenances all certainly will can increase the volume of electric coupler component entirety, makes it cannot be applied to the occasion in little space.
Summary of the invention
The object of the present invention is to provide a kind of electric connector housing assembly carrying retaining mechanism, to reduce the volume of electric coupler component, reduce the space needed for electric coupler component is installed.
Meanwhile, the present invention also aims to provide the electric coupler component using above-mentioned housing unit.
In order to solve the problem, electric connector housing assembly is by the following technical solutions: electric connector housing assembly, comprising is separately plug casing and the Socket casing of inserted terminal with front end, one in plug casing and Socket casing is public housing, another is parent shell, the front end of parent shell is integrally formed with two or more claw, each claw all extends to the front of parent shell and forms elastic cantilever structure, each claw surrounds a breathing mouth together, and the outer peripheral face of public housing is provided with the draw-in groove corresponding with claw.
The outer peripheral face of public housing is provided with the positioning key for coordinating with parent shell key, and parent shell is provided with the keyway corresponding with described positioning key.
Described keyway is by the gap-forming between adjacent two claws.
The front end of public housing has the section of being sealed and matched, and sealing coordinates section to be provided with seal for being sealed and matched with the inner peripheral surface of parent shell.
Electric coupler component is by the following technical solutions: electric coupler component, comprising is separately the plug and socket of inserted terminal with front end, the Plug contact that plug comprises plug casing and is fixedly assemblied in plug casing, the socket contact that socket comprises Socket casing and is fixedly assemblied in Socket casing, one in plug casing and Socket casing is public housing, another is parent shell, the front end of parent shell is integrally formed with two or more claw, each claw all extends to the front of parent shell and forms elastic cantilever structure, each claw surrounds a breathing mouth together, the outer peripheral face of public housing is provided with the draw-in groove corresponding with claw.
The outer peripheral face of public housing is provided with the positioning key for coordinating with parent shell key, and parent shell is provided with the keyway corresponding with described positioning key.
Described keyway is by the gap-forming between adjacent two claws.
Respectively be provided with corresponding assembly wall in plug casing and Socket casing, Plug contact and socket contact are arranged on corresponding assembly wall respectively.
Described plug casing and Socket casing rear end is separately equipped with casting glue, and Plug contact and socket contact are fixed respectively by corresponding casting glue.
The front end of public housing has the section of being sealed and matched, and sealing coordinates section to be provided with seal for being sealed and matched with the inner peripheral surface of parent shell.
Front end due to the parent shell of this electric connector housing assembly is integrally formed with two or more claw, each claw all extends to the front of parent shell and forms elastic cantilever structure, each claw surrounds a breathing mouth together, the outer peripheral face of public housing is provided with the draw-in groove corresponding with claw, therefore, in the process used, when needing plug and socket plugs together, the front end of public housing is only needed to be inserted in parent shell, claw is by the draw-in groove that snaps under the effect of natural resiliency power on public housing, thus plug casing and Socket casing are locked together, locking mechanism is and originally processes with it at electric connector housing assembly, lock without the need to any appurtenances, thus the volume of electric coupler component can be reduced, reduce the space needed for electric coupler component is installed.
Further, for there is the situation of relative rotation after avoiding plug casing to plug together with Socket casing in positioning key and location notch; After the gap-forming keyway between two claws, keyway can be processed in addition specially again, thus the processing technology to parent shell can be simplified, cut down finished cost; The section of being sealed and matched and seal can realize interfacial seal therebetween after plug casing and Socket casing plug together.
