Abstract
The utility model discloses a contact element and a fixing structure thereof and a printed board electric connector provided with the structure. The contact element is provided with at least one circular step-like barb structure that is in interference fit with a corresponding insulator mounting hole; a circular groove is arranged on at least one side of the outer sides of two ends of the bar structure on the contact element; since the contact element adopts the special fixing structure, namely, a barb compulsory mounting structure and a circular groove buffer structure, on the inner wall of the insulator mounting hole, a deformation body extrusion-deformed by the interference fit of the barb structure of the contact element can be held in the circular groove, thereby causing a deformed insulator to be buffered by the circular groove when the barb is compulsorily mounted so as to prevent the insulator from leaking, solve the problem that the compulsory mounting printed board electric connector of the contact element is difficult to be welded with a printed board, shorten assembling time and lower assembling difficulty.
Description
Technical field
The utility model relates to technical field of electric connectors.
Background technology
Contact installing hole in the contact of existing printed board electric connector and the insulator is to be connected by the interference fit that strong dress is out of shape, after the insulator of electric connector is subjected to contact crimp, owing to do not have the space between the installing hole of interference fit and the contact, the insulator of distortion will overflow from the position, aperture of contact installing hole, cause the edge, aperture of contact welding position uneven, cause contact to be difficult to weld with printed board.
The utility model content
The purpose of this utility model is to provide a kind of plug-in mounting fast to cooperate the contact fixed structure that can not cause insulator to overflow again, the printed board electric connector that the employed contact of this structure is provided simultaneously and uses this contact fixed structure.
The technical scheme of printed board electric connector of the present utility model: a kind of printed board electric connector, comprise connector shell and inner insulator, contact thereof, contact is plugged in the interior installing hole of corresponding insulator, at least one contact in the described electric connector is provided with at least one place annular table scalariform hangnail structure with corresponding insulation body installing hole interference fit, and at least one side on the contact in the outside at described hangnail structure two ends is provided with groove structure.
The end face of the small end of described hangnail structure has the circular arc chamfering to big end transition.
Described connector shell inwall is provided with the annular barb of protrusion, is connected by this hangnail electric connector housing and the insulator that inserts in it.
The technical scheme of electric connector contact of the present utility model: described contact is provided with at least one place annular table scalariform hangnail structure, on the contact in the outside at described hangnail structure two ends at least one side be provided with groove structure.
The end face of the small end of described hangnail structure has the circular arc chamfering to big end transition.
The technical scheme of the fixed structure of electric connector contact of the present utility model is: the fixed structure of electric connector contact, comprise insulator and its inner contact, contact plugs in the installing hole that is fixed in the corresponding insulator, it is characterized in that: described contact is provided with at least one place annular table scalariform hangnail structure with corresponding insulation body installing hole interference fit, at least one side on the contact in the outside at described hangnail structure two ends is provided with groove structure, is subjected to contact hangnail structure interference fit extruding on the described insulator installing hole inwall and the deformable body of distortion is taken in by described groove structure.
The end face of the small end of described hangnail structure has the circular arc chamfering to big end transition.
Contact of the present utility model is owing to adopted special fixed structure on one's body at contact: the strong assembling structure of hangnail+annular groove buffer structure, the deformable body that is subjected to the extruding of contact hangnail structure interference fit on the insulator installing hole inwall and is out of shape can be taken in by groove structure, thereby the insulator of hangnail distortion when strong dress is cushioned by groove structure, avoided the insulator overflow problem, solved contact and adorned formula printed board electric connector by force and be difficult to problem with the printed board welding, when having shortened the assembler and assembly difficulty.
In addition, the end face of the small end of the hangnail structure in the utility model has the circular arc chamfering to big end transition, and this circular arc chamfering has slick and sly guide effect when contact is adorned the installing hole that inserts the insulator at place separately by force, be convenient to the insertion of contact.
In addition, the shell of electric connector of the present utility model and insulator plug together fixing by the strong dress of the hangnail structure on the outer casing inner wall, make its assembling very convenient quick.
