Abstract
The present invention relates to an electric connector which at least comprises an insulating body, a plurality of terminals, a shading component which coats the insulating body and a bent elastic sheet, wherein the insulating body is provided with a plurality of terminal channels used for containing terminals and a recess which is arranged on the lower part of the butted end of the insulating body; the insulating body is provided with a slot along the insertion direction of a butting connector; the bent elastic sheet is inwards bent along the insertion direction of the butting connector. The bent elastic sheet is fixed and kept in the corresponding slot of the insulating body by a plurality of convex spines on both sides so as to achieve the goal of steadily connecting with the insulating body and fixing and holing other butting connectors.
Description
The relevant a kind of electric connector of the present invention refers in particular to a kind of electric connector that is located on the circuit board that is used to organize.
For the consideration to electric component deploying on the circuit board, industry needs development and Design that a kind of group of electric connector that is located at circuit board bottom surface arranged, and the plug surface of this electric connector has notch part, helps correctly docking with butt connector.And be custom when adapting to the user and inserting, need to keep the pin connector direction of insertion constant.For guaranteeing the stability of pin connector, electric connector need be provided with the elasticity holding unit usually.As shown in Figure 1 be the fixation spring tab device that existing electric connector is adopted, this fixation spring tab device 1 roughly takes the shape of the letter U, comprise base plate 12 and from the base plate 12 both side edges sidewall 13 that vertical extent is provided with that makes progress, and be wholely set the abutting part 11 of bending at base plate 12 middle parts, this abutting part 11 inserts (not shown) direction along butt connector and bends inwards, respectively be provided with a through hole 14 (as shown in Figure 2) on the two side 13, be used for the electric connector insulating body on respective bump (not shown) be interlockingly connected, thereby fixation spring tab device 1 is fixed on the insulating body.
But the structure of fixation spring tab device 1 is comparatively complicated, so its mfg. moulding die structure is also comparatively complicated, thereby causes the manufacturing cost of electric connector to increase.Simultaneously, fixation spring tab device 1 only is by through hole 14 of its two side 13 and the respective bump snapping on the insulating body, and then be combined on the insulating body, therefore the combination of the two is not very firm, after butt connector and electric connector repeatedly insert/extract, fixation spring tab may insulate certainly because of snapping is unstable and come off on the body, thereby can't realize really that it is used for the function of fixing butt connector.
Main purpose of the present invention is to provide a kind of electric connector with bending shell fragment of simple structure.
Another object of the present invention is to provide a kind of electric connector, can firmly combine between this bending shell fragment and insulating body with bending shell fragment of a damascene structures.
The objective of the invention is to be achieved through the following technical solutions: this electric connector comprises insulating body, the some terminal in the terminal channel that insulating body offers, the shading member that is coated on the insulating body periphery and bending shell fragments of being housed in.Wherein the bottom, butt end of insulating body and butt connector grafting offers alcove, and this alcove offers a slit along the direction of insertion of butt connector in insulating body, and the bending shell fragment includes kink, connecting portion and holding part.Wherein kink is along direction lateral buckling in the alcove of insulating body of butt connector insertion, it comprises head, convex surface, transition face, wherein convex surface is a little more than head, be used for when butt connector inserts, be resisted against on the butt connector, rely on the elasticity retain strength that kink provided to make butt connector stablize fixing.The transition of transition face from the kink to the connecting portion, connecting portion is connected between kink and the holding part, and be arranged in parallel with the butt connector direction of insertion.What link to each other with connecting portion is holding part, and its front end is provided with introduction part, respectively is provided with some protruding thorns in its both sides, this protruding thorn can with the above-mentioned rigid interference of slit inwall, thereby make the bending shell fragment firmly be plugged in the insulating body.
Compare with prior art, the invention has the advantages that: the holding part of bending shell fragment is provided with some protruding thorns, this protruding thorn can with the rigid interference of the inwall of above-mentioned slit, thereby the bending shell fragment firmly is plugged in the insulating body, and still has the function of fixing butt connector after guaranteeing repeatedly to plug.Simultaneously, the bending shell fragment adopts damascene structures to be retained in the insulating body, rather than relies on existing used through hole to be buckled on the insulating body, so the structure of its mfg. moulding die is comparatively simple, and then can effectively reduce the manufacturing cost of electric connector.
The invention will be further described below in conjunction with accompanying drawing and preferred embodiment.
