Abstract

The utility model discloses an electric connector, which comprises an insulating main body, a plurality of conducting terminals inserted on the insulating main body and a shielding casing body. The shielding casing body is partially covered in the insulating main body at least, comprises a top wall, a bottom wall and two side walls and is provided with at least a holding part, and the holding part comprises a main body part arranged at the outer side of the side wall, a connecting part used for connecting the main body part and the front edge of the side wall, a first pin and a bending part positioned between the main body part and the pin. Because the holding part is arranged on the shielding casing body in the electric connector of the utility model and extends out from the front edge of the side wall of the shielding casing body, the arrangement of the position of the other structural components on each wall of the shielding casing body can not be influenced, thus avoiding from arranging redundant holes on the lower bottom surface to ensure that the material on the bottom wall is more sufficient and avoiding the fracture of the electric connector.

Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector.

[background technology]

Existing electric connector, as shown in figure 10, it comprises insulating body (figure does not show), shielding casing and is located in the interior terminal of insulating body (figure does not show).Wherein shielding casing is included in the insulating body outside, in case electromagnetic interference.This covers shell 1 and comprises roof 10, diapire 11, left side wall 12 and right side wall 13.11 liang of middle side parts of diapire are provided with first groove 111, second groove 112.Near left side wall 12, right side wall 13 both sides stamp out two pins by diapire 11, are respectively pin 121 and pin 130, so that electric connector is fixed on the circuit board.Two pins by two side 12,13 outside extensions downwards, just form described the 3rd groove 113 respectively after these pin 121 drawings, just form described four-way groove 114 after pin 130 drawings.And the 3rd groove 113 and parallel respectively first groove 111, second groove, 112 fronts of being positioned at of four-way groove 114.For the designer, because pin is to borrow material and generate from diapire, also might borrows material and generate, so it will have influence on the layout of the position of other each structure member on diapire, left side wall and the right side wall from sidewall, be not easy to design; And because between first groove and the 3rd groove, and the distance between second groove and the four-way groove is very near, coupling part between them is just very weak, for the user, after repeatedly plugging, electrical connector plug is easy to the coupling part between two grooves on the electric connector diapire is broken like this.And when shielding casing 1 is inserted in the butt joint 41 of plug 4, and dock with electric connector, because butt joint 41 is provided with two stuck points 411, stuck point 411 at first passes through groove 113 and 114 during butt joint, form buckle respectively at groove 113 and 114, needing then to continue inwardly to peg graft just can form buckle with groove 111 and 112, and this snapped-in position just can make the conducting strip (figure is mark not) of plug 4 form electric connection with connector terminals at this moment.Like this for the user, when stuck point when groove 113 and 114 forms buckles, just take for butt joint 41 easily and dock fully, cause the electric connection instability between plug 4 and the electric connector, the influence use.

Therefore, be necessary to design a kind of new electric connector, can overcome above-mentioned defective.

[summary of the invention]

The utility model electric connector, the setting of the pin on its shielding casing can not have influence on the layout of the position of other structure member on each wall of electric connector, convenient design.

The utility model electric connector, this electric connector comprises: an insulating body; Plurality of conductive terminals is inserted on this insulating body; An and shielding casing, it is coated in this insulating body to small part, this shielding casing comprises a roof, a diapire and two side, this shielding casing is provided with at least one holding parts, described holding parts comprises that the main part, of being located at the sidewall outside is used to connect connecting portion, one first pin of main part and sidewall leading edge, and the kink between main part and pin.

The utility model electric connector is because shielding casing is provided with holding parts, this holding parts is that the sidewall leading edge by shielding casing extends out, therefore can not influence the layout of other structure member position on each wall of shielding casing, and so also can avoid offering on the bottom surface unnecessary perforate, and make the material of diapire more sufficient, make male repeatedly plug the postpone electric connector can not occur yet the fracture, and when plug docks with this electric connector, because only offer two perforates corresponding on the diapire with two stuck points on the plug, therefore user's mistake of can not pegging graft, stuck point can directly be stuck in these two perforates, can one-time-reach-place; Because the pin that holding parts comprises is to link to each other with main part by kink, therefore do not need to change again the layout of circuit board, convenient welding simultaneously.
