Refer to Fig. 1 to Fig. 5, be depicted as the preferred embodiment of electric connector of the present utility model, this electric connector 1 comprises an insulating body 2, a winding displacement 3 and a stiffening plate 4.

In insulating body 2, be provided with a passage 21 that penetrates insulating body 2 front and back ends, this passage 21 is provided with an open front 211 in insulating body 2 front ends, passage 21 is provided with an after-opening 212 in insulating body 2 rear ends, both sides in passage 21 are respectively provided with an interference part 22, this interference part 22 comprises a stopper section 221 and a buckle projection 222, this buckle projection 222 is provided with a guiding incline 223 and a vertical plane 224, this vertical plane 224 is intended for stopper section 221 and arranges, and this guiding incline 223 arranges back on stopper section 221.In addition, insulating body 2 is also provided with a connection buckle 23, and this connection buckle 23 is provided with grab 231 in order to be connected with the mutual buckle of a butt connector (not illustrating).

In the present embodiment, stopper section 221 and the buckle projection 222 of interference part 22 are front-back staggered setting, use stopper section 221 and buckle projection 222 are positioned on different straight lines, and the processing procedure that is so beneficial to injection molding is made this interference part 22.In addition, buckle projection 222 consists of jointly upper protruding block 225 and lower protruding block 226, in passage 21, comprise the upper medial surface 213 and the lower medial surface 214 that be arranged in parallel up and down, upper protruding block 225 is located at medial surface 213, lower protruding block 226 is located at lower medial surface 214, upper protruding block 225 and lower protruding block 226 are oppositely arranged to form an opening 227 up and down, and so design is beneficial to interfere and is sticked in winding displacement 3.

Winding displacement 3 is arranged in the passage 21 of insulating body 2, and wherein winding displacement 3 front ends are provided with a contact site 31, and this contact site 31 is provided with a plurality of contacts 311, and it is outer to be exposed to outside insulating body 2 that contact site 31 extensions protrude from passage 21.In the present embodiment, contact site 31 extensions of winding displacement 3 protrude from open front 211, and the width of open front 211 is less than the width of after-opening 212

Stiffening plate 4 utilizes the mode setting of hot pressing laminating to be fixed on winding displacement 3, and itself and winding displacement 3 are arranged in the passage 21 of insulating body 2 simultaneously, wherein the both sides of stiffening plate 4 are respectively provided with a holding section 41, stiffening plate 4 front ends are provided with a support portion 42, these holding section 41 interference are sticked in interference part 22 so that winding displacement 3 is fixed on to insulating body 2, support portion 42 extends to contact site 31 and exposes to support those contacts 311 that protrude from insulating body 2, so can make those contacts 311 of contact site 31 can have enough mechanism's intensity to form stable electric connection when contacting with butt connector (not illustrating), so the thickness of working as stiffening plate 4 is thicker or material is harder, the contact site 31 of better support strength to winding displacement 3 can be provided.

It is worth mentioning that, in the present embodiment, in order to facilitate processing procedure, make the combining structure of this winding displacement 3 and stiffening plate 4, so it is rear just directly in drawing holding section, the both sides of stiffening plate 4 41 that stiffening plate 4 hot pressing are fitted in to winding displacement 3, because winding displacement 3 is identical with the width size of stiffening plate 4, thus the both sides of winding displacement 3 also simultaneously drawing go out to correspond to the alar part 32 of holding section 41.Another kind of selection is that the width size of winding displacement 3 is less than the width of stiffening plate 4, so the extensible both sides that protrude from winding displacement 3, the holding section 41 of stiffening plate 4 both sides are sticked in interference part 22 to interfere.

In the present embodiment, the height size of passage 21 is greater than the summation of the thickness of winding displacement 3 and stiffening plate 4 slightly, the width size of passage 21 is greater than the width size of stiffening plate 4 slightly, in other words, the large I of the height and the width of passage 21 offers respectively the enough upper and lower action effects of locating with left and right of winding displacement 3 and stiffening plate 4.In addition, the upper protruding block 225 of interference part 22 and opening 227 sizes between lower protruding block 226 are less than the summation of the thickness of winding displacement 3 and stiffening plate 4, after the after-opening 212 of the alar part 32 of winding displacement 3 both sides and the holding section of stiffening plate 4 both sides 41 insertion passages 21, slip along guiding incline 223 is positioned between stopper section 221 and the vertical plane 224 of buckle projection 222 by opening 227 and engaging smoothly, the object that so winding displacement 3 is located before and after just can reaching with stiffening plate 4.

Be understandable that, in the present embodiment, the setting of stopper section 221 is close to open front 211, so to adjust the width size of dwindling open front 211, the contact site 31 of winding displacement 3 front ends is big or small with the width that the width size of the support portion 42 of stiffening plate 4 front ends must be matched with open front 211, protruding from outside insulating body 2 by open front 211 and extension smoothly, so the contact site 31 of winding displacement 3 and the width size of the support portion 42 of stiffening plate 4 are less than the width size of after-opening 212.

It is worth mentioning that, the support portion 42 of the contact site of winding displacement 3 front ends 31 and the stiffening plate 4 front ends portion that connects 5 that jointly partners, this docking section 5 is whole to be exposed to outside insulating body 2, so the mechanical strength of docking section 5 is provided by support portion 42.In addition, the docking section 5 only jointly being formed by contact site 31 and support portion 42, because it is simple in structure and thinner thickness, so applicable to the butt connector of slimming.Moreover, when selecting the stiffening plate 4 of different-thickness to fit with winding displacement 3 hot pressing, not only can change the mechanical strength of docking section 5, also can change the thickness size of docking section 5 simultaneously, therefore its thickness size can elasticity be adjusted in the docking section 5 of this novel electric connector 1, so more can be adapted to the slim butt connector of different slot sizes.

In sum, this novel electric connector is to utilize straight forming one interference part in the penetration channel of insulating body, and the direct stamp of front end one holding section at winding displacement, when winding displacement is assembled in insulating body, this holding section can be interfered and is sticked in interference part so that winding displacement is fixed on to insulating body, the structural strength that so can effectively solve existing electric connector not and assemble difficult shortcoming, is used the demand that meets client.In addition, the docking section of the electric connector that this is novel only consists of jointly the contact site of winding displacement front end and the support portion of stiffening plate front end, so the large I of its thickness is adjusted by the thickness of the stiffening plate of selecting in advance, therefore can adapt to the butt connector that is matched with slimming.

Above-described embodiment just lists expressivity principle of the present utility model and effect is described, but not for limiting the utility model.Any person skilled in the art person all can, under spirit of the present utility model and scope, modify to above-described embodiment.Therefore, rights protection scope of the present utility model, should be as listed in claims.
