Embodiment

Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast description of drawings embodiment of the present utility model.

Fig. 1 is the three-dimensional exploded view of the utility model one preferred embodiment, and together with reference to shown in other each figure, from figure, can be clear that, the utility model mainly be by: insulating base frame 1, shielding casing 4 and the first terminal group 2 and second terminal group 3 that are immobilizated in insulating base frame 1 are constituted; The tongue 12 that insulating base frame 1 comprises base portion 11, extends forward from base portion 11, and from the base portion 11 both sides projection 14 that extends back, and enclose in 14 of both sides projections and to form holding part 15, be laid with elongated conduit 13 on the described tongue 12, insert for second terminal group 3, be provided with the location notch 16 that can supply second terminal group, 3 inlay cards in base portion 11 sidewalls and top in addition; The first terminal group 2, each terminal comprise first holding parts 21, extend and be exposed to first contact site 22 of tongue 12 from first holding parts 21, and extend first weld part 23 of insulating base frame 1 from first holding parts 21, and wherein first contact site 22 is a slab construction; Second terminal group 3, it is moulded according to insulating base frame 1 surface profile curved design, each terminal comprises second holding parts 31, extends and be exposed to second contact site 32 of tongue 12 from second holding parts 31, reach second weld part 33 that extends insulating base frame 1 from second holding parts 31, this second contact site 32 is the elastic bending structure; And be coated on the outer shielding casing 4 of insulating base frame 1.

During assembling, the first terminal group 2 is that first holding parts 21 is embedded in the insulating base frame 1 (as shown in Figure 2) in advance, and make first contact site 22 of the first terminal group 2 be exposed to tongue 12 leading edges, first weld part 23 of the first terminal group 2 then protrudes into 14 of the projections of both sides, insulating base frame 1 rear end, by the setting of described both sides projection 14, be subjected to the external force collision and crooked with first weld part 23 that prevents to embed forming.Second terminal group 3 is when punching press is manufactured, its external form is according to the external form curved design of insulating base frame 1, thereby insulating base frame 1 is only laid conduit 13 on tongue 12, and at base portion 11 surface configuration location notchs 16, can need not on insulating base frame 1 base portion 11, wear terminal hole for second terminal group, 3 location, can avoid destroying base portion 11 structures of insulating base frame 1 whereby, effectively prevent when high temperature tin stove, the plastics fracture takes place because of metal heat expansion or plastics thickness deficiency cause base portion 11.Second terminal group 3 is by location notch 16 backs (as shown in Figure 3) of second holding parts, 31 location assembling insulating base frames 1, second contact site 32 promptly is placed in the conduit 13 of tongue 12, this second contact site 32 is the elastic bending structure, and an Elastic Contact can be provided when using.The holding part 15 of wherein said insulating base frame 11 can embed a positioning block 5, but provide the location notch 51 of first,

second weld part

23,33 of fixing on this locating piece 5, prevent first, second weld part long and flexible distortion of 23,33 length (as shown in Figure 4).

Fig. 5 is the structure chart of another preferred embodiment of the utility model, first, second weld part the 23, the 33rd is positioned at the top of this electric connector, can be assemblied in the circuit board below whereby, and because first,

second weld part

23,33 length are short, therefore the configuration that can save locating piece 5, all same as the previously described embodiments as for other structure and assembling mode, so no longer superfluous statement.

Indulge the above, the utility model electric connector can be simplified the structure while of electric connector, take into account the stability of structure, prevent that the plastics thickness between terminal and terminal is thin excessively, the loosening phenomenon of terminal takes place, therefore no matter all be than the known configurations progress on the function, in the assembling, and it is not seen in public use, the existing utility application that in accordance with the law proposes.

The above only is the schematic embodiment of the utility model, is not in order to limit scope of the present utility model.Any those skilled in the art, equivalent variations of having done under the prerequisite that does not break away from design of the present utility model and principle and modification all should belong to the scope that the utility model is protected.
