Embodiment:
Please refer to Fig. 1 to shown in Figure 3, the concrete structure that it has demonstrated the preferred embodiment of the utility model includes insulating body 10, conducting terminal 20 and metal shell 30.
Wherein, this insulating body 10 includes pedestal 11 and hyoplastron 12, and this hyoplastron 12 extends forward in pedestal 11 one.
This conducting terminal 20 is fixed on the insulating body 10 by the mode of plug-in mounting or produced by insert molding (insert molding), and wherein, the contact site 21 of this conducting terminal 20 exposes the surface of hyoplastron 12, and the weld part 22 of this conducting terminal 20 stretches out outside the pedestal 11.
As shown in Figure 2, this metal shell 30 is coated on outside the insulating body 10, is used to prevent electromagnetic interference.This metal shell 30 is an iron material matter, it includes main body 31 and extended shell fragment 32 on this main body 31, described main body 31 is made up of the sidewall of roof, diapire and connection roof and diapire, and surrounds the cavity 301 of a hollow, is used to accommodate insulating body 10 and external plug; Described shell fragment 32 is provided with along the plug direction, the one end connects main body 31, and the other end is flexible contact site, and this contact site is prominent in the cavity 301 of metal shell 30, be used for contacting with external plug, with increase external plug with the contact engaging and separating force of this electric connector when inserting.
On the roof of this main body 31 and diapire, be provided with shell fragment 32, certainly, can be provided with shell fragment 32 too on the sidewall, each shell fragment 32 is having recess by punching press compression moulding on the inner surface of cavity 301, on the corresponding outer surface is even curface, so to form a dark rib structure 321, the inner surface of the elasticity junction of the recess of the dark rib structure 321 in the present embodiment between corresponding shell fragment 32 and main body 31, make shell fragment have better elasticity and intensity, but, also the recess of dark rib structure 321 can be arranged on the outer surface not as limit; Described dark rib structure 321 is used to increase the intensity of shell fragment, in present embodiment, thereby utilize to increase shell fragment 32 intensity so that connector further strengthen at the contact engaging and separating force of male and female when inserting.And this metal shell 30 extends fixing feet 33, and this fixing feet 33 is used to insert the external circuit board 40, so that metal shell 30 is firmly fixed on the circuit board 40.
Of particular note: in this creation, also can on metal shell 30, increase by an exterior sleeves, and shell fragment is arranged at (not shown) on the exterior sleeves, be not located on the metal shell 30, the structure of the shell fragment of metal shell 30 is identical in elastic piece structure on the exterior sleeves and the present embodiment, exterior sleeves reaches same effect, so can be taken as metal shell here and treat.
In addition, a bit need to prove in addition at this, the wall number of the metal shell in this creation can change because of the type difference of connector, that is to say not necessarily and will constitute by above-mentioned four walls, sometimes also can not need wherein roof or diapire, only need and connect the two side of roof or constitute and just can by roof by diapire and the two side that connects diapire.
The assembling process that present embodiment is described in detail in detail is as follows:
The assembling process of present embodiment is very simple, as shown in Figures 2 and 3, at first the mode by plug-in mounting or produced by insert molding (molding) is fixed in conducting terminal 20 on the insulating body 10, the contact site 21 of conducting terminal 20 is exposed outside the hyoplastron 12, and the weld part 22 of conducting terminal 20 is stretched out outside the pedestal 11.Then, metal shell 30 is set in insulating body 10 outer getting final product (as shown in Figure 1).
During use,, make the weld part 22 of conducting terminal 20 weld to be electrically connected and get final product with circuit board 40 by the fixing feet 33 of metal shell 30 being inserted and being fixed on the circuit board 40.When plug inserts or extracts, utilize each shell fragment 32, and cooperate and utilize dark rib structure 321 to make contact engaging and separating force obviously strengthen, plug smooth and easy.
Design focal point of the present utility model is: at first, be formed with dark rib structure by compacting scrobicula position on shell fragment, to change material behavior, the elasticity and the intensity of shell fragment are effectively strengthened, further increase contact engaging and separating force, make the insertion of external plug and extract to be more prone to, and can prolong connect-disconnect life, the convenience that uses is provided to the user.Secondly, its dark rib can be applicable in the metal shell of any material, all can effectively increase contact engaging and separating force, use flexibility height, and it is more obvious as if its effect that increases contact engaging and separating force of the metal shell that dark rib structure is applied to iron material matter, not only, also can reduce enterprise's production cost, improve enterprise profit to facilitating property of user.Moreover its dark rib structure structure has replaced the bright rib structure of tradition, can make the elasticity contact engaging and separating force obviously strengthen on the one hand, its dark rib is hidden in the metal shell on the other hand, can not expose outside the metal shell, make that the overall appearance of electric connector is attractive in appearance, visual effect is good.
The above, it only is preferred embodiment of the present utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
