Background technology
For example at US 5,486, expression and narrated a kind of electric socket device in 117 as starting point of the present invention.Plug-in connector possesses a releasable locking device, and it comprises two leaf spring shape kayser lugs that curved by metallic plate, and they are at the grafting side upper process of plug, and can snap in the breach that is equipped on the utensil socket.In order to throw off locking device again, on the narrow side of plug, load onto and be designed to flexible button with mutual opposed version.If these buttons are pressed, just spring clip arrives such position, when this position, plug can not insert in the socket basically with making the effort or extracts in socket.Device is designed to so in addition, even make that being provided with operation release button plug after surpassing certain power also can be plugged on socket, or extracts in socket.This tension can not cause connecting harness damage or the situation of pulling apart under be welcome.
Can set up with regard to the socket connection aspect with regard to not operating the locking button, this plug-in connector is favourable, for operate the locking button need spend certain, but very little power.There is such possibility on the other hand, realizes the socket connection that does not in fact make the effort by means of operation locking button.For the disengagement of socket connection too.Carry out so wittingly if desired, so just operation locking button.If on plug-in connector, act on the pulling force that to tolerate on the other hand, just socket connection is thrown off automatically so.
The shortcoming of known plug-in connector is: elasticity is monolateral stretches out from plug with overhanging in locking, makes its bending easily, makes the socket connection function suffer damage or even becomes impossible.
Summary of the invention
Purpose of the present invention is as follows, from by US 5,486, the plug-in connector of 117 known types sets out and forms a kind of like this device in this wise, make when the socket connection state of plug-in connector, to form a reliable coercive force, but socket connection is thrown off without a doubt after overcoming certain power.Here especially pay attention to, avoid locking mechanism crooked easily or that can vitiablely freely overhang.
The present invention achieves this end as follows, a kind of electric socket device is proposed, comprise a utensil socket and a plug that matches with this utensil socket, wherein the utensil socket comprises a plastic casing of waiting to be contained on the printed circuit board, the contact that conduction between the conducting wire that is used for plug contacts and printed circuit board (PCB) connects is housed in this plastic casing, this male connector has a grafting boss in front, in a spliced eye that matches that is inserted into the utensil socket, the grafting boss is provided with the locking mechanism of at least one elastic deflection at least on one surface, this locking mechanism and an interior corresponding locking mechanism acting in conjunction of the spliced eye of utensil socket, releasable locking device as plug-in connector, it is characterized in that: locking mechanism and/or corresponding locking mechanism are formed by a belling in the contact pin, and this contact pin is severed from a spring plate piece by some longitudinal cuts but kept being connected with spring plate piece with two lug ends material sealing ground.
Therefore cardinal principle of the present invention is: locking mechanism and/or corresponding locking mechanism by a latch plate contact pin simply punching press form, wherein characteristics are, this latch plate contact pin is formed by the only longitudinally free stamping-out of spring plate piece, but keeps and the fixedlying connected of spring plate piece with two lug ends.Therefore form one or two lug ends and be connected leaf spring on the spring plate piece, therefore the free end that it does not stretch out can not be able to be caused its thing crooked or damage stumble being configured as on the locking mechanism of belling.
Obtain another unexpected advantage simultaneously.Because latch plate contact pin keeps being connected this fact in two lug ends with spring plate piece, impact the contact pin that causes being cut into and extend with respect to its reset condition.That is to say that stretching appears in spring tab portion branch, causes the flow harden in the Stamping Area.This causes this " punching press leaf spring " stable especially again, so it can be made by thin especially material, but still firm especially.
The present invention has a mind to abandon being used for the action button of locking mechanism, particularly actual tests shows in test, no matter be when plug-in connector is plugged together or all indicate available pressure point when being used to throw off, make and set up socket connection or disengagement reliably to the user is clear.The required power that overcomes should arrive for a short time when socket connection is not intended to unclamp on the other hand, makes it less than the damage that causes the socket connection part.The present invention meets this requirement with outstanding method.
In a kind of preferred construction, spring plate piece is equipped on cable plug and makes the Spring Card heel piece, and it can be embedded on the grafting boss of cable plug.The Spring Card heel piece is suitable in manufactory carrying out when the connector moulding by interlocking assembling.
Next is suitable for, and when the cross section of grafting boss was flattened rectangular, locking mechanism was made of a part of spring plate piece, and this part is equipped on the contact opposed wide of grafting boss.Determine layout in this way in this wise, make the Spring Card heel piece cover whole wide of the grafting boss, thereby additionally significantly help usually the mechanical stability of the grafting boss formed by plastics.In addition also can, with spring plate piece as barricade, if plug-in connector requires disturbing the width of cloth to penetrate shielding.
By another architectural feature of the present invention be, spring plate piece surrounds the narrow side of plug grafting boss, and is contained in the grafting boss and the roughly suitable groove of material thickness spring plate piece.Therefore the appearance profile of spring plate piece and grafting boss is fully integrated, will not form the turning or the seamed edge of projection, has therefore got rid of the effect of mechanical failure power in every respect.
Advantage of the present invention is in another kind of structure, and the corresponding locking mechanism that is equipped on the utensil socket constitutes from moulding plate supporting tongue piece that cut and terminal bending by one.If the arc or sleeve shaped of moulding plate is surrounded the plastic casing of utensil socket here, and the supporting tongue piece passes a window shape breach of plastic housing, so that contact with the locking mechanism of plug, is favourable.
Locking mechanism preferentially is a spring contact pin, and the supporting tongue piece advantageously do or be provided with to such an extent that be rigidity basically.Can be arranged in the power that plug-in connector is plugged on together or occurred when throwing off thus best, and the coercive force that alleviates tension force.
In a kind of successful test structure, spring plate piece has the material thickness of about 0.2mm, and the moulding plate that surrounds the utensil socket is that the material of the rigidity basically of about 0.3mm constitutes by a wall thickness.
Can be advantageously used in by plug-in connector of the present invention and to reach reliable locking in working order and to guarantee all occasions that socket connection is thrown off voluntarily when certain pulling force occurring.Be particularly suitable for very microminiaturized plug-in connector by structure of the present invention, the jointing on the mobile phone for example, it should with the cable plug of a charger, for example one to be installed in the appliance plug of hands-free telephone device in the automobile or the like relevant.Also can be used for by US 5,486, the determined application of 117 plug-in connector just is used for connecting computer component, for example PCMCIAPC card.In the many example application that can imagine another is the socket connection that is used for the UBS input/output interface.

Fig. 2 presses the perspective view of grafting boss of the plug of Fig. 1,
Fig. 3 is by the front view that connects superincumbent plug-in connector that has of Fig. 2, and wherein socket is local disconnects,
The enlarged drawing of locking between Fig. 4 plug and socket,
The zoomed-in view of arrow V direction is observed on the edge among Fig. 5 Fig. 4.
Embodiment
Whole plug-in connector with 10 expressions comprises a plug 11 and utensil socket 12.
Can also see a cage type metal forming plate 15 among Fig. 1, it encases upside and two narrow sides of utensil socket 12 plastic casings 13 at least.This metal forming plate 15 can be used for utensil socket 12 is fixed on utensil or the conductive plate.Another possible function is as a barricade.
For the corresponding locking mechanism 16 that the present invention importantly forms on metal forming plate 15, it and the locking mechanism acting in conjunction of plug 11 are if plug 11 is inserted on the utensil socket 12 interior service positions.The acting in conjunction that the shape of locking mechanism 17 and corresponding locking mechanism 16 is sealed constitutes a locking device, so that at the part 11 and 12 of considering to prevent fixedly connected plug-in connector under the plug-in connector 10 unexpected situations of throwing off.
In addition as shown in Figure 1, locking mechanism 17 is arranged on the spring plate piece 18, and this spring plate piece encases whole wide 19 of plug 11 grafting boss 20, and surrounds the narrow side of grafting boss 20.
For the purpose of integrality, be also pointed out that plug 11 has a handlebody 21 and of being made up of plastics and is used to be connected tortuous protection tube 22 on the plug 11, unillustrated cable.
Fig. 2 more clearly represents the layout and the structure of the locking mechanism 17 of two grafting boss 20 that are equipped on cable plug 11 than Fig. 1.Can also be clear that, are flat thin spring plate pieces by its spring plate piece 18 that forms locking mechanism 17, and it extends on whole broad upper surface 19 and narrow side 23.Do not draw in Fig. 2, the arris of bottom surface is also clamped in the side of narrow bending.Monoblock spring plate piece 18 is made the Spring Card heel piece in this way.Spring plate piece 18 also extends in the handlebody 21 and additionally is fixed on the there in addition, particularly is cast in the there.
As seen from Figure 2, locking mechanism 17 is by forming from the belling 24 of narrow contact pin 25 surperficial convex-shaped projections.Contact pin 25 is severed by some longitudinal cuts 26 from spring plate piece 18.Here it is characterized in that two lug ends 27 of contact pin 25 keep being connected with spring plate piece 18 respectively.Therefore the end that do not stretch out of locking mechanism 17, locking mechanism 17 bendings may be hooked and be made to external impurities on the end that stretches out.
Secondly as Fig. 2 finding, a contact pin 25 that has belling 24 has than its original plane contact pin of only severing by otch 26 and has longer length.That is to say by distortion to form a length increment, this causes material extending to a certain degree, and itself causes flow harden, and this makes and particularly in its surface, becomes very hard and firm by locking mechanism 17.
Secondly certainly, the contact pin of staying of contact pin 25 partly directly is not fitted on the frosting of grafting boss 20 on spring plate piece the 18 plane in, but has certain even very little downward springing stroke.
Observing Fig. 3 can see, the belling 24 of locking mechanism 17 and corresponding locking mechanism 16 actings in conjunction, and corresponding locking mechanism is formed on the metal forming plate 15, and metal bending thing encases the plastic casing 13 of utensil socket 12.Other details by Figure 4 and 5 as seen.Here main is, corresponding locking mechanism 16 is bent into single-ended sever, the tongue piece from plane 28 fall homes of moulding plate 15 of rigidity basically, and pass a window shape breach 29 on the plastic casing 13 of utensil socket 12 in this wise, make locking mechanism 17 to contact with corresponding locking mechanism 16 shapes sealedly.
The fact is as Figure 4 and 5 are also further represented especially, no matter plug 11 and socket 12 be plugged on a time-out still when plug-in connector is thrown off the free end of correspondence locking mechanism 16 stretch in the tracks of belling 24, make belling with respect to the downward elastic yield of Fig. 5.
Can be clear that especially that by Fig. 5 the convex shoulder 30 that works the locking mechanism 17 that prevents plug-in connector 10 disengagement effects designs suddenlyer than the convex shoulder 31 that slips on corresponding locking mechanism 16 when plug 11 inserts socket 12.Therefore the insertion of plug-in connector 10 is more mildly carried out, and opposite steeper convex shoulder 30 needs bigger power just can overcome, and consider when it is extracted.
It is very little to have the springing stroke that the leaf spring of locking mechanism 17 does.Must consider that for this reason particularly Figure 4 and 5 have been represented content of the present invention with the ratio of amplifying greatly.In fact the material thickness of spring plate piece 18 has only 0.2mm, and corresponding locking mechanism 16 has only 0.3mm thick.
Be also pointed out that at last layout and the structure of corresponding locking mechanism 16 on the moulding plate 15 of the insulator that surrounds utensil socket 12 recommended as good especially scheme on meaning of the present invention.Although can certainly with at least one locking mechanism directly that is to say that particularly material for example integrally formed on working of plastics as the boss of inner projection with unifying the material sealing.Select high-intensity, when wear-resistant plastic is used for insulator, LCP for example, this scheme is worth recommending especially.
