Abstract
The invention discloses pins and a plug assembly with the same. A round through hole is formed in the middle of each plastic part embedding and ejecting part, and a Y-type prong is arranged on each connecting-out power source. The plug assembly comprises a pair of pins, a plastic part and a pair of adaptor metal elastic pieces, the plastic part embedding and ejecting parts of the pins make tight contact with the plastic part, through holes are formed in the adaptor metal elastic pieces and are suitable for the Y-type prongs to penetrate through, and the pair of adaptor metal elastic pieces and the pair of pins are tightly connected into one through riveting. The round through hole is additionally formed in the plastic part embedding and ejecting part of each pin, so that the reliability and strength of connection of the pins and the plastic part are higher; in addition, a round through hole of each connecting-out power source is changed into the Y-type prong with a C-type chamfer and a round chamfer, the Y-type prongs will not fracture when extending to the two sides, and secondary damage to the pins of the plug assembly is avoided.
Description
Technical field
The present invention relates to connector, particularly relate to a kind of pin and there is the plug-assembly of this pin, for attaching plug.
Background technology
The volume requirement of people to the electronic product of band plug is more and more higher, requires that product is small and exquisite, light, also wants firm, safety.So the volume as the electronic product of the band such as Homeplug, smart jack plug is just more and more less; Again because as the electronic product of the band such as Homeplug, smart jack plug always with forceful electric power (AC220V), thus the conductivity of the pin of plug (or claiming metal PIN needle) and reliability just extremely important.
In order to meet conductivity and the fail safe of plug, the national regulations thickness (t) of plug base pin, width (b), spacing (F) and the requirement of height (R) equidimension.Therefore, in the design of plug series products, above-mentioned size must meet the standard of safety.So, under the prerequisite meeting safety standard, how to design reliable structure and just seem extremely important.
As shown in Figure 1, the pin 10 of conventional male prongs can be divided into three parts: safety criteria section 101, imbed jetting plastic part part 102 and pick out power unit 103; Safety criteria section 101 designs according to the standard size of safety, the limited space of improvement; Imbedding jetting plastic part part 102 is imbed plastic parts part, is pin 10 and the coupling part of plastic cement structure, needs to consider structural reliability; Picking out power unit 103 is confirm plug base pin 10 and the connected mode receiving power unit.
Can know from description above, the Curve guide impeller space of plug base pin 10 mainly concentrates on to be imbedded jetting plastic part part 102 and picks out power unit 103.And the plug base pin 10 of routine is designed with two heavy stands imbedding jetting plastic part part 102, increase the connectivity of plug base pin 10 and plastic parts; Pick out power unit 103 and be designed with a circular hole, adopt source of welding current line 11 mode to be derived by electric current, as shown in Figure 2.
As shown in Figure 1, the jetting plastic part part 102 of imbedding of conventional male prongs pin 10 only devises two heavy stands, makes the reliability of pin 10 not enough like this, and when using the product of pin 10 to do drop test and testing drum, pin 10 is yielding.In addition, as can be seen from Figure 2, conventional male prongs pin picks out power unit 103 and is connected by manual welding with power line 11, because power line 11 and plug base pin 10 are all smaller parts, so when both weld, operation can be more difficult, adds time and the human cost of assembling.Meanwhile, when welding, the high temperature that electric welding produces can be transmitted on pin 10, also easily causes pin 10 to be connected distortion with plastic parts.
Summary of the invention
The object of the invention is for solving current plug base pin and plastic parts connection reliability is poor, power line and pin adopt and are welded to connect, operation easier is large, and welding high temperature easily conducts to plastic parts to be caused connecting distortion, makes the technical problem of this plug product in use easy deformed damaged.
In order to solve the problems of the technologies described above, on the one hand, the invention provides a kind of pin of plug, described pin comprises safety criteria section, imbeds jetting plastic part part and pick out power unit, the described bilateral symmetry imbedding jetting plastic part part is provided with heavy stand, described in imbed jetting plastic part part middle part be provided with manhole.
Further, pick out power unit described in and there is Y type fork mouth.
Further, the symmetrical top of described Y type fork mouth has C type chamfering.
Further, the bottom of described Y type fork mouth has rounded corners.
On the other hand, the invention provides a kind of plug-assembly, comprise above-mentioned any pin a pair, plastic parts and switching metal clips a pair, described pin imbed jetting plastic part part and described plastic parts close contact, described switching metal clips is provided with through hole, the size of described through hole is adapted to pass through described Y type fork mouth, by transfer described in a pair metal clips respectively with pin described in a pair closely riveting connect as one.
The present invention is on conventional male prongs pin basis, on the one hand, a manhole has been increased newly in the jetting plastic part part of imbedding of pin, plug base pin and the contact imbedding jetting plastic part can be increased, namely have more plastic cement area to wrap up plug base pin, make pin have higher reliability and intensity, guarantee that product with this pin is in drop test and testing drum, plug base pin is indeformable, smoothly by test, can ensure that bulk article in use not easily deforms and damages; On the other hand, pick out power unit and change Y type fork mouth with C type chamfering and rounded corners into by manhole, during plug out-put supply with this pin, the power unit that picks out without power line and pin welds and exports, but go out with metal clips switching, the power unit that picks out of pin adopts riveting to be connected with switching shell fragment, namely the hole that a design size is corresponding to Y type fork mouth on switching shell fragment, then mate with Y type fork mouth with the hole of switching shell fragment, riveting Y type fork mouth again, makes plug base pin and switching shell fragment close contact.During the Y type fork mouth riveting of plug base pin, because Y type fork mouth exists rounded corners, so there is not situation about rupturing when Y type fork mouth can be made to expand to both sides, namely add the intensity of Y type fork mouth, allow it can bear larger riveting power.In addition, riveting only needs corresponding tool just can easily complete, and can not produce high temperature, can not cause man-made further destroy to plug base pin, also correspondingly improves the assembling speed of product line, reduces the human cost of production.
