Embodiment
Please refer to Fig. 1 and Fig. 2, shown in Fig. 1 and Fig. 2, be respectively this waterproof electrical connector of creating an embodiment 10 and explosive view thereof.Waterproof electrical connector 10 has water-proof function, and it is upper that it can be applicable to waterproof portable electronic devices (not illustrating), for example waterproof Smartphone.In the present embodiment, waterproof electrical connector 10 is for to meet the socket-type connector of micro universal serial bus (Micro USB) 2.0 specifications, but is not limited to this.
Waterproof electrical connector 10 comprises insulating body 11, metal shell 12, plural terminals 13, sheet metal 14, waterproof apron 15, marine glue 16 and film 17.Insulating body 11 comprises glue core 20 and hyoplastron 21, and hyoplastron 21 stretches out from glue core 20, and metal shell 12 plugs together space 22 around insulating body 11 formation.A plurality of terminals 13 are immobilizated in glue core 20, and one end of terminal 13 is positioned hyoplastron 21, and the side that the other end of terminal 13 deviates from hyoplastron 21 by glue core 20 passes.Sheet metal 14 is attached in the one side that hyoplastron 21 deviates from those terminals 13 and inserts in glue core 20, and sheet metal 14 can increase the bulk strength of hyoplastron 21 and glue core 20.Waterproof apron 15 is around the front end of metal shell 12, after waterproof electrical connector 10 is installed on described portable electronic devices, waterproof apron 15 can clogging waterproof electrical connector 10 and the shell of portable electronic devices between gap, avoid infiltration.
Referring to Fig. 1 to Fig. 3, Figure 3 shows that this metal shell of creating an embodiment 12.Metal shell 12 is jointless structure, particularly, metal shell 12 comprises that four side plate 121,122,123,124, four side plates 121,122,123,124 are connected to each other and form the aspect of rectangle substantially, and the medial surface of four side plates 121,122,123,124 plugs together space 22 around formation.Focus on, four side plates 121,122,123,124 do not have gap in joint each other, and the gap also producing without joining on each side plate 121,122,123,124, as shown in Figures 1 and 3.In the present embodiment, metal shell 12 is metal ejection formation (Metal Injection Molding, MIM) part, be that metal shell 12 is to adopt metal ejection formation fabrication techniques to form, four side plates 121,122,123,124 of metal shell 12 are to utilize metal dust, see through injection molding method and integrally formed, so the metal shell 12 of this creation can't produce the gap that produces headtotail place as the metal shell of prior art after bending and molding.
Please refer to Fig. 4, shown in Fig. 4, this waterproof electrical connector 10 of creating an embodiment does not add the aspect of marine glue 16.As shown in Figure 4, the rear inside that glue core 20 deviates from a side of hyoplastron 21 and four side plates 121,122,123,124 of metal shell 12 forms groove 23 jointly, on the wherein side plate 121 of metal shell 12, be provided with stop tab 24, stop tab 24 extends in groove 23, and stop tab 24 is that rear end from this side plate 121 forms breach 25 toward groove 23 inner bendings in these side plate 121 rear ends.Stop tab 24 is pressed on the side that glue core 20 deviates from hyoplastron 21, when have plug insert waterproof electrical connector 10 plug together space 22 time, the stress inserting can be fallen by stop tab 24 payments wherein a part of and stop the trend of insulating body 11 displacement backward, to avoid under long-term plug used, the displacement that insulating body 11 is possible and cause waterproof electrical connector 10 to damage.In the present embodiment, stop tab 24 and four side plates 121,122,123,124 are to see through metal ejection formation processing procedure and integrally formed; In other embodiments, stop tab also can be after four side plate moulding, more further see through cutting and bending moulding.
Please refer to Fig. 5, shown in Fig. 5, this waterproof electrical connector 10 of creating an embodiment has added the aspect of marine glue 16.As previously mentioned, the metal shell 12 of this creation itself is jointless structure, yet has gap between metal shell 12 and insulating body 11, while therefore making, needs further marine glue 16 to be coated in groove 23.Relation due to above-mentioned breach 25, for the ease of allow marine glue 16 can be in groove 23 curing molding and can not see through breach 25 and spill, therefore first film 17 is attached to metal shell 12 and sealing breach 25 on processing procedure after, again marine glue 16 is coated in groove 23, after marine glue 16 solidifies, marine glue 16 can be fixed in groove 23 and while gluing metal shell 12, stop tab 24, film 17, glue core 20 and those terminals 13, thereby fills the gap between metal shell 12 and insulating body 11.By the jointless structure of metal shell 12 own and the marine glue 16 in the gap between clogging metal shell 12 and insulating body 11, after waterproof electrical connector 10 is installed on described portable electronic devices, even if having liquid to be filled into plugging together in space 22 of waterproof electrical connector 10, also can not penetrate into the inner space of portable electronic devices.
Referring to Fig. 2 and Fig. 6, Figure 6 shows that this insulating body of creating an embodiment 11 and terminal 13.Glue core 20 comprises the first glue core 201 and the second glue core 202, hyoplastron 21 comprises the first hyoplastron 211 and the second hyoplastron 212, the second hyoplastron 212 stretches out from the first glue core 201, the first hyoplastron 211 stretches out from the second hyoplastron 212, and it is poor that the second hyoplastron 212 and the first glue core 201 form section, and that the first hyoplastron 211 and the second hyoplastron 212 also form is section poor.Those terminals 13 comprise plural the first terminal 131 and plural the second terminal 132, those the first terminals 131 are immobilizated in the first glue core 201, and one end of those the first terminals 131 is positioned the first hyoplastron 211, those second terminals 132 are immobilizated in the second glue core 202, the second glue core 202 is connected in the first glue core 201, and one end of those the second terminals 132 is positioned the second hyoplastron 212.Wherein, the first terminal 131 is for example for meeting the terminal of Micro USB 2.0 specifications, and the second terminal 132 is input and output (Input/Output, I/O) terminal.
In sum, a kind of waterproof electrical connector that this creation proposes, its metal shell itself is seamless link, therefore do not there is gap, do not need to add in addition again last layer plastic casing, just can reach the effect of waterproof, therefore can reduce thickness and the overall volume of housing, in addition, the metal-back system of this creation utilizes metal ejection formation to make, and the casing rigidity of metal ejection formation can be than using the higher of bending and molding.Compared to prior art, the waterproof electrical connector of this creation not only small volume and intensity higher, be not easy distortion and more durable.
Although this creation discloses as above with preferred embodiment; so it is not intended to limit this creation; anyly have the knack of this skill person; within not departing from the spirit and scope of this creation; when doing a little change and retouching, thus the protection range of this creation when depending on after the attached claim person of defining be as the criterion.
