DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Reference will now be made in detail to the embodiments of the present disclosure. The insertion direction is a front-to-rear direction.

Referring to FIGS. 1 to 13, an electrical connector 100 includes an insulative housing 2, a number of conductive terminals 4 arranged in two rows, a shielding plate 6, and a shielding shell 7 enclosing the insulative housing 2. The electrical connector 100 is of a sink-type that is suspended in a groove of a printed circuit board (not shown) in the electronic device (not shown).

Referring to FIGS. 1 to 13, the insulative housing 2 includes a base portion 21 and a tongue portion 22 extending forwardly from the base portion 21. The base portion 21 includes a number of front resisting grooves 211 surrounding a front end of the base portion and a number of rear resisting grooves 212 surrounding a rear end of the base portion. The insulative housing 2 further includes a pair of lateral slots 221 located at two lateral sides of the tongue portion for mating with a corresponded electrical connector. The tongue portion 22 defines an upper surface and a lower surface opposite to the upper surface. The tongue portion 22 includes a number of receiving grooves 241 respectively located at the upper surface and the lower surface. The insulative housing 2 includes a first insulator 23 and a second insulator 25. The first insulator 23 includes the base portion 21 and a first tongue portion 24 extending forwardly from the base portion 21. The first tongue portion 24 and the second insulator 25 form the tongue portion 22.

Referring to FIGS. 5 to 13, the conductive terminals 4 arranged in two rows include a number of upper terminals 41 and a number of lower terminals 42. Each conductive terminal 4 includes a front contacting portion 401 exposed to the upper surface or the lower surface of the tongue portion 22, a middle fixing portion 402 partially affixed to the tongue portion 22 and the base portion 21, and a rear soldering/tail portion 403 extending outwardly from the base portion 21.

Arrangement of the upper terminals 41 and the lower terminals 42 on the tongue portion 22 is generally symmetrical in the sense that orientation of the electrical connector can be flipped. As shown in FIG. 14, twelve terminal positions, A1 through A12 from left to right, are defined on the upper surface of the tongue portion 22 and twelve terminal positions, B1 through B12 from right to left, are defined on the lower surface of the tongue portion 22. The six upper terminals 41 occupy the positions A5, A6, A7, A8, A9, and A12 while the six lower terminals 42 occupy the positions B5, B6, B7, B8, B9, and B12. Each row of the conductive terminals 4 includes four first contacts 43 occupying the positions A5, A6, A7, A8, one power terminal occupying the position A9, and one grounding terminal occupying the position A12. The first contacts 43 are a detecting terminal occupying the position A5, a USB2.0 positive signal terminal occupying the position A6, a USB2.0 negative signal terminal occupying the position A7, and an auxiliary terminal occupying the position A8. The detecting terminal occupying the position A5, the USB2.0 positive signal terminal occupying the position A6, the USB2.0 negative signal terminal occupying the position A7, the auxiliary terminal occupying the position A8 and the power terminal occupying the position A9 are called intermediate terminals. There is a respective reserved space formed between every two adjacent terminals of the five intermediate terminals. The auxiliary terminal is disposed at eighth position A8 out of the twelve terminal positions on the tongue portion 22 and can be used for transmitting required signals as needed. There is no conductive terminal at the first through the fourth terminal positions, the tenth terminal position, and the eleventh terminal position in order to form a space. The space enlarges the distance between the conductive terminals 4, enabling the electrical connector 100 to conduct large current of about 3 A to 5 A. Each first contact 43 includes a front portion 431 and an ear 432 extending laterally from the contacting portion 401. The reserved space receives the ears 432 that is to be pressed by molds during manufacturing.

The upper terminals 41 and the lower terminals 42 are equal in number and each includes six conductive terminals 4. Each contacting portion 401 of the upper terminals 41 is positioned in reverse symmetry with respect to a respective one of the lower terminals 42. The auxiliary terminal could transmit auxiliary signal according to specialized demand increasing the diversity of the signal transmission.

Referring to FIGS. 5 to 13, the shielding plate 6 is planar and has a main portion 61. The shielding plate 6 further includes a left section 62, a right section 63 arranged in symmetry with the left section 62, and a connecting arm 64 connecting the left section 62 and the right section 63.

Referring to FIGS. 1 to 4, the shielding shell 7 includes a top wall 71, a bottom wall 72 opposite to the top wall, and a pair of lateral walls 73 connecting the top wall 71 and the bottom wall 72 for forming a mating room 700. The shielding shell 7 includes a number of front resisting portions 74 located at the top wall 71 and the bottom wall 72, a number of rear resisting portions 75 located at the top wall 71 and the bottom wall 72, a number of dimples or tubers 76 located at the top wall 71 and the bottom wall 72, and a number of fixing pins 77 located at the lateral walls 73. The front resisting portions 74 and the rear resisting portions 75 are bent and formed in the mating room 700 by shearing and forming operation. The tubers 76 protrude into the mating room 700 by stamping and forming operation. Corresponding shielding shell of a mating electrical connector contacts the tubers 76 for grounding. The fixing pins 77 are symmetrically disposed on both lateral walls 73 and are bent outwardly by shearing and forming operation.

Referring to FIGS. 1 to 14, the upper terminals 41, the lower terminals 42, the shielding plate 6 and the first insulator 23 are insert molded to be an integrated unit. Firstly, during insert molding, the upper terminals 41, the lower terminals 42, and the left section 62 and the right section 63 of the shielding plate 6 are resisted in the vertical direction by the mold. The first contacts 43 are resisted in the vertical direction by way of the ears 432. Secondly molten insulative material are insert molded with the upper terminals 41, the lower terminals 42, and the shielding plate 6. Eventually the mold is withdrawn and cutoff bridges of the conductive terminals 4 exposed to the receiving grooves 241 are severed.

The shielding plate is sandwiched between the upper terminals and the lower terminals. The contacting portion 401 of the upper terminals 41 are exposed to an upper surface of the first tongue portion 24. The contacting portion 401 of the lower terminals 42 are exposed to a lower surface of the first tongue portion 24. A number of front ends of the contacting portions 401 of the power terminals and the grounding terminals of the upper terminals 41 and the lower terminals 42 are embedded in a front end of the first tongue portion 24. The front portions 431 of the first contacts 43 of the upper terminals 41 and lower terminals 42 are embedded in the front end of the first tongue portion 24. The front portions 431 of the first contacts 43 of the lower terminal 42 are laterally offset with respect to the front portions 431 of the first contacts 43 of the upper terminal 41 for allowing the mold from resisting against and preventing the first contacts 43 of the two rows of conductive terminals 4 from connecting with each other. The soldering portions 403 of the upper terminals 41 and the lower terminals 42 are engaged in a row in a transverse direction.

The receiving grooves 241 are allocated among the first terminal position to forth terminal position, the tenth terminal position to the eleventh terminal position and between the first contacts 43. The lower surfaces of the power terminal and the grounding terminal of the upper terminals 41 are partially exposed to the receiving grooves 241. The upper surfaces of the power terminal and the grounding terminal of the lower terminal 42 are partially exposed to the receiving grooves 241. The ears 432 of the first contacts 43 of the upper terminals 41 and the lower terminals 42 are exposed to the receiving grooves 241. The left section 62 and the right section 63 of the shielding plate 6 are partially exposed to the receiving grooves 241. The ears 432 of the lower terminals 42, the connecting arm of the shielding plate 6, and the ears 432 of the upper terminals 41 are offset from each other in the front-to-rear direction.

The second insulator 25 is insert-molded with the integrated unit. The second insulator 25 fills in the receiving grooves 241 and encloses the front portions 431 of the first contacts 43. The two lateral sides of the main portion 61 extend outwardly from two sides of the tongue portion 22 for mating with the corresponded electrical connector.

The insulative housing 2 affixed with the conductive terminals 2 and the shielding plate 6 is assembled to the shielding shell 7 along a rear-to-front direction opposite to the front-to-rear direction. The front resisting portions 74 of the shielding shell 7 resist rearward against the front resisting grooves 211 while the rear resisting portions 75 of the shielding shell 7 resist forwardly against the rear resisting grooves 212 for fixing the insulative housing 2 in the front-to-rear direction and the rear-to-front direction. The fixing pins 77 are mounted to a printed circuit board (not shown) of an electrical device (not shown). The soldering portions 403 of the upper terminals 41 and the lower terminals 42 are soldered to the print circuit board.

In the embodiment, the shielding plate 6 is not connected with the shielding shell 7 rather they are connected with a mating electrical connector for grounding purpose. In other embodiments, the shielding plate 6 includes a pair of grounding pins (not shown) located at two sides of the main portion 61. The grounding pins extend outwardly from the base portion 21 to connect with an inner surface of the shielding shell 7 for grounding.

Compared with the prior arts, the electrical connector 100 of the present invention has a total of twelve conductive terminals 4, which not only meets USB2.0 specification, large current applications from 3 A to 5 A, and is intermateable with Type C plug, but also transmits auxiliary signals as needed. The ears 431 of the first contacts 43 contribute to the mold resisting against the first contacts 43 making the process easier and improving yield. Notably, on one hand, the left ear and the right ear of each contact are offset from each other in the front-to-back direction for preventing interfering with the ears of the neighboring contact in the same row; on the other hand, for the paired upper terminal and lower terminal aligned with each other in the vertical direction, the ears of the upper terminal are offset from those of the corresponding lower terminal in the front-to-back direction so as to prevent interference of the corresponding mold used for supporting the upper terminal and that used for supporting the lower terminal. It is also noted that as mentioned before the front portions 431 of the upper terminals 41 are offset from the front portions 431 of the lower terminals 42 in both the front-to-back direction an the transverse direction wherein on one hand, the front portions 431 of the upper terminals 41 are located behind the front portions 431 of the lower terminals 42; one the other hand, the front portions 431 of the upper terminals 41 are essentially aligned with the corresponding contacting portions 401 in the front-to-back direction while the front portions 431 of the lower terminals 42 are offset from the corresponding contacting portions 401 in the transverse direction. It is also noted that as shown in FIG. 7, the front portions 431 of the upper terminals 41 are hidden behind the first insulator 23 while the front portions 431 of the lower terminals 42 are exposed outside of the first insulator. Anyhow, the front portions 431 of the upper terminals 41 and those of the lower terminals 42 are both hidden behind the second insulator 25 which is applied upon the first insulator 23.
