[embodiment]
For ease of better understanding the purpose of this utility model, structure, feature and effect etc., existing the utility model is described in further detail with embodiment by reference to the accompanying drawings.
As shown in Figure 1, electric connector of the present utility model, comprises an insulating body 1, is arranged at upper row's terminal 2 in insulating body 1 and ground plate 3, and be assembled in lower row's terminal 4 of insulating body 1, be coated on the metal shell 5 outside insulating body 1.
As depicted in figs. 1 and 2, the tongue piece 11 that insulating body 1 comprises a base portion 10 and extends forward from described base portion 10, because described tongue piece 11 is thinner, in the present embodiment only by upper row's terminal 2 and ground plate 3 together insert molding in described insulating body 1, the row's of making terminal 2 part is revealed in the upper surface of tongue piece 11, ground plate 3 is embedded in tongue piece 11, lower row's terminal 4 then first insert molding in collets 6, overall package is in the lower surface of tongue piece 11 again, the lower surface correspondence of described tongue piece 11 is provided with the multiple grooves for accommodating lower row's terminal 4, lower row's terminal 4 part is revealed in the lower surface of tongue piece 11.In other embodiments, also can be upper row's terminal 2, lower row's terminal 4 together with ground plate 3 insert molding in same insulating body 1, or upper row's terminal 2, lower row's terminal 4 are all arranged on the both sides of ground plate 3 with assembling mode.
With reference to Fig. 1 and Fig. 4, upper row's terminal 2, lower row's terminal 4 are that symmetry axis is symmetrical up and down with described ground plate 3, and in each row's terminal 2,4, all terminals are positioned at same level height, and all equal with the thickness of row's terminal.Include high-speed terminal A and non-high-speed terminal B in each row's terminal, described high-speed terminal A comprises the difference signal terminal of a pair transmission USB3.0 signal, and described non-high-speed terminal B comprises earth terminal, power supply terminal and USB2.0 terminal etc.In the present embodiment, often arrange terminal and be followed successively by from left to right: an earth terminal, a pair USB 3.0 terminal, a power supply terminal, a reserved terminal, a pair USB 2.0 terminal, a reserved terminal, a power supply terminal, a pair USB 3.0 terminal, an earth terminal.
As shown in Figures 2 and 3, described ground plate 3 strikes out tabular by metal material, and is embedded in thinner tongue piece 11, by filling insulating material between upper row's terminal 2 and ground plate 3, is then separated by the insulating material below ground plate 3 between lower row's terminal 4 and ground plate 3.The different piece of ground plate 3 has different thickness, for convenience of describing and understanding, becomes the thickness of the first dull and stereotyped 31 and second flat board 32, first flat board 31 to be less than the thickness of the second flat board 32 ground plate 3 herein according to thickness different demarcation.Because ground plate 3 has two places thinning in the present embodiment, because which form two first dull and stereotyped 31 and three the second flat boards 32, and to be positioned at outermost place be the second thicker flat board 32.The plate face of described first flat board 31 is not concordant with the plate face of described second flat board 32, and particularly, the upper surface of the first flat board 31 is lower than the upper surface of the second flat board 32, and the lower surface of the first flat board 31 is higher than the lower surface of the second flat board 32.In other embodiments, also only row's terminal can be set in the side of ground plate 3, and different from thinning for correspondence position on ground plate 3 according to the position of high-speed terminal A, and the utility model is not limited thereto.
In the present embodiment, the horizontal both sides of ground plate 3 have extended back a grounding leg 33 on the second thicker flat board 32, described grounding leg 33 runs through base portion 10 rear portion in insulating body 1, and bending is downwards in order to be electrically soldered to the ground wire on a circuit board, to realize the earth shield function of whole ground plate 3.Do not need in the embodiment of ground connection at other, described ground plate 3 also can be one piece of simple metallic plate, does not need to arrange grounding leg 33 and carrys out ground connection.
In the present embodiment, second flat board 32 of ground plate 3 both sides also protrudes formation one buckling parts 34 respectively towards both sides, when in ground plate 3 inserted tongue 11, the both sides of described buckling parts 34 meeting projecting tabs 11, buckling parts 34 is arranged with a groove in order to the hardware (not shown) in clasp butt connector (not shown), and realizes hardware and ground plate 3 common ground simultaneously.In addition, ground plate 3 entirety protrudes forward the leading edge of described tongue piece 11 in order in electrical contact with butt connector.
As shown in Figures 4 and 5, wherein the upper and lower surface of two the first flat boards 31 all faces high-speed terminal A i.e. a pair USB 3.0 terminal, be arranged in two second of both sides dull and stereotyped 32 just to the earth terminal of non-high-speed terminal B, be arranged in middle second dull and stereotyped 32 just to the earth terminal of non-high-speed terminal B, power supply terminal and USB2.0 terminal, reserved terminal.Because the thickness of slab of the first flat board 31 diminishes relative to the thickness of slab of the second flat board 32, thus the distance d1 between the lower surface of the upper surface of the first flat board 31 and high-speed terminal A (USB 3.0 terminal) can be greater than the distance d2 between the upper surface of the second flat board 32 and the lower surface of non-high-speed terminal B, distance d3 between the upper surface of the lower surface of the first flat board 31 and high-speed terminal A (USB 3.0 terminal) can be greater than the distance d4 between the lower surface of the second flat board 32 and the upper surface of non-high-speed terminal B, therefore, capacitive coupling C1 between first dull and stereotyped 31 and high-speed terminal A can be less than the capacitive coupling C2 between second dull and stereotyped 32 and non-high-speed terminal B, reach in this way and regulate high-speed terminal A impedance matching.
In addition, metal shell 5 forms a cavity volume around insulating body 1, inserts with the terminal on tongue piece 11 in electrical contact for holding for butt connector.
The utility model has following beneficial effect:
1. by ground plate 3 is just thinning to the thickness of slab at high-speed terminal A place, the distance between ground plate 3 and high-speed terminal A is made to be greater than distance between ground plate 3 and non-high-speed terminal B, thisly can not increase the shared height of ground plate 3 or thickness by the thinning mode of ground plate 3 itself, be conducive to the distance increased in thinner tongue piece 11 between ground plate 3 and high-speed terminal A, to reduce the capacitive coupling between high-speed terminal A and ground plate 3, realize the impedance matching of high-speed terminal A.
2. due to both sides and the leading edge projecting tabs 11 of ground plate 3, and the thickness of these parts is all greater than the thickness of middle thinned section, thus can ensure the intensity of projection such as buckling parts 34 grade, guarantee these parts can with abutment element good contact.
3. by upper row's terminal 2 and ground plate 3 together insert molding in insulating body 1 in, lower row's terminal 4 insert molding is assembled to mode below ground plate 3 after collets 6, be conducive to the intensity ensureing thinner tongue piece 11, guarantee that tongue piece 11 is unlikely to damage.
More than describe the explanation being only the preferred embodiment of the utility model in detail, non-the scope of the claims therefore limiting to the utility model, so all this creation of utilization specifications and the equivalence techniques change for it of diagramatic content institute, be all contained in the scope of the claims of this creation.
