Description

A kind of USB electric connector

Technical field

The utility model relates to electric connector field, specifically a kind of USB electric connector.

Background technology

The USB3.0 connector that discloses on the market at present conventional A type is comprised of two conducting end subgroups and insulating body, and the cooperation manufacture craft of conducting end subgroup and insulating body has three kinds:

The first is that the first conducting end subgroup and the second conducting terminal group are put into respectively plastic mould and be injection molded into two plastic cement; Then after bending, fit together respectively, reinstall plastic cement lid.The shortcoming of this design is: assembling flow path is more complicated, and size is difficult for management and control.

The second inserts respectively riveting in main body plastic cement after being the first conducting end subgroup and the second conducting end subgroup bending, finally packs lid into.The shortcoming of this design is: need the mould of exploitation more, and assembling flow path is complicated.

The third is that the first conducting end subgroup and the second conducting terminal bond pads portion are SMT leg, and a mold is put into injection mold moulding again after going out.The shortcoming of this design is: for tin pin, be only the product of SMT type, range of application is limited.

Utility model content

The purpose of this utility model is to provide a kind of USB electric connector, for tin pin, is the product of DIP type, meets existing user's user demand.

The purpose of this utility model is achieved through the following technical solutions:

A USB electric connector, comprising: shielding casing, is fixed on the insulating body in shielding casing, and is installed in the first conducting end subgroup and the second conducting end subgroup on insulating body; The first conducting end subgroup and the second conducting end subgroup include contact site, holding portion and weld part, and described weld part is DIP leg, and described the first conducting end subgroup and the upper and lower overlapping placement of the second conducting end subgroup, form two row DIP legs.

Wherein, described insulating body is by described the first conducting end subgroup and the upper and lower overlapping rear injection mold injection mo(u)lding of putting into of the second conducting end subgroup simultaneously.

Wherein, the weld part of described the first conducting end subgroup and the second conducting end subgroup is coupled on a PCB circuit board simultaneously, and this PCB circuit board has with described weld part two arranges DIP contacts one to one.

Wherein, described the first conducting end subgroup includes 4 conducting terminals, and described the second conducting end subgroup includes 5 conducting terminals.

Compared with prior art, the utility model embodiment has following beneficial effect:

1) mechanism part is few, and manufacturing process is simple, and cost is low, the easy management and control of product quality;

2) small product size is little, saves space, is applicable to toward miniaturization development;

3) conducting end subgroup provides two row DIP pin, has met user's user demand.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

In conjunction with the decomposition view shown in the three-dimensional structure diagram shown in Fig. 1 and Fig. 2 and Fig. 3, in the present embodiment, USB electric connector 100 comprises following part:

Shielding casing 40, has an accommodation space.

Insulating body 30, be arranged in the accommodation space of shielding casing 40, there is a hyoplastron 31, the end face of this hyoplastron 31 and bottom surface are respectively equipped with first end pilot trench 310 and the second terminal groove 311, first end pilot trench 310 and the second terminal groove 311, in order to each conducting terminal is spaced apart, produce and crosstalk to prevent from being in contact with one another.

The first conducting end subgroup 10, its structure as shown in Figure 4, is placed and is formed (as shown in Figure 4, comprising 4 conducting terminals) side by side by a plurality of conducting terminals, and each conducting terminal has a contact site 11, a holding portion 12 and a weld part 13.Contact site 11 is placed in first end pilot trench 310 when assembling; Holding portion 12 is extended to weld part 13; Weld part 13 is DIP pin, is a row of horizontal and arranges, for being coupled to the DIP contact on PCB circuit board.

The first conducting end subgroup 20, its structure as shown in Figure 5, is placed and is formed (as shown in Figure 5, comprising 5 conducting terminals) side by side by a plurality of conducting terminals, and each conducting terminal has a contact site 21, a holding portion 22 and a weld part 23.Contact site 21 is placed in the second terminal groove 311 when assembling; Holding portion 22 is extended to weld part 23; Weld part 23 is DIP pin, is a row of horizontal and arranges, for being coupled to the DIP contact on PCB circuit board.In manufacturing process, the first conducting end subgroup 10 and the first conducting end subgroup 20 are misplaced mutually, form two row DIP legs, as shown in Figure 6.

The structure of the PCB circuit board coupling with conducting end subgroup as shown in Figure 8, comprises two row DIP contacts, is respectively used to couple with the first conducting end subgroup 10, the second conducting end subgroup 20, and the effect after coupling with two conducting end subgroups as shown in Figure 9.

In the present embodiment, the manufacture method of D type HDMI connector 100 is: by the first conducting end subgroup 10 and the upper and lower overlapping placement of the second conducting end subgroup 20, form two row DIP legs, as shown in Figure 6; Then the two conducting end subgroups that are misplaced are up and down put into injection mold injection mo(u)lding insulating body 30 simultaneously, as shown in Figure 7; Again the insulating body of injection mo(u)lding 30 is fixedly installed in the accommodation space of shielding casing 40.

To sum up, the utility model is simple in structure, and manufacture craft is simple, and cost is lower, and the easy management and control of product quality is applicable to toward miniaturization development; And be applicable to DIP type product.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
