Abstract

The utility model provides an electric connector grounding structure, which is suitable for a high-frequency transmission connector. A connecting piece is combined with a plurality of ground wires in a cable, which lets a high frequency electric connector raise the electrical character when transmitting signals; wherein, the connecting piece is provided with an alar part and a compression joint part; the connecting piece can cause the ground wire included in the cable to make the electrical contact with the grounding terminal; in addition, conductive terminals having preset directly extend on the connecting piece; thus the ground wire can be directly caused to be electrically connected with the connecting piece. Adopting the structure of the electric connector grounding structure can make the high-frequency connector implement have better electrical character and make the weld programs of the ground wire and the grounding terminal be saved. Therefore, all manufacturing processes can be shortened and the relevant cost can be reduced.

Description

The ground structure of electric connector

Technical field

The utility model relates to a kind of ground structure of electric connector.

Background technology

The ground structure of the connector on the computer main frame panel mostly is directly ground wire and earth terminal is done welding now.Because the continuous development of science and technology and the new line of environmental consciousness, the winding engineering of electronic industry is progressively towards unleaded making at present.

At present, the someone works out as U.S. Pat 6,489,563B1, and wherein, this patent utilization one ground strip (ground sleeve) is as contacting between ground wire and earth terminal; But this ground strip and earth terminal still need allow ground strip (ground sleeve) and earth terminal electrically connect by the program of welding;

Above-mentioned designing institute has a little lifting to electrical characteristic, but consider with production process for environmental protection and to have no to improve, except being easy to generate environmental pollution in the welding process, if add that welding not exclusively or uncertain, the easier phenomenon that causes disengaging, and then forfeiture ground connection effect, more very cause electrical characteristic not good; And old mode is the processing cost height not only, adds time-consumingly, more has the higher problem of fraction defective to produce, and so will increase its manufacturing cost for no reason, and this practice does not also meet economic benefit.

Summary of the invention

Main purpose of the present utility model is at above-mentioned defective, proposes a kind of ground structure of electric connector, to avoid above-mentioned defective.

For reaching above-mentioned purpose, connector of the present utility model has alar part and pressure contact portion, and this connector can be done electrically to contact and firm combination with earth terminal with containing the ground wire of being located in the cable; Again, this connector also can directly extend the conducting terminal of predetermined quantity, and ground wire and connector are electrically connected; Structure of the present utility model can make these high frequency connectors have better electrical characteristic, and makes ground wire and earth terminal remove the program of welding from, and shortens all processing procedures and relevant cost.

Now be described as follows with regard to conjunction with figs.:

Description of drawings

Fig. 1 is a three-dimensional assembling schematic diagram of the present utility model.

Fig. 2 is an enforcement view of the present utility model.

Fig. 3 is the solid assembling schematic diagram of another embodiment of the present utility model.

Fig. 4 is the enforcement view of another embodiment of the present utility model.

Embodiment

Shown in accompanying drawing 1 and accompanying drawing 2, be the enforcement view of three-dimensional assembling schematic diagram of the present utility model and this creation.

As shown in the figure: the utility model mainly includes a housing 1, be inserted in cable 5 and that predetermined quantity transmission terminal 2 and earth terminal 3, in the aforementioned housing 1 include predetermined quantity signal transmission unit 51 and ground wire 52 with aforementioned earth terminal 3 and ground wire 52 according to the electrical connector 4 that contacts of pressing program generation.

Wherein, this connector 4 can be the body that can do electrical contact material, and the appropriate position of this connector 4 has a pressure contact portion 41 again, and this pressure contact portion 41 can form the relief shape by the punching press program, produces better conducting contact effect thus.

By diagram as can be known, present embodiment is main to be combined signal transmission unit 51 earlier with the abutting end 21 that is inserted in housing 1 interior transmission terminal 2, then aforementioned ground wire 52 is done bending (seeing also accompanying drawing 1), to be positioned on the pressure contact portion 41 of connector 4 through the ground wire 52 of bending and the abutting end 31 of earth terminal 3 more at last, then connector 4 is done tight pressing, allow aforementioned ground wire 52, earth terminal 3 produce electrical the contact with connector 4 threes;

For preventing that aforementioned earth terminal 3 and connector 4 from producing the phenomenon that breaks away from, and please consults shown in accompanying drawing 3 and the accompanying drawing 4 again.As shown in the figure: wherein, this connector 6 also can directly extend the earth terminal 62 of predetermined quantity, and the other end has pressure connection terminal 61, and this pressure connection terminal 61 has the pressure contact portion 611 that is made for electric contact equally; Again, the both sides of this pressure contact portion 611 have the alar part 612 that voltage supply is closed.

By diagram as can be known, the utility model its same elder generation of 1 embodiment in addition combines signal transmission unit 51 with the abutting end 21 that is inserted in housing 1 interior transmission terminal 2, then aforementioned ground wire 52 is done bending (seeing also accompanying drawing 3), again the ground wire 52 through bending is positioned on the pressure contact portion 611 that is inserted in housing 1 interconnecting piece 6 at last, then the alar part 612 of connector 61 both sides is inwardly done tight pressing, allow aforementioned ground wire 52 electrically contact with connector 6 the two generation;

Wherein, this connector 6 is that one can to do electrical contact material made; Again, this pressure contact portion 611 can form the relief shape by the punching press program equally, produces better conducting contact effect thus.

Connector of the present utility model will contain the ground wire be located in the cable and earth terminal and do firm combine and these high frequency connectors have better electrical characteristic.

The ground structure of a kind of electric connector of the utility model, it is applicable to the connector of high-frequency transmission, and is mainly combined with some ground wires in the cable by a connection piece, allows high-frequency electric connecter lifting electrical characteristic when doing the signal transmission; And make ground wire and earth terminal remove the program of welding from, and shorten all manufacturing process and relevant cost.

In sum, the ground structure of the utility model electric connector can effectively improve the various shortcoming of traditional structure, makes it have more progressive, practicality person.
