Description

Electric connector

Technical field

The utility model relates to electric connector, refers to a kind of electric connector for USB interface plug or the grafting of eSATA interface plug especially.

Background technology

Press, electronics technology fast lifting in the society now, and apply on the computer in a large number, and it is closely bound up with people's life, between different electronic installations, also link to each other with signal transmssion line usually so that transmission signals each other, and at present signal transmssion line and electronic installation dock with connector body on the electronic installation by transmission line one end connector mostly, moreover, the most universal signal transmission standard of computer equipment is no more than USB (Universal Serial Bus now, USB), external series ATA transmission standards such as (External Serial AdvancedTechnology Attachment), can use on the present jumbo external hard drive with connector body and transmission line that this standard is made, and with the computer plug and play, need not wait for that computer starts shooting again, then there is the dealer to develop overlapping waded electric connector, with USB (USB), (eSATA) be integrated in the connector, and have two kinds of different transmission standards simultaneously, see also shown in Figure 8, it is the stereo appearance figure of prior art, find out by knowing among the figure, this pedestal A is respectively equipped with two jack A1, A2, and in two jack A1, be respectively equipped with in the A2 and meet the external USB plug, the terminal base B of eSATA plug standards, C, and in terminal base B, be respectively equipped with corresponding terminal B1 on the C, C1, when USB plug or eSATA plug butt up against jack A1, during A2, can be respectively and terminal base B, terminal B1 on the C, C1 forms electric connection; Yet, along with the design of electronic product strides forward towards light, thin, short, little target, when above-mentioned overlapping waded electric connector is installed in circuit board top in the electronic product, can cause the excessive problem of volume, and taken most locus on the circuit board, and can't meet light, thin, short, the little design requirement of electronic product.

So, improvement design at overlapping waded electric connector is just arranged, mainly be that the single terminal base of usefulness is used as USB plug or the butt joint of eSATA plug, be to be provided with the eSATA terminal group at the terminal base upper surface, and the terminal base lower surface is provided with the USB terminal group, eSATA terminal group and two kinds of various criterions combinations of USB terminal group are arranged on the same terminal base, can be for outside default USB plug, the eSATA plug is planted and is formed and electrically connects, this kind method is not only significantly reduced the excessive problem of overlapping waded electric connector volume, and it is light also to meet computer product, thin, short, little design object.

But, because above-mentioned connector improvement, when the user desires to make outside eSATA plug to be inserted in terminal base, can form electric connection with the eSATA terminal group of terminal base upper surface, moreover, when the external USB plug is inserted in same terminal base, the USB terminal group pattern of necessary abutting end stroma lower surface earlier with after the USB plug counter-rotating, just can be inserted and form electric connection, in the process of planting, then can cause the inconvenience of manipulating and when planting not smoothly.

And this kind prior art connector is arranged at eSATA terminal group and two kinds of standards combinations of USB terminal group on the same terminal base, do not design any anti-misoperation device, when planting, do not note easily the kenel that is provided with of terminal group, external USB plug, eSATA plug are mispluged or instead insert and cause damage because of the user.

Again, because the default eSATA plug in the outside of prior art connector butts up against the eSATA terminal group of terminal base upper surface and forms when electrically connecting, the set USB terminal group of side can be subjected to the friction of outside eSATA plug in addition, during with respect to default USB plug in outside and USB terminal group formation electric connection, the set eSATA terminal group of side also can be subjected to the friction of outside default USB plug in addition, repeatedly plug under the use for a long time in USB plug and eSATA plug, can make the USB terminal group, eSATA terminal group excessive wear and cause the terminal elastic fatigue, and then cause shorten whole useful life.

Be with, how to solve the problem and the shortcoming of prior art connector improvement, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.

Summary of the invention

So the inventor is to collect related data because above-mentioned problem and shortcoming, via assessing in many ways and consider, and to engage in the many years of experience of the industry accumulation, via constantly studying and revising, the beginning is designed the utility model of this kind electric connector.

The utility model provides a kind of electric connector, includes pedestal, the first terminal group, second terminal group and shield shell, and pedestal is for uprightly being arranged on the preinstalled circuit plate; Wherein:

This pedestal one side offers the socket that can supply default plug to insert, and socket interior sidewall surface upright respectively unsettled have the first terminal seat, second terminal base, is formed with a shared space between the first terminal seat and second terminal base;

This first terminal group is for meeting USB (USB, Universal Serial Bus) interface standard, and the first terminal group is provided with the contact site that is positioned at the first terminal seat, and is provided with the turning point and is extended with contact site at the turning point end in contact site one side and be vertical connecting portion;

This second terminal group is for meeting eSATA (external series ATA, External Serial ATA) interface standard, and second terminal group is provided with the contact site that is positioned at second terminal base, and is provided with the turning point and is extended with contact site at the turning point end in contact site one side and be vertical connecting portion;

This shield shell is coated on the pedestal outer rim, and shield shell is provided with the opening that communicates with the pedestal socket.

Above-mentioned electric connector of the present utility model has following advantage when reality is used, as:

Main purpose of the present utility model is to be to be provided with in the socket of pedestal to be the unsettled upright the first terminal seat and second terminal base, and between the two-terminal seat, be formed with sharing space, after USB interface plug or the insertion of eSATA interface plug, can prevent the terminal frictional dissipation on the abutting end stroma, and the overall volume of dwindling pedestal simultaneously.

Secondary objective of the present utility model is to be wherein to be bent with fool proof portion under left and right two side direction of a terminal base in the socket of pedestal; can prevent that with this USB interface plug from mispluging or the eSATA interface plug is instead inserted, and the protection terminal group can be because of not mispluging or instead inserting and cause friction to damage.
