Description

Electric connector

Technical field

The utility model relates to a kind of electric connector, the technical field that belongs to data transmission structure between the electronic information technology product, belong to data signals transmission between the electronic information technology product, the particularly technical field of the connector of external memory hard disk and host data signal transmission specifically.

Especially refer in the socket of pedestal, be formed with the communal space between unsettled set the first terminal seat, second terminal base, and on socket two side wall surfaces in the first terminal seat two outsides, placed power supply terminal respectively, after inserting for the eSATA connector, required power supply when transmission signal is provided.

Background technology

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 transmission line usually so that transmission signal each other, and at present signal transmission line and electronic installation dock with connector body on the electronic installation through transmission line one terminal adapter mostly, moreover, the most universal signal transmission standard of computer equipment is no more than universal serial bus (Universal Serial Bus now, USB), advanced supplementary technology (the External Serial ATA of sequence, transmission standard such as eSATA), can use on the present jumbo external hard drive with connector body and transmission line that this specification is made, and with the computer plug and play, need not to wait for that computer starts shooting again, then there is the dealer to develop overlapping waded electric connector, with universal serial bus (USB), the advanced supplementary technology of sequence (eSATA) is integrated in the connector, and has two kinds of different transmission standards simultaneously; Yet, along with the design of electronic product towards light, when thin, short, little target strides forward, 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.

The improvement design of dealer at overlapping waded electric connector then arranged, see also shown in Figure 8, mainly lie in the terminal base upper surface and be provided with the eSATA terminal group, and the terminal base lower surface is provided with the USB terminal group, eSATA terminal group and two kinds of different sizes combinations of USB terminal group are arranged on the same terminal base, can and form for outside default USB connector, the plant of eSATA connector and electrically connect, this kind method is not only significantly reduced the excessive problem of overlapping waded electric connector volume, also meets light, thin, short, the little design object of computer product.

But, because above-mentioned connector improvement, when the user desires to make outside eSATA connector to be inserted in terminal base, can form with the eSATA terminal group of terminal base upper surface and electrically connect, moreover, when the external USB connector 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 insert to form and electrically connect, in the process of planting, then can cause the inconvenience of manipulating and when planting not smoothly, and this kind commonly use connector with the terminal group of two kinds of specifications in conjunction with being arranged on the same terminal base, do not design any anti-misoperation device, when planting, do not note the kenel that is provided with of terminal group easily because of the user, with the external USB connector, the eSATA connector misplugs or instead inserts and causes damage.

When butting up against the eSATA terminal group formation electric connection of terminal base upper surface because of the default eSATA connector in the outside of commonly using connector again, the set USB terminal group of side can be subjected to the friction of outside eSATA connector in addition, during with respect to default USB connector 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 connector in addition, repeatedly plug under the use for a long time in USB connector and eSATA connector, can make the USB terminal group, eSATA terminal group excessive wear and cause the terminal elastic fatigue, and then cause shorten whole useful life.

Moreover general eSATA connector must also cause eSATA connector many disappearances in use in addition with the required power supply of power connector supply eSATA connector in use, as:

(1) present employed eSATA connector all needs additionally to set up power connector, then must peg graft simultaneously during use and just can transmit data, otherwise promptly can't transmit data, and is quite inconvenient during use.

(2) the eSATA connector is arranged on the circuit board, promptly power connector must be set again, also can take the space on the circuit board, influences the circuit layout of circuit board.

How to solve the eSATA connector of commonly using in the overlapping waded electric connector, the problem and the disappearance of power connector must be set in use in addition, be the direction place of the improvement that relevant manufacturer is studied of being engaged in the industry.

Summary of the invention

The utility model provides a kind of electric connector, is intended to solve the deficiencies in the prior art, realizes not needing additionally to set up power connector, saves the circuit board space position, does not influence circuit layout, conformance with standard and use more convenient purpose.
