Description

High density electrical connector

The utility model relates to a kind of high density electrical connector, and it is smooth and easy, certain particularly to relate to a kind of butt joint, and the high density electrical connector that can increase the service life.

Continuous increase with personal computer function, hardware device also becomes thereupon and more simplifies, lightly, therefore the space in the computer chassis is occupied so that dwindle gradually, must hold than original more electronic component in the mode of stacked circuit plate, old friends are except that the function that keeps original electric connector, also develop a kind of high density electrical connector, so that transmit more substantial signal.And general high density electrical connector such as Fig. 9 A, shown in the 9B, it comprises first electric connector 90 and second electric connector 95, both are the high density electrical connector combination of butt joint, wherein the leading edge of first connector 90 is provided with the butt end of being made up of terminal groove seat 92 91, the leading edge of second connector 95 is provided with by terminal and puts the butt end 96 that plate 97 is formed, with terminal groove seat 92, terminal is put plate 97 and is supported several terminals, and the high density electrical connector of this kind structural design, because it is quite long that its terminal groove seat 92 and terminal are put plate 97, buckling deformation very easily appears, cause first, two high density

electrical connectors

90,95 at when butt joint easy-to-plug not, causes and uses inconvenience or electric connection insecure.Have again, this type of high density electrical connector is for solving static discharge (Electro-Static Discharges-ESD) problem that the human body contact is produced, put plate 97 front ends at terminal groove seat 92 and terminal and be provided with groove 921,971, and be embedded with conducting strip 93,98 (or electric wire, bus etc.), this conducting

strip

93,98 respectively with the metal part conducting of first and second high density

electrical connector

90,95 after ground connection.Its shortcoming is, is embedded difficulty because terminal groove seat 92, the terminal of strip are put the manufacturing of groove 921,971 of plate 97 and groove 921,971 and conducting strip 93,98 (line), improves whole manufacturing cost, and economic benefit is low.

The utility model purpose is the buckling deformation of avoiding the high density electrical connector butt end to be produced, makes the butt joint of high density electrical connector smooth and easy and electric connection is firm.

Another purpose of the present utility model is effectively to suppress the static discharge that the high density electrical connector butt end is produced.

The purpose of this utility model is achieved in that promptly provides a kind of high density electrical connector, and it comprises: an insulating body, which is provided with an interface, and the long limit horizontal line of this interface is provided with along the several terminals accepting groove of same long limit horizontal line vertical arrangement; Several terminals is located at the several terminals accepting groove of described insulating body.

The advantage of the utility model device is, by setting to several vertical terminal containing slots and dividing plate separation, make its high density electrical connector can not produce buckling deformation, and dock smooth and easy, connect firmly, the energy release electrostatic is because it is provided with accepting groove and accommodates plate, the butt end intensity of its connector is big, and increases the service life.
