`
`Electrical Connector
`
`(57)Abstract
`
`The present utility model relates to an electrical
`
`
`
`
`
`
`
`connector, wherein it comprises an insulating body and
`
`
`
`a plurality of first conductive terminals fixed in the
`
`
`
`insulating body, the insulating body is provided with a
`
`
`
`first inserting hole for inserting a docking connector,
`
`
`
`the first conductive tenninals are provided with a
`
`
`
`
`horizontal portion extending horizontally and a vertical
`
`
`
`
`portion extending vertically downward from the
`
`
`
`
`horizontal portion, the horizontal po,tion is provided
`
`
`
`with a contact portion extending into the first inserting
`
`
`
`hole, the horizontal portion is distributed in at least two
`
`
`rows along an up-to-down direction of the insulating
`
`body, and the insulating body is equipped with an
`
`
`insulating block at the upper end of each row of
`
`
`
`
`horizontal portions for resisting against the horizontal
`
`
`
`portion, so that the insulating block can prevent the first
`
`
`conductive tem1inals from moving upwardly, thereby
`
`
`
`preventing them from being deformed or causing signal
`crosstalk.

`
`with a horizontal tetminals are provided the first conductive connector, hole for inserting a docking
`
`
`
`
`
`
`
`
`portion extending horizontally and a vertical portion extending vertically downward from the
`
`
`
`
`
`
`
`
`horizontal portion, and the horizontal portion is provided with a contact portion extending into the
`
`
`
`
`
`first insetting hole, wherein the horizontal portion is distributed in at least two rows along an up-to­

`
`
`
`at the upper end of each row of horizontal portions for resisting against the horizontal portion.
`
`2.The electrical connector according to claim 1, wherein the insulating block is provided with
`
`
`
`
`
`
`
`
`
`
`
`
`a first portion parallel to the horizontal p01tion of the first conductive terminals to prevent the first

`insulating body.
`
`5.The electrical connector according to claim 2, wherein the insulating block is provided with
`
`
`
`
`
`
`
`
`
`a second portion located behind the vertical portion of the first conductive terminals and extending
`
`
`ve1tically downward from the rear end of the first portion.
`
`6.The electrical connector according to claim 5, wherein a buckle portion respectively extends
`

`7.The electrical connector according to claim I, wherein the insulating body is further provided
`
`
`
`
`
`
`
`
`
`
`
`
`
`with a second inserting hole under the first inserting hole, the electrical connector is provided with a
`
`
`
`
`
`
`second conductive terminal mounted in the second inserting hole, the second conductive te,minal is
`
`
`
`
`
`
`
`also provided with a horizontal portion extending horizontally along a front-to-back direction of the
`
`
`
`
`
`
`
`
`insulating body and a ve1tical portion extending vertically downward from the horizontal po1tion, and
`

`

`
`[BACKGROUND ART)
`
`With the development trend of the electronics industry, in order to fully reduce the area occupied
`
`
`
`
`
`
`
`
`
`
`
`by electrical connectors on circuit boards, a method by stackjng a plurality of electrical connectors
`
`
`
`
`
`on top of each other is often adopted in the industry. However, when the electrical connectors are
`
`
`
`
`
`
`stacked on top of each other, the conductive terminals of the electrical connectors on the upper layer
`
`
`
`
`
`
`must be lengthened. As a result, when the electrical connectors are assembled on the circuit boards,
`
`
`
`
`
`they can easily move upwardly under the upward resisting force from the circuit boards because the
`
`
`
`
`
`
`conductive terminal is too long, thereby causing deformation oftbe conductive terminals. 1n addition,
`
`
`
`
`
`
`unexpected collision can easily cause deformation of the upper layer of conductive terminals and
`
`cause installation troubles.
`
`For related prior art, please refer to an electrical connector disclosed in a Taiwan utility model
`
`
`
`
`
`
`
`
`
`
`
`patent with the publication No. of 573837 published on January wherein the electrical
`21, 2004,
`
`
`
`
`
`
`connector comprises an insulating body, a shielding shell assembled on the periphery of the insulating
`
`
`
`
`
`body, and a plurality of conductive terminals fixed on the insulating body; the insulating body is
`
`
`
`
`
`provided with a first insetting hole and a second inserting hole stacked one on top of the other, the
`
`
`
`
`
`
`
`
`conductive terminals comprise a first conductive tenninal installed in the first inserting hole and a
`
`
`
`
`
`
`second conductive terminal installed in the second inserting hole, each conductive terminal is
`
`
`
`
`
`
`
`
`provided with a horizontal portion extending horizontally and a vertical portion extending vertically
`
`
`
`
`
`
`
`downward from the horizontal portion, and the horizontal portion is provided with a contact po1tion
`
`
`
`
`
`
`
`extending into the inserting hole to connect a docking connector; and the horizontal portion of the
`
`
`
`
`fast conductive terminal is arranged in two rows along an up-to-down direction of the insulating body.
`
`
`
`Since the first conductive terminals are installed in the fast inserting hole on the upper layer of the
`
`
`
`
`
`
`insulating body, the length of the first conductive terminals is relatively long. 1n order to prevent the
`
`
`
`
`
`
`conductive termjnals from moving upwardly, the horizontal portions of the uppermost layer of
`
`
`
`
`
`
`
`conductive terminals of the electrical connector are provided with an insulating block installed on the
`
`
`
`
`insulating body, and the insulating block can prevent the uppermost layer of conductive terminals
`from moving upwardly.
`
`However, the horizontal portions of the first conductive terminals are arranged in two rows along
`
`
`
`
`
`
`
`
`
`
`the vertical direction of the iJ1Su.lating body, and the insulating block can only prevent the uppermost
`
`
`
`
`
`
`layer of h01izontal portions from moving upwardly. When the electrical connector is installed on a
`
`
`
`
`
`
`circuit board, the horizontal portions of the first conductive tenninals on the lower layer will
`
`
`
`
`
`
`inevitably move upwardly due to the resistance of the circuit board, which easily causes the
`
`
`
`
`
`defonnation of the first conductive tenninals on the lower layer. 1n addition, the upward movement
`
`
`
`
`
`
`of the first conductive terminals on the lower layer easily resists to the first conductive terminals on
`
`
`
`
`
`
`the upper layer, thereby causing signal crosstalk between the upper and lower rows of terminals.
