Abstract

A socket connector includes an insulating body having a base body and a holding body extending upward from a front of the base body. The holding body defines a terminal fillister spread to the base body. A plurality of openings is opened in a front face of the holding body and communicates with the terminal fillister. A terminal group molding in the terminal fillister of the insulating body has a plurality of elastic touching arms stretching outside the insulating body, and a plurality of contact slices exposed through the openings respectively. A magnetic body defines a window. The magnetic body is mounted to a front of the insulating body with the window facing the openings to further expose the contact slices therethrough. The terminal group has a ground terminal elastically projecting forward out of the insulating body to electrically abut against a rear face of the magnetic body.

Claims

1. A socket connector, comprising:

an insulating body having a base body and a holding body extending upward from a front of the base body, the holding body defining a terminal fillister spread to the base body, a plurality of openings being opened in a front face of the holding body and communicating with the terminal fillister;

a terminal group molding in the terminal fillister of the insulating body, the terminal group having a plurality of elastic touching arms stretching outside the insulating body, and a plurality of contact slices exposed through the openings respectively; and

a magnetic body defining a window, the magnetic body being mounted to a front of the insulating body with the window facing the openings to further expose the contact slices therethrough, the terminal group having a ground terminal elastically projecting forward out of the insulating body to electrically abut against a rear face of the magnetic body;

wherein two sides of the front of the insulating body define a pair of L-shaped receiving grooves of which each includes a first receiving groove vertically opened in the holding body and a second receiving groove horizontally opened in the base body and penetrating through a bottom of the base body, the second receiving groove has one inner end thereof connected with a bottom of the first receiving groove, a pair of L-shaped holding portions protrudes forward at two outmost sides of the first receiving grooves, and each extends vertically over the second receiving groove to define a holding channel between the holding portion and a rear inside of the first receiving groove, the magnetic body has a base board covered on a front face of the holding body and a front side of the base body with the window opened in a substantial middle thereof, two opposite sides of the base board extend rearward to form two side walls disposed in the first receiving grooves, rears of two opposite outer sides of the side walls oppositely protrude sideward to form a pair of holding latches each extending vertically at an upper portion thereof to be held in the corresponding holding channel, and a pair of holding ears at bottoms thereof secured in the second receiving grooves, the ground terminal elastically projects forward in one first receiving groove to abut against the rear face of the corresponding side wall of the magnetic body.

2. The socket connector as claimed in claim 1, wherein a pair of holding blocks protrudes forward at two outmost ends of the second receiving grooves, an inner side of each holding block protrudes inward to form a holding rib of a substantial semi-cylinder shape extending along a front-to-rear direction, a free end of each holding ear has a top corner cut off to define a guiding slope slantwise and smoothly connecting a top side and a bottom side of the holding ear, the magnetic body is assembled to the front of the insulating body by means of pushing the magnetic body upward under the cooperation and guidance between the side walls and the first receiving grooves and between the holding latches and the holding channels, the holding ears slide upward over the holding ribs by virtue of the guidance of the guiding slopes to be held by the holding ribs in the second receiving grooves.

3. The socket connector as claimed in claim 2, wherein an upper portion of the rear inside of the one first receiving groove protrudes forward to form a blocking block apart from the holding portion, the rear face of the corresponding side wall defines a receiving gap opened at a top thereof, and a receiving channel extending vertically to penetrate through a bottom thereof, a blocking rib is formed under the receiving gap and extends vertically adjacent to the receiving channel, the blocking rib resists against a bottom of the blocking block when the blocking block is positioned in the receiving gap, the ground terminal is pressed in the receiving channel.

4. The socket connector as claimed in claim 1, wherein the terminal group further includes a power terminal having the contact slice extending downward from one end of a bottom edge of a base strip, and the elastic touching arm bending rearward and inclining upward from a bottom end of the contact slice, the ground terminal extends downward from the other end of the bottom edge of the base strip and is inclined forward in process of extending downward, the terminal group further includes a signal terminal independent of the ground terminal and the power terminal, the signal terminal has a structure similar to that of the power terminal, and has the contact slice and the elastic touching arm, the base strip and the contact slices are embedded in the terminal fillister of the insulating body with the signal terminal located between the ground terminal and the power terminal, the elastic touching arms project beyond a top side of the base body and behind the holding body.

5. The socket connector as claimed in claim 4, wherein the terminal fillister includes an inserting slot opened in a top of the holding body for clipping the base strip of the terminal group therein, a plurality of fastening slots apart concaved downward from a bottom side of the inserting slot and correspondingly opened behind the openings to further connect with the corresponding openings for inserting the contact slices therein, and a plurality of receiving passages opened in a rear of the base body and each extending along a front-to-rear direction to connect with a bottom of the corresponding fastening slot, the receiving passages further penetrate through the top side of the base body, the elastic touching arms project upward out of the receiving passages.

6. The socket connector as claimed in claim 4, wherein the terminal group further includes a fixing terminal of a rectangular slice shape extending downward from the bottom edge of the base strip, the fixing terminal is embedded in the terminal fillister of the insulating body and located between the ground terminal and the contact slice of the signal terminal, the fixing terminal is further exposed through one of the openings of the holding body and the window of the magnetic body.
