As illustrated in
Each of the ground contacts 230 may further include a shell contact portion 231 b that contacts the shell 240. The shell contact portion 231b may contact the upper plate 244. For example, as illustrated in
The projecting portions 244b are spaced apart from one another and aligned with the arrangement direction AD2. The projecting portions 244b correspond to the ground contacts 230, respectively. Each of the projecting portions 244b projects rearward from the base portion 244a so as to sandwich the first partition portion 231 of the corresponding ground contact 230 with the circuit board CB.
In each of the ground contacts 230, the shell contact portion 231b is formed in the first partition portion 231 to contact a corresponding projecting portion 244b. For example, the shell contact portion 231b is formed at the upper edge of the first partition portion 231 to slightly displace the corresponding projecting portion 244b upward relative to the base portion 244a. The contact state between the shell contact portion 231b and the projecting portion 244b is maintained by the repulsive force against the elastic deformation of the projecting portion 244b.

As described above, the receptacle connector 200 includes: the insulating housing 210 having the lower surface 211 facing the circuit board CB; and a plurality of conductive contacts RC held in the insulating housing 210 so as to align in the arrangement direction AD2 parallel to the lower surface 211, in which the contacts RC include: the first signal contact 220 including the first connection portion 221 connected to the first signal conductor BS of the circuit board CB and the first contact portion 222 contacting the signal contact 120 (the first mate signal contact) of the plug connector 100 (the mate connector); the second signal contact 220 including the second connection portion 221 connected to the second signal conductor BS of the circuit board CB and the second contact portion 222 contacting the signal contact 120 (the second mate signal contact) of the plug connector 100; and the ground contact 230 including the ground connection portion 231a connected to the ground conductor BG of the circuit board CB and the ground contact portion 232b contacting the ground contact 130 (the mate ground contact) of the plug connector 100. The ground contact 230 is located between the first signal contact 220 and the second signal contact 220 and extends along the plane OP perpendicular to the arrangement direction AD2 so as to form the partition wall PW between the region including the first signal contact 220 and the region including the second signal contact 220.
According to the present the receptacle connector 200, by utilizing the ground contact 230 itself as a partition wall, more partition walls PW can readily be arranged between the signal contacts 220. Therefore, crosstalk may further be reduced by the receptacle connector 200.
The first connection portion 221 and the second connection portion 221 may be located outside the insulating housing 210 when viewed from a direction perpendicular to the lower surface 211. The ground contact 230 may include: the first partition portion 231 located between the first connection portion 221 and the second connection portion 221 outside the insulating housing 210 and extending along the plane OP perpendicular to the arrangement direction AD2; and the second partition portion 232 projecting from the first partition portion 231 into the insulating housing 210 to be located between the first contact portion 222 and the second contact portion 222 and extending along the plane OP perpendicular to the arrangement direction AD2. The ground connection portion 231a may be fortified in the first partition portion 231, and the ground contact portion 232b may be formed in the second partition portion 232. For example, the partition wall PW can readily be formed both outside the insulating housing 210 and inside the insulating housing 210. Therefore, the crosstalk may further be reduced.
The width of the first partition portion 231 in a direction perpendicular to the lower surface 211 may be greater than the width of the second partition portion 232 in a direction perpendicular to the lower surface 211. For example, the crosstalk can be further reduced by increasing the areas of the partition wall PW outside the insulating housing 210.
The receptacle connector 200 may further include an electrically conductive the shell 240 housing the insulating housing 210, and the ground contact 230 may further include the shell contact portion 231b contacting the shell 240.

The receptacle connector 200 may include a plurality of ground contacts 230. Each of the ground contacts 230 may include the first partition portion 231 and the second partition portion 232. The upper plate 244 may include a plurality of the projecting portion 244b. Each of the projecting portions 244b may project from the base portion 244a so as to sandwich the first partition portion 231 of the ground contact 230 with the circuit board CB. The shell contact portion 231b of each of the ground contacts 230 may contact a corresponding projecting portion 244b. Each of the ground contacts 230 may contact more firmly with the upper plate 244 by forming the projecting portion 244b for each of the ground contacts 230.
The ground contact 230 may further include the third partition portion 233 projecting from the first partition portion 231 into the insulating housing 210 and located between the second partition portion 232 and the circuit board CB. The insulating housing 210 may include the regulating portion 217 located between the second partition portion 232 and the third partition portion 233 to regulate displacement of the ground contact 230. Both the reliability of holding the ground contact 230 and the expansion of the partition wall PW in the insulating housing 210 may be achieved.
The width W1 of the first partition portion 231 in the direction perpendicular to the lower surface 211 may be greater than the sum of the width W2 of the second partition portion 232 in the direction perpendicular to the lower surface 211 and a width W3 of the third partition portion 233 in the direction perpendicular to the lower surface 211. The crosstalk may further be reduced by further increasing the areas of the partition wall PW outside the insulating housing 210.
The plug connector 100 may further include: the insulating housing 110 (the mate insulating housing) holding the signal contact 120 (the first mate signal contact), the signal contact 120 (the second mate signal contact), and the ground contact 130 (the mate ground contact); and the conductive shell 140 (the mate shell). The third partition portion 233 may be formed with the mate shell contact portion 233b contacting the shell 140. The crosstalk may further be reduced by further stabilizing the potential of the third partition portion 233 branched from the second partition portion 232.
The ground contact 130 may be located between the second partition portion 232 and the third partition portion 233. The shell 140 may include the lower plate 146 (lower mate plate) located between the ground contact 130 and the third partition portion 233.

The mate shell contact portion 233b may be formed on a portion of the third partition portion 233 facing the second partition portion 232. The space between the second partition portion 232 and the third partition portion 233 can be effectively utilized as a space for placing the ground contact 130 and the lower plate 146 may be placed in the space between the second partition portion 232 and the third partition portion 233, to reduce the height of the receptacle connector 200.
The shell 240 of the receptacle connector 200 may further include the lower plate 243 located between the lower plate 146 and the circuit board CB and contacting the lower plate 146. The lower plate 243 may be formed with the slit 243c to house the third partition portion 233. Since the mate shell contact portion 233b is connected to the lower plate 243 via the lower plate 146, the potential of the ground contact 230 is further stabilized. In addition, the height of the receptacle connector 200 can be reduced by arranging the third partition portion 233 on the slit 243c. Therefore, both further reduction of the crosstalk and reduction in height of the receptacle connector 200 may be reduced.
The ground contact 230 may further include the third partition portion 233 projecting from the first partition portion 231 into the insulating housing 210 and located between the second partition portion 232 and the circuit board CB.

The ground contact portion 232b may be formed on a portion of the floating portion 232a facing the third partition portion 233 in the second partition portion 232. The third partition portion 233 may include the floating portion 233a spaced apart from the circuit board CB and the mate shell contact portion 233b contacting the shell 140. The mate shell contact portion 233b may be formed at a portion facing the second partition portion 232 in the floating portion 233a of the third partition portion 233 and contact the lower plate 146. The ground contact portion 232b may contact more firmly with the ground contact 130 by the elasticity of the second partition portion 232. In addition, the elasticity of the third partition portion 233 can be used to bring the mate shell contact portion 233b into more firm contact with the shell 140. Therefore, the potential of the ground contact 230 can be further stabilized. The shell 240 may further include the rear plate 245 (the shell wall) facing the insulating housing 210 across the rear external space OS where the first connection portion 221, the second connection portion 221, and the first partition portion 231 are located.
