DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1, 2, 3 and 4A to 4E show a first embodiment of a plug connector 10 for balanced transmission. Arrows X1, X2 show opposite directions parallel to longitudinal sides of a front face of the connector 10. An arrow Y1 shows a direction perpendicular to and into the plane of the front face of the connector 10. An arrow Y2 shows a direction perpendicular to and out of the plane of the front face of the connector 10. Arrows Z1, Z2 show opposite directions parallel to lateral sides of a front face of the connector 10, the arrow Z1 showing an upward direction and the arrow Z2 showing a downward direction.
The first right-angled plug signal contact 11-1 and the second right-angled plug signal contact 11-2 are adjacent to each other in a Y-Z plane so as to form a pair of right-angled plug signal contacts 11-1, 11-2. The plurality of pairs of first and second right-angled plug signal contacts 11-1, 11-2 and the right-angled plug ground contacts 12 are alternately disposed in the X1-X2 directions with a pitch p=0.635 mm. The characteristic impedance of the first and second right-angled plug signal contacts 11-1, 11-2 is 50 Ω. Thus, the plug connector 10 is suitable for use in balanced transmission.
Secondly, the upper bracket 40 and the lower bracket 50 are assembled to the housing 31. The upper-bracket 40 will be described with reference to FIGS. 5, 10 and 11. The upper bracket 40 is made of liquid crystal polymer and has an electrically insulating characteristic. The upper bracket 40 is provided with a plurality of upper-bracket signal contact grooves 41 extending in Y1-Y2 directions and corresponding to the horizontal parts 11-1 b of the first right-angled plug signal contacts 11-1, a plurality of upper-bracket ground contact grooves 42 extending in Y1-Y2 directions and corresponding to the upper half parts 12 a 1 of the extensions 12 a, and rails 43, 44 provided at either one of X1, X2 ends. The upper-bracket signal contact grooves 41 and the upper-bracket ground contact grooves 42 are alternately arranged. Partition walls 45 are provided between the upper-bracket signal contact grooves 41 and the upper-bracket ground contact grooves 42. The upper-bracket signal contact grooves 41 and the upper-bracket ground contact grooves 42 terminate at the Y2 end of the upper bracket 40.
As shown in FIGS. 6, 8 and 9, the upper-bracket signal contact groove 41 is fitted with the horizontal part 11-1 b of the first right-angled plug signal contact 11-1. That is to say, the upper-bracket signal contact groove 41 substantially covers the upper surface and both side surfaces of the horizontal part 11-1 b of the first right-angled plug signal contact 11-1. As shown in FIGS. 7, 8, and 9, the upper-bracket ground contact groove 42 covers the upper half part 12 a of the extension 12 a of the ground contact 12.
Again referring to FIG. 10, the lower bracket 50 is slid into the housing 31 in the direction shown by an arrow B with the holes 57, 58, 59 and 60 fitted with the vertical parts 11-1 c, 11-2 c of the first and second right-angled plug signal contacts 11-1, 11-2 and the ground terminals 12 b, 12 c, respectively. As shown in FIGS. 8 and 9, the rails 53, 54 are tightly fitted between the arms 32, 33 until the rails 53, 54 abut the raised guide parts 36, 37. Thus, the lower bracket 50 is fitted such that its upper surface abuts the lower surface of the upper bracket 40.
As shown in FIGS. 6, 8 and 9, the lower-bracket signal contact groove 51 is fitted with the horizontal part 11-2 b of the second right-angled plug signal contact 11-2. That is to say, the lower-bracket signal contact groove 51 substantially covers the upper surface and both side surfaces of the horizontal part 11-2 b of the second signal right-angled plug signal contact 11-2. As shown in FIGS. 7, 8, and 9, the lower-bracket signal contact groove 52 covers the lower half part 12 a 2 of the extension 12 a of the ground contact 12. The length adjusting part 11-2 d is accommodated in a pit 56. Also, the vertical parts 11-1 c, 11-2 c of the first and second right-angled plug signal contacts 11-1, 11-2 and the ground terminals 12 b, 12 c penetrate the holes 57, 58, 59 and 60, respectively, and protrudes from the lower surface of the lower bracket 50 in the direction Z2.
In FIG. 6, it may be seen that the top part of the vertical part 11-1 c of the first right-angled plug signal contact 11-1 traverses the synthetic resin injection channel 63 in the Z1-Z2 directions. However, as shown in FIG. 11, a width W1 of the synthetic resin injection groove 61 (or of the synthetic resin injection channel 63) is larger than a width W2 of the vertical part 11-1 c of the first right-angled plug signal contact 11-1. Thus, a gap 64 is formed on both sides of the vertical part 11-c of the first right-angled plug signal contact 11-1. Therefore, the epoxy resin is injected through injection channels also at positions where the vertical parts 11-1 c are provided.
Finally, the plug connector 10 is provided with an external shield. Referring to FIG. 6, the front half part 81 a-1 of the horizontal shield plate part 81 a and the shield plate part 71 inserted in the housing 31 shield the portions of the first and second right-angled plug signal contacts 11-1, 11-2, which portions do not extend out at the backside of the housing 31. Also, the horizontal shielding plate part 81 a and the vertical shielding plate part 81 b of the upper shielding member 80 shield the substantially right-angled first and second contact portions 11-1 a and 11-2 a. Therefore, it is possible to effectively reduce the possibility that the positive signals (+) and the negative signals (−) transmitted through the first and second right-angled plug signal contacts 11-1, 11-2 in a balanced manner are affected by external electromagnetic waves.
