[0075] Figure 4 is another perspective view of the first hybrid connector 10 according to the embodiments of the present invention.

[0076] Figure 5 is an exploded perspective view of the first hybrid connector 10 according to the embodiments of the present invention. Referring to Figures 3 to 5 , the components of the first hybrid connector 10 according to the embodiments of the present invention will be briefly described.

[0077] As Figures 3 to 5 shown, the first hybrid connector 10 includes an insulating housing 11, a plurality of signal contacts 12, a plurality of power contacts 13, and two pressing members 14. The signal contacts 12 and the power contacts 13 are both held by the insulating housing 11. The signal contacts 12 are arranged in two columns along a second direction D2 perpendicular to the first direction D1. The power contacts 13 are arranged along the second direction D2. Half of the power contacts 13 are disposed on one side of the signal contacts 12 in the second direction D2, and the other half of the power contacts 13 are disposed on the other side of the signal contacts 12 in the second direction D2. Each pressing member 14 is inserted into a holding groove 113 formed at an end of the insulating housing 11 in an interference fit manner. By welding the solder feet of the pressing member 14 to the pads of the circuit board, the first hybrid connector 10 can be firmly fixed to the circuit board.

[0078] The insulating housing 11 includes a signal fitting portion 111, three power fitting portions 112 located on one side of the signal fitting portion 111, and three power fitting portions 112 located on the other side of the signal fitting portion 111. The signal contacts 12 (especially the contact arms of the signal contacts 12) are disposed in the signal fitting portion 111. As Figure 5 shown, every two power contacts 13 are paired and thus constitute a pair of power contacts 13P as a two-piece power contact. Each power fitting portion 112 houses its respective pair of power contacts 13P (i.e., two paired power contacts 13).

[0079] Figure 6 is a perspective view of the insulating housing 11 of the first hybrid connector 10 according to an embodiment of the present invention. A plurality of recesses 114 are formed on the outer surface of the side wall of the insulating housing 11 adjacent to the signal fitting portion 111. The recesses 114 are used to engage with the gripping claws of a cover member (shown in Figure 10 ). The side wall of the insulating housing 11 adjacent to the signal fitting portion 111 has one or more void portions 115. For the convenience of forming, the void portions 115 open to the bottom surface of the insulating housing 11. By forming the void portions 115, deformation caused by uneven shrinkage can be prevented.

[0080] As can be seen in Figure 6 , positioning posts 116 are formed on the bottom surface of the insulating housing 11. Before welding the first hybrid connector 10 to the circuit board using surface mount technology, the positioning posts 116 can be used to temporarily position the first hybrid connector 10 in place.

[0082] The signal contact 12 includes a connection terminal portion 121, a holding portion 122, an extension portion 123, a contact arm 124, and a contact portion 125. The connection terminal portion 121 extends in a third direction D3 that is perpendicular to the first direction D1 and the second direction D2. The connection terminal portion 121 is soldered to a pad formed on the first circuit board P1 by surface mount technology (SMT). When the first hybrid connector is mounted on the first circuit board P1, at least a portion of the connection terminal portion 121 of the signal contact 12 is exposed from the insulating housing 11 so as to inspect the soldering state of the connection terminal portion 121. The holding portion 122 extends from the connection terminal portion 121 in the first direction D1. The holding portion 122 has a barb structure and is inserted into a signal contact holding hole formed in the insulating housing 11 in an interference fit manner. The extension portion 123 extends from the holding portion 122 in the first direction D1. The contact arm 124 is inclined with respect to the extension portion 123 and extends into the signal fitting portion. The contact portion 125 is formed at the distal end of the contact arm 124 and is configured to be V-shaped or L-shaped.
