The present invention provides a hybrid plug connector, which comprises a plug housing, a row of signal terminal assemblies and a row of power terminals. The plug housing includes a signal plug part and a power plug part adjacent to the signal plug part. The signal plug part has a signal port formed on the front thereof, and a row of signal terminal-receiving passages formed on the rear thereof and communicated with the signal port. The power plug part has a row of power terminal-receiving passages passing through the front and rear thereof. Each power terminal-receiving passage has a pair of crossbeams formed on a left wall and a right wall of the power terminal-receiving passage and separated each other. Each of the signal terminal assemblies includes an insulative frame, multiple signal contact arms extending out of the front of the insulative frame, and multiple signal tails extending out of the bottom of the insulative frame. The insulative frame is mounted in the corresponding signal terminal-receiving passage. The signal contact arms enter into the signal port. The signal tails extend out of the bottom of the signal plug part. Each of the power terminals includes two independent and symmetrical conductive plates. The two conductive plates are combined together. Each conductive plate has a vertical plate, a mating portion located in front of the vertical plate, a tilted connection portion formed by being bent outward from a bottom edge of the vertical plate, and multiple power tails located under the connection portion. The conductive plate further has a first protrusion and a second protrusion located below the first protrusion. When the power terminal is mounted in the power plug part, the mating portions of the two conductive plate extend out of the front of the power plug part, the vertical plates thereof are clamped by the pair of crossbeams, the first protrusion and the second protrusion together clamp the corresponding crossbeam along a vertical direction, and the tails thereof extend out of the bottom of the power plug part.
In one embodiment, a vertical distance between the first protrusion and the second protrusion is equal to a height of the crossbeam; the first protrusion is formed on one side of the vertical plate; the second protrusion is formed on the connection portion; and the pair of crossbeams are symmetrical to each other and extend along a front and rear direction.
In one embodiment, the first protrusion is a closed circular are profile; the second protrusion is upright and has a free end; the crossbeam is clamped by the bottom of the first protrusion and the free end of the second protrusion; and the conductive plate has two second protrusions on the connection portion.
In one embodiment, the mating portion of the conductive plate is blade-like and located on a same vertical plane with the vertical plate.
In one embodiment, the power plug part further has a long slot, which is formed on the top of the power plug part and is communicated with the power terminal-receiving passages, and an anti-mistake recess formed on one sidewall of the long slot; and
the vertical plate has an opening formed on a top edge thereof and a hook located on a sidewall of the opening;
when the power terminal is mounted in the power plug part, the opening is aligned with the long slot.
In one embodiment, the hybrid plug connector further comprises at least one tie bar, which includes an anti-mistake bump located on the front of the tie bar and multiple locks located on the rear of the tie bar, the tie bar is embedded into the long slot of the power plug part and enters into the openings of the power terminals; wherein the anti-mistake bump is engaged with the anti-mistake recess, and these locks are engaged with the hooks of the power terminals.
In one embodiment, the hybrid plug connector further comprises two guiding posts, which are symmetrically disposed on the top of the plug housing, and each of which has a column body with a cross-shaped section and a tip end.
In one embodiment, the signal plug part further includes a row of retaining holes formed on the top thereof and communicated with the corresponding signal terminal-receiving passages; the insulative frame has a cut formed on the top thereof and a cantilever beam located in the cut and extending backward from a front wall of the cut; the cantilever beam forms a protrusion protruding upward on the end thereof; the cut of the insulative frame is aligned with the corresponding retaining hole of the signal plug part, and the cantilever beam and the protrusion enter into the corresponding retaining hole.
In one embodiment, the plug housing has two power plug parts located two sides of the signal plug part respectively; a front surface of the signal plug part is located in front of a front surface of each power plug part; and the row of signal terminal assemblies is located in the middle of the row of power terminals.
In one embodiment, the plug housing is further provided with multiple narrow holes on the top thereof and these narrow holes are communicated with some power terminal-receiving passages for dissipating the heat.
In comparison with the prior art, the hybrid plug connector of the present invention can make power supply and signal transmission functions be integrated together for ensuring integrity of the power supply and the signal transmission. The hybrid plug connector of the present invention further improves a strong structural stability and safety thereof by modifying the power terminals. Moreover, the hybrid plug connector of the present invention further can be connected with an external receptacle connector safely and accurately by modifying the guiding posts.
