Two strands, two binding posts 12 are electrically connected.
In a specific embodiment, as shown in Figure 1, Figure 2 and shown in Fig. 3, terminal 83 and the binding post 12 of the first connector 8 connect
Touching, so that internal circuit communication；Clutch male seat 23 is inserted into clutch base 16 at this time, so that active rotating shaft 2 can not rotate,
The first connector 8 can be inserted into external interface at this time, since clutch is in closed state, even if the first connector 8 receives external force
It can not still retract inside shell 1；
When needing to change the operating position of the first connector 8 or the second connector 9, as shown in Figures 5 and 6, pulls out and actively turn
Axis 2, clutch male seat 23 are separated with clutch base 16, can be rotated active rotating shaft 2 at this time with 90 degree of integral multiple, be changed the position of connector
It sets；
When initial position, the first connector 8 stretches out, and the second connector 9 retracts；
After being rotated by 90 ° counterclockwise, the first connector 8 is retracted, and the second connector 9 retracts；
Continue after being rotated by 90 ° counterclockwise, the first connector 8 retracts, and the second connector 9 stretches out；
Continue after being rotated by 90 ° counterclockwise, the first connector 8 retracts, and the second connector 9 retracts；
Continue after being rotated by 90 ° counterclockwise, returns to initial position.
Further, first connector 8 is HDMI Type-A connector, and second connector 9 is that HDMI Type-B connects
Head or HDMI Type-C connector.
More commonly used is HDMI Type-A connector on the market, in addition it is more commonly used be HDMI Type-B connector or
HDMI Type-C connector；So the first connector 8 of setting is HDMI Type-A connector, the second connector 9 is HDMI Type-B connector
Or HDMI Type-C connector.
Further, the outer surface of the shell 1 is coated with insulating film.
To prevent from leaking electricity when in use in HDMI connector, insulating film is coated in the outer surface of shell 1.
Further, bearing 151 is also equipped between the active rotating shaft 2 and the rotation shaft opening 15.
Bearing 151 is set between active rotating shaft 2 and rotation shaft opening 15, so that the rotation of active rotating shaft 2 is more stable.
Further, raised 22 length is greater than the length of the groove 31.
Since active rotating shaft 2 needs to pull out, the length of the length butterfish groove 31 of setting protrusion 22, so that working as active rotating shaft
2 pull out one end apart from when, the contact surface of groove 31 can touch protrusion 22.
Further, the latch 231 is obliquely installed, and the latch 231 is from root to top inclination at an acute angle.
Latch 231 is obliquely installed when being inserted into clutch base 16 and enables to insertion that can be easier by clutch work 23
Ground carries out.
Further, the inclined angle of the latch 231 is 1 ° -5 °.
In order to which latch 231 can be easy insertion tooth socket 161, and active turn can be effectively limited after guaranteeing clutch closure
The rotation of axis 2, the setting inclined angle of latch 231 are 1 ° -5 °.
Further, the section of the upper half of the binding post 12 is trapezoidal, and the section of 83 lower half of terminal is ladder
Shape.
In order to enable can increase as far as possible contact area when terminal 83 and binding post 12 cooperate, guarantee electrically transmission
Stability, be by the section of the upper half of the binding post 12 it is trapezoidal, the section of 83 lower half of terminal is trapezoidal.
Further, the outer surface of the knob 21 is provided with several non-slip grooves.
In order to non-slip when artificial choosing turns, the outer surface of knob 21 is provided with several non-slip grooves.
Further, cushion is additionally provided between first cam 5, second cam 6 and the driver plate 81
Plate.
It is moved due to the directly contact cam of driver plate 81, when rotate too fast, the momentum that driver plate 81 is subject to is bigger,
So buffer plate is arranged between cam and driver plate 81.
In conjunction with attached drawing, the embodiments of the present invention are described in detail above, but the present invention is not limited to described implementations
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen in protection scope of the present invention.
