Referring to fig. 1, in one aspect, the present invention provides a grip limiting structure 100, configured to limit a grip 200 on an adaptor 300, and prevent the grip 200 from affecting wiring when wiring is performed on a front panel of a single board.
Specifically, the grip limiting structure 100 comprises a pressing rod 101 and an elastic member 102, wherein the pressing rod 101 is rotatably installed in the grip 200 and is in a lever structure.
In the first end of the pressing rod 101 and the first position of the adaptor 300, one is provided with a protrusion 101a, the other is provided with a groove 301 for limiting the protrusion 101a, at least a part of the second end of the pressing rod 101 is exposed out of the holding member, as shown in fig. 2, and when the protrusion 101a is placed in the groove 301, the holding member is used for avoiding an external connection line on the front panel of the pluggable module 2000. It should be understood that the grip avoiding the external connection of the front panel of the pluggable module 2000 means that the grip is at a position perpendicular or approximately perpendicular to the front panel, so as to avoid interference when the front panel is externally connected, as shown in fig. 4.
The elastic member 102 is disposed in the grip 200, one end of the elastic member 102 is connected to or abutted against the grip 200, the other end of the elastic member 102 is connected to or abutted against the second end of the pressing rod 101, the elastic member 102 is used for driving the protrusion 101a to be disposed in or separated from the groove 301, and when the pressing rod 101 is pressed, the protrusion 101a is separated from or disposed in the groove 301. Taking the example that the pressing rod 101 is provided with the convex part 101a and the holding piece 200 is provided with the groove 301, the groove 301 can be arranged above the adaptor 300 or below the adaptor 300, when the groove 301 is arranged below the adaptor 300, the first end of the pressing rod 101 automatically falls into the groove 301 under the action of the elastic piece 102 at the moment, so that the angles of the adaptor 300 and the holding piece 200 are locked, and the rotation of the holding piece 200 can be transmitted to the adaptor 300; when the operator depresses the second end of the plunger 101, the angle of the adaptor 300 and the grip 200 is unlocked. When the groove 301 is formed above the adaptor 300, only when an operator presses down the second end of the pressing rod 101 at this time, the first end of the pressing rod 101 enters the groove 301, the adaptor 300 and the grip 200 are locked at an angle, the rotation of the grip 200 is transmitted to the adaptor 300, and when the operator releases the second end of the pressing rod 101, the adaptor 300 and the grip 200 are unlocked at an angle.
As shown in fig. 5, a U-shaped groove is formed on the adaptor 300 to rotatably mount the grip 200, and it should be noted that the upper side and the lower side of the adaptor 300 refer to two side walls of the U-shaped groove, respectively.
Specifically, the elastic member 102 is a constant diameter spring, a spiral spring, or the like.
According to the grip limiting structure 100 provided by the invention, in an initial state, the elastic piece 102 drives the protruding portion 101a to be separated from the groove 301, and the protruding portion 101a of the pressing rod 101 is arranged in the groove 301, for example, when external wiring is required to be connected on the front panel of a single plate, an external force drives the grip to rotate, so that the pressing rod 101 is driven to rotate, when the grip rotates to the position of the groove 301 corresponding to the adapter portion, the pressing rod 101 is pressed, the protruding portion 101a is arranged in the groove 301 under the action of the external force, the position of the pressing rod 101 is limited through the groove 301, so that the position of the grip is limited, and the grip can avoid the external wiring on the panel of the pluggable module 2000. In conclusion, when the front panel of the single board is wired, the invention avoids the holding piece from influencing the wiring.
In some embodiments, when the protrusion 101a is disposed at the first end of the pressing rod 101, a clamping groove 302 for clamping with the protrusion 101a is opened at the second position of the adaptor 300; when the groove 301 is formed in the first end of the pressing rod 101, a clamping protrusion used for being clamped with the groove 301 is arranged at the second position of the adapter 300; when the first end of the pressing rod 101 is clamped to the second position of the adaptor portion, the pressing rod is used for driving the adaptor 300 to push in or pull out the pluggable module 2000 under the action of external force.
It should be noted that, as shown in fig. 3, when the first end of the pressing rod 101 is snapped to the second position of the adaptor, the grip is parallel or substantially parallel to the front panel, so that an operator can conveniently grip the grip to push in or pull out the pluggable module 2000. That is, the angle between the engaging groove 302 and the recess 301 and the angle between the protrusion 101a and the engaging protrusion are both 90 °, or substantially 90 °.
In some embodiments, the second end of the pressing rod 101 is provided with a pressing protrusion 101b, and the holding member is provided with an avoiding hole 201 allowing the pressing protrusion 101b to pass through, so that an operator can press the pressing protrusion 101b to limit or release the limit of the holding member and the adapter.
In some embodiments, the shape of the groove 301 matches the shape of the protrusion 101a, so that when the first end of the pressing rod 101 is limited at the first position of the adaptor 300, the pressing rod 101 is locked on the adaptor, thereby realizing the locking of the holding member and the adaptor.
The groove 301 may be a trapezoidal groove, and the protrusion 101a may rotate by a preset angle in the groove 301 along with the holding part relative to the adaptor part, so as to realize that the angle between the adaptor 300 and the holding part is limited in a stepped manner. It should be noted that the groove 301 is not limited to be a trapezoidal groove, and other grooves 301 that can allow the protrusion 101a to rotate inside may be used, for example, an arc-shaped groove.
As shown in fig. 1, rotation of the projection 101a in the groove 301 means that the projection 101a rotates left and right along the groove 301.
In some embodiments, the pressing rod 101 is provided with a hinge hole 101c allowing a pin to pass through, and the pin is connected with the holding member, i.e. the pressing rod 101 and the holding member are rotatably connected through the pin.
