Of course, according to practical needs, the fixing frame 103 may be an integrally injection molded rubber member.

It should be noted that, the fixing frame 103 is disposed on the side of the tray 101, so that a lot of space on the tray 101 is not occupied, thereby reducing the size of the tray 101, reducing the occupied space of the tray 101, and being beneficial to saving the installation space of the motherboard 300 after the connection module 100 is installed above the motherboard 300.

Specifically, the tray 101 is provided with a first rotation connection hole, the rotation connection end 1032 is provided with a second rotation connection hole, the connection module 100 further includes a rotation connection member 105, the rotation connection member 105 is disposed along a first direction, and the rotation connection member 105 is configured to sequentially penetrate through the first rotation connection hole and the second rotation connection hole.

Of course, according to practical needs, the above-mentioned rotating connection member 105 may be a step rivet, and when in installation, the step rivet is riveted in the first rotating connection hole of the tray 101, then the second rotating connection hole of the fixing frame 103 is assembled to the step rivet, and finally the step rivet is expanded, so that the fixing frame 103 can be fixed on the tray 101 and simultaneously rotated.

In order to facilitate the fixing of the fixing end 1033, the fixing end 1033 is provided with a fixing hole, and the connection module 100 further includes a fixing member 106, where the fixing member 106 is configured to pass through the fixing hole and be fixedly connected with the tray 101.

When the screw is disassembled, the hand-turning screw is unscrewed.

In this embodiment, the movable buckle 104 includes a sleeve 1041, a movable rod 1042 and an elastic member, wherein the movable rod 1042 is disposed in the sleeve 1041, and the movable rod 1042 is configured to move relative to the sleeve 1041 along a second direction so as to extend into the positioning hole 201 of the side wall of the chassis 200; the elastic member is disposed in the sleeve 1041 and sleeved on the movable rod 1042, and the elastic member is configured to provide an elastic force along the axial direction of the movable rod 1042, so that the movable rod 1042 has a movement tendency of extending out of the sleeve 1041.

It will be appreciated that the initial state of the movable catch 104 is the state in which the movable rod 1042 extends out of the sleeve 1041, i.e. the movable catch 104 is in the closed state. The elastic member is specifically a compression (return) spring, the movable rod 1042 is provided with an annular protrusion protruding along the circumferential direction, the sleeve 1041 is provided with an axial through hole, the spring is arranged in the through hole of the sleeve 1041, and two ends of the spring respectively support between the annular protrusion and the sleeve 1041, so that when the movable rod 1042 is retracted, the spring is extruded and provides an elastic force capable of extending outwards for the movable rod 1042.

When the whole connection module 100 is installed in the chassis 200, as the connection module 100 is inserted downward, when the side wall of the chassis 200 touches the movable rod 1042 on the tray 101, the movable rod 1042 automatically retracts to the inner side of the sleeve 1041 under the extrusion of the side wall of the chassis 200, and at this time, the spring is pressed and provides an elastic force to the movable rod 1042 that can extend outwards; after the connection module 100 is inserted to the bottom, the movable rod 1042 just can extend out into the positioning hole 201 on the side wall of the chassis 200, at this time, since the movable rod 1042 releases the extrusion of the side wall, the movable rod 1042 automatically extends into the positioning hole 201 under the action of the elastic force of the spring. Thus, the entire connection module 100 can be firmly fixed in the cabinet 200.

Further, during disassembly, in order to facilitate the movable rod 1042 to retract into the sleeve 1041, thereby taking out the connection module 100, the movable buckle 104 further comprises a driving member 1043, the driving member 1043 is rotatably disposed on the movable rod 1042, the driving member 1043 can be rotatably connected to the movable rod 1042 through a pin, and the pin is disposed along an axis direction perpendicular to the movable rod 1042, so that the driving member 1043 can rotate relative to the movable rod 1042 along the axis direction perpendicular to the movable rod 1042, and the driving member 1043 is rotated to drive the movable rod 1042 to move along the axis direction thereof.

Of course, according to actual needs, the driving piece 1043 specifically includes a handle portion and two support arms relatively fixedly connected to the handle portion, where both the support arms are provided with pin holes for the pin shaft to pass through; meanwhile, the movable rod 1042 is provided with a through hole, and the axis of the through hole is perpendicular to the axis of the movable rod 1042.

In this way, the pin shaft can sequentially pass through the pin hole of one side support arm, the through hole of the movable rod 1042 and the pin hole of the other side support arm, thereby completing the rotation connection between the driving member 1043 and the movable rod 1042, and the driving member 1043 can rotate around the axis of the pin shaft. Of course, the two ends of the pin shaft can be provided with the protruding structures, so that the pin shaft is prevented from falling off.

It should be noted that, for the convenience of rotation, any arm is provided with an arc surface, and the arc surface is used for contacting with the end surface of the sleeve 1041 when the driving member 1043 rotates, so as to facilitate the rotation flexibility of the driving member 1043, thereby facilitating the conversion of the position state of the driving member 1043.

When the connection module 100 is installed in the chassis 200, the movable rod 1042 is in a state of extending out of the sleeve 1041, at this time, the driving member 1043 is in a horizontal position, and the elastic member is in a compressed/natural state. When the connection module 100 needs to be disassembled, the driving member 1043 is manually pulled to enable the driving member 1043 to be turned from the horizontal position to the vertical position (in this process, the driving member 1043 can be conveniently turned to the position state due to the arrangement of the cambered surface on the support arm), and at this time, the movable rod 1042 can retract the sleeve 1041 under the driving of the driving member 1043.

In addition, in order to prevent the movable rod 1042 from obstructing the travel of the connection module 100 when the connection module 100 is mounted downward to the cabinet 200, an end of the movable rod 1042 remote from the driving member 1043 is provided with a slope 10421 or a slope guide angle for guiding the connection module 100 when it is mounted downward to the cabinet 200. That is, when the connection module 100 is mounted to the chassis 200 downward, the inclined surface 10421 of the movable rod 1042 contacts the side wall of the chassis 200, and the movable rod 1042 automatically retracts along the sleeve 1041 under the extrusion action of the side wall of the chassis 200, which is beneficial to the connection module 100 to continue downward.

In order to improve the accuracy of the installation of the connection module 100, the connection module 100 further includes a guide pin 107 provided on the connection card assembly 102, the guide pin 107 being disposed along the first direction, the guide pin 107 being configured to cooperate with the guide hole 301 of the main board 300 to achieve the guiding.

When the assembled connection module 100 is assembled into the chassis 200, the guide pins 107 are aligned with the guide holes 301 on the main board 300, and at the same time, the plugs on the second connection card 1022 are aligned with the connectors on the main board 300 to be inserted downward, and as the connection module 100 is inserted downward, when the movable rod 1042 extends into the positioning holes 201 on the side wall of the chassis 200, the fixing of the whole connection module 100 can be completed.

The following specifically describes the mounting process of the connector card assembly 102 and the mounting process of the entire connector module 100 into the chassis 200.
