Based on this, referring to fig. 2, in an embodiment of the present application, a network card connection assembly 10 is provided, and is used for connecting to a communication connector (not shown in the figure), where the network card connection assembly 10 includes: a connection board 101, a wiring board 102, and a fixing member 103.

The connection plate 101 is provided with a connection hole 1011, and the wiring board 102 is located on one side (e.g., a side a in fig. 2) of the connection plate 101 in the depth direction F1 of the connection hole 1011 and is connected to the connection plate 101. Thus, the communication connector can be connected to the wiring board 102 through the connection hole 1011.

The number of the fixing pieces 103 is set to at least two, and the fixing pieces 103 are located on the other side (e.g., side B in fig. 2) of the connection plate 101 in the depth direction F1 of the connection hole 1011 and are connected to the connection plate 101.

At least two fixing members 103 are arranged around the connecting hole 1011 at intervals, and different fixing members 103 can be connected with the communication connector from different directions, so that the stability of fixing the communication connector can be improved.

Illustratively, as shown in fig. 2, the number of the fixing members 103 is two, and the two fixing members 103 are disposed at intervals around the connection hole 1011 and are disposed opposite to each other in the first direction F2. The first direction F2 is perpendicular to the depth direction F1 of the connection hole 1011 and parallel to the plane in which the contact 1021 of the wiring board 102 is located. The two fixing members 103 can be abutted against the communication connector at two opposite sides in the first direction F2 at the same time, so that the stability of fixing the communication connector is improved.

In other embodiments, the two fixing members 103 may be disposed opposite to each other along a depth direction F1 perpendicular to the connection hole 1011 and perpendicular to the first direction F2.

Illustratively, as shown in fig. 3, the number of the fixing members 103 is three, and the three fixing members 103 are disposed at intervals around the connection hole 1011. Two of the three fixing members 103 may be simultaneously abutted against the communication connector in the first direction F2, and the other one is abutted against the communication connector in the depth direction F1 perpendicular to the connection hole 1011 and perpendicular to the first direction F2, thereby improving the stability of fixing the communication connector.

In addition, the fixing piece 103 can also move towards the direction away from the communication joint, so that the communication joint is separated from the fixing piece, and the communication joint is convenient to detach.

As shown in fig. 2, the number of the fixing members 103 is two, when the communication connector is plugged into the connection hole 1011, the two fixing members 103 are respectively moved along the first direction F2 in a direction away from the connection hole 1011, the communication connector is plugged into the connection port, and then the two fixing members 103 are respectively moved along the first direction F2 in a direction close to the connection hole 1011, so that the two fixing members 103 are abutted against the outer surface of the communication connector, and the fixation of the communication connector is completed. When the communication connector is separated from the connecting hole 1011, the two fixing members 103 are respectively moved along the first direction F2 in a direction away from the connecting hole 1011, so that the two fixing members 103 are separated from the outer surface of the communication connector, the fixing of the communication connector by the fixing members 103 is released, and the communication connector is pulled out.

As shown in fig. 3, the number of the fixing members 103 is three, when the communication connector is plugged into the connection hole 1011, the three fixing members 103 are respectively moved in a direction away from the connection hole 1011, the communication connector is plugged into the connection port, and then the three fixing members 103 are respectively moved in a direction close to the connection hole 1011, so that the three fixing members 103 are abutted with the outer surface of the communication connector, and the fixing of the communication connector is completed. When the communication connector is separated from the connecting hole 1011, the three fixing members 103 are respectively moved in a direction away from the connecting hole 1011, so that the three fixing members 103 are separated from the outer surface of the communication connector, the fixing of the communication connector by the fixing members 103 is released, and the communication connector is pulled out.

As shown in fig. 4, the number of the fixing members 103 is four, when the communication connector is plugged into the connection hole 1011, the four fixing members 103 are respectively moved in a direction away from the connection hole 1011, the communication connector is plugged into the connection port, and then the four fixing members 103 are respectively moved in a direction close to the connection hole 1011, so that the four fixing members 103 are abutted with the outer surface of the communication connector, and the fixing of the communication connector is completed. When the communication connector is separated from the connecting hole 1011, the four fixing members 103 are respectively moved in a direction away from the connecting hole 1011, so that the four fixing members 103 are separated from the outer surface of the communication connector, the fixing of the communication connector by the fixing members 103 is released, and the communication connector is pulled out.

In other embodiments, to facilitate adjusting the position of the fixing member, a handle is further mounted on the fixing member 103, and the handle is mounted on a side of the fixing member 103 away from the connection hole 1011.

Therefore, the network card connecting assembly 10 provided by the embodiment of the application can solve the problem of poor connection stability of the existing network card connecting assembly 10 during wiring.

In some embodiments, a network card connector assembly 10 is provided that further includes a locking member (not shown in fig. 2) that is coupled to the connector plate 101 and removably coupled to the fixing member 103. The locking member can connect the connecting plate 101 with the fixing member 103 when the fixing member 103 abuts against the communication connector, so that the fixing member 103 and the connecting plate 101 are relatively fixed, and the fixing member 103 is used for fixing the communication connector.

In some embodiments, with continued reference to fig. 2, the network card connecting assembly 10 further includes an elastic member 104, where two ends of the elastic member 104 are respectively connected to the connecting plate 101 and the fixing member 103, and the fixing member 103 is used to abut against the communication connector under the elastic force of the elastic member 104.

It will be appreciated that the resilient member 104 has an elastic restoring force in the event of elastic deformation. When the two ends of the elastic member 104 are fixed to the connecting plate 101 and the fixing member 103, and the fixing member 103 abuts against the communication connector, the elastic member 104 is in a compressed state, and an elastic restoring force of the elastic member 104 acts on the fixing member 103, so that the fixing member 103 can abut against the communication connector.

In some embodiments, referring to fig. 5 in combination with fig. 2, the network card connection assembly 10 further includes a connector 105, where the connector 105 is located on a side of the connection board 101 adjacent to the circuit board 102 and is connected to the connection board 101.

The plug 105 is provided with a slot 1051, and a slot 1052 of the slot 1051 is oriented toward the connection hole 1011 and communicates with the connection hole 1011. Thus, the communication connector can be inserted into the slot 1051 of the connector 105 through the connection hole 1011 of the connection board 101.

The connector 105 is further provided with a through hole 1053 communicating with the slot 1051, and the contact 1021 of the circuit board 102 extends into the slot 1051 through the through hole 1053, so that the communication connector passes through the connection hole 1011 of the connection board 101 to be connected with the circuit board 102 in the slot 1051 of the connector 105. In addition, the connection between the communication interface and the circuit board 102 can be protected by the plug connector 105, so that the connection between the communication interface and the circuit board 102 is more stable.

In some embodiments, referring again to fig. 2, a projection of the slot 1052 of the plug 105 along the depth direction F1 of the connection bore 1011 is located within the connection bore 1011.

It will be appreciated that the projection of the slot 1052 of the connector 105 along the depth direction F1 of the connection hole 1011 is located in the connection hole 1011, so that the socket of the slot 1051 of the connector 105 is smaller than the connection hole 1011, and the communication connector is more tightly connected with the circuit board 102 through the connection hole 1011 of the connection board 101. Meanwhile, the projection of the notch 1052 of the connector 105 along the depth direction F1 of the connection hole 1011 is also arranged in the connection hole 1011 to prevent the space in the slot 1051 of the connector 105 from being too large, so that the communication interface is easy to shake when being connected with the circuit board 102, and the unstable connection between the communication interface and the circuit board 102 can be avoided, thereby causing disconnection.

Referring to fig. 6, in some embodiments, a guide groove 1012 is provided on a side of the connection board 101 facing away from the circuit board 102, the fixing member 103 is slidably engaged with the guide groove 1012, and the elastic member 104 is provided in the guide groove 1012.

It can be appreciated that, the elastic element 104 is disposed in the guide groove 1012, so that the elastic element 104 can move along the extending direction of the guide groove 1012, the fixing element 103 can slide along the guide groove 1012 in a matching manner, and the moving track of the fixing element 103 can be limited, so that under the action of the guide groove 1012, the elastic element 104 and the guide groove 1012 can be better matched to realize the abutting connection of the communication connector.

In some embodiments, referring again to fig. 6, the securing member 103 is movable in a direction toward or away from the centerline of the connection hole 1011, thereby enabling the securing member 103 to abut and unsecure the communication connector.

The fixing member 103 is provided with a gasket 1032 on a side facing the center line of the connection hole 1011, so that the fixing member 103 can be abutted against the communication connector more firmly and the communication connector can be protected.

When the fixing member 103 moves toward the direction close to the center line of the connection hole 1011, the fixing member 103 can perform position limitation on the communication connector, the gasket 1032 of the fixing member 103 abuts against the communication connector, and the fixing member 103 completes position limitation on the communication connector. When the fixing member 103 moves in a direction away from the center line of the connection hole 1011, the gasket 1032 of the fixing member 103 is disengaged from the communication terminal, and the fixing member 103 releases the positional restriction of the communication terminal.

The material of the gasket 1032 may also be provided as a somewhat resilient material, such as rubber, silicone, cork, nitrile rubber, or the like, for example.

In some embodiments, at least one of the two opposite side walls of the guide groove 1012 is provided with a guide part 1013, and the fixing member 103 is provided with at least one sliding part 1031, and one guide part 1013 is slidably engaged with one sliding part 1031.

Illustratively, referring to fig. 7, the opposite side walls of the guide groove 1012 are provided with guide portions 1013, and the fixing member 103 is provided with two sliding portions 1031, one of the guide portions 1013 slidably engaging with one of the sliding portions 1031. The guide part 1013 and the slide part 1031 are in concave-convex engagement.

In this way, when the guide portion 1013 of the guide groove 1012 is engaged with the slide portion 1031 of the fixing tool 103 in a concavo-convex sliding manner, the slide path of the fixing tool 103 is further limited to the slide groove, and the derailment phenomenon is less likely to occur.

It can be understood that, when the two ends of the elastic member 104 are respectively connected with the connecting plate 101 and the fixing member 103, and when one guiding portion 1013 is in concave-convex fit with one sliding portion 1031, the direction of the elastic force of the elastic member 104 is further limited, so that the fixing member 103 is limited in the sliding groove and is not easy to fall.

In some embodiments, referring to fig. 8, the side of the circuit board 102 facing away from the contacts 1021 is provided as a planar surface for placement on a carrier platform. It will be appreciated that the circuit board 102 is intended to be placed on a carrier platform, and that the side of the circuit board 102 facing away from the contacts 1021 should be planar in order for the circuit board 102 to be stable for use on the carrier platform. The first direction F2 is perpendicular to the depth direction F1 of the connection hole 1011 and parallel to the plane.

The network card connecting assembly 10 further includes a plurality of first positioning members 106, where the first positioning members 106 are connected to the connecting plate 101 and abut against the circuit board 102.

One part of the plurality of first positioning members 106 is located on one side (a side as shown in fig. 8) of the circuit board 102 in the first direction F2, and the other part is located on the other side (B side as shown in fig. 8) of the circuit board 102 in the first direction F2, and the first positioning members 106 are connected to the connection board 101 and abut against the circuit board 102.

In this way, the two sides of the circuit board 102 in the first direction F2 can be limited, and then the connection between the circuit board 102 and the connecting board 101 can be reinforced, so that the circuit board 102 is not easy to shake, the communication interface and the circuit board 102 are prevented from being broken, and the use experience effect of a user can be improved.

In some embodiments, with continued reference to fig. 8, the network card connecting assembly 10 further includes at least one second positioning member 107, where the at least one second positioning member 107 is located on a side of the circuit board 102 in a direction perpendicular to the plane and on a side of the contact 1021, and the at least one second positioning member 107 is connected to the connecting board 101 and abuts against the circuit board 102.

It can be appreciated that the second positioning member 107 is connected to the connection board 101, and abuts against the circuit board 102 to further fix the position of the circuit board 102. And at least one second positioning member 107 is located on the side of the wiring board 102 in the direction perpendicular to the plane, and on the side where the contacts 1021 are located in order to define the wiring board 102 in the direction perpendicular to the plane.

In this way, since the side of the circuit board 102 facing away from the contacts 1021 is set to be a plane and placed on the carrying platform, the circuit board 102 is limited in the direction perpendicular to the plane and the first direction F2 and parallel to the plane, and the position of the circuit board 102 is more fixed and the connection with the connection board 101 is more stable.

In some embodiments, with continued reference to fig. 8, a positioning portion 108 is further disposed on a side of the connection board 101 adjacent to the circuit board 102, where the positioning portion 108 includes a first positioning surface 1081 and a second positioning surface 1082, and may be used to position the circuit board 102.

The first positioning surface 1081 is parallel to the plane and cooperates with a side of the connection plate 101 facing away from the plane. The second positioning surface 1082 is perpendicular to the first direction F2, and is matched with at least one side of the circuit board 102 in the first direction F2. In this way, the position of the circuit board 102 can be restricted to be more accurate by the mutual matching of the two positioning surfaces.

The first positioning member 106 passes through the first positioning surface 1081 to be abutted against the circuit board 102, and the at least one second positioning member 107 passes through the second positioning surface 1082 to be abutted against the circuit board 102, so that the circuit board 102 can be more stable through the reinforcement of the positioning members on the basis of the positioning surfaces.

Illustratively, the first positioning member 106 and the second positioning member 107 may be connected to the positioning portion 108 by screws, bolts, or the like.

In the description of the present specification, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.
