Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features.

[0029] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "mount", "connect", "be connected" should be understood in a broad sense.

[0031] A High-Speed Backplane Connector is a backplane connector used for data transmission, and is widely applied to high-performance electronic devices such as computer servers, communication devices, data storage systems, etc. It is mainly used to connect a backplane circuit board (Backplane) and a slot module (Module) to achieve high-speed and reliable data and signal transmission.

[0032] In the existing high-speed backplane connector, a certain number of pins need to be designed around the signal pins to achieve the purpose of optimizing high-speed transmission performance. However, the existing solution has high requirements for the manufacturing process. The ground pins on both sides are formed by each leading out one pin from the shielding plates on both sides to form a group. The ground pins and the signal pins are arranged vertically. The position of the ground pins is ensured by bending, and the cooperation between the conductive mounting plate and the ground pins requires multiple small-sized grounding pin holes. Affected by the position accuracy of the bent ground pins, there is a risk of inserting and hanging metal foreign objects in the cooperation between the conductive mounting plate and the ground pins, and the position accuracy of the ground pins is not easy to control.

[0033] The following embodiments provide a high-speed backplane connector, which can improve the position accuracy of the ground pins.

[0034] Please refer to Figure 1 and Figure 2 . Figure 1 FIG. is a three-dimensional structural schematic diagram of an embodiment of the high-speed backplane connector 100 of the present application. Figure 2 is Figure 1 an enlarged view of the partial view A in

[0035] In some embodiments, the high-speed backplane connector 100 includes a base 101, a plurality of signal transmission components 103 (only one is shown in the figure), and a conductive mounting member 105.

[0036] A plurality of signal transmission components 103 are stacked along the Y-axis and are respectively plugged into the base 101. In some embodiments, the base 101 can be made of plastic. Through the base 101, the plurality of signal transmission components 103 can be connected as a whole, which is more convenient for assembly. To connect the plurality of signal transmission components 103 as a whole, in addition to the base 101, there are other components (not shown in the figure), which are not related to the improvement points of this proposal and will not be explained in detail here.

[0037] Each signal transmission component 103 has a plurality of signal pins 107 and a plurality of ground pins 109.

[0038] The conductive mounting member 105 has a first avoidance hole 111 and a second avoidance hole 113 that penetrate along the first direction (the reverse direction of the X-axis). The signal pins 107 pass through the conductive mounting member 105 through the first avoidance hole 111 and are used for crimping to a circuit board (not shown in the figure). The ground pins 109 pass through the conductive mounting member 105 through the second avoidance hole 113 and are used for crimping to the circuit board. Crimping: The pins are inserted into the corresponding positions on the circuit board, and then an appropriate amount of pressure is applied. Through compression, cold welding or deformation of the metal occurs between the pins and the pads, thereby establishing a reliable electrical connection. The conductive mounting member 105 is electrically connected to the ground pins 109 in each signal transmission component 103 respectively. In other embodiments, the conductive mounting member 105 can be selectively electrically connected to some of the ground pins 109 in some signal transmission components 103.

[0039] Please refer to Figure 3 together. Figure 3 is a three-dimensional exploded view of the signal transmission component 103 in an embodiment of the high-speed backplane connector 100 of this application.

[0040] In some embodiments, the signal transmission component 103 includes a reed component 115, a first shielding member 117, and a second shielding member 119. The reed component 115 includes an insulating member 121 and a plurality of conductive terminals 123. The conductive terminals 123 are embedded in the insulating member 121, one end is located outside the insulating member 121 to form the signal pins 107, and the other end is located outside the insulating member 121 for plugging and mating with the conductive terminals 123 of another high-speed backplane connector 100. The first shielding member 117 and the second shielding member 119 are respectively disposed on opposite sides of the insulating member 121 for electromagnetic shielding of the conductive terminals 123. In some embodiments, both the first shielding member 117 and the second shielding member 119 are made of metal.

[0041] Please refer to Figure 4 , Figure 5 and Figure 6 together. Figure 4 is a schematic diagram of the assembled state of the first shielding member 117 and the reed component 115 in an embodiment of the high-speed backplane connector 100 of this application.Figure 5 It is a schematic diagram of a state in which the first shielding member 117 and the spring assembly 115 are separated in an embodiment of the high-speed backplane connector 100 of the present application. Figure 6 yes Figure 2 BB section view in.

[0042] In some embodiments, the insulating member 121 has a first surface 125, a second surface 127, and a third surface 129 that are sequentially connected and formed into a step shape along a first direction (opposite to the X-axis). The conductive terminal 123 is embedded in the insulating member 121, a portion of which extends out of the insulating member 121 along the first direction and is used to be crimped into the circuit board along the first direction. The conductive terminal 123 is used to transmit signals. The first shielding member 117 includes a shielding body 131, a connecting portion 133, and a plug-in portion 135 that are sequentially connected along the first direction. The shielding body 131 covers and is fixedly mounted on the first surface 125. The connecting portion 133 is bent from the edge of the shielding body 131 and is disposed opposite to the second surface 127. The plug-in portion 135 is bent from the edge of the connecting portion 133 and is disposed opposite to the third surface 129. One end of the plug-in portion 135 that is away from the connecting portion 133 is used to be crimped into the circuit board along the first direction. The conductive mounting member 105 presses the plug-in portion 135 against the third surface 129 , and the plug-in portion 135 and the insulating member 121 are concave-convexly matched along the normal direction (positive or negative direction of the Y axis) of the third surface 129 .

[0043] Specifically, the shielding body 131 is in a flat plate shape and is attached to the first surface 125 , so that the space occupied by the shielding body 131 in the stacking direction of the plurality of signal transmission components 103 can be reduced, thereby reducing the volume of the high-speed backplane connector 100 .

[0044] Specifically, the insulating member 121 is generally in the shape of a flat plate, and the first shielding member 117 and the second shielding member 119 are respectively arranged on both sides of the thickness direction of the insulating member 121. The thickness of the insulating member 121 at the third surface 129 is thinner than that at the first surface 125, so that the plug-in portion 135 is offset toward the second shielding member 119 in the normal direction of the third surface 129 relative to the shielding body 131, thereby making the ground pin 109 (the portion of the plug-in portion 135 for crimping) and the signal lead (the portion of the conductive terminal 123 for crimping) in the normal direction of the third surface 129 consistent in height.

[0045] Specifically, the plug-in portion 135 has two ground pins 109 spaced apart along the Z axis, and the two ground pins 109 respectively pass through the conductive mounting member 105 through the second avoidance hole 113 and are respectively used for crimping in the circuit board. Among them, a plurality of signal pins 107 are spaced apart along the Z axis. In other embodiments, the number of ground pins 109 may also be one or more than three.

[0046] Specifically, both the ground pin 109 (the portion of the insertion part 135 for crimping) and the signal pin 107 (the portion of the conductive terminal 123 for crimping) can be elastically deformed along the second direction (the positive or negative direction of the Z-axis), and the second direction intersects with the first direction. In the illustrated embodiment, both the ground pin 109 and the signal pin 107 are fish-eye terminals.

[0047] Specifically, the first shielding member 117 is integrally formed by stamping. The shielding main body 131 and the connecting portion 133 form a first bending angle, and the connecting portion 133 and the insertion portion 135 form a second bending angle. Due to manufacturing errors of the first bending angle and the second bending angle, the positional accuracy of the insertion portion 135 relative to the shielding main body 131 is low. When the shielding main body 131 is fixed to the insulating member 121, the positional accuracy of the insertion portion 135 relative to the insulating member 121 is low.

[0048] In the embodiment of the present application, the conductive mounting member 105 presses the insertion portion 135 against the third surface 129, so that the freedom degree of the insertion portion 135 (the ground pin 109) in the normal direction of the third surface 129 is restricted. The insertion portion 135 and the insulating member 121 are in concave-convex fit along the normal direction of the third surface 129, so that the freedom degree of the insertion portion 135 in any direction parallel to the third surface 129 is restricted. Thus, the positional accuracy of the insertion portion 135 can be guaranteed.

[0049] In addition, due to manufacturing errors of the first bending leg and the second bending angle, after the first shielding member 117 is mounted on the insulating member 121, there is a reserved gap between the connecting portion 133 and the second surface 127. In the related art, the existence of this gap causes the ground pin 109 to retreat in the reverse direction of the first direction when the ground pin 109 is crimped, that is, to move toward the shielding main body 131 side, resulting in abnormal crimping. In the embodiment of the present application, through the concave-convex fit of the insertion portion 135 and the insulating member 121 along the normal direction of the third surface 129, the insertion portion 125 is limited in the first direction, so that the ground pin 109 can be prevented from retreating during crimping.

[0050] The structures of the limiting fit between the insertion portion 135 and the insulating member 121 and the conductive mounting member 105 will be introduced in detail below.

[0051] Please refer to Figures 4 to 6 . In some embodiments, the insertion portion 135 includes an insertion main body portion 137 and an abutting portion 139.

[0052] The plug-in body is in the shape of a plate, and the thickness direction is consistent with the normal direction of the third surface 129. The plug-in body portion 137 is bent from the edge of the connecting portion 133 and is arranged relative to the third surface 129, and the end of the plug-in body portion 137 away from the connecting portion 133 forms a ground pin 109. The plug-in body portion 137 passes through the conductive mounting member 105 through the second avoidance hole 113, and is used to be crimped into the circuit board along the first direction. The plug-in portion 135 has a limiting hole 141 that passes through the normal direction of the third surface 129. Specifically, in the illustrated embodiment, the limiting hole 141 is a square hole. In other embodiments, the limiting hole 141 may also be a circular hole or an irregularly shaped hole. In the illustrated embodiment, the limiting hole 141 passes through the plug-in portion 135. In other embodiments, the limiting hole 141 may not pass through.

[0053] The abutment portion 139 is convexly disposed on a surface of the plug body portion 137 that faces away from the third surface 129. Specifically, the abutment portion 139 is located at an edge of the limiting hole 141 of the plug body.

[0054] In some embodiments, the limiting hole 141 and the abutting portion 139 are formed by a stamping process.

[0055] The insulating member 121 has a limiting portion 143 protruding from the third surface 129. The shape and size of the limiting portion 143 match the limiting hole 141. The limiting portion 143 passes through the inserting portion 135 through the limiting hole 141, thereby forming a concave-convex fit.

[0056] The conductive mounting member 105 abuts against the abutting portion 139 and presses the plug body portion 137 against the third surface 129 .

[0057] The positions of the limiting hole 141 and the limiting portion 143 may also be reversed, that is, the limiting hole 141 is located on the third surface 129 of the insulating member 121 , and the limiting portion 143 is protruded on the side of the plug-in body 137 facing the third surface 129 .

[0058] The location of the abutting portion 139 can also be adjusted to the conductive mounting member 105 , that is, the conductive mounting member 105 abuts against the plug-in main body 137 through the abutting portion 139 .

[0059] The structure of the plug-in portion 135 and the insulating member 121 and the conductive mounting member 105 respectively limiting the matching is not limited to Figures 4 to 6 As shown, another limit matching structure is introduced below.

[0060] See also Figures 7 to 9 . Figure 7 1 is a schematic diagram of the assembly state of the first shielding member 117 and the spring assembly 115 in an embodiment of the high-speed backplane connector 100 of the present application. Figure 8It is a schematic diagram of the separated state of the first shielding member 117 and the reed assembly 115 in an embodiment of the high-speed backplane connector 100 of the present application. Figure 9 It is a cross-sectional view of the assembled state of the signal transmission component 103 and the conductive mounting member 105 in an embodiment of the high-speed backplane connector 100 of the present application.

[0061] In some embodiments, the insertion portion 135 includes an insertion main body portion 137 and an abutting portion 139. The insertion main body portion 137 penetrates through the conductive mounting member 105 through the second avoidance hole 113 and is used for crimping onto the circuit board along the first direction. The abutting portion 139 protrudes from one surface of the insertion main body portion 137 facing away from the third surface 129. The abutting portion 139 forms a limiting groove 145 on one surface of the insertion main body portion 137 facing the third surface 129, and the inner wall surface of the limiting groove 145 is spherical. Among them, the conductive mounting member 105 abuts against the abutting portion 139 and presses the insertion main body portion 137 against the third surface 129. The insulating member 121 has a limiting portion 143 protruding from the third surface 129. The shape and size of the limiting portion 143 match those of the limiting groove 145 and are accommodated in the limiting groove 145, thereby forming a concave-convex fit.

[0062] In summary, the high-speed backplane connector 100 provided by the embodiments of the present application can improve the position accuracy of the ground pins 109.
