Description

Technical Field

[0001] This application relates to the technical field of connectors, and particularly to a backplane connector. Background Art

[0002] Backplane connectors are applied in communication technologies, for example, in large communication devices, ultra-high performance servers, supercomputers, industrial computers, and high-end storage devices. In backplane connectors, due to structural limitations, crosstalk between differential signal pairs is severe, which has a great impact on the signal transmission quality. With the increase in the transmission rate of backplane connectors, in order to ensure that the backplane connector has a good return path and less crosstalk, the signal return path is shortened and the high-speed performance is improved by changing the shielding sheet structure and the contact method of the shielding part in the mating area.

[0003] Currently, a conductive mounting member is provided at the crimping end of the backplane connector. The conductive mounting member shields the conductive terminals, reduces signal interference between the conductive terminals, and improves the high-frequency performance of the product. In the prior art, the conductive mounting member is prone to falling off, which affects the efficiency of crimping the backplane connector to the circuit board. Summary of the Invention

[0032] Backplane connectors are applied to communication technologies. A pair of backplane connectors is used to mechanically and electrically connect a daughter board and a backplane in an orthogonal manner. Both the daughter board and the backplane are circuit boards.

[0033] Please refer to Figure 1 and Figure 2 . Figure 1 FIG. 1 is a three-dimensional structural schematic diagram of an embodiment of a backplane connector 10 of the present application. Figure 2 FIG. 2 Figure 1 is a three-dimensional exploded view of the backplane connector 10 shown in FIG. 1.

[0034] In some embodiments, the backplane connector 10 includes a plurality of signal transmission modules 200, a base 100, and a conductive mounting member 300.

[0035] Each signal transmission module 200 has a plug-in end 201 and a crimping end 202. The signal transmission module 200 has signal pins (not shown in the figure) at the crimping end 202, and is crimped and mated with the circuit board through the signal pins for electrical connection. The signal transmission module 200 has conductive elastic pieces (not shown in the figure) at the plug-in end 201, and is plugged and mated with another backplane connector through the conductive elastic pieces for electrical connection. The signal transmission module 200 is used for transmitting signals.

[0036] In a scenario of assembling the backplane connector 10 to the circuit board, first, a plurality of signal transmission modules 200 are assembled to the base 100, then the conductive mounting member 300 is assembled to the plurality of signal transmission modules 200 to form the backplane connector 10, and then the backplane connector 10 is crimped to the circuit board. Specifically, the crimping direction is the positive direction of the Z axis.

[0037] Crimping is a connection technology that firmly connects two or more objects by applying pressure. During the crimping process, by applying appropriate pressure, sufficient force is generated between the contact surfaces of two or more objects to establish a connection. Crimping can be performed based on different principles and methods, including mechanical extrusion, thermocompression bonding, ultrasonic crimping, cold crimping, etc.

[0038] The plurality of signal transmission modules 200 are sequentially stacked along the X axis and installed on the base 100. In FIGS. 1 and 2, only two signal transmission modules 200 are shown to make the view more concise. The specific structures of the respective signal transmission modules 200 may be the same or different. Figure 1 and Figure 2 FIG. 2

[0039] The base 100 integrates the plurality of signal transmission modules 200 into a whole, thereby facilitating the assembly of the plurality of signal transmission modules 200 to the circuit board. The base 100 is provided with through holes (not shown in the figure) corresponding to the plug-in ends 201 of the signal transmission modules 200 to avoid the conductive elastic pieces.

[0040] The connection structure between the signal transmission module 200 and the base 100 does not involve the improvement points of this application and can refer to existing related designs, which will not be elaborated here. The improvement points of this application mainly lie in the connection structure between the conductive mounting member 300 and the signal transmission module 200, which will be described in detail below.

[0041] Please refer to Figure 3 and Figure 4 . Figure 3 is Figure 1 the front view of the crimping end 202 of the backplane connector 10 shown. Figure 4 is Figure 3 the enlarged view of the partial view A in

[0042] The conductive mounting member 300 is disposed at the crimping end 202 of the signal transmission module 200 and is respectively in limit cooperation with a plurality of signal transmission modules 200 to define the positional accuracy of the signal pins 203 of each signal transmission module 200, so as to facilitate the assembly of the plurality of signal transmission modules 200 to the circuit board. The conductive mounting member 300 is also used for electrically connecting with the shielding member in the signal transmission module 200 to increase the return path. The conductive mounting member 300 is provided with a through hole 302 to avoid the signal pins 203. The conductive mounting member 300 isolates the plurality of signal pins 203 in each signal transmission module 200 from each other, avoiding crosstalk between the signal pins 203.

[0043] In some embodiments, the conductive mounting member 300 is made of plastic material and has a metal coating on its outer surface. In other embodiments, the conductive mounting member 300 is conductive plastic.

[0044] In the related art, the conductive mounting member 300 is prone to falling off, affecting the efficiency of crimping the backplane connector 10 to the circuit board. In the embodiments of this application, in order to improve the mounting firmness of the conductive mounting member 300, the following improvements are made.

[0045] Please refer to Figures 5 to 7 . Figure 5 is Figure 1 the three-dimensional view of the partial structure of the signal transmission module 200 in the backplane connector 10 shown. Figure 6 is Figure 1 the three-dimensional view of the partial structure of the conductive mounting member 300 in the backplane connector 10 shown. Figure 7 is Figure 4 the sectional view taken along B-B in

[0046] In some embodiments, the signal transmission module 200 includes a carrier body 204 and conductive terminals 205. The conductive terminals 205 are embedded in the carrier body 204, and a part thereof extends out of the carrier body 204 along the first direction Z to form signal pins 203. The conductive mounting member 300 has a receiving groove 301 and a through hole 302. The receiving groove 301 opens in the reverse direction of the first direction Z, and the through hole 302 is provided at the bottom of the receiving groove 301 and penetrates the conductive mounting member 300 along the first direction Z. Wherein, a part of the carrier body 204 is inserted into the receiving groove 301 along the first direction Z and abuts against the side wall surface 303 of the receiving groove 301 to limit the separation of the conductive mounting member 300 from the carrier body 204, and the signal pins 203 pass through the conductive mounting member 300 through the through hole 302.

[0047] Specifically, the receiving groove 301 includes a bottom wall surface 304 and side wall surfaces 303 surrounding the bottom wall surface 304. Among them, the through hole 302 is opened on the bottom wall surface 304.

[0048] Specifically, the exposed part of the signal pin 203 passing through the conductive mounting member 300 is used for crimping in the circuit board. In some embodiments, as Figure 5 shown, the signal pin 203 is in the shape of a fish-eye terminal.

[0049] Specifically, a pair of signal pins 203 pass through the conductive mounting member 300 through the same through hole 302, and this pair of signal pins 203 can be used to transmit a pair of differential signals. The conductive mounting member 300 surrounds the pair of signal pins 203 and separates them from the rest of the signal pins 203 to form a shield.

[0050] In this technical solution, a part of the carrier body 204 is inserted into the receiving groove 301 along the first direction Z and abuts against the conductive mounting member 300 in the radial direction of the receiving groove 301 to form a tight fit, so as to limit the separation of the conductive mounting member 300 from the carrier body 204. Thus, the mounting firmness of the conductive mounting member 300 is increased, and the risk of the conductive mounting member 300 falling off is reduced. In addition, the carrier body 204 and the conductive mounting member 300 are in concave-convex fit along the first direction Z, so that their degrees of freedom in the plane perpendicular to the first direction Z are restricted, thereby restricting the position of the signal pins 203 relative to the conductive mounting member 300. When each signal transmission module 200 is in concave-convex fit with the conductive mounting member 300 along the first direction Z, the positional accuracy of the multiple signal pins 203 of the backplane connector 10 can be ensured.

[0051] Please refer to Figure 8 together. Figure 8 is Figure 5 the three-dimensional exploded view of the partial structure shown.

[0052] In some embodiments, the carrier body 204 includes an insulating member 206, a first shielding member 207, and a second shielding member 208. The first shielding member 207 is attached to one surface of the insulating member 206 along the second direction X. The second shielding member 208 is attached to the other surface of the insulating member 206 along the second direction X. The second direction X is perpendicular to the first direction Z. Wherein, the conductive terminal 205 is embedded in the insulating member 206, and a part thereof extends out of the insulating member 206 along the first direction Z to form a signal pin 203. The insulating member 206, the first shielding member 207, and the second shielding member 208 all extend into the receiving groove 301, and the side wall surface 303 of the receiving groove 301 presses the first shielding member 207 and the second shielding member 208 against the insulating member 206 respectively.

[0053] That is to say, the conductive mounting member 300 is clamped to the carrier body 204 along the second direction X, so as to be held on the carrier body 204 by static friction.

[0054] In some embodiments, the first shielding member 207 includes a shielding body 209 and a convex bump 210. The shielding body 209 is attached to one surface of the insulating member 206 along the second direction X. The convex bump 210 protrudes from one surface of the shielding body 209 facing away from the insulating member 206. Wherein, the convex bump 210 is in contact with the side wall surface 303 of the receiving groove 301 along the second direction X. The conductive mounting member 300 is electrically connected to the shielding body 209 through the convex bump 210.

[0055] Specifically, the first shielding member 207 can be a sheet metal part. By stamping, the convex bump 210 is formed on the shielding body 209. The convex bump 210 is recessed on one side of the shielding body 209 facing the insulating member 206 and protrudes on the other side of the shielding body 209 facing away from the insulating member 206.

[0056] When assembling the conductive mounting member 300, the end of the shielding body 209 along the first direction Z is inserted into the receiving groove 301 and does not contact the conductive mounting member 300. As the shielding body 209 is inserted into the receiving groove 301, the convex bump 210 enters the receiving groove 301 and is in contact with the side wall surface 303 of the receiving groove 301 along the second direction X.

[0057] Due to manufacturing errors or assembly errors, the end of the shielding body 209 along the first direction Z cannot completely fit the insulating member 206, and there is a certain degree of warping, resulting in interference in assembling the conductive mounting member 300. In the embodiments of the present application, by providing the convex bump 210, interference between the shielding body 209 and the conductive mounting member 300 can be avoided.

[0058] In the case where the first shielding member 207 does not have the convex hull 210, the first shielding member 207 is in surface contact with the conductive mounting member 300. Due to manufacturing errors or assembly errors, the two cannot be completely fitted, resulting in an uncertain contact position. In this embodiment, the first shielding member 207 contacts the conductive mounting member 300 at the convex hull 210, ensuring a stable contact position and meeting expectations. When the first shielding member 207 and the conductive mounting member 300 are electrically connected through the contact portion, setting the convex hull 210 can maintain a stable electrical connection.

[0059] Similarly, the second shielding member 208 can also adopt a structure similar to that of the first shielding member 207, that is, including a shielding body and a convex hull. Details are not described herein again.

[0060] In some embodiments, the first shielding member 207 further includes a barb portion 211. The barb portion 211 is provided on the shielding body 209 and protrudes from the insulating member 206 along the third direction Y. The third direction Y is perpendicular to the first direction Z and the second direction X respectively, and the barb portion 211 is embedded in the conductive mounting member 300. The conductive mounting member 300 is electrically connected to the shielding body 209 through the barb portion 211.

[0061] In some embodiments, the number of the barb portions 211 is at least two (two in the illustrated embodiment), and the two barb portions 211 are arranged on opposite sides of the first shielding body 209 along the third direction Y.

[0062] Specifically, the shielding body 209, the convex hull 210, and the barb portion 211 are integrally formed by a stamping process.

[0063] When assembling the conductive mounting member 300, as the shielding body 209 is inserted into the receiving groove 301, the barb portion 211 cuts through the side wall surface 303 of the receiving groove 301 and is embedded in the conductive mounting member 300.

[0064] First, by setting the barb portion 211 in the embodiment of the present application, the holding force between the conductive mounting member 300 and the first shielding member 207 can be improved, and further the risk of the conductive mounting member 300 falling off is reduced. Second, the barb portion 211 is embedded in the conductive mounting member 300, which can also improve the effect of electrical connection. Third, the barb portion 211 and the convex hull 210 are located at different positions of the first shielding member 207 respectively. By setting the barb portion 211, the conductive contact positions between the conductive mounting member 300 and the first shielding member 207 can be increased, and the return current path is increased.

[0065] The second shielding member 208 can also be provided with barb portions, details are not described herein again.

[0066] Please refer to Figure 5 and Figure 6 .

[0067] In some embodiments, the conductive mounting member 300 is pressed against the carrier body 204 in the reverse direction of the first direction Z.

[0068] Specifically, the insulating member 206 in the carrier body 204 has a first abutting portion 212, and the first abutting portion 212 is a plane. The conductive mounting member 300 has a second abutting portion 305, and the second abutting portion 305 is the end face of the conductive mounting member 300 facing the carrier body 204 in the first direction Z. The accommodating groove 301 is opened on this end face. In the state where the conductive mounting member 300 is mounted on the carrier body 204, the first abutting portion 212 and the second abutting portion 305 are abutted against each other in the first direction Z to limit the relative positions of the conductive mounting member 300 and the carrier body 204 in the first direction Z. Among them, the portions of the first shielding member 207, the insulating member 206, and the second shielding member 208 protruding from the first abutting portion 212 are inserted into the accommodating groove 301.

[0069] Please refer to Figure 5 and Figure 6 .

[0070] In some embodiments, a grounding pin 213 is formed at the end of the first shielding member 207 in the first direction Z, and the grounding pin 213 is used for crimping to the circuit board. Among them, the grounding pin 213 is located between two adjacent pairs of signal pins 203 in the third direction Y.

[0071] The conductive mounting member 300 further has a second accommodating groove 306 and a second through hole 307. The second accommodating groove 306 opens in the reverse direction of the first direction Z, and the second through hole 307 is provided at the bottom of the second accommodating groove 306 and penetrates the conductive mounting member 300 in the first direction Z. The second accommodating groove 306 is located between two adjacent first accommodating grooves 301 in the third direction Y.

[0072] Among them, another part of the carrier body 204 is inserted into the second accommodating groove 306 in the first direction Z and abuts against the side wall surface of the second accommodating groove 306 to limit the conductive mounting member 300 from detaching from the carrier body 204, and the grounding pin 213 passes through the conductive mounting member 300 through the second through hole 307.

[0073] The connection structure between the carrier body 204 and the conductive mounting member 300 at the second accommodating groove 306 may refer to the connection structure at the accommodating groove 301, and details are not described herein again.

[0074] To make the grounding pin 213 and the signal pin 203 have the same height in the second direction X, the first shielding member 207 is provided with a bending structure at the grounding pin 213. Due to the bending structure, when the grounding pin 213 is crimped, the grounding pin 213 may move backward in the reverse direction of the first direction Z, and the positional accuracy of the grounding pin 213 is not easy to ensure. To solve this problem, the following improvements are also made.

[0075] See also Figure 8 and Figure 9 . Figure 9 yes Figure 4 CC section view in.

[0076] In some embodiments, the insulating member 206 has a first surface 214, a second surface 215, and a third surface 216 that are sequentially connected along the first direction Z and form a step shape. The first shielding member 207 includes a shielding body 209, a connecting portion 218, and a plug-in portion 219 that are sequentially connected along the first direction Z. The shielding body 209 covers and is fixedly disposed on the first surface 214. The connecting portion 218 is bent from the edge of the shielding body 209 and is disposed opposite to the second surface 215. The plug-in portion 219 is bent from the edge of the connecting portion 218 and is disposed opposite to the third surface 216. One end of the plug-in portion 219 that is away from the connecting portion 218 forms a ground pin 213. Among them, the conductive mounting member 300 presses the plug-in portion 219 against the third surface 216, and the plug-in portion 219 is concave-convexly matched with the insulating member 206 along the normal direction (second direction X) of the third surface 216.

[0077] Specifically, the third surface 216 has a protruding limiting protrusion 217, and the plug-in portion 219 has a notch 220 that matches the shape and size of the limiting protrusion 217. The plug-in portion 219 is sleeved outside the limiting protrusion 217 through the notch 220, thereby forming a limiting matching structure.

[0078] Specifically, the plug-in portion 219 has a protrusion 221 on the side facing away from the third surface 216 , and the protrusion 221 is located at the edge of the notch 220 . The conductive mounting member 300 abuts against the protrusion 221 , thereby pressing the plug-in portion 219 against the third surface 216 .

[0079] Specifically, the insulating member 206 is substantially in the shape of a plate, and the first shielding member 207 and the second shielding member 208 are respectively disposed on both sides of the thickness direction of the insulating member 206. The thickness of the insulating member 206 at the third surface 216 is thinner than that at the first surface 214, so that the plug-in portion 219 is offset toward the second shielding member 208 relative to the shielding body 209 in the normal direction of the third surface 216, thereby making the height of the ground pin 213 and the signal pin 203 in the second direction X consistent.

[0080] Specifically, the plug-in portion 219 has two ground pins 213 spaced apart along the third direction Y. The two ground pins 213 penetrate the conductive mounting member 300 through the second through holes 307 , respectively.

[0081] Specifically, the first shielding member 207 is integrally formed by stamping. A first bending angle is formed between the shielding body 209 and the connecting portion 218, and a second bending angle is formed between the connecting portion 218 and the inserting portion 219. Due to manufacturing errors of the first bending angle and the second bending angle, the position accuracy of the inserting portion 219 relative to the shielding body 209 is low. When the shielding body 209 is fixed to the insulating member 206, the position accuracy of the inserting portion 219 relative to the insulating member 206 is low.

[0082] In the embodiment of the present application, the conductive mounting member 300 presses the inserting portion 219 against the third surface 216, so that the degree of freedom of the inserting portion 219 in the normal direction of the third surface 216 is restricted. The inserting portion 219 and the insulating member 206 are in concave-convex fit along the normal direction of the third surface 216, so that the degree of freedom of the inserting portion 219 in any direction parallel to the third surface 216 is restricted. Thus, the position accuracy of the inserting portion 219 can be guaranteed.

[0083] In addition, in the embodiment of the present application, through the concave-convex fit between the inserting portion 219 and the insulating member 206 along the normal direction of the third surface 216, the inserting portion 219 is limited in the first direction Z, so that the ground pin 213 can be prevented from retracting during crimping.

[0084] The introduction provided in the above steps is only used to help understand the method, structure and core idea of the present application. For those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
