Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a plug-in module. Background Technology

[0002] With the development of 4G and 5G technologies, people's demands for the transmission rate of modern data communication transmission systems are increasing. As the core bridge of data communication, the SI performance of high-speed backplane connectors directly affects the transmission rate of modern data communication transmission systems. High-speed backplane connectors typically include a housing and several plug-in modules installed within the housing. Each plug-in module includes a plastic shell and multiple ground terminals and multiple signal terminals disposed within the shell. Each pair of adjacent signal terminals forms a differential signal pair, and each differential signal pair is distributed between corresponding adjacent two ground terminals.

[0003] Placing shielding plates between the plug-in modules of a high-speed backplane connector can effectively reduce crosstalk within the connector's internal circuitry. These shielding plates reduce electromagnetic coupling between signals, thereby significantly improving its signal integration (SI) performance to meet the demands of higher transmission rates. These shielding plates are typically positioned one-to-one on the same side of each plug-in module, for example, on the left or right side of each module, to shield against signal crosstalk from adjacent plug-in modules. Therefore, the structure of the shielding plates is crucial.

[0004] In related technologies, when setting the shielding plate, the shielding plate is connected to the corresponding side of the plastic shell of the plug-in module, and the shielding plate is in contact with the grounding terminal in the plastic shell of the corresponding plug-in module to achieve the grounding shielding function. However, this method makes it difficult to ensure that the shielding plate is always in contact with the grounding terminal. Utility Model Content

[0015] Furthermore, the shielding sheet is provided with long protruding ribs and short protruding ribs spaced apart along its length at the position corresponding to the grounding terminal, and the short protruding ribs are closer to the mating end direction of the grounding terminal and spaced apart from the long protruding ribs.

[0016] Each set of claws is configured with two claws, one of which is located on the shielding plate between the long rib and the short rib, and the other claw is located on the edge of the shielding plate near the mating end.

[0017] Each set of locking holes is configured with two holes, one of which is located on the grounding terminal corresponding to one of the locking claws, and the other is located on the grounding terminal corresponding to the other locking claw.

[0018] Furthermore, the plug-in module is configured as an L-shaped plug-in module. The plastic shell of the L-shaped plug-in module includes a split first shell and a second shell, with the second shell perpendicularly distributed on one side edge of the first shell. The grounding terminal and the signal terminal are distributed at intervals in the first shell and the second shell along a first direction. The mating ends of the grounding terminal and the signal terminal extend from the end of the first shell away from the second shell along a second direction.

First rivets are positioned on the plastic shell corresponding to the grounding terminal positions, and each first rivet is staggered from the others in the column direction of the grounding terminal, increasing multiple connection points and strengthening the connection strength between the plastic shell and the shielding sheet. Furthermore, the special distribution of the first rivets has been verified numerous times to ensure that this distribution does not affect the performance of the shielding sheet or reduce crosstalk prevention capabilities. Replacing the traditional discontinuous rib design with an integral rib that adapts to the length of a section of the grounding terminal embedded in the plastic shell reduces structural complexity and manufacturing difficulty, while simultaneously improving shielding and crosstalk prevention capabilities.

[0045] Several embodiments are shown below, illustrating the structure of the plug-in module in each embodiment.

[0046] Example 1

[0047] Please see Figure 1 and Figure 2The shown plug-in module 100 includes a plastic housing 110, a plurality of grounding terminals 12a and signal terminals 12b disposed in the plastic housing 110, a shielding sheet 130 disposed on the side of the plastic housing 110, and a claw-locking assembly 140 disposed between the shielding sheet 130 and the grounding terminals 12a. The claw-locking assembly 140 is used to lock the shielding sheet 130 and the grounding terminals 12a together. The grounding terminals 12a and signal terminals 12b (hereinafter collectively referred to as connection terminals 120) are spaced apart in the plastic housing 110 along a first direction, with one end extending out of the plastic housing 110 to form a mating end 100a and the other end extending out of the plastic housing 110 to form a mounting end 100b. Two adjacent signal terminals 12b form a set of differential signal pairs, and a set of differential signal pairs is distributed between each pair of adjacent grounding terminals 12a.

[0048] The plug-in module 100 can be configured in an L-shape. The plastic housing 110 of the plug-in module 100 includes a split first housing 11a and a second housing 11b. The first housing 11a is distributed along the plug-in direction (second direction), and the second housing 11b is distributed along an installation direction (third direction) perpendicular to the plug-in direction. For example, the first housing 11a is distributed vertically, and the second housing 11b is distributed horizontally. The connection terminals 120 are correspondingly configured as L-shaped connection terminals 120 accommodated in the first housing 11a and the second housing 11b. All connection terminals 120 are spaced apart in the first housing 11a and the second housing 11b along a first direction. The connecting terminal 120 has a first section 121 embedded in the first housing 11a, a second section 122 embedded in the second housing 11b, and a bent section 123 bent and connected between the first section 121 and the second section 122. The mating end 100a extends out of the first housing 11a from the end of the first section 121 away from the second section 122 along a second direction. The mounting end 100b extends out of the second housing 11b from the end of the second section 122 away from the first section 121 along a third direction.

[0049] A first groove 111 is provided on the plastic shell 110 at the position corresponding to each grounding terminal 12a. The first groove 111 is recessed from the side of the plastic shell 110 facing the shielding sheet 130 towards the side away from the shielding sheet 130. Each first groove 111 is distributed along the length direction of the corresponding grounding terminal 12a, and the length and distribution direction of each first groove 111 are adapted to the length and distribution direction of the section of the corresponding grounding terminal 12a embedded in the plastic shell 110. In this embodiment, both the first shell 11a and the second shell 11b are provided with a plurality of first grooves 111 distributed along the length direction of each grounding terminal 12a.

[0050] The first housing 11a is provided with a first rivet 112 at each position corresponding to a plurality of grounding terminals 12a (the number of the plurality of grounding terminals 12a is less than or equal to the total number of all grounding terminals 12a). The first rivet 112 is integrally formed at the position of the corresponding first groove 111, and each first rivet 112 is offset from the other first rivets 112 in the length direction of the grounding terminal 12a. The dimension of the first rivet 112 along the width direction of the grounding terminal 12a is greater than the dimension along the length direction of the grounding terminal 12a. A plurality of second rivets 113 may also be provided on the two side edges of the first housing 11a facing the first direction, and the plurality of second rivets 113 on each side edge are spaced apart along the insertion direction. Preferably, the cross-section of the plurality of first rivets 112 is elongated, such as elliptical. The second rivets 113 are configured as cylindrical rivets, and the second rivets 113 may be configured on the edge portion of the plastic housing 110 located outside the grounding terminal 12a and the signal terminal 12b.

[0051] The first rivet 112 and the second rivet 113 both protrude from the plastic shell 110 toward the shielding sheet 130, and their protrusion lengths from the plastic shell 110 are greater than the thickness of the shielding sheet 130 (i.e., the first rivet 112 protrudes from the first groove 111 toward the shielding sheet 130, and the protrusion length of the first rivet 112 is greater than the vertical distance from the first groove 111 to the side of the shielding sheet 130 facing away from the plastic shell 110; the second rivet 113 protrudes from the plastic shell 110 toward the shielding sheet 130, and the protrusion length of the second rivet 113 is greater than the thickness of the shielding sheet 130). Thus, when the shielding sheet 130 is attached to the plastic shell 110, the protruding ends (protruding ends) of the first rivet 112 and the second rivet 113 can be riveted to the side of the shielding sheet 130 facing away from the plastic shell 110 by processes such as hot pressing.

[0052] Please see Figure 3 The shielding sheet 130 is configured as an L-shaped shielding sheet 130 adapted to the L-shaped plastic shell 110. The shielding sheet 130 is integrally bent from a sheet metal and includes a first shielding sheet 13a attached to the outside of the first shell 11a and a second shielding sheet 13b integrally formed with the first shielding sheet 13a and attached to the outside of the second shell 11b. Both the first shielding sheet 13a and the second shielding sheet 13b are provided with a first protruding rib 131 that mates with the corresponding first groove 111. The first protruding rib 131 is integrally formed by a stamping process, stamped from the outer side of the shielding sheet 130 (the side facing away from the plastic shell 110) to the inner side of the shielding sheet 130 (the side facing the plastic shell 110). Therefore, the outer side of the shielding sheet 130 forms a second groove 132 that matches the shape of the first protruding rib 131. The dimension of the second groove 132 along the width direction of the grounding terminal 12a is smaller than the dimension in the corresponding direction of the first rivet 112. The number of the first protruding ribs 131, the distribution length and distribution direction of each first protruding rib 131 are adapted to the number of the first grooves 111, the distribution length and distribution direction of each first groove 111 (the number of the first protruding ribs 131 is less than or equal to the number of the first grooves 111), so that when the shielding sheet 130 is combined with the plastic shell 110, each first protruding rib 131 is inserted into the corresponding first groove 111 and tightly fitted therewith.

[0053] A first rivet hole 133 is provided on the shielding plate 130 at the position corresponding to each first rivet 112, through which the first rivet 112 passes. A second rivet hole 134 is provided on the shielding plate 130 at the position corresponding to each second rivet 113, through which the second rivet 113 passes and is riveted. When assembling the shielding sheet 130 and the plastic shell 110, firstly, the first rivet 112 and the second rivet 113 are aligned with the corresponding rivet holes, so that the first rib 131 of the shielding sheet 130 is inserted into the first groove 111, and the first rivet 112 and the second rivet 113 are respectively inserted into the corresponding first rivet hole 133 and the second rivet hole 134. The first rivet 112 and the second rivet 113 are riveted to the corresponding rivet holes. For example, a hot pressing process is used to hot press one end of the first rivet 112 and the second rivet 113 that protrudes from the shielding sheet 130 (the end away from the plastic shell 110), so that the outer circumferential dimension of this end is larger than the size of the corresponding rivet hole, to prevent the first rivet 112 and the second rivet 113 from coming off the corresponding rivet hole. Furthermore, since the protruding length of the first rivet 112 is greater than the vertical distance from the first groove 111 to the side of the shielding sheet 130 facing away from the plastic shell 110, and since the dimension of the first rivet 112 along the width direction of the grounding terminal 12a is greater than the dimension of the second groove 132, the first rivet 112 can be riveted to the portion of the shielding sheet 130 located outside the lateral sides of the second groove 132, rather than riveted to the bottom of the second groove 132, thus reducing the difficulty of the riveting process and improving the riveting efficiency.

[0054] Please see Figure 4To enhance the contact performance between the grounding terminal 12a and the shielding sheet 130 and ensure the contact stability between the shielding sheet 130 and the grounding terminal 12a, an elastic abutment component is provided between the shielding sheet 130 and each grounding terminal 12a to allow the grounding terminal 12a to elastically abut against the shielding sheet 130. The elastic abutment component may be defined as a plurality of elastic abutment members 124 spaced apart on the grounding terminal 12a. The elastic abutment members 124 are located on the side of the grounding terminal 12a facing the shielding sheet 130, and the elastic abutment members 124 pass through the plastic shell 110 and elastically abut against the grounding terminal 12a. Specifically, a second window 114 is provided on the side of the plastic shell 110 facing the shielding sheet 130 at the position opposite each elastic abutment 124. That is, a plurality of second windows 114 are provided on each first groove 111 along its length. The plurality of second windows 114 on each first groove 111 correspond one-to-one with a plurality of elastic abutments 124 on the corresponding grounding terminal 12a. The elastic abutment 124 passes through the second window 114 and elastically abuts against the shielding sheet 130. Specifically, the elastic abutment 124 can be integrally formed on the grounding terminal 12a at the position opposite the second window 114. For example, in the embodiment shown in the figure, a third window 125 is provided on each grounding terminal 12a at the position opposite the second window 114. The third window 125 and the elastic abutment 124 are both formed by a stamping process. The elastic support member 124 is connected to one side of the third window 125, and the other end extends obliquely toward the shielding sheet 130.

[0055] The claw fastener assembly 140 includes a claw 141 disposed on the shielding plate 130 and a corresponding latching hole 142 disposed on the grounding terminal 12a at the position corresponding to the claw 141; or, the claw fastener assembly 140 may also be configured to include a claw 141 disposed on the grounding terminal 12a and a corresponding latching hole 142 disposed on the shielding plate 130 at the position corresponding to the claw 141; or, the claw fastener assembly 140 may also be configured to include a claw 141 disposed on the shielding plate 130 and the grounding terminal 12a, a latching hole 142 disposed on the grounding terminal 12a at the position corresponding to the claw 141 on the shielding plate 130, and a latching hole 142 disposed on the shielding plate 130 at the position corresponding to the claw 141 on the grounding terminal 12a.

[0056] The number of sets of claws 141 and holes 142 corresponds to the number of all grounding terminals 12a. Each set of claws 141 includes at least one claw 141, and each set of holes 142 also includes at least one hole 142. The plastic shell 110 has a through hole (not shown) at the position corresponding to the claw fastener assembly 140 for the claws 141 to pass through.

[0057] The claw 141 can be configured to be integrally formed on the shielding sheet 130 and / or integrally formed on the grounding terminal 12a. Specifically, the shielding sheet 130 and / or the grounding terminal 12a may be provided with a first window 143 extending along its thickness direction. One end of the claw 141 is connected to one side of the first window 143, and the other end is bent and extended towards the plastic part, thereby passing through the perforation on the plastic shell 110 and engaging with the locking hole 142.

[0058] In this embodiment, each set of claws 141 and holes 142 is configured as one. Each claw 141 is located on the edge of the shielding plate 130 (first shielding plate 13a) facing the mating end 100a. Each hole 142 is located on the grounding terminal 12a (first section 121) at the position corresponding to the claw 141.

[0059] In summary, the plug-in module 100 of this embodiment can achieve at least the following functions and effects: The shielding sheet 130 is connected to each grounding terminal 12a via a claw-and-buckle assembly 140, increasing the connection strength between the shielding sheet 130 and the grounding terminal 12a, ensuring that the shielding sheet 130 remains connected to the grounding terminal 12a and guaranteeing shielding performance; First rivet posts 112 are arranged on the plastic shell 110 at positions corresponding to the grounding terminals 12a, and each first rivet post 112 is staggered from the other first rivet posts 112 in the column direction of the grounding terminals 12a, increasing multiple connection points and strengthening the connection strength between the plastic shell 110 and the shielding sheet 130. Furthermore, the special distribution of the first rivet posts 112 has been verified numerous times, proving that this distribution does not affect the performance of the shielding sheet 130 or reduce its anti-crosstalk capability. The traditional discontinuous rib design is replaced by an integral rib that matches the length of a section of the grounding terminal 12a embedded in the plastic shell 110. This reduces structural complexity and manufacturing difficulty, while also improving shielding and crosstalk prevention capabilities.

[0060] Example 2

[0061] Please see Figure 5 and Figure 6The plug-in module 200 shown includes a plastic shell 210, a connecting terminal 220, a shielding sheet 230, and an elastic abutment assembly, which have the same or similar structure or function as those in Embodiment 1. The difference between the plug-in module 200 of this embodiment and Embodiment 1 is that:

[0062] For each grounding terminal 22a, each set of claws 241 includes a plurality of claws 241, which are distributed at intervals along the second direction on the shielding sheet 230 at positions corresponding to the grounding terminal 22a; each set of holes 242 includes a plurality of holes 242, which are distributed at intervals along the second direction on the grounding terminal 22a.

[0063] In the illustrated embodiment, the plurality of claws 241 in each group are staggered on both sides (facing the first direction) along the length of the grounding terminal 22a. Specifically, a plurality of first windows 143 are provided on the shielding plate 230 (first shielding plate 23a) at positions corresponding to each grounding terminal 22a, and the plurality of first windows 243 are distributed at intervals on the shielding plate 230 along the length of the grounding terminal 22a. The first window 243 has a first side (left side) and a second side (right side) facing the first direction. A claw 241 is provided on the second side of the first first window 243 closest to the mating end 200a, a claw 241 is provided on the first side of the second first window 243 next to the mating end 200a (adjacent to the first first window 243), and so on, so that the plurality of claws 241 are alternately distributed on both sides. Correspondingly, the locking holes 242 on the grounding terminal 22a are provided one-to-one at the position of each claw 241. Preferably, a plurality of claws 241 are also provided on both sides of the shielding sheet 230 facing the first direction, and the claws 241 on both sides face the same direction.

[0064] Those skilled in the art will understand that the distribution direction of the claws 241 is not limited to the staggered distribution of this embodiment. For example, in some embodiments, each group of claws 241 is distributed on the same side (the same side of the first window 243) along the first direction. In other embodiments, one or more groups of claws 241 are distributed on the same side, while the remaining groups of claws 241 are staggered on both sides.

[0065] In this embodiment, the plug-in module 200 configures the claw fastener assembly 240 as a plurality of claws 241 that are staggered along the length direction of the grounding direction, which increases the number of connection points between the shielding sheet 230 and the grounding terminal 22a, and the staggered arrangement makes the connection between the shielding sheet 230 and the grounding terminal 22a more stable and reliable.

[0066] Example 3

[0067] Please see Figure 7 and Figure 8 The plug-in module 300 shown includes a plastic shell 310, a connecting terminal 320, a shielding sheet 330, and an elastic abutment assembly, which have the same or similar structure or function as those in Embodiment 1. The difference between the plug-in module 300 of this embodiment and Embodiment 1 is that:

[0068] The shielding sheet 330 (e.g., the first shielding sheet 33a) is provided with a long protruding rib 331 and a short protruding rib 332 at the position corresponding to each grounding terminal 32a. The long protruding rib 331 and the short protruding rib 332 are distributed at intervals along the length direction (second direction) of the grounding terminal 32a, and a gap space is formed between the long protruding rib 331 and the short protruding rib 332. The short protruding rib 332 is closer to the mating end 300a, and the long protruding rib 331 is closer to the mounting end 300b.

[0069] Both the long rib 331 and the short rib 332 are integrally formed by stamping. They are formed by stamping from the outer side of the shielding sheet 330 (the side facing away from the plastic shell 310) to the inner side of the shielding sheet 330 (the side facing the plastic shell 310). Therefore, the outer side of the shielding sheet 330 has a long groove 333 that matches the shape of the long rib 331 and a short groove 334 that matches the shape of the short rib 332.

[0070] In this embodiment, each set of latches 341 is configured in pairs. One latch 341 is located on the shielding plate 330 between the long protruding rib 331 and the short protruding rib 332, and the other latch 341 is located on the shielding plate 330 near the mating end 300a. Each set of locking holes 342 is configured in pairs. One locking hole 342 is located on the grounding terminal 32a corresponding to one of the latches 341, and the other locking hole 342 is located on the grounding terminal 32a corresponding to the other latch 341.

[0071] Example 4

[0072] Please see Figure 9 and Figure 10 The plug-in module 400 shown includes a plastic shell 410, a connecting terminal 420, a shielding sheet 430, and an elastic abutment assembly, which have the same or similar structure or function as those in Embodiment 1. The difference between the plug-in module 400 of this embodiment and Embodiment 1 is that:

[0073] The lengths of the first housing 41a and the second housing 41b are both distributed along the first direction, and the widths of the first housing 41a and the second housing 41b are both distributed along the second direction. Therefore, the first housing 41a and the second housing 41b are both flat and elongated rectangular block structures, and their dimensions in the length direction (second direction) of the connecting terminal 420 are both small.

[0074] The shielding sheet 430 is configured to be disposed on the first housing 41a and near the mating end 100a. The dimension of the shielding sheet 430 along the second direction is smaller than the dimension of the first housing 41a in the corresponding direction. The shielding sheet 430 is provided with a second protruding rib 431 for contacting the grounding terminal 42a at the position corresponding to each grounding terminal 42a. The second protruding rib 431 is integrally formed by stamping process, and is formed by stamping from the outer side of the shielding sheet 430 (the side facing away from the plastic housing 410) to the inner side of the shielding sheet 430 (the side facing the plastic housing 410). Therefore, the outer side of the shielding sheet 430 forms a third groove 432 that matches the shape of the second protruding rib 431.

[0075] In the embodiment shown, each set of claws 441 and holes 442 is configured in pairs. The two claws 441 are respectively disposed on the two sides of the shielding plate 430 facing the second direction, and the two holes 442 are disposed on the grounding terminal 42a at positions corresponding to the two claws 441.

[0076] Example 5

[0077] Please see Figure 11 The plug-in module 500 shown includes a plastic shell 510, a connecting terminal 520, a shielding sheet 530, and an elastic abutment assembly, which have the same or similar structure or function as those in Embodiment 1. The difference between the plug-in module 500 of this embodiment and Embodiment 1 is that:

[0078] The plastic shell 510 is configured as a rectangular sheet structure or a near-rectangular sheet structure, and the shielding sheet 530 is also configured as a rectangular sheet structure or a near-rectangular sheet structure adapted to the plastic shell 510. The mating end 500a of the connecting terminal 520 extends out of the plastic shell 510 along a second direction, and the mounting end 100b extends out of the plastic shell 510 along a first direction. Each connecting terminal 520 is embedded in a portion of the plastic shell 510, which is configured as a curved segment (not shown in the figure), with both ends of the curved segment facing the second direction and the first direction, respectively. It should be understood that the portion of the connecting terminal 520 embedded in the plastic shell 510 is not limited to the aforementioned curved shape. For example, when the plug-in module 500 is applied in a linear electrical connector, the connecting terminal 520 is entirely linear, and its portion embedded in the plastic shell 510 is also a linear segment.

[0079] In the illustrated embodiment, the claw 541 is disposed at the grounding terminal 52a, and the locking hole 542 is disposed at the shielding plate 530. That is, each grounding terminal 52a is provided with at least one claw 541, the claw 541 is bent and extends toward the shielding plate 530; the locking hole 542 is provided at the shielding plate 530 corresponding to the position of the claw 541.

[0080] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
