Description

Technical Field

[0001] This utility model relates to components of conductive connection devices, and more particularly to connector chips and connectors. Background Technology

[0002] With the rapid development of communication technology, high-speed connectors used on printed circuit boards have increasingly higher requirements for transmission rate and transmission quality. Chinese invention patent CN113612081B discloses a sub-connector and a chip. The chip includes an insulating body, within which a pair of differential pins are fixed. The two ends of the differential pins extend from the two sides of the insulating body, respectively forming a fisheye end and a mating end. Shielding plates are mounted on the two side plates of the insulating body to shield the differential pins within the insulating body. Specifically, the shielding plates protrude and extend from the edge of the insulating body where the mating end is located, placing the mating end in the mating space between the extended portions of the two shielding plates. A shielding support plate is also installed between adjacent pairs of differential pins in this mating space. The shielding support plate and the two shielding plates form a mating cavity extending along the mating direction, allowing the shielding sleeve of the adapter connector to be inserted. The shielding sleeve of the adapter connector makes conductive contact with both the shielding plates and the shielding support plate, thereby achieving grounding conductivity between the two connectors.

[0003] The aforementioned connector chip has a shielding support plate that is interference-fitted onto the insulating body at the rear end. The upper and lower sides of the shielding support plate are fixedly connected to the corresponding shielding sheet by welding, thereby achieving the fixed installation of the shielding support plate. However, this installation method requires a large investment in welding equipment and has a high cost. Moreover, the welding surface between the shielding support plate and the shielding sheet is relatively narrow, making welding difficult and resulting in poor processability. Utility Model Content

[0069] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0070] This invention improves the chip structure of existing connectors, especially optimizing the fixing method between the chip's shielding sheet and the shielding support plate. The two are assembled by insertion, replacing the welding method used in the prior art. This solves the problem caused by welding between the upper and lower edges of the shielding support plate and the two adjacent shielding sheets in the prior art.

[0071] The specific implementation of the connector of this utility model is as follows: Figure 1-25 As shown. The connector includes an assembly housing and connector chips 1. Multiple connector chips 1 are stacked in the thickness direction and then fixedly assembled by the assembly housing to form an integral structure for mating with the adapter connector and connecting to the printed circuit board. For ease of accurate explanation, the thickness direction of the connector chip 1 is defined as the vertical direction, and the side of the connector chip 1 facing the adapter connector is defined as the front side.

[0072] like Figure 1-5 As shown, the connector chip 1 includes a plate-shaped insulating body 12 and shielding plates 13 mounted on both sides of the insulating body 12. A pair of differential pins are fixed inside the insulating body 12, with both ends extending from the edges of the insulating body 12. One end is a differential pin fisheye end 10 for connecting to the printed circuit board, and the other end is a plug-in end for plugging into the differential pins of the adapter connector. Shielding plate mounting slots 120 are provided on both sides of the insulating body 12. The shielding plate 13 is mounted within the mounting slots 120. A mounting protrusion 121 is provided on the insulating body 12 within the mounting slots 120, and a mounting hole corresponding to the mounting protrusion 121 is provided on the shielding plate 13. When the shielding plate 13 is mounted into the mounting slots 120, the mounting protrusion 121 is inserted into the mounting hole. The interference fit between the two achieves the fixed mounting of the shielding plate 13 on the side of the insulating body 12.

[0073] The assembly housing includes a snap-fit ​​fastener, a positioning plate 3, and an insertion housing. Multiple connector chips 1 are stacked together and secured together by the snap-fit ​​fastener to prevent them from separating. The positioning plate 3 is fastened to the sides of all insulating bodies 12 from the differential pin fisheye end 10. The assembly formed by the multiple connector chips 1, the snap-fit ​​fastener, and the positioning plate 3 is inserted into the insertion housing. The assembly method between the multiple connector chips 1, the snap-fit ​​fastener, and the positioning plate 3 is the same as in the prior art and will not be described further here.

[0074] The structure of the insert housing is as follows Figure 21-25As shown, a shell-like structure with an opening on one side includes four surrounding walls and end plates perpendicular to the four surrounding walls. Its inner cavity is a wafer insertion cavity 40. Two opposite surrounding walls are provided with wafer insertion slots 400, and the edges of each wafer slide into the wafer insertion cavity 400 along the wafer insertion slots 400. The end plates are grid end plates 6, with grid holes 60 corresponding to the insertion ends of the differential pins of the wafer, allowing adapter connectors to be inserted to achieve connection and conduction between the two connectors.

[0075] like Figure 3-5 As shown, the shielding plate 13 of the connector chip 1 has a shielding plate overhang section 131 protruding from the edge of the insulating body 12 on the side where the plug end is located. The plug end of the differential pin extends into the mating space formed between the two shielding plate overhang sections 131 on the upper and lower sides of the insulating body 12. In this mating space, shielding support plates 5 are provided on both sides of each pair of differential pin plug ends 101 to achieve shielding of adjacent pairs of differential pins at the mating position. The two adjacent shielding support plates 5 and the shielding plates 13 on the upper and lower sides together form a rectangular cavity. This rectangular cavity is a plugging cavity for inserting a differential pair of the adapter connector and the rectangular shielding cylinder surrounding it. The differential pairs of the two connectors are plugged into each other, and the shielding cylinder of the adapter connector makes conductive contact with the cavity wall of the plugging cavity to achieve grounding. The upper and lower shielding plates 13 have shielding plate fisheye ends 11 on one side edge corresponding to the fisheye ends 10 of the differential pins. The shielding plate fisheye ends 11 are located on the left and right sides of the fisheye ends 10 of two adjacent pairs of differential pins, and shield the two adjacent pairs of differential pins at the position where they are connected to the printed circuit board. The specific structure is similar to that of the prior art.

[0076] The shielding support plate 5 is fixedly assembled at a specific position in the insertion space by inserting and fixing the upper and lower edges of the shielding support plate 5 with the two shielding plates 13 on the upper and lower sides in the vertical direction. Thus, when the shielding plates 13 on the upper and lower sides are snapped onto the insulating body 12, the shielding support plate 5 is simultaneously installed between the two shielding plates 13.

[0077] Specifically, such as Figure 6-15Each of the upper and lower shielding plates 13 has a shielding plate 13 insertion structure at a position corresponding to the shielding support plate 5. The shielding plate 13 insertion structure includes a limiting slot spaced apart front to back, with the limiting slot opening towards the other shielding plate 13. The limiting slot allows the shielding support plate 5 to be inserted vertically and clamped from both sides at its front and rear ends, thus limiting the shielding support plate 5 in the lateral direction. In the embodiment shown, the shielding plate 13 has a pair of latches 132 punched out, extending towards the shielding support plate 5. The pair of latches 132 cooperate to form the limiting slot. In other embodiments, the shielding plate 13 may also have a pair of protrusions punched on it, the protrusions being rectangular, with the recess between the two protrusions forming the limiting slot. Alternatively, in other embodiments, a U-shaped clip may be welded onto the shielding plate 13, the space inside the U-shaped clip forming the limiting slot.

[0078] In the embodiment shown in the figure, there are two limiting slots, one in front of the other, for insertion into the vicinity of the front and rear ends of the shielding support plate 5. Of course, the present invention is not limited to this embodiment. In other embodiments, there may be one limiting slot corresponding to the middle position of the shielding support plate 5, or there may be multiple limiting slots, arranged at intervals along the front and rear direction of the shielding support plate 5.

[0079] Furthermore, the shielding sheet 13 is provided with an insertion protrusion extending toward the shielding support plate 5. The edge of the shielding support plate 5 is provided with an insertion slot corresponding to the insertion protrusion. The two shielding sheets 13 are interlocked and the insertion protrusion is inserted into the insertion slot, thereby achieving the insertion and fixation of the two. Specifically, the insertion protrusion is a folded protrusion 133 formed by punching on the shielding sheet 13. The folded protrusion 133 on the shielding sheet 13 is folded toward the other shielding sheet 13. The folded protrusion 133 extends along the front-back direction and protrudes from the surface of the shielding sheet 13. In order to improve the insertion reliability between the insertion protrusion and the insertion slot, this embodiment provides a more optimized design, that is, the insertion protrusion is provided with a forced fitting protrusion 134, which is used to forcefully fit with the inner wall of the insertion slot.

[0080] The structure of the shielding support plate 5 is as follows: Figure 10-12 As shown, the shielding support plate 5 has a sandwich structure, comprising two single-sided plates 50. The two layers of the sandwich shielding support plate 5 are arranged side-by-side in the left-right direction and extend front-back. The central sandwich space 51 between the two layers forms an insertion slot for the folding protrusion 133 to be inserted. During manufacturing, the shielding support plate 5 is punched and stamped from a single sheet, and then the resulting elongated semi-finished product is folded in half from the middle to form the sandwich structure shielding support plate 5. This manufacturing method has a lower cost, and the central sandwich space 51 has a larger length in the front-back direction, which can accommodate positional deviations of the insertion protrusion in the front-back direction.

[0081] As shown in the figure, the front end of the shielding support plate 5 is a folded section. The rear side of the folding rib at the front end forms inclined sections that are far apart from each other, that is, the front end of the shielding support plate 5 is V-shaped. The rear end of the inclined section forms a straight section that extends backward. The insertion protrusion is inserted into the middle interlayer space 51 between the two straight sections. The inner edges of the upper and lower edges of the two straight sections are respectively provided with chamfers, so that the insertion slot formed between them is a flared slot, so that the folding protrusion 133 can be inserted.

[0082] The limiting slots correspond to the front and rear ends of the straight sections. To prevent the two straight sections from deforming and moving closer together due to material properties under clamping force, thus ensuring a secure clamping constraint between the limiting slots and the shielding support plate 5, the shielding support plate 5 has interlayer support structures at both its front and rear ends. The limiting slots are positioned close to these interlayer support structures. These structures provide support between the two layers of the shielding support plate 5, preventing them from moving closer together and ensuring the reliability of the clamping constraint. Figure 11 In the illustrated embodiment, the interlayer central support structure includes support protrusions 53 stamped on both sides of the shielding support plate 5. The two support protrusions 53 protrude towards each other and their top surfaces abut against each other, supporting the two side plates. In other embodiments, a support protrusion 53 can be provided on one of the two side plates of the shielding support plate 5, increasing its protrusion height so that it directly abuts against the surface of the other side plate, thus achieving the same supporting function. These embodiments all involve forming the interlayer central support structure without adding any components. In some other embodiments, a support pad can be sandwiched between the two layers of the shielding support plate 5 to form the interlayer central support structure. Of course, an implementation without a interlayer central support structure is also a feasible approach.

[0083] The rear ends of the two straight sections narrow in the width direction (vertical direction) and come close to each other to form the insertion tail section 55. The insertion tail section 55 is used to insert into the support plate insertion groove 122 opened at the edge of the insulating body 12 to realize the fixed installation between the rear end of the shielding support plate 5 and the insulating body 12. Figure 9The structure of the support plate insertion slot 122 on the insulating main board is shown. The edge of the insulating body 12 is provided with a support plate insertion slot 122 that penetrates through the insulating body 12 in the thickness direction for the rear end of the shielding support plate 5 to be inserted. It can be seen that the support plate insertion slot 122 is not a normal rectangular slot with the opening facing forward. Instead, a pair of forced mounting protrusions 124 are provided at the front end near the opening and at the rear end near the bottom of the slot, respectively. After the insertion tail section 55 is inserted into the support plate insertion slot 122, it is clamped tightly with the forced mounting protrusions 124, thereby ensuring the insertion reliability between the shielding support plate 5 and the insulating body 12. Of course, the implementation method of directly forcing the insertion tail section 55 into the slot wall without setting the forced mounting protrusions 124 is also a feasible method. In order to facilitate the insertion of the insertion tail section 55 into the support plate insertion slot 122, the front end of the pair of forced mounting protrusions 134 is provided with a guide surface 125. The guide surfaces 125 on the two forced mounting protrusions 124 together form a flared structure.

[0084] The shielding support plate 5 is inserted into the support plate insertion slot 122 via an insertion tail section 55 on one vertical surface, which can ensure positional accuracy in the left and right directions. However, whether the shielding support plate 5 can extend straight back and forth cannot be guaranteed at the rear end position of the shielding support plate 5. Therefore, the groove edge of the support plate insertion slot 122 on at least one side of the insulating body 12 is recessed to form a surface positioning groove 123. The rear end of the shielding support plate 5 is folded to form a folded positioning wing plate 56 extending along the surface of the insulating body 12. After the insertion tail section 55 is inserted into the support plate insertion slot 122, the folded positioning wing plate 56 is inserted into the surface positioning groove 123 from front to back, and the plate surface of the folded positioning wing plate 56 is in contact with the bottom of the surface positioning groove 123 to prevent the shielding support plate 5 from deviating in the thickness direction of the insulating body 12. As shown in the figure, both layers of the sandwich-structured shielding support plate 5 have folding positioning wing plates 56 on their insert tail sections 55. The upper and lower edges of the insert tail section 55 are folded to form the folding positioning wing plates 56. This effectively ensures high positioning accuracy and retention between the insert tail section 55 and the support plate insert groove 122, thereby improving the installation accuracy of the shielding support plate 5. Of course, the number of folding positioning wing plates 56 and the arrangement of the surface positioning grooves 123 can vary in different embodiments. For example, if one side of the shielding support plate 5 of the sandwich structure has a folding positioning wing plate 56 on its insertion tail section 55, while the other side does not have a folding positioning wing plate 56, and there is only one folding positioning wing plate 56, then the insulating body 12 only has surface positioning grooves 123 on one side of both the upper and lower sides. If there are two folding positioning plates 3 and they are opposite each other, then the upper and lower sides of the insulating body 12 will both have surface positioning grooves 123 at positions corresponding to the folding positioning wing plate 56. Alternatively, the shielding support plate 5 of the sandwich structure may have a folding positioning wing plate 56 on each side of its insertion tail section 55, with the two folding positioning wing plates 56 on the same plane or one at a higher position than the other.

[0085] The shielding support plate 5 is provided with contact springs 52 protruding to the left and right sides. The contact springs 52 are used to elastically abut against the sides of the shielding cylinder of the adapter connector to achieve grounding and conduction. The contact springs 52 on the left and right sides are respectively set on the two side plates of the shielding support plate 5 of the sandwich structure, and are formed by punching and stamping. The contact springs 52 are located between the front and rear limiting slots, and also between the middle support structures of the front and rear sandwich structures.

[0086] The structure of the insert housing is as follows Figure 21-25 As shown, the structure formed by multiple connector chips 1, mounting fasteners, and positioning plates 3 is inserted into the insertion housing. Figure 1As shown in Figures 16-20, the insertion housing includes four walls (upper, lower, left, and right) and a front-end plate connected to the front ends of the four walls. The front-end plate is a grid end plate 6, which has grid holes 60 at positions corresponding to each insertion cavity to prevent the insertion of the adapter connector. The rear ends of the left and right walls protrude rearward from the upper and lower walls, and each of the left and right walls has a chip insertion slot 400 for each chip to slide into the insertion housing along the chip insertion slot 400. The front ends of the left and right walls protrude and extend with guide keys 41 to cooperate with guide slots on the adapter connector housing to achieve accurate mating of the two connectors.

[0087] The grid hole 60 is a rectangular hole. The grid frame 63 surrounding the grid hole 60 includes a longitudinal grid frame 63 extending left and right and a transverse grid frame 63 extending up and down. The longitudinal grid frame 63 has a longitudinally extending longitudinal reinforcing rib 64 at the rear center, and the transverse grid frame 63 has a transversely extending transverse reinforcing block 61 at the rear. The transverse reinforcing blocks 61 on the same transverse grid frame 63 are arranged in pairs, forming a support plate positioning groove 62. The front end of the shielding support plate 5 is flattened to form a guide end 54 extending up and down. The guide end 54 can be inserted into the support plate positioning groove 62 to limit and position the shielding support plate 5 and enhance the positional accuracy and strength of the shielding support plate 5. To facilitate the entry of the guide end 54, the inner side of the transverse reinforcing block 61 has opposite inclined surfaces, and the support plate positioning groove 62 forms a flared structure. The transverse reinforcing block 61 is positioned close to the longitudinal reinforcing rib 64, and the gap between the transverse reinforcing block 61 and the longitudinal reinforcing rib 64 forms a limiting groove for the shielding plate 13. Figure 20 As shown, the front end of the shielding sheet 13 extends into the shielding sheet 13 limiting groove. The shielding sheet 13 limiting groove limits and reinforces the shielding sheet 13 to prevent large deformation and displacement of the shielding sheet 13 after installation.

[0088] In the above embodiments, the shielding sheet 13 insertion structure includes a limiting slot formed by a pair of latches 132 and an insertion protrusion formed by a folding protrusion 133. In other embodiments, the shielding sheet 13 insertion structure may only include the limiting slot. In this case, the shielding support plate 5 may be a single-layer structure, and the contact springs 52 on the left and right sides may be formed by punching and stamping on the single-layer support plate. The front end of the single-layer support plate constitutes the guide end 54, and the rear end serves as the insertion tail section 55. Alternatively, in another embodiment, the shielding sheet 13 insertion structure may only include the folding protrusion 133.

[0089] In the above embodiments, the shielding support plate 5 is a sandwich structure, and the middle sandwich space 51 of the sandwich structure forms an insertion slot. In other embodiments, the shielding support plate 5 is a single-layer plate, and an arched section protruding to one side is punched at the edge of the single-layer plate. An insertion hole is formed between the arched section and the surface of the single-layer plate, which serves as an insertion slot for the folding protrusion 133 to be inserted.

[0090] In the above embodiments, the shielding sheet 13 insertion structure provided on the shielding sheet 13 is a protruding structure extending toward the shielding support plate 5. In other embodiments, punching holes can be provided on the shielding sheet 13, and protruding extension ears can be provided on the upper and lower edges of the shielding support plate 5. The extension ears are inserted into the punching holes on the shielding sheet 13, thereby realizing the insertion and fixing of the two.

[0091] In the above embodiments, the shielding support plate 5 of the sandwich structure is folded in half at the front. In other embodiments, it can also be folded in half at the rear end, that is, at the rear end position of the insert tail section 55, while the front ends of the two single-layer plates are brought together and flattened to form the guide end 54.

[0092] The specific implementation of the connector chip of this utility model has the same structure as the connector chip structure in the connector embodiments described above, and will not be repeated here.

[0093] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
