Description

Technical Field

[0001] This utility model belongs to the field of connection devices, and in particular relates to a shielding support, shielding structure and connector. Background Technology

[0002] Terminal modules are an important component of high-speed connectors. A terminal module generally includes an insulator, signal terminals integrally injection molded onto the insulator, and shielding plates that are secondary heat-riveted to both sides of the insulator. The signal terminals are arranged in differential pairs. The front end of the shielding plate extends out of the insulator to provide more comprehensive shielding for the signal terminals. A shielding support needs to be fixedly connected between the front overhangs of the two shielding plates to improve the deformation resistance of the shielding plates and enable the two shielding plates to conduct electricity.

[0003] The existing Chinese utility model patent with authorization announcement number CN215645331U discloses a bent male connector. In this bent male connector, a shielding support (i.e., the shielding plate connecting conductor in the patent) is also provided between the two shielding plates. The support plate is located between two adjacent differential pairs. The shielding plates are provided with positioning holes, and the support plate is provided with positioning protrusions that can be inserted into the positioning holes.

[0004] To ensure a reliable connection between the shielding support and the shielding sheet, they are typically welded together, with the welding point located at the mating position of the positioning protrusion and the positioning hole. For ease of assembly, the positioning protrusion and the hole wall have a certain clearance. If laser welding is used, the molten metal from the positioning protrusion must fill this clearance to reliably connect the protrusion and the hole wall, resulting in low welding efficiency. Furthermore, the molten metal is not well constrained and easily flows along the gap to other locations, affecting the weld quality. Utility Model Content

[0050] The present invention will be further described in detail below with reference to the embodiments.

[0051] Specific embodiment 1 of the connector provided by this utility model:

[0052] See appendix Figure 1 Appendix Figure 2 and attached Figure 3 The connector includes an insulating shell 5 and several terminal modules mounted on the insulating shell 5. In this invention, the direction of insertion and removal of the connector and the adapter connector is taken as the front-back direction, and the end of the connector that mates with the adapter connector is its front end. The direction in which each terminal module is arranged is transverse, and the direction perpendicular to both the front-back direction and the transverse direction is longitudinal.

[0053] See appendix Figure 4 and attached Figure 5 The terminal module includes an insulator 1, signal terminals and a shielding structure. The signal terminals are arranged in the form of differential pairs 2 and are integrally set on the insulator 1 by one injection molding. The shielding structure is fixedly connected to the insulator 1 by a secondary hot riveting method.

[0054] The shielding structure includes two shielding plates 3, which are respectively disposed on both sides of the insulator 1 in the transverse direction. See Appendix. Figure 6 The shielding plate 3 has perforations for the plastic post on the insulator 1 to pass through. After the two shielding plates 3 are installed, they can be fixed to the insulator 1 by heat riveting. The front end of the shielding plate 3 protrudes from the insulator 1 to provide shielding for the insertion end of the differential pair 2. The shielding structure also includes a shielding support 4 to provide support for the part of the shielding plate 3 that protrudes from the insulator 1. The shielding support 4 is installed after the two shielding plates 3 are assembled.

[0055] The shielding support 4 is disposed between the portions of the two shielding plates 3 that extend out of the insulator 1, and there are multiple shielding support members 4. On the one hand, the shielding support member 4 provides support for the two shielding plates 3 to prevent deformation of the shielding plates 3. On the other hand, it can also divide the space between the two shielding plates 3 into multiple shielding cavities for accommodating the plug-in ends of the differential pair 2.

[0056] In other embodiments, the shielding structure on a single terminal module may also include only a shielding sheet and several shielding supports. The shielding supports are disposed between the shielding sheet of the terminal module and the shielding supports of the adjacent terminal modules, and divide the space between the shielding sheets of the two terminal modules into multiple shielding cavities.

[0057] See appendix Figure 7 Appendix Figure 8 Appendix Figure 9 and appendix Figure 10Each shielding support 4 includes two support plates 41, which are closely attached along the direction and have their four edges aligned. The front ends of the two support plates 41 are integrally connected by a folding structure. During processing, the sheet metal is first punched into two coplanar support plates 41 according to the required shape. Then, the joint of the two support plates 41 is bent, so that the two support plates 41 are tightly attached together after being folded, and the folded position forms a folding structure.

[0058] After the two support plates 41 are folded in half, they need to be flattened at the folded front end to form a guide structure 42 that is flatter at the front and wider towards the back. Additionally, after the two support plates 41 are folded in half, pressure needs to be applied from their opposite sides to compress them. This is done to force the burrs at the edges of the support plates 41 to deform, thus ensuring that the two support plates 41 fit tightly together.

[0059] Both support plates 41 are formed with grounding springs 43 for contacting and conducting with the grounding element on the adapter connector, and the grounding springs 43 on the two support plates 41 are staggered in the lateral direction. The support plates 41 are provided with clearance space for avoiding the grounding springs 43 on the other support plate 41.

[0060] After the shielding support 4 is inserted between the two shielding sheets 3, the thickness direction of the support plate 41 is in the same direction as the longitudinal direction. The rear ends of the two support plates 41 are simultaneously inserted into the slots 11 at the front end of the insulator 1. The part of the support plate 41 used to insert into the slots 11 constitutes the insertion part 44. The two sides of the insertion part 44 are integrally and vertically provided with retaining parts 45 by bending. After assembly, the two retaining parts 45 on the same support plate 41 hold the two sides of the insulator 1 respectively to keep the posture of the support plate 41 stable.

[0061] See appendix Figure 11 The insulator 1 has corresponding receiving grooves 12 on its lateral sides for accommodating the retaining part 45. These grooves 12 and the shielding sheet 3 form a space for the retaining part 45 to be inserted. The slot 11 has barbed structures on both longitudinal side walls. These barbed structures are interference-fitted with the insertion part 44 on the support plate 41, ensuring stable insertion of the support plate 41 and preventing accidental dislodgement during assembly. Since the barbed structures are interference-fitted with the insertion part 44, to reduce assembly resistance and facilitate proper assembly, the retaining part 45 in this embodiment is clearance-fitted with the insulator 1, serving only to maintain the posture of the support plate 41.

[0062] The end faces of the two lateral edges of the support plate 41 abut against the inner surfaces of the corresponding shielding sheets 3 to provide good support for the shielding sheets 3. To ensure accurate installation of the support plate 41, the shielding sheets 3 are provided with positioning holes 31, and the support plate 41 is provided with positioning protrusions 46 that can be inserted into the positioning holes 31 to position the support plate 41 in the front-back direction and longitudinal direction.

[0063] Positioning protrusions 46 are correspondingly provided on the two support plates 41, and see attached figure. Figure 12 The corresponding positioning protrusions 46 on the two support plates 41 can be inserted into the same positioning hole 31, and the width of the positioning hole 31 is equal to twice the thickness of the positioning protrusion 46. The corresponding positioning protrusions 46 on the two support plates 41 are staggered in the front-back direction and are arranged adjacent to each other, and the length of the positioning hole 31 is equal to twice the length of the positioning protrusion 46.

[0064] The corresponding positioning protrusions 46 on the two support plates 41 are staggered in the front-to-back direction because: during the punching process, burrs inevitably appear on the edges of the support plates 41. These burrs are usually ground after punching, but due to the small size of the support plates 41, some burrs may not be completely removed. If burrs are present on the support plates 41, they will press against the space between the two support plates 41 after folding, causing a gap. Therefore, the two support plates 41 need to be compressed to eliminate the gap. The positioning protrusions 46 are even smaller, making it difficult to completely remove burrs from them during grinding. If a gap exists between the two positioning protrusions 46 in the longitudinal direction, it will increase the resistance to inserting the positioning protrusions 46 into the positioning holes 31, increasing the assembly difficulty. In this invention, the two positioning protrusions 46 are staggered along the front-back direction, which can effectively prevent burrs on the positioning protrusions 46 from pressing against the two positioning protrusions 46, thereby preventing gaps between the two positioning protrusions 46 in the longitudinal direction and ensuring ease of assembly.

[0065] During assembly, each positioning protrusion 46 contacts only one side of the longitudinal wall of the positioning hole 31. This creates a cantilever structure, allowing for elastic deformation towards the other support plate 41 as needed, further reducing assembly difficulty. The positioning protrusion 46 has a chamfered edge on the side facing away from the other support plate 41 to facilitate insertion into the positioning hole 31.

[0066] Two support plates 41 are joined at their end faces to form a welding support surface 47 for contacting and mating with the same shielding sheet 3. The shielding sheet 3 has welding holes 32 at corresponding positions to expose the welding support surface 47 for welding. The welding is specifically laser welding, with the laser spot size slightly larger than the welding hole 32. During welding, the sidewalls of the welding hole 32 and the exposed portion of the welding support surface 47 melt, thereby fusing the materials of the support plates 41 and the shielding sheet 3 together to form a reliable conductive and mechanical connection. During welding, not only can the support plates 41 and the shielding sheet 3 be fixed together, but the two support plates 41 can also be fixed together with each other.

[0067] Since the welding support surface 47 is formed by splicing the end faces of two support plates 41, the welding support surface 47 has sufficient width for welding, thus avoiding the problem of welding heat flow penetrating the support plate 41 and affecting the welding quality when welding a single thin support plate 41.

[0068] If a single-layer, thicker support plate 41 is used instead of the double-layer, thinner support plate 41 in this invention for welding, although a larger welding support surface 47 can be obtained, the following problems exist:

[0069] Firstly, the relatively thick single-layer support plate 41 is more difficult to process, requiring higher demands on the stamping equipment, which will increase the overall cost of the product.

[0070] Secondly, after the grounding spring 43 is processed from the single-layer thick support plate 41, the grounding spring 43 is also thick, making it more difficult to undergo elastic deformation. This increases the difficulty of mating with the adapter connector during use, and may even cause the problem of not being able to mat with the adapter connector.

[0071] Finally, during the punching process, the end face of the support plate 41 is not strictly perpendicular to its two sides in the thickness direction. Instead, it will have a certain angle due to material deformation. This angle will cause a height difference between the edges of the two sides of the support plate 41 in the thickness direction, preventing them from being completely aligned. If a single-layer, thicker support plate 41 is used, the height difference at the edges of the two sides of the support plate 41 in the thickness direction caused by this angle will be more obvious. During the welding process, the gap between the end face of the support plate 41 and the inner side of the shielding plate 3 will be larger, affecting the welding quality. However, when a double-layer, thinner support plate 41 is used, the height difference at the edges of the two sides of the support plate 41 in the thickness direction will be smaller. Therefore, the gap between the end face of the support plate 41 and the inner side of the shielding plate 3 can be reduced, which is beneficial to improving the welding quality.

[0072] In addition, welding holes 32 are also provided on the shielding plate 3 at the position corresponding to the holding part 45. Since the holding part 45 has a large contact area with the shielding plate 3, it can also ensure a good welding effect between the shielding support 4 and the shielding plate 3.

[0073] The insulating shell 5 has an open rear end, allowing the front ends of each terminal module to be inserted into the insulating shell 5 through the open end. A snap-fit ​​structure is provided between the insulating shell 5 and the terminal modules to ensure a stable assembly connection between each terminal module and the insulating shell 5.

[0074] See appendix Figure 13 A rearwardly protruding reinforcing block 51 is provided on the rearward inner surface of the insulating shell 5 to strengthen the structure of the insulating shell 5. The lateral dimension of the reinforcing block 51 is smaller than the distance between the front ends of the two shielding plates 3 in the same terminal module, so that it can be inserted between the two shielding plates 3 during assembly. A fixing groove 52 is provided on the rear end face of the reinforcing block 51. During assembly, the front end of the shielding support 4 can be inserted into the fixing groove 52, thereby using the fixing groove 52 to position the shielding support 4 and improve the deformation resistance of the shielding support 4. The guide structure 42 at the front end of the shielding support 4 facilitates the insertion of the shielding support 4 into the fixing groove 52. To further reduce the assembly difficulty, a chamfer is provided at the opening of the fixing groove 52 for guiding assembly.

[0075] See appendix Figure 14 The inner rearward side of the insulating shell 5 is also provided with a rearwardly protruding reinforcing rib 53, which extends longitudinally. During assembly, the reinforcing rib 53 can be inserted between adjacent shielding plates 3 on two adjacent terminal modules, thereby providing a limit for the shielding plates 3. A notch 54 is provided between the reinforcing block 51 and the adjacent reinforcing rib 53 for the front end of the shielding plate 3 to be inserted. This notch 54 can limit and reinforce the shielding plate 3, preventing the shielding plate 3 from moving or deforming.

[0076] Specific embodiment 2 of the connector provided by this utility model:

[0077] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the support plate is provided with only an insertion part and not a holding part. Since the insertion part has formed an interference fit with the slot sidewall on the insulator, the support plate can also obtain a certain holding force to keep it in the required assembly posture.

[0078] Specific embodiment 3 of the connector provided by this utility model:

[0079] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the grounding spring is only set on one of the support plates.

[0080] Specific embodiment 4 of the connector provided by this utility model:

[0081] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that in this embodiment, the grounding spring is independently processed and then fixed to the support plate by welding.

[0082] Specific embodiment 5 of the connector provided by this utility model:

[0083] This embodiment is based on Embodiment 1, and the difference from Embodiment 1 is as follows (see Appendix). Figure 15 In this embodiment, the corresponding positioning protrusions 46 on the two support plates 41 are staggered in the front-back direction and have a certain gap in the front-back direction. The positioning hole 31 is matched with each positioning protrusion 46 in a one-to-one correspondence. In this embodiment, the width of the positioning hole 31 is still twice the thickness of the positioning protrusion 46, and each positioning protrusion 46 still only has one side in contact with the positioning hole 31.

[0084] Specific embodiment 6 of the connector provided by this utility model:

[0085] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the corresponding positioning protrusions on the two support plates are staggered in the front-back direction and have a certain gap in the front-back direction. The positioning holes are matched one-to-one with each positioning protrusion, and the size of the positioning holes matches the size of the corresponding positioning protrusions.

[0086] Specific embodiment 7 of the connector provided by this utility model:

[0087] This embodiment is based on Embodiment 1, and the difference from Embodiment 1 is as follows (see Appendix). Figure 16 In this embodiment, one positioning protrusion 46 on one support plate 41 and two positioning protrusions 46 on another support plate 41 are correspondingly arranged, and the three positioning protrusions 46 are arranged in a triangular shape. The corresponding positioning holes 31 on the shielding sheet 3 allow the three positioning protrusions 46 to be inserted at the same time.

[0088] In other embodiments of this example, the number of positioning protrusions 46 inserted into the same positioning hole 31 can also be four, and the four positioning protrusions 46 can be distributed in pairs on the two support plates 41, or in triplets on the two support plates 41.

[0089] Specific embodiment 8 of the connector provided by this utility model:

[0090] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the positioning protrusions on the two support plates are not separated. In order to avoid the formation of gaps between the positioning protrusions, the positioning protrusions can be finely polished multiple times.

[0091] Specific embodiment 9 of the connector provided by this utility model:

[0092] This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the two support plates in this embodiment are set separately from each other. The two support plates can be installed between the two shielding plates in sequence, or they can be welded together beforehand and then installed between the two shielding plates.
