Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and more specifically to a connector. Background Technology

[0002] Existing connectors include an insulated outer housing and several terminal modules mounted on the outer housing. Each terminal module includes terminals and an insulator that are injection molded together. The terminals are arranged in pairs to form differential pairs. Each terminal includes a spring end and a fisheye end. The end where the fisheye end of the connector is located is the crimp end. A first shielding plate and a second shielding plate are respectively provided on both sides in the thickness direction of the insulator. The first shielding plate and the second shielding plate are arranged opposite to each other. Each differential pair is arranged between the first shielding plate and the second shielding plate. In order to enhance the shielding effect of the fisheye end, a conductive buckle is currently provided at the fisheye end. The conductive buckle is used to shield and conduct the shielding plates of each terminal module.

[0003] For example, a high-speed orthogonal connector disclosed in Chinese invention patent CN113690695B includes a bent female chip (terminal module) and two shielding plates. The shielding plates are shielding sheets, and each shielding plate has a grounding fisheye. The grounding fisheye constitutes a grounding crimping part on the shielding plate. The crimping end of the bent female chip has a conductive buckle. For the installation structure of the conductive buckle, the conductive buckle has multiple signal terminal avoidance holes and multiple grounding pin holes. The surface of the conductive buckle facing the chip also has multiple conductive buckle tabs. The conductive buckle tabs are the horizontal ribs between the grounding pin holes and the signal terminal avoidance holes. When the bent female conductive buckle is fastened to the crimping surface formed by the fisheye ends of the multiple bent female chips, the differential pairs at the crimping part of the bent female signal terminals enter the corresponding signal terminal avoidance holes, the fisheyes of the bent female shielding plate enter the corresponding grounding pin holes, and the conductive buckle tabs are inserted into the corresponding slots. The slots include slots provided on the edge of the shielding plate. The conductive buckle tabs are forcibly inserted into the slots so that the sidewalls of the tabs contact the bent female shielding plate. Regarding the aforementioned installation structure of conductive buckles, since conductive buckles are usually made of conductive plastic and the components of the connector are very compact, after forming signal clearance holes for signal crimping parts of signal terminals and ground clearance holes for ground crimping parts on the shielding sheet on the conductive buckle, the part of the conductive buckle between the signal clearance holes and the ground clearance holes is relatively thin. That is, the conductive buckle tabs are relatively thin and weak, and the shielding sheet is also relatively thin. When the tabs are forcibly inserted into the slots of the rigid shielding sheet, they are more likely to be damaged. Moreover, conductive debris is easily squeezed out when the conductive buckle tabs are inserted, which poses a risk of short circuit. Summary of the Invention

[0004] The purpose of this invention is to provide a connector that solves the problem that the conductive backing plate of current connectors is easily damaged during installation.

[0005] The technical solution of the connector of the present invention is as follows:

[0006] A connector includes a terminal module and a conductive snap plate. The terminal module includes an insulator and a signal crimp portion and a ground crimp portion located at the crimp end of the connector. The conductive snap plate has a signal clearance hole for avoiding the signal crimp portion and a ground clearance hole for avoiding the ground crimp portion. A conductive shield is provided on one side of the insulator in the thickness direction. The conductive shield includes a main body and an insert portion protruding from the edge of the main body near the crimp end of the connector. The conductive snap plate has an assembly groove for forcibly mounting the insert portion. The side of the insert portion in the thickness direction contacts the groove wall of the assembly groove.

[0007] Beneficial effects: By setting an insert part on the conductive shielding sheet and setting an assembly groove on the conductive buckle plate, the insert part is forcibly installed in the assembly groove, and the side of the insert part in the thickness direction contacts the groove wall of the assembly groove. Since the insert part on the shielding sheet has good strength, it is not easy to be damaged during forced installation, and the conductive buckle plate is not easily damaged because the side of the insert part in the thickness direction contacts the groove wall of the assembly groove.

[0008] Furthermore, the insert portion includes a fixing section, the thickness direction of which is perpendicular to the thickness direction of the main body, and the fixing section has a fixing part that is forcibly fitted with the groove wall of the assembly groove.

[0009] Beneficial effects: The assembly slot corresponding to the fixing section can be set between two adjacent signal clearance holes of the conductive buckle plate, which helps to reduce the size and makes it easier to shield the signal terminals of the terminal module using the fixing section.

[0010] Furthermore, the insert portion is a bent portion located at the edge of the main body. The bent portion includes a first segment and a second segment arranged vertically. The first segment is connected to the main body, and the second segment constitutes a fixed segment.

[0011] Beneficial effects: The use of the bending section to form a fixed section facilitates the forming of the shielding sheet and results in a stable structure.

[0012] Furthermore, the terminal module includes a signal terminal. An insulating protrusion is provided on the edge of the insulator near the connector crimp end. The signal crimp portion of the signal terminal protrudes from the insulating protrusion. The conductive buckle plate is provided with a mounting groove for the insulating protrusion to be inserted. The signal clearance hole and the ground clearance hole are both provided at the bottom of the mounting groove. The assembly groove includes a first groove and a second groove respectively provided on the groove sidewalls on both sides of the insulator thickness direction of the mounting groove. The first section extends into the first groove, and the fixed part of the second section is installed in the second groove.

[0013] Beneficial effects: The use of mounting grooves and insulating protrusions facilitates the fixing of conductive buckles and insulators, and also makes the machining of assembly grooves easier.

[0014] Furthermore, the grounding crimping part is set on the fixed section, and the grounding avoidance hole is connected to the assembly groove.

[0015] Beneficial effects: Using a fixed section to set the grounding crimping part simplifies the structure of the shielding sheet and facilitates its forming.

[0016] Furthermore, the fixing part is located on the side of the grounding crimping part away from the main body.

[0017] The beneficial effect is that the assembly groove can reliably fix the fixed section, making it easier to bear force when the grounding crimping part is crimped.

[0018] Furthermore, the assembly slot is equipped with a strong mounting protrusion.

[0019] Beneficial effects: By utilizing the strong mounting protrusion to form a strong mounting fit with the insert part, the contact area between the insert part and the groove wall of the assembly groove is reduced, ensuring reliable contact and reducing friction.

[0020] Furthermore, the mounting protrusion has a guide surface for guiding the insert portion into the assembly slot.

[0021] Beneficial effects: The guide surface guides the insert part into the assembly slot, which facilitates installation and reduces wear.

[0022] Furthermore, the conductive shielding sheet is the first shielding sheet, and a second shielding sheet is provided on the other side of the insulation thickness direction. The second shielding sheet is provided with a spring claw, and the conductive buckle plate is also provided with a contact groove for the spring claw to extend into.

[0023] Beneficial effect: The second shielding plate's spring claws extend into the contact groove to connect with the conductive buckle plate, improving the shielding effect.

[0024] Furthermore, the root of the signal crimping part is provided with a bending structure, and the conductive buckle plate is provided with a shielding space to accommodate the bending structure.

[0025] Beneficial effect: The bending structure of the signal terminal is located within the shielding space of the conductive buckle plate, which is beneficial for shielding the electromagnetic interference generated by signal transmission in the bending area. Attached Figure Description

Detailed Implementation

[0042] Embodiment 1 of the connector of the present invention:

[0043] In this embodiment, an insert portion is provided on the conductive shielding sheet, and an assembly groove is provided on the conductive buckle plate, so that the insert portion is forcibly installed in the assembly groove, and the side of the insert portion in the thickness direction contacts the groove wall of the assembly groove. Since the insert portion on the shielding sheet has good strength, it is not easy to be damaged during forced installation, and the conductive buckle plate is not easily damaged because the side of the insert portion in the thickness direction contacts the groove wall of the assembly groove.

[0044] like Figure 1-15 As shown, the connector includes several terminal modules 100 and an outer fixing shell 200 for fixing each terminal module 100. The terminal modules 100 are arranged side-by-side in a left-right direction. Each terminal module 100 includes an insulator 3, a signal terminal 2, a first shielding plate 4, and a second shielding plate 5. The thickness direction of the insulator 3 is left-right. The first shielding plate 4 and the second shielding plate 5 are respectively disposed on the left and right sides of the insulator 3. The signal terminal 2 is integrally formed and fixed to the insulator 3. The signal terminals 2 are arranged in pairs to form differential pairs. The signal terminal 2 has a fisheye end 21 and a spring end 22. The spring end 22 faces downwards, and the fisheye end 21 faces forward. The fisheye end 21 of the signal terminal 2 is a signal crimping part, and the spring end 22 is used for insertion with the contact of the adapter connector. The end of the connector with the fisheye end 21 constitutes the connector crimping end. The connector crimping end is provided with a conductive buckle 1, which is used to conduct the shielding plates of each terminal module 100 to shield the root area of ​​the fisheye end 21 of the signal terminal 2.

[0045] The insulating body of the insulator 3 of the terminal module 100 has an insulating protrusion 31 at the edge near the connector crimp end. The insulating protrusion 31 corresponds to the differential pair. The fisheye end 21 of the signal terminal 2 protrudes from the insulating protrusion 31. The root of the fisheye end 21 of the signal terminal 2 has a bending structure. The area where the bending structure is located constitutes the bending area 300. The bending structure of the differential pair is located in the corresponding insulating protrusion 31.

[0046] The first shielding plate 4 constitutes a conductive shielding plate. The first shielding plate 4 includes a main plate body and a claw 41 protruding from the edge of the main plate body near the connector crimping end. The claw 41 constitutes an insertion portion. The claw 41 is a bent portion provided on the edge of the main plate body of the first shielding plate 4. The bent portion includes a first segment and a second segment arranged vertically. The first segment is flush with the main plate body and integrally connected. The second segment constitutes a fixing segment. The thickness direction of the fixing segment is perpendicular to the thickness direction of the main plate body of the first shielding plate 4. The second segment is bent relative to the first segment toward the insulator 3. The fixing segment of the claw 41 is provided with a grounding eye 43. The grounding eye 43 constitutes a grounding crimping portion. The gap between two adjacent insulating protrusions 31 of the terminal module 100 allows the fixing segment of the corresponding claw 41 to be inserted. The claw 41 has a fixing portion 42 extending into the insulating protrusion 31 and facing away from the main plate body of the first shielding plate 4. The differential pair of the terminal module 100 is provided with claws 41 on both the upper and lower sides. The orientation of the fisheye hole on the claw 41 is perpendicular to the orientation of the fisheye hole on the signal terminal 2. The grounding fisheye 43 and the fisheye end 21 of the signal terminal 2 are positioned to be crimped.

[0047] The second shielding plate 5 includes a main plate body and a spring claw 51 disposed on the edge of the main plate body near the connector crimping end. The spring claw 51 extends forward and its root bends toward the insulator 3. The spring claw 51 is located on the side of the insulating protrusion 31 opposite to the main plate body of the first shielding plate 4. The spring claw 51 corresponds one-to-one with the differential pair.

[0048] The conductive buckle plate 1 is provided with mounting grooves 10 corresponding to the terminal modules 100 one by one. Each mounting groove 10 is spaced apart in the left and right direction. The opening of the mounting groove 10 faces backward. The mounting groove 10 extends vertically and is arranged vertically and through, so that the insulating protrusions 31 of the terminal modules 100 can be inserted. The bottom of the mounting groove 10 is provided with a signal avoidance hole 11 and a grounding avoidance hole 14. The signal avoidance hole 11 is used to avoid the fisheye end 21 of the signal terminal 2, and the grounding avoidance hole 14 is used to avoid the grounding fisheye 43 on the first shielding plate 4. There are grounding avoidance holes 14 on both the upper and lower sides of the signal avoidance hole 11. The conductive buckle plate 1 is also provided with an assembly groove for assembling the claw 41 of the first shielding plate 4. The assembly groove includes a limiting groove 15 and a fixing groove 12 respectively provided on the left and right side walls of the mounting groove 10. The limiting groove 15 and the fixing groove 12 respectively form the first groove and the second groove. The first section of the claw 41 extends into the first groove, and the second section spans across the two side walls of the mounting groove 10. The fixing part 42 of the second section is installed in the second groove. The limiting groove 15 and the fixing groove 12 both have rearward openings for the corresponding parts of the first shielding plate 4 to be installed.

[0049] The upper and lower sides of the fixing groove 12 are respectively provided with mounting protrusions 120. The side of the fixing part 42 in the thickness direction is rigidly fitted with the mounting protrusions 120. The mounting protrusions 120 are part of the groove wall of the assembly groove. The two mounting protrusions 120 of the fixing groove 12 are located on both sides of the fixing part 42. The mounting protrusions 120 and the two side of the fixing part 42 of the claw 41 in the thickness direction form a tight contact, reducing the contact area between the insert part and the groove wall of the assembly groove, ensuring reliable contact and reducing friction. The first shielding plate 4 is made of metal, and the conductive buckle 1 is made of conductive plastic. The rigid plate-type claw 41 is inserted between the two flexible mounting protrusions 120, which is conducive to the conductive buckle 1 and the shielding plate being rigidly installed in place, and also helps to avoid the generation of conductive debris. The mounting protrusions 120 have guide slopes 121 for guiding the fixing part 42 into the fixing groove 12. The guide slopes 121 form a guide surface to reduce the wear of the fixing part 42 on the conductive buckle 1.

[0050] The mounting groove 10 of the conductive buckle plate 1, corresponding to the second shielding sheet 5, is also provided with a contact groove 13 for the spring claw 51 to extend into. The contact groove 13 is shaped to match the spring claw 51. The contact groove 13 has a rearward opening and a groove bottom surface facing the spring claw 51. When the spring claw 51 of the second shielding sheet 5 is inserted into the contact groove 13, the insulating protrusion 31 of the corresponding insulator 3 clamps the spring claw 51 with the groove bottom surface of the contact groove 13, so that the spring claw 51 is in close contact with the conductive buckle plate 1, thereby improving the shielding effect. Since the differential pairs of the terminal modules 100 in this embodiment are staggered, in order to ensure a compact structure, a notch is provided on the groove bottom surface of the contact groove 13. This notch is connected to the limiting groove 15 at another mounting groove 10, which facilitates the improvement of the shielding effect.

[0051] The two adjacent claws 41 of the first shielding plate 4 and the opposite side walls of the mounting groove 10 form a shielding cavity. The thickness of the conductive buckle plate 1 is greater than the length of the bending area 300. The bending area 300 of the signal terminal 2 is located in the shielding cavity of the conductive buckle plate 1, which is beneficial to shielding the electromagnetic interference generated by the signal transmission of the bending area 300.
