Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and in particular to a connector. Background Art

[0002] The existing connector includes an insulating external fixed shell and a plurality of terminal modules installed on the external fixed shell. The terminal module includes a terminal and an insulator that are injection molded together. The terminals are arranged in pairs to form differential pairs. The terminals include a spring end and a fisheye end. The end where the fisheye end of the connector is located is the crimping end. The first shielding sheet and the second shielding sheet are respectively provided on both sides in the thickness direction of the insulator. The first shielding sheet and the second shielding sheet are arranged opposite to each other. Each differential pair is arranged between the first shielding sheet and the second shielding sheet. In order to enhance the shielding effect of the fisheye end, a conductive buckle plate is currently arranged at the fisheye end, and the shielding sheets of each terminal module are shielded and connected by using the conductive buckle plate.

[0003] For example, a high-speed orthogonal connector disclosed in a Chinese invention patent with authorization announcement number CN113690695B includes a bent mother chip (terminal module) and shielding plates on both sides, the shielding plates are shielding sheets, grounding fisheyes are respectively provided on the shielding plates on both sides, the grounding fisheyes constitute the grounding crimping part on the shielding plate, and a conductive buckle plate is provided at the crimping end of the bent mother chip. For the installation structure of the conductive buckle plate, the conductive buckle plate is provided with a plurality of signal terminal avoidance holes and a plurality of grounding pinholes, and a plurality of conductive buckle plate convex pieces are also provided on the surface of the conductive buckle plate facing the chip, the conductive buckle plate convex pieces are transverse ribs between the grounding pinholes and the signal terminal avoidance holes, when the bent mother conductive buckle plate is buckled on the crimping surface formed by the fisheye ends of the plurality of bent mother chips, the differential pairs at the crimping part of the bent mother signal terminal respectively enter the corresponding signal terminal avoidance holes, the fisheyes of the bent mother shielding plate respectively enter the corresponding grounding pinholes, and the conductive buckle plate convex pieces are respectively inserted into the corresponding slits, the slits include narrow grooves provided at the edges of the shielding plate, and the conductive buckle plate convex pieces are forcibly inserted into the narrow grooves so that the side walls of the convex pieces contact the bent mother shielding plate. As for the installation structure of the above-mentioned conductive buckle plate, since the conductive buckle plate is usually made of conductive plastic and the structures of the various components of the connector are very compact, after the signal avoidance hole for avoiding the signal crimping part of the signal terminal and the grounding avoidance hole for avoiding the grounding crimping part on the shielding plate are formed on the conductive buckle plate, the portion of the conductive buckle plate located between the signal avoidance hole and the grounding avoidance hole is thinner, that is, the conductive buckle plate protrusion is thinner and weaker in strength, and the shielding plate is thinner. When the protrusion is forcibly inserted into the narrow slot of the rigid shielding plate, it is easier to be damaged, and conductive debris is easily squeezed out when the conductive buckle plate protrusion is inserted, and there is a risk of causing a short circuit.

[0015] Beneficial effect: The grounding crimping portion is provided by utilizing the fixed section, which simplifies the structure of the shielding sheet and facilitates forming.

[0016] Furthermore, the fixing portion is located at a side of the grounding crimping portion away from the main sheet body.

[0017] Beneficial effect: the fixing section can be reliably fixed by utilizing the assembly groove, so that the force is applied when the grounding crimping part is crimped.

[0018] Furthermore, a strong mounting protrusion is provided in the mounting groove.

DETAILED DESCRIPTION

[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 can be forcibly installed in the assembly groove and the side surface 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 surface 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 a plurality of terminal modules 100 and an outer fixed shell 200 for fixing each terminal module 100. Each terminal module 100 is arranged side by side in the left-right direction. The terminal module 100 includes an insulator 3, a signal terminal 2, a first shielding sheet 4, and a second shielding sheet 5. The thickness direction of the insulator 3 is the left-right direction. The first shielding sheet 4 and the second shielding sheet 5 are respectively arranged on the left and right sides of the insulator 3. The signal terminal 2 is integrally formed and fixed together with the insulator 3. The signal terminal 2 is arranged in pairs to form a differential pair. The signal terminal 2 has a fisheye end 21 and a spring end 22. The spring end 22 faces downward and the fisheye end 21 faces forward. The fisheye end 21 of the signal terminal 2 is a signal crimping portion. The spring end 22 is used to plug with the contact of the adapter connector. One end of the connector with the fisheye end 21 constitutes a connector crimping end. The connector crimping end is provided with a conductive buckle plate 1. The conductive buckle plate 1 is used to conduct the shielding sheets of each terminal module 100 to shield the root area of ​​the fisheye end 21 of the signal terminal 2.

[0045] An insulating body of the insulator 3 of the terminal module 100 is provided with an insulating protrusion 31 at the edge of the crimping end of the connector, and the insulating protrusion 31 corresponds to the differential pair one by one. The fisheye end 21 of the signal terminal 2 passes through the insulating protrusion 31, and a bending structure is provided at the root of the fisheye end 21 of the signal terminal 2. The area where the bending structure is located constitutes a bending area 300, and the bending structure of the differential pair is located in the corresponding insulating protrusion 31.

[0046] The first shielding sheet 4 constitutes a conductive shielding sheet. The first shielding sheet 4 includes a main sheet body and a claw 41 protruding from the edge of the main sheet body near the connector crimping end. The claw 41 constitutes an inserting portion. The claw 41 is a bending portion arranged at the edge of the main sheet body of the first shielding sheet 4. The bending portion includes a first section and a second section arranged vertically. The first section is flush with the main sheet body and connected as a whole. The second section constitutes a fixed section. The thickness direction of the fixed section is perpendicular to the thickness direction of the main sheet body of the first shielding sheet 4. The second section is bent relative to the first section toward the insulator 3. A grounding fish eye 43 is provided on the fixed section of the claw 41. The grounding fish eye 43 constitutes a grounding crimping portion. The gap between the two adjacent insulating protrusions 31 of the terminal module 100 is for the fixed section of the corresponding claw 41 to be inserted. The claw 41 has a fixed portion 42 extending to the insulating protrusion 31 and facing away from the main sheet body of the first shielding sheet 4. The upper and lower sides of the differential pair of the terminal module 100 are provided with claws 41, the direction of the fisheye hole on the claw 41 is perpendicular to the direction of the fisheye hole on the signal terminal 2, and the grounding fisheye 43 and the fisheye end 21 of the signal terminal 2 correspond to each other for crimping.

[0047] The second shielding sheet 5 includes a main sheet body and a spring claw 51 arranged at the edge of the main sheet body close to the crimping end of the connector. The spring claw 51 is cantilevered forward, and the root of the spring claw 51 is bent toward the side of the insulator 3. The spring claw 51 is located on the side of the main sheet body of the first shielding sheet 4 that is away from the insulating protrusion 31, and the spring claw 51 corresponds to the differential pair one by one.

[0048] The conductive buckle plate 1 is provided with mounting grooves 10 corresponding to the terminal modules 100 one by one. The mounting grooves 10 are arranged at intervals along the left and right directions. The notches of the mounting grooves 10 face backwards. The mounting grooves 10 extend up and down and are arranged through up and down to allow the insulating protrusions 31 of the terminal modules 100 to be installed. A signal avoidance hole 11 and a ground avoidance hole 14 are provided at the bottom of the mounting groove 10. The signal avoidance hole 11 is used to avoid the fisheye end 21 of the signal terminal 2, and the ground avoidance hole 14 is used to avoid the grounding fisheye 43 on the first shielding plate 4. The signal avoidance hole 11 has ground avoidance holes 14 on both the upper and lower sides. The conductive buckle plate 1 is also provided with an assembly groove for assembling a claw 41 of the first shielding plate 4. The assembly groove includes a limiting groove 15 and a fixing groove 12 respectively arranged on the left and right side walls of the mounting groove 10. The limiting groove 15 and the fixing groove 12 constitute a first groove and a second groove respectively. The first section of the claw 41 extends into the first groove, and the second section spans the two side walls of the mounting groove 10. The fixed 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 groove walls of the fixed groove 12 are respectively provided with a strong mounting protrusion 120. The side surface in the thickness direction of the fixed part 42 is strongly matched with the strong mounting protrusion 120. The strong mounting protrusion 120 is a part of the groove wall of the assembly groove. The two strong mounting protrusions 120 of the fixed groove 12 are respectively located on both sides of the fixed part 42. The strong mounting protrusion 120 and the two side surfaces in the thickness direction of the fixed part 42 of the claw 41 form a close contact, which reduces the contact area between the insert part and the groove wall of the assembly groove, ensures reliable contact, and reduces friction. The first shielding sheet 4 is made of metal, and the conductive buckle plate 1 is made of conductive plastic. The rigid sheet-type claw 41 is inserted between the two flexible strong mounting protrusions 120, which is conducive to the strong mounting of the conductive buckle plate 1 and the shielding sheet, and is conducive to avoiding the generation of conductive debris. The strong mounting protrusion 120 has a guiding inclined surface 121 for guiding the fixed part 42 to be installed into the fixed groove 12. The guiding inclined surface 121 constitutes a guiding surface to reduce the wear of the fixed part 42 on the conductive buckle plate 1.

[0050] The groove side wall of the mounting groove 10 of the conductive gusset 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 adapted to the shape of 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 installed in the contact groove 13, the insulating protrusion 31 of the corresponding insulator 3 and the groove bottom surface of the contact groove 13 clamp the spring claw 51, so that the spring claw 51 is in close contact with the conductive gusset plate 1, thereby improving the shielding effect. Since the differential pairs of each terminal module 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, and the notch is connected to the limit groove 15 at another mounting groove 10, thereby improving the shielding effect.

[0051] A shielding cavity is formed between the two adjacent claws 41 of the first shielding sheet 4 and the groove walls on the opposite sides of the installation groove 10. 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 in the bending area 300.
