Technical Field

[0001] This utility model belongs to the field of connector technology, and specifically relates to a Type-C connector. Background Technology

[0002] Type-C connectors are widely used in mobile phones, laptops, and various 3C terminal devices. Type-C connectors can realize data transmission and audio signal transmission. In the existing technology, the upper and lower rows of terminals are usually injection molded separately and then assembled. After the upper and lower rows of terminals are injection molded independently, structural deformation is prone to occur, resulting in poor flatness of the solder feet. Furthermore, the terminals are also prone to displacement due to heat during subsequent soldering processes, causing soldering defects, reducing product yield, and resulting in poor product reliability.

[0003] Therefore, it is necessary to provide a new technical solution to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is the low product yield and poor reliability of connectors.

[0005] To solve the above-mentioned technical problems, this utility model provides a Type-C connector, which includes an upper terminal and a lower terminal. The upper terminal includes an upper support strip with a positioning hole and an upper pin connected to the upper support strip. The lower terminal includes a riveting member corresponding to the positioning hole, a lower support strip with a through groove, and a lower pin connected to the lower support strip. One end of the riveting member is fixed to the inner wall of the through groove, and the other end of the riveting member is located outside the through groove and extends towards the lower support strip, so as to form a limiting groove that matches the upper support strip by the riveting member and the lower support strip. When the upper support strip and the lower support strip are stacked, the riveting member passes through the positioning hole, and the upper support strip is at least partially embedded in the limiting groove, so as to rivet the upper support strip and the lower support strip together in the vertical direction.

[0006] Optionally, the other end of the riveting member includes an extension section extending from one end of the riveting member in a direction away from the lower support strip, and a bent section connected to the extension section and bent in a direction close to the lower support strip, wherein the bent section, the extension section, and the lower support strip surround the limiting groove.

[0007] Optionally, the upper support strip is provided with a protrusion extending into the positioning hole, and when viewed along the vertical direction, the projections of the protrusion and the bent section at least partially overlap.

[0008] Optionally, the lower terminal also includes a limiting block connected to one end of the riveting member. The limiting block is located in the through groove and extends through the groove in a direction perpendicular to the vertical direction. The projections of the limiting block and the lower support strip at least partially overlap.

[0009] Optionally, the upper support strip and the upper pin are integrally formed, the riveting member, the lower support strip and the lower pin are integrally formed, and there are multiple riveting members, which are distributed at equal intervals.

[0010] Optionally, the upper pin includes a first support segment connected to the upper support strip and a first contact segment connected to the first support segment, the first support segment and the first contact segment being integrally formed; the lower pin includes a second support segment connected to the lower support strip and a second contact segment connected to the second support segment, the second support segment and the second contact segment being integrally formed; wherein when the upper support strip and the lower support strip are stacked, the first contact segment and the second contact segment are spaced apart to form a conductive shielding layer.

[0011] Optionally, the Type-C connector further includes a metal plate disposed between the first contact segment and the second contact segment, and the metal plate is at least partially located within the conductive shielding layer.

[0012] Optionally, the Type-C connector further includes an insulating base, which integrally covers and fixes the upper pin and the lower pin by injection molding.

[0013] Optionally, the Type-C connector further includes a metal housing with a slot, wherein the insulating base, the upper pin, and the lower pin are respectively disposed within the slot.

[0014] Optionally, the Type-C connector further includes a grounding component sleeved outside the insulating base, and an inner housing sleeved outside the insulating base and connected to the grounding component, wherein the grounding component abuts against the metal outer shell, and the inner housing is located within the slot.

[0015] Beneficial effects:

[0016] This utility model provides a Type-C connector, in which the upper pin of the upper terminal is connected to the upper support strip, and the riveting member of the lower terminal is correspondingly set with the positioning hole located on the upper support strip. One end of the riveting member is fixed to the inner wall of the through groove located on the lower support strip, the lower pin is connected to the lower support strip, and the other end of the riveting member is located outside the through groove and extends towards the lower support strip, so that the riveting member and the lower support strip form a limiting groove that matches the upper support strip. When the upper and lower support strips are stacked, the riveting member passes through the positioning hole, and the upper support strip is at least partially embedded in the interior of the limiting groove, so as to rivet the upper and lower support strips together in the vertical direction. By threading the riveting components through the positioning holes and riveting them together before injection molding, the relative positions of the upper support strip of the upper terminal and the lower support strip of the lower terminal are rigidly fixed. This ensures no relative displacement when the upper and lower terminals are stacked, and the relative positions of the upper pin of the upper terminal and the lower pin of the lower terminal are firmly constrained. This eliminates flatness deviations caused by the separate design of the upper and lower terminals, preventing flatness defects in the upper and lower pins of the connector, and thus improving product yield and reliability. This achieves the technical effect of improving product yield and reliability. Attached Figure Description

[0028] This utility model provides a Type-C connector; please refer to [link / reference]. Figures 1 to 4 As shown, Figure 1 This is a structural schematic diagram of a Type-C connector provided in an embodiment of this utility model. Figure 2 This is a schematic diagram of the structure of the upper terminal in a Type-C connector provided by an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of the lower terminal in a Type-C connector according to an embodiment of the present invention. Figure 4 This is a schematic diagram of the structure of a Type-C connector provided in this embodiment of the present invention after removing the upper terminal, the second contact section, the limiting block, the metal sheet, and the insulating base. The Type-C connector provided in this embodiment of the present invention includes an upper terminal 1 and a lower terminal 2. The upper terminal 1 includes an upper support strip 11 and an upper pin 12. The upper support strip 11 has a positioning hole 111, and the upper pin 12 is connected to the upper support strip 11. The lower terminal 2 includes a riveting member 21, a lower support strip 22, and a lower pin 23. The riveting member 21 is correspondingly disposed with the positioning hole 111. The lower support strip 22 has a through groove 221. One end of the riveting member 21 is fixed to the inner wall of the through groove 221, and the other end of the riveting member 21 is located in the through groove 221. The other end of the rivet 21 extends toward the lower support strip 22 to form a limiting groove 25 by the rivet 21 and the lower support strip 22. The limiting groove 25 matches the upper support strip 11, and the lower pin 23 is connected to the lower support strip 22. When the upper support strip 11 and the lower support strip 22 are stacked, the rivet 21 passes through the positioning hole 111, and the upper support strip 11 is at least partially embedded in the limiting groove 25 to rivet the upper support strip 11 and the lower support strip 22 together in the vertical direction.

[0029] The vertical direction can refer to the direction from the lower support strip 22 towards the upper support strip 11, i.e. Figure 1 The direction is perpendicular to the plane of the upper support belt 11. There can be multiple positioning holes 111, and the number of through slots 221 can be the same as the number of positioning holes 111. When there are two positioning holes 111, there are also two through slots 221. The two through slots 221 are set in a one-to-one correspondence with the two positioning holes 111, that is, the positioning hole 111 is directly opposite the corresponding through slot 221.

[0030] One end of the rivet 21 can be embedded into the inner wall of the through groove 221 by welding, or the rivet 21 can be integrally formed with the lower support strip 22. The other end of the rivet 21 is bent and extended out of the through groove 221, such as forming a cantilever structure. The other end of the rivet 21 can be bent toward the plane of the lower support strip 22 to enclose a U-shaped limiting groove 25.

[0031] During assembly, the operator can first align and stack the upper support strip 11 and the lower support strip 22. Mechanical pressure is then applied to force the riveting component 21 through the positioning hole 111. The edge of the upper support strip 11 near the positioning hole 111 is then embedded in the limiting groove 25, thus constraining the upper support strip 11. After riveting, the riveting component 21 can be stamped to enhance its fixing strength, ensuring no relative displacement between the upper support strip 11 of the upper terminal 1 and the lower support strip 22 of the lower terminal 2 in the horizontal direction. This prevents misalignment due to thermal expansion or vibration during subsequent injection molding.

[0032] In this embodiment, the upper pin 12 in the upper terminal 1 is connected to the upper support strip 11, and the riveting member 21 in the lower terminal 2 is correspondingly set with the positioning hole 111 located in the upper support strip 11. One end of the riveting member 21 is fixed to the inner wall of the through groove 221 located in the lower support strip 22, and the lower pin 23 is connected to the lower support strip 22. The other end of the riveting member 21 is located outside the through groove 221, and the other end of the riveting member 21 extends towards the direction close to the lower support strip 22, so that the riveting member 21 and the lower support strip 22 form a limiting groove 25 that matches the upper support strip 11. When the upper support strip 11 and the lower support strip 22 are stacked, the riveting member 21 passes through the positioning hole 111, and the upper support strip 11 is at least partially embedded in the interior of the limiting groove 25, so as to rivet the upper support strip 11 and the lower support strip 22 into one piece along the vertical direction. By riveting the rivet 21 through the positioning hole 111 before injection molding, the relative positions between the upper support strip 11 of the upper terminal 1 and the lower support strip 22 of the lower terminal 2 are rigidly fixed. This ensures no relative displacement when the upper terminal 1 and lower terminal 2 are stacked, and the relative positions of the upper pin 12 of the upper terminal 1 and the lower pin 23 of the lower terminal 2 are firmly constrained. This eliminates the flatness deviation caused by the separate arrangement of the upper terminal 1 and lower terminal 2, preventing flatness defects in the upper pin 12 and lower pin 23 of the connector, thus improving product yield and reliability. This achieves the technical effect of improving product yield and reliability.

[0033] In one embodiment, the other end of the riveting member 21 includes an extension section 211 and a bent section 212. The extension section 211 extends from one end of the riveting member 21 in a direction away from the lower support strip 22. The bent section 212 is connected to the extension section 211 and bends in a direction closer to the lower support strip 22. The bent section 212, the extension section 211, and the lower support strip 22 enclose the aforementioned limiting groove 25. When the upper support strip 11 is embedded in the limiting groove 25, the bent section 212 can provide a vertically downward pressure, and the extension section 211 can provide a horizontal restraint force, so that the upper support strip 11 cannot be displaced in the horizontal plane or in the vertical direction, which helps to eliminate the risk of displacement after the upper terminal 1 and the lower terminal 2 are overlapped.

[0034] In some embodiments, the upper support band 11 is provided with a protrusion 112 that extends toward the interior of the positioning hole 111. When viewed along the above-mentioned vertical direction, the projections of the protrusion 112 and the bent section 212 at least partially overlap. That is, the edge of the upper support band 11 located at the positioning hole 111 may have a protrusion 112 extending toward the interior of the positioning hole 111. During the riveting process, the bent section 212 squeezes the protrusion 112 to produce plastic deformation, so that the two form an interlocking structure to force the upper support band 11 and the riveting member 21 to achieve zero clearance fit in the vertical direction. This helps to eliminate assembly loosening caused by machining tolerances, improve the vibration resistance of the riveting structure, and eliminate the source of flatness deviation.

[0035] In some embodiments, the lower terminal 2 of a Type-C connector provided by this utility model further includes a limiting block 24. The limiting block 24 is connected to one end of the riveting member 21. The limiting block 24 is located inside the through groove 221, and when viewed along a direction perpendicular to the above-mentioned vertical direction, the projections of the limiting block 24 and the lower support band 22 at least partially overlap. The limiting block 24 can anchor the riveting member 21. When riveting force is applied to the riveting member 21, the contact surface between the limiting block 24 and the inner wall of the through groove 221 can disperse the stress, preventing the riveting member 21 from deflecting or slipping within the through groove 221, thereby improving the positional stability of the riveting process.

[0036] In some embodiments, the upper support strip 11 and the upper pin 12 are integrally formed, as are the riveting member 21, the lower support strip 22, and the lower pin 23. Integral forming helps eliminate assembly tolerances between components. For example, integrally stamping the upper terminal 1 can eliminate the connection gap between the upper support strip 11 and the upper pin 12. Integral forming of the lower terminal 2 can improve the absolute perpendicularity between the riveting member 21 and the lower support strip 22. There are multiple riveting members 21, which are evenly distributed. For example, there can be three riveting members 21. In this case, the three riveting members 21 pass through the aforementioned positioning holes 111, and their evenly distributed distribution forms a symmetrical force-bearing system, providing multi-point synchronous constraints to avoid local deformation.

[0037] In some embodiments, the upper pin 12 of the Type-C connector provided by this utility model includes a first support segment 121 and a first contact segment 122. The first support segment 121 is connected to the upper support strip 11, and the first contact segment 122 is connected to the first support segment 121. The first support segment 121 and the first contact segment 122 are integrally formed. The lower pin 23 includes a second support segment 231 and a second contact segment 232. The second support segment 231 is connected to the lower support strip 22, and the second contact segment 232 is connected to the second support segment 231. The second support segment 231 and the second contact segment 232 are integrally formed. When the upper support strip 11 and the lower support strip 22 are stacked, the first contact segment 122 and the second contact segment 232 are spaced apart to form a conductive shielding layer 222. That is, when the upper support strip and the lower support strip are stacked, the spaced arrangement of the first contact segment 122 and the second contact segment 232 can form a conductive shielding layer 222 to suppress signal crosstalk. The interior of the conductive shielding layer 222 has a space to accommodate the metal sheet 3 described below.

[0038] In some embodiments, the Type-C connector provided by this utility model further includes a metal piece 3, which is disposed between the first contact segment 122 and the second contact segment 232, and the metal piece 3 is at least partially located inside the conductive shielding layer 222. When the metal piece 3 is encased inside the conductive shielding layer 222, the metal piece 3, together with the first contact segment 122 and the second contact segment 232, forms a multi-layer electromagnetic isolation cavity. For example, by absorbing high-frequency interference signals, the metal piece 3 can block the electric field coupling between the upper pin 12 and the lower pin 23, thereby eliminating the risk of signal crosstalk in high-speed transmission and improving the reliability of the electrical connection.

[0039] In some embodiments, the Type-C connector provided by this utility model further includes an insulating base 4. The insulating base 4 integrally covers and fixes the upper pin 12 and the lower pin 23 by injection molding. Before injection molding, the upper terminal 1 and the lower terminal 2 can be rigidly riveted to eliminate the positional deviation of the upper pin 12 and the lower pin 23 in advance. Then, the upper pin 12 and the lower pin 23 are firmly limited by the molten plastic wrapping the upper pin 12 and the lower pin 23 in a zero displacement state.

[0040] In some embodiments, the Type-C connector provided by this utility model further includes a metal housing (not shown), on which a slot (not shown) is provided. An insulating base 4, an upper pin 12, and a lower pin 23 are respectively disposed inside the slot. The slot of the metal housing has space to accommodate the insulating base 4, the upper pin 12, and the lower pin 23. Distributing the insulating base 4, the upper pin 12, and the lower pin 23 inside the slot not only facilitates the insertion and removal of the connector but also improves the mechanical protection performance and electromagnetic shielding effect of the connector.

[0041] In some embodiments, the Type-C connector provided by this utility model further includes a grounding element (not shown) and an inner shell (not shown). The grounding element is sleeved on the outside of the insulating base 4 and abuts against the metal shell. The inner shell is sleeved on the outside of the insulating base 4 and connected to the grounding element. The inner shell is located inside the slot. The connection between the inner shell and the grounding element can enhance the grounding effect of the connector, thereby improving the overall insulation performance.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] 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.
