Description

Technical Field

[0001] This utility model relates to a connector structure, and more particularly to a high-density, low-height floating connection structure that increases the transmission speed to 32GT / s and enables floating connection to avoid damage to parts or solder joints due to misalignment. Background Technology

[0002] As electronic components become increasingly complex, high-speed, and miniaturized, the spacing between module units within these components continues to shrink. This necessitates not only improved connection structures to prevent damage to components or solder joints due to misalignment, but also high-speed signal transmission capabilities within the electronic components. Existing electronic connection structures require either reducing terminal thickness or altering terminal appearance to simultaneously achieve floating connections and high-speed signal transmission. However, reducing terminal thickness results in poor structural stability, while altering terminal appearance leads to poor impedance matching, thus diminishing the application value of existing electronic connection structures. Utility Model Content

[0003] The purpose of this utility model is to provide a high-density, low-height floating connection structure. Its floating base can move back and forth and left and right along the horizontal front in the floating space of the fixed base by means of floating elastic terminals. It can realize floating connection to avoid damage to parts or solder joints when misaligned. Furthermore, the mating terminals of the mating connector make the overall transmission path direct and smooth, thereby increasing the transmission speed to 32GT / s.

[0004] This invention discloses a high-density, low-height floating connection structure, comprising a floating connector and a mating connector. The floating connector includes a fixed base, a floating elastic terminal, a floating base body, and a shielding plate. The fixed base body has a retaining wall and a floating space formed by the retaining wall. The floating elastic terminal has a first end and a second end opposite to the first end. The first end is fixed in the retaining wall of the fixed base body. The floating base body is disposed in the floating space of the fixed base body and has a connecting plate space. The second end of the floating elastic terminal is fixed to the floating base body, allowing the floating base body to move within the floating space of the fixed base body along a first direction and / or a second direction perpendicular to the first direction via the floating elastic terminal. The shielding plate is disposed in the connecting plate space of the floating base body and is located on one side of the second end of the floating elastic terminal. The length direction of the shielding plate is parallel to the second direction. The mating connector is used to receive the floating connector in a third direction perpendicular to the first and second directions. The mating housing has an abutment hole extending along the first direction. The mating terminal has a fourth end and a fifth end connecting to the fourth end. The mating terminal is used to assemble with the mating housing along the first direction, such that the fourth end of the mating terminal is snapped and fixed in the abutment hole of the mating housing, and the fifth end of the mating terminal is used to contact the second end of the floating elastic terminal to electrically connect the floating connector and the mating connector.

[0005] According to one embodiment of the present invention, a portion of the fourth end and the fifth end of the aforementioned mating terminal have a C-shaped appearance, and the end of the fifth end of the mating terminal away from the fourth end is bent toward the fourth end.

[0006] According to one embodiment of the present invention, the aforementioned mating terminal further has a welding end for connecting a fourth end, the welding end being used for welding to a printed circuit board.

[0007] According to one embodiment of the present invention, a portion of the fourth end and the fifth end of the aforementioned mating terminal are exposed outside the abutment hole of the mating housing.

[0008] According to one embodiment of the present invention, the aforementioned fixed base has a limiting iron lug fixed to the retaining wall, and one end of the limiting iron lug extends along the second direction and is connected to the shielding plate, and the limiting iron lug is used to move along the first direction.

[0009] According to one embodiment of the present invention, the floating elastic terminal has a third end connecting the first end and the second end, the first part of the third end of the floating elastic terminal is connected to the first end, and the second part of the third end of the floating elastic terminal is connected to the second end.

[0010] According to one embodiment of the present invention, the first part of the third end of the floating elastic terminal is bent and connected to the first end, which is located outside the fixed base and the floating base, while the second part of the third end of the floating elastic terminal is bent and connected to the second end, which is located in the floating space of the fixed base.

[0011] According to one embodiment of the present invention, when the floating seat is located in the middle of the floating space of the fixed seat, the floating seat does not contact the retaining wall of the fixed seat in the first direction and the second direction.

[0012] According to one embodiment of the present invention, the floating seat has a guide post on one side, and the docking shell of the docking connector has a guide hole between the docking terminal and the docking body.

[0013] According to one embodiment of the present invention, the guide post of the floating seat of the floating connector is used to be inserted into the guide hole of the mating shell of the mating connector in a third direction to mate the floating connector and the mating connector.

[0014] In summary, in this invention, the second end of the floating elastic terminal of the high-density, low-height floating connector is fixed to the floating base, while the first end is fixed to the retaining wall of the fixed base. This allows the floating base to move along the first and / or second horizontal directions in the floating space of the fixed base via the floating elastic terminal, achieving a floating connection and preventing damage to parts or solder joints due to misalignment. Furthermore, the mating terminals of the high-density, low-height floating connector are assembled with the mating shell along the first direction, which is significantly different from the top-and-bottom assembly method of traditional electrical connectors. This avoids signal loss at the terminal locking point, making the overall transmission path direct and smooth, thereby increasing the transmission speed of the high-density, low-height floating connector to 32GT / s. In other words, the high-density, low-height floating connector can meet the PCIe-Gen5 standard, increasing its application value. Attached Figure Description

[0029] Please refer to Figures 1 to 5 , Figure 1 A perspective view of a high-density, low-height floating connection structure 10 according to an embodiment of the present invention is shown. Figure 2 Draw Figure 1 A side view of the high-density, low-height floating connection structure 10. Figure 3 Draw Figure 1 A cross-sectional view of the high-density, low-height floating connection structure 10 along segment 3-3. Figure 4 A perspective view of a floating connector 100 according to an embodiment of the present invention is shown. Figure 5 An exploded view of a floating connector 100 according to an embodiment of the present invention is shown. Figures 1 to 5The high-density, low-height floating connection structure 10 includes a floating connector 100 and a mating connector 200. The floating connector 100 includes a fixed base 110, floating elastic terminals 120, a floating base 130, and a shielding plate 140. The fixed base 110 has a retaining wall 112 and a floating space 114 formed by the retaining wall 112. The floating elastic terminal 120 has a first end 122 and a second end 124 opposite to the first end 122. The first end 122 is fixed in the retaining wall 112 of the fixed base 110. Multiple floating elastic terminals 120 are arranged in two rows, and the distance between the two rows of floating elastic terminals 120 is approximately 0.78 mm.

[0030] In some embodiments, the floating seat 130 is disposed in the floating space 114 of the fixed seat 110 and has a connecting space 134. The second end 124 of the floating elastic terminal 120 is fixed to the floating seat 130, such that the floating seat 130 can move in the floating space 114 of the fixed seat 110 along a first direction D1 and / or a second direction D2 perpendicular to the first direction D1 by means of the floating elastic terminal 120, thereby realizing a floating connection to avoid damage to parts or solder joints due to misalignment. A shielding plate 140 is disposed in the connecting space 134 of the floating seat 130 and is located on one side of the second end 124 of the floating elastic terminal 120. The length direction of the shielding plate 140 is parallel to the second direction D2, and the shielding plate 140 can be used to avoid crosstalk between multiple floating elastic terminals 120.

[0031] In some embodiments, the mating connector 200 is used to receive the floating connector 100 along a third direction D3 perpendicular to the first direction D1 and the second direction D2. The mating housing 210 has an abutment hole 212 extending along the first direction D1. The mating terminal 220 has a fourth end 222 and a fifth end 224 connecting the fourth end 222. The mating terminal 220 is assembled with the mating housing 210 along the first direction D1 such that the fourth end 222 of the mating terminal 220 is snapped into the abutment hole 212 of the mating housing 210, and the fifth end 224 of the mating terminal 220 contacts the second end 124 of the floating resilient terminal 120 to electrically connect the floating connector 100 and the mating connector 200.

[0032] Specifically, in the high-density, low-height floating connection structure 10, the second end 124 of the floating elastic terminal 120 of the floating connector 100 is fixed to the floating base 130, while the first end 122 is fixed to the retaining wall 112 of the fixed base 110. This allows the floating base 130 to move along the first direction D1 and / or the second direction D2 of the horizontal plane in the floating space 114 of the fixed base 110 via the floating elastic terminal 120. This enables a floating connection to avoid damage to parts or solder joints when misalignment occurs.

[0033] Please refer to Figures 6 to 10 , Figure 6 A top view of a floating connector 100 according to an embodiment of the present invention is shown. Figure 7 Draw Figure 6 A cross-sectional view of the floating connector 100 along segment 7-7. Figure 8 Draw Figure 6 A cross-sectional view of the floating connector 100 along segment 8-8. Figure 9 A perspective view of a mating connector 200 according to an embodiment of the present invention is shown. Figure 10 Draw Figure 9 A cross-sectional view of the mating connector 200 along segment 10-10. Figures 6 to 10 In the process, a portion of the fourth end 222 and the fifth end 224 of the mating terminal 220 are C-shaped, and the end of the fifth end 224 of the mating terminal 220 away from the fourth end 222 is bent toward the fourth end 222. Therefore, signal loss caused at the terminal block end can be avoided, making the overall transmission path direct and smooth, thereby increasing the transmission speed of the high-density low-height floating connection structure 10 to 32GT / s.

[0034] In some embodiments, the mating terminal 220 further has a soldering end 226 for connecting the fourth end 222, which is used for soldering to the printed circuit board 300. It is worth noting that a portion of the fourth end 222 and the fifth end 224 of the mating terminal 220 are exposed outside the abutment hole 212 of the mating housing 210. That is, the mating terminal 220 of the mating connector 200 of the high-density low-height floating connection structure 10 is assembled with the mating housing 210 along the first direction D1, which is significantly different from the way terminals are assembled at the top and bottom of conventional electrical connectors. Therefore, signal loss caused at the terminal locking point can be avoided.

[0035] In some embodiments, the fixed base 110 has a limiting lug 116 fixed to the retaining wall 112, and one end of the limiting lug 116 extends along the second direction D2 and is connected to the shielding plate 140. The limiting lug 116 is elastic and can therefore be displaced along the first direction D1 to increase the floating effect. The floating elastic terminal 120 has a third end 126 connecting the first end 122 and the second end 124. The first portion of the third end 126 of the floating elastic terminal 120 is connected to the first end 122, and the second portion of the third end 126 of the floating elastic terminal 120 is connected to the second end 124. The third end 126 of the floating elastic terminal 120 is bent and connected to the first portion of the first end 122 and is located outside the fixed base 110 and the floating base 130, while the third end 126 of the floating elastic terminal 120 is bent and connected to the second portion of the second end 124 and is located in the floating space 114 of the fixed base 110.

[0036] In some embodiments, when the floating seat 130 is located in the middle of the floating space 114 of the fixed seat 110, the floating seat 130 does not contact the retaining wall 112 of the fixed seat 110 in the first direction D1 and the second direction D2. One side of the floating seat 130 has a guide post 136, and a guide hole 214 is provided between the mating housing 210 and the mating terminal 220 of the mating connector 200. The guide post 136 of the floating seat 130 of the floating connector 100 is used to insert into the guide hole 214 of the mating housing 210 of the mating connector 200 along the third direction D3 to mate the floating connector 100 and the mating connector 200.

[0037] In summary, the second end 124 of the floating elastic terminal 120 of the floating connector 100 in the high-density, low-height floating connection structure 10 is fixed to the floating base 130, while the first end 122 is fixed to the retaining wall 112 of the fixed base 110. This allows the floating base 130 to move along the first direction D1 and / or the second direction D2 of the horizontal plane in the floating space 114 of the fixed base 110 via the floating elastic terminal 120. This enables a floating connection to avoid damage to parts or solder joints due to misalignment. Furthermore, the mating terminals 220 of the mating connector 200 of the high-density low-height floating connection structure 10 are assembled with the mating housing 210 along the first direction D1, which is significantly different from the way terminals are assembled at the top and bottom of traditional electrical connectors. Therefore, it can avoid signal loss caused at the terminal locking point, making the overall transmission path direct and smooth, thereby increasing the transmission speed of the high-density low-height floating connection structure 10 to 32GT / s. In other words, the high-density low-height floating connection structure 10 can meet the PCIe-Gen5 standard, which can increase the application value of the high-density low-height floating connection structure 10.
