[0120] The board-to-board connector assembly according to an embodiment of the present invention will be described below with reference to the accompanying drawings. In each of the drawings, identical components or components having identical functions are denoted by identical reference numerals. The drawings are not drawn to scale.

[0121] Reference Figure 1 and Figure 2 , briefly describes the components of the board-to-board connector assembly according to an embodiment of the present invention, wherein Figure 1 is a perspective view of a board-to-board connector assembly in a mating state according to an embodiment of the present invention, and Figure 2 FIG1 is a perspective view of a board-to-board connector assembly according to an embodiment of the present invention in an unmated state. The board-to-board connector assembly is generally designated by reference numeral 1.

[0122] The board-to-board connector assembly 1 includes a floating connector 10 and a mating connector 20 that mates with the floating connector 10. The floating connector 10 and the mating connector 20 mate with each other in a first direction D1. The floating connector 10 is secured to a first circuit board P1 using surface mount technology, while the mating connector 20 is secured to a second circuit board P2 using surface mount technology. The board-to-board connector assembly 1 establishes an electrical connection between the first circuit board P1 and the second circuit board P2. Because the floating connector 10 has a movable, floating housing, it can accommodate positioning errors in the connectors or circuit boards.

[0123] Reference Figure 3 and Figure 4 , briefly describes the floating connector 10 according to an embodiment of the present invention. Figure 3 and Figure 4As shown, the floating connector 10 includes a first housing 11 serving as a fixed housing, a second housing 12 serving as a movable housing, a plurality of signal contacts 13, and a plurality of power contacts 14. The first housing 11 and the second housing 12 are made of an insulating resin or polymer material by injection molding. The signal contacts 13 and the power contacts 14 are made of a conductive material, such as copper or a copper alloy.

[0124] The first housing 11 has a receiving space 110, and the lower portion of the second housing 12 is received in the receiving space 110. A gap is left between the first housing 11 and the second housing 12, allowing the second housing 12 to move relative to the first housing 11 in a plane perpendicular to the first direction D1.

[0125] The second housing 12 includes a main body 120 and stoppers 121 formed at each end of the main body 120. The main body 120 of the second housing 12 is formed with a mating slot 1200 serving as a mating portion. Two U-shaped metal fittings 15 are mounted on each end of the first housing 11 to interfere with the stoppers 121. The U-shaped metal fittings 15 prevent movement of the second housing 12 in the first direction D1 and prevent the second housing 12 from separating from the first housing 11. In this manner, the second housing 12 is restricted to movement relative to the first housing 11 only in a plane perpendicular to the first direction D1.

[0126] Figure 5 FIG is a perspective view of the signal contact 13 and the power contact 14. Figure 5 As shown, the signal contacts 13 and the power contacts 14 are arranged in two rows along a second direction D2 perpendicular to the first direction D1. The contacts in the two rows are mirror-symmetrical. In each row of contacts, two power contacts 14 are respectively arranged on either side of a signal contact group consisting of signal contacts 13 and are separated from the signal contact group. However, the present invention is not limited to this. In each row of contacts, the two power contacts 14 may also be arranged on the same side of the signal contact group. Although in this embodiment, only one power contact is arranged on each side of the signal contact group in each row of contacts, more than two power contacts may be arranged on each side of the signal contact group if desired.

[0127] In this embodiment, the floating connector 10 includes 140 signal contacts 13 and 4 power contacts 14. However, the present invention is not limited thereto, and the number of signal contacts or power contacts can be increased or decreased as needed.

[0128] Each signal contact 13 includes a signal-side fixing portion 131, a first signal-side retaining portion 132, a signal-side spring portion 133, a second signal-side retaining portion 134, and a signal-side contact portion 135. The first signal-side retaining portion 132 extends from the signal-side fixing portion 131. The signal-side spring portion 133 connects the first signal-side retaining portion 132 and the second signal-side retaining portion 134. The signal-side contact portion 135 extends from the second signal-side retaining portion 134. The signal-side fixing portion 131 is secured to a circuit board using surface mounting technology. The first signal-side retaining portion 132, which has a barbed structure, is press-fitted into and retained by the first housing 11. The second signal-side retaining portion 134, which has a barbed structure, is press-fitted into and retained by the second housing 12.

[0129] The signal-side spring portion 133 of the signal contact 13 sequentially includes a first extension portion 1331, a first bent portion 1332, a second extension portion 1333, a second bent portion 1334, and a third extension portion 1335. The first extension portion 1331 and the third extension portion 1335 extend obliquely relative to the first direction D1. The second extension portion 1333 extends in the first direction D1.

[0130] Each power contact 14 includes a power-side fixing portion 141, a first power-side retaining portion 142, a power-side spring portion 143, a second power-side retaining portion 144, and a power-side contact portion 145. The first power-side retaining portion 142 extends from the power-side fixing portion 141. The power-side spring portion 143 connects the first power-side retaining portion 142 and the second power-side retaining portion 144. The power-side contact portion 145 extends from the second power-side retaining portion 144. The power-side fixing portion 141 is secured to the circuit board using surface mounting technology. The first power-side retaining portion 142, which has a barbed structure, is press-fitted into the first housing 11 and retained by the first housing 11. The second power-side retaining portion 144, which has a barbed structure, is press-fitted into the second housing 12 and retained by the second housing 12.

[0131] The power-side spring portion 143 of the power contact 14 sequentially includes a first extension portion 1431, a first bent portion 1432, a second extension portion 1433, a second bent portion 1434, and a third extension portion 1435. The first extension portion 1431 and the third extension portion 1435 extend obliquely relative to the first direction D1. The second extension portion 1433 extends in the first direction D1.

[0132] The signal-side contact portion 135 of the signal contact 13 and the power-side contact portion 145 of the power contact 14 are located in the fitting slot 1200 of the second housing 12 so as to contact with the contacts of the mating connector.

[0133] Figure 6 yes Figure 5The power contact 14 is enlarged and depicted in FIG. 1 , and is viewed from a third direction D3. Figure 6 As shown, the power contact 14 is configured such that the centerline A2 of the power-side spring portion 143 is offset toward the left (i.e., inward) in the drawing relative to the centerline A1 of the power-side fixing portion 141 and the centerline A3 of the power-side contact portion 145. This prevents interference between the power contact 14 and the first housing 11 during movement of the second housing 12 relative to the first housing 11.

[0134] Figure 7 FIG. 1 is a view of the signal contact 13 and the power contact 14 according to an embodiment of the present invention viewed from the second direction D2. Figure 7 In the embodiment, the signal-side fixing portion, first signal-side retaining portion, second signal-side retaining portion, and signal-side contact portion of the signal contact 13 substantially overlap with the power contact 14. However, the bending structure of the signal-side spring portion of the signal contact 13 differs from the bending structure of the power-side spring portion of the power contact 14. This is a significant departure from conventional technology. In conventional hybrid floating connectors, for ease of manufacturing, the spring portions of the power contact and the signal contact typically have the same or similar bending structures.

[0135] Because the power contact 14 has a greater width than the signal contact 13, the power-side spring portion 143 of the power contact 14 has a greater stiffness than the signal-side spring portion 133 of the signal contact 13. To facilitate floating of the second housing, it is advantageous to reduce the stiffness of the power-side spring portion 143 of the power contact 14 so that the power-side spring portion 143 of the power contact 14 is more easily deformed.

[0136] As can be seen in Figure 5 The power-side spring portion 143 of the power contact 14 is formed with a plurality of elongated slots 1430A and 1430B extending along its longitudinal direction, wherein the elongated slots 1430A and 1430B are separated from each other. The elongated slots 1430A and 1430B weaken the power-side spring portion 143.

[0137] It is also possible to reduce the rigidity of the power supply side spring portion 143 by extending the extension length of the power supply side spring portion 143. Figure 7As shown, the power-side spring portion 143 of the power contact 14 has a vertically extending portion (i.e., the second extending portion 1433) extending in the first direction D1, while the signal-side spring portion 133 of the signal contact 13 has a vertically extending portion (i.e., the second extending portion 1333) extending in the first direction D1. The power-side spring portion 143 of the power contact 14 is configured such that the vertically extending portion (i.e., the second extending portion 1433) of the power-side spring portion 143 is offset inward in the third direction D3 relative to the vertically extending portion (i.e., the second extending portion 1333) of the signal-side spring portion 133. This increases the extension length of the power-side spring portion 143.

[0138] Figure 8 This is a perspective view of a first variation of a floating connector power contact. The power contact according to the first variation is generally designated by reference numeral 16. Descriptions of the portions of power contact 16 that are identical to power contact 14 are omitted. Power contact 16 includes a power-side fixing portion 161, a first power-side retaining portion 162, a power-side spring portion 163, a second power-side retaining portion 164, and a power-side contact portion 165. The power-side spring portion 163 of power contact 16 is formed with a plurality of elongated slots 1630A and 1630B extending longitudinally thereof, with elongated slots 1630A and 1630B separated from each other. The formation of elongated slots 1630A and 1630B weakens the power-side spring portion 163.

[0139] The power supply-side spring portion 163 includes a first extending portion 1631 , a bent portion 1632 , and a second extending portion 1633 . Figure 9 FIG. 1 is a view of the signal contact 13 and the power contact 16 according to an embodiment of the present invention viewed from the second direction D2. Figure 9 As shown, the second extension portion 1633 is a vertical extension extending in the first direction D1 and is aligned with the second power-side retaining portion 164 and the power-side contact portion 165. The power-side spring portion 163 of the power contact 16 is configured such that the vertical extension portion of the power-side spring portion 163 (i.e., the second extension portion 1633) is offset inwardly in the third direction D3 relative to the vertical extension portion of the signal-side spring portion 133 (i.e., the second extension portion 1333).

[0140] Figure 10This is a perspective view of a second variation of the power contact of a floating connector. The power contact according to the second variation is generally designated by reference numeral 18. Descriptions of portions of power contact 18 that are identical to power contacts 14 or 16 are omitted. Power contact 18 includes a power-side fixing portion 181, a first power-side retaining portion 182, a power-side spring portion 183, a second power-side retaining portion 184, and a power-side contact portion 185. The power-side spring portion 183 of power contact 18 is formed with a plurality of elongated slots 1830A and 1830B extending longitudinally thereof, with elongated slots 1830A and 1830B separated from each other. The formation of elongated slots 1830A and 1830B weakens the power-side spring portion 183.

[0141] The power supply-side spring portion 183 includes a first extending portion 1831 , a first bent portion 1832 , a second extending portion 1833 , and a second bent portion 1834 . Figure 11 FIG. 1 is a view of the signal contact 13 and the power contact 18 according to an embodiment of the present invention viewed from the second direction D2. Figure 11 As shown, the second extension portion 1833 is a vertical extension portion extending in the first direction D1. Figure 11 , the second extending portion 1833 is not aligned with the second power-side holding portion 184 and the power-side contact portion 185 , and the second extending portion 1833 is substantially aligned with the second extending portion 1333 of the signal-side spring portion 133 .

[0142] The following will refer to Figure 12 and 13 The floating connector 10 is briefly described as a counterpart connector, wherein Figure 12 A perspective view of the counterpart connector of the floating connector 10, Figure 13 2 is an exploded perspective view of a mating connector of the floating connector 10. The mating connector is generally denoted by reference numeral 20.

[0143] The mating connector 20 includes a stationary housing 21, a plurality of signal contacts 22, and a plurality of power contacts 23. The stationary housing 21 is made of an insulating resin or polymer material by injection molding. The signal contacts 22 and power contacts 23 are made of a conductive material (e.g., copper or a copper alloy). The stationary housing 21 has a tongue 211 that serves as a mating portion.

[0144] Figure 14 FIG is a perspective view of the signal contact 22 and the power contact 23. Figure 14As shown, the signal contacts 22 and power contacts 23 are arranged in two rows along a second direction D2 perpendicular to the first direction D1. The contacts in the two rows are mirror images of each other. In each row, two power contacts 23 are positioned on either side of a group of signal contacts 22 and are separated from the group of signal contacts. However, the present invention is not limited to this. The contact layout of the mating connector is determined by the contact layout of the floating connector.

[0145] Each signal contact 22 includes a signal-side fixing portion 221, a first signal-side retaining portion 222, a signal-side bent extension 223, a second signal-side retaining portion 224, and a signal-side contact portion 225. The first signal-side retaining portion 222 extends from the signal-side fixing portion 221. The signal-side bent extension 223 connects the first signal-side retaining portion 222 and the second signal-side retaining portion 224. The signal-side contact portion 225 extends from the second signal-side retaining portion 224. The signal-side fixing portion 221 is secured to a circuit board using surface mounting technology. The first signal-side retaining portion 222 and the second signal-side retaining portion 224, each formed with a barbed structure, are press-fitted into and retained by the fixed housing 21. Specifically, the first signal-side retaining portion 222 is secured near the bottom edge of the fixed housing 21, while the second signal-side retaining portion 224 is secured to the tongue 211. The signal-side contact portion 225 is positioned on the tongue 211.

[0146] Each power contact 23 includes a power-side fixing portion 231, a first power-side retaining portion 232, a power-side bent extension 233, a second power-side retaining portion 234, and a power-side contact portion 235. The first power-side retaining portion 232 extends from the power-side fixing portion 231. The power-side bent extension 233 connects the first power-side retaining portion 232 and the second power-side retaining portion 234. The power-side contact portion 235 extends from the second power-side retaining portion 234. The power-side fixing portion 231 is secured to a circuit board using surface mounting technology. The first power-side retaining portion 232 and the second power-side retaining portion 234, each formed with a barbed structure, are press-fitted into and retained by the fixed housing 21. Specifically, the first power-side retaining portion 232 is secured near the lower edge of the fixed housing 21, while the second power-side retaining portion 234 is secured to the tongue 211. The power-side contact portion 235 is positioned on the tongue 211.

[0147] Figure 15 FIG. 2 is a view of the signal contact 22 and the power contact 23 of the mating connector 20 viewed from a third direction D3. Figure 15As shown, the centerline A5 of the power-side contact portion 235 is offset inward in the second direction D2 relative to the centerline A4 of the power-side fixing portion 231. By offsetting the power-side contact portion 235 relative to the power-side fixing portion 231, even when the solder pad layout of the circuit board is predetermined (i.e., the gap between the signal contacts and the power contacts on the soldering side is predetermined and cannot be changed), the power contacts can still be used to adjust the gap between the signal contacts and the power contacts on the contact side so that the gap on the contact side matches that of the mating floating connector.

[0148] Although the present invention has been described with reference to preferred embodiments, it should be understood that numerous variations and modifications are possible for those skilled in the art without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the disclosed embodiments but is subject to the text of the claims. Equivalent variations and modifications that do not depart from the scope of the claims are intended to be within the scope of the present invention.
