A person having ordinary knowledge in the technical field to which the present invention belongs will be able to best understand the technical features and other purposes and advantages of the present invention after reading the specification and drawings of the present invention.

The board-to-board connector assembly of the present invention will be described below with reference to the accompanying drawings. In each drawing, the same components or components with the same function are marked with the same component symbols. The drawings are not drawn to scale.

Referring to FIG. 1 and FIG. 2 , the components of the board-to-board connector assembly according to the present embodiment are briefly described, wherein FIG. 1 is a three-dimensional view of the board-to-board connector assembly according to the present embodiment in an engaged state, and FIG. 2 is a three-dimensional view of the board-to-board connector assembly according to the present embodiment in an unengaged state. The board-to-board connector assembly is generally indicated by the component symbol 1.

The board-to-board connector assembly 1 includes a floating connector 10 and a mating connector 20 that is mated with the floating connector 10. The floating connector 10 and the mating connector 20 are engaged with each other in a first direction D1. The floating connector 10 is fixed to the first circuit board P1 using surface mounting technology, and the mating connector 20 is fixed to the second circuit board P2 using surface mounting technology. An electrical connection is established between the first circuit board P1 and the second circuit board P2 through the board-to-board connector assembly 1. Because the floating connector 10 has a movable housing that can float, the floating connector 10 can absorb positioning errors of the connector or the circuit board.

Referring to FIG. 3 and FIG. 4 , a floating connector 10 according to an embodiment of the present invention is briefly described. As shown in FIG. 3 and FIG. 4 , the floating connector 10 includes a first housing 11 as a fixed housing, a second housing 12 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 material or a polymer material by injection molding. The signal contacts 13 and the power contacts 14 are made of a conductive material (e.g., copper or a copper alloy).

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.

The second housing 12 has a main body 120 and stoppers 121 formed at both ends of the main body 120. The main body 120 of the second housing 12 is formed with an interlocking slot 1200 as an interlocking portion. Two U-shaped metal fittings 15 are respectively assembled at both ends of the first housing 11 so as to interfere with the stoppers 121. The U-shaped metal fittings 15 prevent the second housing 12 from moving in the first direction D1 and prevent the second housing 12 from separating from the first housing 11. In this way, the second housing 12 is restricted to move relative to the first housing 11 only on a plane perpendicular to the first direction D1.

FIG5 is a three-dimensional diagram of the signal contact 13 and the power contact 14. As shown in FIG5, the signal contact 13 and the power contact 14 are arranged in two rows along the second direction D2 perpendicular to the first direction D1. The contacts in the two rows are mirror-symmetrical to each other. In each row of contacts, two power contacts 14 are respectively arranged on both sides of the signal contact group formed by the signal contacts 13 and separated from the signal contact group. However, the present invention is not limited to this, and in each row of contacts, the two power contacts 14 can also be arranged on the same side of the signal contact group. Although in this embodiment, in each row of contacts, only one power contact is arranged on each side of the signal contact group, if necessary, more than two power contacts may be arranged on each side of the signal contact group.

In this embodiment, the floating connector 10 has 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.

Each signal contact 13 includes: a signal side fixing portion 131, a first signal side holding portion 132, a signal side spring portion 133, a second signal side holding portion 134 and a signal side contact portion 135. The first signal side holding portion 132 extends from the signal side fixing portion 131. The signal side spring portion 133 connects the first signal side holding portion 132 and the second signal side holding portion 134. The signal side contact portion 135 extends from the second signal side holding portion 134. The signal side fixing portion 131 will be fixed to the circuit board by surface mounting technology. The first signal side holding portion 132 formed with a barb structure is press-fitted into the first housing 11 and held by the first housing 11. The second signal side retaining portion 134 formed with a barb structure is press-fitted into the second housing 12 and retained by the second housing 12.

The signal side spring portion 133 of the signal contact element 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.

Each power contact 14 includes a power side fixing portion 141, a first power side holding portion 142, a power side spring portion 143, a second power side holding portion 144 and a power side contact portion 145. The first power side holding portion 142 extends from the power side fixing portion 141. The power side spring portion 143 connects the first power side holding portion 142 and the second power side holding portion 144. The power side contact portion 145 extends from the second power side holding portion 144. The power side fixing portion 141 will be fixed to the circuit board by surface mounting technology. The first power supply side holding portion 142 formed with a barb structure is press-fitted to the first housing 11 and held by the first housing 11. The second power supply side holding portion 144 formed with a barb structure is press-fitted to the second housing 12 and held by the second housing 12.

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.

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 insertion slot 1200 of the second housing 12 so as to contact with the contacts of the mating connector.

FIG6 is a view of the power contact 14 enlarged and depicted in FIG5 when viewed from a third direction D3. As shown in FIG6, the power contact 14 is configured such that the center line A2 of the power-side spring portion 143 is misaligned toward the left side of the figure (i.e., toward the inward direction) relative to the center line A1 of the power-side fixing portion 141 and the center line A3 of the power-side contact portion 145. In this way, the power contact 14 can be prevented from interfering with the first housing 11 during the movement of the second housing 12 relative to the first housing 11.

FIG7 is a view of the signal contact 13 and the power contact 14 according to the embodiment of the present invention as viewed from the second direction D2. In FIG7, the signal side fixing portion, the first signal side retaining portion, the second signal side retaining portion and the signal side contact portion of the signal contact 13 are roughly overlapped with the power contact 14, and the bending structure of the signal side spring portion of the signal contact 13 is different from the bending structure of the power side spring portion of the power contact 14. This is very different from the prior art. In the known hybrid floating connector, in order to facilitate manufacturing, the spring portion of the power contact and the spring portion of the signal contact usually have the same or similar bending structure.

Since 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. In order to promote the floating of the second housing, it is very 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.

As shown in Fig. 5, a plurality of long slots 1430A and 1430B extending along the longitudinal direction are formed on the power side spring portion 143 of the power contact 14, wherein the long slot 1430A is separated from the long slot 1430B. The power side spring portion 143 is weakened by the formation of the long slots 1430A and 1430B.

It is also possible to reduce the rigidity of the power side spring portion 143 by extending the extension length of the power side spring portion 143. As shown in FIG7, the power side spring portion 143 of the power contact 14 has a vertical extension portion (i.e., the second extension portion 1433) extending in the first direction D1, and the signal side spring portion 133 of the signal contact 13 has a vertical extension portion (i.e., the second extension portion 1333) extending in the first direction D1. The power side spring portion 143 of the power contact 14 is configured such that the vertical extension portion (i.e., the second extension portion 1433) of the power side spring portion 143 is misaligned inwardly relative to the vertical extension portion (i.e., the second extension portion 1333) of the signal side spring portion 133 in the third direction D3. In this way, the extension length of the power-side spring portion 143 is extended.

FIG8 is a perspective view of a first variant of the power contact of the floating connector. The power contact according to the first variant is generally indicated by the component symbol 16. The description of the parts of the power contact 16 that are the same as the power contact 14 is omitted. The power contact 16 has 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 the power contact 16 is formed with a plurality of elongated slots 1630A and 1630B extending along its longitudinal direction, wherein the elongated slot 1630A is separated from the elongated slot 1630B. The power side spring portion 163 is weakened by forming the elongated slots 1630A and 1630B.

The power side spring portion 163 has a first extension portion 1631, a bent portion 1632 and a second extension portion 1633. FIG. 9 is a view of the signal contact 13 and the power contact 16 according to the embodiment of the present invention as viewed from the second direction D2. As shown in FIG. 9, the second extension portion 1633 is a vertical extension portion 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 misaligned 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).

FIG. 10 is a perspective view of a second variant of the power contact of the floating connector. The power contact according to the second variant is generally indicated by the component symbol 18. The description of the parts of the power contact 18 that are the same as the power contact 14 or 16 is omitted. The power contact 18 has 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 the power contact 18 is formed with a plurality of elongated slots 1830A and 1830B extending along its longitudinal direction, wherein the elongated slot 1830A is separated from the elongated slot 1830B. The power side spring portion 183 is weakened by forming the elongated slots 1830A and 1830B.

The power side spring portion 183 has a first extension portion 1831, a first bent portion 1832, a second extension portion 1833, and a second bent portion 1834. FIG. 11 is a view of the signal contact 13 and the power contact 18 according to the embodiment of the present invention as viewed from the second direction D2. As shown in FIG. 11, the second extension portion 1833 is a vertical extension portion extending in the first direction D1. In FIG. 11, the second extension portion 1833 is not aligned with the second power side holding portion 184 and the power side contact portion 185, and the second extension portion 1833 is roughly aligned with the second extension portion 1333 of the signal side spring portion 133.

The mating connector is generally indicated by the component symbol 20 .

The mating connector 20 includes a fixed housing 21, a plurality of signal contacts 22 and a plurality of power contacts 23. The fixed housing 21 is made of an insulating resin material or a polymer material by injection molding. The signal contacts 22 and the power contacts 23 are made of a conductive material (such as copper or copper alloy). The fixed housing 21 has a tongue 211 as a fitting portion.

FIG. 14 is a three-dimensional diagram of the signal contact 22 and the power contact 23. As shown in FIG. 14, the signal contact 22 and the power contact 23 are arranged in two rows along the second direction D2 perpendicular to the first direction D1. The contacts in the two rows are mirror-symmetrical to each other. In each row of contacts, two power contacts 23 are respectively arranged on both sides of the signal contact group formed by the signal contact 22 and separated from the signal contact group. However, the present invention is not limited to this. The contact layout of the mating connector depends on the contact layout of the floating connector.

Each signal contact 22 includes a signal side fixing portion 221, a first signal side holding portion 222, a signal side bending extension portion 223, a second signal side holding portion 224 and a signal side contact portion 225. The first signal side holding portion 222 extends from the signal side fixing portion 221. The signal side bending extension portion 223 connects the first signal side holding portion 222 and the second signal side holding portion 224. The signal side contact portion 225 extends from the second signal side holding portion 224. The signal side fixing portion 221 will be fixed to the circuit board by surface mounting technology. The first signal side retaining portion 222 and the second signal side retaining portion 224 formed with a barb structure are press-fitted into the fixed housing 21 and retained by the fixed housing 21. Specifically, the first signal side retaining portion 222 is fixed near the lower edge of the fixed housing 21, and the second signal side retaining portion 224 is fixed to the tongue piece 211. The signal side contact portion 225 is positioned on the tongue piece 211.
