[0093] A board-to-board connector assembly according to an embodiment of the present application will be described below with reference to the accompanying drawings. In the drawings, the same elements or elements having the same function are denoted by the same reference numerals. The drawings are not drawn to scale.

[0094] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the constituent elements of a board-to-board connector assembly according to an embodiment of the present application will be described in outline, wherein Figure 1 is a perspective view of a board-to-board connector assembly according to an embodiment of the present application in a fitted state, Figure 2 is a perspective view of a board-to-board connector assembly according to an embodiment of the present application in an unfitted state, Figure 3 is a front view of a board-to-board connector assembly according to an embodiment of the present application in a fitted state, Figure 4 is a cross section taken along the line AA in Figure 3 . The board-to-board connector assembly as a whole is denoted by reference numeral 1.

[0095] The board-to-board connector assembly 1 includes a floating hybrid connector 10 and a non-floating hybrid connector 20. The non-floating hybrid connector 20 serves as a counterpart connector of the floating hybrid connector 10. Alternatively, the floating hybrid connector 10 serves as a counterpart connector of the non-floating hybrid connector 20. The floating hybrid connector 10 and the non-floating hybrid connector 20 are mateable with each other in a first direction D1. The floating hybrid connector 10 is fixed to a first circuit board P1 by surface mounting technology, and the non-floating hybrid connector 20 is fixed to a second circuit board P2 by surface mounting technology. An electrical connection between the first circuit board P1 and the second circuit board P2 is established by the board-to-board connector assembly 1. Because the floating hybrid connector 10 is provided with a movable housing that is floatable, the floating hybrid connector 10 can absorb positioning errors of the connectors or the circuit boards. As shown in Figure 4 When the floating hybrid connector 10 and the non-floating hybrid connector 20 are mated with each other, the contact pieces of the floating hybrid connector 10 and the non-floating hybrid connector 20 are electrically contacted with each other, thereby establishing an electrical connection between the first circuit board P1 and the second circuit board P2.

[0096] Referring to Figure 5 and Figure 6 , the floating hybrid connector 10 according to an embodiment of the present application is described. As shown in Figure 5 and Figure 6 , the floating hybrid connector 10 includes a first housing 11 as a fixed housing, a second housing 12 as a movable housing, a plurality of signal contact pieces 13, and a plurality of power contact pieces 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 contact pieces 13 and the power contact pieces 14 are made of an electrically conductive material, such as copper or a copper alloy.

[0097] The first housing 11 is provided with a receiving space 110 in which a lower portion of the second housing 12 is received. A gap is left between the first housing 11 and the second housing 12 to allow the second housing 12 to move relative to the first housing 11 in a plane perpendicular to the first direction D1.

[0098] The second housing 12 is provided with a body portion 120 and limit blocks 121 formed at both ends of the body portion 120, respectively. The body portion 120 of the second housing 12 is formed with a mating slot 1200 as a mating portion. Two U-shaped metal fittings 15 are fitted at both end portions of the first housing 11 so as to interfere with the limit blocks 121. The movement of the second housing 12 in the first direction D1 is blocked by the U-shaped metal fittings 15, and the second housing 12 is prevented from being detached from the first housing 11. In this way, the second housing 12 is restricted to move relative to the first housing 11 only in a plane perpendicular to the first direction D1. Figure 7 ​A perspective view of the signal contacts 13 and the power contacts 14, one of the signal contacts 13 and one of the power contacts 14 being depicted enlarged. As shown, the signal contacts 13 and the power contacts 14 are arranged in two columns along a second direction D2 perpendicular to the first direction D1. The two columns of contacts are mirror-symmetrical to each other. In each column of contacts, two power contacts 14 are arranged on both sides of and spaced apart from a group of signal contacts 13 constituted by the signal contacts 13. However, the utility model is not limited thereto, and in each column of contacts, the two power contacts 14 can also be arranged on the same side of the group of signal contacts 13. Although in the present embodiment, only one power contact is arranged on each side of the group of signal contacts in each column of contacts, two or more power contacts can be arranged on each side of the group of signal contacts if necessary. Figure 7

[0099] In the present embodiment, the floating hybrid connector 10 is provided with 140 signal contacts 13 and 4 power contacts 14. However, the utility model is not limited thereto, and the number of signal contacts or power contacts can be increased or decreased as necessary.

[0100] Each signal contact 13 includes a signal-side solder 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 is continued from the signal-side solder portion 131. The signal-side spring portion 133 connects the first signal-side holding portion 132 and the second signal-side holding portion 134 and allows the second signal-side holding portion 134 to be elastically displaced relative to the first signal-side holding portion 132. The signal-side contact portion 135 is continued from the second signal-side holding portion 134. The signal-side solder portion 131 is to be fixed to a circuit board by surface mounting technology. The first signal-side holding portion 132 formed with a barb structure is press-fitted to the first housing 11 and held by the first housing 11. The second signal-side holding portion 134 formed with a barb structure is press-fitted to the second housing 12 and held by the second housing 12.

[0101] The signal-side spring portion 133 of the signal contact 13 sequentially includes a first extension portion 1331, a first curved portion 1332, a second extension portion 1333, a second curved portion 1334, and a third extension portion 1335. When viewed from the second direction D2, 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 a direction parallel to the first direction D1.

[0102] ​Each power contact 14 includes a power side solder portion 141, a first power side holding portion 142, a power side staggered extension portion 143, a second power side holding portion 144, and a power side contact portion 145. The first power side holding portion 142 is continued from the power side solder portion 141. The power side staggered extension portion 143 connects the first power side holding portion 142 and the second power side holding portion 144. The power side contact portion 145 is continued from the second power side holding portion 144. The power side solder portion 141 is to be fixed to a circuit board by surface mounting technology. The first power 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 side holding portion 144 formed with a barb structure is press-fitted to the second housing 12 and held by the second housing 12.

[0103] The power side staggered extension portion 143 of the power contact 14 includes, in order, 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 with respect to the first direction D1 when viewed from the second direction D2. The second extension portion 1433 includes a section that extends obliquely with respect to the first direction D1 when viewed from the third direction D3, so that the second power side holding portion 144 and the power side contact portion 145 are staggered with respect to the power side solder portion 141 and the first power side holding portion 142. In the present embodiment, the power side staggered extension portion 143 of the power contact 14 of the floating hybrid connector 10 functions as a power side spring portion, allowing the second power side holding portion 144 to be elastically displaced with respect to the first power side holding portion 142.

[0104] The signal side contact portion 135 of the signal contact 13 and the power side contact portion 145 of the power contact 14 are positioned in the fitting slot 1200 of the second housing 12 so as to be in contact with the contacts of a mating connector.

[0105] Figure 8 is Figure 7 A view of the power contact 14 as viewed from the third direction D3 is depicted enlarged in the center. Figure 9 is a view of the signal contact 13 and the power contact 14 as viewed from the third direction D3. As Figure 8As shown, the power contact 14 is configured such that the center axis C2 of the power side contact portion 145 is offset toward the left direction of the drawing (i.e. toward the inner direction) relative to the center axis C1 of the power side solder portion 141. In other words, by the power side offset extension portion 143, the center axis C2 of the power side contact portion 145 is offset toward the left direction of the drawing (i.e. toward the inner direction) relative to the center axis C1 of the power side solder portion 141 in the second direction D2, such that the gap between the power side solder portion 141 and the signal contact group is larger than the gap between the power side contact portion 145 and the signal contact group. This configuration allows the gap between the power contact and the signal contact at the substrate side to be different from the gap between the power contact and the signal contact at the contact side. As a result, as shown in FIG. 1, the gap between the power contact 14 and the signal contact group 13 at the substrate side is larger than the gap between the power contact 14 and the signal contact group 13 at the contact side. Figure 9 As shown, the power contact is configured such that the gap between the power contact and the signal contact at the substrate side is larger than the gap between the power contact and the signal contact at the contact side.

[0106] Because the temperature of the power side solder portion can rise when the power contact transmits power, the adjacent signal contact can be adversely affected. Once the temperature of the signal contact rises, its resistance characteristic can also change, causing the signal transmitted by the signal contact to attenuate. This can cause abnormal signal transmission. Therefore, the power contact of the present application can suppress the thermal effect on the signal contact, improving the reliability of signal transmission of the connector.

[0107] Because the power contact 14 has a larger width than the signal contact 13, the power side offset extension portion 143 of the power contact 14, which serves as a spring portion, has a larger stiffness than the signal side spring portion 133 of the signal contact 13. In order to facilitate the floating of the second housing, it is very advantageous to reduce the stiffness of the power side offset extension portion 143 of the power contact 14, making the power side offset extension portion 143 of the power contact 14 more easily deformable.

[0108] As can be seen in FIG. 1, the power side offset extension portion 143 of the power contact 14 is configured to have a larger width than the signal side spring portion 133 of the signal contact 13. Figure 7 、 Figure 8 The power side offset extension portion 143 of the power contact 14 is configured to have a plurality of elongated slots 1430 extending along the longitudinal direction thereof. The power side offset extension portion 143 is weakened by the formation of the elongated slots 1430.

[0109] The floating hybrid connector 10 further comprises a high frequency insulator 16. The high frequency insulator 16 is fixed at the bottom of the second housing 12. The high frequency insulator 16 is configured to partially surround the exposed portion of the signal contact 13, so as to improve the high frequency characteristic of the signal contact 13. For ease of illustration, only the signal contact 13 and the high frequency insulator 16 are shown in FIG. 1. Figure 10 Figure 10 ​As shown, the high-frequency insulator 16 includes a plurality of accommodation grooves 161. The accommodation grooves 161 are arranged at a predetermined pitch in the second direction. Each of the accommodation grooves 161 is provided to accommodate a portion of each of the signal contacts 13 adjacent to the second-signal-side holding portion 134.

[0110] Reference will now be made to Figure 11 and Figure 12 The non-floating hybrid connector 20 will be described in brief. Figure 11 A perspective view of the non-floating hybrid connector 20, Figure 12 is a perspective exploded view of the non-floating hybrid connector 20.

[0111] The non-floating hybrid connector 20 includes an insulating housing 21, a plurality of signal contacts 22, and a plurality of power contacts 23. The insulating housing 21 is a two-piece housing composed of a first housing 21A and a second housing 21B. Each of the first housing 21A and the second housing 21B 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 an electrically conductive material such as copper or a copper alloy. The insulating housing 21 serves as a fixed housing.

[0112] The first housing 21A is in the form of an outer frame, and one end of the second housing 21B is in the form of a tongue plate. The tongue plate serves as a fitting portion of the non-floating hybrid connector 20. The second housing 21B is arranged in the first housing 21A in a manner that it cannot move relative to the first housing 21A.

[0113] Figure 13 A perspective view of the signal contacts 22 and the power contacts 23. As shown, Figure 13 The signal contacts 22 and the power contacts 23 are arranged in two columns along a second direction D2 perpendicular to the first direction D1. The two columns of contacts are mirror-symmetrical to each other. In each column of contacts, two power contacts 23 are arranged on both sides of and spaced apart from a group of signal contacts 22 composed of signal contacts 22. However, the present application is not limited thereto. The contact layout of the non-floating hybrid connector can depend on the contact layout of the floating hybrid connector with which it is paired.

[0114] Each signal contact 22 includes: a signal-side solder portion 221, a first signal-side holding portion 222, a signal-side bent 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 solder portion 221. The signal-side bent 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 solder portion 221 is fixed to the circuit board using surface mount technology. The first signal-side holding portion 222 and the second signal-side holding portion 224, which have barbed structures, are press-fitted into and held by the second housing 21B.

[0115] Each power contact 23 includes: a power-side solder portion 231, a first power-side retaining portion 232, a power-side misaligned extension portion 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 solder portion 231. The power-side misaligned extension portion 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 solder portion 231 is fixed to the circuit board using surface mount technology. The first power-side retaining portion 232 and the second power-side retaining portion 234, which have barbed structures, are press-fitted into and held by the second housing 21B.

[0116] Figure 14 yes Figure 13 The enlarged depiction of the power contact 14 is shown in a third-party view from point D3. Figure 15 This is a view of signal contact 22 and power contact 23 from a third party to D3. For example... Figure 14 As shown, the power contact 23 is configured such that the central axis C4 of the power-side contact portion 235 is offset relative to the central axis C3 of the power-side solder portion 231 in the left direction (i.e., inward direction) of the drawing. In other words, through the power-side offset extension 233, the central axis C4 of the power-side contact portion 235 is offset relative to the central axis C2 of the power-side solder portion 231 in the second direction D2 in the left direction (i.e., inward direction) of the drawing, such that the gap between the power-side solder portion 231 and the signal contact group is greater than the gap between the power-side contact portion 235 and the signal contact group. Figure 15 As shown, by means of the power-side contact portion 235 being misaligned relative to the power-side solder portion 231, the gap between the power-side solder portion 231 and the signal contact group is made larger than the gap between the power-side contact portion 235 and the signal contact group.

[0117] It should be appreciated that although the insulating housing 21 is a two-piece housing in the present embodiment, the present application is not limited thereto. The insulating housing 21 can be made into a single-piece housing. Although the signal contact and the power contact are held by the second housing 21B only in the present embodiment, the present application is not limited thereto. In the case of a two-piece housing, the signal contact and the power contact can be held by the first housing and the second housing.

[0118] Furthermore, the hybrid connector according to the present application can be embodied as a floating hybrid connector or a non-floating hybrid connector.

[0119] Although the present application is described and illustrated with reference to the preferred embodiments, it should be understood that numerous changes and modifications can be made to the application by those skilled in the art without departing from the true spirit and scope of the application. Therefore, the present application is not limited to the embodiments described herein but should be construed to cover all changes and modifications that fall within the true spirit and scope of the application.
