Description

Technical Field

[0001] This invention relates to a connector assembly, and more particularly to a connector assembly with a heat sink. Background Technology

[0002] Chinese Invention Patent Publication No. CN110296628A (corresponding to US Patent Publication No. US10,651,598B2) discloses a heat exchange structure comprising a metal component, a lever, and a frame. The frame supports the lever and the metal component, and the front end of the metal component is fixed to the front edge of the frame by fasteners such as rivets. When a heat source slides relative to a radiator, the heat source contacts one end of the lever, causing the other end of the lever to contact the rear end of the metal component. The metal component then pushes the radiator and its thermal pads into contact with the heat source. However, this prior art requires an additional frame to mount the lever and the metal component. Furthermore, the metal component needs to be located on top of the radiator, necessitating a groove in the top of the radiator to accommodate it, thus reducing the radiator's heat dissipation area. Additionally, the metal component is only connected to the radiator at a single point (screw), and the lever is pushed against the rear end of the metal component, a design that makes the radiator prone to tilting. Summary of the Invention

[0003] Therefore, one object of the present invention is to provide a connector assembly that can improve upon at least one of the disadvantages of the prior art.

[0004] Therefore, in some embodiments, the connector assembly of the present invention includes a housing, a receptacle connector, a pluggable module, a heat sink, and a pressure-applying member. The housing has an internal insertion space and a top wall constituting the insertion space, the top wall having a window. The receptacle connector is disposed within the insertion space of the housing. The pluggable module is used to insert into the insertion space of the housing to mate with the receptacle connector. The heat sink has a downwardly protruding thermal coupling portion and a pushed-out portion, as well as a main spring actuation portion, the thermal coupling portion having a thermal coupling surface at its bottom. The pressure-applying member assembles the radiator to the top wall of the cover and enables the radiator to move relative to the cover between a non-operating position in the front and an operating position in the rear. The pressure-applying member has an assembly portion assembled to the cover and a main spring portion. When the pluggable module is inserted into the insertion space of the cover, the pluggable module pushes the push-receiving protrusion of the radiator to move the radiator from the non-operating position to the operating position. When the radiator is in the operating position, the main spring portion of the radiator contacts the main spring portion of the pressure-applying member, and the main spring portion of the pressure-applying member acts on the main spring portion of the radiator to provide a downward force so that the thermal coupling surface of the radiator contacts the surface of the pluggable module with a positive force through the window.

[0005] In some embodiments, the thermal coupling surface of the heat sink's thermal coupling portion is provided with a thermal interface material.

[0006] In some embodiments, when the radiator is in the non-operating position, the main spring portion of the radiator does not contact the main spring portion of the pressure-applying member.

[0007] In some embodiments, the radiator further has side plates located on both sides, the side plates having the main spring action portion having a main spring action surface extending rearward and downward at an angle, and the pressure-applying member having two main spring portions for acting on the main spring action surface of the main spring action portion.

[0008] In some embodiments, the cover also has sidewalls that together with the top wall form the insertion space, the pressure-applying member has a frame having a front frame, a rear frame and two side frames, the assembly part extends downward from the side of the frame and is assembled to the sidewall of the cover, and each side frame has a main spring part extending backward and downward at an angle.

[0009] In some embodiments, the radiator further has an auxiliary spring actuation portion, and the pressure-applying member further has an auxiliary spring portion. When the radiator is in the non-acting position, the auxiliary spring portion applies downward pressure to the auxiliary spring actuation portion, and the thermal coupling surface of the radiator enters the insertion space through the window.

[0010] In some embodiments, the side plate is further provided with auxiliary spring action parts located in front of and behind the main spring action part, and the pressure-applying member is further provided with auxiliary spring parts forming elastic foot structures downward from both ends of the front frame and both ends of the rear frame. When the radiator is in the non-operational position, the auxiliary spring parts apply downward pressure to the auxiliary spring action part, and the thermal coupling surface of the radiator enters the insertion space through the window.

[0011] In some embodiments, a support spring is provided between the top wall of the cover and the radiator, and when the radiator is in the non-operational position, the support spring lifts the radiator upward.

[0012] In some embodiments, the thermal coupling surface of the heat sink does not contact the surface of the pluggable module before the pluggable module pushes the pushed protrusion of the heat sink to move the heat sink to the operating position.

[0013] In some embodiments, the top wall of the enclosure has a spring-shaped support spring integrally formed next to the window.

[0014] The pressure-applying member of the connector assembly of the present invention is not only used for assembling the heat sink, but also provides a main spring portion that can act on the heat sink. Furthermore, the main spring portion of the pressure-applying member applies a force to the heat sink, causing the thermal coupling surface of the heat sink to contact the surface of the pluggable module, only after the heat sink is pushed backward by the pluggable module. This reduces the friction between the thermal coupling surface of the heat sink and the pluggable module during the insertion of the pluggable module, thereby preventing wear on the thermal coupling surface of the heat sink or scratches on the thermal interface material provided on the thermal coupling surface of the heat sink.

[0096] Before the invention is described in detail, it should be noted that similar elements are represented by the same numbers in the following description.

[0097] See Figures 1 to 3A first embodiment of the connector assembly 100 of the present invention includes a housing 1, a socket connector 2, a pluggable module 3, a heat sink 4, a pressure-applying member 5, two light guides 6, and a connector 7 for the light guides. It should be noted that the quantities of the housing 1, the socket connector 2, the heat sink 4, the pressure-applying member 5, the light guides 6, and the connector 7 for the light guides can all be adjusted according to requirements and can be stacked or combined, and are not limited to the quantities in this first embodiment.

[0098] The cover 1 is, for example, constructed from a thin metal sheet by stamping and bending using a mold. The cover 1 is used to mount a circuit board (not shown) and extends along a front-to-back direction D1 (arrow direction is front, reverse direction is rear). The cover 1 has a top wall 11, a bottom wall 12 spaced from the top wall 11 along a vertical direction D2 (arrow direction is up, reverse direction is down), two side walls 13 spaced along a left-to-right direction D3 (arrow direction is right, reverse direction is left) and connected between the top wall 11 and the bottom wall 12, a rear wall 14 connected to the rear edges of the top wall 11 and the two side walls 13, and a plurality of pins 15 extending downward from the two side walls 13 and adapted for fixing on the circuit board and / or connecting to a grounding track (not shown). In addition, the cover 1 also has a plug-in space 16 defined and located inside by the top wall 11, the bottom wall 12, the two side walls 13 and the rear wall 14, a front plug-in port 161 located at the front end and connected to the plug-in space 16 for the pluggable module 3 to be inserted, a window 162 formed on the top wall 11 and extending rearward from the front end of the top wall 11 and connected to the plug-in space 16, and a bottom opening 163 located behind the bottom wall 12 and connected to the plug-in space 16.

[0099] The socket connector 2 (see) Figure 1 The receptacle connector 2 is mechanically and electrically disposed on the circuit board. It has an insulated base 21 and a plurality of terminals 22. The base 21 has a insertion slot 211, and the terminals 22 are disposed within the insertion slot 211, with their tails (not shown) electrically and mechanically connected to the circuit board. The receptacle connector 2 is covered by the cover 1 through the bottom opening 163, so that the receptacle connector 2 is located at the rear of the insertion space 16, but this is not a limitation.

[0100] The pluggable module 3 includes a housing 31, a connector plate 32, and a cable (not shown). The housing 31 includes a connector portion 311. The connector plate 32 protrudes from the connector portion 311 and has a plurality of contact fingers 321. The cable is disposed in the housing 31 and is mechanically and electrically connected to the connector plate 32. After the pluggable module 3 enters the housing 1 through the front socket 161, the connector plate 32 at the end of the connector portion 311 of the pluggable module 3 can be inserted into the connector slot 211 of the socket connector 2, so that the contact fingers 321 of the connector plate 32 contact the terminals 22 in the connector slot 211 of the socket connector 2, thereby enabling the pluggable module 3 and the socket connector 2 to mate with each other. In addition, a mounting hole can be provided in a housing (not shown) near the front end of the cover 1 adjacent to the front end socket 161. The front end socket 161 of the cover 1 is also provided with a plurality of grounding members 17. The grounding members 17 have a plurality of elastic fingers 171 extending rearward from the front end socket 161 and distributed on the outer side and the inner side of the cover 1. The elastic fingers 171 located on the outer side of the cover 1 are used to partially contact the periphery of the mounting hole of the housing, and the elastic fingers 171 located on the inner side of the cover 1 are used to contact the pluggable module 3.

[0101] See Figures 1 to 4 The heat sink 4 is located on the top wall 11 of the cover 1. The heat sink 4 has a base plate 41 located on the top wall 11, a plurality of heat dissipation fins 42 that are arranged side by side along the left-right direction D3 and integrally extended upward from the top surface of the base plate 41, and a plurality of side plates 43 that are connected to the left and right sides of the base plate 41 and are spaced apart from the heat dissipation fins 42. The bottom surface of the substrate 41 has a downwardly protruding thermal coupling portion 411 for extending into the insertion space 16 from the window 162, a downwardly protruding guide portion 412 located in front of the thermal coupling portion 411, and a push-receiving protrusion 413 disposed at the rear end of the thermal coupling portion 411. The thermal coupling portion 411 has a thermal coupling surface 411a located at the bottom. The push-receiving protrusion 413 is columnar, protruding downward from the thermal coupling surface 411a, and extends into the insertion space 16 from the rear end of the window 162. In this first embodiment, a thermal interface material 411b (see...) is provided on the thermal coupling surface 411a. Figure 4The thermal interface material 411b can fully fill the seams or gaps of the contact surface to reduce the contact thermal resistance between the contact surfaces. The thermal interface material 411b can be selected from a combination of materials with properties such as high thermal conductivity, high flexibility, compressibility, insulation, and wear resistance. For example, it can be a combination of a substrate and a phase change material. For example, it can have a two-layer or more structure, where the outer substrate can be a material with thermal conductivity, lubricity, wear resistance, and tear resistance (e.g., Teflon), and the inner material is a phase change material. In addition, the thermal interface material 411b can also have electromagnetic wave shielding (EMI shielding) by changing the combination of materials. In addition, in this first embodiment, the side plate 43 has an outwardly protruding auxiliary heat sink 431 on the portion above the substrate 41, which is arranged side by side along the vertical direction D2.

[0102] The pressure-applying member 5 assembles the radiator 4 to the top wall 11 of the cover 1. The pressure-applying member 5 has a frame 51 and four assembly parts 52 extending downward from the left and right sides of the frame 51 and assembled to the two side walls 13 of the cover 1. The frame 51 has a front frame 511 and a rear frame 512 spaced side by side along the front-rear direction D1, and two side frames 513 connected to the front frame 511 and the rear frame 512 and spaced side by side along the left-right direction D3. Specifically, each side wall 13 of the cover 1 forms two fastening protrusions 131, and each assembly part 52 forms a fastening hole 521 that fastens to the corresponding fastening protrusion 131 of the side wall 13. The fastening protrusions 131 and the fastening holes 521 are used to assemble these assembly parts 52 to the side wall 13 of the cover 1. The radiator 4 also has two main spring action parts 44 located on the left and right sides and disposed on the side plates 43, and four auxiliary spring action parts 45 disposed on the side plates 43 and located in front of and behind the two main spring action parts 44, respectively. Each main spring action part 44 has a main spring action surface 441 extending rearward and downward at an angle. The pressure-applying member 5 also has two main spring parts 53 disposed on the two side frames 513 and extending rearward and downward at an angle, and a plurality of auxiliary spring parts 54 formed by bending downward and forward or backward from both ends of the front frame 511 and both ends of the rear frame 512, forming an elastic foot structure. The two main spring parts 53 correspond to the main spring action surfaces 441 of the two main spring action parts 44, and the auxiliary spring parts 54 correspond to the auxiliary spring action parts 45.

[0103] See Figure 1 , Figures 4 to 7The pressure-applying member 5 allows the radiator 4 to be positioned relative to the cover 1 in a non-operating position (e.g., in front of it). Figure 4 and Figure 5 (as shown) and a position of action located at the rear (such as) Figure 6 and Figure 7 In this first embodiment, the radiator 4 also has two limiting grooves 46 formed on the heat dissipation fins 42 and respectively accommodating the front frame 511 and rear frame 512 of the pressure-applying member 5. The two limiting grooves 46 can limit the position of the radiator 4 in the front-rear direction D1 between the front frame 511 and rear frame 512 of the pressure-applying member 5. When the radiator 4 is in the non-operating position, the rear edge of the two limiting grooves 46 can abut against the front frame 511 and rear frame 512 of the pressure-applying member 5 in the forward direction. When the radiator 4 is in the operating position, the front edge of the two limiting grooves 46 can abut against the front frame 511 and rear frame 512 of the pressure-applying member 5 in the rearward direction. However, the radiator 4 can also be limited by other limiting structures provided on the cover 1 and / or the pressure-applying member 5, and is not limited to this first embodiment.

[0104] like Figure 4 and Figure 5 As shown, when the radiator 4 is in the non-operational position, the auxiliary spring portions 54 press downward on the auxiliary spring action portions 45, and the thermal coupling surface 411a of the radiator 4 enters the insertion space 16 through the window 162 of the top wall 11. At this time, the main spring action portion 44 of the radiator 4 does not contact the main spring portion 53 of the pressure member 5, and the main spring portion 53 of the pressure member 5 does not act on the main spring action portion 44 of the radiator 4. When the pluggable module 3 is inserted into the insertion space 16 of the housing 1, the pluggable module 3 will first push the guide portion 412 of the heat sink 4, so that the heat sink 4 overcomes the force provided by the auxiliary spring portions 54 and rises upward. Then, the thermal interface material 411b on the thermal coupling surface 411a of the heat sink 4 will contact the upper surface of the pluggable module 3. At this time, the main spring action portion 44 of the heat sink 4 still does not contact the main spring portion 53 of the pressure applying member 5, and the main spring portion 53 of the pressure applying member 5 does not act on the main spring action portion 44 of the heat sink 4. Figure 6 and Figure 7As shown, finally, when the pluggable module 3 pushes the push-receiving protrusion 413 of the heat sink 4 backward and reaches the contact point with the socket connector 2, the heat sink 4 moves backward from the non-operating position to the operating position. It should be noted that after the push-receiving protrusion 413 of the heat sink 4 is pushed backward, the push-receiving protrusion 413 will be accommodated in a rear recess 162a at the rear end of the window 162. When the heat sink 4 is in the operating position, the main spring actuating part 44 of the heat sink 4 contacts the main spring part 53 of the pressure applying member 5, and the main spring part 53 of the pressure applying member 5 acts on the main spring actuating surface 441 of the main spring actuating part 44 of the heat sink 4 to provide a downward force so that the thermal interface material 411b on the thermal coupling surface 411a of the heat sink 4 contacts the upper surface of the pluggable module 3 with a positive force through the window 162. In general, in this first embodiment, the heat sink 4 moves from the non-functional position upward and backward to the functional position during the insertion of the pluggable module 3. Additionally, it should be noted that in a variant embodiment, the thermal coupling surface 411a of the heat sink 4 may directly contact the upper surface of the pluggable module 3 without passing through the thermal interface material 411b.

[0105] Furthermore, due to the inclined structure of the main spring part 44 of the radiator 4 and the main spring part 53 of the pressure-applying member 5, when the radiator 4 is in the active position, the main spring part 53 of the pressure-applying member 5 provides not only a downward force to the radiator 4, but also a forward force to the radiator 4. Therefore, when the pluggable module 3 is removed from the insertion space 16 of the cover 1, the force of the main spring part 53 of the pressure-applying member 5 and the friction of the pluggable module 3 will cause the radiator 4 to move forward, and the auxiliary spring part 54 of the pressure-applying member 5 will cause the radiator 4 to move downward, so that the radiator 4 moves from the active position to the non-active position.

[0106] During this process, the main spring portion 53 of the pressure-applying member 5 provides a larger force that ensures close contact between the thermal coupling portion 411 of the heat sink 4 and the surface of the pluggable module 3, while the auxiliary spring portion 54 of the pressure-applying member 5 provides a smaller pre-force that ensures the thermal coupling portion 411 of the heat sink 4 enters the insertion space 16 through the window 162. Furthermore, since the main spring portion 53 of the pressure-applying member 5 only applies a force to the heat sink 4 after the heat sink 4 has been pushed backward by the pluggable module 3, ensuring close contact between the thermal coupling surface 411a of the heat sink 4 and the surface of the pluggable module 3, friction between the thermal coupling surface 411a of the heat sink 4 and the pluggable module 3 during insertion of the pluggable module 3 can be reduced. This prevents wear on the thermal coupling surface 411a of the heat sink 4 or scratches on the thermal interface material 411b provided on the thermal coupling surface 411a of the heat sink 4.

[0107] The heat sink 4 also has two light guide mounting slots 47 defined by the heat dissipation fins 42 and the two side plates 43 and extending along the front-rear direction D1. The cover 1 also has two front mounting plates 18 located near the front end and extending upward from the two side walls 13, and two rear mounting plates 19 located at the rear end and extending rearward from the two side walls 13. The two light guides 6 are disposed on the cover 1 and respectively housed in the two light guide mounting slots 47. Each light guide 6 has two light guide tubes 61, a front mounting post 62 connected to the two light guide tubes 61 and extending downward, a rear mounting post 63 connected to the two light guide tubes 61 and extending downward, and a rear connecting post 64 connected to the two light guide tubes 61. Each light guide tube 61 has a downward-facing light-incident end 611 facing the light-emitting element of the circuit board, and a forward-facing light-emitting end 612. The front mounting post 62 is disposed on the corresponding front mounting piece 18 of the housing 1, and the rear mounting post 63 is disposed on the corresponding rear mounting piece 19 of the housing 1. The front mounting piece 18 has a tenon groove 181, the front mounting post 62 has a tenon block 621 for tenoning into the tenon groove 181, and the rear mounting post 63 has an insertion hole 631 for inserting the rear mounting piece 19, thereby assembling the two light guide tubes 61 onto the housing 1.

[0108] The light guide connector 7 is disposed between the two light guides 6 and the light-emitting elements of the circuit board. The light guide connector 7 has multiple receiving holes 71, each receiving hole 71 having its two ends receiving the light-incident end 611 of the light guide tube 61 of the corresponding light guide 6 and the corresponding light-emitting element, ensuring that the light emitted by these light-emitting elements can enter the light-incident end 611 of the light guide tube 61 of the corresponding light guide 6. Furthermore, each light guide 6 has a rear connecting post 64 with an inner slot 641. The light guide connector 7 also has two hooks 72 that are locked from the inside out into the slot 641 of the corresponding light guide 6, and a positioning post 73 for passing through the circuit board, thereby fixing the light guide connector 7 between the two light guides 6 and the circuit board.

[0109] See Figures 8 to 10 The second embodiment of the connector assembly 100 of the present invention differs from the first embodiment in that a plurality of support springs 8 are provided between the top wall 11 of the cover 1 and the substrate 41 of the heat sink 4. Furthermore, in this second embodiment, the top wall 11 of the cover 1 has these support springs 8 in the form of spring sheets integrally formed next to the window 162. However, it should be noted that in other embodiments, these support springs 8 may also be integrally formed on the heat sink 4, or these support springs 8 may be independent components.

[0110] When the heat sink 4 is in the non-operational position, the support spring 8 raises the heat sink 4 upwards, spacing the base plate 41 of the heat sink 4 from the top wall 11 of the cover 1, and preventing the thermal coupling surface 411a of the heat sink 4 from entering the insertion space 16 of the cover 1. At this time, the main spring action part 44 of the heat sink 4 does not contact the main spring part 53 of the pressure member 5, and the main spring part 53 of the pressure member 5 does not act on the main spring action part 44 of the heat sink 4. When the pluggable module 3 (see...) Figure 1 During the insertion into the insertion space 16 of the cover 1 and before pushing the pushed protrusion 413, the main spring actuation part 44 of the heat sink 4 does not contact the main spring part 53 of the pressure member 5, and the main spring part 53 of the pressure member 5 does not act on the main spring actuation part 44 of the heat sink 4. Therefore, at this time, the thermal coupling surface 411a of the heat sink 4 does not enter the insertion space 16 of the cover 1 and contact the pluggable module 3. Finally, when the pluggable module 3 pushes the pushed protrusion 413 of the heat sink 4 and reaches the socket connector 2 (see Figure 1 During the docking process, the radiator 4 moves backward from the non-operational position to the operational position. When the radiator 4 is in the operational position, the main spring action part 44 of the radiator 4 contacts the main spring part 53 of the pressure member 5, and the main spring part 53 of the pressure member 5 acts on the main spring action surface 441 of the main spring action part 44 of the radiator 4 to provide a downward force to press the radiator 4 down, so that the thermal coupling surface 411a of the radiator 4 enters the insertion space 16 of the cover 1 through the window 162, and the thermal interface material 411b on the thermal coupling surface 411a of the radiator 4 contacts the upper surface of the pluggable module 3 with a positive force. In other words, before the pluggable module 3 pushes the push-received protrusion 413 of the heat sink 4 to move the heat sink 4 to the operating position, the thermal coupling surface 411a of the heat sink 4 does not contact the surface of the pluggable module 3. This further prevents wear on the thermal coupling surface 411a of the heat sink 4, or scratches on the thermal interface material 411b provided on the thermal coupling surface 411a of the heat sink 4. Overall, in this second embodiment, the heat sink 4 moves from the non-operating position backward and downward to the operating position during the insertion of the pluggable module 3.

[0111] In addition, when the pluggable module 3 is removed from the insertion space 16 of the cover 1, the force of the main spring part 53 of the pressure member 5 and the friction of the pluggable module 3 will cause the heat sink 4 to move forward, and the support springs 8 will cause the heat sink 4 to move upward, so that the heat sink 4 moves from the active position to the non-active position.

[0112] In summary, the pressure-applying member 5 of the connector assembly 100 of the present invention is not only used for assembling the heat sink 4, but also provides a main spring portion 53 that can act on the heat sink 4. Furthermore, the main spring portion 53 of the pressure-applying member 5 provides a force to the heat sink 4 after the heat sink 4 is pushed backward by the pluggable module 3, so that the thermal coupling surface 411a of the heat sink 4 contacts the surface of the pluggable module 3. This can reduce the friction between the thermal coupling surface 411a of the heat sink 4 and the pluggable module 3 during the insertion of the pluggable module 3, thereby preventing wear of the thermal coupling surface 411a of the heat sink 4 or scratching of the thermal interface material 411b provided on the thermal coupling surface 411a of the heat sink 4.

[0113] However, the above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and patent specification of the present invention shall still fall within the scope of the patent of the present invention.
