Description

Connector Assemblies

The present invention relates to a connector, and more particularly to a connector assembly.

Chinese invention patent publication number CN110296628A (corresponding to US invention patent number US10651598B2) discloses a heat exchange structure, which includes a metal part, a lever, and a frame, the frame is used to support the lever and the metal part, and the front end of the metal part is fixed to the front edge of the frame by fasteners such as rivets. When the heat source slides relative to the heat sink, the heat source contacts one end of the lever to actuate the other end of the lever to contact the rear end of the metal part, and the metal part pushes the heat sink and the thermal pad downward to contact the heat source.

However, this prior art requires an additional frame to install the lever and metal parts. Moreover, the metal parts need to be placed on the top surface of the radiator, which requires the radiator to have a groove for installing the metal parts, reducing the heat dissipation area of the radiator. In addition, the metal parts are only connected to the radiator at a single point (screw), and the lever is pressed on the rear end of the metal parts when it is pushed, which makes the radiator easily tilted. Furthermore, the metal parts need space to allow them to deform and move elastically up and down, and the lever needs space up and down and front and back to allow it to rotate and swing, so it occupies a lot of space in the radiator and it is difficult to make the overall radiator thinner.

Referring to FIGS. 1 to 5 , the heat sink frame 12 of the cage 1 is disposed on the top wall 111 of the shell 1 of the cage 1 above the insertion passage 11a. The shell 11 has a first assembly structure 116 for assembly to the heat sink frame 12, and the heat sink frame 12 has an upper wall 121 and a lower wall 122 opposite to each other along the up-down direction D2, a front connecting wall 123 connected between the front edge of the upper wall 121 and the front edge of the lower wall 122, two side walls 124 extending downward from the left and right side edges of the upper wall 121, and a second assembly structure 125 for assembly corresponding to the first assembly structure 116.

The first assembly structure 116 includes two front assembly pieces 116a extending upward from the front sections of the two side walls 113 and each having a front limit groove 116b opening forward, two rear assembly pieces 116c extending upward from the rear sections of the two side walls 113 and each having a rear limit groove 116d opening forward, two insertion holes 116e formed on the two side walls 113 and opening forward, and a positioning buckle hole 116f formed on the top wall 111 behind the window 11c and extending along the left-right direction D3. The second assembly structure 125 includes two front limiting pieces 125a extending outward from the front sections of the two side edges of the lower wall 122 and snapping backward into the two front limiting grooves 116b, two rear limiting pieces 125b extending outward from the rear sections of the two side edges of the lower wall 122 and snapping backward into the two rear limiting grooves 116d, two inserting pieces 125c extending downward and backward from the two side walls 124 and snapping backward into the two insertion holes 116e, and a positioning buckle piece 125d formed at the rear end of the lower wall 122 and snapping downward into the positioning buckle hole 116f.

The two inserting pieces 125c respectively inserted into the two insertion holes 116e can limit the position of the radiator frame 12 relative to the housing 11 in the left-right direction D3 and the vertical direction D2. In addition, the radiator frame 12 can be positioned relative to the housing 11 in the front-rear direction D1 through the cooperation of the positioning buckle 125d and the positioning buckle hole 116f. The lower wall 122 is formed with two slits 122a on the left and right sides of the positioning buckle 125d. The positioning buckle 125d can be flexibly moved through the two slits 122a. Therefore, in the process of assembling the radiator frame 12 to the housing 11, the positioning buckle 125d can first be flexibly moved upward to cross the top wall 111 from the window 11c, and then reset downward and buckled downward into the positioning buckle hole 116f.

The heat sink frame 12 further comprises a heat sink accommodating space 126 defined by the upper wall 121, the lower wall 122, the front connecting wall 123 and the two side walls 124, and a lower opening 127 formed on the lower wall 122 and connected to the heat sink accommodating space 126 and corresponding to the window 11c of the housing 11.

The heat sink 42 is located below the moving plate 41. The heat sink 42 has a base plate 421 and a plurality of heat sink fins 422 that are arranged side by side along the left-right direction D3 and extend upward from the top surface of the base plate 421. The substrate 421 has a through hole 421a for the pushed portion 411 of the moving plate 41 to pass through, and a thermal coupling portion 421b located at the bottom and protruding downward and used to pass downward through the lower opening 127 and the window 11c to extend into the plug-in channel 11a. In the first embodiment, the thermal coupling portion 421b has a protruding block 421c protruding downward, and a thermal pad 421d provided on the bottom surface of the protruding block 421c. For example, the thermal pad 421d can be a thermal interface material. The thermal interface material (Thermal Interface The thermal interface material 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 can be selected from a combination of materials with high thermal conductivity, high flexibility, compressibility, insulation, wear resistance and other properties, and for example, it can be a combination of a substrate and a phase change material. For example, it can be a structure of more than two layers, and its outer substrate can be a material with thermal conductivity, lubricity, wear resistance, and tear resistance (such as Teflon), while its inner layer material is a phase change material. In addition, the thermal interface material can also have an electromagnetic wave shielding effect (EMI Shielding) through the combination of materials.

The movable plate 41 can move along the front-rear direction D1 between a first position at the front (see FIG. 6 ) and a second position at the rear (see FIG. 8 ) relative to the heat sink frame 12. The heat sink 42 can move along the up-down direction D2 between a release position at the top (see FIG. 6 ) and a contact position at the bottom (see FIG. 8 ) relative to the heat sink frame 12. Specifically, in the first embodiment, a heat sink guide structure is provided between the heat sink 42 and the heat sink frame 12, and the heat sink guide structure includes two guide holes 124b constructed on the two side walls 124 of the heat sink frame 12, and two guide protrusions 423 constructed on the left and right sides of the heat sink 42 and correspondingly arranged in the two guide holes 124b so as to be movably arranged along the up-down direction D2. By the cooperation between the two guide protrusions 423 and the two guide holes 124b, the movement of the heat sink 42 in the front-to-back direction D1 is restricted, and the heat sink 42 can move up and down between the upper release position and the lower contact position along the up-down direction D2 relative to the heat sink frame 12.

The pressure spring 43 is disposed between the moving plate 41 and the radiator 42. In the first embodiment, the pressure spring 43 is integrally constructed on the moving plate 41, and the radiator frame 12 is constructed with the pressure spring action structure 44. The pressure spring 43 includes a plurality of leaf spring portions 431 constructed on both sides of the moving plate 41 and arranged front and back, each leaf spring portion 431 includes a bottom portion 431a and an elastic arm 431b extending obliquely from the bottom portion 431a toward the front and upward direction, and the bottoms of the leaf spring portions 431 press downward against the radiator 42. The pressure spring action structure 44 includes a plurality of interference pieces 441 which are constructed on the upper wall 121 of the heat sink frame 12 and protrude downward, and the interference pieces 441 correspond to the leaf spring portions 431 respectively.

The two return springs 45 are disposed between the radiator frame 12 and the moving plate 41, and are used to provide an elastic force for the moving plate 41 to move to the first position. The radiator frame 12 has two first hooks 128 at the front end, and the moving plate 41 has two second hooks 412 at the front end.

The support spring 46 elastically supports the heat sink 42 upward and is used to provide an elastic force for the heat sink 42 to move to the release position. The support spring 46 includes two support spring structures 461, which are integrally constructed on the lower wall 122 on the left and right sides of the lower opening 127 of the heat sink frame 12 (close to the inner side of the side wall 124) and support the left and right sides of the heat sink 42 upward. Each of the supporting spring structures 461 includes two plate-shaped elastic supporting portions 461a that support the heat sink 42 upward. The two elastic supporting portions 461a extend obliquely upward, forward and backward, respectively.

1 , 3 , and 6 to 9 , the matching relationship between the pluggable module 3 and the heat sink module 4 is described below.

As shown in FIG6 , before the pluggable module 3 is inserted into the insertion channel 11a of the housing 1, the moving plate 41 is located at the first position due to the elastic force provided by the two return springs 45. The heat sink 42 is located at the release position due to the elastic force provided by the support spring 46. At this time, the interference piece 441 of the pressure spring action structure 44 constructed on the heat sink frame 12 is respectively located behind the plate spring part 431 of the pressure spring 43 constructed on the moving plate 41. In addition, in one embodiment, the interference piece 441 of the pressure spring action structure 44 constructed on the radiator frame 12 can also act forward on the plate spring portion 431 of the pressure spring 43 constructed on the movable plate 41 and in an inclined shape. Therefore, the movable plate 41 is also maintained in the first position through the action between the pressure spring action structure 44 and the pressure spring 43.

As shown in FIGS. 7 to 9, when the pluggable module 3 is inserted into the insertion channel 11a of the cage 1 along the insertion direction from front to back, the pushed portion 411 of the moving plate 41 is pushed backward, and the moving plate 41 is moved backward from the first position to the second position. At this time, the leaf spring portion 431 of the pressure spring 43 of the moving plate 41 is acted downward by the interference piece 441 of the pressure spring action structure 44 of the radiator frame 12, so that the moving plate 41 includes not only the backward movement but also the downward movement, and further the leaf spring portion 431 of the pressure spring 43 of the moving plate 41 links the radiator 42 downward from the release position. When the heat sink 42 moves to the contact position, the elastic force of the pressure spring 43 causes the thermal coupling portion 421b at the bottom of the heat sink 42 to face downward and contact the surface of the plug-in portion 311 of the pluggable module 3 with pressure, and in this state, the force of the plate spring portion 431 of the pressure spring 43 pushing the heat sink 42 downward is greater than the force of the support spring 46 supporting the heat sink 42 upward, the support spring 46 is compressed, and provides an elastic force for driving the heat sink 42 to return to the release position, and the two return springs 45 are stretched and provide an elastic force for driving the moving plate 41 to return forward to the first position.

When the pluggable module 3 is withdrawn from the plug-in channel 11a, the elastic force provided by the support spring 46 lifts the heat sink 42 upward to the release position where it does not contact the surface of the pluggable module 3. The interference piece 441 of the pressure spring action structure 44 of the heat sink frame 12 also acts forward on the plate spring portion 431 of the pressure spring 43 constructed on the moving plate 41. The pressure spring 43 drives the moving plate 41 to move forward, and the elastic force provided by the two return springs 45 causes the moving plate 41 to move forward and return to the first position.

It should be noted that, when the heat sink 42 is in the release position, the thermal coupling portion 421b at the bottom of the heat sink 42 may not extend into the plug-in channel 11a as in the first embodiment, or may extend into the plug-in channel 11a but be located at a height that does not contact the upper surface of the pluggable module 3. Therefore, before the pluggable module 3 pushes the moving plate 41, there is a gap between the thermal coupling portion 421b at the bottom of the heat sink 42 and the upper surface of the pluggable module 3.

10 to 13 , a second embodiment of the connector assembly 100 of the present invention is different from the first embodiment in that the pressure spring 43 and the movable plate 41 are separate components, and the pressure spring 43 is assembled on the heat sink 42. The pressure spring 43 includes two fixing portions 432 extending along the front-rear direction D1 and assembled on both sides of the heat sink 42 by, for example, welding or buckling, and a plurality of leaf spring portions 431′ integrally constructed on the two fixing portions 432 and arranged in a front-rear direction. The leaf spring portions 431′ of the pressure spring 43 extend obliquely backward and upward. The moving plate 41 is configured with the pressure spring action structure 44, and the pressure spring action structure 44 includes a plurality of interference pieces 441' configured on both sides of the moving plate 41 and protruding downward. In the second embodiment, the moving plate 41 is limited between the heat sink 42 and the heat sink frame 12, so the moving plate 41 is basically translated backward from the first position to the second position.

As shown in FIG12 , when the movable plate 41 is located at the first position, the radiator 42 is located at the release position due to the elastic force provided by the supporting spring 46, and the interference piece 441' of the pressure spring action structure 44 constructed on the movable plate 41 is respectively located in front of the plate spring portion 431' of the pressure spring 43 assembled on the radiator 42. As shown in FIG13 , when the moving plate 41 is pushed by the pluggable module 3 (see FIG1 ) and moves backward from the first position to the second position, the interference piece 441′ of the pressure spring action structure 44 constructed on the moving plate 41 acts downward on the plate spring portion 431′ of the pressure spring 43 assembled on the heat sink 42, thereby causing the pressure spring 43 to move downward from the release position to the contact position in conjunction with the heat sink 42. It should be noted that when the pluggable module 3 is withdrawn from the plug-in channel 11a, the plate spring portion 431' of the pressure spring 43 assembled on the heat sink 42 and in an inclined shape will also act forward on the interference piece 441' of the pressure spring action structure 44 constructed on the moving plate 41. Therefore, the moving plate 41 is moved forward through the action between the pressure spring action structure 44 and the pressure spring 43, and the elastic force provided by the two return springs 45 causes the moving plate 41 to move forward and return to the first position.

In addition, in the second embodiment, the two supporting spring structures 461 of the supporting spring 46 are in the form of independent components and are assembled to the heat sink frame 12 by, for example, welding or buckling. Furthermore, it should be noted that the two side walls 124 of the heat sink frame 12 are respectively assembled to the two side assembly parts 122b extending upward of the lower wall 122, each of the side walls 124 has a buckling hole 124a, and each side assembly part 122b of the lower wall 122 has a buckling piece 122c assembled to the buckling hole 124a of the corresponding side wall 124.

Referring to FIGS. 14 to 18 , a third embodiment of the connector assembly 100 of the present invention is different from the first embodiment in that the pressure spring 43 integrally constructed on the moving plate 41 includes a plurality of leaf spring portions 431″ constructed on both sides of the moving plate 41 and arranged front and rear, and the leaf spring portions 431″ of the pressure spring 43 extend forward and downward. The heat sink 42 is constructed with the pressure spring action structure 44, and the pressure spring action structure 44 includes a plurality of interference slopes 442 constructed on both sides of the heat sink 42 and extending obliquely rearward and upward, and the interference slopes 442 correspond to the leaf spring portions 431″, respectively. In the third embodiment, the moving plate 41 is basically translated backward from the first position to the second position.

As shown in Figures 15 and 16, when the moving plate 41 is located at the first position, the radiator 42 is located at the release position due to the elastic force provided by the supporting spring 46, and the interference slope 442 of the pressure spring action structure 44 constructed on the radiator 42 is respectively located behind the plate spring part 431'' of the pressure spring 43 constructed on the moving plate 41. As shown in FIGS. 17 and 18 , when the moving plate 41 is pushed by the pluggable module 3 (see FIG. 1 ) and moves backward from the first position to the second position, the plate spring portion 431'' of the pressure spring 43 constructed on the moving plate 41 acts downward on the interference slope 442 of the pressure spring acting structure 44 constructed on the heat sink 42, thereby linking the heat sink 42 to move downward from the release position to the contact position. When the pluggable module 3 is withdrawn from the plug-in channel 11a, the interference slope 442 of the inclined pressure spring action structure 44 constructed on the heat sink 42 will act forward on the plate spring portion 431'' of the inclined pressure spring 43 constructed on the moving plate 41, so that the moving plate 41 is moved back to the first position through the action between the pressure spring action structure 44 and the pressure spring 43.

In addition, in the third embodiment, the two supporting spring structures 461 of the supporting spring 46 are in the form of independent components and are assembled to the heat sink frame 12 by, for example, welding or buckling.

19 to 23 , a fourth embodiment of the connector assembly 100 of the present invention differs from the third embodiment in that the heat sink module 4 further includes a moving plate guide structure 47, and the moving plate 41 can be guided by the moving plate guide structure 47 to move between the first position at the front and top and the second position at the rear and bottom relative to the heat sink frame 12. The moving plate guide structure 47 includes a plurality of guide members 471 and a plurality of guide grooves 472 that cooperate with each other. The guide grooves 472 are constructed on the side wall 124 of the radiator frame 12 and extend obliquely rearward and downward. The guide members 471 are constructed on the side of the moving plate 41 in an assembly manner such as by riveting and are respectively assembled into the guide grooves 472. The moving plate 41 can move along the guide grooves 472 along with the guide members 471.

In addition, in the fourth embodiment, the plurality of plate spring portions 431''' of the pressure spring 43 integrally constructed on the moving plate 41 are used to directly act on both sides of the heat sink 42.

As shown in Figures 20 and 21, when the moving plate 41 is located at the first position, the force of the plate spring portion 431''' of the pressure spring 43 constructed on the moving plate 41 acting downward on the radiator 42 is smaller than the force of the two support spring structures 461 of the support spring 46 acting upward on the radiator 42, so the radiator 42 is located at the upper release position. It should be noted that, when the movable plate 41 is located at the first position, although the leaf spring portion 431''' of the pressure spring 43 constructed on the movable plate 41 still contacts and acts on the radiator 42, in other embodiments, the leaf spring portion 431''' of the pressure spring 43 constructed on the movable plate 41 may not contact and act on the radiator 42, and is not limited to the fourth embodiment.

As shown in FIGS. 22 and 23 , when the moving plate 41 is pushed by the pluggable module 3 (see FIG. 1 ) and moves backward from the first position to the second position, the moving plate 41 moves downward in addition to backward by the action of the moving plate guide structure 47 , so the plate spring portion 431''' of the pressure spring 43 on the moving plate 41 is The plate spring portion 431''' of the pressure spring 43 constructed on the moving plate 41 directly acts downward on the radiator 42, and the force acting downward on the radiator 42 is greater than the force acting upward on the radiator 42 by the two supporting spring structures 461 of the supporting spring 46, thereby linking the radiator 42 to move downward from the release position to the contact position.

When the pluggable module 3 is withdrawn from the plug-in channel 11a, the supporting spring 46 acts upward on the heat sink 42 to move the heat sink 42 to the release position. The heat sink 42 acts upward on the plate spring portion 431''' of the pressure spring 43 of the moving plate 41. Therefore, the action of the heat sink 42 and the pressure spring 43 causes the moving plate 41 to move back to the first position which is relatively upward and forward.

Referring to FIGS. 24 to 28 , the fifth embodiment of the connector assembly 100 of the present invention is different from the fourth embodiment in that the supporting spring 46 is constructed on the moving plate 41, and the supporting spring 46 includes a plurality of supporting brackets 462 constructed on both sides of the moving plate 41, and a plurality of elastic supporting brackets 463 constructed on both sides of the moving plate 41 and elastically supporting downward against the lower wall 122 of the heat sink frame 12. Each of the supporting brackets 462 has a supporting hook 462a extending downward and inward and used to hook the side of the heat sink 42. The supporting portions extend downward and obliquely forward and backward respectively, wherein the elastic supporting portion 463 at the front extends obliquely forward, and the elastic supporting portion 463 at the rear extends obliquely backward. The elastic force provided by the elastic supporting portions 463 of the supporting spring 46 causes the supporting hooks 462a of the supporting support portions 462 of the supporting spring 46 to face upward and elastically support the radiator 42.

As shown in FIGS. 25 and 26 , when the movable plate 41 is located at the first position located at the upper and front side, the support hooks 462 a of the support brackets 462 of the support spring 46 support the heat sink 42 at the upper release position.

As shown in FIG. 27 and FIG. 28 , when the moving plate 41 is pushed by the pluggable module 3 (see FIG. 1 ) and moves backward from the first position to the second position, the moving plate 41 moves backward and downward. Since the positions of the supporting hooks 462a of the supporting brackets 462 of the moving plate 41 and the supporting spring 46 move downward, the heat sink 42 is linked to move downward from the release position to the contact position. In addition, at this time, the elastic force of the pressure spring 43 causes the thermal coupling portion 421b at the bottom of the heat sink 42 to contact the surface of the pluggable module 3 downward and with pressure. In this state, the elastic supporting portions 463 of the supporting spring 46 are compressed and provide an upward elastic force for driving the moving plate 41 to return to the first position and linking the heat sink 42 to return to the release position.

When the pluggable module 3 is withdrawn from the plug-in channel 11a, the elastic supporting portions 463 of the supporting spring 46 recover from compression, and drive the moving plate 41 to move upward and forward to recover to the first position and link the heat sink 42 to recover upward to the release position.

Referring to FIG. 29 , a sixth embodiment of the connector assembly 100 of the present invention differs from the fourth embodiment in that the two supporting spring structures 461 of the supporting spring 46 are integrally constructed on the lower wall 122 of the radiator frame 12 and supported upward on the left and right sides of the radiator 42.

Referring to Figures 30 to 32, the seventh embodiment of the present invention shows a double-layer structured connector assembly 100. The seventh embodiment differs from the second embodiment in that the connector assembly 100 further comprises a built-in heat sink frame 12' disposed in the shell 11 of the cage 1, and a built-in heat sink module 4' disposed in the built-in heat sink frame 12'. The shell 11 has two plug-in channels 11a, which are located at the top and bottom and connected to each other at the rear section, and two front-end sockets 11b, which are located at the front and connected to the two plug-in channels 11a and are for the pluggable module 3 to be inserted. The heat sink frame 12 and the built-in heat sink frame 12' are respectively located above the two plug-in channels 11a.

The structure of the built-in heat sink frame 12' is substantially the same as that of the heat sink frame 12. The built-in heat sink frame 12' has an upper wall 121' and a lower wall 122' that are spaced opposite to each other, a front connecting wall 123' connecting the front ends of the upper wall 121' and the lower wall 122', two side walls 124' connecting the left and right sides of the upper wall 121' and the lower wall 122' and spaced opposite to each other, and a plurality of fixing flaps 129 formed on the side edges of the upper wall 121' and the lower wall 122'. Each of the side walls 113 of the housing 11 also has a plurality of fixing through holes 113a that correspond to and cooperate with the built-in heat sink frames 12'. The built-in heat sink frames 12' pass through the fixing through holes 113a and are then bent so that the built-in heat sink frames 12' are assembled to the two side walls 113 of the housing 11.

The built-in heat sink frame 12' also has a built-in heat sink accommodating space 126' which is defined by the upper wall 121', the lower wall 122', the front connecting wall 123' and the two side walls 124' and accommodates the built-in heat sink module 4', and a lower opening 127' formed on the lower wall 122' to connect the built-in heat sink accommodating space 126' to the plug-in channel 11a below. The composition and actuation of the built-in heat sink module 4' are substantially the same as those of the heat sink module 4. The built-in heat sink module 4' also includes a moving plate 41', a heat sink 42', a pressure spring 43', a pressure spring action structure 44', two return springs 45', and a support spring 46', and therefore will not be described in detail here.

Referring to FIG. 33 and FIG. 34 , the eighth embodiment of the connector assembly 100 of the present invention is different from the seventh embodiment in that the connector assembly 100 further includes two side heat sinks 5, which are disposed on the left and right sides of the heat sink 42' of the built-in heat sink module 4' through the side openings 113b formed on the two side walls 113 of the housing 11 to enhance the heat dissipation performance of the heat sink 42' of the built-in heat sink module 4'. For example, the side heat sinks 5 can be locked to the left and right sides of the heat sink 42' of the built-in heat sink module 4' by a plurality of fixing members 6. In addition, in the eighth embodiment, a thermally conductive gasket 7 is provided between the side heat sink 5 and the heat sink 42' of the built-in heat sink module 4' to ensure thermal conductivity between the side heat sink 5 and the heat sink 42' of the built-in heat sink module 4'.

In summary, the present invention links the pressure spring 43 to actuate the heat sink 42 to move to the contact position of the pluggable module 3 by the backward movement of the moving plate 41, so that the heat sink 42 can be moved to the position of contacting the surface of the pluggable module 3 only after the pluggable module 3 is inserted into the plug-in channel 11a of the cage 1, so as to reduce the friction between the bottom of the heat sink 42 and the pluggable module 3 during the insertion process of the pluggable module 3, prevent the wear problem of the bottom of the heat sink 42, or prevent the thermal pad 421d (thermal interface material) provided at the bottom of the heat sink 42 from being scratched. Furthermore, the elastic force of the pressure spring 43 makes the bottom of the heat sink 42 face downward and contact the surface of the pluggable module 3 with pressure, which can improve the heat conduction efficiency and increase the heat dissipation effect. On the other hand, the moving plate 41 is a thin plate structure and the pressure spring 43 is located between the moving plate 41 and the heat sink 42, so that the entire heat sink assembly has a low profile structure effect. Furthermore, the plurality of plate spring parts 431 of the pressure spring 43 between the moving plate 41 and the heat sink 42 are respectively arranged on both sides and arranged front and back, which can make the movement of the heat sink 42 more balanced and stable.

However, the above is only an example of the implementation of the present invention, and it should not be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
