Description

Connector Assemblies

The present invention relates to a connector assembly, in particular to a connector assembly with a movable heat sink.

Chinese invention patent publication number CN110296628A (corresponding to US invention patent publication number US10,651,598 B2) discloses a heat exchange structure, which includes a metal part, a lever, and a frame, wherein 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 causes the lever to rotate, and the lever applies a downward force to the rear end of the metal part, and the front end of the metal part pushes the front edge of the frame downward, so that the frame drives the heat sink and the thermal pad disposed thereon to contact the heat source. However, in the prior art, an additional frame is required to install the lever and the metal part, and the structure is relatively complicated. Moreover, the metal part needs to be installed at the top of the radiator, which requires a groove to be dug at the top of the radiator to install the metal part. The metal part occupies the space required for elastic deformation in the up-down direction, and the lever occupies the space required for rotation and swinging in the up-down direction and the forward-backward direction. Therefore, it not only occupies a lot of space in the radiator, but also reduces the heat dissipation area of the radiator, thereby greatly reducing the heat dissipation efficiency and making it difficult to reduce the thickness of the radiator and the overall heat dissipation module. In addition, the metal part is only connected to the radiator at a single point (screw), and the lever is pressed on the rear end of the metal part when pushed. This design makes the radiator easy to tilt.

U.S. Patent Publication No. US10222844 B1 discloses a sliding ramp with an inclined surface disposed on the top side of a cage, and a leaf spring disposed on the back side of the cage. The heat sink moves along the inclined sliding ramp through a guide pin, so that the heat sink is pressed downward against the replaceable electronic module to establish thermal contact. When the leaf spring is released, the heat sink is pushed toward the front end of the sliding ramp, thereby pushing the replaceable electronic module out of the cage. Since the heat sink disclosed in this prior art moves obliquely along the inclined sliding ramp through a guide pin, it is necessary to reduce the size of the protrusion on the bottom surface of the heat sink to be smaller than the window size of the cage top wall to avoid interference. Furthermore, since the compressible amount of the thermal interface material provided on the convex portion of the bottom surface of the heat sink is limited, the heat sink basically directly and rigidly contacts the surface of the replaceable electronic module according to the tilt angle and length of the sliding ramp. Too much interference between the two may hinder the insertion of the replaceable electronic module and even damage the thermal interface material. Too little interference may affect the contact area and heat dissipation performance of the thermal interface material.

Therefore, an object of the present invention is to provide a connector assembly that can improve at least one problem in the prior art.

Therefore, in some embodiments of the connector assembly of the present invention, it includes a guide shield, a clip, a heat sink, and a support spring. The guide shield has a top wall and an insertion channel located inside, and the top wall has a window connected to the insertion channel. The clip is assembled on the guide shield and can move forward and backward between a first position in front and a second position in rear relative to the guide shield. The clip has a force spring and a push portion extending into the insertion channel through the window, and the force spring has a force portion. The heat sink is assembled on the clip and limited by the clip and the guide shield, and can move up and down between a third position at the top and a fourth position at the bottom relative to the guide shield. The heat sink has a thermal coupling portion located at the bottom and a force spring action protrusion located at the side. The force application portion of the force spring is at the side of the heat sink and acts on the force spring action protrusion. The support spring elastically supports the heat sink upward. The force application portion of the force spring of the clip interacts with and guides the force spring action protrusion and the elastic force of the support spring on the heat sink, so that the forward and backward movement of the clip between the first position and the second position links the up and down movement of the heat sink between the third position and the fourth position.

In some implementations, the force applying portion of the force applying spring extends obliquely backward and upward, and the force applying portion is located in front of the force applying spring action protrusion. The force applying portion is used to act downward and backward on the force applying spring action protrusion and guide the force applying spring action protrusion to move.

In some embodiments, the buckle also has a base plate connected to the force applying spring, and the force applying spring includes a forearm, a rear arm, a first arm and a second arm, the lower end of the forearm and the lower end of the rear arm are connected to the base plate of the buckle, the first arm extends obliquely backward and downward from the upper end of the forearm, the second arm extends obliquely backward and upward from the end of the first arm and is connected to the upper end of the rear arm, and the lower contour of the second arm constitutes the force applying portion.

In some embodiments, one of the front arm and the rear arm is integrally connected to the base plate, and the other is connected to the base plate by welding.

In some embodiments, the clip further has a base plate connected to the force spring, and the support spring is located below the heat sink and is integrally connected to the base plate of the clip.

In some implementations, the buckle further has a limit frame located on the outer side of the force spring, and the force spring action protrusion is located behind the force applying portion of the force spring and extends into the limit frame.

In some embodiments, the guide shield has a guide groove, the buckle has a guide block that can be assembled with the guide groove movably forward and backward, and the guide block is restricted from moving up and down by the guide groove.

In some implementations, the clip further comprises a base plate connected to the force applying spring, the base plate comprising a frame opening and side limit frames extending upward from both sides of the frame opening, the length of the frame opening in the front-to-rear direction is greater than the length of the window of the guide shielding cover in the front-to-rear direction, the thermal coupling portion of the heat sink is used to pass through the frame opening and the window and extend into the plug-in channel, the guide shielding cover further comprises a front limit frame and a rear limit frame extending upward from the front and rear ends of the window, the front limit frame and the rear limit frame are passed through the frame opening of the clip, and together with the side limit frames of the clip, limit the position of the thermal coupling portion of the heat sink in the front-to-rear and left-to-right directions and upward, the tops of the side limit frames, the front limit frame and the rear limit frame are higher than the base plate of the clip by a predetermined height and higher than the bottom of the support spring.

In some embodiments, the clip further comprises a plurality of support frames extending upward from the base plate, wherein the top of the support frames is higher than the base plate of the clip by a predetermined height and higher than the bottom of the support spring.

In some embodiments, the thermal coupling portion of the heat sink includes a thermal pad.

In some embodiments, the connector assembly is suitable for plugging with a pluggable module. When the pluggable module is inserted into the plugging channel of the guide shield from front to back, an external force is provided to push the pushed portion of the buckle, so that the buckle gradually moves from the first position to the second position, causing the force spring to elastically deform and the elastic force of the force-applying portion of the force spring to gradually act on the force-applying spring action protrusion. After the downward force applied by the force spring to the heat sink is greater than the upward supporting force of the support spring and the support spring is compressed downward, the force-applying spring action protrusion is guided along the force-applying portion. The heat sink moves downward from the third position to the fourth position, and the thermal coupling portion of the heat sink contacts the surface of the pluggable module with contact pressure through the window; when the pluggable module withdraws from the plug-in channel, the external force on the clip is released, the supporting spring recovers from the pressure and lifts the heat sink upward, so that the heat sink moves upward from the fourth position to the third position, and the acting protrusion of the force-applying spring of the heat sink moves upward along the force-applying portion under guidance, and acts on the force-applying portion of the force-applying spring upward and forward, so that the clip moves from the second position to the first position.

The present invention uses the mutual action and guidance of the force spring of the clip on the force spring action protrusion and the elastic force of the support spring on the heat sink, so that the forward and backward movement of the clip at the first position links the up and down movement of the heat sink between the third position and the fourth position. Therefore, the heat sink can be moved to the fourth position in contact with the pluggable module only after the pluggable module is inserted, thereby reducing the friction between the pluggable module and the heat sink during the insertion process and preventing the thermal pad provided on the heat sink from being scratched. At the same time, the force spring of the clip allows the heat sink to contact the surface of the pluggable module with elastic pressure to improve the heat conduction efficiency and increase the heat dissipation effect. In addition, the heat sink is restricted to move vertically between the third position and the fourth position, so the front-to-back dimension of the thermal coupling portion at the bottom of the heat sink can be expanded as much as possible to match the front-to-back dimension of the window of the top wall (and the frame opening of the clip). Furthermore, since the force spring is arranged on the side of the heat sink, the clip will not cross the heat sink horizontally and will not occupy the space inside the heat sink, so that the heat sink can have a larger heat dissipation area and higher heat dissipation efficiency.

Referring to Fig. 1 to Fig. 4, an embodiment of the connector assembly 100 of the present invention is suitable for plugging with a pluggable module 200. The pluggable module 200 has a housing 201, a plug-in circuit board 202 and a cable 203. The housing 201 has a plug-in portion 201a, the plug-in circuit board 202 is protrudingly disposed at the front end of the plug-in portion 201a, and the cable 203 is disposed at the rear end of the housing 201 and electrically connected to the plug-in circuit board 202. The connector assembly 100 includes a guide shield 1, a socket connector 2, a buckle 3, a heat sink 4, and a plurality of support springs 5.

The guide shield 1 is, for example, made of a metal sheet by die stamping and bending. The guide shield 1 is used to be set on a circuit board (not shown) and extends along a front-rear direction D1 (the arrow direction is the front, and the reverse direction is the rear). The guide shield 1 includes a cover body 11 and a plurality of grounding members 12 assembled on the cover body 11. The cover body 11 has a top wall 111, a bottom wall 112 spaced from the top wall 111 along a vertical direction D2 (the arrow direction is the top, and the reverse direction is the bottom), and a left-right direction D3. Two side walls 113 are spaced apart and connected between the top wall 111 and the bottom wall 112 (arrow direction is right, reverse direction is left), a rear wall 114 is connected to the top wall 111 and the rear edges of the two side walls 113, a plug-in channel 115 is defined by the top wall 111, the bottom wall 112, the two side walls 113 and the rear wall 114, a plurality of pins 116 extending downward from the side walls 113 and suitable for being fixed on the circuit board and/or connected to a grounding track (not shown), and a plurality of guide pieces 117 extending upward from the two side walls 113 and each forming a guide groove 117a extending along the front-rear direction D1. The insertion channel 115 has a forward insertion opening 115 a and a bottom opening 115 b (see FIG. 7 ) located at the rear of the bottom and defined by the bottom wall 112 , the side wall 113 , and the rear wall 114 of the cover body 11 and facing downward.

The top wall 111 of the cover body 11 has a window 111a connected to the insertion channel 115, a guide portion 111b extending downward from the rear section of one side of the window 111a into the insertion channel 115, a stop portion 111c extending downward from the rear end of the window 111a into the insertion channel 115, a front limit frame 111d extending upward from the front end of the window 111a, and a rear limit frame 111e extending upward from the rear end of the window 111a. Each of the side walls 113 of the cover body 11 has an opening 113a corresponding to the insertion channel 115, and an inwardly extending elastic sheet 113b extending obliquely from the front edge of the opening 113a toward the inside of the cover body 11 and backward.

In this embodiment, the guide shielding cover 1 of the connector assembly 100 can be set in a mounting hole (not shown) of a casing (not shown), and each grounding piece 12 has a plurality of elastic fingers 121 extending backward from the front end of the cover body 11 and distributed on the outer side and the inner side of the cover body 11. The elastic fingers 121 located on the outer side of the cover body 11 are used to contact the edge of the mounting hole of the casing, and the elastic fingers 121 located on the inner side of the cover body 11 are used to contact the pluggable module 200.

The socket connector 2 is used to be arranged on the circuit board and is accommodated in the rear section of the plug-in channel 115 of the guide shielding cover 1 through the bottom opening 113a. The socket connector 2 has an insulating shell 21 and a plurality of terminals 22 arranged on the shell 21. The shell 21 has a docking slot 211 facing forward and for inserting the plug-in circuit board 202 of the pluggable module 200. Each terminal 22 has a contact portion 221 located in the docking slot 211 and a tail portion 222 extending downward from the bottom of the shell 21 (see FIG. 10). The tail portions 222 of the terminals 22 are respectively used to be soldered to the solder pads on the circuit board to connect to the conductive traces on the circuit board.

The plug-in portion 201a of the pluggable module 200 has two locking grooves 201b located at the left and right sides and used to correspond to the inwardly extending elastic sheets 113b of the two side walls 113 of the cover body 11, a guide groove structure 201c located at the top of the front end and used to correspond to the guide portion 111b of the top wall 111 of the cover body 11, and a positioning structure 201d located at the top and used to correspond to the stopper portion 111c of the top wall 111 of the cover body 11. The inwardly extending elastic sheets 113b of the two side walls 113 of the cover body 11 are used to cooperate with the locking grooves 201b of the pluggable module 200 inserted into the plug-in channel 115 to produce a locking effect. The guide portion 111b is used to be inserted into the guide groove structure 201c of the pluggable module 200 to produce a guiding effect. The stop portion 111c is used to be stopped at the alignment structure 201d of the pluggable module 200 to limit the insertion position of the pluggable module 200. The pluggable module 200 also has an unlocking member 204, which can push the inner extension spring sheet 113b out of the buckle groove 201b when being pulled.

The buckle 3 is assembled on the guide shielding cover 1 and is restricted to move forward and backward. The buckle 3 has a bottom plate 31 assembled on the top wall 111 of the guide shielding cover 1, four force springs 32 connected to the bottom plate 31 and distributed on the left and right sides of the bottom plate 31, and four limit frames 33 respectively located on the outer sides of the four force springs 32 and each having an upper frame strip 331. The bottom plate 31 has a plurality of guide blocks 311 protruding from the left and right side edges and movably assembled in the guide grooves 117a of the guide pieces 117 along the front-rear direction D1, a frame opening 312 located above the window 111a, side limit frames 313 extending upward from the left and right sides of the frame opening 312, a plurality of support frames 34 extending upward from the bottom plate 31, and a push receiving portion 314 extending downward from the rear end of the frame opening 312 and extending into the insertion channel 115 through the window 111a. The support frames 34 and the side limit frames 313 have the function of strengthening the structural strength of the buckle 3.

The guide blocks 311 are restricted in movement in the up-down direction D2 by the guide grooves 117a of the guide sheets 117, while the base plate 31 is restricted in movement in the left-right direction D3 by the guide sheets 117. By enabling the guide blocks 311 to cooperate with the guide grooves 117a of the guide sheets 117 so as to be movable forward and backward, the fastener 3 can basically be restricted in movement only in the front-back direction D1, so that the fastener 3 can only move between a first position in the front (see FIG. 5) and a second position in the rear (see FIG. 8) along the front-back direction D1 relative to the guide shielding cover 1. In the first position, the guide blocks 311 are against the front ends of the guide grooves 117a of the guide sheets 117; in the second position, the guide blocks 311 are against the rear ends of the guide grooves 117a of the guide sheets 117. In addition, the length of the frame opening 312 of the bottom plate 31 of the clip 3 in the front-to-back direction D1 is greater than the length of the window 111a of the guide shielding cover 1 in the front-to-back direction D1, and the width of the frame opening 312 in the left-right direction D3 is roughly corresponding to the width of the window 111a in the left-to-right direction D3. Therefore, when the clip 3 moves between the first position and the second position relative to the cover body 11 of the guide shielding cover 1 along the front-to-back direction D1, the bottom plate 31 of the clip 3 does not cover the window 111a of the guide shielding cover 1. Furthermore, the front limit frame 111d and the rear limit frame 111e of the cover body 11 of the guide shielding cover 1 are upwardly penetrated through the frame opening 312 of the buckle 3, and the front limit frame 111d and the rear limit frame 111e can also help limit the movement of the buckle 3 between the first position and the second position in the front-back direction D1. Specifically, the rear limit frame 111e can limit the frame opening 312 of the bottom plate 31 at the first position, and the front limit frame 111d can limit the frame opening 312 of the bottom plate 31 at the second position. The side limit frames 313 and the supporting frames 34 of the buckle 3 and the tops of the front limit frame 111d and the rear limit frame 111e of the guide shielding cover 1 are all higher than the bottom plate 31 of the buckle 3 by a predetermined height.

The force springs 32 extend on the surface formed by the front-rear direction D1 and the up-down direction D2. Each of the force springs 32 integrally includes a front arm 321, a rear arm 322, a first arm 323 and a second arm 324. The first arm 323 extends obliquely backward and downward from the upper end of the front arm 321, and the second arm 324 extends obliquely backward and upward from the end of the first arm 323 and is connected to the upper end of the rear arm 322. The front arm 321, the rear arm 322, the first arm 323 and the second arm 324 generally form an M-shaped frame structure. Among them, the surface (lower contour) facing downward and backward in the front section of the second arm 324 forms a force application portion 324a extending obliquely backward and upward. One of the front arm 321 and the rear arm 322 is integrally connected to the bottom plate 31, and the other is connected to the bottom plate 31 by welding. In this embodiment, the lower end of the front arm 321 of the force spring 32 located at the front is integrally connected to the bottom plate 31 of the buckle 3, and the lower end of the rear arm 322 is connected to the bottom plate 31 of the buckle 3 by welding. The lower end of the front arm 321 of the force spring 32 located at the rear is connected to the bottom plate 31 of the buckle 3 by welding, and the lower end of the rear arm 322 is integrally connected to the bottom plate 31 of the buckle 3. However, in other variations of implementation, the connection method between the force applying spring 32 located at the front and the force applying spring 32 located at the rear and the bottom plate 31 can be adjusted according to needs.

1 to 4, the heat sink 4 is assembled on the clip 3, and the force applying portion 324a of the force applying spring 32 of the clip 3 is located at the side of the heat sink 4. The heat sink 4 is limited by the clip 3 and the cover body 11 of the guide shielding cover 1 and is restricted to move only up and down. The heat sink 4 has a base plate 41, a plurality of heat sink fins 42 extending along the front-rear direction D1 and arranged in parallel and integrally formed from the top surface of the base plate 41 upward in the left-right direction D3, and four force spring action protrusions 43 located at the side and protruding outward from the two side edges of the base plate 41 along the left-right direction D3, the force spring action protrusions 43 respectively corresponding to the force application parts 324a of the force application springs 32 of the buckle 3 and respectively used to be acted on and guided by the force application parts 324a of the force application springs 32. It should be noted that in a modified embodiment, the heat sink fins 42 can also be mutually buckled and set on the top surface of the base plate 41 in a manner such as welding.

The base plate 41 has a thermal coupling portion 411 formed downward, and the thermal coupling portion 411 is used to pass through the frame opening 312 and the window 111a and extend into the plug-in channel 115 to contact the pluggable module 200 inserted into the plug-in channel 115, thereby enhancing the heat dissipation of the heat sink 4. The left and right side limit frames 313 of the clip 3 and the front limit frame 111d and the rear limit frame 111e of the guide shield 1 together limit the position of the thermal coupling portion 411 of the heat sink 4 in the front-back direction D1 and the left-right direction D3, so that the heat sink 4 can basically be limited to move only in the up-down direction D2, and the heat sink 4 can only move between a third position located at the top (see FIG. 7) and a fourth position located at the bottom (see FIG. 10). In this embodiment, the thermal coupling portion 411 includes a thermally conductive pad 411a located at the bottom and used to contact the pluggable module 200. The thermally conductive pad 411a can be, for example, a thermal interface material (Thermal Interface Material). The thermal interface material can be selected from a combination of materials having properties such as high thermal conductivity, high flexibility, compressibility, insulation, and wear resistance, or can be selected from a combination of a base material and a phase change material (phase change material), for example.

The force spring acting protrusions 43 are located behind the force applying portions 324a of the force applying springs 32 and extend into the limiting frames 33. The force spring acting protrusions 43 are limited in the upward direction by the upper frame bars 331 of the limiting frames 33, so as to limit the maximum height of the heat sink 4 in the third position through the limiting frames 33. The force applying portions 324a of the force applying springs 32 located in front of the force spring acting protrusions 43 can act on the force spring acting protrusions 43 downward and backward, and guide the force spring acting protrusions 43 to move.

In this embodiment, four supporting springs 5 are located below the base plate 41 of the heat sink 4 and are integrally connected to the bottom plate 31 of the clip 3. It should be noted that the four supporting springs 5 may also be independent components in other embodiments and assembled on the clip 3 by welding or buckling. Two supporting springs 5 are arranged front and back on each side of the bottom plate 31. The supporting spring 5 located at the front of each side extends forward and upward in an inclined manner, and the supporting spring 5 located at the rear extends backward and upward in an inclined manner. The four supporting springs 5 elastically support the base plate 41 of the heat sink 4 upward together. The tops of the aforementioned side limit frame 313, the supporting frames 34, the front limit frame 111d and the rear limit frame 111e are higher than the bottoms of the supporting springs 5 (the connection between the supporting springs 5 and the bottom plate 31 of the buckle 3), and the side limit frame 313, the supporting frames 34, the front limit frame 111d and the rear limit frame 111e can It is sufficient to limit the lowest downward position of the radiator 4. For example, when the radiator 31 is assembled, it may be pressed down by a fixture. At this time, the side limit frame 313, the support frames 34, the front limit frame 111d and the rear limit frame 111e can help support the radiator 31, thereby preventing the support springs 5 from being excessively pressed down by the radiator 4 and deformed.

Referring to FIGS. 5 to 7 , when the pluggable module 200 has not yet been inserted into the plug-in channel 115, the clip 3 is in the first position, and the heat sink 4 is supported by the supporting springs 5 and is in the third position. At this time, the thermal coupling portion 411 of the heat sink 4 does not extend into the plug-in channel 115. It should be noted that in other embodiments, when the heat sink 4 is in the third position, the thermal coupling portion 411 of the heat sink 4 may extend into the plug-in channel 115 but be located at a height that does not contact the upper surface of the pluggable module 200, so that before the pluggable module 200 pushes the pushed portion 314, there is a gap between the thermal coupling portion 411 at the bottom of the heat sink 4 and the upper surface of the pluggable module 200.

8 to 10 , when the pluggable module 200 is inserted from the socket 115a into the insertion channel 115 of the guide shielding cover 1 from the front to the back, the pluggable module 200 provides an external force to push the pushed portion 314 of the fastener 3, so that the fastener 3 gradually moves backward from the first position to the second position. During this process, the force springs 32 produce elastic deformation, and the force portions 324a of the force springs 32 gradually act downward and backward elastically on the force spring action protrusions 43. After the downward force applied by the force portions 324a of the force springs 32 to the force spring action protrusions 43 is greater than the upward supporting force of the support springs 5 and compresses the support springs 5, the force spring action protrusions 43 are guided to move along the obliquely extended force portions 324a of the force springs 32, so that the radiator 4 gradually moves downward from the third position to the fourth position. In the fourth position, the thermal coupling portion 411 of the heat sink 4 extends into the plug-in channel 115 through the window 111 a and the frame opening 312 and contacts the surface of the pluggable module 200 with contact pressure.

Referring to Figures 5 to 7, when the pluggable module 200 is withdrawn from the plug-in channel 115, the external force on the buckle 3 is released, the supporting springs 5 recover from the pressure and lift the heat sink 4 upward, so that the heat sink 4 moves upward from the fourth position to the third position. At this time, the force spring action protrusions 43 are guided to move along the inclined extending force application parts 324a of the force application springs 32, and the force spring action protrusions 43 move upward and act and push the force application parts 324a of the force application springs 32 upward and forward, so that the buckle 3 moves from the second position to the first position.

In summary, the present invention uses the interaction and guidance of the force spring 32 of the clip 3 on the force spring action protrusion 43, and the elastic force of the support spring 5 on the heat sink 4, so that the forward and backward movement of the clip 3 in the first position links the up and down movement of the heat sink 4 between the third position and the fourth position, so that the heat sink 4 can be moved only after the pluggable module 200 is inserted. Move to the fourth position contacting the pluggable module 200, reduce the friction between the pluggable module 200 and the heat sink 4 during the insertion process, prevent the thermal pad 411a provided on the heat sink 4 from being scratched, and at the same time, the heat sink 4 is in contact with the surface of the pluggable module 200 with elastic pressure through the force spring 32 of the clip 3, so as to improve the heat conduction efficiency and increase the heat dissipation effect. In addition, the heat sink 4 is restricted to move up and down between the third position and the fourth position, so the front-to-back size of the thermal coupling part 411 at the bottom of the heat sink 4 can be expanded as much as possible in the front-to-back size in accordance with the window 111a of the top wall 111 (and the frame opening 312 of the clip 3). Furthermore, since the force spring 32 is disposed on the side of the heat sink 4, the clip 3 will not cross the heat sink 4 horizontally and will not occupy the space inside the heat sink 4, so that the heat sink 4 can have a larger heat dissipation area and higher heat dissipation efficiency.
