Before the present invention is described in detail, it should be noted that similar components are represented by the same reference numerals in the following description.

Refer to Figures 1 to 6, which are a first embodiment of the connection device of the present invention. The connection device is suitable for electrical connection of multiple pluggable components (not shown), and includes a circuit board 100, a connector assembly 200, a liquid cooling plate 300, a frame 400 and a plurality of screws. For the convenience of explanation, the directional terms of the connection device are defined according to the use environment of the connection device, that is, an arrow in a front-to-back direction X in Figure 1 points to the rear side of the connection device, and the reverse direction is the front side; an arrow in a left-right direction Y in Figure 1 points to the left side of the connection device, and the reverse direction is the right side; an arrow in an up-down direction Z in Figure 1 points to the upper side of the connection device, and the reverse direction is the lower side. In addition, to simplify the description, the screws are exemplified as screws 500a, 500b, and 500c according to different connection relationships.

Referring to FIG. 1 and FIG. 2 , the circuit board 100 is provided with a circuit pattern not shown in the figure, and the connector assembly 200 is arranged thereon. The connector assembly 200 includes a metal shell 1 having a plurality of plug-in channels 13 provided therein, and a plurality of electrical connectors 10 (see FIG. 2 ) respectively arranged at the rear ends of the plug-in channels 13. Each of the electrical connectors 10 has a docking slot 10a for the plug-in assembly to be plugged in for electrical connection. The opening of each of the plug-in channels 13 faces forward and extends along the front-to-rear direction X so that the plug-in assembly can be inserted from front to rear. In the present embodiment, the number of the plug-in channels 13 is four, and the plug-in channels 13 are arranged along the left-right direction Y, but the number of the plug-in channels 13 can also be one, two, three or more than five, and is not limited to a specific number.

Referring to FIGS. 1 to 5 , the metal housing 1 is, for example, made of a metal sheet by die stamping and bending, and can be used for electromagnetic shielding. The metal housing 1 is in the form of a rectangular parallelepiped but not limited thereto, and has two side walls 11 located on the left and right sides, respectively, and a rear wall 12 connected to the rear sides of the side walls 11 on the left and right sides, respectively. Each of the side walls 11 has a side wall body 111, a plurality of protrusions 112 protruding outwardly (i.e., away from the side wall body 111) from the outer surface of the side wall body 111 in the left-right direction Y, and a side retaining portion 113. Each of the side holding portions 113 has a first guide surface 113a (see FIG. 5 ) extending outward and backward from the outer surface of the side wall body 111. In this embodiment, the number of the protrusions 112 is two, but depending on the usage, the number of the protrusions 112 may be only one or more than three. In addition, the side holding portion 113 and the two protrusions 112 are arranged along the front-rear direction X, but the arrangement may also be changed depending on the usage.

The liquid cooling plate 300 is located above the connector assembly 200 and has cooling liquid flowing inside thereof, and is used for thermal connection with the pluggable assembly plugged into the plugging channel 13 to reduce the temperature of the pluggable assembly. The frame 400 includes two side frames 2 spaced apart on the left and right, a front frame 3 connected to the front side of the side frames 2 on the left and right sides, and a rear frame 4 connected to the rear side of the side frames 2 on the left and right sides. The front frame 3, the rear frame 4 and the two side frames 2 jointly define a receiving space 5, and the receiving space 5 is for the liquid cooling plate 300 to be placed, so that the front frame 3, the rear frame 4 and the two side frames 2 surround the liquid cooling plate together. Preferably, the two side frames 2 are screwed to the left and right sides of the liquid cooling plate 300 using the screws 500a, and the front frame 3 is screwed to the front side of the liquid cooling plate 300 using the screws 500b, and the rear frame 4 is screwed to the rear side of the liquid cooling plate 300 using the screws 500c, so that the frame 400 can be stably combined with the liquid cooling plate 300.

Each of the side frames 2 has a side frame body 21, a side fastener 22 extending downward from the bottom edge of the side frame body 21, and a plurality of first stoppers 23. The side fastener 22 can be elastically deformed under force. Each of the side fasteners 22 has a first buckle hole 221a that penetrates the left and right sides and can allow the side retaining portion 113 to penetrate. When the side retaining portions 113 are respectively inserted into the first buckle holes 221a, the side fasteners 22 are respectively restricted by the side retaining portions 113 to move up, down, forward, and backward, that is, the side fasteners 22 are respectively buckled on the side retaining portions 113, so that the liquid cooling plate 300 is assembled to the connector assembly 200 through the frame 400, and is combined with the connector assembly 200 and stacked up and down, and the relative displacement of the liquid cooling plate 300 and the connector assembly 200 is restricted by the frame 400. When the side fastener 22 is subjected to force and elastically deforms in a direction away from the side wall body 111 , the side retaining portions 113 withdraw from the first buckle holes 221 a , that is, the side fastener 22 is released from the side retaining portions 113 .

5 and 6 , each of the first stoppers 23 has a guide groove 231 opening toward the first guide surface 113a (i.e., forward). The guide grooves 231 extend along the front-rear direction X and allow the protrusions 112 to slide in relative forward and backward movements, so that the frame 400 is limited in upward and downward movement during the sliding movement of the protrusions 112 relative to the guide grooves 231. Specifically, during the process of assembling the liquid cooling plate 300 to the connector assembly 200 via the frame 400, the frame 400 is first operated and moved downward as indicated by the solid arrow in FIG. 6 until the opening of the guide groove 231 is aligned with the protrusion 112. Then, the frame 400 is continuously operated and moved forward (opposite to the direction indicated by the arrow in the front-rear direction X in FIG. 6) as indicated by the solid arrow in FIG. 6, so that the first stopper 23 slides relative to the protrusion 112 and the protrusion 112 slides into the guide groove 231. Finally, at the protrusion 112, the first stopper 23 slides relative to the protrusion 112. When the side fasteners 22 are inserted into the end of the guide groove 231, the side fasteners 22 are resisted and applied by the side retaining portions 113 and are elastically deformed along the first guide surfaces 113a in a direction away from the outer surface of the side wall body 111, so that the first buckle holes 221a can be penetrated by the side retaining portions 113, respectively, and the liquid cooling plate 300 is combined with the connector assembly 200. In this way, the liquid cooling plate 300 can be assembled on the connector assembly 200 through the frame 400 in a tool-free and screw-free process, thereby achieving an effect of improving assembly convenience.

Preferably, the rear wall 12 has a rear wall body 121 and two rear retaining portions 122 protruding outward (i.e., backward) from the outer surface of the rear wall body 121 in the front-rear direction X and arranged side by side on the left and right. The rear frame 4 has two rear positioning holes 42 arranged on the left and right and penetrated from the front and rear. The rear positioning holes 42 can allow the rear retaining portions 122 to penetrate from the front to the rear, respectively, so that the rear fastener 43 is restricted by the rear retaining portions 122 to move up, down, left, and right, respectively. In this way, as shown in FIG. 6 , when the frame 400 is operated to move forward, the rear retaining portions 122 will penetrate the rear positioning holes 42 respectively, so as to achieve the effect of restricting the movement of the frame 400 and improve the stability of the assembly.

Referring to FIGS. 7 to 14 , a second embodiment of the connection device of the present invention is shown. The connection device is similar to the first embodiment, and includes a circuit board 100, a connector assembly 200 ′, a liquid cooling plate 300, a frame 400 ′, and a plurality of screws. One difference between the connection device and the first embodiment is that each side wall 11 ′ of a metal shell 1 ′ of the connector assembly 200 ′ has a side wall body 111, two side retaining portions 113 ′ disposed at the front and rear, a lower stop portion 114, and a side stop portion 115. Each side retaining portion 113 ′ has a first guide surface 113 a ′ extending outward (i.e., away from the side wall body 111) and downward. The lower stopper 114 is located between the two side holding portions 113'. The side stopper 115 is disposed between the front and rear sides of the lower stopper 114 and the adjacent side holding portions 113'.

Another difference between the connecting device and the first embodiment is that each side frame 2' of the frame 400' has a side frame body 21, two side fasteners 22' extending downward from the bottom edge of the side frame body 21 and arranged front and rear, and a second stopper 24. The side fasteners 22' can be elastically deformed under force, and have a first buckle hole 221a' through which the side retaining portions 113' can be respectively inserted. Each side buckle body 221 is formed with the first buckle hole 221a'. Each second stopper 24 has an extension portion 241 extending downward, and abutment portion 242 extending inward from the bottom of the extension portion 241.

Referring to FIGS. 11 to 14 , during the process of assembling the liquid cooling plate 300 to the connector assembly 200 ′ via the frame 400 ′, the frame 400 ′ is operated to move downward as indicated by the solid arrow in FIG. 14 . At this time, the side locking fasteners 22 ′ are subjected to force and elastically deform along the first guide surfaces 113 a ′, respectively, so that the first buckle holes 221 a ′ can be respectively penetrated by the side retaining portions 113 ′. The fasteners 22' are restricted by the side retaining portions 113' in upward, downward, forward and backward movement, that is, the side locking fasteners 22' are respectively fastened to the side retaining portions 113', so that the liquid cooling plate 300 is assembled to the connector assembly 200' through the frame 400' and combined with the connector assembly 200', and the relative displacement of the liquid cooling plate 300 and the connector assembly 200' is restricted by the frame 400'. At the same time, the abutting portion 242 of the second stopper 24 is pressed against the lower stopper 114 to limit downward movement, and the inner wall bottom edge of the first buckle hole 221a' is pressed against the bottom surface of the side retaining portion 113' to limit upward movement, thereby preventing the frame 400' from shaking up and down relative to the connector assembly 200' after assembly. Preferably, the second stopper 24 is an elastic member. In addition, in the second embodiment, when the frame 400' drives the liquid cooling plate 300 from top to bottom and approaches the connector assembly 200', the side locking fastener 22' will slide downward along the side edge of the side blocking portion 115 and be restricted by the side blocking portion 115, so that the side locking fastener 22' cannot move forward or backward, but can be guided toward the side retaining portion 113'.

Preferably, each of the side fasteners 22' has a side fastener body 221 and a first fastener guide portion 222 extending downward and outward (i.e., away from the side frame body 21) from the bottom of the side fastener body 221. When the frame 400' drives the liquid cooling plate 300 to approach the connector assembly 200' from top to bottom, the first fastener guide portion 222 is pushed against by the side retaining portion 113' and drives the side fastener body 221 to deform elastically outward, which facilitates the side fastener 22' to be fastened to the side retaining portion 113'.

Another difference between the connecting device and the first embodiment is that a rear wall 12' of the metal shell 1' has a rear wall body 121 and two rear retaining parts 122' arranged on the left and right of the rear wall body 121. Each rear retaining part 122' has a second guide surface 122a' extending downwardly from the outer surface of a rear wall body 121 of the rear wall 12 outwardly (i.e., away from the rear wall body 121). In addition, a rear frame 4' of the frame 400' has a rear frame body 41, two rear fasteners 43 arranged on the left and right, and two pressing parts 44 arranged on the left and right. The rear fastener 43 extends downward and can be elastically deformed under force. Each of the rear fasteners 43 has a second buckle hole 431a which is penetrated by the front and rear surfaces and can allow the rear retaining portion 122' to penetrate. The rear fasteners 43 are subjected to force and elastically deform along the second guide surface 122a', so that the second buckle hole 431a can be penetrated by the rear retaining portion 122'. The rear fasteners 43 are restricted by the rear retaining portion 122' to move up, down, left, and right, that is, the rear fasteners 43 are buckled to the rear retaining portion 122', so that the rear side of the liquid cooling plate 300 is also assembled to the connector assembly 200' through the frame 400', and is more stable.

Preferably, each rear fastener 43 further comprises a rear fastener body 431 and a second fastener guide portion 432 extending downward and outward from the bottom of the rear fastener body 431. The rear fastener body 431 is formed with the second fastener hole 431a. When the frame 400' drives the liquid cooling plate 300 to approach the connector assembly 200' from top to bottom, the second fastener guide portion 432 is respectively pushed by the rear retaining portion 122' to drive the rear fastener body 431 to deform elastically outward, which is conducive to the rear fastener 43 being fastened to the rear retaining portion 122'.

Furthermore, each of the pressing members 44 has a plate portion 441 extending downward and capable of elastic deformation, a convex strip 442 extending from the plate portion 441 toward the direction close to the rear wall 12', and a convex rib 443 extending from the plate portion 441 toward the direction away from the rear wall 12' and located above the convex strip 442. When the frame 400' drives the liquid cooling plate 300 from top to bottom and approaches the connector assembly 200', the convex strip 442 is subjected to the force of the rear wall 12' and drives the plate portion 441 to elastically deform in a direction away from the rear wall 12', and generates a first elastic restoring force forward, which allows the frame 400' to be closely pressed against the connector assembly 200' forward, so that the frame 400' is more stably assembled on the connector assembly 200'. The convex rib 443 is used to strengthen the structure of the pressing member 44 so that the pressing member 44 is not easily deformed.

Preferably, each of the side frames 2' further has a guide member 25. The guide member 25 has a spring portion 251 extending downward, a pressing portion 253 extending downward from the spring portion 251 toward the side wall 11, and a guide portion 254 extending downward and outward from the bottom of the pressing portion 253. The spring portion 251 can be elastically deformed under force. The length of the guide member 25 extending downward is greater than the length of the side fastener 22' extending downward. Thus, when the frame 400' drives the liquid cooling plate 300 to approach the connector assembly 200' from top to bottom, the guide portion 254 will touch the connector assembly 200' more than the side fastener 22'. At this time, the guide portion 254 is respectively pressed against the top edge of the side wall 11' to drive the elastic sheet portion 251 to elastically deform in a direction away from the side wall 11', and generate a second elastic restoring force inward. The second elastic restoring force allows the pressing portion 253 to press against the side wall 11', respectively, to prevent the frame 400' from shaking left and right.

In summary, by fastening the side fasteners 22, 22' to the side retaining portions 113, 113', the liquid cooling plate 300 can be directly assembled to the connector assemblies 200, 200' through the frames 400, 400', so that the liquid cooling plate 300 and the connector assemblies 200, 200' are tightly combined, without increasing the board area occupied by the circuit board 100, and the step of locking screws can be omitted, thereby achieving the effect of improving assembly convenience. In addition. By designing the guide groove 231 or the first guide surfaces 113a, 113a', the assembly direction of the frame 400 can be guided, and the assembly convenience can also be improved. On the other hand, by accommodating the liquid cooling plate 300 in the accommodating space 5, and the frames 400, 400' are fixed to at least three sides of the liquid cooling plate 300, the liquid cooling plate 300 can be stably assembled on the frames 400, 400'.

However, the above is only an embodiment of the present invention and should not be used to limit the scope of 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 present patent.
