Technical Field

[0002] The SFP optical module is a hot-swappable module used for data transmission. The SFP module mainly includes a metal shell, an optical module body located inside the metal shell, and a port for plugging and unplugging connections.

[0003] During the signal transmission process of the SFP optical module, a large amount of heat will be generated. If the high temperature cannot be dissipated in time, it will seriously affect the signal transmission efficiency of the SFP optical module. In addition, if the optical module works in a high temperature environment for a long time, it will also greatly affect the life of the optical module.

[0004] At present, there is no special heat dissipation structure for SFP optical modules. Usually, they are placed in a cool and ventilated place to dissipate heat naturally by air flow. However, this heat dissipation method is inefficient and cannot dissipate heat for the optical module in a timely and fast manner.

[0005] Therefore, there is an urgent need for a structure capable of dissipating heat for the SFP. Utility Model Content

[0010] A clamping piece is used to clamp the heat sink onto the shell body so that the heat sink and the shell body fit tightly together. The clamping piece includes two connecting parts that are respectively engaged with the two side surfaces of the shell body, and an elastic clamping arm is formed between the connecting parts to press the heat sink toward the shell body.

[0011] Furthermore, the connecting portion is in the form of an elongated strip, on which a plurality of slots are provided, and a clamping block that is mutually clamped with the slots is provided on the side wall of the shell body.

[0012] Furthermore, the elastic clamp arm is formed with

[0013] A docking section, one end of which is formed on the side edge of the connecting portion, and the other end of which extends toward the center line of the elastic clamp arm;

[0014] An extension section, one end of which is formed on the docking section and arranged in a horizontal direction;

[0015] An elastic section, one end of which is formed on the extension section and is inclined toward an edge of the connecting portion away from the elastic clamp arm;

[0016] The pressing part is arranged in a horizontal direction, and two ends of the pressing part are respectively formed on the two elastic sections.

[0017] Furthermore, a channel for the elastic clamp arm to pass through is formed on the heat dissipation block.

[0018] Furthermore, a window communicating with the chamber is provided on any one of the side walls of the shell body, and a side plate extending upward and correspondingly engaged with the connecting portion is formed at the edge of the window, and the heat dissipation block stacked with the side wall having the window is formed with a probing portion corresponding to the window, and limiting portions located at both ends of the probing portion, and the probing portion protrudes into the interior of the chamber along the window.

[0020] The beneficial effects produced by the utility model are as follows:

[0027] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0028] The present invention provides an SFP heat dissipation structure, which can enhance the heat dissipation performance of the SFP optical module. Figure 1-4 As shown, an SFP heat dissipation structure provided by an embodiment of the utility model includes a shell 10 for installing an SFP optical module, the shell 10 includes a shell body 11, a heat sink 20 and a clamping member 30; a chamber 12 for installing the SFP optical module is formed inside the shell body 11; the heat sink includes two heat sinks stacked on two corresponding side walls 13 of the shell body 11, and a plurality of heat dissipation protrusions 21 are formed on the side of the heat sink away from the shell body 11; the clamping member 30 is used to clamp the heat sink 20 on the shell body 11 so that the heat sink 20 and the shell body 11 fit tightly, and the clamping member 30 includes two connecting parts 31 respectively clamped with the two side surfaces of the shell body 11, and an elastic clamping arm 32 is formed between the connecting parts 31 to press the heat sink 20 toward the shell body 11.

[0029] A plurality of heat dissipation protrusions 21 are formed on the heat dissipation block 20, so as to increase the contact surface with the air, so that heat can be transferred to the air through the heat dissipation protrusions 21, thereby realizing heat dissipation of the SFP optical module, and by arranging the heat dissipation protrusions 21 in a matrix, the strength of the heat dissipation block 20 can be enhanced, thereby improving the strength of the shell, and ensuring the performance of the optical module. The heat dissipation block 20 is installed on the shell body 11 through the clamping member 30, and can be in close contact with the shell body 11 under the tightening of the elastic clamping arm 32, thereby ensuring that heat can be quickly transferred to the heat dissipation block 20 and dissipated through the heat dissipation protrusions 21.

[0030] In this embodiment, if Figure 2-3As shown, the connecting portion 31 is in a long strip structure, and a plurality of slots 311 are formed on the connecting portion 31, and a clamping block 14 is formed on the side wall 13 of the shell body 11 to be mutually engaged with the slots 311. By mutually engaging the connecting portion 31 and the side wall 13, the heat sink 20 is clamped on the shell body 11, and the connection method of the clamping member 30 is simple, and the fixing performance is reliable.

[0031] In this embodiment, if Figure 3 As shown, the elastic clamp arm 32 is sequentially formed with a docking section 321, an extension section 322, an elastic section 323 and a clamping portion 324 from both ends to the center line direction, one end of the outer side of the docking section 321 is formed on the side edge of the connecting portion 31, and the other end of the docking section 321 extends toward the center line direction of the elastic clamp arm 32; one end of the extension section 322 is formed on the docking section and is arranged in a horizontal direction; one end of the elastic section 323 is formed on the extension section 322 and is inclined toward the edge of the connecting portion 31 away from the elastic clamp arm 32; the clamping portion 324 is arranged in a horizontal direction, and its two ends are respectively formed on the two elastic sections 323.

[0032] In the process of clamping the heat sink 20, the connecting portion 31 is pressed toward the shell body 11, so that the pressing portion 324 is in contact with the heat spreading block in advance, and as the connecting portion 31 is continuously pressed toward the clamping block 14, the elastic segment 323 undergoes elastic deformation in the opposite direction, and generates an elastic force that pushes the heat sink 20 toward the shell body 11. Under the action of the elastic force, the heat sink 20 is pressed onto the shell body 11, and the clamping block 14 is clamped into the clamping groove 311 to fix the heat sink 20.

[0033] Correspondingly, a channel 22 for the elastic clamp arm to pass through is formed on the heat dissipation block 20 .

[0034] In this embodiment, in order to further increase the heat dissipation effect of the optical module, as shown in FIG. Figure 2-4 As shown, a window 15 communicating with the chamber 12 is formed on any one of the side walls 13 of the shell body 11, and a side plate 16 extending upward and correspondingly engaged with the connecting portion 31 is formed at the edge of the window 15, and the heat dissipation block 20 stacked with the side wall 13 having the window 15 is formed with a probe portion 23 corresponding to the window 15, and limiting portions 24 located at both ends of the probe portion 23, and the probe portion 23 probes into the interior of the chamber 12 along the window 15.

[0035] That is to say, the heat sink 20 extends into the chamber 12 through the window 15 and directly contacts the hot air in the chamber 12, thereby preventing the hot air from being transferred to the heat sink 20 through the side wall 13, thereby improving the heat dissipation efficiency of the hot air.

[0036] In this embodiment, in order to further improve the heat dissipation effect, the heat dissipation block 20 is coated with heat dissipation.
