[0001] This utility model relates to a connector structure, and more particularly to a cable connector with heat dissipation function. Background Technology

[0002] Connectors are widely used in various fields, resulting in a variety of different connectors. Among them, cable connectors are mainly used to effectively connect cables, connecting multiple cables in a cable harness to the tongue plate of the mating end, so as to connect with another mating connector to transmit signals, ensuring complete signal transmission and minimal loss.

[0003] However, with the increasing demands for data processing speed, transmission rate, and capacity, the heat generated by cable connectors during operation also increases. If corresponding heat dissipation methods are not provided, the efficiency of the cable connectors will be significantly affected, and short circuits or damage may even occur. Therefore, how to provide cable connectors with effective heat dissipation methods is the focus of this invention's research and development.

[0004] In view of this, the inventor of this utility model has devoted himself to researching and applying theoretical principles to solve the aforementioned problems in the existing technology, which is the goal of the inventor's improvement. Utility Model Content

[0005] This utility model provides a cable connector with heat dissipation function, which utilizes a heat dissipation fin assembly installed on the housing to be directly heat-attached to the heat-generating element, so as to achieve excellent heat dissipation efficiency of the cable connector.

[0041] The detailed description and technical content of this utility model will be explained in conjunction with the drawings below. However, the drawings are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0042] Please refer to Figures 1 to 3 As shown, this utility model provides a cable connector with heat dissipation function. The cable connector 10 mainly includes a housing 1, a circuit board module 2 and a heat dissipation fin group 3.

[0043] like Figures 1 to 3 As shown, the housing 1 has a mating end 11, a wiring end 12 and a top 13. The wiring end 12 is formed at the end of the housing 1 away from the mating end 11. The detailed description is as follows: In this embodiment, the mating end 11 and the wiring end 12 are two openings formed at the front and rear ends of the housing 1 (not labeled in the figure), but this is not a limitation.

[0044] In addition, the housing 1 includes an upper housing 15 and a lower housing 16 connected together. The top 13 of the upper housing 15 is provided with a through opening 131 and two side plates 14 extending therefrom. The upper housing 15 has a first edge section 132 and a second edge section 133 disposed on both sides of the through opening 131. The lower end of the first edge section 132 is provided with a groove 1321, and the second edge section 133 is provided with a plurality of first locking holes 1331.

[0045] like Figures 2 to 3 As shown, circuit board module 2 is disposed within housing 1. Circuit board module 2 includes a circuit board 21 and a heating element 22 mounted on the circuit board 21. Circuit board 21 has a tongue 211 exposed at the mating end 11, that is, an opening at the front end of the tongue 211 exposed at the front end of housing 1. Heating element 22 is configured opposite to the opening 131. The heating element 22 can be an electronic component such as an IC chip that easily generates high temperatures during operation.

[0046] like Figures 1 to 3 As shown, the heat dissipation fin assembly 3 is made of heat dissipation material such as copper or aluminum. The heat dissipation fin assembly 3 is embedded in the opening 131 and thermally attached to the heat-generating element 22. The heat dissipation fin assembly 3 has multiple heat dissipation fins 31, and multiple heat dissipation channels S are formed between the multiple heat dissipation fins 31.

[0047] The further description is as follows. The heat dissipation fin group 3 is disposed between the two side plates 14, that is, the two side plates 14 are disposed on both sides of the heat dissipation fin group 3. The two side plates 14 are arranged in parallel with the plurality of heat dissipation fins 31 and can stop and position the heat dissipation fin group 3. The heat dissipation fin group 3 has a bottom plate 32, and the plurality of heat dissipation fins 31 extend upward from the bottom plate 32. A heat conduction block 321 extends upward from the bottom plate 32, and the heat conduction block 321 is thermally bonded to the heating element 22.

[0048] Furthermore, the heat dissipation fin group 3 further has a top plate 33. The tops of the plurality of heat dissipation fins 31 are integrally extended and formed with the top plate 33, and the bottoms of the plurality of heat dissipation fins 31 are integrally extended and formed with the bottom plate 32. Also, one end opening of the heat dissipation channel S is disposed opposite to the docking end 11, and the other end opening is disposed opposite to the wiring end 12, so that the heat dissipation air flow in the heat dissipation channel S cannot escape upward and downward, and the heat dissipation air flow in the heat dissipation channel S can only escape toward the docking end 11 and the wiring end 12.

[0049] As Figures 1 to 3 shown, the cable connector 10 of the present invention further includes one or more cables 4. The cables 4 are disposed through the wiring end 12, that is, the cables 4 are disposed through the opening at the rear end of the housing 1, and the core wires 41 of the cables 4 are electrically connected to the circuit board 21.

[0050] As Figures 2 to 3 shown, the cable connector 10 of the present invention further includes a plurality of screws 5. One end of the bottom plate 32 of the heat dissipation fin group 3 extends with a protruding piece 322, and the other end is provided with a plurality of second locking holes 323. The protruding piece 322 is engaged with the concave groove 1321, and each screw 5 is locked to each first locking hole 1331 and each second locking hole 323, so that one end of the bottom plate 32 of the heat dissipation fin group 3 is engaged with the first edge segment 132, and the other end is locked to the second edge segment 133, so that the heat dissipation fin group 3 can be detachably fixed to the housing 1.

[0051] Also, in this embodiment, the upper housing 15 extends downward with a plurality of fixing columns (not labeled in the figure) respectively disposed through each first locking hole 1331, and each second locking hole 323 is opened from each fixing column. When each screw 5 is locked to each first locking hole 1331 and each second locking hole 323, the head of the screw 5 can be hidden below the upper housing 15, that is, the head of the screw 5 can be hidden inside the housing 1.

[0052] The detailed description is as follows. One end of the heat dissipation fin group 3 of the present invention is first engaged with the concave groove 1321 through the protruding piece 322, and the other end is then locked to the upper housing 15 through the screw 5, so that the heat dissipation fin group 3 is first fixed to the upper housing 15, and then the upper housing 15 and the lower housing 16 are assembled up and down, thereby completing the assembly of the housing 1.

[0053] As Figure 2As shown, the cable connector 10 of the present utility model further includes a thermal conductive adhesive 6. The thermal conductive adhesive 6 is attached between the heat conducting block 321 and the heating element 22. The thermal conductive adhesive 6 is used to sequentially transfer the heat generated by the heating element 22 to the heat conducting block 321, the bottom plate 32, and the multiple heat dissipation fins 31 for heat dissipation. Among them, the thermal conductive adhesive 6 is a non-essential component and can be omitted according to actual situations or replaced with heat dissipation paste.

[0054] As Figures 1 to 3 shown, in the usage state of the cable connector 10 of the present utility model, the heat dissipation fin group 3 is embedded in the through hole 131 and thermally connected to the heating element 22, so that the heat generated by the heating element 22 is directly transferred to the heat dissipation fin group 3 made of heat dissipation materials such as copper or aluminum, thereby effectively helping the heating element 22 dissipate heat, so as to achieve excellent heat dissipation efficiency of the cable connector 10.

[0055] In addition, since there are various types of installation positions, sizes, and quantities of the heat dissipation fins 31 on the circuit board 21, but the heat dissipation fin group 3 of the present utility model can be disassembled and replaced relative to the housing 1 to replace the heat conducting block 321 that can be firmly attached to the heating element 22. Therefore, the present utility model only needs to manufacture the heat dissipation fins 31 with different specifications of the heat conducting blocks 321 to adapt to the heat dissipation of various specifications of heat dissipation fins 31 on the market, thereby improving the universality and convenience of use of the cable connector 10.

[0056] Furthermore, since the cable connector 10 of the present utility model is mostly inserted into a device (not shown in the figure), one end opening of the heat dissipation channel S is arranged opposite to the docking end 11 and the other end opening is arranged opposite to the wiring end 12, which can guide the heat dissipation air flow in the heat dissipation channel S to dissipate in the directions of the docking end 11 and the wiring end 12, avoiding the heat dissipation air flow in the heat dissipation channel S from dissipating upward and downward and heat accumulating on the device or the cable connector 10.

[0057] In summary, the cable connector with a heat dissipation function of the present utility model can indeed achieve the expected usage purpose, solve the conventional deficiencies, and has industrial applicability, novelty, and progressiveness, fully meeting the patent application requirements. Therefore, an application is filed according to the Patent Law to protect the rights of the utility model people.
