Background Art

[0002] The existing electrical connector module with multiple high-power electrical connectors usually has a metal shell for accommodating multiple electrical connectors and for supporting the installation of multiple heat sinks for dissipating heat from the electrical connectors, and the metal shell also plays the role of electromagnetic shielding. In order to fix the multiple heat sinks on the metal shell and keep them in thermal contact with the electrical connectors, the existing structure is to set positioning protrusions on two opposite outer sides of the metal shell, and a clip simultaneously abuts against the multiple heat sinks and its two ends are respectively positioned and engaged with the positioning protrusions set on the two opposite outer sides of the metal shell, so as to position the heat sink on the metal shell and apply pressure to the heat sink, so that the heat sink is pressed against the electrical connector to form a thermal contact structure with good thermal conductivity. However, since the existing clip is used to press all the heat sinks at one time and must be positioned according to the size of the metal shell, when the number of electrical connectors is different and metal shells of different sizes are used accordingly, it is also necessary to make a clip corresponding to the size of the metal shell, which will increase the production cost of the overall electrical connector module or reduce the flexibility in design. Summary of the invention

[0003] The embodiments of the present application provide an electrical connector module and a heat dissipation housing, which solve the problem that the buckle of the existing heat dissipation housing must correspond to the size of the metal shell, resulting in increased cost and reduced design flexibility.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0015] like Figure 2 and Figure 3As shown, the positioning component 40 includes a component body 41 and a plurality of positioning members 42. The component body 41 is disposed on the setting surface 111 and has a plurality of second openings 411. The plurality of second openings 411 correspond to the plurality of first openings 113 respectively, and the area of ​​the second openings 411 is greater than the area of ​​the first openings 113. The two opposite sides of each second opening 411 are respectively connected to at least one positioning member 42. The component body 41 is fixed to the setting surface 111 of the shell body 11 by, for example, welding or gluing. The second opening 411 has two oppositely disposed long sides 4111 and two oppositely disposed short sides 4112. The positioning member 42 is connected to the two oppositely disposed long sides 4111 of the second opening 411. In this embodiment, the positioning member 42 is a sheet-like structure formed by bending a portion of the protruding structure of the component body 41 located at the long side 4111 of the second opening 411 upward, so the positioning member 42 of this embodiment is integrally formed with the component body 41.

[0016] like Figure 3 As shown, each positioning member 42 includes a positioning sheet 421 and a positioning protrusion 422. The positioning sheet 421 is connected to the two opposite long sides 4111 of the second opening 411 and extends in a direction away from the setting surface 111. The positioning protrusion 422 is arranged on the surface of the positioning sheet 421 away from the second opening 411 and protrudes in a direction away from the second opening 411. The latch 30 is engaged with the positioning protrusion 422.

[0017] A plurality of electrical connectors are disposed in the accommodation space 112 of the shell body 11, and correspond to the plurality of first openings 113, respectively. In the present embodiment, the plurality of electrical connectors are arranged parallel to each other in the accommodation space 112, and the long sides 1131 of the plurality of first openings 113 and the long sides 4111 of the second openings 411 are also arranged parallel to each other, and the positions of the first openings 113 correspond to the electrical connectors, so that the housing of the electrical connector can be exposed through the first openings 113 and the second openings 411. The metal shell 10 also has a plug-in interface 114, which is located in a plane orthogonal to the setting surface 111, and the interface of the electrical connector can be exposed through the plug-in interface 114, and each electrical connector includes a plurality of terminals, and the plurality of terminals correspond to the plug-in interface 114 so that the corresponding other plurality of electrical connectors pass through the plug-in interface 114 and plug into the electrical connector disposed in the metal shell 10. In the present embodiment, the electrical connector disposed in the metal shell 10 is a female electrical connector.

[0018] like Figure 1 , Figure 3 and Figure 4As shown, a plurality of heat sinks 20 are respectively disposed at a plurality of second openings 411 and are in thermal contact with a plurality of electrical connectors through a plurality of first openings 113 and a plurality of second openings 411, respectively. Each heat sink 20 is located between two positioning members 42 disposed at two opposite long sides 4111 of each second opening 411. In this embodiment, each heat sink 20 includes a base 21 and a plurality of heat sink fins 22. The base 21 is rectangular and disposed on the component body 41 of the positioning component 40. The base 21 covers the second openings 411 and contacts the housing of the electrical connector exposed from the second openings 411 through the second openings 411, thereby forming a heat conduction structure. The heat generated by the electrical connector due to the transmission of high-frequency signals is conducted from the housing of the electrical connector to the base 21 and the heat sink fins 22 of the heat sink 20, and then carried away by the airflow passing through the heat sink fins 22 in a heat convection manner through the heat sink fins 22.

[0019] like Figure 1 , Figure 3 and Figure 4 As shown, each buckle 30 connects and positions each heat sink 20 to two positioning members 42 disposed on two opposite long sides 4111 of each second opening 411. Figure 3 As shown, in this embodiment, the buckle 30 includes two positioning portions 31 and at least one limiting portion 32, the two positioning portions 31 respectively correspond to the two positioning members 42 provided at the two opposite long sides 1131 of each first opening 113, and the two positioning portions 31 are respectively engaged with the positioning protrusions 422 of the positioning member 42, and the limiting portion 32 connects the two positioning portions 31. In this embodiment, there are two limiting portions 32. The positioning portion 31 is parallel to the long side 4111 of the second opening 411, and the limiting portion 32 is parallel to the short side 4112 of the second opening 411.

[0020] like Figure 1 and Figure 3 As shown, each heat sink 20 is disposed between two positioning portions 31 and between the limiting portion 32 and the second opening 411. After the positioning portion 31 is engaged with the positioning protrusion 122 of the positioning member 42, the limiting portion 32 is pressed against the heat sink 20, so that the heat sink 20 remains in contact with the electrical connector, thereby forming the aforementioned heat conduction structure. Figure 3 As shown, the limiting portion 32 has a structure approximately in a shallow U shape, and the concave portion in the center of the limiting portion 32 can be pressed against the heat sink 20. Each heat sink 20 has a limiting groove 23, which is arranged between two groups of adjacent heat sink fins 22. The limiting portion 32 of the buckle 30 passes through the limiting groove 23 and is pressed against the base 21 of the heat sink 20. The extending direction of the limiting groove 23 is parallel to the short side 4112 of the second opening 411.

[0021] like Figure 1 , Figure 2and Figure 3 As shown, in this embodiment, the two positioning portions 31 are sheet-like structures, and one side thereof abuts against the component body 41 of the positioning component 40, and the side thereof away from the component body 41 has at least one positioning notch 311, and at least one positioning notch 311 engages with the positioning protrusion 422 from one end of the positioning protrusion 422 close to the component body 41, so that the positioning protrusion 422 restricts the positioning portion 31 and prevents the buckle 30 from being separated from the positioning member 42, thereby positioning the buckle 30 on the positioning member 42. In this embodiment, each positioning portion 31 has two positioning notches 311.

[0022] like Figure 3 and Figure 4 As shown, each positioning portion 31 of the buckle 30 further includes a positioning notch 312, which is arranged on the same side as the positioning notch 311, and is used to position the light pipe passing through the top of the heat sink 20. The heat sink 20 is provided with a guide groove 24 between the two limiting grooves 23, and the guide groove 24 enables the light pipe to extend through the heat sink 20 and be positioned in the positioning notch 312 of the positioning portion 31 of the buckle 30.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the electrical connector module of this embodiment also includes a plurality of partition plates 50, which are arranged in the accommodating space 112 of the shell body 11, and divide the accommodating space 112 into a plurality of separated spaces, and each electrical connector is arranged in the separated space between two adjacent partition plates 50. The partition plates 50 can be made of conductive materials, so that they can play a role of electromagnetic shielding for adjacent electrical connectors. Each partition plate 50 has a plurality of fixing portions 51, and the plurality of fixing portions 51 pass through the shell body 11 and are fixed to the setting surface 111 between two adjacent first openings 113. Because the positioning portion 31 of the snap member 30 abuts against the setting surface 111, and in this embodiment, the fixing portions 51 of the partition plate 50 extend toward the positioning members 42 in opposite directions respectively, so that the positioning portion 31 of the snap member 30 is crimped on the fixing portion 51. As shown Figure 2 and Figure 4 As shown, the component body 41 of the positioning component 40 also has a plurality of clearance holes 412, and the plurality of clearance holes 412 correspond to the plurality of fixing parts 51. When the positioning component 40 is fixed on the setting surface 111 of the shell body 11, the clearance holes 412 allow the fixing parts to pass through so that the component body 41 of the positioning component 40 can be fixed flatly on the setting surface 111.

[0024] like Figure 1 , Figure 3 and Figure 4As shown, the electrical connector module of this embodiment further includes a circuit board 60, and the metal housing 10 is disposed on the circuit board 60, for example, fixed on the circuit board 60 by a plug-in connector having a fisheye structure. The terminals of the plurality of electrical connectors are electrically connected to the circuit board 60 by being welded thereon.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the electrical connector module of this embodiment further includes a snap-fastener 70, which is disposed on the setting surface 111 of the shell body 11. The snap-fastener 70 is used to position the metal shell 10 against the shell of the electronic device when the metal shell 10 is plugged into the shell of the electronic device.

[0026] In summary, the present application provides an electrical connector module and a heat dissipation housing, by providing positioning members on two opposite sides of each second opening of a positioning assembly of a heat dissipation member, so that the snap-fit ​​members only need to be made corresponding to the size of the second opening. Even if the metal shell has different sizes corresponding to the number of electrical connectors, snap-fit ​​members of the same size can be used, as long as the number of snap-fit ​​members is increased or decreased, and there is no need to make different snap-fit ​​members corresponding to the size of the metal shell as in the prior art, thereby reducing the manufacturing cost and providing flexibility in design. In addition, the size of the second opening of the positioning assembly can be made corresponding to the size of the first opening, which makes the design more flexible.
