[0030] The following will be combined Figures 1 to 11 The specific implementation of the electric connector and its combination of the utility model are introduced.
[0031] See also Figures 1 to 4 The utility model discloses an electrical connector assembly 1000, including an electrical connector 100 and a heat dissipation module 200. The electrical connector 100 is installed on a circuit board 300. The heat dissipation module 200 can contact an electronic card 400 inserted into the electrical connector 100 to help the electronic card 400 dissipate heat.
[0032] Combination Figure 4 and Figure 5The electrical connector 100 is provided with a card slot 11 and a plurality of terminals 20 extending into the card slot 11. The electrical connector 100 includes a support surface 31 located above the card slot 11 and a first magnetic attraction member 40 exposed to the support surface 31. The heat dissipation module 200 includes an abutment surface 51 and a second magnetic attraction member 52 exposed to the abutment surface 51. Fig.11 When the abutting surface 51 of the heat dissipation module 200 is mounted on the supporting surface 31, the first magnetic attraction member 40 and the second magnetic attraction member 52 attract each other, so that the heat dissipation module 200 is assembled to the electrical connector 100. Since the electrical connector 100 and the heat dissipation module 200 are assembled by magnetic attraction, no other assembly tools are required, and the operation is simple and convenient.
[0033] See also Figure 3 and Figure 4 The electrical connector 100 is provided with two first magnetic members 40, and the heat dissipation module 200 is correspondingly provided with two second magnetic members 52, so that the electrical connector 100 and the heat dissipation module 200 have a better positioning effect during assembly. In this embodiment, the first magnetic member 40 is an iron member, and the second magnetic member is a magnet 52.
[0034] like Figures 5 to 7 As shown, the electrical connector 100 includes an insulating body 10, the terminal 20 and a metal shell 30. The insulating body 10 is provided with a front face 12 and a rear face 13 opposite to each other, a top face 14 and a bottom face 15 located between the front and rear faces, the slot 11 passes through the front face 12, the top face 13 is provided with a fence portion 131, the first magnetic member 40 is accommodated in the fence portion 131, the metal shell 30 includes a top plate 310 attached to the top face 14 of the insulating body, the support surface 31 is formed on the top plate 310 and is provided with a through hole 32, the first magnetic member 40 is exposed in the through hole 32. The first magnetic member 40 includes a base 41 and a boss 42 protruding upward from the base 41, the inner edge of the through hole 32 is provided with a rib 320, the base 41 is accommodated in the fence portion 131, and the boss 42 is interfered and fixed to the rib 320 so that the first magnetic member 40 is fixed to the metal shell 30. In a preferred embodiment, the first magnetic member 40 is recessed in the support surface 31 or flush with the support surface 31 to protect the first magnetic member 40 from being easily damaged. It should be noted that although the first magnetic member 40 can be recessed in the support surface 31, the recessed distance is much smaller than the thickness of the first magnetic member 40 in the recessed direction, so it will not affect the magnetic attraction effect of the first magnetic member 40.
[0035] like Figure 3 , Figure 4 and Figures 8 to 10As shown, the heat dissipation module 200 includes a magnetic attraction kit 50 and a heat dissipation plate 60. The lower surface 61 of the heat dissipation plate 60 is concavely provided with a platform portion 62. The magnetic attraction kit 50 is assembled on the platform portion 62. The platform portion 62 is provided with a protrusion 621 protruding downward. The upper surface of the magnetic attraction kit 50 is provided with a notch portion 53. The protrusion 621 is accommodated in the notch portion 53. Fig. 9 The protrusion 621 and the notch 53 extend from the assembly direction of the magnetic attraction kit 50, and the platform 62 is connected to the lower surface 61 of the heat sink 60 through a step surface 63. In this embodiment, the magnetic attraction kit 50 is assembled close to the step surface 63. Figure 2 , along the assembly direction, the splicing edge of the step surface 63 and the magnetic attraction kit 50 is the first edge 64, and the splicing edge of the protrusion 621 and the notch 53 is the second edge 65. The first edge 64 and / or the second edge 65 are arranged obliquely, so that the magnetic attraction kit 50 is not easy to fall off from the heat sink 60, which is conducive to improving the reliability of the assembly of the magnetic attraction kit 50 and the heat sink 60. In this embodiment, in order to enhance the fixing effect, the heat dissipation module 200 further includes a screw 70, and the screw 70 fixes the magnetic attraction kit 50 and the heat sink 60 together.
[0036] See also Fig. 9 and Fig.10 The magnetic attraction kit 50 includes a main body 54 and the second magnetic attraction member 52. The main body 54 includes the upper surface 541 and the abutting surface 51 relative to each other and is provided with a mounting groove 542 which passes through the upper surface 541 and the abutting surface 51 from top to bottom. Since the magnet is easily broken when hit, the second magnetic attraction member 52 is assembled in the mounting groove 542 and retracted into the abutting surface 51. When the heat dissipation module 200 is assembled with the electrical connector 100, the magnet will not be damaged. It should be noted that although the second magnetic attraction member 52 is retracted into the abutting surface 51, the retracted distance is much smaller than the thickness of the second magnetic attraction member 52 in the retracted direction, so it will not affect the magnetic attraction effect of the second magnetic attraction member 52. Refer to Fig.10 A convex strip 543 is provided on the inner side of the mounting groove 542 , and the convex strip 543 interferes and fixes with the second magnetic attraction member 52 .
[0037] Combination Fig. 9 and Fig.11As shown, the second magnetic member 52 and the mounting groove 542 are arranged in a shape of being larger at the top and smaller at the bottom to prevent the second magnetic member 52 from falling off from the mounting groove 542. In this embodiment, the second magnetic member 52 includes an upper portion 521 and a lower portion 522. In the up-down direction, the projection area of the upper portion 521 is larger than the projection area of the lower portion 522, and the lower portion 522 protrudes downward from the upper portion 521 in a step-like shape. Since the magnet will demagnetize at high temperatures, the platform portion 62 is provided with a vacant groove 66 corresponding to the position of the second magnetic member 52. The projection area of the vacant groove 66 in the up-down direction is larger than the projection area of the second magnetic member 52 in the up-down direction. The second magnetic member 52 and the heat sink 60 are not in direct contact, and the heat will not be directly transferred to the second magnetic member 52, which can effectively prevent the magnet from being demagnetized, and ensure a good assembly effect between the heat dissipation module 200 and the electrical connector 100.
[0038] The above are only preferred embodiments of the present invention, and should not be used to limit the scope of the present invention. That is, any simple equivalent changes and modifications made according to the claims of the present invention and the contents of the present invention specification should still fall within the scope of the present invention patent.
