Description

TECHNICAL FIELD

[0001] The present application relates to a shielding cage assembly with a heat dissipation module and an electrical connector thereof. BACKGROUND

[0002] A common challenge faced by developers of electrical systems is heat management. Heat energy generated by electronic devices within the system can reduce the performance of the electronic devices and even damage components of the system, such as electrical connectors. Electrical connectors can be used to transmit data and / or power between different systems or devices. Data signals can be transmitted in the form of optical signals and / or electrical signals through communication cable(s). For example, IC connectors (PGA, etc.), IO connectors (Displayport, VGA, DVI, HDMI, USB, etc.), fiber optic connectors (FC, SC, ST, LC, D4, DIN, MU, MT, etc.), optical communication connectors (SFP, QDFP, etc.), filter connectors, CATV connectors, backplane connectors, memory stick / memory connectors (DDR, SIMM, DIMM, PCI, SIM, etc.), high-definition television connectors (RF coaxial connectors, etc.), flexible circuit board connectors (FPC, FFC, etc.), network cable connectors (RJ45, etc.), audio-video (AV) connectors, battery connectors, and the like. Electrical connectors generate a large amount of heat due to the increasing power.

[0003] To dissipate the heat energy, the system generally includes a thermal component, such as a thermal bridge, which engages a heat source, absorbs heat energy from the heat source, and transfers the heat energy away. However, the existing thermal bridge has a low heat energy transfer efficiency. In addition, due to surface variations, such as surface flatness of the interface, it is difficult to achieve efficient thermal coupling at the interface, which needs to be improved.

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0038] For the accuracy of the description of the present application throughout the description, all the directions are defined as follows: Figure 1 Specifically, the direction along the X axis is defined as the left-right direction (i.e. the width direction of the electrical connector); the direction along the Y axis is defined as the up-down direction, wherein the positive direction of the Y axis is upward; and the direction along the Z axis is defined as the front-rear direction (i.e. the plug-in direction of the mating connector), wherein the positive direction of the Z axis is rearward, i.e. the insertion direction of the mating connector.

[0039] Please refer to Figures 1 to 6 The electrical connector of the present application comprises a metal shell 1, a terminal assembly 5 assembled in the metal shell 1, a first heat dissipation member 2, a second heat dissipation member 3 and a fastener 4 assembled above the metal shell 1. The metal shell 1 comprises a top plate member 11, two side plate members 12 connected to the two sides of the top plate member 11, an end plate member 13 connected to the rear end edges of the top plate member 11 and the two side plate members 12, and a bottom plate member 14 opposite to the top plate member 11 and connected to the two side plate members 12. The top plate member 11, the two side plate members 12, the bottom plate member 14 and the end plate member 13 jointly define a receiving cavity 10 and form an insertion opening 101 at one end. An installation opening 120 is formed between the rear end edge of the bottom plate member 14 and the end plate member 13, and the installation opening 120 communicates the receiving cavity 10 with the outside downward. A through hole 110 is formed in the top plate member 11, and the through hole 110 communicates the receiving cavity 10 with the outside.

[0040] The terminal assembly 5 is provided with an insulating body 51 and a plurality of conductive terminals 52 fixed with the insulating body 51. The terminal assembly 5 is arranged in the receiving cavity 10 of the metal shell 1 by the mounting port 120, specifically at a position close to the rear end of the receiving cavity 10. Wherein, the front end of the insulating body 51 is recessed backward to form a butt joint cavity 510 communicated with the receiving cavity 10, each of the conductive terminals 52 includes a fixed segment (not numbered) embedded and fixed in the insulating body 51, a contact portion 521 extended into the butt joint cavity 510 from the fixed segment, and a butt joint segment (not numbered) extended out of the insulating body 51 from the fixed segment. The butt joint segment is protruded out of the insulating body 51 from the lower surface of the insulating body 51 and used for electrical contact and fixation with the butt joint circuit board 200. In use, the butt joint connector is inserted into the receiving cavity 10 through the insertion port 101 and extended into the butt joint cavity 510 to achieve electrical connection with the contact portion 521 of the conductive terminal 52.

[0041] Please refer to Figures 1 to 5 As shown, the first heat dissipation member 2 is provided with a first main body member 21 and a first protruding portion 22 downwardly extended from the first main body member 21. The edge portion of the first main body member 21 is assembled on the upper surface of the top plate member 11 in a superposed manner. The first protruding portion 22 is protruded into the receiving cavity 10 through the through hole 110. The second heat dissipation member 3 is provided with a second main body member 31 and a second protruding portion 32 downwardly extended from the second main body member 31. The edge portion of the second main body member 31 is assembled on the upper surface of the top plate member 11 in a superposed manner. The second protruding portion 32 is protruded into the receiving cavity 10 through the through hole 110. The first heat dissipation member 2 and the second heat dissipation member 3 are arranged adjacent to each other along the front-rear direction.

[0042] The fastener 4 includes a spring portion 41 and side plate portions 42 extending downwardly from both ends of the spring portion 41. A clamping hole 421 is formed through each side plate portion 42, and an insertion tab 422 is formed by protruding upwardly from the lower edge of the clamping hole 421. A clamping protrusion 121 is formed downwardly from the inner side of the side plate member 12 of the metal shell 1, and protrudes outwardly from the outer surface of the side plate member 12. An insertion opening 122 is formed in the lower end of the clamping protrusion 121. The fastener 4 is arranged astride the first and second heat dissipation members 2 and 3 and is fixed to both sides of the metal shell 1, thereby restricting the first and second heat dissipation members 2 and 3 above the metal shell 1. Specifically, the spring portion 41 is elastically pressed against the first and second heat dissipation members 2 and 3, the side plate portions 42 are arranged in contact with the outer surface of the side plate member 12, the clamping holes 421 are clamped to the clamping protrusions 121, and the insertion tabs 422 are inserted upwardly into the insertion openings 122. This prevents the fastener 4 from being separated upwardly from the metal shell 1. The spring portion 41 can be elastically deformed in the vertical direction, thereby allowing the first and second heat dissipation members 2 and 3 to float within a certain range in the vertical direction relative to the metal shell 1.

[0043] Please refer to Figures 2 to 5 As shown in the drawings, in the present application, the first main body member 21 includes two first side wing portions 211 arranged on both sides of the first protrusion 22, and the two first side wing portions 211 are arranged in contact with the upper surface of the top plate member 11 on both sides of the through hole 110. The second main body member 31 includes two second side wing portions 311 arranged on both sides of the second protrusion 32, and the two second side wing portions 311 are arranged in contact with the upper surface of the top plate member 11 on both sides of the through hole 110. The first main body member 21 further includes a first end wing portion 212 arranged at the front end of the first protrusion 22, and the first end wing portion 212 is arranged in contact with the upper surface of the top plate member 11 at the front end of the through hole 110. The second main body member 31 further includes a second end wing portion 312 arranged at the front end of the second protrusion 32, and the second end wing portion 312 is arranged in contact with the upper surface of the top plate member 11 at the front end of the through hole 110.

[0044] In the present application, the first heat dissipation member 2 and / or the second heat dissipation member 3 can be upwardly floated relative to the metal shell 1. In the preferred embodiment, the first heat dissipation member 2 can be upwardly floated relative to the second heat dissipation member 3, or the second heat dissipation member 3 can be upwardly floated relative to the first heat dissipation member 2. Through the two-piece design of the first heat dissipation member 2 and the second heat dissipation member 3, it is ensured that after the docking connector is inserted into the metal shell 1, the docking connector is in stable contact with the heat dissipation members (the first heat dissipation member 2 and the second heat dissipation member 3) of the electrical connector of the present application. In addition, even if the flatness of the docking surface of the docking connector is not enough, the docking connector can still achieve relatively stable and reliable contact with the heat dissipation members of the electrical connector of the present application. In addition, through the two-piece design of the first heat dissipation member 2 and the second heat dissipation member 3, the normal pressure of the fastener 4 on the docking connector downwardly through the first heat dissipation member 2 and the second heat dissipation member 3 can be reduced to a certain extent.

[0045] In the preferred embodiment of the present application, the end of the first heat dissipation member 2 adjacent to the second heat dissipation member 3 protrudes to form a first boss portion 23 toward the second heat dissipation member 3; the end of the second heat dissipation member 3 adjacent to the first heat dissipation member 2 protrudes to form a second boss portion 33 toward the first heat dissipation member 2. The first boss portion 23 and the second boss portion 33 are stacked in the up-down direction. In the present application, preferably, the lower surface of the first boss portion 22 is coplanar with the lower surface of the second boss portion 32. Preferably, the first boss portion 23 is located below the second boss portion 33, so that after the docking connector lifts up the first heat dissipation member 2, the front end of the second heat dissipation member 3 can be lifted up with the first boss portion 23, preventing the risk of the docking connector hitting the front end of the second boss portion 33 when being inserted.

[0046] Please refer to Figures 1 to 5 In the present application, the lower edges of the two side plate members 12 of the metal shell 1 further extend downwardly to form docking pins 140, which are correspondingly inserted into the insertion holes of the docking circuit board to achieve assembly and fixation. Of course, in other embodiments (as shown in Figure 6 In the present application, the lower edges of the two side plate members 12 of the metal shell 1 further extend downwardly to form docking pins 140, which are correspondingly inserted into the insertion holes of the docking circuit board to achieve assembly and fixation. Of course, in other embodiments (as shown in

[0047] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary and that changes can be made in detail without departing from the principles and spirit of the application. The scope of the application is therefore defined by the appended claims and their equivalents.
