Description

Cover assembly for connector and connector

Technical Field

The application relates to a cover assembly for a connector and the connector.

Background

In electronic devices, it is generally desirable to transfer thermal energy (or heat) away from designated components of the system or device. For example, electrical connectors may be used to transfer data and/or power to each other between different systems or devices. The data signals may be transmitted in the form of optical signals and/or electrical signals over the communication cable(s). Such as IC connectors (PGA, etc.), IO connectors (Displayport, VGA, DVI, HDMI, USB, etc.), fiber optic connectors (FC, SC, ST, LC, D, DIN, MU, MT, etc.), optical communication connections (SFP, QDFP, etc.), filter connectors, CATV connectors, backplane connectors, memory stick/memory connectors (DDR, SIMM, DIMM, PCI, SIM, etc.), high definition television connectors (radio frequency coaxial connectors, etc.), flexible circuit board connectors (FPC, FFC, etc.), cable connectors (RJ 45, etc.), audio Video (AV) connectors, battery connectors, etc.

A common challenge facing developers of electrical systems is thermal management. The thermal energy generated by the electronics within the system can degrade the performance of the electronics and even damage components of the system. To dissipate heat energy, the system generally includes a thermal component, such as a thermal bridge, that engages the heat source, absorbs heat energy from the heat source, and transfers the heat energy away. However, the heat energy transfer efficiency of the existing heat bridge is low. In addition, it is difficult to achieve efficient thermal coupling at the interface due to variations in the surface, for example, due to surface flatness of the interface surface, etc.

Accordingly, there is a need for a heat transfer assembly that transfers thermal energy away from components (e.g., the internal electronics of an electrical connector) and has a thermal resistance that is effective to reduce.

The second end fixing frame is respectively bent at the two ends in the left-right direction to form bending parts, and the bending parts extend in the front-back direction and are buckled at the two sides of the heat dissipation assembly. Similar effects can be achieved as well. In this embodiment, the first end fixing frame and the second end fixing frame may be directly welded to the top plate 41 (it is naturally necessary to design the first end fixing frame and the second end fixing frame to be attached to the top plate 41).

Referring to fig. 9 and 10, in another embodiment of the cover assembly for the connector of the present application, the top plate 41 'of the metal shell 4' is not provided with the opening 402 in the embodiment shown in fig. 3. The lower surface of the lower heat dissipation assembly 2' is directly attached to and welded to the upper surface of the top plate 41', and the lower heat dissipation assembly 2' is not provided with the protruding structure 211 as in the embodiment shown in fig. 4. When the butt connector is inserted into the functional space, the butt connector is directly contacted with the spring plate structure of the spring plate assembly 6 for heat transfer, and then the heat is transferred to the lower heat dissipation assembly 2 'through the top plate 41'. Of course, in other embodiments, the spring element 6 may not be provided.
