The invention relates to a connector and a shell assembly thereof. The shell assembly of the connector comprises an insulator. The insulator is provided with a contact piece installation cavity. A metal heat conducting layer is fixed on the inner wall and / or the periphery of the insulator. The insulator is provided with insulator heat dissipation holes on the side wall of the contact piece installation cavity, wherein the insulator heat dissipation holes are communicated with the contact piece installation cavity and the outer peripheral surface of the insulator. Heat conducting layer heat dissipation holes are formed in the metal heat conducting layer. The heat conducting layer heat dissipation holes are communicated with the insulator heat dissipation holes to form heat dissipation channels for heat dissipation. On one hand, the metal heat conduction layer can form a heat dissipation channel between the interior of the insulator and outside air, so the heat is freely dissipated, heatconduction can be performed on the dissipated heat through the metal heat conduction layer, heat is conducted and dissipated through the high heat conduction performance of metal, restraining of temperature rise of the contact piece is achieved through the composite heat dissipation effect of the heat dissipation channel and the metal heat conduction layer, heat dissipation of the connector is accelerated, the effect is remarkable, and the structure is simple.
Description
technical field [0001] The invention relates to a connector and its shell assembly. Background technique [0002] Existing high-current connectors include an insulator and a metal shell fixed outside the insulator. At the same time, the insulator is equipped with contacts. With the improvement of the connector's flow capacity, the heat generated by the electronic components is increased, so that the contact The temperature rise of the contact piece increases, and the temperature rise is a key factor affecting the performance of the high-current connector. The problem of the temperature rise of the contact piece in the prior art is generally to make the contact resistance of the contact piece as small as possible, that is, generally adopt Changing tin bronze to high-conductivity copper, high-conductivity copper has high conductivity and fast heat dissipation, which can reduce the contact resistance of contacts, thereby reducing heat generation. However, with the further impro...
