The invention relates to the technical field of metal material processing, in particular to a method for manufacturing a copper-aluminum combined 5G antenna radiator, which is made by die-casting a copper sheet that has been frosted in advance. This method can connect copper and aluminum The thermal resistance is minimized. At the same time, due to the semi-ellipsoidal sheet structure of the heat sink, the heat dissipation speed can be accelerated. In addition, the use of pure copper as the substrate can even out the heat of the chip, and at the same time better The heat is transferred to the aluminum fins, the temperature distribution of the radiator is even, and the surface temperature difference is small. Multiple heat sinks work at the same time, and the heat dissipation efficiency is high. Due to the arc-shaped structure inside, it can strengthen the rise of the weak airflow, and enhance the convection efficiency of the fins and air.

A rotatable grip for cameras consists, according to the invention, of a play-free latching mechanism comprising, arranged one after the other, a bearing ring (2), a grip plate (3), a leaf spring (4) and steel balls (5) deposited therein with a form fit. According to the invention, leaf spring (4) and bearing ring (2) are connected to the base body of the camera by the balls being pushed into the holes (8) of the grip plate (3) by the leaf spring (4). The connection is preferably effected with the aid of a screw-connection (6). Due to the rotation of the grip (1), the balls (5) are pushed out of the hole of the grip plate (3) counter to the spring force. The grip (1) is pivoted until the balls (5) latch in the desired position into the holes of the selected latch position. In order to secure the selected latch position in the long term, a blocking plate (7) which can pivot about the axis of rotation of the grip plate (3) can prevent the latch balls (5) from moving.
