Abstract: An anti-loosening washer (100) for a threaded connector (200) and a fabrication method thereof are provided. The anti-loosening washer (100) includes an upper washer (1) and a lower washer (2). A plurality of first ratchet teeth (3) distributed in a fan shape are disposed at the bottom of the upper washer (1), and a plurality of second ratchet teeth (4) engaged with the first ratchet teeth (3) are disposed on the top of the lower washer (2). The first ratchet tooth (3) has a wide surface (31) attached to the second ratchet tooth (4) and a narrow surface (32) with an area less than an area of the wide surface (31). The wide surface (31) is a spiral surface formed through a spiral motion performed by a generatrix (12) spaced apart from an axis (11a) around the axis (11a) by using a central axis (11) of the upper washer (1) as the axis (11a). A lead angle of a wire (13) at a middle diameter position of the spiral surface is greater than a lead angle of the threaded connector (200).

Abstract: The present invention discloses a low-dielectric resin composition, a low-dielectric resin/metal composite material and a preparation method thereof, and an electronic device. The resin composition comprises, based on 100% by weight of the resin composition: 45-70 wt% of a base resin, 20-45 wt% of a chopped glass fiber, 1-3 wt% of a toughening resin, 0.2-0.5 wt% of an unmodified glycidyl methacrylate, and 0-10 wt% of an auxiliary. The base resin is selected from the PBT resin and/or the PPS resin. The chopped glass fiber has a dielectric constant of 4.0 to 4.4 at 1 MHz. With the same base resin component, the dielectric constant and dielectric loss of the low-dielectric resin material prepared with the low-dielectric resin composition are significantly reduced, which is advantageous for satisfying the requirements of use of plastics for antenna channels in metal shell of an electronic device, so as to improve the ability of the electronic device having antennas to receive and transmit signals.
