Company patents

KMW INC.

KMW INC. surprisingly shows a significant, albeit fluctuating, commitment to Antennas, representing 65.3% of its portfolio, with a dramatic 124.1% YoY growth in 2024 followed by declines in 2025 and so far in 2026. While manufacturing-related categories like Mounting Frames & Stands and Fasteners are emerging with 200.0% YoY growth in 2026, the company appears to be shifting away from Electrical Connectors, which saw a 50.0% YoY decline in 2024 and another 50.0% decline so far in 2026.

Cavity filter comprising an elastically deformable terminal portion, where a first side terminal is inserted into a housing of a second side terminal of the terminal portion

Filed:2020-12-11Pub:2024-08-20
Applicant:KMW INC.

The present invention relates to a cavity filter and a connecting structure included therein. The cavity filter includes: an RF signal connecting portion spaced apart, by a predetermined distance, from an outer member having an electrode pad provided on a surface thereof; and a terminal portion configured to electrically connect the electrode pad of the outer member and the RF signal connecting portion so as to absorb assembly tolerance existing at the predetermined distance and to prevent disconnection of the electric flow between the electrode pad and the RF signal connecting portion, wherein the terminal portion includes: first side terminal contacted with the electrode pad; and the second side terminal connected to the RF signal connecting portion, wherein at least any one of the first side terminal and the second side terminal has a housing space in which the other side terminal is housed, and a part of the at least one side terminal is elastically deformed by an assembly force provided by an assembler, and applies lateral tension to the other side terminal while elastically supporting the other side terminal toward the electrode pad. Therefore, the cavity filter can efficiently absorb assembly tolerance which occurs through assembly design, and prevent disconnection of an electric flow, thereby preventing degradation in performance of an antenna device.
