[0035] The connecting lug 1 is a structure for connecting the watch band, and usually has a connecting hole or a connecting structure for installing a hand-pulled spring bar 10 or a push-pulled spring bar 11, so as to realize the connection of the watch band. The connecting lug 1 is a plastic part. Since plastic does not interfere with the signal of the antenna, using a plastic-made lug arranged on the lug assembly can solve the problem of antenna clearance.

[0036] In the main body of the wrist-worn device provided by the present application, an antenna structure is formed by the antenna trace of the housing and the metal-structured lug assembly, so as to realize the signal transmission and reception functions of the communication device inside the housing.
