Embodiment Construction

[0023] A motor for a rotary drum device according to an embodiment of the present invention will be described with reference to the drawings. Such as figure 1 As shown, the motor 10 for the rotary drum device consists of a rotor shell 12 that is arranged on the rotary drum 3 of the rotary drum device, a rotor 11 that alternately has a plurality of N, S magnetic pole magnets 13 and a rear bracket 14 and The stator 15 provided on the fixed drum 4 is constituted.

[0024] The stator 15 of the motor 10 for the rotary drum unit, such as figure 2 As shown, a flexible printed wiring board (FPC) consisting of a flexible printed coil (FP coil) 20 with a two-layer structure and a rotation control (FG, PG) part (not shown) connected to the FP coil 20 30 poses.

[0025] The FP coil 20 with a 2-layer structure is composed of an insulating layer + patterned copper foil + coil base material + patterned copper foil + insulating layer (not shown in the figure). The patterned copper foil pa...

Abstract

To solder an FP coil and an FP wiring board so that solder fusing and flowing at soldering is not connected to other patterns. In the case of soldering the solder-plated terminal 25 of the FP coil 20 used as a stator in a motor for a rotary drum device or the like and the solder-plated wiring 35 of the FP wiring board 30 connected to the FP coil 20, the terminal 25 of the FP coil 20 is formed with a plurality of slits S having escape ways for air, and the connection between the FP coil 20 and the FP wiring board 30 is heated and pressurized for soldering. Fusing and flowing surplus solder is settled in the slits S and does not contact with adjacent patterns.

Description

technical field [0001] The present invention relates to a connection method of an FP coil and an FP wiring board and a motor using the FP coil. Background technique [0002] The rotating drum of the AV cam encoder is the part that records the recording signal on the magnetic tape and drives the magnetic head with the function of reproducing the recorded signal, such as figure 1 As shown, the rotating magnetic drum 3 installed on the upper part of the fixed shaft 1 via the bearing 2, the fixed magnetic drum 4 arranged on the lower side of the rotating magnetic drum 3, the magnetic head (not shown) installed on the rotating magnetic drum 3 Figure), the motor 10 that drives the rotary magnetic drum 3, etc. constitutes. [0003] In order to record / reproduce AV signals with a wide frequency range, the rotation of the magnetic head and the running of the magnetic tape need to be controlled quickly and precisely, which is required in the mechanism part, the accuracy of the magneti...
