Problems solved by technology

This connector is specially made for this magnetic head 31, so the price is expensive, which affects the reduction of the overall cost
[0015] In addition, the stem portion 39 not only needs to occupy a large space on the motherboard 38, but also the position of the stem portion 39 on the motherboard 38 is determined by the position of the magnetic head 31. Therefore, it is necessary to make the motherboard 38 small in order to make the device miniaturized. Design freedom is affected when miniaturization

Embodiment Construction

[0054] refer to Figure 1 to Figure 8 The magnetic head of the present invention will be described.

[0055] First, the magnetic head according to the first embodiment of the present invention uses Figure 1 to Figure 8 to explain, figure 1 It is an exploded perspective view. The magnetic head 10 is constituted by a plurality of components housed in a casing 11 .

[0056] The shell 11 is integrally molded with synthetic resin such as polyacetal, and the inner front magnetic core 12, bobbin 13, rear magnetic core 14 and pressing member 15 are packed in order to form a hollow shape.

[0057] The front end surface of the case 11 forms a curved surface corresponding to the medium sliding contact surface formed by the magnetic tape sliding contact surface on the front surface of the front core 12 . Two open slots 17, 17 are formed on the upper surface, and two lead terminals 16, 16 protruding upward from the bobbin 13 can be inserted into the open slots 17, 17 in the same dire...

Abstract

A magnetic head may have: a coil frame (13) wound with a coil (18); a terminal (16) integrally formed with the coil frame (13) and conducting with the coil (18); and connecting the terminal (16) For the lead wire (20) to the outside, form a hole (13a) on the bobbin (13), insert the front end of the terminal (16) into the hole (13a), and connect the connector part (21) arranged at the front end of the lead wire (20) ) is inserted into the hole (13a), so that the connector part (21) and the terminal (16) are fitted. Therefore, the socket on the main board can be omitted, making the connection with the main board cheaper and enabling the miniaturization of the main board.

Description

technical field [0001] The invention relates to a magnetic head, in particular to an electrical connection structure of the magnetic head. Background technique [0002] refer to Figure 16 , Figure 17 A conventional magnetic head as a full erasing head installed in a general VTR device (hereinafter referred to as "device") or the like will be described. [0003] The magnetic head portion 32 of magnetic head 31 is made up of a plurality of components such as front magnetic core, coil frame (not shown in the figure) and the connecting terminal 34 integrated with this coil frame, rear magnetic core (not shown in the figure) etc. of. This multi-part magnetic head portion 32 is fixed in a housing 35 and exposes the ground magnetic tape sliding contact surface 33a of the front magnetic core 33. As shown in FIG. [0004] The bobbin constituting a part of the magnetic head portion 32 is made of a resin material, is formed in a longitudinally long approximately rectangular shape,...
