DESCRIPTION JPS54108004
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a back view of a head shell. FIG. 2 is a plan
view of the head shell cable of the record player according to the present invention. Fig. 3 shows
a cable for the head shell of a conventional record player. 9 ... end part, 10 ... body part, 11 ...
insulator.
The present invention relates to an improvement of a head shell cable for connecting a cartridge
and a shell shell attached to the front of a tone arm of a record player, and the target k roller has
an electrical conductivity. In addition to being extremely good, it is an object of the present
invention to provide a cable for a head player of a record player which is a production container,
less expensive, and free from fear. Conventional hard shell cable ftl # i, + 11r + -ttpi't- <p1-: "self
indication 1. in FIG. As it is, both terminals fl! Configure the conductor (3) separately from ++ 21,
and further add both terminals +! l(! Since l and lead (3) are soldered (1), there is a problem
in terms of electrical conductivity (electrical conductivity) to use this as a connection between the
head shell and the cartridge and 1-. That is, the voltage of the cartridge attached to the back
surface of the head shell is generally a weak voltage within 0.03 V to 0.3 V, and therefore, the
cable used as the connection part has extremely good electrical conductivity. In the case of the
above conventional example, since the solder 14) is attached, the resistance of the solder (4)
portion is large, so this head shell ## of this ax record player Ineligible for use. Furthermore, it
takes time and labor to attach the solder (4), and there is also a risk that the part attached with
the solder (4) may be detached due to the use for many years even if the solder (4) is once
attached . This invention is a solution to the above-mentioned conventional point, and its
configuration will be described with reference to the drawings shown as one embodiment. (2)-悄

an appropriate number of terminals are formed to protrude at one end. (8) is a cable connecting
between the terminal of the cartridge (6) and the terminal of the connecting portion (7), and is
formed to transmit a weak current to an <cartridge (Ill). That is, as shown in FIG. 2, the cable +

formed of gold, silver, or other suitable material with good electrical conductivity. Insulator (! For

that the two terminals can be brazed inseparably. In the illustrated embodiment, the terminal is
formed to be slightly longer in the lateral direction than the body portion t101 so as to stop the
assembly and be formed so as to be bendable. In the figure (121 is a needle, and it is formed so
as to protrude inward and rearward of the cartridge (6) 1. ている。 Also, (1: 4 is a knob, which is
brazed to the front of the tone arm and which is formed by combining the -side proper position
of the head shell (6) in order to lift and move the 9 shell radium + ll + It is. Next, the usage
condition of the head shell cable of the record player according to the present invention will be
described. First, the both ends 191 + 91 of the cable (8) abut the terminals of the connecting part
(7) and the terminals of the cartridge (6). The both ends +9119+ are bent along the two terminals
so that the cable (8) can not be detached from both the terminals, and attached so as to be
closely fixed to the both terminals. Furthermore, in such a state, the connection part (7) of the
spatula (咄)-"; 7-1 dirty i doshiel 1 lil is connected to all tone arms. Then, the weak current from
the tone arm is transmitted to the end portion (9) of the cable (8) through the terminal 11 of the
connection portion (1), and further, while holding a constant power transmission, the trunk
portion (10) and can be communicated to the terminal of the cartridge (6). The cable for the head
shell of the record player of this invention has the configuration as described above, and the
cable (8) is different from the conventional solder (4) with the cable (1), and a material with good
electrical conductivity. Since it is integrally molded with the cable (1), the electric resistance of
the cable (1) itself that has been brought about by the application of the solder (4) can be
increased! -Prevent 1. Therefore, the cable for the head shell of this type of record player is
provided with extremely good electrical conductivity. obtain. Furthermore, by doing so, the
electrical resistance between the terminals of the connection portion (7) of the head shell (6) (the
terminals of the terminal 61 can be made extremely small, so that a weak current? IIK @ this type
of record player head shell fIIIK used pigeons, very good Il suitable. On the other hand, since the
cable (8) itself is an integral molding structure, it is easy to manufacture, and as a result, if the
material is made of gold or superior and somewhat expensive one, even if C- is mass-produced,
the cost can be reduced. After all, it is possible to provide the market with something worthwhile.
In addition, attach solder (4) 1. Because there is no solder, the negative effects (the risk of
drowning, etc.) arising from the attachment of 41 are completely eliminated! -This tree is
