等の欠点がある。[Detailed description of the invention] The switch mechanism in conventional jacks with a switch, which has a switch mechanism installed in a space provided at the rear of the jack case, is operated by sliding left and right by a spring movement caused by the action of an insertion plug of a movable contact piece of the jack device. It has a configuration in which a switch slider part with a very complicated structure, which has a special shape and has a built-in contactor related to flat plate bending, is fitted into the cavity,
The contact terminal group that is switched by the slider component has a complicated structure in which a separate board is arranged as an insert, and the separate board is fitted as a cover plate for the empty chamber, so the manufacturing and assembly work is expensive and inefficient. Yes, because the switch member is a flat plate processed product and the slot fitting structure of the slider part takes up a lot of space.
It is difficult to miniaturize the switch mechanism, and as a result, it is not possible to provide this type of ultra-compact jack, and
The above-mentioned switch member made of a flat plate product has drawbacks such as a tendency for the spring force to decrease and the long-term stability of the switch action to be unstable.

とを目的とするものである。 The present invention reliably eliminates the above-mentioned conventional drawbacks, and uses all of the switch members of the movable and set contacts as coil spring bodies for bending ultra-fine metal wires, thereby making the switch spring force extremely durable. In addition to stabilizing the switch performance over a long period of time, these spring bodies are attached to the circular axis at two levels, upper and lower, so that the switch acts under the ribbed wall partition. This is an ultra-compact product that can be reduced to a short width, has a simple and compact switch mechanism, and improves assembly efficiency, making it economical and having good switch performance. In addition to making the switch action very soft due to the wire, the movable part and each contact part have rubbing contact due to mutual spring movement, which has a self-cleaning effect on the contact part. The purpose of this is to ensure the elimination of poor contact accidents caused by the formation of oxide films due to long-term use.

A rectangular rib wall 9 of an appropriate width and height is provided in front of the circular axis 8 of the book and is parallel to the rear wall 4 at a distance. On the inner wall surface of the rear wall 4, a semicircular groove 10 into which a wire is fitted with a portion exposed on the circumferential side is provided vertically, and three small holes 11, 12, 13 into which the wire is fitted are provided.

One coil spring contact wire 19 is bent directly upward from the lower end to form an L-shaped contact piece 18 having a sufficient length to protrude above the wall 9. The lower end is bent into a terminal leg piece 21 that passes through the small hole 11 to the outside of the bottom, and the lower end is attached to the wall 9.
springing upwardly toward the longitudinal rear wall 4;
An insulating member 22 is inserted and attached to the tip, and a coil spring movable line 24 is fitted over the upper and lower sides to form a spring movable linear portion 23 of a length that reaches a position where the member 22 is pressed against the front of the insertion plug P. The movable line 2 on the upper side is fitted with a shaft on the stage and equipped with a shaft.
The linear portion 23 of 4 is directed toward the longitudinal rear wall 4, and the insulating member 22 at the tip is in a position where it is pushed by the plug,

できる。 Note that, if necessary, the cover may have a well-known design in which a protruding piece is separately provided at the corner of the case, instead of using the fitting of the circular shaft 8 or the like as described above. Moreover, the form of the contact line 19 that is fitted under the bottom is the L-shaped contact piece 18 shown in the figure.
In addition, as in another example shown in FIG.

行われることになる。 Since the present invention is constructed as described above, by inserting and removing the plug from the insertion hole, the jacking action of moving the movable contact piece 1 and the fixed contact piece 2 toward and away from each other is performed in the jack case portion 3. By entering the front end of the insertion plug P into the rear switch chamber 5, the spring movable linear portion 23 of the coil spring movable line 24 is independent of the movement of the movable contact piece as in conventional products.
As a result, since the straight portion 23 is a coiled wire spring wire, it leaves contact with the other contact wire 26 with a really smooth spring elasticity and connects to the opposite rear one. The coil spring contact wire 19 springs toward the L-shaped contact piece 18 and makes switch contact with the contact piece 18. However, since the contact piece 18 is also made of a coil spring wire, it is pressed by the straight part 23 and springs backwards while remaining in contact, so that a reliable spring contact can be obtained, and insulation is maintained. When the pressure on the member 22 is released, the straight portion 23 is restored by the strong combined spring force of the coil spring and the spring reaction of the contact piece 18 and returns to secure contact with the contact wire 26, and then The spring movement of the movable straight portion 23 on the rib wall 9 ensures a reliable and good switching action without contact failure.

の操作機構は非常に簡素化されることになる。 Therefore, this switch action does not require the installation of complicated slider parts as in the past, and can be performed directly by the coil spring movable line 24 attached to the upper shaft by the plug head.
It is performed by pushing and pushing operation, and also,
As a result, the operation mechanism is greatly simplified as a result of mutual switch operation of the upper and lower coil spring wires mounted on a single axis with an insulator interposed therebetween.

ことになる等の効果がある。 Therefore, the action of the linear portion 23 toward and away from the contact piece 18 is stable, and the so-called self-cleaning action (self-cleaning action) is reliably performed because the contact parts rub against each other every time the switch is operated. As a result, the formation of an oxide film at the mutual contact points is reliably purified and eliminated, and as a result, stable and reliable switch action is guaranteed over a long period of time. In addition to being extremely durable against spring force, unlike flat plates, it can be easily bent, making it suitable for manufacturing ultra-small parts, leading to lower parts costs, and making it possible to bend the coil spring wire up and down with respect to one axis. The two-stage shaft mounting allows the mechanism area to be extremely small, resulting in an ultra-compact switch mechanism that is simple and easy to assemble, and has good switch performance. Since only the molded protrusion 9 is required, the empty chamber 5 can be connected to the case part 3 in series, and the jack case a
Not only is manufacturing very simple, the hollow chamber 5 can be made into an extremely short chamber, and furthermore, the protrusion of the circular shaft 8 allows the height to be adjusted to a height suitable for cover caulking. For example, the shaft head can be passed through the fitting hole 7 of the cover plate 6 to be crimped and fixed, and the cover plate 6 can be attached to the coil spring wire, which also functions as a shaft attachment and crimped fixing, which is very convenient for assembling the device. The case a can be made ultra-miniaturized, and ultra-compact jacks with switches can be mass-produced easily and economically.
In addition, the rib wall 9 on the front side of the circular shaft 8 acts as a stopper for the contact piece 18 of the contact line 19 on the lower side, so together with the coil spring wire pivoting equipment, the assembly work of the switch mechanism is greatly simplified. It has the effect of being simple and efficient.
