Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an on-off switch and thereby a dual in-line mounting switch device.
[0002]
[Prior art]
A conventional dual-in-line mounting (DIP) switch device usually comprises a plurality of on-off switches 1 arranged in parallel, as shown in FIG. As shown in FIG. 2, these on-off switches 1 each have a base 12 and a lid 13 with an opening 131. The pedestal 12 has two upper and lower surfaces, and a bottomed hole 121 is formed on the upper surface thereof. When the lid 13 with the opening 131 is coupled to the pedestal 12 from above, the storage space that shields the bottomed opening 121 and communicates with the bottomed opening 121 between the bottomed opening 121 and the pedestal 12. 132 is formed.
On both sides opposite to the lower surface of the pedestal 12, copper elastic connection pins 14 and 15 penetrating from the outside of the pedestal 12 into the pedestal 12 are provided. The two copper elastic connection pins 14 and 15 are arranged so that one end sides 141 and 151 are substantially juxtaposed outside the pedestal 12 as terminals, and the other end sides 142 and 152 are substantially horizontally in the bottomed opening 121. After extending from the opposing direction, they are in contact with each other to form an on state.
[0003]
A lever 16 is pivotally connected to the storage space 132 of the lid 13 so as to be rotatable. The lever 16 has a protrusion 161 formed above the other end 152 of the copper elastic connection pin 15, and a part 162 of the protrusion 16 is exposed to the outside of the lid 13 from the opening 131 of the lid 13. ing.
[0004]
Accordingly, as shown in FIG. 3, when the lever 16 is actuated and moved downward, the protrusion 161 of the lever 16 resists the elasticity of the elastic connection pin 15, while the elastic connection pin 15. When the other end 152 is pressed, the other end 152 is separated from the other end 142 of the elastic connecting pin 14 by a predetermined gap to be turned off, and is actuated again to move upward, as shown in FIG. As shown, it can be returned to the on state.
[0005]
[Problems to be solved by the invention]
Such an on-off switch 1 has an on / off function, but the elastic connection pin 15 is made of a copper material having a low breaking strength and is made from the lever 16 on the other end side 152. The place where the power is received is almost straight and the bending strength is not so good, so elastic fatigue tends to occur, so if it is repeatedly switched on and off, the elastic return force disappears and it can not be switched well Become. That is, the conventional on-off switch 1 has a drawback that its service life is short.
[0006]
In view of the above, an object of the present invention is to provide an on-off switch and a dual in-line mounting switch device by which an elastic fatigue hardly occurs and the service life is longer than that of the conventional one.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention first comprises a pedestal having two upper and lower surfaces and a bottomed opening formed on the upper surface thereof, shielding the bottomed opening, and the pedestal. A lid with an opening coupled to the pedestal from above so as to form a storage space communicating with the bottomed opening between the first metal connection pin and the second, downward from the lower surface of the pedestal The first and second metal connection pins are not in contact with each other so that the metal connection pins of the first and second metal connection pins are protruded so as to be substantially juxtaposed and an off-contact is formed in the bottomed opening. It consists of an off-contact set extending through the base and extending into the bottomed opening, and a curved elastic metal piece protruding upward, one end of which is a first metal connection in the bottomed opening Always in contact with the pin, the other end is a gap with the second metal connection pin in the bottomed opening The contactor installed between the off contact set and the lid body so as to be opened and always separated, and the contactor from above is contacted from above, and a part of the contactor is outside the lid body from the opening of the lid body. A lever that is pivotally supported in the storage space of the lid so as to be exposed, and when the lever is operated, the contactor is pressed against its elasticity, The other end is brought into contact with the second metal connecting pin in the bottomed opening to turn on the off contact set, and when operated again, the off contact set is returned to off. An on-off switch is provided that is configured.
[0008]
The on-off switch having the above-described configuration turns on and off the off-contact set through a curved contactor. Therefore, any one of the first and second metal connection pins constituting the contact set at the upper end portion thereof. Since it does not receive the actuating force from the lever, it does not cause breakage or elastic fatigue, and the contactor that receives the actuating force from the lever is curved, so the bending strength is far greater than the conventional straight shape. In addition, one end as a swing fulcrum of the contactor is not a fixed type and is supported by being always in contact with the first metal connecting pin in a floating manner. The bending moment can be eliminated loosely, that is, the on-off switch according to the above configuration is less likely to cause elastic fatigue in terms of the configuration. There is an advantage that the service life is much longer.
[0009]
A mounting plate extends from the vicinity of the other end of the contactor itself, whereby the contactor can be fixed to the pedestal by the mounting plate. The whole contactor in which the mounting plate is extended is hereinafter referred to as a contactor element. The mounting plate may be connected to the contactor by a welding method, or may be formed integrally with the contactor. When the contactor and the mounting plate are formed by press-molding a flat and long flat metal plate material, the contactor and the mounting plate are respectively one end side and the other of the flat and long metal plate material. A mounting hole is formed near the free edge of the mounting plate formed on the end side and is fixed to the pedestal near the free end of the mounting plate formed on the other end side. It is preferable that the other end of the contactor formed on the metal plate is partly punched downward from the surface of the metal plate so as to form a hole. Then, not only can the material cost be saved when molding the contactor element, but the hole is formed in advance in the metal plate material, and the localization of the molding machine in the subsequent molding process can be easily and accurately performed. In addition, when the on-off switch is assembled, the contactor element is locked to the pedestal by the mounting hole formed in the mounting plate, and the contactor element is easily fixed at the exact position of the pedestal. Therefore, the yield can be improved and the cost can be further reduced.
[0010]
The contactor is preferably formed of a TiCu alloy material that has a good elastic restoring force and is less susceptible to elastic fatigue.
[0011]
The present invention can further provide a dual in-line mounting (DIP) switch device in which a plurality of the on-off switches are arranged in parallel based on the structure of the on-off switch.
[0012]

And when the lid 6 and the pedestal 5 are coupled as described above, the lid 6 shields the plurality of bottomed holes 52, and the A plurality of storage spaces 62 communicating with the corresponding bottomed holes 52 are formed between the lid 6 and the base 5. In addition, a concave groove 63 is formed in each of the opening edges of the plurality of openings 61.
[0015]
Then, near the bottom surfaces of the plurality of bottomed openings 52 of the pedestal 5, off contact sets 7 are respectively provided. The off contact set 7 includes a first metal connection pin 71 and a second metal connection pin 72. More specifically, the first metal connection pin 71 and the second metal connection pin 72 protrude so that the lower end portions 711 and 721 thereof are substantially juxtaposed downward from the lower surface of the base 5 as terminals, and In order to form an off-contact in the bottomed opening 52, the upper ends 712 and 722 penetrate through the pedestal 5 so as to face each other almost horizontally from opposite sides of the pedestal 5 without contacting each other. Then, it extends into the bottomed opening 52.
[0016]
Between the plurality of off contact sets 7 and the lid body 6, contactor elements 8 each formed by forming a flat and long TiCu alloy plate material by, for example, press working are installed. The contactor element 8 includes a contactor 81 formed on one end side of the long TiCu alloy plate material and a mounting plate 82 formed on the other end side. The contactor 81 has a curved shape in which an intermediate portion projects upward and the two ends 811 and 812 are extended obliquely downward. The two ends of the contactor 81 are one end 811 as a free end, and a hole 821 is formed in the surface of the elongated TiCu alloy plate material, and the mounting plate 82 is extended just before the hole 821 so that the mounting plate 82 is extended downward from the surface. And the other end 812 formed by punching out the portion. An attachment hole 822 for fixing to the attachment projection 55 of the pedestal 5 is formed near the free end of the attachment plate 82. That is, the mounting plate 82 has a hole 821 that can easily and accurately position the molding tool in the subsequent molding process from the contactor 81 to the free edge, and the mounting plate 82 for the mounting of the pedestal 5. An attachment hole 822 for engaging with the protrusion 55 is formed. In the contactor element 8, one end 811 of the contactor 81 is always in contact with the first metal connection pin 71 in the bottomed opening 52 and the other end 812 is in the bottomed opening 52 through the mounting hole 822. The second metal connection pin 72 is fixed to the mounting protrusion 55 of the base 5 so as to be always spaced apart from the second metal connection pin 72.
[0017]
In addition, in each of the plurality of storage spaces 62 of the lid body 6, the levers 9 are pivotally supported. The lever 9 is in contact with the intermediate portion of the contactor 81 from above, and a part 91 of the lever 9 is exposed to the outside of the lid body 6 from the opening 61 of the lid body 6. Further, a protrusion 92 is formed at a position corresponding to the concave groove 63 of the lid 6 of the lever 9.
[0018]
Accordingly, when the lever 9 is actuated and moved downward, as shown in FIG. 6, the lever 9 is pressed against the elasticity of the contactor 81 to open the other end 812 of the contactor 81. The off contact set 7 can be turned on by contacting the second metal connection pin 72 in the hole 52. At that time, the lever 9 can be locked by the structural relationship between the protrusion 92 and the concave groove 63 of the lid body 6, so that the off contact set 7 can be held in an on state. Then, as shown in FIG. 5, when the lever 9 is actuated again to release the locking between the projection 92 and the concave groove 63 of the lid body 6, The off contact set 7 can be returned to the off state.
[0019]
The contactor element 8 in the on-off switch of the present invention and the dual in-line mounting switch device according to the present invention is not only made of a TiCu alloy material having good elastic restoring force and relatively less likely to cause elastic fatigue. However, since it is stronger than before, the service life is considerably long. Further, since the hole 821 can be formed in advance when the contactor element 8 is molded, the positioning of the molding tool can be easily and accurately performed in the subsequent molding process, and the on- When the off switch is assembled, the contactor element 8 is moved to the exact position of the pedestal 5 by the engagement between the mounting hole 822 formed in the mounting plate 82 of the contactor element 8 and the mounting projection 55 of the pedestal 5. Therefore, the yield can be improved and the cost can be further reduced.
