Description

[Detailed description of the invention] [Industrial field of application] The invention is based on the following:
The present invention relates to a composite electronic component in which each operating shaft of a plurality of variable resistor bodies and each push button of a plurality of push button switch bodies are arranged.

[Summary of the invention] The present invention is provided with a vertical casing that houses a plurality of variable resistor bodies and a plurality of push button switch bodies, and a common plate surface of the vertical casing has a plurality of variable resistor bodies. The operating shafts of the push button switches are arranged vertically in multiple stages in a staggered manner, and on the common plate surface of the vertical casing, a plurality of push buttons of each push button switch body are arranged along each row of the staggered arrangement of the operating shafts. The push buttons are arranged in a staggered manner between the operating shafts, and the height of each push button is lower than each operating shaft so as not to interfere with the operation of each operating shaft. An auxiliary arm is provided to prevent tilting, a protrusion is provided on the lower surface of the auxiliary arm for insertion into the circuit board, and a hook piece is provided at the lower front side of the vertical casing for locking to the circuit board. A terminal of each of the variable resistor bodies and a terminal of each of the push button switch bodies are protruded from the lower part of the vertical casing and are positioned between the hook piece and the protrusion.

[Prior Art] This type of conventional composite electronic component has the operating shafts of a plurality of variable resistor bodies and the push buttons of a plurality of push button switch bodies arranged in a horizontal row on a common plate surface of a vertically oriented casing. The structure was such that an auxiliary arm was provided on the back side of the plate surface of the vertical casing to prevent the vertical casing from tilting.

[Problems to be Solved by the Invention] However, with this structure, there is a problem in that when the number of operating shafts and push buttons is increased, the lateral dimension of the vertical casing increases.

In an attempt to improve this, it may be possible to arrange the operating shaft and push buttons in multiple stages above and below the vertical casing, but if you do this with the conventional structure, even if the auxiliary arm to prevent tilting is on the back side, As the number of stages of the operating shaft and push buttons in the vertical direction increases, the rotational moment when the topmost push button is pressed increases, and as a result, the front part of the vertical casing lifts up using the auxiliary arm as a fulcrum. This poses a problem in that the force required to do so is large, and that there is a high risk of poor contact occurring due to peeling of the soldered portion on the terminal side after several operations.

In addition, if multiple push buttons are concentrated at one location in the longitudinal direction of the vertical casing, a large pressing force from each push button will act only on that location, so the same applies to that side as described above. There was a problem in that the force trying to lift up the front part of the vertically oriented casing was large, increasing the risk of a contact failure due to peeling or the like at the soldered part of the terminal on that side.

The purpose of the present invention is to prevent an increase in the horizontal dimension of the vertically oriented casing even if the number of operating shafts and push buttons thereof is increased, and to prevent peeling off at the soldered part of the terminal when operating the operating shaft or push buttons. The object of the present invention is to provide a composite electronic component that can prevent the occurrence of poor contact accidents.

[Means for solving the problems] The structure of the present invention to achieve the above purpose is as follows:
Referring to FIGS. 1 and 2, which correspond to embodiments, the composite electronic component of the present invention includes a vertical casing 1 containing a plurality of variable resistor bodies and a plurality of push button switch bodies; A plurality of operating shafts 3 of the variable resistor main bodies are arranged vertically in multiple stages in a staggered manner through a common plate surface 2 of the vertically oriented casing 1, and the common plate surface 2 of the vertically oriented casing 1. A plurality of push buttons 4 of each of the push button switch bodies are arranged in a staggered manner between the operating shafts 3 along each row of the staggered arrangement of the operating shafts 3, and the height of each of the push buttons 4 is set according to the height of each of the operating shafts. An auxiliary arm 1a is provided on the back side of the vertical casing 1, which is lower than each of the operating shafts 3 so as not to interfere with the operation of the shaft 3, and prevents the vertical casing 1 from tilting. A projection 1b for insertion into a circuit board is provided on the lower surface of the vertical casing 1, and a hook piece 6 for engaging the circuit board is provided at the lower front side of the vertical casing 1. The terminal 5 of each variable resistor main body and the terminal 5 of each push button switch main body are provided protrudingly provided between the hook piece 6 and the protrusion 16 at the lower part.

[Operation of the invention] In this way, the plurality of operating shafts 3 of each variable resistor main body
are arranged vertically in multiple stages in a staggered manner, and a plurality of push buttons 4 of each push button switch body are arranged on a common plate surface of the vertical casing 1 along each row of each operation shaft 3 arranged in a staggered manner. If the push buttons 4 are arranged in a staggered manner between the operating shafts 3, and the height of each push button 4 is lower than each operating shaft 3 so as not to interfere with the operation of each operating shaft 3, the operability of each operating shaft 3 will deteriorate. Don't let me,
It is possible to prevent an increase in the horizontal dimension of the vertically oriented casing 1, and to reduce the mounting area on the circuit board on which the component is mounted even if it is a composite electronic component equipped with a plurality of variable resistor bodies and a plurality of push button switch bodies. can do.

Furthermore, even if the operating shafts 3 and push buttons 4 are arranged in multiple stages vertically, the auxiliary arm 1a on the back side of the vertical casing 1 prevents the vertical casing 1 from tilting when operating the operating shaft 3 or the push buttons 4. To prevent.

Further, the hook piece 6 prevents the vertical casing 1 from lifting up when the operating shaft 3 or the push button 4 is operated.

In particular, since the push button 4 exerts a strong force to press the vertical casing 1 to the back side when it is operated, the auxiliary arm 1a has a great effect of preventing tilting, and the hook piece 6 has a great effect of preventing floating.

In addition, since the push buttons 4 are arranged in a dispersed manner in the horizontal direction of the vertical casing 1, it is possible to avoid pressing only a part of the vertical casing 1 in the horizontal direction. It is possible to prevent the occurrence of poor contact accidents due to peeling at the attachment part.

In addition, since each terminal 5 is provided between the hook piece 6 and the protrusion 1b, when the vertical casing 1 is lifted up, the force applied to the soldered portion of each terminal 5 is prevented by the hook piece 6 and the protrusion 1b. Protect with.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 and 2.

In the composite electronic component of this embodiment, a plurality of variable resistor bodies and a plurality of push button switch bodies (not shown) are housed in a vertical casing 1 in a staggered manner under the conditions described below. Correspondingly, on the common plate surface 2 of the vertical casing 1, the operation shafts 3 of the respective variable resistor bodies are arranged in two stages, upper and lower, in a staggered manner. Further, on the common plate surface 2 of the vertical casing 1, the push buttons 4 of the push button switch bodies are arranged in a staggered manner along each row of the operating shafts 3 and between the operating shafts 3. ing. For this reason, the push buttons 4 are arranged in a dispersed manner in the lateral direction of the vertical casing 1. The height of each push button 4 is set so that it does not interfere with the operation of each operation axis 3.
is set lower.

On the back side of the plate surface 2 of the vertical casing 1, there is an auxiliary arm 1 that prevents the vertical casing 1 from tilting.
A is provided. The lower surface of the auxiliary arm 1a is perpendicular to the lower end of the plate surface 2, and a protrusion 1b is provided on the lower surface of the auxiliary arm 1a for insertion into a circuit board (not shown) serving as a support. .

At the center of the lower part of the vertical casing 1 and at both left and right ends, hook pieces 6 for attachment to a circuit board, which is a support, are integrally molded and protruded.

Further, on the lower surface of the vertical casing 1, terminals 5 of each variable resistor body and each push button switch body are provided protrudingly. These terminals 5 especially have hook pieces 6.
and the protrusion 1b.

Such a composite electronic component has an auxiliary arm 1a provided on the back side of the vertical casing 1 to provide support (not shown) even if the operating shafts 3 and push buttons 4 are arranged in multiple stages vertically in the vertical casing 1. Since the vertical casing 1 is supported against the circuit board which is the body, the vertical casing 1 is prevented from tilting when the operation shaft 3 or the push button 4 is operated.

In addition, since each hook piece 6 is locked to a circuit board (not shown) at this time, the operating shaft 3 or push button 4
When an operating force is applied to the vertical casing 1, the vertical casing 1 lifts up from the support, and it is possible to prevent contact failures caused by peeling of the soldered portions of the terminals 5, etc.

In particular, when the hook piece 6 is integrally formed on the vertical casing 1, the positioning accuracy is improved and the elasticity of the hook piece 6 is improved.

Furthermore, since each terminal 5 is provided between the hook piece 6 and the protrusion 1b, when the vertical casing 1 is lifted up, the force applied to the soldered part of each terminal 5 is prevented by the hook piece 6 and the protrusion 1b. to ensure protection.

In addition, since the push buttons 4 are arranged in a distributed manner in the horizontal direction of the vertical casing 1, it is possible to avoid pressing only a part of the vertical casing 1 in the horizontal direction, and in this aspect as well, the It is possible to prevent the occurrence of poor contact accidents due to peeling or the like at the soldered part 5.

In particular, since the push button 4 exerts a strong force to press the vertical casing 1 to the back side when it is operated, the auxiliary arm 1a has a great effect of preventing tilting, and the hook piece 6 has a great effect of preventing floating.

Furthermore, when the operating axes 3 are arranged in a staggered manner, the arrangement is similar to that in which the operating axes 3 are arranged every other one compared to the conventional arrangement, and there is more space around each operating axle 3. . Therefore, even if the device is downsized, the operability of each operating shaft 3 is not impaired.

Furthermore, if the push buttons 4 are arranged in a staggered manner between the operating axes 3 in the rows of the operating axes 3 arranged in a staggered manner, the degree of integration can be increased and miniaturization can be achieved.

Moreover, even with the increased integration and miniaturization, the height of each push button 4 is lower than each operating shaft 3, so it does not interfere with the operation of each operating shaft 3.
Moreover, since each push button 4 is operated by simply pressing it, it does not interfere with the operation.

[Effects of the Invention] As explained above, according to the composite electronic component according to the present invention, the following effects can be obtained.

(a) A plurality of operating shafts of each variable resistor body are arranged vertically in multiple stages in a staggered manner, and a plurality of push buttons of each push button switch body are arranged on a common plate surface of the vertical casing. Since the operating shafts are arranged in a staggered manner along each row and between the operating shafts, it is possible to prevent an increase in the horizontal dimension of the vertically oriented casing, and it is possible to prevent a plurality of variable resistor bodies and a plurality of push button switch bodies from increasing. Even if a composite electronic component is mounted, the mounting area on the circuit board to which it is mounted can be reduced.

(b) Even if the composite electronic components are made to have a high density in this way, the height of each push button is lower than the height of each operating axis, so the operability of each operating axis will not be impaired, and each push button can be pressed only by pressing it. Operability is not impaired either.

(C) Even if the operating shafts and push buttons are arranged in multiple stages above and below on a vertical casing, an auxiliary arm is provided on the back side of the vertical casing, and the vertical casing can be held against the circuit board that is its support. Since the vertical casing is supported, it is possible to hold the vertical casing so that it does not tilt when operating the operating shaft or push button.

(d) Also, since each hook piece is locked to the circuit board at this time, when operating force is applied from the operating shaft or push button, the vertical casing will lift off from the support, causing peeling at the soldered part of the terminal, etc. It is possible to prevent the occurrence of poor contact accidents.

(E) Since each terminal is provided between a hook piece and a protrusion, these hook pieces and protrusions must reliably protect the soldered portion of each terminal from the force applied when the vertical casing lifts up. Can be done.

(F) Since each push button is arranged in a distributed manner in the horizontal direction of the vertical casing, it is possible to avoid pressing only a part of the vertical casing in the horizontal direction. It is possible to prevent the occurrence of poor contact accidents due to peeling or the like at the attachment part.

(G) In particular, since the push button has a strong force pressing the vertical casing against the back side when it is operated, the auxiliary arm has a great effect of preventing inclination, and the hook piece has a great effect of preventing lifting.
