Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a switch structure that is applied to electrical equipment, and more particularly to a switch structure that turns on and off a power feeding path using a fixed terminal and a movable terminal that is in contact with and away from the terminal. The switch structure is applied to electric devices such as a face shaver, an electric toothbrush, an electric nail polisher, and a shaver.
[0002]
[Prior art]
With respect to the present invention, an electric shaver disclosed in JP-A-10-235037 is known. There, a slider and an operation knob are arranged inside and outside the case body, and both are engaged and connected by an engaging claw so as to be slidable together. The slider simultaneously contacts the positive terminal on the positive electrode side and the fixed terminal on the negative electrode side provided in the case, and conducts both the fixed terminals.
[0003]
[Problems to be solved by the invention]
In the electrical equipment as described above, the fixed terminal is simply press-fitted to the case, or a part of the fixed terminal is welded and fixed to the case, eliminating the need for assembly or simplifying the fixing structure of the fixed terminal. It has become. However, since the fixing strength of each terminal with respect to the case is not always sufficient, there is room for each terminal to move with respect to the case or to float away from the inner surface of the case. Furthermore, the fixed terminal and the movable terminal formed of a metal thin plate do not have sufficient strength per se, for example, may be plastically deformed due to a drop impact, or may be lifted away from the case. Poor contact may occur between both terminals. In particular, in a small electric device, it is necessary to reduce the size of the entire device, and both terminals tend to be extremely small, and contact failure based on the above-described deformation and displacement tends to occur.
[0004]
An object of the present invention is to improve a switch structure including a fixed terminal and a movable terminal, for example, even when receiving a drop impact, poor contact due to misalignment of the fixed terminal, separation from the case, etc. It is to reliably prevent the switching structure and improve the reliability of the switch structure.
[0005]
[Means for Solving the Problems]
In the switch structure of the present invention, a fixed terminal 25 and a movable terminal 24 that contacts and separates from the fixed terminal 25 are provided in the case body 1. A switch piece 23 that supports the movable terminal 24 and an operation knob 6 that slides the switch piece 23 are disposed inside and outside the case body 1. The switch piece 23 is provided with a pressing portion 39 that extends toward the fixed terminal 25 beyond the contact / separation piece 37 of the movable terminal 24. When the operation knob 6 is turned on, the contact / separation piece 37 is in contact with the fixed terminal 25 while the pressing portion 39 presses and holds the switch portion 25a of the fixed terminal 25 in an appropriate posture.
[0006]
The switch portion 25 a of the fixed terminal 25 is arranged in a direction that intersects the sliding direction of the movable terminal 24. The left and right sides of the intersection of the switch portion 25a with the slide locus of the movable terminal 24 are fixedly held on the inner surface of the case body 1.
[0007]
In the off state where the movable terminal 24 is separated from the fixed terminal 25, the switch portion 25 a of the fixed terminal 25 is pressed and held by the pressing portion 39 of the switch piece 23.
[0008]
The contact / separation piece 37 of the movable terminal 24 is arranged in a space formed by hollowing out the pressing portion 39 of the switch piece 23.
[0009]
The switch piece 23 is slidably guided by the case body 1 and the peripheral surface 4 a of the motor 4 accommodated in the case body 1. The inner surface facing the peripheral surface 4a of the motor 4 of the pressing portion 39 of the switch piece 23 in the off state is pressed and held by the flat peripheral surface 4a.
[0010]
The case body 1 is provided with an inner receiving wall 48 that receives the inner surface of the upper end of the pressing portion 39 of the switch piece 23 from the inward side when the movable terminal 24 is in an off state in which the movable terminal 24 is separated from the fixed terminal 25.
[0011]
A passive piece 41 is provided at the protruding end of the switch piece 23 on the pressing portion 39 side. The passive piece 41 projects from the opening 42 provided in the main body case 1 to the mounting portion 50 of the cap 7 in the switch-on state. By attaching the cap 7 to the attachment part 50, the previous passive piece 41 is pushed into the case, and the switch piece 23 and the operation knob 6 are forcibly turned off.
[0012]
A guide surface 44 for slidingly guiding the switch piece 23 and an inclined surface 45 for receiving the pressing portion 39 are provided on the inner surface of the case body 1. The fixed terminal 25 is provided on the slope 45. When the switch piece 23 is slid from the OFF state to the ON state, the inclined surface 45 is inclined with respect to the guide surface 44 so that the reaction force from the inclined surface 45 acting on the pressing portion 39 gradually increases.
[0013]
[Effects of the invention]
The switch piece 23 is provided with a pressing portion 39 that extends beyond the contact / separation piece 37 of the movable terminal 24 toward the fixed terminal 25, and the pressing portion 39 is a switch of the fixed terminal 25 when the operation knob 6 is turned on. Since the contact / separation piece 37 is brought into contact with the fixed terminal 25 in a state in which the portion 25a is pressed and held in an appropriate posture, even if the fixed terminal 25 is displaced with respect to the case body 1 for some reason, the posture is corrected. Thus, the contact / separation piece 37 can be reliably brought into contact with the switch portion 25a, and the contact / separation piece 37 of the movable terminal 24 can be prevented from being caught by the fixed terminal 25. Therefore, it is possible to obtain a highly reliable switch structure for an electrical device that can reliably perform an on / off operation even when it is subjected to a drop impact or rough handling.
[0014]
The switch part 25a of the fixed terminal 25 is arranged in a direction intersecting with the sliding direction of the movable terminal 24, and the left and right sides of the intersection of the sliding locus of the movable terminal 24 and the switch part 25a are fixed to the inner surface of the case body 1. According to the terminal fixing structure to be performed, it is possible to easily assemble the electrically conductive portion other than the switch portion 25a with respect to the case main body 1, so that it is possible to save assembling work. The important switch portion 25a is accurately positioned by, for example, welding or press-fit engagement, and is firmly fixed so as not to float from the inner surface of the case. Therefore, the reliability of the switch structure is further improved, and it is fatal in the switch structure. Can eliminate any bad contact.
[0015]
According to the switch structure in which the switch portion 25a of the fixed terminal 25 can be pressed and held by the pressing portion 39 of the switch piece 23 even when the switch is turned off, whether the switch is in use or not in use. Regardless of the reason, the pressing portion 39 can always prevent the fixed terminal 25 from being lifted away or displaced from the inner surface of the case, so that the contact failure of the switch or the contact state becomes unstable when the switch mechanism is turned on next time. Can be reliably prevented, and the reliability can be further improved accordingly.
[0016]
When the pressing part 39 of the switch piece 23 and the contacting / separating piece 37 of the movable terminal 24 are arranged adjacent to each other with a gap between them, the pressing part 39 and the contacting / separating piece 37 are arranged adjacent to each other in the thickness direction of the switch piece 23. Compared to the above, since it is not necessary to provide a space allowing the elastic deformation of the contact / separation piece 37 between the pressing portion 39 and the contact / separation piece 37, the entire thickness dimension of the switch structure is reduced accordingly, and the case body The space in 1 can be used effectively.
[0017]
According to the switch structure that holds and holds the inner surface of the pressing portion 39 of the switch piece 23 in the OFF state by the peripheral surface 4a of the motor 4, a part of the external force acting on the pressing portion 39 is received by the previous peripheral surface 4a, The elastic deformation of the pressing part 39 can be suppressed, and thereby the fixed terminal 25 can be prevented from being lifted or displaced more reliably.
[0018]
According to the switch structure in which the inner surface of the free end of the pressing portion 39 of the switch piece 23 is received and held by the inner receiving wall 48 provided in the case body 1 in the switch-off state, the pressing portion 39 can be turned on or off. The free end can be pushed and its lifting can be reliably controlled, and therefore the fixed terminal 25 can be further reliably prevented from being lifted off or displaced from the inner surface of the case. Further, since the switch piece 23 can be supported at both ends by the peripheral surface of the motor 4 and the inner receiving wall 48, the pressing reaction force that the pressing portion 39 receives from the fixed terminal 25 compared to the case where the pressing portion 39 is cantilevered. And the fixed terminal 25 can be pressed with a larger force.
[0019]
The passive piece 41 provided at the protruding end of the switch piece 23 on the pressing portion 39 side is protruded from the opening 42 provided in the main body case 1 to the attachment portion 50 of the cap 7 in the switch-on state, and the cap 7 is attached to the attachment portion 50. Thus, according to the switch mechanism for forcibly turning off the switch piece 23 and the operation knob 6 via the passive piece 41, the cap 7 is mounted on the case body 1 while the switch is turned on by mistake. In such a case, it is possible to prevent the battery 5 from being consumed wastefully by switching the switch to the OFF state. Furthermore, the operation button 6 can be well prevented from being switched to the on position while the cap 7 is attached.
[0020]
When the switch piece 23 is slid from the OFF state to the ON state, the inclined surface 45 is inclined with respect to the guide surface 44 for the switch piece 23 so that the reaction force from the inclined surface 45 acting on the pressing portion 39 gradually increases. According to the switch structure, the closer the movable terminal 24 is to the fixed terminal 25, the stronger the fixed terminal 25 is pressed by the pressing portion 39, and the posture of the fixed terminal 25 can be optimized. And the switch portion 25a can be contacted properly and reliably.

[0029]
The operation knob 6 is composed of an elliptical button that is long in the vertical direction, and an outer coupling body 38 projects from the inner surface thereof. By press-fitting and engaging the outer coupling body 38 with the inner coupling body 31 of the switch piece 23, both the parts 23 and 38 can be slid up and down along the guide groove 22, and the energized state of the motor 4 is turned on / off. it can. In order to reduce the space occupied by the switch structure inside the case main body 1 and to realize a thinner and more compact case main body 1, both the inner and outer coupling bodies 31 and 38 are connected to the operation knob 6. A connection is made between the outer surface and the inner surface of the switch piece 23. Specifically, as shown in FIG. 11, the engaging claw of the outer connecting body 38 is fitted and engaged with the engaging step on the inner surface of the inner connecting body 31, and the engaging claw protrudes from the lower surface of the inner connecting body 31. Is preventing.
[0030]
In the state where the operation knob 6 and the switch piece 23 are assembled to the main body case 1 as described above, the switch piece 23 is slidably guided and supported by the front case 8 a and the flat peripheral surface 4 a of the motor 4. Specifically, the inner surface and the outer surface of the base portion 31c of the inner coupling body 31 are slidably guided by the guide surface 44 formed in the front case 8a and the flat peripheral surface 4a of the motor 4, and the inner surface of the pressing portion 39 is guided by the motor 4. The flat peripheral surface 4a is received. On both upper half portions of the guide surface 44, there are provided a base portion 31c and guide ribs 46 for receiving both side surfaces of the frame portion 34 (see FIG. 10). In addition, a slope 45 that receives the previous pressing portion 39 is provided continuously from the upper end of the guide surface 44, and the fixed terminal 25 is disposed in the middle thereof. As shown in FIG. 1, when the slope 45 is inclined with respect to the guide surface 44 and the switch piece 23 is slid from the off state to the on state, the reaction force received by the pressing portion 39 from the slope 45 gradually increases. Provided. Actually, since the inner case 1A has an upwardly tapered shape, the inner surface of the front case 8a is used as it is as the inclined surface 45, and the guide surface 44 is recessed so as to be parallel to the flat peripheral surface 4a of the motor 4. Not.
[0031]
In the assembled state, the left and right side surfaces of the inner coupling body 31 of the switch piece 23 are regulated and guided so as not to expand by the inner side surface 22a of the guide groove 22 on the inner case 1A side. The expansion deformation is also restricted by the frame portion 34 fitted around the peripheral surface. Therefore, the engagement state of the inner and outer coupling bodies 31 and 37 is not released even when receiving a drop impact.
[0032]
A switch mechanism is provided between the switch piece 23 and the front case 8a (inner case 1A) in order to hold the switch piece 23 at each on / off position and to give a click feeling during switching. 7 and 10, the movement mechanism is constituted by the pair of movement parts 32 of the switch piece 23 described above and the movement protrusions 40 provided on the inner surface of the front case 8a. As shown in FIG. 7, the joint protrusion 40 is provided on the opening edge of the front case 8 a so as to be opposed to the left and right by using an opening formed in the peripheral wall. Although the peripheral wall of the inner case 8a is formed in a semicircular cross section, the left and right sides of the slide range of the switch piece 23 are slightly recessed from the inner peripheral surface of the inner case 8a to form the guide surface 44. Further, the previous joint protrusion 40 is slightly protruded from the inner peripheral surface of the inner case 8a. Therefore, the upper corner of the projecting piece 33 of the joint portion 32 and the lower corner of the joint projection 40 are overlapped in the sliding direction as shown in FIG. Therefore, when the operation knob 6 is slid up and down, the projecting piece 33 gets over the joint projection 40 while elastically deforming the joint portion 32 in the right and left direction.
[0033]
As shown in FIG. 14, when the operation knob 6 is slid to the ON side, the passive piece 41 provided at the upper end of the switch piece 23 is removed from the opening 42 provided in the step portion for the cap 7 of the front case 8a. The inner surface of the pressing portion 39 including the passive piece 41 rides on the outer surface of the outer wall 47 on the side of the paragraph portion facing the opening 42. In this state, since the pressing portion 39 is received by the outer receiving wall 47 against the pressing reaction force of the fixed terminal 25, the switch portion 25a can be pressed with a stronger force than in the switch-off state. Immediately after this, the contact / separation piece 37 rides on the switch portion 25a, so that the contact / separation piece 37 can be reliably prevented from being caught by the switch portion 25a.
[0034]
Further, when the operation knob 6 is switched to the on state, the passive piece 41 protrudes from the opening 42 to the mounting portion 50 of the cap 7, and the middle portion of the pressing portion 39 is received by the outer receiving wall 47. That is, the switch piece 23 is supported by the peripheral surface of the motor 4 and the outer wall 47 in a both-end supported state. Therefore, even when a drop impact acts on the case body 1 in the on state, the switch piece 23 can be reliably prevented from moving and the switch portion 25a can be prevented from being lifted or displaced. Incidentally, in this state, the switch portion 25 a is pressed and held by the pair of joint portions 32 that sandwich the elastic arm 36.
[0035]
When the cap 7 is mounted on the case main body 1 with the operation knob 6 kept on, the passive piece 41 protruding from the mounting portion 50 comes into contact with the opening edge of the cap 7 and is pushed back into the case. . As a result, each of the switch piece 23 and the operation knob 6 is forcibly slid by the cap 7 and switched to the off position. Therefore, it is possible to prevent the battery 5 from being wasted. Further, the operation button 6 can be well prevented from being switched to the on position while the cap 7 is attached.
[0036]
15 and 16 show another embodiment of the switch mechanism. In this case, an inner receiving wall 48 is projected downward continuously from the lower end of the outer receiving wall 47 facing the opening 42, and the inner surface of the free end of the pressing portion 39 of the switch piece 23 is received by the inner receiving wall 48 in the off state. I was able to. As described above, when the lifting of the pressing portion 39 in the off state is restricted by the inner receiving wall 48, the lifting of the pressing portion 39 from the inner surface of the case is surely restricted, and the fixed terminal 25 is further lifted and displaced more reliably. Can be prevented. Further, since the switch piece 23 can be supported at both ends by the peripheral surface of the motor 4 and the inner receiving wall 48, the fixed terminal 25 can be pressed with a greater force than when the pressing portion 39 is supported at the cantilever. . The timing at which the contact / separation piece 37 rides on the switch portion 25a immediately after the pressing portion 39 rides on the outer surface of the outer receiving wall 47 is the same as in the previous embodiment.
[0037]
In addition to the above-described embodiment, the fixed terminal 25 can be configured by only the switch portion 25a. In this case, the switch portion 25a and the presser spring 26 can be connected by a lead wire. The pressing portion 39 is preferably configured to always hold and hold the fixed terminal 25 even in the off state, but at least when the operation button 6 is turned on, the fixed terminal 25 precedes the contact / separation piece 37 of the movable terminal 24. Any structure that can hold the presser foot is acceptable. The base portion 31 c of the switch piece 23 can be slidably guided by the flat surface of the circuit board disposed adjacent to the flat peripheral surface 4 a of the motor 4 and the guide surface 44. The case body 1 does not need to be double inside and outside. The switch mechanism may be structured to be switched from the 3 position to the 4 position. A link mechanism or the like may be interposed between the operation knob and the switch piece 23. In addition, the function of the cap 7 changes according to the difference in an electric equipment, for example, in the case of an electric toothbrush, it will provide in order to maintain the sanitary state of a brush part.
