Description

Electronic component, switch, and electronic device

Technical Field

The present disclosure relates to an electronic component, a switch, and an electronic device.

Background

Electronic components are known in which various functions are added to a switch. For example, japanese patent application laid-open No. 2007-226995 (hereinafter referred to as patent document 1) describes an electronic component in which a conductive layer formed by printing a conductive resin on a waterproof sheet covering an upper surface is electrically connected to a pattern for grounding formed on a substrate. The electronic component described in patent document 1 can easily form an antistatic ground electrode on the upper portion of the waterproof sheet by making the conductive layer formed on the waterproof sheet conductive to the grounding pattern.

In addition, for electronic parts mounted in portable devices and having a switching function, it is desired to realize miniaturization while mounting various functions other than the switching function. For example, in the input device described in japanese patent application laid-open No. 2010-123367 (hereinafter referred to as patent document 2), a switch is connected to a detection circuit capable of detecting both a change in electrostatic capacitance corresponding to a contact of a finger and a pressing operation by the finger, whereby the contact of the finger with the switch can be detected in addition to the detection of the pressing operation. The input device described in patent document 2 uses a fixed contact and a movable contact of a switch as electrodes of a capacitance detection capacitor, and can thereby detect contact of a finger with the switch in addition to detection of a pressing operation without changing the size of the switch.

Disclosure of Invention

On the other hand, the industry is researching mobile terminals such as wearable devices that implement the following functions: biological information such as an Electrocardiogram (ECG) is acquired by acquiring a current from a human body through a switch. By mounting the electronic component described in patent document 1 on a mobile terminal, it is possible to obtain a current from a human body through the conductive layer formed on the waterproof sheet of the electronic component described in patent document 1.

However, in the electronic component described in patent document 1, since the conductive layer is formed on the waterproof sheet, the conductive layer may be peeled off from the waterproof sheet by repeated pressing operations over the years. When the conductive layer is detached from the waterproof sheet, a path through which current supplied from the human body flows is cut off, and the mobile terminal cannot acquire biological information any more. In addition, when a conductive resin is used for the conductive layer, the printed conductive resin has a higher resistance value than metal, and thus there is a concern that the accuracy of detecting biological information may be lowered.

Detailed Description

Next, the electronic component, the switch, and the electronic device of the present disclosure will be described with reference to the drawings. It should be noted that the technical scope of the present invention is not limited to the embodiments, but encompasses the invention described in the claims and their equivalents.

(constitution and function of electronic component of the embodiment)

Fig. 1 (a) is a front view of an electronic device according to an embodiment, and fig. 1 (b) is a rear view of the electronic device shown in fig. 1 (a).

The electronic device 100 is a smart watch including a case 101, an operation member 102, a touch panel 103, a back electrode 104, a control device 110, and an electronic component 1, and is worn on a wrist of an operator who operates the electronic device 100 via a wristband 120.

The case 101 is formed of a synthetic resin such as polycarbonate and a material having high hardness and low corrosiveness such as ceramics, and houses the operating member 102, the control device 110, and the components of the electronic device 100 such as the electronic component 1. The operation member 102 is made of a high-hardness steel material, and has one end protruding outside the case 101 and the other end disposed so as to contact the electronic component 1 and be contacted and pressed by an operator.

The touch panel 103 is disposed in a substantially rectangular opening formed in the surface of the casing 101. The touch panel 103 is protected by a watch glass formed of a high-hardness and transparent material such as sapphire glass or inorganic glass. The touch panel 103 outputs input information corresponding to an operation by an operator to the control device 110, and displays an image corresponding to the output information output from the control device 110.

The back electrode 104 is formed of a conductive member such as metal, and is disposed in a circular opening formed in the surface of the case 101. The back electrode 104 is electrically connected to the control device 110, forming a current path between the control device 110 and the wrist of the operator when the operator wears the electronic apparatus 100 on the wrist.

The control device 110 is, for example, a semiconductor circuit such as a central processing unit (Central Processing Unit, CPU), and is disposed inside the casing 101. The control device 110 performs arithmetic processing on input information input from the operation member 102 and the touch panel 103, generates output information corresponding to an image displayed on the touch panel 103, and outputs the generated output information to the touch panel 103. Input information input from the operation member 102 is input to the control device 110 via the electronic component 1.

The electronic component 1 is disposed inside the case 101, is electrically connected to the control device 110, and outputs a signal corresponding to an operation by an operator to the control device 110. When the operator touches the operation member 102 with his/her finger, the electronic component 1 forms a current path between the control device 110 and the operator's finger, receives a biological signal representing biological information such as ECG, and outputs the received biological signal to the control device 110. When the operator presses the operation member 102 with a finger, the electronic component 1 outputs a turn-on signal indicating that the operation member 102 has been pressed to the control device 110.

Fig. 2 (a) is an exploded perspective view of a portion shown by a one-dot chain line a in fig. 1 (a), and fig. 2 (b) is a perspective view of the operation member 102, the electronic component 1, and the substrate on which the electronic component 1 is mounted shown in fig. 1 (a).

The electronic device 100 further has a spring member 105, a receiving member 106, a washer 107, and a substrate 108. The spring member 105 and the receiving member 106 are disposed in the vicinity of the opening 109 so as to be movable together with the operating member 102. The operating member 102 has a crown 121 and a stem 122. The crown 121 has a substantially cylindrical shape, and is configured in such a manner that the upper surface protrudes outside the case 101 so as to be operable by an operator. The stem 122 has a substantially circular shape having a diameter shorter than that of the crown 121 and a height longer than that of the crown 121, and extends downward from the lower surface of the crown 121.

The spring member 105 is an elastic member, also called a coil spring or a coil spring, and is housed in the housing member 106 such that one end contacts the lower surface of the crown 121 and the other end contacts the housing member 106. Further, the spring member 105 is penetrated by the stem 122. As the upper surface of crown 121 is pressed by the operator, spring member 105 is compressed, and when the operator finishes pressing the upper surface of crown 121, spring member 105 is restored.

The housing member 106 is formed of synthetic resin such as epoxy resin, and houses the operation member 102 and the spring member 105. The receiving member 106 has a through hole through which the stem 122 passes, and has a bottom surface for holding the crown 121 and a bottom surface for holding the spring member 105, which is disposed between the bottom surface for holding the crown 121 and the through hole.

The washer 107 is a spring washer, and is disposed between the housing member 106 and the electronic component 1, and the stem 122 penetrates. As the upper surface of the crown 121 is pressed by the operator, the washer 107 deforms, and when the operator ends the pressing of the upper surface of the crown 121, the washer 107 recovers.

The substrate 108 is a flexible printed circuit board (Flexible printed circuits, FPC) and has a 1 st substrate electrode 181, a 2 nd substrate electrode 182, a 3 rd substrate electrode 183, and a 4 th substrate electrode 184, and electrically connects the electronic component 1 and the control device 110. The 1 st substrate electrode 181, the 2 nd substrate electrode 182, the 3 rd substrate electrode 183, and the 4 th substrate electrode 184 are connected to connection electrodes formed on the outer edge of the electronic component 1 by soldering.

The 1 st contact 21 is formed of a metal foil such as copper, and is a conductor having a substantially circular planar shape and disposed in a central portion of the surface of the base material 20. The 2 nd contact 22 is formed of a metal foil such as copper, and is a conductor having a frame-like planar shape disposed on the surface of the substrate 20 so as to surround the 1 st contact 21. The 2 nd contact 22 is arranged to contact the outer edge of the movable contact 13, and the 1 st contact 21 contacts the top of the movable contact 13 when the movable contact 13 performs the tilting operation.

The 3 rd contacts 23a and 23b are formed of a metal foil such as copper, and are a pair of rectangular conductors extending in the short side direction of the substrate 20, which are disposed near the ends in the long side direction of the surface of the substrate 20. The 3 rd contacts 23a and 23b are arranged to contact the lower end of the elastic member 16.

The 1 st back electrode 24 is electrically connected to the 1 st contact 21 via a conductor filled in the via hole 28 a. The 1 st back electrode 24 is formed on the inner wall of the recess 27a and electrically connected to a connection electrode soldered when the electronic component 1 is mounted on the substrate 108.

The 2 nd back electrode 25 is electrically connected to the 2 nd contact 22 via a conductor filled in the via hole 28 b. The 2 nd back electrode 25 is formed on the inner wall of the recess 27b and electrically connected to a connection electrode soldered when the electronic component 1 is mounted on the substrate 108.

The 3 rd back electrode 26 is electrically connected to the 3 rd contacts 23a and 23b via conductors filled in the through holes 28c and 28 d. The 3 rd back electrode 26 is formed on the inner wall of the concave portions 27c and 27d, and is electrically connected to a connection electrode soldered when the electronic component 1 is mounted on the substrate 108.

The frame material 12 is made of a resin material such as polyimide, and has the same outer shape as the outer shape of the switch board 11. The frame 12 has a 1 st through hole 12a, a 2 nd through hole 12b and a 12c. The 1 st through hole 12a is formed in the central region of the frame 12, and forms a housing portion in which the 1 st contact 21, the 2 nd contact 22, the movable contact 13, and the pressing member 14 are disposed together with the surface 20a of the switch substrate 11. The 2 nd through hole 12b is formed near one end of the frame 12 in the longitudinal direction, and is disposed so as to surround the 3 rd contact 23 a. The 2 nd through hole 12c is formed near the other end of the frame 12 in the longitudinal direction and is disposed so as to surround the 3 rd contact 23 b.

The movable contact 13 has a 1 st movable contact 13a, a 2 nd movable contact 13b, and a 3 rd movable contact 13c. The 1 st movable contact 13a, the 2 nd movable contact 13b, and the 3 rd movable contact 13c are each formed of an elastic conductive member such as stainless steel or copper, which is thin and formed into a dome shape, and are arranged to overlap with each other so as to be insulated from the 1 st contact 21 and to be electrically connected to the 2 nd contact 22. The 1 st movable contact 13a, the 2 nd movable contact 13b, and the 3 rd movable contact 13c are formed by cutting a convex dome-shaped plate spring member so as to have a grass bag shape with opposing sides.

The pushing member 14 is made of a resin material such as polyimide having a cylindrical shape, and is a pressing member disposed above the center portion of the 3 rd movable contact 13c. By disposing the pushing member 14, the operability of the pressing operation of the switch 10 is improved.

The sealing sheet 15 is a sheet made of a flexible synthetic resin such as polyimide, and protects the 1 st contact 21, the 2 nd contact 22, the movable contact 13, and the pushing member 14 which are housed in a housing portion formed by the surface 20a of the switch substrate 11 and the 1 st through hole 12 a. The sealing sheet 15 is fixed to the frame 12 by being adhered to the surface of the frame 12 so as to cover the storage portion formed by the switch board 11 and the frame 12.

The sealing sheet 15 has an inclined portion 15a and a pressing portion 15b, and forms a 1 st opening portion 15c and a 2 nd opening portion 15d. The inclined portion 15a is inclined so as to cover the outer edges of the 1 st movable contact 13a, the 2 nd movable contact 13b, and the 3 rd movable contact 13c protruding from the 1 st through hole 12a, and the pressing portion 15b is formed in a flat surface so as to cover the pressing piece 14. The 1 st opening 15c is formed near one end of the frame 12 in the longitudinal direction and is disposed so as to surround the 3 rd contact 23 a. The 2 nd opening 15d is formed near the other end of the frame 12 in the longitudinal direction and is disposed so as to surround the 3 rd contact 23b. The sealing sheet 15 seals the 1 st through hole 12a, and does not seal the 2 nd through holes 12b and 12c.

Fig. 7 is a circuit diagram of the switch 10.

The switch 10 has a 1 st input terminal IN1, a 2 nd input terminal IN2, a 1 st output terminal OUT1, a 2 nd output terminal OUT2, a 3 rd output terminal OUT3, and a 4 th output terminal OUT4. The 1 st input terminal IN1 and the 2 nd input terminal IN2 correspond to the 3 rd contacts 23a and 23b. The 1 st output terminal OUT1 and the 2 nd output terminal OUT2 correspond to the connection electrodes arranged in the concave portions 27a and 27b, and the 3 rd output terminal OUT3 and the 4 th output terminal OUT4 correspond to the connection electrodes arranged in the concave portions 27c and 27 d.

When the pressing portion 15b is pressed, the movable contact 13 contacts the 1 st contact 21, and the switch 10 is turned on, so that the 1 st output terminal OUT1 and the 2 nd output terminal OUT2 are turned on. The 1 st input terminal IN1 and the 2 nd input terminal IN2 are arranged so that the lower ends of the elastic members 16 are brought into contact, whereby a current circuit is formed between the finger of the operator who touches the operation member 102 and the control device 110 via the pressing member 17.

Fig. 8 is a perspective view of the elastic member 16 and the pressing member 17, and fig. 9 is an exploded perspective view of the elastic member 16 and the pressing member 17. The elastic member 16 is disposed between the switch 10 and the pressing member 17 so that the lower end thereof contacts the 3 rd contacts 23a and 23b, and functions as an elastic portion that movably supports the pressing surface 41. The pressing member 17 has a pressing surface 41 and is disposed above the switch 10. The elastic member 16 and the pressing member 17 are the following conductive pressing members: the switch 10 has a conductive pressing surface 41 arranged above the switch 10, and the lower end contacts the 3 rd contact of the switch 10 and supports the pressing surface.

The elastic member 16 is formed by plating a plating layer of gold, silver, palladium, or the like having high electrical conductivity on a material having high spring properties such as phosphor bronze, and has a pair of leg portions 31a and 31b, a pair of contact portions 32a and 32b, a top portion 33, a pair of connection portions 34a and 34b, a pair of support portions 35a and 35b, and fitting portions 36a, 36b, 36c, and 36d. As the pressing face of the pressing member 17 is pressed, the elastic member 16 moves the pressing member 17 toward the upper surface of the switch 10.

The leg portion 31a extends from the top portion 33 to the contact portion 32a while being bent upward. The leg portion 31b extends from the top portion 33 to the contact portion 32b while being bent upward in a direction opposite to the extending direction of the leg portion 31 a. The leg portions 31a and 31b form elastic portions having a convex shape toward the pressing member 17 about the top portion 33, are disposed between the pair of support portions 35a and 35b, and are connected to both of the pair of support portions 35a and 35 b. The pair of contact portions 32a and 32b have rectangular planar shapes, and are disposed at the lower end of the elastic member 16 along the inner side walls of the 2 nd through holes 12b and 12c of the frame 12. Since the inner walls of the 2 nd through holes 12b and 12c of the frame 12 are provided, the pair of contact portions 32a and 32b are easily inserted. The pair of contact portions 32a and 32b are fixedly connected to the 3 rd contacts 23a and 23b by soldering, bonding with a conductive resin, or the like so that the contact portions 32a and 32b do not slide. The pair of contact portions 32a and 32b are thinner than the frame 12, and are protected from external force. Further, even if solder or an adhesive adheres to the upper surfaces of the pair of contact portions 32a and 32b, other members or the like are not contacted, and thus an electrical short circuit does not occur.

The top 33 has a rectangular planar shape and is disposed between the pair of legs 31a and 31 b. The pair of connecting portions 34a and 34b are connected to a pair of opposite sides of the top portion 33 to which the pair of legs 31a and 31b are not connected. The pair of support portions 35a and 35b are flat plate-like members extending in parallel with the pair of leg portions 31a and 31b interposed therebetween, and support the pressing member 17 along the opposite long sides of the pressing member 17.

The fitting portions 36a and 36b are disposed at both ends of the support portion 35a, and clamp the pressing member 17 by being bent in a U shape. The fitting portions 36c and 36d are disposed at both ends of the support portion 35b, and clamp the pressing member 17 by being bent in a U shape. The fitting portions 36a, 36b, 36c, and 36d are sometimes collectively referred to as a fitting portion 36. The fitting portion 36 may be fixed by welding or the like.

The pressing member 17 has a pressing surface 41, and is a conductor such as a metal plated with a high-conductivity plating layer on a material having a high strength such as copper containing titanium or quenched steel, which has a substantially rectangular planar shape with notches 42a, 42b, 42c, and 42d formed in 4 corners. The notches 42a, 42b, 42c, and 42d are fitted into the fitting portions 36a, 36b, 36c, and 36d of the elastic member 16, whereby the pressing member 17 is fixed to the elastic member 16. Further, the notches 42a, 42b, 42c, and 42d are sometimes collectively referred to as notches 42.

The elastic member 16 supports the pressing member 17 along the opposite long sides of the pressing member 17, and thereby, regardless of which part of the pressing surface 41 is pressed, the pressing member 17 descends toward the switch 10 while maintaining the extending direction of the pressing surface 41 in the direction orthogonal to the pressing direction. The pressing member 17 is thicker than the elastic member 16, so that even if the operator presses the operation member 102 with a finger, it is not easily deformed. The elastic member 16 is thinner than the pressing member 17, so that the switching performance can be easily adjusted, and particularly, the click feeling can be enhanced.

The electronic component 1 is fixed to the 3 rd contacts 23a and 23b of the switch 10 by soldering by fitting the fitting portion 36 into the notch 42 of the pressing member 17 and the contact portions 32a and 32b of the elastic member 16 integrated with the pressing member 17.

Fig. 10 is a diagram showing the electronic device 100 worn on the left wrist of the operator.

The electronic device 100 is worn on the left wrist 200a of the operator by means of the wristband 120. When the index finger 200b of the right hand of the operator contacts the operation member 102, the operation member 102 contacts the electronic component 1, and a current circuit through which a current flowing through the human body of the operator flows is formed.

Fig. 11 is a diagram showing a circuit diagram of a current circuit formed by the contact of the index finger 200b of the right hand of the operator with the operation member 102 of the electronic apparatus 100 worn on the left wrist 200a of the operator.

The electronic device 100 further has a pull-up resistor 111, a buffer 112, and an AD conversion circuit 113. In the pull-up resistor 111, one end is supplied with the power supply voltage Vdd, and the other end is connected between the back electrode 104 and the buffer 112. The pull-up resistor 111 converts a current flowing through the formed current circuit into a voltage indicating the potential of the operator 200. The buffer 112 amplifies the voltage indicating the potential of the operator 200 and outputs the amplified voltage to the AD conversion circuit 113. The AD conversion circuit 113 converts the voltage input from the buffer 112 into a digital signal and outputs the digital signal to the control device 110.

By wearing the electronic device 100 on the left wrist 200a of the operator 200, the left wrist 200a of the operator 200 is brought into contact with the back electrode 104, and the left wrist 200a of the operator 200 is electrically connected to the pull-up resistor 111 and the buffer 112. Further, by the contact of the index finger 200b of the operator's right hand, the index finger 200b of the operator's right hand is electrically connected to the crown 121 of the operation member 102. Further, by the contact of the index finger 200b of the right hand of the operator, the stem 122 of the operation member 102 is electrically connected to the pressing member 17 of the electronic component 1.

The 3 rd contacts 23a and 23b, the elastic member 16, and the pressing member 17 form a circuit through the operator 200 by the operation member 102, which is a conductive pressing member, disposed above the pressing surface 41 being pressed by the operator 200, which is a human body, to contact the pressing surface 41. Further, when the operator 200 presses the operation member 102 further, the pressing surface 41 presses the movable contact 13 disposed on the upper surface of the substrate 11 of the switch 10, and the movable contact 13 performs the tilting operation, so that the 1 st contact 21 and the 2 nd contact 22 are turned on.

(effects of the electronic component according to embodiment 1)

The electronic component 1 forms a current path by a conductive pressing member 17 disposed above the switch 10 and a conductive elastic member 16 disposed between the switch 10 and the pressing member 17 and having a lower end in contact with the 3 rd contacts 23a and 23 b. Since the current circuit is formed via the conductive elastic member 16 and the pressing member 17 disposed above the switch 10, the electronic component 1 can form a current path which is less likely to deteriorate over time regardless of the pressing operation for the switch.

In addition, for example, when a current path between the operation member 102 and the switch 10 is formed by 1 leaf spring, the thickness of the leaf spring disposed in the current path becomes thicker in order to prevent deformation when in contact with the pusher 14. If the thickness of the plate spring disposed in the current path is increased, the click feeling when the operator presses down the electronic component is reduced, which is undesirable.

The increase in the size of 1 leaf spring forming the current path can prevent the click feeling from being reduced when the operator presses down, but the increase in the size of the leaf spring is undesirable because it increases the size of the electronic component. In the electronic component 1, by forming the current path between the operation member 102 and the switch 10 by 2 members, that is, the elastic member 16 and the pressing member 17, a good click feeling can be achieved without increasing the size. Further, only one pair of the contact portions 32a and 32b may be fixedly connected to at least one of the 3 rd contacts 23a and 23 b. Since the stress of the unfixed leg portions 31a and 31b can be relaxed, the operation load of the elastic member 16 is reduced, and the click feeling is improved. The unfixed contact portions 32a and 32b are surrounded by the 2 nd through holes 12b and 12c even if sliding occurs, and thus, the insulation is ensured, and therefore, they do not come into contact with other members and do not short-circuit.

In the electronic component 1, since the pressing member 17 is supported by the pair of support portions 35a and 35b arranged to sandwich the leg portions 31a and 31b and extend in the extending direction of the pressing member 17, the pressing surface 41 is not inclined when the pressing surface 41 is pressed. Since the pressing member 17 is pressed without tilting the pressing surface 41, the electronic component 1 can increase the area of the contact surface of the stem 122 pressed by the pressing surface 41 with the pressing surface 41. Since the area of the contact surface of the stem 122 with the push down surface 41 can be increased, the electronic component 1 can reduce the occurrence of noise caused by a fluctuation in the resistance value of the current path between the stem 122 and the push down surface 41 or the like.

In the electronic component 1, since the pair of support portions 35a and 35b extend parallel to the longitudinal direction of the pressing member 17, the pressing member 17 is supported more stably, and an increase in the area of the contact surface of the stem 122 with the pressing surface 41 can be maintained.

In the electronic component 1, the leg portions 31a and 31b are connected to the pair of support portions 35a and 35b at the top portion 33, so that the movement distance increases, and the movement distance can be adjusted so as to achieve a desired click feeling.

In the electronic component 1, the elastic member 16 is fitted in the notches 42a, 42b, 42c, and 42d of the pressing member 17 to fix the pressing member, so that the possibility of the pressing member 17 being displaced in the horizontal direction can be reduced. The pressing member 17 is fixed in the longitudinal direction by the fitting portions 36a, 36b, 36c, 36d and the pressing surface 41, and in the lateral direction by the notches 42a, 42b, 42c, 42d, whereby the possibility of misalignment during assembly and operation is reduced.

(constitution and function of electronic component of embodiment 2)

Fig. 12 (a) is a perspective view of the electronic component according to embodiment 2, fig. 12 (B) is a cross-sectional view taken along line B-B of fig. 12 (a), and fig. 13 is an exploded perspective view of the electronic component shown in fig. 12 (a).

The electronic component 2 has a switch 210, an integrally formed pressing member 216, and a pair of leg members 217a and 217b, and can be mounted on the electronic device 100, as in the electronic component 1. The electronic component 2 is turned on by the pressing of the operation member 102 by the operator, and acquires the living body information such as ECG by acquiring the current from the operator by the operator touching the operation member 102.

The switch 210 includes a switch substrate 211, a frame 212, a movable contact 213, a pushing member 214, and a sealing sheet 215, and is turned on when the upper surface is pushed down, and is turned off when the upper surface is no longer pushed down.

Fig. 14 (a) is a top view of the switch substrate 211, and fig. 14 (b) is a bottom view of the switch substrate 211.

The switch substrate 211 has a base 220, a 1 st contact 221, a 2 nd contact 222, 3 rd contacts 223a and 223b, a 1 st back electrode 224, a 2 nd back electrode 225, and 3 rd back electrodes 226a and 226b. The base 220 is formed of a synthetic resin such as an epoxy resin, has a substantially rectangular planar shape, and has semicircular planar recesses 227a, 227b, 227c, and 227d formed near the ends of a pair of short sides.

The 2 nd contact 222 is formed of a metal foil such as copper, and is a conductor having a substantially U-shaped planar shape on the surface of the substrate 220 so as to surround the 1 st contact 221. The 2 nd contact 222 is arranged to contact the outer edge of the movable contact 213, and the 1 st contact 221 contacts the top of the movable contact 213 when the movable contact 213 performs a tilting operation.

The 3 rd contacts 223a and 223b are formed of a metal foil such as copper, and are a pair of rectangular conductors extending in the short side direction of the substrate 220, which are disposed near the ends in the long side direction of the surface of the substrate 220. The 3 rd contacts 223a and 223b are arranged to be connected to the lower ends of the pair of leg members 217a and 217b by soldering, welding, thermocompression bonding, or the like.

The 1 st back electrode 224 is electrically connected to the 1 st contact 221 via a conductor filled in the via hole 228 a. The 1 st back electrode 224 is formed on the inner wall of the recess 227a and electrically connected to a connection electrode soldered when the electronic component 2 is mounted on the substrate 108.

The 2 nd back electrode 225 is electrically connected to the 2 nd contact 222 via a conductor filled in the via hole 228 b. The 2 nd back electrode 225 is formed on the inner wall of the recess 227b and electrically connected to a connection electrode soldered when the electronic component 2 is mounted on the substrate 108.

The 3 rd back electrodes 226a and 226b are electrically connected to the 3 rd contacts 223a and 223b via conductors filled in the through holes 228c and 228 d. The 3 rd back electrodes 226a and 226b are formed on the inner walls of the recesses 227c and 227d, and are electrically connected to connection electrodes soldered when the electronic component 2 is mounted on the substrate 108.

The frame 212 is made of a resin material such as polyimide, and has the same outer shape as the outer shape of the switch substrate 211. The frame 212 has a through hole 212a, a 1 st notch 212b, and a 2 nd notch 212c. The through hole 212a is formed in the central region of the frame 212, and forms a housing portion in which the 1 st contact 221, the 2 nd contact 222, the movable contact 213, and the pressing member 214 are disposed together with the surface 220a of the switch substrate 211. The 1 st notch 212b has a substantially U-shaped planar shape, is formed near one end of the frame 212 in the longitudinal direction, and is disposed so as to surround the 3 rd contact 223 a. The 2 nd notch 212c has a substantially U-shaped planar shape opening in the opposite direction to the 1 st notch 212b, and is formed near the other end of the frame 212 in the longitudinal direction and is disposed so as to surround the 3 rd contact 223 b.

The movable contact 213 has a 1 st movable contact 213a, a 2 nd movable contact 213b, a 3 rd movable contact 213c, and a 4 th movable contact 213d. The 1 st movable contact 213a, the 2 nd movable contact 213b, the 3 rd movable contact 213c, and the 4 th movable contact 213d are each formed of an elastic conductive member such as stainless steel or copper, which is thin and formed into a dome shape. The 1 st movable contact 213a, the 2 nd movable contact 213b, the 3 rd movable contact 213c, and the 4 th movable contact 213d are arranged to overlap each other so as to be insulated from the 1 st contact 221 and to be electrically connected to the 2 nd contact 222. The 1 st movable contact 213a, the 2 nd movable contact 213b, the 3 rd movable contact 213c, and the 4 th movable contact 213d are formed by cutting a convex dome-shaped plate spring member so as to have a grass bag shape with opposing sides.

The pusher 214 is formed of a resin material such as polyimide having a cylindrical shape, and is disposed above the center portion of the 4 th movable contact 213d, as in the pusher 14. By disposing the pushing member 214, operability of the pressing operation of the switch 210 is improved.

The sealing sheet 215 is a sheet made of a flexible synthetic resin such as polyimide, and protects the 1 st contact 221, the 2 nd contact 222, the movable contact 213, and the pressing member 214 stored in the storage portion formed by the surface 220a of the switch substrate 211 and the through hole 212 a. The sealing sheet 215 is fixed to the frame 212 by being adhered to the surface of the frame 212 so as to cover the storage portion formed by the switch substrate 211 and the frame 212.

The seal piece 215 has an inclined portion 215a, a pressing portion 215b, a 1 st long side portion 215c, and a 2 nd long side portion 215d. The inclined portion 215a is inclined so as to cover the outer edges of the 1 st movable contact 213a, the 2 nd movable contact 213b, the 3 rd movable contact 213c, and the 4 th movable contact 213d protruding from the through hole 212 a. The pressing portion 215b is a top portion surrounded by the inclined portion 215a, and forms a plane so as to cover the pressing member 214. The 1 st long side 215c extends in the long side direction of the frame 212. The 2 nd long side 215d extends in the long side direction of the frame 212. The sealing piece 215 seals the through hole 212a, and does not seal the 1 st notch 212b and the 2 nd notch 212c.

The circuit configuration of the switch 210 is the same as that of the switch 10, and therefore a detailed description thereof is omitted here.

Fig. 15 (a) is a plan view of the pressing member 216 and the pair of leg members 217a and 217b, fig. 15 (b) is a side view of the pressing member 216 and the pair of leg members 217a and 217b, and fig. 15 (c) is a front view of the pressing member 216 and the pair of leg members 217a and 217b. The pressing member 216 and the pair of leg members 217a and 217b are the following conductive pressing members: the lower end of the pressing portion contacts the 3 rd contact of the switch 210 and supports the pressing surface, and the pressing portion 215b of the switch 210 is pressed by the pressing surface as the pressing surface is pressed.

The pressing member 216 and the pair of leg members 217a and 217b are integrally formed of a material having high spring properties such as phosphor bronze, and a plating layer such as gold, silver, palladium, or the like having high electrical conductivity. The pressing member 216 has a pressing surface 216a disposed above the pressing portion 215b of the switch 210. The pressing member 216 has a rectangular planar shape, and a pair of leg members 217a and 217b are connected to a pair of diagonal portions via a pair of concave portions 216b and 216c extending in the longitudinal direction. By forming the pair of concave portions 216b and 216c between the pressing member 216 and the pair of leg members 217a and 217b, the rigidity of the pressing member 216 and the pair of leg members 217a and 217b is improved, and the possibility that the pressing force applied to the switch 10 is reduced due to bending of the pressing member 216 and the leg members 217a and 217b when the pressing surface 216a is pressed can be reduced.

The foot member 217a has a 1 st extension 231, a 2 nd extension 232, and a 3 rd extension 233, and is supported in such a manner that the pressing member 216 can be moved toward the pressing portion 215b together with the foot member 217b as the pressing surface 216a is pressed. The 1 st extension 231 has one end connected to the pressing member 216, and extends from the pressing portion 215b side toward the end side in the longitudinal direction of the switch substrate 211 in parallel with the extending direction of the surface of the switch substrate 211. The end portion in the longitudinal direction, to which the 1 st extension 231 extends, is arranged to overlap with the end portion of the switch substrate 211. The surface inside the 1 st extension 231 extends parallel to the extending direction of the surface of the switch substrate 211. On the other hand, the surface outside the 1 st extension 231 extends obliquely from the extending direction of the surface of the switch substrate 211 so that the end portion approaches the surface of the switch substrate 211.

The 2 nd extension 232 extends from the end portion side of the switch substrate 211 toward the pressing portion 215b side while being bent. One end of the 2 nd extension 232 is connected to the other end of the 3 rd extension 233, and the other end of the 2 nd extension 232 is configured to contact the 3 rd contact 223a. The bottom surface of the tip of the 2 nd extension 232 is a rectangular flat surface, and is fixed to the 3 rd contact 223a by soldering. The bottom surface of the tip of the 2 nd extension 232 is surrounded by the 1 st notch 212b, thereby restricting movement.

The 3 rd extension 233 extends along one short side of the switch substrate 211 in the extending direction of the surface of the switch substrate 211. The 3 rd extension 233 has one end connected to the 1 st extension 231 and the other end connected to the 2 nd extension 232, and thus connects the 1 st extension 231 and the 2 nd extension 232 when the end is curved in an arc shape. The 3 rd extension 233 forms an inverted S-shaped planar shape together with the 2 nd extension 232.

Foot member 217b has a 1 st extension 236, a 2 nd extension 237, and a 3 rd extension 238, and as pressing surface 216a is pressed, pressing member 216 is moved toward pressing portion 215b together with foot member 217 a. The 1 st extending portion 236 has one end connected to the pressing member 216, and extends from the pressing portion 215b side toward the end portion side of the switch substrate 211 in parallel with the extending direction of the surface of the switch substrate 211. The end portion in the longitudinal direction, to which the 1 st extension portion 236 extends, is arranged to overlap with the end portion of the switch substrate 211. The surface inside the 1 st extension 236 extends parallel to the extending direction of the surface of the switch substrate 211. On the other hand, the surface outside the 1 st extension 236 extends obliquely from the extending direction of the surface of the switch substrate 211 so that the end portion approaches the surface of the switch substrate 211.

The 2 nd extension 237 extends from the end of the switch substrate 211 toward the pressing portion 215b while being bent. One end of the 2 nd extension 237 is connected to the other end of the 3 rd extension 238, and the other end of the 2 nd extension 237 is configured to contact the 3 rd contact 223b. The bottom surface of the tip of the 2 nd extension 232 is a rectangular flat surface, and is fixed to the 3 rd contact 223a by soldering. The bottom surface of the tip of the 2 nd extension 237 is surrounded by the 1 st notch 212b, thereby restricting movement.

The 3 rd extension 238 extends along one short side of the switch substrate 211 in the extending direction of the surface of the switch substrate 211. The 3 rd extending portion 238 has one end connected to the 1 st extending portion 236 and the other end connected to the 2 nd extending portion 237, whereby the 1 st extending portion 236 and the 2 nd extending portion 237 are connected when the end portions are curved in an arc shape. The 3 rd extension 238 forms an inverted S-shaped planar shape together with the 2 nd extension 237.

Each of the pair of leg members 217a and 217b has a point-symmetrical shape with respect to the center point of the lower surface 216 a.

The pair of leg members 217a and 217b as elastic members support the pressing member 216 diagonally, whereby the pressing member 216 descends toward the switch 210 as the pressing surface 216a is pressed.

The electronic component 2 is fixed by soldering the tips of the 2 nd extensions 232 and 237 of the pair of leg members 217a and 217b to the 3 rd contacts 223a and 223b of the switch 210.

(effects of the electronic component according to embodiment 2)

The electronic component 2 is formed with a conductive pressing member 216 and a pair of leg members 217a and 217b disposed above the switch 210 to form a current path. Since the current circuit is formed via the conductive pressing member 216 and the pair of leg members 217a and 217b disposed above the switch 210, the electronic component 2 can form a current path that is less likely to deteriorate over time regardless of the pressing operation for the switch.

In the electronic component 2, the pair of leg members 217a and 217b each have 1 st extending portions 231 and 236 extending from the pressing portion 215b side toward the end portion side of the switch substrate 211 and 2 nd extending portions 232 and 237 extending from the end portion side of the switch substrate 211 toward the pressing portion 215b side. By providing the pair of leg members 217a and 217b each with an extension portion that reciprocates from the center toward the end of the substrate, the electronic component 2 can lengthen the pressing distance of the pressing surface 216a without increasing the substrate area.

In the electronic component 2, since the extending portions of the pair of leg members 217a and 217b extend to positions overlapping the end portions of the switch board 211, the pressing distance of the pressing surface 216a can be further increased.

In the electronic component 2, since the pair of leg members 217a and 217b further has the 3 rd extending portion extending along the short side of the switch board 211, the pressing distance of the pressing surface 216a can be further increased.

In the electronic component 2, the pair of leg members 217a and 217b are disposed in the 1 st notch 212b and the 2 nd notch 212c which are formed by opening along the long side of the switch board 211, so that soldering operation with the 3 rd contacts 223a and 223b is easier.

The electronic component 3 is turned on by the pressing of the operation member 102 by the operator of the electronic apparatus 100, and acquires the living body information such as ECG by acquiring the current from the operator by the operator touching the operation member 102.

The switch 310 includes a switch substrate 311, a frame 312, a movable contact 313, a pushing member 314, and a sealing plate 315, and is turned on when the upper surface is pressed, and is turned off when the upper surface is no longer pressed.

The 2 nd contact 322 is formed of a metal foil such as copper, and is a conductor having a substantially frame-like planar shape disposed on the surface of the substrate 320 so as to surround the 1 st contact 321. The 2 nd contact 322 is arranged so that the outer edge of the movable contact 313 contacts, and the 1 st contact 321 contacts the top of the movable contact 313 when the movable contact 313 performs a tilting operation.

The 3 rd contacts 323a and 323b are disposed near the ends of the surface of the base 320 in the longitudinal direction, have a rectangular planar shape extending in the short side direction of the base 320, and are disposed so as to be connectable to each of the pair of leg members 317a and 317b by soldering, welding, thermocompression bonding, or the like. The 3 rd contacts 323a and 323b are bonding portions that are not electrically connected to the pair of leg members 317a and 317b and bond the pair of leg members 317a and 317b to the switch 311.

The 1 st back electrode 324 is electrically connected to the 1 st contact 321 via a conductor filled in a through hole penetrating from the front surface to the back surface of the substrate 320. The 1 st back electrode 324 is formed on the inner wall of the concave portions 327a and 327b, and is electrically connected to a connection electrode soldered when the electronic component 3 is mounted on the substrate 108.

The 2 nd back electrode 325 is electrically connected to the 2 nd contact 322 via a conductor filled in a via hole penetrating from the front surface to the back surface of the substrate 320. The 2 nd back electrode 325 is formed on the inner wall of the concave portions 327c and 327d, and is electrically connected to a connection electrode soldered when the electronic component 3 is mounted on the substrate 108.

The frame 312 is made of a resin material such as polyimide, and has the same outer shape as the outer shape of the switch board 311. The frame 312 has a 1 st through hole 312a, a 2 nd through hole 312b, and a 3 rd through hole 312c. The 1 st through hole 312a is formed in the central region of the frame 312, and forms a housing portion in which the 1 st contact 321, the 2 nd contact 322, the movable contact 313, and the pressing tool 314 are disposed together with the surface 320a of the switch substrate 311. The 2 nd through hole 312b has a substantially rectangular planar shape, is formed near one end of the frame 312 in the longitudinal direction, and is disposed so as to surround the 3 rd contact 323 a. The 3 rd through hole 312c has a substantially rectangular planar shape, like the 2 nd through hole 312b, and is formed near the other end of the frame 312 in the longitudinal direction and is disposed so as to surround the 3 rd contact 323 b.

The movable contact 313 has a 1 st movable contact 313a, a 2 nd movable contact 313b, and a 3 rd movable contact 313c. The 1 st movable contact 313a, the 2 nd movable contact 313b, and the 3 rd movable contact 313c are each formed of an elastic conductive member such as stainless steel or copper, which is thin and formed into a dome shape, and are arranged to overlap so as to be insulated from the 1 st contact 321 and to be electrically connected to the 2 nd contact 322. The 1 st movable contact 313a, the 2 nd movable contact 313b, and the 3 rd movable contact 313c are formed by cutting a convex dome-shaped plate spring member so as to have a grass bag shape with opposing sides.

The pushing member 314 is made of a resin material such as polyimide having a cylindrical shape, and is a pressing member disposed above the center portion of the 3 rd movable contact 313c, as in the pushing member 14. By disposing the pushing member 314, operability of the pressing operation of the switch 310 is improved.

The sealing sheet 315 is a sheet made of a flexible synthetic resin such as polyimide, and protects the 1 st contact 321, the 2 nd contact 322, the movable contact 313, and the pressing tool 314 stored in the storage portion formed by the surface 320a of the switch substrate 311 and the 1 st through hole 312a of the frame 312. The sealing sheet 315 is fixed to the frame 312 by being adhered to the surface of the frame 312 so as to cover the storage portion formed by the switch substrate 311 and the frame 312.

The sealing sheet 315 has an inclined portion 315a, a pressing portion 315b, a 1 st opening 315c, and a 2 nd opening 315d. The inclined portion 315a is inclined so as to cover the outer edges of the 1 st movable contact 313a, the 2 nd movable contact 313b, and the 3 rd movable contact 313c protruding from the 1 st through hole 312 a. The pressing portion 315b is a top portion surrounded by the inclined portion 315a, and forms a plane so as to cover the pressing member 314. The 1 st opening 315c has a shape corresponding to the 2 nd through hole 312b, and the 2 nd opening 315d has a shape corresponding to the 3 rd through hole 312c. The sealing sheet 315 seals the 1 st through hole 312a, and does not seal the 2 nd through hole 312b and the 3 rd through hole 312c.

Fig. 19 (a) is a plan view of the pressing member 316 and the pair of leg members 317a and 317b, fig. 19 (b) is a side view of the pressing member 316 and the pair of leg members 317a and 317b, and fig. 19 (c) is a front view of the pressing member 316 and the pair of leg members 317a and 317b. The pressing member 316 and the pair of leg members 317a and 317b are the following conductive pressing members: the lower end of the pressing portion contacts the 3 rd contact of the switch 310 and supports the pressing surface, and the pressing portion presses the switch 310 when the pressing surface is pressed.

The pressing member 316 and the pair of leg members 317a and 317b are integrally formed of a material having high spring properties such as phosphor bronze, plated with a plating layer such as gold, silver, palladium, or the like having high electrical conductivity, as in the pressing member 216 and the pair of leg members 217a and 217 b. The pressing member 316 has a pressing surface 316a disposed above the pressing portion 315b of the switch 310. The pressing member 316 has a rectangular planar shape, and a pair of leg members 317a and 317b are connected to a pair of diagonal members.

The leg member 317a has a 1 st extension 331, a 2 nd extension 332, and a 3 rd extension 333, and moves the pressing member 316 toward the pressing portion 315b together with the leg member 317b as the pressing surface 316a is pressed. The 1 st extending portion 331 has one end connected to the pressing member 316, and extends from the pressing portion 315b side toward the end side in the longitudinal direction of the switch substrate 311 in parallel with the extending direction of the surface of the switch substrate 311. The end portion in the longitudinal direction, to which the 1 st extension 331 extends, is arranged to overlap with the end portion of the switch substrate 311.

The 2 nd extension 332 extends from the end portion side of the switch substrate 311 toward the pressing portion 315b side while being bent. One end of the 2 nd extension 332 is connected to the other end of the 3 rd extension 333, and the other end of the 2 nd extension 332 is disposed outside the switch substrate 311. The 2 nd extension 332 has a substantially U-shaped recess 332a arranged to contact the 3 rd contact 323a, and the bottom surface of the recess 332a is bonded to the 3 rd contact 323a with an adhesive or the like. The tip of the 2 nd extension 332 is electrically connected to the substrate 108 by solder.

The width of the leg portion of the recess 332a extending toward the switch substrate 311 is narrower than the width of the bottom surface of the recess 332a and the other portion of the 2 nd extension 332. Since the width of the leg portion of the recess 332a extending toward the switch substrate 311 is narrow, more adhesive can be filled into the 2 nd through hole 312b when the bottom surface of the recess 332a is bonded to the 3 rd contact 323a. By fixing the concave portion 332a with an adhesive or the like, the pressing member 316 is integrated with the switch 310, so that the occurrence of misalignment between the pressing member 315 and the switch 310 is prevented, and the concave portion 332a serves as a fulcrum when stress is applied to the pressing member 315. In addition, when the tip 332b of the 2 nd extension 332 is soldered, since the recess 332a is fixed by an adhesive or the like, soldering is easy, and noise generated in the electric signal flowing through the pressing member 316 and the pair of leg members 317a and 317b is reduced.

The 2 nd extension 332 further extends outward from the recess 332a, and extends outward from the switch substrate 311 in the direction of the switch substrate 311. The 2 nd extension 332 has an electrode at the tip 332b, and is mounted on the substrate of the electronic device on which the electronic component 3 is mounted on the outside.

The 3 rd extension 333 extends along one short side of the switch substrate 311 in the extending direction of the surface of the switch substrate 311. The 3 rd extension 333 is connected to the 1 st extension 331 at one end and to the 2 nd extension 332 at the other end, thereby connecting the 1 st extension 331 and the 2 nd extension 332. The 3 rd extension 333 forms an inverted S-shaped planar shape together with the 2 nd extension 332.

The leg member 317b has a 1 st extension 336, a 2 nd extension 337, and a 3 rd extension 338, and moves the pressing member 316 toward the pressing portion 315b together with the leg member 317a as the pressing surface 316a is pressed. The 1 st extending portion 336 has one end connected to the pressing member 316, and extends from the pressing portion 315b side toward the end portion side of the switch substrate 311 in parallel with the extending direction of the surface of the switch substrate 311. The end portion in the longitudinal direction, to which the 1 st extension portion 336 extends, is arranged to overlap with the end portion of the switch substrate 311.

The 2 nd extension portion 337 extends from the end portion side of the switch substrate 311 toward the pressing portion 315b side while being bent. One end of the 2 nd extension portion 337 is connected to the other end of the 3 rd extension portion 338, and the other end of the 2 nd extension portion 337 is disposed outside the switch substrate 311. The 2 nd extension portion 337 has a substantially U-shaped recess 337a arranged to contact the 3 rd contact 323b, and the bottom surface of the recess 337a is bonded to the 3 rd contact 323a with an adhesive. The tip 337b of the 2 nd extension 337 is electrically connected to the substrate 108 by solder.

The width of the leg portion of the recess 337a extending toward the switch substrate 311 is narrower than the width of the bottom surface of the recess 337a and the other portion of the 2 nd extension 337. Since the leg portion of the recess 332a extending toward the switch substrate 311 has a narrow width, more adhesive can be filled into the 3 rd through hole 312c when the bottom surface of the recess 337a is bonded to the 3 rd contact 323 b.

The 2 nd extension portion 337 extends further outward from the recess portion 337a, and extends outward from the switch substrate 311 in the direction of the switch substrate 311. The 2 nd extension portion 337 has an electrode at a distal end 337b, and is mounted on the substrate of the electronic device on which the electronic component 3 is mounted on the outside.

The 3 rd extension 338 extends along one short side of the switch substrate 311 in the extending direction of the surface of the switch substrate 311. The 3 rd extension 338 is connected to the 1 st extension 336 at one end and to the 2 nd extension 337 at the other end, thereby connecting the 1 st extension 336 and the 2 nd extension 337. The 3 rd extension 338 forms an inverted S-shaped planar shape together with the 2 nd extension 337.

Each of the pair of leg members 317a and 317b has a point-symmetrical shape with respect to the center point of the lower surface 316 a.

The pair of leg members 317a and 317b as elastic members support the pressing member 316 diagonally, whereby the pressing member 316 descends toward the switch 310 as the pressing surface 316a is pressed.

The electronic component 3 is fixed by joining the bottom surfaces of the recess portions 332a and 337a of the 2 nd extension portions 332 and 337 of the pair of leg members 317a and 317b to the 3 rd contacts 323a and 323b of the switch 310.

(effects of the electronic component according to embodiment 3)

In the electronic component 3, since the pair of leg members 317a and 317b each fix the recess 332a and 337a to the 3 rd contacts 323a and 323b with an adhesive, stress applied to the tips 332b and 337b of the 2 nd extensions 332 and 337 electrically connected to the substrate 108 with solder can be reduced.

In the electronic component 3, the pair of leg members 317a and 317b extend to the end of the switch board 311, and have an inverted S-shape, so that the length can be made as long as possible, and stress generated by the pressing down of the pressing down surface 316a can be dispersed.

In the electronic component 3, since the pair of leg members 317a and 317b are fixed to the 3 rd contacts 323a and 323b by the recesses 332a and 337a, stress applied to the tips 332b and 337b of the 2 nd extensions 332 and 337 fixed to the substrate by soldering can be reduced.

The foot member 417a has a 1 st extension portion 431, a 2 nd extension portion 432, and a 3 rd extension portion 433 arranged so as to surround the pressing surface 416a, and moves the pressing member 416 toward the pressing portion 415b together with the foot member 417b as the pressing surface 416a is pressed. One end of the 1 st extension 431 is connected to 1 corner of the pressing member 416. The 1 st extending portion 431 extends from the pressing portion 415b side toward the end portion side in the long side direction of the switch substrate 411 in parallel with the short side of the switch substrate 411 from one end of the pressing surface 416a toward the other end of the pressing surface 416a along the side surface of the pressing surface 416 a. The end of the 1 st extension 431 overlaps the end of the switch substrate 411.

The 2 nd extension 432 has one end connected to the 1 st extension 431 and the other end connected to the 3 rd extension 433, and extends along the side of the other end of the pressing surface 416 a. The 2 nd extension 432 is disposed so as to cover the side extending in the longitudinal direction of the switch substrate 411. The 3 rd extension 433 has one end connected to the 2 nd extension 432 and the other end connected to the 3 rd contact 423a. The 3 rd extending portion 433 extends while being inclined along a side opposite to the side along which the 1 st extending portion 431 is pressed. The leg member 417a is disposed between the 3 rd extension 433 and the pressing surface 416 a.

The foot member 417b has a 1 st extension part 436, a 2 nd extension part 437, and a 3 rd extension part 438 arranged so as to surround the pressing surface 416a, and moves the pressing member 416 toward the pressing part 415b together with the foot member 417a as the pressing surface 416a is pressed. One end of the 1 st extension 436 is connected to the opposite corner of the depressing member 416 that connects the corners of the 1 st extension 431. The 1 st extending portion 436 extends from the pressing portion 415b side toward the end portion side in the long side direction of the switch substrate 411 in parallel with the short side of the switch substrate 411 from one end of the pressing surface 416a toward the other end of the pressing surface 416a along the side surface of the pressing surface 416 a. The end of the 1 st extension 436 overlaps the end of the switch substrate 411.

The 2 nd extension 437 has one end connected to the 1 st extension 436 and the other end connected to the 3 rd extension 438, and extends along the side of the other end of the push-down surface 416 a. The 2 nd extension 437 is disposed so as to cover the side extending in the longitudinal direction of the switch substrate 411. The 3 rd extension 438 is connected to the 2 nd extension 437 at one end and to the 3 rd contact 423b at the other end. The 3 rd extending portion 438 extends while being inclined along the side opposite to the side along which the 1 st extending portion 436 is pressed down. The 1 st extension 431 of the leg member 417a is disposed between the 3 rd extension 438 and the pressing surface 416 a.

Each of the pair of leg members 417a and 417b has a point-symmetrical shape with respect to the center point of the lower surface 416 a.

The pair of leg members 417a and 417b as elastic members support the pressing member 416 diagonally, whereby the pressing member 416 descends toward the switch 410 as the pressing surface 416a is pressed.

The electronic component 4 is fixed by soldering the tips of the 3 rd extending portions 433 and 438 of the pair of leg members 417a and 417b to the 3 rd contacts 423a and 423b of the switch 410.

(effects of the electronic component according to embodiment 4)

In the electronic component 4, the pair of leg members 417a and 417b are each disposed so as to surround the pressing surface 416a, whereby the pressing distance of the pressing surface 416a can be lengthened without increasing the area of the substrate.

In the electronic component 4, since the pair of leg members 417a and 417b extend to positions overlapping with the end portions of the switch board 411, the pressing distance of the pressing surface 416a can be further increased.

In the electronic component 4, the pair of leg members 417a and 417b are disposed in the 1 st notch 412b and the 2 nd notch 412c which are formed by opening along the short side of the switch board 411, and thus soldering operation with the 3 rd contacts 423a and 423b is easier.

Fig. 24 (a) is a perspective view of the electronic component according to embodiment 5, fig. 24 (B) is a cross-sectional view taken along line B-B of fig. 24 (a), and fig. 25 is an exploded perspective view of the electronic component shown in fig. 24 (a).

The electronic component 5 has a switch 510, and a support member 516 and an elastic member 517 that are integrally formed, and can be mounted on the electronic device 100, as in the electronic components 1 to 4. The electronic component 5 is turned on by the pressing of the operation member 102 by the operator, and acquires the living body information such as ECG by acquiring the current from the operator by the operator touching the operation member 102.

The switch 510 includes a switch substrate 511, a frame 512, a movable contact 513, a pushing member 514, and a sealing sheet 515, and is turned on when the upper surface is pushed down, and is turned off when the upper surface is no longer pushed down.

The 1 st contact 521, the 2 nd contact 522, and the 3 rd contacts 523a and 523b are disposed on the front surface 520a of the substrate 520, and the 1 st back electrode 524, the 2 nd back electrode 525, and the 3 rd back electrodes 526a and 526b are disposed on the back surface 520b of the substrate 520.

The 1 st contact 521 is made of a metal foil such as copper, and is a conductor disposed in the center of the surface of the substrate 520. The 2 nd contact 522 is formed of a metal foil such as copper, and is a conductor having a substantially U-shaped planar shape disposed on the surface of the substrate 520 so as to surround the 1 st contact 521. The 2 nd contact 522 is arranged so that the outer edge of the movable contact 513 contacts, and the 1 st contact 521 contacts the top of the movable contact 513 when the movable contact 513 performs a tilting operation.

The 3 rd contacts 523a and 523b are formed of a metal foil such as copper, and are a pair of rectangular conductors of the substrate 520 arranged near the ends of the surface of the substrate 520 in the longitudinal direction. The 3 rd contacts 523a and 523b are arranged to be connectable to the lower end of the elastic member 517 by solder.

The 1 st back electrode 524 is electrically connected to the 1 st contact 521 via a conductor filled in the via hole 528 a. The 1 st back electrode 524 is formed on the inner wall of the recess 527a and is electrically connected to a connection electrode soldered when the electronic component 5 is mounted on the substrate 108.

The 2 nd back electrode 525 is electrically connected to the 2 nd contact 522 via a conductor filled in the via hole 528 b. The 2 nd back electrode 525 is formed on the inner wall of the recess 527b and electrically connected to the connection electrode soldered when the electronic component 5 is mounted on the substrate 108.

The 3 rd back electrodes 526a and 526b are electrically connected to the 3 rd contacts 523a and 523b via conductors filled in the vias 528c and 528 d. The 3 rd back electrodes 526a and 526b are formed on the inner walls of the concave portions 527c and 527d, and are electrically connected to connection electrodes soldered when the electronic component 5 is mounted on the substrate 108.

The frame 512 is made of a resin material such as polyimide, and has a frame-like outer shape surrounding the 2 nd contact 522. The frame 512 has a through hole 512a. The through hole 512a forms a housing portion in which the 1 st contact 521, the 2 nd contact 522, the movable contact 513, and the pressing piece 514 are disposed together with the surface 520a of the switch substrate 511.

The movable contact 513 includes a 1 st movable contact 513a, a 2 nd movable contact 513b, a 3 rd movable contact 513c, and a 4 th movable contact 513d. The 1 st movable contact 513a, the 2 nd movable contact 513b, the 3 rd movable contact 513c, and the 4 th movable contact 513d are each formed of an elastic conductive member such as stainless steel or copper, which is thin and formed in a dome shape. The 1 st movable contact 513a, the 2 nd movable contact 513b, the 3 rd movable contact 513c, and the 4 th movable contact 513d are stacked so as to be insulated from the 1 st contact 521 and to be electrically connected to the 2 nd contact 522. The 1 st movable contact 513a, the 2 nd movable contact 513b, the 3 rd movable contact 513c, and the 4 th movable contact 513d are formed by cutting a convex dome-shaped plate spring member so as to have a grass bag shape with opposing sides.

The pushing piece 514 is made of a resin material such as polyimide having a cylindrical shape, and is a pressing member disposed above the center portion of the 4 th movable contact 513d, as in the pushing piece 14. By disposing the pushing piece 514, operability of the pressing operation of the switch 510 is improved.

The sealing sheet 515 is a sheet made of a flexible synthetic resin such as polyimide, and protects the 1 st contact 521, the 2 nd contact 522, the movable contact 513, and the pushing member 514, which are housed in a housing portion formed by the surface 520a of the switch board 511 and the through hole 512a of the frame 512. The sealing sheet 515 is fixed to the frame 512 by being adhered to the surface of the frame 512 so as to cover the storage portion formed by the switch board 511 and the frame 512.

The sealing piece 515 has an inclined portion 515a, a pressing portion 515b, and an outer edge portion 515c. The inclined portion 515a is inclined so as to cover the outer edges of the 1 st movable contact 513a, the 2 nd movable contact 513b, the 3 rd movable contact 513c, and the 4 th movable contact 513d protruding from the through hole 512 a. The pressing portion 515b is a top portion surrounded by the inclined portion 515a, and forms a plane so as to cover the pressing piece 514. The outer edge 515c is bonded to the surface of the frame 512.

The circuit configuration of the switch 510 is the same as that of the switch 10, and therefore, a detailed description thereof is omitted here.

Fig. 27 (a) is a top view of the support member 516 and the elastic member 517, fig. 27 (b) is a side view of the support member 516 and the elastic member 517, and fig. 27 (c) is a front view of the support member 516 and the elastic member 517. The support member 516 and the elastic member 517 are the following conductive pressing members: the lower end of the pressing portion contacts the 3 rd contact of the switch 510, supports the pressing surface, and presses the switch 510 by the pressing portion when the pressing surface is pressed.

The support member 516 and the elastic member 517 are integrally formed of a material having high spring properties such as phosphor bronze, which is plated with a plating layer such as gold, silver, or palladium having high electrical conductivity, as with the pressing member 216 and the pair of leg members 217a and 217 b. The integrally formed support member 516 and elastic member 517 are disposed so as to cover the pressing portion 515b, and are electrically connected to the 3 rd contacts 523a and 523b. The support member 516 and the elastic member 517 have axisymmetric shapes about a straight line passing through the center point of the pressing portion 517a and parallel to the longitudinal direction of the support member.

The support member 516 has a base 516a, a 1 st support 516b, and a 2 nd support 516c. The base 516a has a frame-like or rectangular shape surrounding the pressing portion 515b of the elastic member 517, and the elastic member 517 is connected to the inner wall of one short side. The 1 st support portion 516b and the 2 nd support portion 516c are connected to both ends of the base portion 516a, which is a pair of short sides of the base portion 516a, and support the base portion 516a and are connected to each of the 3 rd contacts 523a and 523 b. The 1 st support portion 516b and the 2 nd support portion 516c have a concave portion formed at the center. By forming the recess in the center of the bottom surfaces of the 1 st support portion 516b and the 2 nd support portion 516c, the bonding area increases and the bonding strength increases when the 1 st support portion 516b and the 2 nd support portion 516c are soldered to the 3 rd contacts 523a and 523 b.

The elastic member 517 has a pressing portion 517a and a leg portion 517b. The pressing portion 517a has a rectangular planar shape and is disposed in a substantially central portion of the opening surrounded by the base portion 516 a. One end of the leg 517b is connected to one side of the depressed portion 517a, and the other end is connected to one short side of the base 516 a. The elastic member 517 moves the pressing portion 517a toward the pressing portion 515b as the pressing portion 517a is pressed by the operating member 102. The leg 517b has a width smaller than the width of the pressing portion 517a, but in the electronic component of the embodiment, the width of the leg may be the same as the width of the pressing portion.

The electronic component 5 is manufactured by soldering the tips of the 1 st support portion 516b and the 2 nd support portion 516c of the support member 516 to the 3 rd contacts 523a and 523b of the switch 510.

(effects of the electronic component according to embodiment 5)

The electronic component 5 is provided with a current path by a conductive support member 516 and an elastic member 517 disposed above the switch 510. Since the current circuit is formed via the conductive support member 516 and the elastic member 517 disposed above the switch 510, the electronic component 5 can form a current path that is less likely to deteriorate over time regardless of the pressing operation for the switch.

In addition, in the electronic component 5, the support member 516 and the elastic member 517 are integrally molded, so the number of components is reduced, and thereby the manufacturing cost can be reduced.

In the electronic component 5, the 3 rd contacts 523a and 523b are disposed in the region where the frame 512 is not disposed, and therefore soldering between the 1 st support portion 516b and the 2 nd support portion 516c of the support member 516 and the 3 rd contacts 523a and 523b of the switch board 511 is easier.

(constitution and function of electronic component of embodiment 6)

The elastic member 617 has a pressing portion 617a, a 1 st leg 617b, and a 2 nd leg 617c, and has a substantially U-shaped planar shape. The pressing portion 617a is connected to each of the 1 st leg 617b and the 2 nd leg 617c at both ends of the long side, and is disposed at a substantially central portion of the opening surrounded by the base 616 a. The pressing portion 617a has a protrusion protruding in the extending direction of the 1 st leg 617b and the 2 nd leg 617 c. The other ends of the 1 st leg 617b and the 2 nd leg 617c are connected to one long side of the base 616 a. The elastic member 617 moves the pressing portion 617a toward the pressing portion 515b as the pressing portion 617a is pressed by the operation member 102.

The electronic component 6 is fixed by soldering the tips of the 1 st support portion 616b and the 2 nd support portion 616c of the support member 616 to the 3 rd contacts 523a and 523b of the switch 610.

(constitution and function of electronic component of embodiment 7)

Fig. 31 is a perspective view of the electronic component of embodiment 7, and fig. 32 is an exploded perspective view of the electronic component shown in fig. 31.

The electronic component 7 has a support member 716 and an elastic member 717 instead of the support member 516 and the elastic member 517, unlike the electronic component 5. The components and functions of the electronic component 7 other than the support member 716 and the elastic member 717 are the same as those of the electronic component 5 denoted by the same reference numerals, and therefore detailed description thereof will be omitted here.

The electronic component 7 can be mounted on the electronic device 100, as in the electronic components 1 to 6. The electronic component 7 is turned on by the pressing of the operation member 102 by the operator of the electronic device 100, and acquires the living body information such as ECG by acquiring the current from the operator by the operator touching the operation member 102.

Fig. 33 (a) is a top view of the support member 716 and the elastic member 717, fig. 33 (b) is a side view of the support member 716 and the elastic member 717, and fig. 33 (c) is a front view of the support member 716 and the elastic member 717. The supporting member 716 and the elastic member 717 are the following conductive pressing members: the lower end of the pressing portion contacts the 3 rd contact of the switch 510, supports the pressing surface, and presses the switch 510 by the pressing portion when the pressing surface is pressed.

The support member 716 and the elastic member 717 are formed of a material having high spring properties such as phosphor bronze, plated with a plating layer such as gold, silver, palladium, or the like having high electrical conductivity, as with the pressing member 216 and the pair of leg members 217a and 217b, and are molded as separate members. The support member 716 and the elastic member 717 are disposed so as to cover the pressing portion 15b, and are electrically connected to the 3 rd contacts 23a and 23b.

The thickness of the elastic member 717 is thinner than the thickness of the supporting member 716.

(effects of the electronic component according to embodiment 7)

In the electronic component 7, the support member 716 and the elastic member 717 are formed as different units, and therefore, the load of the elastic member 717 can be reduced and the click feeling can be improved by making the thickness of the elastic member 717 thinner than the thickness of the support member 716.

In the electronic component 7, the support member 716 and the elastic member 717 are formed as separate units, and therefore can be formed of materials corresponding to the functions of the support member 716 and the elastic member 717.

(modification of electronic component of embodiment)

The electronic components 1 to 7 have switches as push-button switches, but the electronic components of the embodiment may have switches other than push-button switches such as a micro switch and a dial switch, as long as they have a 3 rd contact capable of forming a current path with an operator.

The electronic component 1 includes the elastic member 16, and the elastic member 16 includes a pair of support portions 35a and 35b and leg portions 31a and 31b sandwiched between the pair of support portions 35a and 35b, but the electronic component of the embodiment may include an elastic member having conductivity different from the shape of the elastic member 16. For example, the electronic component of the embodiment may have a coil spring formed of a conductive material as an elastic member disposed between the switch 10 and the pressing member 17.

In the electronic component 1, the pair of support portions 35a and 35b of the elastic member 16 are arranged so as to extend parallel to the longitudinal direction of the pressing member 17, but in the electronic component of the embodiment, the pair of support portions of the elastic member may extend in the extending direction of the pressing member.

In the electronic component 1, the pair of support portions 35a and 35b are connected by the top portion 33, but in the electronic component of the embodiment, any portion of the elastic portion having a convex shape toward the pressing member may be connected.

In the electronic component 1, the pressing member 17 has a rectangular planar shape with notches formed at four corners, but in the electronic component of the embodiment, the pressing member may have a planar shape other than rectangular, such as a circular shape and a triangular shape. In the electronic component according to the embodiment, the pressing member may not have a notch at the corner.

The electronic device 100 on which the electronic components 1 to 7 are mounted is a smart watch, but the electronic device of the embodiment may be a wearable device other than a wrist-band type, a ring type, a speaker type, or the like. The electronic device according to the embodiment may be a mobile terminal other than a wearable device such as a smart phone, or may be a stationary electronic device such as a weight scale or a blood pressure meter.

In the electronic parts 2 to 4, the pair of leg members have a point-symmetrical shape with respect to the center point of the lower surface, but in the electronic part of the embodiment, the pair of leg members may have a line-symmetrical shape with respect to the lower surface, that is, with respect to a straight line passing through the center point of the lower surface.

Fig. 34 is a perspective view of an electronic component 8 according to modification 1.

The electronic component 8 has a pressing member 816 and a pair of leg members 817a and 817b instead of the pressing member 316 and the pair of leg members 317a and 317b, which are different from the electronic component 3. The components of the electronic component 8 other than the pressing member 816 and the pair of leg members 817a and 817b are identical in configuration and function to those of the electronic component 3 denoted by the same reference numerals, and therefore detailed description thereof is omitted here.

The pressing member 816 has a pressing surface 816a, and a pair of leg members 817a and 817b are connected to both ends of a side extending in the longitudinal direction of the switch 310.

The pair of leg members 817a and 817b have a shape symmetrical about a straight line passing through the center point of the pressing surface 816 a. The pair of leg members 817a and 817b are each line symmetrical with respect to the following reference, not point symmetrical, and have the same configuration as the pair of leg members 317a and 317b, so that detailed description thereof is omitted here.

In the electronic components 1 to 7, the protruding portion is not formed on the back surface of the pressing member or the like arranged so as to cover the upper surface of the switch and the frame material, but in the electronic component of the embodiment, the protruding portion may be formed on the back surface of the member arranged so as to cover the upper surface of the switch and the frame material. In the electronic component according to the embodiment, the movement of the member arranged so as to cover the upper surface of the frame material and the frame material in the switching direction is restricted by forming the protruding portion at any one of the rear surfaces of the member arranged so as to cover the upper surface of the frame material and the frame material. The electronic component according to the embodiment can prevent the movable contact from being broken due to excessive pressing force applied to the movable contact protruding from the through hole of the frame member by dropping or the like of the electronic device by restricting movement of the member arranged to cover the upper surface of the frame member and the frame member in the opening/closing direction.

Fig. 35 (a) is a perspective view of an electronic component according to modification 2, and fig. 35 (B) is a cross-sectional view taken along line B-B of fig. 35 (a).

The electronic component 1a has an elastic member 46 instead of the elastic member 16, which is different from the electronic component 1. The components and functions of the electronic component 1a other than the elastic member 46 are the same as those of the electronic component 1 denoted by the same reference numeral, and therefore detailed description thereof is omitted here.

The pair of concave portions 66a and 66b each have a T-shaped planar shape and are formed by drawing.

The electronic component 1c is configured such that the rigidity of the elastic member 66 is improved by forming the pair of recesses 66a and 66b in the elastic member 66 by drawing, and the pressing force applied to the switch 10 is reduced due to bending of the elastic member 66 when pressed down. In the electronic component 1c, since the rigidity of the elastic member 66 is improved, the pressing member 17 is omitted, and the manufacturing cost can be reduced compared with the electronic component 1.

Fig. 44 (a) is a perspective view of an electronic component according to modification 11, and fig. 44 (B) is a cross-sectional view taken along line B-B of fig. 44 (a).

By forming the recess 266a in the pressing member 266 by drawing, the electronic component 2c can increase the rigidity of the pressing member 266, and can reduce the risk of a lowering of the pressing force applied to the switch 210 due to bending of the pressing member 266 when pressed.

In the electronic components 1 to 7, the switch has a single columnar presser, but in the electronic component of the embodiment, the switch may have a presser having a shape other than columnar, or may have a plurality of pressers.

Fig. 45 (a) is a perspective view of the switch according to modification 1, and fig. 45 (b) is a cross-sectional view taken along line C-C of fig. 45 (a).

The switch 10a has a pushing member 14a instead of the pushing member 14, which is different from the switch 10. The components and functions of the switch 10a other than the pushing member 14a are the same as those of the switch 10 denoted by the same reference numerals, and therefore detailed description thereof is omitted here.

The pushing member 14a is formed of a resin material such as polyimide, and has a lower portion 14b and an upper portion 14c, as in the pushing member 14. The lower portion 14b has a cylindrical shape having the same diameter as the pressing tool 14, and is disposed above the center portion of the 3 rd movable contact 13 c. The upper portion 14c has a cylindrical shape having a diameter longer than that of the lower portion 14b, and is disposed so that the rear surface contacts the upper surface of the lower portion 14b and the center coincides with the center of the lower portion 14 b. Since the diameter of the upper portion 14c is longer than the diameter of the lower portion 14b, the pushing member 14a has a T-shaped cross-sectional shape.

The diameter of the upper portion 14c is longer than the diameter of the bottom surface of the stem 122 of the operating member 102, which is a pressing member that presses the pressing member 17 disposed above the switch 10a.

In the switch 10a, since the diameter of the upper portion 14c is longer than the diameter of the pressing member that presses the pressing surface of the pressing member 17, even when the switch 10a is pressed in a state in which the pressing member 17 is inclined, the width of the upper portion 14c is larger than the width of the lower portion 14b, so that the inclination of the pressing member 17 can be relaxed by the gap between the upper portion 14c and the lower portion 14b, and an appropriate pressing force can be transmitted to the switch 10a. In the switch 10a, even when the pressing member 17 is deformed to press the switch 10a, there is less possibility that the movable contact 13 is damaged by pressing a portion other than the upper portion 14c.

Fig. 46 (a) is a perspective view of the switch according to modification 2, and fig. 46 (b) is a cross-sectional view taken along line C-C of fig. 46 (a).

The switch 10b has a pushing member 14d in addition to the pushing member 14, which is different from the switch 10. The components and functions of the switch 10b other than the pushing member 14d are the same as those of the switch 10 denoted by the same reference numerals, and therefore detailed description thereof will be omitted here.

The pushing member 14d is formed of a resin material such as polyimide as with the pushing member 14, and has a cylindrical shape having a diameter longer than that of the pushing member 14 as with the upper portion 14 c. The pushing piece 14d is disposed on the pushing piece 14 with a seal piece 15 interposed therebetween so that the center coincides with the center of the pushing piece 14. The diameter of the pushing piece 14d is longer than the diameter of the bottom surface of the stem 122 of the operation member 102, which is a pressing member for pressing the lower surface of the pressing member 17 disposed above the switch 10b as shown in fig. 2, as the diameter of the upper portion 14 c. In the switch 10b, the pressing member 14 has a cylindrical shape, is disposed at a lower portion of the top of the movable contact, and the pressing member 14d has a cylindrical shape having a diameter longer than that of the lower portion and is disposed at an upper portion above the lower portion.

In the switch 10b, since the diameter of the pushing piece 14d is longer than the diameter of the bottom surface of the stem 122 of the operation member 102, which is a pressing member that presses the pressing member 17 disposed above the switch 10a, even when the switch 10b is pressed in a state in which the pressing member 17 is inclined, an appropriate pressing force can be transmitted to the switch 10a. In the switch 10b, even when the pressing member 17 is deformed to press the switch 10b, the movable contact 13 is less likely to be damaged by the pressing of the portion other than the pressing piece 14 d.

The electronic components 1 to 7 are mounted on the board 108 as an FPC, but the electronic components of the embodiment may be mounted on a rigid board or a fimbrane board, or may be mounted on a base that electrically connects the electronic components and the board.

Fig. 47 (a) is a perspective view of an electronic component according to modification 12, fig. 47 (B) is an exploded sectional view of the electronic component shown in fig. 47 (a), and fig. 47 (c) is a sectional view taken along line B-B of fig. 47 (a).

The electronic component 1d has a base 130, which is different from the electronic component 1. The components and functions of the electronic component 1d other than the base 130 are the same as those of the electronic component 1 denoted by the same reference numerals, and therefore detailed description thereof is omitted here.

The base 130 is made of a resin material such as polyimide, and has a base 131, a 1 st hook 132, and a 2 nd hook 133. The base 131 has a substantially rectangular planar shape, and forms a recess 134 for accommodating the switch 10, the elastic member 16, and the pressing member 17.

The 1 st hook 132 and the 2 nd hook 133 are arranged to stand up from the central portions of the pair of short sides of the base 131. The 1 st hook 132 and the 2 nd hook 133 are disposed so that the engagement portion formed at the top portion faces outward.

The electronic component 1d is mounted on the substrate 135. The board 135 is a hedge flexible board, and the power supply element 136 is mounted together with the electronic component 1 d.

By providing the electronic component 1d with the base 130 having the 1 st hook 132 and the 2 nd hook 133, workability in the assembly process of loading the electronic component 1d into the electronic device is improved.

Fig. 48 (a) is a perspective view of an electronic component according to modification 13, fig. 48 (B) is an exploded sectional view of the electronic component shown in fig. 48 (a), and fig. 48 (c) is a sectional view taken along line B-B of fig. 48 (a).

The electronic component 1e has a base 140, which is different from the electronic component 1. Further, the electronic component 1e does not have the switch substrate 11, which is different from the electronic component 1. The components and functions of the electronic component 1e other than the base 140 are the same as those of the electronic component 1 denoted by the same reference numerals, and therefore detailed description thereof is omitted here. The electronic component 1e is mounted on the substrate 135 as is the case with the electronic component 1 d.

The base 140 has a base 141 instead of the base 131, which is different from the base 130. The structure and function of the base 140 other than the base 141 are the same as those of the base 130 denoted by the same reference numeral, and thus detailed description thereof will be omitted here.

The base 141 has a substantially rectangular planar shape, and has a recess 144 formed therein for accommodating the switch, the elastic member 16, and the pressing member 17. Contacts corresponding to the 1 st contact 21, the 2 nd contact 22, and the 3 rd contacts 23a and 23b are arranged on the bottom surface of the recess 144.

Since the electronic component 1e does not have the switch substrate 11, the manufacturing cost is reduced as compared with the electronic component 1d.

Fig. 49 (a) is a perspective view of an electronic component according to modification 14, and fig. 49 (B) is a cross-sectional view taken along line B-B of fig. 49 (a). Fig. 49 (c) is a perspective view showing a state in which the electronic component shown in fig. 49 (a) is pressed by the pressing member, and fig. 49 (d) is a sectional view taken along line B-B of fig. 49 (c).

The electronic component 1f has a base 150 instead of the base 130, which is different from the electronic component 1d. The components and functions of the electronic component 1f other than the base 150 are the same as those of the electronic component 1d denoted by the same reference numerals, and therefore detailed description thereof is omitted here. The electronic component 1f is mounted on the substrate 135 as is the case with the electronic component 1d.

The base 150 is different from the base 130 in that a pair of protrusions 151 are provided on a pair of long sides of the base 131. The structure and function of the base 150 other than the pair of protruding portions 151 are the same as those of the base 130 denoted by the same reference numeral, and therefore detailed description thereof is omitted here.

The pair of protrusions 151 are higher than the movable contact 13 and lower than the surface of the pressing member 17, and are arranged so as to be able to contact the bottom surface of the pressing member 152 that presses the lower surface of the pressing member 17.

Since the electronic component 1f has the pair of protruding portions 151 arranged so as to be able to contact the bottom surface of the pressing member 152, it is possible to prevent the movable contact 13 from being broken due to excessive pressing force applied to the movable contact 13 by dropping or the like of the electronic device.

In the electronic components 2 to 4, the pressing member and the pair of leg members are integrally formed, but in the electronic component of the embodiment, the pressing member and the pair of leg members may be formed separately and connected by the connecting member to be integrated.

In the electronic components 2 and 4, the bottom surfaces of the concave portions of the leg members are joined to the joint portions of the switch board by means of an adhesive, but in the electronic component of the embodiment, the bottom surfaces of the concave portions of the leg members may be joined to the joint portions by welding.

The electronic components 1 to 7 have the pushing members arranged on the top of the movable contact, but the electronic components of the embodiment may not have the pushing members. In the electronic component according to the embodiment, when the pushing member is not provided, the protruding portion is formed at the center portion of the rear surface of the pressing member.

In the electronic components 1 to 7, the switch has a plurality of movable contacts, but in the electronic component of the embodiment, the switch may have a single movable contact.

In the electronic components 1 to 7, both of the pair of 3 rd contacts arranged on the switch surface are fixed to the conductive pressing member, but in the electronic component of the embodiment, at least one of the pair of 3 rd contacts may be fixed to the conductive pressing member.

In the electronic components 4 and 5, the support member and the elastic member are integrally formed, but in the electronic component of the embodiment, the support member and the elastic member may be formed separately and connected by the connecting member to be integrated.

(comparison of maximum stress)

Fig. 50 (a) is a diagram showing a distribution of stress generated when the electronic component 1 is pressed, fig. 50 (b) is a diagram showing a distribution of stress generated when the electronic component 2 is pressed, and fig. 50 (c) is a diagram showing a distribution of stress generated when the electronic component 4 is pressed.

The stress distribution shown in (a) to (50 (c) of fig. 50 was obtained by pressing the lower surfaces of the electronic components 1, 2, and 4 with a pressing force of 15N through simulation using the software Jvision, manufactured by JSOL corporation.

In the electronic component 1, the maximum value of the stress generated in the elastic member 16 was 183Mpa, and in the electronic component 2, the maximum value of the stress generated in the leg members 217a and 217b was 147Mpa. In the electronic component 2, the 2 nd extending portions 233 and 238 of the leg members 217a and 217b extend from the end portion side of the substrate 211 toward the pressing portion 215 side, so that the length of the portion bent by pressing is longer than that of the elastic member 16 of the electronic component 1. Since the electronic component 2 is longer than the electronic component 1 in the length of the portion bent by the pressing, the stress generated when the electronic component is pressed is dispersed, and thus the maximum stress can be reduced as compared with the electronic component 1.

In the electronic component 4, the maximum value of the stress generated in the leg members 417a and 417b is 175Mpa, and when the length of the leg members of the electronic component 4 is changed so as to be the same as the length of the leg members 217a and 217b of the electronic component 2, the maximum value of the stress generated in the leg members is 110Mpa. In the electronic component 4, the leg members 417a and 417b are arranged so as to surround the pressing surface 416a, whereby the length of the portion bent by the pressing is longer than the leg members 217a and 217b of the electronic component 2. Since the length of the portion of the electronic component 4 bent by the pressing is longer than the electronic component 2, the stress generated when the electronic component is pressed is dispersed, and thus the maximum stress can be further reduced as compared with the electronic component 2.

(comparison of click through Rate)

Fig. 51 (a) is a diagram showing load characteristics of the electronic components 1, 2, and 4 and the switch 10, and fig. 51 (b) is a diagram showing a ratio of click rates of the electronic components 1, 2, and 4 when the click rate of the switch 10 is set to 100%. In fig. 51 (a), the horizontal axis represents the downward displacement amount accompanying the pressing, and the vertical axis represents the pressing force that is the load applied. Further, a waveform W101 represents the load characteristic of the light emitting device 1, a waveform W102 represents the load characteristic of the light emitting device 2, a waveform W103 represents the load characteristic of the light emitting device 4, and a waveform W104 represents the load characteristic of the switch 10.

The load characteristics of the light emitting device 1 are greatly different from those of the switch 10. On the other hand, the load characteristics of the light emitting devices 2 and 4 are similar to those of the switch 10.

The click rate of the electronic component 1 was 74% of the click rate of the switch 10, the click rate of the electronic component 2 was 93% of the click rate of the switch 10, and the click rate of the electronic component 4 was 88% of the click rate of the switch 10. The click rate of the electronic component 2 is preferably lower than the click rate of the electronic component 4, but the value is close to 90% of the click rate of the switch 10.

The electronic component 2 has a rectangular planar shape with a long side length of 2 times or more the short side length because the leg portions are disposed at both ends of the pressing surface. On the other hand, the leg portion of the electronic component 4 surrounds the lower surface, and therefore has a rectangular planar shape having a length of the short side substantially equal to that of the long side. Since the long side of the electronic component 2 is extremely long, when the electronic component is disposed such that the lower surface 216a is positioned below the operation member 102 of the electronic device 100, there is a concern that interference with other electronic components disposed around the electronic component may occur, and the disposing operation may become complicated. On the other hand, since the layout of the electronic component 4 is complicated, when the electronic component is arranged such that the lower surface 216a is positioned below the operation member 102 of the electronic device 100, there is less possibility of interference with other electronic components arranged around, and the arrangement work becomes easier than that of the electronic component 2.

a switch having a 1 st contact and a 2 nd contact which are turned on when the upper surface is pressed, and a 3 rd contact exposed from the upper surface;
