[Prior art] The components of the rotary switch include a frame with a fixed contact _ II and a rotating body driving the movable contact, which is changed by rotating the rotating body; the connection between the movable contact and the fixed contact is changed. Relationship to switch the circuit used. In the past, such a switch has been used for a device's volume adjustment knob and a mode switch. The structure of a conventional rotary switch is shown in cross-section in FIG. 6. The rotating body 1 0 1 has a shaft portion 1 0 1 A and a protruding portion 101B extending along the axis of the rotating body at the center of the lower surface. A conductor having a plurality of movable contacts 102 A to C is mounted around the lower surface of the rotating body 101. 102. The movable contacts 102 A to C are made of elastic rods and the like. When the rotating body 101 is rotated, it rotates together with the rotating body and slides into contact with the corresponding fixed contacts 106 A to C. The frame body 103 is composed of a main body 104 and a cover body 105. The main body 104 has a hole 104a fitted into a protruding portion 1101B of the rotating body. A plurality of holes 104a are mounted on the inner bottom surface. The conductors 106 of the fixed contacts 106A to C (the fixed contact 1 06 c corresponding to the movable contact 10 2 C does not exist in the cross section of FIG. 6, so it is not shown). Since the convex part of the rotating body 丨 〇;! B is fitted in the hole 1 04 A, the 'rotating body 101 can be rotated without swinging. The conductor 106, which is wired on the inner bottom surface of the main body 104, extends to the outside of the housing 3, and -4-(2) 1227905 constitutes the external terminal 107. The cover body 05 is arranged so as to cover the main body 1 () 4, and it has a bearing 105a that supports the rotating body shaft 1 0A. A cover 108 is provided on the lower surface of the frame body 103 to cover the hole 104A. The internal space of the rotary switch is sealed by the shaft 1 〇 1 A of the rotating body, the housing 103 and the cover 108 to prevent intrusion of dust and moisture from the outside. A properly constructed rotary switch can change the connection state of the movable contacts 102 A to C and the fixed contacts 106 A to C when the rotating body 101 is rotated. Therefore, by properly designing the conductor 102 and the conductor 106, that is, Can constitute a variety of electric Lulu. However, in recent years, foldable mobile phones have a function of turning off the power of the display device and the like in the folded state and turning on the power of the display device and the like when the mobile phone is turned on, thereby saving power consumption. In addition, a device such as a notebook computer having a structure in which two parts are opened and closed by hinge hinges has the same function to save power consumption. In order to have such a function, a switch that detects the opening and closing of two parts is used, which has conventionally been a push button switch. The push-button switch is turned off when the rod-shaped operation part protruding from one φ-side component is pressed by another component, the power is turned off, and the switch is turned on when the operation part is released. State, turn on the power. Patent Document 1 JP-A No. 1 1-27 3 5 04 (Fig. 1 and Fig. 2) However, the conventional switch for detecting the opening and closing state adopts a push-button switch, and its protruding stick-shaped operating portion is inconvenient and cannot be turned. Mobile phones, etc. are designed to have ideal shapes, and their design is limited. Moreover, the threshold 値 (3) 1227905 depends on the length of the operation ’and cannot be designed with interest. Furthermore, in the conventional rotary switch, the protruding portion 1 〇 B of the rotating body is provided along the axis of the rotating body and extends from the lower surface of the rotating body. Therefore, the movable contacts 1 0 c must be arranged inevitably. Around below. Therefore, the rotating body 101 needs to arrange a space for a movable contact at the periphery of the lower surface, which limits the miniaturization of the rotating body 101. As a result, miniaturization of the rotary switch itself has been limited. In addition, since the bearing 105 of the lid 105 supports the shaft 1 ο 1 A of the rotating body, a certain length is required, and this has become a major factor in increasing the size of the rotary switch in the height direction. In addition, the main body 104 is provided with a hole 1 〇4 A for fitting the convex portion 1 0 1 B of the rotating body. Therefore, if the cover 1 〇8 is not provided, dust and moisture can enter the rotary switch from the outside. internal. In addition, in order to seal the internal space of the rotary switch, when a cover 108 is provided, the outer size of the rotary switch is correspondingly increased by the cover part, which is not conducive to miniaturization, and it also brings the number of parts and assembly Increase in the number of processes. Even if the 孑 L 104A does not pass through the main body 104, it is necessary to increase the thickness of the main body ι04, so that the external dimensions increase, which is not conducive to miniaturization. In this way, since the rotary switch has many problems in miniaturizing its external dimensions, it is unrealistic to use the rotary switch for a hinge hinge portion of a mobile phone or the like as a switch for detecting the opening and closing state. [Summary of the Invention] In order to solve the above problems, an object of the present invention is to provide a rotary switch with a small external size of -6-(4) 1227905. Another object of the present invention is to provide a rotary switch with excellent dustproof and waterproof performance. In addition, an object of the present invention is to provide a hinged leaf for opening and closing 2 that can be designed into an ideal shape without any restriction on the appearance design even if a switch for detecting the opening and closing state is used. 2 The structure of an object.

By adopting this structure, since a rotation guide is provided around the lower surface, a movable contact can be arranged near the center of the lower surface of the rotating body, and the diameter of the rotating body and the frame can be reduced. Furthermore, since the outer φ peripheral surface of the rotating body is overlapped with the inner peripheral surface of the frame body, the rotating body does not oscillate, and Ken g rotates stably. No additional bearing for the shaft is required, and the frame body can be reduced. Dimensions. In addition, it is not necessary to provide a hole for supporting the convex portion in the frame, so it is not necessary to provide a cover, and it is not necessary to increase the thickness of the frame. The size of the frame can be reduced, and dust and moisture can be reduced. External intrusion. Furthermore, the device adopting the rotary switch of the present invention has a structure in which two parts are connected by a hinge hinge, and the connecting part of the above two parts is arranged with a rotary switch.

In the rotation guide portion, an outer peripheral surface of the rotating body is overlapped with an inner peripheral surface of the frame body, and the rotating body is driven by a rotational movement of the hinge hinge. With this structure, the rotary switch capable of detecting the opening and closing states of the two components is arranged on the connecting portion of the two components, so the appearance design can be prevented without hindering the design of the device. Furthermore, by appropriately setting the arrangement of the movable contact and the fixed contact of the rotary switch, the switch can be turned on or off at any rotation position. Furthermore, the present invention is characterized in that: in the rotary switch or a device using the rotary switch, the movable contact is arranged on an inner bottom surface of the housing, a lower surface of the rotary body, and a rotary guide of the rotary body. In a confined space. With this structure, it is possible to prevent dust and moisture from entering the space where the movable contact and the fixed contact are arranged from the outside. The present invention is also characterized in that, in the rotary switch or a device using the rotary switch, one of the movable contacts is connected to one of the fixed contacts on an axis line of the rotating body. Due to this structure, the movable contact and the fixed contact connected on the axis can be used as a common terminal. The movable contact can also be arranged at the center of the lower -8- (6) 1227905 plane on the axis of the rotating body. Can reduce the diameter of the rotating body and the frame. The present invention is also characterized in that, in the rotary switch or a device using the rotary switch, a conductor having the movable contact is mounted on a lower surface of the rotating body by insert molding. With this structure, the rotating body can be easily formed, and the number of parts and the number of assembling processes can be reduced.

When the rotation guide 1B of the rotating body is provided around the movable contacts 2A to C, the inner bottom surface 4B of the frame 3, the lower surface of the rotation body, and the rotation guide 1B of the rotation body can be configured. The enclosed space prevents dust and moisture from entering the space where the movable and fixed contacts are installed from the outside. In addition, when the rotary guide portion 1 B of the rotating body is set to the movable contact points 2 A to C in an open state (the rotary guide portion 1 B is not opened in the upper right outer peripheral portion of FIG. 5A and is open) because Since the movable contacts 2 A to C are arranged near the outer periphery, the rotating body 1 can be further miniaturized and the effect is good. However, in this case, in order to prevent dust and moisture from invading from outside, it is desirable to improve the airtightness of the housing 3. As shown in FIG. 2, the outer peripheral surface 1 C of the rotating body may correspond to the entire outer peripheral surface of a portion housed in the housing 3 or may correspond to only a part thereof. The same applies to the inner peripheral surface of the frame 3, and may be the inner peripheral surface 4A of the main body 4 or the inner peripheral surface of the cover 5 and other components. In this way, since the rotation guide 1B of the rotating body is provided on the periphery of the lower surface, the movable contacts 2A to C can also be arranged in the center of the lower surface, and the rotating body can be miniaturized. In addition, the outer peripheral surface 1 C of the rotating body 1 and the inner peripheral surface 4A of the frame 3 are overlapped, and the rotation guide portion 1 B of the rotating body and the inner bottom surface 4B of the frame 3 are brought into line or surface contact with each other. The rotating body 1 can stably rotate even if it is not provided with a hole and an additional bearing portion that are necessary for fitting with the convex portion in the past. -11-(9) 1227905 A plurality of movable contacts 2 A to C are arranged on the conductor 2 installed under the rotating body 1, and they can be brought into sliding contact with the corresponding fixed contacts 6a to c, respectively. On the axis of the center of the lower surface of the rotating body 1, even if the rotating position of the rotating body 1 is fixed, it is advantageous for miniaturization if movable contacts and fixed contacts are arranged on the axis line as a common terminal that is always connected. By appropriately disposing the movable contacts 2A to C and the fixed contacts 6A to C, the contacts can be connected at any rotation angle. Figure 2 shows the arrangement of the movable contact 2A and the fixed contact 6A on the axis as a common terminal. In FIG. 3A, the movable contacts 2A to C are arranged on the lower center of the rotating body, and the movable contacts 2B and 2C are arranged in the radial direction at a distance from each other. In the state shown in Fig. 2, only the movable contact 2a is connected to the fixed contact 6A. If the rotating body is rotated to the right, the position of the movable contact 2 a will not change. The movable contact 2B and the movable contact 2C move. First, the movable contact 2B is connected to the fixed contact 6B. The movable contacts 2A to c are connected by a conductor 2. Therefore, the fixed contacts 6A and 6B are in a conducting state. Furthermore, if the rotating body 1 is rotated, the movable contact 2C is also connected to the fixed contact 6c, so the fixed contacts 6A, 6B, and 6C are in a conducting state. That is to say, the rotary switch of this embodiment can switch the following three states according to the ratio of rotation: the non-conducting disconnected state of the fixed contacts 6A to 6C, and the first conducting state where the fixed contacts 6 A and 6 B are conducting. And the second on-state where the fixed contacts 6A, 6B, and 6C are conducting. In addition, the switching threshold 値 can be easily set using the arrangement of the fixed contacts 6 A to C. Furthermore, the conductor 2 is used, and the conductor 2 is formed on the flat plate portion into a shape in which the elastic arm portion is bent -12- (10) 1227905. In this case, if the conductor 2 of this shape is mounted by insert molding, On the lower surface of the rotating body 1, the flat portion of the conductor 2 can serve as a cover of the resin flowing in during the molding, and the rotating body 1 can be easily formed, and the number of parts and the number of assembling processes can be reduced. The rotary switch shown in Figures 1 to 4 can be made very small. The diameter of the frame 3 is 5.5mm, the height of the frame 3 is 2.3mm, and the height of the rotary switch itself (from the bottom of the frame 3 to the rotating body) The length of the front end of the knob part 1 of 1) is 3.6 mm. Since the rotary switch of this structure can be made very small, in a device having a structure in which two parts are connected by hinge hinges, it can be arranged on the connecting part of the two parts by rotating the hinge. It is transmitted to the knob portion of the rotating body to detect the rotational movement of the hinge hinge, so that it can be used as a switch for realizing various functions. A device with a hinged hinge to connect two components can be widely used from small electrical appliances such as mobile phones, notebook computers, video cameras, and digital cameras to large-scale electrical appliances such as refrigerators, washing machines, and photocopiers. In the case where the rotary switch shown in FIGS. 1 to 4 is suitable for a connection part of a folding mobile phone, the diameter of the frame 3 of the rotary switch is 5 · 5 mm, which is approximately the same as the diameter of the hinge leaf, and can be similar to the hinge hinge. The hinges are arranged side by side on the connecting portion. In addition, the front end of the pin of the hinge leaf is fitted to the knob part 1 A of the rotary switch, and the hinge leaf is rotated to rotate with the opening and closing of the folding mobile phone, thereby rotating the rotating body,- 13- (11) 1227905 A rotary switch for detecting the opening and closing movement of a mobile phone can be installed. When the mobile phone is made in this way, the rotary switch is in an off state when closed, and can turn off the power of the display device. When it is slightly opened, the rotary switch becomes the first on state. For example, an alarm sound is generated to inform that it has been opened. When turned on, the rotary switch is in the second ON state and can turn on the power of the display device and the like. ADVANTAGE OF THE INVENTION Since the rotary switch of this invention is provided with the rotation guide part of a rotating body at the periphery of a lower surface, a movable contact can also be arrange | positioned near the lower center of a rotating body, and the diameter of a rotating body and a frame body can be reduced. In addition, since the outer peripheral surface of the rotating body is in contact with the inner peripheral surface of the frame, the rotating body does not oscillate and can stably rotate. It is not necessary to separately provide a bearing for supporting the shaft, which can reduce the shape of the frame. size. In addition, since the rotation guide of the rotating body is in line or surface contact with the inner bottom surface of the frame body, the hole for supporting the convex portion provided on the frame body is unnecessary, and neither a cover nor a cover is required. Increasing the thickness of the frame can reduce the overall size of the frame and reduce the intrusion of dust and moisture from the outside. In addition, the 'device using the rotary switch of the present invention for the connection part of two parts' does not interfere with the design because the rotary switch capable of detecting the opening and closing state of the two parts is arranged on the connection part of the two parts. , Can design the device into an ideal shape. Furthermore, by appropriately setting the arrangement of the movable contact and the fixed contact of the rotary switch, the switch can be turned on or off at any rotary position. -14-(12) 1227905 In combination, the movable contacts are arranged in a closed space surrounded by the inner bottom surface of the frame, the lower surface of the rotating body, and the rotating guide of the rotating body. Therefore, dust and moisture can be prevented. Intrude into the space where the movable contact and the fixed contact are arranged from the outside. Furthermore, one of the movable contacts is connected to one of the fixed contacts on the axis of the rotating body, and thus the movable connected to the axis The contact point and the fixed contact point can be used as a common terminal. The movable contact point can be arranged at the lower center on the axis of the rotating body, and the diameter of the rotating body and the frame can be reduced. In addition, the conductor having the movable contact is mounted on the lower surface of the rotating body by insert molding. Therefore, the rotating body can be easily formed, and the number of parts and the number of assembling processes can be reduced.
