Description

Switch and Connector Device with Switch Function

[0001] The present invention relates to a switch and a connector device with a switch function.

[0002] In charging portable terminal devices typified by POS terminal devices, for example, a charging cradle having charging terminals arranged at the bottom on which the portable terminal device is placed is used for charging. The usage method is that the portable terminal device is simply placed on the bottom of the charging cradle for charging. In that case, for example, since the charging cradle itself is always in the power-on state, there is consumption of wasted standby power, and a live wire insertion / removal countermeasure is required on the connector side having the charging terminals by a contact sequence.

[0003] Japanese Patent Application Laid-Open No. 2013-45534

[0004] As described above, conventionally, consumption of wasted standby power and a live wire insertion / removal countermeasure have been problems.

[0005] An example of the object of the present invention is to provide a switch and a connector device with a switch function that can turn on / off power supply to various devices and is applicable to power consumption reduction and the like.

When the device is placed on the device mounting surface, the movable member moves and the movable contact short-circuits between the paired fixed contacts.

[0007] According to the above aspect of the present invention, it is possible to realize a switch and a connector device with a switch function that can turn on / off power supply to various devices and is applicable to power consumption reduction and the like.

[0009] (Embodiment 1) A switch and a connector device with a switch function according to Embodiment 1 of the present invention will be described with reference to Figures 1 to 7. As shown in these figures, the connector device with a switch function 1 comprises a housing 10, a switch 20 attached thereto, and a plurality of spring connectors 30.

[0010] As shown in Figure 1, the upper surface of the housing 10 is a device mounting surface 11 on which the portable terminal device 40 shown in Figure 3 is placed. The device mounting surface 11 has positioning protrusions 12 that fit into or engage with positioning recesses 41 of the portable terminal device 40. The positioning protrusions 12 fit into or engage with the positioning recesses 41 of the portable terminal device 40, thereby positioning the portable terminal device 40 at a predetermined position on the device mounting surface 11. A mounting flange 13 is formed on the lower part of the housing 10, extending laterally. The bottom surface of the housing 10 is a substrate mounting surface 14 on which a substrate 50 for electrical wiring is mounted. The substrate mounting surface 14 has a plurality of positioning protrusions 15 that protrude downward from the bottom surface of the housing 10. The substrate 50 has a plurality of positioning holes 51 that penetrate in the vertical direction. The substrate 50 is positioned and mounted at a predetermined position on the substrate mounting surface 14 of the housing 10 by the plurality of positioning holes 51 fitting into the corresponding positioning protrusions 15. The housing 10 has a through-hole 16 for inserting and positioning a switch 20 and a plurality of through-holes 18 for inserting and positioning a plurality of spring connectors 30. As shown in Figure 1, the through-hole 16 and the plurality of through-holes 18 are formed to extend in the vertical direction of the housing 10. The housing 10 also has a recess 19 formed in the bottom region including each of the openings of the through-hole 16 and the plurality of through-holes 18, which is recessed upward from the substrate mounting surface 14. A portion of the switch 20 placed in the through-hole 16 and a portion of the plurality of spring connectors 30 placed in each of the plurality of through-holes 18 are placed in the internal space of the recess 19. In addition, the connection pins 32 of the plurality of spring connectors 30, which will be described later, are connected to the substrate 50 through the internal space of the recess 19. Furthermore, the fixed contacts 21A and 21B, which will be described later, connected to the substrate 50 are connected to the movable member 22 through the internal space of the recess 19.

[0011] The recess 19 serves, for example, as a relief for the press-fitting jig when press-fitting the connecting pin 32 into the positioning hole 51 of the substrate 50, and also as a solder relief when soldering the connecting pin 32, which has been press-fitted into the positioning hole 51 of the substrate 50, to the substrate 50, or when soldering the ends of the fixed contacts 21A and 21B, which will be described later, to the substrate 50. By providing this recess 19, the workability of press-fitting and soldering the connecting pin 32 to the substrate 50, and soldering the fixed contacts 21A and 21B, which will be described later, can be improved.

[0012] As shown in Figures 4 and 5, the switch 20 comprises a pair of fixed contacts 21A and 21B positioned on the opposite side (bottom side) of the equipment mounting surface 11 of the housing 10, a movable member 22 positioned in a through hole 16 so as to be movable in the vertical direction, a coil spring 28 that biases the movable member 22 inside the through hole 16 in a protruding direction so as to protrude from the equipment mounting surface 11, and an X-ring 29 as a waterproof elastic body to prevent water from entering between the through hole 16 and the movable member 22.

[0013] The pair of fixed contacts 21A and 21B are formed from conductive, elastic metal leaf springs. The leading ends of the fixed contacts 21A and 21B are positioned in the fixed contact placement recess 19a, which opens to the bottom surface of the recess 19. As shown in Figure 4, the fixed contacts 21A and 21B extend upward from the end connected to the substrate 50, and further curve in an arc within the fixed contact placement recess 19a, extending toward the recess 19 so as to move toward each other. The leading ends of each fixed contact 21A and fixed contact 21B (the ends opposite to the ends connected to the substrate 50) are arc-shaped so as to face each other, as shown in Figure 4. The spacing between these leading ends is such that the movable contact 24, which will be described later, fits into it. When the movable contact 24 fits into this spacing, it contacts each leading end, enabling a short circuit between the fixed contacts 21A and 21B.

[0014] The movable member 22 is made of a conductive metal, with one end being a cylindrical head 23 that can protrude from the through hole 16, and the other end being a movable contact 24 that can short-circuit the fixed contacts 21A and 21B. In other words, the movable member 22 is formed in the following order from the head 23 toward the fixed contacts 21A and 21B: a small diameter cylindrical portion 25a, a large diameter flange portion 25b, a large diameter cylindrical portion 25c, a small diameter flange portion 25d, and a spherical movable contact 24. The through hole 16 is a stepped hole and has a large diameter portion 16a into which the head 23, the small diameter cylindrical portion 25a, and the large diameter flange portion 25b fit, a medium diameter portion 16b which is smaller in diameter than the large diameter portion 16a and into which the coil spring 28 fits, a small diameter portion 16c which is smaller in diameter than the medium diameter portion 16b and slidably supports the large diameter cylindrical portion 25c, and a bottom hole portion 16d which is slightly larger in diameter than the small diameter portion 16c. Therefore, a stepped surface 17a is formed between the large diameter portion 16a and the medium diameter portion 16b, a stepped surface 17b is formed between the medium diameter portion 16b and the small diameter portion 16c, and a stepped surface 17c is formed between the small diameter portion 16c and the bottom hole portion 16d.

[0015] The coil spring 28 is positioned around the large-diameter cylindrical portion 25c. The tip of the coil spring 28 abuts against the large-diameter flange portion 25b of the movable member 22. The base end of the coil spring 28 abuts against the stepped surface 17b. The head 23 is biased by the coil spring 28 to protrude from the equipment mounting surface 11 of the housing 10. The X-ring 29, acting as a waterproof elastic body, is positioned around the small-diameter cylindrical portion 25a so as to move integrally with the movable member 22. It makes watertight contact with the inner circumferential surface of the large-diameter portion 16a of the through hole 16 and also makes watertight contact with the outer circumferential surface of the small-diameter cylindrical portion 25a, thereby preventing water or other liquids from entering the bottom side of the housing 10. When an external force is applied downward, the head 23 of the movable member 22 moves into the through hole 16 against the biasing force of the coil spring 28 (the coil spring 28 compresses).

[0016] As shown in Figure 4, when the switch 20 is not in operation and no external force is applied, the head 23 of the movable member 22 protrudes from the equipment mounting surface 11 of the housing 10 due to the biasing force of the coil spring 28. Also, the leading ends of the pair of fixed contacts 21A and 21B and the movable contact 24 of the movable member 22 are spaced apart (not in contact). At this time, the small diameter flange portion 25d abuts against the stepped surface 17c, preventing the movable member 22 from coming out towards the tip.

[0017] As shown in Figure 5, when an external force F is applied to the switch 20 (head 23 of the movable member 22), the head 23 of the movable member 22 is pushed down against the biasing force of the coil spring 28, and the movable contact 24 of the movable member 22 enters between the pair of fixed contacts 21A and 21B, contacting the leading ends of the pair of fixed contacts 21A and 21B, short-circuiting the fixed contacts 21A and 21B and making them electrically conductive. The amount of downward pressure on the head 23 is limited by the large-diameter flange portion 25b contacting the stepped surface 17a.

[0018] As shown in Figures 1 and 2, and Figures 6 and 7, the connector device with switch function 1 has a switch 20 inserted into an insertion hole 16 of the housing 10, as well as a plurality of spring connectors 30 inserted into each of the plurality of through holes 18 of the housing 10. In Figures 1 and 2, and Figures 6 and 7, one spring connector 30 is placed on each side of the switch 20. The spring connector 30 has a spring pin 31 at its tip, which serves as a connection terminal that electrically contacts the electrode 42 of the mobile terminal device 40 shown in Figure 3, which is the mating device. The spring pin 31 is exposed on the device mounting surface 11 of the housing 10. The tip of the spring pin 31 protrudes from the device mounting surface 11. As shown in Figures 1 and 6, the tip of this protruding spring 31 is lower in the vertical direction than the tip of the head 23 of the movable member 22 of the switch 20. This is because, before the spring pin 31 of the spring connector 30 contacts the electrode 42 of the mobile terminal device 40, an external force is applied to the head 23 of the movable member 22 of the switch 20 to initiate the movement of the movable member 22. After initiating the movement of the movable member 22, the spring pin 31 is brought into contact with the electrode 42, and then the movable contact 24 of the movable member 22 is inserted between the fixed contacts 21A and 21B to short-circuit the fixed contacts 21A and 21B.

[0019] Thus, in this embodiment, the connector device 1 with a switch function is configured such that the electrode 42 of the mobile terminal device 40 and the spring connector 30 come into contact before the fixed contacts 21A and 21B are short-circuited. Various numerical values ​​are determined for this configuration, including the amount of protrusion of the spring pin 31 of the spring connector 30, the amount of protrusion of the head 23 of the movable member 22, and the amount of movement of the movable member 22, taking into account the timing of the spring pin 31 coming into contact with the electrode 42 and the timing of the movable contact 24 of the movable member 22 short-circuiting the fixed contacts 21A and 21B.

[0020] In this embodiment, the amount of protrusion of the head 23 of the movable member 22 from the equipment mounting surface 11 is greater than the amount of protrusion of the spring pin 31 from the equipment mounting surface 11. However, this is not limited to the above, as long as the spring pin 31 of the spring connector 30 is electrically connected to the electrode 42 of the mobile terminal device 40 before the fixed contacts 21A and 21B are short-circuited.

[0021] Furthermore, a circuit board 50 for electrical wiring is mounted on the circuit board mounting surface 14 of the housing 10. The housing 10 and the circuit board 50 are positioned by fitting the positioning projection 15 of the housing 10 into the positioning hole 51 of the circuit board 50. The lead-out ends of the fixed contacts 21A and 21B of the switch 20 are led out and fixed to the circuit board 50. In addition, the connection pin 32 on the base end side of the spring connector 30 is fixed to the circuit board 50 by solder or the like. The connection pin 32 is connected to the voltage output terminal of the charging power supply via the wiring of the circuit board 50, in the case of the charging cradle 60 shown in Figure 3. The switch 20 is used as a switch to turn the power supply of the charging power supply on / off, in the case of the charging cradle 60 shown in Figure 3.

[0022] Figure 3 shows a charging cradle 60 with a switch-function connector device 1 attached, and a portable terminal device 40 that can be placed on it. Figures 1, 6, and 7 show only a part of the housing 61 of the charging cradle 60. The mounting flange 13 of the housing 10 of the switch-function connector device 1 is attached to the housing 61 via a packing 65. The device mounting surface 11 of the housing 10 is exposed through the placement window 62 of the housing 61.

[0023] In the configuration of Embodiment 1 described above, the operation of the switch-function connector device 1 will be explained in the case where the switch-function connector device 1 is attached to the charging cradle 60 shown in Figure 3. When the portable terminal device 40 is not placed on the charging cradle 60, as shown in Figure 6, the switch 20 is in a non-operating state and the fixed contacts 21A and 21B are off (not short-circuited). Therefore, the charging power supply attached to the charging cradle 60 is not energized, and no unnecessary power consumption occurs.

[0024] When the portable terminal device 40 is placed on the charging cradle 60, the positioning protrusion 12 on the device mounting surface 11 enters the positioning recess 41 of the portable terminal device 40, positioning the two together. As the portable terminal device 40 is placed on the device mounting surface 11, gravity from the portable terminal device 40 is applied to the switch 20. That is, the bottom surface of the portable terminal device 40 comes into contact with the head 23 of the movable member 22, and an external force is applied to the head 23, pushing it down. The spring pin 31 of the spring connector 30 comes into contact with the electrode 42 of the portable terminal device 40, making electrical contact. Subsequently, as shown in Figure 7, when the movable member 22 has completely descended due to the gravity of the portable terminal device 40, the movable contact 24 at the end of the movable member 22 enters between the fixed contacts 21A and 21B and is held in place by the elasticity of the fixed contacts 21A and 21B. As a result, after the spring pin 31 and the electrode 42 make electrical contact, the fixed contacts 21A and 21B are short-circuited and conductive at the movable contact 24, and at this point, power is supplied to the charging power supply, and the required charging operation is performed.

[0025] When the portable terminal device 40, which was placed on the charging cradle 60, is removed from the charging cradle 60, the movable contact 24 separates from the fixed contacts 21A and 21B, and the two become non-conductive, interrupting the power supply to the charging power source and stopping the charging operation. Subsequently, the spring pin 31 and the electrode 42 of the portable terminal device 40 separate and become electrically non-contact.

[0026] According to this embodiment, the following effects can be achieved.

[0027] (1) The switch 20, which is operated by the gravity of various devices placed on the device mounting surface 11 of the housing 10, comprises a pair of fixed contacts 21A and 21B located on the opposite side of the device mounting surface 11 of the housing 10, a movable member 22 that is movable relative to the housing 10 and has a movable contact 24 at one end that can short-circuit the fixed contacts, and a coil spring 28 that biases the movable member 22 in a direction that protrudes relative to the device mounting surface 11. Therefore, it can detect whether or not various devices are placed on the device mounting surface 11 and turn the power supply to the various devices on / off, which can be applied to reduce power consumption, etc.

[0028] (2) The pair of fixed contacts 21A and 21B are elastic conductive leaf springs, and can contact and clamp the movable contact 24 at the end of the movable member 22 by elastic force, so that the on / off operation of the switch 20 is reliable and reliable repeated on / off operation is possible.

[0029] (3) The housing 10 has a through hole 16, a movable member 22 is movably positioned in the through hole 16, and an X-ring 29, which serves as a waterproof elastic body, is positioned between the outer circumference of the movable member 22 and the inner circumference of the through hole 16. This prevents water or other liquids from entering the inside (bottom side) of the housing 10 through the through hole 16.

[0030] (4) As a measure against hot-wire insertion and removal, it is possible to have a contact sequence in which, after the spring pin 31, which serves as a connection terminal, and the electrode 42 make contact, the fixed contacts 21A and 21B of the switch 20 are short-circuited by the movable contact 24. Therefore, there is no spark generation between the spring pin 31 and the electrode 42, and no contact failure resulting therefrom occurs. In addition, it becomes unnecessary to provide multiple types of contacts in consideration of the contact sequence, resulting in cost reduction effects such as standardization of parts and simplification of assembly.

[0031] (5) The connection terminal for electrically contacting the electrode 42 of the portable terminal device 40 is a spring pin 31 protruding from the housing 10. The elastic force of the spring pin 31 generates contact pressure to the electrode 42, ensuring reliable electrical connection between the electrode 42 and the spring pin 31.

[0032] (Embodiment 2) Figure 8 shows a switch 20A and a connector device 1A with a switch function according to Embodiment 2 of the present invention. In the switch 20A of Embodiment 2, instead of a movable member made entirely of conductive metal, a movable member 22A is used in which only the component part of the movable contact 24A is made of conductive metal, and the other components are made of an insulator. This makes it possible to reduce the weight and cost of the movable member 22A. Other configurations and effects are the same as in Embodiment 1.

[0033] (Embodiment 3) Figure 9 shows a switch 20B and a connector device 1B with a switch function according to Embodiment 3 of the present invention. In the switch 20B of Embodiment 3, the pair of fixed contacts 21C and 21D have a non-elastic structure (or a structure that does not require elasticity), while the movable member 22B of the switch 20B is composed of a spring pin in which the movable contact 24B protrudes downward from the large-diameter cylindrical portion 25c by the elastic force of a spring (not shown). Therefore, when the movable member 22B is pushed down, the movable contact 24B makes contact with the fixed contacts 21C and 21D, and in that contact state, the spring (not shown) compresses, causing it to move into the large-diameter cylindrical portion 25c. The movable contact 24B can then short-circuit and make the fixed contacts 21C and 21D electrically connected. The structure of the fixed contacts 21C and 21D can be simplified. Other configurations and effects are the same as in Embodiment 1.

[0034] The embodiments and modifications of the present invention have been described above with reference to the drawings, but these are merely examples of the present invention, and various other configurations can also be adopted.

[0035] In Embodiment 1 and other examples, the fixed contacts are shown as a pair, but there may be multiple pairs, and it is also possible to configure multiple pairs of fixed contacts to be turned on / off simultaneously by a movable member. Furthermore, although the fixed contacts are shown as a pair, the fixed contacts do not have to be in a paired structure; the fixed contacts can be short-circuited by the movable contacts.

[0036] In Embodiment 1 and other embodiments, multiple spring connectors 30, whose tips serve as connection terminals, are arranged on the equipment mounting surface 11 of the housing 10, and switches 20 are placed between the spring connectors 30. However, the switches 20 only need to be positioned in a location that allows them to be operated by various devices that electrically contact the spring connectors 30, and only need to be placed near the spring connectors 30. Alternatively, other connection means may be used instead of the spring connectors 30.

[0037] In Embodiment 1 and other embodiments, the operation was described in the case where it was applied to a charging cradle, but the present invention can also be applied to applications that detect when various devices other than charging devices are placed on the device mounting surface and turn the power supply to those devices on / off.
