## Background
BACKGROUND
The present invention is related to a slide switch for various kinds of electronic devices.
A slide switch used in various kinds of compact electronic devices such as a portable telephone is known as disclosed in Patent Document 1. With a recent miniaturization of the devices, such a slide switch is also requested to be miniaturized.
The slide switch disclosed in the Patent Document 1 includes, as shown in FIG. 10, a substantially box shaped case 101 opened in an upper face and made of an insulating resin, a cover 105 which covers the opening part on the upper face of the case 101, a movable contact which comes into resilient contact with a fixed contact fixed on an inner bottom face of the case 101 to form a switch contact, an operating member 103 having an operating part 103A protruding from a side face of the case 101, accommodated in the case 101 so as to be movable rightward and leftward and having the movable contact attached and terminals 112 extended from the fixed contact and protruding outward from an end part of the case 101. The operating part 103A is slid to switch the switch contact and an electric signal is outputted to an electronic circuit of a device through a wiring pattern on a wiring board from the terminals 112 to switch various kinds of functions of the device.
For instance, in the usual slide switch disclosed in the Patent Document 1, ends of the terminals 112 are formed to protrude outside the side face of the case 101, so that the wiring patterns for connecting the terminals 112 to an external part are provided in an outer area of the case 101 on the wiring board. Accordingly, since the wiring patterns are respectively provided so as to surround an outer periphery of the case 101, especially, when the number of the terminals of the slide switch is large, an area occupied by the wiring patterns is wide. Thus, it cannot be necessarily said that a wiring efficiency on the wiring board is good. Further, since the ends of the terminals 112 protrude outside the case 101, a distance between another electronic part on the wiring board and the end of the terminal part 112 of the slide switch is shortened. Accordingly, there is a fear that an electrostatic discharge may possibly arise between the end of the terminal part 112 of the slide switch and another electronic parts to break the electronic parts.

SUMMARY
In such a usual slide switch as described above, the wiring pattern is not provided immediately below. Therefore, the inventor has found that, if the wiring pattern is provided in an area located immediately below the slide switch, the wiring pattern can be made to be more highly dense and an entire part of the device including an attaching board can be more miniaturized. And if the terminal part is exposed only in a bottom face, the distance between the terminal part of the slide switch and another electronic part can be more increased to prevent another electronic part from being broken.
It is therefore one advantageous aspect of the present invention to provide a slide switch in which a wiring pattern of an attaching board is made to be highly dense and there is little fear that an electrostatic discharge may arise between another electronic parts and the slide switch.
According to one aspect of the invention, there is provided a slide switch comprising:
a housing including a first face provided with an accommodating recessed part and a second face configured to be attached to an attaching board;
a plurality of fixed electrodes, provided in the accommodating recessed part, and each of which having an external terminal exposed on the second face; and
a slider, having a movable electrode configured to be electrically conducted to the fixed electrodes, and movably provided in the accommodating recessed part so as to switch an electrical conducted state of the movable electrode and the fixed electrodes.
Each of the fixed electrodes may include a solder part inclined with respect to the second face and extending from the external terminal to the first face.
Each of the solder parts may include two portions which are provided in both sides of the external terminal in a moving direction of the slider.
A recessed part communicating one of spaces defined between the solder parts and the attaching board with an outer side of a side part of the housing may be provided in an outer peripheral end part of the second face.
A partition part may be provided between the spaces on the second face to prevent the spaces from communicating with each other.

DETAILED DESCRIPTION OF EXEMPLIFIED EMBODIMENTS
Referring to the drawings, a slide switch 1 according to a first embodiment of the present invention will be described below.
FIG. 1 is an exploded perspective view of a slide switch 1 according to the first embodiment of the present invention. FIG. 2 is a perspective view showing a bottom face of the slide switch 1. As shown in FIG. 1, the slide switch 1 includes a housing 2 having an accommodating recessed part 2a provided on an upper face, which is claimed as a first face, first to third fixed electrodes 3 to 5 fixed to the housing 2, a movable electrode 6 which can come into contact with the first to third fixed electrodes 3 to 5, a slider 7 to which the movable electrode 6 is attached to be movable in a prescribed direction (rightward and leftward in an illustrated example) in the accommodating recessed part 2a and a cover 8 made of metal which covers an opening of the accommodating recessed part 2a. The slide switch 1 of this embodiment forms a switch having one contact and two circuits by the three first to third fixed electrodes 3 to 5 and the one movable electrode 6. In such a slide switch 1, a bottom face 2d, which is claimed as a second face, of the housing 2 is attached to an attaching board 9 so as to abut thereon.
The housing 2 is formed with a thin box shaped resin member and is provided with the accommodating recessed part 2a on the upper face thereof. The accommodating recessed part 2a is formed substantially in a rectangular shape and the first to third fixed electrodes 3 to 5 are arranged therein in parallel. The length (a transverse length in FIG. 1) of the accommodating recessed part 2a determines a moving stroke of the slider 7. Further, as shown in FIG. 2, on a bottom face 2d of the housing 2, positioning protrusions 2e are provided. Thus, the slide switch 1 can be attached to the attaching board with good positioning accuracy.
In the slider 7, a handle part 7a is extended outside the slide switch 1 through an opening 2b provided in a side face of the housing 2. To a lower face of the slider 7, the movable electrode 6 is attached. The movable electrode 6 includes contact terminals so as to correspond to the first to third fixed electrodes 3 to 5, and bent parts are provided in their ends so that they may come into resilient contact with below-described contact terminals 3a to 5a of the first to third fixed electrodes 3 to 5. In order to easily resiliently deform the contact terminals of the movable electrode 6, slits may be provided in the longitudinal direction of the contact terminals of the movable electrode 6.
The cover 8 includes a top plate part 8a and one pair of leg parts 8b protruding from the top plate part 8a and extending along side walls of the housing 2. When the leg parts 8b are engaged with pawl parts 2c provided in side face of the housing 2, the cover 8 is fixed to the housing 2.
On a face of the slider 7 opposed to the cover 8, positioning recessed parts 7b are formed which have a plurality (two in the illustrated example) of recessed parts formed adjacently. Further, at a position of the cover 8 corresponding to the positioning recessed parts 7b, a resilient abutting part 8c is provided which is formed by bending a metal piece in the shape of “<”. When the slider 7 is moved, a top part of the resilient abutting part 8c of the cover 8 is located in any of the positioning recessed parts 7b to keep a position of the slider 7.
Referring to FIGS. 3 to 5E, the first to third fixed electrodes 3 to 5 will be described below in detail. FIG. 3 is a top view showing the slide switch 1 with the cover 8 and the slider 7 omitted for an explanation. Further, FIGS. 4A and 4B are respectively sectional views taken along a line IVa-IVa and a line IVb-IVb in FIG. 3. Further, in FIG. 3, areas shown by hatchings show areas of the first to third fixed electrodes 3 to 5 exposed in the accommodating recessed part 2a. Further, FIGS. 5A to 5E show diagrams illustrating the slide switch 1. FIG. 5A is a front view of the slide switch 1, FIG. 5B is a left side view (the handle part 7a side of the slider 7), FIG. 5C is a top view of the slide switch 1, FIG. 5D is a right side view of the slide switch 1 and FIG. 5E is a bottom view of the slide switch 1.
The first to third fixed electrodes 3 to 5 respectively include the contact terminals 3a to 5a which are exposed to the accommodating recessed part 2a and can come into contact with the movable electrode 6 and external terminals 3b to 5b exposed to the bottom face 2d of the housing 2 and connected to a lead-out wiring provided on the attaching board 9. The first to third fixed electrodes 3 to 5 are formed integrally with the housing 2 by an insert molding.
The first fixed electrode 3 is a metal member arranged substantially at a central part of the accommodating recessed part 2a of the housing 2 and having a substantially U shape in top view. The first fixed electrode 3 includes an elongated connecting terminal 3a exposed on the accommodating recessed part 2a, the external terminal 3b exposed on the bottom face 2d of the housing 2, an extending part 3c which goes around the connecting terminal 5a of the third fixed electrode 5 from the connecting terminal 3a and extends to the handle part 7a side of the slider 7 and a solder part 3d which passes through to the bottom face 2d side of the housing 2 from the extending part 3c to form an inclined face inclined relative e to the bottom face 2d of the housing 2. Further, in an opposite side to the extending part 3c relative to the external terminal 3b, are provided an additional solder part 3e and a support face 3f exposed on the accommodating recessed part 2a. 
Since the connecting terminal 3a of the first fixed electrode 3 is formed over an entire length of the stroke of the slider 7, the movable electrode 6 is constantly electrically conducted to the first fixed electrode 3 irrespective of the position of the slider 7.
The second fixed electrode 4 is an elongated metal member provided in a side opposite to the handle part 7a of the slider 7 with respect to the first fixed electrode 3 and extending in a moving direction of the slider 7. The second fixed electrode 4 includes the connecting terminal 4a provided in one end of the stroke of the slider 7 and exposed on the accommodating recessed part 2a, the external terminal 4b exposed on the bottom face 2d of the housing 2, a solder part 4d which connects the connecting terminal 4a to the external terminal 4b to form an inclined face inclined relative to the bottom face 2d of the housing 2, an additional solder part 4e provided in an opposite side to the contact terminal 4a with respect to the external terminal 4b and a support face 4f further exposed on the accommodating recessed part 2a from the additional solder part 4e. A section of the first fixed electrode 3 including the external terminal 3b has substantially the same form as that of a section of the fixed electrode 4 shown in FIG. 4A.
The third fixed electrode 5 is an elongated metal member provided in a side opposite to the second fixed electrode 4 with respect to the first fixed electrode 3 and extending in the moving direction of the slider 7. The third fixed electrode 5 includes the connecting terminal 5a exposed on the accommodating recessed part 2a, the external terminal 5b exposed on the bottom face 2d of the housing 2 and a solder part 5d which connects the connecting terminal 5a to the external terminal 5b to form an inclined face inclined relative to the bottom face 2d of the housing 2.
The connecting terminal 5a of the third fixed electrode 5 is provided in an area which is not overlapped on the connecting terminal 4a of the second fixed electrode 4 within the stroke of the slider 7. In the slide switch 1 of the present embodiment, when the slider 7 is moved, an electrically conducted state of the connecting terminal 3a of the first fixed electrode 3 and the connecting terminal 4a of the second fixed electrode 4 can be switch to an electrically conducted state of the connecting terminal 3a of the first fixed electrode 3 and the connecting terminal 5a of the third fixed electrode 5.
The contact terminals 3a to 5a of the first to third fixed electrodes 3 to 5 are provided to be substantially parallel to the bottom face of the accommodating recessed part 2a and can smoothly come into contact with the movable electrode 6. The external terminals 3b to 5b of the first to third fixed electrodes 3 to 5 are also provided to be substantially parallel to the bottom face 2d of the housing 2. Thus, when the slide switch 1 is attached to the attaching board 9, a contact area to a wiring pattern on the attaching board 9 is increased.
All the external terminals 3b to 5b are provided at central parts in the longitudinal direction of the first to third fixed electrodes 3 to 5 in top view and located in the central part of an entire part of the slide switch 1. When the external terminals 3b to 5b are located in the central part of the slide switch 1 in such a way, even when the slide switch 1 is heated to be bent during a soldering operation, a distance between the external terminals 3b to 5b and the attaching board 9 is hardly widened, so that there is little fear that the slide switch 1 slips out the attaching board 9.
In the slide switch 1 formed as described above, since the external terminals 3b to 5b of the first to third fixed electrodes 3 to 5 are respectively exposed on the bottom face 2d of the housing 2, a lead-out line can be wired on an area of the attaching board 9 opposed to the bottom face 2d of the housing 2, which is usually a dead space, to improve a wiring efficiency. Further, as compared with a case that a lead-out line is wired on an outer peripheral edge of a slide switch so as to avoid the slide switch as in the usual switch, the outer peripheral edge of the slide switch 1 can be used for another wiring to improve the wiring efficiency.
Further, the external terminals 3b to 5b of the first to third fixed electrodes 3 to 5 are respectively exposed on the bottom face 2d of the housing 2 and the external terminals 3b to 5b are not exposed to a side face of the housing 2. Accordingly, since entire parts of the first to third fixed electrodes 3 to 5 are not exposed to an outer part from the side face of the housing 2 and are spaced from other adjacent electronic parts, there is little fear that the electronic parts may be broken due to an electrostatic discharge. Therefore, the first to third fixed electrodes 3 to 5 are respectively set to such sizes as to accommodate their entire parts in the accommodating recessed part 2a. Namely, in the present embodiment, the entire lengths of the first to third fixed electrodes 3 to 5 are set to be shorter than the length of the slider 7 in the moving direction in the accommodating recessed part 2a. 
Further, as shown in FIG. 2, the solder parts 3d, 4d, 5d and the additional solder parts 3e and 4e are provided so as to be inclined relative to the bottom face 2d of the housing 2. Therefore, as shown in FIG. 4, between the solder parts 3d, 4d and 5d and the attaching board 9 and between the additional solder parts 3e and 4e and the attaching board 9, spaces having an acute angle are formed. When the slide switch 1 is attached to the attaching board 9, since solder fillets A can be effectively formed in gaps having the acute angle, an adhesion area of solder is increased to improve solder strength.
Further, as shown in FIG. 2, on an outer peripheral end part of the bottom face 2d of the housing 2, recessed parts 2f are provided which allow the spaces of the acute angle formed between the solder parts 3d, 4d and 5d and the attaching board 9 and between the additional solder parts 3e and 4e and the attaching board 9 to communicate with an outer side of a side part of the housing 2. The recessed parts 2f of the present embodiment are formed with inclined faces similarly to the solder parts 3d, 4d and 5d and the additional solder parts 3e and 4e and spaces similar to the spaces formed between the solder parts and the attaching board are formed between the recessed parts 2f and the attaching board 9.
Further, since the external terminals 3b to 5b of the first to third fixed electrodes 3 to 5 are not exposed to the side face of the housing 2 and arranged in the central part of the bottom face 2d of the housing 2, the solder parts 3d to 5d and the additional solder parts 3e and 4e adjacent to the external terminals 3b to 5b are also located in the central part of the bottom face 2d of the housing 2. Accordingly, even when the slide switch 1 is heated to generate a warp or deformation in the housing 2 made of the resin during the soldering operation, the distance between the solder parts 3d to 5d and the additional solder parts 3e and 4e and the face of the attaching board 9 is hardly changed. Thus, since solder can be made to easily adhere to the solder parts 3d to 5d and the additional solder parts 3e and 4e, the slide switch 1 can be assuredly attached to the attaching board 9.
As described above, since the recessed parts 2f are provided which allow the spaces formed between the above-described solder parts 3d, 4d and 5d and the attaching board 9 and between the additional solder parts 3e and 4e and the attaching board 9 to communicate with the outer side of the side part of the housing 2, whether or not the solder fillets A are preferably formed in the spaces can be observed from the side face of the housing 2 during the soldering operation. Accordingly, since whether or not the soldering operation is good can be simply recognized from the side face of the housing 2, efficiency for inspecting a good product can be improved. In the present embodiment, the recessed parts 2f are described to have the same forms as those of the solder parts 3d, 4d and 5d and the additional solder parts 3e and 4e, however, it is to be understood that any forms may be used which allow the spaces to communicated with the outer side of the side part of the housing 2 in place of the same forms as the inclined faces.
Further, on the bottom face 2d of the housing 2, a partition part 2g is provided that partitions the space formed by the solder parts 3d and 5d and the recessed part 2f provided in one side (the handle part 7a side) of the housing 2 from the space formed by the solder part 4d and the recessed part 2f provided in an opposite side of the housing 2. When the slide switch 1 is soldered to the attaching board 9, since the partition part 2g prevents the solder from extending over both the spaces, there is no fear that the external terminal 3b of the first fixed electrode 3 and the external terminal 5b of the third fixed electrode 5 provided in one side of the housing 2 is erroneously electrically conducted to the external terminal 4b of the second fixed electrode 4 provided in the other side of the housing 2.
Further, as shown in FIG. 2 and FIG. 4A, in the first fixed electrode 3 and the second fixed electrode 4, the solder parts 3d and 4d and the additional solder parts 3e and 4e are provided in both sides of the moving direction of the slider 7 with the external terminals 3b and 4b sandwiched between them. Accordingly, when the slider 7 is operated, even if a force is applied to the housing 2 in the moving direction of the slider 7, since the force is supported by the solder parts 3d and 4d and the additional solder parts 3e and 4e provided in both the sides, there is no fear that the housing 2 slips out from the attaching board 9.
A slide switch 1 according to a second embodiment will be described below by referring to FIGS. 6 to 7B. FIGS. 6, 7A and 7B are diagrams respectively showing the slide switch 11 according to the second embodiment and corresponding to FIGS. 3, 4A and 4B. Since the slide switch 11 according to the second embodiment is different from the slide switch 1 according to the above-described first embodiment only in forms of fixed electrodes 13 to 15 and a movable electrode 16, only different points will be described below.
In the slide switch 11 according to the second embodiment, the second fixed electrode 14 and the third fixed electrode 15 are arranged on one straight line. Further, the movable electrode 16 has two contact terminals including a first contact terminal 16a which constantly comes into contact with a connecting terminal 13a of the first fixed electrode 13 and a second contact terminal 16b which can selectively come into contact with one of a connecting terminal 14a of the second fixed electrode 14 or a connecting terminal 15a of the third fixed electrode 15. A slider 7 is moved to switch an electrically conducted state of the second contact terminal 16b of the movable electrode 16 and the contact terminal 14a of the second fixed electrode 14 to an electrically conducted state of the second contact terminal 16b of the movable electrode 16 and the contact terminal 15a of the third fixed electrode 15. Thus, a switch operation is realized.
Also in the second embodiment, since external terminals 13b to 15b of the first to third fixed electrodes 13 to 15 are exposed only on a bottom face 2d of a housing 2, a lead-out wiring can be provided only in an area of an attaching board 9 which comes into contact with the bottom face 2d of the housing 2, similarly to the above-described first embodiment. Since the lead-out wiring can be provided in the area which is usually a dead space, the wiring of the attaching board 9 can be formed to be more highly dense. Further, even when other electronic parts are arranged in the vicinity of a side part of the slide switch 11, since the first to third fixed electrodes 13 to 15 are separated from other electronic parts, there is no fear that the slide switch 11 or other electronic parts may be broken due to an electrostatic discharge.
Further, in the slider switch 11 according to the second embodiment, since the second fixed electrode 14 and the third fixed electrode 15 are arranged on the one straight line, the slider switch 11 can be provided in which a dimension in the direction orthogonal to the moving direction of the slider 7 is short.
Further, a space formed by a solder part 13d of the first fixed electrode 13 and a recessed part 2f, a space formed by a solder part 14d of the second fixed electrode 14 and a recessed part 2f and a space formed by a solder part 15d of the third fixed electrode 15 and a recessed part 2f are respectively partitioned by a partition part 2g, there is no fear that the external terminals 13b to 15b may be mutually electrically conducted during a soldering operation.
In the first and second embodiments, the slide switches 1 and 11 having the one contact and the two circuits are described as examples, however, a slide switch having one contact and one circuit (an ON-OFF switch) may be applied to the present invention. A slide switch 21 according to a third embodiment is shown in FIGS. 8 and 9. FIG. 8 is a perspective view of the slide switch 21 according to the third embodiment seen from a bottom face side. FIG. 9 is a diagram of the slide switch 21 similar to FIG. 3. Since the slide switch 21 according to the third embodiment is different from the slide switch 1 according to the above-described first embodiment only in forms of a fixed electrode and a movable electrode, only different points will be described below.
By referring to FIGS. 8 and 9 together, the slide switch 21 according to the third embodiment includes a first fixed electrode 23 which is constantly electrically conducted to a movable electrode 26 and is substantially U shaped in top view and a second long fixed electrode 24 which is electrically conducted to the movable electrode 26 only when the movable electrode 26 is moved to a prescribed position.
By referring FIGS. 8 and 9 together, the first fixed electrode 23 is a metal member arranged in an accommodating recessed part 2a of a housing 2 and having a substantially U shape in top view. The first fixed electrode 23 includes an elongated connecting terminal 23a exposed on the accommodating recessed part 2a, an external terminal 23b exposed on a bottom face 2d of the housing 2, an extending part 23c extending on the bottom face 2d of the housing 2 to an opposite side to a handle part 7a of a slider 7 from the connecting terminal 23a and a solder part 23d which passes through to the bottom face 2d side of the housing 2 from the extending part 23c to form an inclined face inclined relative to the bottom face 2d of the housing 2. Further, in an opposite side of the extending part 23c relative to the external terminal 23b, are provided an additional solder part 23e and a support face 23f exposed on the accommodating recessed part 2a. 
The second fixed electrode 24 is an elongated metal member extending in the moving direction of the slider 7. The second fixed electrode 24 includes a connecting terminal 24a provided in one end of the stroke of the slider 7 and exposed on the accommodating recessed part 2a, an external terminal 24b exposed on the bottom face 2d of the housing 2, a solder part 24d which connects the connecting terminal 24a to the external terminal 24b to form an inclined face inclined relative to the bottom face 2d of the housing 2, an additional solder part 24e provided in an opposite side to the contact terminal 24a with respect to the external terminal 24b and a support face 24f further exposed on the accommodating recessed part 2a from the additional solder part 24e. 
Here, the contact terminal 24a of the second fixed electrode 24 is exposed on one end on the bottom face of the accommodating recessed part 2a so that the contact terminal 24a of the second fixed electrode 24 is electrically conducted to the movable electrode 26 only when the slider 7 is moved to one end of the stroke. Namely, only when the slider 7 is moved to the one end of the stroke, the slide switch 21 electrically conducts the first fixed electrode 23, the second fixed electrode 24 and the movable electrode 26 to realize an ON-OFF operation.
Also in the slide switch 21, since the external terminals 23b and 24b of the first and second fixed electrodes 23 and 24 are exposed only on the bottom face 2d of a housing 2, a lead-out wiring can be provided only in an area of an attaching board 9 which comes into contact with the bottom face 2d of the housing 2, similarly to the above-described first embodiment and the second embodiment. Since the lead-out wiring can be provided in the area which is usually a dead space, the wiring of the attaching board 9 can be formed to be more highly dense. Further, even when other electronic parts are arranged in the vicinity of a side part of the slide switch 21, since the first and second fixed electrodes 23 and 24 are separated from other electronic parts, there is no fear that the slide switch 21 or other electronic parts may be broken due to an electrostatic discharge.
According to the slide switch of the present invention, since the external terminals of the fixed electrodes are exposed on the bottom face of the housing 2, the lead-out wiring can be provided in the area of the attaching board which comes into contact with the bottom face of the housing. Accordingly, since the lead-out wiring can be provided in the area which is usually a dead space, the wiring of the attaching board can be formed to be more highly dense.
Further, the external terminals of the fixed electrodes are exposed only on the bottom face of the housing and the fixed electrodes are not exposed on the side face of the housing. Accordingly, even when other electronic parts are arranged in the vicinity of the side part of the slide switch, since the fixed electrodes are separated from other electronic parts, there is no fear that the slide switch or other electronic parts may be broken due to an electrostatic discharge.
