Description

  The present invention relates to a housing structure of an electronic device for attaching various instrumentation electronic devices such as a signal converter and a measurement control remote input / output device to a DIN rail or the like.

  Conventionally, as a structure for locking a circuit board housed in a housing at a predetermined position, an opening is provided at a predetermined position of the circuit board, and a locking claw that fits into the opening is also provided on the housing side. The structure to provide was known (for example, refer patent document 1).

  In this structure, the circuit board is fixed at a predetermined position by the locking claws.

  The prior art will be described with reference to a cross-sectional view of a structure for locking the conventional circuit board shown in FIG. 15 at a predetermined position.

  When the end portion of the printed wiring board 120 is inserted at a predetermined position, the claw portion of the locking claw 131 fits into the square hole 122 provided in the vicinity of the end portion of the printed wiring board 120, and the elasticity of the locking claw 131. The piece is restored, the printed circuit board 120 is locked by the locking claws 131, and the printed circuit board 120 is fixed.

  Further, as another conventional example, when a board is assembled in a chassis in which a claw part bent inward corresponding to the concave part of the board is previously formed, the concave part of the board is engaged with the claw part. Thus, a structure for positioning the substrate with respect to the chassis has been known (for example, see Patent Document 2).

Japanese Patent Laid-Open No. 9-135089 (page 7, FIG. 2) JP 2001-251070 A

  However, in the structure as described above, for example, when applied to an electronic device to be attached to a rail-like structure such as a DIN rail, the stress applied to the front panel portion cannot be reliably transmitted to the back surface of the housing, There was a problem that it was difficult to cope with the lighter and thinner casing.

  For example, in such an attachment / detachment operation of an electronic device, the user first places the electronic device in an inclined state with respect to the rail-like structure in advance, and one engagement portion (for example, a fixed claw portion) on the back surface is provided in a rail shape. One overhanging piece of the rail-like structure is placed in the gap between the rear surface of the housing and the engaging portion while contacting the front end of the overhanging piece of the structure and applying a predetermined stress to the front panel. It was necessary to push in.

  At that time, while the other engaging portion (for example, the movable claw portion) is manually retracted, the electronic device is returned to the parallel state with respect to the rail-like structure and attached by the urging force of the engaging portion. It was.

  For this reason, if the housing itself is thinned and reduced in mechanical strength due to reasons such as thinning and weight reduction, stress transmission from the front panel to the back side of the housing is hindered, and the stress applied to the front panel is attenuated. However, it does not work to the back of the housing.

  In particular, when the casing on the main body side of the electronic device is divided into a plurality of layers so as to be stacked in the direction in which the rail-like structure extends, the casing is not integrally formed into a box shape. There was a unique problem that it was difficult to obtain efficient stress transmission.

  Therefore, it has been extremely difficult to cope with the lighter and thinner casing.

  When only the rear side of the casing of the electronic device is attached to the rail-like structure, the circuit board, its mounting components, and the front panel are held by the casing itself. The body itself is easily deformed and bent, and there is a problem that the electronic apparatus cannot be stably held even if the casing is thinned.

  The present invention solves the above-mentioned conventional problems, and the front panel and the housing divided into a plurality are firmly coupled via the circuit board, so that the stress applied by the operator is applied to the front panel. Because it is reliably transmitted from the part to the back of the housing on which the slider is arranged via the circuit board, the housing structure of the electronic device with a simple configuration that makes it easy to cope with the lighter and thinner housing The purpose is to provide.

  In order to solve the above-described conventional problems, an electronic device casing structure according to the present invention has an electronic structure in a rail-like structure that extends in a predetermined direction in advance and has protruding pieces on both sides. A housing structure of an electronic device for mounting a device, the housing is divided into a plurality of cases in the direction in which the rail-like structure extends, and is arranged so as to straddle the boundary between the plurality of divided housings, A slider attached so as to be able to advance and retract to sandwich the protruding piece of the rail-like structure, and a housing divided into a plurality of housings, located on the side opposite to the side where the slider is arranged with respect to the housing divided into a plurality of housings. A front panel portion fitted to the end of the body, and a circuit board that is locked to the front panel portion and that is mounted in a direction perpendicular to the rail-like structure in a housing divided into a plurality of cases. The circuit board is provided at both end portions on the front panel side. A side locking portion is formed, a rear locking portion is formed at both end portions on the leading side in the mounting direction, and the front locking portion is a locking of a pair of front pressing pieces formed on the front panel portion. The engaging part of the pair of rear side pressing pieces formed on the inner wall on the side where the slider of the housing divided into a plurality of parts is arranged is fitted into the rear engaging part. It is characterized by.

  According to this configuration, even when the casing is thinned, stress transmission from the front panel portion to the back side of the casing is not hindered.

  In other words, the front panel part and the housing divided into a plurality of parts are firmly coupled via the circuit board, so that the stress applied by the operator is arranged from the front panel part via the circuit board to the slider. Since it is reliably transmitted to the back surface of the housing, it is easy to cope with a lighter and thinner housing.

  In addition to the above-described structure, the slider structure of the electronic device according to the present invention is divided into a plurality of sections so that the interval between the plurality of casings is not separated beyond a predetermined interval in the extending direction of the rail-like structure. It is preferable to hold the case together.

    According to this configuration, in addition to ensuring sufficient slidability, the housing divided into a plurality of parts is closely coupled, the degree of sealing of the entire housing is maintained, and the quality of the internal components can be maintained well. .

  Even if the parallelism between the portion of the slider contacting the rail-like structure and the extending direction of the rail-like structure is not maintained, the interval between the divided housings is not less than a predetermined interval. Therefore, the above effect can be obtained.

  Also, when assembling a plurality of divided housings, the slider itself does not require screws, bolts, adhesives, or other dedicated coupling members to connect the divided housings. Each housing can be closely and firmly connected.

Moreover, when attaching the housing | casing divided | segmented into these into a rail-shaped structure, since the slider pinches | interposes a rail-shaped structure, it becomes easy to attach.
In other words, despite the extremely simple configuration, both a strong coupling function between the housings divided into a plurality of cases and a sandwiching function that can easily attach the divisional housings to the rail-like structure. It can have both functions.

  In the case structure of the electronic device according to the present invention, in addition to the above configuration, the circuit board is preferably provided for each case divided into a plurality of cases.

  According to this configuration, the stress applied by the operator is independent for each case from the front panel part to the back of each case through the circuit board provided for each case, and almost Since the stress is transmitted evenly, the stress is transmitted more reliably.

  In addition to the above-described structure, the electronic device casing structure according to the present invention is such that the front-side pressing piece is formed so as to protrude from the front panel in the circuit board mounting direction, and the circuit board is disposed on both sides of the front panel. It is preferable to press inward from the end side.

  According to this configuration, the circuit board is sandwiched by the front panel portion from both sides with a substantially uniform urging force.

  In the electronic device casing structure of the present invention, in addition to the above configuration, the front latching portion of the circuit board is formed in a convex shape protruding sideways, and is formed at both side ends on the front panel portion side. It is preferable that the locking portion of the front pressing piece has an opening into which the front locking portion is fitted.

  According to this configuration, the circuit board is firmly coupled to the front panel unit.

  The housing structure of the electronic device according to the present invention has a configuration in which, in addition to the above configuration, the rear side pressing piece is in a direction opposite to the mounting direction of the circuit board from the inner wall on the side where the slider of the housing divided into a plurality is arranged Preferably, the circuit board is pressed inward from both side end portions of the inner wall.

  According to this configuration, the circuit board is sandwiched by the housing from both sides with a substantially uniform urging force.

  In addition to the above configuration, the housing structure of the electronic device according to the present invention includes a rear locking portion of the circuit board that is formed in a cutout shape at both ends on the leading side in the mounting direction, and is divided into a plurality of housings. It is preferable that the rear-side pressing piece portion of the body has a locking portion formed in a cylindrical shape at the tip portion, and the locking portion fits into the rear locking portion.

  According to this configuration, the circuit board is firmly coupled to the housing.

  Next, as shown in FIG. 1, an electronic device 10 according to an embodiment of the present invention is a device used in the field of so-called industrial measurement, and for example, voltage, current, active power, reactive power, apparent Power multimeters and power transducers that enable measurement of power and power factor and display of measurement values, signal converters that convert measurement signals of various sensors, display them, output alarms, etc. Data communication between the detection end (resistance temperature detector, differential pressure transmitter, etc.) and the transmitter / receiver (indicator, recorder, controller, PLC, DCS, computer, etc.) installed in the central control room It can be applied to various types of devices such as a remote control input / output device for measurement control performed by a network.

  In order to facilitate the following description, the width direction of the electronic device 10 is the X direction, the depth direction is the Y direction, the extending direction of the rail-like structure L that is also the height direction is the Z direction, and the X direction, the Y direction, and The Z direction is defined as directions orthogonal to each other.

  In this figure, for example, in the control box, the electronic device 10 extends in a predetermined direction such as a DIN rail in the predetermined direction (the Z direction which is the vertical direction indicated by the arrow in the present embodiment) and projects outward. The state attached to the rail-like structure L which has the overhang | projection piece part L1 at both ends is shown.

  Usually, in such a rail-like structure L, there are many measurement objects, and several tens or more of the same or similar electronic devices are adjacent to each other, and they are generally attached closely. is there.

  Here, the housing on the main body side of the electronic device 10 is equally divided into two so as to be stacked in the Z direction in which the rail-like structure L extends, and the upper housing 11 and the lower It is comprised from the side housing | casing 12. FIG.

  This eliminates the need to separately prepare dies for molding each housing in the manufacturing scene, and simplifies the manufacturing process.

  Further, a boundary K between the upper housing 11 and the lower housing 12 is formed at the contact portion.

  And in each front side of the upper side housing | casing 11 and the lower side housing | casing 12, with respect to the edge part 11a (refer FIG. 2) and the edge part 12a (refer FIG. 2) which have the level | step difference surface which made thickness thin. A front panel portion 13 is fitted.

  Furthermore, on the back side of the upper casing 11 and the lower casing 12, the rail-like structure L is opposed to each other and the boundary K between the upper casing 11 and the lower casing 12 is straddled. A first slider 14 and a second slider 15 are arranged to constitute a pair of sliders.

  In addition, although mentioned later in detail, the upper side housing | casing 11 and the lower side housing | casing 12 are the 1st circuit board 16 (refer FIG. 2) with which the front panel part 13 was mounted | worn in the housing | casing, and a 2nd circuit. The upper housing 11 and the lower housing 12 are coupled to each other by a pair of sliders composed of the first slider 14 and the second slider 15 on the back side, which are firmly coupled by the substrate 17 (see FIG. 2). Since the interval is not more than the predetermined interval, the casings (the upper casing 11 and the lower casing 12, the same applies hereinafter) are closely coupled as a whole.

  The connector insertion portion 13f (see FIG. 2) of the front panel portion 13 includes a connector portion 16a of the first circuit board 16 mounted inside and a connector portion 17a of the second circuit board 17 mounted inside. It is inserted through and engaged.

  Next, the overall internal configuration will be described in detail with reference to FIG.

  Here, the first circuit board 16 constitutes, for example, a power supply module, a plurality of signal conversion modules, or a control module that performs signal transmission control to the network, and the front side thereof is connected to an external device or an electrical network. A connector portion 16a that enables a general connection is connected.

  Similarly, the second circuit board 17 constitutes, for example, a power supply module, a plurality of signal conversion modules, or a control module that performs signal transmission control to the network. The connector part 17a which enables a general connection is connected.

  In addition, in this figure, although the connector insertion part 13f of the front panel part 13 mentioned above is shown in figure, it is electrically connected to the connector part 16a along the insertion direction to the connector insertion part 13f of the front panel part 13. The formed first circuit board 16 and the second circuit board 17 electrically connected to the connector portion 17a are arranged substantially in parallel.

  Then, a pair of front side pressing pieces 13a are integrally formed with the front panel portion 13 in the width direction so as to protrude from the upper portion of the front panel portion 13 in the mounting direction of the first circuit board 16, and the front panel portion 13 is similarly formed. A pair of front side pressing pieces 13b are integrally formed with the front panel portion 13 in the width direction so as to protrude in the mounting direction of the second circuit board 17 from the lower part of the front panel portion.

  And after the predetermined | prescribed coupling | bonding mentioned later was made | formed, a pair of front side press piece part 13a hold | maintains pressing the 1st circuit board 16 from the edge part side of the both sides, and a pair of front side press piece similarly The portion 13b holds the second circuit board 17 while pressing it from both end portions.

  Further, convex front locking portions 16b projecting sideways are formed at both side ends of the first circuit board 16 on the front panel portion 13 side, and the front panel portion of the second circuit board 17 is similarly formed. At both side end portions on the 13th side, convex forward locking portions 17b protruding sideways are formed.

  Furthermore, a notch-like rear locking portion 16c is formed at both side ends that are the leading side in the mounting direction of the first circuit board 16, and both sides that are also the leading side in the mounting direction of the second circuit board 17 are formed. A notch-shaped rear locking portion 17c is formed at the end.

  On the other hand, the upper housing 11 and the lower housing 12 are superposed in the vertical direction (Z direction), and then arranged on the back side so as to straddle the boundary K (see FIG. 6B). 14 and the second slider 15 are firmly coupled by a pair of sliders and assembled into an integral box shape with the front side opened.

  As will be described in detail later, a plurality of mounting guides (not shown) formed in the upper housing 11 in a state where the first circuit board 16 and the second circuit board 17 are coupled to the front panel unit 13 in advance. And a plurality of mounting guides 12 c formed in the lower housing 12.

  Next, a method of combining the upper housing 11 and the lower housing 12 will be described with reference to FIGS. 3 (a) and 3 (b).

  First, as shown in FIG. 3A, after the upper casing 11 and the lower casing 12 are overlapped, the first slider 14 and the second slider 15 are moved in the width direction (X direction). As shown by arrows from both sides, the rail-like structure L (not shown) is fitted in a direction to be sandwiched.

  Then, by advancing the first slider 14 and the second slider 15 respectively in the forward direction, the boundary K located on the back side of the upper housing 11 and the lower housing 12 is set as shown in FIG. It is fitted so as to straddle and is arranged at a predetermined mounting position.

  As is clear from this figure, the first slider 14 and the second slider 15 are fitted along the extending direction of the boundary K on the rear side of the casing, and are divided into two upper casings 11 and lower casings. Since the housings are held together so that the distance between them is not more than a predetermined distance in the extending direction (Z direction) of the rail-like structure L (not shown), the housings are closely and firmly Combined.

  Next, the configuration of the first slider 14 will be described in detail with reference to FIGS. 4 (a) and 4 (b).

  Here, the first slider 14 is connected to the first slider base 14a, and a first elastic piece 14b that applies an elastic force in the forward direction to the first slider base 14a according to the retraction distance of the first claw 14c. And a locking recess formed on the front surface (back surface) of the rail-like structure L in each of the upper housing 11 and the lower housing 12. 11c (see FIG. 6 (a)) and the locking concave portion 12g (see FIG. 6 (a)) have two columnar locking convex portions 14d to be fitted.

  Further, the first elastic piece portion 14b of the first slider 14 is formed of a pair of columnar bodies so as to extend in a direction across the boundary K located inside from both sides of the first slider base portion 14a. Thus, a restoring stress can be applied in a direction orthogonal to the extending direction, and therefore a predetermined urging force can be easily applied to the first slider 14.

  In other words, the two locking projections 14d are formed in the locking recess 11g formed on the surface (rear surface) where the rail-like structure L is located in each of the upper housing 11 and the lower housing 12. When the first slider base portion 14a is retracted from the initial position (the stop position before the rail-like structure L is attached) by fitting in accordance with each of the locking concave portions 12g, the first slider base portion 14a corresponds to the retreat distance. Since the elastic force in the forward direction is applied by the first elastic piece portion 14b, it acts as an urging force that sandwiches the rail-like structure L.

  Further, since the first claw portion 14c formed at the front end portion of the first slider 14 in the forward direction is formed so as to generate a gap of a predetermined height with the back surface of the upper housing 11, The protruding piece L1 (see FIG. 1) of the rail-like structure L is fitted into the gap.

  Furthermore, although the back surface of the first slider 14 is also a surface across the boundary K, on the surface, an orthogonal cross-sectional shape in the sliding direction (advancing / retreating direction) is formed by the first slider base portion 14a and the side end portions 14e. Are formed in a U-shape so that the slide concave portions 14f extending in the direction parallel to the extending direction of the boundary K are provided on both sides.

  As a result, the slide convex portion 11d (see FIGS. 6A and 7A) formed on the back surface of the upper housing 11 to be described later and the lower side are formed by two slide concave portions 14f provided on both sides. The sliding projection 12d formed on the back surface of the housing 12 can be fitted together.

  Each of the fitting portions of the sliding convex portion 11d and the sliding convex portion 12d has an L-shaped cross section in the sliding direction (advancing / retreating direction) so as to fit into the sliding concave portion 14f.

  Next, the configuration of the second slider 15 will be described in detail with reference to FIGS. 5 (a) and 5 (b).

  The second slider 15 has a second slider base portion 15a having a second claw portion 15c at the front end portion in the forward direction, and an elastic force in the forward direction according to the retraction distance of the second claw portion 15c connected to the second slider base portion 15a. Are formed at the tip of the second elastic piece 15b and the rail-like structure L of the upper housing 11 (rear surface). ) Formed in the guide recess 11e (see FIG. 6A) and the guide recess 12e formed in the surface (rear surface) of the lower housing 12 where the rail-like structure L is located (see FIG. There are two cylindrical guide protrusions 15d that are fitted in corresponding to each of (a).

  Further, the second elastic piece 15b of the second slider 15 is constituted by a columnar body (see FIG. 6A) extending from the second slider base 15a along the extending direction of the boundary K.

  As will be described in detail later, the second slider is formed by fitting a pair of guide convex portions 15d into a guide concave portion 11e formed in the upper housing 11 and a guide concave portion 12e formed in the lower housing 12. Reference numeral 15 denotes a stop position P of the guide concave portion 11e and the guide concave portion 12e (a position where the guide convex portion 15d is most advanced and stopped when pushed by hand, see FIG. 6A). Then, since the elastic force in the forward direction according to the retreat distance is given by the restoring stress of the second elastic piece portion 15b, it acts as an urging force for sandwiching the rail-like structure L.

  In addition, the second claw portion 15c formed at the front end portion of the second slider 15 in the forward direction has a predetermined height gap between the back surface of the upper housing 11 and the back surface of the lower housing 12. Since it forms so that it may arise, it has the structure where the overhang | projection piece part L1 (refer FIG. 1) of the rail-shaped structure L which is not illustrated fits in the clearance gap.

  Furthermore, the surface on the back side of the second slider 15 is also a surface across the boundary K of the housing, but on the surface, the second slider base portion 15a and both side end portions 15e slide in the sliding direction (advance / retreat direction). By forming the orthogonal cross-sectional shape into a U-shape, slide concave portions 15f extending in a direction parallel to the extending direction of the boundary K are provided on both sides.

  As a result, the slide convex portion 11d formed on the back surface of the upper housing 11 described later and the slide convex portion 12d formed on the back surface of the lower housing 12 are provided by two slide concave portions 15f provided on both sides. Can be fitted together.

  An operation portion 15g for facilitating the work of releasing the biasing stress of the second slider 15 is formed at the end of the second slider base portion 15a on the backward direction side.

  Furthermore, in the second slider 15, an opening 15h is formed so as to surround the second elastic piece 15b and the guide convex portion 15d formed at the tip thereof.

  Thus, for example, if a flat tip of a flat-blade screwdriver is inserted into the opening 15h and a stress that is displaced inwardly with respect to the guide convex portion 15d of the second elastic piece portion 15b is applied, the guide concave portion 11e and the guide concave portion 11e Since it becomes easy to remove the second slider 15 by releasing the state fitted in the recess 12e, it is necessary for adjustment and replacement of internal electronic components even after the operation as an electronic device is enabled. The housing can be disassembled accordingly.

  Next, FIG. 6A shows that the first slider 14 and the second slider 15 are fitted in the direction of the arrow along the extending direction (X direction) of the boundary K between the upper housing 11 and the lower housing 12 combined. FIG. 6B shows a state in which each slider is fitted and is in an initial position (stop position before being attached to the rail-like structure L).

  As shown in FIG. 6A, a pair of locking projections 14 d (see FIG. 4B) formed on the back side of the first slider 14 is straight with the semicircular portion of the upper housing 11. A notch-like locking recess 11g made of a portion and a notch-like locking recess 12g made of a semicircular portion and a straight portion of the lower housing 12 communicate with each other to form a racetrack shape as a whole. By being fitted into the opening, it is arranged at the initial position of the first slider 14 (stop position before being attached to the rail-like structure L) shown in FIG.

  On the other hand, a pair of guide convex portions 15d (see FIG. 5B) are fitted into the guide concave portion 11e formed in the upper housing 11 and the guide concave portion 12e formed in the lower housing 12, respectively. The second slider 15 is disposed at a position where the leading end side of the guide convex portion 15d reaches the stop position P of the guide concave portion 11e and the guide concave portion 12e shown in FIG. 6A. Stop in the state indicated.

  In the state where the housing of the electronic device 10 is attached to the rail-like structure L, the first slider 14 is in the initial position shown in FIG. 6B (before the rail-like structure L is attached). The second slider 15 moves backward from the stop position P of the guide recess 11e and the guide recess 12e shown in FIG. 6B, and the second slider 15 moves backward from the stop position P of the guide recess 15e. A restoring stress in the forward direction according to the retreat distance is applied.

  As a result, the electronic device 10 is stably held in a state in which the electronic device 10 is clamped with a substantially uniform urging force from the projecting piece L1 extending on both sides of the rail-like structure L.

  Here, as shown in FIG. 6A, the guide recess 11e and the guide recess 12e formed on the surface of the divided housing on the side where the rail-like structure L is located are arranged on both sides in the width direction. The inner wall 11f and the inner wall 12f are formed by continuous peaks and valleys along the advancing / retreating direction of the second slider 15, respectively.

  The intermediate lines in the width direction of the peaks and valleys are shown as wavy straight lines. The distance w between the two intermediate lines is a pair of guide protrusions of the second slider 15 when no restoring stress is applied. It almost coincides with the interval of 15d.

  Accordingly, the pair of guide protrusions 15d of the second slider 15 are formed on the inner side wall 11f and the inner side wall 11f, which are narrower than the interval w between the two intermediate lines, in the inner side wall 11f and the inner side wall 12f formed by continuous peaks and valleys. When located in the valley region of each wall 12f, an urging force in the forward or backward direction is applied by the restoring stress of the second elastic piece portion 15b according to the inclination direction of the contact portion.

  More specifically, in the valley region between the inner wall 11f and the inner wall 12f, the interval between the two guide protrusions 15d is smaller than the predetermined interval w between the two guide protrusions 15d. The second elastic piece 15b is elastically deformed, and an elastic force as a reaction thereof, that is, an elastic stress (restoring stress) to be elastically restored is applied.

  As a result, the restoring stress acts in a direction in which the interval between the two guide convex portions 15d approaches the predetermined interval w between the two guide convex portions 15d, and thus the interval between the inner side wall 11f and the inner side wall 12f. It acts on the second slider 15 as an urging force in the forward or backward direction along the inclination in the direction in which the angle spreads.

  Thereby, when attaching the housing | casing of the electronic device 10 to the rail-shaped structure L, if an operator pushes the 2nd slider 15 by hand and advances it little by little, according to the advance distance, a pair of inner wall 11f and inner wall 12f and the inclination direction of the contact portion change, and the urging force due to the restoring stress of the second elastic piece portion 15b acts alternately in the forward direction and the backward direction. It can be recognized tactilely, and depending on the setting of the shape of the peaks and valleys, it can be clearly and audibly recognized by clicking, clicking and impact sound, so there is no need to visually check the advanced state of the second slider 15 for installation work. Makes it easy and simple.

  Next, referring to FIG. 7A and FIG. 7B, the second slider 15 is formed on the back surface of the lower housing 12 and the slide convex portion 11 d formed on the back surface of the upper housing 11. A state in which the sliding projection 12d is held together will be described.

  FIG. 7A shows a state in which the distal end side of the guide convex portion 15d of the second slider 15 is slightly retracted from the stop position P of the guide concave portion 11e and the guide concave portion 12e and has not yet reached the stop position P. In the figure, the projecting projection 11d and the projecting projection 12d are not covered with the second slider 15 and are exposed.

  Further, as shown in FIG. 7 (b), the second claw portion 15c formed at the front end portion of the second slider 15 in the forward direction is further in the second slider 15 than in the state of FIG. 7 (a). In the advanced state, a gap having a predetermined height h is formed between the back surface of the upper housing 11 and the back surface of the lower housing 12.

  Thereby, it has the structure where the overhang | projection piece part L1 (refer FIG. 1) of the rail-shaped structure L which is not illustrated fits in the clearance gap.

  Furthermore, the surface on the back side of the second slider 15 is also a surface across the boundary K of the housing, but on the surface, the second slider base portion 15a and both side end portions 15e slide in the sliding direction (advance / retreat direction). By forming the orthogonal cross-sectional shape into a U-shape, slide concave portions 15f extending in a direction parallel to the extending direction of the boundary K are provided on both sides.

  As a result, the slide convex portion 11d formed on the back surface of the upper housing 11 and the slide convex portion 12d formed on the back surface of the lower housing 12 are combined by the two slide concave portions 15f provided on both sides. Can be fitted.

  Then, each of the fitting portions of the sliding convex portion 11d and the sliding convex portion 12d has an L-shaped cross section in the sliding direction (advancing / retreating direction) so as to fit into the sliding concave portion 15f. .

  Although not described, the first slider 14 also includes a slide convex portion 11d formed on the back surface of the upper housing 11 and a slide convex portion 12d formed on the back surface of the lower housing 12. Can be fitted.

  That is, the first slider 14 and the second slider 15 are arranged so that the distance between the upper casing 11 and the lower casing 12 does not exceed a predetermined distance in the extending direction (Z direction) of the rail-like structure L. The case is held together.

  Thereby, in addition to sufficiently ensuring the slidability, the housings divided into a plurality of parts are closely coupled, the sealing degree of the whole housing is maintained, and the quality of the internal components can be maintained well.

  Even if the parallelism between the portion of the first slider 14 or the second slider 15 that contacts the rail-like structure L and the extending direction (Z direction) of the rail-like structure L is not maintained, the upper side Since the space | interval of the housing | casing 11 and the lower housing | casing 12 is not spaced apart more than predetermined | prescribed space | interval, said effect is acquired.

  In addition, when assembling the divided housings, each slider itself does not require screws, bolts, adhesives, or other dedicated connecting members to connect the divided housings. Each housing can be closely and firmly connected.

  Moreover, when attaching the divided | segmented housing | casing to the rail-shaped structure L, since the 1st slider 14 and the 2nd slider 15 pinch | interpose the rail-shaped structure L, it becomes possible to attach easily.

  That is, in spite of an extremely simple configuration, both a strong coupling function between the divided casings and a clamping function that can easily attach the divided casings to the rail-like structure L. It can have both functions.

  The first slider 14 has slide concave portions 14f extending in a direction parallel to the extending direction of the boundary K on both sides of the surface across the boundary K of the divided housing. The sliding recesses 15f extending in the direction parallel to the extending direction of the boundary K are provided on both sides of the surface across the boundary K of the divided housing, and the sliding recesses 14f and the sliding recesses 15f are The sliding convex portion 11d and the sliding convex portion 12d formed on the divided casings can be fitted together.

  Thus, the slide convex portion 11d and the slide convex portion 12d formed in the divided housing are fitted together in the slide concave portion 14f of the first slider 14, and the slide concave portion 15f of the second slider 15 is fitted. In addition, since the sliding convex portion 11d and the sliding convex portion 12d formed on the divided casing can be fitted together, the area for applying the pressure stress for firmly attaching the divided casing is small. Thus, an efficient coupling function can be realized.

  Further, the first slider 14 and the second slider 15 are arranged so as to face each other with the rail-like structure L interposed therebetween in a state where the divided housing is attached to the rail-like structure L.

  The first slider 14 has a first slider base portion 14a having a first claw portion 14c at the front end portion in the forward direction, and is connected to the first slider base portion 14a in accordance with the retreat distance of the first claw portion 14c. The first elastic piece portion 14b for applying the elastic force to the first slider base portion 14a, and the position of the divided rail-like structure L of the housing formed at the distal end portion of the first elastic piece portion 14b. It has a locking recess 11g formed on the side surface and a pair of locking projections 14d fitted into the locking recess 12g.

  The second slider 15 includes a second slider base portion 15a having a second claw portion 15c at a front end portion in the forward direction, and is connected to the second slider base portion 15a in the forward direction according to the retraction distance of the second claw portion 15c. A second elastic piece portion 15b that applies elastic force to the second slider base portion 15a, and a tip portion of the second elastic piece portion 15b, on the side where the rail-like structure L of the divided housing is located. A guide recess 11e formed on the surface and a pair of guide protrusions 15d fitted into the guide recess 12e are provided.

  As a result, in a state where the electronic device 10 is attached to the rail-like structure L, the first slider 14 moves backward from the initial position (stop position before being attached to the rail-like structure L), and the second slider. 15, since the leading end side of the guide convex portion 15d is retracted from the stop position P of the guide concave portion 11e and the guide concave portion 12e, the first elastic piece portion 14b and the second elastic piece portion 15b according to the retreat distance. Are elastically deformed and given a restoring stress, the electronic device 10 can be stably held in a state where it is sandwiched from both sides of the rail-like structure L with a substantially uniform urging force.

  Next, referring to FIG. 8A and FIG. 8B, the first circuit board 16 electrically connected to the connector part 16a and the second circuit board electrically connected to the connector part 17a. A state before and after being inserted through the connector insertion portion 13f of the front panel portion 13 so as to be substantially parallel to each other along the insertion direction indicated by an arrow will be described.

  Here, at both side ends of the first circuit board 16 on the front panel portion 13 side, convex forward locking portions 16b protruding sideways are formed, and the front panel portion 13 of the second circuit board 17 is formed. At both side end portions on the side, convex forward locking portions 17b projecting sideways are formed.

  In the state where the first circuit board 16 and the second circuit board 17 are respectively attached to the predetermined positions of the front panel portion 13, the front locking portion 17 b is a front side pressing piece portion formed on the front panel portion 13. 13b (see FIG. 9A), and the front locking portion 16b is fitted into the opening 13c of the front pressing piece 13a formed on the front panel portion 13, respectively. .

  Next, as shown in FIG. 9A, the front pressing pieces 13 b formed at both side ends in the width direction of the front panel portion 13 are mounted in the mounting direction of the second circuit board 17 from the front panel portion 13. It is formed in a plate shape so as to protrude in the direction of the arrow shown in FIG.

  And the rectangular-shaped opening part 13c which has a long side along the protrusion direction is formed in the approximate center part.

  On the other hand, convex front locking portions 17b projecting sideways are formed at both end portions of the second circuit board 17 on the front panel portion 13 side.

  And when the 2nd circuit board 17 is penetrated to the predetermined position with respect to the front panel part 13, as shown in FIG.9 (b), the front latching | locking part 17b will be the front formed in the front panel part 13. FIG. It is fitted in the opening 13c of the side pressing piece 13b.

  Thereby, each front side pressing piece portion 13b is elastically deformed laterally and a restoring stress is applied. Therefore, the second circuit board 17 is applied with a substantially uniform urging force from both sides in the width direction orthogonal to the insertion direction. It will be pinched.

  Accordingly, the second circuit board 17 is held stably and firmly with respect to the front panel unit 13.

  Similarly, the first circuit board 16 is also held stably and firmly with respect to the front panel unit 13.

  Next, referring to FIG. 10, the first circuit board 16 and the second circuit board 17 engaged with the front panel unit 13 are connected to the upper housing 11 and the lower housing 12 combined in a box shape. The state before mounting in the direction of the arrow will be described.

  Here, in the first circuit board 16, notched rear locking portions 16 c are formed at both end portions on the leading side in the mounting direction indicated by the arrow, and similarly, the second circuit board 17 is also mounted in the mounting direction. A notch-like rear locking portion 17c is formed at both end portions on the leading side of the.

  In addition, since the width of the board gradually decreases as it approaches the head on the head side in the mounting direction further than the rear locking portion 16c of the first circuit board 16, the rear side pressing piece at the time of mounting. A cylindrical locking portion (not shown) of the portion 11b is smoothly displaced outward, and the locking portion of the rear pressing piece 11b is inserted into the rear locking portion 16c at a predetermined position. ing.

  Similarly, the columnar locking portion 12h of the rear-side pressing piece 12b is fitted and inserted into the rear locking portion 17c of the second circuit board 17, details of which will be described later.

  Further, the first circuit board 16 is attached to the upper casing 11, and the second circuit board 17 is attached to the lower casing 12 at the same time.

  At that time, the respective mounting surfaces of the first circuit board 16 and the second circuit board 17 are parallel to a plane (XY plane) orthogonal to the extending direction (Z direction) of the rail-like structure L to be attached. It is in.

  After the mounting, the rear side pressing piece 11b formed on the inner wall of the upper housing 11 on the side where the first slider 14 and the second slider 15 are arranged is arranged in the mounting direction of the first circuit board 16. It fits in each of the back latching | locking part 16c formed in the both-sides edge part used as the front side.

  Similarly, the rear side pressing piece 12b (see FIGS. 1 and 11A) formed on the inner wall of the lower housing 12 on the side where the first slider 14 and the second slider 15 are disposed is the second side. The circuit board 17 is fitted into each of the rear locking portions 17c formed at both end portions on the leading side in the mounting direction.

  Next, the manner in which the second circuit board 17 is mounted on the lower housing 12 will be described with reference to FIGS. 11 (a) and 11 (b).

  For ease of explanation, FIGS. 11 (a) and 11 (b) omit the upper half of the front panel portion 13, the first circuit board 16, and the upper housing 11, and lower the front panel portion 13. Only the side half, the second circuit board 17 and the lower housing 12 are shown.

  As shown in FIG. 11A, the first circuit board 16 (not shown) and the second circuit board 17 are both connected to the upper casing 11 (not shown) at the same timing and the same timing. It is attached to the lower housing 12 in the direction indicated by the arrow.

  Here, the second circuit board 17 sandwiched from both sides by the front panel unit 13 is formed inside the side wall of the lower housing 12 assembled in a box shape when entering the mounting direction indicated by the arrow. It can be mounted along the plurality of mounting guides 12c.

  Further, since the width of the board gradually decreases as the head side in the mounting direction further approaches the head from the rear locking portion 17c, when the second circuit board 17 is pushed, The cylindrical locking portion 12h formed at the tip of the side pressing piece 12b is smoothly displaced outward.

  Then, at the predetermined position shown in FIG. 11B, the front end of the rear side pressing piece 12b formed on the inner wall of the lower housing 12 on the side where the first slider 14 and the second slider 15 are arranged. A cylindrical locking portion 12 h (see FIG. 12A) formed in the portion is in a state of being fitted into each of the rear locking portions 17 c of the second circuit board 17.

  As a result, the rear side pressing piece 12b is elastically deformed laterally, and the restoring stress is applied to the second circuit board 17, and the two rear side pressing pieces 12b are sandwiched by the two rear side pressing pieces 12b from both sides with a substantially uniform urging force. Will be.

  In other words, the second circuit board 17 is stable with respect to the lower housing 12 while being sandwiched between the two rear pressing pieces 12b located on both sides in the width direction (X direction) with a substantially uniform urging force. Firmly held.

  As is clear from FIGS. 11A and 11B, the second circuit board 17 is pre-engaged with the front panel portion 13 and the mounting surface thereof is a rail-like structure L (see FIG. 11). 1), and mounted in a positional relationship parallel to a plane (XY plane) orthogonal to the extending direction (Z direction).

  Furthermore, with reference to FIG. 12A and FIG. 12B, the state before and after the second circuit board 17 is mounted on the lower housing 12 will be described in detail.

  In FIG. 12A, the second circuit board 17 advances in the mounting direction indicated by the arrow, and the front corner portion 17d is a cylindrical locking portion 12h formed at the tip of the rear pressing piece 12b. The state just before contacting is shown.

  Here, the rear side pressing piece 12b protrudes from the inner wall of the lower housing 12 on the side where the second slider 15 is disposed in a direction opposite to the mounting direction (arrow direction) of the second circuit board 17. Is formed.

  On the other hand, the second circuit board 17 is set so that the width length gradually decreases as the side surface on the top side goes to the top, and has an arcuate top side corner portion 17d.

  The arc-shaped leading corner portion 17d and the columnar locking portion 12h are previously installed at substantially the same position in the width direction.

  For this reason, when the second circuit board 17 is further pushed from this state, the arc-shaped leading corner portion 17d comes into contact with the locking portion 12h.

  And since the latching | locking part 12h is displaced to the side along the shape of the side surface of the 2nd circuit board 17, the back side press piece part 12b is elastically deformed to a bow shape.

  Finally, the locking portion 12h is inserted into the notch-shaped rear locking portion 17c, resulting in the state shown in FIG.

  Further, the columnar locking portion 12h formed at the tip of the rear side pressing piece 12b in this state is notched so as to be displaced laterally from the position shown in FIG. The position of the rear locking portion 17c is set in advance.

  Thereby, the rear side pressing piece 12 b is elastically deformed laterally, and the restoring stress acts on the second circuit board 17.

  Therefore, the second circuit board 17 is sandwiched with a substantially uniform biasing force from both sides.

  In other words, the second circuit board 17 is stable with respect to the lower housing 12 while being sandwiched between the two rear pressing pieces 12b located on both sides in the width direction (X direction) with a substantially uniform urging force. Firmly held.

  Although explanation is omitted, the first circuit board 16 is similarly held in a state where it is sandwiched by two substantially uniform urging forces from the two rear pressing pieces 11b located on both sides in the width direction (X direction). It is held stably and firmly with respect to the side housing 12.

  Moreover, the opening part 12k is formed so that the back side press piece part 12 and the column-shaped latching | locking part 12h formed in the front-end | tip part may be surrounded.

  Thus, for example, when a flat tip of a flathead screwdriver is inserted into the opening 12k and a stress that is displaced laterally is applied to the locking portion 12h of the rear side pressing piece 12b, the inserted state is released. It becomes easy.

  Therefore, even after the electronic device 10 is completed and operable, the housing can be disassembled as necessary for adjustment, replacement of internal components, and the like.

  Next, with reference to FIG. 13A and FIG. 13B, a state before and after the front panel unit 13 is fitted to the lower housing 12 will be described.

  For ease of explanation, the upper part of the front panel unit 13 and the upper part of the upper housing 11 are omitted.

  Here, the outermost peripheral portion of the front panel portion 13 is formed with an end portion 13d having a stepped surface due to thinning inside and a plurality of guide plates 13e.

  Then, the front panel portion 13 is advanced in the direction of the arrow so that the gap between the end portion 13d and the plurality of guide plates 13e and the end portion 11a having a stepped surface due to thinning outside the upper housing 11 and the lower housing. End portions 12 a having stepped surfaces due to thinning are fitted on the outside of the body 12.

  As described above, the front panel unit 13 is firmly coupled to the divided upper casing 11 and lower casing 12 through the first circuit board 16 and the second circuit board 17.

  Further, since the mounting surfaces of the first circuit board 16 and the second circuit board 17 are arranged on a plane (XY plane) orthogonal to the extending direction (Z direction) of the rail-like structure L, the width direction (XY plane) Even if a dimensional variation (particularly, a variation in a direction larger than a desired size) occurs in the X direction) or the depth direction (Y direction), the distance between the divided upper housing 11 and lower housing 12 Therefore, it is possible to prevent the rail-like structure L from being separated beyond a predetermined interval in the extending direction.

  As a result, the upper casing 11 and the lower casing 12 are closely coupled, the sealing degree of the entire casing is maintained, and the quality of the internal components can be maintained well.

  In addition, for example, in the attaching / detaching operation of the electronic device 10, the user first arranges the electronic device 10 in an inclined state with respect to the rail-like structure L in advance, and the first slider 14 is placed at the tip of one overhanging piece L 1. It is necessary to push one protruding piece L1 of the rail-like structure L into the gap between the rear surface of each housing and the first slider 14 while applying a predetermined stress or more to the front panel portion 13. There is.

  Next, while retracting the second slider 15 manually or pressing the second slider 15 against the projecting piece L1, the electronic device 10 is returned to the parallel state with respect to the rail-shaped structure L, and the second Attachment is performed by the urging force of the first slider 14 and the second slider 15.

  At that time, the stress applied by the operator is transmitted from the front panel section 13 to the rear surface of the housing where the first slider 14 and the second slider 15 are disposed through both the first circuit board 16 and the second circuit board 17. The stress is transmitted to each of the divided casings independently and almost uniformly.

  That is, the stress applied to the front panel portion 13 acts directly to the back surface of the housing without being attenuated.

  Thereby, even when the upper casing 11 and the lower casing 12 are thinned, stress transmission from the front panel portion 13 to the rear side of the casing is not hindered. It is very easy to reduce the thickness.

  In other words, the front panel unit 13 and the case divided into a plurality of cases are added from the operator by being firmly coupled via the circuit boards (the first circuit board 16 and the second circuit board 17, the same shall apply hereinafter). Since the stress is reliably transmitted from the front panel section 13 to the rear surface of the casing on which the pair of sliders (the first slider 14 and the second slider 15) are arranged via the circuit board, the lightweight and thin casing. It becomes easy to cope with the conversion.

  In particular, when the casing on the main body side of the electronic device 10 is divided into a plurality of layers so as to be stacked in the direction in which the rail-like structure L extends, the casing is not integrally formed into a box shape. For this reason, there is an original problem that efficient stress transmission cannot be obtained and it is extremely difficult to reduce the thickness and thickness of the housing. However, according to the present configuration, the problem can be easily solved.

  Further, in a state where only the back side of the casing of the electronic device 10 is attached to the rail-like structure L, the mounting component and the front panel unit 13 are held by both the first circuit board 16 and the second circuit board 17. Therefore, the casing itself is not deformed by the weight thereof, and the electronic device 10 is stably held even if the casing is thinned.

  Further, the stress acting on the front panel unit 13 from the operator is distributed from the front panel unit 13 to the first circuit board 16 and the second circuit board 17 and concentrated on the fitting portion between the housing and the front panel unit 13. Since it is less likely to act, it is possible to reliably prevent the front panel unit 13 from being separated from the housing or the side surface of the housing being bent and deformed.

  Further, after the front panel portion 13 is fitted to the end portion 11a of the upper housing 11 and the end portion 12a of the lower housing 12, the front panel portion 13 and the housing are coupled as described above. The housing of the electronic device 10 can be reliably coupled with a simple configuration without the need for a complicated configuration capable of withstanding the stress, such as a screw, bolt, adhesive, or other dedicated coupling member.

The technical scope disclosed in different embodiments, respectively.

  Next, another modified example will be described with reference to a schematic view of the state attached to the rail-like structure side L viewed from the back side.

  Finally, FIG. 14 (e) shows that the first casing 61a and the second casing 61b divided into two in the extending direction of the rail-like structure L are coupled by a movable slider 63 that can be moved forward and backward, and 1 shows an electronic device 60 in which a rail-like structure L is sandwiched between a fixed engagement portion 62 and a movable slider 63.
