Description

  The present invention relates to a member connection structure capable of easily connecting two members adjacent to each other, releasing a connection state, and separating the two members, and an electronic device including the member connection structure.

  Conventionally, for example, as shown in FIG. 6, as is apparent from the arrangement relationship in the one-side recessed portion 116 of the unit device 111 located on the left side, the connecting metal fitting 132 is protruded from the rear end 135 a of the hook portion 135. There is a structure that is stably stored and held by abutting (see, for example, Patent Document 1).

  When the unit devices 111 are connected to each other, the other side opening edge 127 of the other side recessed portion 126 of the one unit device 111 located on the left side and the one side recessed portion 116 of the other unit device 111 located on the right side. It arrange | positions so that the one side opening edge 117 may mutually face.

  After the unit devices 111 and 111 are arranged adjacent to each other in such a positional relationship, the connecting fitting 132 that is stably housed and held in the other one-side recessed portion 116 located on the right side is connected to the squeezing operation portion. An external force is applied such that 138 is rubbed with fingers and moved to the left.

  The connection fitting 132 that is loosely inserted into a support shaft portion (not shown) into which the screw 120 is inserted and is fixed to be difficult to remove by the head portion of the screw 120 is relatively subjected to external force. After riding on the top end of the protruding part 121 under the condition that it is difficult to move, it gets over this and passes through the one side opening edge 117 and the other side opening edge 127 in the other side recessed part 126 of the left one unit device 111. Get in.

  The other recessed portion 126 of the one unit device 111 located on the left side comes into contact with the inner end 135a of the hook portion 135 when the inserted fitting 132 is smoothly moved to a rotation angle of approximately 90 degrees. Since the latching convex part 129 for latching this is provided, the movement of the connecting fitting 132 can be stopped.

  In addition, the other recessed portion 126 rides in a state where it is relatively difficult to move by receiving an external force, and the hook portion 135 is hooked on the hooking convex portion 129 when it gets over it. Since the projecting portion 130 is provided, the latched state can be stably maintained.

  That is, according to the present invention, the unit device 111 is simply rotated separately in the direction of the one unit device 111 located on the left side of the connecting bracket 132 provided on the upper and lower surfaces of the other unit device 111 located on the right side. 111 can be connected easily and reliably.

  In addition, the unit devices 111 and 111 can be connected to each other by reversing the connecting device 132 and returning the connecting fitting 132 to its original position.

  However, various problems arise in the above-described member connection structure.

  For example, the unit device 111 requires a separate screw 120 for rotatably supporting the connection fitting 132, and thus the number of members increases.

  In addition, the substantially racetrack-shaped connection fitting 132 is brought close to one semicircular side and is pivotally supported by the screw 120, so that two members connected to each other (in the conventional technical description, the unit device 111). (Equivalent) requires a recessed space for storing the connecting metal both when connected and when disconnected (when released).

  Furthermore, since a space necessary for moving the connecting metal fitting 132 (rotating around the screw 120) is also required, it is required to be light and thin so that the surface area of the housing of the unit device 111 is reduced. In this case, the design margin is small, so it is unsuitable (difficult to apply).

  The present invention has been made in view of the above-mentioned reasons, and the purpose thereof is that even in a narrow space where the surface area of the side surface to which the connecting fittings of the two members connected to each other are attached is limited, the two An object of the present invention is to provide a member connection structure having a simple structure and an electronic device including the member connection structure that can not only easily connect members but also easily release and separate the connection state.

  According to the member connection structure according to the present invention, two members including two members adjacent to each other and a connecting body rotatably attached to an insertion hole formed in any one of the members. It is a member connection structure which can be connected, Comprising: As for a connection object, the convex part for axial support inserted in the insertion hole of one member, and the 1st convex part for locking of one member are inserted. It has an opening and a second opening into which the second protrusion for locking the other member is inserted, and the second opening has an opening in a predetermined range on the outer edge side. .

  Thereby, when connecting two members mutually, even if it is the narrow space where the surface area of the side surface which attaches the connection body of two members was restricted, those two members can be connected easily.

  That is, despite the simple configuration, the two members can be efficiently separated and connected in a limited narrow space.

  Even when the connection state between the two members is released and separated, the connection body is maintained in a state where it is attached to one of the members, so there is no concern about contamination due to loss or dropout of the connection body. One member can be easily separated or joined (hereinafter referred to as a detaching operation).

  Moreover, according to the member connection structure concerning this invention, in addition to the said structure, the 1st opening part of a connection body is a substantially circular-arc-shaped opening along a rotation direction, Comprising: The connection state of two members is carried out. It is preferable that the opening width is widened at a location corresponding to two positions of a connection position that can be maintained and a release position where the connection state between the two members can be released.

  As a result, the opening width is widened at a position corresponding to two positions of a connection position where the connection state between the two members can be maintained and a release position where the connection state between the two members can be released. When the first protrusion for locking fits in, the mutual interference becomes weaker than in the state where the opening is not widened, so that the locked state is easily held and rotation is suppressed.

  As a result, each state can be easily maintained in either a state where the two members are connected or a state where the connection is released (a state where the two members can be separated, hereinafter the same).

  That is, since the coupling body is maintained in the locked state in either the coupled state or the released state, the coupling body does not rotate carelessly and can be easily attached and detached.

  Further, according to the member connection structure according to the present invention, in addition to the above-described configuration, the shaft support convex portion of the connection body is an arc on the inner peripheral side of the first opening or the first opening excluding the connection position and the release position. It is preferable to have a pair of flexible locking portions that extend along the rotation center line located at substantially the center of any one of the arcs on the outer peripheral side of the portion and face each other.

  As a result, the space occupied by the connecting body on the two members does not change greatly even if the connecting body is rotated from the connected state to the released state around the pivot support for the connecting body. Even so, it is possible to efficiently separate and connect the two members.

  In addition, if a key-shaped hook is formed on the distal end of the pair of flexible locking portions toward the outer side, it is easy to insert into the insertion hole of one member, and it is connected from one member. It is possible to effectively prevent the body from falling off.

  Further, according to the member connection structure according to the present invention, in addition to the above configuration, the connection body has at least one rotation protrusion on the surface opposite to the surface on which the shaft support protrusion is formed, It is preferable that the rotation convex portion is extended from the rotation center line along a substantially radial direction on an orthogonal plane orthogonal to the rotation center line.

  Thereby, for example, it becomes easy to apply turning force to the connecting body in a direction substantially orthogonal to the radial direction using a tip of a flat-blade screwdriver or a coin, so that the rotation from the connected state to the released state can be easily performed. .

  In addition, according to the electronic device including the member connection structure according to the present invention, the electronic device includes the member connection structure having any one of the above-described configurations.

  Thereby, when connecting two members mutually, even if it is the narrow space where the surface area of the side surface which attaches the connection body of two members was restricted, those two members can be connected easily.

  That is, despite the simple configuration, the two members can be efficiently separated and connected in a limited narrow space.

  In addition, even when the connection between the two members is released and separated, the connection body is maintained in a state of being attached to either one of the members, so there is no concern about contamination due to loss or dropout of the connection body. The member can be easily attached and detached.

  According to the member connecting structure and the electronic device including the member connecting structure according to the present invention, the two members can be easily connected even in a narrow space where the surface area of the side surfaces of the two members connected to each other is limited. Or can be easily separated by releasing the connected state.

  Hereinafter, in order to describe an embodiment of the present invention, it will be described with reference to the drawings.

  FIG. 1 is an overall perspective view of the connection terminal component according to the embodiment of the present invention as seen from the diagonally upper front side, and FIG. 2A is a partially enlarged perspective view of the connection terminal component with the coupling body removed. (B) is a perspective view of the front side of the single unit of the coupling body, FIG. 2 (c) is a perspective view of the rear side of the single unit of the coupling body, and FIG. FIG. 3B is a rear view in the Y direction showing a state where the lower terminal block is connected, and FIG. 3B is a Y direction showing a state where the connection between the upper terminal block and the lower terminal block of the connection terminal component is released. 4 is a front view of a single connector, FIG. 5 (a) is an overall perspective view of an electronic device in which the connection terminal parts in the present embodiment are arranged on the upper surface side, and FIG. ) Is a side view of one side of the electronic device, and FIG. 5C is a bottom view of the electronic device (surface on the mounting side to the backplane).

  First, the connecting terminal component 10 in FIG. 1 is a resin material that constitutes a main body portion and can ensure appropriate insulation, for example, PC (polycarbonate), modified PPE (modified polyphenylene ether), PF (phenol), PBT (polybutylene). An upper terminal block 11 molded from a thermoplastic resin material such as terephthalate and a lower terminal block 12 made of the same material are disposed adjacent to each other at a boundary K.

  Here, in order to facilitate the following description, the width direction of the connection terminal component 10 is the X direction, the depth direction coinciding with the longitudinal direction is the Y direction, and the height direction (vertical direction) is the Z direction. The direction and the Z direction are defined as directions orthogonal to each other.

  The terminal cover 13 has a comb shape when viewed obliquely from the upper side (insertion side of the crimp terminal 14), and slides inclined at a predetermined angle with respect to the Y direction at both ends bent downward at a right angle. It has a pair of flexible locking portions 13a extending along the direction and facing each other.

  Note that the outer conductors, that is, the three sets of round crimping terminals 14 in the horizontal direction (X direction) in FIG. 1 are arranged close to each other in the horizontal direction, but the crimping portions 14a of the respective crimping terminals 14 are arranged. The external lead wires and the ends thereof that are pressed and electrically connected to each other are omitted.

  Here, the external lead wire may be, for example, either a lead wire whose other end is connected to another external electronic device or a lead wire connected to another crimp terminal 14 in the same connection terminal component 10. I do not care.

  Further, as is apparent from FIG. 1, the three sets of crimp terminals 14 are grouped as one group, and when viewed from the diagonally upper side (insertion direction side of the crimp terminals 14), one comb-shaped terminal cover 13 is provided for each. The crimp terminal 14 is covered for each group of three sets.

  Since a total of eight stages (eight groups) of crimp terminals 14 are connected to each of the plurality of terminals 15 along the Y direction, the total number of connections is 27.

  As described above, the plurality of terminals 15 are integrally inserted into the upper terminal block 11 and the lower terminal block 12 by press-fitting, but the longitudinal direction of the upper terminal block 11 and the lower terminal block 12 is set. Is placed in a direction that matches the Y direction, the insertion direction of the terminal 15 matches the Z direction.

  In this state, the arrangement direction of the plurality of terminals 15 coincides with the Y direction.

  That is, since the insertion direction (Z direction) of the terminals 15 is in a positional relationship orthogonal to the arrangement direction, it is paraphrased that a plurality of terminals 15 are inserted at substantially equal intervals along the arrangement direction (Y direction). May be.

  And the connection body 16 comprises a part of the structure which connects two members mutually adjacent, ie, the upper side terminal block 11 and the lower side terminal block 12, but the near side surface (front) in a Y direction and It is rotatably attached so as to straddle each boundary K of the back side surface (back surface) (refer to FIG. 5 (a) to FIG. 5 (b) for the back surface side).

  Next, with reference to FIG. 2A to FIG. 2C, only the coupling body 16 is separated from the upper terminal block 11 and the lower terminal block 12 which are adjacent to each other on the front side surface (front surface). That is, the state before they are combined will be described.

  In addition, about the side surface of the back side of a Y direction, since it is the same as that of the structure demonstrated below, description is abbreviate | omitted.

  Further, in FIGS. 2A to 2C, the rotation center line S of the coupling body 16 is shown by a one-dot chain line corresponding to the respective drawings, but the upper terminal block 11 and the lower terminal block 12. Of course, in the state in which the connecting body 16 is coupled, the rotation center lines S are in a positional relationship that coincides on a straight line.

  First, the upper terminal block 11 and the lower terminal block 12, which are two members adjacent to each other, are adjacent to each other side by side in the Z direction as shown in FIG. 2A, and are located in parallel with the XY plane. Both are in contact with each other.

  Here, although the connection body 16 is shown in a state where it is removed from the upper terminal block 11 and the lower terminal block 12, the connection body 16 is provided with a shaft support convex portion 16 a (see FIG. 2C) on the lower side. By being inserted into the circular insertion hole 12a of the terminal block 12, the terminal block 12 is rotatably attached.

  Next, as shown in FIG. 2 (b), the connecting body 16 is provided on the side surface of the lower terminal block 12 and the shaft support convex portion 16 a that is inserted into the insertion hole 12 a of the lower terminal block 12. Includes a first opening 16b into which a columnar locking first convex portion 12c that is erected on the bottom surface of a concave portion 12b that accommodates the connecting body 16 and is formed to be rotatable, and the upper terminal block 11. And a second opening portion 16c into which a substantially arc-shaped locking second convex portion 11a is inserted and fitted.

  Further, the second opening 16c of the connecting body 16 has an opening 16d in a predetermined range on the outer edge side.

  As will be described in detail later, the first opening 16b of the coupling body 16 is an arc-shaped opening along the rotation direction (the direction indicated by the arc-shaped arrow M) about the rotation center line S. There are two positions: a connection position P1 where the upper terminal block 11 and the lower terminal block 12 can be maintained in a connected state, and a release position P2 where the connection state between the upper terminal block 11 and the lower terminal block 12 can be released. The opening width is widened at a location corresponding to (P1, P2).

  Further, the connecting body 16 has a rotating convex portion 16e for rotating clockwise and a rotating convex portion 16f for rotating counterclockwise.

  The pivoting convex part 16e and the pivoting convex part 16f are both substantially radial from the pivoting center line S on the orthogonal plane orthogonal to the pivoting center line S from the pivoting center line S indicated by the alternate long and short dash line. It extends along the radial direction H toward the front.

  Further, as shown in FIG. 2 (c), the shaft support convex portion 16a of the connecting body 16 has the inner circumference side arc AI or the first of the first opening portion 16b excluding the connecting position P1 and the releasing position P2. The opening 16b has a pair of flexible locking portions 16ab extending along the rotation center line S located at the approximate center of any one of the outer peripheral arcs AO and facing each other.

  Further, the outer peripheral surfaces of the pair of flexible locking portions 16ab are tapered so as to be conically narrowed toward the tip, and each flexible locking portion 16ab has a key shape as a whole. The portion 16a is easily inserted into the insertion hole 12a of the lower terminal block 12, and is difficult to come out after being inserted.

  Next, with reference to FIG. 3A, a state in which the upper terminal block 11 and the lower terminal block 12 are coupled by the connecting body 16 will be described.

  In addition, although this figure is a rear view on the opposite side to the front of the connection terminal component 10 demonstrated with reference to Fig.2 (a)-FIG.2 (c), the upper side terminal block 11 and a lower side terminal block The only difference is that the boundary K where the abutment 12 abuts is extended in an L-shape, the structure of the connecting body 16, the columnar locking first protrusion erected on the lower terminal block 12. The configurations of the substantially arc-shaped locking second convex portion 11a erected on the portion 12c and the upper terminal block 11 are exactly the same.

  Here, the latching second convex portion 11a of the upper terminal block 11 is inserted into the second opening 16c of the connecting body 16, and the hook portion 16g of the connecting body 16 (see FIGS. 2B and 4). Since the upper terminal block 11 cannot be separated in the vertical direction with respect to the lower terminal block 12, the locked state is maintained.

  On the other hand, the first opening 16b of the connecting body 16 is an arc-shaped opening along the rotation direction (the direction indicated by the arc-shaped arrow M in FIG. 2B) as described above, and its opening width. Is set to be slightly smaller than the diameter of the circle of the transverse cut surface of the cylindrical first convex portion 12c for locking, and therefore the first convex portion for locking at the connection position P1 where the opening width is widened. It is locked by 12c and a connection state is maintained.

  Next, with reference to FIG.3 (b), the state with which the coupling | bonding of the upper terminal block 11 and the lower terminal block 12 is cancelled | released and both can be isolate | separated is demonstrated.

  In this state, the rotating protrusion 16f (see FIG. 2B) of the connecting body 16 in the connected state is pressed counterclockwise with, for example, a flat-headed flathead screwdriver or coin, and the connecting body 16 Is released in the counterclockwise direction, and is locked by the first locking projection 12c at the release position P2 where the opening width of the first opening 16b is widened, and the released state is maintained. .

  In this released state, when the upper terminal block 11 is to be separated from the lower terminal block 12, the second protrusion 11a for locking the upper terminal block 11 is on the outer edge side of the second opening 16c of the coupling body 16. Since it passes through the open portion 16d (see FIGS. 2B and 4) formed in the predetermined range without any trouble, the locked state is easily eliminated.

  On the other hand, even when the coupling body 16 is separated, the coupling body 16 is maintained in a state in which the shaft support convex portion 16a is inserted into the insertion hole 12a of the lower terminal block 12 (attached state).

  Thereby, even at the time of separation, the upper terminal block 11 can be easily attached / detached without fear of foreign matter adhesion or contamination due to the loss or dropping of the connection body 16.

  As described above, the connected state of the upper terminal block 11 and the lower terminal block 12 is maintained in a state in which the locking first convex portion 12c is fitted and inserted into the connecting position P1 of the first opening 16b.

  On the other hand, the connecting body 16 is rotated counterclockwise, and the upper terminal block 11 and the lower terminal block are inserted in the state in which the locking first convex portion 12c is inserted into the release position P2 of the first opening 16b. 12 release states (separable states) are maintained.

  Moreover, what is necessary is just to rotate the connection body 16 clockwise so that it may be in the state of Fig.3 (a) from the state of FIG.3 (b) from a cancellation | release state.

  Next, with reference to FIG. 4, the opening part 16d formed in the outer edge side of the 2nd opening part 16c of the coupling body 16 mentioned above is demonstrated.

  The opening 16d of the second opening 16c in the coupling body 16 is formed within a predetermined range indicated by the arrow of the arcuate arrow R, and this range is the release position P2 of the first opening 16b and the rotation center. A point on the extension of the straight line L2 of the two-dot chain line connecting the line S to the position passing through the connecting body 16, and the point where the rotation center line S passes through the connecting body 16 with respect to the release position P2. It is preferably formed at a symmetrical position.

  The open portion 16d has a substantially arc shape in the clockwise direction when the rotation center line S is centered on a position passing through the connecting body 16, as indicated by an arc-shaped arrow R with arrows at both ends. And approximately 25 degrees in the counterclockwise direction (a total angle of approximately 50 degrees sandwiched between two broken lines).

  In addition, what is necessary is just to set this range suitably according to the circular arc length of the 2nd convex part 11a for latching of the substantially circular arc shape standingly arranged by the upper side terminal block 11. FIG.

  On the other hand, the hook portion 16g of the connecting body 16 is an extension of the one-dot chain line straight line L1 connecting the connecting position P1 of the first opening 16b and the position where the rotation center line S passes through the connecting body 16, and With respect to P1, the rotation center line S is preferably formed at a position that is point-symmetric with respect to the position passing through the connecting body 16.

  Then, it is preferable that the position is formed in a range of about 25 degrees clockwise with respect to the arc and about 25 degrees counterclockwise (an angle of about 50 degrees as a whole).

  Further, as described above, the first opening 16b of the connecting body 16 is a substantially arc-shaped opening along the rotation direction, and the connecting position P1 that can maintain the connecting state between the two members, and the two The opening width is widened at locations corresponding to two positions of the release position P2 where the connection state between the members can be released.

  Here, the opening width is defined as the width of the opening in the direction in which the rotation center line S passes through the connecting body 16 in the direction of centrifugation from the reference, and the opening width at the connecting position P1 is on the straight line L1 of the one-dot chain line. It is assumed that the opening width at the release position P2 is the width of the opening on the two-dot chain line straight line L2.

  That is, since the opening width is set to be slightly larger than the diameter of the circle of the transverse cut surface of the cylindrical first convex portion 12c for locking, the opening portion that is not widened when engaged at that position. Since the mutual interference is weaker than in the state located at, the locked state is easily maintained and the rotation is suppressed.

  Next, with reference to FIG. 5A to FIG. 5C, the connection terminal component 10 described above is disposed on the upper side of the electronic device 20 used in the instrumentation field, and the main body is disposed on the lower side thereof. The state fixed with the hook of the side surface of the housing | casing 20a is demonstrated.
