Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a holder for holding and positioning various components and wiring materials arranged on a printed board.
[0002]
A circuit pattern for configuring a desired circuit function is formed on the printed board, and various electronic components and mechanical components are mounted and mounted.
In addition to such electronic components and mechanical components, photoelectric conversion elements and modules as optical circuits are mounted and mounted, and coaxial cables and electric wires for electrical wiring such as optical fibers, signal lines and power lines ( In this specification, these are collectively referred to as a wiring member), and electrical components, optical components, and the like associated therewith are arranged.
[0003]
Since such parts and wiring materials need to be positioned and fixed in place so that they do not move freely on the printed board, simple holders are positioned and held at the important points on the printed board surface. Is done.
[0004]
Relatively large parts such as modules are fixed by screwing or mechanically fixed by soldering and connecting many lead terminals to the circuit pattern. The relatively small parts that are connected are held by the holder because screwing requires space for them and troublesome work such as installation.
[0005]
[Prior art]
FIG. 15 shows a perspective view of such a conventional holder, in particular a cable holder. The cable holder 1 is a holding part 2 having a frame shape at the upper part, and the upper sides thereof are arm parts 3 and 4 extending from left to right toward the center, and are configured to overlap each other at the center part. It is relatively thin so that it can be elastically deformed, and can pass through the cable 5 by being pushed down.
[0006]
The lower portion of the cable holder 1 has a leg 6 that extends downward from the center of the upper frame shape and is inserted into the through-hole 9 of the printed board 8 so that it is directed upward from the tip of the leg 6 (not shown). The shaped locking piece is expanded by elasticity, and the locking piece is engaged with the back surface of the printed board 8 so that the retaining position and the standing posture are maintained.
[0007]
The cable holder 1 is made of an integral synthetic resin molded product having elasticity and appropriate hardness, and is erected at appropriate intervals and positions along the direction in which the cable 5 extends, and is held in the holding portion 2. By inserting the cable 5, the cable 5 is positioned and held so that it can be removed.
[0008]
However, although the cable holder 1 can simply hold the cable 5 inserted, as is apparent from the drawing, for example, it is not possible to hold a component attached to the cable 5 so that it can be inserted and removed.
[0009]
FIG. 16 is a perspective view of the holder 11 that can hold a component. A comparatively thin metal plate is punched and bent by press forming, and the upper holding portion 12 is formed as an upstanding surface 14 in which both sides of the substrate 13 are parallel in the upward direction, and the middle of each upstanding surface 14 is separated by a notch 15. ing.
[0010]
A narrow insert piece 17 at the tip of the board 13 is inserted into the through-hole 9 of the printed board 8 as a leg piece 16 which is bent downward in parallel on both sides of the board 13, and the end face of the step portion of the leg piece 16 is printed. The inserted piece 17 is in a standing posture in contact with the surface of the board 8 and is fixed by being soldered to a copper foil pattern on the back surface of the printed board 8 (not shown).
[0011]
One optical fiber 21 is introduced from one end into a synthetic resin container, and two optical fibers 22 are introduced from the other end, and optically coupled inside or optically demultiplexed. An optical component 23 having a function is inserted and arranged in the holding portion 12 of the holder 11 as shown in the figure.
[0012]
In this case, the holder 11 is erected at two positions with a gap therebetween, and is fitted into both the holding portions 12. A synthetic resin bundled wire band (trade name tie wrap) 24 is wound from the lower surface of the substrate 13 so as to pass through the notch 15 so as to surround the upper side of the optical component 23 and tighten. In this way, the optical component 23 is fixedly held.
[0013]
[Problems to be solved by the invention]
The above-described conventional holder shown in FIG. 15 needs to have a through-hole 9 in the printed board 8, and therefore, in the case of a printed board having a multi-layer structure, there is a limitation in providing the through-hole. It cannot be provided at any position.
[0014]
Since the cable 5 is inserted and held in the holding unit 2, the cable 5 cannot be held in a tightened state, and the optical component 23 can be held in a similar state so that it can be inserted and removed. Can not.
[0015]
Also in the holder 11 of FIG. 16, the through-hole 9 must be provided in the printed board 8, and means for soldering and fixing on the back side is also necessary. In order to hold the optical component 23, the bundle band 24 and a tool for tightening the bundle are required. If the problem is that the optical component 23 is excessively tightened or the optical component 23 needs to be removed, the bundle band 24 is attached. Cutting and removing and reattaching requires a new bundle band 24 and its attaching work.
[0016]
In view of the conventional problems as described above, the present invention is small and can be directly attached to the printed board surface, and is not limited to any of wiring materials or parts, and has good handleability. Thus, it is an object of the present invention to provide a versatile holder.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the holder of the present invention will be described in detail with reference to the drawings by embodiments based on the configuration gist. For ease of understanding, the same parts are denoted by the same reference numerals throughout the drawings for convenience.
[0033]
FIG. 1A is a perspective view of a first embodiment of the holder of the present invention. 2A is a front view, FIG. 2B is a side view, and FIG. 2C is a plan view. 2 is shown in a state where an optical component through which the optical fiber penetrates is held, and FIG. 3 (a) shows a perspective view thereof.
[0034]
The holder 31 is a belt-like thin plate made of an elastic metal plate, for example, a stainless steel plate, phosphor bronze plate, etc. having a spring property. 34, 34.
[0035]
The front end side of the standing surface 34 is folded back toward the mounting surface 32 so as to be inside the both standing surfaces 34, 34, and the folded portion 35 is formed on a flat surface 36 parallel to the mounting surface 32. By being folded in this manner, the opening 37 and the opposing holding part 38 are formed.
[0036]
As shown in the drawing, the holding portion 38 is formed with a curved portion 39 so as to approach the upright surface 34 side, and both ends 41 are again approached by the inclined surface 42 and terminated. Since it is like this, the space | interval of the bending part 39 is spaced apart rather than the space | interval of the opening part 37, and the both front-end | tips 41 are set to the closest state.
[0037]
The hatched portion shown in FIG. 1A is a portion 43 where solder plating is applied. When the material is a phosphor bronze plate other than a stainless steel plate, a surface treatment such as nickel plating is applied to the entire surface in advance.
[0038]
Referring to FIG. 1B, the main part of the printed board 45 is shown, and the holder mounting mounting pattern 46 is formed in a rectangular shape with copper foil. The mounting surface 32 of the holder 31 is placed on the holder mounting pattern 46 as shown by a two-dot chain line.
[0039]
Although not shown in the drawing, an appropriate amount of a known solder paste is supplied in advance by screen printing, for example, by heating the entire printed board 45 to melt the solder by heating the entire printed board 45 (not shown). Can be attached.
[0040]
This can be performed simultaneously with mounting and mounting of an electric circuit component (not shown), or can be individually soldered with a soldering iron or the like.
[0041]
As is apparent from the figure, the long side of the holder mounting pattern 46 protrudes and intersects with the width of the mounting surface 32 as appropriate, so that the solder (not shown) covers the mounting surface 32 and is surely secured. A fixed state can be obtained.
[0042]
Referring to FIG. 2 and FIG. 3 (a), the optical component 52 through which the optical fiber 51 penetrates, for example, a connection in a so-called splice connection state in which both end surfaces of a pair of optical fiber cores are brought into contact with each other for fusion connection The cover part is covered and protected, and the cover part as the optical component 52 that is mechanically reinforced and protected is inserted into the holding part 38 of the holder 31 with the opening 37 widened. Status is shown.
[0043]
The state in which the optical component 52 is inserted into the holding portion 38 is stably held from both sides so as to be sandwiched between the inclined surface 42 and the inclined surface on the opening 37 side, as shown in FIG. Is done.
[0044]
Although such an optical component 52 is a connection portion of the optical fiber 51, other similar optical components can be held without being limited to this. In order to insert the optical component 52 into the holding portion 38, the opening 37 can be easily expanded and inserted by being pushed against the opening 37.
[0045]
The expansion of the holding portion 38 can be elastically deformed from the bent portion 33, the upright surface 34, the folded portion 35, the opening portion 37, and the holding portion 38, so that it is flexible and has a wide range of expansion without difficulty. Therefore, it can meet various requirements without being particular about the size and shape of the optical component.
[0046]
In addition to being able to mount the holder 31 directly on the surface of the printed board 45, the mounting portion 38 is formed by being folded between the upright surfaces 34, so that the mounting height is kept to a minimum. Therefore, the mounting height of the entire printed board 45 can be reduced.
[0047]
FIG. 3B shows a state in which a plurality of optical fibers 51 are bundled and surrounded by a synthetic resin enclosure 53. The surrounding body 53 may be a cylindrical body provided with a cut 54, or may be a wound sheet. In particular, a flexible sheet can be wrapped.
[0048]
It is preferable to make the surrounding body 53 rubbery because a large frictional force acts and is prevented from moving. In this way, the holder 31 can be held by changing the number of the optical fibers 51 that are wiring members as appropriate within a range.
[0049]
FIG. 4 is a front view of a second embodiment of the holder of the present invention. The holder 57 is a belt-like thin plate made of elastic metal plate, for example, a spring-like stainless steel plate, phosphor bronze plate, or the like. 34, 34.
[0050]
The front end side of the standing surface 34 is folded back toward the mounting surface 32 so as to be inside the both standing surfaces 34, 34, and the folded portion 35 is formed on a flat surface 36 parallel to the mounting surface 32. By being folded in this manner, the opening 37 and the opposing holding part 38 are formed.
[0051]
As shown in the drawing, the holding portion 38 is formed with a curved portion 39 so as to approach the upright surface 34 side, and both ends 41 are again approached by the inclined surface 42 and terminated. Since it is like this, the space | interval of the bending part 39 is spaced apart rather than the space | interval of the opening part 37, and the both front-end | tips 41 are set to the closest state.
[0052]
The above configuration is the same as that of the holder 31 of FIG. 1A, and a solder plating portion 43 for soldering and fixing to the holder mounting pattern 46 of the printed board 45 is provided on the mounting surface 32 side. It is the same as being done.
[0053]
As shown in the figure, the holder 57 is relatively flexible around the holding portion 38. For example, an elastic material 58 made of a synthetic resin material having thermoplasticity is immersed or applied in a heated molten state. To be formed. Therefore, the holding portion 59 of the holder 57 is configured to be provided with the elastic material 58 in this way.
[0054]
By applying such an elastic material 58, the elastic material 58 is softly held while being familiar with a held object such as a component or a wiring material.
[0055]
By using a material having rubber properties, it is possible to prevent the material from easily moving due to the frictional force. The elastic material 58 does not need to be applied to the entire periphery of the holding portion 38, but may be applied to at least the opposing surfaces. Other operations and effects are the same as those described with reference to FIGS.
[0056]
FIG. 5A is a perspective view of a third embodiment of the holder of the present invention. The holder 61 is a belt-like thin plate made of elastic metal plate such as a stainless steel plate, phosphor bronze plate, etc. having a spring property, and a standing surface on which both sides of the flat mounting surface 32 are bent by the bent portions 33 and parallel. 34, 34.
[0057]
The front end side of the standing surface 34 is folded back toward the mounting surface 32 so as to be inside the both standing surfaces 34, 34, and the folded portion 35 is formed on a flat surface 36 parallel to the mounting surface 32. By being folded in this manner, the opening 37 and the opposing holding part 38 are formed.
[0058]
As shown in the drawing, the holding portion 38 is formed with a curved portion 39 so as to approach the upright surface 34 side, and both ends 41 are again approached by the inclined surface 42 and terminated. Since it is like this, the space | interval of the bending part 39 is spaced apart rather than the space | interval of the opening part 37, and the both front-end | tips 41 are set to the closest state.
[0059]
The above configuration is the same as that of the holder 31 of FIG. 1A, and a solder plating portion 43 for soldering and fixing to the holder mounting pattern 46 of the printed board 45 is provided on the mounting surface 32 side. It is the same as being done.
[0060]
As shown, the holder 61 is provided with a first elastic material 62 having a convex shape on the opening 37 side of the holding portion 38 and a second elastic material 63 having a convex shape at the tip 41 portion. . As is clear from the figure, the convex shape of the first elastic member 62 is set to be smaller than the convex shape of the second elastic member 63.
[0061]
Each of the first and second elastic members 62 and 63 has a cylindrical shape that penetrates the inner plate in the direction crossing the thin plate material of the holder 61, and is preferably made of a rubber material.
[0062]
Such elastic materials 62 and 63 can be manufactured by sandwiching a thin plate material of the holder 61 in a mold and fusing the material. Therefore, the actual holding portion 65 of the holder 61 has a configuration provided with such elastic materials 62 and 63.
[0063]
By applying such elastic materials 62 and 63, the material is compatible with objects such as components and wiring materials to be held and is held flexibly, so that it is held in a stable state with cushioning without difficulty. . By using a rubbery material, it is possible to suppress the movement easily due to the frictional force.
[0064]
FIG. 5B shows a state in which the optical component 52 described with reference to FIG. 2 is held. The optical component 52 is indicated by a two-dot chain line for easy understanding of the relationship of the holder 61. It is.
[0065]
Although it is not clear in the figure, the optical component 52 is held in contact with only the first elastic member 62 and the second elastic member 63, and the contact part is a line contact in the longitudinal direction of four surroundings. A stable posture is maintained by surface contact by being pressed by the elastic restoring force 61.
[0066]
The above is clearer with reference to the state mounted on the printed board 45 shown in FIG. 6A is a front view, FIG. 6B is a side view, and FIG. 6C is a plan view.
[0067]
The small size of the first elastic member 62 facilitates the passage of the opening 37 in order to hold the optical component 52, and the second elastic member 63 larger than this may have a flexible tip 41. Thus, the optical component 52 can be prevented from passing and the holding state can be made stable.
[0068]
Needless to say, the holder 61 can hold not only the optical component 52 but also the optical fiber and other components and wiring materials.
[0069]
The elastic materials 62 and 63 do not allow the thin plate material to pass therethrough, and it is only necessary to give a convex shape to at least the opposing surfaces. Other operations and effects of the holder 61 are the same as those described with reference to FIGS.
[0070]
7A and 7B show a fourth embodiment of the holder of the present invention. FIG. 7A is a perspective view and FIG. 7B is a plan view. The holder 71 is made of a band-like and elastic metal, for example, a stainless steel plate, a phosphor bronze plate, and the like, and both sides of the flat mounting surface 72 are bent by the bent portions 33 and formed on the standing surfaces 34 and 34 in parallel.
[0071]
The leading end side of the standing surface 34 is folded back toward the mounting surface 72 so as to be inside the both standing surfaces 34, 34, and the folded portion 35 is formed on a flat surface 36 parallel to the mounting surface 72. By being folded in this manner, the opening 37 and the opposing holding part 38 are formed.
[0072]
As shown in the figure, the holding portion 38 is formed with a curved portion 39 so as to approach the upright surface 34 side, and both ends 41 are again approached by the inclined surface 42 and terminated. Since it is like this, the space | interval of the bending part 39 is spaced apart rather than the space | interval of the opening part 37, and the both front-end | tips 41 are set to the closest state.
[0073]
A convex first elastic material 62 is provided on the opening 37 side of the holding portion 38, and a convex second elastic material 63 is provided on the tip 41 portion. The convex shape of the first elastic material 62 is set smaller than the convex shape of the second elastic material 63.
[0074]
Each of the first and second elastic members 62 and 63 has a cylindrical shape that penetrates the inner plate in the direction crossing the thin plate material of the holder 71, and is preferably made of a rubber material. Therefore, the actual holding portion 65 of the holder 71 has a configuration provided with such elastic materials 62 and 63.
[0075]
The above configuration is the same as that of the holder 61 of FIG. 5, but the holder 71 has projections 73 in the lateral direction on the mounting surface 72 as shown in the figure, and protrudes on both sides as shown in FIG. Is done. On both surfaces of the attachment surface 72, a solder plating portion 43 for soldering and fixing to the holder mounting mounting pattern 46 of the printed board 45 is provided.
[0076]
By forming such protrusions 73, when soldering to the holder mounting mounting pattern 46, heat is less concentrated and diffused in the portions of the protrusions 73, so that the solder is melted quickly. Since the temperature tends to be high, the flow of solder is improved, and a reliable soldering state is obtained mainly for the protrusion 73.
[0077]
The operation and effect of holding an object such as a component or a wiring material of the holder 71 is the same as described with reference to FIGS.
FIG. 8 is shown in a perspective view of a fifth embodiment of the holder of the present invention. The holder 81 is made of a band-like and elastic metal, for example, a stainless steel plate, a phosphor bronze plate, and the like, and both sides of the flat mounting surface 82 are bent by the bent portions 33 and formed on the standing surfaces 34 and 34 in parallel.
[0078]
The leading end side of the standing surface 34 is folded back toward the mounting surface 82 so as to be inside the both standing surfaces 34, 34, and the folded portion 35 is formed on a flat surface 36 parallel to the mounting surface 82. By being folded in this manner, the opening 37 and the opposing holding part 38 are formed.
[0079]
As shown in the figure, the holding portion 38 is formed with a curved portion 39 so as to approach the upright surface 34 side, and both ends 41 are again approached by the inclined surface 42 and terminated. Since it is like this, the space | interval of the bending part 39 is spaced apart rather than the space | interval of the opening part 37, and the both front-end | tips 41 are set to the closest state.
[0080]
A convex first elastic material 62 is provided on the opening 37 side of the holding portion 38, and a convex second elastic material 63 is provided on the tip 41 portion. The convex shape of the first elastic material 62 is set smaller than the convex shape of the second elastic material 63.
[0081]
Each of the first and second elastic members 62 and 63 has a cylindrical shape that penetrates the inner plate in the direction crossing the thin plate material of the holder 81, and is preferably made of a rubber material. Therefore, the actual holding portion 65 of the holder 81 has a configuration provided with such elastic materials 62 and 63.
[0082]
The above configuration is the same as that of the holder 61 of FIG. 5, but the holder 81 reduces the contact area with the holder mounting pattern 46 on the printed board 45 on the side of the mounting surface 82 as shown in the figure. A notch, that is, a T-shaped protrusion 83 formed by an L-shape facing each other, is formed on both sides.
[0083]
Therefore, the T-shaped protrusion 83 is not protruded from both sides of the attachment surface 82. Solder plating portions 43 for soldering and fixing to the holder mounting mounting pattern 46 of the printed board 45 are provided on both surfaces of the mounting surface 82.
[0084]
By forming such a T-shaped protrusion 83, when soldering to the holder mounting pattern 46, heat is applied to the T-shaped protrusion 83 portion having a small contact area with the holder mounting pattern 46 due to the notch. Therefore, since the melting of the solder is fast, the melting temperature tends to be high, the flow of the solder is improved, and the T-shaped protrusion 83 is mainly secured.
[0085]
The action and effect of holding an object such as a component or wiring material of the holder 81 is the same as described with reference to FIGS.
FIG. 9 is a development view according to the method for manufacturing the strip-shaped metal thin plate shown in FIG. The strip-shaped metal thin plate 85 is obtained by punching out the above-described material or an appropriate material that can be used with a press device or the like.
[0086]
That is, a T-shaped projection 83 is formed in the center by L-shaped notches 86 facing each other on both sides of the center. As a matter of course, the T-shaped protrusion 83 does not protrude from the side of the strip-shaped metal thin plate 85 as is apparent from the drawing.
[0087]
A rectangular hole 87 extending in the width direction is provided on both ends of the strip-shaped metal thin plate 85, and semicircular cuts 88 are formed at positions on both sides, which are located closer to the center than that.
[0088]
FIG. 10 shows a manufacturing method for applying the first elastic material 62 and the second elastic material 63 shown in FIG. After the strip-like thin metal plate 85 obtained as shown in FIG. 9 is subjected to a surface treatment such as appropriate plating, as shown in the plan view of FIG. Install the required number in parallel.
[0089]
Next, as shown by a two-dot chain line in the side view of FIG. 2B, the first elastic member 62 and the second elastic member 63 are arranged so as to cross the width direction of the strip-like thin metal plates 85 arranged in parallel. For example, a synthetic rubber material having an appropriate hardness is cast into a continuous shape using a mold.
[0090]
The first elastic member 62 covers the semicircular cut 88 and the second elastic member 63 covers both ends and the rectangular hole 87, respectively, so that the illustrated state is obtained. It is done.
[0091]
The first and second elastic members 62 and 63 are separated from each other by being cut between adjacent strip-like metal thin plates 85 as they are taken out from the molding apparatus or as they are.
[0092]
Thereafter, the holder 81 is completed by bending and finishing it into a shape as shown in FIG. 8 using an appropriate press die.
As described above, the manufacturing method for applying the first elastic material 62 and the second elastic material 63 is not limited to the above, and is also applied to the holders 61 and 71 shown in FIGS. is there.
[0093]
FIG. 11 is a perspective view showing a state in which the holder 81 shown in FIG. 8 is mounted on the printed board 45 and the optical component 91 is inserted and held. That is, the holder 81 is arranged in the illustrated state on the two holder mounting / mounting patterns 46 formed at predetermined intervals in the series direction, and the mounting surface 82 is soldered and mounted.
[0094]
In the optical component 91, a pair of optical fibers 51 are introduced on both sides of a relatively long cylindrical main body 92, and the holding state thereof will be described with reference to FIG. Thus, a stable holding state can be achieved without difficulty, and a position close to the surface of the printed board 45 can be achieved to reduce the mounting height.

As is apparent from the figure, the optical component 52 is held in contact with only the first elastic member 62 and the second elastic member 63, and the contact part is a line contact in the longitudinal direction of the four surroundings. A stable posture is maintained by surface contact by being pressed by the elastic restoring force 101.
[0115]
Since the first elastic material 62 is provided on the inclined surface 103 on the opening 37 side, the pressing force that presses the optical component 52 against the surface of the inclined surface 103 acts appropriately and stably.

The small size of the first elastic material 62 makes it easy to expand and pass the opening 37 in order to hold the optical component 52, and the second elastic material 63 larger than this may be flexible on the tip 41 side. Thus, the optical component 52 is prevented from passing and the holding state is stable.
[0117]
Of course, it is possible to hold not only the optical component 52 but also the optical fiber, other components, and the wiring material in the holder 101, as a matter of course.
[0118]
Also for the holder 101, the mounting surface 102 is provided with the projection 73 as described with reference to FIG. 7, and the contact area with the pattern on the printed board surface as described with reference to FIGS. For example, it is possible to apply a notch 86 for reducing the above-mentioned.
[0119]
Furthermore, as in the embodiment described above, the elastic members 62 and 63 do not penetrate through the thin plate material, but it is also possible to apply a convex shape to at least the opposing surfaces. is there.
[0120]
Needless to say, the flat surface 36 can be automatically mounted.
[0121]
