DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holder for holding and positioning various components and wiring members disposed on a printed board.

[0002] On a printed circuit board, a circuit pattern for constituting a desired circuit function is formed, and various electronic parts and mechanical parts are mounted and mounted. In addition to such electronic parts and mechanical parts, photoelectric conversion elements and modules as optical circuits are also mounted and mounted, and coaxial wires and electric wires (such as optical fibers, signal wires, and power wires) for electrical wiring. In this specification, these are collectively referred to simply as wiring materials), and electrical components, optical components, and the like accompanying the components are arranged.

Since it is necessary to position and fix such components and wiring members at predetermined positions so as not to move freely on the printed board, a simple holder is positioned and arranged at a key position on the printed board surface. This is held.

[0004] Relatively large components such as modules are fixed by screws or mechanically fixed by connecting a large number of lead terminals to a circuit pattern by soldering. Relatively small parts connected to the wiring member are held by the holder because screwing requires space for the parts and troublesome work such as mounting.

2. Description of the Related Art FIG.
In particular, the cable holder is shown in a perspective view. The upper part of the cable holder 1 is a frame-shaped holding part 2, the upper parts of which are arm parts 3 and 4 extending from left and right to the center, and are configured to be overlapped at the center part. It is relatively thin so as to be elastically deformable, and can pass through the cable 5 when pressed down.

The lower portion of the cable holder 1 is formed by inserting one leg 6 extending downward from the center of the upper frame into the through hole 9 of the printed board 8 so as to face upward from the tip of the leg 6 not shown. The anchor-shaped locking piece is expanded by elasticity, and this locking piece engages with the back surface of the printed board 8,
The retaining and the standing posture are maintained.

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 By inserting the cable 5 into 2,
The cable 5 is positioned and held so as to be removable.

However, although the cable holder 1 can simply insert and hold the cable 5, it is not possible to hold, for example, a component attached to the cable 5 so as to be able to be inserted and removed, as is clear from the drawing.

FIG. 16 is a perspective view showing a holder 11 capable of holding components. A relatively thin metal plate is punched and bent by press forming, and the upper holding portion 12 is formed.
Is an upright surface 14 on which both sides of the substrate 13 are parallel in the upward direction, and the middle of each upright surface 14 is separated by a notch 15.

[0010] As a leg 16 which is bent downward on both sides of the substrate 13 and parallel to each other, a narrow insertion piece 17 at the tip thereof is inserted into the through hole 9 of the printed board 8, and a stepped portion of the leg 16 is formed. The end face is in an upright posture in contact with the surface of the printed board 8, and the insertion piece 17 is soldered to a copper foil pattern (not shown) on the back face of the printed board 8 and fixed in position.

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.
The optical component 23 having the function of optically multiplexing or demultiplexing an optical signal, which is optically coupled inside, is inserted and arranged in the holding portion 12 of the holder 11 as shown in the figure.

In this case, the holders 11 are erected at two places with an interval therebetween, and are fitted into both holding portions 12.
A binding wire band (trade name: tie wrap) 24 made of synthetic resin is wound around the upper side of the optical component 23 from the lower surface of the substrate 13 so as to pass through the cutout 15 and tighten. Thus, the optical component 23 is fixedly held.

[0013]

The cable holder 1 shown in FIG. 15 is a conventional holder as shown in FIG. 15. Since a through hole 9 must be formed in the printed board 8, especially in the case of a multilayer printed board, There is a restriction in providing a through hole, and it cannot be provided at an arbitrary position.

Since the cable 5 is inserted into and held in the holding portion 2, the cable 5 cannot be held in a tightened state.
Cannot be held in a similar state so that it can be inserted and removed.

In the holder 11 shown in FIG. 16 as well, the through holes 9 must be provided in the printed board 8 and means for soldering and fixing on the back side are also required. In order to hold the optical component 23, a bundled band 24 and a tool for fastening the bundled band are required. Cutting, removing and reattaching requires a new bundle band 24 and its attaching work.

In view of the above-mentioned conventional problems, the present invention is compact and can be directly attached to the surface of a printed circuit board, and can be handled without being limited to wiring materials or parts. An object of the present invention is to provide a versatile holder having good operability.

[0017]

Means for Solving the Problems The first means of the present invention for solving the above-mentioned problems is that the mounting surface to the printed board and both sides of the mounting surface are parallel to each other. And an opening formed by folding the upright end of the upstanding surface toward the mounting surface and an opposing holding portion.

According to the first means, the mounting surface can be directly mounted on the surface of the printed board, and the holding portion is folded back on the inner surface side of the upright surface, so that the mounting height can be kept extremely low.

Since the length from the mounting surface to the holding portion passes through the upright surface, the folded portion, and the opening, its flexibility and elasticity are utilized as much as possible, and the size of the member to be held. Can be greatly expanded and can be held flexibly.

The second means, which is the gist of the means of the present invention, comprises a mounting surface to a printed board, an upright portion formed so that both sides of the mounting surface are parallel to each other, and a tip of the upright portion. This is a holder in which an elastic band-shaped thin plate is formed on an opening formed by folding the side toward the mounting surface side and an opposite holding portion, and an elastic material is applied to the holding portion.

According to this second means, the mounting surface can be directly mounted on the printed board surface, and the holding portion is folded back on the inner surface side of the upright surface, so that the mounting height can be kept extremely low.

Since the length from the mounting surface to the holding portion passes through the upright surface, the folded portion, and the opening, its flexibility and elasticity are utilized as much as possible. Can be greatly expanded and can be held flexibly.

The elastic member provided to the holding portion prevents the held components and wiring members from moving, and has a cushioning effect against an impact due to its soft elasticity.
The third means, which is the gist of the means of the present invention, is:
A mounting surface to the printed board, an upright surface formed so that both sides of the mounting surface are parallel to each other, and an opening and an opposing holding portion configured by folding the upright end to the mounting surface side, An elastic band-shaped thin plate is formed on the opening, and a first elastic material having a convex shape is provided on the opening side of the holding portion, and a second elastic material having a convex shape is provided on the distal end portion. The convex shape of the material is a holder smaller than the convex shape of the second elastic material.

According to the third means, the mounting surface can be directly mounted on the surface of the printed board, and since the holding portion is provided by folding back on the inner surface side of the upright surface, the mounting height can be kept extremely low.

Since the length from the mounting surface to the holding portion passes through the upright surface, the folded portion, and the opening, its flexibility and elasticity are utilized as much as possible and the size of the member to be held. Can be greatly expanded and can be held flexibly.

Since the convex shape of the first elastic material is small,
It is easy to insert the component or the wiring material into the holding portion, and the inserted component or the wiring material is prevented from coming off. Since the convex shape of the second elastic material is large, components and wiring materials to be inserted into the holding portion are stably supported without passing through the holding portion, and the flexibility and elasticity provide a cushioning effect against an impact or the like. Play.

According to a fourth aspect of the present invention, a flat surface parallel to the mounting surface is formed at a folded portion between the upright surface and the opening. Alternatively, the present invention can be applied to any of the holders of the third means.

According to the fourth means, since the flat surface is parallel to the mounting surface, the flat surface is moved by being sucked to the vacuum suction head at the tip of the robot hand and moved to a predetermined position on the printed board. By opening it, it can be arranged on the surface of the printed board, so that automated mounting is possible. Of course, after the arrangement, it can be fixed by soldering to the arrangement surface with solder supplied in advance.

According to a fifth aspect of the present invention, in the fifth aspect, the mounting surface is provided with a projection which comes into contact with the printed board surface or a cutout which reduces a contact area with the printed board. The present invention can be applied to the holder of any one of the first to fourth means.

According to the fifth means, when soldering and mounting on a printed board, the required heat amount can be reduced because the projecting portion to be soldered protrudes from the mounting surface. Mounting becomes possible in the soldering time.

Alternatively, by providing the notch, the amount of heat required for soldering can be reduced, so that the mounting can be similarly performed in a short soldering time.

The leading ends of the upright surfaces 34 are the two upright surfaces 34, 3
4 is folded back to the mounting surface 32 side so as to be inside, and the folded portion 35 is formed on a flat surface 36 parallel to the mounting surface 32. By being folded in this way, an opening 37 and a facing holding portion 38 are formed.

As shown in the drawing, the holding portion 38 is
A curved portion 39 is formed to approach the fourth side, and both ends 41 are approached again by the inclined surface 42 and terminated. Because of this, the space between the curved portions 39 is farther than the space between the openings 37, and the space between the two distal ends 41 is set to the closest state.

The hatched portion shown in FIG. 1A is a portion 43 which has been subjected to solder plating. 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.

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 by copper foil. As shown by a two-dot chain line on the holder mounting pattern 46,
The mounting surface 32 of the holder 31 is placed.

This can be done simultaneously with the mounting and mounting of electric circuit components (not shown), or it can be individually soldered with a soldering iron or the like.

The long side of the holder mounting mounting pattern 46 is
As is apparent from the figure, since the protrusions extend appropriately longer than the width of the mounting surface 32 and intersect, the solder (not shown) covers the mounting surface 32 so that a secure fixing state can be obtained.

Referring to FIGS. 2 and 3A, an optical component 52 through which an optical fiber 51 penetrates, for example,
It is an optical connection part in which both ends of a pair of optical fiber cores are abutted and fused and connected, so-called spliced connection part is covered and protected and mechanically reinforced and protected. The state where the covering part as the optical component 52 is inserted into the holding part 38 of the holder 31 with the opening 37 expanded is shown.

As shown in the figure, the holding portion 38 is
A curved portion 39 is formed to approach the fourth side, and both ends 41 are approached again by the inclined surface 42 and terminated. Because of this, the space between the curved portions 39 is farther than the space between the openings 37, and the space between the two distal ends 41 is set to the closest state.

The above configuration is similar to the holder 31 shown in FIG.
The printed board 45 is provided on the mounting surface 32 side.
Similarly, a solder plated portion 43 for soldering and fixing to the holder mounting / mounting pattern 46 is provided.

As shown, a first elastic member 62 having a convex shape on the side of the opening 37 of the holding portion 38 is provided on the holder 61.
