[Industrial application fields]
The present invention relates to a push button switch coupling body in which a plurality of push button switches are attached to a transport tape.
[0002]
[Prior art]
The push button switch coupling body is made to mount the push button switch on the substrate using an automatic mounting machine or an automatic insertion machine, and the conventional push button switch coupling body is configured as shown in FIG. ing. In FIG. 4, 101 is a transport tape, and 103 is a push button switch attached to the transport tape. A typical transport tape 101 is composed of a combination of an elongated paper base 101a called a capacitor base and an adhesive paper 101b attached to the surface of one end in the width direction of the base 101a. The front end portions of the two supporting leg portions 105 and 105 of the push button switch 103 are sandwiched between the mount 101a and the adhesive paper 101b. A plurality of push button switches 103 are attached to the transport tape 101 continuously at a predetermined interval in the longitudinal direction. The push button switch 103 is a case main body made of an insulating resin having a contact housing recess in which two terminals 107 and two kinds of contacts electrically connected to these terminals are insert-molded and open toward the front surface. 109. The contact storage recess of the case body 109 generally stores a plate-shaped spring contact. When the dish-shaped spring contact is pushed and deformed by the operation member 111 made of insulating resin, the two kinds of contacts are short-circuited. When the operator releases the operation member 111 from the finger, the dish-shaped spring contact is reversed by the spring force to return to the original state, and simultaneously returns the operation member 111 to the original position. A metal attachment frame 113 is attached to the case main body 109. The mounting frame 113 is located on the front surface side of the case body 109 and has a front wall portion 113a in which a through-hole through which the operation member 111 passes is formed, and both side surfaces of the case body 109 from both ends of the front wall portion 113a. And a pair of attachment terminals 113c and 113c provided integrally at the lower end of the pair of side walls 113b and 113b. The set of mounting terminals 113c and 113c can also be used as ground terminals. In this push button switch, the extended portions of the two terminals 107 and 107 constitute two support legs 105 and 105. In other words, part of the two terminals 107 and 107 also serves as part of the support legs 105 and 105.
[0003]
When the push button switch is removed from the push button switch coupling body and automatically inserted into the mounting hole formed in the substrate, the pair of clamp members 115 and 115 as shown by the broken lines extending from the automatic insertion machine are provided as the push button switch. The front end surface 111 a of the operation member 111 of 103 and the rear end surface 109 a of the case main body 109 are clamped. In a state where the push button switch 103 is clamped by the clamp members 115, 115, the support legs 105, 105 are positioned between the front end surface 111 a of the operation member 111 and the rear end surface 109 a of the case body 109, that is, The positional relationship between the support legs 105 and 105 with respect to the case body 109 is determined so that the illustrated dimension L1 is substantially equal to the dimension L2. This simplifies the positional relationship between the two (115 and 103) when the push button switch 103 attached to the transport tape 101 is clamped by the clamp members 115 and 115, and facilitates adjustment before the automatic insertion machine is operated. Or to make it unnecessary. In addition, this positional relationship makes it easy or unnecessary to set the automatic cutting machine, which is used in addition to the automatic insertion machine, for cutting the supporting legs 105 and 105 halfway.
[0004]
[Problems to be solved by the invention]
When the extended portions of the terminals 107 and 107 are the supporting leg portions 105 and 105 as in the prior art, the following problems occur.
[0005]
(1) Since an excessive force is applied to the terminal 107 when the support leg 105 is cut or transported, it is necessary to increase the mechanical strength of the terminal more than necessary.
[0006]
(2) If the terminal 107 is deformed at the time of transportation or when the supporting leg 105 is cut, the deformation of the terminal causes a soldering failure when the terminal is soldered to the electrode of the substrate.
[0007]
(3) The mount used for the transport tape 101 is infiltrated with various chemicals or additives for the purpose of increasing the strength of the mount. Some of these additives contain a component that corrodes metal plating such as silver plating applied to the surface of the terminal, such as sulfur. If such a component is included in the mount, it reaches the surface of the terminal 107 from the mount through the surface of the support leg 105, corrodes the metal plating on the surface of the terminal 107, and Deteriorate the solderability of the surface.
[0008]
(4) When the support leg 105 is disposed at the center of the front dimension L1 and the rear dimension L2 of the support leg 105 of the push button switch 103, the extension dimension of the terminal 107 is the support leg. In order to create a rear dimension L2 substantially equal to L1, the longitudinal dimension of the case body 109 needs to be increased more than necessary. For this reason, the shape of the push button switch increases. The portion of the case main body 109 located behind the terminal 107 is not necessary for the function of the push button switch, but a large amount of resin is required to form this portion. Further, when the shape of the push button switch is increased, the size of the box for storing the coupling body is increased.
[0009]
An object of the present invention is to provide a push button switch coupling body in which an excessive force is not applied to a terminal.
[0010]
Another object of the present invention is to provide a push button switch coupling body in which a terminal is not easily deformed.
[0011]
Still another object of the present invention is to provide a push button switch coupling body in which the surface of the terminal is less likely to corrode.
[0012]
Another object of the present invention is to provide a push button switch connector that can reduce the maximum thickness dimension.
[0013]
[Means for Solving the Problems]
In the present invention, the end of at least one supporting leg extending from the push button switch is fixed to the transport tape, and the push button switch is attached to the front surface of the case body made of insulating resin. A push button switch connector having the above structure is an object of improvement. The structure of the push button switch is not particularly limited, but a general push button switch is an insulating resin having a contact housing recess in which a plurality of terminals and a plurality of contacts are insert-molded and opened toward the front surface. A case body made of spring, a spring contact housed in a contact housing recess of the case body, an operating member for operating the spring contact, and a metal mounting frame attached to the case body. The structure of the spring contact is arbitrary, but a structure in which the contacts are short-circuited by themselves when deformed by the operation member is preferable. When the operation by the operation member is released, the spring contact returns to the original state due to its spring property. As such a spring contact, a plate-shaped spring contact is generally used. The mounting frame is preferably provided with a front wall portion located on the front side of the case body and a pair of side wall portions extending from both ends of the front wall portion along both side surfaces of the case body. Further, the structure and the material of the transport tape are arbitrary as long as the end of the support leg of the push button switch can be held to some extent firmly.
[0014]
In the present invention, the support leg is attached to the attachment frame. Although the mounting manner of the supporting leg is arbitrary, it is preferable that the supporting leg is provided integrally with the mounting frame. That is, if the supporting leg and the mounting frame are integrally formed, the supporting leg can be attached to the mounting frame at a low cost. However, as a matter of course, the supporting legs may be attached to the attachment frame by welding as necessary.
[0015]
The attachment position for attaching the support leg to the attachment frame is arbitrary, but if the attachment frame has a structure including the front wall part and a pair of side wall parts, the support leg part is attached. What is necessary is just to attach to the front wall part or one set of side wall part of a flame | frame. In particular, in the case of a push button switch in which the distance from the virtual plane on which the support leg is located to the front end surface of the operation member and the distance from the virtual plane to the rear end surface of the case body are substantially equal, the support leg is It is preferable to attach to the front wall part of an attachment frame. In this way, the thickness dimension (the dimension in the front-rear direction) of the push button switch can be made significantly smaller than before.
[0016]
When the supporting leg is attached to the mounting frame as in the present invention, the terminal is not used as a part of the supporting leg, and therefore, the chance of applying an excessive force to the terminal before automatic insertion is reduced. Therefore, it is not necessary to increase the mechanical strength of the terminal more than necessary, and it is possible to suppress the occurrence of poor soldering due to the deformation of the terminal.
[0017]
In the present invention, since the terminal is not used as a part of the support leg, even if the carrier tape is impregnated with a component that corrodes the metal surface, even if the surface of the support leg is corroded, The surface of the terminal is not substantially corroded, and it is possible to prevent the occurrence of poor soldering due to the corrosion of the terminal surface.
[0018]
Further, when the support leg is attached to the front wall of the mounting frame, the virtual plane on which the front wall is located becomes the virtual plane on which the support leg is located, and from this virtual plane to the front end surface of the operation member. And the distance from the virtual plane to the rear end surface of the case main body can be significantly reduced as compared with the conventional case. As a result, it is no longer necessary to unnecessarily increase the shape of the rear part of the case body as in the conventional case, and the thickness of the push button switch (the dimension in the front-rear direction) can be significantly reduced compared to the conventional case. The amount of resin required to form the main body can be reduced.
[0019]
【Example】
Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an enlarged view of a main part of an embodiment of the push button switch connector of the present invention. 2A to 2D respectively show an enlarged front view, an enlarged right side view, an enlarged bottom view, and an enlarged rear view of the push button switch shown in FIG. In these drawings, 1 is a transport tape, and 3 is a push button switch attached to the transport tape 1. The transport tape 1 of the present embodiment is configured by combining a paper-like long board 1a such as cardboard and an adhesive paper 1b attached to the surface of one end in the width direction of the board 1a. As the mount 1a and the adhesive paper 1b that can be used in this embodiment, those sold by Utsunomiya Paper Co., Ltd. under the name DC-18028 (product number) are used. The mount 1a has a thickness dimension of about 0.4 mm and a width dimension of about 18 mm, and is stiff to the extent that the shape is not easily deformed (has self-supporting properties). A plurality of holes 1c are formed in the mount 1a at intervals of about 13 mm in the longitudinal direction. The mount 1a is impregnated with an additive to increase the strength. However, components such as sulfur contained in this type of additive corrode the surface of the mounting frame, which will be described in detail later. The adhesive paper 1b is a thin paper having a thickness dimension of about 0.15 mm and a width dimension of about 6 mm, and is adhered to the mount 1a using an acrylic adhesive. The tip portions of the two support legs 5a and 5b of the push button switch 3 are sandwiched between the mount 1a and the adhesive paper 1b, respectively. On the surface of one end in the width direction of the mount 1a of the transport tape 1, support leg portions 5a and 5b of the plurality of push button switches 3 and 3 are placed with an interval of about 5 mm in the longitudinal direction. The adhesive paper 1b is bonded from above.
[0020]
As shown in FIG. 2, the push button switch 3 is formed by insert molding two terminals 7a and 7b and two kinds of contacts (not shown) electrically connected to the terminals 7a and 7b. An opening is provided, and the opening side of this opening is the front A case main body 9 made of insulating resin having a contact housing recess (not shown) is provided. As is well known, this type of push button switch is mass produced. Specifically, a plurality of case bodies are prepared so that a hoop-like frame integrally including a plurality of switch terminals and a plurality of contacts connected to these terminals is prepared, and the contact portions of the frames are included therein. 9 is formed by a mold. As a result, part of the terminals and contacts are insert-molded into the case body 9. After the insert molding is completed, the hoop-shaped frame is cut for each individual switch. Two projecting portions 7c and 7d projecting from the upper end of the case body 9 are the remaining portions of the cut hoop-like frame.
[0021]
In a contact storage recess (not shown) formed in the case main body 9, a dish-shaped spring contact is generally stored. When the dish-shaped spring contact is pushed and deformed by the operation member 11 made of insulating resin, the two kinds of contacts are short-circuited. When the operator releases the operation member 11 from the finger, the dish-shaped spring contact is reversed by the spring force to return to the original state, and simultaneously returns the operation member 11 to the original position. The structure of the contact and the plate-shaped spring contact is described in detail in Japanese Utility Model Publication No. 3-38744.
[0022]
A metal attachment frame 13 is attached to the case body 9. The mounting frame 13 is formed by pressing and bending a thin iron plate having a surface plated with solder. The mounting frame 13 is located on the front surface side of the case body 9 and has a front wall portion 13a in which a through hole 15 through which the operation member 11 passes is formed, and both side surfaces of the case body 9 from both ends of the front wall portion 13a. And a pair of side wall portions 13b and 13c extending in the direction. Further, the mounting frame 13 of the present embodiment integrally has the above-mentioned supporting leg portions 5a and 5b. Four small through holes (not shown) are formed at the four corners of the front wall portion 13a. In these four small through-holes, four frame mounting projections provided integrally with the case main body 9 are fitted at the four corners of the front end face of the case main body 9 described above. The tip portions of the four protrusions are respectively melted and deformed by heating or ultrasonic vibration to constitute retaining portions 10a to 10d larger than the diameters of the four through holes formed in the mounting frame 13. Basically, the mounting frame 13 is fixed to the case body 9 by these retaining portions 10a to 10d.
[0023]
The front wall portion 13a of the mounting frame 13 has three extension portions 13a1 to 13a3 extending beyond the lower end surface 9a of the case body 9 in the direction in which the support legs 5a and 5b extend. These three extension portions 13a1 to 13a3 constitute an extension portion of the front wall portion 13a, and of these extension portions, the extension portions 13a1 and 13a2 constitute the attachment portions of the supporting legs 5a and 5b. The extension 13a3 constitutes a tilt-preventing protruding piece that prevents the case body 9 from tilting forward. The extension portion 13a3 is composed of an inclined portion 13a31 extending forward while facing downward from the front wall portion 13a, and a tip portion 13a32 extending substantially directly below the tip of the inclined portion. The end surface of the tip portion 13a32 constitutes a contact portion that comes into contact with the surface of the circuit board (attached portion) on which the switch is mounted.
[0024]
As shown in FIGS. 2 (B) to 2 (D), each of the pair of side wall portions 13b and 13c of the mounting frame 13 is cut and raised toward the inner side (toward the case main body 9 side). Cut and raised pieces 13b1 and 13c1 are formed. These cut-and-raised pieces 13b1 and 13c1 are free ends whose ends close to the front wall portion 13a are movable, and fixed ends to which the end portions away from the front wall portion 13a are fixed. As shown in FIGS. 2 (C) and 2 (D), groove portions 9b1 and 9c1 are formed on the side wall portions 9b and 9c of the case body 9 corresponding to the cut and raised pieces 13b1 and 13c1, respectively. These groove portions 9b1 and 9c1 extend from the rear of the case main body 9 toward the front, stop in the middle, and open toward both the rear and side directions of the case main body 9. When the mounting frame 13 is fitted to the case body 9 from the front side of the case body 9 toward the rear side, the free ends of the cut and raised pieces 13b1 and 13c1 enter the groove portions 9b1 and 9c1. When the free ends of the cut-and-raised pieces 13b1 and 13c1 enter the grooves 9b1 and 9c1, the free ends of the cut-and-raised pieces 13b1 and 13c1 become the grooves 9b1 and 9c1 even if the mounting frame 13 is pulled forward, upward and downward. The mounting frame 13 is prevented from moving by hitting the inner wall surface of 9c1.
[0025]
Extension portions 13b2 and 13c2 that extend beyond the end surface 9a of the case body 9 in the direction in which the two support legs 5a and 5b extend are also integrally provided on the side wall portions 13b and 13c of the mounting frame 13. These extensions 13b2 and 13c2 are in contact with the surface of the circuit board (attached part) on which the switch is mounted. The extension portion 13a3 and the extension portions 13b2 and 13c2 provided on the mounting frame 13 constitute spacer means or support means for supporting the case body 9 in a state of floating on the surface of the circuit board (attached portion). . In the lower regions of the side wall portions 13b and 13c of the mounting frame 13, relatively large cutout portions 17 cut from the front wall portion 13a side toward the extension portions 13b2 and 13c2 are formed.
[0026]
In the present embodiment, the extension portions 13a1 and 13a2 are partially provided on the front wall portion 13a of the mounting frame 13, and the notch portions 17 are formed on the pair of side wall portions 13b and 13c, respectively. When the flux used during soldering rises along the supporting legs 5a and 5b inserted into the provided mounting holes, the case main body passes through the through holes 15 provided in the front wall 13a. This is to prevent flux from entering inside 9. That is, by providing the extension portions 13a1 and 13a2 partially on the front wall portion 13a of the mounting frame 13, the creeping distance of the flux rise in the front wall portion 13a from the support legs 5a, 5b to the through hole 15 is increased. is doing. Further, by providing the notch portion 17, the creeping distance of the flux rising through the side wall portions 13b and 13c and the front wall portion 13a from the supporting leg portions 5a and 5b to the through hole 15 is increased. In this embodiment, the extension portions 13a1 and 13a2 and the notch portion 17 constitute a creeping distance increasing structure portion.
[0027]
As shown in FIG. 2D, on the rear end surface of the case body 9, two rectangular protruding portions 9d and 9e are formed, and five concave portions 9f1 to 9f5 are formed. These recesses are provided for molding reasons when the case body 9 is molded by a mold.
[0028]
As shown in FIG. 2B, in the push button switch of the present embodiment, when the front end surface 11a of the operation member 11 and the rear end surface of the case body 9 are clamped by a clamp member of an automatic insertion machine (not shown), The operation member 11 deforms a spring contact (not shown) to reach the rear, and is at the position of the broken line shown in the figure. In this embodiment, in this state, the distance L1 from the virtual plane where the two support legs 5a and 5b are located to the front end surface 11a of the operating member 11 and the distance from the virtual plane to the rear end surface of the case body 9 L2 is almost equal. Thus, during automatic insertion, adjustment of the automatic insertion machine and support leg portions 5a and 5b are moved to the parting line [virtual line P. of FIG. L. ] It is easy or unnecessary to adjust the cutting machine for cutting along the line. Further, according to this embodiment, the distance L1 from the terminal virtual plane where the supporting legs 5a and 5b are located to the front end surface 11a of the operation member 11 and the distance L2 from the virtual plane to the rear end surface of the case body 9 are conventionally set. Compared to the previous model, there is no need to unnecessarily increase the shape of the rear part of the case body, and the push button switch thickness (longitudinal dimension) is significantly larger than before. Can be made smaller. Note that the present invention is not limited to the case of using a push button switch of a type in which the dimensions L1 and L2 are substantially equal as in the present embodiment.
[0029]
Further, as shown in FIG. 2A, in this embodiment, the width dimension W1 (specifically about 4 mm) between the two terminals 7a and 7b is between the two supporting legs 5a and 5b. Is smaller than the width dimension W2 (specifically, about 5 mm), and the centers of the two terminals 7a and 7b and the centers of the two support legs 5a and 5b substantially coincide with each other. With such a configuration, there is an effect that no excessive force is applied to the terminals 7a and 7b.
[0030]
When the push button switch connector of this embodiment is loaded into an automatic insertion machine and the push button switch 3 is mounted on the circuit board, the parting line P.A. of FIG. L. Since the supporting leg portions 5a and 5b are cut along the line 4, the terminals 7a and 7b and the remaining portions of the cut supporting leg portions 5a and 5b are inserted into the circuit board 4 with respect to one switch. Two mounting holes (through holes) are formed. The terminals 7a and 7b inserted into these four mounting holes and the remaining portions of the cut support legs 5a and 5b are soldered to soldering electrodes provided on the back surface of the circuit board. If the remaining portions of the supporting legs 5a and 5b are also fixed to the circuit board by soldering, the front end of the push button switch 3 can be prevented from lifting.
[0031]
When the push button switch coupling body of this embodiment is housed in the housing case 19 to form a push button switch coupling body pack, the transport tape 1 is folded and folded at a predetermined pitch as shown in FIG. Store in the case 19. According to the present embodiment, the maximum thickness dimension (L1 + L2) of the push button switch 3 is significantly smaller than that of the prior art. Therefore, it becomes possible to store more push button switches than ever in a storage case of the same size.
[0032]
In the above embodiment, the support legs 5a and 5b are formed integrally with the mounting frame 13. However, the support legs 5a and 5b are formed separately from the mounting frame 13, and the support legs are formed by spot welding or the like. Of course, the parts 5a and 5b may be fixed to the mounting frame 13.
[0033]
In the above embodiment, the supporting legs are provided on the front wall portion of the mounting frame, but it is needless to say that the supporting legs may be provided on a pair of side wall portions. 3A and 3B are an enlarged front view and an enlarged right side view of the main part of the push button switch used in the embodiment in which the supporting leg portions 25a and 25b are provided on the pair of side wall portions 23b and 23c. is there. In these drawings, what is different from the push button switch 3 shown in FIG. 2 is the shape of the mounting frame 23 and the positions and shapes of the supporting legs 25a and 25b. Since the other points are the same as in the example of FIG. 2, the same components as those in the example shown in FIG. 2 are denoted by the same reference numerals as those in FIG. In this embodiment, the supporting leg portions 25a and 25b are integrally provided on the pair of side wall portions 23b and 23c. The extension portions 23b2 and 23c2 of the pair of side wall portions 23b and 23c are divided into two by a cut 20. The extension portions 23b3 and 23c3 on the front wall portion 23a side are bent inward by about 45 degrees, and the tip portions constitute attachment portions of the support legs 25a and 25b. On the upper side of the extension portions 23b3 and 23c3, recesses 21 are formed that open toward the front and the sides. The front wall portion 23 a and the side wall portions 23 b and 23 c are not connected from the lower end portion to the vicinity of the upper end portion of the concave portion 21. The bending structure of the extended portions 23b3 and 23c3 and the recess 21 constitute a creeping distance increasing structure portion for increasing the creeping distance of the flux rising from the supporting legs 25a and 25b. In particular, since the extension portions 23b3 and 23c3 are inclined, the flux is difficult to rise upward, and the concave portion 21 is a pool portion of the flux that has risen. In the drawing, the front wall portion 23a and the extended portions 23b3 and 23c3 are drawn so as to be in contact with each other, but in reality, a slight gap is formed between them. This gap prevents the flux from being transmitted to the front wall portion 23a from the middle of the extended portions 23b3 and 23c3. Also in this embodiment, the dimension L1 is substantially equal to the dimension L2, and the dimension W2 is larger than the dimension W1.

【The invention's effect】
According to the present invention, since the supporting leg is attached to the mounting frame, the terminal is not used as a part of the supporting leg, and an opportunity to apply an excessive force to the terminal before automatic insertion is reduced. Therefore, there is no need to increase the mechanical strength of the terminal more than necessary, and there is an advantage that the occurrence of soldering failure due to the deformation of the terminal can be suppressed. Further, according to the present invention, since the terminal is not used as a part of the supporting leg, the carrier tape is impregnated with a component that corrodes the metal surface, and the surface of the supporting leg is corroded. However, since the surface of the terminal is not substantially corroded, there is an advantage that it is possible to prevent the occurrence of defective soldering due to the corrosion of the terminal surface.

In particular, when the support leg is attached to the front wall of the mounting frame, the virtual plane on which the front wall is located becomes the virtual plane on which the support leg is located, and from this virtual plane to the front end surface of the operation member. The distance from the imaginary plane to the rear end surface of the case body can be significantly reduced compared to the conventional case, so there is no need to unnecessarily increase the shape of the rear part of the case body as in the past In addition, the thickness of the push button switch can be greatly reduced as compared with the conventional case, and there is an advantage that the amount of resin necessary for forming the case body can be reduced.
