Description

The present disclosure relates to surface mount clamps.

A surface-mount clamp that can be surface-mounted on a component mounting surface has been proposed (see, for example, Patent Document 1). The replacement parts clip (corresponding to the surface-mounted clamp in the present disclosure) described in Patent Document 1 is a holding device composed of a bottom part soldered to the component mounting surface and a pair of metal pieces extending from the bottom part. It is equipped with a section. When the component mounting surface faces upward, the replacement part (corresponding to the object to be held in the present disclosure) is moved from above to below the holding part to introduce the replacement part into the holding part. I can do it.

JP 2017-126459 Publication

However, depending on the location where the electronic circuit board is placed, for example, it may not be possible to secure a sufficient working space above the holding part (that is, in the direction in which the component mounting surface faces). In this case, it is difficult to place the replacement part above the replacement part clip, resulting in poor workability.

Further, for example, depending on the location where the electronic circuit board is disposed, a work space may be secured in the lateral direction of the holding portion (that is, the direction along the component mounting surface). However, with the replacement part clip described above, the replacement part cannot be introduced into the holding part from the lateral direction of the holding part.

Furthermore, for example, if a work space can be secured above the holding part, or if a work space can be secured in the lateral direction of the holding part, clips for replacement parts with different shapes suitable for each case can be prepared. I can. However, in this case, the versatility of each of these differently shaped replacement part clips is reduced.

In one aspect of the present disclosure, it is desirable to provide a surface-mounted clamp that has a higher degree of freedom in introducing an object to be held into a holding part than conventional products.

A surface mount type clamp in one aspect of the present disclosure is a surface mount type clamp configured to be surface mounted on a component mounting surface and capable of holding a linear or columnar object to be held at the mounting location. This surface mount type clamp includes a first bonding surface, a first suction surface, a second bonding surface, a second suction surface, and a holding portion. The first joint surface, the first suction surface, the second joint surface, the second suction surface, and the holding part are integrally formed of a single metal plate. The first bonding surface and the second bonding surface are each configured to be able to be soldered to the component mounting surface, and when the surface mount type clamp is surface mounted to the component mounting surface, the first bonding surface and the second bonding surface One of them is soldered to the component mounting surface. The first suction surface and the second suction surface are each configured to be suctionable with a suction nozzle of an automatic mounting machine, with the first suction surface facing in the opposite direction to the first bonding surface, and the second suction surface facing the second suction surface. It is oriented in the opposite direction to the joint surface. The holding part has an opening through which the object to be held can be introduced inside, and when the object to be held is introduced from the opening into the inside, the outer periphery of the object to be held is surrounded by an area other than the opening. is configured to be able to hold an object to be held. The direction in which the opening is directed is defined as the opening direction, and the opening direction is different when the first bonding surface is soldered to the component mounting surface and when the second bonding surface is soldered to the component mounting surface. It is configured to be.

According to the surface mount type clamp configured in this way, the holding part is different when the first bonding surface is soldered to the component mounting surface and when the second bonding surface is soldered to the component mounting surface. The opening directions are different. Therefore, for example, when carrying out the work of introducing the object to be held into the holding part, a bonding surface with a more convenient opening direction is selected from among the first bonding surface and the second bonding surface, and the surface-mounted clamp can be surface mounted on the component mounting surface. Thereby, it is possible to improve the work efficiency when carrying out the work of introducing the object to be held into the holding part.

Further, the surface mount clamp of the present disclosure has higher versatility than the case where surface mount clamps of different shapes corresponding to the different opening directions described above are prepared. Therefore, instead of using two products with different shapes, it is possible to use one product with a single shape, and the mass production effect can reduce the manufacturing cost of the product.

[Surface mount type clamp configuration]
The surface mount type clamp 1 shown in FIGS. 1A, 1B, 1C, and 1D includes a first joint surface 3A, a first suction surface 5A, a second joint surface 3B, a second suction surface 5B, and a holding part 7. The first joint surface 3A, the first suction surface 5A, the second joint surface 3B, the second suction surface 5B, and the holding part 7 are made of a single metal plate (in this embodiment, a thin plate of phosphor bronze for spring use, 0.15±0.03mm). As illustrated in FIGS. 2A and 2B, the surface-mounted clamp 1 is surface-mounted on a component mounting surface 53 of an electronic circuit board 51, and is capable of holding a linear or columnar object 55 at the mounting location. It is configured.

The first bonding surface 3A and the second bonding surface 3B are each configured to be solderable to the component mounting surface 53. The first suction surface 5A and the second suction surface 5B are each configured to be suctionable with a suction nozzle of an automatic mounting machine. The first suction surface 5A is oriented in the opposite direction to the first bonding surface 3A. The second suction surface 5B is oriented in the opposite direction to the second bonding surface 3B. When the surface mount type clamp 1 is surface mounted on the component mounting surface 53, one of the first bonding surface 3A and the second bonding surface 3B is soldered to the component mounting surface 53.

More specifically, the surface-mounted clamp 1 can be used in a first orientation, as shown in FIGS. 1A and 1B. When the surface mount type clamp 1 is oriented in the first direction, the first bonding surface 3A is oriented downward and the first suction surface 5A is oriented upward. Therefore, the first suction surface 5A is suctioned by the suction nozzle of the automatic mounting machine, and the surface mount type clamp 1 is placed on the component mounting surface 53 of the electronic circuit board 51 placed horizontally, as shown in FIG. 2A. Then, the first bonding surface 3A can be soldered to the component mounting surface 53.

In this embodiment, when the surface mount type clamp 1 is in the first orientation, the horizontal dimension is approximately 2.5 mm, the longitudinal dimension is approximately 1.8 mm, and the vertical dimension is approximately 1.65 mm. The vertical dimension between the first joint surface 3A and the first suction surface 5A is approximately 1.65 mm. When the surface mount type clamp 1 is oriented in the first direction, the second bonding surface 3B is oriented diagonally to the lower left, and the second suction surface 5B is oriented diagonally to the upper right.

Moreover, the surface mount type clamp 1 can be used in a second orientation, as shown in FIGS. 1C and 1D. When the surface mount type clamp 1 is oriented in the second direction, the second bonding surface 3B is oriented downward and the second suction surface 5B is oriented upward. Therefore, the second suction surface 5B is suctioned by the suction nozzle of the automatic mounting machine, and the surface mount type clamp 1 is placed on the component mounting surface 53 of the electronic circuit board 51 placed horizontally, as shown in FIG. 2B. Then, the second bonding surface 3B can be soldered to the component mounting surface 53.

In this embodiment, when the surface mount type clamp 1 is in the second orientation, the horizontal dimension is approximately 1.77 mm, the longitudinal dimension is approximately 1.8 mm, and the vertical dimension is approximately 2.51 mm. The vertical dimension between the second joint surface 3B and the second suction surface 5B is approximately 1.79 mm. When the surface mount type clamp 1 is in the second orientation, the first bonding surface 3A is directed diagonally downward to the right, and the first suction surface 5A is directed diagonally upward to the right.

As shown in FIGS. 2A and 2B, the holding portion 7 has an opening 9 into which a linear or columnar object 55 to be held can be introduced. When the object to be held 55 is introduced into the inside of the holding part 7 from the opening part 9, the holding part 7 can hold the object to be held 55 by surrounding the outer periphery of the object to be held 55 in a range other than the opening part 9. It is composed of Regardless of whether the surface mount type clamp 1 is oriented in the first direction or the second direction, the holding portion 7 can hold the linear or columnar holding object 55 extending in the front-rear direction. In the case of this embodiment, the object to be held 55 is a cable with a diameter of 1.15±0.05 mm. However, as long as the object 55 to be held has a similar shape, it is also possible to hold a linear object or a columnar object other than the cable.

In the case of this embodiment, the surface mount type clamp 1 includes a first horizontal part 11A, a first inclined part 13A, a second inclined part 13B, as shown in FIGS. 3A, 3B, 3C, 3D and 3E. It includes a third inclined part 13C and a second horizontal part 11B. Note that the rear view of the surface-mounted clamp 1 appears symmetrical to the front view shown in FIG. 3C.

The first horizontal portion 11A is a portion that extends in the left-right direction when the surface-mounted clamp 1 is in the first orientation. One surface of the metal plate constituting the first horizontal portion 11A is directed downward and serves as a first joint surface 3A. The first inclined portion 13A is a portion connected to the left end of the first horizontal portion 11A via the first bent portion 15A, and extends diagonally upward and to the right from the first bent portion 15A. The second inclined portion 13B is a portion that is connected to the right end of the first horizontal portion 11A via the second bent portion 15B and extends obliquely to the upper left from the second bent portion 15B. One surface of the metal plate constituting the second inclined portion 13B is oriented obliquely in the upper right direction to form the second suction surface 5B.

The third inclined portion 13C is a portion that is connected to the upper end of the first inclined portion 13A via the third bent portion 15C and extends diagonally downward and to the right from the third bent portion 15C. One surface of the metal plate constituting the third inclined portion 13C is oriented obliquely toward the lower left direction and serves as the second bonding surface 3B. The second horizontal portion 11B is a portion that is connected to the upper end of the second inclined portion 13B via the fourth bent portion 15D and extends rightward from the fourth bent portion 15D. One surface of the metal plate constituting the second horizontal portion 11B is directed upward and serves as a first suction surface 5A.

A gap is formed between the third bent part 15C and the fourth bent part 15D, and the opening part 9 is formed between the first horizontal part 11A, the first inclined part 13A, and the second inclined part 13B. 7 are made up. The direction in which the opening portion 9 of the holding portion 7 is directed (hereinafter referred to as the opening direction) is the case where the first bonding surface 3A is soldered to the component mounting surface 53 and the direction in which the second bonding surface 3B is directed to the component mounting surface 53. The direction is different when soldered.

More specifically, looking at the angle between the opening direction and the component mounting surface 53 (hereinafter referred to as the opening angle), in the case of this embodiment, as shown in FIG. 2A, the first bonding surface 3A is When soldered, the opening angle between the opening direction D1 and the component mounting surface 53 is 90 degrees. Therefore, when introducing the held object 55 into the holding section 7, the held object 55 is introduced into the holding section 7 by moving the held object 55 from directly above the holding section 7 downward. I can do it.

On the other hand, as shown in FIG. 2B, when the second bonding surface 3B is soldered to the component mounting surface 53, the opening angle between the opening direction D2 and the component mounting surface 53 is approximately 5 degrees. Therefore, when introducing the holding object 55 into the holding section 7, the holding object 55 is introduced from almost directly beside the holding section 7 (to the left of the holding section 7 in FIG. 2B) to laterally (to the right in FIG. 2B). ), the object to be held 55 can be introduced into the holding section 7.

Note that the opening direction here is a direction perpendicular to the width direction of the minimum opening width in the opening portion 9 (the direction indicated by the double-dashed chain line with arrows at both ends in FIGS. 2A and 2B). In the case of this embodiment, the minimum opening width in the opening portion 9 is between the upper ends of the first slope portion 13A and the second slope portion 13B.

When the second bonding surface 3B is soldered to the component mounting surface 53, the first suction surface 5A and the third bent portion 15C are different from each other, as shown in FIG. 2B. It is configured to protrude further to the left than 5A. That is, in the left-right direction, the left end of the first suction surface 5A is at position P1 shown in FIG. 2B, the left end of the third bent part 15C is located at position P2 shown in FIG. 2B, and the third bent part 15C is It is located at a position that protrudes to the left from the suction surface 5A.

Therefore, when the object to be held 55 is moved substantially downward along the first suction surface 5A, when the object to be held 55 reaches almost right beside the holding part 7, the third bent portion 15C protrudes to the left. The object to be held 55 comes into contact with. As a result, the held object 55 is restrained from moving downward by the third bending portion 15C, so that the held object 55 is moved laterally (rightward in FIG. 2B) at that position and held. An object 55 can be introduced into the holding part 7.

Therefore, unlike the case where there is no part protruding to the left from the first suction surface 5A at a location corresponding to the third bent portion 15C, the object to be held 55 moved downward is placed on the component mounting surface 53. can be prevented from reaching. Therefore, the object to be held 55 can be easily positioned at a position substantially right next to the opening portion 9, and the object to be held 55 can be easily introduced into the holding portion 7.

A first protruding portion 17A is provided on the first inclined portion 13A. The first protrusion 17A protrudes obliquely toward the lower right when the surface mount type clamp 1 is in the first orientation. A second protruding portion 17B is provided on the second inclined portion 13B. The second protrusion 17B protrudes obliquely toward the lower left when the surface mount type clamp 1 is in the first orientation. In this embodiment, the height dimension of the first protrusion 17A and the second protrusion 17B in the protrusion direction is about 0.12 mm. These first protruding portions 17A and second protruding portions 17B suppress displacement of the object 55 held by the holding portion 7 in the direction toward the opening portion 9. Therefore, the object to be held 55 can be held more securely than in the case where the first protrusion 17A equivalent and the second protrusion 17B equivalent do not exist.

[effect]
According to the surface mount type clamp 1 configured in this way, the first joint surface 3A is soldered to the component mounting surface 53, and the second joint surface 3B is soldered to the component mounting surface 53. In this case, the opening direction of the holding portion 7 is different. Therefore, for example, when carrying out the work of introducing the holding object 55 into the holding part 7, a joint surface having a more convenient opening direction is selected from the first joint surface 3A and the second joint surface 3B, The surface mount type clamp 1 can be surface mounted on the component mounting surface 53. This makes it possible to improve the work efficiency when carrying out the work of introducing the object to be held 55 into the holding part 7.

Moreover, the versatility of the surface mount type clamp 1 is increased compared to the case where surface mount type clamps 1 of different shapes corresponding to the above-mentioned different opening directions are prepared respectively. Therefore, instead of using two products with different shapes, it is possible to use one product with a single shape, and the mass production effect can reduce the manufacturing cost of the product.

That is, the present disclosure is not limited to the exemplary embodiments described above, and can be implemented in various forms without departing from the technical idea of the present disclosure.

For example, in the above embodiment, when the first bonding surface 3A is soldered to the component mounting surface 53, the opening angle is 90 degrees, but the opening angle is not limited to this. When the first bonding surface 3A is soldered to the component mounting surface 53, if the opening direction is generally directed upward, for example, if the opening angle is configured to be 50 degrees or more and 90 degrees or less. good.

Further, in the above embodiment, when the second bonding surface 3B is soldered to the component mounting surface 53, the opening angle is approximately 5 degrees, but the opening angle is not limited to this.

Further, either one of the first protrusion 17A and the second protrusion 17B may be provided.

Further, in the above embodiment, the first bonding surface 3A and the first suction surface 5A are configured to be parallel, but the parallelism of these surfaces is determined when surface mounting the surface mount type clamp 1 with an automatic mounting machine. It is only necessary to ensure parallelism to a degree that does not pose a problem. Furthermore, in the above embodiment, the second bonding surface 3B and the second suction surface 5B are configured to be parallel, but the parallelism of these surfaces is determined when surface mounting the surface mount type clamp 1 with an automatic mounting machine. It is only necessary to ensure parallelism to a degree that does not pose a problem. That is, these two sets of surfaces do not have to be completely parallel in a geometric sense. In other words, the opposite direction in the present disclosure does not have to be strictly 180 degrees opposite in a geometric sense, and as described above, parallelism is ensured to a degree that does not cause problems during surface mounting. Any direction is fine.
