Abstract

PURPOSE:To enable mounting of electronic parts even when the surface of substrate on which they are mounted is bent back before soldering operation is applied by providing the connection part between the mutual units of the electronic parts with flexibility. CONSTITUTION:Each short plug unit l is composed of a pair of L-shaped connection members 2, 2 arranged at a specified interval, an insulator 3 for insulating them and a base 5 to mount them on a mounting substrate 4. The bases 5, 5 are connected with a flexible connection part 6. Even if the substrate 13 is bent due to certain reason to generate uneveness thereon, the unit l can cope with it. Namely, even if the surface of substrate 13 is bent before and after the application of soldering, the unit can cope therewith.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a surface-mounted electronic component that is surface-mounted on a mounting substrate, for example, a device in which a plurality of shorting plug units that short-circuit two circuits are connected.

[Prior Art] Conventionally, as shown in FIG. 8, this type of short plug is made up of short plug units 10 that have an upper decimal number, and each short plug unit 10 has an L-shape.
It consists of a pair of connecting bodies 11, an insulator 12 that insulates these connecting bodies 11, and a base 14 for mounting these on a mounting board 13, and each short plug The units 10, especially the bases 14, are integrally connected.

Each short plug unit 10 has a short-circuiting body 21 that short-circuits the connecting bodies 11, as shown in FIG. Plug cover 2 consisting of cover 22
0 allows short circuit.

[Problems to be Solved by the Invention] The conventional short plug shown in FIG. 8 has a structure in which the base 14 portion is integrally connected.
If the mounting board 13 is flat, there is no similar problem. However, if the mounting board 13 is warped before surface mounting and unevenness occurs on the mounting surface, it is necessary to deal with it only with the tail part of the connecting body 11. Implementation may be impossible. Furthermore, if the mounting board 13 is warped after surface mounting, stress may be applied to the printed pattern of the mounting board 13, resulting in poor soldering.

Therefore, it is an object of the present invention to provide a surface-mounted electronic component that is capable of following the warping of the mounting surface of a mounting substrate before or after soldering.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention includes a mounting substrate in which a plurality of electronic component units to be surface mounted are mounted, in which the electronic component units are connected to each other by a connecting portion. , is characterized in that the connecting portion is flexible.

[Function] According to the present invention, since the connecting portion has flexibility,
Even if the mounting surface of the mounting base is warped before or after soldering, it is possible to follow the warping accordingly, and the above-mentioned problem can be improved.

[Examples] Examples of the present invention will be described below with reference to the drawings. Here, we will explain using a short plug as an example.
The present invention is not limited to this, and other surface-mounted electronic components may be used.

FIG. 1 is a perspective view showing a shorting plug according to the present invention, which consists of a plurality of shorting plug units 1 (8 in this case), and each shorting plug unit 1 has a pair of substantially L-shaped connections. It consists of a body 2, an insulator 3 that insulates the connecting bodies 2, which are arranged at a predetermined distance from each other, and a base 5 for mounting these on a mounting base 4 (FIG. 2). The bases 5 are connected to each other by a connecting portion 6, and the connecting portion 6 is structured to have flexibility.

The configuration of this connecting portion 6 is as shown in FIG. FIG. 5(a) is a plan view showing a state in which two short plug units 1 are connected, and FIG. 5(b) is a plan view showing a state in which two short plug units 1 are connected.
FIG. 5(C) is a sectional view taken along line BB in FIG. 5(a) and viewed in the direction of the arrow C; FIG.

As is clear from this figure, the connecting portion 6 has an approximately octagonal cross section when viewed from the direction of arrow C, and has dimensions of, for example, 0.2 a.
Each corner of a rectangle 6a smaller than v is chamfered (chamfered portion 6b), and the short plug unit 1 has flexibility and can be separated by bending. When separating the short plug unit 1, it is necessary to apply a slightly larger force than when obtaining flexibility without separating the short plug unit 1.

The structure other than that described above is similar to the conventional short plug shown in FIG. 8, and is formed so that the contact portion 2a of the connecting body 2 is exposed on the opposing side surface of the insulator 3. In addition, guide grooves 3b for facilitating insertion of the plug cover 20 shown in FIG. 3(a) are formed on the opposite side surfaces of the insulator 3, which are different from the contact portion 2a. Further, a notch 5a for preventing flux from rising is formed on the bottom side of the base 5, that is, in the portion where the surface mounting portion of the connecting body 2 is present.

In this way, since the connecting portion 6 has a flexible structure, even if the mounting board 13 warps for some reason and unevenness occurs on the mounting surface, as shown in FIG. The short plug unit 1 can follow this accordingly. In this case, even if the mounting surface of the mounting board 13 warps before soldering or after soldering, the short plug unit 1 can follow accordingly. Further, since the connecting portion 6 can be separated by bending, it is possible to use only one short plug unit 1 as shown in FIGS. 3 and 4, or to connect a desired number of short plug units 1.

6 and 7 are a perspective view and a front view showing other embodiments of the short plug to which the present invention is applied, and show the connecting portion of the base 5 that connects the short plug units 1 to each other. It was done as follows. The ends of the bases 5 facing each other are formed to have an arcuate cross section, and the tops of the arcuate portions are connected to each other.

In the case of this embodiment as well, the same effects as in the above-mentioned embodiment can be obtained.

Both the short plug unit and the plug cover of the above embodiments are manufactured by insert molding, for example.

[Effects of the Invention] According to the present invention described above, since the connecting portions that connect the electronic component units are made flexible, the mounting surface of the mounting base is placed at the front for soldering or at the front for soldering. It is possible to provide a surface-mounted electronic component that can be warped even if it warps later.
