It is explanatory drawing shown by.
[Configuration of board terminal structure]
As shown in FIG. 1, the board terminal structure according to the present embodiment includes a board terminal block 10 and a board 12 on which double-side mounting is performed.
  The substrate terminal block 10 is made of an insulating material such as a synthetic resin, and has a block shape that is bonded and fixed to the end surface of the substrate 12 on one side surface of a horizontally long plate-shaped terminal block body 14. A temporary fixing part 16 is formed.
  As shown in the side view of FIG. 3B, the upper surface of the temporary fixing portion 16 is formed flush with the upper surface of the terminal block body 14, but the lower surface of the temporary fixing portion 16 is a terminal. A step portion is formed which is located above the lower surface of the base body 14 and is arranged with the end face of the substrate 12 facing the terminal base body 14.
  A plurality of lead terminals 18 made of a conductive material are arranged on both the left and right sides of the temporary fixing portion 16 formed in the terminal base body 14. The lead terminal 18 is embedded and fixed when the terminal block main body 14 is manufactured by injection molding of synthetic resin, and terminal tip portions 18 a and 18 b extend on both front and rear sides of the terminal block main body 14.
  Here, as shown in FIG. 3B, the lower surface of the lead terminal 18 is disposed at a position that coincides with the lower surface of the temporary fixing portion 16 integrally formed on one side of the terminal base body 14. As shown in FIG. 4, when the temporary fixing portion 16 is placed on the portion where the terminal of the substrate 12 is provided and bonded and fixed, the terminal tip portion of the lead terminal 18 extending from the terminal base body 14 to the substrate 12 side. A state where the lower surface of 18a is placed in contact with the circuit pattern formed on the surface of the substrate 12 is created.
  The number of the lead terminals 18 is five in this embodiment, but is determined as appropriate according to the mounting components of the board 12 to be mounted. Further, the lengths of the terminal tip portions 18a and 18b of the lead terminal 18 are also determined as appropriate as required.
  3A, when the number of the lead terminals 18 is five, the temporary fixing portion 16 divides the lead terminals 18 into three and two from both ends of the terminal base body 14. Since they are arranged at equal intervals, the temporary fixing portions 16 are arranged at positions offset from the center of the terminal block main body 14 toward the two lead terminals 18.
  On the other hand, when the number of the lead terminals 18 is an even number, the temporary fixing portions 16 are integrally formed at the center position of the terminal base body 14.
[Assembly of PCB terminal structure]
The assembly of the substrate terminal structure shown in FIG. 1 and FIG. 3 is a circuit chip in which the substrate terminal block 10 is applied to the substrate 12 with the soldering cream applied to the position of the circuit pattern that requires soldering of the substrate 12. Like a circuit device or the like, it is prepared as a single mounting component, for example, using a mounter prepared as equipment, and as shown in FIG. By placing the adhesive 10 on the back surface of the temporary fixing portion 16 in the table 10 or the surface of the substrate 12 that the temporary fixing portion 16 contacts, and fixing the temporary fixing portion 16 to one surface of the substrate 12, Temporarily fix.
  When the substrate terminal block 10 is arranged on the substrate surface, a component 20 such as a circuit chip indicated by an imaginary line in FIG. 3 is also arranged on the substrate 12 surface by the mounter.
  Subsequently, the board 12 on which the board terminal block 10 and the component 20 are arranged is passed through a reflow soldering process, and is fixed by the solder fixing portion 22 as shown by dotted lines in FIGS.
[Advantages of PCB terminal structure]
Thus, the board terminal block 10 of the present embodiment can be handled as a component similar to a connector in which the terminal tip portions 18a and 18b of the plurality of lead terminals 18 are extended on both sides of the terminal block body 14. As with other circuit components that are surface-mounted on the board 12, the board terminal block 10 is arranged on one side of the board 12, the temporary fixing part 16 is bonded and fixed, and then soldered and fixed in a reflow soldering process. As a facility equipment, no equipment other than the mounter is required, reducing the number of production steps and equipment costs.
  In addition, since the base terminal block 10 only needs to be mounted on one side of the substrate 12, it is possible to reduce the size of the substrate without restricting the arrangement space of components because it is mounted on one side compared to the double-side mounting. .
[Modification of the present invention]
In the above embodiment, the block-shaped temporary fixing portion 16 is integrally formed with the terminal block main body 14 of the substrate terminal block 10. However, the temporary fixing portion 16 is not limited to the block shape, and is, for example, cylindrical or semicircular. An appropriate shape such as a column shape may be used. Further, the number of the temporary fixing portions 16 may be provided at a plurality of locations when the terminal base body 14 is long and the number of the lead terminals 18 is increased.
  Further, the present invention includes appropriate modifications that do not impair the object and advantages thereof, and is not limited by the numerical values shown in the above embodiments.
