It is done by inserting it into the through ball which is the connecting part of the board and attaching it for half a month. Another mounting method is to hold the terminals with a holder and, when attaching the fluorescent display tube to the substrate via the holder, insert the terminals into through holes and solder them.

(Problems to be Solved by the Invention) Recently, there has been a strong tendency for electronic components to have a large number of terminals, and particularly in fluorescent display tubes, the number of terminals has increased considerably as display patterns become more diverse.

However, as the number of terminals increases like this, the terminals often become uneven, and in such cases, it is necessary to correct the large number of terminals so that they are aligned and insert them into the through-holes of the board [2]. However, there was a problem in which the efficiency of the mounting work became extremely poor. In particular, in this fluorescent display tube, it is considered to reduce the cost by changing the terminal from a flat plate to a bottle-shaped terminal with a higher yield, but this pin-shaped terminal is relatively The reality is that it is easy to deform and become irregular, and its practical application has been delayed.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to solve the problem even if there is a defect in the terminal of an electronic component.
It is an object of the present invention to provide a holder for electronic components that can be easily modified to improve the efficiency of electronic component mounting work, and that can also contribute to lowering the cost of electronic components.

The holder body is characterized by comprising an engaging portion and a substantially V-shaped groove portion into which each of the terminals can be inserted at an arrangement pitch interval corresponding to the arrangement pitch of the terminals in the holder main body portion. have (Invention of Claim 1) The invention also provides a method for attaching an electronic component having a plurality of terminals protruding from one side of a rectangular component body to a board, the component body of the electronic component A holder that has a rectangular shape that substantially matches, has a locking portion on the side opposite to the one side of each side, and locks and holds the main body of the electronic component by the locking portion. a main body, an engaging part formed on the holder main body that engages with a holder attachment part formed on the substrate side to attach the holder main body to the substrate, and each side of the holder main body. A groove portion formed in a side portion corresponding to one side of the component body so as to have a substantially V-shape into which each of the terminals can be inserted is arranged at an arrangement pitch corresponding to the arrangement pitch of the terminals. It has the following characteristics. (Invention of Claim 2) In this case, the engaging portion is located on each of the remaining two sides where the locking portion and the groove portion are not present among the sides of the holder main body, and closer to the side where the locking portion is present. They may be formed so as to be positioned and face each other, and to be elastically deformed in directions facing and away from each other to engage with the holder attachment portion (invention of claim 3).

(Function) By locking the component body of the electronic component with the locking portion, the component body is held by the holder body. Then, the holder main body is attached to the substrate by engaging the engaging portion with the holder attachment portion formed on the substrate side. When the terminals of the electronic component are inserted into the grooves during this folding process, since the grooves are V-shaped, they are positioned at the deep part of the grooves, and since the grooves are provided at predetermined pitch intervals, Even if a large number of terminals are not aligned, it can be corrected so that they are aligned.

Even if there is some misalignment between the terminals 3 and the groove 11,
．． When the groove 11 is inserted into the groove 11, the groove 11 becomes V-shaped.
The terminals 3 are positioned at the inner part of the groove 11 (see FIG. 5), and since the groove 11 is stepped at a predetermined pitch, the terminals 3 can be easily corrected to be aligned.

In this embodiment, since the terminal 3 automatically fits into the groove 11 by the above-described slide of the fluorescent display tube, there is no need for even a fitting operation.

After that, each terminal 3 of the fluorescent display tube attached to the holder 7 is inserted into the through pole 5 of the board 4 (see Fig. 6).
. In this case, since the terminals 3 are aligned, the terminals 3 can be accurately aligned with the through-holes 5 of the board 4, and can be easily inserted and connected.

Next, the engaging claw portions 12, 1.2 are attached to the receiving holes 6.6 of the board 4.
Insert and engage. In this way, the fluorescent display tube 1 is attached to the substrate 4 via the holder 7.

In this case, the engaging pawl 12.12 undergoes bony deformation in the direction opposite to the phase 11' (indicated by arrows A, B) and in the direction away from it and engages with the hole 6, 6. After this, the end f-3 is attached to the through hole 5 by half 111.

As described above, according to this embodiment, the holder main body 8 is provided with grooves having a substantially ■-shape into which the respective terminals 3 can be inserted at an arrangement pitch corresponding to the arrangement pitch of the terminals 3 of the fluorescent display tube 1. 1] and then fit each terminal 3 into the groove 1], even if the terminals 3 are uneven, they can be easily corrected to be aligned. Therefore, the terminal 3 of the fluorescent display tube 1 can be accurately and easily aligned with the through hole 5, which is the connection part of the mating board 4. As a result, the efficiency of the mounting work of the fluorescent display tube 1 can be improved. In addition, for terminals 3, 1, and It can also contribute to lower prices.

Further, in this embodiment, considering that the fluorescent display tube 1 has a structure in which the terminal 3 protrudes from one side 2a of the fluorescent display tube main body 2 having a rectangular shape, the holder main body 8 is It has a rectangular shape that almost matches the display tube main body 2, and a part 10, 10 of the fluorescent display tube main body 2 is white on the side 8b opposite to the above-mentioned side 2a. Forming 5, groove] 1
is formed on the side 8a of the holder body 8 that corresponds to the side 2a of the fluorescent display tube body 2 among the sides 8a, 8b, 8e, and 8d. When the terminal 3 is folded to be locked, the end f3 can be automatically fitted into the groove 1, thereby making the work for fixing the terminal 3 easier.

The terminal 3 is inserted while the terminal 2 is not yet inserted. If such a work procedure is adopted, as can be seen from FIG. 6, when the terminal 3 is inserted into the through hole 5, the holder main body 8 will be at a certain angle (indicated by the symbol α) with the substrate 4. If this angle α is large, there is a risk that the terminal 3 may be bent. However, in this embodiment, the engaging claw portion 1.2.12 is formed closer to the side portion 8b where the locking portions 10, 10 are located. Since it is kept away from the terminal 3, the above-mentioned angle α can be made small, and there is no risk of the terminal 3 being bent due to (4). Furthermore, the engaging claws 12, 12 are configured to be elastically deformed in the direction facing each other or in the direction away from each other to engage with the mounting holes 6, 6, so that the engaging force is applied to the terminal. 3, no excessive external force is applied to the terminal 3 during the engagement operation of the engaging claw part 12 with the access hole part 0, and this also eliminates the risk of protrusion.

In addition, in Example 1-1, a fluorescent display tube is exemplified as the electronic component 5. However, the present invention can be widely applied to liquid crystal display devices and other electronic components in general, and the gist of other electronic components is also described below. Various changes and modifications may be made within the scope of the invention.

[Effects of the Invention] As is clear from the explanation in section 8 above, the present invention can obtain the following effects.

According to the electronic component holder of claim 1, the end r of the electronic component
Even if the electronic components are not aligned (2), they can be easily corrected to the aligned state, and the end T- of the electronic component can be easily aligned with the connection part on the board side. As a result, it is extremely easy to mount electronic components on a board, and there is no problem in using bottle-shaped terminals with high yields instead of flat terminals for electronic component terminals. It can contribute to lower costs.

According to the electronic component holder of claim 2, in addition to the above-mentioned effects, the terminal can be automatically fitted into the groove when folding the electronic component to lock it in the locking portion. It can make the work for the person even easier.

According to the electronic component holder of claim 3, in addition to achieving these effects, the position of the engaging portion is moved away from the terminal, so that when the terminal is inserted into the connecting portion of the board, the terminal is not inserted. Since bending can be eliminated, and the elastic engagement force of the engagement part is not applied to the terminal, L5 is designed so that no force is applied to the terminal when the engagement part is engaged with the holder attachment part of the board. Since no external force is applied, L is obtained without the risk of deformation.
