Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spacer for a printed circuit board connector that allows the insertion margin and insertion depth of a printed circuit board to be changed.

As shown in FIGS. 1 and 2, a printed circuit board Pi.

The pitch of the conductor 2 arranged in the connector insertion part 1 of P2 and the connector A1. The pitch of the contacts 3 of A2 is standardized into several types, but even if they have the same standard conductor pitch, the width of the ear margin 4 of the connector insertion part 1 may differ depending on the printed circuit boards Pl and P2. The actual situation is that there is a difference in the insertion width (opening width) Wl and W2 of the insertion part 1, and in such a case, the conductor 2 and the contact 3
Even though the pitches of the printed circuit boards P, ,
Different types of connectors A1.P2 each have a corresponding printed circuit board insertion groove 5. A2 must be prepared, which is not only extremely uneconomical, but also inconvenient in the printed circuit board mounting work at the site.

Therefore, the present invention is based on the above-mentioned printed circuit board P1. When the insertion allowance of P2 is different, and when the connector A1. This was provided to effectively deal with the case where the depth of the insertion groove 5 of A2 differs depending on the manufacturer, and also the case where the insertion depth of the printed circuit board itself also differs. , spacers are removably inserted into both ends of the printed circuit board insertion groove 5 of the connector A1 to change the insertion margin (insertion opening width, insertion depth, and insertion level) of the insertion portion 1 of the printed circuit boards P, P2. Therefore, the same type of connector A1 can be connected to two or more types of printed circuit boards P1. This makes it possible to apply P2.

FIGS. 3 to 5 show, as an example, a spacer 7B cut from a pair of insulating materials that regulates the corner side and end surfaces of a printed circuit board.

The spacer 7B has a key portion 7a that is inserted into the short-side middle direction of the printed circuit board insertion groove 5, and the connector A1 has a pair of left and right key grooves 6 on the inner wall of the groove to receive the key portion 7a.

The spacer 7B has an insertion margin setting ruler part 7B' which has equal thickness on the left and right sides or unequal thickness depending on the implementation, with the center line connecting the two parts 7a as a reference line, and the printed circuit board P
A ruler surface 7b is formed to regulate the left and right corner side surfaces of the connector insertion portion 1 of No. 2.

4th. As shown in FIG. 5, the pair of spacers 7 are inserted into the key grooves 6 at both ends of the printed circuit board insertion groove 5 having the groove length W1.
By inserting B, the groove length W1 can be converted to W2.

With this groove length W2, a printed circuit board P2 having the same short insertion clearance W2 can be received.

That is, it is possible to convert the printed circuit board P1 with a long insertion length W1 to P2 with a short insertion length W2 according to the above.

Also, if you pull out spacer 7B, insert it in the opposite direction from W2 to W1.
It is possible to convert to

Furthermore, the spacer 7B includes an insertion margin setting ruler part 7B' that regulates the corner side surface of the connector insertion part 1 of the printed circuit board P2, and an insertion depth setting ruler part 7B'' that regulates the corner end face of the connector insertion part 1. be equipped with.

The spacer 7B is configured such that the insertion margin setting ruler part 7B' and the insertion depth setting ruler part 7B'' have an abbreviated shape when viewed in cross section, and the insertion margin setting ruler part 7B' is connected to the key 7a.
Insert the printed circuit board into the key grooves 6 at both ends of the printed circuit board insertion groove 5 to fix the position, and insert the ruler part 7B'' for setting the insertion depth.
is placed on the bottom surface of the insertion groove 5, and its upper surface is used as a ruler surface 7C to support the corner end surface of the insertion part 1 of the printed circuit board parallel to the bottom surface of the insertion groove, thereby converting the insertion depth of the printed circuit board from G1 to 62. This was done in a deliberate manner.

As described above, it is possible to switch between the printed circuit board insertion depths Wl and W2, and the printed circuit board insertion depth G1. G
2 mutual conversion is possible.

The above embodiments are applicable when the opening width of the connector insertion portion 1 is long or short, when the depth width is long or short, or when the connector A1. If there is a difference in the depth of the insertion groove 5 of A2 itself, it can be effectively dealt with by using the pair of spacers 7B, and the insertion margin can be set while keeping the protrusion level of the printed circuit board constant at all times. .

In FIG. 6, the thickness is different on the front and back sides with the reference line connecting the keys 7a as a boundary, the first ruler surface 7b is on the thinner side, and the second ruler is on the thicker side.
Insertion margin setting ruler parts 7D' each having a ruler surface 7b formed thereon.
A case is shown in which a spacer 7D is provided with an insertion depth setting ruler section 7D'' having the third ruler surface 7C.

If a pair of the same spacers 7D are used for connector A2 as described above, the first ruler surface 7b will correspond (example of use of X1 in the figure).
It is possible to convert the insertion clearance from the printed circuit board P1 to P2, and it is possible to convert the insertion clearance W3 to a printed circuit board with a shorter insertion width by matching the second ruler surface 7d (example of use of X3). .

Also, while making the second ruler surface 7d correspond, the third ruler surface 7C
Insert it into both ends of the insertion groove so that it faces upward (X2
(Example of use), it is possible to convert to the insertion depth W2, and also to convert from the insertion depth G1 to 62.

Although not shown, the present invention includes a case where two or more pairs of the key grooves 6 are provided so that the inserting positions of the spacers 7B and 7D can be selected and the insertion margin can be changed.

According to the present invention, it can be applied to cases where a long connector of one type is inserted, two or more types of printed circuit boards with different insertion depths, or where the depths of the insertion grooves 5 of the connectors themselves are different. , the uneconomical need to prepare a connector for each printed circuit board as in the past has been eliminated, and in field mounting, you can simply insert a pair of spacers into an existing connector as described above without removing the connector from the board. It is possible to convert to printed circuit boards.

Since a mechanism is adopted to support both sides of the left and right corners of the connector insertion part 1 of the printed circuit board and the end face of the same corner, stable support can be achieved and the contacts 3 and conductors 2 can be accurately matched.
