Description

[Detailed description of the invention] object of invention The present invention relates to a connector for a printed wiring board.

A connector that can be used as an elancoy cover for conventional technology logic cards and a convenient mounting method of 7 is provided.

Fll in FIG. 1 is a coil cover 4 which is arranged to sandwich the edge portion of the printed wiring board 1 between the upper two rows of contact leads 7 and 7' extending from the lead blood ρ) of the connector 4.
Attach. Then, the contact leads 7, 7' are soldered to the notches on the printed wiring board 1. Signals are exchanged between the printed wiring board 1 and the outside through a signal cable io+- connected to the edge card 9, which is connected to the edge card 9 by inserting it into the coil cover 4.

In this example, the position where the connector 4 is attached on the printed wiring board 1 (- indicates that another connector cannot be attached. Therefore, the distance between the printed wiring board 1 and the outside is It is not possible to do too much.Also, the danger of connector 4 is
When the contact lead 7.7' is deformed, the coil cover 4
It will be difficult to install it on the printed Kamosenjo Kari 1.

The holes in Figure 2 are for mounting the connectors 5 and 6 on the same position on the wiring board 1 and the rear side (2).Be careful of the lead spacing between the coil lids 5 and 6. The contact leads 8 and 8' in the upper 132 rows are inserted into the through holes of the wiring and handling IL at right angles (concave by two strokes, marked All 1) at the correct position, and then soldered to the pattern. .The signal connection between the printed wiring board and the outside is 15 in Figure 1.
Similarly to 11, this is done using the Edge card 9 and the Tsukuda cable 10.

At this side J, attach the carp lids 5 and 6 on the moat side and the reverse side 11117J to the same position of the mark A11ll J base 1, so from the Noshi 1 in Figure 1, the number 1 is I can stomach it. However, the +tr song position of IJ-do is different between Tatsu 111 and connectors 5 and 6 on the back side, and I have to prepare a carp lid for Jijika (22 God Kou).

Also, since the contact leads 8 and 8' are pushed into the through-hole of the printed wiring fist and Saka 1 and soldered, the coil, the lid 5
．． 6.Installation of the contact lead V1 is a bit quiet, and the space between the contact lead connection and the contact lead tends to make noise.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a connector which eliminates the various drawbacks of the above-mentioned conventional technology.

The connector of the present invention has a number of contact leads protruding side by side. The whole is U-ji, and its tip is one piece, and it is formed into a row (like two rows).

In the center of the starting point, there is a drawing (2?d) about the IJ of the present invention.
invent.

The third figure shows the present invention (two carp, -i+1 of the lid), the same figure (a) is a plan view, the same figure (a) is a front view, and the same figure (
→ is the rear view, the same figure (→ is the J song diagram.

50 is the housing of the connector, and its −1 μs 1j
Contact leads 52 (upper row) and 53 (upper row) are set in the II (lead surface) 51 (-1, F2 row (two rows).The contact leads 52 and 53 are connected to the corresponding 1- The width is 54°55, and it is compensated for when the contract is concluded, but - from a sales perspective, the contact lead is 5.
2, 53 and contacts 54, 55 are integral (made as one).

Above the lead recess 51, the contact leads 52 and 5
3 and the arrangement pitch are the same, and the positions of the second and upper contact leads 52 and 53 in the direction of the housing receiver also do not match. However, as shown in FIGS. 3(1) and (b)(-), the upper contact lead 52 is bent by 1/4 pitch toward the E side in the figure at the part near the proximal end. The contact lead 53 has a base end 2!r, and a 1/4 hit is bent to the stone surface next to it.The contact leads 52 and 53 are bent as shown in Figure 3).
It is bent downward at an angle of 1 inch from the middle, and the tip (...) is almost 1 f long at the bottom of the Uzing 50.
The contact lead 52, 5:II->Tip part The optical end of each contact lead 52 and 53 is attached to the housing 50 to prevent it from floating up from the pattern.
I think it would be a good idea to position it a little further down than the bottom of 58. Further, the base ends of the contact leads 52 and 53 are
In order to improve the airmanship with Baku-/ (2, ha is made to be a horizontal rotation, and the most advanced pattern is 1 easy to see and stop blue's point of view ρ). ``Hane'' - I'm getting angry.

Thus, the base ends of the contact leads 52 and 53 are arranged in a straight line at 1/2 pitch, as clearly shown in the third b) and b).

The connector +u of this example will be explained with reference to FIG.

In the figure, 60 is the connector of the present invention described above, and 1 is a printed wiring board. Connector 6 to the front side 1g1l of the edge part of the printed wiring board 1 and the back side 1g1l, respectively.
0 cars are fixed. This fixing can be achieved by inserting an ink into the hole 57 and the printed wiring board 1, for example, and tightening it by 0.degree. C., or by riveting. The tips of the contact leads 52 and 53 of each connector 60 are formed into corresponding patterns on the printed wiring board &1 by means of the elasticity of the contact lead plain wood. G-layer. After that, solder the tip of the IJ-do to the pattern. By the way, as described in 111J, if the contact lead end is formed on the bottom of the housing, the tip of the contact pattern will be raised. It is effective in preventing poor connections.
be.

The signal connection between the printed wiring board 1 and the outside is as before.
This can be done using the Edge card 9 and the signal cable 10.

A modification will be explained with reference to a perspective view in FIG. 5(a) and a side view in FIG. 5(o).

This 9+1 connector has contact leads of 52°53
The tips of the two are connected xx by a common bar part 62. The tip of each contact lead is at the lowest position, which is a distance t below the bottom surface 58 of the housing 50.

As described above, t is determined to be a dimension that can prevent the tips of the contact leads 52 and 53 from floating from the pattern 65 of the printed wiring board 1 by 1'J5 during mounting.

This connector is attached to the printed circuit board 1 with the contact leads 52 and 53 connected by a common bar part 62, and the tips (soldered parts) of each contact lead 52 and 53 are attached to a pattern 65. After soldering, the common bar part 62 is bent upward and cut and separated using the cutting property 63, thereby allowing mounting.

In this connector, the tips of each contact lead 52 and 53 are connected by a common bar part 62, so that deformation of each contact lead does not occur before and during mounting process, and each contact lead The tip can be reliably added with a constant bit. For this reason, storage of connectors,
It is easy to transport and handle, and there are no defects in soldering during mounting.
i! It is completely preventable.

Note that in this example, the upper and lower contact leads 52 and 53 are all connected by a common bar part 62, but the upper contact lead 52 and the lower contact lead 53 are connected by separate parts of the bar. You can also do this.

Furthermore, although all of the engineers have contact leads in two rows of upper and lower rows, it is clear that it is also a good idea to arrange the contact leads in three rows u.

Effects of the Invention As is clear from the above description, the connector according to the present invention can be accommodated in any desired position of a printed wiring board, stacked on both the front and the outside, and can draw out a large number of signals. can. In addition, since the contact leads are not passed through through holes and soldered, it is easy to install and replace the connector, and less space is required for connecting the leads. Connection status can also be easily checked.
