Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] This invention relates to a jumper arrangement hβ method in a printing unit.

[Technical background of the era]

BACKGROUND ART Conventionally, when wiring using electric wires (jump wiring) on a printing unit, there have been various methods as described below. In other words, as shown in FIG. 1, a wire 3 is placed on a printed wiring board 1 and wires 3 are wound around the bin 2 using a wirer or a wire machine. A method of wiring the electric wire 3 by soldering it to the hole 4 and the land part, or a method of wiring the parts by soldering it to the hole 4 and the land part, or attaching the parts to the front or back side of the printed wiring board 10.
For example, there is a method in which the electric wire 3 is soldered directly to the lead 6 of an IC (integrated circuit) 5. , [Problems with Background Art] However, the above conventional method has the following drawbacks. In other words, in the method of making holes for pin stand and jump wiring, it is necessary to make a mother turn of the printed wiring board 1 for the jumper 4 wiring, and it is necessary to make a hole for the land and a hole for connecting the jumper 4 wiring. Turn wiring had to be performed, making it unsuitable for high-density component mounting and pattern wiring. In addition, with the method of wiring jumps directly to the component leads, if multiple parts need to be replaced due to defective parts, it is necessary to remove all jumper wiring from the parts, and after replacing the parts. It was necessary to solder the component leads twice and solder the soyamper wiring twice, resulting in extremely poor workability.

[Purpose of explanation]

The purpose of L1 is that there is no need to pattern the printed wiring board for junk wiring, and it is possible to mount components and pattern wiring with high tube density, as well as improve work efficiency when replacing parts. An object of the present invention is to provide a jumper wiring method in a printing unit that is possible.

[invention, (ready-made)]

This invention involves inserting a jumper/socket wiring H isolate into the same hole as a hole for inserting a lead of a component provided in a printed wiring board, and connecting the jump/socket wiring terminal and the lead of the component by, for example, soldering. After connecting and fixing the connection, connect the wiring terminal to the jump,
Similarly, the jumper wiring terminals connected to the leads of other parts are connected by electric wires, and the leads of different parts are connected via the wire terminals and the child wiring terminals [Embodiment of the invention] ] An embodiment of the present invention will be described below with reference to the drawings. The second figure is Jean iJ? A printed wiring board 12' (il- shown) on which wiring is performed using wiring terminals 11. The jumper wiring terminals 11 are inserted together with the leads 14 into the holes 15 into which the leads 14 of a component such as ICl3 are inserted. ing.

The wiring terminals 11 are connected to each other by electric wires 16. FIGS. 3 and 4 are partial cross-sectional views seen from the directions of arrows A and B shown in FIG. 2, respectively.

As shown in FIG. 5, the jumper wiring terminal 1) is composed of an insertion portion 11g into a hole 15 of a printed wiring board 1 and a wire connection portion 11b, and this wire connection portion 1lbK is a jumper wire connection portion 1lbK. Hole 17 for passing electric wire 16 through for easy wiring.
and a semicircular groove 18 are formed.

In other words, when performing jumper wiring using the jumper wiring terminal 11f, the jumper wiring terminal 11f is inserted into the same hole as the lead insertion hole 15 of the ICl3 mounted on the printed wiring board 12. The insertion portion 11a of the terminal 1 is inserted, and soldering 19 is applied from the back side of the printed wiring board 12. As a result, the lead 14 of ICl3 and the jumper wiring terminal 1
1 can be reliably connected and fixed to the printed wiring board 12. After that, it was inserted for Shan i9! Wrap one end of the wire 16 around the hole 17 and groove 18 of the JM element 11, apply the solder 20, and then insert the other end of this wire 16 into the same hole 15 as the lead 14 of the other ICl3. Hole 17 and groove 18 of jumper wiring terminal 1
I rolled it up and attached half E120. This allows the leads 14 of different ICl 3 to be connected via the soyan/child wiring terminals 11.

The jumper wiring terminal 21 shown in FIG. 6 has an insertion tab portion 22 on the wire connection portion 11b in order to improve the ease of inserting the jumper wiring terminal 1 into the lead insertion hole 15 and workability. It is something that A notch 23 is formed between the insertion tab portion 22 and the wire connection portion 11b.
The structure allows the two to be easily separated. That is,
This connector or wiring terminal 2 has an insertion tab portion 22, and after inserting the insertion portion 11a into the lead insertion hole 15, the insertion tab portion 22 is bent, and the insertion tab portion 2
After that, connect the jumper wiring terminal 1 to the jumper wiring terminal 1.
It is possible to perform Jean Gusai fg3 in the same manner as No.

In the method of performing jumper/arm wiring using all of the jumper wiring terminals 11 and 21 described above, the following effects can be obtained.

In other words, ■ pattern design of the printed wiring board 12 for Noyan iR wiring (land and hole wiring and main turn wiring from leads of components to be connected) is not required, and high-density component mounting and turn wiring can be achieved. becomes possible. Also, even if there are design changes, etc., the component lead section will not be affected. This can be easily handled by additionally inserting the wiring terminal 11.21 and wiring it, and the wiring terminal 11.21 can be soldered to the component lead in one soldering operation.

・2) If parts need to be replaced due to failure of parts in the wiring section, etc., replace the parts with the printed wiring board 12.
At the same time as removing it from the jumper wiring shop 1'' child 11.
21 can also be removed without completely separating the terminal 11.21 and the electric wire 16. After the parts are replaced, by returning the wiring terminals 11 and 21 with the electric wires 16 to their original positions and performing the soldering work once, the repair can be made in the same manner as before the parts were replaced. . Therefore, the number of man-hours required for assembling and changing the printing unit can be reduced.

In addition, in the above embodiment, Janno and arrangement 1 terminal 11
．． 21 was explained about how to use it for jumper wiring, but since the hole 17 and groove 18 are formed in the wire connection part 11b, it can also be used as a check terminal during circuit function inspection or testing/adjustment. be.

〔Effect of the invention〕

As described above, according to the present invention, there is no need to perform a turn design of a printed wiring board for jumper/mother wiring, and high-density component mounting and pattern arrangement are possible. It is possible to provide a jumper wiring method in a printing unit that can improve performance.
