DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relay mounting wiring device and a relay mounting method for a printed wiring of a relay of a door lock control unit of an automobile.

[0002]

2. Description of the Related Art FIG.
FIG. 3 is a diagram illustrating an example of an electronically controlled door lock system that locks or unlocks (unlocks) a door lock motor M of an automobile using three make-break relays RLY1 to RLY3. Here, the CPU 1 operates the three transistors T31 to T3 by remote control of the operator or the like.
3 is provided with an instruction signal.

FIG. 8A shows relays RLY1-RLY.
LY3 is a perspective view, and FIG.
FIG. 1C is a diagram showing the internal configuration of the same. These relays RLY1 to RLY3 are all shown in FIG.
As shown in (B), five lead terminals Tm1 to Tm5 are provided on the bottom surface.
The exciting coil 3 is connected between the first lead terminal Tm1 and the second lead terminal Tm2, and the third lead terminal Tm3 as shown in FIG.
Is configured such that a predetermined contact 4 is selectively switched and connected to a fourth lead terminal Tm4 and a fifth lead terminal Tm5 in accordance with the on / off of the current in the exciting coil 3.

At the time of unlocking, as shown in FIG.
When the CPU 1 switches on the unlocking transistor T33, the corresponding relay RLY3 connects the one terminal α of each door lock motor M and the power supply Vcc1 to each other. At this time, the locking transistor T32 is off, whereby the relay RLY2 grounds the other terminal β of each door lock motor M. Accordingly, the drive current from the power supply Vcc1 is supplied from one terminal α of each door lock motor M through the relay RLY3, and furthermore, the door lock motor M is unlocked by passing through the other terminal β to the ground through the relay RLY2. Will do.

On the other hand, at the time of locking, when the CPU 1 switches on the locking transistor T32 based on an instruction from the operator or the like, the corresponding relay RLY2 connects the other terminal β of the door lock motor M to the power supply Vcc1. At this time, the transistors T31 and T33 are turned off, the relay RLY1 is grounded, and one terminal α of the door lock motor M is connected to the relay RLY1 through the relay RLY3.
LY2 from the other terminal β of each door lock motor M, and further from one terminal α to relays RLY3, RL.
By exiting to the ground side through Y1, the door lock motor M is locked.

Incidentally, reference numerals P25 to P2 shown in FIG.
Reference numeral 7 denotes a signal output terminal of the CPU 1, reference numerals R70 to R72 denote resistors, reference numerals D24 to D26 denote back electromotive voltage suppressing diodes of the relay, and D27 and D28 denote backflow preventing diodes.

Incidentally, there is a device that automatically releases (unlocks) a door lock in order to help a driver or the like escape from an automobile when a great impact is applied to the vehicle such as in a collision accident. In particular, in an electronically controlled door lock system in which an electronic unit controls a door lock motor, the door lock / unlock is performed by the CPU 1 as described above.
Is provided in advance, and after detecting an impact with the impact sensor IS or the like using such a function, the transistors T31 to T3 are determined based on the detection.
3 and the relays RLY1 to RLY3 to automatically unlock the door lock motor M.

Here, it is desirable that the components be duplicated in order to enhance reliability so that the device operates even when subjected to a strong impact at the time of a collision of the vehicle. In consideration of such circumstances, in the example of FIG.
The system is controlled by two power supplies (two power supplies).

That is, when a strong impact is detected by the impact sensor IS, the CPU 1 first turns on the first unlocking transistor T33 and turns on the relay RLY3.
And the first terminal α of the door lock motor M is connected to the first power supply Vcc1. At this time, the relay RLY2
Is grounded, the other terminal β of the door lock motor M is grounded through the relay RLY2. As a result, the door lock motor M is unlocked.

Next, the CPU 1 turns off the first unlocking transistor T33 to switch the relay RLY3,
One terminal α of the door lock motor M is connected to the relay RLY1 and the second unlocking transistor T3
1 is turned on to switch the relay RLY1 to the second power supply Vcc2 side. As a result, the current from the second power supply Vcc2 is supplied to the one terminal a of the door lock motor M through the relays RLY3 and RLY1.

As described above, the two power supplies Vcc1 and Vc
By driving the door lock motor using c2, it is possible to normally unlock even if one of the power supply paths is disconnected or the fuse is blown during a collision.

[0012] The dual power supply as described above is often installed only in high value-added automobiles of high-end models, and generally only one power supply is used in popular models that require low cost. A single-system power supply as shown in FIG. In this case, the transistor T31, the relay RLY1, and the like used in the luxury vehicle are omitted.

However, for the purpose of reducing the manufacturing cost, the circuit for the high-end model and the circuit for the popular model are configured by using the same type of printed circuit board. That is, as shown in FIG. 10, mounting areas for all the relays RLY1 to RLY3 are provided so that they can be used as a circuit for a high-class vehicle (however, the mounting area for the relay RLY2 is not shown), and is widely used. When used as a vehicle type circuit, the relay R is mounted in the mounting area Ar1 of the relay RLY1.
The mounting of LY1 was omitted, and instead, a jumper wire Jp1 was mounted as shown in FIG. Thus, the relay RLY3 functions to properly select the connection to the first power supply Vcc1 and the ground even when the relay RLY1 is omitted.

Further, an inexpensive jumper wire Jp2 may be mounted in place of the diode D27 which is not particularly required.

That is, in the case of the above configuration, it is necessary to mount the jumper wire Jp1 at the time of manufacturing a circuit for a popular vehicle type. However, considering the efficiency of the assembling process, the jumper wire Jp1 is mounted to ground the relay RLY3. To do so increases the number of parts and man-hours, so there has been a demand to omit such parts and man-hours if possible.

As in the case of the circuit for a high-end vehicle model shown in FIG. 10, a relay RLY1 is mounted in the same manner when used as a circuit for a popular vehicle model, and the relay RLY is always controlled in the control by the CPU 1. A method of maintaining the connection state to the ground side is also conceivable. However, if the relay RLY1 is only mounted for the purpose of grounding,
Even though it is a popular model, it uses the same parts as those used for high-end models, and the cost of parts cannot be reduced. Moreover, in this case as well, it is desirable to omit the step of mounting the relay RLY1 as in the case of mounting the jumper line Jp1.

Therefore, an object of the present invention is to provide a circuit for a popular vehicle model by using the same type of printed circuit board for both a circuit for a luxury vehicle model and a circuit for a popular vehicle model. It is an object of the present invention to provide a relay mounting wiring device and a relay mounting method that can reduce the number of parts and omit the above.

It goes without saying that the present invention can be applied to any circuit device as long as it can drive the other device without delay, even if it is interrupted due to an accident or the like.

Further, in each of the above embodiments, the type in which the lead terminal of the relay is inserted into the through hole as the terminal connection point has been described, but the surface mounting type relay mounting in which the land is formed as the terminal connection point. May be applied to a wiring device for use.

[0063]

According to the first to fifth aspects of the present invention, when the design of the mounting of a predetermined relay is changed, the connection destination is maintained for some terminals, while other terminals are connected. When it is desired to route some of the terminals to another mounting component mounting area, a predetermined relay (first relay) is moved to a first position and a second position in a predetermined mounting area (first mounting area). By simply changing the design, the design change can be easily achieved.

More specifically, according to the second to fifth aspects of the present invention, the first relay in the first mounting area depends on the presence or absence of the second relay in the second mounting area. If the mounting position is changed to the first position and the second position, the second relay can be omitted in the second mounting area without adding a jumper wire or the like in place of the second relay when it is desired to omit the second relay. One relay is connected to a predetermined potential point (for example,
In this case, a jumper wire connecting the first relay and a predetermined potential point is used as a substitute for the second relay, and the number of man-hours can be reduced. The number of parts can be reduced.

In particular, according to the second, third and fifth aspects of the present invention, when both the first and second power supplies are used, the first relay is provided in the first mounting area. Is placed in the first position and both of the first and second relays are mounted to provide a dual power supply system. On the other hand, when only the first power supply is used, the second power supply system is used in the second mounting area.
A single power supply system is realized by omitting the relay of
By simply arranging the first relay in the second position in the mounting area, the design can be easily changed.
Therefore, it is possible to easily increase or decrease the number of relays in accordance with a change in the presence or absence of the second power supply as a standby power supply.

Further, in the third aspect, a part of the through-hole is used as a common through-hole and the first through-hole group and the second
Is shared by the through-hole groups, and therefore, it is possible to partially omit the wiring pattern connecting the two through-hole groups, and to simplify the pattern design.
