Field of the Invention The present invention relates to a current detection resistor for detecting a current by a current detection resistor connected between circuits to detect an abnormality such as a lamp cutoff of a vehicle. Related to the connection structure. 2. Description of the Related Art FIGS. 8 to 10 show a conventional connection structure of a current detecting resistor (for example, Japanese Patent Laid-Open No. 10-828).
No. 16). In this structure, a shunt resistor 46 as a current detecting resistor is provided on an electronic circuit board 45, and the printed circuit 4 at both ends of the shunt resistor 46 is provided.
A current detecting element (current detecting unit) 52
(FIG. 10). By detecting the current value, a lamp burnout, an abnormality of the device, and the like are detected. [0003] Both ends of the shunt resistor 46 are connected to printed circuits 47 and 48 via solder holes 50 (FIG. 9) through insertion holes 49 of an electronic circuit board 45. Various electronic components 51 (FIG. 8) are provided on the electronic circuit board 45. The shunt resistor 46 and the current detection element 52 (FIG. 10) are both provided on the electronic circuit board 45. Electronic circuit board 45
Is housed in an electrical junction box (not shown) together with or separately from a bus bar wiring board (not shown). The printed circuits 47, 4 of the electronic circuit board 45
The value of the current flowing through 8 is detected by the voltage drop across the shunt resistor 46. Here, if the resistance value of the shunt resistor 46 is too small, the voltage drop during energization is too small to be detected, so that a certain resistance value (about 10 mΩ) is required. However, if the resistance value of the shunt resistor 46 is increased, the amount of heat generated by the shunt resistor 46 increases when a large current is applied, and the solder 50 for connection may melt. A defect such as softening or adversely affecting other electronic components occurs.
If the resistance value of the shunt resistor 46 is reduced to suppress heat generation, it becomes very difficult to detect a minute current as described above. In addition, it is necessary to form the printed circuits 47 and 48 with a large thickness and a large width in order to supply a large current to the electronic circuit board 45, thereby increasing the size of the electronic circuit board 45 and the electric connection box itself. There was a problem. In view of the above, the present invention does not adversely affect the heat generated by the heat generation on the solder portion or other electronic components even when a large current flows through the current detecting resistor having a large resistance value. It is an object of the present invention to provide a connection structure for a current detection resistor that can prevent the electronic circuit board and the electric connection box itself from being enlarged due to a current circuit. [0007] In order to achieve the above object, the present invention connects a current detecting resistor between bus bars ,
In the connection structure of the current detection resistor which connects the current detection unit to the bus bar, the bus bar is arranged on the wiring board, the
A pressure contact portion having a pressure contact slot in the bus bar;
Are formed integrally with the connection terminal following the pressure contact switch.
The end of the rod-shaped current detection resistor or the current
The lead terminal of the detection resistor is pinched and connected , and the connection terminal
Is connected to the electronic circuit board including the current detecting section.

FIGS. 1 to 4 show an embodiment of a connection structure of a current detecting resistor according to the present invention. This structure is characterized in that, as shown in FIG. 1, a shunt resistor (current detection resistor) 1 is arranged on a bus bar wiring board (wiring board) 3 side separately from an electronic circuit board 2. is there. A pair of busbars (circuits) 5 and 6 for high current are arranged on the insulating substrate 4 of the busbar wiring board 3 together with other busbars (not shown) on the insulating substrate 4.
As shown in FIG. 2, the press-contact slots 9 of the plate-like terminal portions 7, 8 which are raised from the ends of the bus bars 5, 6 so as to face each other.
It is fixed by pressure to 10. The terminal portions 7 and 8 are provided with pressure contact slots 9 and 10 respectively.

2 are formed to project upward. The rod-shaped shunt resistor 1 is provided on the press contact plate portions 13, 1
4, 15 and 16. Press-fit slot 9,
10 and the press contact plates 13, 14, 15, 16
7, 18 are constituted. As shown in FIG. 1, the electronic circuit board 2 is positioned above the bus bar wiring board 3, and a pair of insertion holes 19 and 20 are formed in the electronic circuit board 2 for the pair of connection terminals 11 and 12. The insertion holes 19 and 20 penetrate the insulating substrate 21, and land portions 24 and 25 of the printed circuits 22 and 23 are formed on the insulating substrate 21 around the insertion holes 19 and 20. Various electronic components 26 are connected to the printed circuits 22 and 23, and the printed circuits 22 and
A current detection element (current detection unit) 27 (FIG. 4) is connected to 23. As shown in FIG. 3, in a state where the electronic circuit board 2 is laminated on the upper side of the bus bar wiring board 3, a pair of connection terminals 11,
Reference numeral 12 passes through the insertion holes 19 and 20 (FIG. 1) and is connected to the printed circuits 22 and 23 of the electronic circuit board 2 by solder 28. A gap 29 is formed between the electronic circuit board 2 and the bus bar wiring board 3. The gap 29 functions as a heat dissipation gap for the large current bus bars 5 and 6 (FIG. 1) and a heat shielding gap for the electronic circuit board 2. Pressing plate 1 of FIG.
It is also possible to support the electronic circuit board 2 by bringing the tips of 3 to 16 into contact with the back surface of the electronic circuit board 2. The electronic circuit board 2 and the bus bar wiring board 3 are electrically connected to each other (not shown).
Housed within. As shown in FIG. 4, a pair of connection terminals 11 and 12 are connected to a current detecting element 27 via printed circuits 22 and 23, and the printed circuits 22 and 23 and the current detecting element 27 are connected.
Is provided on the electronic circuit board 2, and the shunt resistor 1 is provided not on the electronic circuit board 2 but on the bus bar wiring board 3 (FIG. 1) together with the bus bars 5, 6. One bus bar 5 on the input side is connected to the fuse 30. A large current flows from one bus bar 5 to the shunt resistor 1 to the other bus bar 6, and the electric circuit board 2 is not energized. By connecting the voltage drop (voltage analog value) generated by the shunt resistor 1 to the electronic circuit board 2 at the connection terminals 11 and 12 of the bus bars 5 and 6, the current detection element 27 detects the current value. Since a large current does not flow through the electronic circuit board 2, no thermal influence is exerted on the electronic circuit board 2. In addition, heat protection is performed by the bus bars 5 and 6. As a prediction of the effect of the thermal influence, FIG.
The temperature rise at the solder portion of the shunt resistor is about 30 deg, whereas the temperature rise at the tip of the connection terminal 12 on the output side in FIG. 2 of this embodiment is about 20 deg. The conditions are as follows: shunt current is 10 A, resistance is 10 mΩ, power is 2 W, ambient temperature is 25 ° C., and bus bars 5 and 6 in this example are made of brass. FIGS. 5A to 5C show an embodiment of the current detecting resistor. In addition to the shunt resistor 1 shown in FIG.

Also in this case, it goes without saying that the bus bars 5, 6 as a large current circuit are provided on the printed wiring board. As described above, according to the present invention, since the wiring board and the electronic circuit board are connected via the connection terminals, the current detecting resistor is provided not on the electronic circuit board but on the wiring board. As a result, even when a large current is applied to the current detection resistor having a large resistance value, the electronic circuit board is not affected by heat, and the melting of the solder connection portion of the current detection resistor is prevented. You. Also, since a large current does not flow through the electronic circuit board, a large circuit is not required for the electronic circuit board, and the electronic circuit board is reduced in size.
