BACKGROUND OF THE INVENTION 
The present invention relates to a circuit body to which electric parts are 
directly connected. 
Related Art 
FIG. 2 is a view showing A/T unit 1. In a main body 2 of this unit 1, there 
are provided a plurality of electric parts (shown in FIG. 5) 3 such as a 
solenoid valve which is an electromagnetic valve for turning on and off a 
hydraulic circuit. Electric parts 3 are directly connected to a circuit 
body (shown in FIG. 4) 4 arranged in the primary body 5. The circuit body 
4 includes: a primary body 5 of the circuit body having an inner circuit 
30; a plurality of connector blocks 6 to which the electric parts 3 are 
directly connected; and a cover (shown in FIG. 3) 31 for closing a 
backside of the main body 5 of the circuit body. 
As shown in FIGS. 3 and 4, the inner circuit 30 is composed of electric 
wires 32, 34 arranged in the primary body 5 of the circuit body, and 
terminals 33. Each terminal 33 is composed of a contact section 33a 
accommodated in a terminal accommodating chamber 35 of the connector block 
6, and a crimp section 33b to which the electric wires 32, 34 are crimped. 
The terminal 33 is directly connected to a contact section 33a arranged in 
the connector block 6, and also connected to a terminal section 3a of the 
electric part 3. 
As shown in FIG. 5(a), the circuit body 4 to which the electric parts 3 
such as a solenoid valve are directly connected is fixed to the main body 
2 of the unit 1 by screws 7. When the electric parts 3 are directly 
engaged with the connector block 6, they are connected to the inner 
circuit of the circuit body 4, so that they can be connected to an 
electric power source arranged outside via the wire harness 8 which is 
drown out from the inner circuit. 
However, when errors are caused in the process of assembling the electric 
parts 3 to the main body 2 of the unit 1, the terminals 3a connected to 
the connector block 6 deviate from predetermined positions. Accordingly, 
there is caused a positional deviation between the terminals 3a connected 
to the connector block 6 and the terminals of a bus bar arranged in the 
connector block 6. Therefore, the contact sections 33a of the terminals 33 
are pushed by the terminals 3a of the electric parts 3. As a result, the 
reliability of contact points is deteriorated. 
SUMMAY OF THE INVENTION 
It is an object of the present invention to provide a circuit body in which 
the positional deviation of electric parts is absorbed and the reliability 
of contact can be enhanced. 
In order to accomplish the above object, the present invention provides a 
circuit body comprising: a main circuit body having an inner circuit; a 
plurality of connector blocks integrally supported by the main circuit 
body and directly connected to electric parts; and flexible legs for 
supporting the plurality of connector blocks independently from the main 
circuit body so that they can be freely moved in the direction 
perpendicular to the connecting direction of the electric parts. 
When electric parts are directly connected to the connector block in this 
circuit body, the connector block can be freely moved in the direction 
perpendicular to the connecting direction. Therefore, it is possible to 
absorb the positional deviation of the electric parts. As a result, it is 
possible to connect the connector block to the electric parts in a good 
condition. 
The present invention provides a circuit body, the inner circuit including: 
a plurality of terminals having a crimp section accommodated in each 
connector block, the crimp section being crimped to a contact section of 
an opponent terminal and also crimped to an electric wire; and electric 
wires arranged in predetermined paths. 
In this circuit body, the inner circuit is composed of electric wires 
arranged in predetermined paths, and the electric wires are connected to 
terminals.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
An embodiment of the circuit body of the present invention will be 
explained below. FIG. 1(a) is a view showing a circuit body 10, and FIG. 
1(b) is a plan view showing the circuit body 10, wherein a portion of the 
circuit body 10 is shown being enlarged in the view. 
As shown in FIG. 1(a), the circuit body 10 includes: a primary housing 12 
of the circuit body, the essential structure of which is the same as that 
of the circuit body 30 shown in FIG. 4, and only the wiring path of the 
inner circuit of which is different from that of the circuit body 30; and 
two connector blocks 13, 14 integrally supported by the primary housing 12 
of this circuit body, directly connected to the electric parts shown in 
FIG. 5. The primary housing 12 of the circuit body includes: a secondary 
housing 15 in which the two connector blocks 13, 14 are integrally formed; 
and a cover 16 for closing the lower side of the secondary housing 15. 
The secondary housing 15 includes: a drawing section 18 integrally made of 
synthetic resin, from which the wire harness 17 connected to the inner 
circuit is drawn out; and a connecting section 19, the width of which is 
larger than that of the drawing section 18. The connector blocks 13, 14 
are independently supported by the connecting section 19 so that the 
connector blocks 13, 14 can be freely moved in a direction parallel (i.e., 
lateral direction) to a plane corresponding to the surface of the 
connecting section 19, that is, the connector blocks 13, 14 can be freely 
moved in a direction perpendicular to the connecting direction of the 
electric parts. 
As shown in FIG. 1(b), in the connecting section 19, there are formed 
rectangular through-holes 20, 20 which are larger by a size than the 
connector blocks 13, 14. Four flexible legs 21a, 21b, 21c, 21d are 
respectively protruded from centers of the four inner walls 20a, 20b, 20c, 
20d of these through-holes 20. The four flexible legs 21a, 21b, 21c, 21d 
are integrally connected to the lower portions of the four outer 
circumferential surfaces 13a, 13b, 13c, 13d of the connector block 13 
arranged at the substantial center of the through-hole 20. Due to the 
above arrangement, the connector block 13 can be freely moved in any 
direction (lateral directions indicated by arrows in FIG. 1(b)) parallel 
to the plane corresponding to the surface of the connecting section 19. In 
the same manner, the connector block 14 is movably supported by the 
flexible legs 21a, 21b, 21c, 21d with respect to the connecting section 
19. 
Each connector block 13, 14 is otherwise similar to the connector blocks 
discussed above with reference to FIG. 3(a). Specifically, inside of each 
connector block 13, 14, there are formed two terminal accommodating 
chambers 35, 35. In each of these terminal accommodating chambers 35, 35, 
there is provided a contact section 33a of the terminal 33 as discussed 
above and shown in FIG. 3 as well as a crimp section 33b. 
The cover 16 is composed of a closing section 27 for closing the lower side 
of the secondary housing 15, and a plurality of engaging frames 28. The 
engaging frames 28 engage with a plurality of engaging protrusions 29 
protruding from the side end section of the secondary housing 15. In this 
way, the cover 16 is held by the secondary housing 15 via the engaging 
frames 28. 
In this embodiment, even if the electric parts 3 deviate from predetermined 
positions when they are directly connected to the connector blocks 13, 14, 
since the connector blocks 13, 14 can be freely and independently moved in 
any direction with respect to the connecting direction, positional 
deviation of the electric parts can be absorbed. 
It is possible to absorb the positional deviation of the electric parts as 
described above. Therefore, the reliability of connection can be enhanced. 
Since the plurality of connector blocks 13, 14 can be simultaneously 
connected to the electric parts, it is possible to prevent the connector 
from being disconnected. 
Since positional deviation of the electric parts can be absorbed, it is 
advantageous when the assembling work is automatized. 
Compared with an assembling work in which the electric parts are directly 
connected to the connector block while the positions of the electric parts 
are being adjusted, this embodiment is advantageous because positional 
deviation of the electric parts can be absorbed. Therefore, the attaching 
and detaching work can be made easy and the maintenance can be easily 
carried out. 
In the circuit body of this embodiment, the connector block 13, 14 can be 
respectively and independently moved. Therefore, even if positions of the 
electric parts connected to the connector blocks 13, 14 deviate 
differently from each other, the positional deviation of these electric 
parts can be respectively absorbed. 
As explained above, according to the present invention, the connector 
blocks can be freely moved in a direction perpendicular to the connecting 
direction. Accordingly, it is possible to absorb positional deviation of 
the electric parts. As a result, the connector block and the electric 
parts can be connected in a good condition. 
According to the present invention, the inner circuit is composed of 
electric wires arranged in predetermined paths, and the electric wires are 
connected by the terminals. Therefore, wiring can be easily conducted, and 
the manufacturing cost can be reduced.
