Description

  The present invention relates to a hydraulic pressure control device including a solenoid valve that opens and closes a fluid passage and a substrate on which electronic components are arranged, and is particularly suitable for a hydraulic pressure control device of a vehicle brake device.

  As shown in FIG. 48, in a conventional hydraulic control device for a vehicle brake device, an electromagnetic valve 2 that opens and closes a fluid passage is mounted on a body 1 in which a fluid passage through which brake fluid flows is formed. In the resin case 3, the solenoid housing portion 32 and the connector housing portion 33 are connected by the connecting portion 1 </ b> A, and the solenoid 21 of the electromagnetic valve 2 is housed in the solenoid chamber 2 </ b> A in the solenoid housing portion 32.

The substrate chamber 4A and the solenoid chamber 2A are separated by a partition wall 5A of the case 3. The substrate 5 is accommodated in the substrate chamber 4 </ b> A, and the substrate 5 is held by the substrate holding part 6 </ b> A of the case 3.

(Eighth embodiment)
An eighth embodiment of the present invention will be described. 15 is a cross-sectional view of the main part of the hydraulic control device according to the eighth embodiment, FIG. 16 is a cross-sectional view taken along the line GG in FIG. 15, and FIG. 17 is a cross-sectional view taken along the line H-H in FIG. 18 is a cross-sectional view taken along the line II of FIG.

  In the present embodiment, the coupling method of the solenoid 21 and the substrate 5 in the first embodiment is changed. The same or equivalent parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In the present embodiment, as shown in FIGS. 15 to 18, the first stay 252 in the hydraulic control device of the first embodiment is eliminated. The substrate 5 is integrally supported and fixed to the solenoid 21 by the solenoid terminal 22. Thus, by eliminating the first stay 252, the substrate 5 can be fixed to the solenoid 21 with a simpler configuration.

  The solenoid terminal 22 of the first embodiment is provided with a clinching portion that is bent in a crank shape in order to facilitate its elastic deformation, but the solenoid terminal 22 of the present embodiment eliminates the clinching portion. In other words, the solenoid terminal 22 of this embodiment is linear.

  Specifically, the support column 8 of this embodiment is made of a material (for example, brass) such that expansion and contraction of the support column 8 due to heat is equivalent to expansion and contraction of the solenoid 21 and the solenoid terminal 22. Thereby, the relative displacement between the solenoid terminal 22 and the substrate 5 at the time of thermal load is reduced, and the clinching part is not required.

  Since the clearance between the electromagnetic valve 2 and the substrate 5 can be reduced by eliminating the clinching portion in this way, the hydraulic pressure control device is further combined with the elimination of the conventional partition wall and cover. It can be made small.

  Moreover, the support | pillar 8 and the hole (not shown) of the board | substrate 5 are made into the clearance fit. Thereby, if the expansion amount of the solenoid 21 and the solenoid terminal 22 at the time of heat load becomes larger than the expansion amount of the support column 8, the support column 8 and the substrate 5 can be easily displaced relatively. Generation of stress at the joint between the terminal 22 and the substrate 5 can be suppressed.

  In the configuration of this embodiment, a stress is generated at the joint between the solenoid terminal 22 and the substrate 5 when vibration is generated. This stress is compared with the stress generated at the joint due to the difference in thermal expansion coefficient. Intermittent and small.

  In the present embodiment, the coupling method of the solenoid 21 and the substrate 5 in the second embodiment is changed. The same or equivalent parts as those of the second embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In this embodiment, as shown in FIGS. 19-21, the 1st stay 252 in the hydraulic-pressure control apparatus of 2nd Embodiment is abolished. The solenoid 21 is integrally supported and fixed to the substrate 5 by the solenoid terminal 22. Thus, by eliminating the first stay 252, the solenoid 21 can be fixed to the substrate 5 with a simpler configuration.

  Further, since the solenoid 21 is not fixed to the body 1 and the solenoid 21 is suspended only by the solenoid terminal 22 on the substrate 5, no relative displacement occurs between the solenoid terminal 22 and the substrate 5 at the time of thermal load. Accordingly, the clinching portion of the solenoid terminal 22 is not necessary, and the distance between the solenoid valve 2 and the substrate 5 can be reduced. Therefore, in combination with the abolition of the conventional partition wall and cover, the hydraulic pressure control device Can be further reduced in size.

  In the configuration of this embodiment, a stress is generated at the joint between the solenoid terminal 22 and the substrate 5 when vibration is generated. This stress is compared with the stress generated at the joint due to the difference in thermal expansion coefficient. Intermittent and small.
