Problems solved by technology

This connector also vibrates the wiring harness with greater vibration than the case where the electronic control unit is mounted on the vehicle body frame side, so the vibration influence is further increased

no. 1 approach

[0034] First, use Figure 1 ~ Figure 3 The configuration of the electronic control device 1 will be described. figure 1 It is a perspective view of the electronic control device 1 according to the first embodiment of the present invention. figure 2 Yes figure 1 A cross-sectional view of the electronic control unit 1 is shown. image 3 Yes figure 2 An enlarged sectional view of a main part (part A) of the electronic control unit 1 shown.

[0035] In this embodiment, in particular, an ATCU (Automatic Transmission Control Unit) as an electronic control unit installed in an engine room will be described.

[0036] like figure 2 As shown, the electronic control device 1 includes: a substrate 6 on which a first connector 22 connected to the vehicle transmission 2, a second connector 32 connected to the connector 31 of the vehicle wiring harness 3, and a plurality of electronic components 8 are installed; The base 4 and the cover 5 on which the first and second connectors 22 ...

no. 2 approach

[0063] Figure 4 It is an enlarged cross-sectional view of a main part (part A) of the electronic control device 1 according to the second embodiment of the present invention.

[0064] In this embodiment, a metal terminal 223 (a metal pin (column portion)) is provided on the first connector 22 instead of image 3 The resin pin 222 shown in. The metal terminal 223 is inserted into the concave portion 41 filled with the damping member 71 .

[0065] In this structure, the metal pin 223 is engaged with one side of the base 4, so a ratio of image 3 The resin pins 222 shown in are more securely fixed. In addition, even if the pin diameter is smaller than that of the resin pin 222, the same effect can be obtained, so the mounting area can also be reduced in size.

[0066] As described above, according to the present embodiment, assembly is easy, and the influence of vibration and external force applied from the connector can be reduced.

no. 3 approach

[0068] Figure 5 It is an enlarged cross-sectional view of a main part (part A) of the electronic control device 1 according to the third embodiment of the present invention.

[0069] In this embodiment, a screw 225 (column part) is used instead of image 3 The resin pin 222 shown in. Screws 225 are used to fix the first connecting member 22 on the base plate 6 .

[0070] The heads of the screws 225 protruding toward the back surface of the base plate 6 are engaged with the damping members 71 in the recesses 41 provided in the base 4 . Thereby, the same effect can be acquired.

[0071] In this structure, since it can be fixed at a position closer to the substrate 6, the vibration damping effect is also increased. In addition, the heads of the screws 225 are located on the surface F1 of the substrate 6 .

[0072] In addition, the screws 225 used in this structure are self-tapping screws, and are directly screwed to the first connector housing 224 made of resin. Accordingl...

Abstract

Provided is an electronic control device that is easily assembled and with which it is possible to reduce the effects of vibration and external force applied from a connector. Electronic components 8 are installed on a substrate 6. A base 4 covers a surface F1 of the substrate 6. A cover 5 covers a surface F2 of the substrate 6. A first connector 22, which is installed on the surface F2, connects to a connector 21 fixed to an on-board transmission 2. A second connector 32, which is installed on the surface F2, connects to a connector 31 of a harness 3. First vibration-suppressing parts 41, 71, which are provided to the inside surface of the base 4 facing the end surface of the first connector 22 on the surface F2 side, suppress the vibration of the first connector 22.

Description

technical field [0001] The invention relates to electronic control devices. Background technique [0002] In recent years, in automobiles, the space inside the engine room has been reduced in size and narrowness due to the securing of the space inside the vehicle compartment and the increase in the number of components in the engine room. In addition, the cost reduction of vehicles is also progressing year by year. Therefore, in a method of mounting an electronic control device, a structure capable of being mounted in a small space at a lower cost is required. [0003] For example, conventionally, an electronic control device for controlling an on-vehicle transmission is mounted on the vehicle body frame side in the engine room, and is connected to the on-vehicle transmission and other on-vehicle control devices through a wire harness. In recent years, however, there has been a demand for structures that reduce the wiring harness between the vehicle-mounted transmission an...
