Problems solved by technology

However, since recent electronic control devices have been miniaturized, the shape of the connector terminal assembly 30 has also been miniaturized, and since the number of connector main bodies 32 has increased, the flow of the sealant 37 is likely to be hindered.
Therefore, even if the sealant 37 is injected from the injection nozzle 36, the sealant 37 does not flow as a whole and does not spread, resulting in poor sealing.
[0009] Therefore, although a low-viscosity sealant 37 is selected, (1) applying pressure to the sealant 37 after injection, (2) injecting the sealant 37 from a plurality of injection nozzles 36 , (3) increasing the injection pressure of the sealant 37 However, due to the increase in the number of connector main bodies 32 and the miniaturization of the shape of the base body 31 as described above, the sealant 37 cannot be stably flowed and diffused.

Embodiment 1

[0082] In order to cope with the above-mentioned poor sealing, the present embodiment proposes the following structure. That is, the bottom wall formed on the base of the connector terminal assembly is formed as an inclined surface, and the sealing material is injected so that the sealing material flows down due to gravity. Thereby, the sealant can be stably diffused and filled into the inner space of the base body by a simple method, so that the space between the base body and the connector main body can be reliably sealed.

[0083] Figure 4A The illustrated connector terminal portion represents a connector terminal portion 30B that transmits a detection signal from a sensor to the electronic control assembly. In the connector terminal part 30B, the base body 31B is composed of an inclined bottom wall 38 and a side wall 34 to form an internal space 35. The inclined bottom wall 38 is composed of an inclined surface inclined relative to the horizontal state, and the side wall...

Embodiment 2

[0091] Next, other embodiments of the present invention will be described. In this embodiment, the bottom wall formed on the base of the connector terminal assembly is formed of two inclined surfaces that incline downward and intersect, and the sealing material is injected so that the sealing material falls by gravity. Therefore, the sealant can be stably diffused and filled into the inner space of the base body by a simple method, and thus the space between the base body and the connector main body can be reliably sealed.

[0092] Figure 5A The illustrated terminal portion represents the connector terminal portion 30B of the connector terminal assembly 30 . In the connector terminal portion 30B, the base body 31B is composed of an inclined bottom wall 39 and a side wall 34 to form an internal space 35 . It stands vertically from the entire circumference of the inclined bottom wall 39 . The intersection position of the two inclined surfaces is near the approximate center o...

Abstract

The present invention provides a connector terminal assembly, an electronic control unit, and an electric power steering unit. The electronic control unit t has a novel connector terminal assembly capable of stabilizing and diffusing a sealant. The bottom wall of the base body formed on the connector terminal assembly is formed as an inclined surface so that the sealant is injected into the sealing material by gravity flow. Therefore, it is possible to stabilize the sealant by a simple method and to diffuse and fill the inside space of the substrate, and to securely seal the space between the substrate and the connector main body.

Description

technical field [0001] The present invention relates to a connector terminal assembly connected to a power line and a signal line, an electronic control device using the connector terminal assembly, and an electric power steering device using the electronic control device. Background technique [0002] In order to electronically control control devices and control systems of various industrial machines, a power supply, control device, or detection sensor is usually electrically connected to an electronic control device via a cable. For example, in an electric power steering device of a motor vehicle, the rotational direction and rotational torque of a steering shaft rotated by an operator operating a steering wheel are detected, and an electric motor is driven based on the detected value so that it rotates in the same direction as the steering shaft. Rotate in the same direction, which creates steering assist torque. In order to control this electric motor, an electronic co...
