(Connection part)
Next, the connection part J will be described in detail.
As shown in FIGS. 3 and 4, the connection portion J, which is a portion connecting the case 10 and the connector 20, is provided on the side surface of the case 10.

  Further, in the connection portion J, the case 10 and the connector 20 have an annular raised portion P having a closed shape on one side, and an annular groove portion Q having a closed shape on the other side.

  Further, the connecting portion J is formed with an insertion portion F (details will be described later) in a state in which the protruding portion P is inserted into the groove portion Q, and the gap portion G generated between the protruding portion P and the groove portion Q is The curable amorphous sealing material is cured and sealed by a seal portion S (details will be described later) having a substantially U-shaped cross section.

  In the present embodiment, the raised portion P is formed in the connector 20 so as to surround the terminal portion 22, and the groove portion Q is formed in the case 10 so as to surround the opening portion 12. Thereby, the airtightness around the opening part 12 and the terminal part 22 is securable.

  In this embodiment, the case where the raised portion P is provided in the connector 20 and the groove portion Q is provided in the case 10 is shown. However, the raised portion P may be provided in the case 10 and the groove portion Q may be provided in the connector 20. .

  Then, in a state where the engagement protrusion 10p of the case 10 and the engagement hole 21q provided in the flange portion 21 of the connector 20 are engaged, the male screw portion provided at one end of the fastening member 30 is connected to the engagement protrusion 10p. The flange portion 21 of the connector 20 is attached to the case 10 by the fastening member 30 by being screwed into the provided female screw and supporting the head portion provided at the other end of the fastening member 30 to the flange portion 21 of the connector 20. It is done.

  Accordingly, a structure capable of withstanding the moment acting on the connection portion J between the case 10 and the connector 20 can be obtained, and the pressure acting in the direction in which the case 10 and the connector 20 are separated due to the expansion of the seal portion S due to a temperature change can be counteracted. And airtightness can be secured.

  The position of the raised portion P with respect to the position of the engaging hole 21q and the position of the groove portion Q with respect to the position of the engaging projection 10p are such that the raised portion P and the groove portion Q are in a state where the engaging projection 10p is engaged with the engaging hole 21q. The gap G, in particular, the gap G2 in the direction orthogonal to the ridge direction is formed on both sides of the ridge P.

  Then, the engagement protrusion 10p of the case 10 and the engagement hole 21q provided in the flange portion 21 of the connector 20 are engaged, the flange portion 21 is attached to the case 10 by the fastening member 30, and the connector 20 is attached to the case 10 In the connected state, the positional relationship between the case 10 and the connector 20 is determined, and a gap G2 in a direction orthogonal to the protruding direction is formed on both sides of the protruding portion P based on the positional relationship. Thereby, the cross section of the seal | sticker part S can be made substantially U-shaped, and airtightness can be ensured reliably.

Next, the seal part S and the insertion part F will be described in detail with reference to FIG.
FIG. 5 is a detailed view of the F portion in FIG. 2, and is a cross-sectional view of the insertion portion F between the raised portion P of the connector 20 and the groove portion Q of the case 10.

(Seal part)
As shown in FIG. 5, the gap G generated between the raised portion P of the connector 20 and the groove portion Q of the case 10 is sealed by a seal portion S having a cross section substantially the same shape as the cross section of the gap G. .
The sealing material used as the material of the seal portion S is a curable amorphous sealing material that is cured from a liquid amorphous or viscous material having a fluidity through a predetermined curing condition to become an elastic material. is there. Note that the oil seal and grease seal are excluded from the concept of the curable amorphous sealant.
And since the shape dimension of the seal | sticker part S corresponds to the shape dimension of the gap | interval part G, and it is an elastic body which the curable amorphous sealing material hardened | cured, it closely_contact | adheres and adheres to the whole area of the insertion part F. FIG.
Therefore, even if there is a temperature change, airtightness between the case 10 and the connector 20 can be ensured without causing a gap through which the gas flows in the insertion portion F.

  The curable amorphous sealing material is viscous in an irregular state, and is filled in a gap G formed between the raised portion P of the connector 20 and the groove portion Q of the case 10 in the irregular state. Thus, the seal portion S (see FIG. 5) is cured through predetermined curing conditions and has elasticity. The sealing material preferably has adhesiveness so as to be in close contact with the protruding portion P of the connector 20 and the insertion portion F of the groove portion Q of the case 10 to ensure airtightness.

The curable amorphous sealing material preferably has heat resistance.
The component form of the curable amorphous sealing material may be a one-component form or a two-component form.
The curing mechanism classification of the curable amorphous sealant is not particularly limited, such as moisture curing, dry curing, and mixed reaction curing.

Examples of the curable amorphous sealant include a one-part room temperature curable silicone sealant (cured product durometer A hardness: A28, cured product tensile strength: 2.5 MPa, cured product elongation: 500%). Can be used.
In addition, each numerical value of said physical property is a representative value based on the measured value assumed to be normal distribution.

The durometer A hardness of the seal portion S, which is a cured product of the sealing material, is A20 to A45, preferably A22 to A41, and more preferably A25 to A41.
The tensile strength of the seal portion S, which is a cured product of the sealing material, is 5.0 MPa or less, preferably 0.15 MPa to 5.0 MPa, and more preferably 2.0 MPa to 5.0 MPa.
The elongation percentage of the seal portion S, which is a cured product of the sealing material, is 200% to 1800%, preferably 250% to 530%, and more preferably 270% to 510%.

  Since the sealing material is a curable amorphous sealing material, the sealing portion S is filled in the groove portion Q in an amorphous state and bonded so as to conform to the surface of the groove portion Q, and the sealing portion S after the sealing material is cured is used as the groove portion Q. It is made to adhere to.

  Further, when the raised portion P is inserted into the groove portion Q filled with the sealing material in an irregular shape, the seal portion S is bonded to the surface of the raised portion P so that the seal material is cured, and the raised portion is used as the raised portion. It is made to adhere to P. Since the cured seal portion S has a predetermined hardness, tensile strength, and elongation rate, the size of the gap G between the case 10 and the connector 20 changes even when the temperature changes to high or low temperatures. It can follow and elastically deform, ensuring airtightness.

  Further, if the sealing material has a high heat resistance such as the above silicone sealing agent, the thermal expansion coefficient between the seal portion S and the case 10 and the connector 20 is high even at a high temperature (for example, 150 ° C.). It is possible to elastically deform following the change in the size of the gap G caused by the difference between them, and to ensure airtightness for a long time (for example, 500 to 1000 hours).

(Insertion part)
As shown in FIG. 5, the dimension (height dimension) in the protruding direction (the arrow direction in FIG. 5) of the protruding part P of the connector 20 is smaller than the dimension (depth dimension) in the protruding direction of the groove portion Q of the case 10. . Thereby, in the state where the raised portion P of the connector 20 is inserted into the groove portion Q of the case 10, a gap G1 in the raised direction in the cross-sectional dimension of the gap portion G between the raised portion P and the groove portion Q is secured, and the sealing material is sealed in the gap G1. The seal part S can be reliably interposed, and airtightness can be secured.

  Even if the raised portion P of the connector 20 expands in the raised direction due to thermal expansion, the gap G1 is secured, so that the raised portion P of the connector 20 and the groove portion Q of the case 10 come into contact and repel each other. In addition, a force for separating the case 10 and the connector 20 does not act.

Further, as for the cross-sectional dimension of the gap G between the raised portion P and the groove Q, the size g1 of the gap G1 in the raised direction of the raised portion P is larger than the size g2 of the gap G2 in the direction perpendicular to the raised direction.
Here, when the periphery of the motor 1 becomes high temperature, the connector 20 expands due to the fact that the thermal expansion coefficient of the resin connector 20 is relatively larger than the thermal expansion coefficient of the metal case 10. The bulge P is deformed in the bulge direction, the dimension g1 of the gap G1 is reduced, and a part of the seal portion S made of the sealing material in the gap G1 is pushed away by the bulge P, thereby maintaining elasticity. While moving, it moves to the gap G2. At this time, stress acts on the seal portion S, and the degree of adhesion to the raised portion P of the connector 20 and the groove portion Q of the case 10 is increased, so that airtightness is improved.

Further, when the temperature around the motor 1 is restored and the expansion of the connector 20 is restored, the raised portion P is deformed in the direction opposite to the raised direction, the dimension g1 of the gap G1 is restored to the original, and the gap G2 is restored. A part of the seal portion S made of the pushed-off sealing material moves to the gap G1 while being deformed by its elasticity, and returns to its original state.
Therefore, according to such a cross-sectional dimension of the gap portion G, the seal portion S can always be present in the gap G2, and airtightness can be ensured.

  In addition, even when the motor 1 is disposed in the engine room of the vehicle, for example, the airtightness between the case 10 and the connector 20 can be maintained even when the surroundings of the motor 1 are at a high temperature (for example, 150 ° C.). Even if the temperature changes repeatedly, a part of the seal part S existing in the gap G1 and a part of the seal part S existing in the gap G2 cooperate to maintain airtightness.

  Since the seal portion S is molded near the lower limit of the operating temperature of the motor 1, stress is always applied to the seal portion S in the range from the lower limit to the upper limit of the operating temperature. The repulsive force from S to the insertion part F is maintained, and airtightness is maintained.

(Connection procedure)
Hereinafter, a procedure for connecting the connector 20 to the case 10 will be mainly described.

(1) The sealing material is filled in the groove portion Q provided in the case 10 without any gap, and the groove portion Q and the sealing material are adhered and adhered.
(2) Next, before the sealing material is completely cured, the engagement protrusion 10p provided in the case 10 is engaged with the engagement hole 21q provided in the flange portion 21 of the connector 20. At the same time, the raised portion P of the connector 20 is inserted into the groove portion Q filled with the sealing material, and the sealing material and the raised portion P are adhered and adhered. When the raised portion P is inserted into the groove portion Q, the sealing material and the raised portion P are in close contact with each other, while the sealing material filled in the groove portion Q is a gap portion between the raised portion P and the groove portion Q. G overflows between the surrounding case 10 and the connector 20, but as a result, the insertion portion F and the seal portion S are in close contact with each other, the bending portion in the cross section of the seal portion S is increased, and the seal is sealed. Since the contact area between the part S and the case 10 and the connector 20 increases, the airtightness is further improved.
(3) The fastening member 30 is screwed into a female screw provided on the engagement protrusion 10p of the case 10, and the case 10 and the connector 20 are fastened.
(4) The sealing material is hardened due to the change over time, and the seal portion S is formed between the raised portion P and the groove portion Q.
In this way, the connector 20 can be easily installed with respect to the case 10 while ensuring airtightness.
After connecting the connector 20 to the case 10, the terminal portion 22 provided on the connector 20 is connected to the substrate 200, and then the procedure of attaching the case cover 300 and attaching the motor main body 100 is continued. The motor 1 may be assembled.

  The preferred embodiment of the present invention has been described in detail above. However, the motor according to the present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the gist of the present invention described in the claims. Can be modified and changed.

For example, in the above-described embodiment, one of the case 10 and the connector 20 has been described as having a single annular raised portion P. However, the present invention is not limited to this. Thereby, airtightness can be ensured more reliably.
Similarly, in the above-described embodiment, one of the case 10 and the connector 20 has been described as including a single annular groove portion Q. However, the present invention is not limited thereto, and the annular groove portion Q may be provided more than double. Thereby, airtightness can be ensured more reliably.

  According to the motor of the present invention, a motor main body having a rotor and a stator, a connector, a board that electrically connects the motor main body and the connector, and a case that accommodates the board and is attached to the connector are provided. The case and the connector have a ridge with a closed shape on one side, a groove with a closed shape on the other, the ridge is inserted into the groove, and is formed between the ridge and the groove. Since the gap portion is sealed by a seal portion having a cross section substantially the same shape as the cross section of the gap portion, even if the size of the gap portion changes due to the difference in thermal expansion coefficient between the case and the connector. Since the seal portion by the sealing material is elastically deformed in the gap portion and follows the change in the size of the gap portion while being in close contact with the insertion portion, airtightness can be ensured. Therefore, since the liquid can be prevented from entering the case, the components inside the case can be protected. In addition, since gas can be prevented from entering the case, corrosion of the circuit board and the like inside the case can be prevented.

  According to the motor of the present invention, since the seal portion is an elastic body obtained by curing the curable amorphous sealing material, the seal portion can be closely adhered to the insertion portion and bonded to the size of the gap portion. And airtightness can be secured.

  Since the seal part is an elastic body, even if the size of the gap changes due to the difference in thermal expansion coefficient between the case and the connector, the seal part made of the sealing material is elastically deformed in the gap. Since it follows the change in the size of the gap portion while keeping in close contact with the insertion portion, airtightness can be ensured.

  Since the sealing part is not a standard sealing material like an O-ring, it is not necessary to adjust the dimensional relationship between the O-ring and the insertion part with high precision. It is possible to match the cross-sectional shape of the gap part and the seal part in the insertion part without requiring high precision in the processing dimensions of the raised part and the groove part to improve the mutual contact area and adhesion, ensuring airtightness it can.

  According to the motor of the present invention, the case is made of metal and the connector is made of resin. Therefore, particularly at high temperatures, the case and the connector have different coefficients of thermal expansion. The gap size is reduced, and the seal portion expands. Therefore, stress acts on the seal portion, and the support pressure from the seal portion to the insertion portion increases, and the airtightness at high temperature increases.

  According to the motor of the present invention, the connector has a terminal portion, the case has an opening through which the terminal portion passes, the raised portion is formed in the connector so as to surround the terminal portion, and the groove portion surrounds the opening. Since it is formed in a case, the airtightness around a terminal part and an opening part can be ensured reliably.

  According to the motor of the present invention, the cross-sectional dimension of the gap portion is larger than the gap size in the direction perpendicular to the ridge direction of the bulge portion. A seal part can be reliably interposed, and airtightness can be secured.

  According to the motor of the present invention, the connector has a flange, and the flange is attached to the case via the fastening member. Therefore, the structure can withstand the moment acting on the connection portion between the case and the connector, and at a high temperature. It can counteract the pressure acting in the direction separating the case and the connector, which is caused by the expansion of the seal portion, and can ensure airtightness.
