Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pump mounting device, particularly a pump mounting device for a wash tank installed in an automobile.

As shown in FIGS. 1 to 3, a conventional pump mounting device for a wash tank of this type has a square hole 1-1 for mounting the pump in a flange 1 formed integrally with the wash tank. On the other hand, the pump 2 is provided with a pair of mounting hooks 2-1 that engage with the mouth edge of the square hole 1-1, and both of the hooks 2-1
A power supply terminal 3 is provided protrudingly between them. When installing this pump 2 to the flange 1, connect both mounting hooks 2-1 to the square holes.
-1, and then insert the connector 4 inserted between the two mounting hooks 2-1 from the back side of the flange 1, connect the connector 4 to the power supply terminal 3, and connect the connector 4 to the power supply terminal 3. By inserting the connector 4, the engagement between the mounting hook 2-1 and the edge of the square hole is maintained. However, in such a structure, there is no locking means to maintain the fitted state of the connector 4, so the connector 4 may come off unexpectedly, and there is no sense of moderation when inserting the connector, so the connector is There were drawbacks such as not being able to feel whether or not it was completely inserted. Furthermore, square hole 1 of flange 1
-1 increases in vertical dimension, hook 2-
If the height of the flange 1 is too low to fit into the square hole 1-1, or if the thickness of the flange 1 becomes thicker than a predetermined dimension, it becomes impossible to engage the hook 2-1. However, there were problems such as the need to accurately set the dimensions of the flange 1.

The present invention has been made in response to these conventional problems, and has as its object to provide a pump mounting device which has a connector that is attached to the side of the pump and engages into a locking hole provided in the tank, and which is equipped with a locking structure which locks the connector into the locking hole in the tank wall in the up, down, left and right directions, and a pressing structure which elastically presses the connector against the tank wall, thereby enabling the engagement between the tank and the pump to be securely engaged without any play.

The present invention will be explained in detail below based on the embodiments shown in FIGS. 4 and 7. Reference numeral 10 denotes a pump, and a connector 11 is integrally fixed to the side surface of the pump 10, so that the pump 10 can be attached to a pump mounting plate 12 formed integrally with a tank (not shown) via the connector 11. It's summery.
The connector 11 has a terminal 13 connected to the motor inside the pump 10 inside the connector 11, and a pair of left and right projections 14 projecting in the left and right direction on the outer upper surface of the connector 11. Gap a slightly larger than the wall thickness of the mounting plate 12
The shoulder portion 15 is formed to maintain the same. This shoulder part 1
5 is formed with an elastic arm 16 extending downward and acting elastically in the direction of the gap, and a claw piece 17 is formed at the tip of the elastic arm 16. Numeral 18 is a protrusion provided on the lower surface of the connector 11, and a protrusion 19 is formed opposite to the protrusion 18 to maintain a gap a. Note 2
0 is the suction port of the pump 10, and 21 is its discharge port. The pump mounting plate 12 is formed with a through hole 22 into which the connector 11 can be inserted.
A T-shaped notch 23 is formed at the upper left and right sides of the through hole 22 through which the projection 14 can pass. Further, on the front surface of the mounting plate 12, an engaging protrusion 24 to which the claw piece 17 is engaged is formed. 25 indicates a male connector inserted into the connector 11.

The above is the configuration of this embodiment. Next, the operation will be described. The pump 10 is mounted on the pump mounting plate 1.
2, insert the connector 11 attached to the pump 10 into the through hole 22 of the mounting plate 12, and then pass the protrusion 14 through the notch 23 and the protrusion 18 through the through hole 22. After the connector 11 is pressed down, the gap a formed above and below the connector 11 is
A through hole 22 formed in the pump mounting plate 12
At the same time, the mouth edge of the connector 11 is fitted and the claw piece 17 is locked to the engagement protrusion 24, and the connector 11 is attached to the pump mounting plate 1.
It is fixed without being pulled up against 2.
Therefore, the connector 11 includes the protrusion 14 and the protrusion 18.
and the pump mounting plate 12 by engagement with the pump mounting plate 12.
The connector 11 does not come off in the thickness direction, and is fixed in the vertical direction by the engagement between the claw piece 17 and the engagement protrusion 24, and furthermore by the engagement between both side surfaces of the connector 11 and the side edges of the through hole 22. In this way, the connector 11 is locked and held to the pump mounting plate 12 vertically, horizontally, and frontward and rearward. Furthermore, since the connector itself 11 is biased in the direction of being pulled out from the pump mounting plate 12 by the elastic action of the pair of elastic arms 16, there is no play between the connector 11 and the pump mounting plate 12. It has the effect of being able to maintain the fit.

As described above, in the present invention, the terminal 13 for electrical connection is provided upright on the pump 10, and the connector 11 in the shape of a rectangular tube is provided surrounding the terminal 13. A protrusion 14 is provided on the upper part of the arm 16, and an engaging claw 17 is provided on the inner side at a distance from the protrusion 14, and the upper end of the arm 16 is fixed to the lower end of the arm 16. A T-shaped through hole 22 having a notch 23 through which the protrusion 14 can pass and into which the connector 11 is inserted is provided, and the engaging claw 17 is engaged with the insertion side surface of the pump 10. The connector 11 is inserted into the through hole 22 so that the protrusion 14 passes through the notch 23, and the front protrusion 18 and the protrusion 14 are placed on the side opposite to the insertion side. After protruding, the pump 10 is lowered and the engaging claw 17 is moved to the engaging step portion 2.
4, the connector 11 integrated with the pump 10 can be easily and reliably attached to the mounting plate 12. Furthermore, even if there is some dimensional error, that is, a gap, between the connector 11 and the through hole 22 for inserting the connector, the elastic action of the arm 16 will press the space between the connector 11 and the mounting plate 12. Since the connector 11 is attached to the mounting plate 12
The pump mounting device can be engaged with and held without any looseness, and therefore can be securely fixed even with low dimensional accuracy, which has the effect of providing a highly economical pump mounting device.
