Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector fixing device for an evaporator, which can be implemented when fixing a connector of a sensor for detecting a temperature in an evaporator case in an air control device for a vehicle.

[0002]

[Prior Art]

 A sensor (generally a thermistor) is installed in the evaporator used for the air control device of the automobile, and it detects the temperature inside the evaporator case. FIG. 9 shows an example thereof, in which the temperature of the refrigerant in the vicinity of the blowout portion 2 of the evaporator case 1 is detected by a sensor (not shown), and this detection signal is coupled to the sensor side connector 3 and this sensor side connector 3. It is output to a control unit (not shown) via an external connector on the evaporator (not shown), etc., and the control unit controls to prevent frost and freezing.

In this case, the sensor-side connector 3 is provided with a claw 5 which can be fitted into a hole 4 formed in the evaporator case 1 as shown in FIG. 10, and the claw 5 is fitted into the hole 4. It is fixed to the evaporator case 1 by means of binding, as shown in FIG. 11, by a band 6 (band clamp), or by attaching a harness cover 7 as shown in FIG. The device for connecting the connector of the wire harness used for the instrument panel is described in Japanese Utility Model Publication No. 1-142345, and an example of the wiring structure for connecting the wiring connector on the wiring harness side to the wiring connector on the instrument side is It is disclosed in Japanese Patent Laid-Open No. 61-18965.

[0004]

[Problems to be solved by the device]

 By the way, it is desired that the sensor side connector 3 of the evaporator be easily attached, and that the structure is simple and inexpensive. However, in the structure shown in FIG. 10, the sensor-side connector 3 is provided with the claws 5, and the cost is increased accordingly, so that the above-mentioned demand cannot be met, and it is possible to swing it easily and securely. Since it cannot be fixed and further cannot be securely fixed in this way, there is a problem in that connection requires skill. In addition, in the case shown in FIGS. 11 and 12, it is necessary to prepare the band 6 and the harness cover 7, and accordingly, the number of parts is increased, and the increase in the number of parts increases the number of assembling steps, resulting in an increase in cost. In addition to not being able to meet the above-mentioned demands, there is a possibility that an abnormal noise may be generated when it cannot be securely fixed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a connector fixing device for an evaporator that can be easily attached and has a simple structure.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention integrally forms a pair of plate-shaped parts, which are arranged at a predetermined distance so as to sandwich a part of the connector, in an evaporator case. It is characterized in that a claw portion is formed at a position higher than the height of the connector so as to project toward opposite sides.

[0007]

[Action]

 With such a configuration, when the pair of plate-shaped portions are pressed by a part of the connector, the pair of plate-shaped portions are bent outward and the part of the connector is easily inserted between the pair of plate-shaped portions, and When a part of the connector passes through the claw part, the pair of plate-shaped parts returns to the original state and the claw part presses a part of the connector from the upper side.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. In the figure, the sensor side connector 3 is formed by joining a substantially rectangular cord insertion portion 9 for connecting a cord 8 for an evaporator sensor (not shown) and a substantially rectangular tubular connecting portion 10 for connecting to an evaporator external side connector (not shown). The structure is such that the connecting portion 10 is larger than the cord inserting portion 9, and a step is formed on the lower surface portion of each.

In addition, a substantially plate-shaped connector fixing portion 12 having a plate-shaped portion 11 described later is integrally fixed to the vicinity of the blowout portion 2 of the evaporator case 1 by sticking. A step corresponding to the shape of the lower surface of the sensor-side connector 3 is formed in the connector fixing portion 12 so that the lower surface of the sensor-side connector 3 can be placed on top of each other. At the central portion of the connector fixing portion 12, a pair of plate-shaped portions 11 are formed so as to be spaced apart by the width dimension of the cord insertion portion 9. The pair of plate-shaped portions 11 are dimensioned to be slightly longer than the height of the cord insertion portion 9, and the claw portions 13 are formed on the top of the pair of plate-shaped portions 11 so as to project toward the opposite sides. I am trying to hold it down.

A pair of substantially L-shaped wall portions 14 connected to the pair of plate-shaped portions 11 are formed on the connector fixing portion 12 so as to face each other, and the side portion of the cord insertion portion 9 is sandwiched to insert the cord. I am trying to support part 9. Further, the connector fixing portion 12 is formed with a pair of wall portions 15 so that the connecting portion 10 can be supported by sandwiching the side portions of the connecting portion 10.

In the evaporator connector fixing device configured as described above, when the pair of plate-shaped portions 11 is pressed from above by the cord insertion portion 9 of the sensor-side connector 3, the pair of plate-shaped portions 11 bends outward, As a result, the cord insertion portion 9 is easily inserted between the pair of plate-shaped portions 11, and when the upper surface portion of the cord insertion portion 9 passes through the claw portion 13, the pair of plate-shaped portions 11 stand up. Then, the pair of claw portions 13 press down the cord insertion portion 9. As the claw portion 13 holds the cord insertion portion 9 in this manner, the sensor-side connector 3 is reliably fixed. In this state, at the same time, the walls 14 and 15 support the cord inserting portion 9 and the connecting portion 10, and the plate-like portion 11 and the claw portion 13 fix the cord inserting portion 9 as described above. Therefore, the sensor side connector 3 will be fixed more securely.

As described above, the sensor-side connector 3 can be fixed by pressing the sensor-side connector 3 against the pair of plate-shaped portions 11 and inserting it between the pair of plate-shaped portions 11. Since the sensor side connector 3 can be fixed, the mounting workability is excellent.

Compared to the one shown in FIGS. 11 and 12, the band 6 and the harness cover 7 are omitted to reduce the number of parts, so that the cost of the entire apparatus and the mounting workability can be improved. Also, in the case shown in FIGS. 11 and 12, there is a possibility that abnormal noise may be generated due to improper tightening or improper attachment of the band 6 or the harness cover 7, but in the present invention, it can be securely fixed as described above. As a result, there is no possibility of generating abnormal noise.

By securely fixing the sensor-side connector 3 as described above, it is possible to prevent a situation in which the evaporator sensor is pulled, and it is possible to prevent the sensor-side connector 3 from being caught by other parts. can avoid. Further, since the sensor side connector 3 can be securely fixed, the wiring work can be easily performed.

In this embodiment, the connector fixing portion 12 and then the plate-like portion 11 are integrally fixed to the evaporator case 1 by being attached, but the present invention is not limited to this. Alternatively, for example, the plate-shaped portion 11 may be formed by integrally molding the evaporator case 1. By integrally forming the plate-like portion 11 on the evaporator case 1 as described above, the number of parts of the entire apparatus can be further compressed to reduce the cost and improve the mounting workability.

[0016]

[Effect of the device]

 Since the present invention is the connector fixing device for the evaporator configured as described above, the connector attached here (sensor-side connector in the embodiment, other connector may be pressed) against the fixing device. As a result, this connector can be fixed with one touch. As a result, the mounting workability is excellent. Since the sensor-side connector is fixed by inserting it between the pair of plate-shaped parts, the sensor-side connector can be fixed securely. In addition, since the sensor-side connector is fixed without separately providing a fastening member such as a band or a harness cover, the number of parts can be reduced, the cost of the entire device can be reduced, and the mounting workability can be improved. be able to.
