A plumbing clip for is described.

Japanese Patent Application Laid-Open No. 2002-340453

The following problems remain in the above conventional technique.
In the technique of Patent Document 1, when attaching to a fixed pipe, it is necessary to open the pipe insertion side widely and fit it into the pipe, and to maintain a sufficient holding force, the spring force must be set large. . However, since a strong force is required to open the pipe insertion side against the spring force (biasing force/elastic force) during installation, the installation may not be easy for some workers. Therefore, it is conceivable to make the mounting work easier by lowering the spring force of the holding part to some extent. There was an inconvenience. In addition, complete fixation becomes difficult, and there is a possibility that the temperature sensor or the clip may come off from the pipe due to unexpected force.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a temperature sensor mounting jig which has a sufficient holding force and which can be easily mounted to a pipe.

In order to solve the above problems, the present invention employs the following configurations. That is, a temperature sensor mounting jig according to a first aspect of the present invention is a pair of temperature sensor mounting jigs used in a state of facing each other, wherein one of the pair of temperature sensor mounting jigs The other of the pair of temperature sensor mounting jigs includes a pipe-side leaf spring portion into which a pipe can be fitted, and a sensor-side leaf spring portion into which the temperature sensor in contact with the pipe can be fitted. , the one has a convex portion, the other has a concave portion into which the one convex portion can be fitted in a state of facing the one and sandwiching the pipe and the temperature sensor, and The pipe is fitted into the pipe-side leaf spring portion, the temperature sensor is fitted into the one sensor-side leaf spring portion, and the other pipe is installed at a position separated from the one in the extending direction of the pipe. The temperature sensor can be fitted into the sensor-side leaf spring portion when the other side is moved in the direction in which the pipe extends toward the one side while the piping is fitted in the side leaf spring portion. The concave portion on the other side and the convex portion on the one side can be fitted to each other.

In this temperature sensor mounting jig, one of the jigs has a projection, and the other has a recess into which the projection of the one can be fitted in a state in which the pipe and the temperature sensor are sandwiched between the one and the other. Therefore, in addition to the spring force (biasing force/elastic force) of the pipe-side plate spring against the inserted pipe, the fitting force between the concave and convex portions allows the temperature sensor to be easily and stably held on the pipe. can be installed.
In particular, a pipe is fitted into the one pipe-side leaf spring portion, a temperature sensor is fitted into the one sensor-side leaf spring portion, and the other pipe is separated from the one in the extending direction of the pipe. When the pipe is fitted in the side leaf spring portion and the other is moved toward the one in the extending direction of the pipe, the temperature sensor can be fitted into the sensor side leaf spring portion, and the temperature sensor can be fitted into the recess of the other side leaf spring portion. Since the one convex portion can be fitted to each other, by sliding the other to the one, the pipe can be easily fixed by sandwiching the pipe between the pair of temperature sensor mounting jigs.
Moreover, since the piping and the temperature sensor are sandwiched from both sides by the pair of jigs for attaching the temperature sensor, the heat of the piping can be efficiently transferred to the temperature sensor. In addition, by holding the pipe and the temperature sensor from both sides with a pair of temperature sensor mounting jigs that sandwich the pipe facing each other, a higher holding force can be achieved compared to the case where only one jig is used. Obtainable.

A temperature sensor mounting jig according to a second invention is a temperature sensor mounting jig according to the first invention, wherein the one convex portion is formed on the pipe-side leaf spring portion, and the other is the convex portion of the pipe-side leaf spring portion. It is characterized by comprising a leaf spring portion for pipe-side unevenness having the concave portion that can be fitted to each other.
That is, in this temperature sensor mounting jig, the other side is provided with the pipe side uneven plate spring portion having the concave portion that can be fitted with the convex portion of the pipe side plate spring portion. By separately providing a plate spring for unevenness on the pipe side whose springiness can be adjusted separately, it is possible to adjust the fitting force between the concave and convex portions separately from the springiness of the pipe side leaf spring. The jig can be fixed more stably.
In addition, the pipe-side leaf spring portion that fits the pipe inside is pressed from the outside by the pipe-side concave-convex leaf spring portion, and by fitting the concave portion and the convex portion together, the pipe-side leaf spring portion can be pushed by an unexpected force. It becomes possible to prevent it from opening.

In a third invention, in the first or second invention, the one of the convex portions is formed on the sensor-side leaf spring portion, and the other is formed on the one of the sensor-side leaf spring portions. It is characterized by comprising a leaf spring portion for sensor-side unevenness having the concave portion that can be fitted.
That is, in this temperature sensor mounting jig, the other is provided with the sensor side uneven plate spring portion having the concave portion that can be fitted with the convex portion of the one sensor side plate spring portion. By separately providing the leaf spring part for sensor-side unevenness whose springiness can be adjusted separately from the spring part, the fitting force between the recessed part and the convex part can be adjusted independently of the springiness of the sensor-side leaf spring part. The sensor mounting jig can be fixed more stably.
In addition, the sensor-side leaf spring portion, in which the temperature sensor is fitted inside, is overlapped from the outside by the sensor-side concave-convex leaf spring portion, and by fitting the recessed portion and the convex portion together, the sensor-side leaf spring portion receives an unexpected force. It becomes possible to prevent it from opening with

A fourth invention is characterized in that, in any one of the first to third inventions, the pair of temperature sensor mounting jigs have the same shape.
That is, in this temperature sensor mounting jig, since the pair of temperature sensor mounting jigs have the same shape, there is no need to manufacture different shapes by using the same two parts. , the unit cost of parts can be reduced.

In a fifth aspect of the invention, in any one of the first to fourth aspects, the one sensor-side leaf spring portion includes a first leaf spring portion having the convex portion and into which the temperature sensor can be fitted; It is characterized by comprising a second plate spring portion into which the temperature sensor can be fitted with a biasing force stronger than that of the first plate spring portion.
That is, in this temperature sensor mounting jig, one of the sensor-side leaf spring portions includes a first leaf spring portion having a convex portion and into which the temperature sensor can be fitted, and a temperature sensor with an urging force stronger than that of the first leaf spring portion. Since the sensor is provided with the second plate spring portion into which the sensor can be fitted, the second plate spring portion having a strong urging force is separately provided in addition to the first plate spring portion having the convex portion. The fitting force of the temperature sensor can be set stronger than in the case of only one, and the temperature sensor can be fixed more stably.

In a sixth invention, in any one of the first to fifth inventions, the sensor-side leaf spring portion abuts and positions the end portion of the temperature sensor when the temperature sensor is fitted to the side end portion of the leaf spring portion. It is characterized by comprising a sensor locking portion that
That is, in this temperature sensor mounting jig, the sensor-side leaf spring portion has a sensor locking portion that abuts and positions the end portion of the temperature sensor when the temperature sensor is fitted to the side end portion of the sensor side leaf spring portion. The sensor locking portion can prevent the temperature sensor from being displaced from the sensor-side leaf spring portion when the other is slid to the one side and the convex portion and the concave portion are fitted to each other.

ADVANTAGE OF THE INVENTION According to this invention, there exist the following effects.
That is, according to the jig for mounting a temperature sensor according to the present invention, the one is provided with a convex portion, and the other is opposed to the one and sandwiches the pipe and the temperature sensor. Since the temperature sensor is provided with a recess that can be fitted into the pipe, the fitting force between the recess and the projection in addition to the spring force of the leaf spring on the side of the pipe allows the temperature sensor to be easily attached to the pipe with a sufficient and stable holding force. The heat of the piping sandwiched by the temperature sensor mounting jig can be efficiently transmitted to the temperature sensor.
In particular, a pipe is fitted into the one pipe-side plate spring portion, a temperature sensor is fitted into the one sensor-side plate spring portion, and the other pipe is separated from the one in the extending direction of the pipe. When the pipe is fitted in the side leaf spring portion and the other is moved toward the one in the extending direction of the pipe, the temperature sensor can be fitted into the sensor side leaf spring portion, and the temperature sensor can be fitted into the recess of the other side leaf spring portion. Since the one convex portion can be fitted to each other, by sliding the other to the one, the pipe can be easily fixed by sandwiching the pipe between the pair of temperature sensor mounting jigs.
Therefore, with the temperature sensor mounting jig of the present invention, a sufficiently high holding force can be obtained without setting the spring force of the pipe-side leaf spring portion to be large. occurrence can be prevented. In addition, since the spring forces of the pipe-side leaf spring portion and the sensor-side leaf spring portion can be set to such an extent that an operator can easily attach them, attachment can be performed as easily as in the conventional art.

An embodiment of a temperature sensor mounting jig according to the present invention will be described below with reference to FIGS. 1 to 6. FIG.

As shown in FIGS. 1 to 6, the temperature sensor mounting jigs 1A and 1B of this embodiment are a pair of temperature sensor mounting jigs that are used facing each other. One 1A of the mounting jigs 1A and 1B and the other 1B of the pair of temperature sensor mounting jigs are the pipe side leaf spring portion 2 into which the pipe P can be fitted, and the temperature at which the pipe P is brought into contact. A sensor-side leaf spring portion 3 into which the sensor S can be fitted is provided.

The one 1A is provided with a convex portion 4a.
The other 1B is provided with a concave portion 4b into which the convex portion 4a of the one 1A can be fitted in a state in which the piping P and the temperature sensor S are sandwiched between the one 1A and the other 1B.
In the temperature sensor mounting jigs 1A and 1B of the present embodiment, the pipe P is fitted into the pipe-side leaf spring portion 2 of the one 1A, the temperature sensor S is fitted into the sensor-side leaf spring portion 3 of the one 1A, and the temperature sensor S is fitted into the other one 1A. In a state where the pipe P is fitted in the pipe-side plate spring portion 2 of the other 1B at a position where the pipe 1B is separated from the one 1A in the extending direction of the pipe P, the other 1B is directed toward the one 1A. , the temperature sensor S can be fitted into the sensor-side leaf spring portion 3, and the concave portion 4b of the other 1B and the convex portion 4a of the one 1A can be fitted to each other.

The convex portion 4a of the one 1A is formed on the pipe-side leaf spring portion 2 and the sensor-side leaf spring portion 3. As shown in FIG. That is, the projections 4a of the one 1A are a pair of projections that are curved at the end of the pipe-side leaf spring portion 2 and at the end of the sensor-side leaf spring portion 3, respectively, and have arcuate cross-sections on the outside. It has become.
The other 1B includes a pipe-side concave/convex plate spring portion 7 having a concave portion 4b that can be fitted with the convex portion 4a of the pipe-side plate spring portion 2, and the convex portion 4a of the sensor-side plate spring portion 3 of the one 1A. It is provided with a leaf spring portion 9 for sensor-side unevenness having a recessed portion 4b that can be fitted. That is, the concave portion 4b of the other 1B is a pair of concave and convex spring portions 7 on the pipe side and a leaf spring portion 9 for concave and convex portions on the sensor side. there is

The pair of temperature sensor mounting jigs 1A and 1B have the same shape.
The sensor-side leaf spring portion 3 of the one 1A includes a first leaf spring portion 3a having a convex portion 4a and into which the temperature sensor S can be fitted, and a biasing force stronger than that of the first leaf spring portion 3a to which the temperature sensor S can be fitted. and a second leaf spring portion 3b.
A pair of the second plate spring portions 3b are formed in the bending direction of the sensor-side plate spring portion 3 and can be fitted so as to sandwich the temperature sensor S therebetween. That is, the second plate spring portion 3b is divided inside the first plate spring portion 3a by a U-shaped slit, and is curved with a radius of curvature smaller than that of the first plate spring portion 3a.
The sensor-side leaf spring portion 3 has a sensor locking portion 8 that abuts and positions the end of the temperature sensor S when the temperature sensor S is fitted in the side end of the sensor side leaf spring portion 3 .

The pair of temperature sensor mounting jigs 1A and 1B includes an intermediate plate portion 6 having a pipe-side leaf spring portion 2 continuous at its upper portion and a sensor-side leaf spring portion 3 continuous at its lower portion. It is formed by bending a single metal plate.
The intermediate plate portion 6 has a portion 6a protruding sideways, and a plate spring portion 7 for pipe-side unevenness is continuously formed at the lower portion of the protruding portion 6a. The leaf spring portion 9 for sensor-side unevenness is formed continuously.
The intermediate plate portion 6 is enhanced in rigidity by a ridge portion that extends in the projecting direction of the projecting portion 6a and is processed to have a convex cross section outward.

The temperature sensor S is formed, for example, in a columnar shape, and a temperature sensing element (not shown) such as a thermistor element is accommodated therein. Further, as shown in FIGS. 1 and 2, the temperature sensor S has a pair of lead wires L connected to internal temperature sensitive elements extending outside from one end thereof.
The outer diameter of the pipe P is larger than the outer diameter of the temperature sensor S, and the pipe-side leaf spring portion 2 is curved along the outer peripheral surface of the pipe P. As shown in FIG.
Further, the sensor-side leaf spring portion 3 is curved along the outer peripheral surface of the temperature sensor S to have a radius of curvature smaller than that of the pipe-side leaf spring portion 2 and has an arcuate cross section.

Thus, the pipe-side leaf spring portion 2 curves along the outer peripheral surface of the pipe P, and the sensor-side leaf spring portion 3 has a smaller radius of curvature than the pipe-side leaf spring portion 2 along the outer peripheral surface of the temperature sensor S. Therefore, the temperature sensor S can be firmly attached to the temperature sensor S by the sensor-side leaf spring portion 3 having a small radius of curvature that provides a strong biasing force (spring force). Further, since the pipe-side leaf spring portion 2 has a radius of curvature larger than that of the sensor-side leaf spring portion 3, the pipe-side leaf spring portion 2 can be easily opened even with a relatively weak force, and can be easily attached to a thick pipe P.

Next, a method for attaching the temperature sensor S to the pipe P using a pair of temperature sensor attachment jigs 1A and 1B will be described.

First, as shown in FIG. 1A, the pipe P is fitted into the pipe-side leaf spring portion 2 of one 1A of the pair of temperature sensor mounting jigs, and the sensor-side leaf spring portion 3 of the one 1A is fitted with a temperature sensor. Fit the sensor S. The temperature sensor S can be held in contact with the pipe P even when only the one 1A is used. Power is set relatively weak.

Therefore, the pipe P is fitted to the pipe-side plate spring portion 2 of the other 1B of the pair of temperature sensor mounting jigs 1A and 1B at a position where the other 1B is separated from the one 1A in the extending direction of the pipe P. enter. Then, from this state, the other 1B is moved toward the one 1A in the extending direction of the pipe P (the direction of the arrow in FIG. 1(a)), and the temperature sensor S is fitted into the sensor-side leaf spring portion 3. .
Further, the protruding portion 6a extends in the axial direction of the pipe P when attached to the pipe P, and when the other 1B is slid toward the one 1A, the protruding portion 6a On the other hand, it is inserted between the sensor-side concave-convex leaf spring portion 9 and the pipe-side concave-convex leaf spring portion 7 of 1A.
At this time, the convex portion 4a and the concave portion 4b of the pair of temperature sensor mounting jigs 1A and 1B are fitted and fixed.

In other words, the pair of temperature sensor mounting jigs 1A and 1B face each other, and the pair of concave portions 4b overlap the pair of convex portions 4a of the mating member so that they are fitted to each other.
Also, at this time, the sensor locking portion 8 of the other 1B comes into contact with the tip surface of the temperature sensor S, and the tip of the temperature sensor S is positioned. The rear end surface of the temperature sensor S is brought into contact with the sensor latching portion 8 of the one 1A so that the rear end of the temperature sensor S is positioned.
Thus, when the pair of temperature sensor mounting jigs 1A and 1B are mounted with the temperature sensor S and the pipe P sandwiched therebetween as shown in FIGS. 1B and 3, the pair of temperature sensors The temperature sensor S can be firmly held in contact with the pipe P by the mounting jigs 1A and 1B.

As described above, in the pair of temperature sensor mounting jigs 1A and 1B of the present embodiment, the one 1A has the convex portion 4a, and the other 1B faces the one 1A and supports the pipe P and the temperature sensor S. Since the convex portion 4a of the one 1A is provided with a concave portion 4b that can be fitted in the sandwiched state, in addition to the spring force (biasing force/elastic force) of the pipe side leaf spring portion 2 against the pipe P that is fitted, the concave portion 4b The temperature sensor S can be easily attached to the pipe P with a stable and sufficient holding force due to the fitting force of the projection 4a.

In particular, the pipe P is fitted in the pipe-side leaf spring portion 2 of the one 1A, the temperature sensor S is fitted in the sensor-side leaf spring portion 3 of the one 1A, and the other 1B is extended in the extending direction of the pipe P from the one 1A. In a state where the pipe P is fitted in the pipe-side leaf spring portion 2 of the other 1B at a spaced apart position, when the other 1B is moved in the extending direction of the pipe P toward the one 1A, the sensor-side leaf spring The temperature sensor S can be fitted into the portion 3, and the concave portion 4b of the other 1B and the convex portion 4a of the one 1A can be fitted to each other. The temperature sensor mounting jigs 1A and 1B can be used to easily fix the piping in a sandwiched state.

Further, since the pipe P and the temperature sensor S are sandwiched from both sides by the pair of temperature sensor mounting jigs 1A and 1B, the heat of the pipe P can be efficiently transferred to the temperature sensor S. Further, by holding the pipe P and the temperature sensor S from both sides by a pair of temperature sensor mounting jigs 1A and 1B that sandwich the pipe P so as to face each other, compared to the case of fixing with only one jig, , a higher holding force can be obtained.

In addition, since the other 1B is provided with the pipe side concave/convex plate spring portion 7 having the convex portion 4a of the pipe side plate spring portion 2 and the concave portion 4b that can be fitted to each other, a spring is provided separately from the pipe side plate spring portion 2. By separately providing the pipe-side concave-convex plate spring portion 7 whose elasticity can be adjusted, the fitting force between the concave portion 4b and the convex portion 4a can be adjusted independently of the spring property of the pipe-side plate spring portion 2, and the pair of temperature sensors can be attached. The jigs 1A and 1B can be fixed more stably.
Further, the pipe-side leaf spring portion 2 with the pipe P fitted inside is overlapped so as to be pressed from the outside by the pipe-side uneven leaf spring portion 7, and the concave portion 4b and the convex portion 4a are fitted together to form the pipe-side leaf spring portion. 2 can be prevented from opening by an unexpected force.

In addition, since the other 1B includes the sensor-side concave-convex flat spring portion 9 having the concave portion 4b that can be fitted with the convex portion 4a of the sensor-side flat spring portion 3 of the one 1A, the sensor-side flat spring portion 3 By separately providing the sensor-side concave-convex leaf spring portion 9 whose springiness can be adjusted separately, the fitting force between the concave portion 4b and the convex portion 4a can be adjusted independently of the springiness of the sensor-side leaf spring portion 3. temperature sensor mounting jigs 1A and 1B can be fixed more stably.
Further, the sensor-side leaf spring portion 3, in which the temperature sensor S is fitted inside, is overlaid so as to be pressed down by the sensor-side uneven leaf spring portion 9 from the outside, and the concave portion 4b and the convex portion 4a are fitted together to form a sensor-side leaf spring. It becomes possible to prevent the part 3 from opening by an unexpected force.

Since the pair of temperature sensor mounting jigs 1A and 1B have the same shape, using two of the same parts eliminates the need to manufacture different shapes, thereby reducing the unit cost of the parts. be able to.
Further, the sensor-side leaf spring portion 3 of the one 1A is a first leaf spring portion 3a having a convex portion 4a and into which the temperature sensor S can be fitted, and the temperature sensor S is urged by an urging force stronger than that of the first leaf spring portion 3a. Since the second plate spring portion 3b that can be fitted is provided, the second plate spring portion 3b having a strong urging force is separately provided separately from the first plate spring portion 3a having the convex portion 4a. The fitting force of the temperature sensor S can be set stronger than when only the spring portion 3a is used, and the temperature sensor S can be fixed more stably.

Further, since the sensor-side leaf spring portion 3 is provided with the sensor locking portion 8 that abuts and positions the end portion of the temperature sensor S when the temperature sensor S is fitted in the side end portion thereof, the other 1B can be moved. The sensor locking portion 8 can prevent the temperature sensor S from being displaced from the sensor-side leaf spring portion 3 when the convex portion 4a and the concave portion 4b are fitted to each other by sliding to the side of the one 1A. .

The technical scope of the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.

For example, in the above embodiment, the pair of temperature sensor mounting jigs are made of metal plates, but they may be made of other materials such as resin. That is, in the present invention, a sufficient holding force can be obtained even with a resin or the like having an elastic force weaker than that of a metal plate. In addition, when molding with resin, when the piping and the case of the temperature sensor are made of metal, it is possible to suppress the occurrence of corrosion due to contact between dissimilar metals.

Further, in the above embodiment, the other 1B of the pair of temperature sensor mounting jigs 1A and 1B is laterally slid with respect to the other 1A on the pipe P and fitted to each other. As shown in FIG. 7, the mounting jigs 1A and 1B can also be directly fitted to face each other with the pipe P and the temperature sensor S arranged between them. In this case, it is necessary to widen the spring portion when fitting compared to the case of lateral sliding described above. is.
