Description

The present invention relates to a temperature sensor mounting jig used to attach a temperature sensor to a pipe.

Among the temperature sensors (using thermistor elements) used in home appliances, automobile-related products, electrical products, etc., there are those that are attached to pipes to measure the temperature of the pipes in order to detect the condition of gases or liquids, etc. that are supplied, circulated, or discharged through the pipes.
Conventionally, a temperature sensor has been known in which a leaf spring made of stainless steel or other thin metal plate with an anti-corrosive coating is used to secure the temperature sensor to the pipe, taking into consideration corrosion resistance, retention of mounting force against temperature history, ease of mounting, etc.

For example, Patent Document 1 describes a pipe clip that has a pipe holding part that holds a pipe, and a temperature sensor holding part that holds a temperature sensor (temperature sensor) that measures the temperature of the pipe, and is used to secure the temperature sensor to the pipe.

The above conventional techniques still have the following problems.
In the technology of the above-mentioned Patent Document 1, when mounting the sensor on a fixed pipe, the pipe insertion side needs to be opened widely to fit the sensor into the pipe, and in order to maintain sufficient holding force, the spring force needs to 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 mounting, mounting may not be easy for some workers. Therefore, it is conceivable to make the mounting work easier by setting the spring force of the holding part to a certain degree, but in that case, there is a problem that the holding force becomes insufficient, which is a factor that hinders stable temperature measurement. In addition, it becomes difficult to completely fix the sensor, and there is a risk that the temperature sensor or clip may come off the pipe due to an unexpected force.

The present invention was made in consideration of the above-mentioned problems, and aims to provide a temperature sensor mounting jig that has sufficient holding force and can be easily attached to piping.

The present invention employs the following configuration to solve the above-mentioned problems. That is, the temperature sensor mounting jig according to the first invention is a pair of temperature sensor mounting jigs used in a state where they are opposed to each other, and one of the pair of temperature sensor mounting jigs and the other of the pair of temperature sensor mounting jigs each have a pipe-side leaf spring portion into which a pipe can be fitted, and a sensor-side leaf spring portion into which a temperature sensor in contact with the pipe can be fitted, and one of the two has a protrusion, and the other faces the first one, and in a state where the pipe and the temperature sensor are sandwiched between the two, the protrusion of the first one fits into the spring. The pipe is fitted into the pipe-side leaf spring part of the one side and the temperature sensor is fitted into the sensor-side leaf spring part of the one side, and the other side is moved in the extension direction of the pipe toward the one side in a state where the pipe is fitted into the pipe-side leaf spring part of the other side at a position separated from the one side in the extension direction of the pipe, the temperature sensor can be fitted into the sensor-side leaf spring part, and the recess of the other side and the protrusion of the one side can be fitted into each other.

In this temperature sensor mounting jig, one of the two is provided with a convex portion, and the other is provided with a concave portion into which the convex portion of the one side can be fitted when the other side is opposed to the other side with the piping and temperature sensor sandwiched between them.Therefore, the temperature sensor can be easily attached to the piping with stable and sufficient holding force due to the spring force (spring force/elastic force) of the piping side plate spring portion against the fitted piping, as well as the fitting force between the concave portion and the convex portion.
In particular, when a pipe is fitted into one of the pipe side leaf spring portions and a temperature sensor is fitted into one of the sensor side leaf spring portions, and a pipe is further fitted into the other pipe side leaf spring portion at a position spaced away from one of the pipes in the extension direction of the pipes, the temperature sensor can be fitted into the sensor side leaf spring portion when the other of the pipes is moved toward the one of the pipes in the extension direction of the pipes, and the recess of the other of the pipes and the convex portion of the one of the pipes can fit into each other, so that the pipe can be easily fixed in a clamped state with a pair of temperature sensor mounting fixtures by sliding the other of the two fixtures toward the one of the pipes.
In addition, since the pair of temperature sensor mounting jigs sandwich the pipe and the temperature sensor from both sides, the heat of the pipe can be efficiently transferred to the temperature sensor. Also, by holding the pipe and the temperature sensor from both sides with the pair of temperature sensor mounting jigs that face each other and sandwich the pipe, a stronger holding force can be obtained compared to when fixing with only one jig.

The temperature sensor mounting jig of the second invention is characterized in that, in the first invention, one of the convex portions is formed on the pipe side leaf spring portion, and the other is provided with a pipe side uneven leaf spring portion having the concave portion that can be fitted into the convex portion of the pipe side leaf spring portion.
In other words, in this temperature sensor mounting jig, the other is equipped with a piping side unevenness leaf spring part having a concave part that can fit into the convex part of the piping side leaf spring part.By providing a separate piping side unevenness leaf spring part whose spring properties can be adjusted separately from the piping side leaf spring part, the fitting force between the concave part and the convex part can be adjusted separately from the spring properties of the piping side leaf spring part, and the pair of temperature sensor mounting jigs can be fixed more stably.
Furthermore, by overlapping the pipe side leaf spring part with the pipe fitted inside so as to be pressed down from the outside by the pipe side concave-convex leaf spring part and fitting the concave and convex parts together, it is possible to prevent the pipe side leaf spring part from opening due to unexpected force.

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 provided with a sensor side concave-convex leaf spring portion having the concave portion that can be fitted into the convex portion of the one of the sensor side leaf spring portions.
In other words, in this temperature sensor mounting jig, the other is equipped with a sensor side uneven leaf spring part having a recess that can fit into the convex part of the sensor side leaf spring part of the one of the temperature sensor side leaf spring parts.By providing a sensor side uneven leaf spring part whose spring properties can be adjusted separately from the sensor side leaf spring part, the fitting force between the recess and convex parts can be adjusted separately from the spring properties of the sensor side leaf spring part, and the pair of temperature sensor mounting jigs can be fixed more stably.
Furthermore, by overlapping the sensor side leaf spring part with the temperature sensor fitted inside so as to be pressed down from the outside by the sensor side concave-convex leaf spring part and fitting the concave and convex parts together, it is possible to prevent the sensor side leaf spring part from opening due to unexpected force.

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.
In other words, in this temperature sensor mounting jig, a pair of temperature sensor mounting jigs have the same shape, so by using two of the same parts, there is no need to create one with a different shape, and the unit cost of the part can be reduced.

In a fifth invention, in any of the first to fourth inventions, the one of the sensor side leaf spring portions is characterized in that it comprises a first leaf spring portion having the convex portion and into which the temperature sensor can be fitted, and a second leaf spring portion into which the temperature sensor can be fitted with a stronger spring force than the first leaf spring portion.
That is, in this temperature sensor mounting jig, the sensor side leaf spring portion is provided with a first leaf spring portion having a convex portion into which the temperature sensor can be fitted, and a second leaf spring portion into which the temperature sensor can be fitted with a stronger spring force than the first leaf spring portion.By providing the second leaf spring portion with a stronger spring force in addition to the first leaf spring portion having a convex portion, the fitting force for the temperature sensor can be set stronger than in the case of using only the first leaf spring portion, and the temperature sensor can be fixed more stably.

The sixth invention is characterized in that, in any of the first to fifth inventions, the sensor side leaf spring portion is provided with a sensor locking portion that abuts against an end of the temperature sensor to position it when the temperature sensor is fitted into its side end.
In other words, in this temperature sensor mounting jig, the sensor side leaf spring portion is equipped with a sensor locking portion that abuts against the end of the temperature sensor to position it when the temperature sensor is fitted into its side end, so that when the other is slid toward the one side to engage the respective convex and concave portions, the sensor locking portion prevents the temperature sensor from shifting out of position from the sensor side leaf spring portion.

According to the present invention, the following effects are obtained.
In other words, according to the temperature sensor mounting jig of the present invention, one of the two is provided with a convex portion, and the other is provided with a concave portion that can be fitted into the convex portion of the one of the two when the other is opposed to the other and the piping and temperature sensor are sandwiched between them.Therefore, the spring force of the piping side plate spring portion as well as the fitting force between the concave portion and the convex portion allow the temperature sensor to be easily attached to the piping with stable and sufficient holding force, and the heat of the piping sandwiched between the pair of temperature sensor mounting jigs can be efficiently transferred to the temperature sensor.
In particular, when a pipe is fitted into one of the pipe side leaf spring portions and a temperature sensor is fitted into one of the sensor side leaf spring portions, and a pipe is further fitted into the other pipe side leaf spring portion at a position spaced away from one of the pipes in the extension direction of the pipes, the temperature sensor can be fitted into the sensor side leaf spring portion when the other of the pipes is moved toward the one of the pipes in the extension direction of the pipes, and the recess of the other of the pipes and the convex portion of the one of the pipes can fit into each other, so that the pipe can be easily fixed in a clamped state with a pair of temperature sensor mounting fixtures by sliding the other of the two fixtures toward the one of the pipes.
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 large, and it is possible to prevent the pipe or temperature sensor from becoming detached due to an unexpected force. Also, since the spring force of the pipe-side leaf spring portion and the sensor-side leaf spring portion can be set to a level that allows an operator to easily perform installation, installation becomes as easy as or easier than before.

Below, one embodiment of a temperature sensor mounting jig according to the present invention will be described with reference to Figures 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 in a mutually opposing state as shown in Figures 1 to 6. One 1A of the pair of temperature sensor mounting jigs 1A and 1B and the other 1B of the pair of temperature sensor mounting jigs each have a pipe-side leaf spring portion 2 into which a pipe P can be fitted, and a sensor-side leaf spring portion 3 into which a temperature sensor S in contact with the pipe P can be fitted.

The one side 1A has a protrusion 4a.
The other side 1B is opposed to the first side 1A and has a recess 4b into which the protrusion 4a of the first side 1A can be fitted in a state in which the other side 1B sandwiches the pipe P and the temperature sensor S therebetween.
In this embodiment, the temperature sensor mounting jigs 1A, 1B have a pipe P fitted into the pipe side leaf spring portion 2 of the one side 1A and a temperature sensor S fitted into the sensor side leaf spring portion 3 of the one side 1A, and further have a pipe P fitted into the pipe side leaf spring portion 2 of the other side 1B at a position spaced away from the one side 1A in the extension direction of the pipe P. When the other side 1B is moved in the extension direction of the pipe P toward the one side 1A, the temperature sensor S can be fitted into the sensor side leaf spring portion 3 and the recess 4b of the other side 1B and the protrusion 4a of the one side 1A can be fitted into each other.

The convex portion 4a of the one side 1A is formed on the pipe-side leaf spring portion 2 and the sensor-side leaf spring portion 3. That is, the convex portion 4a of the one side 1A is a pair of curved portions provided on the end portion of the pipe-side leaf spring portion 2 and the end portion of the sensor-side leaf spring portion 3, and the outer side is a convex portion having an arc-shaped cross section.
The other 1B includes a pipe-side uneven leaf spring part 7 having a recess 4b that can fit with the protrusion 4a of the pipe-side leaf spring part 2, and a sensor-side uneven leaf spring part 9 having a recess 4b that can fit with the protrusion 4a of the sensor-side leaf spring part 3 of the other 1A. That is, the recess 4b of the other 1B is a pair provided by curving the pipe-side uneven leaf spring part 7 and the sensor-side uneven leaf spring part 9, and the inside is a recess having an arc-shaped cross section.

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

The pair of temperature sensor mounting jigs 1A, 1B each have an intermediate plate portion 6 which is continuous with the pipe side leaf spring portion 2 at the top and with the sensor side leaf spring portion 3 at the bottom, and the entire jig is formed by bending a single metal plate.
The intermediate plate portion 6 has a portion 6a protruding laterally, and a leaf spring portion 7 for piping side unevenness is formed continuously to the lower portion of the protruding portion 6a, and a leaf spring portion 9 for sensor side unevenness is formed continuously to the upper portion of the protruding portion 6a.
The intermediate plate portion 6 has an increased rigidity due to a protruding portion that extends in the protruding direction of the protruding portion 6a and is machined to have a convex cross section on the outside.

The temperature sensor S is formed, for example, in a cylindrical shape and contains a temperature-sensing element (not shown) such as a thermistor element. As shown in Figures 1 and 2, the temperature sensor S has a pair of lead wires L connected to the internal temperature-sensing element and extending from one end to the outside.
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 circumferential surface of the pipe P.
Further, the sensor side leaf spring portion 3 is curved along the outer peripheral surface of the temperature sensor S with a smaller radius of curvature than the pipe side leaf spring portion 2 and has an arcuate cross section.

In this way, the pipe-side leaf spring part 2 is curved along the outer peripheral surface of the pipe P, and the sensor-side leaf spring part 3 is curved along the outer peripheral surface of the temperature sensor S with a smaller radius of curvature than the pipe-side leaf spring part 2, so that the temperature sensor S can be firmly attached by the sensor-side leaf spring part 3, which has a small radius of curvature that provides a strong biasing force (spring force). In addition, because the pipe-side leaf spring part 2 has a larger radius of curvature than the sensor-side leaf spring part 3, the pipe-side leaf spring part 2 can be easily opened wide even with a relatively weak force, making it easy to attach to a thick pipe P.

Next, we will explain how to attach the temperature sensor S to the pipe P using a pair of temperature sensor attachment jigs 1A and 1B.

First, as shown in FIG. 1(a), a pipe P is fitted into the pipe-side leaf spring portion 2 of one of a pair of temperature sensor mounting jigs 1A, and a temperature sensor S is fitted into the sensor-side leaf spring portion 3 of the other jigs 1A. Even when only the other jigs 1A are used, the temperature sensor S can be held in contact with the pipe P, but the holding force of the pipe-side leaf spring portion 2 and the sensor-side leaf spring portion 3 is set to be relatively weak so that they can be easily spread apart during mounting.

Therefore, the other 1B of the pair of temperature sensor mounting jigs 1A, 1B is positioned away from the first 1A in the extension direction of the pipe P, and the pipe P is fitted into the pipe-side leaf spring portion 2 of the second 1B. Then, from this state, the second 1B is moved toward the first 1A in the extension 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.
In addition, the protruding portion 6a extends in the axial direction of the piping P when attached to the piping P, and when the other side 1B is slid toward the one side 1A, the protruding portion 6a is inserted between the sensor side unevenness leaf spring portion 9 and the piping side unevenness leaf spring portion 7 of the one side 1A.
At this time, the convex portions 4a and concave portions 4b of the pair of temperature sensor mounting jigs 1A and 1B are fitted into each other and fixed.

That is, the pair of temperature sensor mounting jigs 1A, 1B face each other, with the pair of recesses 4b of each overlapping the pair of protrusions 4a of the other, and are fitted together.
At this time, the sensor locking portion 8 of the other 1B abuts against the front end surface of the temperature sensor S to position the front end of the temperature sensor S. The sensor locking portion 8 of the other 1A abuts against the rear end surface of the temperature sensor S to position the rear end of the temperature sensor S.
In this way, when a pair of temperature sensor mounting fixtures 1A, 1B are attached in a state in which the temperature sensor S and the piping P are sandwiched between them, as shown in Figures 1(b) and 3, the pair of temperature sensor mounting fixtures 1A, 1B can firmly hold the temperature sensor S in contact with the piping P.

In this manner, in the pair of temperature sensor mounting jigs 1A, 1B of this embodiment, the one 1A has a convex portion 4a, and the other 1B faces the one 1A and has a concave portion 4b into which the convex portion 4a of the one 1A can be fitted when the other 1B faces the one 1A and sandwiches the piping P and the temperature sensor S. Therefore, the fitting force between the concave portion 4b and the convex portion 4a in addition to the spring force (biasing force/elastic force) of the piping side plate spring portion 2 against the fitted piping P allows the temperature sensor S to be easily attached to the piping P with a stable and sufficient holding force.

In particular, when the pipe P is fitted into the pipe-side leaf spring portion 2 of the first side 1A and the temperature sensor S is fitted into the sensor-side leaf spring portion 3 of the first side 1A, and the other side 1B is moved away from the first side 1A in the extension direction of the pipe P, the temperature sensor S can be fitted into the sensor-side leaf spring portion 3 when the other side 1B is moved toward the first side 1A in the extension direction of the pipe P, and the recess 4b of the other side 1B and the protrusion 4a of the first side 1A can be fitted into each other. Therefore, by sliding the other side 1B toward the first side 1A, the pipe can be easily fixed in a sandwiched state with the pair of temperature sensor mounting jigs 1A, 1B.

In addition, the pair of temperature sensor mounting jigs 1A, 1B sandwich the pipe P and the temperature sensor S from both sides, so the heat of the pipe P can be efficiently transferred to the temperature sensor S. In addition, the pair of temperature sensor mounting jigs 1A, 1B sandwich the pipe P facing each other, holding the pipe P and the temperature sensor S from both sides, respectively, can provide a higher holding force than when fixed with only one jig.

In addition, the other part 1B is equipped with a pipe-side unevenness leaf spring part 7 having a recess 4b that can be fitted into the protrusion 4a of the pipe-side leaf spring part 2. By separately providing the pipe-side unevenness leaf spring part 7, whose spring properties can be adjusted separately from the pipe-side leaf spring part 2, the fitting force between the recess 4b and the protrusion 4a can be adjusted separately from the spring properties of the pipe-side leaf spring part 2, and the pair of temperature sensor mounting jigs 1A, 1B can be fixed more stably.
Furthermore, by overlapping the pipe side leaf spring part 2 with the pipe P fitted inside by pressing it down from the outside with the pipe side uneven leaf spring part 7 and fitting the concave part 4b into the convex part 4a, it is possible to prevent the pipe side leaf spring part 2 from opening due to an unexpected force.

In addition, the other side 1B is equipped with a sensor side uneven leaf spring part 9 having a recess 4b that can be fitted into the convex part 4a of the sensor side leaf spring part 3 of the other side 1A. By separately providing the sensor side uneven leaf spring part 9, whose spring properties can be adjusted separately from the sensor side leaf spring part 3, the fitting force between the recess 4b and the convex part 4a can be adjusted separately from the spring properties of the sensor side leaf spring part 3, and the pair of temperature sensor mounting jigs 1A, 1B can be fixed more stably.
In addition, by overlapping the sensor side leaf spring part 3 with the temperature sensor S fitted inside by pressing it down from the outside with the sensor side uneven leaf spring part 9 and fitting the concave part 4b into the convex part 4a, it is possible to prevent the sensor side leaf spring part 3 from opening due to unexpected force.

Furthermore, since the pair of temperature sensor mounting jigs 1A, 1B are formed to be identical to each other in shape, by using two of the same parts, it is not necessary to manufacture parts of different shapes, and the cost per part can be reduced.
In addition, the sensor side leaf spring portion 3 of the one side 1A is equipped with a first leaf spring portion 3a having a convex portion 4a into which the temperature sensor S can be fitted, and a second leaf spring portion 3b into which the temperature sensor S can be fitted with a stronger spring force than the first leaf spring portion 3a.By providing the second leaf spring portion 3b with a stronger spring force in addition to the first leaf spring portion 3a having the convex portion 4a, the fitting force of the temperature sensor S can be set stronger than in the case of only the first leaf spring portion 3a, and the temperature sensor S can be fixed more stably.

In addition, the sensor side leaf spring part 3 is provided with a sensor locking part 8 that abuts against the end of the temperature sensor S to position it when the temperature sensor S is fitted into its side end, so that when the other part 1B is slid toward the one part 1A to fit the convex part 4a and the concave part 4b of each other, the sensor locking part 8 can prevent the temperature sensor S from shifting out of position from the sensor side leaf spring part 3.

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

For example, in the above embodiment, a pair of temperature sensor mounting jigs are formed from metal plates, but they may be formed from other materials such as resin. That is, in the present invention, sufficient holding force can be obtained even with resin, which has a weaker elasticity than metal plates. Furthermore, when molded from resin, if the piping or temperature sensor case is made of metal, corrosion caused by contact between dissimilar metals can be suppressed.

In the above embodiment, the other 1B of the pair of temperature sensor mounting jigs 1A, 1B is slid sideways over the pipe P relative to the other 1A to fit together, but the pair of temperature sensor mounting jigs 1A, 1B in the above embodiment can also be fitted together directly facing each other with the pipe P and temperature sensor S disposed between them, as shown in FIG. 7. In this case, the spring portion needs to be expanded more when fitting together than in the above case of sliding sideways, but this is applicable to cases where space cannot be secured to slide the temperature sensor mounting jig, such as when the pipe P is bent.
