Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
The configuration of the temperature sensor 1 will be described with reference to FIGS. 1 and 2. FIG. 1 is a schematic plan view of the temperature sensor 1 according to the first embodiment of the present invention. FIG. 2 is a schematic side view of the temperature sensor 1 according to the first embodiment of the present invention.

The temperature sensor 1 is an electronic component for detecting the temperature of an object to be measured and performing temperature compensation. As shown in FIG. 1, the temperature sensor 1 includes a temperature detecting element 12, a lead wire 13, a sealing member 11, and a reinforcing member 15. The temperature sensor is a contact type in which the temperature detection element directly or indirectly contacts the object to be measured to measure the temperature, and a non-contact type in which the temperature detection element measures the temperature without contacting the object to be measured. There is a formula, and the temperature sensor of the first embodiment is intended for the contact type.

The temperature detection element 12 is an electronic element whose resistance value changes with a change in temperature. The temperature detecting element 12 includes a terminal electrode 17 for electrically connecting to the lead wire 13.

Examples of the temperature detecting element of the contact type temperature sensor include a thermistor, a thermocouple, and a resistance temperature detector. In the present invention, any temperature detecting element may be used. For example, an NTC thermistor whose resistance value decreases as the temperature rises or a PTC thermistor whose resistance value sharply increases at a certain temperature when the temperature rises may be used. Good.

The connection portion between the lead wire 13 and the terminal electrode 17 of the temperature detection element 12 and the temperature detection element 12 are sealed by the sealing member 11. The sealing resin 11 can protect the lead wire 13, the connecting portion of the terminal electrode 17 of the temperature detecting element 12, and the temperature detecting element 12 itself. When the sealing member 11 comes into contact with the object to be measured, the heat energy generated from the object to be measured is transmitted to the temperature detecting element 12. The sealing member 11 is made of, for example, a resin, and specific examples thereof include an epoxy resin.

One end of the lead wire 13 is electrically connected to the terminal electrode 17 of the temperature detection element, and the other end is connected to the electrode of the substrate. The lead wire 13 may be made of a conductive material, and may be made of Cu—Ni as a main component, for example.

In the first embodiment, the temperature detection element 12 has two terminal electrodes 17, and the lead wire 13 is connected to each terminal electrode 17. The number of lead wires 13 may be increased or decreased according to the number of terminal electrodes 17 of the temperature detecting element 12.

The lead wire 13 may be covered with an insulating material in order to prevent contact with other conductive members and to prevent oxidation of the lead wire 13. As such an insulating material, for example, a resin such as polyurethane may be used. When the lead wire 13 is electrically connected to the terminal electrode 17 of the temperature detection element 12, the electrode of the substrate, or the like, the portion covered with the insulating material is peeled off. The exposed lead wire 13 is electrically connected to the terminal electrode 17 of the temperature detection element 12, the electrode of the substrate, and the like by using a conductive bonding material 16 such as solder.

As shown in FIGS. 1 and 2, the region between one end and the other end of the lead wire 13 is covered with the reinforcing member 15. Specifically, in the extending direction D3 of the lead wire 13, the region between the connection portion of the temperature detection element 12 with the terminal electrode 17 and the connection portion with the electrode of the substrate is covered with the reinforcing member 15. The reinforcing member 15 is made of, for example, a resin material, and is specifically selected from a resin material such as a polyurethane resin. By using the resin material, the slit portion 34 or the slot portion 14, which will be described later, can be easily processed. The insulating material covering the lead wire 13 and the reinforcing member 15 may be made of the same resin material. By being composed of the same resin material, the adhesion between the insulating material and the reinforcing member 15 can be improved.

As shown in FIG. 1, the reinforcing member 15 integrally covers the two lead wires 13. Here, the term "integrally covering the lead wires 13" means a state in which the plurality of lead wires 13 and the reinforcing member 15 covering each lead wire 13 are integrated into one member.

Next, the cross-sectional shape of the temperature sensor 1 will be described. FIG. 3 is a cross-sectional view taken along the line AA of the temperature sensor 1 shown in FIG. FIG. 4 is a cross-sectional view taken along the line BB of the temperature sensor 1 shown in FIG. FIG. 5 is a cross-sectional view taken along the line CC of the temperature sensor 1 shown in FIG. As shown in FIGS. 3 and 5, the cross-sectional area of the reinforcing member 15 is larger than the cross-sectional area of the lead wire 13 when viewed in cross section along the AA line and the CC line. By making the cross section of the reinforcing member 15 larger than the cross section of the lead wire 13, the lead wire 13 can be further reinforced.

As shown in FIGS. 1, 3 and 4, the length L1 of the reinforcing member 15 in the alignment direction D1 of the lead wires 13 is in the alignment direction D1 of the lead wires 13 and the direction D2 perpendicular to the extension direction D3 of the lead wires 13. The length of the reinforcing member 15 is longer than T1. With this configuration, it is easier to bend the reinforcing member 15 in the direction D1 in which the lead wires 13 are arranged and in the direction D2 perpendicular to the lead wires 13 than in the case where the reinforcing member 15 is bent in the direction D1 aligned with the lead wires 13. .. Here, the alignment direction D1 means a direction perpendicular to the extending direction D3 of the lead wire 13 in the plane of the temperature sensor 1 shown in FIG.

The slot portion 14 is formed to facilitate elastic deformation of the reinforcing member 15. The shape of the slot portion 14 is shown in FIGS. 1 and 2, and the slot portion 14 is formed in the reinforcing member 15 in a direction intersecting the extending direction of the lead wire 13. As shown in FIG. 1, the slot portion 14 is formed in the reinforcing member 15 so as to extend in the alignment direction D1 of the lead wires 13. According to this configuration, the length T1 of the reinforcing member 15 in which the slot portion 14 is formed in the direction D2 is shorter than the length T2 of the reinforcing member 15 in which the slot portion 14 is not formed in the direction D2. Therefore, the reinforcing member 15 can be easily bent toward the minus side in the direction D2.

In the reinforcing member 15, one slot portion 14 may be formed, or a plurality of slot portions 14 may be formed. By forming the plurality of slot portions 14, the stress at the time of bending is distributed to the plurality of slot portions 14 as compared with the case where the single slot portion 14 is formed, so that each slot portion 14 can be formed. It becomes difficult to break.

It is preferable that the slot portion 14 is formed in parallel with the alignment direction D1. According to such a configuration, when the two lead wires 13 are bent in the direction D2, the bending radii become the same, so that the bending stress is likely to be applied evenly. In addition, bending stress can be dispersed in a plurality of slot portions 14. Further, the slot portion 14 is formed so as to be continuous from one end side to the other end side of the reinforcing member 15 in the arrangement direction D1.

Next, the slot portion 24 will be described with reference to FIGS. 7A and 7B.

As shown in FIG. 7A, the slot portion 24 is a portion of the reinforcing member 25 before bending that has a concave shape having a constant width. The depth of the slot portion 24 is preferably such that the lead wire 13 is not exposed. The surface of the lead wire 13 can be protected without separately providing a protective film. In addition, the integrity of the plurality of lead wires 13 can be ensured.

As shown in FIG. 7B, when the slot portion 24 is bent, the width (length in direction D3) L4 of the entrance of the slot portion 24 is in the direction D3 rather than the width (length in direction D3) L5 of the bottom of the slot portion 24. The reinforcing member 25 is elastically deformed so as to spread.

As shown in FIG. 7A, the depth of the slot portion 24 (the length in the direction D2) is constant in the extending direction of the lead wire 23. With such a configuration, as shown in FIG. 7B, when the reinforcing member 25 is bent, bending stress is likely to be uniformly applied to the bottom of the slot portion 24, and the slot portion 24 can be made difficult to break.

As shown in FIG. 7A, the reinforcing member 15 is partially thinned in the slot portion 14. Therefore, it becomes easier to bend the reinforcing member 15 in the direction D2 than in the alignment direction D1.

FIG. 6 is a schematic side view when the temperature sensor 1 shown in FIGS. 1 and 2 is bent. As shown in FIG. 6, a plurality of slot portions 14 are formed in the reinforcing member 15. The reinforcing member 15 elastically deforms and bends at the position where each slot portion 14 is formed. According to such a configuration, since the reinforcing member 15 is elastically deformed and bent at the position where each slot portion 14 is formed, bending stress is dispersed in each slot portion 14. Therefore, each slot portion 14 is less likely to break. Further, by forming the plurality of slot portions 14, it is possible to bend more when the same bending stress is applied, as compared with the case where a single slot portion 14 is formed.

As shown in FIG. 4, the outer circumferences of the two lead wires 13 are covered with the reinforcing member 15. Since the slot portion 24 is not formed in the portion shown in FIG. 4 as compared with FIG. 3, the reinforcing member 15 is relatively thick. Therefore, the lead wire 13 can be reinforced.

As shown in FIG. 5, the two lead wires 13 are electrically connected to the terminal electrode 17 of the temperature detection element 12 via a conductive bonding material 16 such as solder. A part of the two lead wires 13 and the temperature detecting element 12 are sealed by the sealing member 11. The sealing member 11 has an elliptical shape in a cross-sectional view along the CC line, but is not limited to this, and may have a circular shape or a rectangular shape.

As shown in FIGS. 1 and 2, the terminal electrodes 17 of the temperature detection element 12 are arranged on one side of the two or more lead wires 13 in the direction perpendicular to the arrangement surface of the lead wires 13. There is. Here, the aligned surface of the lead wires 13 is surrounded by a wire connecting one ends of the lead wires 13 and a wire connecting the other ends of the lead wires 13 in a state where the temperature sensor 1 is not bent. Refers to the surface. Similarly, in the reinforcing member 15, it is preferable that the slot portion 14 is formed on one side. According to this configuration, the temperature sensor 1 presses against the object to be measured by the elastic force of the reinforcing member 15 forming the slot portion 14. Therefore, the temperature sensor 1 can be stably brought into contact with the object to be measured.

From the above configuration, in the first embodiment, the lead wire 13 is integrally covered with the reinforcing member 15, and the reinforcing member 15 is provided with the slot portion 14. Therefore, even if the lead wire 13 is made thinner in accordance with the miniaturization of the temperature sensor 1, the strength of the lead wire 13 is ensured by the reinforcing member 15. Further, even when the lead wire 13 is plastically deformed due to bending, the temperature sensor 1 can be stably brought into contact with the object to be measured by using the elastic force of the reinforcing member 15 in which the slot portion 14 is formed.

(Embodiment 2)
Next, as the temperature sensor mounting structure according to the second embodiment of the present invention, a mode for detecting the temperature of the object to be measured 200 by using the temperature sensor 1 of the first embodiment will be described. FIG. 8 is a diagram showing a structure in which the temperature sensor 1 is attached to the substrate 300. The temperature sensor mounting structure 100 includes a temperature sensor 1 and a substrate 300. Since the temperature sensor 1 has the same configuration as the temperature sensor described in the first embodiment, the description thereof will be omitted. The sealing member 11 of the temperature sensor 1 is in contact with the object to be measured 200. Further, one end of the lead wire 13 is connected to the substrate side electrode of the substrate 300 as a connection terminal 18 from which the coated insulating material is peeled off. When the lead wire 13 is not covered with an insulating material, one end of the lead wire 13 is directly connected to the substrate side electrode of the substrate 300 as a connection terminal 18. The substrate-side electrode is formed, for example, by forming a hole in the substrate 300 and plating the hole. The substrate side electrode and the lead wire 13 are connected via a conductive bonding material such as solder. Although the lead wire 13 is inserted into the hole of the substrate 300 in the direction perpendicular to the substrate 3, the lead wire 13 may be inserted in the direction inclined with respect to the substrate 300.

As shown in FIG. 8, the temperature sensor 1 is bent between the substrate 300 and the measurement object 200. Specifically, the reinforcing member 15 is bent so that the postures of the portion on one side and the portion on the other side in the extending direction of the lead wire 13 with respect to the forming position of the slot portion 14 are different from each other, and the reinforcing member 15 as a whole It has a curved shape. Further, the sealing member 11 is in contact with the object to be measured 200 in the direction opposite to the bending direction of the reinforcing member 15. That is, in FIG. 8, the portion on the upper surface side of the sealing member 11 is in contact with the object to be measured 200. With such a configuration, the temperature sensor 1 can be stably brought into contact with the measurement object 200 by utilizing the elastic force of the slot portion 14 formed in the reinforcing member 15.

As shown in FIG. 8, the lead wire 13 extends in a direction inclined with respect to the normal direction of the surface of the substrate 300, and is bent so that the lead wire 13 extends in a direction opposite to the direction of inclination. Specifically, the lead wire 13 extends in the + D2 direction at an inclination angle α with respect to the normal direction of the surface of the substrate 300, and the inclination angle β with respect to the normal direction of the surface (virtual surface S) along the D1D2 plane. It is bent so as to extend in the -D2 direction. Miniaturization is required as one of the needs of temperature sensors in recent years. However, in order to resin-mold the reinforcing member 15 on the small lead wire 13 by mold molding or the like, a constant length of the lead wire 13 is required, which has been an obstacle to miniaturization of the temperature sensor. Therefore, the lead wire 13 extends in the direction of inclination from the substrate 300, and is bent so as to extend in the direction opposite to the direction of inclination, so that the temperature sensor can secure a constant length of the lead wire 13. 1 can be miniaturized.

Next, the temperature detection method of the temperature sensor 1 will be described. When detecting the temperature, the sealing member 11 is brought into contact with the object to be measured 200 to conduct heat to the sealing member 11. As a result, the temperature of the temperature detecting element 12 changes from the reference temperature t1 to the temperature t2 of the object to be measured. After that, the resistance value of the temperature detecting element 12 changes from the fixed resistance r2 to the resistance value r1 according to the temperature of the object to be measured. At that time, the resistance value r1 of the temperature detecting element 12 and the resistance voltage dividing of the fixed resistance r2 change. A control circuit (eg, ASIC) is used to convert the resistance partial pressure into temperature. For example, the reference temperature t1 is room temperature. Further, the temperature t2 of the object to be measured includes the temperature of the allowable measurement error.

(Modification example 1)
A modification 1 of the temperature sensor of the first embodiment (the temperature sensor of FIG. 1) will be described. The temperature sensor 101 according to the first modification shown in FIG. 9 shows a structure having a portion in which the lead wires 113 are arranged and spread in the direction D1 in the portion covered with the reinforcing member 115. The side view has the same structure as that of FIG. 2, and the reinforcing member 115 is provided with a plurality of slot portions 114. In the temperature sensor 101 of FIG. 9, the first region R1 in which the distance between the two lead wires 113 is narrow, the second region R2 in which the distance between the two lead wires 113 is wider than the first region R1, and the first region R1 The configuration is different from that of the temperature sensor 1 of FIG. 1 in that it includes a third region R3 that connects the second region R2 and the second region R2. The temperature detection element 112 is mounted in the first region R1. According to such a configuration, the rigidity of the lead wires 113 in the arranging direction D1 is improved, so that the direction in which the lead wires are easily bent can be more specified.

(Modification 2)

The temperature sensor 201 according to the modified example 2 shown in FIG. 10 has a structure in which a plurality of slot portions 214 are formed along a direction inclined with respect to the extending direction D3 of the lead wire 213 and the arranging direction D1 of the lead wire 213. Have. Further, the plurality of slot portions 214 are formed in parallel with each other. The slot portion 214 shown in FIG. 10 is different from the slot portion 14 of the temperature sensor of FIG. 1 in that it is not parallel to the arrangement direction D1 of the lead wires 213. According to such a configuration, the reinforcing member 215 is easily bent in the direction perpendicular to the forming direction of the slot portion 214. Therefore, it becomes easy to bend in a specific direction, and the sealing member 211 can be stably brought into contact with the measurement object even if the measurement object is arranged at a complicated position. In the temperature sensor of the present disclosure, it is sufficient that the slit portion or the slot portion is formed in the reinforcing member in the direction intersecting the direction in which the lead wire extends.

FIG. 11B shows the shape of the reinforcing member 35 shown in FIG. 11A when bent. As shown in FIG. 11B, when the slit portion 34 is bent, the entrance of the cut extends to a length L2. Since the notch is widened when bent, the reinforcing member 35 is easily elastically deformed. It is preferable that the slit portion 34 has a depth such that the lead wire 13 is not exposed when bent.

As shown in FIG. 11A, the depth of the slit portion 34 is constant in the extending direction D3 of the lead wire 33. With such a configuration, when the reinforcing member 35 is bent as shown in FIG. 11B, bending stress is likely to be uniformly applied to the bottom of the slit portion 34, so that the slit portion 34 can be made difficult to break.
