In the following description, the same elements are denoted by the same reference symbols in all the drawings, and redundant description is omitted.

  FIG. 1 is a perspective view of the temperature sensor 10. The temperature sensor 10 includes a case 12, a temperature measuring element 20 accommodated in the internal space 14 of the case 12, two lead wires 22 and 23 drawn from the temperature measuring element 20, a separator 40, and a case 12 after accommodating these. And the resin 58 filled in the internal space 14. Although the case 12 is opaque, in FIG. 1 and subsequent figures, the case 12 is shown in a transparent manner so that the arrangement state of the case 12 in the internal space 14 can be understood.

  FIG. 1 shows (a) and (b). If (a) is a perspective view seen from the front side, (b) is a perspective view seen from the back side with (a) turned over. It is. In order to understand these directions, FIG. 1 shows the X direction, the Y direction, and the Z direction as three directions orthogonal to each other. The X direction is a direction in which the lead wires 22 and 23 are arranged, and is referred to as a width (W) direction. The Y direction is orthogonal to the direction in which the lead wires 22 and 23 are arranged, and is also orthogonal to the direction in which the lead wires 22 and 23 extend, and is referred to as a height (H) direction. The Z direction is a direction connecting the bottom surface and the opening in the case 12, and the lead wires 22 and 23 are extending in the lead wires 22 and 23, and this is called a longitudinal (L) direction.

  This temperature sensor 10 includes a height direction positioning portion 50 for positioning in the height (H) direction, and positioning in the width (W) direction in order to accurately position the temperature measuring element 20 in the internal space 14 of the case 12. The separator 40 having the width direction positioning portions 52 and 53 to be performed and the longitudinal direction positioning portion 54 for positioning in the longitudinal (L) direction is used.

  FIG. 2 is a view of the temperature sensor 10 as viewed from the insertion port 16 side. The height direction positioning portion 50 of the separator 40 extends in the height direction, and is a separation wall that separates the two lead wires 22 and 23, and the top portion thereof abuts against the inner side surface of the internal space 14 of the case 12. Is done. The width direction positioning portions 52 and 53 of the separator 40 extend in the width direction and are plate portions that mount and hold the two lead wires 22 and 23, and end portions in the width direction of the internal space 14 of the case 12. It abuts on the inner surface.

  The height direction positioning portion 50 and the width direction positioning portions 52 and 53 can accurately position the separator 40 in the cross section perpendicular to the longitudinal direction of the internal space 14 of the case 12, and the lead wires 22 and 23 and the tips thereof can be positioned. The temperature measuring element 20 can be accurately positioned. Therefore, the height direction positioning portion 50 and the width direction positioning portions 52 and 53 are cross-sectional positioning portions of the internal space 14 in the case 12 of the separator 40. Further details of the positioning function of the separator 40 will be described later.

  The case 12 is a storage container that includes a bottom surface, side surfaces, and an opening facing the bottom surface, has a substantially rectangular parallelepiped shape that is long in the Z direction, and has an inner space 14 having an oval cross section perpendicular to the Z direction. One end of the internal space 14 in the + Z direction is a narrowed inner bottom, and the other end in the −Z direction is opened to serve as an insertion port 16 for the temperature measuring element 20 or the like. As shown in FIG. 1B, the insertion port 16 is provided with a notch 18 on the back surface side. The notch 18 has a notch position 19 that is entered by ΔL in the + Z direction from the end in the −Z direction on the surface side. The resin 58 is filled from the inner bottom portion of the internal space 14 to the notch position 19.

  The case 12 can be formed by using a suitable resin material and molded into a predetermined shape. Injection molding can be used as the molding method. As the resin material, a resin suitable for injection molding can be used. For example, an epoxy resin, a polyphenylene sulfide (PPS) resin, or the like can be used. Although an opaque material is used as the resin material, it may be transparent.

  As the resin 58 filled in the internal space, a resin having appropriate heat resistance can be used. For example, an epoxy resin or the like can be used.

  FIG. 3 is a diagram illustrating a portion that is housed in the internal space 14 of the case 12. The internal space 14 accommodates a separator 40, a temperature measuring element 20 mounted on the separator 40, and lead wires 22 and 23 drawn from the temperature measuring element 20.

  The temperature measuring element 20 is a temperature detecting element, for example, a thermistor. Since the thermistor is a resistor whose electrical resistance changes greatly with respect to temperature change, lead wires 22 and 23 are drawn from both terminals, and a predetermined voltage is applied between the lead wires 22 and 23 in an external measurement circuit. The temperature can be detected by measuring the current value at that time.

  The lead wires 22 and 23 are two signal lines connected to both terminals of the temperature measuring element 20. The number of signal lines may be two or more, and is not limited to two. The lead wires 22 and 23 are drawn from the temperature measuring element 20 to the insertion port 16 of the case 12 while gradually increasing the outer diameter. In the example of FIG. 3, the lead wires 22, 23 are wire diameters at the relay portions 28, 29 via single conductor wires 24, 25 drawn from the temperature measuring element 20, and insulation-coated wires 26, 27 with insulation coating added thereto. Are connected to a thick conductor stranded wire to form stranded wires 30 and 31 with insulation coating, and lead wires 32 and 33 protected by a strong insulating tube. This is an example. For example, the outer diameters of the lead wires 32 and 33, the insulating tubes, and the like are appropriately changed according to the specification of the temperature sensor 10.

  The separator 40 is an insulator component that holds the temperature measuring element 20 while securing the position thereof and mounts the two lead wires 22 and 23 separately from each other. As described with reference to FIG. 2, the outer shape of the separator 40 has a function of positioning with respect to the internal space 14 of the case 12.

  FIG. 4 is a perspective view showing the separator 40. The separator 40 has a glider-like shape in which the front end side holding the temperature measuring element 20 is tapered and the rear end side spreads in a wing shape. The separator 40 is inserted into the internal space 14 of the case 12 from the front end side, and at that time, the rear end side comes to the position of the insertion port 16 of the case 12.

  A temperature measuring element stopper portion 42 and two temperature measuring element positioning wall portions 43 and 44 are provided on both sides of the temperature measuring element stopper portion 42 so as to be spaced apart from each other at a predetermined interval. Further, a partition wall portion 48 is provided that is spaced apart from the temperature measuring element stopper portion 42 at a predetermined interval in the longitudinal direction and extends from the temperature measuring device stopper portion 42 to the rear end side along the longitudinal direction. These are provided so as to protrude in the height direction on the bottom plate portion 46 that is elongated in the longitudinal direction. The area 56 defined by the temperature measuring element stopper portion 42, the two temperature measuring element positioning wall portions 43, 44, the tip of the partition wall portion 48, and the upper surface of the bottom plate portion 46 is The temperature measuring element 20 is positioned and held in this region 56 in accordance with the outer shape. That is, the region 56 is a holding region of the temperature measuring element 20.

  The partition wall portion 48 is disposed along the longitudinal direction in the center portion of the bottom plate portion 46, and as shown in FIG. 3, the two lead wires 22 and 23 are separately disposed on both sides thereof. That is, the lead wire 23 is arranged in a region defined by the wall surface on the −X side of the partition wall portion 48 and the upper surface of the bottom plate portion 46, and is partitioned by the wall surface on the + X side of the partition wall portion 48 and the upper surface of the bottom plate portion 46. Lead wires 22 are arranged in the region.

  The height along the height direction of the partition wall portion 48 is maintained at a constant height as it goes from the front end side to the rear end side, and then gradually becomes higher. The maximum height is reached. The wall thickness along the width direction of the partition wall portion 48 also maintains a constant width at first, then gradually becomes wider, and becomes the maximum width at the height direction positioning portion 50. The width dimension of the bottom plate portion 46 gradually becomes wider from the front end side toward the height direction positioning portion 50, and becomes the same width dimension as the height direction positioning portion 50 in the height direction positioning portion 50, where the bottom plate portion 46 has a height. It is integrated with the direction positioning part 50.

  As shown in FIG. 3, a portion of the separator 40 from the tip of the partition wall portion 48 to the height direction positioning portion 50 functions as a guide wall for the lead wires 22 and 23, and is relayed by the height direction positioning portion 50. It functions as a separation wall that separates the portions 28 and 29. As described with reference to FIG. 2, the top portion 60 of the separation wall, which is the height direction positioning portion 50, comes into contact with the inner surface in the height direction of the internal space 14 of the case 12, thereby positioning the separator 40 in the height direction. Do. Accordingly, the top 60 of the separation wall is a substantial height direction positioning surface.

  As an extension of the partition wall portion 48, the rear end side of the height direction positioning portion 50 maintains the width dimension of the height direction positioning portion 50, and the height gradually decreases, so that the width direction positioning portion 52, It becomes the same height position as the upper surface of 53. This portion further extends to the rear end side, protrudes from the width direction positioning portions 52 and 53 to the rear end side, and becomes a longitudinal direction positioning portion 54.

  The width direction positioning portions 52 and 53 are trapezoidal airfoil portions provided on both sides in the width direction of a portion having the same width as the height direction positioning portion 50 and extending to the rear end side. The plate thickness of the width direction positioning portions 52 and 53 is set to be thicker than the plate thickness of the bottom plate portion 46. The width direction positioning parts 52 and 53 have side surfaces 62 and 63 parallel to the longitudinal direction on both sides of the trapezoidal airfoil. An interval dimension along the width direction between the side surface 62 and the side surface 63 is set to be smaller than a dimension in the width direction of the internal space 14 of the case 12 by a predetermined margin dimension. As described with reference to FIG. 2, the side surfaces 62 and 63 come into contact with the inner surface in the width direction of the internal space 14 of the case 12 to position the separator 40 in the width direction. Therefore, the side surfaces 62 and 63 are substantial width direction positioning surfaces.

  The longitudinal direction positioning portion 54 is a portion protruding at a predetermined length from the rear end side of the trapezoidal airfoil portion of the width direction positioning portions 52 and 53. When the separator 40 is inserted from the insertion port 16 of the case 12, the protruding amount is such that the position of the end portion 64 on the rear end side along the longitudinal direction of the longitudinal direction positioning portion 54 is the notch position of the notch portion 18 of the case 12. It is set to be 19. In other words, when the separator 40 is inserted into the internal space 14 of the case 12 from the insertion port 16, the end 64 on the rear end side of the longitudinal positioning portion 54 coincides with the cutout position 19 of the cutout portion 18 of the case 12. The separator 40 is positioned in the longitudinal direction so as to stop the insertion. Accordingly, the end 64 on the rear end side of the longitudinal positioning portion 54 is a substantial longitudinal positioning surface.

  Although the dimension of the separator 40 can be determined by the specifications of the temperature measuring element 20 and the lead wires 32 and 33, an example is as follows. The size of the temperature measuring element 20 is about 0.8 to 1 mm, the maximum dimension in the width direction of the inner surface of the case 12 facing the inner space 14 is about 3.0 to 3.5 mm, and the maximum dimension in the height direction. The total length in the longitudinal direction of the separator 40 is about 15 to 17 mm, the height of the height direction positioning portion 50 is the height of the separator 40 {(maximum dimension in the height direction of the opposing inner surface). − (About 0.1 to 0.5 mm)}, the interval dimension between the side surfaces 62 and 63 of the width direction positioning portions 52 and 53 is set to {(maximum dimension in the width direction of the opposed inner side surface) − ( About 0.1 to 0.5 mm)}.

  As the separator 40, as in the case 12, a separator molded into a predetermined shape using an appropriate resin material can be used. As the molding method, injection molding can be used, and as the resin material, for example, epoxy resin, polyphenylene sulfide (PPS) resin, or the like can be used as a resin suitable for injection molding.

  5 to 7 are diagrams summarizing the positioning function of the separator 40. FIG. FIG. 5 shows the width direction positioning function, FIG. 6 shows the height direction positioning function, and FIG. 7 shows the longitudinal direction positioning function. In these drawings, (a) shows the positioning surface of the separator 40, and (b) shows the positioning with the case 12.

  FIG. 5 is a diagram illustrating a width direction positioning function. Here, the side surfaces 62 and 63 of the width direction positioning portions 52 and 53 of the separator 40 are used. The side surfaces 62 and 63 are in contact with the inner side surfaces 72 and 73 of the internal space 14 of the case 12. FIG. 5 shows that positioning is performed in the contact states 62 and 72 and the contact states 63 and 73. The contact is performed with a slight gap amount. As a result, the separator 40 can be smoothly inserted into the internal space 14, and an appropriate positioning accuracy can be ensured.

  FIG. 6 is a diagram illustrating a height direction positioning function. Here, the top part 60 of the height direction positioning part 50 of the separator 40 is used. The top 60 contacts the inner side surface 70 of the internal space 14 of the case 12. FIG. 6 shows that positioning is performed in the contact state 60/70. The contact is performed with a slight gap amount. As a result, the separator 40 can be smoothly inserted into the internal space 14, and an appropriate positioning accuracy can be ensured.

  FIG. 7 is a diagram illustrating a function of longitudinal positioning. Here, the end portion 64 on the rear end side of the longitudinal positioning portion 54 of the separator 40 is used. The longitudinal direction of the separator 40 is a direction in which the separator 40 extends along the longitudinal direction of the case 12. Here, when the separator 40 is inserted into the internal space 14 of the case 12, the insertion is stopped when the position of the end portion 64 on the rear end side coincides with the cutout position 19 of the cutout portion 18 of the case 12. Thus, the longitudinal positioning of the separator 40 with respect to the case 12 is accurately performed. FIG. 7 shows that positioning is performed in the aligned states 64 and 19.

  Thus, the three-dimensional positioning of the separator 40 with respect to the case 12 can be accurately performed using the height direction positioning portion 50, the width direction positioning portions 52 and 53, and the longitudinal direction positioning portion 54 of the separator 40. Thereby, the three-dimensional positioning with respect to case 12 of the temperature measuring element 20 positioned and mounted on the separator 40 can be performed accurately, and the temperature measuring accuracy of the temperature sensor 10 is improved.

  FIG. 8 is a diagram showing examples of some forms of separators in the temperature sensor 10. (A) is a figure which shows what was demonstrated in FIGS. 1-7 as a basic form, (b) is a figure which shows the other form of a longitudinal direction positioning part, (c) is the other form of the width method positioning part (D) is a figure which shows another form of the width direction positioning part and the height direction positioning part. In these drawings, the left side is a top view of the separator, and the right side is a side view of the separator.

  FIG. 8A shows the separator 40 described in FIGS. 1 to 7 as a basic form, and thus detailed description thereof is omitted. The separator 80 shown in FIG. 8B has a bent portion 55 further on the rear end side from the rear end side end portion 64 which is the case opening side end portion as a longitudinal direction positioning portion as compared with FIG. Is. The bent portion 55 is bent in a direction in which the bent portion 55 is suspended from the cutout portion 18 of the case 12. Therefore, when the separator 80 is inserted into the internal space 14 of the case 12, the insertion is stopped at a position where the bent portion 55 abuts against the notch portion 18 of the case 12 and is suspended. Thereby, positioning in the longitudinal direction becomes simpler and more accurate than the separator 40.

  The separator 82 shown in FIG. 8C is obtained by moving the position where the width direction positioning portions 84 and 85 are provided to the tip side in the longitudinal direction as compared with FIG. Similarly, in the separator 86 shown in FIG. 8D, the position where the width direction positioning portions 88 and 89 are provided is moved to the tip side along the longitudinal direction as compared with FIG. ), The width direction positioning portions 88 and 89 are provided slightly on the rear end side, and the shapes thereof are also slightly different. Moreover, the length along the longitudinal direction of the height direction positioning part 90 is set slightly short.

  Thus, the position where the width direction positioning portion is provided may be any position along the longitudinal direction. Although not shown in FIG. 8, the width direction positioning portion and the height direction positioning portion may be located at the same position along the longitudinal direction. Further, the shape of the width direction positioning portion may be a shape other than the trapezoidal airfoil described with reference to FIGS. 1 to 7 as long as the contact is not hindered. As long as there is no problem in positioning, the contact may be a line contact, a line contact, or a point contact. Further, the length dimension along the longitudinal direction of the height direction positioning portion may be appropriately changed as long as it does not hinder the contact.
