Summary of the Invention

Problems to be Solved by the Invention

[0004] The durability of the sensor device is affected by the reliability of the welding applied to the joint between the component terminal of the detection module and the metal terminal. Therefore, it is important to enhance the reliability of the resistance welding joint applied to the joint portion. In conventional insert molded products for metal terminals, resistance welding is used, in which the joint portion of the metal terminal of the insert molded product and the component terminal of the detection module are overlapped, and a welding current is passed through them while they are sandwiched between welding electrodes, causing the metal to melt and diffuse due to resistance heating. During welding, the temperature of the welding electrode also rises, causing the contact area of ​​the resin body of the insert molded product that is in contact with the welding electrode to melt, resulting in resin adhering to the welding electrode and a problem of reduced welding reliability in continuous welding operations. To address this problem, one method is to increase the surface area of ​​the joint portion of the metal terminal so that the entire tip surface of the welding electrode is in contact with the metal terminal, but this increases the volume of the joint portion and thus the heat capacity, resulting in the problem of requiring a large amount of welding energy for joining. This invention aims to address these issues by preventing welding electrode contamination due to resin melting during resistance welding in insert molded products for metal terminals, and by improving welding reliability in continuous welding operations. [Means for solving the problem]

[0008] Embodiment 1. An insert molded product for a metal terminal according to Embodiment 1 of the present application will be described with reference to Figures 1 to 5. Figure 1 shows the metal terminal 1 of the insert molded product for a metal terminal according to Embodiment 1. The metal terminal 1 is a flat metal terminal, and as shown in Figure 2A, it is integrally molded and embedded in the resin body 2 to become an insert molded product for a metal terminal. The joint portion 1b, which is joined to other component terminals, is provided on the surface of the terminal portion 1a, which is the tip of the metal terminal 1. When viewed from the opposite back side, it looks like Figure 2B, and the back surface of the terminal portion 1a can be seen through the opening 2a for inserting a welding electrode during welding. Figure 3 shows a cross-section of the insert molded product for a metal terminal cut at the terminal portion 1a, where the terminal portion 1a, which is the tip of the metal terminal 1, is supported at its outer edge by the protruding portion 2b of the resin body 2.

[0009] Figure 4 is a cross-sectional perspective view showing the state immediately before welding the component terminal 3a of the detection module 3 to the terminal portion 1a of the metal terminal insert molded product. It shows that the terminal portion 1a and the component terminal 3a are sandwiched between a pair of welding electrodes 4, and the joint portion 1b of the terminal portion 1a and the component terminal 3a are welded at the welding area 5 by resistance welding. Next, as shown in Figure 5, the component terminal 3a of the detection module 3 and the terminal portion 1a of the metal terminal 1 of the insert molded product are superimposed, sandwiched from both sides by welding electrodes 4, and current for welding is passed through them, resistance welding is performed at the welding portion 5, and they are joined at the joint portion 1b. During resistance welding, the terminal portion 1a of the metal terminal 1 and the welding electrode 4 are in contact, but a separation distance is maintained between the surface of the welding electrode 4 and the protruding portion 2b of the resin body 2 that faces it. Because the thickness of the terminal portion 1a is greater than the thickness of the protruding portion 2b of the resin body 2 that supports the outer edge of the terminal portion 1a, a separation structure is formed that separates the welding electrode 4 and the resin body 2.

[0010] Because the separation distance between the welding electrode 4 and the resin body 2 is maintained in this way, resin adhesion to the welding electrode 4 can be avoided even when the welding electrode 4 becomes hot during welding, and welding reliability can be ensured in continuous welding operations.

[0011] Embodiment 2. An insert molded product for a metal terminal according to Embodiment 2 of the present application will be described with reference to Figures 6 to 9. Note that parts corresponding to the components of Embodiment 1 and Embodiment 2 are indicated by the same reference numerals, and detailed descriptions are omitted. Figure 6 shows a metal terminal 1 used in Embodiment 2, where a central part 1c including a joint 1b is located at the center of the terminal portion 1a, and a peripheral portion 1d is provided to surround it. The central part 1c is connected to the other parts of the metal terminal 1, and a gap 1e is formed between the central part 1c and the peripheral portion 1d. When insert molding a metal terminal 1 with a resin body 2, the terminal portion 1a is sandwiched by the molding die, making it easy to create an insert molded product in which there is no resin (empty space) in the gap 1e between the central part 1c and the surrounding peripheral part 1d.

[0012] Figure 7A shows the appearance of the insert molded product for the metal terminal using the metal terminal 1, and in the view from the back in Figure 7B, the gap 1e of the terminal portion 1a is visible through the opening 2a of the resin body 2. Here, the opening 2a is shown as an example of a rectangular shape that matches the outer edge of the terminal portion 1a. Figure 8 is a perspective view showing a cross-section of the insert molded product for the metal terminal of this embodiment 2 cut at the terminal portion 1a. Figure 9 is a cross-sectional view showing the state during welding, where the welding electrode 4 is in contact with the central part 1c of the terminal portion 1a, and a separation structure is formed between the welding electrode 4 and the resin body 2, separated by a gap 1e and a peripheral portion 1d.

[0013] Because the separation between the welding electrode 4 and the resin body 2 is maintained in this way, resin adhesion to the welding electrode 4 can be avoided even when the welding electrode 4 becomes hot during welding, and welding reliability can be ensured in continuous welding operations. Furthermore, since the terminal portion 1a of the metal terminal 1 that contacts the surface of the welding electrode 4 is limited to the central portion 1c, the volume of the joint portion 1b is also reduced, resulting in a smaller heat capacity, which makes it possible to reduce the welding energy during joining. Furthermore, since the resin body 2 has an opening 2a that not only supports the terminal portion 1a at its outer edge but also supports the peripheral portion 1d from below, the strength to support the metal terminal 1 can be improved.

[0014] Embodiment 3. An insert molded product for a metal terminal according to Embodiment 3 of the present application will be described with reference to Figures 10A to 12. Note that parts corresponding to the components of Embodiments 1 and 2 are indicated by the same reference numerals, and detailed descriptions are omitted. The shape of the metal terminal 1 in Embodiment 3 is the same as the metal terminal shown in Embodiment 2, which is shown in Figure 6. Figure 10A shows the appearance of the insert molded product for the metal terminal using this metal terminal 1, and is the same as Figure 7A in Embodiment 2. On the other hand, the appearance from the back side in Figure 10B shows that the opening 2a is a round shape with the terminal portion 1a exposed, and is a different structure from the resin body 2 in Embodiment 2.

[0015] Figure 11 is a perspective view showing a cross-section of the insert molded metal terminal product of this third embodiment, cut at the terminal portion 1a. In Figure 11, the peripheral portion 1d of the terminal portion 1a of the metal terminal 1 and the protruding portion 2b of the resin body 2 are in contact. When insert molding the metal terminal 1, the outer edge of the peripheral portion 1d surrounding the terminal portion 1a becomes the sealing portion 2c of the resin body 2. Because the thickness of the peripheral portion 1d is the same as the thickness of the protruding portion 2b of the resin body 2 that supports the outer edge of the terminal portion 1a, the entire surface of the peripheral portion 1d surrounding the terminal portion 1a can be pressed down by the mold during insert molding of the metal terminal 1. In this way, the metal terminal 1 is not affected by misalignment during insert molding, and the resin can be easily sealed by suppressing the resin from creeping up into the joint portion 1b, the center portion 1c, and the gap 1e. Figure 12 is a cross-sectional view showing the state during welding, where the welding electrode 4 is in contact with the central part 1c of the terminal portion 1a, and a separation structure is formed between the welding electrode 4 and the resin body 2, separated by a gap 1e and a peripheral portion 1d. Furthermore, by providing an overhanging portion 2b of the resin body 2, a large separation distance can be maintained between the welding electrode 4 and the resin body 2.

[0016] Because the separation between the welding electrode 4 and the resin body 2 is maintained in this way, resin adhesion to the welding electrode 4 can be avoided even when the welding electrode 4 becomes hot during welding, and welding reliability can be ensured in continuous welding operations. Furthermore, since the terminal portion 1a of the metal terminal 1 that contacts the surface of the welding electrode 4 is limited to the central portion 1c, the volume of the joint portion 1b is also reduced, resulting in a smaller heat capacity, which makes it possible to reduce the welding energy during joining.

[0017] Embodiment 4. An insert molded product for a metal terminal according to Embodiment 4 of the present application will be described with reference to Figures 13A to 16. Note that parts corresponding to the components of Embodiments 1 to 3 are indicated by the same reference numerals, and detailed descriptions are omitted. Figure 13A shows the external appearance of the metal terminal 1 in Embodiment 4, Figure 13B shows the external appearance from the opposite side, and Figure 13C is a perspective view showing a cross-section of the terminal portion 1a cut in the middle. Thus, in Embodiment 4, the metal terminal 1 has a terminal portion 1a with its joint portion 1b as the front surface, a central part 1c separated by a groove 1f on the back surface, and a peripheral portion 1d surrounding it. By configuring the terminal portion 1a of the metal terminal 1 in this way, the rigidity of the terminal portion 1a can be increased compared to the metal terminal 1 in Embodiments 2 and 3, in which a gap 1e is provided in the terminal portion 1a, which has the advantage of making the metal terminal 1 easier to handle.

[0018] Figure 14A shows the appearance of the insert molded product for the metal terminal using this metal terminal 1, and in the view from the back in Figure 14B, the groove 1f of the terminal portion 1a is visible through the opening 2a of the resin body 2. Figure 15 is a perspective view showing a cross-section of the insert molded product for the metal terminal of this embodiment 4 cut at the terminal portion 1a. Figure 16 is a cross-sectional view showing the state during welding, where the welding electrode 4 is in contact with the central part 1c of the terminal portion 1a, and a separation structure is formed between the welding electrode 4 and the resin body 2, separated by the space of the groove 1f and the peripheral portion 1d.

[0019] Because the separation between the welding electrode 4 and the resin body 2 is maintained in this way, resin adhesion to the welding electrode 4 can be avoided even when the welding electrode 4 becomes hot during welding, and welding reliability can be ensured in continuous welding operations. Furthermore, since the terminal portion 1a of the metal terminal 1 that contacts the surface of the welding electrode 4 is limited to the central portion 1c separated by the groove 1f, the volume of the joint portion 1b is also reduced, and the heat capacity is reduced, making it possible to reduce the welding energy during joining.

[0020] Embodiment 5. An insert molded product for a metal terminal according to Embodiment 4 of the present application will be described with reference to Figures 17A to 21. Note that parts corresponding to the components of Embodiments 1 to 4 are indicated by the same reference numerals, and detailed descriptions are omitted. Figure 17A shows the external appearance of the metal terminal 1 in Embodiment 4, and Figure 17B shows the external appearance viewed from the opposite side. The metal terminal 1 in Embodiment 5 is characterized in that the thickness of the central part 1c of the terminal portion 1a is smaller than the thickness of the peripheral portion 1d surrounding it. Figure 18A shows the appearance of the insert molded product for the metal terminal using this metal terminal 1, and in the view from the back in Figure 18B, the gap 1e of the terminal portion 1a is visible through the opening 2a of the resin body 2. Figure 19 is a perspective view showing a cross-section of the insert molded product for the metal terminal of this embodiment 5 cut at the terminal portion 1a.

[0021] Figure 20 is a cross-sectional view showing the state when insert molding the metal terminal 1 in Embodiment 5. As shown in Figure 20, insert molding is performed by sandwiching the metal terminal 1 between molds 6a and 6b from above and below and injecting resin. At that time, the thickness of the central part 1c of the terminal part 1a of the metal terminal 1 is smaller than the thickness of the peripheral part 1d surrounding it, which ensures reliable contact between the molding dies. As the load tends to concentrate on the peripheral part 1d during insert molding, the effect of the sealing part 2c of the resin body 2 described in Embodiment 3 becomes stronger. In other words, the resin can be easily sealed without being affected by the displacement of the metal terminal 1 during insert molding, and by suppressing the creeping of the resin into the joint part 1b, the central part 1c, and the gap 1e. Figure 21 is a cross-sectional view showing the state during welding. The welding electrode 4 is in contact with the central part 1c of the terminal portion 1a, and a separation structure is formed between the welding electrode 4 and the resin body 2, separated by a gap 1e and a peripheral portion 1d. Furthermore, by providing an overhanging portion 2b of the resin body 2, a large separation distance can be maintained between the welding electrode 4 and the resin body 2.

[0022] Because the separation between the welding electrode 4 and the resin body 2 is maintained in this way, resin adhesion to the welding electrode 4 can be avoided even when the welding electrode 4 becomes hot during welding, and welding reliability can be ensured in continuous welding operations. Furthermore, since the terminal portion 1a of the metal terminal 1 that contacts the surface of the welding electrode 4 is limited to the thinly formed central portion 1c, the volume of the joint portion 1b is also reduced, resulting in a smaller heat capacity, which makes it possible to reduce the welding energy during joining.

[0023] Embodiment 6. An insert molded product for a metal terminal according to Embodiment 6 of the present application will be described with reference to Figures 22 to 24. Note that parts corresponding to the components of Embodiments 1 to 5 are indicated by the same reference numerals, and detailed descriptions are omitted. Figure 22 shows a metal terminal 1 used in Embodiment 6, characterized by the circular planar shape of the terminal portion 1a. In Figure 22, there is a central part 1c containing a joint portion 1b at its center, and a peripheral portion 1d is provided to surround it. The central part 1c is connected to other parts of the metal terminal 1, and a gap 1e is formed between the central part 1c and the peripheral portion 1d. Since resistance welding joins are joined by forming a circular molten portion during joining, the volume of the welded portion 5 can be reduced by providing the joint portion 1b in the circular central part 1c.

[0024] Figure 23A shows the appearance of the insert molded product for the metal terminal using this metal terminal 1, and in the view from the back in Figure 23B, the gap 1e of the terminal portion 1a is visible through the opening 2a of the resin body 2. Figure 24 is a perspective view showing a cross-section of the insert molded product for the metal terminal of this embodiment 6 cut at the terminal portion 1a. Although not shown in the figures, the welding configuration in Embodiment 6 is the same as that in Figure 12, a cross-sectional view showing the state during welding in Embodiment 3. That is, the welding electrode 4 comes into contact with the central part 1c of the terminal portion 1a, and a separation structure is formed between the welding electrode 4 and the resin body 2, separated by the gap 1e and the peripheral portion 1d. Furthermore, the protruding portion 2b of the resin body 2 allows for a large separation distance to be maintained between the welding electrode 4 and the resin body 2.

[0025] Because the separation between the welding electrode 4 and the resin body 2 is maintained in this way, resin adhesion to the welding electrode 4 can be avoided even when the welding electrode 4 becomes hot during welding, and welding reliability can be ensured in continuous welding operations. Furthermore, since the terminal portion 1a of the metal terminal 1 that contacts the surface of the welding electrode 4 is limited to the central portion 1c which is formed in a circular shape to match the shape of the weld 5, the volume of the joint portion 1b is also reduced, and the heat capacity is reduced, making it possible to reduce the welding energy during joining.

[0026] Embodiment 7. An insert molded product for a metal terminal according to Embodiment 7 of the present application will be described with reference to Figure 25. Note that parts corresponding to the components of Embodiments 1 to 6 are indicated by the same reference numerals, and detailed descriptions are omitted. Figure 25 is a perspective view showing the appearance of an insert molded product for a metal terminal according to Embodiment 7. In Figure 25, the metal terminal 1 is provided with the same circular terminal portion 1a as shown in Embodiment 6. In Embodiment 7, a projection 1g is provided at the joint portion 1b, which is the center of the central part 1c of the terminal portion 1a. In this way, by providing a projection 1g on the joint portion 1b of the terminal portion 1a, the welding current during resistance welding is concentrated on the projection 1g, making it easier to stably form the welded portion 5 and improving welding reliability. Furthermore, this projection 1g can also be applied to other embodiments, and similar effects can be obtained by providing the projection 1g on the joint portion 1b.

[0027] In the examples shown in Embodiments 1 to 7 of this application, the terminal portion 1a provided on the metal terminal 1 was a single unit. However, there are cases where multiple detection modules are joined to the metal terminal 1. In such cases, it is possible to provide multiple terminal portions 1a on the metal terminal 1, which is insert-molded into the insert-molded product for the metal terminal, and multiple joining portions 1b that are joined to the component terminals 3a of the multiple detection modules 3. Even in such cases, it is possible to provide the configuration shown in Embodiments 1 to 7 of this application, and similar effects can be obtained.
