[0009] First, embodiments of this disclosure will be described. (1) The connector disclosed herein comprises: a terminal; a resin portion integrally formed with the terminal by molding and disposed in the opening such that the terminal is located in an opening formed in the connector mounting counterpart; a plate integrally formed with the terminal in the resin portion by molding, such that surface pressure of a sealing member is ensured to prevent water from flowing between the resin portion and the connector mounting counterpart in the opening; and a three-dimensional insulating portion disposed in the plate to insulate the terminal from the plate.

[0010] According to this configuration, because a three-dimensional insulating portion is provided between the terminal and the board, even if water seeps in from the interface between the board and the resin portion when a crack forms in the resin portion from the terminal to the board, the insulating portion can prevent water from reaching the crack. Therefore, it is less likely that water seeping into the connector from the interface between the resin portion and the board will reach the terminal through the crack. Thus, short circuits between the terminal and the board caused by water seeping in from the interface between the resin portion and the board are less likely to occur. Therefore, the insulation reliability of the connector can be improved.

[0011] (2) In (1) above, a plurality of terminals are provided, and the insulating portion has a shape in which a single component faces the plurality of terminals. According to this configuration, even if there are multiple terminals, the insulating portion is a single component, which helps to simplify the structure of the connector.

[0012] (3) In (1) or (2) above, a positioning part is provided between the plate and the insulating part to position the insulating part on the plate. According to this configuration, the insulating part can be fixed to the plate by means of the positioning part, so it is not easy for the position of the insulating part to shift.

[0013] (4) In any of (1) to (3) above, the terminal is a live wire terminal, and the insulating portion has a thick-walled portion and a thin-walled portion with shapes corresponding to the shapes of the opposing live wire terminals. According to this configuration, when the live wire terminal has a stepped portion, for example, a stepped shape, the thick-walled portion and the thin-walled portion corresponding to the stepped portion are formed in the insulating portion. Therefore, by keeping the distance between the live wire terminal and the insulating portion constant, the weight of the resin portion in this part can be reduced. Therefore, the thickness of the resin portion formed between the live wire terminal and the insulating portion can be reduced, thus suppressing the formation of pores or shrinkage cavities in this part.

[0014] (5) In any of (1) to (4) above, the resin portion has an annular portion with a shape corresponding to the opening, the terminal is configured to protrude to the inside of the annular portion, and the plate has: a plate body that presses the sealing member when fixed to the connector mounting counterpart; and a plate hole formed in the plate body with a shape corresponding to the opening, the insulating portion being disposed along the periphery of the plate hole. According to this configuration, when the resin portion has an annular shape, the insulating portion can be disposed along the annulus. Therefore, countermeasures can be effectively taken against short circuits caused by water seeping in from the interface between the resin portion and the plate.

[0015] (6) In (5) above, the resin part has a terminal mounting part on the side of the annular part for receiving the terminal, and the insulating part is disposed between the terminal received in the terminal mounting part and the plate. According to this configuration, for connectors where the terminal and the plate are disposed close together, the insulating part provided between the terminal and the plate can be used to counteract short circuits caused by water seeping in from the interface between the resin part and the plate.

[0016] (7) In any of (1) to (6) above, the insulating portion is formed on the plate by a single molding process, and the resin portion is formed by a secondary molding process in which the terminal and the plate are integrally formed using resin. According to this configuration, the insulating portion is formed on the plate by molding, and furthermore, the terminal and the plate are also integrally formed by molding. Therefore, the processes for both can be identical, thus simplifying manufacturing.

[0017] (8) In any of (1) to (6) above, the insulating part is formed from a component separate from the plate and is integrated with the plate by assembly. According to this configuration, a plate having an insulating part can be manufactured by a simple method of mounting the insulating part manufactured in other processes onto the plate.

[0018] (Details of the embodiments disclosed herein) Specific examples of this disclosure are described below with reference to the accompanying drawings. It should be noted that the invention is not limited to these examples, but is intended to include all modifications within the meaning and scope equivalent to the claims, as indicated by the claims. In the drawings, for ease of description, some parts of the structure are sometimes exaggerated or simplified. Furthermore, the dimensional ratios of the various parts may sometimes differ from the actual values.

[0019] (Connector 1) like Figure 1 As shown, connector 1 includes terminals 2, resin portion 3, and plate 4. Connector 1 is a structure in which terminals 2 and plate 4 are integrally formed with resin portion 3 by molding terminals 2 and plate 4. Molding is, for example, a molding method that manufactures terminals 2, resin portion 3, and plate 4 into an integral part by placing terminals 2 and plate 4 in a mold and injecting resin into the mold to cure it.

[0020] Connector 1 is mounted and fixed to connector mounting partner 5, which has electrical terminals (not shown) for connection with terminal 2. Connector mounting partner 5 is, for example, a hollow housing containing predetermined electrical components (not shown). Connector 1 is fixed to connector mounting partner 5 such that the end of terminal 2 is positioned at an opening 6 formed in connector mounting partner 5. In this example, multiple (six in this example) terminals 2 are provided.

[0021] (Resin Part 3) like Figures 1 to 3 As shown, the resin portion 3 has an annular portion 8 with a shape corresponding to the opening portion 6. In this example, the annular portion 8 has a hole 9 formed in a manner communicating with the opening portion 6. The resin portion 3 has a terminal mounting portion 10 on the side of the annular portion 8 for receiving terminals 2. In this example, multiple terminal mounting portions 10 are provided corresponding to each terminal 2 (six in this example).

[0022] like Figure 1 As shown, connector 1 is mounted and fixed to connector mounting partner 5 such that the sealing member 11 is positioned between resin part 3 and connector mounting partner 5. Sealing member 11 is, for example, an annular rubber gasket. A sealing receiving recess 12 (see reference 5) is formed on the back side of resin part 3 for positioning the sealing member 11 within resin part 3. Figure 2 The sealing recess 12 is formed in an annular shape to surround the hole 9.

[0023] (Panel 4) like Figure 4As shown, plate 4 has: a plate body 14 that presses against the sealing member 11 when fixed to the connector mounting mat 5; and a plate hole 15 formed in the plate body 14 in a shape corresponding to the opening 6. Plate 4 is mounted to the connector mounting mat 5 in a state where the sealing member 11 disposed between plate 4 and connector mounting mat 5 is pressed relatively strongly by the plate body 14 to ensure surface pressure. Plate 4 is metallic.

[0024] like Figure 1 As shown, multiple holes 17 are formed on both sides of the plate body 14. The holes 17 are used to insert fasteners 16 (only one is shown) such as bolts and screws to fix the plate 4 to the connector mounting counterpart 5. By inserting the shaft of the fastener 16 into the holes 17 formed on both sides of the plate body 14 and fastening the shaft of the fastener 16 to the fastened part 18 of the connector mounting counterpart 5, the plate 4 is fixed to the connector mounting counterpart 5.

[0025] like Figure 4 As shown, a through hole 19 is formed in the plate 4, and resin for connecting the resin parts on the front and back sides of the plate is disposed in the through hole 19. Multiple through holes 19 are arranged along the periphery of the plate hole 15 (six in total in this example). The resin parts 3 are securely fixed to the plate 4 by being connected to the resin parts on the front and back sides of the plate through the through holes 19.

[0026] (Terminal 2) like Figure 5 and Figure 6 As shown, terminal 2 is a wire terminal 22 with terminal 2 fixed to the end of wire 21. Wire 21 has a core wire 23 and an insulating covering portion 24 that surrounds the core wire 23. The core wire 23 can be, for example, a busbar or stranded wire. The core wire 23 protrudes a predetermined amount from the end of the insulating covering portion 24. A heat shrink tubing 25 is installed on the outer periphery of the insulating covering portion 24 and at the entrance position of the terminal mounting portion 10. The heat shrink tubing 25 ensures the water-tightness of the interface between the resin portion 3 and the insulating covering portion 24.

[0027] Terminal 2 has: a wire connection portion 26, to which the core wire 23 of the wire 21 is connected; and a contact portion 27, which is fixed to the electrical terminal (not shown) of the connector mounting counterpart 5. The contact portion 27 is formed as a plate-shaped conductor that has been bent multiple times. Specifically, the contact portion 27 has: a base end portion 28, which is formed to extend in an inclined direction from the wire connection portion 26; a middle portion 29, which is bent downward at approximately 90 degrees from the end of the base end portion 28; and an end portion 30, which is bent upward at approximately 90 degrees from the end of the middle portion 29. Thus, terminal 2 is arranged such that the axes of the wire connection portion 26 and the end portion 30 do not overlap when viewed from above. Terminal 2 is configured to expose inside the annular portion 8 of the resin portion 3. Specifically, a portion of the contact portion 27 of terminal 2 is configured to expose inside the annular portion 8.

[0028] (Insulation part 32) like Figure 5 and Figure 7 As shown, a three-dimensional insulating portion 32 is provided on the plate 4 to insulate the terminal 2 from the plate 4. The insulating portion 32 is configured, for example, to prevent cracks (crazing) 33 from forming in the resin portion 3 (see reference). Figure 11 This also ensures insulation between terminal 2 and plate 4. The three-dimensional shape of the insulating part 32 refers to a shape having a certain thickness, for example. The insulating part 32 is made of resin, for example.

[0029] In this example, the insulating portion 32 is arranged along the periphery of the plate hole 15. The insulating portion 32 has, for example, a shape in which a single component faces multiple terminals 2. Specifically, the insulating portion 32 is formed in a strip shape in such a way that it faces multiple terminals 2.

[0030] As the insulating part 32, a one-molded article can be cited as an example. In this case, the insulating part 32 is formed on the plate 4 by one-molding. In addition, the resin part 3 is formed by a two-molding process that integrally forms the terminal 2 and the plate 4. That is, the plate 4 having the insulating part 32 is formed by one-molding, and the plate 4 and the terminal 2 are integrally formed by two-molding.

[0031] As an insulating part 32, for example, a separate component that is subsequently mounted on the plate 4 can be cited. In this case, the insulating part 32 is integrated with the plate 4 through assembly. That is, the insulating part 32 is formed in other manufacturing processes, and the plate 4 having the insulating part 32 is manufactured by assembling the insulating part 32 onto the plate 4.

[0032] like Figure 8 As shown, the insulating portion 32 is disposed, for example, between the terminal 2 housed in the terminal mounting portion 10 and the plate 4. The insulating portion 32 is mounted on the plate 4 and is arranged opposite to the terminal 2. In this example, the insulating portion 32 is arranged opposite to the wire connection portion 26 of the terminal 2. The insulating portion 32 is arranged so that it is entirely hidden inside the resin portion 3.

[0033] (Stepped shape of insulation part 32) like Figure 8 As shown, the live wire terminal 22 is formed with a stepped portion 35 at the point where the core wire 23 is exposed from the insulating cover portion 24. In this example, the insulating portion 32 is formed with a stepped shape corresponding to the stepped portion 35 of the live wire terminal 22. Specifically, the insulating portion 32 has a thick-walled portion 36 opposite to the wire connection portion 26 on which the core wire 23 is fixed, and a thin-walled portion 37 opposite to the insulating cover portion 24. Thus, the insulating portion 32 is formed with a stepped shape having a thick-walled portion 36 and a thin-walled portion 37 in a manner corresponding to the shape of the oppositely arranged live wire terminal 22.

[0034] like Figure 9 As shown, the thick-walled portion 36 is formed, for example, along the plate hole 15 of the plate 4, thereby forming a shape that connects a plurality of thin-walled portions 37. Specifically, the thick-walled portion 36 has a protruding portion 36a that protrudes in the direction of the thin-walled portion 37, and a concave portion 36b that avoids the through hole 19. The protruding portion 36a is formed for each thin-walled portion 37. The concave portion 36b is formed for each through hole 19. The thin-walled portion 37 is formed lower than the thick-walled portion 36 and extends to a position disposed at the end edge of the plate 4.

[0035] (Positioning section 39) like Figure 10 As shown, a positioning portion 39 is provided between the plate 4 and the insulating portion 32 to position the insulating portion 32 on the plate 4. The positioning portion 39, for example, has a plurality of positioning protrusions 40 formed on the insulating portion 32 and a plurality of positioning holes 41 formed on the plate 4. The positioning protrusions 40 are arranged along the width direction on the back surface of the insulating portion 32. The positioning holes 41 are provided through the plate 4 in a manner corresponding to each positioning protrusion 40.

[0036] (The role of the implementation method) Next, the function of connector 1 in this embodiment will be explained. like Figure 11 As shown, in the connector 1 having a resin part 3, for example, it is possible for a crack (crazing) 33 to be generated in the resin part 3, extending from the terminal 2 to the plate 4. In the case of a crack 33 of this shape being generated in the resin part 3, if water seeps into the interior from the interface between the resin part 3 and the plate 4 and reaches the crack 33, the water may reach the terminal 2, causing a short circuit between the terminal 2 and the plate 4.

[0037] In this example, because an insulating portion 32 is provided on the plate 4, even if water seeps in from the interface between the resin portion 3 and the plate 4, the insulating portion 32 can block the water from reaching the crack 33. That is, water that has seeped into the interior of the resin portion 3 is unlikely to reach the terminal 2. Therefore, the insulation between the terminal 2 and the plate 4 can be ensured.

[0038] Furthermore, in this example, because the insulating portion 32 is formed in a three-dimensional shape, the weight of the resin portion 3 can be reduced accordingly. Specifically, because the insulating portion 32 is shaped to have a thick-walled portion 36 and a thin-walled portion 37, consistent with the shape of the stepped portion 35 of the wire terminal 22, the weight of the insulating portion 32 can be reduced in this part. Therefore, when molding the connector 1, which integrates the terminal 2 and the plate 4 with resin, it is also possible to prevent the formation of pores or shrinkage cavities in the portion of the resin portion 3 opposite to the wire terminal 22.

[0039] (Effects of the implementation method) The connector 1 according to the above embodiment can achieve the following effects. (1) Connector 1 includes a terminal 2, a resin portion 3, and a plate 4. The resin portion 3 is integrally formed with the terminal 2 by molding, and is disposed in the opening 6 such that the terminal 2 is located in the opening 6 formed in the connector mounting counterpart 5. The plate 4 is integrally formed with the terminal 2 in the resin portion 3 by molding, thereby ensuring the surface pressure of the sealing member 11 that prevents water from flowing between the resin portion 3 and the connector mounting counterpart 5 in the opening 6. An insulating portion 32 with a three-dimensional shape is provided on the plate 4 to insulate the terminal 2 and the plate 4.

[0040] According to this configuration, because a three-dimensional insulating portion 32 is provided between the terminal 2 and the plate 4, when a crack 33 is formed in the resin portion 3 from the terminal 2 to the plate 4, even if water seeps in from the interface between the resin portion 3 and the plate 4, the insulating portion 32 can prevent water from reaching the crack 33. Therefore, it is less likely that water seeping into the interior of the connector 1 from the interface between the resin portion 3 and the plate 4 will reach the terminal 2 via the crack 33. Thus, short circuits between the terminal 2 and the plate 4 caused by water seeping in from the interface between the resin portion 3 and the plate 4 are less likely to occur. Therefore, the insulation reliability of the connector 1 can be improved.

[0041] (2) Multiple terminals 2 are provided. The insulating part 32 has a shape in which multiple terminals 2 are opposed to each other as a single component. According to this configuration, even if there are multiple terminals 2, the insulating part 32 is a single component, which helps to simplify the structure of the connector 1.

[0042] (3) A positioning part 39 is provided between the plate 4 and the insulating part 32 to position the insulating part 32 on the plate 4. According to this configuration, the insulating part 32 can be fixed to the plate 4 by means of the positioning part 39, so it is not easy for the position of the insulating part 32 to be offset.

[0043] (4) Terminal 2 is a live wire terminal 22. The insulating portion 32 has a thick-walled portion 36 and a thin-walled portion 37 with shapes corresponding to the shape of the oppositely arranged live wire terminal 22. According to this configuration, when the live wire terminal 22 has, for example, a stepped portion 35, the thick-walled portion 36 and the thin-walled portion 37 corresponding to the stepped portion 35 are formed in the insulating portion 32. Therefore, by keeping the distance between the live wire terminal 22 and the insulating portion 32 constant, the weight of the resin portion 3 in this part can be reduced. Therefore, the thickness of the resin portion 3 formed between the live wire terminal 22 and the insulating portion 32 can be reduced, so the generation of pores or shrinkage cavities in this part can be suppressed.

[0044] (5) The resin part 3 has an annular part 8 with a shape corresponding to the opening 6. The terminal 2 is configured to protrude to the inside of the annular part 8. The plate 4 has: a plate body 14, which presses the sealing member 11 when fixed to the connector mounting counterpart 5; and a plate hole 15, which is formed in the plate body 14 with a shape corresponding to the opening 6. The insulating part 32 is arranged along the periphery of the plate hole 15. According to this configuration, when the resin part 3 has the shape of an annular part 8, the insulating part 32 can be arranged along the annulus. Therefore, countermeasures can be effectively taken against short circuits caused by water immersing from the interface between the resin part 3 and the plate 4.

[0045] (6) The resin part 3 has a terminal mounting part 10 for receiving the terminal 2 on the side of the annular part 8. An insulating part 32 is disposed between the terminal 2 received in the terminal mounting part 10 and the plate 4. According to this configuration, for the connector 1 where the terminal 2 and the plate 4 are disposed close together, the insulating part 32 disposed between the terminal 2 and the plate 4 can be used to counteract short circuits caused by water seeping in from the interface between the resin part 3 and the plate 4.

[0046] (7) The insulating part 32 is formed on the plate 4 by a single molding process. The resin part 3 is formed by a secondary molding process in which the terminal 2 and the plate 4 are integrated by using resin. According to this configuration, the insulating part 32 is formed on the plate 4 by molding, and furthermore, the terminal 2 and the plate 4 are also integrated by molding. Therefore, the processes for both can be made the same, which helps to simplify manufacturing.

[0047] (8) The insulating part 32 is formed from a component that is separate from the plate 4, and is integrated with the plate 4 by assembly. According to this configuration, the plate 4 having the insulating part 32 can be manufactured by a simple method of installing the insulating part 32, which is manufactured in other processes, onto the plate 4.

[0048] (Other implementation methods) It should be noted that this embodiment can be implemented with the following modifications. This embodiment and the following variations can be combined and implemented with each other within the scope of technical inconsistency.

[0049] The insulating portion 32 can also be formed covering the entire circumference of the plate hole 15. The insulating portion 32 is not limited to being formed only on the surface of the plate 4, but may also be formed on the back side.

[0050] The insulating portion 32 is not limited to being formed only on a part of the interface between the resin portion 3 and the plate 4, but may also be formed on the entire interface (including the entire interface). The insulating portion 32 is not limited to having a shape with a thick-walled portion 36 and a thin-walled portion 37, but may also have a shape with a uniform thickness.

[0051] The thick-walled portion 36 can also be formed in the form of each thin-walled portion 37. That is, the insulating portion 32 can also be formed in a shape that is separate for each terminal 2. The thin-walled portion 37 can also be formed in the same way as the thick-walled portion 36, with only one portion.

[0052] Terminal 2 is not limited to being disposed on the side of resin portion 3 (specifically annular portion 8), but may also be disposed on the upper part of resin portion 3 (specifically annular portion 8). The number of terminals 2 is not limited to multiple; it can also be one.

[0053] The resin part 3 may also be shaped without the hole 9. In this case, the resin part 3 is fixed to the connector mounting partner 5 in such a way that it closes the opening 6 of the connector mounting partner 5. When the plate 4 is fixed to the connector mounting counterpart 5 using the fastening part 16, the number of fastening parts 16 can also be appropriately changed to a number other than that in the embodiment.

[0054] The position of the hole 17 in plate 4 can also be changed to a position other than that in the embodiment. The structure for fixing plate 4 to connector mounting surface 5 is not limited to the structure using fastener 16. For example, a structure in which locking tab engages with protrusion can also be used.

[0055] As shown in the non-limiting embodiment, the plate 4 or the plate body 14 can have a surface direction that can be used as the XY plane and a thickness that can be used as the Z direction. Figure 3 As shown, the contact portion 27 of terminal 2 can be located inside the plate hole 15 of plate 4 and inside the hole portion 9 of resin portion 3 in the surface direction of plate 4. The plate hole 15 of plate 4 and the hole portion 9 of resin portion 3 are sometimes referred to as the terminal window of connector 1.

[0056] like Figure 8 As shown, the resin part 3 and the insulating part 32 can contact each other through a contact interface. The resin part 3 can be made of a first resin material, and the insulating part 32 can be made of a second resin material. The first resin material and the second resin material can be different or the same.

[0057] like Figure 5 As shown, the insulating portion 32 can be configured such that the thick-walled portion 36 of the insulating portion 32 covers the plurality of positioning holes 41 of the plate 4, and the insulating portion 32 does not cover the plurality of through holes 19 of the plate 4. The thick-walled portion 36 of the insulating portion 32 is sometimes referred to as a reinforcing resin portion having length and thickness that extends continuously along the edge of the hole 15. The plurality of thin-walled portions 37 of the insulating portion 32 can be discretely arranged at constant intervals, and each thin-walled portion 37 can extend in a direction away from the edge of the hole 15. Figure 9As shown, the discretely arranged plurality of thin-walled portions 37 may also have ends at locations away from the through hole 19 of the plate 4, for example, on the outer edge of the plate 4. The resin insulating portion 32, which is between the plate 4 (which may be metallic) and the resin portion 3 (which is not metallic), and is in direct contact with the resin portion 3, helps to reduce the peeling of the resin portion 3 from the plate 4 (which may be metallic).

[0058] In a non-limiting embodiment illustrated, the positioning protrusions 40 of the insulating portion 32 may enter the positioning holes 41 of the plate 4, and the lower surface of the insulating portion 32 and the upper surface of the plate 4 may directly contact each other, thereby achieving a watertight seal between the insulating portion 32 and the plate 4. The plurality of positioning protrusions 40 of the insulating portion 32 may also protrude downwards from the lower surface of the plurality of thick-walled portions 36 of the insulating portion 32. In a workpiece in which the insulating portion 32 and the plate 4 are integrated, the positioning holes 41 of the plate 4 are covered by the thick-walled portions 36 of the insulating portion 32, and the plurality of through holes 19 of the plate 4 are not covered by the insulating portion 32. This workpiece is provided to the molding process along with the wire terminal 22. By injecting a flowable resin material for forming the resin portion 3 into the plurality of through holes 19 of the plate 4 that are not covered by the insulating portion 32, a plurality of pin-shaped resin bridges are formed penetrating the plate 4.

[0059] like Figure 4 As shown, the plurality of through holes 19 and the plurality of positioning holes 41 of plate 4 can also be spaced equidistant from the edge of the hole 15 in the surface direction of plate 4. The through holes 19 and positioning holes 41 can also be arranged in a row, for example, along the edge of the hole 15. The through holes 19 and positioning holes 41 are sometimes referred to as a row of discrete through holes.

[0060] The connector 1 in the illustrated non-limiting embodiment can be a vehicle connector as described in Japanese Patent Application Publication No. 2013-222876 (Patent Document 1).
