[0010] This embodiment relates to a connector 1 used for electrical connection. Figure 1 and other figures define the mutually orthogonal front-rear, up-down, and left-right directions of the connector 1. The front-rear and left-right directions are parallel to a board 95 (Figure 7) on which the connector 1 is mounted. The up-down direction is perpendicular to the board 95. The left-right direction is the arrangement direction of the terminals 30 when there are multiple terminals 30. In this specification, the surface of each element facing forward is referred to as the "front side" and the surface facing backward is referred to as the "back side."

[0011] 1 to 6 show the overall structure of the connector 1. Fig. 7 shows a side cross-sectional view of the connector 1. The connector 1 includes an insulating housing 10, conductive terminals 30, a first cover 50, a second cover 70, and a sealing material 90 as a covering material. In the present embodiment, as an example, the connector includes three terminals 30, three first cover bodies 50, and three second cover bodies 70, but the number of each is not limited to three.

[0012] The housing 10 is, for example, a resin molded body, and accommodates and holds three terminals 30. The housing 10 has three first openings 11 that are opened to insert each terminal 30 into the housing 10, and three second openings 12 that are opened to expose each terminal 30 to the outside of the housing 10. The numbers of the first openings 11 and second openings 12 are not limited to three, and are set appropriately according to the number of terminals 30.

[0013] As shown in Fig. 2 etc., the three first openings 11 are provided side by side in the left-right direction on the bottom surface of the housing 10. As shown in Fig. 1 etc., the three second openings 12 are provided side by side in the left-right direction across the front and top surfaces of the housing 10.

[0014] 8, 10, 13 and 15, the housing 10 has grooves 17, 18 that hold the held portions 32 of the terminals 30. The grooves 17, 18 are provided above the rear of each of the first openings 11 and extend in the vertical direction.

[0015] The grooves 17 and 18 are located on the inner side of the housing 10 relative to the first lid body 50 and the second lid body 70. The first lid body 50 and the second lid body 70 will be described in detail later. The lower ends of the grooves 17 and 18, i.e., the ends on the first lid body 50 and the second lid body 70 side, are inlets for inserting the held portion 32 from below and open downward. The right part of the held portion 32 is inserted and held in the groove 17. The left part of the held portion 32 is inserted and held in the groove 18. The inlets of the grooves 17 and 18 are blocked by the held portion 32 and the first lid body 50 and the second lid body 70 to an extent that the uncured sealing material 90 cannot penetrate.

[0016] 2 and other drawings, the housing 10 has a surrounding portion 14. The surrounding portion 14 is a convex portion located on the outer periphery of the lower end of the housing 10 and extending in a substantially rectangular shape, and protrudes downward so as to surround the front, rear, left and right of the lower ends of the three first openings 11.

[0017] As shown in Fig. 2 etc., the housing 10 has holding portions 15, 16 on both left and right side surfaces for holding the mounting portions 81, 82. The mounting portions 81, 82 are sheet metal parts formed, for example, by pressing a metal plate. The mounting portions 81, 82 are connected, by soldering or the like, to a board 95 (Fig. 7) on which the connector 1 is to be mounted, and the housing 10 is fixed to the board 95.

[0018] The terminal 30 is a sheet metal part made of a metal material such as beryllium copper or titanium copper, and formed by pressing a metal plate. The terminal 30 may be formed by molding or cutting. The terminal 30 may also be subjected to a surface plating treatment. In this embodiment, as shown in Figs. 7 and 9 to 12, the terminal 30 has a leg portion 31, a held portion 32, a surface mounting portion 35, a leaf spring portion 37, and a contact portion 38.

[0019] The leg 31 is a flat plate-like portion that is substantially perpendicular to the front-rear direction and extends parallel to the up-down direction. The leg 31 passes between the first cover 50 and the second cover 70, penetrates the sealing material 90, and extends downward from the first opening 11 toward the outside of the housing 10.

[0020] The surface mounting portion 35 is a portion bent for surface mounting below the sealing material 90, i.e., on the outer side of the housing 10. In this embodiment, the surface mounting portion 35 is a flat plate-shaped portion that is approximately perpendicular to the up-down direction, and bends from the lower end of the leg 31 and extends forward. As another example, the surface mounting portion 35 may be bent from the lower end of the leg 31 and extend backward, extend in the left-right direction, or be bifurcated. The surface mounting portion 35 is electrically connected by soldering or the like to a conductive pattern (not shown) on a substrate 95 (FIG. 7) on which the connector 1 is to be mounted, and the connector 1 is surface mounted.

[0021] 8, the held portion 32 is a flat plate-like portion that is approximately perpendicular to the front-rear direction and is connected to the upper portion of the leg portion 31. The held portion 32 is fitted (e.g., press-fitted) into the groove portions 17, 18 of the housing 10 and held in the groove portions 17, 18. The held portion 32 is sandwiched between the first cover body 50 and the second cover body 70 and has a shape that extends into the groove portions 17, 18.

[0022] The structure of the held portion 32 in the grooves 17, 18 in this embodiment will be described. The held portion 32 has a protrusion 33 on each of the left and right ends. The protrusion 33 is a protruding portion that bites into the left and right inner surfaces of the grooves 17, 18 and generates a holding force in the left and right direction. However, the holding structure is not limited to this form. Regarding the holding of the terminals 30 in the housing 10, a holding method using adhesion may be used instead of or in addition to the holding force provided by the protrusion 33.

[0023] 8 to 10, 13 and 15, the protrusion 33 passes through the entrances of the grooves 17, 18 downward and extends to between the first lid body 50 and the second lid body 70. The protrusion 33 may protrude downward from the first lid body 50 and the second lid body 70.

[0024] The leaf spring portion 37 has a generally inverted U-shape when viewed from the side, and is connected to the upper part of the held portion 32. The leaf spring portion 37 acts to provide the contact portion 38 with appropriate flexibility. The contact portion 38 is supported by the leaf spring portion 37, and faces the outside of the housing 10 from the second opening 12. The contact portion 38 is divided into two parts, left and right, and a terminal (e.g., a plug) of a mating connector (not shown) is inserted between them to provide an electrical connection.

[0025] 7, 9, and 12, the first lid body 50 and the second lid body 70 close the first opening 11. Furthermore, the held portion 32 and the protrusion 33 of the terminal 30 are located between the first lid body 50 and the second lid body 70. The first lid body 50 and the second lid body 70 are made of an elastic body such as silicone rubber, and their side peripheral portions (e.g., side peripheral surfaces) are pressed against the inner peripheral portion (e.g., inner peripheral surface) of the first opening 11 by their own elastic force, fitting into the first opening 11, and are held in the housing 10 in a state where the first opening 11 is closed.

[0026] The first lid body 50 covers a portion of the first opening 11 in front of the held portion 32 of the terminal 30. The back surface of the first lid body 50 elastically contacts the front surface of the held portion 32. The second lid body 70 covers a portion of the first opening 11 in rear of the held portion 32. The front surface of the second lid body 70 elastically contacts the back surface of the held portion 32. In other words, the first lid body 50 and the second lid body 70 cover the first opening 11 and sandwich the held portion 32 from the front-rear direction.

[0027] As shown in Figs. 7, 11 and 12, the first cover 50 has a first portion 51 and a second portion 52. The first portion 51 is a lower portion of the first cover 50 and fits into the first opening 11. The second portion 52 is an upper portion of the first cover 50 and protrudes upward from the upper surface of the first portion 51. The second portion 52 has a smaller dimension in the front-rear direction than the first portion 51. The second portion 52 protrudes from the first opening 11 into the space within the housing 10.

[0028] The first cover 50 has an inclined portion 63 on the side periphery of the first portion 51 excluding the back portion. The inclined portion 63 is an inclined surface that widens from above to below. The first cover 50 has an enclosing portion 64. The enclosing portion 64 is a convex portion that is located on the outer periphery of the underside of the first cover 50 and extends in a substantially rectangular shape. The first cover 50 has a recess 53 (or a hollowed-out portion) on the underside, i.e., the surface facing the outside of the housing 10. The recess 53 is surrounded by the enclosing portion 64 on the front, back, left and right sides.

[0029] When the side periphery of surrounding portion 64, excluding the back portion, fits into first opening 11, it is pressed against the inner periphery of first opening 11 and elastically deforms, generating a holding force for first opening 11. When the holding force is generated, due to the presence of recess 53, surrounding portion 64 can elastically deform and escape into recess 53, suppressing bending of first lid 50 in the vertical direction.

[0030] The first cover 50 has a recess 54 on its upper surface, i.e., the surface facing the inside of the housing 10. The first cover 50 has protrusions 55, 56 on the front and rear edges of the recess 54. The recess 54 prevents the first cover 50 from interfering with the terminals 30 or hindering the elastic deformation of the terminals 30 when the first cover 50 is bent upward. The protrusions 55, 56 prevent the terminals 30 from being excessively deformed.

[0031] As shown in Figs. 11 and 12, the second cover 70 has an inclined portion 73 on its side periphery excluding its front portion. The inclined portion 73 is an inclined surface that widens from above to below. The second cover 70 has an enclosing portion 74. The enclosing portion 74 is a convex portion that is located on the outer periphery of the underside of the second cover 70 and extends in a substantially rectangular shape. The second cover 70 has a recess 75 (or a hollowed-out portion) on its underside, i.e., the surface facing the outside of the housing 10. The recess 75 is surrounded by the enclosing portion 74 on the front, back, left and right sides.

[0032] When the side periphery of surrounding portion 74, excluding the front portion, fits into first opening 11, it is pressed against the inner periphery of first opening 11 and elastically deforms, generating a holding force for first opening 11. At this time, due to the presence of recess 75, surrounding portion 74 can elastically deform and escape into recess 75, suppressing bending of second cover 70 in the vertical direction.

[0033] The sealing material 90 is a urethane resin, an epoxy resin, or the like, and covers the first opening 11 blocked by the first lid 50 and the second lid 70 from the outer side of the housing 10. The sealing material 90 may be filled beyond the first opening 11 to a depth that touches the inner periphery of the surrounding portion 14.

[0034] The connector 1 is manufactured, for example, as follows.

[0035] As shown in FIG. 10 and other figures, the terminal 30 is inserted into the housing 10 through the first opening 11 of the housing 10, and the contact portion 38 of the terminal 30 faces the outside of the housing 10 through the second opening 12, and the leg portion 31 of the terminal 30 protrudes from the first opening 11. Next, the first cover 50 and the second cover 70 are assembled so as to close the first opening 11 and to sandwich the held portion 32 of the terminal 30. Next, a potting process is performed. Specifically, the uncured sealant 90 is filled so as to cover the first opening 11 closed by the first cover 50 and the second cover 70 from the outer side of the housing 10 (the lower side in the figure). Then, a curing process is performed on the sealant 90. The curing process method includes heat curing, curing by mixing two liquids, and the like.

[0036] This embodiment provides the following advantages.

[0037] (1) Since the first opening 11 of the housing 10 is closed with the first cover 50 and the second cover 70 and further covered with the sealing material 90, water that has entered the housing 10 from the second opening 12 can be prevented from leaking out from the first opening 11. This improves the waterproofing of the connector 1. In addition, waterproofing can be ensured while ensuring the range of motion of the mating connector.

[0038] (2) The leg 31 of the terminal 30 passes between the first cover 50 and the second cover 70, penetrates the sealing material 90, and extends downward from the first opening 11 toward the outside of the housing 10. Therefore, even if there is a surface mount portion 35 intended for surface mounting on a board, there is no problem in assembly, and it can easily accommodate surface mounting on various boards. If the first opening 11 is covered with a single cover, the leg 31 of the terminal 30 needs to penetrate the cover, and if there is a surface mount portion 35, it is difficult to penetrate the cover, which deteriorates assembly. This embodiment can suitably solve such problems.

[0039] (3) The back surface of the first lid body 50 elastically contacts the front surface of the held portion 32. Therefore, during the potting process, it is possible to prevent the uncured sealing material 90 from penetrating into the housing 10 from between the back surface of the first lid body 50 and the front surface of the held portion 32. Similarly, the front surface of the second lid body 70 elastically contacts the back surface of the held portion 32. Therefore, during the potting process, it is possible to prevent the uncured sealing material 90 from penetrating into the housing 10 from between the front surface of the second lid body 70 and the back surface of the held portion 32.

[0040] (4) The protrusion 33 of the held portion 32 of the terminal 30 passes through the entrances of the grooves 17 and 18 downward and extends to between the first cover 50 and the second cover 70. Therefore, even if the uncured sealant 90 penetrates between the first cover 50 and the second cover 70 during the potting process, it cannot pass through the protrusion 33 and the press-fitted portions of the grooves 17 and 18. Therefore, the uncured sealant 90 that penetrates between the first cover 50 and the second cover 70 can be prevented from penetrating into the housing 10. For comparison, a case will be considered in which the protrusion 133 exists only above the entrances of the grooves 17 and 18, as in the terminal 130 of the comparative example shown in Figs. 14 and 16. In this case, as shown in Fig. 14, the uncured sealant 90 is likely to penetrate into the housing 10 through a gap between the right surface of the held portion 132 below the protrusion 133 and the inner surface of the groove 17 facing it. Similarly, uncured sealing material 90 is likely to seep into housing 10 through a gap between the left surface of held portion 132 below protrusion 133 and the opposing inner surface of groove portion 18. According to the present embodiment, such infiltration of uncured sealing material 90 can be suitably suppressed.

[0041] (5) The first lid 50 and the second lid 70 are elastic bodies, and are fitted into the first opening 11 by their own elasticity and are held in the first opening 11. Therefore, a configuration for pressing the first lid 50 and the second lid 70 from below is not necessary, and it is easy to configure the legs 31 of the terminals 30 to protrude below the first lid 50 and the second lid 70 while suppressing an increase in the number of parts and costs. If the first lid 50 and the second lid 70 are not elastic bodies, it is necessary to assemble sheet metal parts or the like to the housing from below the lids to press the first lid 50 and the second lid 70. In the case of a configuration in which sheet metal parts are assembled to the housing 10, it is difficult to configure the legs 31 of the terminals 30 to protrude below the first lid 50 and the second lid 70 due to the presence of the sheet metal parts. In the present embodiment, such a disadvantage can also be eliminated.

[0042] (6) Since the first lid 50 and the second lid 70 are elastic, gaps are unlikely to form between the side peripheries of the first lid 50 and the second lid 70 and the inner periphery of the first opening 11, making it easy to control the filling range of the sealant 90. In other words, it is possible to prevent uncured sealant 90 from leaking and adhering to the inside of the housing 10 during the potting process.

[0043] (7) Since the recess 53 is provided on the underside of the first lid 50, when the side periphery of the surrounding portion 64 is pressed against the inner periphery of the first opening 11 and elastically deforms, the surrounding portion 64 can escape into the recess 53. This suppresses the first lid 50 from bending in the vertical direction. This suppresses the first lid 50 from bending downward and narrowing the filling range of the sealing material 90. It also suppresses the first lid 50 from bending upward and interfering with the terminal 30 or impeding the elastic deformation of the terminal 30.

[0044] (8) Since the recess 75 is provided on the underside of the second lid 70, when the side periphery of the surrounding portion 74 is pressed against the inner periphery of the first opening 11 and elastically deforms, the surrounding portion 74 can escape into the recess 75. This prevents the second lid 70 from bending downward and thus prevents the filling area of ​​the sealing material 90 from becoming narrower.

[0045] (9) The recess 54 is provided on the top surface of the first lid 50, so that when the first lid 50 is bent upward, it is possible to prevent the first lid 50 from interfering with the terminal 30 or hindering the elastic deformation of the terminal 30. Meanwhile, the first lid 50 has protrusions 55, 56 in front of and behind the recess 54, which define the amount of deformation of the terminal 30, so that excessive deformation of the terminal 30 can be prevented.

[0046] Although the embodiment and the modified examples of the present invention have been described above with reference to the drawings, these are merely examples of the present invention, and various configurations other than those described above may be adopted. For example, the number of the first openings 11 and the second openings 12 and the number of the terminals 30 of the housing 10 are not limited to three, and may be any number. For example, an example in which there are two lids, the first lid 50 and the second lid 70, has been shown, but the number of lids is not limited to two, and may be any number.

[0047] The shapes of the first opening 11 and the first and second lids 50 and 70 covering the first opening 11 can be appropriately changed to match the shapes of the terminals 30. In addition, the shape of the second opening 12 can be appropriately changed to match the shapes of the terminals 30 and the terminals of the mating connector.

[0048] The configuration of the first lid body 50 and the second lid body 70 is not limited to the present embodiment. For example, the first lid body 50 and the second lid body 70 may have no second portion 52, no protruding portions 55 and 56, or no recessed portions 53 and 75 (recessed portions).

[0049] According to the present specification, there is provided a connector having the following aspects.

[0050] (Aspect 1) a housing having an opening; A terminal accommodated in the housing; A plurality of lids for closing the openings; a covering material that covers the openings that are closed by the plurality of lids from an outer side of the housing, The terminals pass between the multiple lids, penetrate the covering material, and extend outwardly of the housing.

[0051] According to the first aspect, the opening of the housing is closed with a plurality of lids and further covered with a covering material, thereby improving waterproofing.

[0052] (Aspect 2) The terminals are bent for surface mounting on an outer side of the housing relative to the covering material.

[0053] According to aspect 2, it is easy to accommodate surface mounting. Since the terminals pass between a plurality of lids, even if there are portions bent for surface mounting, the difficulty in assembly is reduced.

[0054] (Aspect 3) The terminal has a held portion, The housing has a groove into which the held portion fits, the held portion is sandwiched between the plurality of lid bodies and extends into the groove portion, A connector in which the held portion and the multiple lids block the entrance of the groove to an extent that uncured coating material cannot enter through the entrance of the groove.

[0055] According to the third aspect, it is possible to prevent the uncured coating material from penetrating into the housing.

[0056] (Aspect 4) A connector, wherein the held portion has a protrusion that generates a holding force against the inner surface of the groove portion, and the protrusion is covered by the multiple lids.

[0057] According to the fourth aspect, it is possible to suppress the uncured coating material from penetrating into the housing, as compared with a case in which the protrusions are not covered by the plurality of lids.

[0058] (Aspect 5) The multiple lid bodies are elastic bodies, and their elastic force causes their side peripheral portions to be pressed against the inner peripheral portion of the opening and to clamp the held portion.

[0059] According to the fifth aspect, a configuration for holding down a plurality of lids is not required, and an increase in the number of parts and costs can be suppressed. Also, it is possible to suppress the infiltration of uncured coating material into the housing through gaps between each of the first and second lids and the held portion.

[0060] (Aspect 6) the housing has a second opening; The terminal faces outside the housing through a second opening.

[0061] According to the sixth aspect, since the opening of the housing is closed with the plurality of lids and further covered with the covering material, it is possible to prevent water that has entered the housing from the second opening from leaking out of the opening. This makes it possible to improve the waterproofing. In addition, it is possible to ensure the waterproofing while ensuring the movable range of the mating connector.

[0062] (Aspect 7) a housing having an opening, a terminal is inserted into the housing through the opening, and the terminal is placed in a state where it protrudes from the opening; a plurality of elastic bodies are assembled to the opening so as to close the opening and to sandwich a portion of the terminal; A method for manufacturing a connector, comprising the steps of: filling a coating material so as to cover the openings blocked by the plurality of elastic bodies from the outer side of the housing.

[0063] According to the seventh aspect, the opening of the housing is closed with multiple lids and further covered with a covering material, which improves waterproofing. Also, unlike the case where the opening is closed with a single elastic body, there is no need to penetrate the elastic body into the terminal, so it can accommodate terminals of various shapes and is easy to assemble.
