Description

[Technical Field]

[0001] The present disclosure relates to connectors. [Background technology]

[0002] The connector disclosed in Patent Document 1 includes terminals and a housing that holds the terminals. The terminals are attached to the housing by passing through its main body. The terminals have a first contact portion that protrudes upward from the main body, a second contact portion that protrudes downward from the main body, and a folded portion that is embedded in the main body by insert molding.

[0003] The folded portion has a first location extending downward from the first contact point, a second location bending from the bottom end of the first location to extend leftward, and a third location bending from the left end of the second location to extend upward. The folded portion also has a fourth location bending from the top end of the third location to extend leftward, and a fifth location bending from the left end of the fourth location to extend downward. The second contact point extends downward from the fifth location. The above-mentioned references to the up, down, left, and right directions are based on the up, down, left, and right directions in Figure 5 of Patent Document 1, and differ from the references to directions described in the specification of Patent Document 1.

[0010] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The connector of the present disclosure comprises: (1) A housing having a holding portion and a terminal held by the holding portion, wherein the terminal has a first connection portion that protrudes downward from the holding portion, a second connection portion that protrudes upward from the holding portion, and an attachment portion that is located between the first connection portion and the second connection portion and is positioned inside the holding portion, and the attachment portion has an extension portion that extends upward from the side of the first connection portion and an inclined portion that extends diagonally downward from the extension portion at an acute angle to the vertical direction.

[0011] For example, when the first connection part is disposed on the oil layer side and the second connection part is disposed on the gas layer side, the inclined part extending diagonally downward from the extension part can effectively prevent oil on the oil layer side from migrating to the gas layer side. In particular, since the inclined part can prevent liquid from penetrating into the second connection part side, it is possible to omit a potting material or the like that liquid-tightly seals the area around the base of the second connection part from the connector.

[0012] (2) In the connector described in (1) above, it is preferable that the mounting portion has an intermediate portion extending upward from the inclined portion and an opposing inclined portion extending diagonally downward from the intermediate portion at an acute angle with respect to the vertical direction, and that the opposing inclined portion is positioned opposite the inclined portion from above.

[0013] Since the mounting portion has an inclined portion and an opposing inclined portion that extends diagonally downward from the middle portion, it is possible to more reliably prevent fluids such as oil from moving from the first connection portion to the second connection portion. Also, since the opposing inclined portion is positioned opposite the inclined portion from above, it is possible to avoid the terminal from becoming larger as a whole.

[0014] (3) In the connector described in (1) or (2) above, it is preferable that the extension portion is a portion that extends in the vertical direction in the mounting portion, and the inclined portion is a portion that bends from the upper end of the extension portion and extends diagonally downward in the mounting portion.

[0015] Since the mounting portion as a whole has a shape that is bent from the extending portion to the inclined portion, it is possible to more reliably prevent liquid such as oil from moving from the first connecting portion side to the second connecting portion side.

[0016] (4) In the connector described in (2) above, it is preferable that the extension portion is a portion that extends in the vertical direction in the mounting portion, the inclined portion is a portion that bends from the upper end of the extension portion in the mounting portion and extends diagonally downward, the intermediate portion is a portion that bends from the lower end of the inclined portion in the mounting portion and extends upward, and the opposing inclined portion is a portion that bends from the upper end of the intermediate portion in the mounting portion and extends diagonally downward.

[0017] Since the mounting portion as a whole is shaped to bend from the extension portion to the inclined portion, and then further bend from the middle portion to the opposing inclined portion, it is possible to more reliably prevent liquids such as oil from moving from the first connection portion side to the second connection portion side.

[0018] (5) In the connector described in (4) above, the holding portion has a terminal holder and a covering portion that covers part or all of the terminal holder holding the terminal, and the terminal holder has a mounting groove that opens over three sides of the outer surface of the terminal holder, and it is preferable that the inclined portion, the intermediate portion and the opposing inclined portion are arranged so as to be able to contact each of the groove surfaces on the three sides of the mounting groove.

[0019] The inclined portion, the intermediate portion, and the opposing inclined portion are arranged so as to be in contact with each of the three groove surfaces of the mounting groove, thereby enabling the terminal to be held in a positioned state in the terminal holder. In particular, the inclination angle between the extension portion and the inclined portion and the inclination angle between the intermediate portion and the opposing inclined portion can be accurately determined by each surface of the mounting groove. Furthermore, for example, when the cover portion is shaped to cover the terminal holder by insert molding, the terminal is held in a positioned state in the terminal holder, preventing deformation of the terminal due to molding pressure, etc.

[0020] (6) In the connector described in (2) above, it is preferable that the mounting portion has a recess that is recessed in a direction that reduces the thickness of the mounting portion, the intermediate portion is an intermediate surface extending in the vertical direction on the inner surface at the back of the recess, the inclined portion is an inclined surface extending diagonally downward toward the intermediate surface on the inner surface at the lower side of the recess, and the opposing inclined portion is an opposing inclined surface extending diagonally downward toward the intermediate surface on the inner surface at the upper side of the recess.

[0021] According to the above configuration (6), the extending portion (extending surface), the inclined portion (inclined surface), the intermediate portion (intermediate surface), and the opposing inclined portion (opposing inclined surface) can be formed within the thickness range of the mounting portion.

[0022] [Details of the embodiments of the present disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. However, the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0023] <Embodiment 1> As shown in FIG. 1, the connector 10 of the first embodiment includes a plurality of terminals 60, a housing 20 that holds the terminals 60, and a seal ring 100 attached to the housing 20. A collar 140 is attached to the housing 20. The connector 10 is fixed to a lid 111 (see FIG. 3) of a case 110, such as an oil case for an automatic transmission, via a bolt (not shown) that passes through the collar 140. In the following description, the vertical direction refers to the axial direction of the connector 10 fixed to the lid 111 of the case 110. The housing 20 is mated with a mating connector (not shown) from above. The left side of FIG. 2 (the direction in which the collar 140 is located) is defined as the front. The left-right direction is defined as the left-right direction when viewed from the front. In each drawing, the symbols X, Y, and Z represent the front, left, and top.

[0024] (Housing 20) 1 to 3, the housing 20 is made of synthetic resin and has a first hood section 21 that opens downward, a second hood section 22 that opens upward, and a retaining section 23 that separates the first hood section 21 and the second hood section 22. The first hood section 21 and the second hood section 22 are shaped like a flat cylinder that is elongated in the front-to-rear direction.

[0025] As shown in Fig. 3, the first hood section 21 is disposed inside the case 110 (below the lid section 111). A mating connector on the oil layer side (not shown) is fitted into the inside of the first hood section 21 from below. The second hood section 22 is disposed outside the case 110 (above the lid section 111). A mating connector on the air layer side (not shown) is fitted into the inside of the second hood section 22 from above.

[0026] 1 and 2, the holding portion 23 has a curved outer peripheral shape as a whole. A fitting groove 24 is formed around the entire circumference of the outer peripheral surface of the holding portion 23 on the side of the first hood portion 21. A seal ring 100 is attached to the fitting groove 24 of the holding portion 23. The seal ring 100 is made of rubber such as silicone rubber, and as shown in FIG. 3, fits tightly to the inner peripheral surface of the mounting hole 112 of the lid portion 111, maintaining a liquid-tight seal between the connector 10 and the case 110.

[0027] As shown in Fig. 2, an attachment piece 25 is formed on the holding portion 23 so as to protrude forward. The attachment piece 25 is a plate-like piece having a thickness in the vertical direction, and is arranged along the front-to-rear direction. The attachment piece 25 is placed on the upper surface of the lid portion 111. An insertion hole 26 is formed in the attachment piece 25 so as to pass through in the vertical direction. A collar 140 is fitted into the insertion hole 26 of the attachment piece 25.

[0028] 3, the holding portion 23 is composed of a terminal holder 27 disposed inside and a cover portion 28 disposed outside. The cover portion 28 is composed of the portion of the housing 20 other than the terminal holder 27. Therefore, the first hood portion 21 and the second hood portion 22 are included in the cover portion 28. The terminal holder 27 holds a plurality of terminals 60.

[0029] As shown in FIGS. 6 and 7 , a terminal unit 29 is formed by terminal holders 27 holding terminals 60. The terminal holder 27 includes a holder body 31 shaped like a rectangular block elongated in the front-rear direction and protrusions 32 protruding from the front and rear end faces of the holder body 31. A plurality of mounting grooves 33 are formed on each of the left and right side faces of the holder body 31 and aligned in the front-rear direction. In the first embodiment, each mounting groove 33 opens from the right side (one side) of the holder body 31 to the top and bottom faces, and further opens from the top face to the upper end of the left side face and from the bottom face to the lower end of the left side face. The opening width of the mounting groove 33 in the front-rear direction corresponds to the front-rear thickness of the terminal 60. In short, the mounting groove 33 has a narrow slit-like opening width. A corresponding terminal 60 is fitted into each mounting groove 33 from the right side (one side).

[0030] 4, in a cross section obtained by cutting the holder body 31 in the vertical direction, the rear surface of the mounting groove 33 in the depth direction has a pair of opposing side portions 34 that extend in the left-right direction while facing parallel to each other in the vertical direction, an inclined side portion 35 and an opposing inclined side portion 36 that expand rightward from the right end (one side end) of each opposing side portion 34, and an extended side portion 37 that extends in the vertical direction and connects to the right ends of the inclined side portion 35 and the opposing inclined side portion 36. The opposing inclined side portion 36 is disposed above the inclined side portion 35 and opposite the inclined side portion 35. A mounting portion 62 of the terminal 60, which will be described later, is disposed along the rear surface of the mounting groove 33 of the terminal holder 27.

[0031] (Terminal 60) The terminal 60 is made of a conductive metal and has a pin shape, more specifically a square pin shape, and has an elongated shape overall. As shown in Fig. 5, the terminal 60 has a first connecting portion 61, an attachment portion 62, and a second connecting portion 63. The first connecting portion 61 is shaped to extend in the vertical direction at the bottom of the terminal 60. The second connecting portion 63 is shaped to extend in the vertical direction at the top of the terminal 60. The first connecting portion 61 and the second connecting portion 63 are arranged coaxially in the vertical direction via the attachment portion 62.

[0032] 3, the first connection portion 61 protrudes downward from the holding portion 23 and is disposed inside the first hood portion 21. The first connection portion 61 is electrically connected to a mating terminal (not shown) attached to the connector 10 on the oil layer side. The second connection portion 63 protrudes upward from the holding portion 23 and is disposed outside the second hood portion 22. The second connection portion 63 is electrically connected to a mating terminal (not shown) attached to the connector 10 on the gas layer side.

[0033] The mounting portion 62 is mounted in the mounting groove 33 of the terminal holder 27 and is entirely embedded inside the holding portion 23. Specifically, as shown in Fig. 4, the mounting portion 62 has a first extending portion 64 (corresponding to the "extending portion" in this disclosure) extending upward and continuous with the first connecting portion 61, and an inclined portion 65 extending obliquely downward from the upper end of the first extending portion 64 toward the right side (one side). Furthermore, the mounting portion 62 has a second extending portion 66 extending downward and continuous with the second connecting portion 63 at a position above the first extending portion 64, an opposing inclined portion 67 extending obliquely upward from the lower end of the second extending portion 66 toward the right side, and an intermediate portion 68 extending in the vertical direction, the upper end of which is continuous with the right end (one side end) of the opposing inclined portion 67 and the lower end of which is continuous with the right end (one side end) of the inclined portion 65. The first extending portion 64 and the second extending portion 66 are arranged coaxially in the vertical direction. The inclined portion 65 and the opposing inclined portion 67 oppose each other in the vertical direction and widen toward the right.

[0034] The inclined portion 65 is inclined linearly obliquely downward from the upper end of the first extending portion 64 at an acute angle (less than 90 degrees) with respect to the vertical direction (extension direction of the first extending portion 64). The opposing inclined portion 67 is inclined linearly obliquely downward from the upper end of the intermediate portion 68 at an acute angle with respect to the vertical direction (extension direction of the intermediate portion 68). Furthermore, the inclined portion 65 is inclined linearly obliquely upward from the lower end of the intermediate portion 68 at an acute angle with respect to the vertical direction. The opposing inclined portion 67 is inclined linearly obliquely upward from the lower end of the second extending portion 66 at an acute angle with respect to the vertical direction.

[0035] As shown in Fig. 5, recesses 71 are formed on the front and rear surfaces of the intermediate portion 68. Each recess 71 is formed within the thickness range of the intermediate portion 68 in the front-to-rear direction. Each recess 71 is symmetrical with respect to the front-to-rear center of the intermediate portion 68. In the case of the first embodiment, each recess 71 is formed by press-punching the intermediate portion 68.

[0036] As shown in FIG. 8 , the front and rear surfaces of the intermediate portion 68 have a first extending surface 72 extending in the vertical direction at the lower portion of the upper and lower portions of the recess 71, and a second extending surface 73 extending in the vertical direction at the upper portion. The inner surface of each recess 71 has a middle surface 74 extending in the vertical direction at the back side in the depth direction of the recess 71. The middle surface 74 is disposed vertically in the vertical direction. The inner surface of the lower side of each recess 71 forms an inclined surface 75 that extends obliquely downward at an acute angle from the upper end of the front and rear first extending surface 72 with respect to the vertical direction. The deepest end of the inclined surface 75 is connected to the lower end of the middle surface 74. The inner surface of the upper side of each recess 71 forms an opposing inclined surface 76 that extends obliquely downward at an acute angle from the upper end of the middle surface 74 with respect to the vertical direction. The open end of the opposing inclined surface 76 is connected to the lower end of the second extending surface 73. The inclined surface 75 and the opposing inclined surface 76 face each other in the vertical direction and widen toward the intermediate surface 74 .

[0037] (action) As shown in FIGS. 6 and 7 , each terminal 60 is mounted on the terminal holder 27 from a position on the right side of the terminal holder 27. The mounting portion 62 of each terminal 60 is fitted into the corresponding mounting groove 33 of the terminal holder 27. Specifically, as shown in FIG. 4 , the intermediate portion 68 is disposed along the extending side portion 37 of the mounting groove 33, the inclined portion 65 is disposed along the inclined side portion 35 of the mounting groove 33, and the opposing inclined portion 67 is disposed along the opposing inclined side portion 36 of the mounting groove 33. Here, the mounting portion 62 can elastically contact the inner surface of the mounting groove 33 of the terminal holder 27. As a result, the inclination angle between the intermediate portion 68 and the inclined portion 65 and the inclination angle between the intermediate portion 68 and the inclined portion 67 are constant. The terminal 60 is positioned and held in the terminal holder 27.

[0038] As described above, the terminal holders 27 holding the terminals 60 constitute a terminal unit 29. As shown in Fig. 7, in the terminal unit 29, the first connection portions 61 of each terminal 60 are arranged so as to protrude downward from the mounting grooves 33 of the terminal holder 27, and the second connection portions 63 of each terminal 60 are arranged so as to protrude upward from the mounting grooves 33 of the terminal holder 27.

[0039] Next, the terminal unit 29 is placed in an injection molding mold (not shown). The terminal unit 29 is positioned and supported in the mold by the protrusions 32 of the terminal holder 27. During injection molding, resin is injected into the mold. This covers the periphery of the terminal unit 29 with resin, and a cover portion 28 having a holding portion 23, a first hood portion 21, and a second hood portion 22 is molded. The connector 10 is then formed, consisting of the terminal unit 29 and the cover portion 28. In the connector 10, the mounting portion 62 is embedded inside the holding portion 23.

[0040] When the connector 10 is mounted on a vehicle or the like (not shown), the first hood portion 21 is placed in an oil environment inside the case 110, and the second hood portion 22 is placed above the lid portion 111 in an air environment outside the case 110. Oil inside the case 110 may enter the inside of the first hood portion 21, adhere to the first connecting portion 61, rise from the first connecting portion 61 along the first extending portion 64, and then move between the inclined portion 65 and the inclined side portion 35 toward the intermediate portion 68. Here, the inclined portion 65 is shaped to extend obliquely downward, bending at an acute angle with respect to the extending direction of the first extending portion 64. In other words, the inclined portion 65 is shaped to detour in a direction returning to the first connecting portion 61 side, opposite the second connecting portion 63 side (see FIG. 4). For this reason, pressure loss occurs as the oil moves along the inclined portion 65, and even when it reaches the intermediate portion 68, the momentum of the oil rising up the intermediate portion 68 is weakened.

[0041] Even if oil attempts to rise up the intermediate portion 68, when passing between the groove surface of the mounting groove 33 of the terminal holder 27 and each recess 71 (see FIG. 8), it will be detouring along the inclined surface 75, the intermediate surface 74, and the opposing inclined surface 76, causing a pressure loss as described above. Therefore, the oil is effectively prevented from moving toward the upper end side of the intermediate portion 68.

[0042] Even if the oil does reach the upper end of the intermediate section 68, as the oil moves from the upper end of the intermediate section 68 along the opposing inclined section 67, a pressure loss occurs due to the bypass path, as described above, and therefore the movement of oil toward the second extension section 66 is suppressed with high certainty.

[0043] As a result, oil on the oil layer side is prevented from migrating toward the second connecting portion 63 side, and it is possible to ensure sealing inside the second hood portion 22. As a result, it is possible to omit the potting material that has conventionally been filled inside the second hood portion 22 to seal around the base of the second connecting portion 63.

[0044] As described above, the connector 10 of the first embodiment includes a housing 20 having a retaining portion 23, and a terminal 60 attached to the retaining portion 23. The terminal 60 has a first connecting portion 61 arranged to protrude downward from the retaining portion 23, a second connecting portion 63 arranged to protrude upward from the retaining portion 23, and an attaching portion 62 positioned between the first connecting portion 61 and the second connecting portion 63 and penetrating the retaining portion 23. The attaching portion 62 has a first extending portion 64 extending upward from the side of the first connecting portion 61, and an inclined portion 65 extending diagonally downward from the first extending portion 64 at an acute angle relative to the up-down direction.

[0045] For example, when the first connecting portion 61 is disposed on the oil layer side and the second connecting portion 63 is disposed on the gas layer side, the inclined portion 65 extending diagonally downward from the first extending portion 64 can prevent oil on the oil layer side from migrating to the gas layer side. In particular, since the inclined portion 65 does not have a crank-shaped bend, the terminal 60 does not need to have a complex folded shape. Furthermore, since the inclined portion 65 can prevent liquid from entering the second connecting portion 63 side, it is possible to omit the potting material that liquid-tightly seals the area around the base of the second connecting portion 63 from the connector 10.

[0046] Furthermore, in the case of the first embodiment, the mounting portion 62 has an intermediate portion 68 extending upward from the inclined portion 65, and an opposing inclined portion 67 extending diagonally downward from the intermediate portion 68 at an acute angle with respect to the up-down direction. The opposing inclined portion 67 is disposed facing the inclined portion 65 from above. In this way, if the mounting portion 62 has the opposing inclined portion 67 extending diagonally downward from the intermediate portion 68 in addition to the inclined portion 65, it is possible to more reliably prevent oil from migrating from the first connecting portion 61 side to the second connecting portion 63 side. Furthermore, because the opposing inclined portion 67 is disposed facing the inclined portion 65 from above, it is possible to avoid the terminal 60 from becoming larger as a whole.

[0047] In the first embodiment, the first extending portion 64 is a portion of the mounting portion 62 that extends in the vertical direction, and the inclined portion 65 is a portion of the mounting portion 62 that bends from the upper end of the first extending portion 64 and extends diagonally downward. In this way, the mounting portion 62 as a whole has a shape that bends from the first extending portion 64 to the inclined portion 65, which makes it possible to more reliably prevent oil from moving from the first connecting portion 61 side to the second connecting portion 63 side.

[0048] Furthermore, in the case of the first embodiment, the first extending portion 64 is a portion of the mounting portion 62 that extends in the up-down direction, and the inclined portion 65 is a portion of the mounting portion 62 that bends from the upper end of the first extending portion 64 and extends diagonally downward. The intermediate portion 68 is a portion of the mounting portion 62 that bends from the lower end of the inclined portion 65 and extends upward, and the opposing inclined portion 67 is a portion of the mounting portion 62 that bends from the upper end of the intermediate portion 68 and extends diagonally downward. In this way, the mounting portion 62 as a whole has a shape that bends from the first extending portion 64 to the inclined portion 65 and further bends from the intermediate portion 68 to the opposing inclined portion 67, which more reliably prevents oil from moving from the first connecting portion 61 side to the second connecting portion 63 side.

[0049] Furthermore, in the first embodiment, the holding portion 23 includes a terminal holder 27 and a cover portion 28 that covers the terminal holder 27 holding the terminals 60. The terminal holder 27 has a mounting groove 33 that opens across three outer surfaces of the terminal holder 27, and the inclined portion 65, the intermediate portion 68, and the opposing inclined portion 67 are arranged so as to be able to contact the respective groove surfaces on the three sides of the mounting groove 33. The inclined portion 65, the intermediate portion 68, and the opposing inclined portion 67 are arranged so as to be able to contact the respective groove surfaces on the three sides of the mounting groove 33, thereby allowing the terminals 60 to be held in a positioned state in the terminal holder 27. In particular, the inclination angle between the first extension portion 64 and the inclined portion 65 and the inclination angle between the intermediate portion 68 and the opposing inclined portion 67 can be accurately determined by the respective surfaces of the mounting groove 33. Furthermore, when the cover portion 28 is shaped to cover the terminal holder 27 by insert molding, the terminals 60 are held in a positioned state in the terminal holder 27, preventing the terminals 60 from being deformed by molding pressure or the like.

[0050] Furthermore, in the first embodiment, the mounting portion 62 has a recess 71 recessed in a direction that reduces the thickness of the mounting portion 62. The middle portion 68 is a middle surface 74 extending in the vertical direction on the inner surface at the back of the recess 71, the inclined portion 65 is a middle surface 75 extending obliquely downward toward the middle surface 74 on the inner surface at the lower side of the recess 71, and the opposing inclined portion 67 is an opposing inclined surface 76 extending obliquely downward toward the middle surface 74 on the inner surface at the upper side of the recess 71. Thus, the first extending portion 64 (first extending surface 72), the inclined portion 65 (inclined surface 75), the middle portion 68 (middle surface 74), and the opposing inclined portion 67 (opposing inclined surface 76) can be formed within the thickness range of the mounting portion 62. Note that, in the first embodiment, the crank shape of the mounting portion 62 is formed by bending. However, the crank shape of the mounting portion may also be formed by punching a metal plate.

[0051] [Another embodiment of the present disclosure] The first embodiment disclosed herein should be considered to be illustrative in all respects and not restrictive. In the first embodiment, the second hood portion protrudes upward from the holding portion and is open upward. In contrast, according to other embodiments, the second hood portion may protrude upward from the holding portion and be open in either the front-rear direction or the left-right direction. Similarly, the second connection portion protruding into the second hood portion may be bent above the holding portion and be shaped to protrude in either the front-rear direction or the left-right direction. In the first embodiment, the potting material was omitted from the connector. In contrast, in other embodiments, the second hood portion may be filled with a sealing material such as a potting material to further improve the sealing performance around the terminals. In other words, a sealing material such as a potting material may be applied as needed, and the present disclosure does not deny the use of a sealing material. In the first embodiment, the recesses are formed on both the front and rear surfaces of the intermediate portion. In contrast, in other embodiments, the recesses may be formed on only one of the front and rear surfaces of the intermediate portion. Alternatively, the recesses may be formed on at least one of the left and right surfaces of the intermediate portion. In the first embodiment, the recess is formed in the middle portion of the mounting portion. In contrast to this, in other embodiments, the recess may be formed in at least one of the inclined portion and the opposing inclined portion of the mounting portion. In the first embodiment, the terminal holder is entirely covered by the cover portion. In contrast to this, according to other embodiments, the terminal holder may have an exposed portion that is not covered by the cover portion. In the first embodiment, the first extending portion, the inclined portion, the intermediate portion, and the opposing inclined portion are formed by the bent shape of the terminal and by extending surfaces, inclined surfaces, intermediate surfaces, and opposing inclined surfaces recessed into the outer surface of the terminal. In contrast, in other embodiments, the extending portion, the inclined portion, the intermediate portion, and the opposing inclined portions may be formed by either the bent shape of the terminal or by extending surfaces, inclined surfaces, intermediate surfaces, and opposing inclined surfaces recessed into the outer surface of the terminal. In the first embodiment, the terminal is embedded in the holding portion while being held by the terminal holder. In contrast, in other embodiments, the terminal may be insert-molded into the holding portion without being held by the terminal holder. In the first embodiment, the terminal holder is molded and held in the cover by injection molding. In contrast, in other embodiments, the terminal holder may be held by being press-fitted into a pre-molded cover. In the first embodiment, the mounting groove is open from the right side surface of the terminal holder body to the top and bottom surfaces, and further from the top surface to the upper end of the left side surface, and from the bottom surface to the lower end of the left side surface. In contrast, in other embodiments, the mounting groove may be open from the right side surface of the terminal holder body to the top and bottom surfaces, and may be closed on the left side surface.
