Abstract
Description
[Technical Field]
[0001] The present invention relates to an electrical connector that is connected to a substrate. [Background technology]
[0002] Conventionally, as an electrical connector to be connected to a board, an electrical connector has been known that includes a housing that is placed on the board while passing through a through hole provided in the board, and contacts that are inserted into and held in the housing (see, for example, Patent Document 1). In this electrical connector, because the housing is placed on the board while passing through the through hole in the board, the overall thickness of the board and the electrical connector attached to the board can be made thin, and the overall structure of the board and electrical connector can be made low-profile.
[0003] In the electrical connector disclosed in Patent Document 1, the contact insertion direction in which the contacts are inserted into the housing is set to be perpendicular to the thickness direction of the housing and parallel to the surface of the board when the housing passes through the through-hole of the board. If the contact insertion direction is set to be parallel to the thickness direction of the housing, the position of each contact held in the housing is likely to vary relative to the thickness direction of the housing. If the position of each contact varies in the thickness direction of the housing, the contact position between each contact and the surface of the board will vary in the thickness direction of the housing. However, by setting the contact insertion direction to be perpendicular to the thickness direction of the housing and parallel to the surface of the board when the housing passes through the through-hole of the board, it is possible to prevent the contact position between each contact and the surface of the board in the thickness direction of the housing from varying. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Patent No. 6467224 specification Summary of the Invention [Problem to be solved by the invention]
[0005] When the insertion direction of the contact is perpendicular to the thickness direction of the housing and parallel to the surface of the board when the housing penetrates the through-hole of the board, a notch is provided on the edge of the housing perpendicular to the thickness direction of the housing at a portion that communicates with the groove into which the contact is inserted. That is, in this case, since the contact inserted into the housing in the direction perpendicular to the thickness direction of the housing is connected to the board, the edge of the housing needs an area through which the portion of the contact that connects the portion inserted into the housing and the portion connected to the board can pass when the contact is inserted into the housing, and a notch is provided on the edge of the housing by cutting out the edge of the housing. By providing a notch on the edge of the housing, a gap is formed on the edge of the housing that penetrates the housing in the thickness direction. Because the housing is disposed in the through-hole of the board, if there is a gap on the edge of the housing, light will leak from the gap formed in the housing that penetrates the through-hole of the board when a light source is located near the board. For example, when a board with an electrical connector attached is used in a backlight device provided in a liquid crystal display device, light from a light source such as an LED will leak to the outside through a gap at the edge of the housing that passes through the through hole in the board.
[0006] In view of the above-mentioned circumstances, the present invention aims to provide an electrical connector that can prevent light from leaking through gaps in the housing of the electrical connector that passes through a through hole in a board. [Means for solving the problem]
[0007] (1) An electrical connector according to one aspect of the present invention for achieving the above object is an electrical connector connected to a board, the electrical connector comprising: a housing that is positioned relative to the board while passing through a through hole provided in the board; and contacts that are inserted into the housing in a predetermined insertion direction and held by the housing, the insertion direction being perpendicular to the thickness direction of the housing and set in a direction parallel to the surface of the board when the housing passes through the through hole, the contacts having a board connection portion that is connected to the board, a housing insertion portion that is inserted into the housing, and a connecting portion that connects the board connection portion and the housing insertion portion, the contacts having a protrusion that extends from a board-side connecting portion that is a portion of the connecting portion that is continuous with the board connection portion in a direction perpendicular to the thickness direction of the housing and that protrudes in a width direction of the housing that is a direction perpendicular to the thickness direction of the housing and the insertion direction, the protrusion being arranged so that a tip side portion of the protrusion that protrudes in the width direction of the housing overlaps with the housing in the thickness direction of the housing.
[0008] According to this configuration, the housing of the electrical connector is placed on the board while passing through the through-hole of the board, so the overall thickness of the board and the electrical connector attached to the board can be made thin, and the overall structure of the board and electrical connector can be made low-profile. Furthermore, with this configuration, the insertion direction of the contacts into the housing is set to a direction perpendicular to the thickness direction of the housing and parallel to the surface of the board when the housing passes through the through-hole of the board. Therefore, it is possible to prevent variation in the contact position between each contact and the surface of the board in the thickness direction of the housing.
[0009] Furthermore, according to the above configuration, the contact has a protrusion extending from a board-side connecting portion, which is a portion of the connecting portion connecting the housing insertion portion and the board connecting portion that is continuous with the board connecting portion, in a direction perpendicular to the thickness direction of the housing and protruding in the width direction of the housing. The protrusion is positioned so that the tip end portion protruding in the width direction of the housing overlaps with the housing in the thickness direction of the housing. Therefore, even if a notch formed by cutting out an edge of the housing is provided in the edge of the housing and a gap penetrating the housing in the thickness direction is formed in the edge of the housing, the protrusion can cover and seal the gap in the thickness direction of the housing. This makes it possible to prevent light from leaking to the outside through the gap in the edge of the housing that penetrates the through-hole in the board, even when the light source is located near the board.
[0010] As described above, the above configuration makes it possible to provide an electrical connector that can prevent light from leaking through gaps in the housing of the electrical connector that passes through the through hole in the substrate.
[0011] (2) The protruding portion may be provided so as to extend in a plate shape from the board-side connecting portion along a direction perpendicular to the thickness direction of the housing.
[0012] With this configuration, the protrusion extends in a plate-like shape from the board-side connecting portion in a direction perpendicular to the thickness direction of the housing, thereby efficiently covering and sealing the gaps at the edge of the housing and more effectively preventing light leakage.
[0013] (3) The housing may be provided with a recessed portion that is arranged to fit into a tip end portion of the protruding portion that protrudes in the width direction of the housing.
[0014] With this configuration, the housing is provided with a recessed portion that is positioned to fit into the tip end portion of the protrusion that protrudes in the width direction of the housing, thereby preventing an increase in the thickness of the portion of the housing that overlaps with the tip end portion of the protrusion. This prevents an increase in the thickness of the housing, and advantageously achieves a low profile for the electrical connector.
[0015] (4) The electrical connector further includes a reinforcing tab that is press-fit into the housing and fixed to the board, thereby fixing the housing to the board. The reinforcing tab has a board fixing portion that is fixed to the board, a housing press-fit portion that is press-fit into the housing, and a tab connecting portion that connects the board fixing portion and the housing press-fit portion. The reinforcing tab has a tab protrusion that protrudes and extends along a direction perpendicular to the thickness direction of the housing from a board-side tab connecting portion that is a portion of the tab connecting portion that is continuous with the board fixing portion, and the tab protrusion may be positioned so that a tip side portion that protrudes from the board-side tab connecting portion overlaps with the housing in the thickness direction of the housing.
[0016] A notch formed by cutting out an edge of the housing may be provided on the edge of the housing to provide an area for accommodating a reinforcement tab that is press-fitted into the housing and fixed to a board. Because the housing is disposed in a through-hole in the board, if the notch is provided on the edge of the housing, when a light source is located near the board, light leaks from an area adjacent to the notch provided on the edge of the housing that passes through the through-hole in the board. However, with the above configuration, the reinforcement tab is provided with a tab protrusion that protrudes in a direction perpendicular to the thickness direction of the housing from a board-side tab connection portion that is a portion of the tab connection portion that connects the housing press-fit portion and the board fixing portion that is continuous with the board fixing portion. The tab protrusion is positioned so that a tip end portion protruding from the board-side tab connection portion overlaps with the housing in the thickness direction of the housing. Therefore, even if a notch is provided on the edge of the housing to provide an area for accommodating the reinforcement tab, the area adjacent to the notch can be covered and blocked by the tab protrusion in the thickness direction of the housing. This prevents light from leaking to the outside through the area adjacent to the notch provided on the edge of the housing that passes through the through hole in the board, even if the light source is located near the board. [Effects of the Invention]
[0017] According to the present invention, it is possible to provide an electrical connector that can prevent light from leaking through gaps in the housing of the electrical connector that passes through a through-hole in a board. [Brief explanation of the drawings]

FIGS. 5 and 6 are perspective views of the electrical connector 1, showing the electrical connector 1 as seen from different directions.
[0021] The electrical connector 1 shown in FIGS. 1 to 8 is configured as an electrical connector that is mounted on a substrate 100 by being connected to the substrate 100. The substrate 100 to which the electrical connector 1 is connected is provided, for example, as part of a backlight device (not shown) for a liquid crystal panel of a liquid crystal display device, and is arranged on the back side of the liquid crystal panel of the liquid crystal display device. The electrical connector 1 connected to the substrate 100 can be applied to various devices, not limited to backlight devices. The electrical connector 1 is connected to a mating connector (not shown) while connected to the substrate 100. The mating connector is mated with the electrical connector 1, thereby connecting the electrical connector 1 and the mating connector.
[0022] 1 to 4, the substrate 100 to which the electrical connector 1 is connected is configured as a substrate having an insulating layer on the surface of a metal plate formed using a metal material with excellent thermal conductivity, such as aluminum, and a conductive circuit pattern further provided on the surface of the insulating layer. The conductive circuit pattern is provided, for example, on the front surface 100a of the substrate 100. Note that the conductive circuit pattern is not shown in FIGS. 1 to 3. The conductive circuit pattern provided on the front surface 100a of the substrate 100 is provided with conductive portions 100c to which the contacts 12 of the electrical connector 1 are electrically connected by soldering. The substrate 100 also has a through hole 100d through which the electrical connector 1 is disposed. The through hole 100d is opened in a substantially rectangular shape corresponding to the outer shape of the housing 11 of the electrical connector 1 and is provided as a hole penetrating the substrate 100 from the front surface 100a to the back surface 100b of the substrate 100.
[0023] 1 to 8, an electrical connector 1 is configured to include a housing 11, a plurality of contacts 12, and reinforcing tabs (13, 14).
[0024] The housing 11 is made of an insulating resin material, and is placed on the substrate 100 with the housing 11 passing through a through-hole 100d provided in the substrate 100. The housing 11 is configured so that a plurality of contacts 12 are inserted into it and the housing 11 holds the inserted plurality of contacts 12. The housing 11 holds the plurality of contacts 12 with the plurality of contacts 12 lined up in a row.
[0025] Each of the plurality of contacts 12 is formed of a conductive metal material and configured to be inserted into the housing 11 along a predetermined insertion direction and held by the housing 11. Each contact 12 is connected to the board 100 while held by the housing 11. Specifically, each contact 12 held by the housing 11 is soldered to a conductive portion 100c on the surface 100a of the board 100 with the housing 11 passing through a through-hole 100d in the board 100 and placed on the board 100. This electrically and mechanically connects the contacts 12 to the board 100. Furthermore, when a mating connector (not shown) is mated and connected to the electrical connector 1, the contacts 12 come into contact with and are electrically connected to mating contacts (not shown) held in the mating connector. The insertion direction of the contacts 12 into the housing 11 is set perpendicular to the thickness direction of the housing 11. The direction of insertion of the contacts 12 into the housing 11 is set to be parallel to the surface 100a of the substrate 100 with the housing 11 passing through the through-holes 100d.
[0026] The reinforcing tabs 13 and 14 are provided as members that are press-fitted into the housing 11 and fixed to the board 100, thereby fixing the housing 11 to the board 100. The reinforcing tabs (13, 14) are made of a metal material, and the reinforcing tabs (13, 14) that are press-fitted into the housing 11 are fixed to the board 100 by soldering.
[0027] The configuration of the electrical connector 1 will be described in more detail below. In the following description, the insertion direction X1, thickness direction X2, and width direction X3 of the electrical connector 1 are defined as shown by double-ended arrows X1, X2, and X3 in FIGS. 1 to 7 and the following drawings. The insertion direction X1 is defined as a direction parallel to the direction in which the contacts 12 are inserted into the housing 11 of the electrical connector 1. The insertion direction X1 is defined as a direction parallel to the surface 100a of the board 100 when the housing 11 is disposed on the board 100, passing through the through-hole 100d of the board 100. The insertion direction X1 is also defined as a direction perpendicular to the thickness direction X2 of the electrical connector 1. The thickness direction X2 of the electrical connector 1 also defines the thickness direction X2 of the housing 11, which constitutes the basic outer shape of the electrical connector 1, and is defined as a direction perpendicular to the insertion direction X1. The housing 11 is formed to have a basic outer shape of a thin rectangular parallelepiped with a small dimension in the thickness direction X2. The width direction X3 of the electrical connector 1 is also defined as the width direction X3 of the housing 11, and is defined as a direction perpendicular to the thickness direction X2 and the insertion direction X1 of the housing 11. The width direction X3 of the housing 11 corresponds to the direction in which the multiple contacts 12 held side by side in the housing 11 are arranged in the housing 11.
[0028] [housing] Fig. 9 is a perspective view showing the housing 11 of the electrical connector 1. Fig. 10 is a perspective view of the housing 11. Fig. 11 is a plan view of the housing 11. Referring to Figs. 1 to 11, the housing 11 is formed of an insulating resin material, holds a plurality of contacts 12, and is configured to be placed on the board 100 with the contacts 12 passing through through holes 100d in the board 100. The housing 11 has a housing main body 21 having a basic external shape of a substantially rectangular parallelepiped, and a top plate 22 provided integrally with the housing main body 21 at one end of the housing main body 21 in the thickness direction X2.
[0029] 2 and 3, the housing main body 21 of the housing 11 is disposed relative to the substrate 100, passing through the through hole 100d of the substrate 100. The outer shape of the cross section of the housing main body 21 perpendicular to the thickness direction X2 is formed to correspond to the shape of the through hole 100d of the substrate 100, and the housing main body 21 is disposed inside the through hole 100d so as to fit into and close the through hole 100d. Also, referring to FIGS. 2, 3, and 5 to 10, the housing main body 21 is provided with a plurality of contact insertion grooves 23 and fitting holes 24.
[0030] 2 and 5 to 10, the contact insertion grooves 23 are provided as grooves into which the contacts 12 are inserted and held, respectively. The contact insertion grooves 23 are provided as grooves that open on one side of the housing main body 21 in the insertion direction X1 and extend along the insertion direction X1 within the housing main body 21. The contact insertion grooves 23 are provided side by side in the width direction X3 of the housing 11, and each contact insertion groove 23 is configured so that the corresponding contact 12 is inserted along the insertion direction X1.
[0031] Referring to FIG. 3 , the mating hole 24 is provided as a hole into which a mating connector (not shown) is mated to be connected to the electrical connector 1 connected to the board 100. The mating hole 24 is provided as a hole that opens on the other side of the housing main body 21 in the insertion direction X1 and extends along the insertion direction X1. That is, the mating hole 24 opens on the other side of the housing main body 21 in the insertion direction X1, which is opposite to the side in the insertion direction X1 where the contact insertion grooves 23 open, and extends within the housing main body 21 along the insertion direction X1. The mating hole 24 is also provided as a hole that widens along the width direction X3. When a mating connector is connected to the electrical connector 1, an end of the mating connector is inserted into the mating hole 24, and the mating connector is mated with the housing 11. The mating hole 24 communicates with the plurality of contact insertion grooves 23 inside the housing main body 21. When the mating connector is mated with the mating hole 24, the mating contact in the mating connector comes into contact with the contact 12 inserted and held in the contact insertion groove 23 of the housing 11, and the contact 12 and the mating contact are electrically connected.
[0032] 1 and 4 to 11, the top plate portion 22 of the housing 11 is provided as a flat, plate-like portion at one end of the housing main body 21 in the thickness direction X2, and is provided integrally with the housing main body 21. The dimensions of the cross section of the top plate portion 22 perpendicular to the thickness direction X2 are larger in the insertion direction X1 and the width direction X3 than the dimensions of the cross section of the housing main body 21 perpendicular to the thickness direction X2. The dimensions of the cross section of the top plate portion 22 perpendicular to the thickness direction X2 are larger in the insertion direction X1 and the width direction X3 than the dimensions of the opening shape of the through hole 100d of the board 100. Therefore, when the housing main body 21 is disposed on the board 100, passing through the through hole 100d of the board 100, the top plate portion 22 is disposed to entirely cover and block the through hole 100d of the board 100 (see FIG. 4).
[0033] 6 to 11, the top plate portion 22 has a plurality of notches 25 formed in an edge portion on one side in the insertion direction X1. The plurality of notches 25 are formed in the edge portion of the top plate portion 22 at positions corresponding to the plurality of contact insertion grooves 23 formed in the housing main body 21. Each of the plurality of notches 25 is formed as a thin slit-shaped portion cut out from the edge portion of the top plate portion 22 along the insertion direction X1. By providing the notches 25 in the edge portion of the top plate portion 22 of the housing 11, gaps 26 are formed in the edge portion of the top plate portion 22, penetrating the edge portion of the top plate portion 22 in the thickness direction X2 of the housing 11. The gaps 26 formed by providing the notches 25 are slit-shaped gaps. Furthermore, the plurality of gaps 26 formed by providing the plurality of notches 25 are respectively connected to the plurality of contact insertion grooves 23. When the contact 12 is inserted into the contact insertion groove 23 in the insertion direction X1, a connecting portion 32 (described later) that connects a housing insertion portion 31 (described later) of the contact 12 with a board connection portion 30 (described later) passes through the gap 26. In other words, the gap 26 formed by providing the notch 25 constitutes an area through which the connecting portion 32 that connects the housing insertion portion 31 of the contact 12 with the board connection portion 30 passes when the contact 12 is inserted into the housing 11.
[0034] 6 to 11, the top plate 22 is provided with a plurality of insulating portions 27 at an edge portion on one side in the insertion direction X1. The plurality of insulating portions 27 are provided at the edge portion of the top plate 22 at positions corresponding to the plurality of contact insertion grooves 23 provided in the housing main body 21. Each of the plurality of insulating portions 27 is provided adjacent to a corresponding one of the plurality of cutout portions 25 in the width direction X3. Each of the plurality of insulating portions 27 is formed as a plate-like portion extending on one side in the insertion direction X1 at the edge portion of the top plate 22, and is provided so as to protrude in a plate-like manner toward one side in the insertion direction X1 beyond the end of the housing main body 21 on one side in the insertion direction X1.
[0035] When the contact 12 is inserted into the contact insertion groove 23 in the insertion direction X1, the insulating portion 27 is disposed between the substrate 100 and a board-side connecting portion 32a, which is the portion of the connecting portion 32 of the contact 12 on the board connection portion 30 side, described below. By disposing the insulating portion 27 between the substrate 100 and the board-side connecting portion 32a of the connecting portion 32 of the contact 12, described below, the insulation distance between the contact 12 and the inner periphery of the through hole 100d in the substrate 100 can be increased. Note that if the substrate 100 is formed by providing an insulating layer and a conductive circuit pattern on the surface of a metal plate, the metal material will be exposed at the inner periphery of the through hole 100d in the substrate 100. However, by arranging the insulating portion 27 provided as part of the housing 11 formed of an insulating resin material between the board side connecting portion 32a of the connecting portion 32 in the contact 12 and the board 100, the creepage distance between the board side connecting portion 32a of the connecting portion 32 in the contact 12 and the inner portion of the through hole 100d in the board 100 can be increased, thereby making it possible to increase the insulation distance.
[0036] 6 to 11, the top plate portion 22 is provided with a plurality of recessed portions 28 on one edge portion in the insertion direction X1. The plurality of recessed portions 28 are provided on the edge portion of the top plate portion 22 at positions corresponding to the plurality of contact insertion grooves 23 provided in the housing main body 21. Each of the plurality of recessed portions 28 is provided adjacent to a corresponding one of the plurality of cutout portions 25 in the width direction X3. The recessed portions 28 are provided adjacent to the cutout portions 25 on the opposite side of the insulating portion 27 in the width direction X3. The recessed portions 28 provided adjacent to the cutout portions 25 in the width direction X3 are formed so that part of the edge portion of the top plate portion 22 is recessed in a stepped shape in the thickness direction X2. When the contact 12 is inserted into the contact insertion groove 23 of the housing 11, the tip end portion of the protrusion 33, which protrudes from the board side connecting portion 32a of the connecting portion 32 described below in the contact 12, is positioned so as to fit into the recessed portion 28.
[0037] 1, 4, 5, 8, 9, and 11, the top plate portion 22 is provided with tab placement notches 29 cut out at the edge portions on both end sides in the width direction X3 so as to open toward the other side in the insertion direction X1. That is, the top plate portion 22 is provided with tab placement notches 29 cut out at the edge portions on both end sides in the width direction X3 so as to open toward the other side in the insertion direction X1, which is the side on which the fitting hole 24 opens in the insertion direction X1. The tab placement notches 29 are provided by cutting out the edge portions of the top plate portion 22 to provide areas on both end sides of the housing 11 where the reinforcing tabs 13, which are press-fitted into and attached to the housing 11, are to be placed.

Therefore, the insulating portion 27 of the housing 11 is disposed between the board-side connecting portion 32a and the board 100.
[0048] The insertion-side connecting portion 32b is provided as a portion of the connecting portion 32 that is continuous with the housing insertion portion 31. That is, the insertion-side connecting portion 32b is provided as a portion of the connecting portion 32 that is continuous with the press-fit fixing portion 31a and the mating connection portion 31b of the housing insertion portion 31. The insertion-side connecting portion 32b is formed in a plate shape that widens in a direction perpendicular to the width direction X3 and extends in the thickness direction X2. The press-fit fixing portion 31a is provided continuous with the insertion-side connecting portion 32b at one end of the insertion-side connecting portion 32b in the thickness direction X2 and integral with the insertion-side connecting portion 32b. The mating connection portion 31b is provided continuous with the insertion-side connecting portion 32b at the other end of the insertion-side connecting portion 32b in the thickness direction X2 and integral with the insertion-side connecting portion 32b. When the contact 12 is inserted and held in the housing 11, the insertion side connecting portion 32b is inserted into the contact insertion groove 23 of the housing main body portion 21 of the housing 11 and is positioned in the contact insertion groove 23.
[0049] The bent portion 32c is provided as a portion that integrally connects the board-side connecting portion 32a and the insertion-side connecting portion 32b, and is provided so as to bend in an arc shape over approximately 90° from the width direction X3 to the thickness direction X2. The bent portion 32c is provided so as to be continuous with the board-side connecting portion 32a at an end portion facing the width direction X3 and be continuous with the board-side connecting portion 32a, and is provided so as to be continuous with the insertion-side connecting portion 32b at an end portion facing the thickness direction X2 and be continuous with the insertion-side connecting portion 32b. When the contact 12 is inserted into the housing 11, the bent portion 32c of the connecting portion 32 passes through the gap 26 formed by the notch 25 provided in the top plate portion 22 (see FIGS. 7, 15, and 16).
[0050] 1, 4, 5, 7, 8, and 12 to 16, the protrusion 33 provided on the contact 12 extends from the board-side connecting portion 32a in a direction perpendicular to the thickness direction X2 of the housing 11, and also protrudes from the board-side connecting portion 32a in the width direction X1 of the housing 11. The protrusion 33 is provided to protrude from the board-side connecting portion 32a at a position adjacent to the bent portion 32c in the insertion direction X1. The protrusion 33 is also provided to extend in a plate-like shape from the board-side connecting portion 32a in a direction perpendicular to the thickness direction X2 of the housing 11.
[0051] 6, 7, and 13 to 16, the protruding portion 33 extends in a plate shape from the board-side connecting portion 32a in a direction perpendicular to the thickness direction X2 of the housing 11 and protrudes in the width direction X3 of the housing 11. The protruding portion 33 is disposed so that a tip end portion protruding in the width direction X3 of the housing 11 overlaps the housing 11 in the thickness direction X2 of the housing 11. More specifically, the protruding portion 33 is disposed so that a tip end portion protruding in the width direction X3 of the housing 11 overlaps the recessed portion 28 of the top plate portion 22 of the housing 11 in the thickness direction X2 of the housing 11. The protruding portion 33 is disposed so that a tip end portion protruding in the width direction X3 of the housing 11 fits into the recessed portion 28 provided in the top plate portion 22 of the housing 11. When the tip end portion of protrusion 33 protruding in width direction X3 is positioned to fit into recessed portion 28 and overlaps recessed portion 28 in thickness direction X2, gap 26 formed by notch 25 in top plate 22 is covered by protrusion 33 and is blocked in thickness direction X2. Therefore, even when the light source is located near substrate 100, light is prevented from leaking to the outside through gap 26 at the edge of top plate 22 of housing 11 that penetrates through hole 100d of substrate 100.
[0052] Reinforcement tab Figures 17(A) and 17(B) are perspective views showing the reinforcing tab 13 of the electrical connector 1. Figure 18 is an enlarged perspective view of a portion of the electrical connector 1. Note that Figure 18 is an enlarged perspective view of a portion of one end of the electrical connector 1 in the width direction X3. With reference to Figures 1, 4 to 6, 8, 14, 17, and 18, the electrical connector 1 is provided with reinforcing tabs (13, 14). The reinforcing tabs (13, 14) are made of a metal material and are provided to fix the housing 11 to the board 100 by being press-fitted into the housing 11 and fixed to the board 100 by soldering.
[0053] The reinforcing tabs 13 are provided in pairs and are press-fitted into the housing 11 at both end sides in the width direction X3 to fix the housing 11 to the substrate 100 at both end sides in the width direction X3. Fig. 17(A) is a perspective view of the reinforcing tab 13 press-fitted into the housing 11 at one end side of the housing 11 in the width direction X3, and Fig. 17(B) is a perspective view of the reinforcing tab 13 press-fitted into the housing 11 at the other end side of the housing 11 in the width direction X3. The reinforcing tab 14 is press-fitted into the housing 11 at the center side of the housing 11 in the width direction X3 to fix the housing 11 to the substrate 100.
[0054] The reinforcing tab 14 press-fitted into the housing 11 at the center of the housing 11 in the width direction X3 is press-fitted into the housing 11 at a portion where no notch is provided on the edge of the top plate portion 22 of the housing 11. Therefore, when the electrical connector 1 is connected to the board 100, the top plate portion 22 of the housing 11 covers the through hole 100d of the board 100 in the thickness direction X2 in the region of the housing 11 near the portion where the reinforcing tab 14 is press-fitted. On the other hand, the reinforcing tabs 13 press-fitted into the housing 11 at both ends of the housing 11 in the width direction X3 are press-fitted into the housing 11 at a portion where the tab placement notch 29 is provided on the edge of the top plate portion 22 of the housing 11. The reinforcing tabs 13 are press-fitted into the housing 11 at both ends in the width direction X3 of the housing 11 at portions where the tab placement notches 29 are provided on the edges of the top plate 22, so that the reinforcing tabs 13 can be press-fitted and positioned at both ends in the width direction X3 of the housing 11 while preventing the electrical connector 1 from becoming too large in size in the width direction X3. The configuration of the reinforcing tabs 13 will be described in more detail below.
[0055] 1, 4 to 6, 8, 14, 17, and 18, the reinforcing tab 13 includes a board fixing portion 34, a housing press-fit portion 35, a tab connecting portion 36, and a tab protruding portion 37. The board fixing portion 34, the housing press-fit portion 35, the tab connecting portion 36, and the tab protruding portion 37 are integrally formed.
[0056] The board fixing portion 34 of the reinforcing tab 13 is provided as a portion that is soldered and fixed to the board 100. The board fixing portion 34 is provided as a portion that extends in a plate shape at one end of the reinforcing tab 13 in the width direction X3 when the reinforcing tab 13 is press-fitted into the housing 11. The board fixing portion 34 is fixed to the board 100 by being soldered to the surface 100a of the board.
[0057] The housing press-fit portion 35 of the reinforcing tab 13 is provided as a portion to be press-fitted into the housing 11. The housing press-fit portion 35 is configured to be press-fitted into the housing 11 at a portion of the housing 11 where the tab placement notch 29 is provided. A press-fit hole (not shown) into which the housing press-fit portion 35 is press-fitted is opened at the portion of the housing 11 where the tab placement notch 29 is provided. The press-fit hole is provided as a hole extending along the insertion direction X1. The housing press-fit portion 35 is provided in a plate shape extending along the insertion direction X1, and in this embodiment, a tip side portion extending along the insertion direction X1 is provided in a pair of fork shapes. The housing press-fit portion 35 is press-fitted along the insertion direction X1 into the press-fit hole that opens at the portion of the housing 11 where the tab placement notch 29 is provided. By press-fitting the housing press-fit portion 35 into the housing 11, the reinforcing tab 13 is fixed and attached to the housing 11.
[0058] 1, 4 to 6, 8, 14, 17, and 18, the tab connecting portion 36 of the reinforcing tab 13 is provided as a portion that integrally connects the board fixing portion 34 and the housing press-fit portion 35. The tab connecting portion 36 has a board-side tab connecting portion 36a, a press-fit side tab connecting portion 36b, and a bent portion 36c that are integrally provided, and is configured to connect the board fixing portion 34 and the housing press-fit portion 35.
[0059] The board-side tab connecting portion 36a is provided as a portion of the tab connecting portion 36 that is continuous with the board fixing portion 34. The board-side tab connecting portion 36a is formed in a plate shape that extends along a direction perpendicular to the thickness direction X2, and is provided integrally with the board fixing portion 34. When the reinforcing tab 13 is press-fitted into the housing 11, the board-side tab connecting portion 36a is located in an area defined by the tab placement notch 29 in the housing 11, and is located adjacent to one end of the housing main body 21 in the thickness direction X2.
[0060] The press-fit-side tab connecting portion 36b is provided as a portion of the tab connecting portion 36 that is continuous with the housing press-fit portion 35. The press-fit-side tab connecting portion 36b is formed in a plate shape that extends along a direction perpendicular to the thickness direction X2, and is provided integrally with the housing press-fit portion 35. When the reinforcing tab 13 is press-fitted into the housing 11, the press-fit-side tab connecting portion 36b is inserted in the insertion direction X1 into a press-fit hole that opens at a portion of the housing 11 where the tab placement notch 29 is provided.
[0061] The bent portion 36c is provided as a portion that integrally connects the board-side tab connecting portion 36a and the press-fitting-side tab connecting portion 36b. The board-side tab connecting portion 36a and the press-fitting-side tab connecting portion 36b are arranged in a stepped manner with their positions shifted in the thickness direction X1. The bent portion 36c extends while bending from the board-side tab connecting portion 36a to the press-fitting-side tab connecting portion 36b, integrally connecting the board-side tab connecting portion 36a and the press-fitting-side tab connecting portion 36b, which are positioned in a stepped manner in the thickness direction X1.
[0062] 1, 4, 5, 8, 14, 17, and 18, the tab protrusion 37 provided on the reinforcing tab 13 is provided to protrude and extend from the board-side tab connecting portion 36a in a direction perpendicular to the thickness direction X2 of the housing 11. The tab protrusion 37 is provided to extend in a plate shape from the board-side tab connecting portion 36a in a direction perpendicular to the thickness direction X2 of the housing 11. The tab protrusion 37 protrudes from the board-side tab connecting portion 36a in the direction perpendicular to the thickness direction X2 of the housing 11, and is disposed such that a tip end portion of the tab protrusion 37 protruding from the board-side tab connecting portion 36a overlaps an edge of the top plate portion 22 of the housing 11 in the thickness direction X2 of the housing 11. More specifically, a tip end portion of the tab protrusion 37 protruding in a plate shape from the board-side tab connection portion 36a is disposed so as to overlap an edge portion of a portion of the top plate portion 22 of the housing 11 where the tab placement notch 29 is provided, in the thickness direction X2 of the housing 11. When the tip end portion of the tab protrusion 37 protruding from the board-side tab connection portion 36a overlaps an edge portion of a portion of the top plate portion 22 where the tab placement notch 29 is provided, in the thickness direction X2, an area adjacent to the tab placement notch 29 is covered and blocked in the thickness direction X2 by the tab protrusion 37. Therefore, even if the light source is located near the board 100, light is prevented from leaking to the outside through an area adjacent to the tab placement notch 29 provided on the edge portion of the top plate portion 22 of the housing 11 that penetrates the through-hole 100d of the board 100.
[0063] [Actions and Effects of This Embodiment] According to this embodiment, the housing 11 of the electrical connector 1 is disposed on the board 100 while passing through the through-hole 100d of the board 100, which allows the overall thickness of the board 100 and the electrical connector 1 attached to the board 100 to be reduced, thereby enabling the overall structure of the board 100 and the electrical connector 1 to be made low-profile. Furthermore, according to this embodiment, the insertion direction X1 of the contacts 12, in which the contacts 12 are inserted into the housing 11, is set to be perpendicular to the thickness direction X2 of the housing 11 and parallel to the surface 100a of the board 100 when the housing 11 passes through the through-hole 100d of the board 100. This prevents variations in the contact positions between the contacts 12 and the surface 100a of the board 100 in the thickness direction X2 of the housing 11.
[0064] According to the present embodiment, the contact 12 is provided with a protrusion 33 that extends from a board-side connecting portion 32a, which is a portion of the connecting portion 32 that connects the housing insertion portion 31 and the board connecting portion 30 and that is continuous with the board connecting portion 30, along a direction perpendicular to the thickness direction X2 of the housing 11 and protrudes in the width direction X3 of the housing 11. The protrusion 33 is arranged such that a tip portion of the protrusion 33 that protrudes in the width direction X2 of the housing 11 overlaps with an edge portion of the top plate 22 of the housing 11 in the thickness direction X2 of the housing 11. Therefore, even if a gap 26 that penetrates the housing 11 in the thickness direction X2 of the housing 11 is formed at the edge of the top plate 22 of the housing 11, by cutting out a notch 25, the notch 25 can be formed at the edge of the top plate 22 of the housing 11. This allows the protrusion 33 to cover and close the gap 26 in the thickness direction X2 of the housing 11. This prevents light from leaking to the outside through the gap 26 at the edge of the top plate portion 22 of the housing 11 that passes through the through hole 100d of the substrate 100, even if the light source is located near the substrate 100.
[0065] As described above, according to this embodiment, an electrical connector 1 can be provided that can prevent light from leaking through the gap 26 in the housing 11 of the electrical connector 1 that passes through the through hole 100d of the substrate 100.
[0066] Furthermore, according to this embodiment, the protrusion 33 extends in a plate-like shape from the board-side connecting portion 32a along a direction perpendicular to the thickness direction X2 of the housing 11, and therefore can efficiently cover and seal the gap 26 at the edge of the top plate portion 22 of the housing 11, thereby more effectively preventing light leakage.
[0067] Furthermore, according to this embodiment, the top plate 22 of the housing 11 is provided with the recessed portion 28 that is arranged to fit into the tip end portion of the protruding portion 33 that protrudes in the width direction X3 of the housing 11, thereby preventing an increase in the thickness of the portion of the housing 11 that overlaps with the tip end portion of the protruding portion 33. This prevents an increase in the dimension of the housing 11 in the thickness direction X2, and allows the electrical connector 1 to be suitably low-profile.
[0068] In this embodiment, reinforcing tabs 13 are provided on both ends of the housing 11 in the width direction X3 to be press-fitted into the housing 11, and both ends of the housing 11 in the width direction X3 are fixed to the board 100 by the reinforcing tabs 13, so that the housing 11 can be stably and firmly fixed to the board 100. In this embodiment, tab placement notches 29 are provided on the edge of the top plate 22 of the housing 11 by cutting out an edge of the top plate 22 of the housing 11 to provide an area on the housing 11 to place the reinforcing tabs 13 that are press-fitted into the housing 11 and fixed to the board 100 on both ends of the housing 11 in the width direction X3. Since tab placement notches 29 for placing reinforcing tabs 13 press-fitted into housing 11 at both ends of housing 11 in the width direction X3 are provided at the edge of top plate 22 of housing 11, reinforcing tabs 13 can be press-fitted and positioned at both ends of housing 11 in the width direction X3 while preventing the electrical connector 1 from becoming larger in size in the width direction X3. Meanwhile, since housing 11 is placed in through hole 100d of substrate 100, if tab placement notches 29 are provided at the edge of top plate 22 of housing 11, when a light source is located near substrate 100, light will leak from an area adjacent to tab placement notches 29 provided at the edge of top plate 22 of housing 11 that passes through through hole 100d of substrate 100. However, according to the present embodiment, the reinforcement tab 13 is provided with a tab protrusion 37 that protrudes from a board-side tab connecting portion 36a, which is a portion of the tab connecting portion 36 that connects the housing press-fit portion 35 and the board fixing portion 34 and that is continuous with the board fixing portion 34, along a direction perpendicular to the thickness direction X2 of the housing 11. The tab protrusion 37 is disposed such that the tip end portion that protrudes from the board-side tab connecting portion 36a overlaps with the top plate portion 22 of the housing 11 in the thickness direction X2 of the housing 11. Therefore, even if a tab placement notch 29 is provided in an edge portion of the top plate portion 22 of the housing 11 to provide an area for placing the reinforcement tab 13 on the housing 11, the area adjacent to the tab placement notch 29 can be covered and blocked by the tab protrusion 37 in the thickness direction X2 of the housing 11.This prevents light from leaking to the outside through the area adjacent to the tab placement notch 29 provided on the edge of the top plate portion 22 of the housing 11 that passes through the through hole 100d of the substrate 100, even if the light source is located near the substrate.
[0069] [Variations] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and various modifications are possible within the scope of the claims. For example, the following modifications may be made.
[0070] In the above embodiment, an example has been described in which a mating connector is mated with and connected to the electrical connector 1 connected to the substrate 100, but this is not the only possible configuration. A configuration in which a flexible substrate or a flexible flat cable is connected to the electrical connector 1 connected to the substrate 100 may also be implemented. In this case, the mating connection portion 31b of the contact 12 is provided as a spring contact portion to facilitate stable contact with the conductor of the flexible substrate or flexible flat cable.
[0071] In the above-described embodiment, the protrusion 33 protruding from the board-side connecting portion 32a in the width direction X3 of the housing 11 protrudes from the board-side connecting portion 32a toward one side in the width direction X3, but this is not necessarily the case. The protrusion 33 protruding from the board-side connecting portion 32a in the width direction X3 of the housing 11 may protrude toward both sides in the width direction X3 from the board-side connecting portion 32a.
