Description

Technical Field

[0001] The present invention relates to a connector and a connector connection structure that are attached to a housing that accommodates electric equipment such as electrical equipment including a motor or power supply equipment including a battery, and that are connected to an electric circuit leading to the electrical equipment.

Background Art

[0002] Electrical equipment installed in automobiles and the like is connected to other electrical equipment such as another electrical device or a power supply device via a wire harness formed by bundling covered electric wires. In this case, the wire harness and the electrical device are connected via connectors respectively attached thereto. For example, a harness-side connector as disclosed in Patent Document 1 is connected to a device-side connector provided in a device such as a motor.

[0003] Specifically, by fitting and fixing the harness-side connector to the device-side connector provided in a device such as a motor, a connection terminal provided on the harness-side connector is connected to a connection terminal provided on the device-side connector, so that the harness-side connector and the device-side connector are conductively connected to each other.

[0004] The device-side connector described above is attached to a housing having an electric device provided therein, and the connection terminal is connected to an electric circuit leading to the electric device arranged inside. By bending the distal end side portion of the connection terminal, to which the electric circuit is connected, outward, the connection terminal and the electric circuit can be connected through a connection operation performed from the same direction.

[0005] Such a device-side connector is attached by being inserted into a mounting hole provided in the housing. However, in order to insert and attach the device-side connector into the mounting hole provided in the housing ru , it is necessary to pass the outwardly bent distal end portion through the mounting hole, which requires an increase in the diameter of the mounting hole. When the diameter of the mounting hole is increased, the portion of the device-side connector inserted into the mounting hole also increases in diameter in accordance with the mounting hole, resulting in an increase in the size of the connector.

[0006] [Patent Document 1] Japanese Patent Publication No. 2018-181404 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] The present invention aims to provide a connector and a connector connection structure that can efficiently connect to electrical circuits provided inside a housing without increasing its size. [Means for solving the problem]

[0008] This invention relates to a connector that mates with a mating connector to connect terminals provided on each, comprising at least two connection terminals, a connector housing that houses at least a portion of the connection terminals and is fixed to a housing, the connector housing is provided with an insertion mounting portion that is inserted into a mounting hole provided in the housing, the connection terminals comprising a terminal connection portion that connects to the connection terminals of the mating connector, a circuit connection portion that is located inside the housing and connects to an electrical circuit provided inside the housing, and a connecting portion that connects the terminal connection portion and the circuit connection portion, the connecting portion extending along the insertion direction through which the insertion mounting portion is inserted into the mounting hole, the circuit connection portion being arranged along a direction in which the circuit connection portions are separated from each other and intersects the connecting portion, and being formed with a length such that its tip protrudes beyond the outer shape of the insertion mounting portion when viewed from the insertion direction, and at least one of the circuit connection portions of the plurality of connection terminals being arranged at different positions in the insertion direction The distance in the insertion direction between the circuit connection portions, which are positioned at different locations in the insertion direction, is set to be wider than the thickness of the housing in which the mounting hole is provided, the length in the intersecting direction between the tips of the circuit connection portions is longer than the diameter of the mounting hole, and the length in the intersecting direction between the circuit connection portion of one connection terminal with a shorter connecting portion and the connecting portion of the other connection terminal with a longer connecting portion is set to be shorter than the diameter of the mounting hole. It is characterized by the following.

[0009] Furthermore, this invention relates to a connector connection structure for connecting two or more terminals provided on each of a first connector and a second connector by mating them together, wherein the first connector comprises two or more wires with first connection terminals attached to their ends, and a housing which is a metal shell in which the first connection terminals are disposed inside, and the second connector comprises at least two second connection terminals, and a connector housing which is fixed to the housing and in which at least a part of the second connection terminals are disposed inside, and the connector housing is provided with an insertion mounting portion which is inserted into a mounting hole provided in the housing, and the second connection terminal is the first connection of the first connector The device includes a terminal connection portion for connecting to a terminal, a circuit connection portion disposed inside the housing and connected to an electrical circuit provided inside the housing, and a connecting portion for connecting the terminal connection portion and the circuit connection portion. The connecting portion extends along the insertion direction through which the insertion mounting portion is inserted into the mounting hole. The circuit connection portion is arranged along a direction in which the circuit connection portions are separated from each other and intersects the connecting portion, and is formed to a length such that its tip protrudes beyond the outer shape of the insertion mounting portion when viewed from the insertion direction. At least one of the circuit connection portions of the plurality of second connection terminals is arranged at a different position in the insertion direction. The distance in the insertion direction between the circuit connection portions, which are positioned at different locations in the insertion direction, is set to be wider than the thickness of the housing in which the mounting hole is provided, the length in the intersecting direction between the tips of the circuit connection portions is longer than the diameter of the mounting hole, and the length in the intersecting direction between the circuit connection portion of one connection terminal with a shorter connecting portion and the connecting portion of the other connection terminal with a longer connecting portion is set to be shorter than the diameter of the mounting hole. It is characterized by this.

[0010] The arrangement of the circuit connection portions in a direction that separates them from each other and intersects the connecting portion includes the arrangement of the circuit connection portions in a direction perpendicular to the connecting portion, or in a direction that intersects it at an acute or obtuse angle. The circuit connection portions may be in the same direction, that is, parallel, or in different directions.

[0011] This invention allows for efficient connection to electrical circuits located within the housing without increasing its size. More specifically, the connector (second connector) mates with a mating connector (first connector) to connect the terminals provided on each, and at least two connection terminals (second connection terminals), at least a portion of which are located inside the connector housing fixed to the housing, are provided with a terminal connection portion that connects to the connection terminal (first connection terminal) of the mating connector (first connector), a circuit connection portion that is located inside the housing and connects to an electrical circuit provided inside the housing, and a connecting portion that connects the terminal connection portion and the circuit connection portion. The connecting portion extends along the insertion direction through which the insertion mounting portion is inserted into the mounting hole, and the circuit connection portions are arranged in a direction that separates the circuit connection portions from each other and intersects the connecting portion. Therefore, the circuit connection portions of multiple connection terminals can be arranged in a direction intersecting the insertion direction, and the electrical circuit provided inside the housing can be efficiently connected to the circuit connection portions.

[0012] Furthermore, although the circuit connection portion is formed to a length such that its tip protrudes beyond the outer shape of the insertion mounting portion when viewed from the insertion direction, at least one of the circuit connection portions of the multiple connection terminals is positioned at a different location in the insertion direction. Therefore, the circuit connection portions positioned at different locations in the insertion direction can be inserted into the mounting hole one by one. Consequently, the diameter of the mounting hole only needs to be large enough to allow one circuit connection portion and the connecting portion of another connection terminal to pass through, and the diameter of the mounting hole can be reduced compared to the case where multiple circuit connection portions pass through simultaneously. Therefore, the diameter of the insertion mounting portion that fits into the mounting hole can also be reduced, and the size of the connector can be suppressed.

[0013] Furthermore, the distance in the insertion direction between the circuit connection portions, which are located at different positions in the insertion direction, is set to be wider than the thickness of the housing in which the mounting holes are provided. With this configuration, when one circuit connection is inserted through the mounting hole, the other circuit connection is not inserted into the mounting hole. Therefore, the insertion mounting part can be inserted into the mounting hole while avoiding each other's circuit connection parts and then installed.

[0014] In one aspect of this invention, the portion of the connecting portion that protrudes from the insertion mounting portion within the housing is defined as a protruding connecting portion, and the protruding length of the protruding connecting portion of at least one of the circuit connection portions of the plurality of connection terminals may be set to be longer than the protruding length of the protruding connecting portions of the other connection terminals.

[0015] This invention allows circuit connection portions to be positioned at different locations in the insertion direction by providing a circuit connection portion at the tip of the protruding connecting portion. Furthermore, by adjusting the length of the protruding connecting portion, the circuit connection portion can be positioned at a desired location in the insertion direction.

[0016] In another aspect of this invention, the circuit connection portions of the plurality of connection terminals may extend along an orthogonal plane perpendicular to the insertion direction at different positions in the insertion direction. This invention makes it possible to arrange circuit connection parts that are positioned at different locations in the insertion direction in parallel to each other. Therefore, electrical circuits can be connected to the circuit connection parts from the same direction.

[0017] In another aspect of this invention, the connection terminal may be made of a metal plate, and the circuit connection portion may be formed by bending it in the thickness direction relative to the connecting portion. This invention makes it possible to easily arrange the circuit connection portions in a direction that separates them from each other and intersects with respect to the connecting portion.

[0018] In another aspect of this invention, the mounting holes are provided on a metal mounting base that is attached to the housing, and the spacing between the circuit connection portions of the plurality of connection terminals in the insertion direction may be set to be wider than the thickness of the mounting base.

[0019] With this invention, when one circuit connection is inserted through the mounting hole, the other circuit connection is not inserted into the mounting hole of the mounting base. Therefore, each circuit connection can be inserted through the mounting hole without interfering with the mounting base, and the insertion mounting portion can be inserted through the mounting hole and attached to the mounting base. [Effects of the Invention]

[0020] According to the present invention, it is possible to provide a connector and a connector connection structure that can be efficiently connected to an electric circuit provided in a housing without increasing the size. [Brief Description of the Drawings]

[0026] For details, Figure 8(a) shows a front view of the equipment-side connector 10 mounted on the mounting base 70, and Figure 8(b) shows a rear view of the equipment-side connector 10 in the same state. In Figure 8(a), the through-hole 71 and circuit connection part 113 on the rear side are shown with dashed lines, and in Figure 8(b), the mounting base 70 is shown in a transparent state. Figure 9(a) shows a right side view of the equipment-side connector 10 mounted on the mounting base 70, and Figure 9(b) shows a right side view of the equipment-side connector 10 before it is mounted on the mounting base 70. In Figure 9, the mounting base 70 is shown as a vertical cross-section in the center in the width direction W.

[0027] Figure 10(a) shows a plan view of the equipment-side connector 10 when it is attached to the mounting base 70, Figure 10(b) shows a plan view of the equipment-side connector 10 before it is attached to the mounting base 70, and Figures 11(a) to 11(e) show plan views of the equipment-side connector 10 at each stage of attachment to the mounting base 70. In Figures 10 and 11, the mounting base 70 is shown as a cross-sectional view passing through the center of the through hole 71. Also, the equipment housing 60 is not shown in Figures 5 to 11.

[0028] In Figure 1(a), the vertical direction is defined as the height direction H, the direction connecting the bottom left and top right is defined as the width direction W, and the direction connecting the bottom right and top left is defined as the depth direction D. Furthermore, in the vertical direction of height H, the upper side is defined as the upper side Hu, and the lower side is defined as the lower side Hd. In addition, in the depth direction D connecting the bottom right and top left, the bottom right side is defined as the back side Db, and the top left side is defined as the front side Df.

[0029] Furthermore, for convenience in describing the configuration of the connector connection structure 1, the direction of attachment and detachment between the equipment-side connector 10 and the harness-side connector 20 is defined as the depth direction D. Also, the direction in which the harness-side connector 20 is attached to the equipment-side connector 10 is defined as the rear direction Db, and the direction in which the harness-side connector 20 is removed from the equipment-side connector 10 is defined as the front direction Df. In addition, the directions perpendicular to the depth direction D are defined as the width direction W and the height direction H. However, this does not define directions for the configuration of the equipment-side connector 10, the harness-side connector 20, and the connector connection structure 1.

[0030] The connector connection structure 1 of the present invention is a connection structure that connects the terminals provided on each (device-side terminal 11, harness-side terminal 21) by mating the harness-side connector 20 and the equipment-side connector 10. The device-side connector 10 comprises two device-side terminals 11 and a male-type housing 14 that houses at least a portion of the device-side terminals 11 and is fixed to the device housing 60. The male-type housing 14 is provided with an insertion tube portion 143 that is inserted through a through hole 71 of a mounting base 70 attached to the device housing 60.

[0031] The device-side terminal 11 includes a terminal connection portion 111 that connects to the harness-side terminal 21 of the harness-side connector 20, a circuit connection portion 113 that is located inside the device housing 60 and connects to an electrical circuit that is connected to electrical equipment provided inside the device housing 60, and a connecting portion 112 that connects the terminal connection portion 111 and the circuit connection portion 113.

[0032] The connecting portion 112 extends along the depth direction D through which the insertion cylinder portion 143 is inserted into the through hole 71. The circuit connection portions 113a and 113b are arranged in a direction that separates them from each other and intersects the connecting portion 112 along the width direction W. When viewed from the depth direction D, the tips of the connecting portions 112 are formed to protrude beyond the outer shape of the insertion cylinder portion 143. The circuit connection portions 113 of the two equipment-side terminals 11 are arranged at different positions in the depth direction D.

[0033] These connector connection structures 1, the equipment-side connector 10, and the harness-side connector 20 will be described in detail below. As shown in Figure 1, the connector connection structure 1 connects an equipment-side connector 10 to which an electrical circuit connected to electrical equipment such as motors or power supply equipment installed in automobiles, for example, to a harness-side connector 20 attached to a wire harness 200 that bundles high-voltage wires 201, and the connection state is fixed with fixing bolts 30, thereby establishing an electrically and physically stable connection state.

[0034] First, the harness-side connector 20 that constitutes the connector connection structure 1 will be explained with reference to Figures 1 to 4. The harness-side connector 20 is attached to the equipment-side connector 10 described above to form the connector connection structure 1, and is a connector that connects the equipment-side terminal 11 of the equipment-side connector 10 to the harness-side terminal 21 located inside.

[0035] The harness-side connector 20 includes a wire harness 200, harness-side terminals 21 attached to the ends of the high-voltage wires 201 that make up the wire harness 200, an internal housing 22, a housing shell 23, a housing seal 24, a housing seal cover 25, a wire seal 26, a shell seal 27, and a wire holding portion 28.

[0036] The harness-side terminal 21 is a high-voltage terminal attached to the exposed wire conductor 202 at the end of the high-voltage wire 201, which is covered with an insulating sheath 203. In the case of a wire harness 200 composed of two high-voltage wires 201, a harness-side terminal 21 is attached to each high-voltage wire 201, and the harness-side connector 20 is equipped with two harness-side terminals 21. The wire harness 200 is also covered with braided wire (not shown).

[0037] The internal housing 22 holds the two harness-side terminals 21 in predetermined positions inside the harness-side connector 20, and comprises a harness insertion tube portion 221 through which the wire harness 200 is inserted, and a holding body 222 that holds the harness-side terminals 21 provided at the ends of the wire harness 200 inserted into the harness insertion tube portion 221. The internal housing 22 is made of resin.

[0038] The harness insertion tube portion 221 is a cylindrical body with an oval shape (small oval shape) when viewed from the bottom, with the lower end (bottom end) of the lower side Hd being open, and the upper end (top end) of the upper side Hu communicating with the inside of the holding portion body 222. A through-hole 223 is provided in the center of the harness insertion tube portion 221, on the upper side Hu and in the width direction W, through which a fixing bolt 30, described later, can pass in the depth direction D.

[0039] The retaining part body 222 is positioned at the upper end Hu of the harness insertion tube portion 221, and is roughly rectangular in shape with the inner end Db open, and is configured to hold the harness-side terminal 21 inside. As shown in Figure 4, the holding unit body 222 is composed of a double wall consisting of an outer wall 222a and an inner wall 222b, and is configured to hold the harness-side terminal 21 inside the inner wall 222b.

[0040] The space between the outer wall 222a and the inner wall 222b is the space into which the hood portion 142 of the male housing 14 of the equipment-side connector 10 (described later) is inserted when the equipment-side connector 10 and the harness-side connector 20 are assembled, and the housing seal 24 is installed there.

[0041] The housing shell 23 covers the outside of the inner housing 22 and also forms the outer shape of the harness-side connector 20. The housing shell 23 is slightly larger than the inner housing 22 and includes an external harness insertion tube 231 and a shell body 232.

[0042] More specifically, the harness insertion tube exterior 231 is a cylindrical body with an oval shape when viewed from the bottom, slightly larger than the harness insertion tube portion 221, with an open end on the lower side Hd, and the upper end on the upper side Hu is in communication with the inside of the shell body 232.

[0043] Furthermore, the lower side Hd of the outer harness insertion tube 231 is provided with an opening 236, which is formed by opening a portion of the lower side Hd of the inner side Db of the oval-shaped cylindrical body when viewed from the bottom. In addition, the end of the lower side Hd of the outer harness insertion tube 231 is provided with a wire holding portion 28, which will be described later.

[0044] The shell body 232 is positioned at the upper end Hu of the harness insertion tube exterior 231 and is slightly larger than the retaining body 222 positioned inside, with an open rear end Db, forming a roughly rectangular parallelepiped shape. Furthermore, in the shell body 232, which is formed in a roughly rectangular parallelepiped shape with the rear side Db open, the harness side terminal 21 is provided as a fitting opening 235 that is exposed on the rear side Db. In addition, a cover portion 233 is provided on the upper side Hu of the shell body 232, and a bolt hole 237 is provided near the center in the height direction H through which a fixing bolt 30 is inserted in the depth direction D.

[0045] The cover portion 233 is shaped like a truncated triangular pyramid in front view, protruding upward Hu from the shell body 232, and is formed to surround the fixing projection 144 and fixing bolt 15 that secure the male housing 14 of the equipment-side connector 10 to the mounting base 70 provided on the equipment housing 60.

[0046] Furthermore, the housing shell 23, which encloses the internal housing 22, is attached to a metal mounting base 70 by screwing in fixing bolts 30 (described later), and is electrically and physically connected, and is made of metal to provide electromagnetic shielding. The housing shell 23 configured in this way is formed by assembling divided shells, which are created by dividing the shell body 232 in the height direction H.

[0047] The housing seal 24 is a ring-shaped structure with a rectangular shape in plan view that matches the rear view shape of the inner wall 222b of the retaining body 222, and is made of rubber. The housing seal 24 is fitted onto the inner wall 222b of the inner housing 22 and is a sealing material that seals the space between the male housing 14 of the equipment-side connector 10 and the inner housing 22 of the harness-side connector 20 when the equipment-side connector 10 and the harness-side connector 20 are assembled.

[0048] The housing seal cover 25 is attached to the inner wall 222b of the inner housing 22 from the rear side Db in the depth direction D, and fixes the housing seal 24 which is placed on the holding part body 222 of the inner housing 22.

[0049] The wire seal 26 has through holes 261 through which two high-voltage wires 201 are inserted, and is a sealing member that seals the space between the high-voltage wires 201 inserted into the harness insertion cylinder portion 221 and the inner surface of the harness insertion cylinder portion 221. For this reason, the wire seal 26 is formed in an oval shape so that it can be placed inside the harness insertion cylinder portion 221.

[0050] The shell seal 27 is a sealing member that fits onto the harness insertion tube portion 221 of the internal housing 22 and seals the space between the harness insertion tube portion 221 and the outside of the harness insertion tube 231. The shell seal 27 is formed in an oval shape so that it can fit onto the harness insertion tube portion 221.

[0051] The wire holding portion 28, located at the lower end Hd of the outer harness insertion tube 231, holds the high-voltage wire 201 inserted through the harness insertion tube portion 221 to the outer harness insertion tube 231, and has a wire insertion hole 281 through which the high-voltage wire 201 is inserted.

[0052] Two wire insertion holes 281 are provided at a predetermined distance in the width direction W, corresponding to the two high-voltage wires 201 that make up the wire harness 200, and the wire insertion holes 281 are formed to have the same or slightly smaller diameter as the outer diameter of the high-voltage wires 201 through which they are inserted.

[0053] Furthermore, the wire holding portion 28 has a wire insertion hole 281 on the lower side Hd of the harness insertion tube outer 231 for holding the inserted high-voltage wire 201, and on the lower side Hd of the harness insertion tube outer 231, there is a fixed-side holding portion 282 which is integrally formed with the harness insertion tube outer 231 and a mounting holding portion 283 which is attached to the fixed-side holding portion 282, and a fixing bolt 284 for fixing the mounting holding portion 283 which is assembled to the fixed-side holding portion 282. The mounting and holding portion 283 can be fixed to the fixed-side holding portion 282 by assembling it to the fixed-side holding portion 282 of the harness insertion tube exterior 231 and screwing in the fixing bolt 284.

[0054] The harness-side connector 20, which is composed of these elements, is fitted into the equipment-side connector 10, which will be described later, and the fixing bolt 30 that secures the connection is a metal bolt in which a bolt head 32 is provided at the end of a screw shaft portion 31 that is screwed into a screw hole 74 provided in a fixing projection 73 of the mounting base 70. Furthermore, the screw shaft portion 31 is formed to be shorter than the length D in the depth direction of the shell body 232 in the housing shell 23 of the harness-side connector 20.

[0055] Next, as shown in Figures 1 to 3, we will describe the equipment-side connector 10 that is attached to a mounting base 70 provided on an equipment housing 60 in which electrical equipment is placed. The mounting base 70 is attached to the equipment housing 60, which is shown by the dashed line, and is a base for fixing the male housing 14 and the harness-side connector 20, which will be described later.

[0056] The mounting base 70 is a vertically elongated rectangle, longer in the height direction H than in the width direction W, with a through hole 71 penetrating in the depth direction D at the center when viewed from the front, and has a predetermined thickness in the depth direction D. Furthermore, the main front surface of the mounting base 70 is designated as the fixing main surface 72 for fixing the harness-side connector 20 to be mounted. Below the through hole 71 on the fixing main surface 72, on side Hd, there is a cylindrical fixing projection 73 that protrudes toward the front side Df. At the top of the fixing projection 73, there is a screw hole 74 into which a fixing bolt 30 for bolting the harness-side connector 20 is screwed.

[0057] On the main fixing surface 72 of Hu above the through hole 71, a screw hole 75 is provided in the center of the width direction W for fixing the male housing 14 (described later) with fixing bolts 15. The mounting base 70, configured in this way, is made of metal so that it can be electrically connected when the harness-side connector 20 (described later) is attached, and so that it can perform an electromagnetic shielding function.

[0058] Furthermore, the screw holes 75 into which the fixing bolts 15 that screw the male housing 14 are screwed are located opposite each other in the mounting base 70, across the through hole 71 into which the equipment-side terminals 11 are mounted, from the screw holes 74 provided in the fixing projection 73 into which the harness-side connector 20 is screwed to the mounting base 70.

[0059] Furthermore, the screw holes 75 into which the fixing bolts 15 for screwing and securing the male housing 14 are screwed, the through holes 71 for mounting the equipment-side terminals 11, and the screw holes 74 provided in the fixing protrusions 73 for screwing the harness-side connector 20 to the mounting base 70 are located in the center of the width direction W of the mounting base 70 and are arranged in a straight line in this order along the height direction H, separated from each other by predetermined intervals. The mounting base 70 configured in this way is attached to the equipment housing 60, which houses the electrical equipment, by an appropriate method.

[0060] As shown in Figure 5, the equipment-side connector 10, which is attached to the mounting base 70 provided on the equipment housing 60, comprises an equipment-side terminal 11, a regulating ring 12, an equipment-side seal 13, a male housing 14, and a fixing bolt 15. The equipment-side terminal 11 is connected to an electrical circuit that leads to an electrical device located inside the equipment housing 60, and is also connected to a harness-side terminal 21 located inside the harness-side connector 20. There are two of these terminals spaced apart at a predetermined distance in the width direction W.

[0061] Of the two device-side terminals 11, the device-side terminal 11 on one side in the width direction W, the first width direction Wo, is designated as the first device-side terminal 11a, and the device-side terminal 11 on the other side in the width direction W, the second width direction Ws, is designated as the other device-side terminal 11b. The device-side terminals 11 (11a, 11b) are made of metal plate material, and the terminal connection parts 111 (111a, 111b), connecting parts 112 (112a, 112b), and circuit connection parts 113 (113a, 113b) are arranged in this order from the front side Df to the back side Db in the depth direction D.

[0062] The terminal connection section 111 is the part that connects to the harness-side terminal 21 by connecting the harness-side connector 20 and the equipment-side connector 10. The connecting portion 112 is the part that connects the terminal connection portion 111 and the circuit connection portion 113, and the circuit connection portion 113 is the part that is connected to an electrical circuit (not shown) that is connected to an electrical device located inside the equipment housing 60.

[0063] The terminal connection portion 111 and the connecting portion 112 are formed continuously in the depth direction D, and the main surface of the plate material is formed to conform to the planes in the height direction H and the depth direction D. The terminal connection portion 111, which is connected to the harness-side terminal 21, is located inside the hood portion 142 of the male-type housing 14, which will be described later. The connecting portion 112, which is continuous with the terminal connection portion 111, penetrates the main body portion 141 and the insertion cylinder portion 143 of the male-type housing 14, which will be described later, and is formed to protrude from the insertion cylinder portion 143 toward the rear side Db. The portion of the connecting portion 112 that protrudes from the insertion cylinder portion 143 toward the rear side Db is called the protruding connecting portion 114.

[0064] The circuit connection portion 113 is bent perpendicular to the connecting portion 112 and is formed to conform to the planes in the width direction W and the height direction H. Furthermore, the one-side circuit connection portion 113a of the one-side equipment terminal 11a and the other-side circuit connection portion 113b of the other-side equipment terminal 11b are formed by bending the connecting portion 112 (112a, 112b) in different directions in the width direction W.

[0065] Specifically, the one-side circuit connection portion 113a of the one-side equipment terminal 11a in the first width direction Wo is formed by bending it perpendicular to the one-side connecting portion 112a toward the first width direction Wo, and the other-side circuit connection portion 113b of the other-side equipment terminal 11b in the second width direction Ws is formed by bending it perpendicular to the other-side connecting portion 112b toward the second width direction Ws. In other words, the one-side circuit connection portion 113a and the other-side circuit connection portion 113b are formed by bending them in directions that move them apart from each other in the width direction W.

[0066] As shown in Figure 8, the tips of the circuit connection portions 113, which are bent to be spaced apart from each other, are formed to protrude outward in the width direction W from the insertion cylinder portion 143 of the male housing 14, which will be described later, when viewed from the depth direction D.

[0067] Furthermore, as shown in Figure 10, the one-side circuit connection portion 113a of the one-side equipment terminal 11a and the other-side circuit connection portion 113b of the other-side equipment terminal 11b are located at different positions in the depth direction D.

[0068] More specifically, the one-sided protruding connecting portion 114a of the one-sided equipment-side terminal 11a is formed to be longer toward the inner side Db than the other-sided protruding connecting portion 114b of the other-sided equipment-side terminal 11b. The circuit connection portion 113, formed by bending the tip of the rear side Db of the connecting portion 112 (114), has a one-sided circuit connection portion 113a, which is longer toward the rear side Db than the other-side circuit connection portion 113b, which is provided at the tip of the rear side Db of the one-side protruding connecting portion 114a, positioned at the rear side Db.

[0069] As shown in Figure 10(a), the distance L in the depth direction D between the other side circuit connection portion 113b of the front side Df and the one side circuit connection portion 113a of the rear side Db, or more specifically, the distance L in the depth direction D between the rear side Db surface of the other side circuit connection portion 113b of the front side Df and the front side Df surface of the one side circuit connection portion 113a of the rear side Db, is formed to be wider than the thickness of the mounting base 70 described above, that is, the length La in the depth direction D of the mounting base 70.

[0070] The regulating ring 12 regulates the position in the depth direction D of the equipment-side seal 13, which is attached to the insertion tube portion 143 of the male housing 14 (described later), and is formed in a cylindrical shape that fits onto the insertion tube portion 143. The device-side seal 13 is a sealing member that is attached to the insertion tube portion 143 of the male housing 14 (described later) and seals the space between the insertion tube portion 143 of the male housing 14 and the mounting base 70. It is made of ring-shaped rubber.

[0071] The male housing 14 is for holding the equipment-side terminal 11 on the mounting base 70, and comprises a main body portion 141 for holding the equipment-side terminal 11, a hood portion 142 that surrounds the equipment-side terminal 11 held by the main body portion 141, a cylindrical insertion tube portion 143 that is inserted into the through hole 71 of the mounting base 70, and a fixing projection portion 144 for fixing the male housing 14 to the mounting base 70 with fixing bolts 15.

[0072] The main body portion 141 is configured to hold in an insulated state a portion of the connecting portion 112 of the equipment-side terminals 11, which are arranged at predetermined intervals in the width direction W. The hood portion 142 has an opening at the front side Df and is formed as a peripheral wall that protrudes toward the front side Df.

[0073] The insertion tube portion 143 is positioned at the rear Db of the main body portion 141 and, together with the main body portion 141, is configured to insert and hold a portion of the connecting portion 112 of the equipment-side terminal 11. Furthermore, the insertion tube portion 143 is formed in a disc shape with a diameter slightly smaller than the through hole 71 of the mounting base 70 so that it can be inserted into the through hole 71.

[0074] The fixing projection 144 protrudes from the center in the width direction W to the upper side Hu of the hood portion 142 and has a mounting hole for attaching a fixing bolt 15 that screws into the screw hole 75 of the mounting base 70 to fix the male housing 14.

[0075] The device-side connector 10, with each element configured in this way, is assembled by attaching the device-side terminals 11 to the main body portion 141 of the male housing 14, and by fitting the device-side seal 13 and regulating ring 12 onto the insertion cylinder portion 143. Specifically, the terminal connection part 111 is located inside the hood part 142, the connecting part 112 is inserted through the main body part 141 and the insertion cylinder part 143, and the equipment-side terminal 11 is attached to the male housing 14 such that the connecting part 112 protrudes to the rear side Db beyond the insertion cylinder part 143.

[0076] At this time, the device-side terminal 11 is attached to the male housing 14 such that the circuit connection portion 113a of one side terminal connection portion 111a faces the first width direction Wo, and the circuit connection portion 113b of the other side terminal connection portion 111b faces the second width direction Ws, that is, the circuit connection portions 113 of the terminal connection portion 111 are spaced apart from each other in the width direction W.

[0077] Furthermore, as shown in Figure 8, the tip of the circuit connection portion 113 of the device-side terminal 11 attached to the male housing 14 will protrude outward in the width direction W from the insertion cylinder portion 143 when viewed from the depth direction D.

[0078] Then, the insertion tube portion 143 of the male housing 14, to which the equipment-side terminal 11, regulating ring 12, and equipment-side seal 13 are assembled, is inserted into the through hole 71 of the mounting base 70, and the fixing bolt 15 attached to the fixing projection 144 is screwed into the screw hole 75 to fix the mounting base 70 and the male housing 14, thereby completing the assembly of the equipment-side connector 10.

[0079] However, the tips of the circuit connection portions 113 of the two device-side terminals 11 protrude outward in the width direction W from the insertion cylinder portion 143. In other words, as shown in Figure 10(b), the length Wx between the tips of the circuit connection portions 113 is longer than the diameter Wy of the through hole 71. Therefore, the device-side connector 10 positioned on the front side Df of the through hole 71 cannot be attached as is, as shown in Figure 10(a), with the circuit connection portions 113 positioned on the back side Db of the through hole 71.

[0080] Therefore, the equipment-side connector 10 positioned on the front side Df of the through-hole 71 is shifted in the second width direction Ws, and as shown in Figure 11(a), the one-side circuit connection part 113a, positioned on the back side Db of the other-side circuit connection part 113b, is inserted into the through-hole 71. At this time, the other-side circuit connection part 113b, whose spacing L is longer than the thickness La of the mounting base 70, is positioned on the front side Df of the mounting base 70.

[0081] In this state, as shown in Figure 11(b), the equipment-side connector 10 is moved in the first width direction Wo to such an extent that the one-side connecting portion 112a abuts against the first width direction Wo of the through hole 71. Then, as shown in Figure 11(c), the front side Df of the equipment-side connector 10 is tilted in the second width direction Ws so that the other side circuit connection portion 113b is inserted into the through hole 71. As a result, as shown in Figure 11(d), both the one side circuit connection portion 113a of the one side equipment-side terminal 11a and the other side circuit connection portion 113b of the other side equipment-side terminal 11b can pass through the through hole 71 and be positioned inside the equipment housing 60, which is the rear side Db of the mounting base 70.

[0082] Then, as shown in Figure 11(d), by returning the tilt of the equipment-side connector 10 to its original position and inserting the insertion cylinder portion 143 into the through hole 71, the insertion cylinder portion 143 can be inserted into the through hole 71, as shown in Figure 10(a).

[0083] Furthermore, the male housing 14 of the device-side connector 10 is securely and stably fixed to the mounting base 70 by the fixing bolt 15 and fixing projection 144, as the insertion cylinder portion 143 is inserted into the through hole 71 and the housing is fixed to the mounting base 70.

[0084] The harness-side connector 20 is fitted to the equipment-side connector 10, which is mounted on the mounting base 70 assembled in this manner, and then secured with the aforementioned fixing bolt 30 to complete the connection, thereby completing the connector connection structure 1 that can establish an electrically and physically stable connection state.

[0085] More specifically, the harness-side connector 20 is positioned relative to the equipment-side connector 10 so as to connect the equipment-side terminal 11, which is held inside the male housing 14 of the equipment-side connector 10 attached to the mounting base 70 of the equipment housing 60, with the harness-side terminal 21, which is held inside the shell body 232 of the harness-side connector 20.

[0086] Then, the harness-side connector 20 is moved to the rear side Db relative to the equipment-side connector 10 which is attached to the mounting base 70 provided on the equipment housing 60, and the equipment-side connector 10 and the harness-side connector 20 are assembled.

[0087] At this time, the hood portion 142 of the male housing 14 of the equipment-side connector 10 is inserted between the outer wall 222a and the inner wall 222b that constitute the retaining portion body 222, which is located inside the shell body 232, and the equipment-side terminal 11 and the harness-side terminal 21 come into contact with each other.

[0088] In this manner, the bolt holes 237 of the harness-side connector 20, which is assembled to the equipment-side connector 10, face the threaded holes 74 of the fixing projection 73 provided on the mounting base 70 in the depth direction D. Then, the fixing bolt 30 is inserted into the bolt hole 237 from the front side Df of the harness-side connector 20, and the threaded shaft portion 31 of the fixing bolt 30 is screwed into the threaded holes 74 provided on the fixing projection 73 of the mounting base 70. This completes the screw-fixing of the assembled equipment-side connector 10 and harness-side connector 20 with the fixing bolt 30, thus completing the connection between the equipment-side connector 10 and the harness-side connector 20, and forming the connector connection structure 1.

[0089] As described above, the equipment-side connector 10, which mates with the harness-side connector 20 and connects the terminals (11, 21) provided on each to form the connector connection structure 1, is equipped with two equipment-side terminals 11 and a male-type housing 14 that has a portion of the equipment-side terminals 11 arranged inside and is fixed to the equipment housing 60. The male-type housing 14 is provided with an insertion cylinder portion 143 that is inserted through a through hole 71 provided in the equipment housing 60 and attached.

[0090] The device-side terminal 11 includes a terminal connection portion 111 that connects to the harness-side terminal 21, a circuit connection portion 113 that is located inside the device housing 60 and connected to an electrical circuit that is connected to an electrical device provided inside the device housing 60, and a connecting portion 112 that connects the terminal connection portion 111 and the circuit connection portion 113. The connecting portion 112 extends along the depth direction D through which the insertion cylinder portion 143 is inserted into the through hole 71.

[0091] The circuit connection portion 113 is positioned on the outside of the width direction W where the circuit connection portions 113a and 113b are spaced apart from each other, and along the width direction W that intersects with respect to the connecting portion 112. It is also formed with a length such that, when viewed from the depth direction D, its tip protrudes beyond the outer shape of the insertion cylinder portion 143. Furthermore, the circuit connection portion 113a of one equipment-side terminal 11a is positioned at a different position in the depth direction D relative to the other circuit connection portion 113b of the other equipment-side terminal 11b. Therefore, the equipment-side connector 10 constituting the connector connection structure 1 can efficiently connect the electrical circuit connected to the electrical equipment located inside the equipment housing 60 to the equipment-side terminal 11 without increasing its size.

[0092] More specifically, in the equipment-side connector 10 that mates with the harness-side connector 20 and connects the terminals provided on each, two equipment-side terminals 11, at least partially located inside a male housing 14 fixed to the equipment housing 60, are provided with a terminal connection portion 111 that connects to the harness-side terminal 21 of the harness-side connector 20, a circuit connection portion 113 located inside the equipment housing 60 and connected to an electrical circuit connected to an electrical device located inside the equipment housing 60, and a connecting portion 112 that connects the terminal connection portion 111 and the circuit connection portion 113. The connecting portion 112 extends along the depth direction D through which the insertion cylinder portion 143 is inserted into the through hole 71, and the circuit connection portion 113 is located outside the width direction W where the circuit connection portions 113a and 113b are spaced apart, and along the width direction W that intersects with respect to the connecting portion 112. Therefore, the circuit connection portions 113 of the two device-side terminals 11 can be positioned in the width direction W, which intersects the depth direction D, and electrical circuits connected to electrical equipment provided inside the device housing 60 can be efficiently connected to the circuit connection portions 113.

[0093] Furthermore, although the circuit connection portion 113 is formed to a length such that its tip protrudes beyond the outer shape of the insertion cylinder portion 143 when viewed from the depth direction D, the circuit connection portion 113a of one side equipment-side terminal 11a is located at a different position in the depth direction D. Therefore, as shown in Figure 11, the circuit connection portions 113a and 113b, which are located at different positions in the depth direction D, can be inserted one by one into the through hole 71. Thus, the diameter of the through hole 71 only needs to be such that the circuit connection portion 113a of one side equipment-side terminal 11a and the other side connecting portion 112b of the other side equipment-side terminal 11b can pass through, and the diameter of the through hole 71 can be reduced compared to the case where the circuit connection portions 113a and 113b can pass through simultaneously. Therefore, the insertion cylinder portion 143 that fits into the through hole 71 can also be reduced in diameter, and the size of the equipment-side connector 10 can be suppressed.

[0094] Furthermore, within the device housing 60, the protruding length of one of the protruding connecting parts 114a, which are the parts that protrude from the insertion cylinder portion 143 of the connecting part 112 at multiple device-side terminals 11, is set to be longer than the protruding length of the other protruding connecting part 114b.

[0095] Therefore, by providing a circuit connection portion 113 at the tip of the protruding connecting portion 114, the circuit connection portions 113a and 113b can be positioned at different locations in the depth direction D. Furthermore, by adjusting the length of the protruding connecting portion 114, the circuit connection portion 113 can be positioned at a desired location in the depth direction D.

[0096] Furthermore, since the circuit connection portions 113 of the multiple device-side terminals 11 extend along the planes in the width direction W and height direction H that are perpendicular to the depth direction D, at different positions in the depth direction D, the circuit connection portions 113a and 113b, which are located at different positions in the depth direction D, can be arranged in parallel. Therefore, electrical circuits can be connected to the circuit connection portions 113 from the same direction.

[0097] Furthermore, since the device-side terminal 11 is made of a metal plate and the circuit connection portion 113 is formed by bending it in the thickness direction relative to the connecting portion 112, the circuit connection portion 113 can be easily positioned on the outside of the width direction W where the circuit connection portions 113a and 113b are separated, and along the width direction W that intersects with the connecting portion 112.

[0098] Furthermore, the through-hole 71 is provided in a metal mounting base 70 that is attached to the equipment housing 60, and the spacing L in the depth direction D between the circuit connection portions 113a and 113b of the multiple equipment-side terminals 11 is set to be wider than the thickness La of the mounting base 70. Therefore, when the one-side circuit connection portion 113a of one-side equipment-side terminal 11a is passed through the through-hole 71, the other-side circuit connection portion 113b of the other-side equipment-side terminal 11b is not inserted into the through-hole 71 of the mounting base 70. As shown in Figure 11, each circuit connection portion 113 can be inserted through the through-hole 71 without interfering with the mounting base 70, and the insertion cylinder portion 143 can be inserted through the through-hole 71 and attached to the mounting base 70.

If it has three or more device-side terminals 11, all circuit connection parts 113 may be located at different positions in the depth direction D, or at least one circuit connection part 113 may be located at a different position in the depth direction D relative to the other circuit connection parts 113.

[0101] Furthermore, in the equipment-side terminal 11, the circuit connection portion 113 was formed by bending the connecting portion 112 perpendicular to the plate thickness direction. However, the circuit connection portion 113 may also be formed by bending the connecting portion 112 at an acute or obtuse angle.
