Description

The present disclosure relates to a high voltage connector.

High-voltage connectors used in hybrid vehicles and electric vehicles have a tubular shape that is externally fitted to the flat plate-shaped mating terminal to enable stable connection to the flat-plate mating terminal configured by a bus bar or the like. High voltage connectors with terminals are widely used. For example, Patent Document 1 discloses a high-voltage connector having a cylindrical female terminal connected to a flat plate-shaped device-side terminal which is a mating terminal.

Japanese Unexamined Patent Publication No. 2014-86152

By the way, since the device to which the high voltage connector is connected is relatively large, the position of the mating terminal varies due to the tolerance on the device side, and it becomes difficult to connect the high voltage connector to the mating terminal. There is. Therefore, in the high voltage connector described in Patent Document 1, a structure is adopted in which the female terminal and the electric wire are connected by an elastic conductor and the female terminal is displaceably held with respect to the connector housing. ing. As a result, even if the position of the mating terminal varies, the position of the female terminal can be displaced by the deformation of the elastic conductor, and the mating terminal and the female terminal can be surely brought into contact with each other.

However, in a high voltage connector having a cylindrical female terminal as in Patent Document 1, it is desired to simplify the shape and realize low cost. It is also required to reduce the storage space of terminals to meet the demand for miniaturization. Furthermore, it is also technical to simplify the structure in which the cylindrical female terminal is crimped to the elastic conductor composed of the braided body of the conductive wire to reduce the number of parts and facilitate the manufacturing. There is great significance. Further, it has been required to suppress the electric resistance that increases at the connection portion between the female terminal and the elastic conductor to improve the conductivity and suppress the heat generation.

Therefore, we will disclose a high-voltage connector with a new structure that can improve conductivity and reduce heat generation while stably realizing connection with the mating terminal by a simple structure with a small number of parts.

The high-voltage connector of the present disclosure is integrally provided with a terminal fitting having a flat plate-shaped terminal main body portion that is overlapped with a flat plate-shaped mating terminal in the plate thickness direction, and the terminal main body portion, and at least a part thereof. Includes an elastic contact portion that is inclined toward the overlapping side with the mating terminal.

According to the present disclosure, a simple structure with a small number of parts enables stable connection to the mating terminal, while improving conductivity and reducing heat generation.

<Explanation of Embodiments of the present disclosure>
First, embodiments of the present disclosure will be listed and described.
The high voltage connector of the present disclosure is
(1) A terminal fitting having a flat plate-shaped terminal body that is overlapped with a flat plate-shaped mating terminal in the plate thickness direction, and a terminal fitting that is integrally provided on the terminal body and at least a part thereof is connected to the mating terminal. A high-voltage connector that includes an elastic contact that tilts toward the stacking side.

According to the high-voltage connector described in the present disclosure, the terminal main body constituting the terminal fitting has a flat plate shape, so that the conventional tubular female used for connection to the flat plate-shaped mating terminal is used. Since the shape is simpler than that of the mold terminal, the cost can be reduced. In addition, the storage space in which the terminal body is housed can be reduced, and the high-voltage connector can be miniaturized.

If the terminal main body connected to the flat plate-shaped mating terminal is made flat, poor contact of the terminal main body with respect to the mating terminal is likely to occur. However, in the high voltage connector of the present disclosure, the elasticity provided in the terminal main body is provided. Stable contact with the mating terminal is maintained at the contact portion. That is, the elastic contact portion has a portion that inclines in the plate thickness direction of the terminal body portion in the direction of projecting toward the mating terminal side, and the inclined portion can be elastically deformed so that the inclination angle changes in the plate thickness direction. It is said that. Therefore, when the elastic contact portion is pressed against the mating terminal, the variation in the position of the mating terminal is absorbed by the elastic deformation of the elastic contact portion, and the contact state between the mating terminal and the elastic contact portion is stably realized. ..

Since the elastic contact portion is integrally provided on the terminal fitting, the above-mentioned avoidance of contact failure is realized by a simple structure with a small number of parts. Moreover, since the elastic contact portion has an integral structure, it is difficult for a local increase in electrical resistance to occur at the connection portion as in the case of connecting two separate parts, and excellent conductivity is realized and when energized. It is also possible to suppress the heat generation of.

(2) It is preferable that the elastic contact portion is provided on the terminal body portion by cutting and raising. Since the elastic contact portion is provided by cutting out a part of the terminal main body portion, the elastic contact portion integrated with the terminal main body portion can be easily provided. Further, it is easy to provide an inclined portion in the elastic contact portion so that the elastic contact portion projects toward the mating terminal side at least in part.

(3) In the above (2), the terminal main body portion has a frame-shaped portion constituting the outer peripheral end portion and the elastic contact portion provided on the inner peripheral side of the frame-shaped portion via a slit. The elastic contact portion is integrally connected to the frame-shaped portion at the base end, is inclined and raised like a cantilever on the overlapping side with the mating terminal, and can be elastically deformed in the plate thickness direction. It is preferably leaf spring-like. Thereby, the elastic contact portion provided by cutting and raising can be provided with good yield and durability.

(4) In the above (2) or (3), the elastic contact portion is provided with a first inclined portion that is inclined toward the tip of the terminal main body portion so as to be overlapped with the mating terminal. A second inclined portion is provided on the tip side of the elastic contact portion with respect to the first inclined portion so as to be inclined toward the tip of the terminal main body portion on the side opposite to the overlapping side with the mating terminal. It is preferable that it is.

According to this, the elastic contact portion is held in a contact state with respect to the mating terminal based on the elasticity of the first inclined portion. Further, by providing the second inclined portion on the tip side of the first inclined portion, the tip of the mating terminal hits the second inclined portion when the mating terminal is inserted from the tip side. As a result, the mating terminal can be guided along the second inclined portion without being caught, and the mating terminal can be inserted to an appropriate position.

(5) In the above (1), the elastic contact portion may be provided by folding back at the tip of the terminal main body portion. By providing the elastic contact portion by folding the terminal body portion at the tip, it is possible to easily provide the elastic contact portion integrated with the terminal body portion. Further, it is easy to provide an inclined portion in the elastic contact portion so that the elastic contact portion projects toward the mating terminal side at least in part. Further, since the tip end side of the terminal main body portion is folded back into a curved shape, the mating terminal is less likely to be caught by the tip end of the terminal main body portion when the mating terminal is inserted from the tip end side and superposed on the elastic contact portion.

(6) In the above (5), the terminal main body portion has a flat plate-shaped portion, a curved folded-back portion provided at the tip of the flat plate-shaped portion, and the elastic contact extending from the folded-back portion toward the base end side. The elastic contact portion has a portion, and is integrally connected to the folded portion at the base end, is inclined like a cantilever on the overlapping side with the mating terminal, and can be elastically deformed in the plate thickness direction. It is preferably leaf spring-like. Thereby, the elastic contact portion provided by the folding can be provided with good manufacturability.

(7) In the above (5) or (6), the third is inclined toward the base end of the terminal main body portion, which is the side opposite to the folded side of the elastic contact portion, toward the overlapping side with the mating terminal. An inclined portion is provided in the elastic contact portion, and is superposed on the mating terminal toward the proximal end of the terminal main body portion on the proximal end side of the elastic contact portion with respect to the third inclined portion. It is preferable to have a fourth inclined portion that inclines to the side opposite to the side.

According to this, the portion of the elastic contact portion that protrudes toward the overlapping side with the mating terminal is formed by the third inclined portion, and the elastic contact portion is held in the contact state with respect to the mating terminal. Further, when the mating terminal is inserted from the tip side and superposed on the elastic contact portion by the third inclined portion, the tip of the mating terminal is in contact with the third inclined portion and guided, so that the mating terminal is guided. It is smoothly inserted to the proper position without getting caught. Further, since the fourth inclined portion is inclined toward the base end side so as to approach the terminal main body portion, the fourth inclined portion hits the opposite terminal main body portion when the elastic contact portion is elastically deformed. The contact limits the amount of deformation of the folded portion, in other words, the change in the angle of the third inclined portion. Therefore, excessive deformation of the folded portion is prevented, and damage such as plastic deformation of the folded portion is avoided. In addition, in the contact state between the elastic contact portion and the mating terminal, the base end of the elastic contact portion is arranged away from the mating terminal by the fourth inclined portion, and the mating terminal is damaged due to the contact of the base end edge of the elastic contact portion. Etc. are also prevented.

(8) The terminal fitting preferably includes a fixing portion fixed to a connector housing having a terminal insertion hole through which the terminal body portion is inserted. By fixing the terminal fitting to the connector housing, the runout of the terminal body portion is reduced, and the storage space for accommodating the terminal body portion can be reduced to reduce the size.

(9) In the above (8), the end portion of the electric wire is connected to the terminal fitting at the fixing portion, and a fixing member for collectively fixing the fixing portion, the connector housing, and the end portion of the electric wire is provided. It is preferable that the cable is used. Since the fixing position of the terminal fitting and the connector housing is substantially the same as the fixing position of the terminal fitting and the electric wire, for example, when the input from the electric wire side is transmitted to the connector housing via the terminal fitting, The moment acting on the terminal fitting is reduced by the input. Therefore, it becomes easy to prevent runout and misalignment of the terminal main body in the terminal fitting.

(10) In the above (8) or (9), the terminal fitting is housed in the connector housing so that the plate thickness direction of the terminal body portion is the vertical direction of the terminal insertion hole. Is preferable. The terminal fitting can be accommodated in the connector housing so that the vertical direction of the terminal insertion hole of the connector housing is the plate thickness direction of the terminal main end. Therefore, it is possible to advantageously achieve a lower profile of the connector housing itself as compared with the case where the vertical direction of the terminal insertion hole of the connector housing is the plate width direction of the terminal main body portion.

(11) In the above (10), the terminal insertion hole has a flat rectangular shape, is located in the central portion in the vertical direction, and has a pair of partition plate portions protruding inward from both side surfaces. The vacant space located above the pair of partition plates is used as the mating terminal insertion portion, and the vacant space located below the pair of partition plates is used as the terminal main body accommodating portion, and the pair of partition plates are opposed to each other. It is preferable that the pair of elastic contact portions are arranged so as to be contactable with the mating terminal between the surfaces. With a simple structure in which a pair of partition plates protruding inward from both side surfaces of the terminal insertion hole is provided, the terminal main body can be accommodated and held in a state where it can be connected to the mating terminal in a small space.

(12) In the above (11), the terminal body portion of the terminal fitting extends along the axial direction of the terminal body portion accommodating portion, and the fixing portion of the terminal fitting extends from the base end of the terminal body portion. It has a pressing rib that extends downward in the vertical direction and is provided on the lower surface of the partition plate portion and projects toward the lower inner surface of the terminal main body portion accommodating portion, and the pressing rib is the terminal main body portion. It is preferable that the tip portion of the is pressed toward the lower inner surface. The terminal fitting has an L-shape including a terminal main body portion and a fixing portion extending downward from the base end of the terminal main body portion. When the fixing part is fixed to the connector housing, the tip of the terminal body provided on the opposite side of the fixing part of the L-shaped terminal fitting may be lifted upward by the fixing force of the connector housing of the fixing part. be. However, the tip of the terminal body can be pressed toward the lower inner surface by the pressing rib provided on the upper inner surface of the terminal insertion hole. This prevents the terminal body from rising and holds the L-shaped terminal fitting in a stable position with respect to the connector housing by the cooperation of the fixing part and the pressing rib. can do.

(13) In the above (8) or the above (9), a crushing rib projecting from one of the facing inner surfaces of the terminal insertion hole toward the other is provided, and the terminal main body portion is provided with the crushing rib and the other. It is preferable that the position is sandwiched between the facing inner surfaces.

According to this, the crushing ribs protruding from the opposite inner surface of the terminal insertion hole are appropriately crushed by the terminal main body portion, so that the dimensional tolerance of the terminal insertion hole is allowed. Since the crushing rib is provided so as to project only from one of the opposite inner surfaces of the terminal insertion hole toward the other, the terminal main body is stably pressed against the other opposite inner surface of the terminal insertion hole by the crushing rib. Positioned. By sandwiching and holding the terminal main body between the crushing rib and the other facing inner surface of the terminal insertion hole, runout of the terminal main body is suppressed, and for example, the storage space of the terminal main body is reduced. be able to.

(14) It is preferable that the terminal fitting is connected to the end of the electric wire without an elastically deformable member. Since the terminal body is provided with an elastic contact portion, the number of parts can be increased even if an elastically deformable member such as a braided body as in a conventional structure does not intervene between the terminal fitting and the end of the electric wire. This is because a stable contact state between the terminal body and the mating terminal can be realized by a simple structure with few.

(15) It is preferable that the terminal body is surrounded by a shield member. This is because it is possible to further prevent noise leakage while realizing miniaturization and stabilizing the connection with the connector on the other side in the high voltage connector.

As a result, the elastic contact portion 38 of the terminal main body portion 34 is pushed by the mating terminal 76 and elastically deformed so that the inclination angle with respect to the frame-shaped portion 36 becomes smaller. The degree of tilting of the elastic contact portion 38 with respect to the frame-shaped portion 36 changes according to the relative positions of the terminal main body portion 34 and the mating terminal 76 in the left-right direction. Therefore, even if an error occurs in the relative positions of the terminal body 34 and the mating terminal 76 in the left-right direction, the elastic contact portion 38 of the terminal body 34 is elastically pressed against the mating terminal 76, and the terminal body The contact state between the portion 34 and the mating terminal 76 is stably realized. In FIG. 11, the elastic contact portion 38 in the single state of the terminal main body portion 34 that is not in contact with the mating terminal 76 is shown by the alternate long and short dash line.

As described above, since the terminal main body 34 is provided with the elastic contact portion 38 that is allowed to be elastically deformed and displaced, the contact state between the terminal main body 34 and the mating terminal 76 is easy with a small number of parts. It is stably realized by the structure. Moreover, the elastic contact portion 38, which is allowed to be elastically deformed and displaced, is formed in an integral structure with the frame-shaped portion 36 by cutting and raising, and there are two parts between the elastic contact portion 38 and the frame-shaped portion 36. The increase in resistance caused by the connection cannot occur. Therefore, excellent conductive performance is realized, and heat generation due to energization can be reduced.

Further, by providing the elastic contact portion 38 in the terminal main body portion 34, the terminal main body portion 34 connected to the mating terminal 76 which is made into a flat plate shape is not a cylindrical shape like a conventional female terminal but a flat plate shape. Has been done. Since the structure of the terminal body portion 34 is simplified in this way, the cost of the terminal fitting 16 can be reduced, the manufacturing of the terminal fitting 16 can be facilitated, and the storage space of the terminal fitting 16 can be narrowed, so that the high voltage connector 10 can be downsized. And so on.

By providing the first inclined portion 42, the top portion 40 of the elastic contact portion 38 protrudes from the frame-shaped portion 36 toward the mating terminal 76 in the plate thickness direction, and the mating terminal 76 with respect to the terminal main body portion 34. Contact is made at the elastic contact portion 38, and the connection between the mating terminal 76 and the terminal main body portion 34 is stably realized. Further, since the second inclined portion 44 is provided in the front portion of the elastic contact portion 38, when the mating terminal 76 is inserted from the front to the rear of the terminal main body portion 34, the mating terminal 76 becomes the second. Guided along the surface of the second ramp 44. Therefore, the mating terminal 76 is hard to be caught by the elastic contact portion 38, the high voltage connector 10 and the mating side connector 74 are smoothly connected, and the mating terminal 76 is inserted to an appropriate connection position with respect to the terminal main body portion 34. To.

Since the elastic contact portion 38 of the terminal main body portion 34 is elastically contacted with the mating terminal 76 and conducted, an elastically deformable member such as a braid is interposed between the terminal fitting 16 and the electric wire 60. It is not necessary to allow the terminal fitting 16 to be displaced with respect to the electric wire 60. Therefore, the tolerance of the relative position between the terminal body 34 and the mating terminal 76 is allowed by the simple structure with a small number of parts, and the stable connection between the terminal body 34 and the mating terminal 76 is realized by the simple structure. ..

In the following description, the members and parts substantially the same as those in the first embodiment are designated by the same reference numerals in the drawings, and the description thereof will be omitted.

Compared to the terminal fitting 16 of the first embodiment, the terminal fitting 82 has a structure that does not include the electric wire connecting portion 50, and is composed of a terminal main body portion 34 and a fixing portion 48. The fixing portion 48 of the terminal fitting 82 is overlapped on the rear surface of the connector housing 14, and the plate-shaped connecting portion 66 of the crimp terminal 62 provided at the end of the electric wire 60 is overlapped on the rear surface of the fixing portion 48. .. Then, the bolt 56 as a fixing member is inserted into the bolt hole 52 of the terminal fitting 82 and the bolt hole 68 of the crimp terminal 62, and the bolt 56 is screwed to the nut portion 84 of the connector housing 14. As a result, the terminal fitting 82 and the crimp terminal 62 fixed to the electric wire 60 are collectively fixed to the connector housing 14 at substantially the same position. The fixing portion 48 of the terminal fitting 82 fixed to the connector housing 14 with the bolt 56 and the plate-shaped connecting portion 66 of the crimp terminal 62 are in contact with each other and overlapped with each other, and the terminal fitting 82 and the electric wire 60 are mutually conducted. ing. The crimp terminal 62 may be arranged so as to be located between the connector housing 14 and the fixing portion 48 of the terminal fitting 82, in other words, to be overlapped on the front surface of the fixing portion 48. The fixing member for collectively fixing the terminal fitting 82 and the crimp terminal 62 provided on the electric wire 60 to the connector housing 14 is not limited to the bolt 56, and may be made of, for example, a pin or an alloy for brazing. ..

According to the second embodiment, since the electric wire 60 is fixed to the connector housing 14 together with the terminal fitting 82, the input from the electric wire 60 side to the terminal fitting 82 side is immediately transmitted to the connector housing 14. It is difficult to receive it and transmit it to the terminal body 34 of the terminal fitting 82. Further, a moment based on the input from the electric wire 60 acts on the terminal metal fitting 82 as compared with the case where the fixing position of the terminal metal fitting 82 to the connector housing 14 and the fixing position of the electric wire 60 to the terminal metal fitting 82 are different. Since it is difficult to do so, runout and misalignment of the terminal fitting 82 are prevented.

<Embodiment 3>
FIG. 14 shows Embodiment 3 of the present disclosure. The high voltage connector 90 includes a pair of terminal fittings 92 and 92. Since the pair of terminal fittings 92 and 92 have a mutually plane-symmetrical shape, only one of the terminal fittings 92 will be described as in the first embodiment.

The terminal fitting 92 is made of a conductive metal material. As shown in FIGS. 15 and 16, the terminal fitting 92 includes a plate-shaped terminal body portion 94. A fixing portion 48 and a wire connecting portion 50 are integrally provided on the base end side (rear side) of the terminal main body portion 94. The terminal body portion 94 has a flat plate-shaped portion 96 extending forward from the fixing portion 48, and an elastic contact portion 98 extending forward at the tip of the flat plate-shaped portion 96. The width dimension of the flat plate-shaped portion 96 in the vertical direction (the Z direction in FIG. 15 and the direction opposite to Z) changes in two stages, and the tip side is narrower than the base end side. The terminal fitting 92 can be obtained, for example, by pressing a base plate made of a conductive metal.

The elastic contact portion 98 is provided with a curved folded portion 100 at the tip of the flat plate-shaped portion 96 which is the tip of the terminal main body portion 94, and the terminal main body portion 94 is folded back toward the proximal end side at the folded portion 100 and extends. It is formed by that. Therefore, the terminal body portion 94 has a double structure in which the elastic contact portion 98 and the flat plate-shaped portion 96 face each other apart from each other in the plate thickness direction at the tip portion. The elastic contact portion 98 faces the tip portion having a small vertical width dimension with respect to the flat plate-shaped portion 96, and does not reach the base end portion having a large vertical width dimension.

The base end of the elastic contact portion 98 is integrally connected to the folded-back portion 100, and the tip portion of the elastic contact portion 98 is a third inclined portion 102. The third inclined portion 102 is inclined toward the base end of the terminal main body portion 94 toward the outside in the left-right direction (the direction opposite to the Y direction in FIG. 15) on the overlapping side with the mating terminal 76 (see FIG. 16). is doing. That is, the elastic contact portion 98 is a leaf spring shape that is inclined like a cantilever on the overlapping side with the mating terminal 76 and can be elastically deformed in the plate thickness direction. Thereby, the elastic contact portion 98 provided by the folding can be provided with good manufacturability. The tip portion of the elastic contact portion 98 composed of the third inclined portion 102 has an increasing distance from the flat plate-shaped portion 96 toward the proximal end side as the tip portion thereof is separated from the folded-back portion 100 toward the proximal end side. It protrudes greatly to the outside in the left-right direction.

The base end portion of the elastic contact portion 98 is a fourth inclined portion 104. The fourth inclined portion 104 is inclined inward in the left-right direction (Y direction in FIG. 15) on the side opposite to the overlapping side with the mating terminal 76 toward the base end side of the terminal main body portion 94. The base end portion of the elastic contact portion 98 composed of the fourth inclined portion 104 approaches the flat plate-shaped portion 96 toward the base end side of the terminal main body portion 94, and has a flat plate shape with the fourth inclined portion 104. The distance between the facing portions 96 is the minimum at the base end of the fourth inclined portion 104. Therefore, the elastic contact portion 98 is composed of a continuous third inclined portion 102 and a fourth inclined portion 104, and is a boundary portion between the base end of the third inclined portion 102 and the tip end of the fourth inclined portion 104. In, the amount of protrusion to the outside in the left-right direction is the maximum. The length of the fourth inclined portion 104 is shorter than that of the third inclined portion 102, and the bending due to bending in the plate thickness direction is suppressed. In addition, in FIG. 16, the mating terminal 76 is virtually shown by a two-dot chain line. Similar to the first embodiment, the mating terminal 76 is inserted from the tip end side of the terminal body portion 94 while pushing the elastic contact portion 98 inward in the left-right direction, and is superposed on the elastic contact portion 98 in a contact state.

The distance between the fourth inclined portion 104 and the flat plate-shaped portion 96 in the left-right direction is set according to the angle change allowed for the third inclined portion 102 in the contact state between the elastic contact portion 98 and the mating terminal 76. That is, when the elastic contact portion 98 is pushed inward in the left-right direction by the mating terminal 76, the base end of the fourth inclined portion 104 hits the flat plate-shaped portion 96, so that the amount of displacement of the elastic contact portion 98 inward to the left and right. Is limited so that the angle change of the third inclined portion 102 is limited. The base end of the fourth inclined portion 104 may be separated from the flat plate-shaped portion 96 or in contact with the flat plate-shaped portion 96 in a state where the elastic contact portion 98 is not in contact with the mating terminal 76. May be good.

However, the fourth inclined portion 104 is not essential, and for example, the entire elastic contact portion may be composed of the third inclined portion 102. A portion substantially parallel to the flat plate-shaped portion 96 may be provided on the base end side of the third inclined portion 102 to increase the contact area of the elastic contact portion with the mating terminal 76.

According to the high-voltage connector 90 provided with the terminal fittings 92 and 92 having a structure according to the present embodiment, the contact state with the mating terminal 76 is maintained by the elastic contact portion 98 having a simple structure formed by folding. It can be obtained stably.

Further, since the folded portion 100 folded back in a curved shape is provided at the tip portion of the terminal main body portion 94, when the mating terminal 76 is inserted into the terminal main body portion 94 from the tip side, the mating terminal is inserted. The 76 is less likely to be caught by the tip of the terminal body 94, and is smoothly guided to the overlapping side with the elastic contact 98. Moreover, the tip portion of the elastic contact portion 98 continuous with the folded-back portion 100 is a third inclined portion 102, and the terminal main body portion 94 has a width dimension in the left-right direction toward the tip in the formed portion of the elastic contact portion 98. Is getting smaller. As a result, it is possible to stably realize the contact state with the mating terminal 76 while preventing the mating terminal 76 inserted from the tip side from being caught.

The elastic contact portion 98 is inclined toward the base end in the third inclined portion 102 toward the overlapping side with the mating terminal 76, and protrudes toward the mating terminal 76 side. Therefore, when the mating terminal 76 is inserted into and overlapped with the elastic contact portion 98 from the tip side, the elastic contact portion 98 protruding toward the mating terminal 76 side stably contacts the mating terminal 76.

Further, since the base end of the fourth inclined portion 104 hits the flat plate-shaped portion 96, the amount of displacement of the elastic contact portion 98 with the change in the inclined angle of the third inclined portion 102 to the flat plate-shaped portion 96 is limited. It has become so. Therefore, excessive deformation of the folded portion 100 is prevented, and plastic deformation of the folded portion 100 is prevented. As a result, for example, even if the connection and disconnection between the high voltage connector 90 and the mating connector (not shown) are repeated, the contact state between the elastic contact portion 98 of the terminal main body portion 94 and the mating terminal 76 is stable.

Further, the edge on the base end side of the elastic contact portion 98 is separated from the contact position with the mating terminal 76 in the overlapping direction with the mating terminal 76 by the fourth inclined portion 104. As a result, damage such as galling of the mating terminal 76 due to contact with the base end edge of the elastic contact portion 98 is avoided.

The fixing portion 48 of the terminal fitting 112 is superposed on the rear surface of the connector housing 14, and the plate-shaped connecting portion 66 of the crimp terminal 62 provided at the end of the electric wire 60 is superposed on the rear surface of the fixing portion 48. .. Then, the bolt 56 as a fixing member is inserted into the bolt hole 52 of the terminal fitting 112 and the bolt hole 68 of the crimp terminal 62, and the bolt 56 is screwed to the nut portion 84 of the connector housing 14. As a result, the terminal fitting 112 and the crimp terminal 62 fixed to the electric wire 60 are collectively fixed to the connector housing 14 at substantially the same position. The fixing portion 48 of the terminal fitting 112 fixed to the connector housing 14 with the bolt 56 and the plate-shaped connecting portion 66 of the crimp terminal 62 are in contact with each other and overlapped with each other, and the terminal fitting 112 and the electric wire 60 are mutually conducted. ing. The crimp terminal 62 may be arranged so as to be located between the connector housing 14 and the fixing portion 48 of the terminal fitting 112, in other words, to be overlapped on the front surface of the fixing portion 48.

According to the fourth embodiment, the input from the electric wire 60 side to the terminal fitting 112 side is immediately transmitted and received to the connector housing 14, and is difficult to be transmitted to the terminal body portion 94 of the terminal fitting 112. Further, the moment based on the input from the electric wire 60 is unlikely to act on the terminal fitting 112, and the runout and misalignment of the terminal fitting 112 are prevented.

The fixing portion 48 of the terminal fitting 118 bolted to the connector housing 116 and the plate-shaped connecting portion 66 of the crimp terminal 62 are in contact with each other and overlapped with each other, and the terminal fitting 118 and the electric wire 60 are mutually conductive. ..

As a result, the terminal main body 34 of the terminal fitting 118 extends along the axial direction (X direction) of the terminal main body accommodating portion 130, and the plate thickness direction of the terminal main body 34 becomes the vertical direction of the terminal insertion hole 122. As described above, the terminal fitting 118 is housed in the connector housing 116. Further, the pressing rib 132 presses the tip end portion of the terminal body portion 34 toward the lower inner surface of the terminal body portion accommodating portion 130.

According to the fifth embodiment, the terminal fitting 118 is housed in the connector housing 116 so that the plate thickness direction of the terminal body portion 34 is the vertical direction of the terminal insertion hole 122. Therefore, the height of the connector housing 116 itself can be reduced advantageously as compared with the case where the vertical direction of the terminal insertion hole 122 of the connector housing 116 is the plate width direction of the terminal body portion 34. Further, due to a simple structure in which a pair of partition plate portions 126, 126 protruding inward from both side surfaces of the terminal insertion hole 122 are provided, the terminal main body portion 34 and the mating terminal 76 are accommodated in a space-saving state.
