The base plate 7 is opened toward one long side, and a slit 8 is provided along the insertion direction of the electrical connection portion 19 of the relay terminal 21 to the plurality of insertion holes 17 so that the vicinity of the center is the bottom. It is formed. A plurality of the slits 8 are arranged along the long side of the base plate 7. The interval of the arrangement of the plurality of slits 8 is set so that the electrical connection portion 19 does not interfere with the slit 8 when the electrical connection portion 19 of the relay terminal 21 inserts the plurality of insertion holes 17. In addition, when one deforming plate 15 is deformed, the intervals between the plurality of slits 8 are set so that the adjacent deforming plates 15 can be prevented from being deformed in conjunction with each other. On one long side of the base plate 7 provided with such a slit 8, a plurality of deformable plates 15 are formed of one continuous member via a fixed end 9.

The plurality of deforming plates 15 each have a first inclined plate 37 and a second inclined plate 39.

The first inclined plate 37 is formed of one member continuous with the base plate 7 via the fixed end 9. The first inclined plate 37 connects the fixed end 9 and the top 11 so as to be inclined upward from the fixed end 9 toward the top 11.

It is deformed so as to increase the angle of the top portion 11 formed on the surface. The deformation of the deformable plate 15 may be a plastic deformation in which the deformed state is maintained, and the elasticity of the free end 13 to be restored toward the fixed end 9 side by releasing the pressing on the free end 13 side. It may be a modification. The deformed plate 15 is provided with a plurality of insertion holes 17.

The plurality of insertion holes 17 are formed in the deformable plate 15 by penetrating each of the first inclined plate 37 and the second inclined plate 39, and are provided in pairs on the entire deformed plate 15. The width of the insertion hole 17 is set to be the same as the diameter of the electrical connection portion 19 so that the electrical connection portion 19 of the relay terminal 21 can be inserted. Further, the shape of the insertion hole 17 is formed in the length direction of the first inclined plate 37 and the second inclined plate 39 so that the deformable plate 15 can be deformed while the electrical connection portion 19 of the relay terminal 21 is inserted. It is formed in an elongated oval shape. If the width of the deformable plate 15 has a margin to maintain the rigidity of the deformable plate 15, the insertion hole 17 is formed in a perfect circle shape larger than the diameter of the electrical connection portion 19 of the relay terminal 21. May be good.

The plurality of insertion holes 17 are aligned with the first inclined plate 37 and the second inclined plate when viewed from the insertion direction of the electrical connection portion 19 of the relay terminal 21 in the state before the deformed plate 15 is deformed. It is provided at 39. The electrical connection portion 19 of the relay terminal 21 is inserted and arranged in such a plurality of insertion holes 17 from the fixed end 9 side to the free end 13 side of the deformable plate 15.

In this state, when the deformable plate 15 is deformed so that the free end 13 is separated from the fixed end 9, the edges of the plurality of insertion holes 17 come into contact with the electrical connection portion 19, and the electric wire 3 and the terminal 5 are relay terminals. It is electrically connected via 21. Such deformation of the deforming plate 15 is performed by the deforming portion 23 provided on the free end 13 side.

The deforming portion 23 is formed of one member continuous with the deforming plate 15 via the free end 13. The deformed portion 23 is bent from the free end 13 toward the top 11 side. Such a deformed portion 23 is in contact with the tip of the electrical connection portion 19 of the relay terminal 21 through which the plurality of insertion holes 17 are inserted. When the deformation portion 23 and the electrical connection portion 19 are in contact with each other and the insertion of the electrical connection portion 19 into the plurality of insertion holes 17 is continued, the deformation portion 23 is pressed in a direction away from the fixed end 9. ..

By pressing the deforming portion 23 by the electrical connecting portion 19, the deforming plate 15 is deformed so that the free end 13 is separated from the fixed end 9. Due to the deformation of the deformation plate 15, the edges of the plurality of insertion holes 17 come into contact with the electrical connection portion 19, and the electric wire 3 and the terminal 5 are electrically connected via the relay terminal 21. By providing the deformable portion 23 on the deformable plate 15 in this way, the work of inserting the electrical connection portion 19 into the plurality of insertion holes 17 and the work of deforming the deformable plate 15 can be performed at the same time, and the assembling property is improved. can do.

Here, when the deforming plate 15 is deformed, the electrical contact points between the terminal 5 and the relay terminal 21 are preferably three points. Specifically, as shown in FIG. 2, the electrical contact points between the terminal 5 and the relay terminal 21 are a plurality of contact points between the electrical connection portion 19 and the deformation portion 23, and the electrical connection portion 19 (here, 2). It is preferable that there are three points of contact points with the edges of the insertion holes 17 and 17 on the top 11 side. By bringing the edges of the insertion holes 17 and 17 on the top 11 side into contact with the electrical connection portion 19, the edges of the insertion holes 17 and 17 on the base plate 7 side and the electrical connection portion 19 are separated from each other. There is. By separating the edges of the insertion holes 17 and 17 on the base plate 7 side from the electrical connection portion 19, the electrical connection portion 19 becomes the base when the electrical connection portion 19 is inserted through the insertion holes 17 and 17. It does not get caught in the edge on the plate 7 side. Therefore, the ease of inserting the electrical connection portion 19 into the insertion hole 17 can be improved.

Such a terminal 5 is housed in the housing 25.

As shown in FIGS. 4 and 5, the housing 25 is made of an insulating material and is formed in a housing shape so as to accommodate the terminal 5 and the plurality of relay terminals 21. The housing 25 includes a terminal accommodating portion 41 and a plurality of relay accommodating portions 43.

In the terminal accommodating portion 41, a plurality of deformation plate 15 sides of the terminal 5 are arranged, and one surface (here, the upper surface) side is opened. A plurality of locking projections 42 that engage with the bottoms of the plurality of slits 8 are projected from the bottom wall of the housing 25 located on the terminal accommodating portion 41 side. The locking projection 42 is a remaining portion of the partition wall 46 located at the bottom of the engagement groove 48 when the engagement groove 48 is formed on the partition wall 46. By engaging with the bottom of the slit 8, the locking projection 42 restricts the terminal 5 from moving toward the terminal accommodating portion 41 in the housing 25. Such a terminal accommodating portion 41 is provided with a deformation space that allows deformation of the deformation plate 15 in a state where the locking projection 42 and the slit 8 are engaged with each other.

Engagement grooves 44 formed to have the same thickness as the base plate 7 of the terminal 5 are formed on both side walls of the terminal accommodating portion 41. By engaging with the base plate 7, the engaging groove 44 regulates the movement of the terminal 5 in the housing 25 in the height direction of the housing 25 (thickness direction of the base plate 7). In addition, the bottom of the engaging groove 44 on the terminal accommodating portion 41 side and the end surface of the base plate 7 on the terminal accommodating portion 41 side come into contact with each other, so that the terminal 5 moves to the terminal accommodating portion 41 side in the housing 25. Regulate that.

The plurality of relay accommodating portions 43 are formed in a quadrangular tubular shape in which the terminal accommodating portion 41 side and the side opposite to the terminal accommodating portion 41 in the length direction are opened so as to communicate with the terminal accommodating portion 41. .. In the plurality of relay accommodating portions 43, adjacent relay accommodating portions 43 are partitioned by a partition wall 46. The relay terminal 21 is inserted into the plurality of relay accommodating portions 43 from the opening on the opposite side of the terminal accommodating portion 41.

Engagement grooves 48 formed to have the same thickness as the base plate 7 of the terminal 5 are formed on both side walls of the partition wall 46 and the housing 25 for partitioning the plurality of relay accommodating portions 43, respectively. The engaging grooves 48 on both side walls of the housing 25 communicate with the engaging grooves 44 of the terminal accommodating portion 41. By engaging with the base plate 7, the engaging groove 48 regulates the movement of the terminal 5 in the housing 25 in the height direction of the housing 25 (thickness direction of the base plate 7). The insertion groove 48 of such an engagement groove 48 is opened on the insertion side of the relay terminal 21.

In such a housing 25, the terminal 5 is a terminal accommodating portion in a state where a plurality of deforming plates 15 are arranged in the openings of the plurality of relay accommodating portions 43 and the base plate 7 is arranged in the openings of the engaging groove 48. It is inserted toward the 41 side and the terminal 5 is accommodated. Here, press-fitting projections 10 are projected on both side surfaces of the base plate 7 of the terminal 5. The press-fitting projection 10 is press-fitted into the inner surface of the engaging groove 48 on both side walls of the housing 25 with the base plate 7 inserted into the engaging groove 48. By press-fitting the press-fitting projection 10 into the engaging groove 48, the terminal 5 is restricted from moving toward the plurality of relay accommodating portions 43 in the housing 25, and the terminal 5 is prevented from falling off from the housing 25. In addition, the press-fitting of the press-fitting projection 10 into the engaging groove 48 restricts the terminal 5 from moving in the housing 25 in the width direction of the housing 25.

With the terminal 5 accommodated in such a housing 25, the relay terminal 21 is inserted into the relay accommodating portion 43 through the opening. By inserting the relay terminal 21, the electrical connection portion 19 is inserted into the plurality of insertion holes 17 of the deformable plate 15, comes into contact with the deformable portion 23, deforms the deformable plate 15, and the electric wire 3 and the terminal 5 are relay terminals. It is electrically connected via 21.

At this time, the relay terminal 21 is engaged with a locking lance 27 flexibly provided in the relay accommodating portion 43, is prevented from coming off from the relay accommodating portion 43, and the arrangement position with respect to the housing 25 is maintained. Therefore, even if the deformable plate 15 is elastically deformed, the deformed state of the deformable plate 15 can be maintained, and the electrical connection reliability between the electric wire 3 and the terminal 5 can be maintained. A detection member 29 is attached to such a housing 25.

Here, in a state where the relay terminal 21 is engaged with the locking lance 27, as described above, the electrical contact point with respect to the electrical connection portion 19 is the deformed portion 23 and the top 11 side of the insertion holes 17 and 17. There are 3 points with the edge of. At such an electrical contact point, even if a tensile force is applied to the electric wire 3, the locking lance 27 bends, the electrical connection portion 19 moves in the direction of exiting from the insertion hole 17, and the deformed plate 15 is restored, the contact is made. The angle of the top 11 is set so that the point contact is maintained.

Specifically, the angle formed by the first inclined plate 37 and the second inclined plate 39 of the top portion 11 is such that the relay terminal 21 is engaged with the locking lance 27, and the electrical connection portion 19 and the insertion holes 17, 17 are formed. It is set to be larger than the minimum angle at which the edge on the top 11 side of the top 11 comes into contact. By setting the angle of the top portion 11 in this way, even if the electrical connection portion 19 moves in the direction of exiting from the insertion hole 17 and the angle of the top portion 11 becomes narrow, the deformation portion 23 with respect to the electrical connection portion 19 and the insertion portion can be inserted. It is possible to maintain contact with the edges of the holes 17 and 17 on the top 11 side. Therefore, the electrical connection reliability between the terminal 5 and the relay terminal 21 can be maintained. It is preferable to set the electrical contact points to the above three points because both electrical connection reliability and ease of insertion can be achieved. However, the electrical contact points are as described above. Not limited to 3 points, 2 points or less, or 4 points or more may be used.

As shown in FIG. 4, the detection member 29 is made of an insulating material and is formed in a shape capable of closing the opening on one side of the housing 25. The detection member 29 is assembled to the housing 25 via a plurality of locking portions 45 respectively formed between the detection member 29 and the housing 25.

The detection unit 47 is projected from the surface of the detection member 29 facing the housing 25 toward the housing 25 side by a single member continuous with the detection member 29.

Such a detection unit 47 comes into contact with the top portion 11 of the deformable plate 15 when the deformation of the deformable plate 15 is insufficient, that is, when the contact between the electrical connection portion 19 and the deformable plate 15 is insufficient. In a state where the detection portion 47 is in contact with the top portion 11, the plurality of locking portions 45 cannot be engaged, and the detection member 29 cannot be assembled to the housing 25.

On the other hand, the detection unit 47 and the top portion 11 of the deformable plate 15 when the deformable plate 15 is completely deformed, that is, when the electrical connection portion 19 and the deformable plate 15 are sufficiently in contact with each other. There is no contact. Therefore, a plurality of locking portions 45 can be engaged with each other, and the detection member 29 can be assembled to the housing 25.

In this way, the detection member 29 can detect the deformed state of the deformable plate 15 and detect the contact state between the electrical connection portion 19 and the deformable plate 15 depending on whether or not it can be assembled to the housing 25. By assembling such a detection member 29 to the housing 25, the reliability of the electrical connection between the electric wire 3 and the terminal 5 can be maintained. In the state where the detection member 29 is assembled to the housing 25, the detection unit 47 may be brought into contact with the top portion 11 of the deformable plate 15 to maintain the deformed state of the deformable plate 15.

In the assembly in the connection structure 1 of the electric wire and the terminal, first, the terminal 5 is accommodated in the housing 25. Next, the relay terminal 21 is inserted into the relay accommodating portion 43 of the housing 25, and the electrical connection portion 19 is inserted into the plurality of insertion holes 17 of the deformed plate 15. Next, the insertion of the relay terminal 21 is continued, the tip of the electric connection portion 19 is brought into contact with the deformable portion 23, the deformable plate 15 is deformed, and the electric wire 3 and the terminal 5 are electrically connected via the relay terminal 21. Connect. Then, the detection member 29 is assembled to the housing 25, and the electrical connection state between the electric wire 3 and the terminal 5 is confirmed depending on whether or not the detection member 29 can be assembled.

In such a connection structure 1 between an electric wire and a terminal, a relay terminal 21 having an electric connection portion 19 electrically connected to the terminal 5 is electrically connected to the electric wire 3. Then, the free end 13 side of the deformable plate 15 comes into contact with the electrical connection portion 19 through which the plurality of insertion holes 17 are inserted, and the deformable portion 23 deforms the deformable plate 15 so as to separate the free end 13 from the fixed end 9. Is provided.

Therefore, the work of inserting the electrical connection portion 19 into the plurality of insertion holes 17 and the work of deforming the deformable plate 15 can be performed at the same time, and the work man-hours can be reduced. Therefore, in such a connection structure 1 of the electric wire and the terminal, the assembling property can be improved.

In addition, by electrically connecting the electric wire 3 and the terminal 5 via the relay terminal 21, it is not necessary to insert the electric wire 3 into the plurality of insertion holes 17. Therefore, electric wires 3 of various sizes can be electrically connected to the terminal 5 without changing the shape of the insertion hole 17.

Further, the housing 25 is provided with a locking lance 27 that engages with the relay terminal 21 in a deformed state and holds the arrangement position of the relay terminal 21 with respect to the housing 25. Therefore, the deformed state of the deformed plate 15 by the relay terminal 21 can be stably maintained, and the electrical connection reliability between the electric wire 3 and the terminal 5 can be maintained.

Further, the housing 25 is assembled with a detection member 29 that can be assembled in a state where the deformable plate 15 is deformed and the deformable plate 15 and the electrical connection portion 19 are electrically connected. Therefore, the electrical connection state between the electric wire 3 and the terminal 5 can be detected depending on whether or not the detection member 29 can be assembled to the housing 25.

Then, the curved surface portion 107 is brought into contact with the electrical connection portion 19 due to the deformation of the deformation plate 15.

In addition, the same symbol is described in the same configuration as the first embodiment, and the configuration and the function description are omitted with reference to the first embodiment. The effects are the same.

As shown in FIGS. 6 to 12, the terminal 5 is made of a conductive material and includes a base plate 109, a deformable plate 15, a plurality of insertion holes 17, and a deformable portion 23. In this embodiment, the terminal 5 is a joint terminal for electrically connecting a plurality of electric wires 3.

The base plate 109 is formed in a rectangular shape, and the short side is arranged along the length direction of the electric wire 3, and the long side is arranged along the arrangement direction of the plurality of electric wires 3. Both sides of the base plate 109 in the length direction are engaged with the engaging grooves 44 of the terminal accommodating portion 41 of the housing 25. The engagement between the base plate 109 and the engaging groove 44 restricts the terminal 5 from moving in the height direction, the front-back direction, and the left-right direction in the housing 25. The base plate 109 may be press-fitted into the engaging groove 44. On the base plate 109, a plurality of deformation plates 15 are formed of one continuous member via the fixed end 9.

Each of the plurality of deforming plates 15 has a bent portion 105 in addition to the first inclined plate 37 and the second inclined plate 39. The bent portion 105 is arranged between adjacent insertion holes 17, 17, and includes a third inclined plate 111, a fourth inclined plate 113, and a top portion 103.

The third inclined plate 111 is formed of one member continuous with the first inclined plate 37 via the top 115. The third inclined plate 111 is inclined toward the electric connection portion 19 side at the top 115 so as to be inclined downward from the top 115 toward the free end 13 side in a symmetrical shape with the first inclined plate 37. Has been done.

The fourth inclined plate 113 is formed of one member continuous with the second inclined plate 39 via the top 117. The fourth inclined plate 113 is inclined toward the second inclined plate 39 so as to be inclined downward from the top 117 toward the fixed end 9 side by bending toward the electrical connection portion 19 side at the top 117. Has been done.

The top 103 connects the third inclined plate 111 and the fourth inclined plate 113 on the opposite side of the top 115 of the third inclined plate 111 and the top 117 of the fourth inclined plate 113. The top portion 103 is projected toward the electrical connection portion 19 by bending the third inclined plate 111 and the fourth inclined plate 113 toward the electrical connection portion 19. The surface of the top 103 on the side of the electrical connection portion 19 is formed in a curved surface. The top 103 is arranged between adjacent insertion holes 17, 17.

The terminal 5 having the deformed plate 15 provided with such a bent portion 105 is accommodated in the terminal accommodating portion 41 of the housing 25 by engaging the base plate 109 with the engaging groove 44. In the terminal 5 housed in the housing 25, the relay terminal 21 is inserted into the housing 25, so that the electrical connection portion 19 of the relay terminal 21 is inserted into the plurality of insertion holes 17. The tip of the electrical connection portion 19 through which the plurality of insertion holes 17 are inserted is brought into contact with the deformed portion 23. When the electrical connection portion 19 and the deformation portion 23 are in contact with each other and the insertion of the electrical connection portion 19 into the plurality of insertion holes 17 is continued, the deformation portion 23 is pressed in a direction away from the fixed end 9.

By pressing the deforming portion 23 by the electrical connecting portion 19, the deforming plate 15 is deformed so that the free end 13 is separated from the fixed end 9. Due to the deformation of the deformable plate 15, the top portion 103 of the bent portion 105 comes into contact with the electrical connection portion 19. In addition, due to the deformation of the deformable plate 15, the edge portion of the plurality of insertion holes 17 facing the top portion 103 of the bent portion 105 with the electrical connection portion 19 interposed therebetween comes into contact with the electrical connection portion 19. By contacting the top 103 of the bent portion 105 and the edges of the plurality of insertion holes 17 with the electrical connection portion 19, the electric wire 3 and the terminal 5 are electrically connected via the relay terminal 21.

In such a terminal 5, when the deforming plate 15 is deformed, there are four electrical contact points between the terminal 5 and the relay terminal 21. Specifically, with respect to the electrical connection portion 19, the deformed portion 23, the edge portion of the plurality of (two in this case) insertion holes 17 and 17 facing the top portion 103 of the bent portion 105, and the top portion 103 of the bent portion 105. And 4 points come into contact. By providing the deformed plate 15 with the bent portion 105 in contact with the electrical connection portion 19 in this way, the electrical contact points between the terminal 5 and the relay terminal 21 can be increased, and the terminal 5 and the relay terminal 21 can be connected to each other. The electrical connection reliability can be improved. Further, by setting the contact point to the top 103 of the bent portion 105, the platings applied to the surfaces of the terminal 5 and the relay terminal 21 are in contact with each other, and it is possible to prevent an increase in resistance due to oxidation of the base material. In addition, by forming the top 103 of the bent portion 105 into a curved surface, it is possible to suppress scratches and generation of wear debris due to contact with the electrical connection portion 19. Further, the edge portion facing the top portion 103 of the bent portion 105 is brought into contact with the electrical connection portion 19 with the electrical connection portions 19 of the plurality of insertion holes 17 interposed therebetween. Therefore, when the deformable plate 15 is deformed, the electrical connection portion 19 can be sandwiched between the edges of the plurality of insertion holes 17 and the top portions 103 of the bending portions 105, and the electrical connection reliability can be maintained. can.

Here, the base material may be exposed at the edge portion of the insertion hole 17 that comes into contact with the electrical connection portion 19, and there is a possibility that resistance increases due to oxidation of the base material. In addition, if the edge of the insertion hole 17 in contact with the electrical connection portion 19 is sharp, scratches or wear debris may be generated when the edge of the insertion hole 17 and the electrical connection portion 19 come into contact with each other. there is a possibility. Therefore, a curved surface portion 107 formed of a curved surface is provided at the edge portion of the insertion hole 17 in contact with the electrical connection portion 19.

The curved surface portion 107 is a portion of the edge portion of the insertion hole 17 that comes into contact with the electrical connection portion 19 when the deformable plate 15 is deformed (here, a portion facing the top portion 103 of the bending portion 105 with the electrical connection portion 19 interposed therebetween. ). The curved surface portion 107 is formed in a curved surface shape by forming a portion of the insertion hole 17 in contact with the electrical connection portion 19 in a flange shape and bending the flange-shaped portion. By forming the portion of the insertion hole 17 in contact with the electrical connection portion 19 as the curved surface portion 107, the plating applied to the surfaces of the terminal 5 and the relay terminal 21 is in contact with each other, and the resistance increases due to the oxidation of the base material. Can be prevented. In addition, when the edge portion of the insertion hole 17 and the electrical connection portion 19 come into contact with each other, it is possible to suppress scratches and generation of wear debris.

The curved surface portion 107 is bent so that the flange-shaped end portion is arranged at a position avoiding interference with the electrical connection portion 19 when the electrical connection portion 19 is inserted into the plurality of insertion holes 17. The direction is set. Specifically, the curved surface portion 107 is bent toward the bent portion 105 side, and the end portion is bent so as to be separated from the electrical connection portion 19. By performing the bending process in this way, when the electrical connection portion 19 is inserted into the plurality of insertion holes 17, the end portion of the curved surface portion 107 does not interfere with the electrical connection portion 19, and the plurality of insertion holes 17 are formed. The electrical connection portion 19 can be stably inserted.

After the relay terminal 21 is inserted into the housing 25 in which the terminal 5 is housed, the detection member 29 is assembled. The detection member 29 is provided so that the terminal accommodating portion 41 of the housing 25 can be opened and closed via the hinge 119.

As shown in FIGS. 11 and 12, if the relay terminal 21 is not sufficiently inserted into the housing 25, the locking lance 27 is not engaged with the relay terminal 21. When the locking lance 27 is not engaged with the relay terminal 21, the deformation plate 15 is not sufficiently deformed, and the heights of the top portions 115 and 117 of the deformation plate 15 in the terminal accommodating portion 41 are high. .. When the detection member 29 is assembled to the housing 25 in a state where the heights of the tops 115 and 117 of the deformable plate 15 are high, the detection portion 47 comes into contact with the tops 115 and 117 (here, only the top 117). In a state where the detection portion 47 is in contact with the top portion 117, the plurality of locking portions 45 cannot be engaged, and the detection member 29 cannot be assembled to the housing 25. Therefore, it can be detected that the deformation plate 15 is not sufficiently deformed and the electrical connection state between the electric wire 3 and the terminal 5 is insufficient.

As shown in FIGS. 7 to 9, when the relay terminal 21 is sufficiently inserted into the housing 25, the locking lance 27 is engaged with the relay terminal 21. In the state where the locking lance 27 is engaged with the relay terminal 21, the deformation plate 15 is sufficiently deformed, and the heights of the top portions 115 and 117 of the deformation plate 15 in the terminal accommodating portion 41 are low. If the detection member 29 is assembled to the housing 25 in a state where the heights of the tops 115 and 117 of the deformable plate 15 are low, the detection portion 47 does not come into contact with the tops 115 and 117. In a state where the detection unit 47 does not abut on the top portions 115 and 117, a plurality of locking portions 45 can be engaged and the detection member 29 can be assembled to the housing 25. Therefore, it can be detected that the deformation plate 15 is sufficiently deformed and the electric connection state between the electric wire 3 and the terminal 5 is sufficient. In the state where the detection member 29 is assembled to the housing 25, the detection unit 47 may be brought into contact with the top portions 115 and 117 of the deformable plate 15 to maintain the deformed state of the deformable plate 15.

In such a connection structure 101 of electric wires and terminals, a bent portion 105 bent so as to have a top 103 protruding toward the electric connection portion 19 is provided between adjacent insertion holes 17 and 17 of the deformed plate 15.

Therefore, the number of electrical contact points between the terminal 5 and the relay terminal 21 can be increased, and the reliability of the electrical connection between the terminal 5 and the relay terminal 21 can be improved. Further, by setting the contact point to the top 103 of the bent portion 105, the platings applied to the surfaces of the terminal 5 and the relay terminal 21 are in contact with each other, and it is possible to prevent an increase in resistance due to oxidation of the base material.

Further, a curved surface portion 107 formed of a curved surface is provided at the edge portion of the plurality of insertion holes 17 in contact with the electrical connection portions 19. Therefore, the plating applied to the surfaces of the terminal 5 and the relay terminal 21 is in contact with each other, and it is possible to prevent an increase in resistance due to oxidation of the base material. Further, when the edge portion of the insertion hole 17 and the electrical connection portion 19 come into contact with each other, it is possible to suppress scratches and generation of wear debris.

Further, a curved surface portion 107 formed of a curved surface is provided at an edge portion of the bent portion 105 facing the top portion 103 of the bent portion 105 with the electrical connection portions 19 of the plurality of insertion holes 17 interposed therebetween. Then, the curved surface portion 107 is brought into contact with the electrical connection portion 19 due to the deformation of the deformation plate 15. Therefore, when the deformed plate 15 is deformed, the electrical connection portion 19 can be sandwiched between the curved surface portion 107 of the plurality of insertion holes 17 and the top portion 103 of the bent portion 105, and the electrical connection reliability is maintained.
