Description

Technical Field

[0001] The present invention relates to a terminal.

Background Art

[0002] Conventionally, a technique is known in which a terminal crimped to an end of an electric wire is housed in a terminal housing chamber formed in a housing.

[0003] Patent Document 1 discloses a configuration in which a lance that can be elastically displaced in a direction intersecting the insertion direction of a terminal is formed in a terminal housing chamber.

[0004] When inserting a terminal into the terminal housing chamber, as the terminal is inserted, the lance interferes with the terminal and elastically displaces. When the terminal is inserted to the housing position where it is electrically connected to the mating terminal in the terminal housing chamber, the lance elastically returns and locks to the terminal. Thereby, the terminal can be housed in the terminal housing chamber.

Summary of the Invention

Problems to be Solved by the Invention

[0006] When a plurality of terminal housing chambers are formed in a housing, it may be necessary to insert a new terminal into the terminal housing chamber to be inserted while terminals are housed in the surrounding terminal housing chambers.

[0007] In this case, the operator needs to perform the insertion work with a narrow field of view while scraping aside the electric wires existing around the terminal housing chamber to be inserted.

[0008] Therefore, when an operator pinches the portion crimped to the electric wire of the terminal and pushes the terminal into the terminal housing chamber to be inserted, since the insertion work is performed with a narrow field of view, it is difficult to insert the terminal horizontally, and diagonal insertion of the terminal is likely to occur. When diagonal insertion of the terminal causes buckling of the electric wire, semi-insertion of the terminal, etc., there is a possibility that the insertion work may be hindered, such as having to redo the insertion work.

[0009] The present invention has been made in view of the problems of such prior art. And the object of the present invention is to provide a terminal that can easily perform the insertion work while preventing diagonal insertion of the terminal even when inserting a new terminal into the terminal housing chamber to be inserted with terminals housed in the surrounding terminal housing chambers in a housing in which a plurality of terminal housing chambers are formed.

Means for Solving the Problems

[0010] A terminal according to an aspect of the present invention includes a base portion that extends along an axial direction and has an electric wire placement surface for placing an electric wire, a core wire crimping portion formed at a first portion of the base portion and crimped to a core wire exposed from an insulating coating of the electric wire, a coating crimping portion formed at a second portion of the base portion and crimped to the insulating coating, a terminal portion having a flat plate-shaped connecting portion extending along the axial direction from an end portion on the second portion side of the base portion, and a cylindrical holding portion extending along the axial direction from the connecting portion. When an external force is applied to the holding portion in a direction intersecting the axial direction, the connecting portion breaks.

Effects of the Invention

[0011] According to the present invention, in a housing in which a plurality of terminal housing chambers are formed, even when inserting a new terminal into the terminal housing chamber to be inserted with terminals housed in the surrounding terminal housing chambers, it is possible to provide a terminal that can easily perform the insertion work while preventing diagonal insertion of the terminal.

MODE FOR CARRYING OUT THE INVENTION

[0013] Hereinafter, the terminal according to the present embodiment will be described in detail with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for convenience of explanation and may be different from the actual ratios. Also, the same or similar reference numerals are given to the same functions and configurations, and the description thereof will be omitted as appropriate.

[0014] [Configuration of Terminal] First, the configuration of the terminal 1 will be described with reference to FIGS. 1 to 4. FIG. 1 is a perspective view of the terminal 1 as viewed from the rear. FIG. 2 is a perspective view of the terminal 1 as viewed from the front. FIG. 3 is a plan view of the terminal 1. FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 3

[0015] Note that the X direction shown in FIGS. 1 to 4 corresponds to the axial direction AD (see FIG. 3) of terminal 1. The Y direction shown in FIGS. 1 to 4 corresponds to the width direction of terminal 1 and is orthogonal to the X direction. The Z direction shown in FIGS. 1 to 4 corresponds to the height direction of terminal 1 and is orthogonal to the X and Y directions.

[0016] Also, the +X side and -X side shown in FIGS. 1 to 4 correspond to the front and rear of terminal 1, respectively. The +Y side and -Y side shown in FIGS. 1 to 4 correspond to the right and left of terminal 1, respectively, when facing the front of terminal 1. The +Z side and -Z side shown in FIGS. 1 to 4 correspond to the upper and lower of terminal 1, respectively.

[0017] Terminal 1 is formed by subjecting a metal plate to pressing or the like. As shown in FIGS. 1 and 2, terminal 1 includes a terminal portion 10, a connecting portion 30, and a holding portion 50. Terminal 1 is crimped to an electric wire at the terminal portion 10. Terminal 1 is held by an operator at the holding portion 50. The connecting portion 30 connects the terminal portion 10 and the holding portion 50. Note that in this embodiment, terminal 1 may be held by a working machine such as a robot arm at the holding portion 50.

[0018] [Configuration of Terminal Portion] The terminal portion 10 has a base portion 11, a core wire crimping portion 13, a covering crimping portion 15, and a connecting portion 17. As shown in FIG. 3, the base portion 11 has a wire mounting surface 11a, a tapered surface 11b, and a contact surface 11c along the axial direction AD (X direction) of terminal 1. The wire mounting surface 11a is the surface on which the electric wire is mounted when terminal 1 is crimped to the electric wire, and is disposed on the -X side of the base portion 11.

[0019] The tapered surface 11b is connected to the wire placement surface 11a on the -X side and is connected to the contact surface 11c on the +X side. The width (length in the Y direction) of the tapered surface 11b increases from the wire placement surface 11a toward the contact surface 11c. The contact surface 11c is the surface where the terminal 1 contacts the mating terminal when the terminal 1 is inserted into the terminal housing chamber of the housing, and is disposed on the +X side of the base portion 11. The contact surface 11c has a contact portion 12 at the center. On the contact surface 11c, the contact portion 12 bulges in the height direction (Z direction) of the terminal 1.

[0020] The base portion 11 has a first portion P1, a second portion P2, and a third portion P3. The first portion P1 and the second portion P2 are located on the +X side and the -X side of the wire placement surface 11a, respectively. The third portion P3 is located on the contact surface 11c.

[0021] A core wire crimping portion 13 is formed in the first portion P1 of the base portion 11. In the present embodiment, the core wire crimping portion 13 has a pair of core wire clamping pieces 13a, 13a. The core wire clamping pieces 13a, 13a extend upward (+Z side) from both sides (+Y side end and -Y side end) of the first portion P1 of the base portion 11. The core wire clamping pieces 13a, 13a are clamped to the core wire exposed from the insulating coating of the wire when the terminal 1 is crimped to the wire. Thereby, the core wire crimping portion 13 is crimped to the core wire of the wire. In this way, by clamping the core wire clamping pieces 13a, 13b, the cross section perpendicular to the axial direction AD in the first portion P1 of the base portion 11 is configured in a substantially closed cross-sectional shape. Note that the configuration for crimping the core wire crimping portion 13 to the core wire of the wire is not limited to the core wire clamping pieces 13a, 13a, and other configurations may be used.

[0022] At the second portion P2 of the base portion 11, a covering crimping portion 15 is formed. In the present embodiment, the covering crimping portion 15 has a pair of covering clamping pieces 15a, 15a. The covering clamping pieces 15a, 15a extend upward (+Z side) from both sides (+Y side end portion and -Y side end portion) of the second portion P2 of the base portion 11. When the terminal 1 is crimped to the electric wire, the covering clamping pieces 15a, 15a are clamped to the insulation coating of the electric wire. Thereby, the covering crimping portion 15 is crimped to the insulation coating of the electric wire. In this way, by clamping the covering clamping pieces 15a, 15b, the cross section perpendicular to the axial direction AD at the second portion P2 of the base portion 11 is configured in a substantially closed cross-sectional shape. Note that the configuration of crimping the covering crimping portion 15 to the insulation coating of the electric wire is not limited to the covering clamping pieces 15a, 15a, and other configurations may be used.

[0023] At the third portion P3 of the base portion 11, a connection portion 17 is formed. In the present embodiment, the connection portion 17 has a pair of connection pieces 17a, 17a. The connection pieces 17a, 17a extend upward (+Z side) from both sides (+Y side end portion and -Y side end portion) of the third portion P3 of the base portion 11, and the tip portions are bent toward the contact portion 12 side (-Z side) of the contact surface 11c. When the terminal 1 is inserted into the terminal housing chamber, the mating terminal is sandwiched between the tip portions of the connection pieces 17a, 17a and the contact portion 12 of the contact surface 11c. Thereby, the connection portion 17 is electrically connected to the mating terminal. Note that the configuration of electrically connecting the connection portion 17 to the mating terminal is not limited to the connection pieces 17a, 17a, and other configurations may be used.

[0024] [Configuration of the connecting portion] As shown in FIG. 4, the connecting portion 30 is formed in a flat plate shape and has an upper surface 31 and a lower surface 33. The upper surface 31 and the lower surface 33 are two surfaces along the axial direction AD in the connecting portion 30 in a sectional view along the axial direction AD of the terminal 1. That is, the upper surface 31 and the lower surface 33 are the +Z side surface and the -Z side surface of the connecting portion 30, respectively.

[0025] The upper surface 31 is connected to the wire placement surface 11a of the base portion 11 on the +X side of the connecting portion 30, and is connected to the side surface 51 of the holding portion 50, which will be described later, on the -X side of the connecting portion 30. Thus, in the terminal 1, the upper surface 31 is formed flush with the wire placement surface 11a, the tapered surface 11b, the contact surface 11c excluding the contact portion 12, and the side surface 51 of the holding portion 50.

[0026] The lower surface 33 is connected to the back surface of the base portion 11 on the +X side of the connecting portion 30, and is orthogonal to the first opening surface 53 of the holding portion 50, which will be described later, on the -X side of the connecting portion 30.

[0027] Also, as shown in FIG. 3, in the plan view of the terminal 1, the width (length in the Y direction) of the connecting portion 30 is smaller than the width (length in the Y direction) of the second portion P2 of the base portion 11, and is smaller than the width (length in the Y direction) of the holding portion 50. Thus, in the plan view of the terminal 1, the shape changes discontinuously between the connecting portion 30 and the second portion P2 of the base portion 11, and the shape changes discontinuously between the connecting portion 30 and the holding portion 50.

[0028] [Configuration of the holding portion] As shown in FIGS. 3 and 4, the holding portion 50 is formed in a cylindrical shape and has a side surface 51, a first opening surface 53, and a second opening surface 55. The first opening surface 53 is located on the +X side of the holding portion 50 and is orthogonal to the axial direction AD of the terminal 1. The second opening surface 55 is located on the -X side of the holding portion 50 and is orthogonal to the axial direction AD of the terminal 1. In the holding portion 50, the internal space surrounded by the side surface 51 communicates with the outside through the first opening surface 53 and the second opening surface 55.

[0029] In the holding portion 50, the cross-section of the holding portion 50 perpendicular to the axial direction AD of the terminal 1 is formed to become smaller along the axial direction AD toward the connecting portion 30 side. For this reason, among the cross-sections of the holding portion 50 perpendicular to the axial direction AD of the terminal 1 in the holding portion 50, the first opening surface 53 is the smallest cross-section, and the second opening surface 55 is the largest cross-section. Note that since the holding portion 50 is formed by subjecting a metal plate to pressing or the like, when the portion of the metal plate to be formed into the holding portion 50 is bent to the -Z side, there may be a narrow gap at the lower end (-Z side end) of the holding portion 50 without both sides of the portion coming into complete contact. Thus, the cross-section of the holding portion 50 perpendicular to the axial direction AD is configured in a substantially closed cross-sectional shape.

[0030] [Configuration of Terminal Crimped to Electric Wire] Next, with reference to FIGS. 5 to 7, the configuration of the terminal 1 crimped to the electric wire 100 will be described. FIG. 5 is a perspective view of the terminal 1 crimped to the electric wire 100. FIG. 6 is a cross-sectional view of the terminal 1 crimped to the electric wire 100 along the axial direction. FIG. 7 is a cross-sectional view of the terminal 1 crimped to the electric wire 100 along the axial direction after the connecting portion 30 is broken.

[0031] As shown in FIGS. 5 and 6, the electric wire 100 has a core wire 101 and an insulating coating 103. The core wire 101 is covered with the insulating coating 103. At the terminal of the electric wire 100, the core wire 101 is exposed from the insulating coating 103.

[0032] When the terminal 1 is crimped to the electric wire 100, the terminal of the electric wire 100 is placed on the wire placement surface 11a of the base portion 11 in the terminal portion 10 from the -X side of the terminal portion 10. Specifically, at the terminal of the electric wire 100, the core wire 101 exposed from the insulating coating 103 is disposed in a region including the first portion P1 of the base portion 11, and the insulating coating 103 is disposed in a region including the second portion P2 of the base portion 11.

[0033] In this state, the core wire crimping portion 13 formed at the first portion P1 of the base portion 11 is crimped to the core wire 101. In the present embodiment, the tip portions of the core wire clamping pieces 13a and 13a are bent toward the wire mounting surface 11a side (-Z side) and clamped to the core wire 101.

[0034] Similarly, the coating crimping portion 15 formed at the second portion P2 of the base portion 11 is crimped to the insulating coating 103. In the present embodiment, the tip portions of the coating clamping pieces 15a and 15a are bent toward the wire mounting surface 11a side (-Z side) and clamped to the insulating coating 103.

[0035] Thereby, the terminal 1 is crimped to the wire 100. Note that the insulating coating 103 of the wire 100 is in contact with the upper surface 31 of the connecting portion 30 and the side surface 51 of the holding portion 50 on the -X side of the terminal 1.

[0036] As shown in FIG. 7, in the terminal 1, the connecting portion 30 is formed in a flat plate shape and is located between the second portion P2 of the base portion 11 and the holding portion 50, which are configured in a substantially closed cross-sectional shape. When an external force acts in a direction intersecting the axial direction AD of the terminal 1, the second portion P2 of the base portion 11 and the holding portion 50, which are configured in a substantially closed cross-sectional shape, are less likely to deform than the flat plate-shaped connecting portion 30. Therefore, when an external force is applied to the holding portion 50 in a direction intersecting the axial direction AD of the terminal 1, stress concentrates on the connecting portion 30, and the connecting portion 30 breaks. In the present embodiment, the direction in which the external force is applied is the -Z side in the height direction (Z direction) of the terminal 1. Due to the breakage of the connecting portion 30, the connecting portion 30 separates into a portion 30a on the second portion P2 side of the base portion 11 and a portion 30b on the holding portion 50 side.

[0037] [Insertion operation of terminal] Next, with reference to FIGS. 8 and 9, the insertion operation of the terminal 1 will be described. FIG. 8 is a diagram for explaining the state before the terminal 1 is inserted into the terminal housing chamber 210 to be inserted. FIG. 9 is a diagram for explaining the state after the terminal 1 is inserted into the terminal housing chamber 210 to be inserted. The housing 200 is provided, for example, in an electrical connection box such as a relay box or a connector such as a multi-pole connector. As shown in FIG. 8, a plurality of terminal housing chambers 210 are formed in the housing 200.

[0038] In this embodiment, for example, during manufacturing or use, with the terminals accommodated in the terminal accommodation chamber 210 disposed around the terminal accommodation chamber 210 to be inserted, the terminal 1 is inserted into the terminal accommodation chamber 210 to be inserted (see FIG. 8). Note that the axial direction AD of the terminal 1 corresponds to the insertion direction of the terminal 1.

[0039] The operator pinches the holding portion 50 of the terminal 1 while pushing aside the electric wires existing around the terminal accommodation chamber 210 to be inserted, and inserts the terminal 1 into the terminal accommodation chamber 210 to be inserted from the rear in the insertion direction of the terminal 1. In the terminal 1, the holding portion 50 is provided rearward in the insertion direction of the terminal 1 than the terminal portion 10. For this reason, even when there are electric wires around the terminal accommodation chamber 210 to be inserted, the operator can horizontally insert the terminal 1 into the terminal accommodation chamber 210 to be inserted, aiming at the opening of the terminal accommodation chamber 210 to be inserted, from the rear in the insertion direction of the terminal 1. Therefore, even when performing the insertion operation of the terminal 1 while pushing aside the electric wires existing around the terminal accommodation chamber 210 to be inserted, diagonal insertion of the terminal 1 can be prevented.

[0040] As shown in FIG. 9, the terminal accommodation chamber 210 to be inserted is provided with a lance 221 and a mating terminal 223. When the terminal 1 is inserted into the terminal accommodation chamber 210 to be inserted, with the insertion of the terminal 1, the lance 221 elastically displaces by interfering with the terminal 1. In this embodiment, with the insertion of the terminal 1, the lance 221 interferes with the connection pieces 17a, 17a of the terminal portion 10 and elastically displaces to the side opposite to the terminal 1.

[0041] When the terminal 1 is inserted to the accommodation position where it is electrically connected to the mating terminal 223, the lance 221 elastically returns and locks to the terminal 1. In this embodiment, when the lance 221 elastically returns, it is locked to the rear ends of the connection pieces 17a, 17a of the terminal portion 10. In this state, the mating terminal 223 is sandwiched between the tip portions of the connection pieces 17a, 17a and the contact portion 12 of the contact surface 11c. Thereby, the terminal 1 is electrically connected to the mating terminal 223. Note that when the terminal 1 is inserted to the accommodation position of the terminal accommodation chamber 210 to be inserted, the connecting portion 30 and the holding portion 50 are located outside the terminal accommodation chamber 210 to be inserted.

[0042] When the operator inserts the terminal 1 to the accommodation position of the terminal accommodation chamber 210 to be inserted, an external force is applied to the holding portion 50 in a direction intersecting the axial direction AD of the terminal 1 to break the connecting portion 30. Thereby, the holding portion 50 is cut off from the connecting portion 30, and it is possible to prevent interference with the electric wire existing around the terminal accommodation chamber 210 to be inserted.

[0043] [Operation and Effect] According to this embodiment, the terminal 1 includes a terminal portion 10, a connecting portion 30, and a holding portion 50. The terminal portion 10 extends along the axial direction AD of the terminal 1 and has a base portion 11, a core wire crimping portion 13, and a covering crimping portion 15. The base portion 11 has a wire mounting surface 11a on which the electric wire 100 is mounted. The core wire crimping portion 13 is formed at the first portion P1 of the base portion 11 and is crimped to the core wire 101 exposed from the insulating coating 103 of the electric wire 100. The covering crimping portion 15 is formed at the second portion P2 of the base portion 11 and is crimped to the insulating coating 103.

[0044] The connecting portion 30 is formed in a flat plate shape and extends along the axial direction AD of the terminal 1 from the end portion on the second portion P2 side of the base portion 11. The holding portion 50 is formed in a cylindrical shape and extends along the axial direction AD of the terminal 1 from the connecting portion 30. The connecting portion 30 breaks when an external force is applied to the holding portion 50 in a direction intersecting the axial direction AD of the terminal 1.

[0045] With the above-described configuration, the cylindrical holding portion 50 is provided behind the insertion direction of the terminal 1. Therefore, an operator can grasp the holding portion 50 and insert the terminal 1 into the terminal housing chamber 210 to be inserted from behind in the insertion direction of the terminal 1, and can perform the insertion operation with a wide field of view from a location away from the terminal housing chamber 210 to be inserted. Therefore, even when there is an electric wire around the terminal housing chamber 210 to be inserted, it becomes easier to horizontally insert the terminal 1 into the terminal housing chamber 210 to be inserted, preventing the diagonal insertion of the terminal 1, and preventing buckling of the electric wire 100, half-insertion of the terminal 1, etc.

[0046] In the case of a conventional terminal, when inserting the terminal into the terminal housing chamber 210 to be inserted from behind in the insertion direction of the terminal, the operator has to grasp the electric wire and perform the insertion operation. In this case, if the rigidity of the electric wire is weak, there is a possibility that the electric wire may buckle due to the insertion resistance of the lance 221.

[0047] Also, with the above-described configuration, since the connecting portion 30 is formed in a flat plate shape and the holding portion 50 is formed in a cylindrical shape, when an external force acts in a direction intersecting the axial direction AD of the terminal 1, the holding portion 50 is less likely to deform than the connecting portion 30. Therefore, when an external force is applied to the holding portion 50 in a direction intersecting the axial direction AD of the terminal 1, stress concentrates on the connecting portion 30 and the connecting portion 30 breaks. Therefore, after inserting the terminal 1 into the terminal housing chamber 210 to be inserted, the holding portion 50 can be easily cut from the connecting portion 30, preventing the holding portion 50 from interfering with the electric wire existing around the terminal housing chamber 210 to be inserted.

[0048] In this way, by using the terminal 1, even when inserting a new terminal into the terminal housing chamber 210 to be inserted in a state where terminals are accommodated in the surrounding terminal housing chambers 210 in a housing 200 in which a plurality of terminal housing chambers 210 are formed, the insertion operation can be easily performed while preventing the diagonal insertion of the terminal.

[0049] According to the present embodiment, in a plan view of the terminal 1, the length of the connecting portion 30 in the width direction perpendicular to the axial direction AD of the terminal 1 is smaller than the length of the second portion P2 of the base portion 11 in the width direction, and is also smaller than the length of the holding portion 50 in the width direction.

[0050] With the above-described configuration, in a plan view of the terminal 1, the shape changes discontinuously between the connecting portion 30 and the second portion P2 of the base portion 11, and the shape changes discontinuously between the connecting portion 30 and the holding portion 50. For this reason, when an external force is applied to the holding portion 50 in a direction intersecting the axial direction AD of the terminal 1, stress is more concentrated on the connecting portion 30, and the connecting portion 30 is likely to break. Therefore, after the terminal 1 is inserted into the terminal housing chamber 210 of the insertion target, the holding portion 50 can be more easily cut from the connecting portion 30.

[0051] According to the present embodiment, in a cross-sectional view along the axial direction AD of the terminal 1, the upper surface 31 along the axial direction AD of the connecting portion 30 is connected to the wire placement surface 11a of the base portion 11 and the side surface 51 of the holding portion 50.

[0052] With the above-described configuration, in the terminal 1, the upper surface 31 of the connecting portion 30 is formed flush with the wire placement surface 11a of the base portion 11 and the side surface 51 of the holding portion 50. For this reason, when the wire 100 is placed on the wire placement surface 11a of the base portion 11, it is possible to avoid the connecting portion 30 and the holding portion 50 from interfering with the wire 100.

[0053] According to the present embodiment, the cross section of the holding portion 50 perpendicular to the axial direction AD becomes smaller along the axial direction AD toward the connecting portion 30 side.

[0054] With the above-described configuration, when an operator pinches the holding portion 50 and pushes the terminal 1 into the terminal housing chamber 210 of the insertion target, the pushing force can be concentrated in the insertion direction of the terminal 1. Therefore, the terminal 1 can be more easily pushed into the terminal housing chamber 210 of the insertion target.

[0055] [Modification Example] In the above-described embodiment, in the holding portion 50, the cross-section of the holding portion 50 perpendicular to the axial direction AD of the terminal 1 was formed to become smaller along the axial direction AD toward the connecting portion 30 side, but it is not limited to this.

[0056] FIG. 10 is a perspective view of the terminal 1a according to this modification. The X-axis, Y-axis, and Z-axis shown in FIG. 10 respectively correspond to the axial direction, width direction, and height direction of the terminal 1a. Also, the +X side and -X side shown in FIG. 10 respectively correspond to the front and rear of the terminal 1a. The +Y side and -Y side shown in FIG. 10 respectively correspond to the right and left of the terminal 1 toward the front of the terminal 1a. The +Z side and -Z side shown in FIG. 10 respectively correspond to the upper and lower of the terminal 1a.

[0057] As shown in FIG. 10, the terminal 1a includes a terminal portion 10, a connecting portion 30, and a holding portion 150. Since the configurations of the terminal portion 10 and the connecting portion 30 have been described in the above-described embodiment, the description thereof will be omitted.

[0058] The holding portion 150 is formed in a cylindrical shape and has a side surface 151, a first opening surface 153, and a second opening surface 155. The first opening surface 153 is located on the +X side of the holding portion 150 and is perpendicular to the axial direction of the terminal 1a. The second opening surface 155 is located on the -X side of the holding portion 150 and is perpendicular to the axial direction of the terminal 1a. In the holding portion 150, the internal space surrounded by the side surface 151 communicates with the outside through the first opening surface 153 and the second opening surface 155.

[0059] In the holding portion 150, the cross-section of the holding portion 150 perpendicular to the axial direction of the terminal 1a is constant along the axial direction. For this reason, among the cross-sections of the holding portion 150 perpendicular to the axial direction of the terminal 1a in the holding portion 150, the first opening surface 153 and the second opening surface 55 are of the same size.

[0060] According to this modification, the cross-section of the holding portion 150 perpendicular to the axial direction is constant along the axial direction.

[0061] With the above-described configuration, when the holding portion 150 is formed by subjecting the metal plate to pressing or the like, it can be formed more simply, so that the manufacturing operation of the terminal can be performed efficiently.
