The side wall of the main body 111 is provided with a first opening 111c1 and a second opening (not shown). From the first opening 111c1, the first locking member 131 protrudes toward the outside of the body portion 111. From the second opening, the second locking component 132 protrudes toward the outside of the body portion 111.

A connector insertion port 150 is provided inside the body 111. The connector insertion port 150 is a portion that extends cylindrically from the inner surface of the portion of the body portion 111 facing the hook-type terminal block 200 toward the second surface 112a side. The connector insertion port 150 is exposed to the outside from the housing 110 through an opening 112 b provided in the center of the cover 112, and is freely connected to the connector 330 of the appliance body 310. The top view shape of the connector insertion port 150 is slightly T-shaped, and the connector 330 is also a corresponding shape. The connector insertion port 150 is provided, for example, in the concave portion on the second surface 112a side of the housing 110.

The cover 112 is a plate-shaped component made of resin that covers the lower surface side of the main body 111. The cover 112 constitutes a lower surface (connection surface) of the housing 110, and an opening 112b is provided in the center of the cover 112. From the opening 112b, the connector insertion port 150 and the first operated portion (not shown) of the first lever 161 and the second operated portion (not shown) of the second lever 162 are exposed to the outside.

The first terminal 121, the second terminal 122, and the third terminal 123 are metal plate-shaped components. The first terminal 121, the second terminal 122 and the third terminal 123 are fixed by screws inside the body 111. One end 121 a of the first terminal 121 protrudes from the terminal insertion hole 111 a 1 provided in the housing 110. The other end 121b of the first terminal 121 is arranged in the connector insertion port 150. Similarly, one end 122a of the second terminal 122 protrudes from the terminal insertion hole 111a2 provided in the housing 110. The other end 122b of the second terminal 122 is disposed in the connector insertion port 150. One end 123a of the third terminal 123 protrudes from the terminal insertion hole 111a3 provided in the housing 110, and the other end 123b of the third terminal 123 is disposed in the connector insertion port 150.

The first terminal 121 and the second terminal 122 are a pair of terminals for receiving power supply from the self-leading terminal block 200 of the lighting fixture 300. One end 121a of the first terminal 121 is inserted into the first guide groove 231, and one end 122a of the second terminal 122 is inserted into the second guide groove 232, whereby the first terminal 121 and the second terminal 122 is electrically connected to a pair of power supply terminals in the lead-out terminal block 200. The lighting fixture 300 receives AC power, for example, from the self-leading terminal block 200, but it may receive DC power.

In addition, one end 121 a of the first terminal 121 and one end 122 a of the second terminal 122 are bent in an L-shape, respectively. In a state where one end 121a of the first terminal 121 is inserted into the first guide groove 231 and one end 122a of the second terminal 122 is inserted into the second guide groove 232, if the lighting fixture is turned When the connector 100 is used, the adapter 100 for lighting fixtures is caught on the hook-type terminal block 200. In other words, the first terminal 121 and the second terminal 122 are also used for mechanical connection of the adaptor 100 for lighting equipment and the hook-type terminal block 200.

On the other hand, the third terminal 123 is a ground terminal. By inserting one end 123 a of the third terminal 123 into the third guide groove 233, the third terminal 123 is electrically connected to the ground terminal in the hook-type terminal block 200. Unlike the first terminal 121 and the second terminal 122, one end 123a of the third terminal 123 is not bent, and the third terminal 123 is not used for mechanical connection with the adapter 100 for lighting equipment. However, one end 123a of the third terminal 123 may be bent, and the third terminal 123 may also be used for mechanical connection with the adapter 100 for lighting equipment.

The other end 121b of the first terminal 121, the other end 122b of the second terminal 122, and the other end 123b of the third terminal 123 are connected to the connector 330 in the state of being connected to the connector insertion port 150 The metal terminals in the device 330 are connected.

In addition, the length of the portion protruding from the first surface 111a in one end 123a of the third terminal 123 may be configured to be longer than the length of the portion protruding from the first surface 111a in one end 121a of the first terminal 121 and The length of a portion of one end 122a of the second terminal 122 that protrudes from the first surface 111a is longer. The length here is more specifically the length in the Z-axis direction.

As a result, when the adaptor 100 for a lighting fixture is attached to the hook-type terminal block 200, the third terminal 123 as the ground terminal is easier to contact the terminals in the hook-type terminal block 200 than the first terminal 121 and the second terminal 122. Electrical connection. Thereby, the safety when the adapter 100 for lighting equipment is attached to the hook-type terminal block 200 can be improved.

Similarly, the other end 123b of the third terminal 123 may protrude to the second surface 112a side more than the other end 121b of the first terminal 121 and the other end 122b of the second terminal 122.

As a result, when the appliance body 310 and the adaptor 100 for lighting appliances are electrically connected, the third terminal 123 as the ground terminal is more easily electrically connected to the appliance body 310 than the first terminal 121 and the second terminal 122. Thereby, the safety when the appliance body 310 is attached to the adapter 100 for lighting appliances can be improved.

As shown in FIG. 4, the first terminal 121, the second terminal 122 and the third terminal 123 respectively have one end 121 a, 122 a and 123 a from the terminal insertion holes 111 a 1 and 111 a 2 provided in the first surface 111 a of the housing 110. , 111a3 protruding first protruding portion 121a1, second protruding portion 122a1 and third protruding portion 123a1. The axial lengths H1, H2, and H3 of the first protrusion 121a1, the second protrusion 122a1, and the third protrusion 123a1 are slightly the same. In other words, H1=H2=H3. For example, the axial lengths H1, H2, and H3 of the first protrusion 121a1, the second protrusion 122a1, and the third protrusion 123a1 are slightly in the range of 3.5-20 mm. In other words, 3.5 <H1=H2=H3 <20 mm. The axial lengths H1, H2, and H3 of the first protruding portion 121a1, the second protruding portion 122a1, and the third protruding portion 123a1 may also be slightly in the range of 5-12 mm. In other words, 5 <H1=H2=H3 <12 mm. The axial lengths H1, H2, and H3 of the first protruding portion 121a1, the second protruding portion 122a1, and the third protruding portion 123a1 may also be slightly in the range of 7-8 mm. In other words, 7 <H1=H2=H3 <8 mm.

The axial lengths H1, H2, and H3 of the first protruding portion 121a1, the second protruding portion 122a1, and the third protruding portion 123a1 are slightly the same, whereby the adaptor 100 for lighting fixtures can be made thin. In addition, since the adapter 100 for lighting fixtures is formed to be thin, it can be easily packaged.

In addition, if the length H3 of the third protrusion 123a1 in the axial direction is shorter than the length H1, H2 of the first protrusion 121a1 and the second protrusion 122a1 in the axial direction, the third protrusion 123a1 is inserted into the hook-type terminal block When 200 is in contact with the third connected portion 223b of the third blade receiving 223 described later, there is a problem that the clamping area is insufficient. Moreover, in this case, the third connected portion 223b must be provided in a direction close to the third protruding portion 123a1, and there is also a problem that the third connected portion 223b has insufficient insulation distance.

Therefore, compared to the case where the length H3 of the third protrusion 123a1 in the axial direction is shorter than the lengths H1, H2 of the first protrusion 121a1 and the second protrusion 122a1 in the axial direction, the first protrusion 121a1 and the second The axial lengths H1, H2, and H3 of the protruding portion 122a1 and the third protruding portion 123a1 are slightly the same to ensure the contact area of the third protruding portion 123a1 and the third connected portion 223b of the third blade receiving 223 described later, and A good insertability can be obtained.

FIG. 5 is another embodiment of the first protrusion 121a1, the second protrusion 122a1, and the third protrusion 123a1' of the present invention. As shown in FIG. 5, the third protruding portion 123a1' protrudes toward the first surface 111a side of the first protruding portion 121a1 and the second protruding portion 122a1. In other words, the axial length H3' of the third protruding portion 123a1' is longer than the axial lengths H1, H2 of the first protruding portion 121a1 and the second protruding portion 122a1. In other words, H3'>H2 or H3'>H1. For example, the length H3' of the third protrusion 123a1' in the axial direction is longer than the length H1 of the first protrusion 121a1 in the axial direction by 0.1-10 mm, or by 0.5-5 mm, or by 1- 3 mm range. In other words, the relationship between the length H3' and the length H1 is 0.1 <H3'-H1 <10 mm, or 0.5 <H3'-H1 <5 mm, or 1 <H3'-H1 <3 mm. Similarly, the length H3' of the third protrusion 123a1' in the axial direction is longer than the length H2 of the second protrusion 122a1 in the axial direction by 0.1-10 mm, or by 0.5-5 mm, or by 1 -3 mm range. In other words, the relationship between the length H3' and the length H2 is 0.1 <H3'-H2 <10 mm, or 0.5 <H3'-H2 <5 mm, or 1 <H3'-H2 <3 mm. In this embodiment, the length H1 and the length H2 are slightly the same. In other words, the relationship between the length H1 and the length H2 is H1=H2. However, the length H1 and the length H2 may have different lengths. The axial length H3' of the third protruding portion 123a1' is longer than the axial lengths H1 and H2 of the first protruding portion 121a1 and the second protruding portion 122a1, thereby inserting the adapter 100 for lighting equipment When the hook-type terminal block 200 is reached, the third protruding portion 123a1' can be first aligned with the third guide groove 233, which can facilitate insertion. In addition, the third blade 223 of the hook-type terminal block 200 can also be arranged at a place far away from the first surface 211a, and the insulation distance of the third blade 223 can be increased.

As shown in FIGS. 4 and 5, the first protrusion 121 a 1 of the first terminal 121 has a bent portion 121 a 11. The bent portion 121a11 can be used to hang the adaptor 100 for lighting equipment on the hook-type terminal 200. The curved portion 121a11 of the first terminal 121 is a portion of the first terminal 121 that forms an angle with the axial direction on the axial section. In the present embodiment, the bent portion 121a11 extends in the radial direction of the adapter 100 for lighting equipment. However, the curved portion 121a11 may extend in the horizontal direction, or may extend at an angle with respect to the horizontal direction. In addition, as shown in FIG. 5, the length L1 of the curved portion 121 a 11 in the radial direction may be the same as the length of the portion where the third protrusion 123 a 1 ′ protrudes from the first protrusion 121 a 1 and the second protrusion 122 a 1. In other words, the length L1 may also be slightly equal to the difference between H3' and H1, that is, L1=H3'-H1, or the length L1 may also be slightly equal to the difference between H3' and H2, that is, L1=H3'-H2. Thereby, in the case where the third protruding portion 123a1' also needs to form a curved portion, the third protruding portion 123a1' can be formed by directly bending the portion protruding from the first protruding portion 121a1 and the second protruding portion 122a1 to form the third protruding portion The curved part of 123a1'.

The bent portion 121a11 is formed with a terminal connection portion 121a12 at a portion extending along the radial direction of the adapter 100 for lighting equipment. In the present embodiment, the first terminal 121 is connected by the portion of the terminal connecting portion 121a12 and the first connected portion 221b of the first blade receiving 221 described later.

As shown in FIG. 10, in the plan view, the engaging portion 223b3 is disposed at a position corresponding to the third terminal portion 233c of the third guide groove 233, and the guide portion 223b2 and the opening portion 223b1 are disposed at the position corresponding to the third guide groove The position of the third guide portion 233b of 233. In the plan view, the opening 223b1 does not extend to the position of the third insertion portion 233a. However, the opening 223b1 may extend to the position of the third insertion portion 233a. In this case, as long as the opening portion 223b1 is formed in a shape sufficient to allow the third terminal 123 to pass therethrough and advance to the induction portion 223b2 through the opening portion 223b1. With the above configuration, it can be ensured that the third terminal 123 can be connected to the third connected portion 223b first after being inserted into the third insertion portion 233a. Accordingly, if the third terminal 123 and the third blade receiving 223 are set as the ground terminal and the ground blade receiving, respectively, the third terminal 123 can be connected to the third connected portion 223b after being inserted into the third insertion portion 233a. It is possible to improve the safety when the appliance body 310 is attached to the adapter 100 for lighting appliances.

Moreover, as shown in FIG. 10, the distance D3 between the third blade receiver 223 and the third insertion portion 233a is shorter than the distance D1 between the first blade receiver 221 and the first insertion portion 231a, and is smaller than the distance between the second blade receiver 222 and the second insertion portion 232a is close to D2. Further, as shown in FIG. 10, the angle θ3 between the third blade receiving 223 and the third insertion portion 233a relative to the center position C is smaller than the angle between the first blade receiving 221 and the first insertion portion 231a relative to the central position C θ1 is smaller than the angle θ2 between the second blade 222 and the second insertion portion 232a with respect to the center position C. The distance here more specifically refers to the distance from the center position of the first insertion portion 231a, the second insertion portion 232a, and the third insertion portion 233a to the first blade receiving 221, the second blade receiving 222, and the third blade receiving 223; The angle here refers more specifically to the center positions of the first insertion portion 231a, the second insertion portion 232a, and the third insertion portion 233a relative to the center of the first blade receiving 221, the second blade receiving 222, and the third blade receiving 223 The angle clamped by position C. Thereby, when the third terminal 123 is inserted into the third insertion portion 233a and the third terminal 123 is rotated, the third terminal 123 can be preferentially connected to the third blade 223. If the third terminal 123 and the third blade receiving 223 are set as the ground terminal and the ground blade receiving, respectively, when the third terminal 123 is inserted into the third insertion portion 233a, it can be connected to the third connected portion 223b, which can improve the Safety when the fixture body 310 is attached to the adapter 100 for lighting fixtures.

Moreover, by the engaging portion 223b3 being disposed at a position corresponding to the third terminal portion 233c of the third guide groove 233, when the third terminal 123 is engaged with the engaging portion 223b3, the third terminal portion 233c can restrict the third The terminal 123 advances, and the third terminal 123 is stably engaged with the engaging portion 223b3. In addition, as shown in FIG. 10, in this embodiment, the third terminal portion 233c does not extend to the third base portion 223a, whereby the third terminal 123 can pass through the third terminal portion 233c when it is engaged with the engaging portion 223b3 The third terminal 123 is restricted from advancing.

The opening portion 223b1 is used to receive the third terminal 123 and guide the third terminal 123 to the inducing portion 223b2, the inducing portion 223b2 is used to induce the third terminal 123 to the engaging portion 223b3, and the engaging portion 223b3 is used to engage the third terminal 123 .

As shown in FIG. 10, the opening 223b1 is arranged at a position adjacent to the third insertion portion 233a of the third guide groove 233. The opening 223b1 is formed in a shape that opens toward the third insertion portion 233a. When viewed from the second surface 212a, the openings 223b1 are formed so that the interval increases from the induction portion 223b2 side in the direction opposite to the sandwiching direction (engagement direction). Here, the sandwiching direction (engagement direction) ) Refers to the direction in which the third terminal 123 is sandwiched (engaged) to the third connected portion 223b. Thereby, the third terminal 123 can pass through the opening 223b1 more easily, and the impact of the third terminal 123 on the third blade 223 when passing through the opening 223b1 can be reduced. Specifically, when viewed from the second surface 212a, the opening angle formed by the two blades of the opening 223b1 may be 30 to 150 degrees, 45 to 120 degrees, or 60 to 90 degrees . However, as long as the third terminal 123 can pass through the opening 223b1 more easily, the opening angle formed by the two blades of the opening 223b1 can be adjusted as desired.

The induction portion 223b2 extends from the opening portion 223b1 toward the engagement direction, and is connected to the engagement portion 223b3. The induction portion 223b2 is formed so that the interval becomes smaller in the engagement direction. As a result, when the third terminal 123 passes through the induction part 223b2, the clamping part of the induction part 223b2 generates an additional holding force. When the user engages the adapter 100 for the lighting appliance to the hook-type terminal block 200, You can feel the holding force, and then you can know that the snapping process is indeed going on, which can provide the user with a sense of authenticity when snapping.

The engaging portion 223b3 extends from the inducing portion 223b2 toward the engaging direction, and is connected to the third base portion 223a. The engaging portion 223b3 is formed so that the interval becomes larger in the engaging direction. Thus, when the induction portion 223b2 enters the engaging portion 223b3, it can be known that the third terminal 123 is already located in the engaging portion 223b3. In addition, since the engaging portion 223b3 is disposed at a position corresponding to the third terminal portion 233c of the third guide groove 233, the third terminal 123 can be stably connected to the third terminal portion 233c It is held in the engaging portion 223b3.

In addition, when viewed from the second surface 212a, the guide portion 223b2 and the engaging portion 223b3 are formed in a slightly hourglass shape with a narrow interval between the intermediate portions. With this slightly hourglass-like shape, when the third terminal 123 reaches the engaging portion 223b3 through the inducing portion 223b2, a clicking feeling occurs when the third connected portion 223b is stretched out to recover, thereby, the user It can be known that the adaptor 100 for lighting appliances has been stably engaged with the hook-type terminal block 200. However, as long as the third terminal 123 can be induced and engaged, the shapes of the induction portion 223b2 and the engagement portion 223b3 can be arbitrarily adjusted as required.

In addition, the third base portion 223a is formed with an enlarged portion 223a1 at a place connected to the engaging portion 223b3 of the third connected portion 223b. The enlarged portion 223a1 is formed so that the interval becomes larger in the engagement direction. Thereby, since the enlarged portion 223a1 is formed in such a manner that the interval in the engagement direction becomes larger, the angle formed by the portion where the enlarged portion 223a1 and the third base portion 223a are connected becomes smaller, which in turn causes the third terminal 123 to enter and The opening and closing angle between the third base portion 223a and the enlarged portion 223b4a1 caused by the removal becomes smaller. Therefore, the amount of deformation of the third blade 223 on the third base portion 223a caused by the opening and closing of the third terminal 123 can be reduced by the absorption of the enlarged portion 223b4a1. Thereby, the fatigue deformation or breakage of the third blade 223 due to long-term use can be reduced.

In the present embodiment, the third connected portion 223b has an opening 223b1, a guiding portion 223b2, and an engaging portion 223b3. However, the first connected portion 221b and the second connected portion 222b may be formed with an opening portion 223b1, a guide portion 223b2, and an engaging portion 223b3 similar to the third connected portion 223b.

The positioning portions 213 on one side can position the first blade receiving 221, the second blade receiving 222, and the third blade receiving 223 respectively, and the positioning portions 213 on both sides can prevent the first blade receiving 221, the second The blade 222 and the third blade 223 slide or rotate. In this embodiment, the positioning portion 213 is formed integrally with the housing 210 on the inner wall of the housing 210, but the positioning portion 213 can also be formed separately from the housing 210 by additional positioning protrusions or a positioning element To achieve positioning.

In addition, a restriction portion 215 is further provided on the inner wall of the housing 210, and is provided on the inner wall of the housing 210 so as to restrict the third blade from being excessively deformed by 223. In other words, the housing 210 is formed with the restricting portion 215 for suppressing the interval of the third blade 223 so that the third blade 223 is not excessively deformed. In this embodiment, the restricting portion 215 is a convex portion formed on the inner wall of the housing 210. As shown in FIGS. 8 and 9, the restricting portion 215 is formed between the inner wall of the housing 210 and the third blade 223. In addition, the third connected portion 223b of the third blade 223 is arranged between the restricting portion 215 and the center position C of the housing 210. In this embodiment, the restricting portion 215 is formed integrally with the housing 210 on the inner wall of the housing 210, but the restricting portion 215 may be formed separately from the housing 210.

As shown in FIG. 9, the restricting portion 215 and the third connected portion 223b are arranged with a gap G4. When the blade of the third connected portion 223b is opened to a certain degree, the third connected portion 223b will come into contact with the restricting portion 215, whereby the restricting portion 215 can suppress excessive deformation of the third connected portion 223b. Moreover, a plurality of positioning portions 213 may be formed, for example, between the third connected portion 223b and the inner wall of the housing 210, and between the third connected portion 223b and the center position C of the housing 210, This can more reliably prevent excessive deformation of the third connected portion 223b.

[Configuration of terminal and insertion part]

Next, the group of the first terminal 121, the second terminal 122, and the third terminal 123 in the case where the adapter 100 for a lighting appliance is viewed from the first surface 111a side will be described with reference to FIGS. 11-13, 19, and 20. state.

As shown in FIGS. 11-13, one end 121a of the first terminal 121, one end 122a of the second terminal 122, and one end 123a of the third terminal 123 are from the adapter 100 for lighting appliances The first surface 111a protrudes, and when one end 121a of the first terminal 121, one end 122a of the second terminal 122, and one end 123a of the third terminal 123 are viewed from the side of the first surface 111a, the configuration The three vertices of the triangle. Each of the first end 121a of the first terminal 121, the one end 122a of the second terminal 122, and the one end 123a of the third terminal 123 is to ensure insulation from other terminals or electrically conductive components However, it is necessary to configure at a specified interval. Assume that the first position P1 of one end 121a of the first terminal 121, the second position P2 of one end 122a of the second terminal 122, and the third position P3 of one end 123a of the third terminal 123 are configured On a straight line, the size of the housing 110 in the straight direction may increase. Moreover, the position referred to here (specifically, the first position P1, the second position P2, and the third position P3) refers to, for example, the center position of one end of the terminal viewed from the first surface 111a side (or The coordinates indicated by the central position).

Therefore, in the adaptor 100 for lighting fixtures, the first position P1 of one end 121a of the first terminal 121, the second position P2 of one end 122a of the second terminal 122, and one of the third terminal 123 The third position P3 of the end 123a is not arranged in a straight line. The first position P1, the second position P2, and the third position P3 constitute three vertices of the triangle.

As a result, compared to the case where the first position P1, the second position P2, and the third position P3 are arranged on a straight line in the same direction, the size of the housing 110 in the same direction can be reduced.

In addition, any triangle with the first position P1, the second position P2, and the third position P3 as the three vertices may be used. However, the triangle in the adaptor 100 for lighting fixtures is an isosceles triangle. In other words, the first position P1, the second position P2, and the third position P3 are configured in such a manner as to form three vertices of an isosceles triangle. In other words, the third position P3 is located at the perpendicular to the first position P1 and the second position P2.

Thereby, the distance between the one end 121a of the first terminal 121 and the one end 123a of the third terminal 123 and the one end 122a of the second terminal 122 and the one end 123a of the third terminal 123 The interval between them is equal. In the case where the third terminal 123 is a ground terminal, the distance from each of the one end 121a of the first terminal 121 and the one end 122a of the second terminal 122 to the ground terminal can be easily made equal.

However, in this configuration, it cannot be configured around each of the one end 121a of the first terminal 121, the one end 122a of the second terminal 122, and the one end 123a of the third terminal 123 Conductive components. For example, when viewed from the side of the first surface 111a, it is assumed that the conductive area cannot be configured in a circular area within a radius r from the center of each of the first position P1, the second position P2, and the third position P3. Components. In this case, as shown in FIG. 19, if the first position P1, the second position P2, and the third position P3 are respectively arranged on a straight line with an interval r, the area A surrounded by the thick line cannot Configure the area of conductive components. FIG. 19 is a diagram showing a region where a component having conductivity cannot be arranged when the first position P1, the second position P2, and the third position P3 are arranged on a straight line.

In the case where the first position P1, the second position P2, and the third position P3 are configured as three vertices of an isosceles triangle, the area B surrounded by the thick line in FIG. 20 cannot be configured with conductive components Area. FIG. 20 is a diagram showing a region where conductive components cannot be arranged when the first position P1, the second position P2, and the third position P3 are configured as three vertices of an isosceles triangle.

Here, in FIG. 20, if the length r1 of the vertical line formed from the vertex corresponding to the third position P3 to the opposite bottom edge satisfies the relationship of r1 ≦ 1.13r, the area of the area B in FIG. The area of the area A of 19 is below. In other words, if the length of the base of the isosceles triangle formed by the first position P1, the second position P2, and the third position P3 is 1, then as long as the vertex corresponding to the third position P3 in the isosceles triangle The length of the vertical line formed to the opposite bottom edge may be 1.13 or less. In this way, even if the housing 110 is miniaturized, it is easy to configure components having conductivity. In other words, the housing 110 can be easily miniaturized, and the insulation distances of the first terminal 121, the second terminal 122, and the third terminal 123 can be simultaneously secured. In addition, the minimum value of r1 may be (√3/3)×r, for example.

The above has explained the configuration of the first terminal 121, the second terminal 122, and the third terminal 123 when viewed from the first surface 111a side. In addition, when viewed from the second surface 112a, the position of the other end 121b of the first terminal 121, the position of the other end 122b of the second terminal 122, and the position of the other end 123b of the third terminal 123 It is also composed of three vertices of a triangle. In this case, the position of the other end 121b of the first terminal 121, the position of the other end 122b of the second terminal 122, and the position of the other end 123b of the third terminal 123 may also be configured as isosceles triangles 3 vertices.

Here, the first position P1 of one end 121a of the first terminal 121, the second position P2 of one end 122a of the second terminal 122, and the third position of one end 123a of the third terminal 123 are listed. The configuration relationship of P3. Also, referring to FIG. 10, the first position P1b of the first insertion portion 231a, the second position P2b of the second insertion portion 232a, and the third position P3b of the third insertion portion 233a of the hook-type terminal 200 also apply to the first position The configuration relationship of P1, the second position P2 and the third position P3. 6, the other end portions 221d, 222d, and 223d of the first blade receiving 221, the second blade receiving 222, and the third blade receiving 223 are also applicable to the first position P1, the second position P2, and the third position P3 Configuration relationship.
