Description

The present invention relates to an electric wire connector for connecting an electric wire to be connected.

As a conventional electric wire connector, a main body member having a main body side insertion hole and a rotating member rotatable around a predetermined rotation axis eccentric with respect to the central axis of the main body side insertion hole and the rotation side insertion hole. , Are known (see, for example, Patent Document 1). Such an electric wire connector is an electric wire defined by the inner peripheral surfaces of the main body side insertion hole and the rotation side insertion hole as the rotating member attached to the main body member rotates from the release posture to the connection posture.

Japanese Unexamined Patent Publication No. 55-041608

In the electric wire connector described in Patent Document 1, since it is necessary to form an end hole and an insertion portion that are fitted to each other in each of the main body member and the rotating member, the configuration of each member becomes complicated and expensive. Will be. Further, since it is necessary to attach the rotating member to the main body member along the rotating shaft, the space adjacent to the portion where the main body side insertion hole of the main body member is formed is formed in the space adjacent to the main body member along the rotating shaft. It is necessary to have a margin so that the portion where the insertion hole on the rotation side of the rotating member is formed can move along the rotation axis, and there is a concern that the size of the instrument will increase.
In addition, since a relatively large frictional force is generated between the edge of the main body member and the insertion portion of the rotating member fitted therein, it is compared with the rotating work of rotating the rotating member from the release posture to the connection posture. There is a concern that a large force will be required and the work will be complicated, for example, requiring a special tool.
In view of this situation, the main problem of the present invention is the inner peripheral surfaces of the main body side insertion hole and the rotation side insertion hole as the rotating member attached to the main body member rotates from the release posture to the connection posture. In the wire connector that grips the wire to be connected by reducing the wire insertion opening specified by the above, it is possible to stably grip the wire to be connected, and the cost and size of the appliance are increased. It is a point of providing a technique for easily carrying out a rotation operation of rotating a rotating member from a release posture to a connection posture.

The first characteristic configuration of the present invention is a main body member having a main body side insertion hole, and a main body member.
A predetermined rotating shaft that is attached to the main body member and has a rotating side insertion hole that is superimposed on the main body side insertion hole and is eccentric with respect to the central axis of the main body side insertion hole and the rotation side insertion hole. Equipped with a rotating member that can rotate around
The wire insertion opening defined by the inner peripheral surfaces of the main body side insertion hole and the rotation side insertion hole as the rotating member attached to the main body member rotates from the release posture to the connection posture. It is an electric wire connector that grips the electric wire to be connected inserted through the electric wire insertion opening by reducing the portion.
The main body member has a main body side contact surface facing the rotation shaft side, and also has a main body side contact surface.
The rotating member has a rotating side outer peripheral surface formed in an arc shape with the rotating shaft as a central axis, and the rotating side outer peripheral surface is brought into contact with the main body side contact surface. Rotate in the state,
In a state where the rotating member attached to the main body member is rotated to the connecting posture, the central axis of the rotating side insertion hole is the main body side contact surface with respect to the central axis of the main body side insertion hole. It is located on the opposite side of.

According to this configuration, the rotating member is attached to the main body member along the direction perpendicular to the rotation axis, and the rotating side outer peripheral surface of the rotating member is in contact with the main body side contact surface of the main body member. The rotating member attached to the main body member can be rotated around the rotation axis in the state of being in contact with the main body member. As a result, in the space adjacent to the portion where the main body side insertion hole of the main body member is formed along the rotation axis, the portion where the rotation side insertion hole of the rotation member is formed becomes the rotation shaft. Since only a gap that allows mounting in the vertical direction is required, the increase in size of the equipment is suppressed. Further, since there is no portion to be fitted to each other as in the conventional case, the frictional force generated between the main body side contact surface of the main body member and the rotation side outer peripheral surface of the rotating member is reduced, and the rotating member is reduced. It is possible to easily carry out the rotation work of rotating from the release posture to the connection posture.

Then, as the rotating member attached to the main body member rotates from the release posture to the connection posture, the electric wire insertion opening defined by the inner peripheral surfaces of the main body side insertion hole and the rotation side insertion hole is opened. In the state where the wire to be connected is gripped by the wire insertion opening in the reduced state, the central axis of the rotation side insertion hole is located on the side opposite to the main body side contact surface with respect to the central axis of the main body side insertion hole. Therefore, a reaction force acts from the gripped electric wire to be connected to the inner peripheral surface of the rotation-side insertion hole in the direction toward the main body-side contact surface. Then, due to the reaction force toward the main body side contact surface, the rotation side outer peripheral surface of the rotating member having the rotation side insertion hole is strongly pressed toward the main body side contact surface of the main body member. Therefore, the rattling of the rotating member with respect to the main body member is suppressed, and the decrease in the gripping force with respect to the electric wire to be connected due to the rattling or the like can be appropriately suppressed.

Therefore, according to the present invention, the electric wire is inserted through the inner peripheral surfaces of the main body side insertion hole and the rotation side insertion hole as the rotating member attached to the main body member rotates from the release posture to the connection posture. In the wire connector that reduces the opening and grips the wire to be connected at the wire insertion opening, it is possible to stably grip the wire to be connected, and the cost and size of the appliance are suppressed to rotate. It is possible to provide a technique that makes it possible to easily carry out a rotation operation of rotating a member from a release posture to a connection posture.

The second characteristic configuration of the present invention is that the main body member has a pair of first main body side contact surfaces and a second main body side contact surfaces that intersect each other as the main body side contact surfaces.

According to this configuration, the rotating member attached to the main body member is placed on the first main body side contact surface and the second main body side contact surface arranged so that the outer peripheral surfaces on the rotation side intersect with each other in the main body member. It can be easily rotated while still in contact. Further, in a state where the rotating member attached to the main body member is rotated to the connection posture to grip the connection target electric wire inserted through the electric wire insertion opening, the inside of the rotation side insertion hole from the gripped connection target electric wire. The direction of the reaction force acting on the peripheral surface is toward the first main body side contact surface and the second main body side contact surface. Then, due to the reaction force, the rotating side outer peripheral surface of the rotating member having the rotating side insertion hole is strongly pressed against the first main body side contact surface and the second main body side contact surface of the main body member, respectively. Will be. Therefore, the rattling of the rotating member with respect to the main body member is further suppressed, and the decrease in the gripping force with respect to the connected electric wire due to the rattling or the like can be further suppressed.

In the third characteristic configuration of the present invention, the main body member has a plurality of main body side insertion hole forming portions in which the main body side insertion holes are formed, and the main body member has a plurality of main body side insertion hole forming portions.
The rotating member has a plurality of rotating side insertion hole forming portions in which the rotating side insertion hole is formed.
The point is that the plurality of main body side insertion hole forming portions and the plurality of rotation side insertion hole forming portions are each formed in a comb-teeth shape in which they mesh with each other.

According to this configuration, a rotating member with respect to the main body member in a state where a plurality of main body side insertion hole forming portions and a plurality of rotating side insertion hole forming portions, each of which is formed in a comb-teeth shape, are meshed with each other. Can be mounted along the direction perpendicular to the axis of rotation. As a result, the rotating member attached to the main body member can be easily rotated around the rotating shaft while appropriately suppressing the deviation along the rotating shaft.
Further, the plurality of main body side insertion holes formed in each of the plurality of main body side insertion hole forming portions and the plurality of rotation side insertion holes formed in each of the plurality of rotation side insertion hole forming portions are alternately arranged. Will be placed in. As a result, the eccentric width of the plurality of main body side insertion holes and the plurality of rotation side insertion holes arranged alternately with the rotation of the rotating member attached to the main body member from the release posture to the connection posture. It is possible to firmly grip the wire to be connected inserted through the wire insertion opening, which shrinks due to the increase in the number of wires, in a form of meandering multiple times, and prevent slipping or disconnection due to the tension of the wire to be connected.

The fourth characteristic configuration of the present invention includes holding means for holding the connection posture of the rotating member in the main body member.
The holding means is provided at a position facing the main body side contact surface.

According to this configuration, the holding means can hold the connecting posture of the rotating member in a form such as preventing the rotating member attached to the main body member from rotating from the connecting posture to the releasing posture. Since the holding means is provided at a position of the main body member facing the contact surface on the main body side, the rotating member attached to the main body member is rotated from the release posture to the connection posture and inserted into the electric wire insertion opening. In the state of gripping the connected wire to be connected, the reaction force acting on the rotating member from the gripped wire to be connected toward the contact surface on the main body side is opposite to the contact surface on the main body side when viewed from the rotating member. It is avoided that it is transmitted to the holding means side located on the side. Therefore, it is possible to appropriately suppress overload and damage of the holding means due to the reaction force from the electric wire to be connected.

An embodiment of the present invention will be described with reference to FIGS. 1 to 4.
As shown in FIG. 1, the electric wire connector 51 according to the present embodiment includes a main body member 10 and a rotating member 20 rotatably attached to the main body member 10.
As shown in FIG. 4, the main body member 10 has a main body side insertion hole 15. On the other hand, the rotating member 20 has a rotating side insertion hole 25 that is superimposed on the main body side insertion hole 15 in a state of being attached to the main body member 10. Then, the rotating member 20 attached to the main body member 10 rotates around a predetermined rotating shaft 20x eccentric with respect to the central shaft 15x of the main body side insertion hole 15 and the central shaft 25x of the rotating side insertion hole 25. It will be possible. By rotating the rotating member 20 attached to the main body member 10 around the rotating shaft 20x in this way, the posture of the rotating member 20 becomes the release posture as shown in FIGS. 2 and 4A. It is changed between the connection posture as shown in FIGS. 3 and 4 (b).

From the release posture of the rotating member 20 attached to the main body member 10 (the posture of the rotating member 20 shown in FIGS. 2 and 4A) to the connecting posture (the rotating member 20 shown in FIGS. 3 and 4B). The eccentric width of the main body side insertion hole 15 and the rotation side insertion hole 25 increases with the rotation to the posture).
That is, as shown in FIG. 4A, in the released state in which the rotating member 20 attached to the main body member 10 is in the released posture, the central shaft 15x of the main body side insertion hole 15 and the center of the rotating side insertion hole 25 The axes 25x are parallel and close to each other, and in this embodiment they are in agreement. Then, as shown in FIG. 4B, in the connected state in which the rotating member 20 attached to the main body member 10 is rotated so that the rotating member 20 is in the connecting posture, the central axis of the main body side insertion hole 15 is formed. The central axis 25x of the rotation side insertion hole 25 shifts to the side away from 15x. Then, the electric wire insertion opening OP defined by the inner peripheral surfaces of the main body side insertion hole 15 and the rotation side insertion hole 25 is reduced. Therefore, by rotating the rotating member 20 attached to the main body member 10 to the connection posture, the wire Ca to be connected inserted into the wire insertion opening OP is gripped by the inner peripheral surface of the reduced wire insertion opening OP. can do.

In the electric wire connector 51 of the present embodiment, a pair of rotating members 20 are attached to one main body member 10, and a pair of electric wires Ca to be connected are connected to each rotating member 20 side. The electric wire Ca to be connected can be connected. Therefore, by manufacturing the main body member 10 and the rotating member 20 with a conductive material, the pair of electric wires Ca to be connected can be electrically connected. The connection directions of the pair of electric wires Ca to be connected to the electric wire connector 51 may be opposite to each other or may be the same direction to each other.
In the following description, one side (right side in FIGS. 1 to 3) of the pair of rotating members 20 attached to the main body member 10 will be mainly described, but the other side may be similarly configured. can.

The diameter and arrangement of the main body side insertion hole 15 and the rotation side insertion hole 25 can be appropriately set according to the size and the like of the electric wire Ca to be connected. Further, a plurality of types of electric wires having similar diameters can be connected by a common electric wire connector 51 having the same diameter and arrangement relationship of the main body side insertion hole 15 and the rotation side insertion hole 25. For example, a wire having a cross-sectional area of 5.5 SQ and a wire having a diameter of 2.6 mm can be connected by a common wire connector 51, and a wire having a cross-sectional area of 8 SQ and a wire having a diameter of 3.2 mm can be connected. Can be connected by a common electric wire connector 51, and each of an electric wire having a cross-sectional area of 14 SQ and an electric wire having a diameter of 4 mm can be connected by a common electric wire connector 51.

The above is the basic configuration of the electric wire connecting tool 51. The electric wire connecting tool 51 of the present embodiment can stably grip the electric wire Ca to be connected, suppresses the cost increase and the size increase of the appliance, and rotates. It has a characteristic configuration that makes it possible to easily carry out the rotation work of the moving member 20. The details of the feature configuration will be described below.

As shown in FIGS. 2 and 3, the main body member 10 has main body side contact surfaces 16A and 16B facing the rotation shaft 20x (see FIG. 4) side.
That is, the main body member 10 includes a plate-shaped base plate portion 11, a plate-shaped partition plate portion 12 vertically erected from the central portion thereof, and a base plate portion 11 directed from the tip end portion of the partition plate portion 12 to both sides. It is configured as a substantially H-shaped member in a side view including a plate-shaped locking plate portion 13 extending in parallel with the above. Then, the rotating member 20 is attached to each space between the base plate portion 11 and the locking plate portion 13 on both sides of the partition plate portion 12.
The main body member 10 has a flat first main body side contact surface 16A which is a surface of the partition plate portion 12 on the rotating member 20 side and a flat first main body side contact surface 16A which is a surface of the base plate portion 11 on the rotating member 20 side. The two main body side contact surfaces 16B are provided as a pair of main body side contact surfaces 16A and 16B that intersect each other perpendicularly.

On the other hand, as shown in FIGS. 2 and 3, the rotating member 20 has a rotating side outer peripheral surface 26 formed in an arc shape with the rotating shaft 20x (see FIG. 4) as the central axis. In the state of being attached to the main body member 10, the rotation side outer peripheral surface 26 can be rotated in a state of being in contact with each of the pair of main body side contact surfaces 16A and 16B intersecting each other.
That is, the rotating member 20 is configured as a member having a substantially oval cross section, and a pair of main bodies in which the arcuate rotating side outer peripheral surface 26 formed on one end side thereof intersects with each other of the main body member 10. It becomes rotatable around the rotation shaft 20x (see FIG. 4) in a state of being in contact with the side contact surfaces 16A and 16B, respectively.

In the electric wire connector 51 of the present embodiment, the rotating member 20 rotates 90 ° around the rotating shaft 20x (see FIG. 4) to achieve the release posture shown in FIG. 2 (or FIG. 4A). It is configured to change the posture from the connection posture shown in FIG. 3 (or FIG. 4 (b)). Further, regarding the rotation direction from this release posture to the connection posture, the portion of the rotation side outer peripheral surface 26 of the rotating member 20 that is in contact with the first main body side contact surface 16A in the release posture is the connection posture. In the direction of contact with the second main body side contact surface 16B (counterclockwise direction in FIGS. 4A and 4B).

As shown in FIG. 1, in the main body member 10, a plurality of main body side insertion hole forming portions 14 formed over the partition plate portion 12 and the base plate portion 11 are arranged side by side, and these plurality of main body side insertions are provided. An insertion hole 15 on the main body side is formed as a round hole in each of the hole forming portions 14.
On the other hand, in the rotating member 20, a plurality of rotating side insertion hole forming portions 24 are arranged side by side at the end portion on the rotating shaft 20x side, and each of the plurality of rotating side insertion hole forming portions 24 has a plurality of rotating side insertion hole forming portions 24. The rotation side insertion hole 25 is formed as a round hole.

Each of the plurality of main body side insertion hole forming portions 14 and the plurality of rotating side insertion hole forming portions 24 is formed in a comb-teeth shape in which they mesh with each other. Then, from the separated state in which the main body member 10 and the rotating member 20 are separated as shown in FIG. 1, the plurality of main body side insertion hole forming portions 14 and the plurality of rotating side insertion holes are as shown in FIG. The rotating member 20 can be attached to the main body member 10 along the direction perpendicular to the rotating shaft 20x in a state where the forming portion 24 is meshed with each other. With this configuration, the rotating member 20 attached to the main body member 10 can be easily rotated around the rotating shaft 20x while appropriately suppressing the deviation along the rotating shaft 20x.

Further, in the present embodiment, the second main body side contact surface 16B is formed on the outer side of the main body side insertion hole forming portion 14 arranged on the outermost side, but the main body into which the rotation side insertion hole forming portion 24 is inserted. The second main body side contact surface 16B is omitted between the adjacent side insertion hole forming portions 14. This facilitates attachment of the rotating member 20 to the main body member 10 while avoiding interference of the rotating side insertion hole forming portion 24 with respect to the second main body side contact surface 16B.

As a result, in the space adjacent to the main body side insertion hole forming portion 14 of the main body member 10 along the rotation shaft 20x, the rotation side insertion hole forming portion 24 of the rotation member 20 is perpendicular to the rotation shaft 20x. It is configured as a gap having only a width that allows it to be attached in any direction, which suppresses the increase in size of the device. Further, since the main body member 10 and the rotating member 20 do not have a portion to be fitted to each other, the main body side contact surfaces 16A and 16B of the main body member 10 and the rotating side outer peripheral surface 26 of the rotating member 20 respectively. The frictional force generated between the two is reduced, and the rotation work of rotating the rotating member 20 from the releasing posture to the connecting posture can be easily performed.

Further, a plurality of main body side insertion holes 15 formed in each of the plurality of main body side insertion hole forming portions 14, and a plurality of rotation side insertion holes 25 formed in each of the plurality of rotation side insertion hole forming portions 24. Will be arranged alternately along the rotation shaft 20x. As a result, the release posture of the rotating member 20 attached to the main body member 10 (the posture of the rotating member 20 shown in FIGS. 2 and 4A) is changed to the connecting posture (shown in FIGS. 3 and 4B). Due to the increase in the eccentric width between the plurality of main body side insertion holes 15 and the plurality of rotation side insertion holes 25 arranged alternately with the rotation to the posture of the rotating member 20), the insertion holes 15, 25 The wire insertion opening P defined by the inner peripheral surfaces of the respective wires is reduced. Then, the connection target electric wire Ca inserted through the electric wire insertion opening OP is firmly gripped by the inner peripheral surface of the electric wire insertion opening OP in a form of meandering a plurality of times.

As shown in FIGS. 3 and 4B, the rotating member 20 attached to the main body member 10 is connected to the position where the main body side contact surfaces 16A and 16B face each other in the main body member 10. A holding means 30 for holding the connection posture (see FIGS. 3 and 4 (b)) of the rotating member 20 in the state is provided. That is, in the rotating member 20, a locked portion 22a formed as a step portion is provided on the other end side opposite to the one end side on which the rotating side outer peripheral surface 26 is formed. On the other hand, a locking claw 13a is provided on the rotating member 20 side of the tip of the locking plate portion 13 of the main body member 10. Then, when the rotating member 20 rotates from the releasing posture to the connecting posture, the locking claw 13a of the main body member 10 becomes the locked portion 22a of the rotating member 20 with elastic deformation of the locking plate portion 13. Locked. As a result, the connection posture of the rotating member 20 (the posture of the rotating member 20 shown in FIGS. 3 and 4B) is maintained, and the releasing posture (the rotating member shown in FIGS. 2 and 4A) is maintained. It will be prevented from returning to the posture of 20). The width and thickness of the locking plate portion 13 are set so that the locking plate portion 13 can be appropriately elastically deformed when the locking claw 13a is locked to the locked portion 22a. Further, in the present embodiment, the base plate portions 11 on both sides are connected to each other at positions displaced from each other at the tip portion of the partition plate portion 12.

In the electric wire connector 51 of the present embodiment, in the connected state in which the rotating member 20 attached to the main body member 10 is rotated to the connecting posture (see FIGS. 3 and 4B), the rotating side insertion hole 25 is used. The main body side insertion with respect to the rotation shaft 20x so that the central shaft 25x of the main body side is located on the opposite side of the main body side contact surfaces 16A and 16B that intersect each other with respect to the central shaft 15x of the main body side insertion hole 15. The hole 15 and the rotation side insertion hole 25 are arranged.

Specifically, as shown in FIG. 4A, in the released state in which the rotating member 20 attached to the main body member 10 is in the released posture, the central shaft 15x of the main body side insertion hole 15 and the rotation side insertion hole The central shaft 25x of 25 is arranged at a position close to the second main body side contact surface 16B while maintaining the distance from the first main body side contact surface 16A with respect to the rotation shaft 20x. Further, in the present embodiment, the main body side insertion hole 15 and the rotation side insertion hole 25 are formed so that the positions of the central axes 15x and 25x in the released state are the same and the diameters are the same.
Therefore, in this released state, the opening area of the electric wire insertion opening OP defined by the inner peripheral surfaces of the main body side insertion hole 15 and the rotation side insertion hole 25 is the main body side insertion hole 15 and the rotation side insertion. It is considered to be relatively large like the hole 25, and the wire Ca to be connected can be easily inserted into this relatively wide wire insertion opening OP.

When the main body side insertion hole 15 and the rotation side insertion hole 25 are arranged in this way, the main body side is in a connected state in which the rotation member 20 attached to the main body member 10 is in the connection posture as shown in FIG. 4 (b). The central shaft 15x of the insertion hole 15 does not move, and the central shaft 25x of the rotation side insertion hole 25 rotates 90 ° around the rotation shaft 20x, so that the position of the central shaft 25x in the released state (FIG. 4). (See (a)) as a starting point, the contact surface 16A on the first main body side and the contact surface 16B on the second main body side are displaced in a direction away from each other.
Then, in this connection state, the opening area of the wire insertion opening OP defined by the inner peripheral surfaces of the main body side insertion hole 15 and the rotation side insertion hole 25 is smaller than the opening area in the above-mentioned release state. The connection target electric wire Ca inserted into the electric wire insertion opening OP is gripped by the inner peripheral surface of the electric wire insertion opening OP.

Then, in the connection state shown in FIG. 4B, the first main body side contact surface 16A and the second main body side contact surface 16A where the central shaft 25x of the rotation side insertion hole 25 intersects with each other with respect to the central shaft 15x of the main body side insertion hole 15. It will be located on the opposite side of each of the main body side contact surfaces 16B. As a result, a reaction force is applied to the inner peripheral surface of the rotating side insertion hole 25 from the gripped electric wire Ca to be connected in the direction toward the first main body side contact surface 16A and the second main body side contact surface 16B, respectively. Works. Then, due to the reaction force toward each of the first main body side contact surface 16A and the second main body side contact surface 16B, the rotation side outer peripheral surface 26 of the rotation member 20 having the rotation side insertion hole 25 becomes the main body. The member 10 is strongly pressed against the first main body side contact surface 16A and the second main body side contact surface 16B, respectively. Therefore, the rattling of the rotating member 20 with respect to the main body member 10 is suppressed, and the decrease in the gripping force with respect to the connection target electric wire Ca due to the rattling or the like is appropriately suppressed.

Further, since the holding means 30 is provided at the tip end portion of the locking plate portion 13 which is a portion of the main body member 10 where the first main body side contact surface 16A and the second main body side contact surface 16B face each other. In the connection state shown in FIG. 4B, the reaction force acting on the rotating member 20 from the gripped electric wire Ca to be connected toward the main body side contact surfaces 16A and 16B, respectively, is the second from the rotating member 20. It is avoided that the transmission is transmitted to the holding means 30 side located on the opposite side of each of the 1 main body side contact surface 16A and the 2nd main body side contact surface 16B. Therefore, overload and damage of the holding means 30 due to the reaction force from the electric wire Ca to be connected are appropriately suppressed.

The hole 15 and the rotation side insertion hole 25 are arranged, but as shown in FIGS. 5 and 6, the central shaft 25x of the rotation side insertion hole 25 becomes the central shaft 15x of the main body side insertion hole 15 in the connected state. On the other hand, the main body side insertion hole 15 and the rotation side insertion hole 25 may be arranged with respect to the rotation shaft 20x so as to be located on the side opposite to only one side of the main body side contact surfaces 16A and 16B. No.

For example, in the arrangement example shown in FIG. 5, as shown in FIG. 5A, in the released state in which the rotating member 20 attached to the main body member 10 is in the released posture, the central axis 15x of the main body side insertion hole 15 is used. The central shaft 25x of the rotation side insertion hole 25 is arranged at a position close to both the first main body side contact surface 16A and the second main body side contact surface 16B when viewed from the rotation shaft 20x. Further, in this arrangement example, the main body side insertion hole 15 and the rotation side insertion hole 25 are formed so that the positions of the central axes 15x and 25x in the released state are the same and the diameters are the same.
Therefore, in this released state, the opening area of the electric wire insertion opening OP defined by the inner peripheral surfaces of the main body side insertion hole 15 and the rotation side insertion hole 25 is the main body side insertion hole 15 and the rotation side insertion. It is considered to be relatively large like the hole 25, and the wire Ca to be connected can be easily inserted into this relatively wide wire insertion opening OP.

When the main body side insertion hole 15 and the rotation side insertion hole 25 are arranged in this way, as shown in FIG. 5B, in the connected state in which the rotation member 20 attached to the main body member 10 is in the connection posture, the main body side The central shaft 15x of the insertion hole 15 does not move, and the central shaft 25x of the rotation side insertion hole 25 rotates 90 ° around the rotation shaft 20x, so that the position of the central shaft 25x in the released state (FIG. 5). Starting from (a)), the distance from the second main body-side contact surface 16B is maintained, and the distance is shifted in the direction away from the first main body-side contact surface 16A.
Then, in this connection state, the opening area of the wire insertion opening OP defined by the inner peripheral surfaces of the main body side insertion hole 15 and the rotation side insertion hole 25 is smaller than the opening area in the above-mentioned release state. The connection target electric wire Ca inserted into the electric wire insertion opening OP is gripped by the inner peripheral surface of the electric wire insertion opening OP.

Then, in the connection state shown in FIG. 5B, the central shaft 25x of the rotation side insertion hole 25 is located on the side opposite to the first main body side contact surface 16A with respect to the central shaft 15x of the main body side insertion hole 15. Therefore, a reaction force acts from the gripped electric wire Ca to be connected to the inner peripheral surface of the rotation-side insertion hole 25 in the direction toward the first main body-side contact surface 16A. Then, due to the reaction force, the rotation side outer peripheral surface 26 of the rotation member 20 having the rotation side insertion hole 25 is strongly pressed toward the first main body side contact surface 16A of the main body member 10.

On the other hand, in the arrangement example shown in FIG. 6, as shown in FIG. 6A, in the released state in which the rotating member 20 attached to the main body member 10 is in the released posture, the central shaft 15x of the main body side insertion hole 15 is used. The central shaft 25x of the rotation-side insertion hole 25 is arranged at a position close to the second main body-side contact surface 16B while being away from the first main body-side contact surface 16A when viewed from the rotation shaft 20x. Further, in this arrangement example, the main body side insertion hole 15 and the rotation side insertion hole 25 are formed so that the positions of the central axes 15x and 25x in the released state are the same and the diameters are the same.
Therefore, in this released state, the opening area of the electric wire insertion opening OP defined by the inner peripheral surfaces of the main body side insertion hole 15 and the rotation side insertion hole 25 is the main body side insertion hole 15 and the rotation side insertion. It is considered to be relatively large like the hole 25, and the wire Ca to be connected can be easily inserted into this relatively wide wire insertion opening OP.

When the main body side insertion hole 15 and the rotation side insertion hole 25 are arranged in this way, as shown in FIG. 6B, in the connected state in which the rotation member 20 attached to the main body member 10 is in the connection posture, the main body side The central shaft 15x of the insertion hole 15 does not move, and the central shaft 25x of the rotation side insertion hole 25 rotates 90 ° around the rotation shaft 20x, so that the position of the central shaft 25x in the released state (FIG. 6). Starting from (a)), the distance from the first main body-side contact surface 16A is maintained, and the distance is shifted in the direction away from the second main body-side contact surface 16B.
Then, in this connection state, the opening area of the wire insertion opening OP defined by the inner peripheral surfaces of the main body side insertion hole 15 and the rotation side insertion hole 25 is smaller than the opening area in the above-mentioned release state. The connection target electric wire Ca inserted into the electric wire insertion opening OP is gripped by the inner peripheral surface of the electric wire insertion opening OP.

Then, in the connection state shown in FIG. 6B, the central shaft 25x of the rotation side insertion hole 25 is located on the side opposite to the second main body side contact surface 16B with respect to the central shaft 15x of the main body side insertion hole 15. Therefore, a reaction force acts from the gripped electric wire Ca to be connected to the inner peripheral surface of the rotation-side insertion hole 25 in the direction toward the second main body-side contact surface 16B. Then, due to the reaction force, the rotation side outer peripheral surface 26 of the rotation member 20 having the rotation side insertion hole 25 is strongly pressed toward the second main body side contact surface 16B of the main body member 10.

(2) In the above-described embodiment, the diameters of the main body-side insertion hole 15 formed in the main body member 10 and the rotation-side insertion hole 25 formed in the rotating member 20 are the same.
