Description

  The present application relates to connectors.

  There is known an operation terminal of a type attached to a wall of a building, such as a remote controller for a ceiling type air conditioner or an operation panel of a water heater. The operation terminal has a control board in the terminal. The control board is screwed to the electric wire drawn out from the inside of the wall to which the operation terminal is attached, thereby fixing the electric wire and electrically connecting the power source and the signal.

JP 2002-170605 A

  In the above configuration, when connecting the electric wire to the control board, the electric wire is once pulled out from the wall, and then screwed to the connecting portion formed on the control board using a tool such as a screwdriver, and then drawn out. The control board is attached to the operation terminal while returning the electric wire to the inside of the wall. That is, since it is necessary to connect the wires and handle the extra length in a limited place along the wall, the operation is difficult and complicated, and improvement in workability is demanded.

  From the above, there is a demand for connectorization in order to improve workability when connecting electric wires, and the connector is required to be able to easily connect (hold and conduct) the electric wires.

  The connector which concerns on one aspect is a connector which connects an electric wire and an external electrode, Comprising: The position which covers the electric wire mounting part which inserts and mounts the said electric wire in a predetermined electric wire insertion direction, and a part of said electric wire mounting part A base having a terminal support portion disposed on the first contact leg, a first contact leg that can contact the electric wire, a second contact leg that can contact the external electrode, the first contact leg, and the second A contact leg that is folded and connected, and is supported by the terminal support part and curved, and the first contact leg part, the second contact leg part, and the connection part are elastically deformable, A terminal arranged so as to be able to swing while being supported by the terminal support part, and the terminal comes into contact with the electric wire by inserting the electric wire into the electric wire mounting part. A part of the second contact leg protrudes outside the base.

  The terminal support portion may have a curved surface portion on the near side in the electric wire insertion direction, and the connection portion may be supported by the curved surface portion of the terminal support portion and bend along the curved surface portion.

  In the first state in which a part of the electric wire is inserted into the electric wire attachment part, the first contact leg is in contact with the electric wire, and the terminal is in the second state in which the electric wire is attached to the electric wire attachment part. In the state where the first contact leg is in contact with the electric wire, a part of the second contact leg protrudes outside the base to be able to contact the external electrode, and in the second state, In the third state where the second contact leg is in contact with the external electrode, the second contact leg is pressed to the inside of the base by the external electrode, and the first contact leg, the second contact leg, and the The first contact leg portion may apply a biasing force to the electric wire by elastically deforming the connection portion.

  The base has a swing restricting portion that contacts the second contact leg in the second state and restricts the swing of the terminal toward the outside of the base, and the terminal is in the second state. In the state where the second contact leg portion is in contact with the swing restricting portion, the first contact leg portion and the second contact leg portion are elastically deformed so that the first contact leg portion is brought into contact with the electric wire. A biasing force may be applied.

  In the third state, the terminal may be disposed at a position where a tip portion of the second contact leg portion is separated from the electric wire in the electric wire insertion direction.

  The wire mounting portion may include a positioning portion that contacts the tip of the wire and positions the wire.

  The positioning portion may be disposed at a position that blocks between the electric wire and the tip end portion of the second contact leg portion in the third state.

  The terminal may have a dimension from the connection part to a tip part of the first contact leg part shorter than a dimension from the connection part to the tip part of the second contact leg part.

  The terminal may include a bent portion that protrudes to the outside of the base body between the connection portion and a tip portion of the second contact leg portion.

  In the terminal, a tip end portion of the first contact leg portion may be bent toward the electric wire side.

  The terminal may have a concave portion having a shape corresponding to the shape of the electric wire at a distal end portion of the first contact leg portion.

  The terminal may have an extension portion extending to the electric wire insertion direction side in the first contact leg portion.

  The extension portion may be provided on both sides of the first contact leg portion.

  The base has a flat portion on a side in the electric wire insertion direction with respect to the electric wire mounting portion, the electric wire mounting portion is formed in a concave shape with respect to the flat portion, and the terminal is connected to the first contact. The tip of the leg may be disposed on the wire mounting portion, and the extending portion may be disposed on the flat portion.

  The tip of the extension part may be separated from the flat part.

  The terminal may include an engaging portion that protrudes on both sides of the second contact leg portion, and the base may include an engaging protrusion that engages with the engaging portion.

  The base body may have a flange portion arranged at a position covering an end portion on the near side in the electric wire insertion direction in the electric wire mounting portion.

  Since the first contact leg portion of the terminal comes into contact with the electric wire by inserting and attaching the electric wire to the electric wire attaching portion, the connector can easily conduct between the electric wire and the terminal. In addition, the connector is elastically deformed by bringing the external electrode into contact with the second contact leg while the electric wire is attached to the electric wire attachment part, and the first contact leg is in contact with the electric wire and attached to the electric wire. Since the urging force is applied to the part side, the electric wire can be easily held on the base. For this reason, the work of pulling out the electric wire from the wall, the work of screwing the electric wire with a tool to the connection part of the external board, the work of attaching the external board while returning the drawn electric wire to the inside of the wall, etc. The electric wire can be attached with a simple operation. Thereby, workability | operativity at the time of connecting an electric wire can be improved, and an electric wire can be connected (a holding | maintenance and conduction | electrical_connection) easily.

(Embodiment)
FIG. 1 is an exploded perspective view showing a configuration of a connector 100 according to the embodiment. FIG. 2 is a perspective view of the connector 100. FIG. 3 is a perspective view of the connector 100 when viewed from an angle different from that in FIG. FIG. 4 is a cross-sectional view of the connector 100.

  As shown in FIGS. 1 to 4, the connector 100 electrically connects the electric wire 30 and the external electrode 41 of the external substrate 40. In the following, the electric wire 30 includes a wiring for connecting the external substrate 40 to an external power source. The electric wire 30 includes a conductive portion 31 exposed at the tip and a covering portion 32 that covers the conductive portion 31. The external substrate 40 is mounted on an operation terminal attached to a wall of a building, such as a remote controller for a ceiling type air conditioner or an operation panel for a water heater. An operation terminal is not limited to what is attached to the wall part of a building. When the operation terminal includes a display device such as a liquid crystal panel, the external substrate 40 may include a circuit that controls the display device.

  The connector 100 includes a base 10 and terminals 20. The base 10 is formed in a rectangular block shape. The mounting surface 10 a of the base 10 is mounted on the external substrate 40. A groove 10b is formed on the mounting surface 10a. Two groove portions 10 b are provided in parallel along the long side direction of the substrate 10. The groove portion 10b is provided in a range from one end surface 10f in the longitudinal direction of the base body 10 to the other end surface 10e. The groove portion 10b includes a flat surface portion 10c and a curved portion 10h provided on the bottom portion, and a side surface portion 10d. The curved portion 10h is curved in a concave shape with respect to the flat portion 10c.

  The base 10 includes an electric wire mounting portion 11, a terminal support portion 12, a jig insertion portion 13, a swing restriction portion 14, and a boss portion 16. The electric wire mounting part 11 is provided in the bending part 10h of each groove part 10b. The electric wire mounting portion 11 is a portion that extends linearly along the longitudinal direction of the groove portion 10b. In the embodiment, for example, two wire mounting portions 11 are arranged side by side in the short side direction of the base body 10.

  The electric wire mounting portion 11 includes a support portion 11a and a support portion 11b (see FIG. 4). The support parts 11a and 11b are provided in the bending part 10h. The support part 11 a supports the conductive part 31 of the electric wire 30. The support part 11 b supports the covering part 32 of the electric wire 30. The support portions 11a and 11b may have, for example, a cylindrically curved shape according to the outer shape of the conductive portion 31 and the covering portion 32. In this case, the support part 11 a and the support part 11 b can have different diameters depending on the diameters of the conductive part 31 and the covering part 32 of the electric wire 30. For example, the conductive portion 31 has a smaller diameter than the covering portion 32. For this reason, the diameter of the support part 11a can be made smaller than the diameter of the support part 11b. The electric wire mounting portion 11 can be mounted with the electric wire 30 in a state where the conductive portion 31 is supported by the support portion 11a and the covering portion 32 is supported by the support portion 11b. The electric wire mounting part 11 is arrange | positioned in the state with which the support part 11a and the support part 11b were continued in the linear direction (refer FIG.1 and FIG.4). The electric wire mounting portion 11 can insert the electric wire 30 from the end surface 10f of the base 10 toward the end surface 10e along the linear direction in which the support portion 11a and the support portion 11b are continuous. Hereinafter, the direction in which the electric wire 30 is inserted is referred to as an electric wire insertion direction D.

  The wire mounting part 11 has a positioning part 15. The positioning unit 15 positions the electric wire 30 in contact with the tip 31 a of the conductive unit 31. The positioning portion 15 has an end surface 15a in the protruding direction. The end surface 15a is a part of the flat surface portion 10c of the groove portion 10b.

  The terminal support portion 12 is disposed at a position covering a part of the wire mounting portion 11. In the embodiment, the terminal support portion 12 is disposed at a position covering a part of the support portion 11a. The terminal support portion 12 is provided for each wire mounting portion 11. The terminal support unit 12 supports the terminal 20. The terminal support portion 12 is bridged between the opposing side surface portions 10d of each groove portion 10b. Since the terminal support part 12 is arranged at a distance from the conductive part 31 of the electric wire 30, it does not interfere with the conductive part 31 supported by the support part 11a.

  The terminal support portion 12 includes a curved surface portion 12a and a deformation support portion 12b. The curved surface portion 12 a is provided on the front side in the wire insertion direction D of the terminal support portion 12. The curved surface portion 12a is formed in a smooth curved surface shape protruding toward the front side in the electric wire insertion direction D. The deformation support portion 12 b is provided on the wire mounting portion 11 side in the back end portion in the wire insertion direction D of the terminal support portion 12. The deformation support portion 12b may be, for example, an edge portion such as a corner portion (see FIG. 4 and the like), a shape with a chamfered edge portion, or a curved surface shape.

  The terminal support 12 has an inclined protrusion 12c and a side support 12d on the front side in the electric wire insertion direction D with respect to the curved surface 12a (see FIG. 1 and the like). The inclined protrusion 12c protrudes from the side surface 10d on both sides of the groove 10b to the inside of the groove 10b. The inclined protrusion 12c is provided so that the amount of protrusion gradually increases from the near side to the far side in the electric wire insertion direction D. The side portion support portion 12d is disposed between the inclined protrusion portion 12c and the curved surface portion 12a. The side portion support portion 12d is a portion protruding from the side surface portion 10d on both sides of the groove portion 10b to the inside of the groove portion 10b, and is formed in a planar shape parallel to the side surface portion 10d. The side part support part 12d provided in one side part 10d and the side part support part 12d provided in the other side part 10d are disposed to face each other. A step 12e is formed between the inclined protrusion 12c and the side support 12d.

  The jig insertion portion 13 is provided on the end surface 10 e of the base body 10. The jig insertion part 13 penetrates from the end surface 10e to the groove part 10b. The jig insertion portion 13 is formed to have a dimension capable of inserting a jig 50 for removing the electric wire 30.

  The swing restricting portion 14 restricts the swing of the terminal 20. The swing restricting portion 14 includes the inner surface 13 a of the jig insertion portion 13 in the base body 10. The inner surface 13a is, for example, an inner peripheral surface of the jig insertion portion 13, and is a surface disposed to face a virtual surface obtained by extending the flat portion 10c of the groove portion 10b to the jig insertion portion 13 side.

  The boss portion 16 is disposed on the fixed surface 10g opposite to the mounting surface 10a. The boss portion 16 can be fitted into an opening of a case to which the connector 100 is attached. The connector 100 is fixed in a state where the fixing surface 10g is in contact with the case by fitting the boss 16 into the opening of the case.

  FIG. 5 is a perspective view showing the terminal 20. The terminal 20 is formed in a plate shape using a conductive material such as metal. The terminal 20 includes a first contact leg portion 21, a second contact leg portion 22, and a connection portion 23. The terminal 20 is folded at the connection portion 23. In the terminal 20, the first contact leg portion 21, the second contact leg portion 22, and the connection portion 23 are integrated. The terminal 20 is disposed in a state in which the connection portion 23 is fitted in a portion surrounded by the curved surface portion 12a of the terminal support portion 12, the inclined protrusion portion 12c (or the step portion 12e), and the side portion support portion 12d. And it is supported in the state hung on the curved surface part 12a. The terminal 20 is connected by being inserted into the back side in the wire insertion direction D along the groove 10b with the first contact leg portion 21 and the second contact leg portion 22 facing the back side in the wire insertion direction D. The part 23 gets over between the inclined protrusions 12c and is fitted into the side support part 12d, so that the inner surface of the connection part 23 comes into contact with the curved surface part 12a. The terminal 20 is swingably provided while being supported by the terminal support portion 12.

  The first contact leg 21 is elastically deformable. The first contact leg portion 21 has a base portion 21a and a tip portion 21b. The base 21a is planar. The base portion 21 a extends from the connection portion 23 in the linear direction. The tip portion 21b is bent toward the electric wire mounting portion 11 side. The distal end portion 21b has a smaller dimension in the width direction than the base portion 21a. In the embodiment, the width direction of the distal end portion 21b is a direction perpendicular to the electric wire insertion direction D and along the surface of the distal end portion 21b. A step portion (jig locking portion) 21c is provided between the base portion 21a and the tip portion 21b. The stepped portions 21c are provided on both sides in the width direction. The step part 21c can contact a jig 50 described later. FIG. 6 is a partial side view of the terminal 20. As shown in FIG. 6, the end portion 21 b is arranged such that the edge portion 21 e faces the conductive portion 31 of the electric wire 30. As for the 1st contact leg part 21, the edge part 21e of the front-end | tip part 21b can contact the electroconductive part 31 of the electric wire 30. FIG.

  The 2nd contact leg part 22 is arrange | positioned in the state which pinched | interposed the terminal support part 12 between the 1st contact leg parts 21 (refer FIG. 4). The second contact leg portion 22 is elastically deformable. The second contact leg portion 22 has a base portion 22a and a tip portion 22b. The base 22a is planar. The base portion 22a extends from the connection portion 23 in the linear direction. The base 22a has a bent portion 22c. The base 22a is bent toward the first contact leg 21 at the bent portion 22c. The bent portion 22c protrudes in a direction away from the first contact leg portion 21 with respect to the distal end portion 22b. The tip 22b is bent in a direction away from the first contact leg 21.

  As for the 2nd contact leg part 22, the front-end | tip part 22b can contact the inner surface 13a. For example, the tip portion 22b may be configured such that the edge portion contacts the inner surface 13a or may be configured to contact the inner surface 13a. The distal end portion 22 b of the second contact leg portion 22 is provided so as to be able to swing between the swing restricting portion 14 and the positioning portion 15. When the tip portion 22b comes into contact with the swing restricting portion 14, the swing of the tip portion 22b to the outside of the base body 10 is restricted. When the tip portion 22b comes into contact with the positioning portion 15, the swing of the tip portion 22b toward the inside of the base body 10 is restricted.

  The connection part 23 connects the first contact leg part 21 and the second contact leg part 22 so as to be folded back. The connecting portion 23 is supported in a state where it is hung on the curved surface portion 12 a of the terminal support portion 12. The connection portion 23 is curved along the curved surface portion 12 a of the terminal support portion 12 on the near side in the electric wire insertion direction D. Therefore, the connection part 23 has a smooth curved surface on the front side in the electric wire insertion direction D. The connecting portion 23 is formed so that the dimension in the width direction is smaller than that of the first contact leg portion 21 and the second contact leg portion 22 and larger than the interval between the inclined protrusion portions 12c. For this reason, the terminal 20 is easy to be attached to the terminal support portion 12, and is difficult to come out to the near side in the electric wire insertion direction D from the state of being attached to the terminal support portion 12.

  The jig 50 has a jig base 51 and two legs 52 (see FIG. 1). Each leg 52 is bent, for example, in an L shape. Each leg 52 is, for example, the width of a portion of the conductive portion 31 supported by the support portion 11a that protrudes from the support portion 11a onto the flat surface portion 10c (perpendicular to the direction in which the conductive portion 31 extends and the side surface portion of the groove portion 10b. (Dimensions in the direction perpendicular to 10d) are arranged in parallel to each other with a predetermined interval wider than that. Each leg portion 52 has a slope portion 53 and a tip portion 54. Each slope portion 53 gradually decreases in thickness toward the distal end portion 54. Each distal end portion 54 is inserted between the step portion 21c of the first contact leg portion 21 and the flat surface portion 10c of the groove portion 10b. Each front-end | tip part 54 is arrange | positioned at intervals wider than the width | variety of the part which protrudes on the plane part 10c from the support part 11a among the electroconductive parts 31 supported by the support part 11a. For this reason, each front-end | tip part 54 becomes insertable between the step part 21c and the plane part 10c, without interfering with the electroconductive part 31. FIG.

  Next, a procedure for connecting the electric wire 30 and the external electrode 41 will be described. FIG. 7 is a diagram schematically showing how the electric wire 30 is attached to the connector 100. FIG. 8 is a diagram schematically showing how the external substrate 40 is attached to the case. In the embodiment, as illustrated in FIGS. 7 and 8, a case where the connector 100 is attached to the case C fixed to the wall W will be described as an example. In the example shown in FIG.7 and FIG.8, through-holes Wa and Ca for drawing out the electric wire 30 to the room R side are formed in the wall W and the case C. The electric wire 30 is drawn out to the room R side through the through holes Wa and Ca. The case C is provided with an opening (not shown) at a position corresponding to the boss 16 of the connector 100.

  In this case, as shown in FIG. 7, the operator fits the boss 16 of the connector 100 into the opening of the case C. Thereby, the connector 100 is attached to a predetermined position of the case C. Next, the worker attaches the electric wire 30 to the connector 100 and connects the terminal 20 and the electric wire 30. Next, as shown in FIG. 8, the worker attaches the external substrate 40 to the case C and connects the terminal 20 and the external electrode 41.

  FIG. 9 is a diagram showing a flow of work for connecting the electric wire 30 and the external electrode 41. When the electric wire 30 is inserted into the connector 100, the conducting portion 31 is inserted between the terminal support portion 12 (and the connection portion 23) and the support portion 11a. In the embodiment, the curved surface portion 12 a is provided on the front side of the terminal support portion 12 in the electric wire insertion direction D, and the front side of the connection portion 23 in the electric wire insertion direction D is a smooth curved surface. For this reason, the conduction | electrical_connection part 31 can be inserted favorably, without inhibiting insertion property. Moreover, the coating | coated part 32 is also inserted in the support part 11b. Next, the first state (ST01 in FIG. 9) will be described. When the electric wire 30 is further inserted, the conduction portion 31 comes into contact with the first contact leg portion 21 or the tip portion 21b of the terminal 20. That is, the conduction portion 31 is sandwiched between the first contact leg portion 21 and the support portion 11a.

  The second state (ST02 in FIG. 9) will be described. Thereafter, when the operator further inserts the electric wire 30 into the connector 100, the conductive portion 31 is inserted into the back side of the electric wire mounting portion 11 while pushing up the first contact leg portion 21. The terminal 20 has a tip portion 21b of the first contact leg portion 21 and a tip portion 22b of the second contact leg portion 22 in the direction toward the outside of the base body 10 with the connection portion 23 as a center, that is, the opposite direction of FIG. It swings (turns) in conjunction with the clockwise direction. Hereinafter, the counterclockwise direction in FIG. 9 is referred to as an outer swinging direction.

  On the other hand, as the terminal 20 swings, the tip 22b of the second contact leg 22 abuts on the swing restricting portion 14, and swinging in the outer swing direction is restricted. The second contact leg 22, the connecting part 23, and the first contact leg 21 are elastically deformed as a whole by the push-up of the first contact leg 21 and the restriction of the swing of the tip 22b, and the conduction from the tip 21b. A first biasing force is applied to the portion 31. Further, since the first contact leg portion 21 is elastically deformed with the corner portion 12 b of the terminal support portion 12 as a fulcrum, a second urging force is applied to the conductive portion 31.

  By the first urging force and the second urging force applied from the terminal 20 to the conductive portion 31, the electric wire 30 is securely held by the connector 100 and is electrically connected to the terminal 20. At this time, the bent portion 22 c of the second contact leg portion 22 protrudes outward from the mounting surface 10 a of the base body 10 and is reliably disposed at a position where it can contact the external electrode 41. The tip 22b of the second contact leg 22 abuts on the swing restricting portion 14 (or biases the swing restricting portion 14) by the resultant force of the reaction force of the first biasing force and the reaction force of the second biasing force. Thus, the swinging in the outer swinging direction is restricted. That is, the second contact leg portion 22 after the insertion of the electric wire 30 is bent in a state where an urging force (the resultant force of the first urging force and the second urging force) is applied in the outward swinging direction. The part 22c protrudes from the base body 10 with a predetermined dimension. Insertion of the electric wire 30 is completed when the conducting portion 31 comes into contact with the positioning portion 15.

  After the electric wire 30 is thus inserted, the operator aligns the positions of the external electrodes 41 arranged on the external substrate 40 and the terminals 20 of the connector 100. Thereafter, as shown in FIG. 8, the worker attaches the external substrate 40 to the case C so that the external electrode 41 and the terminal 20 are in contact with each other. When the external substrate 40 is attached to the case C in the second state, the second contact leg portion 22 of the terminal 20 is brought into a third state in which it contacts the external electrode 41.

  The third state (ST03 in FIG. 9) will be described. The second contact leg portion 22 of the terminal 20 is pressed by the external electrode 41 and enters the inside of the base body 10 while being elastically deformed. At this time, a new biasing force is generated in the second contact leg portion 22, and a new reaction force (third biasing force) is generated in the first contact leg portion 21. That is, a stronger biasing force (the resultant force of the first biasing force, the second biasing force, and the third biasing force) is applied to the conductive portion 31 than in the second state. This urging force serves as a contact pressure for holding the electric wire 30 more firmly and obtaining more reliable electric conduction between the electric wire 30 and the terminal 20. The terminal 20 makes the dimension from the connection part 23 to the tip part 21b of the first contact leg part 21 shorter than the dimension from the connection part 23 to the bent part 22c of the second contact leg part 22. Thereby, the urging | biasing force to the conduction | electrical_connection part 31 can be raised more. Further, the protruding amount of the bent portion 22c from the base body 10 can be increased, and the followability (large displacement amount) with respect to the external substrate 40 can be improved.

  In the third state, the distal end portion 22 b of the second contact leg portion 22 is located on the far side in the electric wire insertion direction D with respect to the positioning portion 15. In the embodiment, the positioning portion 15 is disposed at a position where the tip portion 22b of the second contact leg portion 22 and the tip end 31a of the conductive portion 31 of the electric wire 30 are blocked in the third state. Further, a space K is formed on the back side in the electric wire insertion direction D with respect to the positioning portion 15, and it is possible to prevent the front end portion 22 b of the second contact leg portion 22 from contacting the conductive portion 31 of the electric wire 30. . Thereby, even when the displacement amount of the second contact leg portion 22 is large, the connector 100 can be lowered in height.

  Next, a procedure for removing the electric wire 30 attached to the connector 100 will be described. Removal of the electric wire 30 is performed with the connector 100 in the second state. Therefore, when the external board 40 is attached to the connector 100, the external board 40 is removed.

  FIG. 10 is a diagram illustrating a flow of work for removing the electric wire 30 from the connector 100. Hereinafter, an example in which the electric wire 30 is removed using the jig 50 will be described. A 1st extraction process (ST11 of FIG. 10) is demonstrated. In the first extraction step, the jig 50 is arranged with the two tip portions 54 facing the jig insertion portion 13.

  A 2nd extraction process (ST12 of FIG. 10) is demonstrated. When the operator inserts the jig 50 into the base body 10 in the direction opposite to the electric wire insertion direction D, the two tip portions 54 come into contact with the flat portion 10c of the groove portion 10b. When the operator further inserts the jig 50, the two distal end portions 54 move to the back side of the base body 10 so as to slide on the flat portion 10c, and the flat portion 10c and the step portion 21c of the first contact leg portion 21 are moved. Get in between. In the embodiment, the two distal end portions 54 are arranged with a gap wider than the width of the portion of the conductive portion 31 protruding from the support portion 11a onto the flat portion 10c. For this reason, the two front-end | tip parts 54 are arrange | positioned between the plane part 10c and the step part 21c, without interfering with the electroconductive part 31. FIG.

  A 3rd extraction process (ST13 of FIG. 10) is demonstrated. When the operator further pushes the jig 50 into the back side of the base body 10, the two tip portions 54 move to the back side along the flat surface portion 10 c, and the stepped portion 21 c is pushed up along the slope portion 53. At this time, the distal end portion 21 b may be separated from the conductive portion 31 by adjusting the pushing amount of the jig 50. Thereby, the force with which the first contact leg portion 21 biases the conductive portion 31 is weaker than that in the second state. That is, the force with which the first contact leg 21 holds the conductive portion 31 is smaller than that in the second state.

  A 4th extraction process (ST14 of FIG. 10) is demonstrated. In the fourth extraction step, the operator pulls the electric wire 30 toward the front side in the electric wire insertion direction D, whereby the electric wire 30 is easily extracted.

Since the leg portion 21 abuts on the conductive portion 31 and applies a biasing force to the support portion 11a side, the electric wire 30 can be held on the base 10. For this reason, the operation | work which pulls out the electric wire 30 from the wall W, the operation | work which screws the electric wire 30 to the connection part connected to the external board | substrate 40 using a tool, and returns the drawn electric wire 30 to the inside of the wall W outside. The electric wire 30 can be mounted by a simple operation without performing the operation of mounting the substrate 40 or the like. Thereby, the workability | operativity at the time of connecting the electric wire 30 can be improved, and an electric wire can be connected (a holding | maintenance and conduction | electrical_connection) easily.

  In the connector 100 according to the embodiment, the first contact leg portion 21 applies a biasing force to the conductive portion 31 of the electric wire 30 in the second state. Further, the second contact leg portion 22 protrudes to the outside of the base body 10 with a predetermined dimension in a state where an urging force is applied in the outer swinging direction, and can come into contact with the external electrode 41. Therefore, the operation of mounting the electric wire 30 on the electric wire mounting portion 11 and the operation of projecting the second contact leg portion 22 that contacts the external electrode 41 to the outside of the base body 10 can be performed in conjunction with each other. Thereby, workability | operativity can be improved in the operation | work which connects the electric wire 30 and the external electrode 41. FIG.

However, the configuration may be such that three or five or more portions are provided. The connector having such a configuration is not limited to the configuration used for the relay device, and may be used for connecting another device such as an operation terminal to an external power source.

  In the said embodiment, although the connector 100 and 200 demonstrated the case where it was the structure which extracts the electric wire 30 from the base | substrates 10 and 110 by inserting the jig | tool 50 from the jig | tool insertion part 13, it does not limit to this. Absent. FIG. 13 is a cross-sectional perspective view showing a connector 300 according to a modification. As shown in FIG. 13, the connector 300 has a protruding portion (a direction protruding in the lateral direction of the first contact leg portion 21 (a direction orthogonal to the direction in which the base portion 21 a extends and along the surface of the distal end portion 21 b)). The structure which has the jig | tool latching | locking part) 17 may be sufficient.

  The projecting portion 17 can apply a force to the first contact leg portion 21 in a direction away from the conductive portion 31 of the electric wire 30 by inserting and pushing up a general-purpose tool 60 such as a minus screwdriver from the outside to the base 310, for example. Is possible. The general-purpose tool 60 may be configured to be inserted from the jig insertion portion 13, or may be configured to be inserted from an insertion portion (not shown) provided on the side of the base 310. Thereby, the electric wire 30 can be easily removed by the general-purpose tool 60 without using the dedicated jig 50.

With this configuration, compared to the terminal 20 according to the embodiment, the bent portion 22 c has a shape protruding in a direction away from the first contact leg portion 21. For this reason, in the second state, the terminal 20 </ b> A can protrude the bent portion 22 c from the outside of the base body 10 as compared with the terminal 20 according to the embodiment.

  FIG. 15 is a diagram illustrating a terminal 20B according to a modification. A terminal 20B shown in FIG. 15 has a distal end portion 24b in which the first contact leg portion 21 is curved. With this configuration, the terminal 20B can press the conductive portion 31 against the support portion 11a while suppressing the conductive portion 31 from being damaged when the distal end portion 24b contacts the conductive portion 31.

  FIG. 16 is a diagram illustrating a terminal 20C according to a modification. As for the terminal 20C shown in FIG. 16, the 1st contact leg part 21 has the recessed part 24c in the front-end | tip part 21b. The recess 24 c is curved corresponding to the shape of the conductive portion 31 of the electric wire 30. With this configuration, the terminal 20C has a larger contact area between the tip portion 21b and the conductive portion 31 than the terminals 20 and 20A. For this reason, the terminal 20 </ b> C and the conductive portion 31 are more reliably connected.

  FIG. 17 is a diagram illustrating a terminal 20D according to a modification. The terminal 20D shown in FIG. 17 is formed so that the dimension in the width direction is the same between the width of the distal end portion 21b of the first contact leg portion 21 and the base portion 21a. With this configuration, the terminal 20 </ b> D can reliably hold the conductive portion 31 with the tip portion 21 b even when the conductive portion 31 is displaced in the width direction of the tip portion 21 b.

  FIG. 18 is a diagram illustrating a terminal 20E according to a modification. As for the terminal 20E shown in FIG. 18, the 1st contact leg part 21 has the clamping part 24e in the front-end | tip part 21b. The tip portion 21b has a cut at the center in the width direction. When the force is applied to the conductive portion 31 side, the distal end portion 21b is in a state where the cut is opened in the width direction, and the conductive portion 31 can be held. With this configuration, in the terminal 20E, the tip 21b can hold the conductive part 31 more firmly on the support part 11a.

  In the above embodiment, the case where the external substrate 40 is used for an operation terminal or a relay device has been described as an example. However, the present invention is not limited to this and may be used for other devices. Although the structure attached to the wall part of a building was mentioned as an example and demonstrated, it is not limited to this. For example, the structure where the external board | substrate 40 is attached to places other than the wall part of a building may be sufficient.

  In the above embodiment, the terminal 20 has been described by taking as an example a configuration in which the second contact leg portion 22 is disposed at a position that does not protrude outward from the mounting surface 10a of the base body 10 in the first state. It is not limited. For example, if the protrusion amount of the second contact leg portion 22 in the second state is larger than the protrusion amount of the second contact leg portion 22 in the first state, the second contact leg portion 22 in the first state. May be arranged at a position protruding outward from the mounting surface 10 a of the base body 10.

  Next, another embodiment of the connector according to the present application will be described. The configurations described below can be combined with the above configurations as appropriate. FIG. 19 is a perspective view of the connector 400 according to the present embodiment. 20 is a perspective view of the connector 400 when viewed from an angle different from that in FIG. FIG. 21 is a perspective view showing a part of the connector 400. The connector 400 includes a base body 410 and terminals 420. The base 410 has four grooves 410b on the mounting surface 410a. The base 410 has a flat portion 410c in each of the four groove portions 410b. The flat surface portion 410c is provided with a wire mounting portion 411, respectively. In this case, the flat portion 410 c is disposed on the side of the electric wire insertion direction D with respect to the electric wire mounting portion 411. The terminal 420 is attached to each of the four terminal support portions 412. The jig insertion portion 413 and the swing restriction portion 414 are provided at four locations corresponding to the terminal 420, the wire mounting portion 411, and the terminal support portion 412. The jig insertion portion 413 is provided on the end surface 410 e of the base body 410. The jig insertion part 413 penetrates from the end surface 410e to the groove part 410b. The jig insertion portion 413 is formed to have a dimension capable of inserting a jig 450 for removing the electric wire 430. In the jig insertion portion 413, the shape of the opening in the end surface 410e is a convex shape.

  In the present embodiment, the base body 410 has a flange portion 418 and an engaging protrusion 419. The flange portion 418 is disposed at a position that covers the end portion on the near side in the wire insertion direction D of the wire mounting portion 411. When the electric wire 430 is attached to the electric wire attaching portion 411, the flange portion 418 is in a state of covering a part of the electric wire 430. Therefore, for example, as shown in FIG. 21, the flange portion 418 supports the electric wire 430 from the outside when an external force is applied to the electric wire 430 attached to the electric wire attaching portion 411 and the electric wire 430 is bent or turned up. . This makes it difficult to apply a load to the terminal 420. The flange portion 418 may be configured to be integrated with the base body 410 or may be configured to be detachable from the base body 410. When the flange portion 418 is configured to be detachable from the base 410, the flange portion 418 is removed when the electric wire 430 is attached to the electric wire attachment portion 411, and the flange portion 418 is attached to the base 410 after the electric wire 430 is attached. Can be attached. Thereby, since it becomes easy to insert the electric wire 430, workability | operativity improves.

  The engaging protrusions 419 are disposed on both sides of the terminal support portion 412. The engaging protrusion 419 engages with an engaging portion 425 described later. The engaging protrusion 419 includes a protrusion 419a, an inclined portion 419b, and a step portion 419c. The protruding portion 419a is inserted into a slit portion 426 between an engaging portion 425 and a second contact leg portion 422, which will be described later. The inclined portion 419b is disposed on the surface 410s of the base body 410. The inclined portion 419b is provided such that the protruding amount gradually increases from the near side to the far side in the electric wire insertion direction D. The step part 419c is arrange | positioned at the back | inner side edge part of the electric wire insertion direction D of the inclination part 419b.

  FIG. 22 is a perspective view of the terminal 420 according to the present embodiment. FIG. 23 is a perspective view of the terminal 420 when viewed from an angle different from that in FIG. 24 is a cross-sectional view of the connector 400 taken along the plane I (see FIG. 19). As shown in FIGS. 22 and 23, the terminal 420 includes a first contact leg 421, a second contact leg 422, and a connection part 423. Hereinafter, the configuration of the terminal 420 will be described focusing on differences from the terminal 20 according to the embodiment.

  In the terminal 420, the tip end portion 421b of the first contact leg portion 421 is bent toward the wire mounting portion 411 side. The tip portion 421b is disposed on the wire mounting portion 411 as shown in FIG. A part of the tip of the tip 421b is chamfered. The shape of the chamfered portion may be a curved shape or a flat shape. Since the tip portion 421b has a chamfered portion, for example, even when the tip portion 421b comes into contact with the groove portion 410b of the wire mounting portion 411 in a state before the wire mounting, the scraping of the base 410 is suppressed.

  The terminal 420 has a convex portion 422 d facing the outside of the base 410 at the bent portion 422 c of the second contact leg portion 422. The convex portion 422d is disposed at a portion that contacts an external substrate (not shown). Since the terminal 420 is provided with the convex portion 422d, the contact pressure can be concentrated on the convex portion 422d. Thereby, contact reliability can be improved. One convex portion 422d may be disposed, or a plurality of convex portions 422d may be disposed.

  The terminal 420 has an extending part 424 and an engaging part 425. The extending part 424 is provided at the tip part 421b of the first contact leg part 421. For example, the extending portion 424 is provided on both sides of the first contact leg portion 421, but is not limited thereto, and may be disposed on one side of the first contact leg portion 421. The extension portion 424 may be formed so that the dimension in the width direction is narrower than the width of the tip portion 421b, may be formed wider than the width of the tip portion 421b, or may be the same width.

  The extension part 424 extends to the electric wire insertion direction D side. The extension part 424 is arrange | positioned on the plane part 410c, as shown in FIG. The extension part 424 warps, for example, the second contact leg part 422 side. The tip of the extension part 424 is separated from the flat part 410c. For this reason, when viewed from the back side in the electric wire insertion direction D, a gap is formed between the tip of the extension portion 424 and the flat portion 410c.

  Moreover, the extension part 424 is arrange | positioned on the plane part 410c. In this configuration, for example, when a force on the side of the electric wire attachment portion 411 is applied to the terminal 420 in a state before the electric wire is attached, the extension portion 424 is brought into contact with the flat portion 410c. For this reason, the force applied to the terminal 420 can be supported by the extending portion 424. Therefore, it can suppress that the front-end | tip part 421b of the 1st contact leg part 421 is pressed on the electric wire mounting part 411 side, and deform | transforms.

  The engaging portion 425 is provided so as to protrude from both sides of the second contact leg portion 422. The engaging portion 425 extends from the back side in the electric wire insertion direction D toward the front side. The engaging part 425 forms a slit part 426 between the second contact leg part 422. The slit portion 426 is formed linearly from the near side in the electric wire insertion direction D to the far side. By providing the slit portion 426, the engaging portion 425 can be elastically deformed as a cantilever spring with respect to the second contact leg portion 422. The engaging portion 425 is formed elongated along the electric wire insertion direction D.

  The terminal 420 is inserted into the back side of the electric wire insertion direction D along the groove 410b with the first contact leg portion 421 and the second contact leg portion 422 facing the back side of the electric wire insertion direction D. It is supported by the support part 412. When the terminal 420 is inserted, the engaging portion 425 rides on the inclined portion 419b and exceeds the step portion 419c. The engaging portion 425 is elastically deformed when riding on the inclined portion 419b. The engaging portion 425 is restored from the elastically deformed state after exceeding the stepped portion 419c. The terminal 420 that has climbed over the stepped portion 419c is in a state in which the protruding portion 419a is inserted into the slit portion 426 between the engaging portion 425 and the second contact leg portion 422. Thereby, the engaging part 425 engages with the engaging protrusion part 419. In this case, it contributes to preventing the terminal 420 from coming off to the near side in the electric wire insertion direction D. Further, since the engaging portion 425 is formed in an elongated shape along the electric wire insertion direction D, for example, even when the terminal 420 swings when the electric wire is inserted, the engaged state with the protruding portion 419a is maintained. .

  Next, a procedure for removing the electric wire 430 attached to the connector 400 will be described. 25 and 26 are cross-sectional views showing a flow of work for removing the electric wire 430 from the connector 400. FIG. 25 and 26 show cross sections when the connector 400 is cut along the plane I (see FIG. 19). Hereinafter, an example in which the electric wire 430 is removed using the jig 450 will be described. A 1st extraction process (ST41 of FIG. 25) is demonstrated. In the first extraction step, the jig 450 is, for example, a minus driver. In the first removal step, the jig 450 is arranged with the tip 451 facing the jig insertion portion 413.

  A 2nd extraction process (ST42 of FIG. 25) is demonstrated. When the operator inserts the jig 450 into the base 410 in the direction opposite to the electric wire insertion direction D, the tip 451 contacts the flat portion 10c of the groove portion 410b. When the operator further inserts the jig 450, the tip 451 moves to the back side of the base 410 so as to slide on the flat portion 410c, and enters between the flat portion 410c and the extending portion 424. In the embodiment, the extending part 424 is separated from the flat part 410c and has a shape warped to the second contact leg part 422 side. For this reason, the tip 451 is easily inserted between the flat portion 410 c and the extending portion 424.

  A 3rd extraction process (ST43 of FIG. 26) is demonstrated. When the operator further pushes the jig 450 into the back side of the base body 410, the tip 451 moves to the back side along the flat portion 410 c, and the extending part 424 is pushed up by the tip 451. Thereby, the force with which the first contact leg portion 421 biases the conductive portion 431 is reduced. Moreover, since the shape of the opening part in the end surface 410e is convex shape among the jig | tool insertion parts 413, the attitude | position after jig | tool insertion can be stabilized by arrange | positioning the jig | tool 450 on both sides of an opening part. It becomes possible.

  A 4th extraction process (ST44 of FIG. 26) is demonstrated. In the fourth extraction step, the operator pulls the electric wire 430 toward the front side in the electric wire insertion direction D, whereby the electric wire 430 is easily extracted.

  As described above, in the connector 400 according to the embodiment, the terminal 420 has the extended portion 424 extending in the electric wire insertion direction D side in the first contact leg portion 421, so that the jig is used when the electric wire 430 is removed. 450 becomes easy to dive in the gap between the terminal 420 and the flat portion 410c, and the removal work becomes easy.

  In the connector 400 according to the embodiment, the base body 410 has a flat surface portion 410c on the side in the electric wire insertion direction D with respect to the electric wire mounting portion 411, and the electric wire mounting portion 411 is formed in a concave shape with respect to the flat surface portion 410c. In the terminal 420, the tip 421b of the first contact leg 421 is disposed on the wire mounting portion 411, and the extending portion 424 is disposed on the flat portion 410c. When a force on the electric wire mounting portion 411 side is applied, the force applied to the terminal 420 can be supported by the extending portion 424. Therefore, it can suppress that the front-end | tip part 421b of the 1st contact leg part 421 is pressed on the electric wire mounting part 411 side, and deform | transforms.

  In the connector 400 according to the embodiment, since the extension part 424 is provided on both sides of the first contact leg part 421, the extension part 424 comes into contact with both sides of the wire mounting part 411 when arranged on the flat part 410 c. For this reason, the force applied to the terminal 420 can be uniformly supported in the width direction by the extending portion 424.

  In the connector 400 according to the embodiment, since the tip of the extension part 424 is separated from the flat part 410c, a jig 450 such as a flat-blade screwdriver is inserted into the gap between the flat part 410c and the extension part 424. It becomes possible.

  In the connector 400 according to the embodiment, the terminal 420 has an engaging portion 425 protruding on both sides of the second contact leg portion 422, and the base 410 has an engaging protrusion 419 that engages with the engaging portion 425. Therefore, when the engaging portion 425 engages with the engaging protrusion 419, the positional deviation of the terminal 420 toward the front side in the electric wire insertion direction D is restricted.

  In the connector 400 according to the embodiment, the base body 410 includes a flange portion 418 that is disposed at a position that covers the end portion on the near side in the wire insertion direction D of the wire mounting portion 411. For this reason, when an external force is applied to the electric wire 430 attached to the electric wire attachment portion 411 and the electric wire 430 is bent or turned up, the electric wire 430 is supported by the flange portion 418. Thereby, it becomes difficult to apply a load to the first contact leg 421.
