Abstract

<P>PROBLEM TO BE SOLVED: To provide a quick connection terminal device wherein it is not required to lock a locking part to a part to be locked by operating a release lever again after releasing connection of a wire. <P>SOLUTION: Even if the release lever 30 is operated and the locking part 43 abuts on a conductor 201, support members 41, 41 supporting the locking part 43 bends in a direction to shrink the distance from them to regulating ribs 33, 33 (leftward in the figure 5), and the release lever 30 thereby never be raised along the conductor 201. As a result, since the locking part 43 returns to the initial position by being automatically locked to the part to be locked 12c after the wire 200 is pulled out, it is not required to lock the locking part 43 to the part to be locked 12c by operating the release lever 30 again after releasing the connection of the wire 200 as in the conventional example, and connection work of the wire can be simplified. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a quick connection terminal device.

  2. Description of the Related Art Conventionally, in a wiring device such as a switch or an outlet, a quick connection terminal device is widely used to connect an electric wire introduced into a container through an electric wire insertion hole provided in the container. This type of quick connection terminal device is well known in the art, and the electric wire (conductor) is sandwiched between the terminal plate and the terminal plate electrically connected to the contact of the switch or the blade holder of the outlet, etc. A lock spring that electrically connects the terminal plate and locks the electric wire at the same time, and a release button that releases the lock by the lock spring operated by a tool such as a driver through an operation hole provided in the body. It consists of

  However, since the above-mentioned conventional quick connection terminal device does not know from the outside whether or not the electric wire is securely connected, there is a problem of giving anxiety to the installer and a tool is required for operating the release button. Therefore, there is a problem that the work of removing the electric wires is troublesome.

  On the other hand, the applicant of the present invention has disclosed a quick-connect terminal device in which a lock by a lock spring is released with a release lever that can be operated manually without using a tool, and a wire connection completion display is performed with the release lever. It has already been proposed (see, for example, Patent Document 1).

  As shown in FIG. 8, the conventional example includes a terminal plate 10, a lock spring 20, and a release lever 30. The terminal plate 10 includes a strip-shaped main piece 11, a pair of contact pieces 12 that are hung backward from one edge along the longitudinal direction of the main piece 11, and the other of the other along the longitudinal direction of the main piece 11. The main piece 11, the contact piece 12, and the contact piece 13 are integrally formed by processing an elastic band-shaped metal plate. The contact piece 12 has a pair of pressing portions 12a and 12b that press the electric wire at both ends along the insertion direction of the electric wire (vertical direction in FIG. 8), and a direction in which the tip of the upper pressing portion 12b is separated from the contact piece 13 And a locked portion 12c that is bent and raised, and a wire between the pressing portion 12b and the main piece 11 faces the wire insertion hole 101 penetrating the bottom wall of the container body 100 of the wiring device. The insertion part 14 into which is inserted is formed.

  The lock spring 20 is formed by bending a belt-shaped metal plate having elasticity into a substantially J shape, and has a bowl-shaped conductive piece 21 that contacts the main piece 11 and the contact piece 13 of the terminal plate 10, and a conductive piece 21. The tip of the spring piece 22 that has a spring piece 22 bent in a substantially U shape from the lower end of the wire and abuts against the electric wire to prevent it from coming off becomes a locking part. The lock spring 20 is disposed inside the terminal plate 10 in such a manner that the conducting piece 21 is brought into contact with the main piece 11 and the contact piece 13 and the spring piece 22 is opposed to the contact piece 12. And the electric wire inserted from the electric wire insertion hole 101 is clamped between the contact piece 12 of the terminal board 10 and the spring piece 22 of the lock spring 20, and the locking part (the tip of the spring piece 22) is brought into contact with the electric wire. Can be prevented.

  The release lever 30 is made of a synthetic resin molded product, has a rod-like operation portion 31, a rectangular plate-like engagement portion 32 that is disposed substantially parallel to the operation portion 31, and the length of the operation portion 31 and the engagement portion 32. Connecting portions 33, 33 that connect both ends in the direction, arm portions 34, 34 that protrude laterally from the connecting portions 33, 33, and shaft portions 35, 35 that protrude inward from the tip portions of the arm portions 34, 34. And the projection parts 36 and 36 which protrude from the position near the center of shaft part 35 and 35 front end surface are integrally formed.

  In the conventional example configured as described above, when the electric wire 200 is not connected, the locking portion 32 is locked (latched) to the locked portion 12c of the terminal board 10 as shown in FIG. The release lever 30 is rotated to the rotation position (hereinafter referred to as “initial position”). When the release lever 30 is in the initial position, both ends of the spring piece 22 of the lock spring 20 are pushed by the pair of pushing portions 36, 36, and the lock portion (the tip of the spring piece 22) is separated from the contact piece 12. It is in a state of bending in the direction. At this time, the release lever 30 is elastically biased in the counter-operation direction (counterclockwise in FIG. 8) by the spring force of the spring piece 22, but the locking portion 32 is locked to the locked portion 12 c of the terminal plate 10. Therefore, the release lever 30 is held at the initial position.

  Then, when the conductor 201 of the electric wire 200 is introduced between the contact piece 12 and the spring piece 22 through the electric wire insertion hole 101, the tip of the conductor 201 comes into contact with the engaging portion 32 of the release lever 30 through the insertion portion 14, The part 32 is pushed up to release the latched state of the locking part 32 and the locked part 12c. Then, the release lever 30 that is elastically biased by the spring force of the spring piece 22 rotates in the counter-operation direction, and the lock portion at the tip of the spring piece 22 comes into contact with the conductor 201 to prevent the electric wire 200 from coming off. At the same time, the conductor 201 elastically contacts the contact piece 12 by the spring force of the spring piece 22. Furthermore, the conductor 201 is pressed toward the spring piece 22 by the pair of pressing portions 12a and 12b, and the pressing force of the locking portion and the pair of pressing portions 12a and 12b is balanced to hold the electric wire 200.

  On the other hand, if the operation part 31 is pushed upward while the electric wire 200 is connected, the release lever 30 rotates in the opposite direction (clockwise in FIG. 8) with the shaft parts 35 and 35 as fulcrums. The spring pieces 22 are bent so that the locking portions 33 and 33 press the spring pieces 22 of the lock spring 20 and the lock portions (tips of the spring pieces 22) that are in contact with the conductor 201 are separated from the conductor 201. Therefore, the electric wire 200 can be pulled out.

Thus, in the above conventional example, when the connection with the electric wire 200 is completed, the operation part 31 of the release lever 30 moves to a position below the initial position, so that the completion of the connection of the electric wire can be displayed. An increase in the number of parts can be suppressed by using the release lever 30 for releasing the connection of 200 as a connection completion display of the electric wire 200.
JP 2006-12634 A

  However, in the above conventional example, when the release lever 30 is operated to release the connection of the electric wire 200, the locking portion 32 comes into contact with the conductor 201 of the electric wire 200 as shown in FIG. Rises along the conductor 201, and after the electric wire 200 is pulled out, the locking portion 32 cannot be locked to the locked portion 12c, and the release lever 30 becomes completely free (FIG. 8B). reference). Therefore, in order to connect the electric wire 200 again, it is necessary to operate the release lever 30 to lock the locking portion 32 to the locked portion 12c and return to the initial position (see FIG. 8C). .

  The present invention has been made in view of the above circumstances, and the purpose of the present invention is to achieve quick connection that does not require the locking portion to be locked to the locked portion by operating the release lever again after releasing the connection of the electric wire.

  As shown in FIGS. 1 to 5, the quick connection terminal device of the present embodiment includes a terminal plate 10, a lock spring 20, and a release lever 30.

  The terminal plate 10 includes a strip-shaped main piece 11, a pair of contact pieces 12 that are hung backward from one edge along the longitudinal direction of the main piece 11, and the other of the other along the longitudinal direction of the main piece 11. The main piece 11, the contact piece 12, and the contact piece 13 are integrally formed by processing an elastic band-shaped metal plate. In addition, when the quick connection terminal device of this embodiment is provided in an outlet, a blade receiver is formed integrally with the terminal plate 10, and when provided in a switch, a contact is formed integrally with the terminal plate 10. In the present embodiment, configurations relating to wiring devices such as outlets and switches are omitted. The contact piece 12 has a pair of pressing portions 12a and 12b that press the electric wire at both ends along the insertion direction of the electric wire (vertical direction in FIG. 1), and a direction that leaves the tip of the upper pressing portion 12b away from the contact piece 13. The insertion portion 14 is formed between the pressing portion 12b and the main piece 11 so as to face an electric wire insertion hole 101 described later and through which the electric wire is inserted.

  The lock spring 20 is formed by bending a belt-shaped metal plate having elasticity into a substantially J shape, and has a bowl-shaped conductive piece 21 that contacts the main piece 11 and the contact piece 13 of the terminal plate 10, and a conductive piece 21. The tip of the spring piece 22 that has a spring piece 22 bent in a substantially U shape from the lower end of the wire and abuts against the electric wire to prevent it from coming off becomes a locking part. Further, the spring piece 22 is provided with a bent portion 22a that protrudes in a direction away from the electric wire (a direction approaching the conductive piece 21). As shown in FIG. 5, the lock spring 20 is arranged inside the terminal plate 10 such that the conducting piece 21 is brought into contact with the main piece 11 and the contact piece 13 and the spring piece 22 is opposed to the contact piece 12. . Here, the width dimension of the contact piece 12 is narrower than the width dimension of the spring piece 22, and the spring pieces 22 are formed on both sides of the contact piece 12 when viewed from the direction perpendicular to the insertion direction of the electric wire (left and right direction in FIG. 1). Has come to protrude. The terminal plate 10 and the lock spring 20 configured as described above are stored in a terminal plate storage chamber 102 provided in a body 100a that constitutes a body 100 of a wiring device such as a switch or an outlet as shown in FIG. A pair of electric wire insertion holes 101 are formed through the bottom wall of the terminal plate storage chamber 102.

  The release lever 30 includes a lever body made of a synthetic resin molded product and a metal plate block that is insert-molded in the lever body. As shown in FIGS. 1 and 3, the lever body includes a rod-shaped operation portion 31, a pair of restriction ribs 33, 33 protruding forward (upward in FIG. 1) from both longitudinal ends of the operation portion 31, and a restriction rib 33. 33, a pair of arm portions 34, 34 projecting laterally from each other, a pair of shaft portions 35, 35 projecting inwardly from the tip portions of the arm portions 34, 34, and the shaft portions 35, 35 near the center of the tip surface A pair of protruding pusher portions 36 and 36 projecting from the positions of the two and a connecting portion 37 disposed in parallel with the operation portion 31 so as to connect the pair of pusher portions 36 and 36 are integrally formed. Has been. The metal plate block is formed by integrally forming a locking piece 40, a support member 41, and an auxiliary spring 42 by bending an elastic strip-shaped metal plate. The locking piece 40 and the support members 41 and 41 that support the locking piece 40 are formed in a substantially U shape, and are engaged at the distal ends of the support members 41 and 41 that protrude from both arm portions 34 and 34 of the lever body. Both ends of the stop piece 40 are supported. The locking piece 40 is arranged in parallel with the operation portion 31 at a slight distance from the tip portions of the regulating ribs 33, 33, and has a rectangular parallelepiped-shaped locking portion 43 made of a synthetic resin molded product at the center in the longitudinal direction. Is integrally molded. Further, the support member 41 is curved so as to approach the regulating ribs 33 and 33 of the lever body, and is disposed along the regulating ribs 33 and 33 (see FIG. 3A). Here, the central portion in the longitudinal direction of the locking piece 40 is normally locked (latched) to the locked portion 12 c of the terminal board 10, but compared to the locking piece 40 and the support members 41, 41. By providing the locking part 43 having a large width and thickness, there is an advantage that the locking with the locked part 12c can be easily performed. The auxiliary spring 42 is substantially bowl-shaped and protrudes from the front end surface of the pressing portion 36 on one side and is arranged substantially parallel to the regulating rib 33. However, a reinforcing projection 36 a that reinforces the base portion of the auxiliary spring 42 is provided in the push portion 36.

  Here, in this embodiment, two each of the quick connection terminal devices are provided for each terminal plate 10 including those for the feed wiring, and these two quick connection terminal devices together with each terminal plate 10 and the lock spring 20 are provided in the body. 100a is housed side by side in the terminal board storage chambers 102, 102 provided on both sides in the longitudinal direction of 100a. A plurality of vertical grooves 104 communicating with the terminal plate storage chamber 102 are provided on the side surface of the body 100 a, and the regulating ribs 33 and 33 and the operation unit 31 are disposed outside the container body 100 through a pair of adjacent vertical grooves 104 and 104. The release lever 30 is attached to the body 100a in the disposed state (see FIG. 2). A pair of supporting ribs (not shown) for supporting the shaft portions 35, 35 when the release lever 30 is rotated are located between the pair of vertical grooves 104, 104 and the wire insertion hole 101 in the body 100 a. Is provided. Note that, in the state of being stored in the terminal plate storage chamber 102, the distal end portion of the auxiliary spring 42 is in contact with the contact piece 13 of the terminal plate 10.

  In the quick connection terminal device of the present embodiment configured as described above, when the electric wire 200 is not connected, the locking portion 43 is the locked portion of the terminal plate 10 as shown in FIG. The release lever 30 is rotated to a rotation position that is latched with 12c (hereinafter, this rotation position is referred to as an “initial position”). When the release lever 30 is in the initial position, both ends of the spring piece 22 of the lock spring 20 are pushed by the pair of pushing portions 36, 36, and the lock portion (the tip of the spring piece 22) is separated from the contact piece 12. It is in a state of bending in the direction. At this time, the auxiliary spring 42 whose tip is in contact with the contact piece 13 is bent, and the release lever 30 is moved in the counter-operation direction (by the return force (spring force) of the auxiliary spring 42 and the spring force of the spring piece 22). The release lever 30 is held in the initial position because the locking portion 43 is locked to the locked portion 12c of the terminal board 10, although it is elastically biased in the counterclockwise direction in FIG. become.

  When the conductor 201 of the electric wire 200 is introduced between the contact piece 12 and the spring piece 22 through the electric wire insertion hole 101, the tip of the conductor 201 is engaged with the release lever 30 through the insertion portion 14 as shown in FIG. It abuts on the stop portion 43 and pushes up the lock portion 43 to release the latched state of the lock portion 43 and the locked portion 12c. Then, the release lever 30 that is elastically biased by the spring force of the spring piece 22 and the auxiliary spring 42 rotates in the counter-operation direction, and the lock portion at the tip of the spring piece 22 contacts the conductor 201, whereby the electric wire 200 is connected. The conductor 201 is elastically contacted with the contact piece 12 by the spring force of the spring piece 22 while being prevented from coming off. Furthermore, the conductor 201 is pressed toward the spring piece 22 by the pair of pressing portions 12a and 12b, and the pressing force of the locking portion and the pair of pressing portions 12a and 12b is balanced to hold the electric wire 200. That is, when the connection between the terminal board 10 and the electric wire 200 is completed, the operation part 31 of the release lever 30 moves to a position below the initial position, whereby the electric wire connection completion display can be visually confirmed.

  On the other hand, as shown in FIG. 5 (d), if the operation unit 31 is operated to be pushed up with the electric wire 200 connected, the release lever with the shaft portions 35, 35 supported by the support ribs as fulcrums. 30 is rotated in a direction opposite to that at the time of connection (clockwise direction in FIG. 5), and the locking portions 33, 33 press the spring pieces 22 of the lock spring 20 to contact the conductor 201 ( The electric wire 200 can be pulled out by bending the spring piece 22 so that the tip of the spring piece 22 is separated from the conductor 201. Here, in the conventional example, when the release lever 30 is operated to release the connection of the electric wire 200, the locking portion 43 comes into contact with the conductor 201 of the electric wire 200 as shown in FIG. Since the locking portion 43 cannot be locked to the locked portion 12c after the electric wire 200 is pulled out along the conductor 201, the release lever 30 becomes completely free. In order to do this, it is necessary to operate the release lever 30 to lock the locking portion 43 to the locked portion 12c and return to the initial position.

  On the other hand, in this embodiment, even if the release lever 30 is operated and the locking portion 43 comes into contact with the conductor 201, the support members 41 and 41 supporting the locking portion 43 are connected to the regulating ribs 33 and 33. The release lever 30 does not rise along the conductor 201 by bending in the direction of reducing the distance (leftward in FIG. 5). As a result, since the locking portion 43 is automatically locked to the locked portion 12c after the electric wire 200 is pulled out and returns to the initial position, the release lever is released again after releasing the connection of the electric wire 200 as in the conventional example. It is not necessary to operate 30 to lock the locking portion 43 to the locked portion 12c, and the wire connection work can be simplified. In addition, the regulation ribs 33 and 33 are arrange | positioned at the tip of the direction in which the supporting members 41 and 41 bend, respectively, and it is not necessary for the supporting members 41 and 41 to bend more than necessary (for example, the extent which plastically deforms). It can be prevented by being regulated by the regulation ribs 33, 33. Further, when there is no restriction rib 33, 33, the terminal plate 10 accommodated in the terminal plate storage chamber 102 through the vertical groove 104 on the side surface of the container 100 can be seen from the outside. However, as shown in FIG. Since the vertical groove 104 is blinded by 33 and 33, the terminal board 10 is not visible from the outside. Further, as shown in FIG. 6A, if the tip portions of the pair of regulating ribs 33, 33 are extended to the vicinity of the locking portion 43, the regulating ribs 33, 33 are released from the release lever 30 at a position near the locking portion 43. The plastic deformation of the support members 41 and 41 can be more reliably prevented by abutting against. Furthermore, as shown in FIG. 6B, if the tip portions of the pair of regulating ribs 33, 33 are connected in the vicinity of the locking portion 43, there is an advantage that the strength of the regulating ribs 33, 33 can be increased. .

  Here, the reason why the auxiliary spring 42 is provided in the present embodiment will be described. When the connection of the electric wire 200 is completed as described above, the engagement between the locking portion 43 and the locked portion 12c is released and the release lever 30 rotates in the counter-operation direction, but the electric wire 200 is connected. In this state, the spring piece 22 of the lock spring 20 does not come into contact with the pushing portions 36, 36. Therefore, when the container body 100 is held with the bottom surface where the wire insertion hole 101 opens vertically upward, the auxiliary spring 42 is If not, the release lever 30 moves in the operation direction due to its own weight, and the connection completion display may become unclear. On the other hand, if the release lever 30 is always elastically biased in the counter-operation direction by the auxiliary spring 42, the locking portion 43 and the locked portion 12c are unlocked even when held as described above. The release lever 30 is prevented from moving in the operation direction by its own weight, and the completion of connection can be reliably displayed.

  By the way, in this embodiment, the release lever 30 is comprised by the lever main body which consists of a synthetic resin molded article, the latching piece 40 formed with the metal material, and the support members 41 and 41, For example, resin material with large elasticity The locking piece 40 ′ and the support members 41 ′ and 41 ′ may be formed by resin molding integrally with the lever body (see FIG. 7A). Alternatively, if the elasticity required for the locking piece and the support member and the strength required for the lever body cannot be compatible with one type of resin material, the release lever 30 is configured by two-color molding using a resin material suitable for each. You may do (refer FIG.7 (b)). Further, instead of insert-molding the locking piece 40 and the support members 41 and 41 into the lever body, the locking piece 40 and the metal body 44 formed integrally with the support members 41 and 41 are press-fitted and fixed to the lever body. (See FIG. 7C), or the metal body 44 can be joined to the lever body by an appropriate method such as adhesion or welding (see FIG. 7D).
