  As a preferred embodiment, a pair of retaining portions that contact the rod-shaped conductor connector and prevent the rod-shaped conductor from coming out of the rod-shaped conductor connector in the length direction are the rod-shaped conductor. The aspect provided in (1) is illustrated.

It is a principal part front view of the connection structure of the rod-shaped conductor which concerns on one Embodiment of this invention. It is a side view of FIG. FIG. 2 is an exploded perspective view of FIG. 1. It is a front view which shows the other example of a locking member. It is a front view of the connector which concerns on other embodiment.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIGS. 1-3, the connection structure of the rod-shaped conductor which concerns on one Embodiment of this invention is the rod-shaped conductor which concerns on the connection object 2 of the rod-shaped conductor 1 according to one Embodiment of this invention. When the connector 3 is fixed and the rod-shaped conductor 1 is sandwiched between the pair of arm portions 4 and 4 of the connector 3, the rod-shaped conductor 1 is electrically connected to the connection object 2. It is a structure to be. The rod-shaped conductor 1 is made of a metal material having good conductivity such as copper or aluminum.

  Although only the end 1a is shown in the figure, the rod-like conductor 1 is wired (arranged) in a controller such as an inverter to electrically connect electronic or electrical devices. The rod-shaped conductor 1 is wired by appropriately providing a bent portion according to the wiring environment. In the illustrated example, the rod-shaped conductor 1 is illustrated as a round bar-shaped conductor having a circular cross section, but is not necessarily limited to a round bar, and can be implemented even in the shape of a square bar. However, in that case, the shape of the pair of arm portions 4 and 4 is changed so as to securely hold the rod-shaped conductor in accordance with the shape of the peripheral surface of the rod-shaped conductor.

  The connector 3 includes a base portion 5 and a pair of arm portions 4 and 4, and is entirely formed of a metal material having good conductivity. The base portion 5 has an attachment surface 5 a to the connection target 2 of the rod-shaped conductor 1. An appropriate number of wiring legs 6 are integrally provided on the mounting surface 5a.

  In the connector 3, the mounting surface 5 a is fixed to a connection object 2 (a connection partner) of the rod-shaped conductor 1 by a method such as soldering. On the connection target side, a hole 7 for receiving the wiring leg 6 of the connector 3 is formed. By fixing the connector 3 to the connection target 2, the wiring leg 6 is connected to the connection target 2 side. It connects with the electric wire 8 wired beforehand.

  The pair of arm portions 4, 4 sandwich the end portion 1 a of the rod-shaped conductor 1 on the base portion 5. The pair of arm portions 4, 4 are formed to have elasticity by, for example, giving a predetermined shape to a leaf spring, and the rod-shaped conductor 1 is formed by elastic deformation of the pair of arm portions 4, 4. Hold it. In the illustrated example in which the rod-shaped conductor 1 is a round bar, each arm portion 4 includes a curved surface 4 a corresponding to the peripheral surface of the rod-shaped conductor 1 so that the rod-shaped conductor 1 can be easily held. When the rod-shaped conductor 1 has a shape other than a round bar, the curved portion is changed to another shape according to the shape of the peripheral surface. The tip (upper end) side of the pair of arm portions 4 and 4 is open in an inverted C shape. This is to make it easier to guide the rod-shaped conductor 1 between the pair of arm portions 4 and 4.

  The pair of arm portions 4, 4 are pushed open by pressing the peripheral surface of the rod-shaped conductor 1 against the opening 9 on the distal end side of the pair of arm portions 4, 4. By further pressing downward, the rod-shaped conductor 1 reaches between the curved surfaces 4a, 4a, and the rod-shaped conductor 1 is securely held by the elastic deformability of the pair of arm portions 4, 4. By holding the rod-shaped conductor 1 between the pair of arm portions 4, 4, the rod-shaped conductor 1 and the connector 3 are electrically connected.

  If the connector 3 is used, in order to connect the rod-shaped conductor 1 to the connection object 2, it is necessary to provide a flat plate-like connection portion with a mounting hole at the end of the rod-shaped conductor, which was conventionally required. Absent. For this reason, the cost for the connection of the rod-shaped conductor 1 is suppressed. Further, since the connection work is completed simply by holding the end 1a of the rod-shaped conductor 1 between the pair of arm parts 4 and 4, the connection work is simple and can be performed quickly. When necessary, for example, when the rod-shaped conductor 1 is replaced, the rod-shaped conductor 1 can be easily detached from the connector 3 by pulling the rod-shaped conductor 1 upward from the connector 3 in a horizontal state.

  In addition, as shown in FIG. 2, it is preferable to form a pair of retaining portions 10 and 10 at the end 1a of the rod-shaped conductor 1 in advance. The pair of retaining portions 10, 10 are separated in the length direction of the rod-shaped conductor 1, and the length of the rod-shaped conductor 1 from the connector 3 is brought into contact with the pair of arm portions 4, 4. Prevents slipping out in the vertical direction. The pair of retaining portions 10, 10 can be formed by partially pressurizing and deforming the peripheral surface of the rod-shaped conductor 1.

  Since the rod-shaped conductor 1 is securely clamped by the elastic deformation of the pair of arm portions 4, 4, the rod-shaped conductor 1 does not escape upward from the distal end side openings 9 of the pair of arm portions 4, 4. However, a lock member can also be provided in order to more reliably prevent upward slipping. This locking member prevents the end portion 1a of the rod-shaped conductor 1 from being detached from the distal end side opening 9 of the pair of arm portions 4, 4 from the state of being sandwiched between the pair of arm portions 4, 4. To do.

  As an example of the locking member, a bifurcated clip 11 can be employed as shown in FIG. The bifurcated clip 11 is engaged with a pair of lock grooves 12, 12 on the distal end side of the pair of arm portions 4, 4. That is, in the pair of arm portions 4, 4, a groove is formed on the outer surface of the arm 4 by providing the distal end side opening 9 in an inverted C shape on the curved portions 4 a, 4 a. . Using this groove as the lock groove 12, the bifurcated clip 11 is mounted.

  The bifurcated clip 11 in FIG. 3 is formed into a bifurcated shape by bending a wire made of spring steel, and a reverse C-shaped guide portion 13 for facilitating the mounting to the connector 3 is provided at the tip portion. In front of the guide portion 13, a stop portion 14 is provided for retaining. After the rod-shaped conductor 1 is sandwiched between the pair of arm portions 4, 4, the bifurcated clip 11 is attached to the lock grooves 12, 12 of the pair of arm portions 4, 4, thereby the pair of arm portions Since the opening of the leading end side openings 4 and 4 is prevented, the rod-shaped conductor 1 cannot be pulled out upward.

  The bifurcated clip 11 is easy to remove. Therefore, when necessary, for example, when the rod-shaped conductor 1 is replaced, the bar-shaped conductor 1 is removed by removing the bifurcated clip 11 from the connector 3. It can be removed from the connector 3.

  As another example of the lock member, as shown in FIG. 4, a rotation lock piece 15 can be adopted. One end of the rotation lock piece 15 is pivotally supported on one side of the pair of arm portions 4, 4 by a shaft 17, and extends so as to cover the opening on the front end side of the pair of arm portions 4, 4. The other end is locked to the other arm side. The rotation lock piece 15 is produced using, for example, spring plate steel or the like, and the locking portion 16 on the other end side is hooked on the upper end portion of the arm portion 4 by the elasticity of the rotation lock piece 15. Also in this case, after the rod-shaped conductor 1 is sandwiched between the pair of arm portions 4, 4, the tip side opening 9 of the pair of arm portions 4, 4 is closed by the rotation lock piece 15, Since the opening of the distal end side opening 9 of the pair of arms 4 and 4 is prevented, the rod-shaped conductor 1 cannot be pulled out upward.

  The above embodiment is a mode in which the pair of arm portions 4 and 4 sandwich the rod-like conductor by elasticity, but it is not essential that the pair of arm portions 4 and 4 have elasticity. As another embodiment, the mode shown in FIG. 5 can also be implemented.

  The rod-shaped conductor connector 18 of FIG. 5 is pivotally supported by a fixed arm 19 on the base portion 5 side and a shaft 20 on the base portion 5 side as elements corresponding to the pair of arm portions 4 and 4. A rotating arm 21 that extends to cover the fixed arm 19 and is locked to the base portion 5 side. The shapes of the fixed arm 19 and the rotating arm 21 correspond to the peripheral shape of the rod-shaped conductor 1. When the rod-shaped conductor 1 is a round bar, the fixed arm 19 and the rotating arm 21 are both formed in a semicircular shape.

  One end 21 a of the rotating arm 21 is pivotally supported by one end 19 a of the fixed arm 19, and the other end 21 b side of the rotating arm 21 can be rotated up and down on the fixed arm 19. A lock member is provided between the rotating arm 21 and the fixed arm 19 to hold them in a fixed state. In the example of FIG. 5, a well-known toggle latch 22 is employed as the locking member. By hooking a loop-shaped latch 23 of the toggle latch 22 disposed on the rotating arm 21 side to the hook 19b at the other end of the fixed arm 19, the operation piece 24 of the toggle latch 22 is rotated to the locked state. The rotating arm 21 is fixed to the fixed arm 19.

  By arranging the rod-shaped conductor 1 on the fixed arm 19, covering the rod-shaped conductor with the rotating arm 21 and fixing with the toggle latch 22, the rod-shaped conductor 1 can be easily connected to the connector 18. The By unlocking the toggle latch 22, the rod-shaped conductor 1 can be easily removed.

  In the connector 18 of FIG. 5, the base portion 5 is the same as the example of FIG.

  Of course, the rod-like conductor 1 can be electrically connected to the connection object 2 at a place other than the end using the connectors 3 and 18.
