Yes. The U-slit terminal 11 is integrally formed with a terminal piece body 13 in which three U-shaped portions are continuously provided. The clamp terminal 12 includes a deformed S-shaped three-piece spring plate that is separately formed and press-fitted into the three U-shaped portions of the terminal piece body 13.

  As shown in detail in FIGS. 1 and 5, the connector block 2 includes an elongated box-shaped casing 21, a plate-shaped bottom plate 22 that completely blocks the bottom of the casing 21, and a top portion of the casing 21. It consists of a small block type operation block 23 that is partially closed. The casing 21 is partitioned into two chambers by a partition wall 21a parallel to the longitudinal side, and a locking groove 21b for locking the bottom plate 22 is provided in the vicinity of the edge on the long side of the bottom, and the upper and lower sides on the short side of the side are provided. Locking protrusions 21c for locking to the connector base 3 are provided on the side, and a window 21d into which the operation block 23 is fitted is opened at the top. The bottom plate 22 is provided with a locking projection 22a corresponding to the locking groove 21b of the casing 21 on the edge on the long side, and a slit 22b through which the U-slit terminal 11 of the terminal piece 1 is inserted is opened near the edge on the short side. In addition, a foot-shaped guide protrusion 22c is provided so as to protrude from the slit 22b and cover the side portion and the distal end portion of the U-slit terminal 11 of the terminal piece 1. The operation block 23 is provided with a tapered portion 23a facing the S-shaped inclination of the clamp terminal 12 of the terminal piece 1 at the bottom, and an operation groove 23b into which a tool such as a flat-blade screwdriver is inserted at the top. An insertion hole 23c through which the cable core W is inserted is provided.

  In the connector block 2, two pairs of terminal pieces 1 are accommodated in the casing 21 symmetrically with the U-slit terminal 11 being reversed in position via a partition wall 21 a. The terminal piece 1 accommodated in the connector block 2 has two pieces of U-slit terminals 11 partially covered by the guide projections 22c of the bottom plate 22 and protrudes outside, and six pieces of clamp terminals 12 connect the operation block 23 to the casing 21. Each window 21d is suppressed.

  As shown in FIGS. 1 and 3, the connector base 3 includes a grooved cable core wire wiring portion 31 to which a cable core wire W connected to the U-slit terminal 11 of the terminal piece 1 is wired, and a plurality of connectors. The block 2 includes a connector block mounting portion 32 which is mounted by selectively aligning the U-slit terminal 11 of the terminal piece 1 or the insertion hole 23c of the operation block 23 of the connector block 2 toward the cable core wire portion 31. The cable core wire wiring portion 31 includes a narrow groove 31a and a wide groove 31b that allow the cable core wire W to be pushed and pushed without difficulty, and the cable core wire W is connected to the connector block mounting portion 32 (an upright piece 32b described later). A cut groove 31c is provided to allow the wiring to pass therethrough. The connector block mounting portion 32 includes a rectangular pedestal 32 a that supports the bottom plate 22 that is the bottom surface of the connector block 2 or the operation block 23 that is the top surface, and a short side surface of the casing 21 of the connector block 2. The upright piece 32b is supported so as to be sandwiched, and the upright piece 32b is provided with a locking groove 32c corresponding to the locking projection 21c of the casing 21 of the connector block 2.

  As shown in FIG. 6, the cover 4 includes an upper open box 41 that covers the connector base 3 attached to the connector base 3, and a lid 43 that is connected to the box 41 by a thin hinge 42 so as to be opened and closed. Consists of. The cover 4 is attached to the connector base 3 by being fitted with a window for allowing the cable core wire W to pass through corresponding to the cable core wire wiring portion 31.

  When using this configuration, first, as shown in FIG. 2, the connector block 2 is attached to the connector block mounting portion 32 of the connector base 3 so that the U-slit terminal 11 of the terminal piece 1 is positioned upward. Therefore, it is preferable to set the mounting state in advance when the product is shipped from the factory.

  Subsequently, the cable core W is connected to the U slit terminal 11 of the terminal piece 1 protruding above the connector block 2. At this time, a part of the protruding portion of the U-slit terminal 11 of the terminal piece 1 from the connector block 2 is covered with the guide protrusion 22c of the bottom plate 22 of the connector block 2 and protected from external pressure or the like. Of course, the U-slit terminal 11 is not bent and damaged by other handling. In addition, since the guide protrusion 22c of the bottom plate 22 of the connector block 2 covers the side portion and the distal end portion of the U-slit terminal 11 of the terminal piece 1, it interferes with the connection between the cable core W and the U-slit terminal 11. There is nothing. Further, the connector block 2 and the connector base 3 are securely attached by the engagement between the engagement protrusion 21c of the casing 21 of the connector block 2 and the engagement groove 32c of the connector block attachment portion 32 of the connector base 3. . Therefore, the connector block 2 is not detached from the connector base 3 due to the stress of the connection of the cable core W to the U-slit terminal 11 of the terminal piece 1. In addition, the connector block 2 may be configured such that the operation block 23 of the connector block 2 is brought into contact with the cradle 32a of the connector block mounting portion 32 of the connector base 3 and the elasticity of the clamp terminal 12 of the terminal piece 1 functions as a buffer material. This contributes to prevention of detachment from the connector base 3.

  Thereafter, as shown in FIG. 1, the connector block 2 is detached from the connector base 3 and inverted, and the connector block 2 is attached to the connector block mounting portion 32 of the connector base 3 so that the operation block 23 is positioned upward.

  As a result, the cable core W connected to the U-slit terminal 11 of the terminal piece 1 is automatically wired and aligned with the cable core wire wiring portion 31 of the connector base 3. Therefore, the cable core W connected to the U-slit terminal 11 of the terminal piece 1 does not get entangled in subsequent wiring work or the like. This attachment state is reliably held by the engagement between the engagement protrusion 21c of the casing 21 of the connector block 2 and the engagement groove 32c of the connector block attachment portion 32 of the connector base 3 as described above.

  Since the mounting depth of the connector block 2 to the connector base 3 is regulated by the receiving base 32a of the connector block mounting portion 32 of the connector base 3, unnecessary contact between the connector block 2 (terminal piece 1) and the connector base 3 is achieved. Damage is prevented, and unnecessary deformation and damage of the cable core W connected to the U-slit terminal 11 of the terminal piece 1 are also prevented.

  Thereafter, as shown in FIG. 3, the operation block 23 of the connector block mounting portion 32 is pushed in, the clamp terminal 12 of the terminal piece 1 is elastically deformed, and the cable core W is inserted from the insertion hole 23c of the operation block 23. Connect to the clamp terminal 12. Then, the cable core W connected to the U-slit terminal 11 of the terminal piece 1 is cut according to the purpose of use.

  After the wiring work such as the necessary connection and disconnection is completed, the cover 4 is put on the connector block 2 and the connector base 3.

  As a result, the connecting portion between the cable core W and the U-slit terminal 11 and the clamp terminal 12 of the terminal piece 1 is covered and dust-proof, so that a short circuit due to an adhering substance or the like can be prevented.

  As shown in FIG. 7, the cable core W is wired in the cable core wiring portion 31 of the connector base 3 so that the operation block 23 is positioned above the connector block mounting portion 32 of the connector base 3. By attaching the connector block 2, it is possible to adopt a usage mode in which the attachment of the connector block 2 to the connector base and the connection of the cable core W to the U-slit terminal 11 of the terminal 1 can be performed simultaneously.
