When the slide member 45 is slid so as to spread in a direction opposite to each other with a tool such as a flat-blade screwdriver, the pressing protrusion separates up and down while pressing the slope of the engaging protrusion 52, so the release member 50 is The pressing piece 51 presses the corresponding pressing spring 47, and the holding of the electric wire between the terminal fitting 46 and the pressing spring 47 is released. The leaf spring 53 is for urging the slide member 45 in a direction in which the slide members 45 are always in contact with each other.

  The connecting and fixing plate 40 is made of an elastic metal plate, and at least the surface side is coated with an epoxy-based, polyester-based or PES-based resin paint or film. As shown in FIG. Information a such as a circuit diagram (see FIG. 7B) for explaining the internal structure is formed by laser processing. A circular opening 55 that exposes the end face of the insulator 25 described above is formed in the center of the connecting and fixing plate 40, and a locking piece 41 that is a locking means is bent to the back side in the center of both ends in the longitudinal direction. Is formed. The locking piece 41 is formed with a locking hole 56 and a base portion is formed with a notch 57 so as to have a spring property.

  According to the wiring connector having the above-described configuration, one blade receiving terminal 6 of the connection terminal member is placed in one insulating case 4 in the first partition 8 of the insulating case 4, and the quick connection terminal 7 is second in the insulating case 4. 8A and 8B, the shaft portion 25a of the insulator 25 is accommodated in each partition 9, and the other blade receiving terminal 6 and the quick connection terminal 7 of the connection terminal member 30 are connected to each other as shown in FIGS. As shown in FIG. 8 (c), the ribs 26 of the insulator 25 are fitted into the fitting grooves 18 formed in the notches 17 and then insulated as shown in FIG. 8 (d). The opening sides of the case 4 face each other. In this state, as shown in FIG. 9A, the engaging convex portion 15 of the other insulating case 4 is engaged with the engaging concave portion 16 of the other insulating case 4, and the engaging concave portion 16 of the other insulating case 4 is engaged. Since the connection case body 3 is assembled so that the engagement convex portions 15 of one insulating case 4 are engaged with each other, the coupling fixing plates 40 are overlapped from the upper and lower surfaces of the connection case body 3, respectively. What is necessary is just to press so that the latching hole 56 of the latching piece 41 may be latched by the latching convex part 42. FIG.

  In the wiring connector assembled in this way, as shown in FIG. 9B, the insulating cases 4 are insulatively engaged with each other by the engaging convex portions 15 and the engaging concave portions 16, and are insulated by the connection fixing plate 40. Since the cases 4 are fixed so as not to be separated from each other, the insulation cases 4 are not displaced with respect to the external pressure from the top, bottom, left and right, and the insulation cases 4 are separated from each other unless the connection fixing plate 40 is removed. Absent.

  And since the display a, such as a connection structure and a connection instruction | indication, is made | formed by the laser processing on the upper surface of the connection fixing board 40, what is necessary is just to connect an electric wire and a harness plug according to the display.

  When the connection is completed, a screw 28 may be inserted into the through hole 27 of the insulator 25 and the wiring connector A may be fixed to the wiring path surface with the screw 28.

  According to the above-described wiring connector, since the wire connecting portion 11 and the branch connecting portion 12 are arranged in a vertical arrangement, the lateral width is made narrower than the conventional wiring connector in which the connecting portions are formed in a horizontal arrangement. Therefore, when installed on the OA floor, it is possible to realize a wiring connector that can be installed in a correct state (which can be fixed to the wiring path surface with screws) even in a narrow wiring path.

  Moreover, since the insulating cases 4 are brought together and joined together, and the state can be maintained by the connecting and fixing plate 40, screws and caulking for fixing the insulating cases 4 to each other are not necessary, and a tool for that is also necessary. Therefore, the efficiency of the assembly process can be improved.

  The display a formed by laser processing on the surface of the connection fixing plate 40 may be formed in advance in the state of the connection fixing plate 40 in the state of a part, or the last in the state where the wiring connector is assembled. Laser processing may be performed in the process.
