い。In the unit frame of a closed switchboard such as a control center, the switches, breakers, auxiliary relays, etc. of the control equipment that need to be inspected are installed on the front side with the unit door, and the transformation for ammeters that do not require inspection. Vessel (CT)
Some are attached to the back side. Further, there is a tendency to use the back side of the unit frame for wiring so that the front side of the unit frame is not congested by the wiring. On the other hand, in the unit frame having such a structure, the terminal connecting portion for connecting the load-side lead-in electric wire in the wiring duct is located on the side of the unit frame in the closed switchboard from the viewpoint of workability on the customer side. It is convenient to install it on the side of the unit frame so that the wiring work can be performed from the front of the wiring duct. However, from the manufacturer's point of view, depending on the rating, it is thick and difficult to bend, and it is difficult to make the wiring process compact.Because the main circuit wiring derived from the transformer and other control equipment is complicatedly bent and routed to the side of the unit frame. It is inconvenient in terms of downsizing the closed switchboard on both the front side and the rear side of the unit frame. Therefore, in order to avoid complicated bending when connecting the wiring inside the unit frame that is led out to the rear side of the unit frame, the control device side on the rear side of the unit frame and the load side electric wire located on the side of the unit frame An electric wire connector to intervene is required. On the one hand, this electric wire connector requires that the consumer side must be able to easily perform work such as wiring from the front side of the wiring duct that is narrowed due to miniaturization, and on the other hand, the manufacturer side is also the manufacturing unit. It is necessary to satisfy the two requirements that the wiring within the frame should be easy and compact. Therefore, the connecting direction of the terminal connection part of the transformer and other control equipment and the connecting direction of the terminal connection part of the load-side electric wire inevitably form a predetermined angle so that the working direction for connecting the terminals (general Of course, the axial direction of the terminal tightening bolt will also be different. Further, in the closed switchboard having the above-described structure, the positional relationship between the connection work parts on the consumer side and the manufacturer side needs to be on the front side and the back side or the left side and the right side with the wire connector interposed therebetween. An example of an electric wire connector in which the connecting work directions of the terminal connecting portions at both ends form a predetermined angle is, for example, as shown in FIG.
There is a terminal board disclosed in No. 6684. This terminal board
The connection work parts of the terminal connection parts are located on the same side, and the connection work directions are perpendicular to each other. The connecting work direction when connecting the electric wires is the direction indicated by arrows C and D. In this structure, since the connection work part of the terminal connection part is on the same side, the connection work part on the consumer side and the manufacturer side must be in the front and back positional relationship with the electric wire connector interposed therebetween. In the case of a switchboard, the terminal board of this structure cannot be used.

である。The present invention will be described in more detail based on the embodiments shown in the drawings. 1 is a sectional view showing the structure of the electric wire connector, FIG. 2 is a front view of a terminal block, FIG. 3 is a bottom view, FIG. 4 is a sectional view taken along line I-I, and FIG. 5 is a front view of a conductive plate. , FIG. 6 is a side view. Reference numeral 100 is an electric wire connector provided with the terminal block 1. The terminal block 1 is made of an insulating synthetic resin. The terminal block 1 is provided with a conductive member accommodating portion 11 which is partitioned by a partition wall 10 and is provided for each phase.
Each conductive member accommodating portion 11 is provided with a connection space 12 and a connection space 13 provided above and below in the drawing. Connection space 12
The connection space 13 and the connection space 13 are formed so that the connecting directions of the electric wires are substantially perpendicular to each other, and are connected by the insertion holes 15. The wall portion 101 of the connection space 12 is provided with a protrusion 14 on the back side to form a hook hole 16. The hook hole 16 has a nut seat portion 161 that can be mounted with a little margin without rotating a nut 32 of a connection member to be described later, and a nut seat portion 161.
It is composed of a bolt relief hole 162 connected to the inner part of the bolt. An insertion hole 17 is provided in the wall portion 102 of the connection space 13 so that the hook hole 16 and the axis line are orthogonal to each other. The insertion hole 17 also includes a nut seat portion 171 and a bolt escape hole 172, similarly to the hook hole 16. A mounting portion 18 for mounting in the wiring duct is provided so as to project from the front surface of the terminal block 1, and mounting holes 181 are provided at two locations in the mounting portion 18. The insertion hole 17 is formed on the back side of the mounting portion 18. The insertion hole 15 that connects the connection space 12 and the connection space 13 is formed so that the gap on the connection space 13 side is large and becomes slightly smaller toward the connection space 12 side. Then, the conductive plate 2 is mounted in each insertion hole 15. As shown in the figure, the conductive plate 2 has an L shape bent at a substantially right angle, and has a long side as an insertion portion 21 and a short side as a hook portion 22. A mounting hole 23 is provided on the end side of the insertion portion 21, and a mounting hole 24 is also formed on the end side of the retaining portion 22. When the mounting holes 23 and 24 are inserted, the hook holes 1 are provided.
It is provided at a position corresponding to 6 and the insertion hole 17, and the connection member 3 is attached to the attachment holes 23 and 24. The connection member 3 includes a bolt 31, a nut 32, a spring washer 33, and a washer 34. In addition, a circular engagement protrusion 25 is provided by stamping at approximately the center of the insertion portion 21. Engagement protrusion 2
The protruding height of 5 is set to a height at which the conductive plate 2 is fitted in the insertion hole 15 slightly tightly when the conductive plate 2 is inserted into the insertion hole 15. It should be noted that the conductive plate 2 having different plate thickness is used depending on each rated capacity, but since the engaging thickness obtained by combining the plate thickness and the projecting height of the engaging projecting portion 25 is constant, the plate having different plate thickness is used. However, they can be inserted into the same insertion hole 15, and the terminal block 1 can be shared. With reference to the drawings, the mounting structure and action of each conductive plate 2 and terminal block 1 will be described together. First, the nut seat portions 161 and 171 of each conductive member accommodating portion 11
The nut 32 of the wire connecting member 3 is attached to. Next, the conductive plate 2
Insert the insertion portion 21 of the above into the insertion hole 15 of the terminal block 1,
The engaging projection 25 and the inner wall of the insertion hole 15 are brought into contact with each other to make the conductive plate 2
Is press-fitted into each insertion hole 15. As a result, each conductive plate 2 is temporarily fixed to the conductive member accommodating portion 11 of the terminal block 1, and the nut 32 is also pressed by the insertion portion 21 and the hooking portion 22 of the conductive plate 2 so as not to come off from the nut seat portions 161 and 171. Then, the bolt 31 is inserted into the mounting hole 23 through the spring washer 33 and the washer 34, and is screwed to the nut 32 of the hook hole 16 to form a wire connection portion. As a result, the conductive plate 2 is fixed to the wire connecting member 3, and due to the fitting contact between the wire connecting member 3 and the locking hole 16, the conductive plate 2 does not move in the insertion direction and does not come out of the insertion hole 15. Similarly, the bolt 31 is inserted into the mounting hole 24 through the spring washer 33 and the washer 34, and the nut 3 of the mounting hole 17 is inserted.
It is screwed to 2 and used as a connection part. As described above, the conductive plate 2 is fixed to the terminal block 1 by abutting the portion of the conductive plate 2 where the engaging protrusion 25 is provided with the inner wall of the insertion hole 15 and connecting the wire connecting member 3.
The engaging holes 16 and the engaging holes 16 are brought into contact with each other in the insertion direction of the conductive plate, and the tightening force by screwing the bolts, nuts, etc. of the wire connection portion is not used, and the tightening force is used only for wire connection.
Therefore, unlike the conventional electric wire connector, it does not have a structure in which the conductive plate is fixed and connected at the same time with the same bolt, so that there is no inconvenience that the mold is cracked due to excessive tightening at the time of connection. Also, since there is no such concern, there is an advantage that the tightening force when connecting can be increased. If the rated capacity changes later, it must be changed to a conductive plate 2 having a different plate thickness, but as described above, the terminal block 1
Since a common one can be used, only the conductive plate 2 needs to be replaced, and it is not necessary to replace the terminal block 1 as in the conventional case. Since the terminal block 1 is also used as a component in this way, the cost can be reduced and the inventory can be easily managed. FIG. 7 is a schematic explanatory view showing a mounting state of the closed switchboard to the unit frame. The electric wire connector 100 is a closed switchboard 5 with a mounting screw 4.
No. 00 is attached to a mounting portion 51 provided on the unit frame 5 at an angle with respect to the insertion / removal direction of the unit frame 5. 5
Reference numerals 2 and 53 are through holes through which the electric wire connector penetrates the unit frame 5, and the electric wires 6 and 7 are connected to the electric wire connector 1 from the outside of the unit frame 5.
It is introduced into the connection spaces 12 and 13 of No. 00 and can be connected to the conductive plate 2. The connection space 12 side is the connection side of the electric wire 6 on the control device side, and the connection space 13 side is the connection side of the load side electric wire 7. The work directions at the time of wire connection work of the respective parts are as shown by arrows A and B, and the work parts are on the opposite side with the terminal block 1 sandwiched between them, and the position where the work parts are introduced from different sides of the rear side and the lateral side of the unit frame 5.
