【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings. Figure 1 shows the parts related to this invention. FIG. 2 is an exploded perspective view of the branch connector, and FIGS. 2(A) and 2(B) are perspective views of the case of the same connector. It is a diagram. The case of this branch connector has a structure as shown in Figure 2. Sometimes, the case 1A and the case 1B are joined in the middle. This junction It may be worn or fixed with screws. This case as shown in Figure 1 The F cable that will be wired at the construction site is plugged in and the branch wiring is installed. A branch connection section 10 to which a power outlet is connected is housed. Branch connection part 10 consists of three branch connectors 10A, 10B, 10C in the illustrated embodiment. It is a three-pole type. The number of branch connectors housed in the case is One, two, or even more, to accommodate the number of branch wires required. Also good. In this case, the case has a dedicated case according to the number of branch connectors housed in the case. It is necessary to prepare the following.

[0007] Each branch connector has a plug connection part for plugging and connecting the core wire of the F cable. 11A, 11B, and 11C are provided, respectively. This plug-in connection Acts as a primary connection when the power or primary side of the cable is plugged in In addition, if the load side or other branch F cable, that is, the secondary side, is When pushed in, they each function as secondary side connections. these Each plug connection is provided with three plug electrodes. For example, plug-in connection Plug-in electrodes 12, 13, 14 are provided in the plug-in connection portion 11A of the device 10A. ing. Each of these plug-in electrodes consists of a pair of electrodes, and each electrode has a pair of electrodes. The structure is such that elastic force can be applied to the electrode elements in the direction of mutual contact. It is. For example, regarding the plug-in electrode 12, the electrode element constituting the plug-in electrode 12 12A and 12B are designed so that elastic force can be applied in the direction in which they contact each other. If the core wire of the F cable is inserted into this insertion electrode at 12, the core wire is sandwiched between the electrode element 12A and the electrode element 12B. Additionally, individual When a core wire is inserted into the electrode as described above, the core wire can be easily pulled out. To prevent this, there are multiple claws on the part that holds the core wire to prevent it from falling out. There is. For example, regarding the electrode element 12A, there are two claws 15 and 16. Of course Similarly, two claws are provided on the electrode element 12B opposite to the electrode element 12A. be. These electrodes are the bases 17, 18, 19 that form the basis of the configuration of the branch connector. and one end thereof is firmly fixed using a screw. Furthermore, this The can also be fixed by caulking. Therefore, the F cable is attached to each plug-in electrode. When inserting a core wire, the core wire will be pinched by each electrode with considerable force. At the same time, the claws hold it firmly in place to prevent it from falling out. Ma In addition, each branch connector has a gap between each electrode when pushed in the direction A shown in the diagram. A release lever is provided that allows you to push the gap apart and remove the core wire held in your mouth. I'm being kicked. For example, the release lever 20 is not provided for the branch connector 10A. However, when this release lever 20A is pushed in the direction of A, the opposing Three electrodes, for example electrode 12, and two other electrodes at the same time in the direction B shown in the figure. It will be expanded. Therefore, by pressing this release lever 20, the above Insert the core wires held by the insertion electrodes 12, 13, and 14 into each This means that the electrodes can be removed at the same time. In addition, in this example, the earth electrode Although we have shown an example of a type equipped with The same applies to a type with four plug-in electrodes.

[0008] Each connection, where a pair of electrodes are screwed together, has an adjacent plug-in terminal. Copper bars 21, 22, and 23 as crossover wiring connecting each connection part of the poles are shown in the figure. Connect as shown. In addition, connection wires 40, 41 to which the outlet is connected, 42 are also connected as necessary. In this example, three outlets are provided. Since it is a branch connector, connection wires are connected to all connections. Of course The connection between the copper bar and the connecting wire should be made at the same time when screwing each electrode. It will be held on.

[0009] The branch connection section 10 assembled as described above is housed in the case 1A. However, in this storage, the fitting part 25 of the plug-in connector 10A is connected to the fitting part 25 of the case 1A. The fitting part 26 of the plug connector 10B is inserted into the fitting part 31 of the case 1A at the part 30. By inserting the fitting parts 27 of the connector 10C into the fitting parts 32 of the case 1A, That's what I'll do. Next, in this state, align case 1B with case 1A and remove it. the branch connection part 10 is completely housed therein. This case 1B is installed When inserted, the respective locking lugs provided inside the mating connector will secure the respective plug connector. One side of the base will be pressed toward case 1A, and this will cause its Each plug connector will be firmly fixed. Specifically, the fixing protrusion 3 Two points of the base 17 are pressed against the fitting part 30 side by 0A and 30B. Similarly, the base 18 is fixed by the fixing protrusions 31A and 31B. The base 19 is pressed by 32A and 32B, respectively. Ma In addition, each of the electric wires 40, 41, 42 to which an outlet (not shown) is connected Bush portions 40A, 41A, and 42A are formed in cases 1A and 1B, respectively. Insertion hole forming notches 43A, 44A, 45A and 43B, 44B, 45B. Therefore, each will be caught. Therefore, some external force is applied to the connecting wire. Even if force is applied, the force is not directly applied to each screwed connection. Sara The respective release levers including the release lever 20 are inserted into the insertion openings 46, 47, It is inserted into 48. This allows each plug-in electrode to be The core wire can be released.

0010 If you look at the cross section of the main parts of the branch connector assembled in this way, you can see it as shown in Figure 3. I'm going to growl. As shown in the figure, the core part of the F cable is connected to the electrode 12A. 12B with a predetermined clamping force, and the claw 15, It is regulated by 16. To release this restriction, press the release lever 20. It is sufficient to push the pole element 12A in the direction away from the electrode element 12B, and thereby the core Line parts are easily removed. In other words, the connection of the F cable to the plug-in electrode is After removing the cable sheath and exposing the core wire, e.g. This is done by inserting it into the insertion hole 49 or the like. Therefore, inserting the F cable Connection to the electrode can be made with a single touch, and it can also be disconnected or pulled out. This can be done with one touch by pressing the release lever.

[0011] Furthermore, the case 1B is provided with a pilot lamp 50; The rotary lamp 50 is connected to either connection of the bayonet connector. others Therefore, by lighting this pilot lamp 50, the connected F cable is activated. This means that it can be easily determined whether the line is in a line state or not. Furthermore, in case 1A, A hanging portion 55 is provided for hanging this branch connector. In this hanging part 55 A notch is formed through which the F cable can be guided from the outside into the inside. In other words, only one of the arches that make up the hanging part is connected to case 1A, and the other On the other hand, there is enough space to guide the F cable into the arch. It has a so-called cantilever support structure. Therefore, as shown in Figure 4, this branch code After passing the F cable to be connected to the connector through the hanging part 55 as shown in the figure, If you connect it to the plug-in connection, you will need to prepare a hanging wire, etc. to hang it. This means that you can hang it without any problems. In addition, the structure of this hanging part 55 There are many other options available, and their locations are as shown above. If waterproofness of the branch connector can be ensured, install it not only on the side but also on the side of the branch connector. Also good.

0012 Also, by being suspended in this way, it is connected to the branch connector. The F cable and all connection wires leading to the outlet should exit from the bottom side. Therefore, it is waterproof.

[0013] As mentioned above, in the branch connector of this embodiment, there are three plug connectors 10A, Equipped with 10B and 10C, and the connection wire to the outlet is also connected to each plug connector. Since three wires are connected, new branch wiring is required at the construction site, and a new branch wiring is required at the construction site. Even if additional management is required, it can be easily handled. That is, something like this In this case, cut the existing branch wiring F cable from the middle and connect the F cable. Remove the cable sheath from the mains side and connect the F cable on the power side to one of the three plug connectors. Plug-in connection and also plug-in the F cable on the load side to one of the remaining plug-in connectors. Then, connect the F cable for branch wiring to the remaining plug connection, If one of the F cables is passed through the hanging part 55 as described above, then these The expansion has been completed.

[0014]

[Effect of the idea] As described above, according to the present invention, it is easy to add outlets and branch wiring. You will be able to Also, the power supply side or By passing the load side electric wire through the suspension part, it can be done without providing any particular suspension wire. This means that it can be hung. When suspended like this Since the electric wires and connection wires are located on the underside of the case, it is inevitably difficult to protect against protection. Aqueous properties can be ensured. Additionally, there is an indicator to show whether the wire is live or not. It is very effective for safety because it can be easily confirmed.
