Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wire wiring connector that allows indoor wiring to be connected easily, error-free, and reliably.

[Conventional technology] The connection of electric wires inside indoor wiring boxes requires a large amount of current to flow through the wires themselves, and is an open connection. A conservative method that prioritized the above was mainly adopted, and while rationalization was being promoted in other fields, old-fashioned wiring methods were still being adopted.

That is, according to the wiring diagram, the workers twisted the core wires of the wires to be connected or crimped them with crimp terminals, and finished each wire by wrapping it with insulating tape.

As a result, workability and efficiency were poor, and the quality of the connections strongly depended on the skill of the workers, so even though rationalization was resisted, the quality was highly variable, and accidents due to incomplete connections were not completely eliminated.

On the other hand, in the early 1980s, a plug-in electric wire connector was developed by a German that made it possible to connect simply by inserting the core wire using a spring, and this connector has now been certified and can be used in Japan, reducing the connection time. In addition to being significantly shortened, the quality of the connection due to the constant connection pressure of the spring no longer depends on the skill of the operator, and there are major benefits such as uniform quality and better insulation. Ta.

This type of plug-in electric wire connector is, for example,
As shown in Publication No. 44239, a plate spring-like clamp spring for holding the core wire corresponding to the core wire insertion hole and each clamp spring are provided in an insulating casing in which a plurality of core wire insertion holes are provided in parallel into which the core wires can be inserted one by one. and a connecting conductor that electrically connects them to each other.By peeling off the insulation coating and inserting the exposed core wire of the electric wire cable into the core wire insertion hole of the insulated casing, the core wire insertion hole can be opened. The clamp spring presses the inserted core wire to prevent it from coming out, and by similarly inserting the core wire of another electric wire cable into the other core wire insertion hole, the core wires of the electric wire cables inserted into this plug-in type electric wire connector can be connected to each other. They are said to be electrically connected to each other.

According to such a plug-in wire connector, the wires can be connected by inserting the core wires of the wires of the system to be connected into the same plug-in wire connector, making the work extremely easy; , it is possible to ensure uniform quality that is independent of the skill of the operator, and it is also possible to obtain high reliability in terms of insulation.

[Problems to be Solved by the Invention] By the way, such a conventional plug-in type electric wire connector is configured by providing a plurality of core wire insertion holes in one housing.
Electric wire connections of the same system are used independently for each system. Therefore, except for the fact that the connection work is much easier and stable quality can be ensured, basically it is the same as connecting the connecting ends of electric wires with crimp terminals, and each wire is connected one by one while considering the wiring design. There is no substitute for connecting, and it is not possible to systematically understand and work with plug-in electric wire connectors. That is, conventional devices are core wire connectors that facilitate the connection of core wires, but are not designed to allow systematic wiring just by looking at the core wire insertion holes of the plug-in type electric wire connector. Therefore, even if the connection is easy, you must consider which wire connector to use to connect the wires, check the wiring diagram and the wire connectors and wires, and proceed with the work.The wire connections must be made inside the terminal box. The work efficiency is extremely low because the work is done in narrow and difficult places such as ceilings and ceilings.
There is also a big concern about incorrect connections.

Therefore, an object of the present invention is to enable systematic and easy-to-understand wiring connections, thereby improving work efficiency even in narrow or difficult places, and making it possible to avoid errors. An object of the present invention is to provide a plug-in type electric wire connector that can prevent connection.

[Means for Solving the Three Problems] In order to achieve the above object, the present invention is configured as follows. In other words, there is an insulating casing in which a plurality of electrical wire insertion holes are arranged in a matrix at predetermined intervals and the divisions are displayed according to the system; An electric wire connecting conductor that is electrically conductive to the wire, each having a core wire insertion part into which the core wire of the inserted electric wire can be inserted, corresponding to the position corresponding to the wire insertion hole, and a holder equipped with a clamp part for clamping the inserted core wire. It is configured by providing a conductor.

[Function] This connector with such a configuration has a plurality of wire insertion holes arranged in a matrix at predetermined intervals in the insulating casing, and the multiple wire insertion holes are not classified according to system. It is. Holding conductors are arranged in this insulating casing in correspondence with each of the divided systems. Each holding conductor is a wire connecting conductor that is electrically conductive in each of the divided systems, and each has a core wire insertion portion into which the core wire of the inserted wire can be inserted, corresponding to a position corresponding to the wire insertion hole. The core wire is provided with a clamp portion for clamping. Therefore, in accordance with the indoor wiring design, decide which system from the above-mentioned system classifications will be used for wiring connections of appliances, etc., and insert each wire connecting to that appliance into the wire insertion hole of the corresponding system. . The core wire of the inserted electric wire is clamped by the clamp part and firmly held by the holding conductor. In this way, the insulated casing has a plurality of wire insertion holes at predetermined intervals, and is divided into different systems and has a holding conductor for the inserted core wire inside.The wire insertion holes for each system can be used to By inserting the core wire of a connecting wire in the same system into a wire insertion hole in the same system, the connecting conductor of that system will be electrically connected to the wire inserted into another wire insertion hole in the same system. The electric wire inserted into the electric wire insertion hole is clamped and connected by the clamp portion of the holding conductor.

Therefore, according to the present invention, it is possible to make systematic and easy-to-understand wiring connections, and since connection can be made by simply inserting electric wires, work efficiency can be improved even in narrow spaces or places where work is difficult. It is possible to provide a plug-in type collective electric wire wiring connector that can prevent erroneous connections.

[Embodiment 1] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing an example of the basic configuration of this device, and shows a collective wire connection connector of a direct load system. As shown in the figure, this connector has a three-system n connection point configuration corresponding to the commercial power supply lead-in line. That is, in the figure, 1 is a square box-shaped casing made of an insulating material such as nylon or other synthetic resin, 2a to 2C are connection holding fittings, and 3 is an insulating material similar to that of the casing l. It is a formed bottom plate. Connection holding fitting 2a
~2c is a cylindrical piece formed by processing a metal plate with a large elastic force such as stainless steel into a shape with a cross section like a letter 0, and -2c has holes 20 on the side for inserting the core wires of the electric wires at predetermined intervals. are drilled therein, and a tongue-shaped clamp spring portion 21 is formed corresponding to each of these holes 20. And these clamp spring parts 21
is bent inwardly, and when the core wire of the electric wire is inserted into the hole 20, it contacts and is pressed by the clamp spring portion 21 corresponding to the hole 20, and is sandwiched between the inner wall and the core wire. It is designed so that it does not come off. A second band-shaped current-carrying plate made of a highly conductive material, such as a copper plate, is attached to the inner side of each of the connecting and holding fittings 2a to 2C, as shown in the figure. This current-carrying plate 21 is a connection holding fitting 2a.
A contact 2M bulged in a semi-cylindrical shape is formed along the longitudinal direction at a position opposite to the tip of the tongue-shaped clamp spring portion 21 of ~2c.
Due to the contact by the tip of the clamp spring part 21 of the connection holding fitting, the core wire of the inserted electric wire becomes a point contact structure, and the pressure of the spring is concentrated to contact the current carrying plate 2L.
Since reliable contact is possible and both are good conductors, the electrical resistance between the inserted core wire and this current-carrying plate 2L can be made extremely small.

Further, the connection holding fittings 2a to 2c are installed in the housing l, and each of the connection holding fittings 2a to 2c is installed in the housing l.
Partition walls (not shown) are formed along the longitudinal direction of each connection holding fitting 28, and each connection holding fitting 28 is fitted into a groove formed by the partition wall.
~2C will be stored in a mutually insulated state.

The inserted connection holding fittings 2a to 2 are attached to the upper surface of the housing I.
Wire insertion holes 10 are made corresponding to the core wire insertion holes 20 of c, respectively, and by inserting the tip of the wire from which the coating has been stripped as shown in FIGS. 6 and 7, As shown in FIG. 1θ, the core wire is inserted and held in this connector, and is pressed obliquely by the tip of the clamp spring portion 21 and pressed against the current-carrying plate 2L, and is held while maintaining conductivity.

FIG. 2 is an exploded perspective view showing an example of a combination type collective electric wire wiring connector that is configured in one system unit and uses necessary system readings in combination. In the figure, 201 is a casing, and this casing 201 is made of an insulating material such as nylon or other synthetic resin and has an open top. A connection holding fitting 202 having the structure is stored, and the housing 2 is opened from above.
A lid 20 made of the same material as the housing 201 covers the opening of the housing 201.
3 is attached and configured. The lid 203 has a hole 202 for inserting the core wire of the inserted connection holding fitting 202 on its upper surface.
Wire insertion holes 203a are formed corresponding to the holes 203a, and the ends of the wires with the coating stripped therefrom are inserted into the holes 203a to hold the wires. M2O3 has tenons 203b, which are engagement protrusions, protruding from its side surface at predetermined intervals, and a mortise hole 201a that engages with the tenons 203b is formed on the side of the housing 201.

Therefore, when the lid 202 is inserted into the housing 201, the tenon 203b engages with the mortise 201a, and it cannot be removed.

Further, on both sides of the housing 201, concave and convex portions 201b and 201c for fitting and coupling are provided at predetermined intervals, respectively.
These are formed in a male/female relationship on the left and right sides of the housing 201 so that they can be connected to adjacent housings 201 when the housings 201 are arranged in number as shown in FIG. 3. . In addition, when using stainless steel for the connection holding fitting 202, as a measure to ensure good conductivity between the core wires to be connected and held, the connection holding fitting 202 is placed inside the cylindrical connection conductor 202 in contact with its inner wall. Similarly, an energizing plate 202A made of a strip-shaped copper plate is arranged. This current-carrying plate 202A has a contact 202B bulged in a semi-cylindrical shape along its longitudinal direction at a position opposite to the tip of the tongue-shaped clamp spring portion 221 of the connection holding fitting 202, and this bulged contact 202B Due to the contact by the tip of the clamp spring part 221 of the connection holding fitting 202, the core wire of the inserted wire becomes a point contact structure, and the pressure of the spring is concentrated and brought into contact with the current-carrying plate 202A made of a conductive copper plate, so that more reliable contact can be achieved. This is possible, and since both are good conductors, the electrical resistance between the inserted core wire and this current-carrying plate 202A is also extremely small.

If you combine the required number of individual wire assembly connectors with this configuration as shown in Figure 3, you will be able to create something similar to the integrated type shown in Figure 1, and since you can freely combine them, it is possible to System, 4 system, 5 system, etc., you will be able to obtain the required configuration.

The configuration of such a collective wire connector is conceptually shown in FIG. 11(a), and is for direct loading. Then, when wiring, as shown in Figure 7, each system of the collective wire connector is connected, and, for example, the 3-wire power supply wire is inserted one wire at a time through the wire insertion hole, and the in-house wiring of appliances and equipment is done. Accordingly, the connecting wires of each system are inserted using any wire insertion hole of each corresponding system of this collective wire connector to connect the wires. Anyone can understand that each row of the collective wire connector is one system from the structure, but to make it more clear, it is possible to color each system to match the wire color, display it with a label, or display it on a system-by-system basis. Appropriate color coding should be done, such as by forming a frame surrounding the wire insertion hole in that area or by marking it, and the color of each covering of the core wire of the wire used for power distribution should be It is specified by the relationship with the phase in the line, so it should be adjusted accordingly.

As a result, an electrician can instantly determine the color of each coating on the core wire of an electric wire, which is specified in relation to the phase of the lead-in wire, so that it can be directly wired to appliances, etc. without intervening switches, etc. For loads, insert the core wire of the wiring wire from the appliance, etc. into the empty wire insertion hole of the corresponding system (LB (black line system), LW (white line system), LG (green line system)) according to the color of the sheathing. The work is simple, and you can proceed with the wiring connection work as designed without hesitation.Moreover, you can check the wiring immediately by looking at the collective wire connector, so you can avoid incorrect connections. The danger of

The above shows a collective type electric wire wiring connector for direct loads.

In homes, buildings, etc., there are many things that require wiring to appliances and equipment via switches.

Next, a collective electric wire wiring connector for a switch circuit that connects wiring to such devices will be described.

Figure 11 (b) shows the collective wire wiring connector for switch circuits.
), there are basically two main circuit systems (for example, LB
(black line system) and LM (white line system)) and
A branch connection terminal section (F) is required to form a round trip path to the switch. The distribution connection terminal part F has two wire insertion holes.
A point one is sufficient, and these are provided for several IM systems. The example in FIG. H shows a structure in which the distribution connection terminal section F is sandwiched between two main circuit systems for several systems.

To explain this in terms of a freely combinable type, it is as shown in Figure 4, which consists of two collective electric wire wiring connectors as shown in Figure 2, and a distribution type in which the collective electric wire wiring connector is shortened to have two wire insertion holes. The connecting terminal portion F is manufactured as a housing structure having a side fitting structure, and is assembled and fixed to each other as shown in FIG. 4, as shown in FIG. 5. In addition, in FIG. 4, (a) is a plan view, (b) is a front view, and (e) is a side view. The connection holding fitting structure of the two-hole distribution connection terminal portion F is basically the same as that described above, but if it is structured as shown in FIGS. 8 and 9, the stability will be higher.

That is, in FIG. 8, a current-carrying plate 202A made of a strip-shaped copper plate is disposed in a cylindrical connection-holding fitting 202 in contact with its inner wall, and this current-carrying plate 202A is located at a position opposite to the tip of the clamp spring portion 221 of the connection-holding fitting 202. A contact 202B bulged in a semi-cylindrical shape is formed along the longitudinal direction of the contact 202B. Furthermore, this current-carrying plate 202A has an unevenness in the signal wire insertion direction at the position of the core wire insertion hole, and a groove 2020 for guiding the core wire. It is formed.

Therefore, the core wire is guided in this core wire guide groove 202C, and is securely inserted into the bulged contact 202B and the tip of the clamp spring portion 221 of the connection holding fitting 202. Then, due to the contact between the contact 202B and the tip of the clamp spring part 221 of the connection holding fitting 202, the core wire of the inserted wire becomes a point contact structure, and is brought into contact with the current-carrying plate 202A by the pressure of the spring, so that more reliable contact is possible. Moreover, since both are good conductors, the electrical resistance between the inserted core wire and this current-carrying plate 202A is also extremely small.

FIG. 9 shows a connection holding fitting 202 consisting of an L-shaped main body 301 made of a good conductor such as a copper plate, and a suppressing piece 302 that is fitted to the L-shaped main body 301 to simplify the structure. The suppressing piece 302 is made of a highly elastic metal plate such as stainless steel, and is formed into a comb-teeth shape by bending it to have a cross-section shaped like a square. 303 is a core wire insertion hole, and 304 is a tongue-like piece. The clamp spring portion 305 becomes a fitting piece portion. The attachment is maintained by fitting between the surface where the core wire insertion hole 303 is formed and the fitting piece portion 305 into the surface where the wire insertion hole 30B is formed in the L-shaped main body 301. In addition, the second current-carrying plate 202
Similar to ^, the main body 301 is formed with unevenness in the signal line insertion direction at a position corresponding to the core wire insertion hole 303, and a groove 308 similar to the core wire guide groove 2020 is formed.

Therefore, the core wire is guided in this core wire guide groove 308, and is securely inserted into the bulged contact 307 and the tip of the clamp spring portion 304 of the pressing piece portion 302.
can be retained. 8 and 9, (a) is a side view, and (b) is an exploded perspective view.

Further, the structure shown in FIG. 9 can naturally be applied to a structure having two or more core wire insertion holes.

An example of the use of this collective type electric wire connection connector will be explained next. The wiring example of a house shown in FIG. 12 will be explained using a direct load type collective wire connection connector as an example. In this case, as shown in FIG.
Place the collective electric wire connection connector inside, and connect the edge line of the power supply line to the LG (4m line) system connection line, LM (white wire) system connection line, and LB (black line) system connection line of the collective electric wire connection connector. white line.

Connect the edge wire, white wire, and black wire of the connecting wire of C70, respectively, and plug it into the outlet C.
Connect the white wire and black wire of the T3 connection wire to the LM system connection line and LB system connection line, respectively, and connect the white wire and black wire of the connecting wire for the fan and lighting light wires with switches to the LM system connection line and LB system connection line. The wires on the switch side are connected individually in the switch box, as shown in FIG. 13(b). In this way, in addition to the case where a direct load type connector is used for direct wiring connection to the load side, it can also be used for switch-mediated wiring connection.

Next, as shown in FIG. 14, an example of house wiring will be described in which all the wiring including the wiring to the switch is independently wired to each appliance using a collective wire connector. in this case,
Use collective wire connectors for switch circuits and collective wire connectors for direct loads. In this case, each group type electric wire connection connector as shown in Fig. 15 is arranged in the joint box jB, and the Lw (white wire) system connection line, L

Also, use the branch connection terminals F and 1 of the collective electric wire connection connector, the V system connection line, and the LB system connection line to assemble the round trip path to the main circuit of the fan or light and the switch circuit. Make the connection. In addition, the collective wire connection connector for direct load has its Lw (white wire) connection line, LG (edge line) connection line, LD (

CTI outlets for each system connection line and LB system connection line.

Connect the edge wires, white wires, and black wires of the connecting wires of C70, respectively, and connect the ground wire of the fan to the LG system connection line of the collective wire connection connector.

As described above, according to the present collective electric wire connector, wiring can be performed in an easy-to-understand manner according to various variations, and the connection work can be easily performed.

Therefore, when pipe wiring or wiring inside a box is required due to heavy ceilings, such as in high-rise houses, it is conventional to use Iv wires (independent wires with one core wire system) or VVF wires (flat cables with several core wires). At the end of the line, the wires of the same system were connected one by one using the sleeve crimping tape wrapping method or wire connectors for plug-in connection. , it becomes possible to connect each system on this one connector.

In this way, this device includes an insulating casing in which a plurality of wire insertion holes are arranged in a matrix at predetermined intervals and the divisions are displayed according to the system; A wire connecting conductor that is electrically conductive in each system, each having a core insertion part into which the core wire of the inserted wire can be inserted corresponding to the position corresponding to the wire insertion hole, and a clamp that clamps the inserted core wire. The holding conductor is provided with a holding conductor having a section. In other words, this connector has a plurality of wire insertion holes arranged in a matrix at predetermined intervals in an insulating casing. Holding conductors are arranged corresponding to the divided systems.

Each holding conductor is a wire connecting conductor that is electrically conductive in each of the divided systems, and each has a core wire insertion portion into which the core wire of the inserted wire can be inserted, corresponding to a position corresponding to the wire insertion hole. The core wire is provided with a clamp portion for clamping.

Therefore, in accordance with the indoor wiring design, decide which system from the above-mentioned system classifications will be used for wiring connections of appliances, etc., and insert each wire connecting to that appliance into the wire insertion hole of the corresponding system. Then, the core wire of the inserted electric wire is clamped by the clamp part and firmly held by the holding conductor.
