Wire connecting device for electric connector

The present invention relates to a wire connection device of an electrical connection device, and more particularly, it is connected to a connection terminal such as an electric wire, a plug or an outlet by a simple operation without separate disassembly and disassembly of the wire coating, and at the same time, the wire is sufficiently filled with a case. It relates to a wire connection device of the electrical connection mechanism to be fixed.

In general, an electrical connection device for supplying power to an electric appliance may include an outlet, a plug, or various switches.

Such an electrical connection device includes a connection terminal for applying a power line, and an exemplary view of FIG. 1 shows an outlet and a plug as part of a conventional electrical connection device.

In the outlet shown in FIG. 1A, a connection terminal 2 is embedded in the case body 1, and the connection terminal includes a connection port 3 connected to the wire 5.

Outside (upward) of the case body 1, a connecting groove 4 is formed in order to hold the plug connection of the electric appliance in the connecting terminal 2 which is the arm of the outlet.

On the other hand, as shown in Fig. 1B, the plug has a case body 1 to be seated in the connecting groove 4, and a male part for being connected to the connection terminal, i.e., inscribed in the case body 1; The connection terminal 2 as shown in FIG.

The electric wire 5 of the electric appliance is connected to the connection terminal 2, and electricity is supplied from the outlet to the electric appliance through the plug.

However, there is a problem that it is difficult to connect the electric wire to the connection terminal of such a connection mechanism.

In other words, the connecting device is a power supply device, and the wire is connected to the power supply device. To connect the wires, the tool is dismantled by using a tool, the cover of the wire is removed, and then the tool is connected again. Connect the connection terminal and the wire by using, and the assembly must be completed in the reverse order.

For this reason, there may be related to the present invention, for example, plugs which are connected to electric wires by simple operation in Application Nos. 20-1984-0010740, 20-1985-0016926, 20-1997-0001525, 20-2002-0015495 BACKGROUND ART Electrical connection mechanisms such as outlets are known.

However, there is a problem that the wire connection device of such a conventional electrical connection mechanism does not have sufficient conditions for connection.

This condition is based on the fact that, first, the connection should be made by simple operation, and the wires should be completely concealed inside the case while separating the wires so that short circuits do not occur, and in particular, by means of a cover for providing a device for safety connection after assembly. Terminals should be protected from exposure and minimal exposure of the connecting device is required.

Second, disassembly and assembly of the case for simple operation and fastening of screws, etc. should be excluded, and an integrated case for operation should be provided, and the dismantling of wires should be excluded.

And, thirdly, the locking means must be provided so that the electric wire does not escape from the connection terminal after the connection, but it is not provided as a connection device that satisfies all these conditions.

That is, Application No. 20-1984-0010740 (Plug) has a risk of short circuit due to insufficient induction of electric wires, and the cover can be concealed by removing and assembling a separate cover. .

Application No. 20-1985-0016926 (wire connection device) is inconvenient to use a tool such as a driver, and the arrangement of the wires are arranged in the same direction as the connection terminal (the direction of the tension force of the wire) to remove the disconnected wires There is a problem that is not sufficiently prevented.

Application No. 20-1997-0001525 (Plug plug for connecting wires without stripping the cover) has a problem that the cover and the case body are separated, and the locking means for sufficiently fixing the wires is insufficient to prevent the disconnection of the connected wires. have.

Application No. 20-2002-0015495 (outlet) has to use a separate fixing screw and a driver, and to cover the protective cover in order to prevent an electric shock due to the exposure of the fixing screw, locking is also sufficient There is a problem that can not be performed.

As a result, the electric wire connection device of the conventional electrical connection device satisfies some conditions, and thus does not dismantle the coating, but there is a possibility of improvement such as using a separate screw or a screwdriver or a lack of locking means to mount the cover. will be.

Therefore, the present invention was devised to improve the above problems, but the connection is performed by simple operation, but the disassembly and assembly of the case, the fastening work such as screws, and the sheathing of the wire are excluded, and the wire is separated from the connecting terminal after connection. It is an object of the present invention to provide a wire connection device of an electrical connection device provided with sufficient locking means.

According to the present invention, a connection panel 10 extending to the connection terminal 2 of the electrical connection mechanism and electrically connected at all times is installed on the case body 14 which is separated by the partition 12 and extended to the connection panel 10. A connection blade 20 penetrates the sheath 16 of the electric wire 5 and is connected to the spiral 18, and a press cover 22 is provided to penetrate the electric wire sheath 16 of the connection blade 20. A pressing stand 24 is hinged to the case body 14 to press the wire 5 to the connecting blade 20 to the pressing cover 22, and is connected to the connecting panel 10 in close proximity to the connecting panel 10. An induction cradle 26 through which the wire 5 is mounted is formed together with an end of the blade 20, and the pressure cover 22 is alternately disposed with the induction cradle 26 to connect the electric wire with the connection blade 20. At the same time, it is characterized in that the pressure fixing rod 28 is formed by bending the wire 5 to perform the binding to the case body 14. A wire connecting device for the electrical connection mechanism.

Here, the connection blade 20 is formed in the direction of shearing the wire 5, when the spiral 18 of the wire 5 is a single wire, the connection blade 20 is inserted into the wire 5 is mounted While the tapered mounting portion 40 and the tapered cut portion 42 is formed in one unit across the electric wire, the lower end of the tapered cut portion 42 is the width to cut the sheath 16 in contact with the spiral Characterized in having a.

Here, in the connection blade 20, when the spirals 18 of the electric wire 5 are assembled into a plurality of stranded wires, the connection blade 20 penetrates the wires in the connection panel and is in surface contact with the stranded wires. It characterized in that formed in the connecting panel in the same direction as the arrangement direction of the stranded wire having a 30).

Here, the pressing stand 24 or guide cradle 26 or the pressing fixture 28 is provided with a mounting groove 32 to interfere with the outer periphery of the wire 5 to prevent the side deviation of the wire to prevent the right and left flow It features.

 Here, the fastening cover 22 is formed with a fastener 34 to be coupled to the case body 14, the case body 14 is characterized in that the fastening hole 36 is fastened to the fastener 34 is formed. .

As described above, the present invention connects an electric wire to an electrical connection mechanism of an outlet or a plug by a simple operation without dismantling the sheath 16 of the electric wire 5, and securely fixes the connected electric wire to the electrical connection mechanism. Provides a wire connection device for an electrical connector.

The present invention for this purpose, first, the connection panel 10 is formed by extending to the connection terminal 2 of the electrical connection mechanism.

The connection panel 10 is always electrically connected to the connection terminal, the connection panel 10 is applied to the shape of the connection portion differently depending on the shape of the connection terminal 2 of the electrical connection mechanism.

That is, since the connection terminal 2 of the outlet can be formed integrally with the connection panel extending therein, the connection terminal 2 of the plug is formed with an insertion portion inserted therein so that it can be formed integrally with the connection panel, The connection panel 10 is formed in the shape of a connection terminal of an electrical connection mechanism of an outlet, a plug, or a switch.

The connection blade 20 is formed in the connection panel 10 to be connected to the electric wire, which may be formed by bending the connection panel 10, and forming an end portion thereof sharply.

As the connection blades 20 are formed in the connection panel 10, when they are integrally formed with the connection terminals in the illustrated outlet, it may be difficult to penetrate the coating due to ductility of the same material. It can be formed separately from stainless steel.

In addition, for this reason, it is also possible to separately provide the connection panel 10 and the connection blade 20 to be fastened to each other, in which case it is sufficient if only the connection blade is provided with a superior material rigidity.

The connection blade 20 is largely divided into two embodiments according to the type of wire, one of which is the case in which the spiral 18 without the wire covering is a single wire in one copper wire, and the other is the multiple spiral 18. This is the case of twisted pairs of copper wires.

The disconnection is excellent in electrical conductivity, but the ductility is not enough, the portability is reduced, whereby a fixed wiring is used, the twisted wire is not superior to the disconnection, but provides sufficient ductility to various electrical appliances or portable plugs Used wire.

According to the type of the electric wire, the connection blade 20 has a different arrangement and shape, and in the case of a single wire, the connection blade 20 is provided to be connected to the spiral 18 on both sides while cutting the electric wire in a shearing direction that crosses the electric wire ( 4a).

To this end, the connection blade 20 has a tapered shape of the upper and lower narrow shafts for mounting the wire in the shear direction of the wire, and a lower portion of the connection blade 20 contacts the spiral 18 by cutting the sheath 16 of the wire. Will have

On the other hand, in the case of stranded strands in which several copper wires are collected, it is difficult to apply a single stranded connection blade immediately in order to be connected to the spiral, which means that when the connecting blade penetrates the sheath of the wire in the shear direction of the wire, This is because the copper wire is cut and it cannot be guaranteed that the cut copper wire and neighboring copper wires are sufficiently connected to the connection blades.

Therefore, it is preferable to adopt a method of penetrating the sheath of the stranded wire and contacting the side surface of the connection blade 20 without cutting the stranded wire. Accordingly, in the present invention, the direction of the connection blade is arranged in the same direction as the wiring direction. (See FIG. 4B).

In addition, the sharpening point 30 is provided above the connection blade 20 so that the connection blade 20 can easily penetrate the coating of the electric wire.

The connection panel 10 including the connection blades 20 is embedded in the case body 14 and is electrically isolated by the partition wall 12.

The case body 14 extends integrally with the conventional one to accommodate the connection panel, and the pressing cover 22 is provided for the operation of connecting the wires 5 to the connection panel 10 above the extended case body 14. It is installed.

The pressing cover 22 generates a pressing force by hand operation for the wire connection, and is hinged to the case body 14 via a hinge shaft 38 for generating the pressing force by the lever force.

And the pressing stand 24 which presses the electric wire 5 is formed in the bottom part of this press cover 22. As shown in FIG.

The pressing table 24 is disposed to cross the connection blade 20 on the side so as not to interfere with the connection blade 20, the mounting groove 32 is formed to prevent the left and right flow of the wire for pressing to the right position It is.

Here, the pressure to the home position means a pressure for pressing the mounted wire downward, which is more necessary in the case of stranded wire.

That is, in the case of a single wire, the mounting means for mounting the wire 5 is provided to the connection blade 20, so that the path can be maintained sufficiently in the pressing direction. Since it is not there, it is necessary for the pressing table 24 to carry out this in order to hold the downward pressure direction.

Accordingly, when the user mounts the wire 5 on the connection blade 20 and presses the compression cover 22, the user presses the wire on which the compression table 24 is mounted downward, and the connection blade 20 covers the covering. If broken, it penetrates and is connected to the spiral. In particular, in the case of a stranded wire, the mounting groove 32 of the compression zone maintains a downward movement path to assist the penetration into the coating 16.

On the other hand, only the connection of the connection blade 20 and the wire 5 is not enough to retain the fastening force between the wire and the electrical connection mechanism.

In this case, when a tension force that pulls the wires 5 is applied, the wires may be separated from the outlet or plug.

In order to prevent this, it is necessary to impart a fastening force between the electric wire and the electrical connection device itself, and the present invention is provided with a separate locking means.

The locking means is achieved by bending the wire 5 from the case body 14 with respect to the tension direction of the wire 5 to add a resistive force to the tensile force. For this purpose, the locking means 20 is adjacent to the connection panel 10. Induction cradle (26) through which the wire (5) is mounted is formed with the end of the), and the pressing cover (22) is interlocked with the induction cradle (26) to fix the wire (5) to the case body (14). At the same time as the connection of the wire to the connection panel and the bending of the wire (5) to perform the binding to the case body is formed to intersect the guide cradle (26).

In addition, the pressing fixture 28 and the guide bracket 26 is formed with a mounting groove 32 to prevent the side separation of the wire (5).

Therefore, when the pressing cover 22 is pressed, the wires are bent up and down alternately by the guide cradle 26 and the pressure fixing stand 28, and this bending is sufficient resistance to the tension direction against the separation of the wires into the case body. To grant.

On the other hand, the pressing cover 22 and the case body 14, the fastener 34 and the fastening hole 36 is formed to open the cover for fixing or replacing the electric wire after the operation is completed.

Therefore, the user opens the pressure cover 22 and then mounts the wires on the guide cradle 26 and the connection blades 20 and presses the pressure cover 22 to close the wires 5 by the pressure rods 24. In addition to being connected to and electrically connected to the connection blade 20, the wires are deformed by the guide bracket 26 and the pressure fixing stand 28, whereby the wires are sufficiently fixed to the electrical connection mechanism.

As described above, according to the present invention, by forming a connection blade connected to the connection terminal of the electrical connection mechanism and by pressing the pressure cover with a pressing cover on the case body, the effect of being connected to the wire without dismantling the coating by simple operation There is.

In addition, the case body and the pressing cover is provided with a means for locking the electric wire so that it is operated in conjunction with the connection of the wire, the wire is sufficiently secured to the case body when the wire is connected has the effect of preventing the departure.
