 Fig. 2, an exploded perspective view of an integrated socket perspective view of the integrated socket and branch device of the present invention, an integrated socket and a branch in the ceiling wiring distributor, and a socket and a branch of another embodiment of the ceiling wiring distributor of the integrated socket and the branch device of the present invention. 4 is a perspective view of the device, another embodiment of the branching device of the present invention integrated socket and branch device, which is not inserted into the resin in the ceiling wiring distributor of the integrated socket and branch device of FIG. Looking at Figure 6, which is a seating coupling groove of the middle portion of the branch line and a combination perspective thereof and FIG. 7 is a seating coupling groove of the end of the branch line and the coupling perspective view thereof in another embodiment of the present invention integrated socket and the splitter for the ceiling wiring of the branch device,

The ceiling wiring distributor is composed of a lower case 22 and an upper case 23 for each distributor, and the lower case 22 and the upper case 23 are combined to form a case 21.

In the ceiling wiring distributor, the socket 24 into which the connection terminals to which the power line is connected is inserted is placed in the connection port 26 inside the front end of the case 21. The socket 24 may be a socket or a male as necessary. The socket is seated.

The female groove of the cowcket and the male projection of the male socket are configured at regular intervals so as to correspond to each other, and the ceiling wiring distributor having a cowcket and the ceiling wiring distributor having a male socket are the male protrusions of the female socket of the female socket. Is inserted into the distributor.

Typically, the quadrant divider 20 into which the power is inserted is inserted into four sockets one by one in four directions, which are inserted into the case in four directions, and the three divider is inserted into the case. Three sockets are inserted in three directions one by one to branch the incoming power in three directions, and the two divider divides the sockets that are inserted into the case into two directions one by one in two directions. The and reducers branch into one direction by inserting one socket.

The ceiling wiring divider is divided into a socket and a male socket because the distributor is coupled to one distributor and the combination of the distributors is a socket.

 The socket 24 of the present invention, which is assembled in various ceiling wiring distributors, is not composed of an upper socket, a lower socket or an all socket, and a rear socket, and is configured as a single body.

 As the socket 24 and the socket 24 are connected, all the sockets 24 are integrally formed by injection molding of a synthetic resin, and the connection between the sockets 24 and the sockets 24 is possible by the connection bar 27 or the like. .

In other words, all the sockets 24 and the connection bar 27 are injection molded into a synthetic resin integrally at a time.

The connection bar 27 is configured on the outer end side of the portion of the socket 24 where the connection terminal 29 of the branch device 25 is grounded, and the connection terminal 29 of the other adjacent socket 24 is grounded. It is connected to the outer end side of the portion to be configured so that the socket 24 is formed integrally.

When the adjacent sockets 24 are connected to each other as the connection bar 27 in all the sockets 24, all the sockets 24 are integrally formed, and when the sockets 24 are formed, the female sockets have female recesses ( In this male socket, a male groove is formed.

The connecting bar 27 may be configured to be inserted into the case 21 but may be configured as one, and may be configured as two but spaced apart from each other. The connecting terminal 29 of the branch device 25 in the socket 24 may be configured. ) May be configured on the bottom surface of the outer end of the grounded portion.

 In addition, as the branch device 25 is placed, the entire bottom surface of the portion formed as a space between the socket 24 and the socket 24 may be configured as an integrated connection bar for integrally connecting the socket 24 and the socket 24. .

In other words, the branch device is configured on the integrated connecting bar.

Therefore, since the socket is composed of a single body, there is no gap in the socket body, so that sparks generated when connecting or disconnecting the power supply terminal do not affect the connecting terminal on the side, and the connecting bar fixes the socket and the socket so that all sockets are integrated. The distance between the socket and the socket is constant.

The branching device 25 is built into the case 21 and is coupled to four sockets that are geometrically corresponding to each connection port 26 of the case 21. The connecting terminal 29 is coupled to the tip of the branch line 30 while the branch line tip is bundled.

Meanwhile, six female recesses 28 having a predetermined interval are integrally formed in the cowcket according to the number of connecting pins of the inlet or outlet lines, that is, the branch line tip, and the female recesses 28 are through holes penetrating the inside of the socket. It is composed.

A connecting terminal 29 for connecting with a male terminal connection terminal is formed in the through hole of the female recessed groove 28 of the socket. One connecting terminal 29 is inserted in one through hole.

 All six wires of the power introduced into the ceiling wiring distributor are distributed in four directions of the cowcket in the branch device 25, where the same branch wire 30 is inserted into the same through hole of all the sockets.

For example, in the case of a grounding wire, the grounding holes are grounded to the through holes of the first left socket of all the branching devices 25, and in the case of the midline, the grounding holes are grounded to the through holes of the second left socket of all the branch devices 25.

This is because the arrangement of the branching lines to be inserted should be the same so that it is possible to know which branching line of which through-hole is which line, thereby reducing the defects caused by the wiring in the electrical wiring.

On the other hand, the external power supply to the branch device 25 may be supplied to the branch device 25 by the connection of the power supply side socket, it may be made by the lower power supply through the outlet of the lower case.

In general, the latter power supply method is used. In this case, in order to supply external power into the branch device 25, a configuration in which the external power line is connected is configured in the branch device 25.

The connection configuration of the external power is composed of a power supply terminal 31 which is connected to the external power at the tip of the connection pin, that is, the branch line 30, to which one socket is connected in the branch device 25, and this power connection terminal 31 When the external power line is connected to the external power is supplied to the branch device (25).

 The connecting terminal 29 is formed at the tip of the branch line 30, but the terminal of the branch line 30 for connecting the external power source has a power connecting terminal 31 at the end of the connecting terminal 29 on the side of the branch line 30. It is comprised adjacent to (29).

 The socket 24 on the front end side of the branch line 30 in which the power connection terminal 31 is configured is directly connected to the supplied power, and the remaining sockets 24 are supplied with power by distribution of the branch line 30.

The socket 24 and the branching device 25 are integrally formed, and the connection terminal 29 of the branching device 25 is insert-molded in the socket 24.

The branch line 30 is insert-molded in the synthetic resin 32, the power connection terminal 31 is exposed to the outside of the synthetic resin 32, it is possible to connect to the power supply line is supplied only when the power connection terminal 31 is exposed to the outside of the synthetic resin. Because.

While the socket 24 and the branch line 30 are injection molded as a single piece of the synthetic resin 32, the branch line 30 is insert molded into the synthetic resin 32 and the power connection terminal 31 is exposed to the outside of the synthetic resin 32. Since the synthetic resin 32 is filled between the branch line 30 and the branch line 30, there is no flow of the branch line 30 and the branch line 30 is reliably insulated.

Looking at the step of injection molding the socket 24 and the branch line 30 into a single piece of synthetic resin 32,

The branching device combined with the connection terminal and the power connection terminal on the branch line is placed in the filling room in the stationary mold, but the power connection terminal is placed outside the filling room, and the movable mold approaches the stationary mold, In order to determine the relative position with the filling chamber, a fixing pin operated by an air cylinder by pneumatic pressure is inserted into the filling chamber from the outside of the mold to fix the branching device at the center of the filling chamber, and then the molten resin injected from the molding machine nozzle into the filling chamber. As it flows and fills the filling chamber of the mold, a branch device is formed in the resin and a socket is formed.

When the fixing pin is discharged to the outside of the mold after the filling chamber is filled with the molten resin, the pressurizing device is further advanced to compensate for the volume reduction caused by shrinkage while cooling the synthetic resin, and the hole formed by the fixing pin is After filling that hole by

The step of solidifying the synthetic resin while cooling the mold, removes the high heat of the molten resin in the mold as cooling water, gives plasticity to the molten resin to solidify the synthetic resin, and then separate the movable mold and the fixed mold, the molded product by the eject Is separated from.

On the other hand, the branch line 30 of the branching device 25 is composed of an electric wire, the covering material of the electric wire is Teflon or asbestos that does not melt during the injection molding of the synthetic resin.

The electric wire coated with vinyl has a weak vinyl coating at high heat, and the vinyl coating is melted at a high temperature of about 200 ° C. generated during the injection molding of the integrated socket and the branching apparatus of the present invention.

In the injection molding, the vinyl coating is melted before the synthetic resin is filled in the branch line 30, and the synthetic resin is filled after the branch lines 30 are adjacent to or connected to each other. Thus, the branch device 25 to which the branch line 30 is connected is shorted. This becomes unusable.

Therefore, a Teflon or asbestos-coated electric wire that does not melt even at high temperatures during injection molding is used.

And the branch line of a branching apparatus can insert-injection-molded, without breaking | disrupting the shape of the said electrically conductive material which already took shape, using the uncoated electrically conductive material.

In this case, the same branch lines are connected to each other in the branching device 25, and the other branch lines are bypassed without causing the other branch lines to be coupled.

When branching lines having different properties, that is, non-joining branches meet, one branching line forms a bent portion 33 formed in the vertical and horizontal directions at a portion that meets the other branching line, and allows another branching line to pass under the bending portion 33. will be.

For example, the ground wires are coupled to each other, and the middle wires are also coupled to each other. When the ground wires and the middle wires intersect, they are spaced apart from each other so that any one line is bypassed upward or downward.

By forming the bent portion 33 at the branch line 30, the length of the straight branch line is reduced to increase the rigidity of the branch line 30 at the bent portion 33, and the same branch lines 35 and 36 are coupled to each other so that the volume of the branch device is increased. By shortening the straight line of the branch line while reducing the number of lines and simplifying the internal wiring, the injection molding of the branch device is possible by strengthening the binding of the combined branch lines.

At this time, in connection coupling the same branch line, the branching line (A) of the branch line (35, 36) of the branch line (35, 36) is connected to each other in the branch line (30) of the branch device (25) configured inside the distributor case (21). 35 and 36 constitute a seating coupling groove 34 in each of the branch lines 35 and 36 coupled to each other.

The seating coupling groove 34 is configured to cross the branch lines 35 and 36, the length of which is equal to the width of the branch lines 35 and 36, and the depth is formed vertically in the thickness direction of the branch lines 35 and 36. do.

The seating coupling grooves 34 are configured to correspond to each other at the branch lines 35 and 36.

For example, in the upper branch line positioned at the upper portion of the branch lines 35 and 36 to be coupled, the seating coupling groove 34 is formed at the lower surface of the branch line, and in the lower branch line positioned at the lower portion, the seating coupling groove 34 is formed at the upper branch line. To configure.

The seating coupling grooves of the upper branch line and the seating coupling grooves of the lower branch line correspond to each other so that the seating coupling grooves 34 are coupled to each other.

When combined in this way, the seating coupling groove of the upper branch line catches the lower branch line, and the seating coupling groove of the lower branch line catches the upper branch line so that the combined branch line does not deviate and withstands impact resistance without flow and does not collapse its shape during injection molding. will be.
