Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrical connector that is fixed to the end of an electric wire and screwed to a terminal plate to make an electrical connection.

A conventional electrical connector 1 has the shape shown in FIG.

That is, an electrical connection part 3 is extended and connected to one side of a disc-shaped electrical contact part 2 having a one-shape shape, and an electric wire 4 is fixed to the electric wire connection part 3.

When a plurality of electrical connectors 1 are stacked and fixed, the electrical contact portions 2, 2' are overlapped as shown in FIG. 1, and screws 5 are inserted into the top and bottom to screw them onto the bus bar.

However, in this configuration, the electric contact portions 2, 2' are flat and thinner than the electric wires 4, 4';
It is not possible to fix the wires 4, 4' in the same direction, and as shown in FIG. 1, the wires 4 and 4' must be spread apart at an angle and then fixed with screws.

For this reason, if a large number of busbars are installed close together,
The wiring was messy and it was inconvenient to assemble.

In view of the above drawbacks, the present invention provides an electrical connector that can be stacked and fixed with the wires fixed to each electrical connector oriented in the same direction.

An embodiment of the present invention will be described below with reference to the drawings.

The electrical connector 6 is formed from a thin steel plate by pressing the ends of the electrical contact portion 7 and the wire connection portion 8.

The electrical contact portion 7 is fabricated by folding a thin plate from both sides, and a conductor insertion hole 9 such as a screw or pin is opened in the vertical direction in the center.

A cylindrical spacer 10 is protruded around the conductor insertion opening 9, and the height of the spacer 10 is slightly larger than the outer diameter of the electric wire, which will be described later.

The wire connecting portion 8 has a plate shape, and crimp clamping portions 11 and 12 protruding from both sides thereof for the conductor portion and insulating coating portion of the wire.

The insulating coating of the electric wire 13 is crimped and fixed by the crimp holding part 12, and the conductor 14 exposed at the end of the electric wire 13 is crimped and fixed by the crimping holding part 11.

Next, the operation of this embodiment will be explained.

Figure 3 shows the state in which two electrical connectors 6, 6' are assembled with screws 15. Electrical connectors 6, 6' are assembled with the wires 13, 13' fixed to each facing in the same direction. On the upper surface of the spacer 10 of 6 is an electrical connector 6'.
The back surfaces of the electrical contact portions T' of the two are opposed to each other.

Then, the screw 15 is inserted into the conductor insertion opening 9, 9' of each electrical connector 6, 6'.

FIG. 4 shows the state in which the electrical connectors 6.about.6' are screwed and fixed to the connector box 16.

A metal terminal plate, that is, a bus bar 17 is projected from one side of the connector box 16, and the bus bar 17 is provided with a fixed opening 18.

Insert the lower end of the screw 15 inserted into the electrical connectors 6, 6' as described above into the fixed opening 18, and insert the Nand 1 into the lower end of the screw 15.
9, and electrical connector 6. ff and the bus bar 17 from above and below, and connect the electrical connectors 6, 6 to the bus bar 17.
′ is fixed.

Spacer 10.10'+2 wires 13.13' each
Since the outer diameter of the wires 13 and 13' is larger than that of the wires 13 and 13', the wires 13 and 13' can be stacked in a layered manner without contacting each other even if the wires 13 and 13' are oriented in the same direction.

In this embodiment, the spacers 75 to 75 constructed as described above may be formed into a truncated conical shape, and the outer wall and inner wall of each spacer may be brought into close contact with each other.

Further, mutual rotation can be prevented by providing a projection on the upper end of the spacer and fitting it into another electrical connector.

Since the present invention is constructed as described above, the electric wires fixed to each electrical connector can be fixed in a stacked manner facing the same direction, and the electric wires will not be cluttered during the connection work, making it possible to assemble them in an orderly manner.
