Description

[Detailed description of the invention] This invention relates to a connector.

As a conventional cable, there is a flat cable 3 in which flat conductors 1 are arranged in parallel and covered with an insulating member 2, as shown in Fig. 1.A pair of these cables 3 are electrically and mechanically connected to each other. A metal plate 4 shown in FIG. 2 was used. This metal plate 4 has a plurality of claws 4c and 4d protruding from one side of both side pieces 4a and 4b.
These side pieces 4a, 4b can be pressed and bent in the direction in which the claws 4c, 4d protrude. The connection procedure is as shown in FIGS. 3 and 4, by overlapping the end faces of both flat cables 3, 3' with each other, and connecting the opposite conductors 1, 1 of both flat cables 3, 3'. By drilling a plate insertion hole 5 through the plate insertion hole 5, inserting the metal plate 4 into each of the plate insertion holes 5, and pressing and bending both side pieces 4a and 4b, both claws 4c and 4d can be bent. Both flat cables 3, 3' are mechanically and electrically connected by this metal plate 4, which is cut into the conductors 1, 1', respectively. However, both flat cables 3,
Since the cables 3' are connected in an overlapping manner, the thickness of the cable connection portion increases, and the carpet laid thereon rises up, detracting from its aesthetic appearance.

Therefore, without increasing the thickness of the cables 3, 3'
Metal plates 6, 7 shown in FIGS. 5 and 6 have been proposed to which the metal plates 6 and 7 can be connected. That is, the metal plate 6 has bent pieces 6 at both ends of one side of the flat body 6a.
b, 6c are connected and protruding claws 6d, 6e are provided.The connection procedure is as shown in FIG. Drill insertion holes 8, 8' in the metal plate 6, insert the double bent pieces 6b, 6c of the metal plate 6 into the insertion holes 8, 8' from below, and press and bend them toward the flat plate-like main body 6a. Accordingly, each claw 6d, 6
e into each conductor of both flat cables 3, 3' to mechanically and electrically connect both cables 3, 3'. Further, the metal plate 7 shown in FIG. 6 has bent pieces 7b, 7c connected to one end and the other end of one side of a flat plate-like main body 7a, and claws 7d, 7e protrudingly provided, as shown in FIG. So, both cables 3,
3' are arranged in a T-shape, and by inserting and bending the bent pieces 7b and 7c into the respective insertion holes 9 and 9', the claws 7d and 7e bite into the respective conductors of both cables 3 and 3'. Then both cables 3, 3' are mechanically and electrically connected. However, if these metal plates 6 and 7 are used, the end faces of both flat cables 3 and 3' can be butted and connected.
There is an advantage that the thickness of the cable connection part can be reduced, but as shown in Fig. 7, both cables 3, 3'
Another problem arose in that different metal plates 6 and 7 had to be prepared depending on whether they were to be connected straight or in a T-shape as shown in FIG.

In addition, in both the conventional example and the proposed example above,
Both cables 3, 3' have insertion holes 5, 8, 8', 9,
Since the hole 9' must be drilled, the connection work becomes complicated and a special tool for drilling the hole is required.

Note that the metal plate 6 in FIGS. 5 and 6,
At step 7, when the bent pieces 6b, 6c, 7b, 7c are separated from the flat main bodies 6a, 7a, both a straight connection and a T-shaped connection can be made. However, since the claws 6d, 6e, 7d, and 7e are simply dug into, the connection strength is insufficient. As another conventional example, instead of the claws 6d, 6e, 7d, and 7e, the flat body and the bent piece are connected by fitting the claws and the holes (Japanese Patent Laid-Open No. 161382/1982). )
Another proposal has been made in which a claw is passed through a flat cable and the tip thereof is bent (Japanese Patent Application Laid-open No. 65381/1983). However, even in these cases, if the flat main body and the folded piece for pressing are separated so that they can be used for both a straight connection and a T-shaped connection, the bonding strength between the two is insufficient.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a connector that can reduce the thickness of the cable connection part, can be commonly used for straight and T-shaped connections, is easy to connect, and can be connected firmly.

An embodiment of the present invention will be described with reference to FIGS. 9 to 14. That is, as shown in FIG. 9, this connector consists of a board metal fitting 10 made of a conductive member and a pair of connecting metal fittings 11, 11'.
The board metal fitting 10 has protrusions 13 and 13' for penetrating the conductor protruding from both ends of a flat main body 12, and protrusions 14 and 14' around the protrusions. In this case, the protrusions 13, 13' are connected to the vertical cylinder parts 13a, 13'a protruding from the main body 12, and the vertical cylinder parts 13a, 13'a.
The sharp tip convex portion 13b, 1 fitted to the cylindrical end of 3′a
3'b, and by strongly pressing the tips of the protrusions 13b, 13'b downward, the protrusions 13b, 1
The entire portion 3'b can be pushed into the vertical tube portions 13a, 13'a. On the other hand, the connecting fittings 11, 11' have a vertical cylindrical part 13a,
A cylindrical convex push-in body 1 that can be freely inserted into 13'a
6, 16' are provided protrudingly, and the protrusion pushing body 1
Cutting and raised claws 17, 17' are provided around 6, 16'.

In the connection procedure, as shown in FIGS. 10 and 11, a board metal fitting 10 is placed below the connection of a pair of flat cables 3, 3' with their end faces butted against each other, and both cables 3, 3' are connected. The conductor 1 is pressed downward and both protrusions 13, 13' correspond to each other.
Both cables 3 and 3' are passed through the cable 1'. Next, as shown in FIGS. 12 and 13, the tips of the protrusions 13b, 13'b are inserted into the cylindrical ends of the protrusion pushing bodies 16, 16' of the coupling fittings 11, 11', and the coupling fittings 11, 11' is strongly pressed downward, as shown in FIG.
are forcibly pushed into the vertical cylindrical parts 13a, 13'a, and the convex pushing bodies 16, 16' are pushed into the vertical cylindrical parts 13.
a, 13'a, and the connecting fitting 1
By pushing in 1 and 11', each cutting claw 14,
17 and 14', 17' penetrate into the insulating members 2, 2' and bite into the conductors 1, 1',
Both main bodies 12, 15 and 12, 15' clamp both sides of the flat cables 3, 3'. Although FIG. 14 shows the connected state of one of the connecting fittings 11 and the board fitting 10, the connection between the other connecting fitting 11' and the board fitting 10 is also the same. In this way, both cables 3, 3' are machined by clamping both sides of both cables 3, 3' between the main body 12 of the board metal fitting 10 that spans the cable connection part and the main bodies 15, 15' of the connecting metal fittings 11, 11'. At the same time, both cut and raised claws 17, 14, protrusion 13 → main body 12 → protrusion 1
3', both conductors 1, 1' are electrically connected via both cut and raised claws 17', 14'.

When both flat cables 3, 3' are connected in a T-shape as shown in FIG. 8, they are mechanically and electrically connected using both metal fittings 10, 11, 11' in the same manner as described above.

In this way, both cables 3, 3' can be connected by butting together without overlapping them using the metal fittings 10, 11, 11', which reduces the thickness of the cable connection part and prevents the carpet laid on top of it from lifting up. . Also, these two metal fittings 10, 11, 1
1' can be used in common when both cables 3 and 3' are connected in a straight manner or in a T-shaped connection. Moreover, both cables 3,
3' from below, and push the protrusions 13b, 13'b into the vertical cylindrical parts 13a, 13'a with the protrusion pushers 16, 16' of the connecting fittings 11, 11' to remove the protrusions 16, 13'b from below. Both cables 3, 3' can be connected mechanically and electrically by simply fitting the cables 16' into the vertical cylinder parts 13a, 13'a, and the insertion holes 5, 8, 8',
9, 9' (FIGS. 3, 7, and 8) are not required at all, making the connection work easier and eliminating the need for special tools for drilling holes. Moreover, the protrusion push-in bodies 16, 16' fit into the vertical cylinder parts 13a, 13'a, and both the main bodies 12, 15 and 12, 15'
This clamps both cables 3, 3' on both sides, and the cut-and-raise claws 14, 17 and 14', 17' bite into both cables 3, 3', making both cables 3, 3' strong and stable. Can be connected.

Note that the raised claws 14, 17, 14', 17' are not necessarily necessary, and the raised claws 14, 17, 1
Even without the cables 4', 17', the mechanical connection between the two cables 3, 3' can be sufficiently achieved by the clamping of the main bodies 12, 15 and 12', 15', and the electrical connection can be made using the conductors 1, 1' on the protrusions. This is accomplished by penetrating the

As described above, the connector of the present invention is a connector that butts and connects a pair of flat cables each having a flat conductor covered with an insulating member, and has a vertical tube part at both ends of a flat board metal fitting body. a board metal fitting having a protrusion formed of a sharp convex portion which can be pushed into the part and whose tip is press-fitted so that the flat conductor portions of the pair of flat cables are respectively pierced through the protrusion; Each of the flat connector bodies is provided with a convex pusher that can be press-fitted into the vertical tube, and the convex pusher pushes each of the sharp protrusions into the vertical tube. Since a pair of connectors are press-fitted and sandwich each of the flat cables between the connector main body and the board metal fitting main body, the thickness of the cable connection portion can be reduced. In particular, it has a structure that includes a board metal fitting and a connecting tool separated from the board metal fitting, and connects the two by press-fitting the vertical cylinder part of the board metal fitting and the convex pusher of the connecting tool, and sandwiches the flat cable. It is said that Therefore, it can be used both when connecting a pair of flat cables in a straight line and in a T-shape. Although the board metal fittings and the connector are separate, they are connected by the vertical cylinder part and the convex pusher press-fitted therein, so that a reliable connection can be achieved. In addition, since the vertical tube part is press-fitted with a sharp protrusion at the tip in a protruding state,
This has the effect of making it easier to penetrate the flat cable.
