BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a connector according to an embodiment of the present invention; FIG.

[0006] Reference numeral 1 denotes a flat cable used for a signal transmission device for a steering mechanism of an automobile, for example.
The flat cable 1 is formed by enclosing a plurality of conductive wires 2 in a thin plate shape with a resin coating 1c. The flat cable 1
Exposes the conductor 2 connected to each terminal 3c, 3d, 3e, 3f, 3g, 3h from the end. 1a and 1b
Is a hole for inserting a mold pin 4 formed in the vicinity of the conducting wire 2. The holes 1a and 1b are formed at the ends of the resin coating 1c of the flat cable 1. Each conductor 2 is connected to each terminal 3c, 3d, 3e, 3f, 3 by spot welding means.
g and 3h are connected.

As shown in FIG. 1, the conductive plate 3 is a single metal plate formed by pressing a band-shaped metal material 3k. The metal material 3k is made of each of the terminals 3c, 3d, 3e, 3f,
3g, 3h, outer shell 3 surrounding the connecting part 3i
By punching j, the conductive plate 3 is formed. The conductive plate 3
Are connected portions 3i and terminals 3c, 3d, 3e, 3f,
3g and 3h. Each terminal 3c, 3d, 3
The terminals e and 3f, the terminals 3g and 3c, and the terminals 3f and 3h are connected by connecting portions. After the terminals 3c, 3d, 3e, 3f, 3g, and 3h are formed by molding the connector body 5 with resin,
It is divided by punching i.

[0008] 3a is a terminal 3c, 3d, 3e, and 3f
And a first group of terminals protruding from the front surface of the connector main body 5 at equal intervals in a horizontal row.

[0009] 3b, the second consisting of the terminal 3g, and 3h
Terminal group. The terminals 3g and 3 of the second terminal group 3b
h has an L-shape formed at both ends of the first terminal group 3a as shown in FIG. The second terminal group 3b protrudes from the side surface of the connector body 5 for a length L1, bends, and folds the bent portions into the grooves 5b and 5c. Then, they are arranged in line facing the first terminal group 3a. As shown in FIG. 3, the length L1 of the second terminal group 3b protruding from the side surface of the connector 5 is the vertical length L2 of the grooves 5b and 5c,
Assuming that the horizontal lengths L3 of b and 5c are L3, L1 = L
2 + L3. As shown in FIG. 4, the bent second terminal group 3b is arranged at a position where the terminal 3g is opposed to the terminal 3c, and is arranged at a position where the terminal 3h is opposed to the terminal 3f.

As shown in FIGS. 1 and 2, the connector body 5 positions the flat cable 1 in the dies 6 and 7 by inserting the pins 4 into the holes 1a and 1b. , And 7, the first and second terminal groups 3a, 3b
A resin material is poured into and sandwiched between the conductive plate 3 having a flat cable 1 and the flat cable 1 to form the connector body 5. Pin 4
When the connector body 5 is molded, after the positioning of the flat cable 1 is completed, the flat cable 1 is removed from the molds 6 and 7.
As a result, the resin material of the connector body 5 flows into the holes 1a and 1b of the flat cable 1. FIG. 3 is a perspective view showing a state of the connector main body 5 after molding. A first terminal group 3a protrudes from the front of the connector body 5,
The second terminal group 3b protrudes from the side surface.

Reference numeral 5a denotes a punched hole into which a punch (not shown) for cutting the connecting portion 3i of the conductive plate 3 is inserted.
The grooves 5b and 5c are formed by bending the terminals 3g and 3h protruding from the side surface of the connector main body 5 so that when the terminals 3g and 3h are clamped and tightened to the connector main body 5, they have substantially the same thickness as the terminals 3g and 3h. . And Thus, a groove 5b, and 5c, and punching holes 5 a is die 6, and by pouring resin into the 7 connector
The molding is performed simultaneously with the molding of the main body 5 .

Reference numeral 6 denotes an upper mold. 7 is a lower mold. The mating connector 8 includes a connection portion (not shown) connected to the first terminal group 3a and the second terminal group 3b in the female portion 8a. The connector main body 5 includes:
And the second terminal group 3a, 3b to the female part of the mating connector 8.
8a to make electrical connection.

When a third or fourth terminal group is further formed on the connector main body 5, a third terminal group is formed outside or on both sides of the second terminal group 3b of the conductive plate 3. In this case, the connector may be protruded from the side surface of the connector main body 5, bent in the same manner as the second terminal group 3 b, and held and crimped to the connector main body 5.

The present invention in accordance connector structure is configured as described above, are given below by way processing steps like.

[0015] First, as shown in FIG. 1, to expose the conductors 2 from the end of the flat cable 1, drilling holes 1a to the site of the flat cable 1, and 1b in the vicinity of the conductor line 2. The outer portion 3j of the metal material 3k is punched, and each terminal 3
The conductive plate 3 in which c, 3d, 3e, 3f, 3g, and 3h are continuously provided at the connecting portion 3i is formed. Each terminal 3 is connected to each conductor 2
Spot welding is performed to connect the base ends of c, 3d, 3e, 3f, 3g, and 3h. At this time, each terminal 3c, 3
Since d, 3e, 3f, 3g, and 3h are made of one conductive plate 3, positioning and spot welding work are easy.

[0016] Then, as shown in FIG. 2, the hole 1a flat cable 1, and insert the pin 4 in 1b, and the flat cable 1 is positioned in the mold 6, and 7. Mold 6,
And 7 sandwich the flat cable 1 and the conductive plate 3 having the first and second terminal groups, and pull out the pins 4 from the flat cable 1 and the molds 6 and 7. A resin material is injected into the molds 6 and 7 to form the connector main body 5 shown in FIG. Since the flat cable 1 is formed with the holes 1a and 1b, the flat cable 1 can be accurately and easily positioned on the molds 6 and 7 with the pins 4. The resin material of the connector body 5 is the flat cable 1
Flows into the holes 1a and 1b and solidifies, so that the flat cable 1 is firmly fixed to the connector body 5. Thus, when the connector body 5 is formed, the pins 4 supporting the flat cable 1 do not remain in the resin material of the connector body 5.

Next, from the state shown in FIG. 3, by cutting the coupling portion 3i located in the punching hole 5a of the connector body 5, six terminals 3c, 3d, 3e, 3f, 3g, and 3h between each other of Divide.

Next, as shown in FIG. 4, the connector body 5
Bend the terminals 3g and 3h projecting from the side of
It is immersed in the grooves 5b and 5c. As a result, the first terminal group 3a and the second terminal group 3
b, that is, the terminals 3c, 3d, 3e, 3f, and 3h are arranged to face each other. 2 rows of terminals 3 of connector body 5
c, 3d, 3e, 3f, 3g, and 3h are formed by press-forming one conductive plate 3, and the number of parts is small, and the cost can be reduced. The second terminal group 3b, the groove 5b of the connector body 5, and then immersed in 5c, since there is no dead Zhang <br/> Rukoto from the surface site of the connector body 5, the connector body 5 mating connector 8
Can be properly fitted.
