[0002]

2. Description of the Related Art An apparatus or machine for inserting individual wires of a cable into a press-contact type contact of an electrical connector of this type (hereinafter simply referred to as a connector) is provided with a first side extending from a common side.
A row and a second row of contacts are included. The second row of contacts extends further from the common plane than the first row of contacts. The device includes a frame, a first insertion mechanism and an insertion mechanism. The first insertion mechanism includes a movable first
It has an insertion blade and inserts individual wires into the first row of contacts. The second insertion mechanism is disposed adjacent to the first insertion mechanism, has a second movable blade, and inserts an individual wire into the second row of contacts. A holder slidably coupled to the frame, moving the connector along the path in opposite directions to the right and left at predetermined intervals, temporarily aligning the first insertion blade with each contact position in the first row, and The second insertion blade is temporarily aligned with each contact position in the row.

[0003] Electrical cables, such as those used in telephones, are:
It typically includes a number of color coded wire pairs that are twisted to reduce crosstalk. A male connector is terminated at one end of a predetermined length of these cables, and a female connector is terminated at the other end. This cable is used for interconnecting various communication devices. This connector uses a press-contact type contact, inserts an insulated wire into a predetermined contact position during a termination operation, and penetrates an insulating coating to make contact between an internal conductor and the contact. See U.S. Patent No. 3,760,355 for an example. This patent publication discloses a connector having two rows of press-contact contacts. One row is arranged on one side of the connector housing and the other row is arranged on the opposite side of the connector housing.

A device for cutting a wire into a predetermined length and inserting it into a predetermined pressure contact generally has two insertion mechanisms having a connector holder and an insertion blade located on the opposite side of the holder. The holder is movable and the opposite contact pair is temporarily stopped in alignment with the two insertion blades. For example, Chandra and others on December 1, 1980
See U.S. Pat. No. 4,238,874, issued on June 6. Here, this is incorporated as a reference.

[0005] The connector holder of this device moves to the position of the first contact pair in alignment with the insertion blade. Next, the operator (operator) selects the first wire pair to be inserted and manually slides each wire along each guideway until both wires contact the sensor. At this time, the insertion mechanism is operated to move the insertion blade toward the connector, grasp the two wires, cut the wire into a predetermined length, and insert the wire into the corresponding contact.

[0006] These connectors have been increasingly miniaturized in response to technological trends in electronics, computers, communications and other related fields, and there has been an increasing demand for miniaturization of the components and interconnection devices used. To meet this goal, small connectors have been developed, with two rows of press-contacts arranged on one side of the housing. FIGS. 1 and 2 show an example of such a connector in a perspective view and a sectional view, respectively. The miniature connector 10 has a housing 12, a plug portion 14, and upper and lower contacts 20, 22 disposed in two offset rows 16, 18, respectively. Both contacts 20, 22 extend on the same side of the insulating housing 12.

0 includes leads 24 and extends downward to be interconnected to corresponding contact traces 26 on one side of plug portion 14. On the other hand, each lower contact 22 includes a lead 28 and extends downward to be interconnected to a corresponding contact trace 30 on the opposite side of plug portion 14. Each upper contact 20 is paired with a corresponding lower contact 22 and is vertically aligned with each other, such that each lead 2
4, 28 and corresponding contact traces 26, 30 are located on opposite sides of the insulating housing 12.

[0008]

The connector 10 is arranged such that a pair of wires is terminated to a pair of upper and lower contacts, one wire being located directly above the other. Since both the upper and lower contacts 20, 22 are arranged at a center-to-center spacing of about 0.79 mm (0.031 inch), the structure is extremely compact and delicate. The device of the aforementioned U.S. Pat. No. 4,328,874 cannot terminate this connector 10 unless both insertion mechanisms are changed to be on the same side. To do this, it is necessary to stack both insertion mechanisms, and both insertion blades will be vertically aligned and matched with both contact pairs 20, 22, which is impractical. is there.

Accordingly, an object of the present invention is to provide an electric connector assembling apparatus suitable for assembling a miniature connector having a plurality of press-contact type contacts arranged in two rows offset on the same side of an insulating housing, that is, for terminating wires. That is.
