This invention relates to an invention that can be connected to a terminal.

[Conventional technology]

As is well known, modular electrical connectors are often used. These connectors provide high connection efficiency because wires can be terminated simultaneously.

Of course, there are many types of electrical connectors with this modular structure, and many have been proposed, for example, in Japanese Utility Model Application Publication No. 12279/1982 and Japanese Patent Application Laid-open No. 167282/1982. Among other things, each of the upper and lower rows includes a housing of insulating material in which elongated terminal receiving cavities are formed in parallel, each cavity being defined by two spaced apart side walls, a top wall, and a bottom wall. each cavity has a pin receiving port at its forward end;
The pin receiving opening is arranged in the same configuration as the array of pins and further includes a plurality of terminals respectively attached to each of the cavities, each terminal having a pin engaging portion at its forward end and a rearward thereof. The wire engaging portion of each terminal has a wire engaging portion at the end, and the wire engaging portion of each terminal has an insulating coating that receives the insulated wire conductor and bites into the insulating coating to make electrical contact with the conductive wire. The upper row of cavities are different from the lower row of cavities, and the electrical connector is of modular construction, with an opening in each of the upper and lower row cavities. With the terminal installed in each cavity, the insulated wire conductor is inserted into each terminal through the opening of each cavity, that is, the insulation coating is inserted into the slot of the terminal to form the conductor. can be connected to the terminal.

However, in conventional connectors of this type, the cavities in the upper and lower rows are staggered, but the openings connected to the cavities are formed in opposite directions in the upper and lower rows.

That is, the upper row cavities have openings formed in the upper wall, and the terminals are arranged so that the terminal slots face upward, and the lower row cavities have openings formed in the lower wall, so that the terminal slots face upward. The terminals were arranged so that they faced downward.

[Problem to be solved by the invention]

According to the above-mentioned conventional technology, there are the following problems.

Insulated wire conductors cannot be connected to each terminal in the upper row and lower row cavities at the same time. That is, the upper row of insulated wire conductors must be connected to the terminals in the upper row of cavities, and then the lower row of insulated wire conductors must be connected to the terminals in the lower row of cavities. In short, it requires 2 connection work,
Furthermore, there is a need to improve connection efficiency.

In addition, when connecting insulated wire conductors to terminals in the upper row cavity and terminals in the lower row cavity, the wire must be inserted from the upper row side through the upper wall opening on the upper row side, and the wire must be inserted from the upper row side through the upper wall opening on the upper row side. The connection operation itself is also inconvenient because there are two insertion directions: insertion from the lower row side through the wall opening.

Therefore, it is an object of the present invention to connect insulated wire conductors to each of the terminals in the upper row and lower row cavities simultaneously in one direction, that is, only from the upper row side, more specifically, only from the top of the connector. To provide electrical connectors that can be connected. This makes it possible to increase the efficiency of the connection work, and also to allow the insulated wire conductors to pass through the slots from above the connector and connect to the slots of the terminals in the cavities of the upper and lower rows. An object of the present invention is to provide an electrical connector that allows easy connection work.
