CN-122000712-A - Connector with a plurality of connectors

Abstract

The connector is formed into a row in which a plurality of groove connection portions for connecting the respective wires are arranged in the lateral direction (x), and the plurality of rows are overlapped in the vertical direction (z), and when at least one empty groove connection portion for not connecting the wires is present in any one of the rows, when a virtual line passing through the center of the vertical direction (z) of the respective rows in parallel with the respective rows is determined, and the center of each row on the virtual line is set as the center of 180-degree rotational symmetry, the wires are not connected to the groove connection portions in the other rows in the respective rows at positions of 180-degree rotational symmetry with respect to the empty groove connection portions in any one of the rows. According to the present invention, even in the double-row connector, the difficulty in pulling out can be reduced, and disconnection of the electric wire can be prevented.

Description

Connector with a plurality of connectors Technical Field The present invention relates to a connector in which a plurality of connection portions are arranged in two rows. Background In the electric connector, a plurality of wire receiving recesses for receiving and holding the respective wires are arranged, and a plurality of insertion holes for receiving and holding the respective post terminals (terminal pins) are arranged, the respective wire receiving recesses and the respective insertion holes are combined one by one and are adjacent to each other, for each set of wire receiving recesses and insertion holes, contacts penetrating the wire receiving recesses and the insertion holes are provided, and the wires of the wire receiving recesses and the post terminals of the insertion holes are connected by the contacts. Further, as the connector, there is a double-row connector, for example, configured such that two of the above-described electrical connectors are overlapped one above the other. Disclosure of Invention Here, for example, the image forming apparatus may be divided into a plurality of models according to differences in color devices, monochrome devices, production PPM, and the like, and even if the number of components such as motors, sensors, and the like is different between models, a substrate common design may be performed for each model, and a common connector may be used for each model. In this case, although the non-mounted component is generated according to the model, since the electrical connection of the non-mounted component is not required, the electric wire of the component connected to the terminal pin on the substrate side is removed from the connector. That is, the electric wires (called empty pins) of the component that is not mounted among the electric wires on the connector side connected to the terminal pins on the substrate side are omitted. However, when a plurality of wires in the connector are removed and the wires are gathered at one side of the connector, when the connector is pulled out, the force applied to the connector is uneven, the pulling out becomes difficult, and disconnection of the wires may occur. In particular, in the double-row type connector as described above, since the number of wires and terminal pins is significantly increased, the force required to remove the connector for each terminal pin becomes larger, and when a plurality of removed wires are gathered on one side of the connector, the difficulty level of removal and the breakage rate of the wires become higher. The present invention has been made in view of the above circumstances, and an object thereof is to reduce difficulty in disconnection and prevent disconnection of a wire even in a double-row connector. As an aspect of the present invention, a technique that further improves the above technique is proposed. A connector according to an aspect of the present invention is a connector in which a plurality of first connection portions are arranged in a row in one direction, two of the rows are arranged parallel to each other and overlap each other in a direction orthogonal to the one direction, an electric wire is connected to each of the plurality of first connection portions, and when an empty first connection portion to which at least one of the electric wires is not connected is present in any one of the rows, when a virtual line passing through the center between the columns in parallel with the columns is determined, when a position on the virtual line that is the center of the columns in the one direction is set to be a center of 180 degrees rotational symmetry, the electric wire is not connected to the first connection portion in the other columns in the columns at the 180 degrees rotational symmetry position with respect to the empty first connection portion in the any one column. According to the present invention, even in the double-row connector, the difficulty in pulling out can be reduced, and disconnection of the electric wire can be prevented.
