Description

  The present invention relates to a waterproof connector housing, a waterproof connector assembly, a connector waterproof structure, and a connector auxiliary member that prevent liquid such as water or oil from entering a fitting portion of a connector.

  In recent years, personal computers (hereinafter referred to as PCs) and peripheral devices have been used not only in offices but also in factories. A cable with a connector having a D-sub connector is generally used for connection between a PC and peripheral devices (for example, a barcode reader for optically reading a barcode). However, in factories where oil and water-containing mist and dust are scattered in the air, such as automobile factories, the PC and peripheral devices are connected using cables with connectors similar to those used in offices. In such a case, there is a possibility that a mist oil or the like invades into the gap between the connecting portions of the connectors to cause a problem in signal transmission / reception. For this reason, in a factory, a cable with a connector in which a connector is attached to a connector housing having a waterproof function is often used for connection with a connector attached to a panel on the PC side. For example, as a conventional configuration of a waterproof structure of a panel-mounted connector, there is one described in Patent Document 1.

On the other hand, there are many cases where peripheral devices are used at a position away from the PC installation location in the factory, and there is a case where a single cable with a connector is not enough to connect the PC and the peripheral devices. is there. In such a case, conventionally, the terminal portion of the cable connected to the PC side and the terminal portion of the cable connected to the peripheral device side are connected through a waterproof terminal box. FIG. 8 is a diagram illustrating an example of the waterproof terminal box 101. The waterproof terminal box 101 includes a box-shaped box main body 102 whose upper surface is open, and a lid 103 that closes the opening on the upper surface of the box main body 102. Both the box body 102 and the lid 103 are made of synthetic resin, and a rubber plate (not shown) as a sealing material is attached to the back surface of the lid 103. Inside the box main body 103, a terminal block 104 having a plurality of crimp terminals 105 is provided. A terminal portion of a cable connected to a PC inserted from one cable insertion port 106 and the other cable insertion port 107 are provided. Are connected individually to the respective crimp terminals 105 on the terminal block 104, respectively. Then, the lid 103 is screwed and fixed to the box body 102, so that the connection portion of both cable terminal portions is waterproofed.

  However, in the configuration in which the terminal portions of the pair of cables are connected to each other using the waterproof terminal box 101 described above, the conductive wires of the terminal portions of both cables are exposed from the covering, and each conductive wire is sandwiched between the crimp terminals 105 and individually connected. There is a problem that it takes time and effort. Further, since the conductor terminal of the cable terminal is configured to press the conductor by tightening the crimp terminal 105 with a predetermined strength so that the conductor does not come off from the crimp terminal 105, there is also a problem that the conductor is likely to be disconnected.
