Problems solved by technology

However, air bubbles are sometimes generated in the filler, and it is difficult to confirm the occurrence of a large number of air bubbles, and when there are a large number of air bubbles, it is difficult to ensure waterproof performance. An attempt was made to secure the waterproofness of the connecting portion between the wire and the terminal fittings by placing gaskets in the gaps between the body and the terminal fittings instead of using a filler, but this solution has the disadvantages of a large number of parts and a long assembly work time. question
In addition, even with a connector using a gasket, it is difficult to confirm whether the gasket is installed in the correct position, and if the gasket is not installed in the correct position, it is difficult to ensure waterproof performance

Abstract

The invention aims to provide a connector; the connector can prevent offset of a pipe body wrapping a connecting portion between a terminal joint and a wire, and can ensure waterproof property of the connecting portion between the terminal joint and the wire; the connector (1) comprises the following elements: the terminal joint (2) connected with an end portion of the wire (10); a housing (3) containing the wire and the terminal joint; the pipe body (4) arranged in the housing and used for wrapping the connecting portion between the terminal joint and the wire; an opening portion pressing the pipe body from an outer side; and a pressing part (5) sealing the opening portion so as to prevent the water from entering the connecting portion through the opening portion.

Description

technical field [0001] The present invention relates to a connector, which has: a terminal fitting connected to an end of an electric wire, a case for accommodating the electric wire and the terminal fitting, and a tube provided inside the case to cover the connecting portion between the terminal fitting and the electric wire. body. Background technique [0002] Cars, which are moving objects, are equipped with various electronic devices. In-vehicle wiring is used to transmit power, control signals, etc. to the electronic equipment. In-vehicle wiring has multiple wires and connectors. [0003] Conventionally, connectors have adopted a structure for securing the waterproofness of the connecting portion between the electric wire and the terminal fitting. For example, there is known a connector that ensures waterproofness of the connecting portion between the electric wire and the terminal fitting by filling the vicinity of the connecting portion between the electric wire an...
