Description

Joint connector

The technology disclosed herein relates to a joint connector.

As an example of a conventional joint connector, the one described in Japanese Patent Application Laid-Open No. 2010-40263 (the following Patent Document 1) is known. The joint connector includes a plurality of terminals connected to a plurality of electric wires, a conductive member having a plurality of connecting portions respectively connected to the plurality of terminals, and a housing into which the terminals and the conductive member are inserted. . The housing has a plurality of first openings into which the respective terminals are inserted, and a second opening into which the conductive member is inserted.

It is done.

JP, 2010-40263, A

By the way, in connectors used in automobiles, shielded connectors are generally used, particularly when they are disposed at places where shielding against noise is required. Also in the joint connector, in addition to waterproofness, one having a shielding property with a simple configuration is required.

The technology disclosed herein has been completed based on the above circumstances, and an object of the present invention is to provide a joint connector of a novel configuration having both waterproof and shield functions. It is a thing.

A technology disclosed in the present specification includes a plurality of terminals connected to a plurality of electric wires, and a plurality of connection portions connected to the plurality of terminals, and a conductive member electrically connecting the plurality of terminals. A housing for housing the plurality of terminals and the conductive member inside; a plurality of terminal openings for covering the housing and inserting the plurality of terminals into the housing; and the conductive member A metal shield shell having a conductive member opening for insertion into a housing, a plurality of terminal-side rubber plugs for sealing the terminal opening separately and separately, and a conductive seal are made watertight It is a joint connector provided with the conductive member side rubber plug to seal, and the metallic cover which closes the opening part for conductive members from the outside of the conductive member side rubber plug.

According to the above configuration, since the housing is covered by the metal shield shell and the cover, the joint connector can be provided with shielding properties. In addition, since the terminal opening of the shield shell is sealed in a watertight manner by the terminal side rubber plug and the opening for the conductive member is sealed in a watertight manner by the conductive member side rubber plug, waterproofness inside the shield shell is ensured. ing.

Further, according to the above configuration, the housing itself is covered with the shield shell and the cover, and the opening of the shield shell is sealed in a watertight manner by the rubber plug, so that the number of parts is small and the size is small.

Moreover, conventionally, when electrically connecting a plurality of terminals at a place where shielding is required, a plurality of branched relay shield connectors are connected to a connector portion provided with a conductive member installed on the vehicle side. At the same time, the conductive member and the terminal on the electric wire side are connected by fitting a plurality of shield connectors on the electric wire side into these shield connectors for relay. For this reason, the structure is complicated and the fitting operation of the shield connectors is required at the installation site.

On the other hand, according to the above configuration, both the terminals and the conductive member can be accommodated in one housing while providing the shielding property, and the fitting operation of the connector can be omitted, so that the working efficiency is improved. . Moreover, since it can ship in the state which connected the terminal and the electrically conductive member beforehand by the connector components supply side, the fitting operation | work in an attachment site becomes unnecessary.

The joint connector may have the following configuration.

A rubber stopper may be provided on the outside of the terminal-side rubber plug for retaining the terminal-side rubber plug.

According to the above configuration, even when a force is applied to the electric wire in the direction in which the terminal is pulled out, the terminal side rubber plug is suppressed from being pulled out from the terminal opening of the shield shell. Further, the terminal side rubber plug is in contact with the rubber plug holder, whereby excessive deformation is suppressed.

A half insertion detection member may be provided between the terminal and the terminal side rubber plug for detecting a half insertion state of the terminal into the housing. According to such a configuration, the terminal can be prevented from being half inserted into the housing, and connection reliability is improved.

The half insertion detection member may be provided integrally with the terminal side rubber plug. According to such a configuration, it is possible to prevent the user from forgetting to attach the half insertion detection member. Moreover, compared with the structure which provides a half insertion detection member and a rubber plug separately, while a number of parts decreases, a work process can also be reduced.

The shape holding member which suppresses a deformation | transformation of the said terminal side rubber plug may be integrally provided in the terminal side rubber plug. According to such a configuration, when the terminal side rubber plug is fitted into the terminal opening, or when the electric wire is pulled in an oblique direction, the terminal side rubber plug is deformed and the waterproofness is not impaired. Be done.

The conductive member-side rubber plug may be provided with a vibration control protrusion that protrudes toward the conductive member and is in close contact with the conductive member. According to such a configuration, it is possible to prevent the conductive member and the terminal from sliding due to vibration of the vehicle or the like, and to be worn out. Also, connection reliability is improved.

A metal shield conductor may be provided to cover between the shield shell and the wire drawn from the shield shell. According to such a configuration, since the terminal opening is covered by the shield conductor, the shieldability of the joint connector is further improved.

Moreover, the protective cover which covers a shield conductor may be provided. According to such a configuration, for example, even in the case where the shield conductor is made of an easily hooked member such as a metal braided wire or the fixing portion of the shield conductor to the shield shell has a complicated shape, these are covered and protected. be able to.

According to the technology disclosed herein, a joint connector having both waterproof and shield functions can be obtained.
