Abstract

This disclosure aims to provide a technique with which the waterproofness of a connector can be enhanced. The molded connector includes: a first terminal unit that includes a first connector terminal and a first holder that holds the first connector terminal; a second terminal unit that includes a second connector terminal and a second holder that holds the second connector terminal, and is stacked on the first terminal unit; a first wire connected to the first connector terminal; a second wire connected to the second connector terminal; and a connector housing formed through insert molding, using the first terminal unit, the second terminal unit, an end portion of the first wire, and an end portion of the second wire as insert parts.

First claim

The invention claimed is:

1 . A molded connector comprising:
a first terminal unit that includes a first connector terminal and a first holder that holds the first connector terminal; a second terminal unit that includes a second connector terminal and a second holder that holds the second connector terminal, and is stacked on the first terminal unit; a first wire connected to the first connector terminal; a second wire connected to the second connector terminal; and a connector housing configured to receive the first terminal unit, the second terminal unit, an end portion of the first wire, and an end portion of the second wire, the molded connector further comprising a first sheath covering the first wire and a second sheath covering the second wire, wherein the connector housing covers an end portion of the first sheath and the second sheath, a first protruding portion extending from a first protruding surface of the base body portion of the first holder which covers a portion of a first contact portion of the first connector terminal protruding from the first protruding surface, a second protruding portion extending from a second protruding surface of the base body portion of the second holder which covers a portion of a second contact portion of the second connector terminal protruding from the second protruding surface, and the connector housing includes a portion covering the first protruding portion and the second protruding portion and facing the first protruding face and the second protruding face.

2 . The molded connector according to claim 1 ,
wherein the first terminal unit is formed by subjecting the first holder to insert molding using the first connector terminal as an insert part, and the second terminal unit is formed by subjecting the second holder to insert molding using the second connector terminal as an insert part.

3 . The molded connector according to claim 2 ,
wherein a first wire connecting portion of the first connector terminal that is connected to the first wire protrudes outward of the first holder, and a second wire connecting portion of the second connector terminal that is connected to the second wire protrudes outward of the second holder, and the connector housing covers a connection portion between the first wire and the first wire connecting portion and a connection portion between the second wire and the second wire connecting portion.

4 . The molded connector according to claim 3 ,
wherein the first wire connecting portion includes a first bottom plate connected to a core wire of the first wire, the second wire connecting portion includes a second bottom plate connected to a core wire of the second wire, and the first bottom plate and the second bottom plate are present between the core wire of the first wire and the core wire of the second wire.

5 . The molded connector according to claim 1 , wherein a portion of the connector housing that covers the first holder and the second holder is provided with a hole recessed in a direction in which the first terminal unit and the second terminal unit are stacked on each other.

6 . The molded connector according to claim 1 , wherein the first holder and the second holder are each provided with a locking portion for positioning the first terminal unit and the second terminal unit in a direction intersecting a direction in which the first terminal unit and the second terminal unit are stacked on each other.

7 . The molded connector according to claim 1 , further comprising:
a third terminal unit that includes a third connector terminal and a third holder that holds the third connector terminal, and is stacked between the first terminal unit and the second terminal unit; and a third wire connected to the third connector terminal; wherein the third terminal unit and an end portion of the third wire are the insert parts of the connector housing.
