Abstract

An electrical connection structure between a module device and an external device having high reliability of electrical connection and excellent assembling performance. The electrical connection structure a module device includes a module housing accommodating the module device having a mounting hole for mounting a cable connector electrically connected with an external device, a contact of the module device side disposed inside the module housing positioned in the mounting hole, the structure includes a terminal pressed and connected to the contact of the module device side, and a connector housing that accommodates and holds the terminal, the terminal is held in the connector housing so as to have airtight and watertight properties from a connection portion between the terminal and a core wire of a cable to a covering portion of the cable, and the cable connector and the housing are connected so as to have the watertight property.

Claims

1. An electrical connection structure between a module device and an external device comprising:

a module housing accommodating the module device having a mounting hole for mounting a cable connector electrically connected with the external device; and

a contact of the module device disposed inside the module housing positioned in the mounting hole,

wherein, the electrical connection structure includes a terminal configured to connect to the contact of the module device, and a connector housing that accommodates and holds the terminal, and

wherein, the terminal is held in the connector housing so as to have airtight and watertight properties from a connection portion between the terminal and a core wire of a cable to a covering portion of the cable, wherein the connection portion and the housing are connected so as to have the watertight property.

2. The electrical connection structure between a module device and an external device according to claim 1,

wherein, the terminal is accommodated in the connector housing in a state in which the core wire of the cable is connected to the rear portion of the terminal, and

wherein, portions from the connection portion between the terminal and the core wire of the cable to the covering portion of the cable are embedded in a sealant.

3. The electrical connection structure between a module device and an external device according to claim 2,

wherein, the sealant is connected to the cable using a cord bushing, and

wherein, the cord bushing and the housing are fixedly connected with a fixing member via a seal member.

4. The electrical connection structure between a module device and an external device according to claim 3,

wherein, a retainer for supporting the terminal from the rear is disposed in the connector housing and in a state of accommodating the terminal.
