Abstract

A vehicle-side connector ( 10 ) is provided for connection to a battery mounted in a vehicle. The vehicle-side connector ( 10 ) includes a housing ( 20 ) configured so that a charging connector ( 90 ) is connected thereto. Vehicle-side terminals ( 40 ) individually are accommodated in cavities ( 28 ) in the housing ( 20 ) and are configured to be connected individually to charging terminals ( 93 ) in the charging connector ( 90 ) when the housing ( 20 ) and a charging connector ( 90 ) are connected. A retainer ( 50 ) is configured to retain the vehicle-side terminals ( 40 ) in the cavities ( 28 ). A resistance circuit unit ( 70 ) is assembled into the retainer ( 50 ) and has a relay terminal ( 73 ) arranged on a left side connected to a vehicle-side signal terminal ( 40 B) and a relay terminal ( 73 ) arranged on a right side is connected to a vehicle-side ground terminal ( 40 C) out of the vehicle-side terminals ( 40 ).

First claim

The invention claimed is:

1. A vehicle-side connector to be connected to a battery mounted in a vehicle, comprising:
a housing configured such that a charging connector is connected thereto;
a plurality of vehicle-side terminals individually accommodated into a plurality of cavities provided in the housing and configured to be individually connected to a plurality of charging terminals provided in the charging connector when the housing and the charging connector are connected;
a retainer configured to retain the vehicle-side terminals accommodated in the cavities; and
a relay circuit unit assembled into the retainer and having one end connected to one of the plurality of vehicle-side terminals and the other end connected to the vehicle-side terminal different from that connected to the one end out of the plurality of vehicle-side terminals,
wherein:
the relay circuit unit includes an electronic component with a pair of leads, a first relay terminal press-fittable into the retainer and to be connected to one of the leads in the electronic component and a second relay terminal press-fittable into the retainer and to be connected to the other lead in the electronic component; and
the leads are pressed by the retainer to be respectively connected to lead connecting portions provided on the first and second relay terminals when the first and second relay terminals are press-fitted.

2. The vehicle-side connector according to claim 1 , wherein the lead connecting portion includes a pair of pressure contact blades to be brought into pressure contact with the lead pushed by being pressed by the retainer.

3. The vehicle-side connector according to claim 1 , wherein:
the retainer includes holding grooves into which the vehicle-side terminals are mounted and held when the vehicle-side terminals are inserted into the cavities;
the first and second relay terminals include a terminal connecting portion projecting into the holding groove and resiliently displaceable; and
the vehicle-side terminal is pressed against the terminal connecting portion in a mounting direction when the vehicle-side terminal is mounted and held into the holding groove.

4. The vehicle-side connector according to claim 3 , wherein:
the first and second relay terminals include a press-fit portion to be press-fitted into the retainer; and
the terminal connecting portion is bent and folded in a press-fitting direction of the press-fit portion after extending in a direction opposite to the press-fitting direction from an end part on a side opposite to the press-fitting direction.

5. The vehicle-side connector according to claim 4 , wherein an end part of the lead connecting portion on a side opposite to the press-fitting direction covers the terminal connecting portion.

6. The vehicle-side connector according to claim 2 , wherein:
the electronic component is a resistor;
the vehicle-side terminal to be connected to the first relay terminal is a vehicle-side ground terminal; and
the vehicle-side terminal to be connected to the second relay terminal is a vehicle-side signal terminal.

7. The vehicle-side connector according to claim 1 , wherein the first and second relay terminals are identically shaped.
