Abstract

Certain embodiments provide a connector cover attached to a communication connector of a power supply device which includes a secondary battery and a manager. The connector cover includes a plurality of cover side terminals which are each connected to a plurality of connector side terminals, the connector side terminals are connection terminals included in the communication connector and provided on a supply circuit supplying power of the secondary battery to the manager and a cover base portion which has a first side on which the plurality of cover side terminals electrically connected by a conductive portion are positioned and a second side, and electrically connects between the plurality of connector side terminals on the supply circuit when the plurality of cover side terminals are connected to the connector side terminals and a protector which is positioned on the second side of the cover based portion.

First claim

What is claimed is:

1. A connector cover attached to a communication connector of a power supply device which includes a secondary battery and a manager managing the secondary battery, the connector cover comprising:
a plurality of cover side terminals which are each connected to a plurality of connector side terminals, the connector side terminals are connection terminals included in the communication connector and provided on a supply circuit supplying power of the secondary battery to the manager;
a cover base portion which has a first side on which the plurality of cover side terminals electrically connected by a conductive portion are positioned and a second side different from the first side, and electrically connects between the plurality of connector side terminals on the supply circuit when the plurality of cover side terminals are connected to the connector side terminals; and
a protector which is positioned on the second side of the cover based portion.

2. The connector cover according to claim 1 , wherein the protector has an attaching structure which attaches the protector to the communication connector, and
when the protector is attached to the communication connector, electrical conductivity between the connector side terminals is lowered than when the cover side terminal is connected to the connector side terminal.

3. The connector cover according to claim 1 , further comprising:
a disengagement preventer which is rotatably attached to an outer circumferential surface of the cover base portion and prevents the cover base portion from disengaging from the communication connector.

4. The connector cover according to claim 3 , wherein appearances or colors of the protector and the disengagement preventer are different from each other to be visually recognized.

5. The connector cover according to claim 1 , wherein the protector is provided with an opening screwably fastened to the communication connector in an axial direction of the cover base portion.

6. A connector cover attached to a communication connector of a power supply device which includes a secondary battery and a manager managing the secondary battery, the connector cover comprising:
a plurality of cover side terminals which are each connected to a plurality of connector side terminals, the connector side terminals are connection terminals included in the communication connector and provided on a supply circuit supplying power of the secondary battery to the manager;
a cover base portion which is provided with the plurality of cover side terminals electrically connected by a conductive portion, and electrically connects between the plurality of connector side terminals on the supply circuit when the plurality of cover side terminals are connected to the connector side terminals; and
a switcher which switches presence or absence of an electrical connection between the plurality of connector side terminals on the supply circuit.

7. The connector cover according to claim 6 , wherein the cover base portion has a first side on which the plurality of cover side terminals are positioned and a second side on an opposite side to the first side, and
the plurality of cover side terminals are positioned on the first side of the cover base portion and the switcher is positioned on the second side.

8. The connector cover according to claim 6 , wherein the switcher is subjected to a pressing operation and switches the presence or absence of the electrical connection between the plurality of connector side terminals on the supply circuit in response to the pressing operation.

9. The connector cover according to claim 6 , wherein the switcher is subjected to a rotation operation and switches the presence or absence of the electrical connection between the plurality of connector side terminals on the supply circuit in response to the rotation operation.

10. The connector cover according to claim 6 , wherein the switcher is subjected to an operation of a predetermined device existing within a predetermined range from a position of the connector cover and switches the presence or absence of the electrical connection between the plurality of connector side terminals on the supply circuit in response to the operation of the predetermined device.

11. The connector cover according to claim 10 , wherein the switcher is a magnet switch, and switches the presence or absence of the electrical connection between the plurality of connector side terminals on the supply circuit in response to a remote operation by a magnet as the predetermined device.

12. The connector cover according to claim 10 , wherein the switcher includes a communicator which is operated by the secondary battery, and switches the presence or absence of the electrical connection between the plurality of connector side terminals on the supply circuit in response to a remote operation of a communication device corresponding to the communicator as the predetermined device.

13. A connector cover attached to a communication connector of a power supply device which includes a secondary battery and a manager managing the secondary battery, the connector cover comprising:
a plurality of cover side terminals which are each connected to a plurality of connector side terminals, the connector side terminals are connection terminals included in the communication connector and provided on a supply circuit supplying power of the secondary battery to the manager;
a cover base portion which is provided with the plurality of cover side terminals electrically connected by a conductive portion, and electrically connects between the plurality of connector side terminals on the supply circuit when the plurality of cover side terminals are connected to the connector side terminals; and
an information display which is connected to the plurality of cover side terminals and displays information regarding a state of the secondary battery based on power of the secondary battery.

14. The connector cover according to claim 13 , wherein the information display includes a residual quantity display that displays a state of charge of the secondary battery.

15. The connector cover according to claim 13 , wherein the information display further includes a state display that displays a connection state of the secondary battery.

16. The connector cover according to claim 13 , further comprising:
a waterproof member which is provided at a part where the communication connector and the cover base portion are engaged with each other, and seals a gap of the engaged part.

17. The connector cover according to claim 13 , further comprising:
a disengagement preventer which is detachably provided on the communication connector and prevents the cover base portion from disengaging from the communication connector.

18. The connector cover according to claim 13 , further comprising:
a switcher which switches presence or absence of an electrical connection between a connection terminal connected to the power supply terminal and a connection terminal connected to the control terminal.

19. The connector cover according to claim 18 , wherein the switcher is subjected to at least one of a pressing operation and a rotation operation and switches the presence or absence of the electrical connection between the plurality of connector side terminals on the supply circuit in response to the operation.
