Abstract

Provided are a terminal table and a terminal table unit allowing a plurality of busbars to be connected certainly and easily with reactor busbars of reactor securing members that are connected with reactors included in reactor units having an error. A sensor terminal table 30 includes a plurality of sensor busbars 40 and a sensor-attached holding body holding the plurality of sensor busbars 40 . The sensor busbars 40 each include a reactor-side connection portion 40 a on the bottom side in a height direction H and a top connection portion 40 b on the top side in the height direction H. The reactor-side connection portion 40 a is connectable with a reactor re, and the top connection portion 40 b is connectable with an IPM or a fuel cell FC. At least one of the plurality of sensor busbars 40 is a movable busbar 41 or 43 attached to the sensor-attached holding body 31 so as to be movable in the height direction H with respect to the sensor-attached holding body 31 . The movable busbar 41 or 43 has the reactor-side connection portion 40 a connectable with the reactor re.

First claim

What is claimed is:

1. A terminal module, comprising:
a plurality of busbars each including a one-side connection portion provided on one side and connected with a first connection target and an other-side connection portion provided on the other side and connected with another connection target; and
a holding body holding the plurality of busbars;
wherein:
at least one of the plurality of busbars is a movable busbar attached to the holding body so as to be movable in a first direction with respect to the holding body, the one-side connection portion of the movable busbar being connectable with the first connection target,
the other-side connection portion is a connection through-hole allowing a connection jig to be inserted therethrough, and
the connection through-hole of the movable busbar is an elongated hole that is elongated in the first direction and runs through the movable busbar in a third direction different from the first direction and the second direction.

2. A terminal module according to claim 1 , wherein:
another busbar among the plurality of busbars is a secured busbar attached to the holding body so as not to be movable, and
the secured busbar includes an arm portion on the one side, the arm portion extending in a second direction crossing the first direction, being bendable in the first direction, and including the one-side connection portion at a tip thereof.

3. A terminal module according to claim 2 , wherein the one-side connection portion of the movable busbar and the one-side connection portion of the secured busbar are connected with the first connection target to form a circuit.

4. A terminal module according to claim 1 , wherein the holding body includes a current sensor measuring an electric current flowing in the busbar.

5. A terminal module unit, comprising:
a terminal module according to claim 1 ; and
a through-terminal module including a plurality of through-busbars extending in a first direction and a through-busbar holding body holding the plurality of through-busbars;
wherein:
the plurality of through-busbars each include a through-piece inserted through the through-busbar holding body, and a through-busbar arm portion provided on one side with respect to the through-piece, the through-busbar arm portion extending in a second direction different from the first direction and being bendable in the first direction, and
the through-piece includes an other-side connection portion on the other side, and the through-busbar arm portion includes a one-side connection portion at a tip thereof.

6. The terminal module unit according to claim 5 , wherein:
the through-piece includes a protrusion rib protruding in a thickness direction, the protrusion rib being provided so as to be in a through-hole that is formed in the through-busbar holding body and allows the through-piece to be inserted therethrough, and
the through-hole has a protrusion portion protruding inward from an inner surface thereof.

7. The terminal module unit according to claim 5 , further comprising a to-be-connected terminal module including to-be-connected portions connected with the other-side connection portions of the busbars and the other-side connection portions of the through-busbars, and also including a connection busbar conductively connecting the to-be-connected portions and another connection target to each other.

8. The terminal module unit according to claim 7 , wherein:
the through-terminal module is located on one side with respect to the terminal module, and the to-be-connected terminal module is located on the other side with respect to the terminal module, and
the holding body of the terminal module has first-direction through-holes respectively allowing the through-pieces of the through-busbars to be inserted therethrough in the first direction.

9. A terminal module unit, comprising:
a terminal module comprising
a plurality of busbars each including a one-side connection portion provided on one side and connected with a first connection target and an other-side connection portion provided on the other side and connected with another connection target, and
a holding body holding the plurality of busbars;

wherein at least one of the plurality of busbars is a movable busbar attached to the holding body so as to be movable in a first direction with respect to the holding body, the one-side connection portion of the movable busbar being connectable with the first connection target; and
a through-terminal module including a plurality of through-busbars extending in a first direction and a through-busbar holding body holding the plurality of through-busbars;
wherein:
the plurality of through-busbars each include a through-piece inserted through the through-busbar holding body, and a through-busbar arm portion provided on one side with respect to the through-piece, the through-busbar arm portion extending in a second direction different from the first direction and being bendable in the first direction, and
the through-piece includes an other-side connection portion on the other side, and the through-busbar arm portion includes a one-side connection portion at a tip thereof.

10. The terminal module unit according to claim 9 , wherein:
the through-piece includes a protrusion rib protruding in a thickness direction, the protrusion rib being provided so as to be in a through-hole that is formed in the through-busbar holding body and allows the through-piece to be inserted therethrough, and
the through-hole has a protrusion portion protruding inward from an inner surface thereof.

11. The terminal module unit according to claim 9 , further comprising a to-be-connected terminal module including to-be-connected portions connected with the other-side connection portions of the busbars and the other-side connection portions of the through-busbars, and also including a connection busbar conductively connecting the to-be-connected portions and another connection target to each other.

12. The terminal module unit according to claim 11 , wherein:
the through-terminal module is located on one side with respect to the terminal module, and the to-be-connected terminal module is located on the other side with respect to the terminal module, and
the holding body of the terminal module has first-direction through-holes respectively allowing the through-pieces of the through-busbars to be inserted therethrough in the first direction.
