Abstract

An electronic-component-equipped terminal block includes a terminal block including first and second through holes provided in a front wall; an electronic component including a component body first and second leads; and an electrically insulating attachment assistance tool. The attachment assistance tool includes a base portion arranged outside a housing such that a rear surface thereof abuts against the front wall; and first and second insertion portions protruding from the rear surface of the base portion to be thereby inserted into the first and second through hole, respectively. The attachment assistance tool is provided with a first passage portion through which the first lead is inserted, and a second passage portion through which the second lead is inserted, and a receiving portion that receives and accommodates a rear portion of the component body is provided at a front-side position.

First claim

The invention claimed is:

1. An electronic-component-equipped terminal block comprising:
a terminal block;
an electronic component attached to the terminal block; and
an electrically insulating attachment assistance tool interposed between the electronic component and the terminal block, wherein
the terminal block includes:
a housing having, in a front wall thereof, a first through hole and a second through hole provided to reach an accommodating portion formed inside the housing;
a first terminal portion arranged in the accommodating portion so as to face the first through hole; and
a second terminal portion arranged in the accommodating portion so as to face the second through hole,

the electronic component includes:
a component body arranged outside the housing so as to face the front wall;
a first lead inserted through the first through hole and connected to the first terminal portion; and
a second lead inserted through the second through hole and connected to the second terminal portion,

the electrically insulating attachment assistance tool includes:
a base portion arranged outside the housing such that a rear surface thereof abuts against the front wall and a part thereof faces the first through hole and the second through hole;
a first insertion portion protruding from the rear surface of the base portion to be thereby inserted into the first through hole; and
a second insertion portion protruding from the rear surface of the base portion to be thereby inserted into the second through hole,

a first passage portion through which the first lead is inserted is provided to extend from the base portion to the first insertion portion,
a second passage portion through which the second lead is inserted is provided to extend from the base portion to the second insertion portion, and
a receiving portion that receives and accommodates at least a rear portion of the component body is provided at a front-side position of the base portion.

2. The electronic-component-equipped terminal block according to claim 1 , wherein
the first passage portion has a first guide portion having a passage cross-sectional area that decreases with increasing distance from the base portion, to thereby guide the first lead to the first terminal portion, and
the second passage portion has a second guide portion having a passage cross-sectional area that decreases with increasing distance from the base portion, to thereby guide the second lead to the second terminal portion.

3. The electronic-component-equipped terminal block according to claim 1 , wherein
the base portion is provided with a first frame-like portion that surrounds at least a part of the first passage portion when viewed from the front side,
the base portion is provided with a second frame-like portion that surrounds at least a part of the second passage portion when viewed from the front side, and
each of a rear surface of the first frame-like portion and a rear surface of the second frame-like portion abuts against the front wall.

4. The electronic-component-equipped terminal block according to claim 1 , wherein
the receiving portion is located at least between the first passage portion and the second passage portion.

5. The electronic-component-equipped terminal block according to claim 4 , wherein
the base portion has a pair of erected wall portions that face each other in a direction orthogonal to a direction connecting the first passage portion and the second passage portion, when viewed from a front side, and
the receiving portion is defined by the pair of erected wall portions.

6. The electronic-component-equipped terminal block according to claim 5 , wherein
the base portion is not located between the pair of erected wall portions, when viewed from the front side.

7. An electronic device comprising an electronic-component-equipped terminal block comprising:
a terminal block;
an electronic component attached to the terminal block; and
an electrically insulating attachment assistance tool interposed between the electronic component and the terminal block, wherein
the terminal block includes:
a housing having, in a front wall thereof, a first through hole and a second through hole provided to reach an accommodating portion formed inside the housing;
a first terminal portion arranged in the accommodating portion so as to face the first through hole; and
a second terminal portion arranged in the accommodating portion so as to face the second through hole,

the electronic component includes:
a component body arranged outside the housing so as to face the front wall;
a first lead inserted through the first through hole and connected to the first terminal portion; and
a second lead inserted through the second through hole and connected to the second terminal portion,

the electrically insulating attachment assistance tool includes:
a base portion arranged outside the housing such that a rear surface thereof abuts against the front wall and a part thereof faces the first through hole and the second through hole;
a first insertion portion protruding from the rear surface of the base portion to be thereby inserted into the first through hole; and
a second insertion portion protruding from the rear surface of the base portion to be thereby inserted into the second through hole,

a first passage portion through which the first lead is inserted is provided to extend from the base portion to the first insertion portion,
a second passage portion through which the second lead is inserted is provided to extend from the base portion to the second insertion portion, and
a receiving portion that receives and accommodates at least a rear portion of the component body is provided at a front-side position of the base portion.

8. The electronic device according to claim 7 , wherein:
the first passage portion has a first guide portion having a passage cross-sectional area that decreases with increasing distance from the base portion, to thereby guide the first lead to the first terminal portion, and
the second passage portion has a second guide portion having a passage cross-sectional area that decreases with increasing distance from the base portion, to thereby guide the second lead to the second terminal portion.

9. The electronic device according to claim 7 , wherein:
the base portion is provided with a first frame-like portion that surrounds at least a part of the first passage portion when viewed from the front side,
the base portion is provided with a second frame-like portion that surrounds at least a part of the second passage portion when viewed from the front side, and
each of a rear surface of the first frame-like portion and a rear surface of the second frame-like portion abuts against the front wall.

10. The electronic device according to claim 7 , wherein:
the receiving portion is located at least between the first passage portion and the second passage portion.

11. The electronic device according to claim 10 , wherein:
the base portion has a pair of erected wall portions that face each other in a direction orthogonal to a direction connecting the first passage portion and the second passage portion, when viewed from a front side, and
the receiving portion is defined by the pair of erected wall portions.

12. The electronic device according to claim 11 , wherein:
the base portion is not located between the pair of erected wall portions, when viewed from the front side.

13. An attachment assistance tool for an electronic component configured to be interposed between an electronic component attached to a terminal block and the terminal
