Abstract

A connector ( 100 ) is disclosed that includes a housing ( 2 ) having a length, a width, a first end wall ( 15 ), a second end wall ( 19 ), and a plurality of first ( 17 ) and second ( 18 ) grooves disposed on upper-portion main surface and bottom-portion main surface of a base ( 2 ). The grooves receive pluralities of first ( 70 ) and second ( 71 ) insulated conductors, respectively. A plurality of terminals ( 16 ) make contact with the first and second insulated conductors so that the first insulated conductors and the second insulated conductors are electrically connected to each other.

First claim

The invention claimed is:

1. A connector that electrically connects a plurality of first insulated conductors and a plurality of second insulated conductors that correspond, wherein
the connector is provided with a housing;
the housing is provided with
a base that has a length along a first direction between a first edge portion and a second edge portion that oppose each other and a width along a second direction orthogonal to the first direction,
a first end wall and a second end wall that extend in an up-and-down direction respectively from the first edge portion and the second edge portion,
a plurality of first grooves and a plurality of second grooves that are provided in an upper-portion main surface and a bottom-portion main surface of the base that oppose each other and respectively receive the plurality of first insulated conductors and the plurality of second insulated conductors, and
a plurality of electrical contact terminals that is provided in correspondence with the first grooves and the second grooves and contacts the first insulated conductors received in the first grooves and the second insulated conductors received in the second grooves so the first insulated conductors and the second insulated conductors are electrically connected to each other; and

the housing is set with a symmetry axis, but not a symmetry plane, that is orthogonal to the first direction and the second direction.

2. The connector according to claim 1 , wherein the first end wall and the second end wall are offset from each other along the second direction.

3. The connector according to claim 1 , wherein the base has a third edge portion and a fourth edge portion that extend along the first direction between the first edge portion and the second edge portion and oppose each other;
the base is provided with
an upper-side step portion that protrudes upward from the upper-portion main surface and extends along the third edge portion and the fourth edge portion and
a lower-side step portion that protrudes downward from the bottom-portion main surface and extends along the third edge portion and the fourth edge portion; and

the upper-side step portion is provided with the first grooves and the lower-side step portion is provided with the second grooves.

4. The connector according to claim 1 , further provided with an upper-portion cover that detachably engages with a portion extending upward from the base at the first end wall and the second end wall, and
a bottom-portion cover that detachably engages with a portion extending downward from the base at the first end wall and the second end wall.

5. A connector assembly, comprising: a housing;
an upper-portion cover that is detachably assembled to an upper portion of the housing;
a plurality of first insulated conductors that is disposed between the housing and the upper-portion cover;
a bottom-portion cover that is detachably assembled to a bottom portion of the housing;
a plurality of second insulated conductors that is disposed between the housing and the bottom-portion cover; and
a plurality of electrical contact terminals that contacts the first insulated conductors and the second insulated conductors so as to electrically connect the first insulated conductors and the second insulated conductors to each other; wherein
the housing is set with a symmetry axis, but not a symmetry plane, and
the upper-portion cover and the bottom-portion cover have configurations in planar symmetry with each other with a symmetry plane set between the upper-portion cover and the bottom-portion cover as reference.

6. A connector that electrically connects a plurality of first insulated conductors and a plurality of second insulated conductors that correspond, wherein
the connector is provided with a housing;
the housing is provided with
a base that has an upper-portion main surface and a bottom-portion main surface that oppose each other,
a first upper-portion end wall and a second upper-portion end wall that extend upward from the base and oppose each other in a first opposing direction interposing the upper-portion main surface,
a first bottom-portion end wall and a second bottom-portion end wall that extend downward from the base and oppose each other in a second opposing direction interposing the bottom-portion main surface, and
a plurality of electrical contact terminals that is held by the base and contacts the first insulated conductors and the second insulated conductors so as to electrically connect the first insulated conductors and the second insulated conductors to each other;

in a situation where the upper-portion main surface is viewed downward from above,
the first upper-portion end wall and the second upper-portion end wall are in point symmetry with an upper-portion symmetry point set on the upper-portion main surface as reference, and
the first upper-portion end wall and the second upper-portion end wall respectively have a first upper-portion offset portion and a second upper-portion offset portion by being offset from each other along a direction orthogonal to the first opposing direction;

an offset amount of the first upper-portion offset portion and an offset amount of the second upper-portion offset portion are the same,
the first upper-portion offset portion and the second upper-portion offset portion being offset with one direction, clockwise or counterclockwise, relative to the upper-portion symmetry point as reference;

in a situation where the bottom-portion main surface is viewed upward from below,
the first bottom-portion end wall and the second bottom-portion end wall are in point symmetry with a bottom-portion symmetry point set on the bottom-portion main surface as reference, and
the first bottom-portion end wall and the second bottom-portion end wall respectively have a first bottom-portion offset portion and a second bottom-portion offset portion by being offset from each other along a direction orthogonal to the second opposing direction; and

an offset amount of the first bottom-portion offset portion and an offset amount of the second bottom-portion offset portion are the same,
the first bottom-portion offset portion and the second bottom-portion offset portion being offset with the other direction, clockwise or counterclockwise, relative to the bottom-portion symmetry point as reference, wherein the housing does not have a symmetry plane that is orthogonal to the first and second directions.

7. The connector according to claim 6 , wherein the first opposing direction and the second opposing direction match, the first upper-portion end wall and the first bottom-portion end wall are configured as an end wall continuous in an up-and-down direction, and the second upper-portion end wall and the second bottom-portion end wall are configured as an end wall continuous in the up-and-down direction.

8. The connector according to claim 6 , wherein further provided are an upper-portion cover that is detachably assembled to an upper portion of the housing, and
a bottom-portion cover that is detachably assembled to a bottom portion of the housing;
the upper-portion cover has a first upper-portion cover sidewall and a second upper-portion cover sidewall that oppose each other;
