Connector including separation wall with gap between opposing faces for supressing excessive impedance drop
In connectors including a housing having a separation wall, an impedance of a portion of a terminal in close proximity to the separation wall is suppressed from dropping excessively. Housings of the connector include a separation wall positioned between adjacent terminals. The separation wall includes a one-side opposing face and an other-side opposing face. Furthermore, the separation wall is formed between the one-side opposing face and the other-side opposing face, and includes a gap portion positioned between the adjacent terminals.
1 . A connector comprising a plurality of terminals and a housing, wherein:
the housing includes a separation wall positioned between adjacent of the terminals;
the separation wall includes
a one-side opposing face that opposes one of the adjacent terminals,
an other-side opposing face that opposes the other of the adjacent terminals, and
a gap portion formed between the one-side opposing face and the other-side opposing face;
wherein air or a member having a lower permittivity than the housing is disposed in the gap portion, and no member having a higher permittivity than the housing is disposed in the gap portion.
2 . The connector of claim 1 , wherein:
the terminals each include a restricted portion;
the one-side opposing face includes a one-side restricting face that restricts one of adjacent of the restricted portions from moving in a direction approaching the other thereof;
the other-side opposing face includes an other-side restricting face that restricts the other adjacent restricted portion from moving in a direction approaching the one thereof; and
the restricted portion includes a contact portion configured to contact a connection target.
3 . The connector of claim 2 , wherein:
the contact portion includes
a first contact portion, and
a second contact portion positioned further to a far side than the first contact portion in a connection direction of the connection target; and
the gap portion is positioned between adjacent of the first contact portions and is positioned between adjacent of the second contact portions.
4 . The connector of claim 3 , wherein a portion of the gap portion positioned between the adjacent first contact portions and a portion of the gap portion positioned between the adjacent second contact portions are coupled together in the connection direction.
5 . The connector of claim 2 , wherein:
each of the plurality of terminals includes a resilient support portion that resiliently supports the contact portion; and
the separation wall is configured so as to be interposed between adjacent of the resilient support portions.
6 . The connector of claim 5 , wherein:
the separation wall includes either
a one-side separated face that is a face facing a side of one of the adjacent resilient support portions and that is formed at a position separated from the one adjacent resilient support portion further than the one-side restricting face in an adjacency direction of the adjacent resilient support portions, or
an other-side separated face that is a face facing toward a side of the other adjacent resilient support portion and that is formed at a position separated from the other adjacent resilient support portion further than the other-side restricting face in the adjacency direction of the adjacent resilient support portions, or
both thereof.
7 . The connector of claim 6 , wherein:
the one-side separated face or the other-side separated face provided to the separation wall includes a near-side separated face formed at a position displaced from a position of the one-side restricting face or the other-side restricting face in an opposite direction to a contact direction in which the contact portion contacts the connection target.
8 . The connector of claim 6 , wherein:
the one-side separated face or the other-side separated face provided to the separation wall includes a first far-side separated face formed at a position displaced from a position of the one-side restricting face or the other-side restricting face toward a far side in a connection direction of the connection target.
9 . The connector of claim 6 , wherein:
the one-side separated face or the other-side separated face provided to the separation wall includes a second far-side separated face formed at a position that is displaced from a position of the one-side restricting face or the other-side restricting face in an opposite direction to a contact direction in which the contact portion contacts the connection target and toward a far side in the connection direction of the connection target.
10 . The connector of claim 2 , wherein:
the contact portion includes
a first contact portion, and
a second contact portion positioned further to a far side than the first contact portion in a connection direction of the connection target;
each of the plurality of terminals includes a resilient support portion that resiliently supports the contact portion;
the separation wall is configured so as to be interposed between adjacent of the resilient support portions;
the separation wall includes either
a one-side separated face that is a face facing a side of one of adjacent of the resilient support portions and that is formed at a position separated from the one adjacent resilient support portion further than the one-side restricting face in an adjacency direction of the adjacent resilient support portions, or
an other-side separated face that is a face facing toward a side of the other adjacent resilient support portion and that is formed at a position separated from the other adjacent resilient support portion further than the other-side restricting face in the adjacency direction of the adjacent resilient support portions, or
both thereof; and
the one-side separated face or the other-side separated face provided to the separation wall includes
a near-side separated face formed at a position displaced from a position of the one-side restricting face or the other-side restricting face in an opposite direction to a contact direction in which the contact portion contacts the connection target,
a first far-side separated face formed at a position displaced from a position of the one-side restricting face or the other-side restricting face toward a far side in a connection direction of the connection target, and
a second far-side separated face formed at a position that is displaced from a position of the one-side restricting face or the other-side restricting face in an opposite direction to the contact direction in which the contact portion contacts the connection target and toward a far side in the connection direction of the connection target.
11 . The connector of claim 1 , wherein:
the terminals each include a first contact element and a second contact element;
the first contact element includes a first contact portion and a first resilient support portion that resiliently supports the first contact portion; and
the second contact element includes a second contact portion positioned further to a far side than the first contact portion in a connection direction of a connection target and a second resilient support portion that resiliently supports the second contact portion.
