Electrical connector having a short-circuiting terminal
View Patent ↗A connector includes a first housing housing a plurality of first terminals, a second housing being fittable to the first housing and housing a plurality of second terminals connectable to the respective first terminals, a short-circuiting terminal housed in the first housing and having contact pieces contacting the respective first terminals which are adjacent to each other, and a release portion provided on the second housing and displacing the contact pieces to release contact between the first terminals and the contact pieces. The second housing is deflectably provided with a lock arm on an outer peripheral surface of the second housing, the lock arm holding a state in which the first housing and the second housing are fit together. The release portion is arranged on the outer peripheral surface of the second housing forward of the lock arm in a fitting direction of the first housing and the second housing.
1. A connector comprising:
a first housing housing a plurality of first terminals;
a second housing housing a plurality of second terminals connectable to the respective first terminals, the second housing being fittable to the first housing;
a short-circuiting terminal housed in the first housing, the short-circuiting terminal having contact pieces configured to contact the respective first terminals which are adjacent to each other, the contact pieces being on a free end portion of the short-circuiting terminal facing the second housing; and
a release portion provided on the second housing, the release portion configured to displace the contact pieces to release contact between the first terminals and the contact pieces,
wherein the second housing is deflectably provided with a lock arm on an outer peripheral surface of the second housing, the lock arm configured to hold a state in which the first housing and the second housing are fit together,
wherein the release portion is arranged on the outer peripheral surface of the second housing forward of the lock arm in a direction in which the first housing and the second housing are fit together, and
wherein each of the contact pieces includes a sliding protrusion protruding in a width direction of the respective contact piece facing an adjacent contact piece of the short-circuiting terminal.
2. The connector according to claim 1 ,
wherein the first housing is provided with a short-circuiting terminal housing chamber which houses the short-circuiting terminal, and
wherein the short-circuiting terminal housing chamber is arranged to face the lock arm in the direction in which the first housing and the second housing are fit together.
3. The connector according to claim 1 , wherein the contact pieces extend towards the second housing in parallel to one another.
4. A connector comprising:
a first housing housing a plurality of first terminals;
a second housing housing a plurality of second terminals connectable to the respective first terminals, the second housing being fittable to the first housing;
a short-circuiting terminal housed in the first housing, the short-circuiting terminal having contact pieces configured to contact the respective first terminals which are adjacent to each other, the contact pieces being on a free end portion of the short-circuiting terminal facing the second housing; and
a release portion provided on the second housing, the release portion configured to displace the contact pieces to release contact between the first terminals and the contact pieces,
wherein the second housing is deflectably provided with a lock arm on an outer peripheral surface of the second housing, the lock arm configured to hold a state in which the first housing and the second housing are fit together,
wherein the release portion is arranged on the outer peripheral surface of the second housing forward of the lock arm in a direction in which the first housing and the second housing are fit together,
wherein a displacement portion is arranged on the second housing to be positioned between two contact pieces, and
wherein the two contact pieces are configured to move in a width direction away from each other as the two contact pieces move along the displacement portion.
5. A connector comprising:
a first housing housing a plurality of first terminals;
a second housing housing a plurality of second terminals connectable to the respective first terminals, the second housing being fittable to the first housing;
a short-circuiting terminal housed in the first housing, the short-circuiting terminal having contact pieces configured to contact the respective first terminals which are adjacent to each other, the contact pieces being on a free end portion of the short-circuiting terminal facing the second housing; and
a release portion provided on the second housing, the release portion configured to displace the contact pieces to release contact between the first terminals and the contact pieces,
wherein the second housing is deflectably provided with a lock arm on an outer peripheral surface of the second housing, the lock arm configured to hold a state in which the first housing and the second housing are fit together,
wherein the release portion is arranged on the outer peripheral surface of the second housing forward of the lock arm in a direction in which the first housing and the second housing are fit together,
wherein each of the contact pieces includes a sliding protrusion, the sliding protrusion configured to slide along a slope of the release portion, and
wherein the sliding protrusion is offset from a contact portion of the respective contact piece, the contact portion configured to contact the respective first terminal.
6. The connector according to claim 5 , wherein the sliding protrusion separates the contact portion from the release portion when sliding along the slope of the release portion.
