Electrical connector
View Patent ↗The invention relates to an electrical connector having a plurality of contact housings and a lock housing. The plurality of contact housings are vertically positioned upon each other. Each contact housing having a first end, a second end, and a step portion disposed between the first end and the second end. The lock housing includes a cover plate extending across an upper side of the plurality of contact housings and a lock arm extending from the cover plate and engageable with at least one of the plurality of contact housings. The lock arm includes an end portion engageable with the step portion.
1. An electrical connector comprising:
a plurality of contact housings vertically positioned upon each other, each contact housing having a first end, a second end, a step portion disposed there between; and
a lock housing comprising:
a cover plate extending across an upper side of the plurality of contact housings and having a pair of outer protruding bars disposed along a major surface thereof and an inner protruding bar extending upward from the major surface and positioned between the pair of outer protruding bars;
an elastic locking member extending parallel with the major surface and positioned on a rear end portion of the inner protruding bar; and
a lock arm extending from the cover plate and engageable with at least one of the plurality of contact housings and having an end portion engageable with the step portion.
2. The electrical connector according to claim 1 , wherein one of the plurality of contact housings includes a housing protrusion disposed on a first side along a rear end portion thereof.
3. The electrical connector according to claim 2 , wherein the lock arm further includes an engaging protrusion disposed along an inner surface thereof and engageable with the housing protrusion.
4. The electrical connector according to claim 1 , wherein the elastic locking member includes a locking catch disposed on an upper surface thereof.
5. The electrical connector according to claim 1 , wherein the lock arm includes a base portion extending downward from the cover plate and a tip extending from the base portion.
6. The electrical connector according to claim 5 , wherein the tip is elastically deformable in a direction orthogonal to a side of the plurality of contact housings.
7. The electrical connector according to claim 1 , wherein each contact housing includes a recess disposed on a lower surface thereof.
8. The electrical connector according to claim 7 , wherein each contact housing further includes a protrusion disposed on an upper surface thereof and corresponding with the recess of an adjacent contact housing.
9. The electrical connector according to claim 1 , wherein a width of the first end is greater than a width of the second end.
10. The electrical connector according to claim 9 , wherein the width of the lock housing is greater than the width of the second end.
