An improved rotary latch and housing configured to receive a strike is described. The housing includes two parts that are mated together to improve their resistance to impact forces imparted by the strike. The housing is provided with a channel-shaped recess for receiving the strike. A rotary jaw and rotary pawl are disposed within the housing to secure the strike in a locked position and release the strike in an unlocked position.

What is claimed is: 1. A rotary latch comprising: a housing comprising a first portion and a second portion, the first portion comprising a first lateral wall and a first transverse wall extending substantially perpendicular from the first lateral wall in a first direction, the first transverse wall having a first terminal edge and defining a first projection extending from the first terminal edge in the first direction, the second portion comprising a second lateral wall spaced apart from the first lateral wall in the first direction so as to form a gap therebetween, and a second transverse wall extending substantially perpendicular from the second lateral wall in a second direction opposite the first direction, the second transverse wall having a second terminal edge and defining a recess extending from the second terminal edge in the first direction, wherein the first projection is received in the recess with the first and second terminal edges abutting such that the first and second transverse walls bridge the gap formed between the first and second lateral walls, and wherein the first projection and the recess are shaped to form a dovetail joint; a rotary pawl disposed at least partly within the housing between the first and second lateral walls; and a rotary jaw disposed at least partly within the housing between the first and second lateral walls. 2. The rotary latch of claim 1, wherein the first projection forms a tab and the recess forms a slot adapted to receive the tab. 3. The rotary latch of claim 2, further comprising a strike, wherein the first lateral wall and the second lateral wall define a channel shaped to receive the strike. 4. The rotary latch of claim 3, wherein the rotary jaw defines a recess shaped to secure the strike in cooperation with the channel. 5. The rotary latch of claim 4, wherein the housing is formed from a rigid material. 6. The rotary latch of claim 5, wherein the rigid material is steel. 7. The rotary latch of claim 1, wherein the first projection is welded to the recess. 8. The rotary latch of claim 1, further comprising: a third transverse wall extending substantially perpendicular from the first lateral wall in the first direction, the third transverse wall having a third terminal edge and wherein the third transverse wall is spaced from the first transverse wall in a lateral direction, and a fourth transverse wall extending substantially perpendicular from the second lateral wall in the second direction, the fourth transverse wall having a fourth terminal edge and wherein the fourth transverse wall is spaced from the second transverse wall in the lateral direction, wherein the third and fourth terminal edges are abutting, and wherein one of the third and fourth transverse walls comprises a second projection extending from one of the third and fourth terminal edges; and wherein the other of the third and fourth transverse walls has a second recess defined therein and extending from the other of the third and fourth terminal edges, wherein the second projection is received in the second recess. 9. The rotary latch of claim 1, wherein the first transverse wall is secured to the second transverse wall with an adhesive. 10. A rotary latch comprising: a housing comprising a first portion, a second portion, and a central region defined therebetween, the first portion comprising a first lateral wall defining a first channel comprising a first mouth opening from a first edge of the first lateral wall in a first direction and a first transverse wall extending from the first lateral wall toward the central region, wherein the first mouth of the first channel does not intersect a plane defined by the first transverse wall, the second portion comprising a second lateral wall defining a second channel comprising a second mouth opening from a first edge of the second lateral wall in the first direction, and a second transverse wall opposed to the first transverse wall and lying in the plane, the second transverse wall extending from the second lateral wall toward the central region, wherein the second mouth of the second channel does not intersect the plane. wherein the first transverse wall is secured to the second transverse wall, wherein the first transverse wall comprises a projection and the second transverse wall comprises a recess shaped to receive the projection, wherein the projection and the recess form a dovetail joint, thereby preventing separation of the first portion relative to the second portion; a rotary pawl disposed at least partly within the housing; a unitary rotary jaw having a pair of arms defining a strike recess, said rotary jaw disposed at least partly within the housing; and a strike moveable relative to the housing in the first direction between an engaged position and disengaged position, wherein the first channel of the first lateral wall and the second channel of the second lateral wall are aligned and configured to removeably receive the strike as the strike is moved between the engaged and disengaged positions. 11. The rotary latch of claim 10, wherein the first transverse wall is welded to the second transverse wall, thereby preventing movement of the first transverse wall relative to the second transverse wall. 12. The rotary latch of claim 10, wherein the first transverse wall is secured to the second transverse wall by an adhesive, thereby preventing movement of the first transverse wall relative to the second transverse wall.
