Abstract

An optical transceiver which is inserted and ejected with respect to a cage in a first direction is disclosed. The optical transceiver includes a slider having a slit including a slope in a second direction intersecting in the first direction, a housing supporting the slider to slide along the first direction, and a latch having a shaft sliding in the slit lining up in the first direction in response to a projection, the projection engaging the cage and standing out from a surface of the latch in the second direction. The housing has a pair of convexes contacted both surface in each other of area between the projection and the shaft of the latch, and the pair of convexes of the housing supports the latch to slide.

Claims

1. An optical transceiver which is inserted and ejected with respect to a cage in a first direction, the optical transceiver comprising:

a slider having a slit including a slope in a second direction intersecting in the first direction;

a housing supporting the slider to slide along the first direction; and

a latch having a projection and a shaft sliding in the slit lining up in the first direction in response to the projection, the projection engaging the cage and standing out from a surface of the latch in the second direction,

wherein the housing has a pair of convexes contacting both surface in each other of area between the projection and the shaft of the latch, and

wherein the pair of convexes of the housing supports the latch to slide.

2. The optical transceiver of claim 1,

wherein the housing has a first part including one of the cage side of the pair of convexes of the housing, and a second part including the other of the pair of convexes of the housing, and

wherein the first part and the second part are fixed to each other.

3. The optical transceiver of claim 2,

wherein a third part including the slit of the slider is provided between the first part and the second part.

4. The optical transceiver of claim 2,

wherein housing has another slit including a slope in the second direction intersecting in the first direction,

wherein the latch has another shaft sliding in the another slit, the another shaft being provided between the first part and the shaft in the first direction, and

wherein the another slit is configured with engaging a concave of the first part and a concave of the second part each other.

5. The optical transceiver of claim 1,

further comprising an elasticity member biasing the slider to a second position of the slider engaging the projection of the latch and the cage from a first position of the slider releasing to engaging the projection of the latch and the cage.

6. The optical transceiver of claim 1,

wherein the latch has a concave in a surface opposite to the cage,

wherein the concave houses a convex opposite to the cage side of the pair of convexes in the latch, and

wherein the convex opposite to the cage side contacts a surface inside the concave.

7. The optical transceiver of claim 6,

further comprising a gap between the concave of the latch and the convex of the housing in the first direction, the gap determining a range sliding the latch in the first direction.

8. The optical transceiver of claim 6,

wherein an edge of the concave of the latch contacts the convex of the housing, and

wherein the latch moves with a center on the edge of the concave.

9. The optical transceiver of claim 1,

wherein the housing has another slit including a slope in the second direction intersecting in the first direction, and

wherein the latch has another shaft sliding in the another slit, the another shaft being provided between the pair of convexes and the shaft in the first direction.

10. The optical transceiver of claim 1,

wherein the slit has a portion extended in the first direction in a terminal of a slope in the first direction.

11. The optical transceiver of claim 1,

wherein the slit has a curve, a center of the curve being arranged with opposite to the cage.

12. The optical transceiver of claim 1,

wherein a width in the second direction of a portion in the latch contacting the pair of convexes of the housing, gradually increases based near the projection of the latch.

13. The optical transceiver of claim 1,

wherein a surface contacts the pair of convexes of the housing, the surface being a surface curved in inner cross-sectional along in the first direction and in the second direction.
