Abstract
A retention assembly for positioning a mounting component slidably arranged on a frame, the retention assembly includes a detent cylinder defining a receiving hole therethrough, a cap covering the receiving hole, and a retention ball and an elastic member located in the receiving hole, the elastic member is arranged between the retention ball and the cap for pressing the retention ball to protrude from the receiving hole and insert into a positioning hole of the mounting component when the positioning hole is aligned with the retention ball. The retention assembly improves convenience of positioning the mounting component relative to the frame and the convenience of maintenance on the electronic components mounted on the mounting component. A chassis including the retention assembly is also provided.
Claims11
A retention assembly for positioning a mounting component slidably arranged on a frame, comprising:
- a detent cylinder comprising a first end and a second end opposite to the first end, wherein the first end defines a first opening, the second end defines a second opening, the detent cylinder defines a receiving hole communicates with the first opening and the second opening, and a diameter of the receiving hole gradually decreases towards the first opening, the detent cylinder is provided with a protrusion surrounding the first opening at the first end, the protrusion is configured for inserting into a mounting hole of the frame for connecting the detent cylinder to the frame;
- a cap connected to the second end of the detent cylinder for covering the second opening and enclosing the receiving hole;
- a retention ball located in the receiving hole, a diameter of the retention ball is larger than a diameter of the first opening, and
- an elastic member located in the receiving hole, the elastic member is arranged between the retention ball and the cap for pressing the retention ball towards the first opening, the elastic member is configured for pressing the retention ball to protrude from the receiving hole and insert into a positioning hole of the mounting component when the positioning hole is aligned with the retention ball.
A retention assembly for positioning a mounting component slidably arranged on a frame, comprising:
- a main body defining a receiving cavity, wherein the receiving cavity defines a first opening at a first end of the main body, the main body is provided with a protrusion surrounding the first opening at the first end, the protrusion is configured for inserting into a mounting hole of the frame for connecting the main body to the frame;
- a retention ball received in the receiving cavity, wherein a diameter of the retention ball is larger than a diameter of the first opening;
- and
- an elastic member located in the receiving cavity, wherein the elastic member is arranged between the retention ball and a bottom of the receiving cavity for pressing the retention ball towards the first opening, the elastic member is configured for pressing the retention ball to protrude from the receiving cavity and insert into a positioning hole of the mounting component when the positioning hole is aligned with the retention ball.
