Detailed Description

As shown in fig. 1-3, an aviation plug comprises a sub connector 1 and a female connector 2 which are matched with each other, wherein a convex column 3 concentric with the sub connector 1 is arranged at the lower end of the sub connector 1, a first groove 4 is formed in the convex column 3, a plurality of plug bushes 6 electrically connected with wires on the sub connector 1 are fixed in the first groove 4, a second groove 7 is formed in the upper end of the female connector 2, the convex column 3 is located in the second groove 7, a plurality of contact pins 5 electrically connected with the wires on the female connector 2 are fixed in the second groove 7, the contact pins 5 correspond to the plug bushes 6, and the contact pins 5 are inserted in the plug bushes 6.

The two sides of the outer edge of the sub-joint 1 are symmetrically provided with sliding chutes 9, the two sides of the outer edge of the female joint 2 are symmetrically fixed with fixing strips 8, the fixing strips 8 correspond to the sliding chutes 9, the fixing strips 8 are positioned in the sliding chutes 9, the fixed strip 8 is in sliding contact with the groove wall of the sliding groove 9 where the fixed strip is positioned, the upper end of the end surface of the fixed strip 8, which is back to the sub-joint 1, is provided with a vertical groove 13, the fixed strip 8 at one side of the vertical groove 13 is provided with an arc-shaped groove 14, the arc-shaped groove 14 is concentric with the sub-joint 1, the arc-shaped groove 14 is communicated with the lower end of the vertical groove 13, the vertical groove 13 and the arc-shaped groove 14 on the two fixing strips 8 are symmetrical according to the center of the axis of the sub-joint 1, the sub-joint 1 is sleeved with an upper lantern ring 11 in sliding fit with the sub-joint 1, fixing columns 12 are symmetrically fixed on two sides of the inner edge of the upper lantern ring 11, the fixing columns 12 are located in the sliding grooves 9, a lower lantern ring 10 is connected to the sub-joint 1 below the upper lantern ring 11 in a threaded mode, and the rotating direction of the lower lantern ring 10 in the rotating upward direction is the same.

When the utility model is used, the fixing strip 8 corresponds to the sliding groove 9, then the convex column 3 of the sub-joint 1 is inserted into the second groove 7 of the main joint 2, at the moment, the inserting needle 5 is inserted into the inserting sleeve 6, under the matching action of the fixing strip 8 and the sliding groove 9, the main joint 2 and the sub-joint 1 can be positioned when being inserted, further, the inserting needle 5 can be correctly inserted into the inserting sleeve 6, then, the fixing column 12 at the inner edge of the upper sleeve ring 11 corresponds to the vertical groove 13 on the fixing strip 8, the upper sleeve ring 11 descends, the fixing column 12 enters the bottom of the vertical groove 13 and then rotates the upper sleeve ring 10, the fixing column 12 is positioned in the arc-shaped groove 14, the lower sleeve ring 10 is screwed to spirally ascend, when the lower sleeve ring 10 tightly abuts against the upper sleeve ring 11, the fixing strip 8 on the main joint 2 is stabilized in the sliding groove 9 of the sub-joint 1, further, the main joint 2 and the sub-joint 1 are stabilized, because the rotating direction of the lower sleeve ring 10 is the same as the extending direction of, therefore, when the lower sleeve ring 10 is screwed up and tightly pressed against the upper sleeve ring 11, the fixing posts 12 on the inner edge of the upper sleeve ring 11 are not withdrawn from the arc-shaped grooves 14.
