Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

As shown in fig. 1-2, the utility model provides a dual power change-over switch wiring dropout prevention means, can insert with wiring plug 2 and jack 3 of being connected of seting up on switch main part 1 and wiring plug 2 and the switch main part 1, the detachable rubber sleeve circle 4 that has cup jointed of bottom surface of wiring plug 2, a mounting groove 6 has all been seted up to the surface of switch main part 1 and the left and right sides that is located jack 3, the inside of every mounting groove 6 all rotates through pivot 7 and is connected with a spacing arm 5, the top of two spacing arms 5 all an organic whole has linked firmly a wedge dop 10 that can the butt at rubber sleeve circle 4 upper surface.

In an alternative embodiment, the bottom ends of the two limiting arms 5 are integrally and fixedly connected with a pressing rod 11, and the tail ends of the two pressing rods 11 are inclined upwards.

In an alternative embodiment, a leaf spring 8 is fixedly connected to the inside of each mounting groove 6 and located at the lower side of the pressing rod 11, and the upper surface of the leaf spring 8 is movably attached to the lower surface of the pressing rod 11.

In an alternative embodiment, the outer surface of the switch body 1 between the mounting groove 6 and the jack 3 is provided with a caulking groove 9 matched with the rubber ferrule 4.

In an alternative embodiment, the top end of the connection plug 2 is electrically connected to one end of the data connection.

The working principle is as follows: in the embodiment, the device can limit the wiring plug 2, so that the wiring plug 2 is prevented from falling off from the jack 3; the rubber ferrule 4 in the scheme can be freely disassembled from the end part of the wiring plug 2, so that the use flexibility is increased; in the scheme, the wedge-shaped chucks 10 at the top ends of the two limiting arms 5 can automatically abut against the two sides of the upper surface of the rubber ferrule 4 under the elastic action of the leaf spring 8, so that the rubber ferrule 4 is limited downwards, and the inserting core at the bottom end of the wiring plug 2 is always positioned in the inserting hole 3; through the design of the caulking groove 9, the disassembled 4 can be conveniently accommodated in the caulking groove 9 to prevent loss; specifically, when the wiring plug 2 is inserted, the wiring plug 2 is directly inserted into the jack 3 from top to bottom, and since the upper surface of the wedge-shaped chuck 10 is of a curved surface structure, downward movement of the wiring plug 2 and the rubber ferrule 4 is not affected, and after the rubber ferrule 4 moves to a position below the wedge-shaped chuck 10, the leaf spring 8 pushes the pressing rod 11 to rotate upwards by taking the rotating shaft 7 as an axis through elastic force, so that the wedge-shaped chuck 10 is driven to rotate to a position above the rubber ferrule 4 through the limiting arm 5, a downward limiting effect is further achieved on the rubber ferrule 4, and a plug core at the bottom end of the wiring plug 2 is prevented from being separated from the jack 3; when the wiring plug 2 is drawn out, the two fingers simultaneously press the two pressure rods 11 downwards, the wedge-shaped clamping head 10 is driven by the limiting arm 5 to rotate towards the other side so as to be screwed off from the upper surface of the rubber ferrule 4, and then the wiring plug 2 is drawn out upwards.
