The utility model discloses a realize through following technical scheme: a self-locking cable connector for a railway turnout snow melting heating element comprises a plug and a socket, wherein a plurality of first limiting blocks are arranged on the outer surface of one end of the plug, a plurality of second limiting blocks are arranged on the inner surface of one end of the socket in a matched mode, and springs are arranged on one sides of the second limiting blocks.

Preferably, the plug and the socket are provided with opposite transverse arrows, and the socket is also provided with a longitudinal arrow.

Preferably, the first limiting block is hook-shaped, and the second limiting block is matched with the triangle.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a combined action of a plurality of stoppers that are equipped with on the surface of plug one end one, a plurality of stoppers that match and be equipped with two and the spring on the socket one end internal surface realizes connecting from locking-type of plug and socket, convenient and fast, and the leakproofness is good.

Drawings

Fig. 1 is a front view of a plug and socket of the present invention;

fig. 2 is a cross-sectional view of the socket of the present invention.

In the drawings: 1. a plug; 2. a first limiting block; 3. a socket; 4. a second limiting block; 5. a spring.

Detailed Description

As shown in fig. 1 to 2 in the attached drawings of the specification, the self-locking cable connector for the railway turnout snow melting heating element comprises a plug 1 and a socket 3, wherein a plurality of limiting blocks I2 are arranged on the outer surface of one end of the plug 1, a plurality of limiting blocks II 4 are arranged on the inner surface of one end of the socket in a matching manner, and a spring 5 is arranged on one side of each limiting block II 4.

The plug 1 and the socket 3 are provided with opposite transverse arrows, and the socket 3 is also provided with a longitudinal arrow.

The first limiting block 2 is hook-shaped, and the second limiting block 4 is triangular and matched with the first limiting block.

Adopt plug 1 and socket 3 to connect from locking-type, when plug 1 inserts socket 3, 1 male one end of plug extrudees spring 5 simultaneously, plug 1 can get into in socket 3 completely, the rotatory socket 3 of the direction of the vertical arrow point that is equipped with simultaneously on socket 3 makes stopper two 4 slide into the inslot between two stopper one 2, loosen socket 3 this moment, a plurality of stopper two 4 that match on the 3 internal surface of socket are equipped with firmly under the horizontal and fore-and-aft effect of spring 5 elasticity tightly hook the side of stopper one 2, and is quick and fastening, connection fastening and leakproofness between two sections cables are good.

In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
