Technical Field

[0001] The utility model relates to the technical field of aviation plugs, in particular to an aviation plug with a waterproof wiring harness. Background Art

[0002] Aviation plugs, also known as aviation jacks, are electromechanical components that connect electrical circuits and are widely used in aerospace, defense, electronic communications, industrial machinery, medical equipment, new energy and other fields. It is a very important component of avionics equipment and is used to connect electrical and electronic systems. Aviation plugs play a role in connecting or disconnecting circuits in aircraft, ships, vehicles and other transportation vehicles.

[0003] At present, most of the wires used in aviation plugs are waterproofed by the protective layer covering the outside. However, when connected to the aviation plug, the external protective layer cannot be deeply embedded with the aviation plug. The simple plug-in fit is prone to water seepage during later use, which poses certain safety hazards. In view of this, we propose an aviation plug with a waterproof wiring harness. Utility Model Content

[0007] The conductor includes a wire core and a protective layer arranged on the wire core, the protective layer is arranged between the external threaded tube and the sleeve, and the protective layer is pushed by the annular inner convex key and the annular outer convex key to form an S-shaped waterproof fold edge for improving the waterproof effect.

[0008] Preferably, an annular sleeve slope for facilitating the sleeve installation of a protective layer is provided on a side of the outer edge surface of the externally threaded tube away from the plug body, and the wire core is arranged in the externally threaded tube.

[0009] Preferably, an internal thread ring is configured on a side of the inner edge surface of the sleeve away from the annular inner convex key, and the internal thread ring is threadedly mounted on the outer edge surface of the external threaded pipe.

[0010] Preferably, the annular outer convex key and the annular inner convex key are both circular rings with semicircular protrusions, and the two semicircular protrusions mutually squeeze the protective layer from the inner side and the outer side of the protective layer.

[0011] Preferably, the protective layer forms a waterproof cavity by extruding the annular outer convex key and the annular inner convex key in opposite directions to cooperate with the external threaded tube, and the wire core is arranged in the waterproof cavity.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1 The utility model rotates the sleeve to push the protective layer from both inside and outside through the annular inner convex key on the sleeve and the annular outer convex key on the external threaded pipe, forming an S-shaped waterproof fold edge on the protective layer, thereby improving the waterproof effect after the protective layer is connected to the external threaded pipe. Through the deep embedding method, the problem of water seepage in the later use process is avoided, eliminating safety hazards.

[0014] 2. The utility model facilitates the wire core to be separated from the protective layer after being inserted into the external threaded pipe through the annular sleeve bevel arranged on the external threaded pipe, and facilitates the protective layer to slide between the annular outer convex key and the annular inner convex key, thereby facilitating the subsequent waterproof operation of the connection, saving time and effort during installation, and having strong practicality.

[0022] Further, to avoid water seepage during later use, see Figure 1 , Figure 2 , Figure 3 , Figure 4 The waterproof sleeve 3 includes an externally threaded tube 301 fixedly arranged at one end of the plug body 1 and a sleeve 302 threadedly mounted on the externally threaded tube 301. An annular external convex key 303 is configured on one side of the outer edge surface of the externally threaded tube 301, and an annular internal convex key 304 matching the annular external convex key 303 is configured on one side of the inner edge surface of the sleeve 302. The wire 2 includes a wire core 201 and a protective layer 202 arranged on the wire core 201. The protective layer 202 is arranged between the externally threaded tube 301 and the sleeve 302, and the protective layer 202 is supported by the annular internal convex key 304. The mutual pushing of the convex key 304 and the annular external convex key 303 forms an S-shaped waterproof fold edge 203 for improving the waterproof effect. The sleeve 302 is rotated to complete the pushing of the protective layer 202 from both inside and outside through the annular internal convex key 304 on the sleeve 302 and the annular external convex key 303 on the external threaded tube 301, so as to form an S-shaped waterproof fold edge 203 on the protective layer 202, thereby improving the waterproof effect after the protective layer 202 is connected to the external threaded tube 301. By deep embedding, the problem of water seepage in the later use process is avoided, thereby eliminating safety hazards.

[0023] Furthermore, to facilitate waterproofing of the joints, see Figure 2 , Figure 3 , Figure 4The outer edge of the external threaded tube 301 is provided with an annular sleeve bevel 305 on the side away from the plug body 1 for facilitating the sleeve of the protective layer 202, and the wire core 201 is arranged in the external threaded tube 301, and the inner edge of the sleeve 302 is provided with an inner thread ring 306 on the side away from the annular inner convex key 304, and the inner thread ring 306 is threadedly mounted on the outer edge of the external threaded tube 301, the annular outer convex key 303 and the annular inner convex key 304 are both rings with semicircular protrusions, and the two semicircular protrusions are formed by the protective layer 202. The inner and outer sides of the protective layer 202 are squeezed against each other, and the protective layer 202 is squeezed in opposite directions by the annular outer convex key 303 and the annular inner convex key 304 to cooperate with the external threaded tube 301 to form a waterproof cavity, and the wire core 201 is arranged in the waterproof cavity. The annular sleeve bevel 305 arranged on the external threaded tube 301 facilitates the wire core 201 to be inserted into the external threaded tube 301, and then separated from the protective layer 202, so that the protective layer 202 slides between the annular outer convex key 303 and the annular inner convex key 304, thereby facilitating the subsequent waterproof operation of the connection, saving time and effort during installation, and having strong practicality.
