It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.

In the description of the present utility model, it should be noted that, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate an azimuth or a positional relationship based on that shown in the drawings, or an azimuth or a positional relationship in which the inventive product is conventionally put in use, it is merely for convenience of describing the present utility model and simplifying the description, and it is not indicated or implied that the apparatus or element referred to must have a specific azimuth, be constructed and operated in a specific azimuth, and thus should not be construed as limiting the present utility model.

As shown in fig. 1, the antistatic flame-retardant safety joint comprises a joint body 1, a front end interface 2 and a rear end interface 3 which are respectively arranged at two ends of the joint body 1, and a cable plug 4 arranged at one side of the joint body 1; the front end connector 2 and the rear end connector 3 are internally connected with a wire 6, a combination port 5 is arranged between the front end connector 2 and the rear end connector 3, a plugging channel 9 is arranged in the cable plug 4, and the bottoms of the plugging channels 9 are aligned to the combination port 5.

Compared with the prior art, in order to play a role in preventing static electricity, the cable connector is mainly coated with sealant, and the sealant plays a role in sealing on one hand and isolating static electricity of the connector on the other hand. However, the service life of the sealant is limited, and the sealant is easily affected by temperature, so that the sealant is extremely easy to fail. Moreover, the sealant is simply used, the flame retardant performance is not achieved, and the effective safety guarantee cannot be achieved when the sealant is used in a gas station. In the utility model, three-phase communication interfaces are adopted, the front end and the rear end are respectively arranged at the two ends of the connector body 1, and a common combination port 5 is arranged between the front end interface 2 and the rear end interface 3, so that different targets can be powered through one connector. One of the connectors can be closed to serve as a spare connector, and when the connector or the cable is damaged, the other connector can be started to avoid unnecessary loss caused by shutdown.

The end of the cable connector 4 is provided with a concave connector 8. A limiting ring is arranged in the plug-in port 8, and a plurality of through holes are arranged on the limiting ring. After the connection of the cable plug connector 4 is completed, the plugging position is filled with sealant through the through hole of the limiting ring, and the sealing ring is arranged at the connecting position of the plug connector, so that a complete sealing structure is formed, and a good sealing effect is achieved.

The cable plug 4 is externally wrapped with an insulating rubber sleeve 7. A flame-retardant asbestos layer is also arranged between the insulating rubber sleeve 7 and the cable plug 4.

When the connector is specifically used, the front end connector 2 and the rear end connector 3 are respectively penetrated into the lead 6, the front end connector 2 or the rear end connector 3 is fixed in the connector body 1 through screw threads, and one end of the penetrated lead 6 is connected to the position of the joint 5. It is of course also possible to use an access-only front-end interface 2 or an access-only rear-end interface 3 and to seal the other interface with an insulated threaded plug. The end of the supply cable is then inserted into the plug opening 8 and the metal plug of the supply cable is inserted into the position of the coupling opening 5. After the connection of the cable plug connector 4 is completed, the plugging position is filled with sealant through the through hole of the limiting ring, so that the fixing and sealing effects are achieved.

The above embodiments are merely for illustrating the technical solution of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
