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. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a as shown in fig. 1 to 7 a novel waterproof termination, including casing 1, sealing insulation cream 2 and locking bolt 3, casing 1's front is provided with cavity 4, and sealing insulation cream 2 fills and is used for sealed wire joint in cavity 4.

More specifically, as shown in fig. 6, the housing 1 may also be designed as a structure with a single cavity and an internal cavity and a double cavity, the inner cavity 4 behind the locking bolt 3 is divided into a left cavity and a right cavity by a middle longitudinal step, the sealing insulating paste 2 is injected into each single cavity, and the middle step needs to be slightly higher than the sealing insulating paste 2 injected into the left cavity and the right cavity; the waterproof wiring device with the single cavity, the inner cavity and the double cavities can be used for connecting thinner wire connectors in pairs, so that the product consumption can be reduced, and the installation space can be saved.

Further, a threaded hole is formed in the top wall of the cavity 4 in a penetrating mode, the locking bolt 3 is screwed into the threaded hole formed in the top of the shell 1, and the locking bolt 3 is used for locking an insulating skin of a joint lead; meanwhile, as shown in fig. 3, a plurality of anti-slip ribs 7 are provided on the bottom wall of the cavity 4 and at a position opposite to the bottom of the locking bolt 3 to prevent the electric wire from sliding after the locking bolt 3 is locked.

The outer wall both sides of waterproof termination of this embodiment's casing 1 are fixed respectively and are provided with guide post 5 and guide way 6, and guide post 5 can be followed the casing 1 of the same kind device and openly insert in the guide way 6 of its one side with a plurality of waterproof termination of combined use to guide post 5 and guide way 6 adopt interference fit when the combined use.

More specifically, the shell 1 and the locking bolt 3 are generally formed by injection molding of engineering plastics; during assembly, a certain amount of sealing insulating paste 2 is injected into the inner cavity of the shell 1, then the locking bolt 3 is screwed in manually, and finally the locking bolt 3 is screwed in place slightly by using an electric bolt cutter.

As shown in fig. 7, a pair of novel waterproof wiring devices are combined through the guide posts 5 and the guide grooves 6, and more waterproof wiring devices with the same specification can be combined in sequence in the same way, so that the circuit arrangement can be simplified and the later maintenance can be facilitated.

This practical theory of operation:

when the device is used, firstly, the insulation skin of the wire connector part is stripped, the length is about 15-20mm, then the wire connector is twisted into a twist shape and then is folded back to be about 8-10mm, the locking bolt 3 of the waterproof wiring device is unscrewed, the folded wire connector is inserted into the bottom of the inner cavity 4 in the shell 1 (if the shell 1 is of a structure divided in a single cavity, a pair of connected wire connectors are required to be respectively inserted into the bottom of the double cavities divided in the single cavity), and finally the locking bolt 3 is screwed in to lock the insulation skin of the connector wire.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
