On casing joint.Fuse is mounted in cable plug, is not needed installation in a device, is reduced the volume of equipment, when molten
When disconnected device fusing, plug top and plug lower part are separated, that is, can be taken off the fuse damaged and the fuse more renewed, fusing
Device is connect with plug top, and plug top is not charged, does not need to cut off level power supply, improves the safety of replacement fuse.
The electrode is connect with plug lower slide, and the end of electrode is provided with pier nose, is socketed with bullet on the outside of electrode
One end of spring, spring is pressed against plug lower part against the pier nose other end.On the one hand spring ensure that can between electrode and fuse
Stable connection is obtained, on the other hand the fuse of plug lower inside can be popped up when replacing fuse, not need hand
It is dynamic to take out fuse, improve the safety of replacement fuse.
Insulating layer is provided on the outside of the fuse.The insulating layer improves the insulation effect of fuse periphery.
Plug lower inside is equipped with insulation barrier, and the insulation barrier is arranged in the upside of electrode, in insulation barrier
Portion offers radial crack, and the lower end inserted into gap of fuse is contacted with electrode, the crack closure when fuse is extracted.It will
When plug top is separated with plug lower part, insulation barrier can seal electrode up for safekeeping, avoid electrode exposure in air, replacing
Electrode is electrification when fuse, and insulation barrier can be improved the security performance of plug lower part.
The plug top is elbow, and including the vertical section with the grafting of plug lower part, vertical section offers cavity, fusing
Device is mounted in cavity, the snap ring for being clamped fuse is fixed with inside vertical section, vertical section is connected with horizontal segment, described
Extinguishing arc insertion electric pole is installed, extinguishing arc insertion electric pole is fixedly connected with snap ring, and horizontal segment is offered to be inserted into extinguishing arc in horizontal segment
The coaxial conical cavity of electric pole, conical cavity and extinguishing arc insertion electric pole are used to connect the casing joint in equipment.It adopts on plug top
Cable bending is avoided straight down with the cable of elbow, the connection of plug lower part, reduces the moment of flexure that plug is subject to.Plug top
Horizontal segment and equipment casing connection, grafting is more convenient.
Compared with prior art, the present invention having the advantage that
Cable plug with self-protection function carries fuse, just not install fuse in equipment, reduce
The volume of equipment solves the problems, such as that traditional equipment inlet-outlet line can not install protection fuse.Plug top and plug lower part are
Insulation set improves the security performance of plug.Fuse in plug can be replaced, when replacing fuse fuse and insert
Head top grafting, plug top is not charged, and not needing to cut off level power supply can be replaced, and improves the peace of replacement fuse
Full performance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram with the cable plug of self-protection function.
Fig. 2 is the enlarged drawing at Fig. 1.
Fig. 3 is the explosive view with the cable plug of self-protection function.
Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that these embodiments are only used for
Illustrate the present invention rather than limit the scope of the invention, after the present invention has been read, those skilled in the art are to the present invention
The modifications of various equivalent forms fall within the application range as defined in the appended claims.
As shown in Figure 1 to Figure 3, a kind of cable plug with self-protection function, plug top 1 including insulation and absolutely
