Mill, insulating tape are wound, and program is cumbersome, inefficiency, and conducting wire and terminal gap are easy dampness oxidation, longtime running
It will lead to the even open circuit of node overheat, bury security risk.
Utility model content
The utility model is directed to above-mentioned problems of the prior art, provides a kind of moisture-proof connecting terminal of self-locking,
Solve cumbersome technique in the prior art, inefficiency, poor reliability, while for a long time by natural environment influences such as sleet, high temperature
Big problem.
The technical solution of the utility model is as follows:
The moisture-proof connecting terminal of self-locking, including connecting terminal connector, external screw thread wedge sleeve, internal screw thread wedge-lock are fixed
Pipe and moisture barrier sheath；Described connecting terminal connector one end is connected with electrical equipment interface, connecting terminal connector it is another
One end is connected with one end of external screw thread wedge sleeve, and external screw thread wedge sleeve passes through external screw thread and internal screw thread wedge lock casing phase
Even, internal screw thread wedge lock casing connection has moisture barrier sheath, and moisture barrier sheath matches with wire insulation.
One end of the connecting terminal connector is cavernous structure.
The wedge shaped shape in outer surface of the external screw thread wedge sleeve, screw thread setting is in its outer surface, external screw thread wedge shape
Inside pipe casing is reliably connected with wire metals core.
The external screw thread wedge sleeve is equipped with four gaps.
Four gap uniform intervals setting in the external screw thread wedge sleeve.
The inner surface of the external screw thread wedge sleeve is smooth isometrical tubular structure.
The internal screw thread wedge lock casing is internal screwed tubular structure, screw thread and external screw thread wedge-shaped sleeve
Screw thread on pipe matches.
The moisture barrier sheath is the tubular structure that interior diameter does not wait；Moisture barrier sheath is built-in with gasket.
One end of the moisture barrier sheath minor diameter is integrated with internal screw thread wedge lock casing connection, the moisture-proof shield
One end of set major diameter is in contact with wire insulation.
The utility model has the advantages of as follows:
(1), wedge lock structure is used for the first time, it is simpler using the moisture-proof connecting terminal connecting wire of self-locking.
(2), the moisture-proof connecting terminal of self-locking uses simple and efficient, it is only necessary to select size to strip wire insulation, insert
Enter in external screw thread wedge sleeve, then internal screw thread wedge lock casing is locked.
(3), moisture barrier sheath, it is ensured that the quality of connection of connection gap and in the future long-term running anticorrosion anti-aging energy
Power.
(4), meet node and be completely embedded reliable technical requirements, adapt to severe natural environment, higher degree avoids
The generation of the problems such as node loosening, overheat.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram under the utility model use state.
In figure, 1, connecting terminal connector, 2, external screw thread wedge sleeve, 3, internal screw thread wedge lock casing, 4, moisture-proof shield
Set.
Specific embodiment
Embodiment
As shown, the moisture-proof connecting terminal of self-locking, including connecting terminal connector 1, external screw thread wedge sleeve 2, interior spiral shell
Line wedge lock casing 3 and moisture barrier sheath 4；One end of the connecting terminal connector 1 is cavernous structure, passes through cavernous structure
It is connected with electrical equipment interface, the other end of connecting terminal connector 1 is connected with one end of external screw thread wedge sleeve 2, described
External screw thread wedge sleeve the wedge shaped shape in outer surface, screw thread setting is light inside external screw thread wedge sleeve in its outer surface
Sliding isometrical tubular structure, external screw thread wedge sleeve inside are reliably connected with wire metals core；In the external screw thread wedge sleeve
Uniform intervals are equipped with four gaps, increase elasticity, have not only been avoided that casing spalling, but also can enhance expansionary force.External screw thread wedge sleeve 2
It is connected by external screw thread with internal screw thread wedge lock casing 3, the internal screw thread wedge lock casing is internal screwed
Tubular structure, screw thread match with the screw thread in external screw thread wedge sleeve.Internal screw thread wedge lock casing 3 is connected with moisture-proof shield
Set 4, the moisture barrier sheath are the tubular structure that interior diameter does not wait, and moisture barrier sheath is built-in with gasket.The moisture barrier sheath
One end of minor diameter is integrated with internal screw thread wedge lock casing connection, and one end of the moisture barrier sheath major diameter and conducting wire are exhausted
Edge layer is in contact, and wire insulation is wrapped up inside, plays moisture-proof effect.
The connection screw thread of the internal screw thread wedge lock casing and external screw thread wedge sleeve is with standard regular screw threads.
The utility model mainly applies the principle of wedge thread rotating shrinking and moisture-proof construction protection insulated hull, and realization connects
Line terminals exempt from compression joint type connection and damp-proof protection function.In use, operating personnel has measured size, wire insulation is shelled
It removes, the metal core for stripping insulating layer is then inserted into external screw thread wedge sleeve 2, then be by the locking of internal screw thread wedge lock casing
It can.Connecting terminal head point is mainly connected with electrical equipment interface, external screw thread wedge sleeve and internal screw thread wedge lock casing
The effect for being reliably fixed conducting wire is primarily served, wire insulation set is inside played moisture-proof insulating effect by moisture barrier sheath.
