Description

A kind of waterproof hybrid junctioin

Technical field

The utility model is related to a kind of connector, more particularly to a kind of waterproof hybrid junctioin.

Background technology

With the continuous development of science and technology, the work and life of people be unable to do without electric power.For ease of electricity consumption, people create A variety of practical connectors, connector is a kind of connection equipment being sequentially connected with more signal wires or power cord together.

Current waterproof hybrid junctioin includes connector body, core circle, rubber ring, locking nut, and connector body is horizontal To through there is a through-hole, both ends are respectively the pulika pipe end for the steel pipe end of joint steel pipe and for connecting Plica tube, Core circle is positioned in pulika pipe end, and rubber ring is held on pulika pipe end and is sheathed on core circle, and locking nut connects for screw thread It is connected to pulika pipe end and realizes sealing to compress rubber ring.

The inner tooth thread of existing waterproof hybrid junctioin core circle is set to the inner wall of core circle, needed when installing Plica tube by The outer layer rubber of Plica tube is peelled off, then is arranged in core circle and is connected with core circle, this Connection Step is cumbersome and influences waterproof again Firmness between hybrid junctioin and Plica tube, therefore have improved space.

Utility model content

The purpose of this utility model is to provide a kind of waterproof hybrid junctioin, improves the connection of connector and Plica tube Firmness.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of waterproof hybrid junctioin, including connector body, be positioned over intrinsic core circle, be held on connector body The rubber ring of port closes connector body to compress the locking nut of rubber ring for covering, connector body include steel pipe end and Pulika pipe end, core circle boss-shaped, including first annular column and the second circular column in a ring, the mouth of the first annular column Diameter is more than the second circular column bore and its outer wall is tightly attached to pulika pipe end inner wall, the inner wall of the rubber ring and the second circular column Interval is arranged and outer wall is tightly attached to pulika pipe end inner wall.

Using the above scheme, when installation, Plica tube is arranged between rubber ring and the second circular column and uses locking screw Mother's rotation is fixed, and when locking nut rotation is fixed, rubber ring, which is inwardly constantly squeezed, makes the inner wall of rubber ring be tightly attached to Puli The outer wall of card pipe, meanwhile, the inner wall of Plica tube is tightly attached to the outer wall of the second circular column again, considerably increases the quiet of Plica tube Frictional force substantially increases firmness, and easy for installation to make Plica tube not loosen easily.

Preferably, it is provided with tapping screw thread on the second circular column periphery.

Using the above scheme, it when Plica tube is installed, by rotating and being screwed with the second circular column, further strengthens Firmness between Plica tube and connector.

Preferably, the adjacent thread spacing of tapping screw thread is 2-8mm.

Using the above scheme, by setting the spacing of tapping screw thread to 2-8mm, the firmness of Plica tube has both been ensure that Installation effectiveness is improved again.

Preferably, the rubber ring bottom end integrally extends downward into the first annular column along pulika pipe end inner wall.

Using the above scheme, rubber ring bottom end is extended into first annular column so that locking nut rotation can add when fixed The contact area of big rubber ring and Plica tube is further strengthened with increasing its stiction between Plica tube and connector Firmness.

Preferably, the first annular column is towards being connected with several on the face of second circular column for limiting The limit protrusion of rubber ring.

Using the above scheme, the setting of limit protrusion is for limiting rubber ring so that more stablizes when placing rubber ring.

Preferably, rubber ring outer wall top is provided with the first oblique surface and is arranged on locking nut inner wall top There is the second oblique surface for being matched with the first oblique surface, the rubber ring, which contacts at, to be provided with third at pulika pipe end port and tiltedly lead Face.

Using the above scheme, the setting of the first oblique surface, the second oblique surface, third oblique surface makes locking nut rotate Play the role of guiding in fixation, enables rubber ring to be easier to be squeezed in Plica tube, improve installation effectiveness.

Preferably, the junction of the first annular column and the second circular column is connected with reinforcing rib.

Using the above scheme, firmness of the setting of reinforcing rib for strengthening core circle, extends its service life.

Preferably, circumferential integrally connected restraining position ring block on the connector body inner wall.

Using the above scheme, the setting of spacing ring to stretch into because of steel pipe excessively to influence when installing steel pipe Plica tube.

In conclusion the utility model has the advantages that：

It is set as the first annular column and the second circular column of integrally connected by core circle, Plica tube is sheathed on when installation Two connecting poles, when with locking nut screwing, the outer wall of Plica tube was both mutually close to rubber ring, inner wall again with the second circular column phase Be close to, considerably increase the stiction of Plica tube, make its firmness increase and it is easy for installation.
