Abstract

FIELD: engineering elements.

SUBSTANCE: invention relates to a group of connectors for hoses and pipes. Proposed is a group of connectors including multiple connectors, wherein each connector has an outer surface for engaging with the hose, an inner through hole (13) for receiving the pipe nipple intended for connection with the hose, and a sealing tool (12) for sealing the hose with the pipe nipple. Multiple plugs (15) are provided, wherein each plug (15) has a rod part (16) inserted into the through hole (13) and an end disk part (17) for covering the end of the through hole (13) of the connector when the connector is not installed. Each two adjacent end disk parts (17) are interconnected by breakaway jumpers (20) made integral with the end disk parts (17).

EFFECT: invention simplifies work in assembling on an automatic assembly line.

Description

Prior Art

Known connectors for hoses and pipes, which are made from a number of structural parts, including sealing rings for sealing the hose and pipe. During assembly, the connector is inserted into the end of the hose, and finally the pipe is inserted into the through hole of the connector.

Disclosure of invention

The general objective of the invention is to eliminate the disadvantages inherent in prior art connectors. More specifically, the object of the invention is to provide a connector that is easier to work with during assembly and which can preferably be used in assembly on an automatic assembly line. This task is achieved by means of a connector containing an outer surface for engagement with the hose, an internal through hole for receiving a pipe nipple connected to the hose, a sealing means for sealing the connection of the hose with the pipe nipple and a plug containing a rod part made with the possibility of insertion into the specified through hole , and an end disk portion for closing the end of the through hole when the connector is in an unmounted state.

The invention is particularly suitable for connectors of the type disclosed in a co-pending international patent application under the Patent Cooperation Treaty entitled "Multi-component connector assembly", registered in the name of the same Applicant at the same time as the application, the plug in which is also designed to hold together the three components of the connector up to moment of final assembly of the connector with the hose and pipe.

The invention also relates to a group of connectors including a plurality of the above connectors, wherein each two adjacent end disk parts are connected to each other by breakable jumpers made in one piece with the end disk parts.

Brief description of the drawings

The following is a detailed description of an embodiment of the invention with reference to the drawings.

In FIG. 1 shows a connector, perspective view;

in fig. 2 is the connector shown in Fig. 1, side view;

in fig. 3 is the connector shown in Fig. 1 and 2, sectional view; and

in fig. 4 is a group of connectors including a plurality of connectors shown in FIG. 1 - 3, perspective view.

Embodiments of the invention

The connector shown in Fig. 1 - 3, designed to connect a hose (not shown) with a pipe nipple (not shown), contains a front tubular element 10, a rear tubular element 11 and an o-ring 12. The front and rear tubular elements 10, 11 have the same inner diameter and form a common a through hole 13 for receiving a pipe nipple. The outer surfaces of the front and rear tubular elements 10, 11 are made with annular protrusions for engagement with the hose. The o-ring 12 has a generally circular cross-section, and its inner and outer diameters are chosen so that it protrudes inside the through hole 13 and protrudes outward from adjacent sections of the tubular elements 10 and 11. Thus, in the assembled state of the hose with the pipe nipple, the o-ring 12 rests against the outer surface of the pipe nipple and against the inner surface of the hose.

In the state shown in the drawings, a plug 15 is placed in the through hole 13. The plug 15 includes a stem portion 16 which is generally cylindrical in shape and whose outer diameter corresponds to the diameter of the pipe nipple for which said connector is intended. When the shaft portion 16 is fully inserted, its inner end abuts against the inner flange 18, made at the rear end of the rear tubular element 11, and the disk part 17, made at the end of the plug 15, abuts against the outer flange 19 provided at the front end of the front tubular element 10 .

The plug 15 is designed to hold the three parts 10, 11 and 12 of the connector together and to seal the interior of the connector to prevent dirt from entering until the connector is finally assembled with the hose and pipe nipple. In addition, the plug facilitates crimping prior to final assembly.

In FIG. 4 shows a group of connectors in the form of a tape, containing a plurality of connectors, each of which is designed as shown in FIG. 1 - 3 connector, and connected to each other by jumpers 20, made in one piece with the disk parts 17 and each of which connects to each other a pair of adjacent plugs 15. The advantage of such a group is that it facilitates packaging and transportation, and, especially processing in the automatic assembly shop, where the connecting bridges (20) are cut.
