Technology area

The utility model relates to the field of electrical engineering and is intended for the hermetic connection of two cables, which ensures the reliability of the electrical circuit.

State of the art

As a prototype to the claimed technical solution, a cable connector (US2013072050 "Electric distributor device", H01R33 / 97, 03/21/2013) is adopted, containing a union nut, a guide element, a connecting unit and a coupling nut.

In the prototype, the connecting assembly is formed by an insulation displacement connector and connecting elements, which are located in the terminal body. Insulation displacement connectors are integral with the connectors. The guide element is made in the form of a hollow cylinder and contains a part of the cable holder and a guide part. In the part of the cable holder there is a double seal for two cables. The connecting elements contain crimp clamps and are mated with cables. The guide part has paired guide elements for the conductors. When using the product to connect two cables inserted into a part of the cable holder, they are stripped to a specified length. In this case, the end areas of both cables are inserted all the way into the guide element. The corresponding crimp clamp fits into the guide part. In this case, each conductor is placed in accordance with the wiring diagram in the guide part and cut flush with a tool such as a cutter. The entire assembly is then placed in a connecting piece, preferably polarity shielded, and the tightening nut is tightened to a predetermined torque.

The technical problem to be solved is the need to use conductors of different diameters in the electrical cable connector. In addition, it is necessary to simplify the disassembly of the electrical connector to replace the wires.

The design of the prototype connector is designed for wires of a certain diameter. In addition, a complete disassembly of the cable connector is required to replace the wire.

Implementation of the technical solution

The cable electrical connector (Fig. 1) contains the first nut (1), the first and second sealing bushings (2, 3), two end parts of the body (4), the central part of the body (5), two O-rings (6), the third and the fourth sealing sleeves (7, 8), the second nut (9).

The first nut (1) contains the first sealing sleeve (2), in which the second T-shaped sealing sleeve (3) is coaxially mounted. The second nut (9) contains the third sealing sleeve (7), in which the fourth T-shaped sealing sleeve (8) is coaxially mounted.

Each end part of the body (4) contains a threaded section (10) for mating, respectively, with the first and second nuts (1, 9) and a cylindrical section with cuts (11).

Each section with cuts (11) is pressed against the sealing sleeves (2, 3, 7, 8) when the first and second nuts (1, 9) are screwed onto the end parts of the housing (4) to seal the cable.

In the central part of the housing (5) (Fig. 2) there are at least three electrical connecting elements (Fig. 3), isolated from each other by two dielectric separators (12).

Each connecting element contains a spring-loaded bracket (13) housed in a brass U-shaped element (14). Pressing elements (15) are located on the bent shelves of the bracket (13). U-shaped elements (14) contain protrusions (16) to stop the wires.

Each dielectric separator (12) (Fig. 4) contains at least three through longitudinal holes for wires (17), and latches (18) with tongues (19).

On the outer surface of the central part of the body (5), a thread is made for mating with the end parts of the body (4), a central stop shoulder (20) with flats for a key and holes for the latch tongues (21). O-rings (6) are located on both sides of the thrust collar (20).

The implementation of the proposed technical solution is not limited to the above examples.

Order of use

The ends of the cable wires stripped from the insulation are pulled through the first and second nuts (1, 9) and the end parts of the housing (4) to the longitudinal holes (17) of the dielectric separator (12) and the pressure elements (15) are bent. When bending the pressure element (15), the shelf of the bracket (13) is bent, and the wire is placed inside the connecting element, abutting against the protrusion (16) on the U-shaped element (14).

Unlike the prototype, the replaceable wire is removed by bending the pressure element (15), while there is no need to disassemble the entire device.
