Description

Switch cabinet bus connector

Technical Field

The utility model relates to the technical field of bus connectors, in particular to a switch cabinet bus connector.

Background

In medium-high voltage switchgear, bus bar expansion is typically achieved using bus bar connectors. The bus connector not only ensures reliable electric connection of buses, but also ensures external insulation, and the performance of the bus connector directly influences the safety and reliability of a power transmission and distribution system.

In the process of using the bus connector, not only the smooth connection of the bus is ensured, but also the stability of bus connection is required, but in the connection process of the existing bus connector and the bus, the connection stability is poor, and further the bus is loosened, so that reliable electric connection cannot be realized.

Disclosure of Invention

The utility model aims to provide a bus connector of a switch cabinet, so as to solve the problem of poor connection stability of the bus connector in the background art.

In order to solve the technical problems, the utility model provides the following technical scheme:

the utility model provides a cubical switchboard busbar connector, includes the connector body, evenly arranged has four elasticity fastening piece on the port a week at both ends about the connector body, be equipped with the inclined plane on the elasticity fastening piece outer end, and be equipped with the screw thread on the inclined plane, elasticity fastening piece threaded connection has the adapter sleeve, be equipped with the thread groove of round platform shape structure in the adapter sleeve, the thread groove with screw thread on the elasticity fastening piece inclined plane is connected.

Further, the connector body is sleeved with an insulating sleeve.

Further, the distance from the inner end of the thread groove to the elastic fastening piece is equal to the distance from the inner end surface of the fastening sleeve to the insulating sleeve.

Further, the inner side outer end of the elastic fastening piece is provided with a pressing head.

Compared with the prior art, the utility model has the following beneficial effects:

according to the bus connector, the elastic fastening piece is pressed downwards through screwing the fastening sleeve and then through the round table-shaped thread groove in the fastening sleeve, so that the bus is tightly pressed, the connection between the bus and the bus connector is more tight, and the connection stability of the bus connector is improved.

Drawings

The accompanying drawings are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate the utility model and together with the embodiments of the utility model, serve to explain the utility model. In the drawings:

FIG. 1 is a cross-sectional view of the structure of the present utility model;

fig. 2 is an enlarged schematic view of a in fig. 1.

In the figure: 1. a connector body; 2. an elastic fastening tab; 3. a fastening sleeve; 4. a thread groove; 5. an insulating sleeve; 6. pressing the head.

Detailed Description

For the purpose of further illustrating the various embodiments, the present utility model provides the accompanying drawings, which are a part of the disclosure of the present utility model, and which are mainly used to illustrate the embodiments and, together with the description, serve to explain the principles of the embodiments, and with reference to these descriptions, one skilled in the art will recognize other possible implementations and advantages of the present utility model, wherein elements are not drawn to scale, and like reference numerals are generally used to designate like elements.

According to an embodiment of the utility model, a switchgear busbar connector is provided.

Embodiment one:

as shown in fig. 1-2, the bus connector of the switch cabinet comprises a connector body 1, four elastic fastening pieces 2 are uniformly arranged on the periphery of ports at the left end and the right end of the connector body 1, inclined surfaces are arranged at the outer ends of the elastic fastening pieces 2, threads are arranged on the inclined surfaces, the elastic fastening pieces 2 are in threaded connection with a fastening sleeve 3, a thread groove 4 with a truncated cone-shaped structure is arranged in the fastening sleeve 3, and the thread groove 4 is connected with the threads on the inclined surfaces of the elastic fastening pieces 2;

embodiment two:

the connector body 1 is sleeved with an insulating sleeve 5, and two ends of the insulating sleeve 5 are of a conical structure;

the distance from the inner end of the thread groove 4 to the elastic fastening piece 2 is equal to the distance from the inner end face of the fastening sleeve 3 to the insulating sleeve 5, as shown by b=c in fig. 1, so that after the fastening sleeve 3 is completely screwed, the inner end face of the fastening sleeve 3 is just stuck to the end face of the insulating sleeve 5;

the outer end of the inner side of the elastic fastening piece 2 is provided with a pressing head 6, and the pressing head 6 can sink into the leather sheath of the bus, so that the elastic fastening piece 2 is pressed more tightly and the connection is more tightly;

the working principle of the utility model is as follows:

when the bus is installed, the bus is inserted into the connector body 1, then the tightening sleeve 3 is screwed, and the elastic tightening piece 2 is gradually pressed downwards in the process of screwing the tightening sleeve 3, so that the pressing head 6 can sink into the leather sleeve of the bus, and the bus is pressed;

therefore, the elastic fastening piece 2 is pressed downwards through screwing the fastening sleeve 3 and then through the round table-shaped thread groove 4 in the fastening sleeve 3, so that the bus is tightly pressed, the connection between the bus and the bus connector is more fastened, and the connection stability of the bus connector is improved.
