Abstract

The invention provides a bus duct socket. The bus duct socket comprises a socket base and a socket assembly arranged on the socket base, wherein the socket assembly comprises socket substrates, limit strengthening ribs, and copper bars, the socket base bodies are arranged at two ends of the socket assembly, the limit strengthening ribs and the copper bars are arranged on the two socket substrates, and the cross section of the limit strengthening rib is in a trapezoidal structure with a big upper end and a small lower end. When the socket assembly is plugged into plugging feet, the plugging feet are arranged between the two socket substrates, the trapezoidal structures of the limit strengthening ribs cooperates with the inner side of the plugging feet to conduct limit, and the end parts of the plugging feet are closely fitted together. The bus duct socket has the advantages that: small scale deviations caused in installation and transportation process can be ignored, the problems that bias plugging and empty plug of the plugging feet when the plugging feet is plugged into the socket due to great phase allowance are eliminated, and product accuracy is improved, and no form adjustment is needed after assembly of the bus duct, the needs of flow line production is met, and working efficiency is improved.

Description

The bus duct socket

Technical field

This utility model relates to a kind of parts of low voltage bus bar groove, particularly a kind of bus duct socket.

Background technology

Low voltage bus bar groove is the staple product that electric power transfer is responsible in low pressure power transmission and distribution fields, in large electric current and industrial and mineral, factories and miness place, have cable incomparable a bit.Wherein most important is also that the weakest link is " plug-in units ", and the key of plug-in units is the plug receptacle between jack box and bus duct body.Loose contact due to departing from of plug receptacle, is caused in a lot of places, causes whole piece bus duct scaling loss, and even a large amount of power consumption equipment scaling loss cause serious economic loss, and potential safety hazard.

During installation, the phase place of the socket copper bar of low voltage bus bar groove is generally 16mm or 19mm, due to after the factors such as collision deformation in metal hardness characteristic, press-bending accurate to dimension and the transportation of copper bar self impacts causes the bus duct overall package good, it is very accurate that the phase place of socket copper bar is difficult to guarantee, easily insert partially when pin inserts the socket copper bar, cause pin truly not insert copper bar and produce virtual connection.

Will rebuild one by one each socket when bus duct assembling is produced, and in plant produced due to the socket position uncertainty at bus duct, be unfavorable for the mold batch machining, affect production work efficient, be difficult to guarantee product quality.

Summary of the invention

Goal of the invention: be to provide a kind of not high and can guarantee to draw the bus duct socket of grafting quality to copper bar self hardness and press-bending requirement on machining accuracy for above problem the purpose of this utility model.

Technical scheme: a kind of bus duct socket comprises socket pedestal and the socket assembly that is arranged on the socket pedestal; Described socket assembly comprise two ends the socket matrix, be arranged on spacing reinforcement and copper bar on two socket matrixes; The cross section of described spacing reinforcement is small top and big bottom trapezium structure; When the socket assembly inserted pin, described pin was between two socket matrixes, and the trapezium structure of spacing reinforcement coordinates spacing with the pin inboard, and described pin end and copper bar closely cooperate.The socket pedestal is monolithic construction, and the socket pedestal guarantees position and the overall dimension in the hole of mounting socket assembly by the dimensional tolerance of press mould, thereby has guaranteed the global tolerance of whole socket.When pin inserts socket, play the guide effect of pin when inserting socket by spacing reinforcement.

Beneficial effect: 1, the utility model can be ignored the deviation among a small circle that causes in installation, transportation, has eliminated socket phase place tolerance large, thereby inserts inclined to one side, plug hole problem when causing pin to insert socket, has improved Product Precision; 2, realized that the rear socket of bus duct assembling need not shaping, satisfied streamline production, improved operating efficiency.

Fig. 2 is the structural representation of the utility model socket assembly.

Fig. 3 is the structural representation that the utility model pin does not insert the socket assembly.

Fig. 4 is the structural representation that the utility model pin inserts the socket assembly.

Embodiment

The invention will be further described below in conjunction with accompanying drawing.

As shown in the figure, a kind of bus duct socket comprises socket pedestal 1 and the socket assembly 2 that is arranged on socket pedestal 1; Described socket assembly 2 comprise two ends socket matrix 3, be arranged on spacing reinforcement 4 and copper bar 5 on two socket matrixes 3; Described socket matrix 3 is insulating material; The cross section of described spacing reinforcement 4 is small top and big bottom trapezium structure; When socket assembly 2 inserted pin 6, described pin 6 was between two socket matrixes 3, and the trapezium structure of spacing reinforcement 4 coordinates spacing with pin 6 inboards, and described pin 6 ends and copper bar 5 closely cooperate.Socket pedestal 1 is monolithic construction, and socket pedestal 1 guarantees position and the overall dimension in the hole of mounting socket assembly 2 by the dimensional tolerance of press mould, thereby has guaranteed the global tolerance of whole socket.When pin 6 inserts socket, play the guide effect of pin 6 when inserting socket by spacing reinforcement 4.
