Abstract
The utility model discloses an explosion proof through wall terminal, which is an electric connector used on explosion proof equipment. A thread sleeve, an insulator and a core rod are mutually connected with each other, and each surface formed by the two components of the three is respectively provided with an unevenness groove and an unevenness platform. Mutually rotation and disassembly of each two component can not be realized in the three components, and the three components are integrated together. The structure of the utility model can meet the requirement of the explosion suppression standard, and the utility model has the advantages of simple manufacturing processes, easy use, and easy installation. The safety performance of the utility model can be enhanced.
Description
The utility model belongs to electrical connector, particularly relates to a kind of terminal through walls that is used for flame-proof electric equipment.
Each building block of existing terminal through walls is an assembly, and its manufacturing and assembly technology are all complicated, and especially for guaranteeing the flame proof standard, strict manufacturing process makes its cost higher.
The purpose of this utility model is to disclose a kind of incorporate flame proof terminal through walls, to improve the deficiency of existing terminal through walls.
The technical scheme that realizes above-mentioned purpose is:
Swivel nut (1) inwall that at one end has hexagonal flange (4) is provided with tongue and groove (6), its surface of insulator (2) that is fixed in the swivel nut matches with this tongue and groove, be provided with boss in the insulator axially extending bore, the plug (3) that is contained in this through hole that crouches has the concave surface that matches with this boss.
Insulator (2) top can be provided with boss, is connected mutually with the hexagonal flange end face of swivel nut (1);
Be shaped on annular knurl line (5) on the concave surface of cylindrical plug (3).
Further specify the technical program with drawings and Examples below:
One of accompanying drawing 1 embodiment structural profile schematic diagram.
The tongue and groove of one of accompanying drawing 2 embodiment swivel nut.
The two structural profile schematic diagrames of accompanying drawing 3 embodiment.
Embodiment as Fig. 1 is only cored structure, the terminal through walls of this form is by the working range of its physical dimension decision voltage, electric current, 1100 volts of this routine rated operational voltages, 200 amperes of rated operational currents, long 113 millimeters of copper plug (3) diameter phi 16, with the minimum creep distance of swivel nut (1) be 25 millimeters, the internal thread that the plug two ends are shaped on M10 is with fixing connected piece, swivel nut is high 31 millimeters, to guarantee its screw-in depth and to be convenient to nut (7) fastening on equipment diaphragm.
Solely the manufacturing of core wall through walls be resin with good thermal stability by die casting process, thermosetting with swivel nut and plug mutual alignment in the fixing mould promptly.The tongue and groove (6) of the swivel nut inwall that this is routine as shown in Figure 2, be two cross one another helicla flutes, annular knurl line on this groove and the plug can not rotate and dismantle swivel nut, insulator, plug three mutually, the concavo-convex combination of plug and insulator can not move up and down plug in insulator, deviate from from swivel nut when the boss of insulator upper end avoids insulator to bear axial compressive force by the hexagonal flange support.
The terminal through walls of Fig. 3 is a multicore structure, this example is 17 cores, the tongue and groove of swivel nut inwall (6) is made of two radial grooves and axial notch, the concave surface of each plug is formed by the bare wire section of electric hookup wire, each concave surface is provided with at interval, to take into account mechanical strength and dielectric strength, the making of multicore terminal through walls is identical with last example to be repeated no more.
Integrated terminal through walls of the present utility model meets the flame proof standard-required, has processing Make simply, characteristics easy to install are conducive to the flameproof electrical apparatus security performance Raising.
Claims (3)
1, flame proof terminal through walls, formed by swivel nut insulator and plug, it is characterized in that: swivel nut (1) inwall that at one end has hexagonal flange (4) is provided with tongue and groove (6), its surface of insulator (2) that is fixed in the swivel nut matches with this tongue and groove, be provided with boss in the axially extending bore of insulator, the plug (3) that is contained in this through hole that crouches has the concave surface that matches with this boss.
2, terminal through walls as claimed in claim 1 is characterized in that: insulator (2) top can be provided with boss, is connected mutually with hexagonal flange (4) end face of swivel nut (1).
3, terminal through walls as claimed in claim 1 is characterized in that: be shaped on annular knurl line (5) on the concave surface of cylindrical plug (3).
