Description

A kind of mineral insulation heating cable connector
Technical field
The present invention relates to heating element technical field, in particular to a kind of mineral insulation heating cable connector.
Background technique
Currently, the connector of mineral insulation heating cable, there are mainly two types of connection type, one is to be welded in junction with oxygen welding Sending and receiving heated filament, is packaged in the casing of metal with high-temp glue, and metal sleeve and cable cover(ing) are made of stainless steel, generally It is only applicable to using temperature in 150 DEG C of environment below;Another is filled using magnesium oxide powder, but such connection Mode, since twisting number is more, is not fixed firmly, it is easy to fracture, the damage of connector be caused, to cable in cold and hot junction Use cause great inconvenience.
Summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of structure is simple, mineral insulation easy to use adds Electric heating cable connector.
The present invention is achieved through the following technical solutions:
A kind of mineral insulation heating cable connector, including connecting sleeve, the connecting sleeve both ends are provided with taper guarantor Pillar, setting symmetrical above and below is fluted in taper protection tube cavity, and gasket, the taper protection pipe are equipped in groove The spiro pluging hole symmetrical above and below for being provided with perforation is provided with plug screw in spiro pluging hole, and the plug screw is in contact with gasket.
Mineral insulation heating cable connector of the invention is separately installed with hair inside the left and right ends taper protection pipe Hot end and cold line end.
Mineral insulation heating cable connector of the invention, the fever end are internally provided with heating wire, the cold line end Copper core, the copper core and heating wire are internally provided in being welded to connect in connecting sleeve.
Mineral insulation heating cable connector of the invention, the copper core and heating wire outer end are provided with magnesia tube, The magnesia tube is placed in connecting sleeve.
Mineral insulation heating cable connector of the invention is welding between the connecting sleeve and taper protection pipe.
Mineral insulation heating cable connector of the invention is weldering between the cold line end and fever end and taper protection pipe It connects.
The beneficial effects of the present invention are:
Mineral insulation heating cable connector of the invention, high temperature resistant are applicable in the place for needing laser heating, expand suitable It with range, and is further fixed using the combination of taper protection pipe, gasket and plug screw and is connected between hot and cold side, connected more steady Gu whole more resistant to bending, high using safety coefficient, long service life, structure designs simple, easy for installation.
Detailed description of the invention
The present invention will be further explained below with reference to the attached drawings.
Fig. 1 is the structural diagram of the present invention.
In figure, 1 connecting sleeve;2 taper protection pipes;3 grooves;4 gaskets;5 plug screws;6 magnesia tubes;7 fever ends;8 is cold Line end;9 heating wires;10 copper cores.
Specific embodiment
The spatially relative terms such as "upper", "lower" " left side " " right side " can be used herein for ease of explanation, for saying Relationship of the elements or features relative to another elements or features shown in bright figure.It should be understood that in addition in figure Except the orientation shown, spatial terminology is intended to include the different direction of device in use or operation.For example, if in figure Device is squeezed, and is stated as being located at other elements or the element of feature "lower" will be located into other elements or feature "upper".Cause This, exemplary term "lower" may include both upper and lower orientation.
Attached drawing 1 is a kind of specific embodiment of the invention.The embodiment includes connecting sleeve 1,1 both ends of connecting sleeve It is provided with taper protection pipe 2, setting fluted 3 symmetrical above and below in 2 inner cavity of taper protection pipe is equipped with sealing in groove 3 Pad 4, the taper protection pipe 2 is symmetrical above and below to be provided with the spiro pluging hole penetrated through vertically, and plug screw 5, the spiral shell are provided in spiro pluging hole Plug 5 is connected with gasket 4, and taper protection pipe 2 protects cold line end 8 and fever end 7 and junction between the two, Can largely prevent from bending, increase service life, in addition plug screw 5 and gasket 4 to cold line end 8 and generate heat end 7 and Junction between the two is fixed and buffers, and can preferably prevent from bending, and further increases safety in utilization and uses Service life, 4 material of gasket are asbestos metal wrapping wire gasket or graphite metal wrapping wire gasket, and graphite metal spirotallic gasket uses temperature - 200-850 DEG C of degree, asbestos SW with outside ring uses -200-500 DEG C of temperature, and two kinds of gaskets are suitable for most of extremely cold very hot Environment.
Mineral insulation heating cable connector of the invention is separately installed with inside the left and right ends taper protection pipe 2 Generate heat end 7 and cold line end 8.
Mineral insulation heating cable connector of the invention, the fever end 7 are internally provided with heating wire 9, the cold line End 8 is internally provided with copper core 10, and the copper core 10 and heating wire 9 are welded to connect in connecting sleeve 1.
Mineral insulation heating cable connector of the invention, the copper core 10 and 9 outer end of heating wire are provided with magnesia Pipe 6, the magnesia tube 6 are placed in connecting sleeve 1, and magnesia tube primarily serves insulating effect, and insulating powder filling is accurate, hair Good in thermal property, sealing effect are good.
Mineral insulation heating cable connector of the invention is welding between the connecting sleeve 1 and taper protection pipe 2.
Mineral insulation heating cable connector of the invention, between the cold line end 8 and fever end 7 and taper protection pipe 2 For welding.
When installation, put on magnesia tube 6 on copper core 10 and heating wire 9, later be inserted into connecting sleeve 1 in, cold line end 8 with 7 end of end generate heat using argon arc welding welding, both ends cover upper conical protection pipe 2 later, protect later using argon arc welding welding taper Pipe 2 and connecting sleeve 1 finally screw plug screw 5 and gasket 4 are driven to move, be fixed, install to hot and cold side.
Specific implementation of the invention is described in detail above, but is intended only as an example, the present invention is not It is limited to specific implementation case described above, also within protection scope of the present invention to the equivalent modifications that carry out of the present invention.
