Description

Integrated heater convenient to assemble

Technical Field

The utility model relates to a heater, concretely relates to integrated heater of convenient assembly.

Background

The traditional integrated heater structurally usually uses a plurality of wires to connect a heating working part and a power supply, but the wire connecting structure has many problems in actual assembly, firstly, the assembly is difficult due to the narrow space of a shell, secondly, the corresponding welding point of each wire is fixed during welding, and even if the wires have line colors, the condition of wrong welding positions can be caused due to the fact that the wires do not have guidance.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing an integrated heater of convenient assembly, it is inconvenient that the wire is connected the assembly in solving the heater, does not have the guidance quality, appears the position mistake easily and leaks.

The technical scheme is as follows: make things convenient for integrated heater of assembly, which comprises a housin, inside circuit board and the lower circuit board of being provided with of casing, go up the circuit board and switch on through connecting the guide pillar between the circuit board down, the casing upper end is provided with the protection pipe, be provided with the heating plate in the protection pipe, the heating plate switches on with last circuit board through electrically conductive heat conduction polar plate.

In order to prevent the interference generated during the assembly of the integrated piece and reduce the difficulty in opening the plastic piece mold, the shell comprises an upper shell, a main shell and a lower shell, and the three shells are detachably mounted together.

The electric and heat conducting polar plates comprise two, and the heating plates are fixed between the two electric and heat conducting substrates through screws.

The heating plate is a PTC heating plate.

The circuit board is a PCB board.

The connecting guide posts are arranged in the through holes corresponding to the upper circuit board and the lower circuit board.

Has the advantages that: the utility model discloses a connection structure of connecting the guide pillar can simplify the assembly, and the guide connection that corresponds does not have the phenomenon that the wrong welding leaks to weld, solves product assembly and wrong welding problem.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-6, the integrated heater convenient for assembly comprises a shell, the shell comprises an upper shell 11, a main shell 1 and a lower shell 12, an upper circuit board 2 and a lower circuit board 3 are arranged inside the shell, through holes are formed in corresponding positions of the upper circuit board 2 and the lower circuit board 3, a connecting guide pillar 4 is installed in the through holes of the two circuit boards to realize electric conduction, a protection circular tube 5 is arranged at the upper end of the shell, a heating plate 6 is arranged in the protection circular tube 5, the heating plate 6 is conducted with the upper circuit board 2 through an electric conduction and heat conduction polar plate 8, the electric conduction and heat conduction polar plate 8 comprises two heating plates 6, the heating plate 6 is fixed between the electric conduction and heat conduction polar plates 8 through a screw nut. Wherein, the connecting guide post includes two kinds of connecting guide post structures, the lower extreme of first connecting guide post has a protrusion, can block and be unlikely to drop in the aperture of printing board, and the second connecting guide post does not have the protrusion, so the second connecting guide post welds in advance on the PCB board and need not have the protrusion, so the two also differs in width size because PCB board circuit design, can be thicker a little through the great first connecting guide post of electric current, and the guide post is relatively thin a bit to the less second connecting guide post of electric current, so be equivalent to saved material cost.

When using the utility model discloses the time, its inside connection structure who constitutes through last circuit board, connection guide pillar, lower circuit board carries out inside circuit connection, and the heating plate is installed between two conductive polar plates, through foretell circuit board connection structure switch-on circuit work, and the protection pipe at top protects heating element part not to receive the damage.
