Description
Technical field
The utility model relates to heating element, particularly relates to the syndeton of a kind of heating wire and binding post and has its quartz electrothermal tube.
Background technology
Quartz electrothermal tube is widely used as infrared radiation electric heater, in pharmacy, and plastics, packing, is used in the industries such as household electrical appliances in a large number, is main dissipative cell in equipment.The main quartz ampoule of existing quartz electrothermal tube, insulating base, heating wire and binding post form, the two ends of described quartz ampoule are provided with described insulating base, described heating wire is contained in described quartz ampoule, and described heating wire two ends adopt crimping to realize with described binding post and are electrically connected to.As shown in Figure 1, the pressure contact portion 12 of existing heating wire 10 is hook-shaped, and heating wire 10 is little with binding post 20 contacts area, and crimping is unreliable, very easily occurs the phenomenon that gets loose, and causes after sale and the athermic phenomenon of quartz electrothermal tube often appears in production line.
Summary of the invention
For above-mentioned prior art present situation, technical problem to be solved in the utility model is, the syndeton of a kind of heating wire and binding post is provided, the contact area of its heating wire and binding post is large, to improve the firm reliability of heating wire and binding post, reduce quartz electrothermal tube failure rate after sale.Another technical problem to be solved in the utility model is, a kind of quartz electrothermal tube with this syndeton is provided.
In order to solve the problems of the technologies described above, the syndeton of a kind of heating wire provided by the utility model and binding post, the end of described heating wire is provided with pressure contact portion, the terminals of described binding post are provided with crimping piece, described crimping piece is realized and being electrically connected to described pressure contact portion crimping, and described pressure contact portion is roundabout bending.
In an embodiment, described pressure contact portion is " N " shape therein.
In an embodiment, described pressure contact portion is " M " shape therein.
In an embodiment, described crimping piece is curl shape therein.
In an embodiment, described crimping piece is two therein, and two described crimping pieces are curled into the inside by two opposite side of the terminals of described binding post.
A kind of quartz electrothermal tube provided by the utility model, comprise quartz ampoule, insulating base, heating wire and binding post, the two ends of described quartz ampoule are provided with described insulating base, described heating wire is contained in described quartz ampoule, it is characterized in that, described heating wire two ends adopt above-mentioned syndeton realization to be connected with described binding post.
Compared with prior art, the syndeton of heating wire of the present utility model and binding post and there is its quartz electrothermal tube, because the pressure contact portion of heating wire is roundabout bending, increased the contact area of heating wire and binding post, not only increased the firm reliability between crimping piece and described pressure contact portion, improved the mechanical strength of crimping place, the terminal rate that gets loose declines, and this syndeton can also reduce binding post temperature rise, improve heating wire useful life.
The beneficial effect that the utility model additional technical feature has will partly describe in this specification embodiment.

Embodiment
Below with reference to accompanying drawing, also the utility model is elaborated in conjunction with the embodiments.It should be noted that, in the situation that not conflicting, the feature in following embodiment and embodiment can combine mutually.
Figure 2 shows that the schematic diagram of heating wire in the present embodiment one 10 and the syndeton of binding post 20, Figure 3 shows that the enlarged diagram of the pressure contact portion 12 of the heating wire 10 in Fig. 2.As shown in the figure, the end of described heating wire 10 is provided with pressure contact portion 12, and described pressure contact portion 12 is " N " shape, and the terminals of described binding post 20 are provided with crimping piece 22, and described crimping piece 22 is realized and being electrically connected to described pressure contact portion 12 crimping.
Heating wire 10 in the present embodiment and the syndeton of binding post 20, because the pressure contact portion 12 of heating wire 10 is roundabout bending, increased the contact area of heating wire 10 with binding post 20, not only increased the firm reliability between crimping piece 22 and described pressure contact portion 12, improve the mechanical strength of crimping place, the terminal rate that gets loose declines, and this syndeton can also reduce binding post 20 temperature rises, improves 10 useful lifes of heating wire.
Preferably, described crimping piece 22 is curl shape.Further, described crimping piece 22 is two, and two described crimping pieces 22 are curled into the inside by two opposite side of the terminals of described binding post 20.
