Abstract
The utility model discloses a bracket used for a PTC thermal sensitive ceramic electric heater, comprising a mounting surface and a supporting surface, wherein the supporting surface is provided with an inner concave cavity for mounting and fixing a heating element; the bottom of the inner concave cavity is also provided with an inward extended cavity body which is used for placing a connecting lead wire on the power supply leading-out end of the heating element; and the supporting surface on the bottom of the cavity body is provided with a lead wire leading-out port. The utility model also discloses the PTC electric heater using the bracket, and has the advantages: 1. all leading-out live parts and leading-out lead wires of a power supply electrode are in a closed state to prevent the influence of external dirty air and the impact of external force, so the PTC electric heater completely accords with higher safety requirements. 2. a temperature fuse protector with a circular tubular structure is adopted, which can bear current impact of a heater with higher power, so the PTC electric heater has a wider application range; 3. the fuse protector passes through a through hole of the bracket, so that not only the fuse protector can accurately sense the change of temperature of the heater, but also the whole structure of the electric heater is simplified; and 4. the manufacturing cost for the heater is reduced.
Description
Technical field
The utility model relates to a kind of PTC thermal sensitive ceramics electric heater support, and the PTC electric heater.
Background technology
The use of PTC electric heater very extensively, especially the use in air conditioner is very extensive.Because ptc heater is installed in the air conditioner by support, so having relatively high expectations to support.Except insulating requirements, also to satisfy requirement safe, simple in structure, easy for installation.Yet existing heater, the power supply lead wire of its heater is connected by metal insert that is attached at PTC heater exit and the slotting spring of metal that is crimped on the conduction wire harness.For the PTC heater of many groups parallel connection, the on line between contact place and the electric power polarity also is to be interlinked by inserted sheet and slotting spring.Live parts such as these bindings slotting spring, sheath and inserted sheet all expose the outside at support, are exposed in the air, and not only complex structure causes cost higher.Simultaneously, long-term use meeting oxidation reduces bond strength, has the hidden danger that comes off through external force vibrations, shake, and is extremely dangerous.In addition, prior art is taked lead type rectangle temperature fuse and is installed in the inner chamber of support, and the temperature-sensitive reaction time is slow, mounting process complexity, cost are also higher, owing to be subjected to the restriction of specification and structure, can't bear the above impulse current of power 800W, the scope of application is restricted.
Summary of the invention
Goal of the invention: the purpose of this utility model provides a kind of PTC thermal sensitive ceramics electric heater support safer, simple in structure.
Another purpose of the present utility model provides a kind of above-mentioned support that has, and can reduce cost, install PTC electric heater more simply and easily.
Technical scheme: PTC thermal sensitive ceramics electric heater support described in the utility model, comprise installed surface and supporting surface, on supporting surface, be provided with the indent die cavity that installs and fixes heater, it is characterized in that: also be provided with the cavity that is used to place heating unit power exit connection lead that extends internally in the bottom of indent die cavity, on the supporting surface of this cavity bottom, be provided with the lead fairlead.
In order to make fuse can reach result of use accurately, simultaneously, guarantee that fuse has a rational installing space in limited space, the utility model is provided with the through hole that is used to place fuse on supporting surface one sidewall of support.
PTC electric heater described in the utility model, comprise heater and the support that is fixed on the heater two ends, support comprises installed surface and supporting surface, on supporting surface, be provided with the indent die cavity that installs and fixes heater, it is characterized in that: the support that is positioned at the heating unit power exit also is provided with the cavity that is used to place heating unit power exit connection lead that extends internally in the bottom of indent die cavity, be provided with the lead fairlead on the supporting surface of this cavity bottom.
By the same token, electric heater described in the utility model is provided with the through hole that is used to place fuse on a sidewall that is positioned at heating unit power exit support.
Beneficial effect: the utility model compared with prior art, its advantage is: 1, as safe as a house.Owing in an end support of the power outlet of electric heater, be provided with the cavity that is used to place with the enclosed-electrode lead-in wire, make all power electrode leads component and lead be in closed state, only needing two leads to draw from the fairlead of support gets final product, be not subjected to the influence of outside foul atmosphere and the impact of external force, meet higher safe requirement fully.2, adopted the cylindrical temperature fuse that can bear the greater impact electric current, make the maximum scope of application of temperature fuse can bring up to 3000W, adapted to air conditioner industry in recent years generally improves electrical auxiliary heater power in order to improve air conditioner heating effect in winter development trend fully.3, be provided with through hole on the surface of support, fuse is worn be placed in the through hole, even promptly can make the accurately variation of effective temperature of fuse, make the designs simplification of electric heater integral body again.4, support is meeting under the prerequisite of security performance, also provides possibility for saving the power supply link, and the manufacturing cost of heater is reduced.
