Technical field

The utility model relates to the starter technical field of use in refrigerator, and the PTC sheet that especially a kind of refrigerator starter is used is prevented the shorting clip locking structure.

Background technology

At present, existing refrigerator starter structure, its PTC thermosensitive resistor film generally clamps through the intermediate plate that extends on the and arranged on left and right sides conduction inserted sheet and conducts electricity; But because the PTC thermosensitive resistor film has certain useful life, when fracture takes place the PTC thermosensitive resistor film, because intermediate plate all has certain elasticity; The intermediate plate of one side just maybe the conduction inserted sheet of bullet to opposite side on and contact; Just be short-circuited easily, even the appearance of spark is arranged, cause the generation of fire.

Summary of the invention

The purpose of the utility model is to solve the deficiency of above-mentioned prior art, and provides a kind of simple and reasonable for structure, and the PTC sheet that refrigerator starter safe in utilization is used is prevented the shorting clip locking structure.

The utility model solves the technical scheme that its technical problem adopted: the PTC sheet that a kind of refrigerator starter is used is prevented the shorting clip locking structure; Comprise the starter housing; Vertical plug-in type is fixed with the PTC sheet on the starter housing; The left and right side of PTC sheet and upside are taken up in order of priority and fixedly are plugged with first, second and third conduction inserted sheet, and the first conduction inserted sheet is connected with N utmost point tension disc, it is characterized in that; The and arranged on left and right sides end face of said corresponding PTC sheet first and second the conduction inserted sheet on respectively left and right sides array be extended with the left and right shell fragment of the V-type with cavity that compresses the both sides end face; The left and right shell fragment of V-type is formed by the support plate of cavity base plate and the extension along cavity base plate both sides, and the cavity base plate of V-type left side shell fragment compresses PTC sheet left end face, and it is affixed that its two support plates end extends to the first conduction inserted sheet; The cavity base plate of the right shell fragment of V-type is fixed on the second conduction inserted sheet, and its two support plates end extends to PTC sheet its right end face and compresses and offsets; Adopt the anti-shorting clip locking structure of PTC sheet of this structure, left and right shell fragment is arranged to V-type, all have cavity on the left and right shell fragment of V-type; And the left and right shell fragment of V-type divides another name array to be welded on first and second conduction inserted sheet; But the contact distance between the left and right shell fragment of V-type is increased, so after even the PTC sheet breaks, the V-type of side left side shell fragment can not contact with the right shell fragment of the V-type of opposite side; Avoid short circuit and breaking out of fire, the fail safe that effectively improves starter.

The utility model can also adopt following technical measures to solve: as improvement further, and the also limit-type fore-set that is equipped with the L type of forward and backward profile end face of said PTC sheet; The fore-set of said L type plays position-limiting action to the PTC sheet, the convenient installation and transportation.

The cavity base plate of said V-type left side shell fragment is provided with boss, and boss and PTC sheet left end face offset.

Two support plate ends of the right shell fragment of said V-type are provided with the arc bending joint portion, and the arc bending joint portion is provided with boss, and boss and PTC sheet its right end face offset.

Said starter housing is fastened by starter top shell and starter drain pan each other to be formed.

The beneficial effect of the utility model is: the PTC sheet that the refrigerator starter of the utility model is used is prevented the shorting clip locking structure; It is simple and reasonable for structure, and left and right shell fragment is arranged to V-type, all has cavity on the left and right shell fragment of V-type; And the left and right shell fragment of V-type divides another name array to be welded on first and second conduction inserted sheet; But the contact distance between the left and right shell fragment of V-type is increased, so after even the PTC sheet breaks, the V-type of side left side shell fragment can not contact with the right shell fragment of the V-type of opposite side; Avoid short circuit and breaking out of fire, the fail safe that effectively improves starter.
