Abstract
The utility model discloses a thermal insulation box for a double-temperature-switch lifespan testing machine, which realizes that an upper part and a lower part of a panel of a tested switch are in two temperature environments. The thermal insulation box comprises a baking oven (1), a box body (3) and a box cover (4). The box cover (4) is provided with at least one through hole (5) which is used for installing a tested switch (6) so that an upper part (6.1) of a panel of the tested switch (6) is in an indoor environment while a lower part (6.2) of the panel is in an environment in the box body (3). The box body (3) is provided with a temperature sensor (7) which is electrically connected with a control unit of the baking oven (1). The bottom of the box body (3) is provided with a plurality of ventilation holes (11) which enable the inside of the box body (3) to be communicated with a baking cavity (2).
Description
Technical field
The utility model relates to testing equipment technical field, is specifically a kind of insulation can of two temperature switch endurance testing machine.
Background technology
In order to realize the test of two temperature switch life, need to design a kind of insulation can of two temperature switch endurance testing machine, this insulation can requires upper and lower two parts of the panel that can realize Test Switchboard in two temperature environments, prior art only provides conventional insulation can, is not suitable for the test of two temperature switch life.
Utility model content
The technical problems to be solved in the utility model is that a kind of insulation can of the two temperature switch endurance testing machine of upper and lower two parts in two temperature environments of the panel that can realize Test Switchboard is provided.
The technical solution of the utility model is, the insulation can of the utility model two temperature switch endurance testing machine, it comprises baking oven, part or is all placed in the casing in the baking chamber of baking oven, covers the case lid of casing, case lid is provided with at least one through hole, this through hole for tested switch is installed so that the top of the panel of tested switch in indoor environment, and in the environment of the bottom of panel in casing, casing is provided with temperature sensor, this temperature sensor is electrically connected with the control module of baking oven; The bottom of casing is provided with some air vents so that box house is communicated with baking chamber.
Adopt after said structure, the utility model compared with prior art, have the following advantages: because it comprises baking oven, lower part or be all placed in the casing in the baking chamber of baking oven, cover the case lid of casing, case lid is provided with at least one through hole, this through hole for tested switch is installed so that the top of the panel of tested switch in indoor environment, and in the environment of the bottom of panel in casing, casing is provided with temperature sensor, this temperature sensor is electrically connected with the control module of baking oven, the bottom of casing is provided with some air vents so that box house is communicated with baking chamber, like this, can realize panel upper of Test Switchboard, lower two parts are in two temperature environments, in casing, initial warm-up period temperature rise is fast, temperature field stability and controllability are good, and the temperature in the baking chamber of baking oven can active accommodation, arrange as required, setting range is larger, comprehensively above-mentioned, the utlity model has panel upper that can realize Test Switchboard, the advantage of lower two parts in two temperature environments.
As improvement, when through hole is multiple, each through hole is sequentially uniformly distributed along casing left and right rectilinear direction, and like this, structure is more compact regular, the dismounting test of being more convenient for.
As improvement, 3/7ths height parts of casing are placed in the baking chamber of baking oven, temperature sensor is located on the right inside sidewall of casing, height apart from the inner bottom surface of casing is 2/3rds of right inside sidewall height, the homogeneity, stability and the controllability that are placed in the baking chamber of baking oven and the position of the temperature sensor temperature field to casing due to how many parts of casing are very key, said structure more can make the temperature of casing keep evenly, stablize, and the temperature that temperature sensor obtains is more conducive to baking oven and realizes the control to the temperature in casing.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The insulation can of the utility model two temperature switch endurance testing machine, it comprise baking oven 1, local or be all placed in the baking chamber 2 of baking oven 1 casing 3, cover the case lid 4 of casing 3, case lid 4 is provided with at least one through hole 5, this through hole 5 for tested switch 6 is installed so that the top 6.1 of the panel of tested switch 6 in indoor environment, and in the environment of the bottom 6.2 of panel in casing 3, casing 3 is provided with temperature sensor 7, and this temperature sensor 7 is electrically connected with the control module of baking oven 1; The bottom of casing 3 is provided with some air vents 11 so that casing 3 inside are communicated with baking chamber 2.
When through hole 5 is multiple, each through hole 5 is sequentially uniformly distributed along casing 3 left and right rectilinear directions.
3/7ths height parts of casing 3 are placed in the baking chamber 2 of baking oven 1, and temperature sensor 7 is located on the right inside sidewall of casing 3, are 2/3rds of right inside sidewall height apart from the height of the inner bottom surface of casing 3.
In this example, through hole 5 is three, in one line along casing 3 left and right rectilinear directions; Safeguard for the ease of dismounting, also increase tested switch installation board 8, on tested switch installation board 8, establishing hole exposes so that bottom 6.2 can be communicated with through hole 5, casing 3 for bottom 6.2, the temperature environment that realizes bottom 6.2 is identical with the temperature environment in casing 3, using method is first tested switch 6 to be arranged on tested switch installation board 8, then tested switch installation board 8 is fixed on case lid 4 by wing nut.
