Abstract
The utility model is suitable for a membrane switch tests technical field, provides a container for membrane switch surveys waterproof test, including holding water tank, be divided into a plurality of test areas in the holding water tank, there is the metal air cavity in every test area, the air cock has been arranged on metal air cavity surface, holding water tank lateral wall have with the air inlet of metal air cavity intercommunication, holding water tank inner wall still is equipped with heating device. This container can generate the continuous bubble and strike membrane switch, and can adjust the temperature through heating device, can be so that membrane switch is in a comparatively harsh test environment, and is more strict to waterproof nature test condition, is favorable to improving membrane switch product quality, carries membrane switch's life.
Description
Technical Field
The utility model belongs to membrane switch test field especially relates to a container that is used for membrane switch to survey waterproof test.
Background
The membrane switch is a flexible switch panel exposed outside the electric appliance, has low cost and long service life, and is widely applied in the field of electric equipment.
The waterproof test of the membrane switch is a key process for verifying whether the product is qualified. Generally, before mass production of membrane switches, small-lot production of membrane switches is performed, and then a waterproof test is performed. The current test protocol is: the membrane switch is implanted into the water container, and after a certain time, the membrane switch is taken out and aired, and then the membrane switch is electrified to verify whether the membrane switch can be normally used. However, the existing container has a simple structure, is similar to a common water tank, has a mild environment, and cannot accurately reflect the quality of the membrane switch according to a test result.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, an object of the present invention is to provide a container for testing water resistance of a membrane switch, which aims to solve the above technical problems.
The utility model adopts the following technical scheme:
the utility model provides a container for membrane switch surveys waterproof test, includes water containing tank, be divided into a plurality of test areas in the water containing tank, there is the metal air cavity in every test area, the air cock has been arranged on metal air cavity surface, water containing tank lateral wall have with the air inlet of metal air cavity intercommunication, water containing tank inner wall still is equipped with heating device.
Furthermore, a circle of limiting rods are arranged at the top of each metal air cavity.
Furthermore, the heating device is a serpentine heating pipe, and two ends of the serpentine heating pipe are provided with connectors.
Furthermore, a circle of reinforcing plate is arranged on the periphery of the water containing tank, and a rib plate is arranged between the reinforcing plate and the water containing tank.
The utility model has the advantages that: this device can generate continuous bubble impact membrane switch in the container, and can adjust the temperature through heating device, can be so that membrane switch is in a comparatively harsh test environment, and is more strict to waterproof nature test condition, is favorable to improving membrane switch product quality, improves membrane switch's life.
Drawings
Fig. 1 is a structural diagram of a container for testing water resistance of a membrane switch according to an embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to explain the technical solution of the present invention, the following description is made by using specific examples.
As shown in fig. 1, the container for waterproof test is surveyed to membrane switch that this embodiment provided, including water containing tank 1, be divided into a plurality of test zones in the water containing tank 1, there is metal air cavity 2 in every test zone, air cock 3 has been arranged on metal air cavity 2 surface, water containing tank 1 lateral wall have with the air inlet 6 of metal air cavity 2 intercommunication, water containing tank 1 inner wall still is equipped with heating device 4.
In the structure, a circle of limiting rods 7 are arranged at the top of each metal air cavity 2. In the figure, the limiting rod 7 consists of a middle rod and front and rear side plates, the middle rod is connected between the front and rear side plates, and the front and rear side plates are both provided with openings, so that water flow is not obstructed. A metal air cavity is arranged between two adjacent middle rods. The metal air cavity has certain bearing capacity.
During the use, put into a plurality of test frames with the membrane switch of small batch volume, put into every test frame on the metal air cavity to, aerify through the air pump of air inlet, form the membrane switch that strikes bubble inflation test frame for membrane switch can roll in test frame. Simultaneously, further steerable heating device heats the container water-logging, for example the temperature can be set for 60 degrees centigrade, heating device 4 is snakelike heating pipe, there is connector 41 snakelike heating pipe both ends. The test container provided by the embodiment has a harsh test environment, and can provide a test basis for the waterproof performance of the membrane switch under a high-temperature environment and a turning condition.
Furthermore, a circle of reinforcing plate 5 is arranged on the periphery of the water containing tank 1, and a rib plate 11 is arranged between the reinforcing plate 5 and the water containing tank 1 so as to improve the integral firmness of the container.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
