Abstract
Key protection relay protection device. Most relay protection device's jack all exposes in the air at present, when needs use, with the circuit plug jack in, because jack department does not have safeguard measure, make the interior dust that accumulates of jack easily to influence the use that external circuit is connected to the relay. The utility model discloses the constitution includes: relay protection device shell (1), relay protection device shell forward-mounted have display screen (2), button (3) and jack (4), relay protection device shell upper portion open and to have T type groove (10) and be connected with fixed plate (5), T type groove in the ann shielding plate (9) are equipped with, the fixed plate on be connected with spring (6), the spring other end and shielding plate connect, the shielding plate on install screw (8), baffle (7) have been arranged to shielding plate one side edge, the baffle lower part and relay protection device shell are connected. The utility model is used for button protection relay protection device.
Description
Technical Field
The utility model relates to a relay protection technical field, concretely relates to button protection relay protection device.
Background
The relay protection device is a device which can automatically trip a gate when a power element is in short circuit, overload and fault, and is a device for protecting the safety of our lives and properties. Most relay protection device exists and advances the dust easily, and present most relay protection device's jack all exposes in the air, when needs use, with the circuit insert jack in, because jack department does not have safeguard measure, makes the interior dust that accumulates of jack easily to influence the use that external circuit is connected to the relay.
Disclosure of Invention
The utility model aims at providing a button protection relay protection device.
The above purpose is realized by the following technical scheme:
a key protection relay protection device comprises: relay protection device shell, relay protection device shell forward-mounted have display screen, button and jack, relay protection device shell upper portion open and to have T type groove and be connected with the fixed plate, T type groove liam be equipped with the shielding plate, the fixed plate on be connected with the spring, the spring other end with the shielding plate connect, the shielding plate on install the screw, shielding plate one side edge arranged the locating plate, locating plate lower part with relay protection device shell connect.
The key protection relay protection device, the shielding plate be the L type, its lateral wall covers in button and jack upper portion, its upper wall bottom is connected with T type guide rail, T type guide rail insert relay protection device shell upper portion in the T type groove, the screw pass the T type guide rail of shielding plate.
Has the advantages that:
1. the utility model discloses a shielding plate can reduce the amount that the dust enters into the jack, makes the jack can not appear contact failure phenomenon when connecting plug-in components, and the button can not take place the mistake phenomenon of touching, ensures relay protection device to the reliability of the protection of external circuit, has improved the safety of circuit.
2. The utility model discloses relay protection device's button and jack do not do the during operation, and the shielding plate looses the screw through the screw fixation position on upper portion when jack connection plug-in components, outwards pulls out along T type groove with the shielding plate and removes workspace and locking screw fixed position, and the screw is loosened after the work is accomplished, and the shielding plate is stopped after being pulled back and contacting the locating plate under the effect of spring, and this protector simple structure is reliable, and the practicality is strong.
