Description

Novel socket trip gear

Technical field

The utility model discloses a kind of novel socket trip gear, and it is used for the socket socket, and the electrical appliance that is plugged in the socket is shielded.

Background technology

In daily life and the industrial production, a lot of electrical appliances are electrically connected with power supply by socket, though a lot of electrical appliances itself have electric leakage, overcurrent, protective devices such as anti-electric wall, but when its ground connection is broken down or the protective device of electrical appliance itself when losing efficacy, if in the socket this moment protective device is not set, and the breaker protection electric current of distribution box is bigger, electrical appliance is easy to damage like this, therefore, the inventor has developed a kind of earth leakage circuit-breaker trip gear, with reference to figure 1 and Fig. 2, comprise drain pan 1 ', electromagnetic mechanism 2 ', movable contact spring 31 ', 32 ', static contact 41 ', 42 ', dropout plate 5 ' and pull bar 6 ', wherein drain pan 1 ' is used for fixing and supports other each part, its top and a side are provided with opening, electromagnetic mechanism 2 ' is located on the drain pan 1 ', and the bottom of pull bar 6 ' and dropout plate 5 ' fastens or separate contacting or separate with realization movable contact spring and static contact; The dropout plate 5 ' structure that is formed in one, one side of dropout plate 5 ' fore-and-aft direction is buckled in the effect end of electromagnetic mechanism 2 ' for the U-shaped structure, dropout plate 5 ' another side has Yi Katai to be used for colluding to buckle with the barb of pull bar 6 ' bottom closing or separating, and stretches out on the dropout plate 5 ' left and right directions and support the contact end of movable contact spring; Movable contact spring and static contact correspondence are set to left and right two groups, left and right movable contact spring 31 ', 32 ' contact end press in the extension 53 ', 54 ' of the dropout plate 5 ' left and right sides, when pull bar 6 ' and dropout plate 5 ' fasten and upwards move, dropout plate 5 ' drives movable contact spring and together makes progress, and makes the contact end of dynamic and static contact be communicated with the formation closed-loop path; Electromagnetic mechanism 2 ' comprises iron core 21 ', one end and dropout plate 5 ' snapping, the other end links to each other with switch connecting rod 7 ', and switch connecting rod 7 ' is a ramp structure 70 ' with iron core 21 ' contact jaw, promoting iron core 21 ' downwards when the switch connecting rod moves moves backward, thereby iron core 21 ' moves after moving and driving dropout plate 5 ', and dropout plate 5 ' is separated with pull bar 6 ', and movable contact spring restores to the original state under the elastic force effect and static contact contact end disconnects; Also be provided with circuit board on the drain pan 1 ', switch connecting rod 7 ' and pull bar 6 ' pass circuit board and electromagnetic mechanism 2 ' or dropout plate 5 ' and have an effect, and circuit board is provided with leakage protection circuit.7 ' end of switch connecting rod connects the OFF button, pull bar 6 ' top connects the ON button and is called reset button again, also be provided with testing button between above-mentioned two buttons, on this testing button and the circuit board leakage protection circuit be electrically connected whether be used to detect leakage protection circuit working properly; Its operation principle is as follows: press lower link 6 ' by reset button by (ON button), after decontroling finger on earth, pull bar under the effect of pull-rod spring to rising to the bait and tangling dropout plate 5 ', the dropout plate is moved upward, and the movable contact spring that drives its both sides up contacts the movable contact spring on it with static contact, realizes the state that resets; When pressing release knob (OFF button), the hypotenuse structure of its bottom and iron core one end in contact also promote iron core and step back together with the dropout plate, and the barb of pull bar is colluded less than the dropout plate, thereby realize the action of threading off; When pressing testing button, leakage protection circuit makes electromagnetic mechanism work, and iron core 21 ' moves axially dropout plate 5 ' is removed from pull bar, and drives on the movable contact spring on its both sides movable contact spring and separate with static contact and realize threading off.The known earth leakage circuit-breaker trip gear of this kind part that still has some deficits: structure is comparatively complicated, and the parts that are fixed on the drain pan are more, and difficulty is bigger in the assembling process, and assembling is wasted time and energy; Being connected of lead and this trip gear adopted traditional wire casing fixed form on the other hand, and the wire casing parts are more, assembling and be connected trouble.

The utility model content

At the deficiencies in the prior art, the utility model provides a kind of simple in structure, assembling and all novel very easily socket trip gear of wiring.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of novel socket trip gear, comprise drain pan, loam cake, circuit board, instrument transformer, static contact, movable contact spring and trip gear, described loam cake is covered on the drain pan, instrument transformer is fixedly arranged on the drain pan, circuit board is located on the drain pan, and trip gear is located between drain pan and the circuit board, and described static contact and movable contact spring are located on the drain pan, described drain pan is one-body molded to be made, and described trip gear comprises electromagnetic mechanism and is located at testing button and reset button on the electromagnetic mechanism.

Above-mentioned novel socket trip gear, described drain pan are provided with at least two and are used for the screw hole of fixedlying connected with socket.

Above-mentioned novel socket trip gear, described instrument transformer are located at that adjacent with reset button on circuit board side.

Above-mentioned novel socket trip gear, described static contact and movable contact spring are welded to connect with an end of lead respectively, and the other end of each lead extends to the drain pan outside.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: because drain pan adopts integrated mode, each part of other of trip gear can be fixed on the drain pan easily like this, assembles very convenient; Be emerging in and have only reset button and testing button on the socket panel, panel is more succinct; By instrument transformer being located at the reset button sides adjacent, can make reset button and testing button be positioned at socket panel lateral middle like this, panel layout is attractive in appearance rationally; By lead movable contact spring, static contact are extended to the drain pan outside, the feasible like this work that the utility model is assembled in the socket is convenient.
