Relay with reliable triggering

Technical Field

The utility model relates to a relay field, concretely relates to trigger reliable relay.

Background

In that

A relay is an electric control device that generates a predetermined step change in a controlled amount in an electric output circuit when a change in an input amount meets a predetermined requirement. It has an interactive relationship between the control system and the controlled system. It is commonly used in automated control circuits, which are actually a "recloser" that uses low current to control high current operation. The circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like. The existing relay mainly comprises a coil, an iron core and the like, and the iron core is used as an execution action unit of the relay and needs to frequently act, so that the reliable action of the iron core and accessories is the concrete embodiment for measuring the reliability of the relay. The iron core of the existing relay mainly resets by a spring arranged at the upper end when resetting, for example, in a relay patent with the publication number of CN202839474U, the iron core of the relay mainly resets by the spring arranged at the upper end after action, but in a specific assembling process, the spring arranged in a sleeve is unstable and easy to fall off, so that the installation is difficult, and in the using process, the spring is arranged in the relay seat, once a fault is difficult to find, the relay needs to be completely disassembled, so that the maintenance is difficult.

Furthermore, the two sides of the contact reed are provided with insulating sheets, the insulating sheets are sleeved on the outer side of the iron core, the iron core is sleeved with an insulating seat, the contact reed is embedded and sleeved on the outer side of the insulating seat, and the iron core is provided with a prismatic table for limiting the movement of the contact reed; the advantage can realize the insulating setting of contact reed and iron core through the insulating seat that sets up, improves the utility model discloses a reliability avoids the action in-process to make the iron core electrified.

Furthermore, the lower end part of the iron core is provided with a fixed groove, a baffle is arranged in the fixed groove, and two ends of the compression spring are respectively abutted against the insulating plate and the baffle; the contact reed pressing device has the advantages that the pressing spring can reliably press the contact reed through the arranged baffle, the contact reed is reliably contacted with the wiring terminal in the action process, and the phenomenon of poor contact is avoided.

Furthermore, the baffle is integrally provided with a baffle ring, one end of the compression spring is arranged in the baffle ring, the iron core is movably sleeved with a sleeve seat, and the other end of the compression spring is arranged in the sleeve seat and is abutted against the sleeve seat; the advantage is that can make pressure spring's end fixing through the setting of cover seat and fender ring, avoids leading to compressing tightly the dynamics because of the removal of pressure spring tip and appearing the deviation, leads to electrocute the reed appear when the action with binding post bad contact's phenomenon.

Compared with the prior art, the utility model has the advantages of ensure the reliable actuation or the disconnection of iron core when can realizing the relay action through the reset spring that sets up and the setting of limiting plate, make iron core actuation back compress tightly the contact reed through pressure spring promptly and make metal contact and binding post reliably compress tightly, make the iron core reliable rapidly with metal contact and binding post separation disconnection through reset spring cooperation limiting plate when the disconnection, improve the utility model discloses a reliability, and the cooperation through spacing platform and limiting plate can with the utility model discloses insert and establish and to use on the relay mount pad, rather than traditional a plurality of complicated part cooperations iron cores that just can reset. Because the utility model discloses a main spare part sets up in the outside of relay mount pad, as shown in fig. 4, consequently makes the utility model discloses an installation action of iron core or spare part is more directly perceived, and the installation of being convenient for is maintained, and when breaking down promptly, the operator can audio-visually see out iron core and complex spare part when whether break down.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

The utility model provides a trigger reliable relay, includes iron core 1 and contact reed 2, and 2 movable sleeves of contact reed are established the lower tip of iron core 1 is fixed and is provided with metal contact 2.1 on the contact reed 2, the lower extreme of iron core 1 is provided with pressure spring 3 that is used for compressing tightly contact reed 2, and 1 covers of iron core is equipped with reset spring 4, and reset spring 4 overlaps and is located the top of contact reed 2, and 1 movable sleeve of iron core is equipped with limiting plate 5, reset spring 4's both ends offset with contact reed 2, limiting plate 5 respectively, and iron core 1 still is provided with the spacing platform 6 that is used for preventing the slippage of limiting plate 5. Both sides of above-mentioned contact reed 2 all are provided with insulating piece 7, and insulating piece 7 cover is established the outside of iron core 1, 1 movable sleeve of iron core is equipped with insulating seat 8, and contact reed 2 cover sets up the outside of insulating seat 8, iron core 1 are provided with the terrace with edge 9 that is used for restricting contact reed 2 and removes.
