The tripping device includes an electromagnetic tripping device, a compound tripping device, an electronic tripping device, etc. The principle of the electromagnetic release is that when the current is large enough, the generated magnetic field force overcomes the reaction force spring and attracts the armature to hit the traction rod, thereby driving the mechanism to act, cutting off the circuit, and playing a protective role. However, the existing release on the market has a complex structure and complex assembly, which greatly reduces the production efficiency of the release. Meanwhile, in the existing tripping device on the market, both ends of the coil assembly are electrically connected to the circuit board through the lead wire, but the joint is easily broken through the lead wire connection, which causes the tripping device to lose its due function and reduces the overall reliability of the tripping device.

In view of the shortcomings of the existing technology, this.Technical StaffA new type of release with simple structure, convenient assembly and good reliability is provided. In order to achieve the above objectives,The release is usedThe following technical solutions: A new type of trip device includes a body. The body includes a hollow housing assembly and a trip device located in the housing assembly. The trip device includes a magnetizer, a coil assembly, and permanent magnet assemblies located at both ends of the magnetizer. The upper side of the coil assembly is provided with an armature matched with the magnetizer, and a push rod matched with the armature is provided on the armature. The coil assembly includes a coil frame and a coil winding sleeved on the coil frame. The lower end of the coil frame is provided with a wiring part fixedly connected to the coil frame, and the wiring part is provided with two fixed connections to the coil winding.LThe permanent magnet assembly includes a permanent magnet and a support member matched with the permanent magnet, one end of the support member is matched with the armature, and the support member is also connected with the armature through a tension spring. The release includes a magnetic conductor, a coil assembly, and permanent magnet assemblies located at both ends of the magnetic conductor. The structure is simpler, the assembly complexity is reduced, and the production efficiency of the release is improved.Lshaped pin,LThe shaped pins are electrically connected to the coil winding respectively, which can effectively avoid the problem that the existing lead wires are easily broken when connected, and ensure the overall reliability of the trip device. The armature is provided with a limit groove matched with the support, the two ends of the support are provided with limit lugs matched with the limit groove, and the support is also provided with an integrated fixing protrusion, and the fixing protrusion and the armature are both Provided with a hanging hole matched with the tension spring. The position of the armature is offset by the matching of the limit notch and the limit convex strip, the fixed convex is convenient for the bracket and the armature to be connected through the tension spring, and the hanging hole is convenient for the installation of the tension spring. The armature is provided with a limit protrusion matched with the limit notch, the limit protrusion and the upper end of the magnetizer are tightly connected to each other, and one side of the limit protrusion is provided with a limit chamfer matched with the limit convex strip. The limit protrusion acts as a fulcrum when the armature moves, which is convenient for the armature to rotate, and the limit chamfer is convenient for the limit notch and the limit protrusion to cooperate with each other.

To sum up,The above releaseThe beneficial effects are: the release includes a magnetizer, a coil assembly, and permanent magnet assemblies located at both ends of the magnetizer, the structure is simpler, the complexity of assembly is reduced, and the production efficiency of the release is improved;LThe type pin effectively avoids the problem that the existing lead is easy to break when connecting, and ensures the overall reliability of the release.
