Description

Technical Field

[0001] This utility model relates to the field of relay technology, specifically a double-contact bridge-type spring-loaded contact relay. Background Technology

[0002] A single-bridge snap-action relay is an electrical control device with one or more movable contact bridges inside, each of which can control one circuit at the same time. It is simple in structure and easy to use.

[0003] However, the existing single-bridge snap-action relays still have shortcomings. Specifically, the existing single-bridge snap-action relays have no buffer when snapping, so under high load or frequent switching conditions, the contacts are prone to burning or sticking and aging faster, affecting the performance. Utility Model Content

[0004] The purpose of this invention is to provide a dual-contact bridge-type spring-loaded relay to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A double-contact bridge-type spring-loaded contact relay includes a base assembly. A moving contact mechanism is disposed inside the base assembly for connecting the main contact bridge. A spring is disposed inside the base assembly and above the moving contact mechanism. A main contact fastener is fixedly connected to the top of the base assembly. An outer cover is fixedly connected to the outer wall of the base assembly. A moving iron core is slidably connected inside the base assembly and below the moving contact mechanism. An electromagnetic device is fixedly connected inside the base assembly and near the moving iron core. A stationary contact is installed inside the base assembly and below the main contact fastener.

[0006] As a preferred embodiment of this utility model, the moving contact mechanism includes a contact seat slidably connected inside the base assembly. The contact seat is internally threaded with a self-tapping screw. Both sides of the outer wall of the contact seat are fixedly connected with spring pieces. A moving contact bridge is installed on the top of the contact seat and above the spring pieces. A washer is installed on the top of the moving contact bridge at the position corresponding to the self-tapping screw.

[0007] As a preferred embodiment of this utility model, the moving iron core has a T-shaped structure design, the spring is fixedly connected to the base assembly, and the shape of the outer cover is adapted to the shape of the base assembly.

[0008] Through the above technical solution, the spring reacts to the moving contact mechanism, buffering the force of the collision between the contacts. As a preferred embodiment of this utility model, the base assembly extends through and beyond the outer casing, and two sets of fasteners are provided for both the stationary contact and the main contact, with the stationary contact extending through the base assembly and beyond the main contact fasteners.

[0009] As a preferred embodiment of this utility model, the contact seat is designed with a cross shape, the spring is installed obliquely on the outer wall of the contact seat, and the self-tapping screw passes through the contact seat and extends to the outside of the moving contact bridge.

[0010] Through the above technical solution, the spring can push the moving contact bridge, so that the moving contact bridge is pushed towards the stationary contact with balanced force on both sides.

[0011] As a preferred embodiment of this utility model, the connection between the spring and the moving contact bridge is a fixed connection, and the gasket has a ring structure design.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes a double-contact bridge-type spring-loaded relay. The moving contact mechanism within this device connects the circuit. The coil receives an electrical signal, and the electromagnetic device generates magnetic force. Under this magnetic force, the moving iron core moves upward, connecting the moving iron core and the stationary contact. The main contact bridge is then connected. As the iron core moves, the spring reacts to the moving contact mechanism, buffering the impact force between the contacts and protecting them from strong impacts. The contact seat dissipates excess displacement of the moving iron core, and the spring pushes the moving contact, ensuring balanced force on both sides as it pushes towards the stationary contact. The double-contact design decomposes the impact of large currents, replacing the overheating phenomenon caused by high current in single-contact relays. This improves the product's electrical life and solves the problem of existing single-bridge snap-action relays lacking buffering during snap-action, leading to contact erosion or adhesion and faster aging under high loads or frequent switching, thus affecting performance.

[0018] As a preferred embodiment of this utility model, the moving contact mechanism 2 includes a contact seat 201 slidably connected inside the base assembly 1. The contact seat 201 is internally threaded with a self-tapping screw 202. Both sides of the outer wall of the contact seat 201 are fixedly connected with spring pieces 203. A moving contact bridge 204 is installed on the top of the contact seat 201 and above the spring pieces 203. A washer 205 is installed on the top of the moving contact bridge 204 at the position corresponding to the self-tapping screw 202.

[0019] As a preferred embodiment of this utility model, the moving iron core 6 is designed with a T-shaped structure, the spring 3 is fixedly connected to the base assembly 1, the spring 3 will react with the moving contact mechanism 2 to buffer the force of the collision between the contacts, and the shape of the outer cover 5 is adapted to the shape of the base assembly 1.
