Description

Technical Field

[0001] This utility model relates to the field of relay technology, and more specifically, to a relay with a modified frame. Background Technology

[0002] An electromagnetic relay is an electrical device that uses electromagnetic force to drive the relative movement of mechanical parts to produce a predetermined response. It generally consists of a magnetic circuit, a moving spring, and a stationary spring. In daily life, a relay with a modified frame is often needed.

[0003] In traditional relays, an electric arc is generated when the contacts close and open during operation. The high temperature and energy of the arc cause the contact material to melt and splatter everywhere. The splatter can easily form an "electric bridge" between disconnected circuits, thereby shortening the creepage distance and insulation distance that the relay should have. This can lead to relay malfunction, and in severe cases, it can even affect the safety of the relay, reduce its service life and practicality.

[0004] Therefore, those skilled in the art have provided a relay with an improved frame to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a relay with an improved frame, including a base, and further comprising:

[0006] The outer casing is fitted over the base.

[0007] The magnetic circuit assembly is disposed inside the base;

[0008] A moving spring assembly is disposed outside the magnetic circuit assembly;

[0009] A stationary spring assembly is disposed inside the base;

[0010] A barrier component is disposed outside the magnetic circuit assembly;

[0011] The dummy B-foot is fixedly installed inside the base.

[0012] As a further improvement to this technical solution, the magnetic circuit assembly includes a skeleton body fixedly installed inside the base. A coil is provided on the outside of the skeleton body. A mounting hole for installing an iron core is opened through the inside of the skeleton body. A yoke is provided on the outside of the skeleton body. A mounting groove for installing the yoke is opened inside the base. An armature is provided on the outside of the yoke. Two coil feet are fixedly installed inside the skeleton body. A guide groove for the coil feet to move is opened inside the base.

[0013] As a further improvement to this technical solution, the moving spring assembly includes a moving spring plate fixedly installed on the outside of the yoke and armature. The moving spring plate has two mounting holes for mounting moving contacts inside. The base has a mounting groove for mounting the spring plate foot inside. The moving spring plate is disposed between the spring plate foot and the yoke.

[0014] As a further improvement to this technical solution, the static spring assembly includes a foot A that is fixedly installed inside the base, and the foot A has two mounting holes for installing static contacts.

[0015] As a further improvement to this technical solution, the barrier component includes a retaining wall disposed outside the frame body.

[0016] As a further improvement to this technical solution, the outer shell and the base are fixedly installed by adhesive.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In this type of relay with an improved frame, the magnetic circuit assembly, moving spring assembly, stationary spring assembly, and blocking assembly are configured to generate an electromagnetic force when current flows through the coil. This attracts the armature, causing it to contact the pole face at one end of the iron core. This drives the moving contact of the moving spring assembly to close with the stationary contact of the stationary spring assembly. When the current in the coil disappears, the electromagnetic force also disappears, causing the armature to reset and separate from the pole face at one end of the iron core. This separates the moving contact of the moving spring assembly from the stationary contact of the stationary spring assembly. Thus, the contact or separation of the moving and stationary contacts achieves the purpose of switching the circuit on or off to connect or disconnect the external load. However, an electric arc is generated when the moving contact and the stationary contact close or open. The high temperature and energy of the arc cause the moving or stationary contact to melt and splatter everywhere. The splatter can easily form an "electrical bridge" between disconnected circuits. At this time, the blocking component can effectively block the "electrical bridge" formed by the splatter before the circuit is disconnected, thereby protecting the normal use of the relay. By setting the blocking component, not only can the original insulation distance of the relay be effectively increased, but the "electrical bridge" formed during the operation of the relay can also be blocked, effectively extending the service life of the relay and improving its practicality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4 As shown, this embodiment provides a relay with a modified frame, including a base 1, and further comprising:

[0027] The outer shell 2 is fitted over the base 1;

[0028] The magnetic circuit assembly is located inside the base 1;

[0029] The moving spring assembly is located outside the magnetic circuit assembly;

[0030] The stationary spring assembly is located inside the base 1;

[0031] The barrier component is located outside the magnetic circuit component;

[0032] The dummy B-foot 10 is fixedly installed inside the base 1.

[0033] The above working principle is as follows: When current flows through coil 4, an electromagnetic force is generated. At this time, armature 6 is attracted and comes into contact with the pole face at one end of iron core 11, thereby driving the moving contact 13 of the moving spring assembly to close with the stationary contact 14 of the stationary spring assembly. When the current in coil 4 disappears, the electromagnetic force disappears as well. At this time, armature 6 returns to its original position and separates from the pole face at one end of iron core 11, thereby separating the moving contact 13 of the moving spring assembly from the stationary contact 14 of the stationary spring assembly. Thus, by the contact or separation of the moving contact 13 and the stationary contact 14, the purpose of connecting or disconnecting the circuit of the external load is achieved. However, at the moving contact 13... An electric arc is generated when the moving contact 13 or the stationary contact 14 is closed or opened. The high temperature and energy of the arc cause the moving contact 13 or the stationary contact 14 to melt and splatter everywhere. The splatter can easily form an "electrical bridge" between the disconnected circuits. At this time, the blocking component can effectively block the "electrical bridge" formed by the splatter before the circuit is disconnected, thereby protecting the normal use of the relay. By setting the blocking component, not only can the original insulation distance of the relay be effectively increased, but the "electrical bridge" formed during the operation of the relay can also be blocked, effectively extending the service life of the relay and improving the practicality of the relay.

[0034] To enable the relay to function properly, the magnetic circuit assembly includes a frame body 3 fixedly installed inside the base 1. A coil 4 is located on the outside of the frame body 3. A mounting hole for mounting the iron core 11 is opened through the inside of the frame body 3. A yoke 5 is located on the outside of the frame body 3. A mounting groove for mounting the yoke 5 is opened inside the base 1. An armature 6 is located on the outside of the yoke 5. Two coil feet 12 are fixedly installed inside the frame body 3. A guide groove for the coil feet 12 to move is opened inside the base 1. When the magnetic circuit system needs to be installed, simply fix the frame body 3 inside the base 1. Then, fix the coil 4 and iron core 11. Next, install the yoke 5 and armature 6 on the outside of the frame, and fix the coil feet 12 inside the frame. This allows the magnetic circuit system inside the relay to be assembled, enabling the relay to function normally.

[0035] Considering that the moving spring assembly needs to be fixedly installed when using the relay, the moving spring assembly includes a moving spring 8 fixedly installed on the outside of the yoke 5 and armature 6. The moving spring 8 has two mounting holes for mounting the moving contact 13, and the base 1 has a mounting groove for mounting the spring foot 7. The moving spring 8 is located between the spring foot 7 and the yoke 5. Due to the arrangement of the moving spring 8, when current flows through the coil 4, an electromagnetic force is generated. At this time, the armature 6 will be attracted and contact the pole face of one end of the iron core 11. When the current in the coil 4 disappears, the electromagnetic force also disappears. At this time, the armature 6 resets and separates from the pole face at one end of the iron core 11, thereby separating the moving contact 13 inside the moving spring 8 from the stationary contact 14 inside the stationary spring assembly. At this time, the contact or separation between the moving contact 13 and the stationary contact 14 can achieve the purpose of connecting or disconnecting the circuit of the external load, thereby enabling the relay to work normally.

[0036] In order to enable the moving contact 13 to effectively close or separate from the stationary contact 14, the stationary spring assembly includes a foot A 9 fixedly installed inside the base 1. The foot A 9 has two mounting holes for mounting the stationary contact 14. Through the arrangement of the foot A 9 and the stationary contact 14, the moving contact 13 and the stationary contact 14 can be effectively closed or separated. Thus, the contact or separation between the moving contact 13 and the stationary contact 14 can achieve the purpose of connecting or disconnecting the circuit of the external load.

[0037] In order to effectively isolate the "electrical bridge" generated by splashing objects before the circuit is disconnected, the blocking component includes a baffle 15 set outside the frame body 3. By adding a baffle 15 outside the frame body 3, the original insulation distance of the relay can be effectively increased, and the "electrical bridge" formed during the operation of the relay can be effectively blocked. This protects the normal use of the relay, effectively extends the service life of the relay, and improves the safety factor and practicality of the relay during use.

[0038] In addition, to facilitate the installation of the base 1 and the outer shell 2, the outer shell 2 and the base 1 are fixed together with adhesive. When it is necessary to fix the base 1 and the outer shell 2 together, simply apply adhesive to the outside of the base 1 or the inside of the outer shell 2, and then put the outer shell 2 on the outside of the base 1. At this time, the base 1 and the outer shell 2 can be fixed and bonded together with adhesive.
