Description

Technical Field

[0001] The present invention relates to the technical field of relays, and more particularly to a push rod relay. Background Art

[0002] Relay contact bounce refers to the phenomenon that the relay contacts make multiple instantaneous contacts and separate due to factors such as electromagnetic induction and mechanical shock during the closing or opening process.

[0003] Arcs often occur between relay contacts, which will burn the relay contacts and surrounding parts. Contact bounce will cause the relay to connect and disconnect for a longer time. Longer arcing will increase the possibility of contact erosion and even produce secondary arcing, reducing the service life of the relay.

[0004] Therefore, how to solve the problem of frequent contact bounces in existing relays is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a push rod relay which can reduce the rebound of the moving reed.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A push rod relay comprises a base, a static spring piece vertically arranged on the base, a dynamic spring piece and a magnetic circuit drive component, and also comprises a transmission component arranged between the dynamic spring piece and the magnetic circuit drive component. The magnetic circuit drive component attracts the transmission component to make the transmission component swing. The transmission component drives the dynamic spring piece to move in the swinging state, so that the dynamic spring piece contacts or separates from the static spring piece. The dynamic spring piece is provided with a bent spring piece for slowing down the bouncing effect of the dynamic spring piece, and the transmission component is provided with a push plate cooperating with the bent spring piece.

[0008] Preferably, the movable spring piece is a bent structure with an inclination, and one end of the movable spring piece away from the base is inclined toward a direction close to the push plate.

[0009] Preferably, one end of the movable spring sheet away from the base is bent toward the push plate to form an elastic laminate that partially overlaps with the movable spring sheet, and a bent spring sheet is provided on the elastic laminate.

[0010] Preferably, the elastic laminate is provided with a bent spring sheet with an opening facing the base, and the bent spring sheet is arranged at an acute angle with the elastic laminate.

[0011] Preferably, the elastic laminate is provided with a bent spring sheet with an opening facing away from the base, and the bent spring sheet is arranged at an acute angle to the elastic laminate.

[0012] Preferably, limiting grooves are provided on both sides of the middle part of the movable spring piece.

[0013] Preferably, the moving spring sheet and the elastic laminate are provided with mounting holes for mounting the moving contact, the mounting hole is located in the middle of the elastic laminate, the bent spring sheet is located at the top of the mounting hole, and the static spring sheet is provided with a static contact corresponding to the moving contact.

[0014] Preferably, the transmission assembly includes a push rod and an armature, the armature is an inverted L-shaped structure, one end of the armature is swingably disposed on the push rod, and the other end of the armature is rotationally connected to the magnetic circuit drive assembly through a compression spring.

[0015] Preferably, a push plate is provided at one end of the push rod close to the moving spring sheet, and pluggable plug-in parts arranged in the limit groove are provided on both sides of the push plate. The middle bottom end of the push rod is slidingly connected with the middle of the base, and a positioning groove for inserting the armature is provided at the end of the push rod away from the moving spring sheet, and the push rod is swingably arranged in the positioning groove.

[0016] Preferably, the magnetic circuit driving assembly includes a driving coil and a yoke, and the armature is swingably disposed at the top end of the yoke.

[0017] The push rod relay provided by the present invention comprises a static spring piece, a dynamic spring piece and a magnetic circuit driving component vertically arranged on a base, and also comprises a transmission component arranged between the dynamic spring piece and the magnetic circuit driving component. The magnetic circuit driving component attracts the transmission component to make the transmission component swing. The transmission component drives the dynamic spring piece to move in the swinging state, so that the dynamic spring piece contacts or separates from the static spring piece. Through the electromagnetic action of the magnetic circuit driving component, the transmission component pushes the dynamic spring piece, forcing the dynamic spring piece to deviate from the initial position and be compressed, and generate a certain bending deformation in the direction opposite to the magnetic circuit driving component, so that the dynamic spring piece contacts with the static spring piece, and the dynamic spring piece contacts with the static spring piece. The movable spring sheet forms a rebound potential energy when released. When the magnetic circuit driving component is powered off, the transmission component loses the electromagnetic force attracted by the magnetic circuit driving component. The movable spring sheet rebounds under the action of the rebound potential energy, so that the movable spring sheet is separated from the static spring sheet. The movable spring sheet is provided with a bent spring sheet for slowing down the bouncing effect of the movable spring sheet. The transmission component is provided with a pushing plate cooperating with the bent spring sheet. When the electromagnetic attraction weakens and the rebound potential energy of the passive spring sheet is overcome, the movable spring sheet rebounds to one side of the magnetic circuit driving component. Through the contact between the bent spring sheet and the pushing plate, the pushing plate can quickly absorb the potential energy of the rebound of the movable spring sheet, play a buffering role, and thus reduce the rebound of the movable spring sheet.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] It should be noted that the directional words such as "upper" and "lower" mentioned below are defined based on the drawings in the specification.

[0037] In the relay structure, especially the push rod relay structure, the attraction between the moving contact of the moving assembly and the static contact of the static spring assembly is achieved by the armature pushing the moving spring under the action of electromagnetic attraction. During the electromagnetic attraction process, the flipping action of the armature is converted into a pushing action on the moving spring, forcing the moving spring to deviate from the initial position and be compressed, and produce a certain bending deformation in the direction opposite to the armature, forming a rebound potential energy when released. When the electromagnetic attraction weakens and the rebound potential energy of the passive spring is overcome, the moving spring rebounds to the side of the armature. Under the influence of the deformation and rebound of the moving spring and the inertia of the moving contact, a large rebound and anti-rebound swing will occur toward one side of the magnetic circuit part. In the process of anti-rebound, it is easy to cause a secondary connection between the moving contact and the static contact that is not technically required and affects the life of the relay (ablation phenomenon).

[0038] The core of the present invention is to provide a push rod relay, by arranging a bent spring piece 31 on the moving spring piece 3, through the contact between the bent spring piece 31 and the push plate 51, to resist the moving spring piece 3, absorb the kinetic energy of the moving spring piece 3 moving in the opposite direction, play a buffering role, reduce the amplitude of the moving spring piece 3, can reduce the rebound of the moving spring piece 3, reduce the possibility of contact erosion, and increase the service life of the relay.

[0039] Please refer to Figure 1 and Figure 2A push rod relay includes a base 1, a static spring piece 2, a dynamic spring piece 3 and a magnetic circuit driving component 4 vertically arranged on the base 1, and also includes a transmission component 5 arranged between the dynamic spring piece 3 and the magnetic circuit driving component 4. The magnetic circuit driving component 4 attracts the transmission component 5 to make the transmission component 5 swing. The transmission component 5 drives the dynamic spring piece 3 to move in the swinging state, so that the dynamic spring piece 3 contacts or separates from the static spring piece 2. Through the electromagnetic action of the magnetic circuit driving component 4, the transmission component 5 pushes the dynamic spring piece 3, forcing the dynamic spring piece 3 to deviate from the initial position and be compressed, and a certain bending deformation is generated in the direction opposite to the magnetic circuit driving component 4, so that the dynamic spring piece 3 contacts with the static spring piece 2, and the dynamic spring piece 3 The rebound potential energy during release is formed. When the magnetic circuit driving component 4 is powered off, the transmission component 5 loses the electromagnetic force attracted by the magnetic circuit driving component 4. The movable spring 3 rebounds under the action of the rebound potential energy, so that the movable spring 3 is separated from the static spring 2. The movable spring 3 is provided with a bent spring piece 31 for slowing down the bouncing effect of the movable spring 3. The transmission component 5 is provided with a pushing plate 51 cooperating with the bent spring piece 31. When the electromagnetic attraction weakens and the rebound potential energy of the passive spring 3 is overcome, the movable spring 3 rebounds to one side of the magnetic circuit driving component 4. Through the contact between the bent spring piece 31 and the pushing plate 51, the pushing plate 51 can quickly absorb the rebound potential energy of the movable spring 3, play a buffering role, and thus reduce the rebound of the movable spring 3.

[0040] Under the premise of not affecting the lateral pushing action of the push plate 51 between the armature 53 and the moving spring piece 3, the push plate 51 is formed in a flat plate structure in the vertical direction, which will not affect the lateral pushing action of the push plate 51 on the moving spring piece 3, and can effectively limit the release rebound of the moving spring piece 3 during the switching process, and prevent the moving spring piece 3 from rebounding during the release process and causing secondary connection between the moving contact 6 and the static contact 7. The top of the push plate 51 is higher than the top of the moving spring piece 3, so that the plate body of the push plate 51 is horizontally placed between the moving spring piece 3 and the magnetic circuit driving component 4, which has the effect of increasing the creepage distance and insulation isolation, and is safer and more reliable.

[0041] With the push rod relay arranged in the above manner, during the release process of the relay, the movable spring piece 3 can contact the push plate 51 through the bent spring piece 31 on itself, playing a buffering role, thereby reducing rebound.

[0042] In the above embodiment, the movable spring piece 3 is a bent structure with an inclination, and one end of the movable spring piece 3 away from the base 1 is inclined toward the direction close to the pushing plate 51 .

[0043] It should be noted that the bottom end of the movable spring piece 3 can be fixed on the base 1, and the end away from the base 1 is inclined toward the direction close to the pushing plate 51, and the middle part of the movable spring piece 3 is connected through the transmission component 5, so that the transmission component 5 can transmit the electromagnetic force of the magnetic circuit driving component 4 to the movable spring piece 3 to push the movable spring piece 3 to move.

[0044] In the above situation, one end of the movable spring piece 3 away from the base 1 is bent toward the pushing plate 51 to form an elastic laminate 32 partially overlapping with the movable spring piece 3 , and a bent spring piece 31 is provided on the elastic laminate 32 .

[0045] It can be understood that the elastic laminate 32 is provided on the movable spring 3, and the bent spring 31 is provided on the elastic laminate 32. The bent spring 31 partially collides with the push plate 51 on the transmission assembly 5 during the release process, and the elasticity of the bent spring 31 itself is used to absorb the collision energy, so that the movable spring 3 reduces the bounce. The movable spring 3 in the present application is composed of a plurality of springs stacked together, and can be elastically deformed and offset under pressure.

[0046] Please refer to Figure 3 and Figure 4 The elastic laminate 32 is provided with a bent spring piece 31 with an opening toward the base 1, and the bent spring piece 31 and the elastic laminate 32 are arranged at an acute angle. A shock-absorbing structure with an opening facing downward is formed between the bent spring piece 31 and the moving spring piece 3, and an acute angle is formed between the bent spring piece 31 and the moving spring piece 3. When the transmission component 5 is attracted and swung by the magnetic circuit driving component 4, it pushes the moving spring piece 3 to move, so that the moving spring piece 3 contacts the static spring piece 2. When the magnetic circuit driving component 4 is powered off, the transmission component 5 loses the electromagnetic force attracted by the magnetic circuit driving component 4, and the moving spring piece 3 rebounds under the action of the rebound potential energy. Through the contact between the bent spring piece 31 and the push plate 51, the push plate 51 can quickly absorb the rebound potential energy of the moving spring piece 3, play a buffering role, and thus reduce the rebound of the moving spring piece 3.

[0047] Please refer to Figure 5 and Figure 6 The elastic laminate 32 is provided with a bent spring piece 31 with an opening facing away from the base 1, and the bent spring piece 31 and the elastic laminate 32 are arranged at an acute angle. A shock-absorbing structure with an opening facing upward is formed between the bent spring piece 31 and the moving spring piece 3, and an acute angle is formed between the bent spring piece 31 and the moving spring piece 3. When the transmission component 5 is attracted and swung by the magnetic circuit driving component 4, it pushes the moving spring piece 3 to move, so that the moving spring piece 3 contacts the static spring piece 2. When the magnetic circuit driving component 4 is powered off, the transmission component 5 loses the electromagnetic force attracted by the magnetic circuit driving component 4, and the moving spring piece 3 rebounds under the action of the rebound potential energy. Through the contact between the bent spring piece 31 and the push plate 51, the push plate 51 can quickly absorb the rebound potential energy of the moving spring piece 3, play a buffering role, and thus reduce the rebound of the moving spring piece 3.

[0048] On the basis of the above two embodiments, the length of the bent spring piece 31 of the first embodiment is much greater than the length of the bent spring piece 31 of the second embodiment, and the shock absorbing effect is better.

[0049] On the basis of the above-mentioned embodiment, limiting grooves 33 are provided on both sides of the middle part of the movable spring piece 3 .

[0050] It should be noted that the limiting groove 33 is used to connect with the transmission assembly 5 so that the transmission assembly 5 can push the movable spring 3 to move under the driving of the electromagnetic force of the magnetic circuit driving assembly 4 .

[0051] In the above embodiment, a mounting hole 34 for mounting the moving contact 6 is provided on the moving spring sheet 3 and the elastic laminate 32, the mounting hole 34 is located in the middle of the elastic laminate 32, the bent spring sheet 31 is located at the top of the mounting hole 34, and a static contact 7 corresponding to the moving contact 6 is provided on the static spring sheet 2.

[0052] It can be understood that the static contact 7 is riveted into the mounting hole 34 of the static reed piece 2 , and the moving contact 6 is riveted into the mounting hole 34 of the moving reed piece 3 .

[0053] As a preferred embodiment, the transmission assembly 5 includes a push rod 52 and an armature 53. The armature 53 is an inverted L-shaped structure. One end of the armature 53 is swingably disposed on the push rod 52, and the other end of the armature 53 is rotationally connected to the magnetic circuit drive assembly 4 through a compression spring 54.

[0054] It should be noted that the armature 53 and the magnetic circuit drive assembly 4 can be rotated together through the compression spring 54. The bottom of the static spring piece 2 has a guide pin end that penetrates the bottom of the base 1, so that the static spring piece 2 can be installed and connected with the circuit board through the guide pin end. When the driving coil 41 of the magnetic circuit drive assembly 4 is energized, the armature 53 will push the push rod 52 to move under the drive of the electromagnetic force, and the dynamic spring piece 3 will achieve conductive contact with the static spring piece 2 under the drive of the push rod 52 to increase the contact force between the dynamic and static contacts.

[0055] Please refer to Figure 7 A push plate 51 is provided at one end of the push rod 52 close to the movable spring sheet 3, and pluggable plug-in portions 521 arranged in the limit groove 33 are provided on both sides of the push plate 51. The middle bottom end of the push rod 52 is slidably connected to the middle of the base 1, and a positioning groove 522 for inserting the armature 53 is provided at one end of the push rod 52 away from the movable spring sheet 3, and the push rod 52 is swingably arranged in the positioning groove 522.

[0056] By providing two plug-in parts 521 on both sides of the front end of the push rod 52, as long as the plug-in parts 521 of the push rod 52 are inserted into the limiting groove 33, the push rod 52 and the movable spring piece 3 are positioned and matched, and the installation stability is good, so that the movable spring piece 3 is elastically offset toward the side close to the static spring piece 2 under the drive of the push rod 52, and when the movable spring piece 3 is disconnected from the static spring piece 2, the push rod 52 can be reset and moved under the elastic force of the movable spring piece 3. The assembly between the push rod 52 and the movable spring piece 3 is also relatively simple and convenient, which can be applied to automated assembly production and improve the installation efficiency. By providing a positioning groove 522 on the push rod 52, one end of the armature 53 is inserted into the positioning groove 522, so as to realize the transmission connection between the armature 53 and the push rod 52. With such a configuration, the installation connection is convenient and the matching transmission is reliable.

[0057] Furthermore, the magnetic circuit driving assembly 4 includes a driving coil 41 and a yoke 42 , and the armature 53 is swingably disposed at the top of the yoke 42 .

[0058] The magnetic circuit driving component 4 includes a driving coil 41 and a yoke 42. The armature 53 is swingably connected to the upper end of the yoke 42 and a compression spring 54 is provided between the yoke 42. When energized, the driving coil 41 generates an electromagnetic force to attract the armature 53, so that the armature 53 pushes the push rod 52 to move toward the side close to the static spring sheet 2 under the action of the electromagnetic force.

[0059] By arranging a reciprocating push rod 52 on the base 1, the base 1 and the bottom of the push rod 52 are slidably matched, and the plug-in portion 521 of the push rod 52 is connected to the middle portion of the movable spring 3. Then, when the armature 53 and the movable spring 3 are assembled, the armature 53 is connected to the push rod 52 through the inclined extending driving portion, so that the movable spring 3 and the push rod 52 form a linkage match, so that the push rod 52 with a reciprocating design is used to transmit motion and force between the armature 53 and the movable spring 3. When the driving coil 41 is energized to generate electromagnetic force, the armature 53 will be attracted to swing, so that the push rod 52 drives the movable spring 3 to contact the static spring 2 under the push of the armature 53, and when the driving coil 41 is de-energized, the push rod 52 will reset and move under the elastic force of the movable spring 3.

[0060] The relay has a more compact structure and a smaller volume, and has reliable transmission, thereby improving assembly efficiency and reducing production costs.

[0061] Among them, according to the installation groove extending along the length direction of the base 1, the push rod 52 can be reciprocated in the installation groove through the guide structure. The design of the installation groove and the guide structure plays an installation guide and movement guide role on the base 1, ensuring that the push rod 52 can reciprocate in the installation groove along the length direction of the base 1 to prevent the push rod 52 from positional displacement during the reciprocating movement, and can ensure reliable transmission and good installation stability.

[0062] When the two ends of the coil pins are energized, the coil's excitation current will generate magnetic flux, which will form a magnetic circuit through the iron core, the armature 53, the yoke 42 and the working air gap, and generate electromagnetic attraction in the working air gap; when the excitation current rises to reach the set value, the electromagnetic attraction torque will overcome the reaction torque of the movable spring 3, causing the armature 53 to swing on the yoke 42, generating a thrust force on the push plate 51 toward one side of the movable spring 3, and the push plate 51 pushes the spring 3 laterally, so that the moving contact 6 of the movable spring 3 and the static contact 7 of the static spring 2 are closed; when the excitation current decreases to the set value, the reaction torque of the movable spring 3 is greater than the electromagnetic attraction torque, generating a thrust force on the push plate 51 toward one side of the coil, and the push plate 51 pushes the armature 53 laterally, so that the armature 53 returns to the initial state, and the moving contact 6 of the movable spring 3 and the static contact 7 of the static spring 2 are disconnected.

[0063] In summary, the push rod relay provided by the present invention, by arranging a bent spring piece 31 on the moving spring piece 3, plays a role of buffering and slowing down the bounce during the release process of the relay, can reduce the bounce distance and bounce time after the contact is released, achieves the effect of quickly extinguishing the arc, and improves the service life of the relay.
