Abstract
Description
Technical Field
[0001] This utility model belongs to the field of relay technology, and in particular to a large-pitch relay with arc extinguishing function. Background Technology
[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the change in the input quantity (excitation quantity) reaches a specified requirement. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is commonly used in automated control circuits, and is essentially an "automatic switch" that uses a small current to control a large current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in circuits.
[0003] Currently, during the use of relays, the relay contacts are prone to generating electric arcs when they operate. These arcs have a thermal effect, which can easily lead to contact erosion and adhesion, thus shortening the relay's lifespan. Furthermore, the arcing process generates electromagnetic radiation, which may interfere with surrounding equipment and affect its normal operation. Utility Model Content

The first limiting flange and the second limiting flange are respectively provided on the corresponding two sides of the second mounting hole. The first mounting hole and the second mounting hole correspond to each other.

[0006] Furthermore, the housing also includes a limiting bracket disposed on the base and the top cover.
[0007] Further, the outer contour of the limiting frame is in a "C" shape.

[0010] Further, the bending section is provided at one end of the moving contact terminal body close to the first mounting hole.
[0011] Further, the extending direction of the second mounting hole is the same as the extending direction of the moving reed.
[0012] Further, the arc extinguishing unit includes an arc extinguishing unit provided between the moving contact assembly and the static contact assembly, and a plurality of through holes provided on the housing.
[0013] Further, the arc extinguishing unit is provided between the moving contact assembly and the static contact assembly.

[0015] Compared with the prior art, the large-pitch relay with arc-extinguishing function provided by this utility model drives the push-pull rod through the rotating armature assembly to drive the contact between the stationary contact assembly and the moving contact assembly, and the arc-extinguishing unit reduces the electric arc generated by the contact between the stationary contact assembly and the moving contact assembly.

The thickness of the movable spring is less than the width of the limiting groove to facilitate sliding within the limiting groove. The first limiting flange and the second limiting flange are respectively disposed on the corresponding two sides of the second mounting hole. When the push-pull rod slides along the second mounting hole, the first limiting flange and the second limiting flange in the push-pull rod limit the sliding range of the push-pull rod within the second mounting hole, preventing the push-pull rod from causing the movable spring to slide excessively. The arc-extinguishing unit includes an arc-extinguishing unit disposed between the movable contact assembly and the stationary contact assembly, and multiple through holes disposed on the housing. The through holes correspond to the arc-extinguishing unit, thereby guiding air between the movable contact assembly and the stationary contact assembly.

It can be seen that the large-pitch relay with arc-extinguishing function has a reasonable structure, reducing the impact of surge current on the relay contacts, thereby extending the relay's service life.

[0027] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.
[0028] like Figures 1 to 11 The diagram shows the structure of a large-pitch relay with arc-extinguishing function provided by this utility model. The large-pitch relay with arc-extinguishing function includes a housing 10, an electromagnetic component 20 disposed within the housing 10, a rotating armature component 30 disposed on one side of the electromagnetic component 20, a push-pull rod 40 driven to move by the rotating armature component 30, a stationary contact component 50 disposed within the housing 10, a moving contact component 60 disposed on one side of the stationary contact component 50, and an arc-extinguishing unit 70 disposed between the moving contact component 50 and the moving contact component 60. The large-pitch relay with arc-extinguishing function also includes other functional modules, such as assembly components, electrical connection components, etc., which are technologies known to those skilled in the art and will not be described in detail here.
[0029] The housing 10 includes a base 11, a top cover 12 disposed on the base 11, and a limiting frame 13 disposed on the base 11 and the top cover 12.
[0030] The base 11 and the top cover 12 are combined together, and a receiving cavity is formed between the base 11 and the top cover 12. The electromagnetic component 20, the rotating armature component 30, the push rod 40, the static contact component 50, the moving contact component 60, and the arc extinguishing unit 70 are all accommodated in this receiving cavity, so that an integral body is formed among the electromagnetic component 20, the rotating armature component 30, the push rod 40, the static contact component 50, the moving contact component 60, and the arc extinguishing unit 70. Both the base 11 and the top cover 12 are of the prior art and will not be elaborated here.
[0031] The outer contour of the limiting frame 13 is in a "C" shape. When the limiting frame 13 is installed on the base 11 and the top cover 12, both ends of the limiting frame 13 abut against the side walls of the base 11 and the top cover 12, thereby restricting the positions of the base 11 and the top cover 12, so as to facilitate the stable installation between the base 11 and the top cover 12. The limiting frame 13 is of the prior art and will not be elaborated here.
[0032] The electromagnetic component 20 includes an electromagnetic device 21 and two magnetic end heads 22 respectively disposed on the electromagnetic device 21. The electromagnetic component 20 is the core component of an electromagnetic relay. The electromagnetic component 20 is composed of an iron core and a coil. When the coil is powered on, the iron core is magnetized to generate a magnetic field, attracting the rotating armature component 30 to achieve the connection or disconnection of the circuit. The electromagnetic component 20 is of the prior art and will not be elaborated here.
[0033] The rotating armature component 30 includes a hinge seat 31 disposed on the base 11, an armature main body 32 rotatably connected to the hinge seat 31, two armature magnetic end heads 33 respectively disposed at both ends of the armature main body 32, and a driving rod 34 disposed on the armature main body 32.
[0034] The hinge seat 31 is used to install the armature main body 32 and restrict the position of the armature main body 32 on the base 11. The hinge seat 31 and the base 11 are fixedly connected together. The connection structure between the hinge seat 31 and the base 11 is of the prior art and will not be elaborated here.
[0035] The armature body 32 is hinged to the hinge seat 31. The hinge structure between the armature body 32 and the hinge seat 31 is a prior art and will not be described in detail here.
[0036] Two armature magnetic ends 33 are respectively disposed on both sides of the armature body 32, and the two armature magnetic ends 33 correspond to the two magnetic ends 22 respectively. In the electromagnetic component 20, through the alternating change of the magnetic poles of the two magnetic ends 22 on the electromagnetic component 20, one armature magnetic end 33 and the magnetic end 22 attract each other, and the other armature magnetic end 33 and the magnetic end 22 repel each other, thereby the electromagnetic component 20 drives the hinge seat 31 to rotate. The structure of the electromagnetic component 20 driving the rotating armature component 30 to rotate is a prior art, and will not be described in detail here.
[0037] The drive rod 34 includes a drive rod body 341 fixedly connected to the armature body 32, and a drive end 342 disposed on the drive rod body 341. The drive rod body 341 and the armature body 32 are integrally formed, thereby ensuring the structural stability between the drive rod 34 and the armature body 32.
[0038] The outer contour of the drive end 342 is cylindrical. The drive end 342 is used to connect the connecting end 43 together. Therefore, the drive end 342 will be described in detail in conjunction with the push-pull rod 40.
[0039] The push-pull rod 40 includes a push-pull rod body 41, a push-pull end 42 disposed at one end of the push-pull rod body 41, and a connecting end 43 disposed at the end of the push-pull rod body 41 opposite to the push-pull end 42.
[0040] The push-pull rod body 41 is a prior art and will not be described in detail here. The push-pull rod body 41, the push-pull end 42, and the connecting end 43 are integrally formed to ensure the stability of the push-pull rod 40 structure.
[0041] The push-pull end 42 includes a push-pull end body 421 disposed on the push-pull rod body 41, and two limiting grooves 422 symmetrically disposed on both sides of the push-pull end body 421. The thickness of the movable spring 62 is less than the width of the limiting groove 422, so as to facilitate the sliding of the movable spring 62 within the limiting groove 422.
[0042] The connecting end 43 includes a connecting end body 431 and two symmetrically arranged receiving grooves 432 on the connecting end body 431. In this embodiment, the outer contour of the receiving groove 432 is cylindrical, and the outer contour of the driving end 342 is also cylindrical, so that the driving end 342 can be accommodated in the receiving groove 432 to achieve mutual connection, and the driving end 342 and the connecting end 43 are rotatable, so that the driving rod 34 can drive the push-pull rod 40 to extend and retract, thereby driving the following moving spring 62 to extend and retract.
[0043] The stationary contact assembly 50 includes a stationary contact terminal 51 disposed on the base 11, at least two stationary contacts 52 disposed on the side of the stationary contact terminal 51 facing the moving contact assembly 60, and a stationary contact external wiring terminal 53 disposed at one end of the stationary contact terminal 51.
[0044] One end of the stationary contact terminal 51 is fixedly connected to the base 11, and the other end of the stationary contact terminal 51 is provided with the stationary contact external wiring terminal 53. The stationary contact terminal 51 is a prior art and will not be described in detail here.
[0045] There are at least two stationary contacts 52, which are used to cooperate with the moving contact assembly 60. Therefore, the stationary contacts 52 will be combined with the moving contact assembly 60.
[0046] The external terminal 53 of the stationary contact is used to connect to external wiring. The external terminal 53 of the stationary contact is a prior art and will not be described in detail here.
[0047] The moving contact assembly 60 includes a moving contact terminal 61 disposed on the base 11, a moving spring 62 disposed on the moving contact terminal 61, a first mounting hole 63 disposed on the moving contact terminal 61, a second mounting hole 64 disposed on the moving spring 62, a first limiting flange 65 disposed on the side of the moving spring 62 facing the stationary contact assembly 50, and a second limiting flange 66 disposed on the side of the moving spring 62 facing the moving contact terminal 61.
[0048] The moving contact terminal 61 includes a moving contact terminal body 611, a bent section 612 disposed at one end of the moving contact terminal body 611, and a moving contact external wiring terminal 613 disposed at one end of the bent section 612.
[0049] The end of the moving contact terminal body 611 away from the moving contact external wiring terminal 613 is fixedly connected to the base 11, thereby fixing the moving contact assembly 60 into the base 11.
[0050] The bent section 612 is disposed at one end of the moving contact terminal body 611 near the first mounting hole 63, thereby forming a movable space for the moving contact terminal 61 at the position of the first mounting hole 63, so as to facilitate the movement of the push-pull rod 40.
[0051] The moving contact external wiring terminal 613 is used to connect to external wiring. The moving contact external wiring terminal 613 is a prior art and will not be described in detail here.
[0052] The moving spring 62 includes a moving spring body 621 disposed on the moving contact terminal 61, and at least two moving contacts 622 disposed on the side of the moving contact body 621 facing the stationary contact assembly 50.
[0053] One end of the movable spring body 621 is fixedly connected to the movable contact terminal 61. The movable spring body 621 is a prior art and will not be described in detail here.
[0054] The moving contact 622 is disposed at one end of the moving reed body 621 near the arc-extinguishing unit 70, so that the arc-extinguishing unit 70 can eliminate the electric arc between the moving contact 622 and the stationary contact 52. In this embodiment, there are two stationary contacts 52 and two moving contacts 622 to improve the current-carrying capacity of the stationary contact terminal 51 and the moving reed 62.
[0055] The first mounting hole 63 and the second mounting hole 64 correspond to each other so that the push-pull rod 40 passes through the moving contact terminal 61 and the moving spring 62, and the push-pull rod 40 and the moving spring 62 are connected to each other.
[0056] The second mounting hole 64 is provided on the moving spring body 621, and the second mounting hole 64 is located on the side of the moving contact 622 away from the arc extinguishing unit 70, so as to prevent the drive rod 34 from interfering with the arc extinguishing unit 70 during the sliding process along the second mounting hole 64. In addition, the extension direction of the second mounting hole 64 is consistent with the extension direction of the moving spring 62. When the push-pull end 42 in the push-pull rod 40 is installed in the second mounting hole 64, the push-pull end 42 is first aligned with the second mounting hole 64 so that the push-pull end 42 passes through the second mounting hole 64. Then, the push-pull end 42 is rotated 90 degrees so that the moving spring 62 is accommodated in the limiting groove 422 in the push-pull end 42, thereby realizing the connection between the moving spring 62 and the push-pull end 42.
[0057] The first limiting flange 65 and the second limiting flange 66 are respectively disposed on the corresponding two sides of the second mounting hole 64. When the push-pull rod 40 slides along the second mounting hole 64, the first limiting flange 65 and the second limiting flange 66 in the push-pull rod 40 are used to limit the sliding range of the push-pull rod 40 in the second mounting hole 64, and prevent the push-pull rod 40 from causing the moving spring 62 to slide excessively.
[0058] The arc extinguishing unit 70 includes an arc extinguishing unit 71 disposed between the moving contact assembly 60 and the stationary contact assembly 50, and a plurality of through holes 72 disposed on the housing 10.
[0059] The arc-extinguishing unit 71 is disposed between the moving contact assembly 60 and the stationary contact assembly 50. The arc-extinguishing unit 71 is a device specifically designed to control and extinguish electric arcs generated in electrical equipment. An electric arc is a discharge phenomenon that occurs when current is interrupted in electrical equipment or systems. It is characterized by high temperature, high energy, and strong electromagnetic radiation, and can easily cause dangers such as fires, explosions, and equipment damage. The arc-extinguishing unit 71 is existing technology and will not be described in detail here.
[0060] The through hole 72 corresponds to the arc extinguishing unit 71, so that the through hole 72 guides air to the space between the moving contact assembly 60 and the stationary contact assembly 50, so that the electric arc generated between the moving contact assembly 60 and the stationary contact assembly 50 is placed in the high-speed flowing air, causing the arc temperature to drop rapidly, thereby extinguishing the arc.
[0061] Compared with the prior art, the large-pitch relay with arc extinguishing function provided by this utility model drives the push-pull rod 40 through the rotating armature assembly 30 to drive the stationary contact assembly 50 and the moving contact assembly 60 to make contact, and the arc extinguishing unit 70 reduces the electric arc generated by the contact between the stationary contact assembly 50 and the moving contact assembly 60. The push-pull rod 40 has a connecting end 43 on one end of its body 41 facing away from the push-pull end 42. The connecting end 43 is connected to the drive rod 34 in the rotating armature assembly 30, enabling the rotating armature assembly 30 to drive the extension and retraction of the push-pull rod 40. The moving contact assembly 60 includes a moving contact terminal 61 on the base 11, a moving spring 62 on the moving contact terminal 61, a first mounting hole 63 on the moving contact terminal 61, a second mounting hole 64 on the moving spring 62, a first limiting flange 65 on the side of the moving spring 62 facing the stationary contact assembly 50, and a second limiting flange 66 on the side of the moving spring 62 facing the moving contact terminal 61. The push-pull end body 421 of the push-pull end 42 has limiting grooves 422 on both sides. The thickness of the movable spring 62 is less than the width of the limiting groove 422, so that the movable spring 62 can slide within the limiting groove 422. The first limiting flange 65 and the second limiting flange 66 are respectively disposed on the corresponding two sides of the second mounting hole 64. When the push-pull rod 40 slides along the second mounting hole 64, the first limiting flange 65 and the second limiting flange 66 in the push-pull rod 40 are used to limit the sliding range of the push-pull rod 40 in the second mounting hole 64, preventing the push-pull rod 40 from causing the movable spring 62 to slide excessively. The arc extinguishing unit 70 includes an arc extinguishing unit 71 disposed between the movable contact assembly 60 and the stationary contact assembly 50, and a plurality of through holes 72 disposed on the housing 10. The through-hole 72 corresponds to the arc-extinguishing unit 71, thereby guiding air between the moving contact assembly 60 and the stationary contact assembly 50. This places the electric arc generated between the moving contact assembly 60 and the stationary contact assembly 50 in the high-speed flowing air, rapidly reducing the arc temperature and extinguishing the arc. It can be seen that the large-pitch relay with arc-extinguishing function has a reasonable structure, reducing the impact of surge current on the relay contacts and thus extending the relay's service life.
[0062] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model.
