Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to a contact system structure and a relay. Background Art

[0002] An electromagnetic relay is an electronic control device with a control system (also known as an input circuit) and a controlled system (also known as an output circuit). It is usually used in automatic control circuits. It is actually an "automatic switch" that uses a smaller current and a lower voltage to control a larger current and a higher voltage.

[0003] Relays can be categorized by their connection type: normally open, normally closed, and changeover. Normally open relays are open when no signal is output and closed when a signal is received; normally closed relays are closed when no signal is output and open when a signal is received; changeover relays can be switched to normally open or normally closed as needed. Relays of different switching types differ in structure and switching methods, making it difficult to switch between different connection types and making switching operations more challenging.

[0004] Therefore, there is an urgent need to provide a contact system structure and a relay to meet the switching requirements of different connection types and reduce the difficulty of switching operations. Utility Model Content

[0045] like Figures 1 to 6 As shown, this embodiment provides a contact system structure and a relay. The relay includes an electromagnetic assembly 30 and a contact system structure. The electromagnetic assembly 30 is used to drive the armature 11 of the contact system structure to move relative to the base 20. The contact system structure includes the base 20, the armature 11, and a movable spring assembly. The base 20 is provided with a normally open contact 21 and a normally closed contact 22. The armature 11 is movably mounted on the base 20 for connecting to the electromagnetic assembly 30 of the relay. The armature 11 is provided with an armature shaft 111. There is at least one movable spring assembly, each of which includes a movable spring that is detachably mounted on the armature shaft 111. The armature shaft 111 is provided with at least two mounting locations for mounting one or two movable spring assemblies. Each movable spring is provided with a movable contact. The armature 11 can move relative to the base 20 to drive the movable spring to move, causing the movable contact to contact or separate with the normally open contact 21 or the normally closed contact 22.

[0046] By detachably sleeved with one or two movable spring assemblies on the mounting position of the armature shaft 111, and utilizing the movable contact on the movable spring to contact or separate with the corresponding normally open contact 21 or normally closed contact 22, switching between different connection modes is achieved; when only one movable spring assembly is provided, if the movable spring assembly is in contact with the normally closed contact 22 when no signal is output, the normally closed state is maintained (i.e., normally closed type); if the movable spring assembly is separated from the normally open contact 21 when no signal is output, the normally open state is maintained (i.e., normally open type); when two movable spring assemblies are provided (i.e., switching type), the armature 11 is utilized to drive the two movable spring assemblies to move, thereby achieving switching between the normally open and normally closed states; the component structures of relays with different connection modes are simplified and unified, the versatility of the components is improved, and the operational difficulty of switching between different connection modes is effectively reduced.

[0047] By providing a relay with an electromagnetic assembly 30, the electromagnetic assembly 30 is used to drive the armature 11 to move relative to the base 20, thereby changing the angle of the armature 11, thereby driving the movable spring to move, making it easy to switch between different connection modes and having strong applicability.

[0048] Specifically, the base 20 is provided with a stationary contact assembly comprising two normally closed contacts 22 and two normally open contacts 21, with the normally closed contacts 22 and the normally open contacts 21 facing each other in a vertical direction. Each normally closed contact 22 is located above the normally open contacts 21. Each movable spring has a movable contact at each end. By providing two movable contacts on the movable spring, corresponding to the two normally closed contacts 22 or the two normally open contacts 21, even if one contact fails, conduction can still be achieved, ensuring stable relay performance. In other embodiments, the number of contacts can be single or multiple, depending on the actual situation.

[0049] In this embodiment, the relay further includes a housing 50 , which is covered on the base 20 ; the housing 50 and the base 20 are snap-fitted together.

[0050] Furthermore, the relay includes a second elastic member 40, through which the armature 11 is connected to the electromagnetic assembly 30. When the electromagnetic assembly 30 is powered on or off, it drives the armature 11 to move, causing the movable contact to contact or separate from the static contact, thereby connecting or disconnecting the circuit. By providing the second elastic member 40, when the electromagnetic assembly 30 is powered off, the armature 11 is automatically reset by the action of the second elastic member 40.

[0051] In this embodiment, the electromagnetic assembly 30 is mounted on the base 20 and includes a second core 32. A hook 112 is provided on the armature 11, and hooks are also provided at the ends of the second core 32. The ends of the second elastic member 40 are respectively hooked on the hooks 112 and the second core 32. The second elastic member 40 may be a tension spring; the provision of hooks on the armature 11 and the second core 32 facilitates installation and maintenance of the second elastic member 40.

[0052] In this embodiment, the electromagnetic assembly 30 further includes a first iron core 31. Grooves 113 are provided on either side of the armature 11. Each of the first iron cores 31 is provided with support arms 311 corresponding one-to-one to the grooves 113. The support arms 311 are at least partially inserted into the grooves 113, and the ends of the support arms 311 are slidably inserted into the base 20. By providing the grooves 113 on the armature 11 and inserting the support arms 311 of the first iron core 31 into the grooves 113, the first iron core 31 can restrict the left and right position of the armature 11, preventing the armature 11 from moving left or right. The ends of the support arms 311 are slidably inserted into the base 20, thereby enabling the first iron core 31 and the armature 11 to be mounted on the base 20.

[0053] In this embodiment, the first iron core 31 has a U-shaped notch, and the two support arms 311 are respectively located on both sides of the U-shaped notch. The inner sides of the two support arms 311 facing each other are respectively provided with protrusions 3111, and the support arms 311 are slidably inserted into the base 20 through the protrusions 3111; the U-shaped notch of the first iron core 31 also has a limiting surface 312, and the limiting surface 312 is attached to the armature 11, thereby limiting the upper and lower positions of the armature 11, so that the angle between the position of the armature 11 and the base 20 can be maintained within a certain range.

[0054] During the use of the relay, under the action of the second elastic member 40, the armature 11 can maintain its upward extension, the armature 11 is in contact with the limit surface 312, and the normally closed contact 22 is connected; after the current is connected to the electromagnetic component 30, the coil of the electromagnetic component 30 generates a magnetic field, thereby generating an attraction on the armature 11, so that the angle between the armature 11 and the base 20 gradually decreases, and the normally open contact 21 is connected.

[0055] Optionally, one end of the armature 11 is integrally bent to form an armature shaft 111, with a shorting ring 114 provided at the other end. The shorting ring 114 utilizes the principle of magnetic induction to eliminate armature vibration. In this embodiment, the hook 112 is located between the armature shaft 111 and the groove 113. The integral bending method of the armature shaft 111 provides a simple structure, high operational sensitivity, and stability, helping to ensure the overall performance and reliability of the relay, effectively saving processing steps and time, and improving production efficiency.

[0056] See also Figure 2One end of the armature 11 is rotatably connected to the base 20. The other end of the armature 11 is provided with an armature shaft 111. A buffer 16 is embedded in the armature 11. An adjusting member 17 is threadedly connected to the base 20. The end of the adjusting member 17 passes through the base 20 and abuts against the buffer 16. The adjusting member 17 allows the initial position of the armature 11 relative to the base 20 to be adjusted. The buffer 16, with its end abutting against the adjusting member 17, reduces the impact force between the armature 11 and the adjusting member 17. The adjusting member 17 can be an adjustment screw. The buffer 16 is elastic and made of an insulating material (such as rubber), serving multiple purposes, eliminating the need for separate elastic and insulating components.

[0057] Furthermore, the contact system structure includes a first elastic member 14, which is sleeved on the armature shaft 111 and has its end abutting the movable spring. By providing the first elastic member 14 on the armature shaft 111, the first elastic member 14 can provide elastic force to the movable spring, ensuring that the movable contact on the movable spring can connect with the static contact on the base 20, avoiding connection failure due to positional deviation or gap.

[0058] See also Figure 1 and Figure 6 The two movable spring assemblies are a first movable spring assembly 12 and a second movable spring assembly 13, with the second movable spring assembly 13 located above the first movable spring assembly 12. When both the first movable spring assembly 12 and the second movable spring assembly 13 are sleeved on the armature shaft 111, the first elastic member 14 is located between the first movable spring assembly 12 and the second movable spring assembly 13, with both ends of the first elastic member 14 abutting against the movable springs of the first and second movable spring assemblies 12 and 13, respectively (i.e., the first and second movable spring assemblies 12 and 13 are respectively installed at two installation positions on the armature shaft 111). When the electromagnetic assembly 30 is de-energized, the armature 11 moves upward and resets under the action of the second elastic member 40, causing the second movable spring assembly 13 to contact the normally closed contact 22, and the first elastic member 14 then pulls the first movable spring assembly 12 away from the normally open contact 21. The first elastic member 14 may be a spring.

[0059] Furthermore, the contact system structure includes a clamp 15. A clamping slot is provided at each mounting position of the armature shaft 111. The clamp 15 is sleeved on the armature shaft 111 and partially retained within the clamping slot, thereby restraining the first elastic member 14 and the movable spring and maintaining the first elastic member 14 in a compressed state. The clamp 15 cooperates with the clamping slot to restrain the first elastic member 14 and the movable spring, maintaining the first elastic member 14 in a compressed state and providing elastic force to the movable spring.

[0060] See also Figure 7 and Figure 8When only one movable spring assembly is sleeved on the armature shaft 111 , the contact system structure further includes a gasket 18 , which is disposed between the clamp 15 and the first elastic member 14 , or between the first elastic member 14 and the armature 11 .

[0061] In this embodiment, the armature shaft 111 is provided with two installation positions, and the two clamping grooves at the two installation positions are spaced apart along the axis direction of the armature shaft 111. Figure 5 There are two card slots, namely the first card slot 1111 and the second card slot 1112; see Figure 7 The first movable spring assembly 12, the first elastic member 14 and the gasket 18 are sequentially sleeved on the armature shaft 111, and the clamp 15 is partially clamped in the first clamping groove 1111; Figure 8 The gasket 18 , the first elastic member 14 and the second movable spring assembly 13 are sequentially sleeved on the armature shaft 111 , and at this time, the clamp 15 is partially clamped in the second clamping groove 1112 .

[0062] See also Figure 9 The first movable spring assembly 12 includes a first movable spring 121 and a first movable contact 122 disposed on the first movable spring 121. The two first movable contacts 122 are disposed at either end of the first movable spring 121. A through-hole is defined in the center of the first movable spring 121 for insertion of the armature shaft 111. A flange 123 is provided around the through-hole, and the first elastic member 14 is sleeved over the flange 123. The through-hole and flange 123, coupled with the armature shaft 111 and the square cross-section of the through-hole and armature shaft 111, effectively restrict the armature shaft 111 from rotating about its axis.

[0063] See also Figure 10 The second movable spring assembly 13 includes a second movable spring 131 and a second movable contact 132 provided on the second movable spring 131; the two second movable contacts 132 are respectively provided at both ends of the second movable spring 131, and a through hole is provided in the middle of the second movable spring 131 for the armature shaft 111 to be inserted; the second movable spring assembly 13 also includes an insulating member 133, and the insulating member 133 is partially located between the armature shaft 111 and the hole wall of the through hole on the second movable spring 131.

[0064] In this embodiment, the cross section of the armature shaft 111 is square, and the through holes on the first movable spring piece 121 and the second movable spring piece 131 are both square. In other embodiments, the cross section of the armature shaft 111 can also be set to other triangular or polygonal shapes.

[0065] By providing an insulating member 133 in the second movable spring assembly 13, the insulating member 133 isolates the armature shaft 111 from the through-hole in the second movable spring 131, thereby providing insulation. The insulating member 133 can be made of insulating plastic. In this embodiment, the first movable spring 121 of the first movable spring assembly 12 can be connected to the armature shaft 111. In other embodiments, the insulating member 133 can be provided at the through-holes of both the first and second movable springs 121, 131, or only at the through-hole of the first movable spring 121. This ensures that the first and second movable springs 121, 131 are not simultaneously connected to the armature shaft 111, thereby preventing a short circuit caused by simultaneous connection between the first and second movable springs 121, 131.

[0066] The following is the specific combination and use process of the contact system structure:

[0067] See also Figure 6 When the relay is to adopt a conversion-type connection mode, the first movable spring assembly 12, the first elastic member 14 and the second movable spring assembly 13 are installed on the armature shaft 111. The first elastic member 14 and the second movable spring assembly 13 are stacked in sequence above the first movable spring assembly 12, and the clamp 15 is partially clamped in the second clamping groove 1112.

[0068] See also Figure 7 When the relay is to adopt the normally open connection mode, the first movable spring assembly 12, the first elastic member 14 and the gasket 18 are installed on the armature shaft 111, and the clamp 15 is partially clamped in the first clamping groove 1111. Under the action of the first elastic member 14, the first movable spring 121 of the first movable spring assembly 12 is pressed against the armature 11.

[0069] See also Figure 8 When the relay is to adopt the normally closed connection type, the gasket 18, the first elastic member 14 and the second movable spring assembly 13 are installed on the armature shaft 111. The gasket 18 is attached to the armature 11 and is located between the first elastic member 14 and the armature 11. The clamp 15 is partially clamped in the second clamping groove 1112.

[0070] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
