Description

Technical Field

[0001] The utility model relates to the technical field of relays, and more specifically, to an auxiliary contact system for a relay contact. Background Art

[0002] A relay, also known as an electromagnetic relay, is an electronic control device that has a control system and a controlled system. It is usually applied to an automatic control circuit. It is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays roles such as automatic regulation, safety protection, and circuit conversion in the circuit. When using a relay, an auxiliary contact system for a relay contact needs to be proposed.

[0003] Currently, most of the moving reed and the static reed inside the relay are fixed to the base by welding. Although this method can effectively fix the moving reed and the static reed on the base, the installation process is time-consuming and laborious, thus reducing the installation efficiency of the moving reed and the static reed. Moreover, when one of the moving reed or the static reed is damaged, the entire relay needs to be replaced, and it is not possible to effectively replace a single component of the moving reed or the static reed. This will result in a significant increase in the maintenance cost for users. In addition, the current contact structures of relays are relatively complex and have low practicability. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an auxiliary contact system for a relay contact, which includes a base, and further includes:

[0005] A moving reed and a static reed, both located above the base. Installation holes for installing contacts are respectively formed through the interiors of the moving reed and the static reed. First installation grooves for installing the moving reed and second installation grooves for installing the static reed are respectively formed on the upper surface of the base;

[0006] A magnet, arranged inside the base;

[0007] A fixing block, fixedly connected to the upper surface of the magnet. An activity groove for the moving reed to move is formed on the upper surface of the fixing block.

[0008] As a further improvement of this technical solution, a convex block is fixedly connected to the outside of the moving reed, and a clamping groove for clamping the convex block is formed on the inner wall of the first installation groove.

[0009] As a further improvement of this technical solution, two elastic pieces are fixedly connected to the inside of the static reed, and a clamping groove for clamping the elastic pieces is formed on the inner wall of the second installation groove.

[0010] As a further improvement of this technical solution, a limiting plate is fixedly connected to the outside of the moving reed.

[0011] As a further improvement of the technical solution, the materials of the moving reed and the static reed are both manganese steel.

[0012] As a further improvement of the technical solution, the material of the limiting plate is rubber.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] In the auxiliary contact system of a relay contact, through the arranged moving reed, static reed, first installation groove, second installation groove, magnet and fixing block, when it is necessary to install the moving reed and the static reed on the base, only need to insert the moving reed into the first installation groove and insert the static reed into the second installation groove. At this time, the installation process of the moving reed and the static reed can be conveniently carried out, without the need to use welding or other methods for fixation, which is relatively convenient. At the same time, it is convenient for the user to disassemble and replace a single damaged part, reducing the maintenance cost of the user. During the rotation of the magnet, the fixing block will be driven to rotate synchronously. At this time, the fixing block will drive the moving reed to move synchronously, and the moving reed will drive the contact to move synchronously. When the contact inside the moving reed contacts the contact inside the static reed, the switching function of the auxiliary contact can be realized, saving time and effort.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 - Figure 4 As shown in the figure, this embodiment provides an auxiliary contact system for a relay contact, including a base 1, and further including:

[0023] A moving reed 4 and a static reed 5, both located above the base 1. Installation holes for installing the contact 6 are respectively provided through the interiors of the moving reed 4 and the static reed 5. A first installation groove 8 for installing the moving reed 4 and a second installation groove 9 for installing the static reed 5 are respectively provided on the upper surface of the base 1;

[0024] A magnet 2, arranged inside the base 1;

[0025] A fixing block 3, fixedly connected to the upper surface of the magnet 2. An activity groove for the moving reed 4 to move is provided on the upper surface of the fixing block 3.

[0026] The above working principle: When it is necessary to install the moving reed 4 and the static reed 5 on the base 1, only need to insert the moving reed 4 into the first installation groove 8 and insert the static reed 5 into the second installation groove 9. At this time, the moving reed 4 and the static reed 5 can be conveniently installed without using methods such as welding for fixation, which is more convenient. At the same time, it is convenient for the user to disassemble and replace a single damaged part, reducing the user's maintenance cost. During the rotation of the magnet 2, the fixing block 3 will be driven to rotate synchronously. At this time, the fixing block 3 will drive the moving reed 4 to move synchronously, and the moving reed 4 will drive the contact 6 to move synchronously. When the contact 6 inside the moving reed 4 contacts the contact 6 inside the static reed 5, the switching function of the auxiliary contact can be realized, saving time and effort.

[0027] In order to effectively fix and install the moving reed 4 and the base 1, a convex block 10 is fixedly connected to the outside of the moving reed 4. A clamping groove for clamping the convex block 10 is provided on the inner wall of the first installation groove 8. When it is necessary to fix and install the moving reed 4 and the base 1, only need to insert the moving reed 4 into the inside of the first installation groove 8. At this time, the moving reed 4 will drive the convex block 10 to move synchronously. When the convex block 10 is clamped into the clamping groove provided on the inner wall of the first installation groove 8, the moving reed 4 can be fixedly installed inside the base 1.

[0028] Considering that when using the relay, the static reed 5 also needs to be fixedly installed inside the base 1, two elastic pieces 11 are fixedly connected inside the static reed 5, and a clamping groove for clamping the elastic piece 11 is formed on the inner wall of the second installation groove 9. When it is necessary to fixedly install the static reed 5, only need to insert the static reed 5 into the second installation groove 9 first. At this time, the static reed 5 will drive the elastic piece 11 to move synchronously. When the elastic piece 11 enters the second installation groove 9, it will be squeezed. When the static reed 5 drives the elastic piece 11 to move into the clamping groove formed on the inner wall of the second installation groove 9, the elastic piece 11 resets. When the elastic piece 11 is clamped into the clamping groove formed on the inner wall of the second installation groove 9, the static reed 5 can be fixedly installed.

[0029] In order to prevent the moving reed 4 from disengaging from the movable groove on the upper surface of the fixed block 3 when the magnet 2 drives the fixed block 3 to rotate, a limiting plate 7 is fixedly connected to the outside of the moving reed 4. Through the setting of the limiting plate 7, the moving reed 4 can be effectively limited, thereby preventing the moving reed 4 from disengaging from the movable groove on the upper surface of the fixed block 3 and affecting the auxiliary contact effect of the relay.

[0030] In order to effectively extend the service life of the moving reed 4 and the static reed 5, the materials of the moving reed 4 and the static reed 5 are both manganese steel. Manganese steel is a high-strength and high-toughness alloy steel, and its main alloying element is manganese. The strength of manganese steel is higher than that of ordinary steel, and it also has good impact resistance and wear resistance. Since the materials of the moving reed 4 and the static reed 5 are both manganese steel, the service life of the moving reed 4 and the static reed 5 can be greatly improved, and the moving reed 4 and the static reed 5 can have good elasticity, so as to effectively improve the auxiliary contact effect of the relay.

[0031] In addition, in order to prevent the limiting plate 7 from damaging the fixed block 3 or the moving reed 4, the material of the limiting plate 7 is rubber. Since the material of the limiting plate 7 is rubber, even if the limiting plate 7 collides with the fixed block 3, it will not damage the fixed block 3, and at the same time, it can play a certain protective role for the moving reed 4.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention, and are not used to limit the present invention.
