Description

Technical Field

[0001] The utility model relates to the technical field of relays, and specifically, to a two-way output relay. 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 flame detector, a two-way output relay is required.

[0003] Traditional flame detection is mainly based on sensors such as temperature, infrared, and smoke. In recent years, solutions based on video monitoring have been proposed, but these methods are too simple and immature to be put into practical applications. Color features are an important basis for judging flames, but there are many problems. First, the color model is simple, mostly generated by manual statistics, and cannot cover all situations. Second, simply judging each pixel based on these color features without combining the target motion information in the scene, so relying solely on it is unreliable. In a traditional relay, generally only one armature is used for circuit output. However, when the relay is damaged, the reed and the fixed terminal cannot be disconnected, which will cause the relay to fail to function properly, resulting in circuit damage and affecting the normal use of the flame detector.

[0004] Therefore, those skilled in the art have provided a two-way output relay to solve the problems raised in the above background art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a two-way output relay, including a base, and further including:

[0006] A mounting seat, arranged inside the base;

[0007] A skeleton, arranged on the upper surface of the mounting seat, and a coil is sleeved outside the skeleton;

[0008] A first armature and a second armature, both located above the base;

[0009] A first push piece and a second push piece, both located above the base. Clamping grooves for clamping the first armature and the second armature are respectively formed inside the first push piece and the second push piece;

[0010] A first fixing plate and a second fixing plate, both located above the base. Clamping grooves for clamping the first fixing plate and the second fixing plate are respectively formed on the upper surface of the base. Static contacts are arranged inside both the first fixing plate and the second fixing plate;

[0011] The first reed and the second reed are both located above the base. The upper surface of the base is respectively provided with clamping grooves for clamping the first reed and the second reed. The interiors of the first reed and the second reed are both provided with moving contacts, and the interiors of the first reed and the second reed are respectively provided with clamping grooves for clamping the first push piece and the second push piece.

[0012] As a further improvement of this technical solution, a clamping groove for clamping the mounting seat is provided inside the base.

[0013] As a further improvement of this technical solution, a through hole for the movement of the T-shaped plate is penetrated inside the skeleton, a clamping groove for clamping the T-shaped plate is provided inside the mounting seat, and the skeleton and the mounting seat are fixedly connected through the T-shaped plate.

[0014] As a further improvement of this technical solution, lead pins are symmetrically provided inside the skeleton.

[0015] As a further improvement of this technical solution, connecting pieces are symmetrically provided between the base and the mounting seat, and the outer parts of the two connecting pieces are respectively fixedly connected to the outer parts of the first armature and the second armature.

[0016] As a further improvement of this technical solution, elastic pieces are provided inside the two connecting pieces.

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

[0018] In this two-way output relay, through the arranged first armature, second armature, first push piece, second push piece, static contact and moving contact, when the relay is powered on, the coil will start to operate. At this time, the first armature and the second armature will move synchronously. The first armature and the second armature will respectively drive the first push piece and the second push piece to move synchronously. The first push piece and the second push piece will respectively drive the first reed and the second reed to move synchronously. The first reed and the second reed will drive the moving contact to move synchronously. At this time, the moving contact can be closed with the static contact through the first reed and the second reed. When the relay is powered off, the first reed and the second reed will drive the moving contact to disconnect from the static contact, thereby realizing the on-off function of the relay in the circuit. When there is a situation where the moving contact inside the first reed cannot disconnect from the static contact in the relay, the moving contact inside the second reed can still be normally disconnected from the static contact. Or when the moving contact inside the second reed cannot disconnect from the static contact, the moving contact inside the first reed can still be normally disconnected from the static contact. Thus, the circuit can be effectively protected, preventing the relay from using only one armature for circuit output and resulting in a situation where the moving contact cannot be separated from the static contact, which affects the normal use effect of the relay.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figure 1 - Figure 6 as shown, this embodiment provides a two-way output relay, including a base 1, and further including:

[0029] A mounting seat 6, which is arranged inside the base 1;

[0030] A skeleton 7, which is arranged on the upper surface of the mounting seat 6, and a coil 11 is sleeved outside the skeleton 7;

[0031] A first armature 4 and a second armature 5, both located above the base 1;

[0032] The first pusher 2 and the second pusher 3 are both located above the base 1. The interiors of the first pusher 2 and the second pusher 3 are respectively provided with clamping grooves for clamping the first armature 4 and the second armature 5.

[0033] The first fixing plate 12 and the second fixing plate 13 are both located above the base 1. The upper surface of the base 1 is respectively provided with clamping grooves for clamping the first fixing plate 12 and the second fixing plate 13. The interiors of the first fixing plate 12 and the second fixing plate 13 are both provided with static contacts 14.

[0034] The first reed 15 and the second reed 16 are both located above the base 1. The upper surface of the base 1 is respectively provided with clamping grooves for clamping the first reed 15 and the second reed 16. The interiors of the first reed 15 and the second reed 16 are both provided with moving contacts 17. The interiors of the first reed 15 and the second reed 16 are respectively provided with clamping grooves for clamping the first pusher 2 and the second pusher 3.

[0035] The above working principle: When the relay is powered on, the coil 11 will start to operate. At this time, the first armature 4 and the second armature 5 will move synchronously. The first armature 4 and the second armature 5 will then respectively drive the first pusher 2 and the second pusher 3 to move synchronously. The first pusher 2 and the second pusher 3 will then respectively drive the first reed 15 and the second reed 16 to move synchronously. The first reed 15 and the second reed 16 will then drive the moving contacts 17 to move synchronously. At this time, the moving contacts 17 can be closed with the static contacts 14 through the first reed 15 and the second reed 16. When the relay is powered off, the first reed 15 and the second reed 16 will drive the moving contacts 17 to disconnect from the static contacts 14, thereby realizing the on-off function of the relay in the circuit. When there is a situation where the moving contact 17 inside the first reed 15 cannot disconnect from the static contact 14 in the relay, the moving contact 17 inside the second reed 16 can still disconnect normally from the static contact 14. Or when the moving contact 17 inside the second reed 16 cannot disconnect from the static contact 14, the moving contact 17 inside the first reed 15 can still disconnect normally from the static contact 14. Thus, the circuit can be effectively protected, preventing the relay from using only one armature for circuit output and resulting in a situation where the moving contact 17 cannot separate from the static contact 14, which affects the normal use effect of the relay.

[0036] In order to conveniently fix and install the mounting seat 6 inside the base 1, a clamping groove for clamping the mounting seat 6 is provided inside the base 1. When it is necessary to fix and install the mounting seat 6 inside the base 1, only need to insert the mounting seat 6 into the clamping groove inside the base 1. At this time, the mounting seat 6 can be installed, thereby facilitating the staff to assemble other components, and further facilitating the staff to assemble the relay as a whole.

[0037] Considering that when assembling the relay, the coil 11 also needs to be fixedly installed inside the base 1, a through hole 8 for the movement of the T-shaped plate 10 is provided through the inside of the skeleton 7, and a clamping groove for clamping the T-shaped plate 10 is provided inside the mounting seat 6. The skeleton 7 and the mounting seat 6 are fixedly connected through the T-shaped plate 10. When the coil 11 needs to be fixedly installed inside the base 1, only need to first place the skeleton 7 on the mounting seat 6, then pass the T-shaped plate 10 through the through hole 8 inside the skeleton 7, and then insert the T-shaped plate 10 into the clamping groove inside the mounting seat 6. At this time, the skeleton 7 and the mounting seat 6 can be fixedly assembled through the T-shaped plate 10, so that the coil 11 and the mounting seat 6 can be installed. After the coil 11 is installed, then assemble the mounting seat 6 and the base 1. At this time, the coil 11 can be fixedly installed inside the base 1.

[0038] In order to effectively energize the relay, lead pins 9 are symmetrically provided inside the skeleton 7. When the relay needs to be energized, only need to energize the lead pins 9. At this time, the coil 11 can start to operate, so that the first armature 4 and the second armature 5 can move. When the lead pins 9 are de-energized, the relay will also be de-energized synchronously.

[0039] In order to conveniently install the first armature 4 and the second armature 5, connecting pieces 19 are symmetrically provided between the base 1 and the mounting seat 6. The outer parts of the two connecting pieces 19 are respectively fixedly connected to the outer parts of the first armature 4 and the second armature 5. When the first armature 4 and the second armature 5 need to be installed, only need to first fixedly assemble the mounting seat 6 and the base 1. After the mounting seat 6 is fixedly installed, then insert the connecting piece 19 into the gap between the base 1 and the mounting seat 6. At this time, the first armature 4 and the second armature 5 can be fixedly installed. Since the connecting piece 19 itself has a certain elasticity, it will not cause any influence on the movement of the first armature 4 and the second armature 5.

[0040] In addition, in order to further improve the stability of the first armature 4 and the second armature 5 after installation, elastic pieces 18 are provided inside the two connecting pieces 19. Through the setting of the elastic pieces 18, the stability of the connection between the connecting piece 19 and the base 1 can be further improved, so that the stability of the first armature 4 and the second armature 5 after installation can be further improved.

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the descriptions in the specification are only preferred examples of the present utility model, and are not used to limit the present utility model.
