[0002] The magnetic latching relay is a new type of relay developed in recent years. It is also an automatic switch. Like other electromagnetic relays, it automatically connects and disconnects the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay is completely dependent on the action of the permanent magnet, and the conversion of its switch state is completed by triggering a pulse electrical signal of a certain width. During the production process, it is necessary to conduct visual appearance inspection of the working conditions of the internal components of the magnetic latching relay to discover existing defects and solve them in time. Therefore, before each visual appearance inspection, the entire magnetic latching relay needs to be disassembled to understand the specific situation.

[0024] The utility model is described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 3 As shown, the utility model is a magnetic holding relay structure that is easy to visually detect, including a frame 1, the frame 1 is provided with an electromagnetic component 2 and a contact component 3 used in conjunction with the electromagnetic component 2, the frame 1 is provided with a first detection slot 11 at one end close to the electromagnetic component 2, and the frame 1 is provided with a second detection slot 12 at one end close to the contact component 3, the first detection slot 11 and the second detection slot 12 are used for visual appearance detection by an external CCD detector.

[0026] The electromagnetic component 2 and the contact component 3 are respectively installed at the two ends of the frame 1. After the electromagnetic component 2 is energized, it will generate an electromagnetic effect and attract the contact component 3, thereby triggering the mutual conduction between the contact components 3, and then playing the role of an automatic switch that uses a small current to control the operation of a large current. In addition, a first detection groove 11 is arranged at one end of the frame 1 close to the electromagnetic component 2, and a second detection groove 12 is arranged at one end of the frame 1 close to the contact component 3. Under the premise of not affecting the structural stability of the frame 1, the first detection groove 11 and the second detection groove 12 are opened on the frame 1 to reduce the weight of the frame 1, so as to facilitate the external CCD detector to perform automatic visual inspection of the work of the electromagnetic component 2 and the contact component 3, and can detect whether the working parts of the electromagnetic component 2 have poor contact, and whether the contacts of the contact component 3 have abnormal contact, so that the internal parts can be visually inspected without disassembling the frame 1, which saves time and effort and is convenient and quick to inspect. In addition, an external fan or air gun can be used to blow the first detection slot 11 and the second detection slot 12 for dust removal and cleaning, and effectively blow away the dust and debris attached to the first detection slot 11 and the second detection slot 12 and discharge them outside the frame. The utility model not only facilitates automated visual inspection work and improves inspection efficiency without disassembly, but also reduces the weight of the structure and improves the structural stability.

[0027] The electromagnetic assembly 2 of this embodiment includes a coil frame 21, a coil 22 sleeved on the outside of the coil frame 21, a yoke 23 arranged on the coil frame 21, an armature assembly 24 rotatably arranged on the frame 1, and a pusher 25 arranged on the armature assembly 24. The coil 22 attracts the armature assembly 24 to rotate relative to the frame 1 through the yoke 23, so that the armature assembly 24 drives the pusher 25 to conduct the contact assembly 3. Specifically, the coil 22 is sleeved on the outside of the coil frame 21, so when currents in different directions are applied to the coil 22, the yokes 23 arranged at both ends of the coil frame 21 generate electromagnetic forces on the armature assembly 24, prompting the armature assembly 24 to rotate counterclockwise or clockwise relative to the frame 1, so that the armature assembly 24 drives the pusher 25 to translate, so as to achieve the effect of conducting or disconnecting the contact assembly 3. Since the yoke 23 and the armature assembly 24 of the relay achieve the effect of switching the switch through the combined action of magnetic attraction and repulsion, the magnetic latching relay has a low requirement for the magnetic force of the pusher 25 and has high working reliability.

[0028] In this embodiment, two yokes 23 are provided, and the two yokes 23 are respectively provided at the two ends of the coil skeleton 21. The top of the frame 1 is provided with a first positioning block 13 and a second positioning block 14, and the first positioning block 13 and the second positioning block 14 are arranged at intervals, and the outer wall of the first positioning block 13 and the outer wall of the second positioning block 14 respectively abut against the two sides of one yoke 23, and the bottom of the frame 1 is provided with a third positioning block 15 and a fourth positioning block 16, and the third positioning block 15 and the fourth positioning block 16 are arranged at intervals, and the outer wall of the third positioning block 15 and the outer wall of the fourth positioning block 16 respectively abut against the two sides of another yoke 23. Specifically, the two yokes 23 are respectively provided at the two ends of the coil skeleton 21, and the outer wall of the first positioning block 13 and the outer wall of the second positioning block 14 respectively abut against the two sides of one yoke 23, and the outer wall of the third positioning block 15 and the outer wall of the fourth positioning block 16 respectively abut against the two sides of another yoke 23, so as to better fix the positions of the two yokes 23 on the frame 1, and the positioning effect is good.

[0029] The armature assembly 24 of this embodiment includes a rotating seat 241, a first armature 242 and a second armature 243 arranged on the rotating seat 241, a pushing arm 244 arranged on the rotating seat 241, and a rotating block 245 arranged on both sides of the rotating seat 241. The first armature 242 and the second armature 243 are arranged in parallel and spaced apart so that the yoke 23 is located between the first armature 242 and the second armature 243. The first detection groove 11 and the yoke 23, the first armature 242, and the second armature 243 are arranged opposite to each other. The pushing arm 244 is extended in a direction away from the rotating seat 241, and the frame 1 is provided with a connecting hole 17 connected to the rotating block 245. Specifically, the yoke 23 is located between the first armature 242 and the second armature 243. When the coil 22 is energized, an electromagnetic force is generated through the yoke 23 to attract the first armature 242 or the second armature 243. The rotating seat 241 is connected to the connecting hole 17 through the rotating block 245, thereby driving the rotating seat 241 to rotate relative to the frame 1. The rotating rotating seat 241 uses the pushing arm 244 to horizontally push the pushing member 25 to achieve the effect of turning on or off the contact assembly 3. The structure is compact and the design is reasonable, the transmission efficiency is high, and the first detection slot 11 is arranged relative to the yoke 23, the first armature 242, and the second armature 243. It is more convenient for an external CCD detector to obtain the working conditions between the yoke 23, the first armature 242, and the second armature 243 through the first detection slot 11, and to promptly detect whether there is poor contact.

[0030] The contact assembly 3 of this embodiment includes an A foot 31, a spring sheet 32 ​​spaced apart from the A foot 31, a static contact 33 disposed on the A foot 31, and a moving contact 34 disposed on the spring sheet 32. The spring sheet 32 ​​is pushed by the pusher 25 so that the moving contact 34 contacts the static contact 33. The second detection slot 12 is disposed opposite to the moving contact 34 and the static contact 33. Specifically, the spring sheet 32 ​​is pushed by the pusher 25 so that the moving contact 34 contacts and conducts with the static contact 33. Moreover, the second detection slot 12 is disposed opposite to the moving contact 34 and the static contact 33. It is more convenient for an external CCD detector to obtain the working conditions between the moving contact 34 and the static contact 33 through the second detection slot 12, and timely discover whether there is abnormal contact of the contacts.
