[0021] The present utility model will be described in detail below with reference to the accompanying drawings.
[0022] As Figures 1 to 4As shown, a relay structure for contact detection of the utility model comprises a frame 1, wherein the frame 1 is provided with an electromagnetic component 2 and a contact component 3 used in conjunction with the electromagnetic component 2, wherein the contact component 3 comprises an A foot 31, a reed 32 used in conjunction with the A foot 31, a first detection hole 33 provided on the A foot 31, a second detection hole 34 provided on the reed 32, a static contact 35 provided on the A foot 31, and a moving contact 36 provided on the reed 32, wherein the reed 32 is pushed by the electromagnetic component 2 so that the moving contact 36 contacts the static contact 35, and the central axis of the first detection hole 33 coincides with the central axis of the second detection hole 34.
[0023] During the production process of the relay, it is necessary to complete the detection items of the neutrality and pressure value of the relay contact point. A first detection hole 33 is added to the A foot 31, and a second detection hole 34 is added to the reed 32. When the A foot 31 and the reed 32 are in contact with each other, the moving contact 36 contacts the static contact 35 accordingly. In this way, it is convenient for the external CCD detector to capture and detect the feature that the central axis of the first detection hole 33 coincides with the central axis of the second detection hole 34, so as to judge the neutrality between the moving contact 36 and the static contact 35, and the detection accuracy is high; the armature 21 is moved by the force meter, thereby causing the reed 32 to move, so that the moving contact 36 and the static contact 35 are in contact with each other, and the test probe passes through the first detection hole 33 of the A foot 31. When the reed 32 moves, it will touch the test probe to form a loop. The contact pressure value can be obtained by reading the force meter parameters. In the automatic line production, it is replaced by pressing the armature 21 with a weight to directly read the weight of the weight. The detection method is simpler, more convenient and more accurate. In terms of structural design, the utility model adds corresponding holes on the structure of the A foot 31 and the reed 32, simplifies the detection operation, makes the operation simple and convenient, facilitates the automatic production detection of the relay, improves the detection efficiency and detection accuracy, and meets the needs of large-scale detection.
[0024] In this embodiment, both sides of the A foot 31 are provided with a block 37, the block 37 is formed by protruding from the outer wall of the A foot 31, and both sides of the frame 1 are provided with a slot 11, the slot 11 is formed by recessing from the inner wall of the frame 1, and the block 37 is accommodated in the slot 11. Specifically, as a preferred embodiment, two blocks 37 are provided, and two slots 11 are provided, the two blocks 37 are formed by protruding from both sides of the A foot 31, and the two slots 11 are formed by recessing from both sides of the frame 1. When the two blocks 37 are correspondingly accommodated in the two slots 11, the connection between the A foot 31 and the frame 1 is fixed, and the connection is stable and reliable.
[0025] The aperture of the first detection hole 33 in this embodiment is larger than that of the second detection hole 34. Specifically, the aperture of the first detection hole 33 is larger than that of the second detection hole 34. When detecting the contact pressure value, the test probe passes through the first detection hole 33. When the reed 32 moves, it will touch the test probe to form a circuit, so as to accurately obtain the contact pressure value, and the detection accuracy is high.
[0026] One end of the frame body 1 in this embodiment close to the A pin 31 is provided with a support block 12, and the top surface of the support block 12 is flush with the bottom surface of the first detection hole 33. Specifically, a first detection hole 33 is added to the A pin 31, and the bottom surface of the first detection hole 33 is flush with the top surface of the support block 12. The support block 12 not only improves the supporting force for the test probe, but also can ensure being flush with the first detection hole 33. By observing the flatness between the first detection hole 33 and the support block 12, if the flatness of the two is consistent, it can be judged that the A pin 31 is assembled in place, otherwise it is judged that the A pin 31 cannot be assembled in place, and the detection is simple and efficient.
[0027] The electromagnetic component 2 in this embodiment includes an armature 21, an electromagnet 22 for attracting the armature 21, and a push piece 23 arranged on the armature 21. The electromagnet 22 pushes the push piece 23 via the armature 21, so that the push piece 23 drives the moving contact 36 of the reed 32 to contact and conduct with the static contact 35. Specifically, after being energized, the electromagnet 22 pushes the push piece 23 via the armature 21, so that the push piece 23 drives the moving contact 36 of the reed 32 to contact and conduct with the static contact 35, and the action has good coherence and smoothness, and the assembly stability is high.
