[0019] The plug structure 2 includes a connecting seat 3, and two conductive cavities 4 are respectively arranged on the left and right sides of the connecting seat 3. The two adjacent conductive cavities 4 on the same side are symmetrical in structure. The lower sides of the two conductive cavities 4 on the left and the upper sides of the two conductive cavities 4 on the right are respectively provided with a first through groove 5 and a second through groove 6. A conductor 7, a spring 8 and a support seat 9 are respectively arranged in any conductive cavity 4. A limiting rib 10 is arranged on the support seat 9. One end of the spring 8 is fixed to the support seat 9, and the other end of the spring 8 is facing the same conductive cavity. 4, one end of the conductor 7 in the same conductive cavity 4 is offset, the first through slot 5 is arranged above one end of the spring piece 8 in the same conductive cavity 4, an exit key 11 is arranged in the second through slot 6 in the same conductive cavity 4, a dovetail block 12 is respectively arranged on the upper right side and the lower left side of the connecting seat 3, a slide groove 13 is respectively arranged on the top and the bottom of the connecting seat 3, the length directions of the dovetail block 12 and the slide groove 13 are parallel to the length direction of the connecting seat 3, and two detection slots 14 are arranged on the front side of the connecting seat 3, and the detection slots 14 are respectively connected to the two conductive cavities 4,

[0020] A lampshade 15 is provided at the front end of the lamp housing 1, and a signal light is provided in the lampshade 15. The core structure 2 is provided at the rear side of the lamp housing 1. A dovetail groove 16 is provided on the left and right sides of the rear end of the lamp housing 1, and the dovetail groove 16 is slidably matched with the dovetail block 12. A slider 17 is provided on the inner side surfaces of the top and bottom of the rear end of the lamp housing 1, and the slider 17 is slidably matched with the slide groove 13. A rear cover is provided at the rear end of the lamp housing 1.

[0021] Furthermore, the cross section of the detection slot 14 is U-shaped.

[0022] Furthermore, the connecting seat 3 is made of a nylon block.

[0023] Specifically, the lampshade 15, signal light, spring 8, conductor 7, etc. in this embodiment all adopt well-known solutions in the prior art, which are well known to those skilled in the art and will not be described in detail here.

[0024] The working principle of this embodiment:

[0025] The single dovetail slide rail type core insertion structure signal lamp of the present invention separates the lamp housing 1 from the core insertion structure 2, and after the spring piece 8 and the conductor 7 are installed in the core insertion structure 2, the core insertion structure 2 is installed into the lamp housing 1. The core insertion structure 2 and the lamp housing 1 are fixed by sliding cooperation through the dovetail groove 16 and the dovetail block 12, and the slider 17 and the slide groove 13. The slide groove 13 and other structures are fixed to the signal lamp housing 1. Figure 5 and Figure 6As shown, the four degrees of freedom of rotation of the insert structure 2 in the X-axis, Y-axis, around the X-axis, and around the Y-axis are restricted. The lead wire 18 with the end is inserted through the first through slot 5 into the conductive cavity 4, and the spring piece 8 is forced to deviate from the original position. As the lead wire 18 is inserted deeper, the spring piece 8 clamps the end of the lead wire 18 by the reaction force, so that the lead wire 18 is connected with the conductor 7, and the signal lamp holder in the lamp housing 1 is energized, thereby realizing the wiring method of the spring piece 8 and the conductor 7, and improving the wiring efficiency.

[0026] When the lead 18 needs to be removed, the eject button 11 is pressed with a flat-blade screwdriver, and the eject button 11 further deforms the spring sheet 8, so that the end of the lead 18 is out of contact with the spring sheet 8, and then the lead 18 is pulled out to complete the removal.

[0027] The two conductive cavities 4 on the left and the two conductive cavities 4 on the right of the connector 3 adopt a "back-to-back" structure and a staggered asymmetric distribution structure to ensure that the conductive cavity 4 inside the plug structure 2 is sufficient to install the spring 8 and the conductor 7, and can control the signal lamp through two circuits, and can also serve as a backup, such as Figure 2 and Figure 3 shown.

[0028] After the conductor 7 is installed in the insert structure 2, the detection groove 14 allows the conductors 7 on both sides to be used for detection, which is convenient for process detection. Figure 4 shown.

[0029] The limiting rib 10 can limit the spring piece 8 to prevent the exit key 11 from falling out, and can also increase the strength of the insert structure 2.
