Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] The embodiment of the present invention provides a connection contact for busbar safety regulations detection:

[0021] Embodiment 1, as shown in Figure 1 、 3 、4, includes a fixed frame 1. A plurality of sliding plates 2 are slidably connected inside the fixed frame 1. A "U"-shaped elastic conductive sheet 3 is fixedly installed on the upper surface of the sliding plate 2. A cable 4 is fixedly installed at the bottom end of the elastic conductive sheet 3. The cable extends below the fixed frame 1. An extrusion mechanism 5 for deforming the elastic conductive sheet 3 is fixedly installed above the fixed frame 1. The extrusion mechanism 5 is located outside the elastic conductive sheet 3. The extrusion mechanism 5 includes a support sleeve 511. A rack plate 512 is slidably connected inside the support sleeve 511. One end of the rack plate 512 close to the elastic conductive sheet 3 is fixedly installed with a first extrusion plate 513. The first extrusion plate 513 can extrude the elastic conductive sheet 3 to be closely attached to the busbar connection terminal after moving. A gear 514 is engaged with the meshing end of the rack plate 512 inside the support sleeve 511. A worm gear 515 concentric with the gear 514 is fixedly installed below the gear 514. A worm 516 is engaged with the edge of the worm gear 515. The transmission between the worm 516 and the worm gear 515 has a self-locking function, which can avoid the deformation recovery of the elastic conductive sheet 3. A rotating shaft 517 is fixedly installed in the middle of the worm 516. The rotating shaft 517 extends outside the support sleeve 511. The number of the rack plates 512 is multiple, and the multiple rack plates 512 are equidistantly distributed. The rotating shaft 517 is fixedly connected with a plurality of worms 516. Through such a setting, the force can be evenly distributed. By rotating the rotating shaft 517, the worm 516 can be driven to rotate. By using the cooperation of the worm 516 and the worm gear 515, self-locking can be realized. Furthermore, the gear 514 can be used to drive the rack plate 512 to move, so that the first extrusion plate 513 extrudes the elastic conductive sheet 3.

[0022] Embodiment 2, as shown in Figure 1 and 2As shown, it includes a fixed frame 1. Inside the fixed frame 1, multiple sliding plates 2 are slidably connected. On the upper surface of the sliding plate 2, a "U"-shaped elastic conductive sheet 3 is fixedly installed. At the bottom end of the elastic conductive sheet 3, a cable 4 is fixedly installed. The cable extends below the fixed frame 1. Above the fixed frame 1, a pressing mechanism 5 for deforming the elastic conductive sheet 3 is fixedly installed. The pressing mechanism 5 is located outside the elastic conductive sheet 3. The pressing mechanism 5 includes a second pressing plate 521. The second pressing plate 521 is arranged on both sides of the elastic conductive sheet 3. On the side of the second pressing plate 521 away from the elastic conductive sheet 3, a rotating plate 522 is fixedly installed. The rotating plate 522 is equivalent to a lever. Through such a setting, a better clamping effect can be achieved with a smaller force at the distal end. On both sides of the rotating plate 522, a support frame 523 is rotatably connected. The support frame 523 is fixedly connected to the sliding plate 2. At the end of the rotating plate 522 away from the second pressing plate 521, a pressing head 524 is fixedly installed.

The sliding friction groove 526 can position the pressing block 525 through the friction force with the pressing block 525. By sliding the pressing block 525 to press the pressing head 524, the rotating plate 522 can be driven to swing, and then the second pressing plate 521 can be made to press the elastic conductive sheet 3.

[0023] When in use, by setting the "U"-shaped elastic conductive sheet 3, the wiring end of the busbar can be inserted into the middle of the elastic conductive sheet 3, thereby increasing the contact area.
