Detailed Description
The invention is shown in figures 1-2, and comprises a fixed plate 1, a movable plate 2, a reinforcing plate 3, a reinforcing spring 4, a plurality of fixed elastic pieces 5, a plurality of movable elastic pieces 6 and a plurality of reinforcing components 7;
the fixed plate 1 is fixedly connected in the ammeter, one end of the fixed plate is C-shaped, the movable plate 3 is slidably connected in the ammeter and positioned in the C-shaped, the fixed spring plates 5 are fixedly connected to the fixed plate 1 and are respectively positioned in the wiring holes of the ammeter, and the movable spring plates 6 are fixedly connected to the movable plate 2 and are respectively positioned in the wiring holes of the ammeter; in this way, the movable elastic sheet can freely slide in the wiring hole along the length direction of the movable plate;
the reinforcing plate 3 comprises a transverse plate 31 and a vertical plate 32 which are fixedly connected, the transverse plate 31 is slidably connected in the ammeter and is positioned at one side of the movable elastic sheet 6 far away from the fixed plate 1, the vertical plate 32 is perpendicular to the fixed plate 1 and is abutted against the fixed plate 1, and the reinforcing spring 4 is abutted between the movable plate 2 and the vertical plate 32; therefore, a certain pressure is applied to the movable plate through the reinforcing spring, and a force facing the fixed elastic piece is applied to the movable elastic piece before metal fatigue occurs to the movable elastic piece, so that the clamping force of the movable elastic piece and the fixed elastic piece to the external connector lug is effectively improved;
the reinforcing components 7 are in one-to-one correspondence with the wiring holes and comprise sliding blocks 71 and driving blocks 72, the sliding blocks 71 are slidably connected in the ammeter and are arranged on one side of the wiring holes far away from the fixed plate 1, wedge faces are formed in the tops of the sliding blocks 71, and the driving blocks 72 are fixedly connected to the transverse plate 31 and are located on one side of the sliding blocks 71 far away from the movable elastic sheet 6. Therefore, after the movable elastic sheet is subjected to metal fatigue (the appearance of the movable elastic sheet is that the external connector is loose and the measured data is not fixed), the external connector can be pushed continuously after the external connector is normally inserted, so that the external connector can continuously move inwards and jack up the sliding block, the reinforcing plate further presses the reinforcing spring under the drive of the driving block, and the clamping force between the movable elastic sheet and the fixed elastic sheet is effectively ensured.
The sliding block 71 is L-shaped; the wiring assembly further comprises a reset block 8, one end of the reset block 8 extends out of the ammeter and is fixedly connected with the movable plate 2, and the reset block 8 is located on one side, opposite to the reinforcing spring 4, of the movable plate 2. Therefore, after the external wire connector is inserted into and jacked up against the sliding block, the driving block can be driven to slide and be clamped into the L shape, so that the reinforcing plate is locked, and stable and effective clamping force is provided between the movable elastic sheet and the fixed elastic sheet; when the external connector needs to be pulled out, the reset block can be pressed to push the movable plate to press the reinforcing spring, so that the external connector is loosened, and the sliding block can be reset freely.
The fixed plate 1 is provided with a plurality of fixed holes 10 for accommodating the external connection terminals, the movable elastic pieces are sleeved in the fixed holes, the movable plate 2 is provided with a plurality of movable holes 20 for accommodating the external connection terminals, and the fixed elastic pieces are sleeved in the movable holes.
