[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0031] like Figure 1-Figure 6As shown, the utility model provides a terminal block with a length adjustment component, including a mounting plate 1, a gusset plate 2 is detachably mounted on the surface of the mounting plate 1, an isolation cover 3 is snap-connected on the surface of the gusset plate 2, a fixed frame 4 is fixed on the surface of the isolation cover 3 and is connected, an adjustment frame 5 is slidably connected to the inner wall of the fixed frame 4, a conductive plate 6 is fixedly connected to the surface of the gusset plate 2, an elastic sheet 7 is fixedly connected to the inner wall of the adjustment frame 5, the elastic sheet 7 is a copper sheet, the elastic sheet 7 is slidably connected to the conductive plate 6, a bolt 8 is rotatably connected in the isolation cover 3, a conductive frame 9 is threadedly connected to the arc surface of the bolt 8, the conductive frame 9 is slidably connected to the isolation cover 3, and the conductive plate 6 is fixedly connected to the inner wall of the adjustment frame 5. A plurality of friction grooves 11 are provided on the surface of the plate 6. By setting an adjustment frame 5 that slides along the inner wall of the fixed frame 4 to change the length of the adjustment frame 5 extending out of the fixed frame 4, the position of the elastic sheet 7 can be adjusted, thereby adjusting the contact position of the elastic sheet 7 and the cable to ensure that the cable and the elastic sheet 7 are in full contact and avoid poor contact. The elastic sheet 7 has a bent structure, and the bent structure of the elastic sheet 7 can facilitate the insertion of the cable between the two elastic sheets 7. A guide ring 10 is fixedly connected to the inner wall of the adjustment frame 5. The cross-section of the guide ring 10 is trapezoidal, and the guide ring 10 with a trapezoidal cross-section can guide the sliding path of the cable.
[0032] like Figure 2 and Figure 6 As shown, the surface of the fixed frame 4 is provided with a limiting structure 12, and the limiting structure 12 includes two fixing rods 121, and the fixing rods 121 are fixedly connected to the fixing frame 4. The surface of the fixing rod 121 is slidably connected with a slide plate 122, and the surface of the slide plate 122 is fixedly connected with a transmission plate 123, and the surface of the slide plate 122 is fixedly connected with a clamping plate 124. The surface of the adjustment frame 5 is provided with a plurality of clamping grooves 125, and the size of the clamping groove 125 is adapted to the size of the clamping plate 124. By setting the limiting structure 12, after the clamping plate 124 slides into the inner wall of the clamping groove 125, the clamping plate 124 reaches the function of limiting the position of the adjustment frame 5, thereby limiting the position of the elastic sheet 7, and the fixing rod 121 is in the form of a regular hexagonal prism structure, and the fixed rod 121 in the form of a regular hexagonal prism structure can limit the sliding path of the slide plate 122, thereby limiting the sliding path of the card plate 124. The surface of the fixed rod 121 is sleeved with a spring 126, and the two ends of the spring 126 are respectively fixedly connected to the slide plate 122 and the fixed rod 121. When the spring 126 is extended, the slide plate 122 will drive the card plate 124 to slide into the inner wall of the card slot 125 with the help of the elastic force of the spring 126. The spring 126 can automatically reset the card plate 124. The surface of the transmission plate 123 is provided with a plurality of anti-skid grooves 127, and the anti-skid grooves 127 can increase the surface friction of the transmission plate 123.
[0033] The overall working principle is that when it is necessary to change the position of the adjusting frame 5 in the fixed frame 4, the two transmission plates 123 are pinched, and the two transmission plates 123 will respectively drive the two slide plates 122 to slide in the direction away from each other, and the anti-slip groove 127 can increase the surface friction of the transmission plate 123. The slide plate 122 will compress the spring 126 while sliding along the surface of the fixed rod 121. The sliding of the slide plate 122 will also drive the card plate 124 to slide. At this time, the fixed rod 121 with a regular hexagonal prism structure can limit the sliding path of the slide plate 122, thereby limiting the sliding path of the card plate 124. When the card slot 125 is out of contact with the card plate 124, the adjusting frame 5 can be slid along the inner wall of the fixed frame 4. The sliding of the adjusting frame 5 will drive the elastic sheet 7 to slide. By adjusting the position of the elastic sheet 7, when the length of the cable is short, it can ensure that the cable is in full contact with the elastic sheet 7 to avoid poor contact. After the adjustment is completed, release the transmission. Plate 123, at this time, the spring 126 begins to stretch, and the slide plate 122 will use the elastic force of the spring 126 to drive the card plate 124 to slide into the inner wall of the card slot 125, and the card plate 124 reaches the limit adjustment frame 5 position, thereby limiting the role of the elastic sheet 7 position, and then a cable is inserted into the adjustment frame 5 along the surface of the guide ring 10. The sliding of the cable will push the two elastic sheets 7 open. In this process, the guide ring 10 with a trapezoidal cross-section can guide the sliding path of the cable, and the elastic sheet 7 with a bent structure can facilitate the cable to be inserted between the two elastic sheets 7. Then, another cable is inserted into the inner wall of the conductive frame 9, and then the bolt 8 is turned. The bolt 8 will drive the conductive frame 9 to slide with the help of the thread. The sliding of the conductive frame 9 will contact the cable and press the cable against the surface of the conductive plate 6. At this time, the two cables will contact the elastic sheet 7 and the conductive plate 6 respectively. At the same time, because the elastic sheet 7 is in contact with the conductive plate 6, the two cables can form a passage.
