[0015] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0016] The accompanying drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0017] See also Figure 1-3 A steel core aluminum stranded wire crimping device comprises a base 1, a jack 2 is fixedly installed on the inner side of the base 1, a U-shaped plate 4 located above the jack 2 is rotatably connected to the inside of the base 1 through a fixing rod 3, a top plate 5 located on the inner side of the base 1 is fixedly installed on the top of the jack 2, a first pressing block 6 is placed on the top of the top plate 5, an internal threaded sleeve 7 is arranged in the middle of the top of the U-shaped plate 4, and a magnet 8 is arranged on the top of the inner side of the U-shaped plate 4, through which a second pressing block 9 can be adsorbed and fixed, so that the second pressing block 9 will not fall off during the crimping operation, so as to facilitate the movement of the crimping part of the stranded wire, a second pressing block 9 located directly above the first pressing block 6 is placed on the inner side of the U-shaped plate 4, a pull ring 10 is arranged on the outer side of the base 1, and the pull ring 10 is convenient for carrying the crimping device.

[0018] Among them, first slide rails 11 adapted to the top plate 5 and the first pressure block 6 are provided on both sides of the inner side of the base 1. The first slide rails 11 can be used to limit and guide the top plate 5 and the first pressure block 6, so that the top plate 5 and the first pressure block 6 will not be offset during the movement, thereby reducing the force acting on the jack 2.

[0019] Among them, both sides of the inner side of the U-shaped plate 4 are provided with second slide rails 12 adapted to the second pressure block 9, and the bottom of the second slide rail 12 is provided with a chamfer. The chamfer is set so that the first pressure block 6 can be easily stuck into the outer side of the second slide rail 12 during the closing process with the second pressure block 9, ensuring that the first pressure block 6 and the second pressure block 9 are not easily misaligned during the crimping operation. The internal movable sleeve of the U-shaped plate 4 is provided with a fixing pin 13 that is movably sleeved inside the base 1. The U-shaped plate 4 can be limited by the fixing pin 13, so that the twisted wire can be crimped when the first pressure block 6 and the second pressure block 9 are closed, and the limitation of the U-shaped plate 4 can be released by removing the fixing pin 13. At this time, the first pressure block 6 and the second pressure block 9 can be replaced by opening the U-shaped plate 4.

[0020] Among them, the internal threaded sleeve of the internal threaded sleeve 7 is connected with a support rod 14, through which a person can hold the support rod 14 by hand when manually pressing the jack 2, and then the support rod 14 is used to limit the crimping device while ensuring that the crimping device is not prone to shaking, so that the person can manually press the jack 2, and by removing the support rod 14, the space occupied by the crimping device can be reduced, so that the crimping device can be transported easily.

[0021] When the crimping device is in use, the fixing pin 13 is disassembled, the U-shaped plate 4 is opened by the support rod 14, and the connection of the stranded wire is placed on the inner side of the first pressure block 6, and the U-shaped plate 4 is closed by the support rod 14, and the fixing pin 13 is sleeved inside the base 1 and the U-shaped plate 4. At this time, the support rod 14 is held by hand and the jack 2 is manually pressed, and the first pressure block 6 is driven to move by the drive of the jack 2. As the first pressure block 6 gradually moves and the second pressure block 9 contacts with the stranded wire, the connection of the stranded wire is crimped by the extrusion force generated by the first pressure block 6 and the second pressure block 9. After the crimping is completed, the jack 2 is manually depressurized, and the first pressure block 6 will be driven to move downward under the action of the stranded wire's own gravity. At this time, the fixing pin 13 is disassembled, the U-shaped plate 4 is opened by the support rod 14, and the stranded wire is moved out from the inner side of the first pressure block 6 to complete the crimping operation of the stranded wire.
