Description

Technical Field

[0001] The utility model relates to the technical field of charging pile production, in particular to a crimping block for charging pile cables. Background Art

[0002] When the charging cable on the charging pile is connected to the power output terminal in the charging pile, the wire core needs to be crimped with a wire lug. In the existing technology, hydraulic wire crimping pliers are generally used to crimp the wire lug. Two pressing blocks are placed in the clamp head of the hydraulic wire crimping pliers. One side of the pressing block is provided with an isosceles trapezoidal notch. When the two pressing blocks are put together, the two notches form a regular hexagon, thereby pressing the wire core tightly into the wire lug. Figure 4 The figure shows the state of the pressing block in the prior art during the pressing process. Figure 4 It can be seen that during crimping, the outer diameter of the wire nose 4 is larger than the diameter of the inscribed circle of the regular hexagon, and both sides of the wire nose 4 are located outside the isosceles trapezoidal notch. This results in the part of the wire nose 4 located outside the isosceles trapezoidal notch being pressed out with wings after crimping, which is very unsightly. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a crimping block for charging pile cables in response to the above-mentioned technical deficiencies.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a crimping block for a charging pile cable, comprising a first pressing block and a second pressing block, the first pressing block comprising a mother block, a first V-shaped groove being provided in the middle of one side of the mother block, the angle between the two side surfaces of the first V-shaped groove being 120°, first sliding surfaces being provided on both sides of the first V-shaped groove, the two first sliding surfaces respectively forming an angle of 150° with the two side surfaces of the first V-shaped groove, the two first sliding surfaces being slidably connected to two sliders, the side of the two sliders close to each other being an extrusion surface perpendicular to the first sliding surface, the side of the slider away from the first sliding surface being provided with a pushing surface, the angle between the pushing surface and the extrusion surface being 60°, a second V-shaped groove being provided on one side of the second pressing block, the angle between the two side surfaces of the second V-shaped groove being 120°.

[0005] To further optimize the technical solution, a limiting surface is provided on the side of the first sliding surface away from the first V-groove, and the angle between the limiting surface and the first sliding surface is 150°. When the limiting surface contacts the side surface of the second V-groove, the first V-groove, the second V-groove and the two extrusion surfaces form a pressing profile with a regular hexagonal cross-section.

[0006] To further optimize this technical solution, a guide groove with a T-shaped cross section is provided on the first sliding surface, the side of the slider close to the first sliding surface is a second sliding surface, and a guide block cooperating with the guide groove is provided on the second sliding surface.

[0007] Compared with the prior art, the utility model has the following advantages: a first V-shaped groove is provided in the middle of one side of the mother block on the first pressure block, and a first sliding surface is provided on both sides of the first V-shaped groove. The first sliding surface is slidably connected to a slider, and the slider is provided with an extrusion surface and a pushing surface. In the process of the first pressure block and the second pressure block approaching each other, the second V-shaped groove on the second pressure block can interact with the pushing surface so that the two sliders also approach each other, thereby pressing the wire nose to the end of the wire core, and no flying wing will appear on the wire nose, which is more beautiful.

[0013] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0014] Specific implementation method: Figure 1-3As shown, a crimping block for a charging pile cable includes a first pressing block 1 and a second pressing block 2, the two pressing blocks forming a pair, the first pressing block 1 including a mother block 11, a first V-shaped groove 111 being provided in the middle of one side of the mother block 11, the angle between the two side surfaces of the first V-shaped groove 111 being 120 degrees, a first sliding surface 112 being provided on both sides of the first V-shaped groove 111, the two first sliding surfaces 112 forming an angle of 150 degrees with the two side surfaces of the first V-shaped groove 111, the two first sliding surfaces 112 being respectively slidably connected to two sliders 12, the two sliders 12 being close to each other. The side is an extrusion surface 121 perpendicular to the first sliding surface 112, so the angle between the extrusion surface 121 and the side of the first V-shaped groove 111 is 120°, and the side of the slider 12 away from the first sliding surface 112 is provided with a pushing surface 122, and the angle between the pushing surface 122 and the extrusion surface 121 is 60°. A second V-shaped groove 21 is provided on one side of the second pressing block 2, and the angle between the two side surfaces of the second V-shaped groove 21 is 120°. When the first pressing block 1 and the second pressing block 2 are close to each other to a certain distance, the two pushing surfaces 122 can respectively fit with the two side surfaces of the second V-shaped groove 21.

[0015] Furthermore, a limiting surface 113 is provided on the side of the first sliding surface 112 away from the first V-shaped groove 111, and the angle between the limiting surface 113 and the first sliding surface 112 is 150°. When the limiting surface 113 contacts the side of the second V-shaped groove 21, the first V-shaped groove 111, the second V-shaped groove 21 and the two extrusion surfaces 121 form a pressing profile 3 with a regular hexagonal cross-section. At this time, the first pressing block 1 and the second pressing block 2 cannot continue to approach each other.

[0016] Specifically, a guide groove 114 with a T-shaped cross-section is provided on the first sliding surface 112, and the extension direction of the guide groove 114 is perpendicular to the symmetry plane of the first V-shaped groove 111. The side of the slider 12 close to the first sliding surface 112 is a second sliding surface 123, and the second sliding surface 123 is perpendicular to the extrusion surface 121. A guide block 124 that cooperates with the guide groove 114 is provided on the second sliding surface 123.

[0017] When in use, first place the first pressing block 1 and the second pressing block 2 in the clamp head of the hydraulic wire crimping pliers, and then push the two sliders 12 to the two sides of the mother block 11 respectively, so that the sliders 12 are located on the outside of the first V-shaped groove 111, and then put the wire nose with the wire core inserted between the two pressing blocks, and make the wire nose close to the two sides of the first V-shaped groove 111. At this time, the two extrusion surfaces 121 are a certain distance away from the wire nose (on both sides). Then operate the hydraulic wire crimping pliers to make the two pressing blocks approach each other. When the first sliding surface 112 contacts the side of the second V-shaped groove 21, the two extrusion surfaces 121 have not yet contacted the wire nose. Then the two sliders 12 will approach each other. When the limiting surface 113 contacts the side of the second V-shaped groove 21, the wire nose is crimped to the end of the wire core. Then make the two pressing blocks move away from each other, and the wire nose crimped to the end of the wire core can be pulled out from between the two pressing blocks. There will be no flying wing on the wire nose, which is more beautiful.

[0018] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
