Technical Field

[0001] This utility model relates to the field of electrical wiring equipment technology, specifically a crimping pliers with replaceable crimp interfaces. Background Technology

[0002] Self-adjusting crimping pliers are tools used to connect conductors such as wires and cables. They utilize mechanical structures and mechanical principles to apply pressure through the handle, causing the crimping die to squeeze the wire connector or terminal, thereby achieving a reliable electrical connection and mechanical fixation. They can automatically adjust the crimping force and stroke according to the thickness or diameter of the object being crimped, ensuring consistent quality in each crimp.

[0003] The existing technology has the following problems:

[0004] Although self-adjusting crimping pliers can automatically adjust the crimping force and stroke, each model of crimping pliers usually still has a certain range of applicability. For some special specifications or extra-large or extra-small wire connectors or terminals, they may not provide ideal crimping results, requiring the replacement of crimping pliers of different specifications. This affects work efficiency to some extent. Furthermore, when crimping different materials and specifications, the strength of the material and specifications will result in a greater crimping strength, requiring greater pressure to complete the crimping work, making the crimping more difficult. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a crimping pliers with replaceable crimping interfaces, solving the problems of poor applicability and high crimping difficulty.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a crimping pliers with replaceable crimping interfaces includes a crimping pliers body, a gripping handle is provided at the right end of the crimping pliers body, and a crimping component is provided at the left end of the crimping pliers body.

[0007] Preferably, the crimping component includes two parallel guide support plates. Two crimping molds are slidably connected to the opposite ends of the two guide support plates away from the crimping pliers body. The two crimping molds are mirror images of each other and parallel to each other. Quick-connect components are movably connected to the opposite sides of the two crimping molds. Two parallel crimping connecting rods are rotatably connected to the outer surface of the quick-connect components. The end of the crimping connecting rod away from the quick-connect components is connected to the output end of the crimping pliers body.

[0008] Preferably, the quick-connect assembly includes a support cylinder, inside which a support spring is provided. A pop-out connector is fixedly connected to both the upper and lower ends of the support spring. The outer surface of the pop-out connector is slidably connected to the inner side of the support cylinder. The end of the pop-out connector away from the support spring can slide to the outer side of the support cylinder. A smooth selection groove is formed on the outer surface of the pop-out connector, and several rotating beads move within the smooth selection groove. The outer surface of the rotating beads simultaneously contacts the inner side of the pressing mold and the inner wall of the support cylinder. Several positioning blocks that can enter the pressing mold are fixedly connected to the side of the outer surface of the pop-out connector away from the support spring. A press-to-unlock head is provided at the end of the pop-out connector away from the support spring. A guide support ridge is fixedly connected to the outer surface of the press-to-unlock head. A guide support groove is formed inside the guide support plate for the press-to-unlock head to slide with the guide support ridge.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a technical solution: a crimping pliers with replaceable crimp connectors includes a crimping pliers body 2, a gripping handle 3 is provided at the right end of the crimping pliers body 2, and a crimping component 1 is provided at the left end of the crimping pliers body 2. During the use of the crimping pliers, the gripping handle 3 controls the crimping pliers body 2 to crimp the wires to the crimping component 1.

[0024] The crimping pliers body 2 can transmit the force applied by the gripping handle 3 to the crimping component 1, so that the crimping component 1 can perform crimping work. This is existing technology and will not be explained here.

[0025] Please see Figure 2 The crimping component 1 includes two parallel guide support plates 11. Two crimping molds 14 are slidably connected to the opposite ends of the two guide support plates 11 away from the crimping pliers body 2. The two crimping molds 14 are mirror images of each other and parallel to each other. Quick-connect components 13 are movably connected to the opposite sides of the two crimping molds 14. Two parallel crimping rods 12 are rotatably connected to the outer surface of the quick-connect components 13. The end of the crimping rod 12 away from the quick-connect components 13 is connected to the output end of the crimping pliers body 2.

[0026] During the crimping operation, when the crimping pliers body 2 is subjected to the external force transmitted by the gripping handle 3, the output end of the crimping pliers body 2 drives the crimping linkage 12 to move, and the quick-connect assembly 13 moves synchronously with the crimping linkage 12. The two crimping dies 14 are pushed closer and closer to squeeze the wire connector or terminal located between them, completing the crimping work.

[0027] Please see Figure 3 The quick-connect assembly 13 includes a support cylinder 137, inside which a support spring 138 is provided. Pop-out connectors 136 are fixedly connected to both the upper and lower ends of the support spring 138. The outer surface of the pop-out connector 136 is slidably connected to the inner side of the support cylinder 137. The end of the pop-out connector 136 away from the support spring 138 can slide to the outer side of the support cylinder 137. A smooth selection groove is formed on the outer surface of the pop-out connector 136, and several rotating beads 135 move within the smooth selection groove. The outer surface of the rotating beads 135 simultaneously contacts the inner side of the pressing mold 14 and the inner wall of the support cylinder 137. A plurality of positioning blocks 134 that can enter the inside of the pressing mold 14 are fixedly connected to the outer surface of the pop-out connector 136 away from the support spring 138. A pressing unlock head 132 is provided at the end of the pop-out connector 136 away from the support spring 138. A guide support rib 133 is fixedly connected to the outer surface of the pressing unlock head 132. A guide support groove 131 is opened inside the guide support plate 11 for the pressing unlock head 132 to slide with the guide support rib 133. The end of the pressing unlock head 132 away from the pop-out connector 136 extends to the outside of the guide support plate 11.

[0028] When replacing the crimping die 14 using crimping pliers, the operator presses the release head 132, causing the guide support rib 133 to slide up and down within the guide support groove 131 of the guide support plate 11. As the release head 132 moves, the pop-out connector 136 slides within the support cylinder 137 and compresses the support spring 138, causing the positioning block 134 to be pulled out of the crimping die 14. At this point, the old crimping die 14 can be removed. When installing the new crimping die 14, align it, release the release head 132, and the support spring 138 rebounds, pushing the pop-out connector 136 to slide outwards from the support cylinder 137. The positioning block 134 enters the new crimping die 14 and is fixed in place. The rotating ball 135 rolls within the smooth groove of the pop-out connector 136, assisting in the relative movement of the pop-out connector 136 with the crimping die 14 and the support cylinder 137, ensuring a smooth replacement process and enabling a quick replacement of the crimping die 14.

[0029] Please see Figure 3 Pressing the end of the unlocking head 132 near the pop-out connector 136 allows it to enter the outer surface of the pop-out connector 136. The lower side of the outer surface of the unlocking head 132 is conical.

[0030] The conical pressing unlock head 132 can be ejected when the pressing mold 14 passes by, so that the pressing mold 14 can pass by and the replacement can be completed smoothly.

[0031] Please see Figure 4 The grip handle 3 includes two sliding grips 34, which are mirror images of each other and rotatably connected to the right end of the crimping pliers body 2. The outer surfaces of the sliding grips 34 are slidably connected to the crimping pliers handles 31. The two sliding grips 34 are provided with a locking rod 32 and an adjustment knob 33 on opposite sides.

[0032] The clamp handle 31 can drive the sliding handle 34 to transmit the clamping force to the clamp body 2. The locking rod 32 can work with the sliding handle 34 to fix the opening and closing angle and maintain the clamping state. The adjustment knob 33 can adjust the clamping force to ensure the consistency of the clamping force.

[0033] Please see Figure 4 The sliding grip 34 includes two parallel sliding plates 341. A connecting post 343 is fixedly connected to the middle of the opposite sides of the two sliding plates 341. A limit post 344 is fixedly connected to the opposite ends of the two sliding plates 341 away from the crimping pliers body 2. A fixing button 342 is rotatably connected to the opposite ends of the two sliding plates 341 near the crimping pliers body 2.

[0034] Please see Figure 4-5The clamp grip 31 includes a grip body 311. The grip body 311 has a sliding groove 312 for sliding the connecting post 343, and a sliding groove 313 for sliding the fixing button 342. The sliding groove 312 and the sliding groove 313 communicate with each other, and the width of the sliding groove 312 is greater than that of the sliding groove 313.

[0035] The sliding of the connecting post 343 in the second sliding groove 313 extends the force arm of the grip body 311. Based on the lever principle, the difficulty of pressing and applying force is reduced. After the connecting post 343 slides, it can enter the channel between the grip body 311 and the fixing button 342. When the fixing button 342 fixes the locking rod 32, the fixing button 342 can squeeze the connecting post 343 to fix the position of the grip body 311. The sliding of the limiting post 344 and the first sliding groove 312 can ensure that the grip body 311 will not detach from the sliding grip bar 34.

[0036] Please see Figure 1-5 At work:

[0037] According to the specifications of the wire connector or terminal, select the appropriate crimping mold 14. Press the unlocking head 132 with your finger. The guide support ridge 133 slides in the guide support groove 131, popping out the connector 136 and compressing the support spring 138. The positioning block 134 is pulled out from the original crimping mold 14, and the old mold is removed. After aligning the new mold with the installation position, release the unlocking head 132. The support spring 138 rebounds, pushing the positioning block 134 into the new mold for fixation, completing the mold replacement. Rotate the adjustment knob. Button 33 adjusts the grip pressure; the locking rod 32, in conjunction with the sliding grip rod 34, fixes the opening and closing angle of the crimping pliers; if the lever arm needs to be adjusted, the sliding connecting column 343 is moved to disengage it from the moving slide groove 313, the handle body 311 is moved, and after adjustment, the fixing button 342 is rotated again to fix it. Hold the crimping pliers handle 31 and apply force to the grip handle 3. The crimping pliers body 2 drives the crimping connecting rod 12 to move, and the quick-connect component 13 pushes the crimping mold 14 closer to squeeze the wire connector or terminal to complete the crimping work.
