Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connector crimping technology, and specifically to an electrical connector crimping device. Background Technology
[0002] Electrical connectors, also known as plugs, are electronic components primarily used to connect or disconnect electrical signals in circuits or electronic devices. They offer various forms of connection and signal transmission capabilities. For example... Figure 1 When the electrical connector 200 shown is connected to the wires of the wire harness, the multiple conductive elements 201 arranged in a ring within the electrical connector 200 are typically electrically connected to the wire portion of the wire harness via a crimping device.
[0003] Existing electrical connector crimping devices include a drive unit and a multi-jaw chuck, with a tapered engagement between the jaws of the drive unit and the multi-jaw chuck. The drive unit uses this tapered engagement to radially clamp the electrical connector and wire harness, forming an electrical connection. During crimping, the wire harness needs to maintain coaxiality with the electrical connector. However, existing crimping devices typically place the wires of both the electrical connector and the wire harness between multiple jaws, manually hold the remaining portion of the wire harness, and then drive the jaws to perform the crimping. This process can easily cause the wire harness to wobble relative to the electrical connector, affecting the coaxiality of the wire harness and the electrical connector, and consequently impacting the crimping effect.

[0005] A frame, on which a driving component is provided, and at the output end of the driving component is a pushing ring, the pushing ring having an outer conical surface;
[0006] A multi-jaw chuck includes a main body and multiple jaws slidably disposed on the main body. Each jaw has an inner conical surface adapted to an outer conical surface. The driving component is used to drive a push ring to pass into the main body, thereby causing the jaws to grip the electrical connector.
[0007] The frame is equipped with a rotary pressing cylinder, and the output end of the rotary pressing cylinder is equipped with a carrier. The carrier is connected to a gripper cylinder, and the output end of the gripper cylinder is equipped with two gripping blocks arranged opposite each other. The rotary pressing cylinder is used to drive the two gripping blocks to rotate to correspond with the gripper. The gripper cylinder is used to drive the two gripping blocks to cooperate in clamping the wire harness.
[0008] Furthermore, the clamping block includes a first block and a second block. The first block is connected to the output end of the gripper cylinder, and the second block has a semi-annular structure and is in contact with the outer periphery of the wire harness.

[0012] Furthermore, the second crimping block is provided with an arc-shaped surface that matches the outer periphery of the electrical connector.
[0013] The beneficial effects of this utility model are: by setting up a rotary pressing cylinder and a clamping cylinder, after the wires of the electrical connector and the wire harness are placed between multiple clamping claws, the rotary pressing cylinder cooperates with the clamping cylinder to clamp the rest of the wire harness, so that the wire harness is less likely to shake during the crimping process and affect the crimping effect.

Detailed Implementation
[0024] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0025] Please refer to Figure 2 , Figure 4 , Figure 7 and Figure 8 This utility model provides an electrical connector crimping device 100, including a frame 10 and a multi-jaw chuck connected to the frame 10. The frame 10 is provided with a driving member, and the output end of the driving member is provided with a push ring 11. The push ring 11 is provided with an outer conical surface 111.
[0026] Please refer to Figure 7 and Figure 8 The multi-jaw chuck includes a main body 20 and multiple jaws 21 slidably disposed on the main body 20. Each jaw 21 has an inner conical surface 211 adapted to an outer conical surface 111. A driving member drives a pushing ring 11 to penetrate the main body 20, thereby causing the jaws 21 to grip the electrical connector 200. Specifically, in this embodiment, the multi-jaw chuck is a three-jaw chuck, and the driving member is a hollow rotary cylinder (not shown in the figure). Three-jaw chucks are existing technology; therefore, this specification only provides illustrative descriptions of components related to the inventive point of this case, omitting other internal structures and working principles well known to those skilled in the art. During crimping, the electrical connector 200 and the wires of the wiring harness are placed between the multiple jaws 21. The driving member then drives the pushing ring 11 to push the jaws 21 to grip the electrical connector 200, causing the electrical connector 200 to deform and forming an electrical connection with the wires of the wiring harness.
[0027] Please refer to Figure 4 and Figure 5 The jaw 21 has a telescopic groove 212, within which a compression spring 23 is installed. The compression spring 23 is connected to a second crimping block 22, and the jaw 21 and the second crimping block 22 are elastically connected by the compression spring 23. The combination of the compression spring 23 and the second crimping block 22 allows the jaw 21 to adapt to crimping electrical connectors 200 of different diameters, improving the practicality of the electrical connector crimping device 100. The second crimping block 22 has an arc-shaped surface 221 that matches the outer periphery of the electrical connector 200. The arc-shaped surface 221 facilitates the application of force by the second crimping block 22 to the electrical connector 200.
[0028] Please refer to Figure 2 The frame 10 is equipped with a rotary pressing cylinder 30. The output end of the rotary pressing cylinder 30 is equipped with a carrier 31. The carrier 31 is connected to a gripper cylinder 32. The output end of the gripper cylinder 32 is equipped with two gripping blocks 33 arranged opposite to each other. The rotary pressing cylinder 30 is used to drive the two gripping blocks 33 to rotate to correspond with the gripper 21. The gripper cylinder 32 is used to drive the two gripping blocks 33 to cooperate and grip the wire harness.
[0029] By using the rotary pressing cylinder 30 and the clamping cylinder 32, after the electrical connector 200 and the wires of the wire harness are placed between multiple clamping jaws, the rotary pressing cylinder 30, in conjunction with the clamping cylinder 32, clamps the remaining part of the wire harness, thereby making it less likely for the wire harness to shake during the crimping process and thus affecting the crimping effect.
[0030] Please refer to Figure 2 The clamping block 33 includes a first block 331 and a second block 332. The first block 331 is connected to the output end of the gripper cylinder 32. The second block 332 has a semi-circular structure and fits snugly against the outer periphery of the wire harness. Specifically, the diameter of the ring formed by the two second blocks 332 is slightly smaller than the outer diameter of the wire harness, which facilitates the clamping blocks 33 to clamp the wire harness tightly and further reduces the likelihood of the wire harness shaking during crimping, thereby improving crimping efficiency.
[0031] Please refer to Figure 3 and Figure 6 The frame 10 is provided with a positioning ring 12 that is concentric with the center of the multi-jaw chuck. The carrier 31 is provided with a positioning block 311. The positioning ring 12 is provided with a positioning groove 121 that is adapted to the positioning block 311. The rotating pressing cylinder 30 is used to drive the positioning block 311 to be inserted into the positioning groove 121.
[0032] When clamping the wire harness, the rotary pressing cylinder 30 drives the two clamping blocks 33 to rotate until the positioning block 311 and the positioning groove 121 correspond. The rotary pressing cylinder 30 then drives the two clamping blocks 33 to descend, and the positioning block 311 engages in the positioning groove 121. At this time, the clamping centers of the two clamping blocks 33 correspond to the center of the multi-jaw chuck. The positioning blocks 311 and the positioning groove 121 facilitate the positioning of the clamping position of the two clamping blocks 33 on the wire harness, so that the rotary pressing cylinder 30 can drive the two clamping blocks 33 to move to a position concentric with the electrical connector 200, thereby facilitating the coaxial arrangement of the wire harness and the electrical connector 200.
[0033] Please refer to Figure 3 and Figure 4 The positioning ring 12 is provided with a guide block 13, and the guide block 13 has a guide cone hole 131 corresponding to the center of the multi-jaw chuck. Specifically, the diameter of the guide cone hole 131 at the end near the multi-jaw chuck is smaller than the diameter of the guide cone hole 131 at the end away from the multi-jaw chuck. The guide cone hole 131 guides the electrical connector 200 and the wire harness to the center of the multi-jaw chuck.
[0034] For details, please refer to Figure 4 and Figure 5 The end of the outer conical surface 111 closer to the guide block 13 is closer to the central axis of the push ring 11 than the end of the outer conical surface 111 farther from the guide block 13.
