Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a wiring harness terminal crimping tool. Background Art

[0002] Some automotive components require wiring harnesses for connection. During the manufacturing process of automotive steering systems, wiring harnesses need to be designed and manufactured for each ECU on each platform.

[0003] Terminal crimping is an important step in the wiring harness production process. The quality of the terminal crimping directly determines the quality of the wiring harness. Therefore, the crimping of the wiring harness terminals requires a standardized pressing method to ensure reliable terminal crimping quality.

[0004] Currently, terminal crimping is primarily performed manually using tools. Tool inadequacy and the unreliability of manual crimping lead to quality issues during the process, even causing wire harness disconnections during vehicle operation. Wire harness terminal crimping suffers from low efficiency and unreliable quality, making it difficult to guarantee both the speed and quality of wire harness production.

[0005] Therefore, it is necessary to design a wire harness terminal crimping tool to improve the efficiency, quality and stability of wire harness terminal crimping. Summary of the Invention

[0009] A pressure sensor unit is provided at the connection between the press rod and the upper clamp, a pressure gauge is installed on the rear side of the support seat, and a signal output end of the pressure sensor unit is connected to a signal input end of the pressure gauge.

[0010] There are five profiling grooves on the upper surface of the terminal, five profiling grooves on the lower surface of the terminal and five wiring harness grooves.

[0011] The upper clamp and the press rod, the lower clamp and the bottom plate are all fixed with screws.

[0012] The lower clamp and the wire pressing plate are fastened by screw two.

[0013] Compared with the existing technology, the utility model designs a wire harness terminal crimping tool, which can realize the simultaneous crimping of multiple wire harnesses, thereby improving the crimping efficiency; the lever-type downward pressing handle facilitates the control of the crimping force, ensures the crimping quality and stability, reduces the overall time consumption of the bottleneck step in wire harness production, and improves the overall efficiency of wire harness production.

[0017] The present invention will now be further described with reference to the accompanying drawings.

[0018] See also Figure 1 、 Figure 2 and Figure 3 The utility model is a wire harness terminal crimping tool, including a pressing handle, a spring, a pressing guide device, a wire pressing plate, an upper clamp, a lower clamp, a bottom plate, a support seat, and a pressing rod. The bottom plate 7 is equipped with a lower clamp 4 and a support seat 6. The lower clamp 4 is located in front of the support seat 6. The top of the lower clamp 4 is away from the end of the support seat 6. The wire pressing plate 5 is covered. The front side of the top of the support seat 6 is provided with a pressing guide device 2. The middle part of the pressing rod 8 passes through the pressing guide device 2. The upper end of the pressing rod 8 is connected to the lower pressing guide device 2. The middle part of the handle 1 is connected by a rotating shaft 1, and the tail of the pressing handle 1 is connected to the top connecting piece of the support seat 6 by a rotating shaft 2. The outer sleeve of the pressing rod 8 is provided with a spring 9, and the two ends of the spring 9 respectively press against the upper end boss of the pressing rod 8 and the inner surface of the pressing guide device 2. The lower end of the pressing rod 8 is installed with an upper clamp 3 corresponding to the position of the lower clamp 4. The bottom of the upper clamp 3 is provided with several terminal upper surface profiling grooves, and the top of the lower clamp 4 is provided with several terminal lower surface profiling grooves and several wiring harness grooves.

[0019] Since the force required for crimping the wiring harness terminals is not large, the pressing handle 1 adopts a manual lever structure, and the wiring harness terminals can be crimped by a combination of manual force and lever.

[0020] The pressing guide device 2 is a tubular structure. The pressing guide device 2 is convenient for controlling the stroke and trajectory of the pressing rod 8, ensuring that the pressing force can act vertically above the clamp.

[0021] When crimping different wiring harness terminals, it is only necessary to replace the corresponding upper clamp 3 and lower clamp 4.

[0022] A pressure sensor unit 10 is installed at the connection between the press-fitting rod 8 and the upper clamp 3. A pressure gauge 11 is mounted on the rear side of the support base 6. The signal output of the pressure sensor unit 10 is connected to the signal input of the pressure gauge 11. The pressure sensor unit 10 and pressure gauge 11 are provided to further control the crimping force. The pressure sensor unit 10 monitors the force during the crimping process and displays it on the pressure gauge 11. When press-fitting different terminals, the operator can check the value displayed on the pressure gauge 11 based on the recommended crimping force value for that terminal and adjust the hand force applied to the depressing handle 1.

[0023] The contoured design of the upper and lower clamps 3 and 4 solves the problem of positioning and fastening the terminals 13, avoiding the need for an additional terminal fixing mechanism. The upper clamp 3 and the press rod 8, and the lower clamp 4 and the base plate 7 are all fixed with screws, making it easy to replace different upper and lower clamps 3 and 4.

[0024] Preferably, there are five profiling grooves on the upper surface of the terminal, five profiling grooves on the lower surface of the terminal, and five wiring harness grooves, so that the terminals of five wiring harnesses can be crimped at one time.

[0025] The lower clamp 4 and the wire pressing plate 5 are fastened with screw 2. The design of the wire pressing plate 5 is to ensure that the wire harness 12 is clamped between the lower clamp 4 and the wire pressing plate 5 to avoid crimping problems caused by wire harness shaking during the crimping process.

[0026] When the utility model is in operation, the insulation of the wire harness of the required crimped terminal is stripped to ensure that the wire of the crimped part is exposed; the matching upper clamp 3 and lower clamp 4 are selected according to the terminals, and the upper clamp 3 and lower clamp 4 are installed at the corresponding positions; the terminals 13 are sequentially placed in the contoured grooves on the lower surface of the lower clamp 4, the wire harness 12 is placed in the wire harness groove, and the part of the wire harness 12 with the stripped insulation is placed in the terminal 13, and the wire pressing plate 5 is installed to fix the wire harness; the crimping of the terminal can be completed by pressing the head of the pressing handle 1; if there is a need to control the crimping force, the operator can stand on the back of the tooling and read the pressure value through the pressure gauge 11. When the value of the pressure gauge 11 reaches the recommended pressure range of the terminal, it is sufficient; after the terminal is crimped, the pressing handle 1 is released, the wire pressing plate 5 is removed, and the crimped wire harness is taken out.

[0027] The utility model is designed with a wire harness terminal crimping tool, which can realize the simultaneous crimping of multiple wire harnesses, thereby improving the crimping efficiency; the lever-type pressing handle facilitates the control of the crimping force, ensures the crimping quality and stability, reduces the overall time consumption of the bottleneck step in wire harness production, and improves the overall efficiency of wire harness production.
