Description

Technical Field

[0001] This utility model relates to the field of wire harness crimping technology, specifically to a crimping device for coaxial wire harness processing. Background Technology

[0002] With the rapid development of electric vehicles, related industries are seeking to supply sufficient quantities of high-quality, cost-effective components, especially in the use of wiring harnesses, which are increasingly being used in automobiles. Existing shielded cables are constructed by inserting the outer sheath of the wire into an inner shielding ring, then folding the shielding wire back over the inner shielding ring, finally inserting the outer shielding ring, and then crimping it using a crimping tool. In large-scale production, fixed equipment can be used for batch crimping of wiring harnesses. However, it has been found that when repairing the wiring harness shielding ring after vehicle production, some wiring harnesses are quite long. Disassembling the entire harness and then crimping it using fixed tools would be labor-intensive and difficult. Therefore, this improved technical solution is proposed. Utility Model Content

[0003] The purpose of this invention is to overcome the inflexibility of the crimping tools for shielding rings in the prior art, and to provide a crimping device for coaxial cable processing.

[0004] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a crimping device for coaxial cable harness processing, comprising a clamp body, the clamp body including a first handle and a second handle, a support head hinged to the upper part of the first handle and the second handle, a bent portion provided inwardly at the top of the first handle and the second handle and hinged through a connecting shaft, a support frame provided above the support head, a crimping structure for crimping the cable harness provided above the connecting shaft, the crimping structure including a lower pressing block provided at the lower part of the support frame, an upper pressing block provided at the upper part of the support frame, and a crimping groove provided on the opposing surfaces between the lower pressing block and the upper pressing block.

[0005] Furthermore, the bottom of the support frame is connected to the support head, a limit plate is provided on the outer side of the support frame, and a limit groove is provided in the middle of the limit plate to limit the movement range of the connecting shaft.

[0006] Furthermore, the support frame is composed of two plates arranged opposite to each other, the upper pressure block has an ear plate connected to the support frame on its side, and the lower pressure block has its side slidably disposed inside the support frame.

[0007] Furthermore, a cutter is provided on the rear end face of the upper pressure block, and a support block is provided below the cutter.

[0008] Furthermore, the support block is connected to the lower pressure block, and the support block is provided with a receiving groove in the axial direction, which is connected to the pressing groove.

[0009] Furthermore, the support block is provided with a cutting groove in the width direction for accommodating the lower part of the cutter, and the cutting groove intersects with the receiving groove.

[0010] The beneficial effects of this utility model embodiment are as follows: by squeezing the first handle and the second handle, the lower pressure block moves upward to complete the crimping action. After the crimping is completed, the wire harness can be trimmed with a cutter, thus completing the entire repair process. When repairing a wire harness end in a car, the process of completely removing the wire harness is eliminated, making it convenient for on-site use. The structure is compact and the operation is simple. It is particularly suitable for vehicle after-sales repair, which can significantly improve repair efficiency and reduce the difficulty of operation. Attached Figure Description

[0015] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0016] See Figures 1 to 3 This utility model discloses a crimping device for coaxial cable processing, mainly composed of a clamp body. The clamp body includes a first handle 101 and a second handle 102, which are linked by a support head 103 hinged at the top. The tops of the first handle 101 and the second handle 102 are bent inward and hinged by a connecting shaft 1 to ensure the flexibility and stability of the handles during operation. A spring is provided between the first handle 101 and the second handle 102 to keep them in an open state. A support frame 2 is provided on the upper part of the support head 103, which serves as the main load-bearing component of the crimping structure and also provides guidance during the crimping process to facilitate positioning and ensure processing effect.

[0017] The crimping structure is located above the connecting shaft 1 and includes a lower pressing block 201 located at the lower part of the support frame 2 and an upper pressing block 202 located at the upper part of the support frame 2. Both the lower pressing block 201 and the upper pressing block 202 have crimping grooves 203 on their opposite surfaces for precisely crimping the wire harness shielding ring. During operation, by squeezing the first handle 101 and the second handle 102, the lower pressing block 201 moves upward and cooperates with the upper pressing block 202 to complete the crimping action and complete the crimping of the shielding layer. To ensure the accuracy of the crimping process, the bottom of the support frame 2 is tightly connected to the support head 103. At the same time, a limit plate 104 is provided on the outer side of the support frame 2. A limit groove is opened in the middle of the limit plate 104 to limit the movement range of the connecting shaft 1, thereby preventing offset or misalignment during the crimping process and ensuring the crimping quality.

[0018] The support frame 2 consists of two opposing plates, providing a stable structure that is easy to install and maintain. Different sizes of upper pressure block 202 and lower pressure block 201 can be replaced to meet various usage requirements. The upper pressure block 202 has ear plates on its side that connect to the support frame 2. The fixed connection between the ear plates and the support frame 2 ensures the stability of the upper pressure block 202 during the crimping process. The lower pressure block 201 is slidably positioned inside the support frame 2, facilitating adjustment of the crimping position according to the wire harness specifications and improving the device's versatility. This also ensures the stability of the lower pressure block 201's sliding direction, guaranteeing a satisfactory crimping effect.

[0019] To further enhance the functionality of the device, a cutter 3 is provided on the rear end face of the upper pressure block 202 for trimming the wire harness when necessary. A support block 301 is provided below the cutter 3, connected to the lower pressure block 201 to ensure the stability of the wire harness during cutting. A receiving groove is provided along the axial direction of the support block 301, communicating with the crimping groove 203 for easy positioning and fixing of the wire harness. A cutting groove is provided along the width direction of the support block 301, intersecting with the receiving groove, providing a cutting channel for the cutter 3 and ensuring smooth cutting. In actual operation… Repair personnel only need to place the wire harness shielding ring into the crimping groove 203 of the lower pressure block 201, and press the first handle 101 and the second handle 102 to make the lower pressure block 201 move upward to complete the crimping action. After crimping, the wire harness can be trimmed with the cutter 3 to complete the entire repair process. When repairing a wire harness end in a car, the process of completely removing the wire harness is eliminated, which is convenient for on-site use. The structure is compact and easy to operate, making it particularly suitable for vehicle after-sales repair. It can significantly improve repair efficiency and reduce the difficulty of operation.
