Example one

Referring to fig. 1 to 7, the magnetic concentrator for crimping a wire harness according to the present embodiment includes a magnetic concentrator main body 100, which may be made of a copper alloy material or a chromium zirconium copper material having high strength, high conductivity, or the like according to actual conditions; meanwhile, the magnetism collecting body 100 adopts a split structure, that is: the magnetic collection main body 100 is formed by splicing at least two magnetic collection lobes, and the overall structure of the spliced magnetic collection main body 100 can be a cylindrical structure, a plate-shaped structure or other geometric shapes; meanwhile, the magnetic collection body 100 formed by splicing has a crimping action hole 110, a coil placing hole 120 and a flow guide seam 130; the following are described separately.

Referring to fig. 1 to 3, the pressing hole 110 is mainly used for providing an assembling or accommodating space for a to-be-pressed portion of a wire harness to be pressed, and is disposed through the magnetic collecting body 100 along the first direction, so that the pressing hole 110 can naturally form two opposite end portions, one of which is defined as a first end portion 110a and the other as a second end portion 110 b; when the magnetic collector is applied, one end of a wire harness cable A of a wire harness to be crimped is inserted into the crimping action hole 110 through the first end 110a, an end sleeve of a wire harness terminal B of the wire harness to be crimped is inserted into the crimping action hole 110 through the second end 110B, and the end sleeve of the wire harness terminal B is sleeved on the wire harness cable A. Meanwhile, the crimping action hole 110 is formed in the splicing surfaces of the two adjacent magnetic collecting lobes, and it can also be understood that the crimping action hole 110 is formed by enclosing the splicing surfaces of the two adjacent magnetic collecting lobes, specifically, a groove structure extending along the first direction is formed in the splicing surfaces of the magnetic collecting lobes, when the splicing surfaces of every two magnetic collecting lobes are overlapped, the groove structure can be used for enclosing to form the crimping action hole 110, so that by disassembling the magnetic collecting lobes, the part to be crimped of the wire harness to be crimped can be quickly placed in the groove structure corresponding to the crimping action hole 110 or the wire harness subjected to crimping treatment can be taken out of the magnetic collector.

It should be noted that the term "first direction" used herein is defined in terms of a direction defined by referring to the axial direction of the crimp applying hole 110 and the axial direction of the coil placing hole 120, and it is also understood that the first direction is a direction parallel to the axial direction of the crimp applying hole 110 and/or the axial direction of the coil placing hole 120.

Referring to fig. 1 to 3, the coil placing hole 120 is mainly used for providing a placing or accommodating space for the discharge coil 200, so that the discharge coil 200 and the magnetism collecting core 100 are assembled when the magnetism collector is applied; the coil placement hole 120 is provided through the magnetism collecting body 100 in the first direction, that is, the coil placement hole 120 and the pressure-bonding hole 110 are parallel to each other; wherein two or more crimping holes 110 are distributed around the circumference of the coil placement hole 120.

The magnet collector for wire harness crimping as claimed in claim 7, wherein said first end portion and said second end portion are each of a tapered hole structure, said bus bar hole portion is of a straight hole structure, and both ends of said bus bar hole portion are coaxially communicated with a tapered tip of said first end portion and a tapered tip of said second end portion, respectively.

9. A wire harness crimping and forming device for crimping a wire harness terminal to a wire harness cable, comprising:

a magnetic collector for collecting a magnetic field and applying the collected magnetic field to a harness terminal so that the harness terminal is crimped to a harness cable, the magnetic collector employing the magnetic collector for harness crimping as claimed in any one of claims 1 to 8, the harness terminal and a portion to be crimped of the harness cable being located at a crimping action hole;

a discharge control member for discharging the discharge coil to form a pulsed excitation current within the discharge coil to generate a magnetic field; the discharge control member is electrically connected with the discharge coil.

10. The wire harness crimp forming device of claim 9, wherein the discharge control member includes a capacitor module, a power module and a control module, the power module and the capacitor module being electrically connected to the control module, respectively, and the discharge coil being electrically connected to the capacitor module, the control module being configured to control the power module to charge the capacitor module and to control the capacitor module to discharge the discharge coil.
