Improper use of crimp terminals often leads to uncontrollable dangers in mechanical equipment. With the rapid development of the electronics industry, the use of crimp terminals has become wider and wider, with more and more types, and the models of the same type of crimp terminals have also increased. Therefore, it is very important to inspect the model of crimp terminals (including size and character information) and use crimp terminals that meet the requirements.

These all belong to the protection scope of the present invention.

[0046] like Figure 1 As shown, a combined inspection tool for multiple types of aerospace crimping terminals provided by the present invention includes a base 1, a mandrel mounting plate 3, and a size mandrel 4. The mandrel mounting plate 3 is detachably arranged on the base 1, and the size mandrel 4 is accommodated in the mandrel mounting plate 3. The size mandrel 4 matches the crimping terminal 5. The size mandrel 4 includes a plurality of size mandrels 4 with different diameters, and the plurality of size mandrels 4 are respectively accommodated in the mandrel mounting plate 3.

[0047] The combined inspection tool of the present invention adopts mandrels 4 of different sizes to match the size of crimping terminals 5, and can realize rapid inspection of multiple and various types of aerospace crimping terminals 5, and simultaneously realize inspection of multiple different sizes of aerospace crimping terminals 5. The outer dimensions of the base 1 and the mandrel mounting plate 3 are scientifically designed and easy to move. When the paired products are inspected with both hands, the outer dimensions of the inspection tool meet the working range of the microscope, and meet the requirements of carrying out efficient inspection of the character information on the surface of the metal crimping terminal 5 and the size of the crimping terminal 5 body.

[0048] Specifically, Figure 2 and Figure 3 As shown, the structural dimensions of the base 1 are obtained by mechanical processing, which meets the requirements of the combined inspection tool for increased weight, stable center of gravity, anti-swaying and easy movement. The base 1 is preferably made of PE (polyethylene) material, which is lightweight and highly wear-resistant. It is preferably a PE flat plate with a certain thickness. The length of the flat plate is greater than the length of the mandrel mounting plate 3, and the width of the flat plate is greater than the width of the mandrel mounting plate 3, which is convenient for placing and moving the inspection tool. The mandrel mounting plate 3 is detachably arranged on the base 1. A feasible implementation method is: the base 1 and the mandrel mounting plate 3 are directly bonded together by double-sided tape 2. The double-sided tape 2 can be purchased from the market at a comparative price. The bonding force of the double-sided tape 2 meets the need for mechanical processing and connection with fasteners. The mandrel mounting plate 3 can be quickly and effectively connected to the base 1, and the disassembly and assembly are convenient. The base 1 and the mandrel mounting plate 3 are reliably bonded together by the bonding force of the double-sided tape 2, so that quick disassembly and assembly maintenance can be achieved.

[0049] Specifically, Figure 3 and Figure 4 As shown, the mandrel mounting plate 3 is made of PE (polyethylene) material, which is lightweight and highly wear-resistant. The length, width, and height of the mandrel mounting plate 3 are scientifically designed and obtained through mechanical processing. When the product is held in a fist state with both hands, it can be within the working range of the microscope and meet the needs of efficiently inspecting the character information on the surface of the metal crimping terminal 5. The mandrel mounting plate 3 includes a plurality of mandrel mounting holes 301, and any mandrel mounting hole 301 corresponds to accommodating a mandrel 4 of any size. An expansion joint 302 is provided at the mandrel mounting hole 301, and the longitudinal direction of the expansion joint 302 is parallel to the axial direction of the mandrel mounting hole 301; the expansion joint 302 penetrates the mandrel mounting plate 3 in the longitudinal direction, and the expansion joint 302 extends from the mandrel mounting hole 301 to the outside of the mandrel mounting plate 3 in the transverse direction. The expansion joint 302 processed at the mandrel mounting hole 301 on the mandrel mounting plate 3 can directly plug and unplug mandrels 4 of various sizes without the aid of tools. One arrangement of the mandrel mounting holes 301 is that the mandrel mounting holes 301 are arranged in two rows in a one-to-one correspondence on the mandrel mounting plate 3 .

[0050] Specifically, the size mandrel 4 is preferably made of stainless steel, which is not easy to produce excess material and has high strength and corrosion resistance.

Chamfers 403 are provided at the large diameter end 401 and the small diameter end 402. The large diameter end 401 of each size mandrel 4 is machined to obtain a uniform outer diameter size, good interchangeability, and suitable for free combination between different crimping terminals 5. The small diameter end 402 is machined to obtain an outer diameter size and chamfer 403 matching the size of the crimping terminal 5 according to the model requirements. The chamfer 403 has a guiding function, which facilitates quick centering and alignment when the crimping terminal 5 is placed.

[0051] The core shaft mounting plate 3 of the present invention is bonded to the base 1 by double-sided tape 2. The expansion joint 302 arranged in the core shaft mounting hole 301 on the core shaft mounting plate 3 has a certain friction damping, which is convenient for installing core shafts 4 of various sizes and meets the requirement that core shafts 4 of various sizes can be directly installed on the core shaft mounting plate 3 in a plug-in manner without the need for auxiliary tools.
