In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0017] See also Figure 1 , 2 , 3, and 4 are schematic diagrams of preferred embodiments of the present invention. The present invention is related to a protective shell for a lead assembly production process, the protective shell having a bottom plate 1 and a peripheral wall portion 2 extending upward from the bottom plate, the peripheral wall portion 2 extending upward from the three sides of the bottom plate, so that the protective shell forms a drawer shape with side openings. An upward supporting surface 11 is provided inside the bottom plate 1, the supporting surface 11 is used to support the lower side of the lead assembly 3, and the wires of the lead assembly 3 extend out of the protective shell from the corresponding opening to reduce interference. In this embodiment, the supporting surface 11 is a step surface that matches the shape of the lower side of the lead assembly 3, so as to obtain effective positioning and avoidance, and increase the stability and positioning effect of the placement of the lead assembly 3. A fixing groove 21 is provided on the corresponding side wall of the peripheral wall portion 2, and the fixing groove 21 is used to position a first positioning portion 31 preset on the left side of the lead assembly 3. The shape and size of the fixing groove 21 match the first positioning portion 31, and can provide positioning and limiting; and a second positioning portion 32 is provided on the right side of the lead assembly 3, and the second positioning portion 32 is limited by the buckle 4, so that the lead assembly 3 is in a stable posture after being placed in the protective shell; the buckle 4 is embedded in the peripheral wall portion 2 and can expand and contract relative to the peripheral wall portion 2, so that the buckle 4 can be retracted to fix the lead assembly 3.

At the same time, the first positioning portion 31 and the second positioning portion 32 are arranged symmetrically, and correspondingly, the fixed slot 21 and the buckle 4 are arranged to be opposite to each other on the left and right, and the inner side of the buckle 4 is provided with a corresponding snap-in slot 41, and the shape and size of the snap-in slot 41 are consistent with the fixed slot 21. When in use, first install the first positioning portion 31 on the left side of the lead assembly 3 into the fixed slot 21, and insert it obliquely, and then press the lead assembly 3 right into the buckle 4, and use the expansion and contraction of the buckle 4 to press the lead assembly 3 right into the buckle 4, and at the same time, the second positioning portion 32 is locked and restricted by the snap-in slot 41 of the buckle 4, so that the lead assembly 3 is fixed in the protective shell, so that the lead assembly 3 is integrated with the protective shell, and the lead assembly 3 is not easy to move, so that the PIN pin can be prevented from being compressed and deformed, and the production process can be protected. When disassembling, the buckle 4 is pulled to separate the clamping groove 41 from the second positioning portion 32, and the lead assembly 3 can be taken out from the protective shell, which is easy to operate.

[0019] Figure 1 , 2As shown in Figures 3 and 4, in this embodiment, the buckle 4 is integrally formed with the peripheral wall 2 and the bottom plate 1 using a plastic material. The buckle 4 has a root and a column 42 extending upward from the root. A snap-in groove 41 is arranged on the inner side of the column 42, and an outward-flashing pull portion 43 is provided at the top of the column 42 to facilitate manual operation of the buckle 4. The root of the buckle 4 is connected to the peripheral wall 2, and a bending portion 44 is provided on the outer side of the root. A spacing groove 5 is provided between the column 42 and the peripheral wall 2, and the column 42 can expand and contract with the bending portion 44 as a fulcrum. The spacing groove 5 provides an escape space to meet the buckle activity. The bending portion 44 is a local appropriate cutting of the root, such as thinning or forming a groove, etc., to obtain an elastic bending function to facilitate the activity of the column 42.
