[0015] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

[0016] It should be noted that, in the description of the present invention, terms such as "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0017] See also Figure 1 , 2, 3, 4, and 5 are schematic diagrams of preferred embodiments of the present invention. The present invention is related to a protective shell suitable for the production process of a lead assembly, which has a base 1 and an upper cover 2 that can be molded relatively, the base 1 and the upper cover 2 are plastic parts, the lead assembly 3 has a main body 31 and an extended wire 32, and the main body 31 has a PIN pin. The base 1 is provided with a mounting groove 11 with an upward opening, and a hanging platform 12 and a tooth groove 13 extending from the mounting groove 11 are provided on the front side of the mounting groove 11. The shape and size of the mounting groove 11 match the main body 31 of the lead assembly 3, and a limiting portion 14 is provided inside the mounting groove 11. The main body 31 of the lead assembly 3 is placed in the mounting groove 11 and the displacement of the main body 31 in the front and rear directions is limited by the limiting portion 14. The extended wire 32 of the lead assembly 3 extends from the tooth groove 13, and the number of the tooth grooves 13 is consistent with the number of the extended wires 32, so that the entire row of extended wires 32 can be placed separately. The rear side of the upper cover 2 is connected to the corresponding side of the base 1 through a hinge structure to form an openable and closable system, which is convenient for installing and removing the lead assembly 3. A movable buckle 21 is provided on the front side of the upper cover 2, and the buckle 21 is engaged with the hanging platform 12, so that the upper cover 2 and the base 1 are in a covered state and will not separate, so that the protective shell can stably wrap the lead assembly 3 to achieve protection of the production process. The upper cover 2 covers the opening of the installation groove 11, and a positioning tooth 22 is also provided on the corresponding side of the upper cover 2. The positioning tooth 22 cooperates with the tooth groove 13 to clamp the protruding wire 32 of the lead assembly 3, further restricting it, so that the combination of the protective shell and the lead assembly 3 is more stable.

[0018] In this embodiment, the base 1 and the upper cover 2 are both plastic parts, preferably made in one piece, but it is not excluded that they are made in parts and then assembled together, which has a simple structure, is easy to manufacture, and has low cost. The limiting part 14 is a vertical rib protruding on the inner wall of the mounting groove 11, forming a stop shoulder, and the limiting part 14 has two matching front and rear parts, which respectively limit the front and rear sides of the main body 31; the inner lower side of the upper cover 2 is provided with a downwardly protruding pressing part 23, which is used to limit the upper side of the main body 31. As shown in the figure, the pressing portion 23 is just located above the area between the two limiting portions 14. When working, the main body 31 of the lead assembly 3 is placed in the mounting groove 11 from top to bottom, and the inner bottom of the mounting groove 11 supports the lower side of the main body 31. The left and right sides of the main body 31 are limited by the corresponding inner side walls of the mounting groove 11, and the two limiting portions 14 correspond to the front and rear ends of the corresponding glue positions of the main body 31. After the upper cover 2 is closed, the pressing portion 23 limits the upper side of the main body 31, so that the main body 31 is restricted in all directions, so that the main body 31 of the lead assembly 3 is relatively stable in the protective shell and not easy to move, which can prevent the PIN needle from being compressed and deformed.

[0019] In this embodiment, the buckle 21 is a rubber position extending from the upper cover 2 and having a certain elasticity, and the one-piece structure is easy to manufacture. The buckle 21 is provided with an inner convex hook head 211 and a hand-held portion 212 located at the end of the extension, and the inner convex hook head 211 is engaged with the hanging platform 12. When in use, after the upper cover 2 is closed, the buckle 21 is pressed down with force to achieve the engagement of the inner convex hook head 211 with the hanging platform 12, so that the upper cover 2 and the base 1 are in a closed state and will not separate. When it is necessary to open, the hand-held portion 212 is pulled outward with force to separate the inner convex hook head 211 from the hanging platform 12, so that the upper cover 2 can be opened and the lead assembly 3 can be taken in and put out. In this embodiment, there are two buckles 21, and there are also two corresponding hanging platforms 12, which are respectively arranged at the left and right side ends of the tooth groove 13, symmetrically hung, and the stability of the upper cover 2 is increased. The upper cover 2 of this embodiment is also provided with a window hole 24 that passes through the upper and lower sides. The window hole 24 faces the main body 31 of the lead assembly 3. The internal situation can be observed through the window hole 24, and the processability can be increased, which is beneficial to the subsequent production process.

[0020] The protective shell provided by the utility model has a base and an upper cover that can be relatively molded, the base and the upper cover are plastic parts, which meet the requirements of the main body placement of the lead assembly and the extension of the external wires, and the upper cover and the base form an opening and closing system, which is convenient to use; the protective shell can greatly reduce the pressure damage to the product during the production process, and is portable, movable and placed, with low manufacturing cost, and can be repeatedly recycled, with better economy.
