Description

Technical Field

[0001] This utility model belongs to the field of antistatic technology, specifically an antistatic storage box for sensitive components. Background Technology

[0002] Sensitive elements are components that can sensitively sense the measured variable and respond accordingly. Due to their tiny size and complex structure, sensitive elements are particularly sensitive to electrostatic discharge (ESD). ESD can cause various types of damage to these components, including physical damage, performance degradation, and reduced reliability. Currently, they are typically stored in anti-static (i.e., conductive) storage boxes during transportation and storage.

[0003] Most current antistatic storage boxes use a single conductive material, which can save on overall manufacturing costs, but static electricity elimination is not thorough. A small number of antistatic storage boxes also have a grounding plate glued on them to conduct excess static electricity. While these methods can improve the static electricity elimination effect, they require an additional bonding process during the manufacturing of antistatic storage boxes, which increases the overall manufacturing process and cost (the cost of applying the adhesive). Moreover, there is a possibility of the adhesive falling off after bonding.

[0004] In view of this, an anti-static storage box for sensitive components is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-static storage box for sensitive components in order to solve the problems mentioned above.

[0006] The technical solution adopted by this utility model is as follows: a sensitive element anti-static storage box, including a box body and a box cover, the box cover covering the box body and forming a closed storage space; the four corners of the bottom of the box body protrude to form a support base, and a grounding component is provided at the center of the support base. The bottom end face of the grounding component is on the same horizontal plane as the bottom end face of the support base. The grounding component is integrally formed with the support base in a mold as an insert. The grounding component is made of a metal material with good conductivity.

[0007] In a preferred embodiment, both the inner surfaces of the box body and the box lid are coated with an electromagnetic shielding layer.

[0008] In a preferred embodiment, the box body is further provided with a protective seat, the top surface of which is recessed downward to form a plurality of receiving cavities for accommodating sensitive elements.

[0009] In a preferred embodiment, the top of the grounding member extends into the storage space and abuts against the protective base.

[0010] In a preferred embodiment, the top edge of the box body protrudes outward to form an outer reinforcing rib, and the bottom of the outer reinforcing rib and the outer wall surface of the box body are provided with a plurality of reinforcing rib positions at circumferential intervals.

[0011] In a preferred embodiment, the upper surface of the outer reinforcing rib protrudes circumferentially to form a sealing rib position, and the bottom end face of the box cover is provided with a sealing part that is adapted to be inserted into the sealing rib position. The sealing part has a U-shaped cross-section, and the sealing part and the sealing rib position are inserted to form a labyrinth waterproof structure.

[0012] In a preferred embodiment, the lid and the body are connected by a hinge, and a latch is provided between the lid and the body to lock them together. A handle is also rotatably connected to the front end of the body.

[0013] In a preferred embodiment, both the lid and the body are made of conductive material.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. In this utility model, multiple grounding components for static electricity discharge are designed at the bottom of the box, which can improve the static electricity elimination effect. Secondly, the grounding component itself is integrally formed with the box as an insert, which will not add extra processes and manufacturing costs.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] Reference Figure 1 and Figure 2 An anti-static storage box for sensitive components includes a box body 200 and a lid 100. The lid 100 covers the box body 200, forming a closed storage space. Support bases 220 protrude from the four corners of the bottom of the box body 200. A grounding element 400 is centrally located on the support base 220, with its bottom surface flush with the bottom surface of the support base 220. The grounding element 400 is integrally molded with the support base 220 as an insert. The grounding element 400 is made of a highly conductive metal. Multiple grounding elements 400 are designed at the bottom of the box body to conduct static electricity. When placed on a surface, static electricity can be directly discharged, improving the static elimination effect. Furthermore, since the grounding element 400 is integrally molded with the box body 200 as an insert, it does not add extra processes or manufacturing costs. The integral molding structure also ensures the strength of the connection between the grounding element 400 and the box body 200, preventing detachment. Preferably, the grounding element 400 is made of copper.

[0022] Furthermore, both the inner surfaces of the box body 200 and the box cover 100 are coated with an electromagnetic shielding layer 300 to effectively shield electromagnetic radiation interference and ensure the normal operation of the instruments and equipment. The electromagnetic shielding layer 300 is preferably made of nickel-based electromagnetic shielding coating.

[0023] Furthermore, a protective base 500 is provided inside the housing 200. The top surface of the protective base 500 is recessed downward to form several receiving cavities 510 for accommodating sensitive elements. The top of the grounding member 400 extends into the storage space and abuts against the protective base 500. The protective base 500 is made of TPU material. TPU has better elasticity than ordinary polyurethane, and TPU products have excellent load-bearing capacity, impact resistance and shock absorption performance, which can protect sensitive elements very well.

[0024] Furthermore, the top edge of the box body 200 protrudes outward to form an outer reinforcing rib 240. Multiple reinforcing rib positions 230 are spaced circumferentially along the bottom of the outer reinforcing rib 240 and the outer wall surface of the box body 200. Of course, crisscrossing reinforcing ribs can also be provided on the box lid 100. The outer reinforcing ribs 240 and reinforcing rib positions 230 ensure the strength of the box body 200 itself, preventing deformation under stress during use. Additionally, a handle-like structure is formed between the protruding outer reinforcing rib 240 and the box body 200, facilitating the handling of the storage box by staff.

[0025] Furthermore, a sealing rib position 210 is formed by a circumferential protrusion on the upper surface of the outer reinforcing rib 240, and a sealing part 110 is provided on the bottom surface of the lid 100 along the circumferential direction to be adapted to and inserted into the sealing rib position 210. The sealing part 110 has a U-shaped cross-section, and the sealing part 110 and the sealing rib position 210 are inserted to form a labyrinth waterproof structure. A labyrinth sealing structure is designed between the box body 200 and the lid 100 to ensure the sealing performance after the box body 200 and the lid 100 are combined, which can achieve the IP67 protection level of the storage box. An additional sealing strip can also be provided inside the sealing part 110.

[0026] Furthermore, the lid 100 and the body 200 are connected by a hinge (not shown in the figure), and a latch 700 is provided between the lid 100 and the body 200 to lock the two together. A handle 600 is also rotatably connected to the front end of the body 200. The latch 700 is an existing and well-known technology, and its specific structure will not be described here.

[0027] Furthermore, both the lid 100 and the body 200 are made of conductive materials, and the lid 100 and the body 200 are preferably made of carbon-doped conductive plastic.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
