Product details
37-pin plastic d-sub backshell: lightweight connection protection and cable management solution.
In the interconnection systems of modern electronic devices, d sub connector are widely used in industrial control, computer hardware, and communication equipment due to their robustness and durability. However, the protective features of the connectors themselves often fall short in dealing with complex field environments. In such situations, the D-Sub backshell becomes an indispensable accessory. Among these, the 37-pin plastic d connector backshell stands out for its lightweight design, high flexibility, and excellent overall performance, making it an ideal choice for engineers working in space-constrained or lightweight-requirement scenarios.
Core material and structural design.
The 37-pin plastic D-sub back cover is typically manufactured using high-performance engineering plastics (such as PC, polycarbonate, and other thermoplastic materials). Compared to traditional metal die-cast back covers, the primary advantage of plastic back covers is their extremely lightweight nature, which is particularly important in aerospace or portable devices where there are strict requirements regarding the overall weight of the equipment.
In terms of structural design, the plastic rear casing typically employs a single-piece snap-in mechanism or a double-piece assembly design, allowing for quick assembly around end-terminated connectors using the snap-in mechanism, without the need for complex tools, thereby significantly reducing installation time and labor costs. Additionally, the interior of the plastic rear casing generally provides ample space for termination, capable of easily accommodating 37-pin solder or crimp points, and offers various cable outlet angles (such as 180° straight out or 45°/90° angled out) to cater to the wiring needs within compact cabinets.
Shielding and protection capabilities.
In terms of mechanical protection, the plastic rear casing provides abrasion-resistant protection for the vulnerable connector end. Some models also feature strain relief structures or cable clamps integrated into the design. This not only prevents internal solder joints from detaching due to stretching or vibration but also maintains the cable’s organization, thereby enhancing the overall reliability of the equipment.
Application scenarios and selection considerations.
The 37-pin plastic D-sub back shell is widely used in IT equipment, data communication, medical devices, and general industrial automation. When selecting a product, engineers need to consider the following key factors comprehensively:
1. Operating Temperature: The working temperature range for the plastic rear casing typically ranges from –35°C to +120°C. It is essential to ensure that it can accommodate the ambient temperature conditions under which the device operates.
2. Shielding requirements: When devices are used in environments with strong electromagnetic interference, it is essential to select models with metallized shielding layers and verify that their attenuation specifications (e.g., >40 dB) meet the required standards.
3. Cable routing direction: Based on the space gaps behind the panel, choose between a straight routing path or a angled rear casing to prevent excessive bending of the cables.
4. Locking Mechanism: Verify that the fastening components provided for the rear casing (such as 4-40 UNC screws or sliding locks) are compatible with the connector panel.
