Description

Technical Field

[0001] The utility model relates to the technical field of electronic module debugging and maintenance, in particular to an assisting plugging device for non-standard electronic modules. Background Art

[0002] At present, some signal processing electronic modules have been widely used in many special industries such as aviation and aerospace. Many application scenarios have put forward higher requirements for the size and weight of highly integrated electronic modules. Some electronic modules have cancelled the assisting extraction device and guide rail structure required by the standard specification, aiming to make the same highly integrated electronic module extremely miniaturized and improve the signal processing performance of the system.

[0003] In the prior art, there are two common forms of electronic modules: one is with an assisting extraction device and a guide rail structure, and the other is without an assisting extraction device and a guide rail structure. Although the electronic module with an assisting extraction device and a guide rail structure can ensure the integrity of the operator during debugging and maintenance, the size and weight of the whole system are greatly increased, and it cannot be applied to the scenarios with extremely strict requirements for size and weight. The electronic module without an assisting extraction device and a guide rail structure simplifies the structure of the electronic module carrier and further compresses the size and weight of the whole system, but it also loses the ability of plugging and guiding. When the operator debugs and maintains the electronic module, general tools are usually used to perform operations such as prying, topping, and pushing on it, which are extremely easy to damage the structural body and components of the electronic module. Even operators with strong technical capabilities cannot guarantee a high success rate of operation, resulting in abnormal signal processing functions of the electronic module. In severe cases, the whole system may not be able to work properly, greatly increasing the debugging and maintenance costs of the system. Summary of the Utility Model

[0045] In the present utility model, the number of the plug-assisting devices 2 can be set according to the specific model requirements of the cold-conduction plug-in of the non-standard signal processing module. For example, if there are a total of 8 groups of the plug-assisting devices 2, then it can support the plugging and unplugging operations of up to 8-slot modules at most. The external dimensions are 448mm×264mm×285.6mm, the working temperature is -20°C to 40°C, and the storage temperature is -40°C to 70°C. If there are a total of 9 groups of the plug-assisting devices 2, then it can support the plugging and unplugging operations of up to 9-slot modules at most. The external dimensions are 448mm×264mm×311mm, the working temperature is -20°C to 40°C, and the storage temperature is -40°C to 70°C. If there are a total of 10 groups of the plug-assisting devices 2, then it can support the plugging and unplugging operations of up to 10-slot modules at most. The external dimensions are 448mm×264mm×336.4mm, the working temperature is -20°C to 40°C, and the storage temperature is -40°C to 70°C.

[0046] The main body of the tooling of the present utility model is made of aluminum material, which is light in weight. The plug-assisting device 2 is made of stainless steel material, which is wear-resistant and does not corrode after long-term use.

[0047] The specific working principle of the present utility model is as follows:

[0048] I. Installation:

[0049] Rotate all the plug-assisting devices 2 on the tooling out of the installation groove 14 around the damping pin shaft 22 through the connecting rod 23, and the tooling is in a state where it can be installed.

[0050] Before installing the non-standard signal processing module, remove the interference components and place it face up on the table, and it is in a state where it can be docked with the tooling.

[0051] Align the tooling with the signal processing module, and ensure that the lower guide rail 17, upper guide rail 18 of the tooling and the housing of the signal processing module are aligned. Let the tooling slide downwards and wrap the signal processing module;

[0052] After the contact surface between the tooling and the signal processing module is tightly attached, lock the connection bolts 16 of the cold conduction plug that do not need to be pulled out. The connection bolts 16 corresponding to the cold conduction plugs that need to be pulled out shall not be locked;

[0053] Flip the tooling by 90° and stand it upright on the desktop, then the pulling and pushing operations of the cold conduction plug can be carried out.

[0054] II. Disassembly:

[0055] Adjust the overall position and pose through the tooling. First, rotate the assistive pulling device 2 out of the installation groove 14 around the damping pin shaft 22 through the connecting rod 23, and then adjust the signal processing module to be placed upwards on the desktop;

[0056] Loosen all the connection bolts 16 fixed to the signal processing module, and take out the tooling along the guide rail.

[0057] III. Pulling:

[0058] After the tooling and the signal processing module are combined, rotate the milled flat surface of the switch chuck of the handle switch 213 of the assistive pulling device 2 to be horizontal with the notch of the U-shaped card slot 212 of the assistive pulling handle 211 to unlock the assistive pulling handle 211;

[0059] After the assistive pulling handle 211 is adjusted to one end of the sliding groove 25, rotate the assistive pulling handle 211 so that the assistive pulling roller 29 abuts against the groove on the side of the plug, and fold the connecting rod 23 back into the installation groove 14. At this time, the switch rod can enter the stepped hole 111 under the drive of the spring, and the connecting rod 23 can be fixed by connecting the connecting thread provided at the inner end of the switch rod with the threaded hole of the stepped hole 111;

[0060] Pull the assistive pulling handles 211 on both sides simultaneously with both hands to complete the pulling operation of the cold conduction plug, as Figure 7 shown.

[0061] IV. Pushing:

[0062] The pushing operation can be performed only after the cold conduction plug slides into the signal processing module until the connector is in normal contact;

[0063] After the assistive pulling handle 211 is adjusted to the other end of the sliding groove 25, rotate the assistive pulling handle 211 so that the assistive pulling roller 29 abuts against the outer surface of the plug, and fold the connecting rod 23 back into the installation groove 14. At this time, the switch rod can enter the stepped hole 111 under the drive of the spring, and the connecting rod 23 can be fixed by connecting the connecting thread provided at the inner end of the switch rod with the threaded hole of the stepped hole 111;

[0064] Press the two side assisting extraction handles 211 with both hands simultaneously to complete the pushing operation of the heat conduction plug-in, as Figure 8 shown.

[0065] When the utility model is used for debugging and maintenance operations of an electronic module, the assisting extraction device 2 can provide two opposite operations of extraction and pushing, and the assisting extraction rollers 29 on the assisting extraction handles 211 are used to provide rolling friction to replace the traditional sliding friction, effectively avoiding damage to the electronic module.

[0066] When the utility model is used for plugging an external sub-card or a cable into the electronic module, the connecting rod 23 can be rotated without affecting the electrical connection, and it is applicable to various debugging scenarios of the electronic module.

[0067] When the utility model is used for debugging and maintenance of the electronic module, a single person can operate it without the cooperation and assistance of others, and the work efficiency is increased by more than 2 times.

[0068] The above has made an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above methods. As long as various improvements are made by adopting the method concept and technical solution of the utility model, or directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
