Wherein, the upper extraction tool is mainly composed of a shaft housing to assemble an upper bracket, a metal wrench and a damping ring into a whole. The lower extraction tool is essentially consisted of a shaft housing to assemble a lower bracket, a wrench and a damping ring into a whole. The upper and lower extraction tools are made of die-casting metal blocks and provided with a guide pole and a supporting shaft housing and can connect with panels and printed circuit boards. In addition, the metal wrench can be processed into various shapes with steel plate on demand. Large holes are arranged on the wrench to rotate freely around the shaft housing, preferentially cover the wrench handle with plastics and bring comforts during operation. The other side of the wrench handle is provided with a toothed groove to clamp a case rail as a pivot. The utility model is characterized in simple structure, practicality, reliability, easy realization and adaptability to various cases in the communication industry featuring rapid development and especially requirements for higher reliability of printed circuit board extraction in the cases in accordance with CPCI standard, hence showing great values to be applied and promoted.
Description
Technical field
The utility model relates to a kind of communication product printed circuit board driver-extractor.
Background technology
After last century, the CPCI standard was released in late nineteen eighties Europe, obtain rapid promotion and application in computer realm.Do not make an exception, in the communications industry of the technology that uses a computer in a large number, big communication company of several in the world families takes the lead in the CPCI standard application to communication field.Enter this century, along with the deep development of mechanics of communication research, each state finds that all the CPCI standard that is suitable for the computer realm structure applies to communications industry and appears out its fatal defective suddenly: printed circuit board rises and pulls out difficulty even rise sometimes and pull out inefficacy.
Be illustrated in figure 1 as by the cabinet 100 of CPCI standard design and whole 300 of printed circuit board satisfying the CPCI standard, Figure 2 shows that whole printed circuit board 300 having installed existing CPCI standard driver-extractor, whole printed circuit board 300 is by metal decking 330, printed circuit board (pcb) 340, last driver-extractor 320, following driver-extractor 310 is formed, because last driver-extractor 320 and following driver-extractor 310 are symmetric arrangement, with the following driver-extractor shown in Fig. 3 a 310 is example, be by fixed block 3101, compound spanner 3102, straight pin 3103 grades are formed (shown in Fig. 3 b), compound spanner 3102 is again to combine (shown in Fig. 3 c) by plastic handle 3104 and kirsite claw 3105, thereby the A point is exactly that the most easy to wear having caused of spanner pulled out the inefficacy part among Fig. 3 a.
Therefore, the connector that the CPCI standard adopts in the prior art has not satisfied the demand of communications industry large information capacity high-speed transfer, the big capacity connector that adopts on the printed circuit board far away, make the pulling force square of original driver-extractor seem very inadequate, and operating difficulties.Having added and having pulled out the claw material is zinc die casting alloys, and the conference of exerting oneself surpasses the yield limit of material and damages, and pulls out inefficacy thereby caused.
Therefore wish to have a kind of printed circuit board driver-extractor, under the situation that printed circuit board and metal decking are not done to change, can replace the driver-extractor of original CPCI standard fully, can also increase pulling force square, convenient and strength-saving operation simultaneously.
The utility model content
Problem to be solved in the utility model has provided and a kind ofly both satisfied the CPCI standard-required and replace original driver-extractor fully, and is easy to operate again, and laborsaving reliable printed circuit board driver-extractor.
The technical scheme that the utility model adopted is: the printed circuit board driver-extractor comprises driver-extractor, following driver-extractor, last driver-extractor mainly by axle sleeve with upper bracket, plate work wrench, damping ring connects to form one whole, following driver-extractor mainly by axle sleeve with undersetting, plate work wrench, damping ring connects to form one whole, described upper bracket, undersetting is one can connect panel, printed circuit board also has lead and the die-cast metal piece of support sleeve, described plate work wrench can be by steel plate machine-shaping on demand, which is provided with macropore can be enclosed within on the axle sleeve and freely rotate, preferably pinch bar is wrapped up in plastics outward, to increase the comfort level of operation, the opposite side of pinch bar is processed with teeth groove, be used for blocking the cabinet crossbeam and pull out fulcrum as rising, described axle sleeve is preferably made with round steel, pass the plate work wrench riveting on bearing, effect is to support plate work wrench, guarantees that simultaneously plate work wrench freely rotates.
The ring system of damping described in such scheme metallic saucer washer, the centre is provided with macropore in order to wear axle sleeve.
The beneficial effects of the utility model are: because the printed circuit board driver-extractor is that upper and lower bearing, plate work wrench, axle sleeve and damping ring are become one whole by axle sleeve and each riveted joint of upper and lower bearing, therefore, satisfy the requirement of replacing fast fully, especially the utility model is that physical dimension according to the CPCI standard-required designs fully, for the equipment that has adopted CPCI standard printed circuit board driver-extractor, can be directly be connected and fixed with screw and PCB circuit board and metal decking, replace fast, fully and the physical dimension compatibility of CPCI standard.The employing of plate work wrench has also improved the reliability of operation greatly.The utility model is simple in structure, practical reliable, assembling rapidly, be easy to realize, applicability is strong, various cabinets especially adopt the more high reliability request of the cabinet of CPCI standard to printed circuit board plug proposition in the suitable current fast-developing communications industry, have good value for applications.
