Description

Technical Field

[0001] The utility model belongs to the technical field of memory chip testing, and particularly belongs to a board card plugging device. Background Art

[0002] In the field of memory chip testing, the common hardware stacking method in a memory chip tester is that two board cards are connected perpendicular to each other, and the two board cards are usually connected by a connector. The insertion and extraction force of such a connector is very large, and it is difficult to insert and extract.

[0003] Currently, there are usually two methods for inserting and extracting two board cards. The first is mainly manual operation, which is laborious and time-consuming. The second is to use auxiliary tools. Common board card extractors can only achieve one of the functions of extracting or inserting the board, and they are relatively large in size, occupying space. Moreover, in the case of a large insertion and extraction force of the connector, these common extractors are often insufficient in strength, and the pins of the connector are usually relatively fine, and it is easy to cause deformation or fracture of the connector pins during the insertion and extraction process, which will affect the signal connection at least and cause damage to the connector at worst.

[0019] Please refer to Figure 1 As shown, a board card plugging and unplugging device provided in this embodiment includes a first board card assembly 1 and a second board card assembly 2. The middle parts of the first board card assembly 1 and the second board card assembly 2 are electrically connected through a connector 3, and both sides of the first board card assembly 1 and the second board card assembly 2 are detachably connected through a connection assembly;

[0020] The connection assembly includes a pry bar 8 and a force-receiving plate 10. The pry bars 8 are rotatably arranged on both sides of the second board card assembly 2 respectively. One end of the pry bar 8 is a tiger mouth end, and the other end of the pry bar 8 is a handle end. The force-receiving plates 10 are arranged on both sides of the first board card assembly 1 respectively. The tiger mouth end of each pry bar 8 cooperates with the corresponding force-receiving plate 10; Rotating shaft seats 9 are arranged on both sides of the second board card assembly 2 respectively. A rotating shaft is arranged on the rotating shaft seat 9, and the tiger mouth end of the pry bar 8 is rotatably connected to the rotating shaft.

[0021] In the above embodiment, as Figure 1The figure shows a schematic connection structure of the first board card assembly 1 and the second board card assembly 2 of the utility model. The first board card assembly 1 is below and the second board card assembly 2 is above. The middle parts of the first board card assembly 1 and the second board card assembly 2 are electrically connected through a connector 3, and the two sides are structurally connected through a connection assembly. Specifically, the first board card assembly 1 includes a board card fixing support plate, which is used to support and fix the board card and strengthen the function of the board card, protecting the board card from deformation and damage during plugging and unplugging. A slot is opened in the middle of the board card fixing support plate, and a board card and a connector 3 (male or female socket) are arranged in the slot. The connector 3 is used for signal transmission and function realization after the two board cards are plugged. Force-receiving plates 10 are respectively arranged on both sides of the slot, and the side surface of the force-receiving plate 10 is above the slot. Correspondingly, the second board card assembly 2 includes a board card plugging and unplugging support plate, which is used to support and fix the board card and strengthen the function of the board card, protecting the board card from deformation and damage during plugging and unplugging. A board card and a connector 3 are arranged in the middle of the board card plugging and unplugging support plate, and this connector 3 is cooperatively connected with the connector 3 of the first board card assembly 1 below (male or female socket). Rotating shaft seats 9 are arranged on both side surfaces of the board card plugging and unplugging support plate. A rotating shaft is provided on the rotating shaft seat 9, and a lever 8 is rotatably connected to the rotating shaft. The lever 8 is in the shape of a wrench. One end of the lever 8 is a tiger mouth end, which cooperates with the force-receiving plate 10 during disassembly and assembly. The tiger mouth end has a hole, which is connected to the rotating shaft to form a rotation fulcrum. The other end is a pulling hand end, that is, a force application end, for manual operation;

[0022] When the first board card assembly 1 and the second board card assembly 2 are assembled, when the connectors 3 of the two are plugged, manually pull up the pulling hand ends of the levers 8 on both sides so that the tiger mouth ends of the levers 8 catch the force-receiving plates 10 on both sides, then press down while holding the pulling hand ends, so that the second board card assembly 2 is reversely stressed to make the connectors 3 of the two tightly plugged. When the lever 8 is parallel to the board card fixing support plate, the plugging is in place. When it is necessary to change the type or perform maintenance and the first board card assembly 1 and the second board card assembly 2 need to be disassembled, similarly, the tiger mouth ends of the levers 8 on both sides are made to catch the force-receiving plates 10, and at the same time, pull up the pulling hand ends of the levers 8 and apply force upward. The lever 8 rotates, prying the connector 3 of the second board card assembly 2 apart, and then the second board card assembly 2 can be easily removed. Therefore, during the entire disassembly and assembly process, no external tools are needed and only manual operation is required, and the accurate positioning and disassembly and assembly of the board cards can be achieved without much effort. At the same time, the safety of the board cards is protected, which greatly facilitates the operation and maintenance between the board cards.

[0023] In an alternative solution of the above embodiment, the connection assembly includes a guide rod 4 and a positioning block 5. The guide rods 4 are respectively arranged on both sides of the second board card assembly 2, the positioning blocks 5 are respectively arranged on both sides of the first board card assembly 1, a positioning hole is arranged on each positioning block 5, and the guide rod 4 is connected to the corresponding positioning hole;

[0024] The connection component includes a hand-tightening bolt 6 and a locking screw hole 7. The hand-tightening bolts 6 are respectively arranged on both sides of the second board card component 2, and the locking screw holes 7 are respectively arranged on both sides of the first board card component 1. The hand-tightening bolt 6 is connected to the corresponding locking screw hole 7.

[0025] In this alternative solution, the connection component further includes a guide rod 4 and a positioning block 5. The guide rods 4 are installed on both sides of the second board card component 2. Correspondingly, the positioning blocks 5 are installed on both sides of the first board card component 1. The positioning blocks 5 have positioning holes. The guide rods 4 and the positioning blocks 5 are used for positioning and guiding when the first board card component 1 and the second board card component 2 are inserted and removed, so that the two board card components can be accurately inserted and removed in place. At the same time, the connection component further includes a hand-tightening bolt 6 and a locking screw hole 7. The hand-tightening bolts 6 are installed on both sides of the second board card component 2. Correspondingly, the locking screw holes 7 are installed on both sides of the first board card component 1. The hand-tightening bolt 6 and the locking screw hole 7 are used to lock the first board card component 1 and the second board card component 2 together after they are inserted in place to prevent loosening.

[0026] During installation, first align the two wire rods on the second board card component 2 with the positioning holes on both sides of the first board card component 1, so that the second board card component 2 can slide down along the holes. When it reaches the plug-in position of the connectors 3 of the two components, manually pull up the handle ends of the two-sided assist lever 8. The tiger mouth end of the lever 8 catches the stress plates 10 on both sides, hold down the handle end and press down. The second board card component 2 is reversely stressed to make the connectors 3 of the two components tightly plugged. When the lever 8 is parallel to the board card fixed support plate, the plugging is in place. Tighten the hand-tightening bolts on both sides to ensure that the two board card components do not loosen.

[0027] However, when the board card needs to be replaced or maintained, first manually unscrew the hand-tightening bolts 6 on both sides, let the tiger mouth ends of the two-sided levers 8 catch the stress plates 10, and at the same time pull up the handle ends of the levers 8 and apply force upward. The lever 8 rotates to pry the connectors 3 of the second board card component 2 apart, and then the second board card component 2 can be taken out upward along the guide rod 4.
