Description

Technical Field

[0001] The utility model relates to the technical field of PCB board connection, in particular to a PCB board plugging and unplugging processing device. Background Art

[0002] PCB, also known as printed circuit board, is the provider of electrical connections for electronic components. It has a history of more than 100 years. Its design is mainly layout design. The main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, improves the level of automation and production labor rate. According to the number of layers of the circuit board, it can be divided into single-sided board, double-sided board, four-layer board, six-layer board and other multi-layer circuit boards. Because the graphics are repetitive and consistent, wiring and assembly errors are reduced, and equipment maintenance, debugging and inspection time are saved. The design can be standardized, which is conducive to interchangeability. It has high wiring density, small size and light weight, which is conducive to the miniaturization of electronic equipment, mechanized and automated production, and improves labor productivity and reduces the cost of electronic equipment.

[0003] In the existing PCB plug-in and pull-out devices, the connection structure commonly used in the PCB board is usually plug-in type, which can be quickly installed and removed during use, and the board body is convenient to use.

[0004] However, this plug-in device fixes the socket and the plug terminal by means of a limiting spring sheet. However, when the fixing of the socket and the plug terminal is cancelled, the limiting spring sheet cannot be controlled, thereby making it impossible to release the fixing of the socket and the plug terminal. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 As shown, the utility model is a PCB board plug-in and pull-out processing device, comprising a board body 1, a plurality of components 2 are arranged on the surface of the board body 1, a socket 3 is arranged on the surface of the board body 1, the socket 3 is electrically connected to the plurality of components 2, and the socket 3 is arranged on one side of the board body 1. The socket 3 is provided with an inner cavity, and the inner cavity of the socket 3 is provided with a plurality of contact pins 33, and the plurality of contact pins 33 are electrically connected to the components 2. Blocks 31 are arranged on the upper and lower sides of the inner cavity of the socket 3 near the outlet. The plurality of contact pins 33 are arranged on a mounting plate 36, and a plurality of second springs 37 are arranged between the side of the mounting plate 36 away from the contact pins 33 and the socket 3. The surfaces of the plurality of contact pins 33 are sleeved with the same baffle 34, and a plurality of first springs 35 are arranged between the baffle 34 and the mounting plate 36. The first springs 35 are sleeved on the circumferential surface of the contact pins 33, and the first springs 35 and the second springs 37 are arranged alternately.

[0031] The socket 3 can be plugged with the plug connector 4. The plug connector 4 includes a plug wire harness 46. A connection block 43 is provided on one side of the plug wire harness 46. A plug interface 41 is fixedly provided on the side of the connection block 43 away from the plug wire harness 46. A plurality of interfaces corresponding to the contact pins 33 are provided inside the plug interface 41. The contact pins 33 can be inserted into the corresponding interfaces to achieve electrical connection. The upper and lower top surfaces of the plug interface 41 are provided with elastic sheets 42. One end of the elastic sheet 42 is fixedly connected to the upper and lower bottom surfaces of the plug interface 41. An empty groove is provided in the middle of the upper and lower elastic sheets 42. A sliding frame 44 is slidably provided on the surface of the connection block 43. The upper and lower surfaces of the sliding frame 44 are rotatably provided with a transmission rod 45. The ends of the transmission rods 45 on both sides away from the sliding frame 44 are slidably connected to the empty groove of the elastic sheet 42.

[0032] When using this PCB board plug-in and pull-out processing device, it is necessary to plug the socket 3 and the plug connector 4 so that the PCB board can be electrically connected. The plug interface 41 of the plug connector 4 is inserted into the inner cavity of the socket 3. While inserting, the sliding frame 44 is moved to move the sliding frame 44 in the direction away from the plug interface 41, thereby driving the transmission rod 45 set on the upper and lower surfaces of the sliding frame 44 to rotate. The transmission rod 45 rotates in the direction close to the connection block 43 and drives the elastic sheets 42 on the upper and lower sides to rotate in the direction close to the plug interface 41. Thereby, the farthest distance between the elastic sheets 42 on both sides is reduced, so that it can smoothly enter the inner cavity of the socket 3 through the block 31. The staff electrically connects the contact pin 33 with the interface in the plug interface 41, and then releases the restriction on the sliding frame 44, and the elastic sheet 42 is restored to the initial position due to its own elastic potential energy. During the rotation of the elastic sheet 42, the transmission rod 45 and the sliding frame 44 are driven to move. The elastic sheets 42 on both sides of the initial position can be in contact with the block 31 to prevent the socket 3 from being separated from the socket 3, and the transmission rod 45 can be placed in the clearance opening 32 set in the middle of the block 31. The clearance openings 32 on both sides are set obliquely, and the distance between the clearance openings 32 on both sides gradually increases along the direction of entering the inner cavity. The same baffle 34 can be slidably arranged on the several contact pins 33 of the socket 3 to prevent the contact pins 33 from being contaminated and prevent dust from contacting the contact pins 33 to cause the device to short-circuit when connected. When it is necessary to cancel the connection between the socket 3 and the socket 3, the socket 3 is pushed in the direction of the socket 3 so that the elastic sheet 42 can be away from the block 31, thereby providing space for the elastic sheet 42 to rotate. Then move the sliding frame 44 on the surface of the connecting block 43, and the sliding frame 44 drives the elastic sheet 42 to move through the transmission rod 45, so that the staff can pull out the plug connector 4 from between the block 31 on both sides of the socket 3.

[0033] Working principle of the utility model: A PCB board plugging and unplugging processing device of the utility model is provided with an elastic sheet 42 and a sliding frame 44. The sliding frame 44 can drive the elastic sheet 42 to rotate through a transmission rod 45, so that when the socket 3 and the plug connector 4 are connected, the elastic sheet 42 can be controlled to rotate to fix or release the socket 3 and the plug connector 4; by providing a second spring 37 and a mounting plate 36, the socket 3 and the plug connector 4 can push the plug connector 4 when releasing the fixation, so that the elastic sheet 42 can be away from the block 31, thereby providing a rotation space for the elastic sheet 42 so that the elastic sheet 42 can rotate to drive the plug connector 4 to be removed from the block 31 on both sides of the socket 3.

[0034] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
