Therefore, the circuit board dismounting tool provided by the embodiments of the application can be applied to the electronic equipment shown in fig. 6, and particularly, the circuit board dismounting tool can be mounted in the mounting holes at the two ends of the upper layer of circuit board connector and the lower layer of circuit board connector, so that the circuit board dismounting convenience can be improved, the damage caused by the dismounting of the circuit board can be reduced, the assembly and dismounting operation time can be shortened, and the production and maintenance efficiency can be improved.
(III) mounting
Fig. 7 is a schematic diagram of connection of two layers of circuit boards in an electronic device by using the circuit board assembling and disassembling tool according to the embodiment of the application.
The circuit board dismounting tool provided in this embodiment passes the external thread section 104 at the bottom of the fixing rod 1 through the mounting hole of the lower circuit board, and is screwed and fixed with the external thread section 104 by a nut, so that other structures of the fixing rod 1 are fixedly arranged on the inner side end face (such as the upper side end face in fig. 7) of the lower circuit board. The two screwing connection posts 103 protruding from the upper end of the fixing rod 1 are screwed into the two spiral grooves 201 of the spiral sleeve in the spiral cylinder 2 in a one-to-one correspondence manner, and after the top end of the rod part of the spiral cylinder 2 passes through the upper circuit board, the middle thread section of the connecting screw 3 is screwed into the thread through hole 203 of the spiral cylinder 2.
At this time, the primary connection of the lower layer circuit board and the upper layer circuit board has been completed by a part of the structure (i.e., screw connection mechanism including a fixing rod 1, a screw cylinder 2, and a connection screw 3) in the circuit board assembling and disassembling tool.
(IV), specific usage modes
Fig. 8 is a schematic diagram illustrating the mounting and dismounting of two layers of circuit boards in an electronic device by using the circuit board dismounting tool provided by the embodiment of the application.
The upper layer and the lower layer of the two circuit boards are connected through the direct-insertion connector, when the two layers of the circuit boards are assembled, the handle 5 passes through the through hole 402 at the top end of the sleeve 4 and is sleeved on the screw rod switching post formed by the connecting screw rod 3 at the top end of the screw cylinder 2 through the two transverse limit grooves 401 at the opening end of the sleeve 4. At this time, based on the directions of the two spiral grooves 201 of the spiral sleeve in the spiral cylinder 2, the handle 5 can be rotated by hand in the clockwise direction (or in the anticlockwise direction), the handle 5 drives the sleeve 4 and the spiral cylinder 2 to rotate synchronously in the clockwise direction (or in the anticlockwise direction), the two screwing transfer posts 103 move upwards along the groove positions corresponding to the spiral grooves 201, drive the lower circuit board and the upper circuit board to be close to each other, and enable the upper end face and the lower end face of the spiral sleeve in the spiral cylinder 2 to be in contact with the upper circuit board and the lower circuit board respectively, so that the plugging of the connectors in the upper circuit board and the lower circuit board is realized, and the plugging size of the connectors is ensured. After the connector is inserted tightly, the handle 5 and the sleeve 4 are removed, and other parts are reserved on the upper circuit board and the lower circuit board so as to facilitate subsequent disassembly.
When the two layers of circuit boards are disassembled, the handle 5 passes through the through hole 402 at the top end of the sleeve 4, and the connecting screw 3 screwed at the top end of the spiral tube 2 is nested in the two transverse limit grooves 401 arranged at the opening end of the sleeve 4. At this time, based on the directions of the two spiral grooves 201 of the spiral sleeve in the spiral cylinder 2, the handle 5 can be rotated by hand in the anticlockwise direction (or in the clockwise direction), the handle 5 drives the sleeve 4 and the spiral cylinder 2 to rotate synchronously in the anticlockwise direction (or in the clockwise direction), the two screwing transfer posts 103 positioned on the top end surfaces of the two spiral grooves 201 move downwards relative to the spiral curved surface until screwing to the bottom of the spiral groove 201, and the screwing process drives the lower layer circuit board and the upper layer circuit board to be mutually far away, so that the connectors in the upper layer circuit board and the lower layer circuit board are separated, and the quick disassembly of the circuit boards is realized.
