[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0031] The embodiment of the utility model provides a splicing type driver with modularization and quick plug-pull function, in the driver, different components are divided into six modules according to functions, each module is independently detachable, the whole driver shell is divided into an upper plate 1, a lower plate 2, a left side plate 3, a right side plate 4, a back plate 5, a front panel upper 6, a front panel middle 7, a front panel lower 8, and the remaining parts include a handle 9, a positioning pin 10, a wire binding crossbeam 11, a back plate PCB 12, a circular connector 13, a module PCB 1401, a module shell 1402, a locking strip 1403, a puller 1404, a guide pin seat 1405, a connector plug 1406, a lamp plate PCB 15 and an electromagnetic shielding film 16.

[0032] Based on the structure of the module shell, the technical function of modular packaging of each component can be realized, and each plate body is provided with a mounting groove, so that the shell can be quickly disassembled and maintained conveniently.

[0033] The assembling process of the driver includes: installing the positioning pin 10 with a nut to the back plate 5, installing the binding beam 11 to the right side plate 4 and the upper plate 1, installing the handle 9 to the upper front plate 6 and the lower front plate 8, and installing the lamp plate PCB 15 to the upper front plate 6; connecting the left side plate 3, the right side plate 4, the upper plate 1 and the lower plate 2 with screws; installing the back plate PCB 12 to the side steps of the left side plate 3 and the right side plate 4 with screws; installing the back plate 5 with screws, and fixing the back plate PCB 12 to the back plate 5 with screws, which plays an auxiliary connecting role; inserting the six function modules 14 after the connection and fixation of the cables are completed; sequentially installing the upper front plate 6, the middle front plate 7 and the lower front plate 8; and finally installing the circular connector 13 and pasting the electromagnetic shielding film 16.

[0034] Each module is composed of a module PCB 1401, a module shell 1402, a locking strip 1403 and a puller 1404. The module PCB 1401 is distributed with through holes around the periphery, and can be installed to the module shell 1402 through screws. The puller 1404 is arranged on the left and right corners of the front face of each module, and the front and rear stop faces are left near the puller 1404 end of the horizontal groove of the left and right side plates. When the puller 1404 is pulled up and pushed into the module to contact the guide pin with the guide pin seat 1405, due to the cooperation of the pin hole and the connector plug socket, the resistance is large when it is continuously pushed in. The puller stop ear can be pressed against the front stop face of the left and right side plates by pressing the puller buckle, which can assist the module to be pushed into the driver until the puller buckle is buckled into the module groove, and the connector plug socket is inserted in place. When the module needs to be pulled out, the puller buckle is actuated, and the puller stop ear is pressed against the rear stop face of the left and right side plates, so that the force required to disconnect the connector plug 1406 on the module and the connector socket on the back plate PCB 12 is converted into the force of actuating the puller buckle, which plays a role in assisting pulling out.

[0035] The locking strip 1403 is arranged on the left and right sides of each module, and the locking strip 1403 is composed of a long adjusting screw stringing five trapezoidal structure blocks. The trapezoidal structure block at the end is fixed, and the remaining structure blocks can slide freely. After the module is connected to the back plate PCB 12, the adjusting screw of the locking strip 1403 can be tightened to make the trapezoidal structure blocks of the locking strip 1403 be extruded and protrude up and down to press the horizontal groove on the left and right side plates, so as to realize the locking of the module. When the module needs to be pulled out, the adjusting screw of the locking strip 1403 is loosened first, so that the trapezoidal structure blocks of the locking strip 1403 return to flat without protrusion.

[0036] All driver shells are made of aluminum alloy 7075-T651 material, the surface is conductive oxidation, and the outer surface is paint treated. The upper plate 1, the lower plate 2, the left side plate 3, the right side plate 4, the back plate 5, the upper front plate 6, the middle front plate 7 and the lower front plate 8 are all provided with installation positioning steps, and a sealing groove is reserved for installing a conductive sealing strip. The conductive adhesive is coated between the sealing strip and the shell, so as to realize the electromagnetic sealing of the driver.

[0037] The scheme provided in the application divides the driver into multiple functional modules according to functions, each of which comprises an independent module PCB and a module shell, and the plug-in and plug-out of the functional modules are realized in the form of slots, so that the maintenance is convenient, when a product fails, the faulty module can be pulled out to return to the factory for repair, and the module spare parts can be prepared in advance according to the needs, and the product reliability is improved.
