Detailed Description
The project is further described with reference to the specific embodiment and the attached drawing description.
First, applicants have found, through a number of practices: the PCB is fixed on a certain supporting platform, and an outer cover is sleeved on the PCB. And then the outer cover and the supporting platform are fixedly connected in a bolt connection mode, but the fixing mode is troublesome in dismounting and mounting, one outer cover is required to be screwed down or dismounted, the mounting and dismounting cannot be carried out quickly, and the process is complicated.
In order to save the process and realize quick mounting and dismounting, the applicant designs a heat dissipation type packaging structure for a PCB, comprising: supporting platform 1, mounting groove 2, cylinder 3, dustcoat 4, hollow sleeve 5, stopper 6, spacing groove 7, spacing hole 8, spliced pole 9, bolt 10, snap ring 11, annular boss 12, bent plate 13, connecting pin 14, connecting piece 15, deflector 16, guide post 17, guide bar 18.
As shown in fig. 1 and 2, a plurality of mounting grooves 2 are formed in the supporting platform 1, and the mounting grooves 2 are used for fixing a PCB. The number of the cylinders 3 is four, and the cylinders are respectively fixed at four top corners of the mounting groove 2.
The four top corners of the outer cover 4 are provided with hollow sleeves 5, the positions of the hollow sleeves 5 correspond to the positions of the cylinders 3, and when the outer cover 4 is buckled on the supporting platform 1, the cylinders 3 are just inserted into the hollow sleeves 5, so that the locking and positioning between the cylinders 3 and the hollow sleeves 5 are realized. As shown in fig. 3 and 4, a limiting block 6 in the vertical direction is fixed on one side of the cylinder 3, and three limiting grooves 7 are sequentially arranged on the limiting block 6 from top to bottom. The hollow sleeve 5 is provided with a limiting hole 8, the limiting hole 8 and the limiting block 6 are arranged at the same side, and the limiting hole 8 is connected with the limiting groove 7 through a clamping component. The connection mode that adopts the joint replaces screw nut's rotation, the simple operation to spacing groove 7 is a plurality of, can realize that not co-altitude dustcoat 4 is fixed.
Specifically, the joint subassembly includes: inside is hollow and both ends open's spliced pole 9, spliced pole 9 sets up the outside of hollow sleeve 5 and with spacing hole 8 is concentric, still includes to pass simultaneously spliced pole 9 and spacing hole 8 and extend to the bolt 10 in the spacing groove 7. I.e. the bolt 10 is used to achieve a locking position between the hollow sleeve 5 and the cylinder 3.
However, in the above structure, the latch 10 is easily separated from the coupling post 9 or cannot firmly lock the hollow sleeve 5 and the cylinder 3. Consequently the inner wall of the one end of spliced pole 9 keeping away from spacing groove 7 is equipped with inwardly extending snap ring 11, the surface of bolt 10 is provided with annular boss 12 along its circumference, annular boss 12 is located between spacing hole 8 and the snap ring 11, the external diameter of annular boss 12 is greater than spacing hole 8's internal diameter. When the annular boss 12 abuts against the limiting hole 8, the bolt 10 abuts against the limiting groove 7, and locking and fixing are achieved; when the annular boss 12 abuts against the clamping ring 11, the plug pin 10 is separated from the limiting hole 8, and the plug pin 10 is not separated from the connecting column 9 due to the limitation of the clamping ring 11.
Through the structure, the locking and positioning of the cylinder 3 and the hollow sleeve 5 can be quickly realized, but the bolt 10 is small and is not well controlled during operation. To this end, the clamping assembly further comprises: a bending plate 13 fixed on the connecting column 9, a connecting pin 14 tightly installed at one end of the bolt 10 far away from the limiting hole 8, and a connecting piece 15 hinged with the tail end of the bending plate 13 at the central position; the connecting end of the connecting piece 15 is rotatably clamped between the connecting pin 14 and the connecting column 9. In order to allow the connecting element 15 to rotate without resistance under the action of external forces, the connecting ends of the connection are hook-shaped. The connecting piece 15 capable of controlling the bolt 10 is arranged, so that the force application object can be directly found and the force can be applied conveniently.
In order to enable the cylinder 3 to be accurately aligned with the hollow pipe sleeve, guide plates 16 are vertically and upwardly fixed on two sides of the supporting platform 1, the guide plates 16 are used for guiding two sides of the outer cover 4, the accurate alignment of the outer cover 4 and the supporting platform 1 is controlled, and meanwhile, the guide plates 16 increase the sealing performance of the joint of the outer cover 4 and the supporting platform 1 and can play a role in dust prevention.
And a guide post 17 is arranged on one side of the column 3, the guide post 17 is of an open structure, a guide rod 18 is fixed on one side of the hollow sleeve 5, and the position of the guide rod 18 corresponds to that of the guide post 17. Namely, after the guide post 17 is clamped with the guide rod 18, the cylinder 3 can be directly ensured to be accurately aligned with the hollow pipe sleeve.
On this basis, in order to have a better heat dissipation function, a plurality of grooves are formed on the inner surface of the outer cover 4. The thickness of the outer cover 4 is reduced, and the heat dissipation performance is improved.
The utility model discloses a theory of operation: when the assembly is needed, the guide plates on the two sides of the supporting platform are matched with the outer cover, the outer cover is located right above the supporting platform, then the clamping positions of the guide columns and the guide rods are aligned, and the cylinders are inserted into the hollow pipe sleeves. According to the height of the outer cover, a corresponding limiting groove on a limiting block on the adjusting cylinder corresponds to the limiting hole, the bottom end of the connecting piece is loosened, the bolt is inserted into the limiting hole and abuts against the limiting groove, and locking and positioning are achieved.
