Description

Technical Field

[0001] The utility model relates to the field of computer fans, in particular to a double-positioning building block fan. Background Art

[0002] With the development of building block computer fans, the convenience of their combination has been verified by the market, and the corresponding market competitiveness has become more intense.

[0003] For example, the existing Chinese patent CN202322572093.2 adopts a single snap-on structure and cooperates with magnets to achieve mutual splicing between shells, but its cost is correspondingly high, and the mold cost is also high, which affects the market competitiveness and market share. Utility Model Content

[0004] The main purpose of the utility model is to provide a double-positioning building block fan, aiming to improve the existing one.

[0005] To achieve the above purpose, the utility model provides a dual positioning building block fan, comprising:

[0006] A housing, the housing being rectangular and having four side surfaces;

[0007] A buckle structure, wherein the buckle structure is disposed on side walls of at least two side surfaces, wherein the side surfaces include a first side surface and a second side surface, and the first side surface and the second side surface are disposed opposite to or adjacent to each other;

[0008] The buckle structure includes a buckle portion provided on a first side surface and a buckle slot provided on a second side surface, and the buckle portion can be switched between a position extending into the buckle slot and a position exiting the buckle slot.

[0009] The first side surface is provided with two engaging portions at intervals along the width direction of the first side surface, and each two engaging portions form a group. The first side surface is provided with at least two groups of engaging portions along its length direction.

[0010] The clamping portion is gradually expanded from the shell to the outside and forms an isosceles trapezoidal shape, and the buckling groove is an isosceles trapezoidal groove; (the clamping portion provided with an inclined surface can make the clamping effect better, that is, the inclined surfaces offset each other, reduce the clamping gap, and avoid vibration generated by the fan when in use.)

[0011] The electrical connection portion includes a male terminal disposed on the first side surface and a female terminal disposed on the second side surface.

[0012] In the actual design, the locking parts are spaced apart so that the force on the fulcrum is more even and the locking process is smoother. At the same time, two groups of locking parts are provided to make the installation of the locking points simpler, and the two second locking parts are spaced apart so that they are independent of each other when locked. Therefore, during mold production, the shell includes an upper shell and a lower shell, avoiding alignment problems caused by defects in production, that is, the two locking parts do not need to fit each other, so the yield rate is higher, effectively reducing production costs.

[0027] like Figures 1 to 4 As shown, a dual positioning building block fan comprises:

[0028] A housing 1, wherein the housing 1 is rectangular and has four side surfaces;

[0029] A buckle structure, wherein the buckle structure is disposed on side walls of at least two side surfaces, wherein the side surfaces include a first side surface 11 and a second side surface 12, and the first side surface 11 and the second side surface 12 are disposed opposite to or adjacent to each other;

[0030] The buckle structure includes a buckle portion 21 disposed on the first side surface 11 and a buckle slot 22 disposed on the second side surface 12. The buckle portion 21 can be switched between a position extending into the buckle slot 22 and a position exiting the buckle slot 22.

[0031] The first side surface 11 is provided with two engaging portions 21 at intervals along the width direction thereof, and each two engaging portions 21 form a group. The first side surface 11 is provided with at least two groups of engaging portions 21 along its length direction.

[0032] The clamping portion 21 is gradually expanded from the shell 1 outward to form an isosceles trapezoidal shape, and the locking groove 22 is an isosceles trapezoidal groove; the clamping portion set with inclined surfaces can make the clamping effect better, that is, the inclined surfaces offset each other, reducing the clamping gap and avoiding vibration generated by the fan when in use.

[0033] The electrical connection portion includes a male terminal disposed on the first side surface 11 and a female terminal disposed on the second side surface 12 .

[0034] In the actual design, the engaging parts 21 are arranged at intervals, so that the force on the fulcrum is more evenly distributed and the engaging process is smoother. At the same time, two groups of engaging parts 21 are provided, so that the installation of the engaging points is simpler, and the two second engaging parts 21 are arranged at intervals so that they are independent of each other when engaged. Therefore, during mold production, the shell 1 includes an upper shell and a lower shell, avoiding the alignment problem caused by defects in production, that is, the two engaging parts 21 do not need to fit each other, so the yield rate is higher, and the production cost is effectively reduced.

[0035] Specifically, the male terminal is a plurality of elastic PIN pins 31 arranged at intervals, and the female terminal is a gold finger 32 matched with the elastic PIN pin 31. The commonly used gold finger 32 (ie, the PCB board is provided with a plurality of metal contact surfaces) is adopted, which effectively reduces the production cost and the assembly cost.

[0036] In the embodiment of the utility model, the male terminal is a Type-c male connector 41, and the female terminal is a Type-C female connector.

[0037] Specifically, the Type-C male connector 41 and the Type-C female connector 42 are arranged horizontally or vertically. (With the development of connector standardization, the standardization of interfaces is actively promoted in the field of electronics. By setting a Type-C connector on the fan, when the fan is used alone or set in a chassis, it can be electrically connected through a Type-C data cable or a Type-C connector adapter, which effectively improves the convenience of use. According to the current Type-C connector combination, the general price is about 0.3 yuan, and the gold finger 32 structure is also comparable to the price of the Type-C connector, which can realize diversified production designs (i.e., modifications according to customer needs); for example, the slot of the housing 1 is set to a Type-C universal slot, and then backward compatible with the gold finger 32 structure.

[0038] In the embodiment of the utility model, a through groove 5 is recessed on one side of the buckling groove 22 , and the height of the through groove 5 is greater than the sum of the heights of the two buckling grooves 22 , thereby forming a clearance position to facilitate the engagement portion to extend into the buckling groove 22 .

[0039] Specifically, the engaging portion is provided with two inclined surfaces, and the ends of the inclined surfaces away from the housing 1 are provided with chamfered portions 100 , thereby facilitating the engaging portion to be inserted into the buckling groove 22 .

[0040] In the embodiment of the utility model, the shell 1 includes an upper shell and a lower shell, and two buckling parts are respectively formed on the upper shell and the lower shell. When the upper shell and the lower shell are combined with each other, a connecting line 6 is formed between the two, and the two buckling parts are symmetrically arranged with respect to the connecting line 6.

[0041] Specifically, the male terminal and the female terminal in the same housing 1 are connected via cables or flexible printed circuit boards (FPCs), wherein the use of flexible printed circuit boards can realize built-in wireless circuits, making installation easier, and LED lamps can be directly installed on the flexible printed circuit boards, making production and assembly simpler and more stable.

[0042] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
