Description

Technical Field

[0001] This utility model relates to a cooling fan frame structure, and more particularly to a fan frame and fan with terminal slots. Background Technology

[0002] Existing fans may have a wire (e.g., a power cord), one end of which can be connected to a circuit board inside the fan, and the other end of which can extend from the fan frame and be electrically connected to an external power source. This allows the external power source to supply power to the fan, driving the fan wheel to rotate. However, during fan installation, the protruding wire needs to be managed, causing assembly inconvenience; and the wire is easily pulled during connection to the external power source, leading to wire damage or detachment of the solder joints between the wire and the circuit board. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a fan frame that can position the wires on the fan frame, thereby providing better installation convenience.

[0004] The directional terms or similar terms used throughout this utility model, such as "front", "back", "left", "right", "top", "bottom", "inner", "outer", "side", etc., are mainly for reference to the directions in the accompanying drawings. Each directional term or similar term is only used to assist in explaining and understanding the various embodiments of this utility model and is not intended to limit this utility model.

[0005] The use of the quantifiers “a” or “an” for the elements and components described throughout this utility model is merely for convenience and to provide the general meaning of the scope of this utility model; in this utility model, it should be interpreted as including one or at least one, and a single concept also includes multiple cases, unless it clearly means otherwise.

[0006] The terms “first,” “second,” … and “Nth” used throughout this utility model are mainly used to distinguish different elements or features (such as elements, directions, or steps), and do not indicate the maximum or minimum number of these elements or features possessed by a corresponding subject or method, nor do they limit the order of priority.

[0007] The terms "combination," "integration," or "assembly" used throughout this utility model mainly include those that allow for separation without damaging the components after connection, or those that make the components inseparable after connection. Those skilled in the art can choose the appropriate term based on the material of the components to be connected or the assembly requirements.

[0008] The fan frame of this utility model includes: a fan frame body having a first plate and a second plate that are axially opposite each other, with a side wall connected between the first plate and the second plate; and a terminal positioning member located between the first plate and the second plate, the terminal positioning member having a connecting hole.

[0009] Therefore, the fan frame of this utility model has a terminal positioning member in the fan frame body, and the terminal positioning member has a connecting hole. The terminal of the wire can be positioned in the connecting hole, so that the wire connected to the terminal can be stably located in the fan frame body and will not be damaged by pulling during installation. In addition, the interface of the external power supply can be easily connected to the terminal of the wire, which has the effect of convenient installation.

[0010] The first plate has a protrusion that extends radially outward from the side wall. The second plate also has a protrusion that extends radially outward from the side wall. The protrusions of the first and second plates, together with an outer peripheral wall of the side wall, form an accommodating space, where the terminal positioning member is located. This ensures that the terminal positioning member does not extend radially beyond the functional area of ​​the fan frame body.

[0011] At least one of the two protrusions in the accommodating space has a cable management groove. Thus, the cable can be accommodated in the cable management groove, allowing the cable to be neatly organized and providing convenient cable management.

[0012] The side wall is formed circumferentially around an axis of the fan frame body, and the extension direction of the connecting hole is tangential to the side wall. This prevents the side wall from obstructing the extension path of the terminal wire.

[0013] The mating hole extends through the two opposite end faces of the terminal positioning member, forming two openings. This allows the terminal to be fitted into either opening of the mating hole, providing ease of assembly.

[0014] The terminal positioning member has a through groove that extends through the outer wall of the terminal positioning member to connect with the mating hole. The through groove extends along the outer wall of the terminal positioning member towards opposite ends of the terminal positioning member, and connects with two opposite openings of the mating hole respectively. In this way, the through groove allows the wire to enter the mating hole laterally, which facilitates assembly.

[0015] The fan of this utility model includes: the aforementioned fan frame; a stator assembly located on the fan frame body; a fan wheel, the stator assembly driving the fan wheel to rotate; and a wire electrically connected to the stator assembly, the wire having a terminal located in the mating hole of the terminal positioning member. Thus, during installation, the wire will not be damaged by pulling, and the external power supply interface can be easily connected to the terminal of the wire, achieving the effect of convenient installation.

[0016] The terminal has an interface end and a wiring end, the wiring end being connected to the wire. The terminal has a shoulder, and a positioning block is provided inside the mating hole. The shoulder of the terminal abuts against the positioning block. In this way, the terminal can be positioned at a predetermined position within the mating hole. Attached Figure Description

Detailed Implementation

[0019] To make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments of this utility model are described below in detail with reference to the accompanying drawings; in addition, those symbols that are marked with the same symbols in different drawings are considered to be the same and their descriptions will be omitted.

[0020] Please refer to Figure 1 As shown, it is a preferred embodiment of the fan frame F of the present invention, including a fan frame body 1 and a terminal positioning member 2, the terminal positioning member 2 being located on the fan frame body 1.

[0021] The fan frame body 1 can be an axial flow fan frame or a centrifugal fan frame. In this embodiment, the fan frame body 1 is an axial flow fan frame. The fan frame body 1 can be used to assemble a stator assembly T and a fan wheel P to form a fan G. The fan frame body 1 can have two opposing air outlets W at a central axis O. The two air outlets W can be an air inlet and an air outlet respectively, depending on the rotation direction of the fan wheel P. The airflow direction at the two air outlets W is not limited in this invention. The stator assembly T can be electrically connected to a conductor L. The conductor L can be electrically connected to an external power source through a terminal L1. The conductor L can be, for example, a power line or a signal transmission line. Furthermore, the terminal L1 may have an interface terminal L2 and a wiring terminal L3. The interface terminal L2 is used to connect to an external power source, and the wiring terminal L3 is connected to the wire L, thereby supplying power to the stator assembly T to drive the fan wheel P to rotate. Furthermore, the fan wheel P may have a magnetic element, and the stator assembly T may have an iron core coil to generate a magnetic field when energized to drive the fan wheel P to rotate. This is something that those skilled in the art will understand, and will not be elaborated here.

[0022] In detail, the fan frame body 1 may have a first plate 11 and a second plate 12 axially opposed to each other. The frame body 1 has a side wall 13 connected between the first plate 11 and the second plate 12. Furthermore, the side wall 13 may surround the accommodating space S in a circumferential direction relative to the axis O. The first plate 11 has a protrusion 11a, which may extend radially outward from the side wall 13. The second plate 12 has a protrusion 12a, which may extend radially outward from the side wall 13. The two protrusions 11a and 12a may be located at one corner of the fan frame body 1. The two protrusions 11a and 12a and an outer peripheral wall 131 of the side wall 13 may together surround and form an accommodating space S.

[0023] Please refer to Figure 1 , Figure 2As shown, the terminal positioning member 2 can be integrally formed with the fan frame body 1, or the terminal positioning member 2 can be assembled and located on the fan frame body 1 by means of, for example, snap-fitting, welding, or bonding. Furthermore, the terminal positioning member 2 can be located in the accommodating space S, such that the terminal positioning member 2 can be located between the first plate 11 and the second plate 12. For example, the terminal positioning member 2 can be located on the side wall 13, so that the terminal positioning member 2 does not extend radially beyond the fan frame body 1. The terminal positioning member 2 can have a connecting hole 21 with an opening 21a. The terminal L1 of the wire L can be connected to the connecting hole 21 through the opening 21a. The connecting hole 21 can have a slot corresponding to the terminal L1, so that the terminal L1 can be securely located in the connecting hole 21, thereby positioning the terminal L1 through the connecting hole 21, and the interface end L2 of the terminal L1 can be exposed through the opening 21a of the connecting hole 21.

[0024] In this embodiment, the extending direction D of the connecting hole 21 can be the tangential direction of the side wall 13. This avoids the side wall 13 obstructing the extension path of the wires (e.g., the wire L and the external power line connected to the interface end L2) at opposite ends of the terminal L1. Furthermore, at least one of the two protrusions 11a and 12a of the accommodating space S can have a cable management groove 14. After the terminal L1 is positioned in the connecting hole 21, the wire L can be accommodated in the cable management groove 14, allowing the wire L to be neatly organized and providing convenient cable management.

[0025] Preferably, the mating hole 21 can be a through hole, extending through both opposite end faces of the terminal positioning member 2 to have two openings 21a. Thus, the terminal L1 can be mated into the mating hole 21 by selecting either opening 21a according to the extension direction of the wire L, providing convenient assembly. Furthermore, the terminal L1 can sequentially have a large-diameter section L11 and a small-diameter section L12 from the interface end L2 to the wiring end L3. A shoulder L13 can be formed between the large-diameter section L11 and the small-diameter section L12 through a diameter difference. A positioning block 21b can be provided within the mating hole 21, located between the two opposite openings 21a. When the terminal L1 is mated into the mating hole 21 from the direction of the two openings 21a, the shoulder L13 of the terminal L1 can abut against the positioning block 21b, allowing the terminal L1 to be positioned at a predetermined position within the mating hole 21.

[0026] Furthermore, the terminal positioning member 2 may have a through groove 22, which penetrates the outer wall of the terminal positioning member 2 and the mating hole 21, thus connecting the through groove 22 with the mating hole 21. The through groove 22 extends along the outer wall of the terminal positioning member 2 towards opposite ends of the terminal positioning member 2, and the through groove 22 respectively connects with the two opposite openings 21a of the mating hole 21. In this way, the through groove 22 allows the wire L to enter the mating hole 21 laterally, and then the terminal L1 is mated to the mating hole 21, which facilitates assembly.

[0027] In summary, the fan frame of this utility model has a terminal positioning component in the fan frame body, and the terminal positioning component has a connecting hole. The terminal of the wire can be positioned in the connecting hole, so that the wire connected to the terminal can be stably located in the fan frame body and will not be damaged by pulling during installation. It also allows the interface of the external power supply to be easily connected to the terminal of the wire, thus achieving the effect of convenient installation.
