Description

Technical Field

[0001] This utility model relates to a stepper motor cable outlet cover. Background Technology

[0002] Traditional two-phase stepper motors typically use a wire frame directly connected to pins for power supply wiring, which has the following technical drawbacks:

[0003] 1. Significant safety hazards: It is difficult to keep the pins perpendicular to the wire frame, resulting in uneven spacing between the pins. This can easily cause exposed wire ends wrapped around the pins to touch each other, leading to short circuits.

[0004] 2. Lack of protection: The lack of positioning and support during external connection can easily lead to loose connections and broken enameled wires. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a stepper motor cable outlet cover, which ensures uniform pin spacing through a protective structure, avoiding the risk of short circuits, while providing reliable positioning and support for external connections, effectively solving the problems pointed out in the background art.

[0006] The technical solution adopted in this utility model is:

[0007] A stepper motor cable outlet cover includes a housing connection part and a cable support part fixed together. The cable support part has four pin holes, and the housing connection part extends laterally out of the cable support part.

[0008] Preferably, the housing connection part has an arc-shaped structure.

[0009] Preferably, the outer surface of the housing connection part matches the inner arc surface of the housing.

[0010] Preferably, the housing connection part has two parts, which are symmetrically fixed on both sides of the wire frame support part.

[0011] Preferably, the two housing connection parts are connected to the wire frame support part via connection plates.

[0012] Preferably, the housing connection part, the connection plate and the wire frame support part are integrally formed.

[0013] The innovative points of this utility model are as follows:

[0014] 1. Protective structural design:

[0015] This utility model ensures uniform pin spacing by opening four pin holes on the wire frame support, avoiding the risk of short circuits caused by exposed wire ends touching each other in the traditional method. This design significantly improves the safety of stepper motor wiring.

[0016] 2. The arc-shaped structure of the housing connection:

[0017] The housing connection part adopts an arc design and matches the inner arc surface of the housing, so that the cable outlet cover can fit tightly into the housing, enhancing the stability and sealing of the connection. In addition, the two symmetrical housing connection parts are connected to the cable frame support part through the connecting plate, which further improves the stability of the overall structure and reduces the use of materials.

[0018] 3. One-piece molding technology:

[0019] The housing connection, connecting plate and wire frame support are made of one piece, which simplifies the manufacturing process, reduces assembly steps, lowers production costs, and improves the structural strength and durability of the product.

[0020] 4. Symmetrical design of the double-casing connection:

[0021] The two housing connection points are symmetrically distributed on both sides of the wire frame support, which not only optimizes the stress distribution but also provides dual positioning and support for external connections, effectively preventing problems such as loose connections and broken enameled wires.

[0022] This invention ensures uniform pin spacing through a protective structure, avoiding the risk of short circuits, while providing reliable positioning and support for external connections. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0033] like Figure 1-2 As shown, a stepper motor cable outlet cover includes a housing connecting part 1 and a cable support part 2 fixed together. The cable support part 2 has four pin holes 3. The housing connecting part 1 extends laterally out of the cable support part 2.

[0034] The housing connection part 1 has an arc-shaped structure, and the outer side of the housing connection part 1 matches the inner arc surface of the housing.

[0035] There are two housing connection parts 1, which are symmetrically fixed on both sides of the wire frame support part 2. The two housing connection parts 1 are respectively connected to the wire frame support part 2 through the connecting plate 4.

[0036] The housing connecting part 1, the connecting plate 4, and the wire frame support part 2 are integrally formed.

[0037] like Figure 3 As shown, the motor housing 5 has a through hole 7 at the location of the wire frame 6, which matches the wire frame support 2, so that the wire frame support 2 can pass through the through hole 7. The housing connection part 1 is positioned inside the housing 5. When this utility model is installed on the motor, the bottom of the wire frame support 2 abuts against the wire frame 6 and is pushed outward by the wire frame 6. The outer side of the housing connection part 1 abuts against the inner side of the housing 5 and is pushed inward by the housing 5. In this way, the wire outlet cover is stably fixed.

[0038] 1. Pin fixing and insulation protection:

[0039] The wire frame support 2 is provided with four pin holes 3 for fixing the power pins of the stepper motor, ensuring that the pin spacing is uniform and avoiding short circuit problems caused by exposed wire ends or too close spacing.

[0040] The pin hole 3 effectively locks and positions the pin to prevent poor contact or wire breakage due to external pulling or vibration.

[0041] 2. Housing connection and positioning support:

[0042] The housing connection part 1 fits tightly against the inner arc surface of the stepper motor housing, and cooperates with the clamping between the wire frame and the wire frame support part 2 to ensure a stable connection between the wire outlet cover and the motor housing.

[0043] The symmetrically designed housing connection 1 (one on each side) provides balanced support, preventing the cable outlet cover from loosening or tilting due to uneven force on one side.

[0044] The connecting plate serves as a transition structure, allowing the height of the wire frame support 2 to be designed according to requirements.

[0045] 3. Advantages of one-piece molding structure:

[0046] The housing connecting part 1, the connecting plate 4 and the wire frame support part 2 are integrally injection molded, reducing assembly steps and avoiding loosening or gap problems caused by splicing multiple parts;

[0047] The overall structure is more robust and can withstand higher mechanical stresses (such as vibration and impact), making it suitable for harsh environments such as industrial automation.

[0048] This invention is applicable to various two-phase stepper motors, and is especially suitable for industrial applications requiring high reliability and safety.

[0049] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
