Description

Technical Field

[0001] This application relates to the field of enameled wire technology, and more particularly to an enameled wire protective sleeve. Background Technology

[0002] Enamelled wire is a type of wound wire consisting of a conductor and an insulation layer. It is manufactured by annealing bare wire and then repeatedly coating and baking it. It is widely used in motors, electrical appliances, and electronic equipment. During storage and transportation, enamelled wire needs to be stacked. Stacking can easily cause scratches or compression, and if the air humidity is high during storage, some of the wire can also become damp. Therefore, protective sleeves are necessary to protect the enamelled wire.

[0003] The existing enameled wire protective sleeve is directly covered on the outside of the enameled wire. It has the advantages of simple structure and low cost. However, there are still some defects in the process of using the sleeve. After the protective sleeve is covered, it cannot play a positioning role with the enameled wire. It is not convenient to pick up the enameled wire with the protective sleeve as a whole. Moreover, the stability of stacking protective sleeves is relatively poor (easy to axially deviate).

[0004] Therefore, this application proposes a protective sleeve for enameled wire. Utility Model Content

[0005] The purpose of this application is to provide a protective sleeve for enameled wires in response to the technical problems pointed out in the background art.

[0006] The technical solution of this application: A protective sleeve for enameled wire, comprising a winding drum and a connecting ring fixedly sleeved on the upper and lower ends of the winding drum, wherein a wire is wound around the side wall of the winding drum, and further comprising:

[0007] A protective sleeve fitted over the outside of the two connecting rings;

[0008] An annular groove is formed on the outer surface of the connecting ring. Several positioning blocks arranged in a ring are fixedly connected in the annular groove. Each positioning block has an inner positioning groove at its inner end in the same direction. The inner positioning groove is connected to the annular groove.

[0009] The protective sleeve includes a protective cover, and the upper inner wall of the protective cover is provided with a snap-fit ​​component, which engages with the positioning inner groove.

[0010] Preferably, the snap-fit ​​component includes a plurality of connecting blocks fixedly connected to the inner wall of the upper end of the protective cover. The plurality of connecting blocks are arranged in a ring, and a positioning plate is fixedly connected to the bottom end of each connecting block.

[0011] The positioning plate fits into the annular groove, and after rotation, one end of the positioning plate is inserted into the inner positioning groove.

[0012] Preferably, a protrusion is fixedly connected to the upper middle part of the protective cover. When stacked, the protrusion can fit into the winding drum. After the protrusion is inserted into the winding drum, the upper end of the protective cover abuts against the connecting ring above.

[0013] Preferably, the upper outer wall of the protective cover is provided with an annular groove, and the bottom end of the protective cover is fixedly connected with a positioning ring. When stacked, the positioning ring is inserted into the annular groove to play a role in longitudinal stacking and positioning.

[0014] Preferably, the number of positioning plates matches the number of positioning inner grooves. After several positioning plates are inserted into the annular groove, the protective cover is pressed down to make the positioning plates abut against the inner wall of the annular groove. Then, the protective cover is rotated to make one end of several positioning plates simultaneously inserted into several positioning inner grooves.

[0015] Preferably, when the end of the positioning plate is inserted into the positioning groove, the inner wall of the protective cover contacts the outer surface of the upper connecting ring.

[0016] Compared with the prior art, this application has the following beneficial technical effects:

[0017] This application provides an annular groove and a positioning inner groove at the outer end of the connecting ring, and a snap-fit ​​part on the inner wall of the protective cover. The positioning plate is connected with the positioning inner groove, so that the protective cover and the connecting ring can play a longitudinal positioning role. When the protective cover is lifted directly upward, the protective cover will not detach from the enameled wire, which makes it easy to pick up the enameled wire. The protective cover can also be removed upward after being rotated at a certain angle, which allows for flexible operation.

[0018] By opening an annular groove on the upper outer wall of the protective cover and fixing a positioning ring to the bottom of the protective cover, the positioning ring is inserted into the protective cover when stacking, which can play a role in positioning adjacent enameled wires and prevent stacking from deviating from the axis, thus improving the stability of stacking.

[0031] Example

[0032] like Figures 1-4 As shown, the present application proposes a protective sleeve for enameled wire, including a winding drum 2 and connecting rings 1 fixedly sleeved on the upper and lower ends of the winding drum 2. The side wall of the winding drum 2 is wound with a wire (not shown in the figure), and also includes a protective sleeve body 6 sleeved on the outside of the two connecting rings 1. The protective sleeve body 6 can protect the enameled wire, prevent the enameled wire from getting damp, and prevent the enameled wire from being oxidized during storage.

[0033] It also includes an annular groove 3 formed on the outer surface of the connecting ring 1, and a number of positioning blocks 4 arranged in a ring are fixedly connected in the annular groove 3. Each positioning block 4 has a positioning inner groove 5 formed on its inner end in the same direction. The positioning inner groove 5 is in communication with the annular groove 3. The protective sleeve 6 includes a protective cover 61. The upper inner wall of the protective cover 61 is provided with a snap-fit ​​member 7. The snap-fit ​​member 7 is engaged with the positioning inner groove 5.

[0034] Specifically, the snap-fit ​​component 7 includes several connecting blocks 71 fixedly connected to the inner wall of the upper end of the protective cover 61. The connecting blocks 71 are arranged in a ring, and a positioning plate 72 is fixedly connected to the bottom end of each connecting block 71. The positioning plate 72 fits into the annular groove 3, and after rotation, one end of the positioning plate 72 is inserted into the positioning inner groove 5. A protrusion 62 is fixedly connected to the middle of the upper end of the protective cover 61 to facilitate the operation of the protective cover 61. When stacked, the protrusion 62 can fit into the winding drum 2. When the protrusion 62 is inserted into the winding drum 2, the upper end of the protective cover 61 abuts against the connecting ring 1 above.

[0035] Furthermore, the upper outer wall of the protective cover 61 is provided with an annular groove 63, and the bottom end of the protective cover 61 is fixedly connected with a positioning ring 64. When stacked, the positioning ring 64 is inserted into the annular groove 63, which can play a role in positioning adjacent enameled wires, preventing stacking from deviating from the axis, improving stacking stability, and the structure design is simple and easy to operate. The number of positioning plates 72 matches the number of positioning inner grooves 5. After several positioning plates 72 are inserted into the annular grooves 3, the protective cover 61 is pressed down to make the positioning plates 72 abut against the inner wall of the annular groove 3. Then, the protective cover 61 is rotated so that one end of several positioning plates 72 is simultaneously inserted into several positioning inner grooves 5. When the end of the positioning plate 72 is inserted into the positioning inner groove 5, the inner wall of the protective cover 61 contacts the outer surface of the upper connecting ring 1. The positioning plate 72 is connected to the positioning inner groove 5, so that the protective cover 61 and the connecting ring 1 play a longitudinal positioning role. When the protective cover 61 is lifted directly upward, the protective cover 61 will not detach from the enameled wire, thus making it easy to take out the enameled wire. The protective cover 61 can be removed upward after being rotated at a certain angle.

[0036] The working principle of this embodiment is as follows: When applying the protective cover, first, the protective cover 61 is placed over the outside of the enameled wire. After application, the protective cover 61 is rotated slightly while pressing down. When several positioning plates 72 are aligned with several annular grooves 3, they will insert into the annular grooves 3. After the positioning plates 72 are fully inserted into the annular grooves 3, the protective cover 61 is rotated at a certain angle so that the ends of the positioning plates 72 are inserted into the positioning inner grooves 5, thus completing the longitudinal positioning of the protective cover 61 and the enameled wire. When the protective cover 61 is lifted, the enameled wire is lifted synchronously and stably. After the protective cover 61 is applied, it can provide moisture protection and impact protection for the enameled wire.

[0037] When stacking enameled wires, the positioning ring 64 will engage with the annular groove 63 of the lower protective cover 61, and the protrusion 62 on the lower protective cover 61 will be inserted into the winding spool 2 of the upper enameled wire, so that the enameled wires have a stable support state when stacked and will not easily tilt.

[0038] The above specific embodiments are merely preferred embodiments of this application. Based on the technical solutions of this application and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments. The above specific embodiments are merely explanations of this application and are not limitations on this application.
