Abstract
Description
Technical Field
[0001] This disclosure relates to the field of linear compressor technology, and more particularly to a conductive electrode, wiring structure, linear motor, and linear compressor. Background Technology
[0002] Linear compressors are piston compressors that utilize linear motors. They have advantages such as compact structure, light weight, oil-free or low-lubricating oil operation, and excellent variable capacity characteristics. As a result, they are being used more and more widely and have become a major development direction for high-efficiency compressors in small refrigeration units.
[0003] A linear motor consists of a stator and a mover. The mover performs linear reciprocating motion along the axial direction. The moving-coil linear motor is a widely used structural form. The moving part of a moving-coil linear motor is an energized coil. The stator can be energized by an excitation coil or a permanent magnet, with permanent magnets being more commonly used now. During operation, the permanent magnet and the iron core form a stable radial magnetic field in the annular air gap between the inner and outer iron cores. The coil is located in the magnetic gap and generates an axial electromagnetic force when energized. When the current is alternating current, the electromagnetic force on the coil changes direction accordingly, thereby driving the piston to perform axial reciprocating motion, compressing and expanding the working gas to do work.
[0004] When a leaf spring assembly serves as a support structure, it also functions as part of the coil circuit due to its own conductivity. In the prior art, the ends of the coils are partially welded to the side of the leaf spring to electrically connect the leaf spring to the wires. However, this method causes the ends of the wires to protrude outwards from the side of the leaf spring, resulting in irregular gaps between the contact surfaces of the multi-layer leaf spring assembly fitted on the mover. This not only affects the movement of the mover and the flatness of the leaf spring installation, but also affects the operational reliability of the leaf spring. Summary of the Invention
[0005] To solve the above-mentioned technical problems, or at least partially solve them, this disclosure provides a conductive electrode, a wiring structure, a linear motor, and a linear compressor.
[0006] This disclosure provides a conductive electrode for attaching and fixing to a leaf spring and electrically connecting the leaf spring to a wire, including a fixing ring and a wire threading member disposed on the fixing ring. The wire threading member is disposed on the outer circumferential surface of the fixing ring and has a wire threading portion for the wire to pass through.
[0007] Optionally, there may be multiple threading members, which are spaced apart circumferentially along the fixing ring.
[0008] Optionally, the number of threading components is three.
[0009] Optionally, the first side of the threading member is flush with the first side of the fixing ring for fitting and fixing with the leaf spring, and the second side of the threading member is provided with a groove formed by recessing towards the first side of the threading member, the bottom surface of the groove being lower than the second side of the fixing ring.
[0010] Optionally, one side of the threading member is flush with or protrudes from the second side of the fixing ring.
[0011] Optionally, the groove is disposed adjacent to the outer circumferential surface of the fixing ring, and the groove connects the threading portion and the outer circumferential surface of the fixing ring.
[0012] Optionally, the groove is an annular shape concentrically arranged with the fixing ring, and the inner sidewall of the groove is formed on the outer circumferential surface of the fixing ring.

One side of the conductive electrode is fitted and fixed to the leaf spring, and the fixing ring is correspondingly arranged with the inner fixing hole of the leaf spring.

[0019] The technical solution provided in this disclosure has the following advantages compared with the prior art:
[0020] This disclosure provides a conductive electrode, including a fixing ring and a wire guide disposed on the fixing ring. The wire guide is disposed on the outer circumferential surface of the fixing ring and has a wire guide portion for a wire to pass through. In use, the conductive electrode is fixed in contact with a leaf spring.

[0028] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0029] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.
[0030] like Figures 1 to 4 As shown in the embodiment of this disclosure, a conductive electrode is provided for attaching and fixing to a leaf spring and electrically connecting the leaf spring to a wire. The conductive electrode includes a fixing ring 303 and a wire threading member 304 disposed on the fixing ring 303. The wire threading member 304 is disposed on the outer circumferential surface of the fixing ring 303, and has a wire threading portion 301 for the wire to pass through. In use, the conductive electrode is attached and fixed to the leaf spring. The wire passes through the wire threading portion 301 and is electrically connected to the conductive electrode, thereby realizing the electrical connection between the wire and the leaf spring through the conductive electrode, and energizing the leaf spring. The setting of the conductive electrode increases the contact area of the electrical connection between the wire and the leaf spring, making the energizing structure of the leaf spring more stable, thereby extending the service life of the leaf spring and the mover.
[0031] Furthermore, in some embodiments of this disclosure, there are multiple threading members 304, which are spaced apart circumferentially along the fixing ring 303. Specifically, to ensure balanced force distribution, there are generally three threading members 304, and two wires are used. Both wires can be threaded through one threading member 304, or one wire can be threaded through one threading member 304.
[0032] Furthermore, in some embodiments of this disclosure, the first side of the threading member 304 is flush with the first side of the fixing ring 303 for attachment and fixation to the leaf spring. A groove 305 is provided on the second side of the threading member 304, recessed towards the first side of the threading member 304, with the bottom surface of the groove 305 lower than the second side of the fixing ring 303. Specifically, the thickness of the threading member 304 is equal to the thickness of the fixing ring 303. The first side of the threading member 304 is flush with the first side of the fixing ring 303, and the second side of the threading member 304 is flush with the second side of the fixing ring 303. Both the first side of the fixing ring 303 and the first side of the threading member 304 are attached and fixed to the leaf spring. The groove 305 is formed on the second side of the threading member, with the bottom of the groove 305 lower than the second side of the fixing ring 303, so that the wire can be accommodated in the groove 305 after passing through the threading member 304.
[0033] Furthermore, in some embodiments of this disclosure, the second side of the threading member 304 is flush with or protrudes from the second side of the fixing ring 303. Specifically, in use, the first side of the threading member 304 is in contact with the left leaf spring, and the second side of the threading member 304 is in contact with the right leaf spring. This increases the contact area between the conductive electrode and the leaf spring, thereby enhancing the stability of the connection structure between the leaf spring and the wire.
[0034] Furthermore, in some embodiments of this disclosure, the groove 305 is disposed adjacent to the outer circumferential surface of the fixing ring 303, and the groove 305 connects the wire threading portion 301 and the outer circumferential surface of the fixing ring 303. Specifically, after the wire passes through the wire threading portion 301, it can directly enter the groove 305 and extend from the groove 305 to the outer circumferential surface of the fixing ring 303 for fixation.
[0035] Furthermore, in some embodiments of this disclosure, the groove 305 is annular in shape, concentrically arranged with the fixing ring 303, and the inner sidewall of the groove 305 is formed on the outer circumferential surface of the fixing ring 303. This facilitates guiding the wire to the outer circumferential surface of the fixing ring 303.
[0036] Furthermore, such as Figure 1 and Figure 2 As shown, in some embodiments of this disclosure, the threading member 304 is annular, and the threading portion 301 is a threading hole provided on the threading member 304. The centers of the threading holes on the multiple threading members 304 are located on the same circle. Therefore, the multiple threading members 304 on the fixing ring 303 have universal applicability in use, and it is not necessary to fix the threading members 304 on the fixing ring 303 in a specific position. The function and role of each threading ring 304 are the same.
[0037] Furthermore, such as Figure 3 As shown, in some other embodiments of this disclosure, the threading member 304 includes two opposing arc-shaped locking blocks 304b, with a threading portion 301 formed between the two arc-shaped locking blocks 304b. That is, the threading member 304 may not be a regular closed ring structure; rather, it may be formed by two independent arc-shaped locking blocks 304b arranged opposite each other, with the wire passing through and fixed between the two arc-shaped locking blocks 304b.
[0038] Furthermore, such as Figure 4 As shown, in some other embodiments of this disclosure, the threading member 304 includes a hook 304c extending radially outward from the outer circumferential surface of the fixing ring 303, and a threading portion 301 is formed on the inner side of the hook 304c.
[0039] Of course, the form of the wire threading component 304 and the wire threading part 301 disclosed herein is not limited to the forms proposed in the above embodiments. As long as the wire threading box can fix the wire, it is feasible.
[0040] Furthermore, in some embodiments of this disclosure, a leaf spring assembly and a conductive electrode as described in any of the above embodiments are also provided. The leaf spring assembly includes multiple coaxially arranged leaf springs. One side of the conductive electrode is fitted and fixed to the leaf spring, and a fixing ring is correspondingly arranged with the inner fixing hole of the leaf spring. A through hole for the wire to pass through is provided on the leaf spring at a position corresponding to the wire hole. The wire is a coil wound on a coil frame. The wire extends from the coil frame into the through hole on the leaf spring, then passes through the wire-passing part on the wire-passing member, and contacts and is fixed to the outer circumferential surface of the fixing ring. Generally, the wire is fixed to the outer circumferential surface of the fixing ring by welding, which ensures the connection strength and electrically connects the wire, the conductive electrode, and the leaf spring. When the wire is energized, the conductive electrode conducts electricity, thereby energizing the leaf spring. The setting of the conductive electrode increases the contact area between the wire and the leaf spring, making the energized structure of the leaf spring more stable, thereby extending the service life of the leaf spring and the mover.
[0041] Furthermore, some embodiments of this disclosure also provide a linear motor, including the above-described energized leaf spring wire-threading structure.
[0042] Furthermore, this disclosure also provides a linear compressor, including the aforementioned linear motor.
[0043] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0044] The above description is merely a specific embodiment of this disclosure, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this disclosure.
