Description

Technical Field

[0001] This application relates to the field of conductor protection technology, and in particular to a conductor protection structure for an electronic expansion valve coil. Background Technology

[0002] In today's electronic equipment and other fields, coils are widely used as key components, and their quality and reliability directly affect the stability and lifespan of the equipment. Conventional coils typically use multiple wires connected to the power supply or control system. However, in actual use, the roots of the coil (especially the part where the wires connect to the casing) are prone to breakage or exposed copper wires due to mechanical stress, environmental temperature changes (such as low winter temperatures), and vibration. This not only affects the electrical performance of the coil but may also lead to equipment malfunctions or safety hazards. Therefore, there is an urgent need for a wire protection structure applicable to electronic expansion valve coils to solve these problems. Utility Model Content

[0003] To address the problems mentioned in the background art regarding the easy breakage of wires connected to existing coils and the exposure of copper wires, this application provides a wire protection structure for an electronic expansion valve coil.

[0004] The wire protection structure for an electronic expansion valve coil provided in this application adopts the following technical solution:

[0005] A wire protection structure for an electronic expansion valve coil includes a housing mounted on the coil, with an outwardly extending protective plate on one side wall of the housing; a wire harness is connected to the coil, and a wire sleeve is fitted around the wire harness and the protective plate; a locking member for connecting the wire harness and the protective plate is provided on the outside of the protective plate.

[0006] By adopting the above technical solution, an outwardly extending protective plate structure is set on one side of the traditional housing. This protective plate structure can fix the wire harness to the protective plate, so that the wire harness can maintain structural stability at the wiring end and avoid the problem of wire harness breakage due to mechanical stress, ambient temperature or vibration. Furthermore, since the protective plate is located on the outside of the wire harness, the problem of exposed copper wires can be avoided, which is beneficial to improving safety.

[0007] Optionally, the protective plate is integrally formed with the outer shell.

[0008] By adopting the above technical solution, the protective plate can be formed at the same time as the outer shell, which can not only improve the stability of the connection structure between the two, but also reduce the product manufacturing cost.

[0009] Optionally, the connection between the guard plate and the outer shell is chamfered.

[0010] By adopting the above technical solution, the wiring terminals of the wire harness can be shielded by the chamfered structure, avoiding the direct exposure of copper wires. Furthermore, the chamfer between the protective plate and the outer shell improves the stability of the connection structure between the protective plate and the outer shell, preventing the protective plate from easily breaking or being damaged, and extending its service life.

[0011] Optionally, the guard plate has a structure that is narrow in the middle and wide at the ends.

[0012] By adopting the above technical solution, the locking component can be conveniently locked in the middle position of the protective plate to prevent the locking component from falling off the protective plate, thus achieving the effect of connection and fastening.

[0013] Optionally, the inner wall of the guard plate is provided with a limiting groove along its length.

[0014] By adopting the above technical solution, the wire harness can be placed in the limiting groove, which to a certain extent plays a structural limiting role, preventing the wire harness from being placed outside the protective plate, and enabling the wire harness to achieve a good fixing effect.

[0015] Optionally, the locking element is a cable tie.

[0016] By adopting the above technical solution, we can achieve the advantages of low price, easy availability and easy operation, which is conducive to the rapid binding of wire harnesses and protective plates.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] This utility model features an outwardly extending protective plate structure on one side of a conventional housing. This protective plate structure can fix the wire harness to the protective plate, ensuring structural stability at the connection end and preventing wire harness breakage due to mechanical stress, ambient temperature, or vibration. Furthermore, since the protective plate is located on the outside of the wire harness, it avoids the problem of exposed copper wires, thus improving safety. Attached Figure Description

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] As shown in the figure, this application discloses a wire protection structure for an electronic expansion valve coil, including a housing 1 mounted on the coil 6. The housing 1 can be the outer shell of the electronic expansion valve coil 6. Multiple wire harnesses 3 are connected to the contacts of the coil 6. After the wiring is completed, the other end of the wire harnesses 3 extends from inside the housing 1 to outside the housing 1.

[0026] The outer casing 1 has an outwardly extending protective plate 2 on one side wall. The extension direction of the protective plate 2 is consistent with the outward extension direction of the wire harness 3, and the side wall of the outer casing 1 with the protective plate 2 is closer to the side wall of the wire harness 3. The coil 6 is connected to the wire harness 3, and the wire harness 3 and the protective plate 2 are fitted with a wire sleeve 5. A locking member for connecting the wire harness 3 and the protective plate 2 is provided on the outside of the protective plate 2.

[0027] Specifically, the protective plate 2 is integrally formed with the outer shell 1. The protective plate 2 and the outer shell 1 can be integrally injection molded, or, in other embodiments, the protective plate 2 is fixed to the outer shell 1 by bolt connection, which is not limited here.

[0028] Specifically, a chamfer 201 is provided at the connection between the protective plate 2 and the outer shell 1. The chamfer 201 can further shield the internal area of ​​the outer shell 1 to prevent the copper wires of the terminal from being exposed. The chamfer 201 can also increase the stability of the connection structure between the protective plate 2 and the outer shell 1, and prevent the protective plate 2 from being easily damaged.

[0029] Specifically, the guard plate 2 has a structure that is narrow in the middle and wide at the ends. For example, the guard plate 2 has a T-shaped structure, which mainly uses the wide size structure at the ends to prevent the locking parts from falling off.

[0030] Specifically, the inner wall of the guard plate 2 is provided with a limiting groove 202 along its length. In this example, there are two limiting grooves 202. In other embodiments, the limiting grooves 202 can be designed in different numbers. The wire harness 3 can be limited by the limiting grooves 202.

[0031] Specifically, the sleeve 5 is wrapped around the outside of the wire harness 3, and one end of the sleeve 5 wraps around the protective plate 2. The sleeve 5 is a heat shrink tubing, which can be used to initially fix the wire harness 3 to the protective plate 2.

[0032] Specifically, in this example, the locking component is a cable tie 4. Other components similar to ropes can also be used to fix the wire harness 3 to the guard plate 2, which can prevent the wire harness 3 from easily shaking.

[0033] In this type of electronic expansion valve coil protection structure, after the wiring harness 3 is completed, all the wiring harnesses 3 are first bundled together with the wire sleeve 5, and the wire sleeve 5 is placed on the outside of the protective plate 2 to achieve initial fixation of the wiring harnesses 3. Then, the locking device is used to fix the wiring harnesses 3 to the protective plate 2, so that the position of the wiring harness 3 near the coil end is fixed, avoiding the problem of the wiring harness 3 easily shaking or shifting at this position, avoiding the problem of wire breakage or copper wire exposure at this position, improving safety and extending the service life of the wiring harness 3.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
