Description

Technical Field

[0001] This utility model belongs to the field of wiring harness technology, and in particular relates to a waterproof wiring harness for kitchen appliances. Background Technology

[0002] A kitchen wiring harness is an integrated electrical and cable assembly specifically designed to connect and distribute power and signals to various appliances in the kitchen. It typically includes multiple insulated wires, connectors (such as plugs and terminals), and necessary protective layers (such as corrugated tubing and braided mesh), safely and systematically transmitting power from the main distribution point (such as a socket, switch, or controller) to numerous devices such as refrigerators, ovens, dishwashers, range hoods, lighting fixtures, and small appliance sockets. Its core function is to simplify complex kitchen wiring, ensure a stable power supply, and, through proper bundling and protection design, improve the durability (resistance to high temperatures, humidity, and oily environments), safety (reducing the risk of short circuits and electric shock), and aesthetics (concealing messy cables). It is a key fundamental component for the efficient operation of modern kitchen electrical systems.

[0003] In the kitchen, the areas where wiring harnesses (including power cords, data cables, etc.) need waterproof protection are mainly concentrated near water sources, places that are prone to splashing water, moisture, or frequent cleaning, such as under and around the sink, around the dishwasher, and the connection points of instant water dispensers / water dispensers. To ensure waterproof performance, waterproof connectors are used at the connection points of the wiring harnesses.

[0004] Existing waterproof connectors use a male and female connector that fit together, with a sealing gasket between them, and are then tightened by threads. However, if there is water on the connector surface and the connector is pulled out, water will splash into the male or female connector, causing the conductor to rust.

[0005] To address the aforementioned issues, this application proposes a waterproof wiring harness for kitchen appliances. Utility Model Content

[0006] The purpose of this utility model is to provide a waterproof connection harness for kitchen appliances, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a waterproof wiring harness for kitchen appliances, comprising a first connector and a second connector connected to each other. The first connector has a female socket at its front end, and a conductive head is connected inside the female socket. A stop is provided at the outer end of the female socket. The second connector has a male head at its front end that plugs into the female socket. A conductive sleeve is provided inside the male head that plugs into the conductive head. A rotating waterproof plate is provided at one end of the male head near the first connector. A through hole with a diameter larger than that of the conductive sleeve is opened on the waterproof plate. A torsion spring is provided between the waterproof plate and the male head to keep the through hole and the conductive sleeve from being misaligned under normal conditions.

[0009] Furthermore, the waterproof membrane has an integrally formed adapter near the male end, and the front end of the male end has a movable groove for accommodating the adapter and the torsion spring.

[0010] Furthermore, each end of the torsion spring is provided with an insert rod at its eccentric position, the bottom of the movable groove is provided with an inner positioning groove for inserting the insert rod at one end of the torsion spring, and one end of the adapter is provided with an outer positioning groove for inserting the insert rod at the other end of the torsion spring.

[0011] Furthermore, the adapter has a groove on its outer side, a limiting ring is connected in the groove, the limiting ring is located in the groove and protrudes radially, and a limiting ring groove is provided on the inner side of the movable groove to cooperate with the protruding part of the limiting ring.

[0012] Furthermore, the male connector has a sealing groove at its front end located around the conductive sleeve, and a sealing gasket is embedded in the sealing groove. The outer side of the sealing gasket is in contact with the inner side of the waterproof plate.

[0013] Furthermore, a retaining ring is formed at the outer end of the male head, and a sealing ring that contacts the retaining ring is fitted onto the outside of the male head.

[0014] Furthermore, the male head is fitted with a threaded sleeve that slides axially at its outer rear end, and the inner side of the threaded sleeve is provided with a thread that mates with the outer side of the female head.

[0015] This utility model has the following beneficial effects:

[0016] This utility model provides a rotating waterproof plate at the front end of the male connector. The waterproof plate can form a barrier at the front end of the conductive sleeve when the connector is not connected. Even if water splashes when the male connector is removed, the water cannot directly contact the conductive sleeve, thus providing waterproof protection.

[0017] This invention incorporates a torsion spring between the No. 2 connector and the waterproof membrane. When the conductive head detaches from the through hole, the torsion spring automatically blocks the waterproof membrane at the front end of the No. 2 connector, preventing water from entering the conductive sleeve even if there is water outside the connector, thus ensuring a waterproof effect.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figures 1-5 As shown, this utility model is a waterproof connection harness for kitchen appliances, including a first connector 1 and a second connector 2 connected to each other. The first connector 1 has a female socket 11 at its front end, and a conductive head 12 is connected inside the female socket 11. The outer end of the female socket 11 has a stop seat 13. The second connector 2 has a male head 21 at its front end that is inserted into the female socket 11. The male head 21 has a conductive sleeve 211 inside that is inserted into the conductive head 12. The number of conductive heads 12 and conductive sleeves 211 is the same, and they are electrically conductive after insertion, for power and data transmission.

[0030] Specifically, the male connector 21 has a rotating waterproof plate 3 near the first connector 1. The waterproof plate 3 has a through hole 31 with a diameter larger than that of the conductive sleeve 211. A torsion spring 4 is provided between the waterproof plate 3 and the male connector 21 to keep the through hole 31 and the conductive sleeve 211 from being misaligned under normal conditions.

[0031] Specifically, the waterproof membrane 3 has an integrally formed adapter 32 near the male connector 21. The front end of the male connector 21 has a movable groove 212 for accommodating the adapter 32 and the torsion spring 4. The torsion spring 4 and the adapter 32 are hiddenly connected through the movable groove 212, so as to achieve elastic rotational engagement between the waterproof membrane 3 and the male connector 21.

[0032] Specifically, the torsion spring 4 has insert rods at both eccentric ends, and the bottom of the movable groove 212 has an inner positioning groove 213 for inserting the insert rod at one end of the torsion spring 4. The adapter 32 has an outer positioning groove 322 at one end for inserting the insert rod at the other end of the torsion spring 4. In this embodiment, the torsion spring 4 has inner and outer positioning grooves at both ends. When the waterproof plate 3 rotates, the rotational force can be directly transmitted to the torsion spring 4, thereby realizing manual power storage and automatic reset, so that the conductive sleeve 211 can obtain a more flexible waterproof effect.

[0033] Specifically, the adapter 32 has a groove 321 on its outer side, and a limiting ring 5 is connected in the groove 321. The limiting ring 5 is located in the groove 321 and protrudes radially. The movable groove 212 has a limiting ring groove 214 that mates with the protruding part of the limiting ring 5. In this embodiment, in order to prevent the limiting ring 5 from being stuck in the movable groove 212 when the waterproof membrane 3 is pulled out, the space of the limiting ring 5 in the groove 321 is larger than that in the limiting ring groove 214. Moreover, the limiting ring 5 can leave a certain gap in the limiting ring groove 214 without falling off, so as not to affect the normal rotation of the waterproof membrane 3.

[0034] To further enhance the waterproof effect of the conductive sleeve 211, a sealing groove 215 is provided at the front end of the male connector 21, located on the periphery of the conductive sleeve 211. A sealing gasket 6 is embedded in the sealing groove 215. The outer side of the sealing gasket 6 is in contact with the inner side of the waterproof plate 3. The sealing gasket 6 strengthens the sealing between the waterproof plate 3 and the male connector 21. In order not to affect the rotation of the waterproof plate 3, the sealing gasket 6 overlaps with the inner side of the waterproof plate 3.

[0035] Specifically, a retaining ring 22 is formed on the outer end of the male connector 21, and a sealing ring 8 that contacts the retaining ring 22 is fitted on the outside of the male connector 21. In this embodiment, after the first connector 1 and the second connector 2 are connected, the sealing ring 8 is pressed between the retaining ring 22 and the front end of the female connector 11, which is used for sealing the inside of the female connector 11 and the male connector 21.

[0036] Specifically, the male head 21 is also fitted with a threaded sleeve 7 that slides along the axial direction at its outer rear end. The inner side of the threaded sleeve 7 is provided with a thread that mates with the outer side of the female seat 11. In this embodiment, after the threaded sleeve 7 mates with the female seat 11, it axially presses the first connector 1 and the second connector 2 together.

[0037] It is understood that this utility model has a rotatable waterproof plate and its torsion spring at the front end of the male connector. When the connector is not connected, the torsion spring drives the waterproof plate to automatically rotate to the front end of the male connector to form a block, preventing external splash water from directly contacting the conductive sleeve and ensuring the waterproof effect.

[0038] One specific application of this embodiment is:

[0039] Assembly of waterproof membrane 3: Torsion spring 4 is placed inside movable groove 212 with one end placed in inner positioning groove 213, sealing gasket 6 is placed in sealing groove 215, limiting ring 5 is placed in ring groove 321, outer positioning groove 322 is aligned with the other end of torsion spring 4, adapter 32 is pressed into movable groove 212, limiting ring 5 enters limiting ring groove 214, outer side of sealing gasket 6 contacts inner side of waterproof membrane 3, torsion spring 4 is in reset state in this state, and through hole 31 is offset from conductive sleeve 211 at this time;

[0040] Connector connection: The sealing ring 8 is fitted over the male connector 21 and contacts the retaining ring 22. Hold connector 1 and connector 2 respectively, insert the conductive head 12 into the through hole 31, rotate connector 2, the torsion spring 4 is compressed, and while rotating, connector 2 is pushed forward. When the through hole 31 is coaxial with the conductive sleeve 211, the conductive head 12 is inserted into the conductive sleeve 211. After insertion, the threaded sleeve 7 slides and rotates towards one end of connector 1. The threaded sleeve 7 and the female seat 11 are spirally connected and press the connection between connector 1 and connector 2. The sealing ring 8 is also compressed, and the connector connection is completed.

[0041] When the connector is connected, Figure 1-2As shown, at this time, the through hole 31 is coaxial with the conductive sleeve 211, the conductive head 12 passes through the through hole 31 and is inserted into the conductive sleeve 211, the torsion spring 4 is in a compressed state, and the threaded sleeve 7 is spirally outside the female seat 11 and presses the sealing ring 8 to seal.

[0042] Disconnection of the connector: Unscrew the threaded sleeve 7 from the outside of the female seat 11, pull the male head 21 outward from the female seat 11, and disconnect the conductive head 12 from the conductive sleeve 211 and the through hole 31. At this time, the waterproof plate 3 will automatically rotate under the action of the torsion spring 4, so that the through hole 31 and the conductive sleeve 211 are misaligned, and the disconnection can be completed.
