Description

Technical Field

[0001] This utility model provides a waterproof wire harness interface that can be quickly plugged in and unplugged, belonging to the technical field of line connection devices. Background Technology

[0002] In modern industrial equipment, wire harness interfaces have become key components ensuring the reliability and convenience of electrical connections. These interfaces typically consist of a male and a female connector, which are secured after insertion by friction or a simple snap-fit ​​mechanism, and are widely used in applications requiring frequent connection and disconnection. In scenarios involving high-altitude cabling, to facilitate operation and avoid dragging cables, a common connection method is to suspend one end of the connector (usually a female) from the equipment body or a high location via a cable, while the other end (the male) is inserted from the bottom up. This arrangement provides clear guidance during insertion and removal, simplifying the alignment process to some extent.

[0003] However, existing interface designs do not adequately consider the special working condition of "one end suspended, one end plugged in upwards," revealing two significant drawbacks. First, when disconnecting, the lower plug end, due to its cable drooping naturally and lacking effective support directly below, will fall directly to the ground or equipment platform under gravity. Oil, dust, water stains, and other contaminants on the ground easily adhere to the exposed connector pins or contacts, requiring tedious cleaning by operators before each connection and potentially causing poor contact, increased resistance, or even short circuits, seriously threatening electrical safety. Second, because the suspended plug end is relatively high, the falling male connector will bring its cable down with it, significantly increasing the distance between the male and female connectors. When reconnecting, operators must first bend down to pick up the male connector from the ground and raise it to the height of the suspended female connector for alignment. This process is time-consuming and laborious, greatly diminishing the advantage of "quick plugging and unplugging." Therefore, a new type of wire harness interface structure effectively addressing this working condition is urgently needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that when disconnecting, the lower plug end is often easily contaminated by water stains and dust, and the lower plug end is far from the upper plug end, which is not conducive to quick plugging.

[0005] To address the aforementioned problems, the proposed technical solution is as follows: a quick-plug waterproof wire harness interface, comprising a connecting wire, an electrical connecting block, and an electrical plug block, wherein the electrical connecting block is suspended below the connecting wire; the electrical connecting block has an electrical plug interface, and the electrical plug block is provided with an electrical connector capable of being inserted into the electrical plug interface; further comprising:

[0006] A protective cylinder; the protective cylinder with an opening at the lower end is fixedly sleeved on the electrical connector block, and the electrical connector block is located inside the protective cylinder; the inner wall of the protective cylinder is provided with an annular limiting groove, and the outer wall of the electrical connector block is fixedly connected with a limiting ring that slides up and down in the limiting groove; the upper and lower positioning magnets that can attract the limiting ring are respectively embedded and fixed on the upper and lower sides of the inner wall of the limiting groove.

[0007] As an improvement, an upper adsorption magnet capable of engaging with an upper positioning magnet is embedded and fixed on the upper surface of the limiting ring, and a lower adsorption magnet capable of engaging with a lower positioning magnet is embedded and fixed on the lower surface of the limiting ring.

[0008] As an improvement, the upper positioning magnet and the lower positioning magnet are annular rings corresponding to the limiting groove, and the upper adsorption magnet and the lower adsorption magnet are annular rings corresponding to the shapes of the upper positioning magnet and the lower positioning magnet.

[0009] As an improvement, waterproof sealing gaskets are provided at both the upper and lower ends of the limiting ring.

[0010] As an improvement, a sealing plate that can block the opening of the protective cylinder is fixedly connected below the electrical plug block, and a waterproof sealing gasket is provided on the sealing plate.

[0011] The beneficial effects of this utility model are:

[0012] 1. This application, by incorporating a protective sleeve on the electrical connector block, significantly enhances the sealing effect when the electrical connector block and the electrical plug block are connected, thereby improving waterproofing and dustproofing. When disconnecting, simply pull the electrical plug block downwards; the limiting ring will stop the plug block from detaching from the protective sleeve. At this time, the electrical plug block remains stably inside the protective sleeve and will not fall to the ground. Furthermore, when reconnection is required, simply push the electrical plug block upwards; the operator does not need to bend down to pick it up or reposition it, enabling quick reconnection.

[0013] 2. Waterproof sealing gaskets are provided at both the upper and lower ends of the limiting ring, which can ensure the sealing effect of the electrical plug interface and the electrical connector whether it is in the plugged-in or disconnected state, greatly increasing the dustproof and waterproof effect; the magnetic attraction structure can greatly increase the stability during plugging or the stability of the electrical plug block after separation.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] This utility model provides a waterproof wire harness interface that can be quickly plugged in and out: it includes a connecting wire 1, an electrical connecting block 3, and an electrical plug block 4. The electrical connecting block 3 is suspended below the connecting wire 1. An electrical plug interface 8 is provided inside the electrical connecting block 3, and an electrical plug connector 11 that can be inserted into the electrical plug interface 8 is provided on the electrical plug block 4.

[0022] As attached Figure 1 , 2 The protective cylinder 2 with an opening at the lower end is fixedly fitted onto the electrical connection block 3, and the electrical plug block 4 is located inside the protective cylinder 2. The electrical plug block 4 and the electrical connection block 3 are inserted into the protective cylinder 2. At the same time, a sealing plate 5 that can seal the opening of the protective cylinder 2 is fixedly connected below the electrical plug block 4, and a waterproof sealing gasket is provided on the sealing plate 5, which can greatly improve the overall waterproof effect.

[0023] As attached Figure 2 The inner wall of the protective cylinder 2 is provided with an annular limiting groove 7, and the outer wall of the electrical connector 4 is fixedly connected with a limiting ring 6 that slides up and down in the limiting groove 7; the setting of the limiting groove 7 can ensure that the electrical connector 4 will not separate from the protective cylinder 2 when the electrical connector 11 is pulled out; both the upper and lower ends of the limiting ring 6 are provided with waterproof sealing gaskets to improve the sealing effect on the electrical connector 11 and the electrical connector interface 8.

[0024] Upper positioning magnet 9 and lower positioning magnet 10, capable of attracting the limiting ring 6, are respectively embedded and fixed on the upper and lower sides of the inner wall of the limiting groove 7. Upper adsorption magnet 12, capable of engaging with the upper positioning magnet, is embedded and fixed on the upper surface of the limiting ring 6, and lower adsorption magnet 13, capable of engaging with the lower positioning magnet, is embedded and fixed on the lower surface of the limiting ring 6. The upper positioning magnet 9 and lower positioning magnet are annular rings corresponding to the limiting groove 7, and the upper adsorption magnet 12 and lower adsorption magnet 13 are annular rings corresponding to the shapes of the upper positioning magnet 9 and lower positioning magnet. This magnetic attraction structure greatly increases the stability during insertion and also increases the stability of the electrical connector 4 after separation, preventing mis-insertion.

[0025] The principle of this utility model

[0026] When connection is required, the operator simply lifts the electrical connector block 4 upwards with one hand using the sealing plate 5. The electrical connector block 4 causes the limiting ring 6 to slide upwards within the limiting groove 7 of the protective cylinder 2 until the upper adsorption magnet 12 on the limiting ring 6 engages with the upper positioning magnet 9 on the upper edge of the limiting groove 7. At this point, the electrical connector 11 on the electrical connector block 4 is precisely and stably inserted into the electrical connector interface 8 of the electrical connector block 3, achieving circuit connection. Simultaneously, the waterproof sealing gaskets at both ends of the limiting ring 6 ensure the sealing of the connection, and the sealing plate 5 seals the lower end of the protective cylinder 2, further increasing the sealing performance. The protective cylinder 2 then forms an external protective barrier.

[0027] When disconnection is required, in the attachment Figure 2 In this state, the operator pulls the electrical connector block 4 downwards using the sealing plate 5, overcoming the attraction of the upper positioning magnet 9. Under the influence of gravity and pulling force, the electrical connector block 4 slides down, and its limiting ring 6 moves downwards along the limiting groove 7 until it is firmly attracted by the lower positioning magnet at the lower edge of the limiting groove 7 and the lower adsorption magnet 13 on the limiting ring 6. During this process, the electrical connector 11 separates from the electrical interface 8. Finally, the electrical connector block 4 is suspended and stored inside the protective cylinder 2. Thanks to the waterproof sealing gasket on the limiting ring 6, the electrical connector 11 is isolated from the external environment, while the electrical connector block 4 will not fall to the ground or be contaminated by water or other pollutants. The electrical connector block 4 remains close to the electrical connection block 3 above, preparing for the next quick connection.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
