Description

Technical Field

[0001] This utility model relates to the field of waterproof electrical connector technology, and in particular to an electrical connector with waterproof function. Background Technology

[0002] Most existing electrical connectors use a single sealing structure, such as a rubber ring seal. After long-term use, they are prone to aging and deformation, leading to waterproof failure. This causes short circuits in the internal circuitry, which in turn damages electrical components. Of course, some waterproof connectors use multi-layer sealing or complex assembly processes, resulting in high costs and difficult installation. In other words, some waterproof connectors cannot simultaneously achieve a high waterproof rating and quick-connect / disconnect functionality. Utility Model Content

[0003] In order to overcome the shortcomings mentioned in the background art, the present invention provides an electrical connector with waterproof function.

[0004] The technical solution is: an electrical connector with waterproof function, including a female first insulator, a locking nut, and a male second insulator; a locking nut is installed on the male second insulator; the female first insulator is connected to the locking nut;

[0005] It also includes a conductive female needle, a female second insulator, a waterproof ring, a male first insulator, and a conductive male needle; the female second insulator is installed on the female first insulator and is screwed onto a locking nut; two symmetrically arranged conductive female needles are connected to the female second insulator; all conductive female needles are connected to the female first insulator; the male first insulator is installed on the female second insulator; two symmetrically arranged waterproof rings are installed inside the male first insulator; the waterproof rings are connected to the female second insulator; two symmetrically arranged conductive male needles are installed on the male first insulator and are connected to the male second insulator.

[0006] Furthermore, the first insulator at the female end and the second insulator at the female end are connected by a rotary locking structure.

[0007] Furthermore, the first male insulator and the second male insulator are connected by a rotary locking structure.

[0008] Furthermore, a waterproof material is provided on the surface of both the first insulator at the female end and the second insulator at the male end to form a seamless insulation layer.

[0009] Furthermore, an interface is provided on the second insulator at the female end, and a connector is provided on the first insulator at the male end, and an asymmetrical interface and connector structure is adopted.

[0010] Furthermore, each conductive female needle has a first gap between its right end and the right end of the second insulator, and the length of the first gap is 8mm-8.5mm. There is a second gap between two adjacent conductive female needles, and the length of the second gap is greater than 5mm. Beneficial effects

[0011] 1. This utility model combines rigid sealing and elastic sealing. When subjected to torsional pressure, the second insulator at the female end and the first insulator at the male end of the rigid sealing structure can withstand a large amount of pressure, thereby reducing the problem of deformation of the waterproof ring.

[0012] 2. This utility model uses an integrated injection molding process to wrap waterproof material around the first insulator at the female end and the second insulator at the male end, forming a seamless insulation layer. Compared with the traditional multi-layer sealing process, this injection molding process greatly reduces the manufacturing cost of this equipment.

[0013] 3. In the same process of using this utility model, the connection between the first insulator and the second insulator at the female end adopts a rotary locking structure, and the connection between the first insulator and the second insulator at the male end also adopts a rotary locking structure. After insertion, rotating at a certain angle triggers self-locking to prevent accidental detachment. Attached Figure Description

Detailed Implementation

[0019] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Example

[0021] A waterproof electrical connector, such as Figures 1-4 As shown, it includes a female end first insulator 1, a locking nut 7, and a male end second insulator 8; the locking nut 7 is installed on the male end second insulator 8; the female end first insulator 1 is connected to the locking nut 7;

[0022] It also includes a conductive female needle 2, a female end second insulator 3, a waterproof ring 4, a male end first insulator 5, and a conductive male needle 6; the female end second insulator 3 is installed on the female end first insulator 1, and the female end second insulator 3 is screwed to the locking nut 7; two symmetrically arranged conductive female needles 2 are connected to the female end second insulator 3; all conductive female needles 2 are connected to the female end first insulator 1; the male end first insulator 5 is installed on the female end second insulator 3; two symmetrically arranged waterproof rings 4 are installed inside the male end first insulator 5; the waterproof rings 4 are connected to the female end second insulator 3; two symmetrically arranged conductive male needles 6 are installed on the male end first insulator 5, and the conductive male needles 6 are connected to the male end second insulator 8.

[0023] The first insulator 1 and the second insulator 3 at the female end are connected by a rotary locking structure to prevent accidental detachment.

[0024] The male end first insulator 5 and the male end second insulator 8 are connected by a rotary locking structure to prevent accidental detachment.

[0025] Both the surface of the first insulator 1 at the female end and the second insulator 8 at the male end are provided with a layer of waterproof material to form a seamless insulation layer, which greatly reduces manufacturing costs while ensuring waterproof performance.

[0026] The female end second insulator 3 has an interface 3001, and the male end first insulator 5 has a connector 5001. The interface 3001 and connector 5001 are asymmetrical to avoid misinsertion that could damage the seal.

[0027] Each conductive female needle 2 has a first gap 001 between its right end and the right end of the second insulator 3, and the length of the first gap 001 is 8mm-8.5mm. There is a second gap 002 between two adjacent conductive female needles 2, and the length of the second gap 002 is greater than 5mm.

[0028] This equipment adopts a sealing method that combines the second insulator 3 at the female end, the waterproof ring 4, and the first insulator 5 at the male end, which is a combination of rigid and elastic sealing. This solves the problem of failure caused by aging or deformation of a single material. It should be noted that in use, such as in new energy vehicles, if only rubber rings are used for sealing, the wiring harness often needs to be adjusted during maintenance. As the connecting part of the wiring harness, the rubber ring is often subjected to torsional forces, which can lead to deformation and waterproofing failure. However, because this equipment adopts a combination of rigid and elastic sealing, when subjected to torsional forces, the rigid sealing structure of the second insulator 3 at the female end and the first insulator 5 at the male end can withstand a large amount of pressure, thereby reducing the problem of deformation of the waterproof ring 4.

[0029] Furthermore, since the first insulator 1 at the female end and the second insulator 8 at the male end of this equipment are both made using an integrated injection molding process, waterproof material is wrapped around the first insulator 1 at the female end and the second insulator 8 at the male end to form a seamless insulation layer. Compared with the traditional multi-layer sealing process, this injection molding process greatly reduces the manufacturing cost of this equipment.

[0030] Similarly, during the use of this equipment, the connection between the female first insulator 1 and the female second insulator 3 adopts a rotary locking structure, and the same applies to the male first insulator 5 and the male second insulator 8. After insertion, rotating at a certain angle triggers self-locking to prevent accidental dislodgement. After assembly in the above manner, it appears as follows: Figure 3 The state shown is the assembly after production. In subsequent use, it is only necessary to plug the two together and tighten the locking nut 7 to complete the assembly work during use. Since both the female end second insulator 3 and the male end first insulator 5 are provided with interface 3001 and connector 5001, and the interface 3001 and connector 5001 adopt an asymmetrical structure, it avoids damage to the female end second insulator 3, waterproof ring 4 and male end first insulator 5 due to mis-insertion. In other words, it realizes the function of quick assembly during use. Although the existing multi-layer sealed waterproof connector has higher waterproof performance than the single-seal structure, its assembly process is extremely complicated. The equipment shortens the assembly time while taking into account the waterproof performance, and effectively improves the assembly efficiency.

[0031] The length of the first gap 001 is set to 8mm-8.5mm, which extends the creepage distance between the conductive female pin 2 and the second insulator 3 at the female end. There is a second gap 002 between two adjacent conductive female pins 2, and the length of the second gap 002 is greater than 5mm, so that there is a sufficiently safe electrical clearance between two adjacent conductive female pins 2. This makes the device safer to use and enables the connection of high-voltage power supply to outdoor electrical equipment, thereby improving the safety of the device when it is used for power supply work outdoors.

[0032] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
