Description

Technical Field

[0001] This utility model relates to the field of wire harness connector technology, and in particular to a waterproof electronic wire harness connector. Background Technology

[0002] In modern electronic equipment applications, from power systems of new energy vehicles and outdoor lighting equipment to marine exploration instruments and underwater robots, electronic wire harness connectors, as key components for achieving electrical connections, directly affect the operational stability of the entire system due to their reliability. Especially in environments with high humidity and easy contact with moisture, the waterproof performance of electronic wire harness connectors becomes a core element in ensuring the normal operation of equipment.

[0003] If the waterproof performance is insufficient, moisture intrusion can lead to oxidation and short circuits in the internal metal terminals of the connector, causing equipment malfunctions and even serious safety accidents. Most common electronic wire harness connectors on the market use sealing rings and sealants to achieve waterproofing. However, during long-term use, sealing rings and sealants are prone to aging and deformation due to factors such as changes in ambient temperature and mechanical vibration, resulting in a decline in sealing performance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing sealing rings and sealants, which are prone to aging and deformation due to environmental temperature changes and mechanical vibrations during long-term use, leading to a decline in sealing performance. This invention proposes a waterproof electronic wire harness connector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waterproof electronic wire harness connector includes a connector base and a connector. The connector base has a slot on its front side. The connector has a plug that matches the slot on its front side. The plug has a mounting groove at one end near the connector. A waterproof gasket is fitted on the mounting groove. The connector base is provided with a double-layer waterproof locking mechanism. The connector base is connected to the connector through the double-layer waterproof locking mechanism.

[0007] Preferably, the connector has a wire on its back side and an arc-shaped copper plate on its front side, the arc-shaped copper plate being connected to the wire.

[0008] Preferably, an external wiring is provided on the back of the connector, and a straight copper plate is fixedly provided deep inside the slot. The external wiring passes through the outer wall of the connector and is connected to the straight copper plate.

[0009] Preferably, the two-layer waterproof locking mechanism includes a rotating seat, a vertical connecting plate, a horizontal connecting plate, a buckle, a waterproof groove, and a limiting groove. The rotating seat is fixedly disposed around the outer wall of the connecting seat. The vertical connecting plate is rotatably disposed on the rotating seat. The horizontal connecting plate is rotatably disposed on the rotating seat. The buckle is fixedly disposed on the side of the vertical connecting plate and the horizontal connecting plate facing the connector.

[0010] Preferably, the slot has a stepped groove at its opening, which is adapted to the waterproof pad.

[0011] Preferably, the horizontal connecting plate has arc-shaped grooves at both ends, and the vertical connecting plate has semi-arc blocks fixedly installed at both ends. The semi-arc blocks are adapted to the arc-shaped grooves and are made of waterproof rubber material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In use, this utility model utilizes the adaptive design of the waterproof pad and the stepped groove. When the plug is inserted into the connector, the waterproof pad tightly fills the stepped groove, forming the first waterproof barrier and effectively preventing moisture from entering through the contact gap between the plug and the slot. Simultaneously, the waterproof groove in the second-layer waterproof locking mechanism further enhances the waterproof effect. When the connector and connector are locked together by the snap-fit, the waterproof groove prevents moisture from seeping along the connection. This dual waterproof structure works synergistically, significantly reducing the risk of decreased sealing performance due to changes in ambient temperature or mechanical vibration compared to traditional sealing rings and sealants, ensuring a consistently good waterproof seal during long-term use.

[0014] 2. In use, the rotating seat, vertical connecting plate, and horizontal connecting plate in the two-layer waterproof locking mechanism work together to securely lock the connecting seat and the connector together. The arc-shaped grooves at both ends of the horizontal connecting plate match the semi-arc blocks at both ends of the vertical connecting plate, which not only enhances the stability of the locking structure but also buffers the impact of mechanical vibration on the connection part to a certain extent. This stable connection method effectively avoids loosening of the connection due to vibration, ensures that the electronic wire harness connector can work stably in complex environments, and extends the service life of the product.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-4 A waterproof electronic wire harness connector includes a connector base 1 and a connector 2. The connector base 1 has a slot 3 on its front side. The connector 2 has a plug 4 that is compatible with the slot 3 fixedly installed on its front side. The plug 4 has a mounting groove 5 near the end of the connector 2. A waterproof pad 6 is fitted on the mounting groove 5. The connector base 1 is provided with a double waterproof locking mechanism 7. The connector base 1 is connected to the connector 2 through the double waterproof locking mechanism 7.

[0022] Both the connector 1 and the connector 2 are made of high-temperature nylon, which has the advantages of high temperature resistance and waterproofing. The connection methods for fixing the above-mentioned components are welding or integral molding.

[0023] Furthermore, a wire 8 is provided on the back of the connector 2, and an arc-shaped copper piece 9 is provided on the front of the plug 4, which is connected to the wire 8.

[0024] Among them, the arc-shaped copper sheet 9 is made of elastic copper alloy material to ensure close contact with the straight copper sheet 11 during insertion and removal, thereby reducing contact resistance and improving conductivity stability.

[0025] Furthermore, an external wiring 10 is provided on the back of the connector 1, and a straight copper plate 11 is fixedly provided deep inside the slot 3. The external wiring 10 passes through the outer wall of the connector 1 and is connected to the straight copper plate 11.

[0026] Among them, the straight copper sheet 11 is treated with gold plating process to enhance its oxidation resistance and ensure its electrical conductivity reliability during long-term use.

[0027] Furthermore, the second-layer waterproof locking mechanism 7 includes a rotating seat 12, a vertical connecting plate 13, a horizontal connecting plate 14, a buckle 15, a waterproof groove 16, and a limiting groove 17. The rotating seat 12 is fixedly disposed around the outer wall of the connecting seat 1. The vertical connecting plate 13 is rotatably disposed on the rotating seat 12. The horizontal connecting plate 14 is rotatably disposed on the rotating seat 12. The buckle 15 is fixedly disposed on the side of the vertical connecting plate 13 and the horizontal connecting plate 14 facing the connector 2.

[0028] Among them, buckle 15 is made of high-strength nylon material, which has excellent wear resistance and impact resistance, ensuring that it will stay locked for a long time without loosening.

[0029] Furthermore, a stepped groove 18 is provided at the opening of the slot 3, which is compatible with the waterproof pad 6.

[0030] Among them, the waterproof pad 6 is made of silicone rubber, which has excellent high and low temperature resistance (-40℃~200℃) and can effectively prevent moisture, dust and other substances from entering the slot 3.

[0031] Furthermore, the horizontal connecting plate 14 has arc-shaped grooves 19 at both ends, and the vertical connecting plate 13 has semi-arc blocks 20 fixedly installed at both ends. The semi-arc blocks 20 are adapted to the arc-shaped grooves 19 and are made of waterproof rubber material.

[0032] Among them, the semi-circular block 20 is made of EPDM rubber (ethylene propylene diene monomer rubber), which has excellent aging resistance and waterproof sealing effect, ensuring that the connector 2 can work stably for a long time in a humid environment.

[0033] Working principle:

[0034] First, align the plug 4 of connector 2 with the slot 3 of connector 1, aligning the curved copper piece 9 at the front end of plug 4 with the straight copper piece 11 inside slot 3. Upon insertion, the waterproof pad 6 deforms under pressure, tightly fitting the stepped groove 18 to form the first layer of waterproof barrier. Once plug 4 is fully inserted, the curved copper piece 9 and the straight copper piece 11 make elastic contact, ensuring circuit continuity.

[0035] Next, operate the second-layer waterproof locking mechanism 7: flip the vertical connecting plate 13 and the horizontal connecting plate 14 around the rotating seat 12 towards the connector 2, and the buckle 15 engages with the limiting groove 17 on the side of the connector 2. At this time, the arc-shaped groove 19 of the horizontal connecting plate 14 fits into the semi-arc block 20 of the vertical connecting plate 13, forming an annular sealing structure, which constitutes the second layer of waterproof barrier. The EPDM rubber material of the semi-arc block 20 further prevents water vapor from entering.

[0036] During disassembly, flip the vertical connecting plate 13 and the horizontal connecting plate 14 in reverse to release the locking of the buckle 15 and the limiting groove 17, and then pull out the connector 2. After the plug 4 is pulled out, the waterproof pad 6 returns to its original state, and the residual water stains in the stepped groove 18 are drained through the drainage design.

[0037] The entire process utilizes a dual waterproof design (waterproof pad 6 + semi-circular block 20) ​​and an elastic conductive structure (arc copper sheet 9 + straight copper sheet 11) to ensure that connector 2 operates stably in high-temperature and humid environments, with convenient insertion and removal and reliable sealing.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
