Description

Technical Field

[0001] This utility model relates to the field of waterproof connector technology, specifically a waterproof female connector with a snap hook. Background Technology

[0002] With the rapid development of the new energy vehicle industry, vehicles often face complex environments such as rain and muddy roads during operation, which puts forward stringent requirements on the reliability and safety of the battery connection system. As the core component of the battery connection system, the waterproof performance of the connector directly affects the electrical safety and service life of the entire vehicle. Once the connector fails to be waterproof, moisture and dust can easily enter, which can easily cause faults such as short circuits and poor contact, seriously threatening driving safety. Currently, most battery connectors on the market use simple waterproof rubber rings as a waterproof sealing structure. While this method can provide some waterproofing, the sealing performance of the rubber ring depends on the initial pre-tightening force during installation. With the vibration and temperature changes generated during long-term vehicle operation, the rubber ring is prone to loosening and deformation, leading to an increase in the sealing gap and a gradual decrease in waterproofing performance, making it difficult to guarantee long-term reliable waterproofing of the connector. Furthermore, traditional waterproof rubber rings are of fixed specifications. When fitting the waterproof rubber ring onto the ring edge of the female connector, manual force is required to stretch and widen the gap to ensure proper insertion and accurate positioning. This stretching operation is strenuous, and excessive stretching of the waterproof rubber ring can affect its tightness when fitted onto the female connector. Therefore, a waterproof female connector with a snap hook is needed to solve the problems existing in the current technology. Utility Model Content

[0003] The purpose of this utility model is to provide a waterproof female connector with a snap hook to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a waterproof female connector with a snap hook, comprising: A connector for electrical connection between a male and a female connector; A plastic body, which is sleeved and fixed to the outside of the connector; A sleeve, which is fixed to the front port of the plastic part body; A sealing mechanism, which is sleeved on the outside of the sleeve, is used to seal the joint between the male and female seats; An inflation fine-tuning mechanism is fixed on the sealing mechanism and is used to adjust the inflation saturation of the sealing mechanism.

[0005] Preferably, the sealing mechanism includes a sealing airbag, which is sleeved on the outside of the sleeve. The inner ring wall of the sealing airbag is provided with an anti-detachment groove, and the outer ring surface of the sleeve is fixed with an anti-detachment post. The anti-detachment groove and the anti-detachment post are adapted to each other.

[0006] Preferably, the outer circumference of the sealing airbag is provided with a receiving groove, and the inflation fine-tuning mechanism includes a piston sleeve, which is fixed in the receiving groove of the sealing airbag, and a piston head is slidably connected inside the piston sleeve.

[0007] Preferably, an adjusting screw seat is fixed to one end face of the piston sleeve, and an adjusting screw rod is connected to the internal thread of the adjusting screw seat. One end of the adjusting screw rod, which extends into the piston sleeve, is fixed to the piston head.

[0008] Preferably, an inflation nozzle is fixed between the piston sleeve and the sealing airbag, and the piston sleeve, the inflation nozzle, and the sealing airbag are connected together.

[0009] Preferably, a sealing ring is fixed to the inner end wall of the piston sleeve, and the adjusting screw passes through the sealing ring.

[0010] Preferably, the upper and lower ends of the plastic part body are fixed with buckles.

[0011] Preferably, two needles are fixedly inserted into the front end face of the plastic part body, and the two needles are located on both sides of the connector.

[0012] This utility model provides a waterproof connector with a snap hook, which has the following advantages compared with the prior art: With the sealing mechanism in place, when the male and female seats mate, the sealing airbag initially fits the seam. At this time, the initial saturation of the sealing airbag is moderate, which results in a better stretching effect of the sealing airbag. This makes it easy to expand the diameter of the sealing airbag to easily fit it onto the sleeve. The position of the sealing airbag can also be adjusted on the sleeve to ensure accurate positioning of the anti-loosening groove and anti-loosening post, thereby ensuring the anti-loosening effect of the sealing airbag during sealing use.

[0013] Through the established sealing and inflation fine-tuning mechanisms, the inflated sealing airbag further tightens its fit against the joint between the male and female seats, enhancing sealing performance and effectively preventing moisture and dust from entering, thus providing excellent sealing protection. This inflation fine-tuning method allows for flexible adjustment of the airbag's inflation saturation according to actual usage scenarios and needs, ensuring optimal waterproof sealing under various conditions. Compared to the traditional method of using simple waterproof rubber rings, this adaptive fine-tuning sealing airbag inflation method, which tightly fits the joint, offers better adaptability and avoids the problem of traditional simple waterproof rubber rings becoming loose and deformed over long-term use, leading to a decline in waterproof performance.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-7 This utility model provides a waterproof female connector with a snap hook, comprising: Connector 17 is used for electrical connection between the male and female connectors; Plastic body 1, plastic body 1 is sleeved and fixed on the outside of connector 17; Sleeve 4 is fixed to the front port of the plastic body 1; The sealing mechanism 5 is sleeved on the outside of the sleeve 4. The sealing mechanism 5 is used to seal the joint between the male and female seats. The sealing mechanism 5 includes a sealing airbag 7, which is sleeved on the outside of the sleeve 4. The inner ring wall of the sealing airbag 7 is provided with an anti-detachment groove 9. The outer ring surface of the sleeve 4 is fixed with an anti-detachment post 10. The anti-detachment groove 9 and the anti-detachment post 10 are adapted to each other. The adjusting screw 13 drives the piston head 15 to slide inside the piston sleeve 11. The air inlet 14 fixed between the piston sleeve 11 and the sealing air bladder 7 connects the piston sleeve 11, the air inlet 14 and the sealing air bladder 7. As the piston head 15 slides, air is injected into the sealing air bladder 7 through the air inlet 14, causing the sealing air bladder 7 to expand and further tighten the fit between the male and female seats to enhance the sealing performance, effectively prevent moisture and dust from entering, and play a good sealing and protective role.

[0018] The inflation fine-tuning mechanism 6 is fixed on the sealing mechanism 5. The inflation fine-tuning mechanism 6 is used to adjust the inflation saturation of the sealing mechanism 5. The outer ring surface of the sealing airbag 7 is provided with a receiving groove 8. The inflation fine-tuning mechanism 6 includes a piston sleeve 11, which is fixed in the receiving groove 8 of the sealing airbag 7. A piston head 15 is slidably connected inside the piston sleeve 11. This inflation fine-tuning method allows for flexible adjustment of the inflation saturation of the sealing airbag 7 according to actual usage scenarios and needs, ensuring optimal waterproof sealing performance under different working conditions. Compared to the traditional method of simply using waterproof rubber rings to provide waterproofing, this adaptive fine-tuning sealing airbag 7 has better adaptability by tightly fitting the joint, avoiding the problem of loosening and deformation caused by long-term use of traditional simple waterproof rubber rings, which leads to a decrease in waterproof performance.

[0019] It is worth noting that one end face of the piston sleeve 11 is fixed with an adjusting screw seat 12, and the adjusting screw seat 12 is internally threaded with an adjusting screw 13. One end of the adjusting screw 13 extends into the piston sleeve 11 and is fixed on the piston head 15. An inflation nozzle 14 is fixed between the piston sleeve 11 and the sealing airbag 7. The piston sleeve 11, the inflation nozzle 14, and the sealing airbag 7 are connected. When the male and female seats are mated, the sealing airbag 7 initially fits the mating seam. At this time, the initial state of the sealing airbag 7 is generally saturated, so the stretching effect of the sealing airbag 7 is better. This makes it easier to expand the diameter of the sealing airbag 7 to easily fit onto the sleeve 4. The position of the sealing airbag 7 can be adjusted on the sleeve 4 so that the anti-loosening groove 9 and the anti-loosening post 10 are accurately positioned, thereby ensuring the anti-loosening effect of the sealing airbag 7 during sealing use.

[0020] It is worth noting that a sealing ring 16 is fixed to the inner end wall of the piston sleeve 11, and the adjusting screw 13 passes through the sealing ring 16. The sealing ring 16 fixed to the inner end wall of the piston sleeve 11 can prevent air leakage at the adjusting screw 13 and ensure the inflation effect.

[0021] It is worth noting that the upper and lower ends of the plastic body 1 are fixed with buckles 2, and two needles 3 are fixed through the front end face of the plastic body 1, and the two needles 3 are located on both sides of the connector 17.

[0022] The purpose of this solution is to provide a waterproof female connector with a snap hook, which has the following working process: In the battery connection system of new energy vehicles, due to the complex environment such as rain and mud encountered when the vehicle is in motion, the waterproof performance requirements of the battery connector are extremely high. This waterproof female connector with a snap hook can effectively ensure the stable connection and waterproof effect of the male connector. Its working principle is as follows: During installation, the plastic body 1 is fitted and fixed to the outside of the connector 17 for electrical connection with the male socket. The buckles 2 at the upper and lower ends of the plastic body 1 can quickly snap and fix it to the male socket. The sleeve 4 is fixed to the front port of the plastic body 1 to prepare for the subsequent assembly and sealing of the sealing mechanism 5.

[0023] When the sealing mechanism 5 is used on the outside of the sleeve 4, the anti-detachment groove 9 of the inner ring wall of the sealing airbag 7 is adapted to the anti-detachment post 10 on the outer ring surface of the sleeve 4, so that the sealing airbag 7 is fitted on the sleeve 4. When the male and female seats are mated, the sealing airbag 7 initially fits the mating seam. At this time, the initial state of the sealing airbag 7 is generally saturated, so the stretching effect of the sealing airbag 7 is better. It is convenient to expand the diameter of the sealing airbag 7 to easily fit it on the sleeve 4. The position of the sealing airbag 7 can be adjusted on the sleeve 4 so that the anti-detachment groove 9 and the anti-detachment post 10 are accurately positioned, thereby ensuring the anti-loosening effect of the sealing airbag 7 during sealing use.

[0024] After the male and female seats are docked, the inflation fine-tuning mechanism 6 can further enhance the sealing effect. The piston head 15 inside the piston sleeve 11 can be adjusted by the adjusting screw 13. Rotating the adjusting screw 13 causes the piston head 15 to slide inside the piston sleeve 11 because the adjusting screw seat 12 is threadedly connected to the adjusting screw 13. The inflation nozzle 14 fixed between the piston sleeve 11 and the sealing airbag 7 connects the piston sleeve 11, the inflation nozzle 14, and the sealing airbag 7. As the piston head 15 slides, air is injected into the sealing airbag 7 through the inflation nozzle 14, causing the sealing airbag 7 to inflate. The expansion further tightens the seal between the male and female seats to enhance sealing performance, effectively preventing moisture and dust from entering and providing excellent sealing protection. Through this inflation fine-tuning method, the inflation saturation of the sealing airbag 7 can be flexibly adjusted according to actual usage scenarios and needs, ensuring the best waterproof sealing effect under different working conditions. Compared with the traditional simple method of using waterproof rubber rings to provide waterproofing, this adaptive fine-tuning sealing airbag 7 has better adaptability by tightening the seal between the seats, avoiding the problem of loosening and deformation of traditional simple waterproof rubber rings after long-term use, which would cause a decrease in waterproofing performance.
