[0001] This invention relates to the field of connectors, and in particular to a waterproof battery connector. Background Technology

[0002] Connectors are crucial carriers of data and power exchange, and their waterproof performance directly impacts product functionality and lifespan. With the rapid development of modern society and continuous technological advancements, people are increasingly concerned about the safety of various electronic products, and the quality and functional requirements of these products are also rising. As the carrier of data and power exchange between devices, machines, and other equipment, the importance of connectors is self-evident. Waterproofing has become a fundamental element of quality for an increasing number of electronic products, especially for connectors that carry wired data and power transmissions; their waterproof quality directly affects product functionality and lifespan. Furthermore, with the diversification and complexity of application environments for various electronic products, connectors with strong waterproof capabilities will be used in various fields worldwide, such as security, communications, industry, aerospace, marine, and military. Therefore, improvements in waterproofing technology will provide more reliable protection for equipment and machinery, making the use of electronic devices and machinery safer.

[0003] Most connectors on the market currently achieve waterproofing by using waterproof rings, but this typically only provides waterproofing to the connector's mating ends. When external moisture enters the connector, it can easily seep into the device it's connected to, potentially causing damage. Therefore, it's necessary to improve existing waterproof connectors. Summary of the Invention

[0004] In view of this, the present invention addresses the deficiencies of the prior art, and its main objective is to provide a waterproof battery connector that effectively solves the problem that existing waterproof connectors only provide waterproof performance at the connector's insertion end, and cannot prevent external moisture from entering the device to which the connector belongs after it has entered the connector.

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

[0006] A waterproof battery connector includes an insulating body, a power terminal, a signal terminal, a first waterproof ring, and a waterproof component.

[0007] The front end face of the insulating body is provided with a slot and an annular slot. The bottom end face of the slot extends forward to form a plug-in part. The plug-in part is provided with a power plug-in cavity and a signal plug-in cavity. The rear end face of the insulating body is provided with a waterproof groove, which is connected to the power plug-in cavity and the signal plug-in cavity.

[0008] The power terminal is embedded in the power plug cavity. The power terminal includes a power contact part, a power body part and a power crimping part integrally formed and connected from front to back. The power contact part and the power body part are both located in the power plug cavity. The power crimping part extends rearward from the power plug cavity to the outside of the waterproof groove.

[0009] The signal terminal is embedded in the signal plug cavity. The signal terminal includes a signal contact part, a signal body part and a signal crimping part integrally formed and connected from front to back. The signal contact part and the signal body part are both located in the signal plug cavity. The signal crimping part extends rearward from the signal plug cavity to the outside of the waterproof groove.

[0010] The first waterproof ring is embedded in the annular groove; the waterproof component is formed in the waterproof groove by potting glue, and the waterproof component covers the periphery of the local power crimping part and the periphery of the local signal crimping part.

[0011] As a preferred embodiment, the top surface of the waterproof groove is provided with a first boss and a second boss. The first boss has a first slot, and the aforementioned power crimping part extends rearward from the top surface of the first slot to the outside of the waterproof groove. The second boss has a second slot, and the aforementioned signal crimping part extends rearward from the top surface of the second slot to the outside of the waterproof groove. This design can increase the creepage distance and improve the voltage withstand performance of the connector during use.

[0012] As a preferred embodiment, a second waterproof ring is fitted onto the power supply body, which is in close contact with the inner wall of the power supply socket cavity, and a third waterproof ring is fitted onto the signal body, which is in close contact with the inner wall of the signal socket cavity, thereby further increasing the waterproof performance of the connector.

[0013] As a preferred embodiment, the power connector cavity is provided with a first protrusion, and a first anti-reverse ring is sleeved on the power contact portion. The first anti-reverse ring has a first anti-reverse portion, which is matched with the first protrusion for limiting engagement. The signal connector cavity is provided with a second protrusion, and a second anti-reverse ring is sleeved on the signal contact portion. The second anti-reverse ring has a second anti-reverse portion, which is matched with the second protrusion for limiting engagement. This makes the assembly of the terminal and the connector cavity more secure and reliable.

[0014] As a preferred embodiment, the power contact portion has a power contact cavity, and a first crown spring is disposed within the power contact cavity. The first crown spring contacts the inner wall of the power contact cavity. The signal contact portion has a signal contact cavity, and a second crown spring is disposed within the signal contact cavity. The second crown spring contacts the inner wall of the signal contact cavity. This design makes the contact between the terminals of the external connector and the terminals of this connector more stable and reliable, and provides more contact points, which is more conducive to the passage of current.

[0015] As a preferred embodiment, the front end face of the insulating body is provided with a fixing hole, and a threaded component is embedded in the fixing hole. The threaded component has a screw hole. The design of the screw hole allows the connector to be locked with the external mechanism by screws and is not easy to loosen. Moreover, by setting the threaded component in the fixing hole, it can be disassembled multiple times. If the fixing hole is not set with a threaded component, the plastic will be damaged after several screw removals.

[0016] As a preferred embodiment, the first waterproof ring has an H-shaped cross-section.

[0017] As a preferred embodiment, the plug portion is provided with a foolproof groove to prevent mis-plugging when the two connectors are plugged in.

[0018] As a preferred embodiment, the plug-in portion includes a first plug-in insulating body and a second plug-in insulating body, both of which are arranged in a slot. The aforementioned power plug-in cavity is formed on the first plug-in insulating body, the aforementioned signal plug-in cavity is formed on the second plug-in insulating body, and the aforementioned anti-fooling groove is formed on the second plug-in insulating body.

[0019] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0020] By creating a groove on the front end face of the insulating body and a waterproof groove on the rear end face of the insulating body, and then embedding a first waterproof ring in the annular groove, the waterproof component is molded into the waterproof groove by potting glue. The waterproof component covers the periphery of the local power crimping part and the periphery of the local signal crimping part. The first waterproof ring provides waterproof performance for the connector's plug end, preventing external moisture from entering the power plug cavity and signal plug cavity. When external moisture enters the power plug cavity or signal plug cavity, the waterproof component effectively prevents external moisture from entering the equipment to which the connector belongs.
