Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, specifically a waterproof female-pin electrical connector. Background Technology

[0002] In the field of electrical connections, in scenarios such as outdoor equipment, automobiles, ships and industrial automation, equipment often faces environmental challenges such as rain and humidity. Traditional electrical connection devices are prone to short circuits, leakage or poor contact due to water ingress.

[0003] In existing technologies, protective shells are typically used to protect waterproof parts. However, when electrical connection parts heat up due to excessive contact resistance or overload, timely maintenance cannot be performed. Insulating materials degrade more rapidly at high temperatures, reducing insulation performance and increasing the risk of short circuits. Seals soften and deform at high temperatures, or harden and crack at low temperatures, damaging the waterproof structure and causing the protective shell to lose its waterproof effect. Therefore, we propose a waterproof female-male pin electrical connection device. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof female-to-male electrical connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof female-pin electrical connector, comprising a male pin body, a female pin body disposed on the male pin body, and further comprising:

[0006] The protective assembly includes a protective shell disposed on the female head body, wherein two protective shells are provided and a first rotating shaft is rotatably connected between the two protective shells;

[0007] A tactile component includes a fixing pin connected to the inner wall of a protective shell, a nickel-titanium alloy wire sleeved on the fixing pin, a drive plate connected to the nickel-titanium alloy wire, a support member provided on the inner wall of the protective shell, a second rotating shaft rotatably connected to the support member, the drive plate rotatably connected to the second rotating shaft, and a push rod connected to the drive plate.

[0008] Furthermore, a heat dissipation assembly is provided on the side of the protective shell near the push rod. The heat dissipation assembly includes a heat dissipation vent on the protective shell. A third rotating shaft is rotatably connected to the side of the protective shell near the heat dissipation vent, and a baffle is rotatably connected to the third rotating shaft.

[0009] The above technical solution involves setting up a heat dissipation component. When the sensing component detects that the internal temperature of the protective shell is too high, the heat dissipation component will work to dissipate the internal heat in a timely manner.

[0010] Furthermore, a spring clip is connected to the side of the male needle body near the baffle, and the side of the spring clip away from the protective shell is connected to the baffle.

[0011] The above technical solution is adopted: by setting a spring, when the internal temperature decreases, the nickel-titanium alloy wire returns to its original length, and the baffle automatically springs back to its original position by the elastic force of the spring.

[0012] Furthermore, the protective shell is provided with a quick-release assembly, which includes a fixing base. There are two fixing bases, each located on the top of one of the two protective shells, and a plug is inserted into the fixing base.

[0013] The above technical solution allows for quick installation and removal of the protective shell by setting up quick-release components, facilitating the maintenance of internal components.

[0014] Furthermore, a sealing ring is fitted on the side of the female head body near the male needle body, and the sealing ring is located at the connection between the male needle body and the female head body.

[0015] The above technical solution involves setting a sealing ring to fill and waterproof the gap between the male needle and the female head.

[0016] Furthermore, the female head body is provided with four scrapers, which are respectively located around the inner wall of the female head body, and the scrapers are arc-shaped.

[0017] The above technical solution is adopted: by setting a scraper, since the scraper is made of elastic material, when the male needle is inserted into the female head, the elastic scraper is squeezed and undergoes elastic deformation, and its cutting edge slides relative to the surface of the male needle, using friction to scrape, break and peel off the oxide layer.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] In this invention, by setting a sensing component, abnormal temperature can be monitored in real time. When the electrical connection heats up due to poor contact, overload, or other factors, it can react in time to provide heat dissipation components. This solves the problems in the prior art, where protective shells are usually used to protect waterproof parts. However, when the electrical connection parts heat up due to excessive contact resistance or overload, timely maintenance cannot be provided. Insulating materials degrade more rapidly at high temperatures, reducing insulation performance and increasing the risk of short circuits. Seals soften and deform at high temperatures, or harden and crack at low temperatures, damaging the waterproof structure and causing the protective shell to lose its waterproof effect.

[0032] 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.

[0033] like Figures 1-4 As shown, this utility model provides a technical solution: a waterproof female-pin electrical connector, including a male pin body 1, a female pin body 2 disposed on the male pin body 1, and further comprising:

[0034] The protective component 3 includes a protective shell 31 disposed on the female head body 2. There are two protective shells 31, and a first rotating shaft 32 is rotatably connected between the two protective shells 31.

[0035] The sensor component 4 includes a fixing pin 41 connected to the inner wall of the protective shell 31, a nickel-titanium alloy wire 42 sleeved on the fixing pin 41, a drive plate 43 connected to the nickel-titanium alloy wire 42, a support member 44 provided on the inner wall of the protective shell 31, a second rotating shaft 45 rotatably connected to the support member 44, the drive plate 43 rotatably connected to the second rotating shaft 45, and a push rod 46 connected to the drive plate 43.

[0036] A heat dissipation assembly 5 is provided on the side of the protective shell 31 near the push rod 46. The heat dissipation assembly 5 includes a heat dissipation port 51 opened on the protective shell 31. A third rotating shaft 53 is rotatably connected on the side of the protective shell 31 near the heat dissipation port 51. A baffle 52 is rotatably connected on the third rotating shaft 53.

[0037] Specifically, when the internal heat is too high, the nickel-titanium alloy wire 42 will bend due to the heat, thereby pulling the drive plate 43 to rotate through the second rotating shaft 45. The drive plate 43 drives the push rod 46 to move, and the push rod 46 will push the baffle 52 to rotate through the third rotating shaft 53, thereby allowing the heat dissipation port 51 to be exposed and the internal heat to be discharged in time, preventing short circuits of internal components.

[0038] Furthermore, such as Figure 4 As shown: A sealing ring 8 is fitted on the side of the female head body 2 near the male needle body 1. The sealing ring 8 is located at the connection between the male needle body 1 and the female head body 2. By setting the sealing ring 8, the gap between the male needle and the female head is filled and waterproofed.

[0039] The above solution also includes the requirement that when the internal temperature decreases, the baffle 52 should automatically reset to seal the heat dissipation vent 51. Figure 1 As shown: A spring piece 9 is connected to the side of the male needle body 1 near the baffle 52. The side of the spring piece 9 away from the protective shell 31 is connected to the baffle 52. When the internal temperature is too low, the nickel-titanium alloy wire 42 will return to its original position, thereby driving the drive plate 43 to rotate to its original position through the second rotating shaft 45. The drive plate 43 drives the push rod 46 to separate from the baffle 52. After the baffle 52 has not lost its support, it will automatically spring back to its original position by the elastic force of the spring piece 9.

[0040] The above solutions also require that the protective casing 31 be easily disassembled to facilitate the maintenance of internal components, such as... Figure 1 As shown: The protective shell 31 is provided with a quick-release assembly 6. The quick-release assembly 6 includes a fixing seat 61. There are two fixing seats 61, which are respectively located on the top of the two protective shells 31. A plug 62 is inserted into the fixing seat 61. After the plug 62 is separated from the fixing seat 61, the two protective shells 31 are rotated apart by the first rotating shaft 32.

[0041] Furthermore, such as Figure 5As shown: The female head body 2 is provided with a scraper 7. There are four scraper 7s and they are located around the inner wall of the female head body 2. The scraper 7 is arc-shaped. When the male needle is inserted into the female head, the elastic scraper 7 is squeezed and undergoes elastic deformation. Its cutting edge slides relative to the surface of the male needle. The oxide layer is scraped, broken and peeled off by friction.

[0042] The working principle provided by this utility model is as follows: Figures 1-5 As shown: First, the male needle is inserted into the female head. When the male needle is inserted into the female head, the elastic scraper 7 is compressed and undergoes elastic deformation. Its cutting edge slides relative to the surface of the male needle, using friction to scrape, break, and peel off the oxide layer. Then, the protective shells 31 are closed together and fixed by the insert block 62 and the fixing seat 61. Subsequently, when the internal temperature decreases, the baffle 52 should automatically reset to seal the heat dissipation vent 51. Figure 1 As shown: A spring piece 9 is connected to the side of the male needle body 1 near the baffle 52. The side of the spring piece 9 away from the protective shell 31 is connected to the baffle 52. When the internal temperature is too low, the nickel-titanium alloy wire 42 will return to its original position, thereby driving the drive plate 43 to rotate to its original position through the second rotating shaft 45. The drive plate 43 drives the push rod 46 to separate from the baffle 52. After the baffle 52 has not lost its support, it will automatically spring back to its original position by the elastic force of the spring piece 9. When the internal temperature is too low, the nickel-titanium alloy wire 42 will return to its original position, thereby driving the drive plate 43 to rotate to its original position through the second rotating shaft 45. The drive plate 43 drives the push rod 46 to separate from the baffle 52. After the baffle 52 has not lost its support, it will automatically spring back to its original position by the elastic force of the spring piece 9.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
