Description

Technical Field

[0001] This utility model relates to the field of energy storage connectors, and in particular to a flat male pin of an energy storage connector. Background Technology

[0002] Energy storage connectors, as key components for power transmission in energy storage systems, are widely used in new energy vehicles, energy storage power stations, portable energy storage devices, and other scenarios. Among them, the flat male pin, as the core conductive contact of the energy storage connector, plays a dual role in current conduction and structural positioning. Its material properties, surface treatment process, and sealing performance are crucial to the service life and reliability of the connector.

[0003] Traditional energy storage connectors typically use conventional copper alloys (such as brass and copper) as the base material for their flat male pins. While these materials possess good conductivity and can meet basic current transmission requirements, in long-term vibration environments (such as mechanical vibrations during vehicle operation or equipment running), the contact area between the male pin and the plug is prone to surface wear due to repeated friction. This not only increases contact resistance and affects conductivity, but in severe cases, structural damage can lead to poor contact or open circuit risks. Furthermore, the surface of traditional flat male pins is usually silver-plated. While the silver layer can improve conductivity and corrosion resistance to some extent, in humid, high-temperature, or sulfur-containing environments, the silver layer easily reacts chemically with sulfides in the air, forming a black silver sulfide film. This increases surface resistance, reduces contact performance, and consequently affects the overall operational stability of the connector. In addition, in the structural design of traditional energy storage connectors, when the socket and plug are inserted, the mating gap between them often relies on a single sealing ring for sealing. Under long-term use or vibration conditions, the sealing ring of this design is prone to sealing failure due to aging, deformation or uneven pressure, which allows impurities such as dust and moisture to enter the connector. This not only aggravates the corrosion and wear of the male pin and plug, but may also cause safety hazards such as short circuits. Therefore, its sealing performance needs to be further improved. Hence, this application proposes a flat male pin for an energy storage connector to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a flat male pin for an energy storage connector, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A flat male pin for an energy storage connector includes a male pin body. The male pin body has a three-layer structure, consisting of a beryllium copper alloy substrate, a nickel plating underlayer, and a gold plating layer from the inside out. The nickel plating underlayer is directly plated onto the surface of the beryllium copper alloy substrate, and the gold plating layer covers the nickel plating underlayer. A reinforcing sealing assembly is fixedly installed on the male pin body. The reinforcing sealing assembly consists of a support base ring, an arc-shaped spring, a conical spring, and a reinforcing sealing ring. Several arc-shaped springs are fixedly installed in a ring on the inner wall of the support base ring. The conical spring is fixedly installed at one end of the support base ring, and the reinforcing sealing ring is fixedly installed at one end of the conical spring.

[0007] Preferably, the male pin body is fixedly installed inside the socket housing, and a plug structure is inserted into the socket housing, which is also sleeved on the male pin body.

[0008] Preferably, the reinforcing sealing assembly is located inside the socket housing, and the reinforcing sealing assembly is also located on the side of the male pin body near the plug structure.

[0009] Preferably, the support base ring, conical spring, and reinforcing sealing ring on the reinforcing sealing assembly are all sleeved on the male needle body.

[0010] Preferably, the support base ring on the reinforced sealing assembly is fixedly fastened to the male pin body by a plurality of arc-shaped spring pieces fixedly installed on its inner wall, the conical spring is fixedly installed at one end of the support base ring near the plug structure, and the reinforced sealing ring is fixedly installed at one end of the conical spring near the plug structure.

[0011] Preferably, the conical spring and the reinforcing sealing ring on the reinforcing sealing assembly are movably sleeved on the male pin body, and the reinforcing sealing ring is tightly attached to the contact area between the plug structure and the socket shell under the elastic force of the conical spring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) By setting the male pin body composed of beryllium copper alloy substrate, nickel underlayer and gold plating, the beryllium copper alloy substrate has excellent elasticity and fatigue resistance, and can maintain a stable structural shape under long-term vibration environment, reducing poor contact caused by vibration; the nickel underlayer can enhance the bonding force between the substrate and the gold plating, effectively prevent the gold plating from falling off, and provide good anti-corrosion performance; the gold plating has excellent conductivity and oxidation resistance, which can reduce contact resistance, reduce surface wear, extend the service life of the male pin, and ensure the stability of current transmission.

[0014] (2) By setting a reinforced sealing assembly consisting of a support base ring, an arc-shaped spring, a conical spring, and a reinforced sealing ring on the male pin body, the support base ring is securely fastened to the male pin body by the arc-shaped spring, ensuring the reliability of the assembly installation. The conical spring can continuously provide elastic force, so that the reinforced sealing ring fits tightly against the contact part between the plug structure and the socket shell. Even if the component is slightly deformed due to vibration or temperature changes, it can maintain a good sealing effect, effectively blocking the intrusion of impurities such as dust and moisture, avoiding corrosion of internal components and short circuit risks, and significantly improving the sealing performance and working reliability of the connector.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a flat male pin of an energy storage connector includes a male pin body 1. The male pin body 1 has a three-layer structure, consisting of a beryllium copper alloy substrate 5, a nickel base layer 6, and a gold plating layer 7 from the inside out. The nickel base layer 6 is directly plated on the surface of the beryllium copper alloy substrate 5, and the gold plating layer 7 covers the nickel base layer 6. A reinforcing sealing assembly 4 is fixedly installed on the male pin body 1. The reinforcing sealing assembly 4 consists of a support base ring 8, an arc-shaped spring 9, a conical spring 10, and a reinforcing sealing ring 11. Several arc-shaped springs 9 are fixedly installed in a ring on the inner wall of the support base ring 8. The conical spring 10 is fixedly installed at one end of the support base ring 8, and the reinforcing sealing ring 11 is fixedly installed at one end of the conical spring 10. By setting the male pin body 1, which consists of a beryllium copper alloy substrate 5, a nickel base layer 6, and a gold plating layer 7, the beryllium copper alloy substrate 5 has excellent elasticity and fatigue resistance, and can maintain a stable structural shape under long-term vibration environment, reducing poor contact caused by vibration; nickel The underlayer 6 enhances the bonding between the substrate and the gold plating layer 7, effectively preventing the gold plating layer 7 from peeling off, while also providing good corrosion resistance. The gold plating layer 7 has excellent conductivity and oxidation resistance, which can reduce contact resistance, reduce surface wear, extend the service life of the male pin body 1, and ensure the stability of current transmission. By setting a reinforced sealing assembly 4 on the male pin body 1, consisting of a support base ring 8, an arc-shaped spring 9, a conical spring 10, and a reinforced sealing ring 11, the support base ring 8 is firmly fixed to the male pin body 1 by the arc-shaped spring 9, ensuring the reliability of the assembly installation. The conical spring 10 can continuously provide elastic force, so that the reinforced sealing ring 11 fits tightly against the contact area between the plug structure 3 and the socket housing 2. Even when vibration or temperature changes cause slight deformation of the components, a good sealing effect can be maintained, effectively preventing the intrusion of dust, moisture and other impurities, avoiding internal component corrosion and short circuit risks, and significantly improving the sealing performance and operational reliability of the connector.

[0023] Specifically, the male pin body 1 is fixedly installed inside the socket housing 2. A plug structure 3 is inserted into the socket housing 2, and the plug structure 3 is simultaneously fitted onto the male pin body 1. The reinforcing sealing assembly 4 is located inside the socket housing 2, and is also located on the side of the male pin body 1 closest to the plug structure 3. The supporting base ring 8, conical spring 10, and reinforcing sealing ring 11 on the reinforcing sealing assembly 4 are all fitted onto the male pin body 1. The supporting base ring 8 on the reinforcing sealing assembly 4 is fixedly secured to the male pin body 1 by several arc-shaped spring pieces 9 fixedly installed on its inner wall. The conical spring 10 is fixedly installed at one end of the supporting base ring 8 near the plug structure 3, and the reinforcing sealing ring 11 is fixedly installed at one end of the conical spring 10 near the plug structure 3. The conical spring 10 and the reinforcing sealing ring 11 on the reinforcing sealing assembly 4 are movably fitted onto the male pin body 1, and the reinforcing sealing ring 11 is tightly pressed against the contact area between the plug structure 3 and the socket housing 2 under the elastic force of the conical spring 10. The reinforcing sealing ring 11 is made of fluororubber. Made of fluororubber, which has excellent high and low temperature resistance, chemical corrosion resistance, and elastic recovery ability, it can maintain good sealing properties during long-term use and is not prone to aging and deterioration even when exposed to moisture, oil, etc., ensuring a tight fit with the contact parts of the plug structure 3 and the socket shell 2. The support base ring 8, arc-shaped spring 9, and conical spring 10 are made of phosphor bronze. Phosphor bronze has high strength, elasticity, and corrosion resistance. When the support base ring 8 is fixed to the male pin body 1 by the arc-shaped spring 9, the elasticity of the phosphor bronze allows the arc-shaped spring 9 to fit tightly against the surface of the male pin body 1, ensuring the stability of the installation and preventing loosening. The conical spring 10, made of phosphor bronze, can provide a stable and durable elastic force and is not prone to fatigue failure during long-term compression and rebound, ensuring that the reinforcing sealing ring 11 is always under continuous pressure to maintain the sealing effect. At the same time, the corrosion resistance of phosphor bronze can prevent these components from rusting in humid or corrosive environments, extending the overall service life of the reinforcing sealing assembly 4.

[0024] When the plug structure 3 is inserted into the socket housing 2 and the male pin body 1, the support base ring 8 in the reinforcing sealing assembly 4 is securely fastened to the male pin body 1 by several arc-shaped spring pieces 9 on its inner wall, ensuring that the overall position of the reinforcing sealing assembly 4 is fixed. At this time, the conical spring 10 fixedly installed at the end of the support base ring 8 near the plug structure 3 is compressed by the plug structure 3 and undergoes elastic deformation. Under the elastic reaction force of the conical spring 10, the reinforcing sealing ring 11 will be pushed to fit tightly against the contact part between the plug structure 3 and the socket housing 2. Since the conical spring 10 continuously provides elastic force, even if the plug structure 3, socket housing 2 and other components undergo slight deformation due to vibration or temperature changes, the reinforcing sealing ring 11 can still maintain a tight fit with the contact part, thereby effectively preventing dust, moisture and other impurities from entering the interior of the socket housing 2, ensuring the cleanliness and dryness of the contact part between the male pin body 1 and the plug structure 3, and maintaining a good sealing effect.

[0025] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
