Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and particularly relates to a male head of a large-current connector. Background Art

[0002] The combination of the female head and the male head on an electric vehicle connector is a common connection method for connecting important components or devices of the electric vehicle to a power source or a battery. The female head usually refers to the part with a fixed interface, while the male head is the component that can be inserted into the female head interface. This design enables the battery and other parts of the electric vehicle to be quickly and conveniently connected and disconnected.

[0003] The female head of the electric vehicle is installed on the battery panel, and the male head is used to cooperate with the female head for plugging and power connection. In the traditional design, the male head is directly inserted into the female head without a waterproof sealing ring at the contact part, which may cause moisture to penetrate to the contact point. In a long-term humid environment, corrosion may occur, affecting the contact performance and even causing short circuit or circuit failure. In addition to the waterproof problem, the lack of a sealing ring also allows dust and other debris to enter the contact point, which may lead to poor contact or increased resistance.

[0004] In addition, for the male head with too large current in the traditional male head, the diameter of the thick needle is mostly 8.0 mm, and the end face of the thick needle of the male head is a copper end face. Copper is a good conductive material. If the end face is directly exposed, it may increase the risk of electric shock. Especially in a humid environment, if the copper end faces are in direct contact and there is no proper surface treatment or coating, it may increase the contact resistance, resulting in heat generation at the connection part, affecting the normal operation of electrical equipment and even causing thermal damage. When impacted or affected by external forces, the end face may be damaged, affecting the contact performance and even causing short circuit or open circuit. Summary of the Utility Model

[0005] The technical problem to be solved by the present invention is the poor waterproof and sealing performance of the contact part between the male head and the female head and the increased risk of electric shock caused by the direct exposure of the end face of the thick needle of the male head in the above-mentioned prior art.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] A male head of a large-current connector, comprising:

[0008] A male head housing, on the outer side surface of which a silicone waterproof ring A is sleeved for waterproofing the side surface of the female head of the large-current connector;

[0009] Male head pins, including two thick male head pins for passing large current and eight thin male head pins for passing signals, which are riveted on the male head housing. One end of each thick male head pin is provided with a step, and a plastic insulating part integrally formed with the thick male head pin is injection-molded on the outer side surface of the step.

[0010] Preferably, the diameter of the two male thick pins is 9.0 mm.

[0011] Preferably, the front end of the male housing has two insertion slots A for the two male thick pins to extend into and for sealing and plugging with the thick pin sheath on the female head of the high-current connector, and a waist-shaped insertion slot for the eight male thin pins to extend into and for sealing and plugging with the thin pin sheath on the female head of the high-current connector.

[0012] Preferably, the rear end of the male housing has an insertion slot B for the two male thick pins and the eight male thin pins to extend into. Inside the insertion slot B, there are bumps sleeved on the outer sides of the eight male thin pins and an outer sheath sleeved on the outer sides of the two male thick pins. Inside the insertion slot B, there is a partition strip separating the two outer sheaths and connected to the bottom of the bumps. The end of the male thick pin with a plastic insulating part extends into the insertion slot A.

[0013] Preferably, the top of the male housing has two L-shaped supports connected by a connecting strip, a limiting block arranged inside the two L-shaped supports, and a buckle for snap-connecting with the female head of the high-current connector. There is a pin connected to the buckle between the two L-shaped supports, and a spring is sleeved on the outer side of the pin and located between the L-shaped support and the buckle.

[0014] Preferably, a limiting groove for one end of the spring to be snapped into for limiting is reserved between the limiting block and the connecting strip.

[0015] Preferably, one end of the buckle is provided with an anti-slip rib for hand pressing, and the other end is provided with a buckle strip for snap-connecting with the clamping position on the female head of the high-current connector. The design of the anti-slip rib and the buckle strip makes the plugging and unplugging more convenient, improves the connection stability and reliability, and thus enhances the user experience.

[0016] The material selection (PPT material) and structural design (such as anti-slip ribs, buckles, etc.) of the male housing are all aimed at providing a more stable connection and preventing accidental detachment. In addition, the design of the spring and the pin provides additional stability and elasticity to ensure a firm connection.

[0017] Compared with the prior art, the technical effects and advantages of the present utility model are:

[0018] By arranging a silicone waterproof ring A at the contact between the male head and the female head of the high-current connector, this design effectively prevents moisture from penetrating to the contact point, improves the waterproof performance. This ensures that the connector can also maintain good performance in a humid environment, reducing the risks of corrosion and short circuit.

[0019] The design of the insertion slot A and the waist-shaped insertion slot, in cooperation with the plastic insulating parts on the male thick pins, not only provides good insulation performance but also reduces the possibility of dust and other sundries entering the contact point, ensuring the stability of the contact.

[0020] Using a male thick needle with a larger diameter (9.0 mm) provides a larger contact area, which helps to disperse the current, reduce the wear of the contact points, and thus can withstand a larger current without overheating easily. This design allows for the simultaneous transmission of large currents and signals, making it very suitable for devices such as electric vehicles that need to handle high power and communication simultaneously.

[0021] The plastic insulation on the male thick needle and the partition design in the insertion slot provide additional protection for the thick needle and the thin needle, reducing the risk of damage during insertion and removal.

[0022] Generally speaking, this design of the male connector for large currents represents a significant technological advancement compared to traditional designs in terms of improving the connection safety, reliability, and user experience of electric vehicles. Description of the Drawings

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] The following is combined with Figures 1-16 To further explain this application in detail,

[0043] like Figures 1-7As shown, an embodiment of the present application discloses a male connector 100 for a high-current connector, which is used to connect with a female connector 200 for a high-current connector, for example, used to connect with Figure 8 the female connector 200 for a high-current connector shown;

[0044] The male connector 100 for a high-current connector includes a male housing 11, two thick male pins 12 riveted on the male housing 11 and used for passing large currents, and eight thin male pins 13 used for passing signals; this design allows for simultaneous transmission of large currents and signals, and is very suitable for devices such as electric vehicles that require simultaneous processing of high power and communication;

[0045] The diameters of the two thick male pins 12 are 9.0 mm. Compared with the thick male pins 12 with a diameter of 8.0 mm, the larger-diameter pins will have a larger contact area, which helps to disperse the current during the welding process, reduce the wear of the contact points, and thus can withstand a larger current without causing the pins to overheat. As Figures 5-7 shown, one end of the thick male pin 12 is provided with a step 121 and a plastic insulating part 122 integrally formed with the thick male pin 12 is injection-molded on the outer side of the step 121; this helps to improve the insulation performance, reduce the risk of electric shock, and provide additional protection to prevent damage to the thick pins during insertion and extraction;

[0046] As Figures 1-4 shown, the front end of the male housing 11 has two insertion slots A102 for the two thick male pins 12 to extend into and for sealing and plugging with the thick pin sheaths 2106 on the female connector 200 for a high-current connector, and a waist-shaped insertion slot 103 for the eight thin male pins 13 to extend into and for sealing and plugging with the thin pin sheaths 2107 on the female connector 200 for a high-current connector. The rear end of the male housing 11 has an insertion slot B104 for the two thick male pins 12 and the eight thin male pins 13 to extend into. Inside the insertion slot B104, there are bumps 105 sleeved on the outer sides of the eight thin male pins 13 and outer sheaths 106 sleeved on the outer sides of the two thick male pins 12. Inside the insertion slot B104, there is a partition strip 107 that separates the two outer sheaths 106 and is connected to the bottom of the bump 105. The end of the thick male pin 12 with the plastic insulating part 122 extends into the insertion slot A102.

[0047] The front end of the male housing 11 has two insertion slots A102 and a waist-shaped insertion slot 103 to cooperate with the thick pin sheaths 2106 and thin pin sheaths 2107 on the female connector 200 for a high-current connector for sealing plugging. This design helps to achieve better plugging and unplugging stability and sealing performance, and prevent moisture and dust from entering the inside of the connector.

[0048] Inside the insertion slot B104, there is a partition strip 107 that separates the two outer sheaths 106 and is connected to the bottom of the bump 105. This helps to maintain the isolation between the outer sheaths 106 and prevent them from interfering with or colliding with each other during insertion and extraction.

[0049] The male housing 11 is injection-molded from PPT material. The PPT material has excellent mechanical properties, heat resistance, and electrical insulation, and can provide a long service life and reliable performance.

[0050] Specifically, as Figures 1-4 shown, the top of the male housing 11 has two L-shaped supports 108 connected by a connecting bar 109, a limiting block 110 provided inside the two L-shaped supports 108, and a buckle 14 for cooperating with the female head 200 of the high-current connector to be buckled. A pin 15 connected to the buckle 14 is provided between the two L-shaped supports 108. A spring 16 is sleeved on the outer side of the pin 15 and is located between the L-shaped support 108 and the buckle 14. A limiting groove 111 for cooperating with one end of the spring 16 to be snapped in for limiting is reserved between the limiting block 110 and the connecting bar 109;

[0051] One end of the buckle 14 is provided with an anti-slip convex strip 1401 for cooperating with manual pressing, and the other end is provided with a buckle strip 1402 for cooperating with the clamping position 2111 on the female head 200 of the high-current connector to be buckled; the buckle 14 helps to provide a stable connection and prevent accidental detachment of the connector during plugging and unplugging. The design of the pin 15 and the spring 16 helps to provide additional stability and elasticity, enabling the buckle 14 to be more tightly buckled with the female head 200 of the high-current connector. The design of the anti-slip convex strip 1401 and the buckle strip 1402 helps to improve the user experience, making plugging and unplugging more convenient, and at the same time ensuring the stability and reliability of the connection

[0052] The pin 15 is made of aluminum alloy material, and the spring 16 is made of spring 16 steel material. These materials have excellent mechanical properties and corrosion resistance, and can provide a long service life and reliable performance.

[0053] A silicone waterproof ring A101 is sleeved on the outer side of the male housing 11 for waterproofing the side of the female head 200 of the high-current connector. This helps to improve the waterproof performance, prevent moisture from penetrating into the connector interior, and protect the circuit from the influence of a humid environment.

[0054] Generally speaking, this design of the male head 100 of the high-current connector helps to improve the safety, reliability, and user experience of the electric vehicle. At the same time, by using appropriate materials and a well-designed structure, it can be ensured that the connector can maintain stable performance under various environments and usage conditions.

[0055] As Figures 8-16 shown, the embodiment of the present application also discloses a female head 200 of a high-current connector for connecting with the male head 100 of the high-current connector, for example, for connecting with Figure 1 the male head 100 of the high-current connector shown;

[0056] The female head 200 of the high-current connector is used to be installed on the battery panel. The female head 200 of the high-current connector includes a female head housing 21, two female head thick pins 22 riveted on the female head housing 21 and mating and plugging with two male head thick pins 12, and eight female head thin pins 23 mating and plugging with eight male head thin pins 13. Corresponding jacks are provided on the female head thick pins 22 and the female head thin pins 23, which can exactly match the male head thick pins 12 and the male head thin pins 13, so that the male head pins can be correctly inserted and form a stable connection. The combination of the female head thick pins 22 and the female head thin pins 23 can match the male head thick pins 12 and the male head thin pins 13, ensuring correct plugging and alignment, so as to form a stable and reliable electrical connection and reduce problems caused by poor contact.

[0057] Specifically, the female head housing 21 is provided with a clamping position 2111 that cooperates with and is buckled to the buckle 14 on the male head 100 of the high-current connector.

[0058] With such a setting, the design of the buckle 14 and the clamping position 2111 enables the female head and the male head to achieve a closer fit when connected, effectively preventing the connection from loosening due to vibration or impact, thereby enhancing the stability of the connection. The buckle 14 and the clamping position 2111 can achieve quick plugging and unplugging while ensuring the connection stability, improving the use efficiency and facilitating the operation of users.

[0059] Specifically, mounting holes 2102 are provided at the four corners of the female head housing 21, and metal cap covers 2103 are pressed into the mounting holes 2102. The metal cap covers 2103 are made by stainless steel stretching.

[0060] It can be understood that the setting of the mounting holes 2102 at the four corners of the female head housing 21 reduces the thickness of the female head housing 21 at the positions of the mounting holes 2102 at the four corners. When the male head 100 of the high-current connector and the female head 200 of the high-current connector are repeatedly plugged and unplugged, the positions of the mounting holes 2102 at the four corners of the female head housing 21 are prone to breakage. In addition, during the driving of the electric vehicle, the screws installed in the mounting holes 2102 of the female head housing 21 will loosen due to the vibration of the electric vehicle during driving. Installing the metal cap covers 2103 into the mounting holes 2102 makes the positions of the mounting holes 2102 at the four corners of the female head housing 21 not easily break when the male head 100 of the high-current connector and the female head 200 of the high-current connector are repeatedly plugged and unplugged. After the M4 screws fixing the female head housing 21 are installed into the metal cap covers 2103, they are not easily loosened.

[0061] With such a configuration, the stainless - steel material of the metal cap 2103 provides higher strength and corrosion resistance, enhancing the overall durability of the connector. The presence of the metal cap 2103 reduces the stress concentration on the female housing 21 during repeated plugging and unplugging, reducing the risk of fracture. The metal cap 2103 provides a more stable screw - fixing point, effectively preventing the screws from loosening during the operation of the electric vehicle and ensuring the stability of the connector.

[0062] Specifically, one end of the female housing 21 has a plug - in slot B2104 for mating with the male head of the high - current connector 100, and the other end has a plug - in slot C2105. The two ends of the two female thick pins 22 and the eight female thin pins 23 respectively extend into the plug - in slot B2104 and the plug - in slot C2105. In the plug - in slot B2104, there are two thick - pin sheaths 2106 sleeved on the outer sides of the two female thick pins 22 and one thin - pin sheath 2107 sleeved on the outer sides of the eight female thin pins 23. In the plug - in slot C2105, there is a T - shaped separator 2108 that separates the two female thick pins 22 and the eight female thin pins 23 from each other.

[0063] With such a configuration, the designs of the plug - in slot B2104 and the plug - in slot C2105 enable the female thick pins 22 and the female thin pins 23 to extend respectively and maintain sufficient stability and contact pressure during high - current transmission. The thick - pin sheaths 2106 in the plug - in slot B2104 and the T - shaped separator 2108 in the plug - in slot C2105 help to maintain the positioning of the pins, preventing pin displacement caused by vibration or other factors during use.

[0064] Specifically, on both sides of the front of the female housing 21, there are a positive - pole identification slot 2109 and a negative - pole identification slot 2110 for positive - and - negative - pole reminder respectively; on the back of the female housing 21 and on the side away from the positive - pole identification slot 2109 and the negative - pole identification slot 2110, there is a silica - gel waterproof ring B2101.

[0065] With such a configuration, the design of the positive - and - negative - pole identification slots 2110 helps users quickly identify the positive and negative poles of the battery, avoiding the risks caused by incorrect plugging, which enhances the safety during use; the silica - gel waterproof ring B2101 plays a role in waterproofing and moisture - proofing, improving the sealing performance at the contact between the female housing 21 and the battery panel, protecting the connector from the intrusion of moisture and dust, and enhancing the weather resistance and reliability of the connector, especially when used outdoors or in a humid environment.

[0066] Specifically, as Figures 12-13As shown in the figure, the female thick needle 22 is provided with a socket groove A2201 for mating and plugging with the male thick needle 12. A thick needle tube spring 2202 for increasing the pre-tightening force of the male thick needle 12 and the female thick needle 22 during insertion is placed in the socket groove A2201. The outer side surface of one end of the female thick needle 22 that mates and plugs with the male thick needle 12 is provided with a boss 2203, and the outer side surface of the boss 2203 is provided with a gland 2204 that mates, clamps, and presses with it to firmly limit the thick needle tube spring 2202 within the socket groove A2201, preventing the thick needle tube spring 2202 from falling out of the socket groove A2201;

[0067] With such a setting, the thick needle tube spring 2202 placed in the socket groove A2201 is used to increase the pre-tightening force of the male thick needle 12 and the female thick needle 22 during insertion, which helps to ensure the firmness of the connection. The gland 2204 of the thick needle tube spring 2202 is designed to firmly limit the thick needle tube spring 2202 within the socket groove A2201, preventing it from falling off, thereby enhancing the stability and reliability of the connection;

[0068] The outer side surface of one end of the female thick needle 22 that mates and plugs with the male thick needle 12 is provided with a boss 2203, and the outer side surface of the boss 2203 is provided with a gland 2204 that mates, clamps, and presses with it. This design helps to provide additional grip during the plugging and unplugging process, ensuring a tight connection between the male and female heads, and at the same time preventing the connection from loosening due to vibration or impact during use.

[0069] The elastic strips evenly distributed around the thick needle tube spring 2202 are inclined, which helps to provide a uniform force distribution when the male and female heads are plugged and unplugged, thereby reducing the frictional resistance during insertion and extraction and making the operation smoother.

[0070] The waist of the thick needle tube spring 2202 is designed with an inward constriction and the thick needle tube spring 2202 is formed by stamping beryllium copper; Beryllium copper alloy is selected for its good electrical conductivity and wear resistance, which helps to improve the electrical performance and durability of the connector. When the male thick needle 12 and the female thick needle 22 are inserted, due to the elasticity of the thick needle tube spring 2202 itself, the inward constriction of the waist of the thick needle tube spring 2202 contacts and tightens the female thick needle 22 within the thick needle tube spring 2202. To ensure that the male pin can be correctly and firmly inserted into the female pin and can protect the male pin from damage during the plugging and unplugging process. The waist of the thick needle tube spring 2202 is designed with an inward constriction, which helps to contact and tighten the female thick needle 22 within the thick needle tube spring 2202 when the male pin is inserted, thereby providing a more stable connection. The inward constriction contacts and positions around the male thick needle 12 in a circle, and has better stability compared to traditional point or small-area contact fixation.

[0071] Specifically, the female head housing 21 is injection-molded from PPT material. PPT (polymethyl acrylate) material has high strength and hardness, can withstand certain mechanical stresses and impacts, protect the internal components from damage. PPT material has excellent electrical insulation performance, can prevent current leakage, and ensure the electrical safety of the connector. PPT material has strong resistance to environmental factors such as temperature and humidity, and its performance will not be significantly affected by climate change.

[0072] Specifically, as Figures 14-15 shown, at one end where the female head fine pin 23 is inserted in cooperation with the male head fine pin 13, there is a necking portion 2301, and a fine pin tube spring 2302 is arranged inside the female head fine pin 23. The necking portion 2301 is used to position the fine pin tube spring 2302 inside the female head fine pin 23; the fine pin tube spring 2302 provides stable pressure to ensure good contact between the female head fine pin 23 and the male head fine pin 13, improving the reliability of the connection. The design of the necking portion 2301 helps to reduce dust and debris from entering the fine pin tube spring 2302, protects the cleanliness inside the connector and can limit the fine pin tube spring 2302, restricting the fine pin tube spring 2302 inside the female head fine pin 23.

[0073] In summary, the design of the high-current connector of the present application provides significant technological progress in improving safety, reliability, and user experience. At the same time, through careful selection of materials and design of the structure, it ensures that the connector can maintain stable performance under different environments and usage conditions.

[0074] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
