Technical Field
[0001] This utility model relates to the field of terminal plug technology, and more specifically, to a new energy copper-aluminum combined terminal plug. Background Technology
[0002] Terminal plugs, also known as terminal connector plugs, are core basic components in electronic circuits and electrical systems used to realize the transmission of electrical energy / signal and the detachable connection of components. Essentially, they use a plug-in structure with male and female plugs to allow two or more independent circuits / devices to form a stable path, while also taking into account the convenience of installation, maintenance and replacement.
[0003] However, existing terminal blocks have the following problems when used:
[0004] Traditional terminal blocks mostly use a single metal material. If all copper is used, although the conductivity is good, the cost is high. If all aluminum is used, the cost is low, but the conductivity is difficult to meet the high requirements. At the same time, existing terminal blocks often have problems such as insufficient connection stability, short insertion and removal life, and complex assembly process, which cannot well adapt to the comprehensive requirements of new energy equipment for low loss, high reliability and economy.
[0005] This utility model reduces costs and optimizes welding through a reasonable combination of copper and aluminum materials. It also ensures stable terminal plug-in connections and long service life through the cooperation of multiple structures, while simplifying the assembly process and meeting the requirements of reliability and economy in power transmission. Utility Model Content
[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a new energy copper-aluminum combined terminal plug.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a new energy copper-aluminum combined terminal plug, comprising: a copper-aluminum female pin, a copper-aluminum male pin, and a torsion spring. The copper-aluminum female pin consists of a female pin body and an auxiliary handle one. The copper-aluminum male pin consists of a male pin body and an auxiliary handle two. Both the female pin body and the male pin body are made of copper. Both the auxiliary handle one and the auxiliary handle two are made of aluminum. The torsion spring is embedded inside the female pin body.
[0008] A further preferred embodiment: an annular groove is formed on the left side of the outer surface of the mother needle body, and the annular groove is adapted to the torsion spring.
[0009] A further preferred embodiment: the mother needle body has an embedded cavity inside, the embedded cavity being composed of a bottom cavity and a receiving cavity.
[0010] A further preferred embodiment: the bottom cavity is located at the right end inside the mother needle body, the receiving cavity is located at the left end of the bottom cavity, and the diameter and width of the bottom cavity are smaller than those of the receiving cavity, and the torsion spring is embedded inside the receiving cavity.
[0011] A further preferred embodiment: the torsion spring is composed of a ring body one, a ring body two, and a contact spring, with the ring body one and the ring body two respectively fixedly installed at the left and right ends of the contact spring.
[0012] A further preferred embodiment: both the second annular body and the contact spring are embedded inside the accommodating cavity, and the first annular body forms a groove with the surface of the contact spring and is nested on the surface of the annular groove.
[0013] A further preferred embodiment: the right end of the annular body is fitted to the left end of the bottom cavity and is limited by the bottom cavity.
[0014] A further preferred embodiment: the auxiliary grip one and auxiliary grip two are arranged in a cylindrical and / or cuboid shape.
[0015] Beneficial effects:
[0016] 1. By incorporating auxiliary grip one and auxiliary grip two, both made of aluminum, which is cheaper than copper, production costs can be reduced effectively. Aluminum also has a lower melting point, making it easier to weld with other components and forming a stronger connection, thus improving the overall stability of the terminal plug structure. In terms of shape, they can be cylindrical or cuboid. The cylindrical shape is conducive to the adaptation with cylindrical components such as female and male pins, ensuring stable assembly; the cuboid shape increases the contact area with external tools or mounting structures, making operation and installation more convenient. At the same time, the copper female and male pin bodies achieve good conductivity, while the aluminum auxiliary grips optimize the mechanical properties and production economy of the structure while ensuring conductivity.
[0017] 2. The structure, which includes an annular groove, a bottom cavity, a receiving cavity, annular body one, and annular body two, provides a precise installation space for the torsion spring. This effectively limits the torsion spring's position, ensuring its stability within the female pin and preventing displacement. The annular groove and annular body one are matched to further fix the torsion spring, ensuring it maintains a good position during operation. This guarantees that when the male pin is inserted, the torsion spring can make stable contact with the male pin through its own elasticity, achieving reliable current conduction. The cooperation of annular body one and annular body two makes the torsion spring structure more stable, allowing it to continuously exert its elastic effect during repeated insertion and removal of the male pin, improving the service life and connection stability of the terminal plug. It also optimizes the assembly process, making the installation of the torsion spring more convenient and precise.
[0018] 3. By incorporating a female pin body and a male pin body, both made of copper, the terminal plug's excellent conductivity ensures efficient and stable transmission of current and other signals, providing reliable power conduction. Furthermore, copper's physical properties allow for stable contact with components such as torsion springs, achieving low-resistance, low-loss power transfer. This meets the high requirements of the new energy sector for power transmission efficiency and stability, ensuring the reliable performance of the terminal plug in power connections.
[0019] 4. In summary, this new energy copper-aluminum combined terminal plug, through the design of a female pin body, a male pin body, an auxiliary grip, an annular groove, a bottom cavity, a receiving cavity, and a torsion spring, utilizes copper to ensure efficient and stable current transmission by leveraging copper's excellent conductivity. The auxiliary grip is made of aluminum, which is low in cost and has a low melting point, reducing costs and facilitating welding, allowing for a strong connection with other components. The annular groove, bottom cavity, and receiving cavity provide precise installation and limiting space for the torsion spring. Annular body one and annular body two make the torsion spring structure more stable, ensuring that when the male pin is inserted, the torsion spring can make stable contact with the male pin through elasticity, ensuring reliable current conduction. This also improves the service life and connection stability of the terminal plug, optimizes the assembly process, and makes the torsion spring installation more convenient and precise.

Detailed Implementation
[0027] The following will refer to the appendix in the embodiments of this utility model. Figures 1-6 The technical solutions in the embodiments of this utility model will be clearly and completely described.
[0028] Please see Figure 1-6 In this embodiment of the utility model, a new energy copper-aluminum combined terminal plug includes: a copper-aluminum female pin 1, a copper-aluminum male pin 2, and a torsion spring 3. The copper-aluminum female pin 1 is composed of a female pin body 101 and an auxiliary handle 102. The copper-aluminum male pin 2 is composed of a male pin body 201 and an auxiliary handle 202. Both the female pin body 101 and the male pin body 201 are made of copper, and both the auxiliary handle 102 and the auxiliary handle 202 are made of aluminum. The torsion spring 3 is embedded inside the female pin body 101. An annular groove 103 is formed on the left side of the outer surface of the female pin body 101. The annular groove 103 is adapted to the torsion spring 3. The torsion spring 3 is composed of an annular body 301 and an annular body 302. 02. The contact spring 303 is composed of two ring bodies: a first ring body 301 and a second ring body 302, which are fixedly installed at the left and right ends of the contact spring 303, respectively. Both the second ring body 302 and the contact spring 303 are embedded inside the receiving cavity 106. The first ring body 301 forms a groove with the surface of the contact spring 303 and is nested in the annular groove 103. When the plug-in connection is performed, the male needle body 201 of the copper-aluminum male needle 2 is inserted into the female needle body 101 of the copper-aluminum female needle 1. The second ring body 302 of the torsion spring 3 and the contact spring 303 are embedded in the receiving cavity 106 of the female needle body 101. The first ring body 301 is nested on the outer surface of the female needle body 101. On the annular groove 103, the position of the torsion spring 3 within the female needle body is ensured to be stable. During the insertion of the male needle body 201, it will contact the contact spring 303 of the torsion spring 3. The torsion spring 3 utilizes its own elasticity to form a stable and good electrical contact between the male needle body 201 and the female needle body 101, thereby realizing the conduction of current, etc. Meanwhile, the auxiliary grip 1 102 and auxiliary grip 202 are made of aluminum, which, while ensuring a certain mechanical grip performance, takes advantage of the lightweight properties of aluminum. The female needle body 101 and the male needle body 201 are made of copper, which, with its excellent conductivity, gives the entire terminal plug both good conductivity and... The structural components make reasonable use of the respective properties of copper and aluminum. Copper has excellent electrical conductivity, so using copper for the female pin body 101 and male pin body 201 ensures efficient and stable transmission of signals such as current. Aluminum has a lower melting point, which makes it easier for the aluminum auxiliary grips 102 and 202 to form a strong connection with other components in welding and other processes, ensuring better welding quality. At the same time, aluminum is cheaper than copper. Using aluminum to make the auxiliary grips can effectively reduce the overall production cost of the terminal plug-in. While ensuring product performance, it achieves optimized cost control, combining practicality and economy.
[0029] In this embodiment of the present invention, an embedded cavity 104 is provided inside the female needle body 101. The embedded cavity 104 consists of a bottom cavity 105 and a receiving cavity 106. The bottom cavity 105 is located at the right end inside the female needle body 101, and the receiving cavity 106 is located at the left end of the bottom cavity 105. The diameter and width of the bottom cavity 105 are smaller than those of the receiving cavity 106. The torsion spring 3 is embedded inside the receiving cavity 106. The right end of the annular body 302 is attached to the left end of the bottom cavity 105 and is limited by the bottom cavity 105. When the male needle body 201 of the copper-aluminum male needle 2 is inserted into the embedded cavity 104 of the copper-aluminum female needle 1, the male needle body 201 first contacts the contact spring 303 and other parts of the torsion spring 3. Due to the annular body 302 of the torsion spring 3, the male needle body 201 first contacts the contact spring 303 and other parts of the torsion spring 3. 2. The right end is attached to the left end of the bottom cavity 105 and is limited by the bottom cavity 105. The position of the torsion spring 3 is relatively fixed in the accommodating cavity 106. During the insertion of the male pin body, the contact spring 303 of the torsion spring 3 will be squeezed. The torsion spring 3 uses its own elasticity to generate a reverse force, so that a stable electrical contact is formed between the male pin body 201 and the female pin body 101, thereby realizing the conduction of current. At the same time, the copper material of the female pin body 101 and the male pin body 201 ensures good conductivity, while the aluminum material of the auxiliary grip plays a role in mechanical grip and other aspects. Combined with the elastic contact of the torsion spring 3 and the limitation of the bottom cavity 105, the entire terminal plug can transmit electrical energy stably and reliably.
[0030] In this embodiment of the invention, the auxiliary grip 102 and the auxiliary grip 202 are cylindrical and / or cuboid in shape. The cylindrical shape facilitates the assembly of the female needle body 101, male needle body 201, and other cylindrical components with other cylindrical parts, providing better wrapping or fitting and ensuring connection stability. The cuboid shape is advantageous in scenarios requiring planar contact, installation, or gripping, increasing the contact area with external tools or mounting structures and improving operation. In terms of ease of use and stability, the cuboid can be set in two ways: one is in the middle of the left and right ends of the terminal, and the other is at the bottom of the left and right ends of the terminal. When it is in the middle of the left and right ends of the terminal, the grip force is more even, which makes it easier to apply force when inserting and removing the terminal. It is compatible with most common tools and improves the ease of operation. When it is at the bottom, the overall center of gravity of the terminal is lowered, which enhances the stability after installation. It is especially suitable for vertical or inclined installation scenarios and reduces loosening caused by external force. Both methods can flexibly adapt to different assembly environments and operational needs.
