[0037] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manner of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0038] In the description of the present application, it should be understood that the terms "center", "length", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0039] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0040] In the present application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. It can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0041] In this application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature has a lower horizontal height than the second feature.

[0042] With the development of the new energy electric vehicle industry, the use of the electrical connector 100 in the whole vehicle is also increasing. Among them, since the space inside the whole vehicle for accommodating circuits is relatively narrow, in order to avoid problems such as space conflict caused by direct extension of cables, heat concentration in a certain area, and insufficient mechanical strength of circuit cables, the electrical connector 100 often needs to be 90° transferred. Therefore, it is a market demand to design a terminal that can achieve 90° transfer of the electrical connector. Currently, the transfer method of the electrical connector 100 is usually a two-piece structure, including a mating connector and a cable connector. The axial two ends of the mating connector are respectively provided with a mating insertion part and a mating transfer part, and both are female ends. The axis of the mating insertion part is perpendicular to the axis of the mating transfer part. The cable connector is a male end, and a wire pressing hole is provided at the tail of the cable connector. During use, the cable connector is inserted into the mating transfer part of the mating connector, and the purpose of, for example, 90° bent transfer can be achieved. However, this electrical connector 100 adopts a two-piece structure, and the structure is relatively complex, which in turn leads to the problem that the electrical connector 100 has a relatively large volume; moreover, the mating connector and the cable connector are usually cylindrical, and the forming method is machining, which will cause material waste, low production efficiency, and high cost during processing. How to solve these problems has become a difficult problem that those skilled in the art urgently need to solve. To solve these problems, this application provides a transfer terminal (as Figures 1 to 7 shown), an electrical connector having the transfer terminal (as Figure 8 , Figure 9 and Figure 10 shown) and a vehicle having the electrical connector (as Figure 11 shown).

[0043] Please refer to Figure 1 and Figure 8The adapter terminal 10 of the electrical connector 100 of the embodiment of the present application includes a connecting portion 11, a transition portion 12 and a plug-in portion 13. The transition portion 12 is bent to form a plug-in space and includes two opposite ends spaced apart from each other. The connecting portion 11 is connected to the opposite ends of the transition portion 12. The plug-in portion 13 is arranged on the transition portion 12 and includes at least one pair of spring leaves 131. In each pair of spring leaves 131, two spring leaves 131 are arranged facing each other. Each spring leaf 131 at least partially protrudes into the plug-in space to form a contact located in the plug-in space. The contact is used to contact the pin 2 inserted between each pair of spring leaves 131. The insertion direction of the pin 2 intersects with the extension direction of the connecting portion 11 to form an angle.

[0044] The electrical connector 100 is generally referred to as a power connector or an electrical connector. It is a device for forming a detachable electrical connection. Its main function is to provide a reliable conduction path between two or more electrical components so that current can flow between the devices. The electrical connector is usually composed of two matching parts, one of which is installed at one end of the circuit, and the other part can be inserted or connected to this part to form a complete circuit. The adapter terminal 10 is a device for connecting and disconnecting wires or cables in a circuit, and can usually be set in various forms such as screw type, jack type, pin type, spring clip type, etc. The application of the adapter terminal 10 can facilitate the installation, removal and replacement of wires, while ensuring the stability and safety of the circuit. Therefore, it is widely used in various electronic equipment, power systems, automation equipment and other fields. The adapter terminal 10 in the present application adopts an integrated bending molding structure, and the structure is relatively simple, so that the volume of the electrical connector 100 is small, the connecting part 11 is usually square, and the plug-in part 13 is mainly composed of a square spring 131. There is less material waste during the processing process, high production efficiency and low cost.

[0045] Specifically, the adapter terminal 10 in the present application includes a connecting portion 11, a transition portion 12 and a plug-in portion 13, wherein the transition portion 12 is a transition portion for connecting the connecting portion 11 and the plug-in portion 13, and the transition portion 12 is bent to form a plug-in space, and includes two opposite ends spaced from each other, thereby providing sufficient accommodation space for the plug pin 2. The connecting portion 11 is a portion for connecting the adapter terminal 10 with other circuits or cables, and is connected to both opposite ends of the transition portion 12, thereby ensuring that when the adapter terminal 10 is configured for use, the current can be conducted to the transition portion 12 through the connecting portion 11. The plug-in portion 13 is arranged on the transition portion 12, thereby ensuring that the current can be conducted between the plug-in portion 13 and the transition portion 12. The plug-in portion 13 is a portion of the adapter terminal 10 for plugging in other circuit elements, and in the present application is mainly used for plugging in the plug pin 2, thereby enabling the current to be conducted between the plug-in portion 13 and the plug pin 2, so as to help the electrical connector 100 achieve circuit switching.

[0046] Furthermore, the plug-in portion 13 includes at least one pair of reeds 131, wherein the reeds 131 are a part made of elastic metal material, and are mainly used to provide reliable electrical contact when the two parts of the electrical connector 100 are connected. The main purpose of the design of the reeds 131 is to maintain stable contact with another conductor through its own elastic deformation, thereby ensuring the continuous flow of current. The shape and design of the reeds 131 can be diversified as needed, and common ones include needle-shaped, hole-shaped, leaf-shaped, etc., which can be single-piece or multi-piece. They are usually made of copper alloys or highly conductive and corrosion-resistant metals such as gold and silver to ensure good conductivity and durability. In the present application, in each pair of spring leaves 131, two spring leaves 131 are arranged facing each other, and each spring leaf 131 at least partially protrudes into the plug-in space to form a contact located in the plug-in space, and the contact is used to interfere with the pin 2 inserted between each pair of spring leaves 131. This structure can ensure that the pin 2 can be clamped by the spring leaves 131 arranged in pairs, while also ensuring that the insertion direction of the pin 2 intersects with the extension direction of the connecting portion 11 at an angle. In actual application, the electrical connector 100 usually needs to perform circuit switching according to different angle requirements. Since in the present application, the insertion direction of the pin 2 intersects with the extension direction of the connecting portion 11 to form an angle, it can meet the different usage requirements of the electrical connector 100.

[0047] In certain embodiments, see Figure 8 , the insertion direction of the pin 2 is perpendicular to the extension direction of the connecting portion 11 .

[0048] It is understandable that in the circuit of new energy electric vehicles, the electrical connector 100 usually requires a 90° switch, that is, in order to meet the needs of actual applications, in the present application, the insertion direction of the pin 2 is set to be perpendicular to the extension direction of the connecting portion 11. When the electrical connector 100 is configured for use, the current flows through the connecting portion 11, the transition portion 12, the plug-in portion 13 and the pin 2 in sequence, thereby achieving the purpose of performing a 90° switch in the circuit through the electrical connector 100.

[0049] In certain embodiments, see Figure 2 The spring sheet 131 is stamped and formed on the transition portion 12, and the opposite ends of the transition portion 12 are respectively connected to the first sub-connection portion 111 and the second sub-connection portion 112. The transition portion 12 formed with the spring sheet 131 is bent, and the first sub-connection portion 111 and the second sub-connection portion 112 are connected to form the connection portion 11, so as to form an integrated structure of the transfer terminal 10.

[0050] Specifically, the reed 131 is fixed to the transition portion 12 by stamping, which enables the reed 131 to have good tensile strength and hardness, so as to ensure that when the adapter terminal 10 is configured for use, the reed 131 is not easily broken, which improves the durability of the adapter terminal 10. The opposite ends of the transition portion 12 are respectively connected to a first sub-connection portion 111 and a second sub-connection portion 112, thereby ensuring current conduction between the first sub-connection portion 111 and the second sub-connection portion 112 and the transition portion 12, and ensuring the effectiveness of the electrical connector 100. The transition portion 12 formed with the reed 131 is bent, so as to ensure that the connection portion 11 formed by connecting the transition portion 12 with the first sub-connection portion 111 and the second sub-connection portion 112 is smoothly connected as a whole, thereby forming the adapter terminal 10 with an integral structure. This integral structure is relatively simple. Compared with the current technology, the adapter terminal 10 with the integral structure of the present application can reduce the volume of the electrical connector 100, reduce material waste during the processing process, improve the production efficiency of the electrical connector 100, and reduce the production cost of the electrical connector 100.

[0051] In some embodiments, please refer to Figure 4 , the connection portion 11 includes a first sub-connection portion 111 and a second sub-connection portion 112, and the first sub-connection portion 111 and the second sub-connection portion 112 are respectively fixedly connected together after extending from the opposite ends of the transition portion 12.

[0052] Specifically, the structure of the transition portion 12 has opposite ends, and each end needs to be connected to the connection portion 11. Therefore, the first sub-connection portion 111 and the second sub-connection portion 112 are respectively fixedly connected together after extending from the opposite ends of the transition portion 12, so as to form the connection portion 11 through the first sub-connection portion 111 and the second sub-connection portion 112. By this integral molding method, the connection portion 11 is connected to the transition portion 12, ensuring that the structure of the adapter terminal 10 is an integral structure, thereby reducing the volume of the electrical connector 100, reducing material waste during the processing process, improving the production efficiency of the electrical connector 100, and reducing the production cost of the electrical connector 100.

[0053] In some embodiments, the connection mode between the connection portion 11 and the cable is ultrasonic welding.

[0054] It can be understood that ultrasonic welding is a process that uses high-frequency vibration waves to be transmitted to the surface of the welded workpiece, generates heat through friction to melt the parts and bond them together. This welding method can complete the welding in a short time, improve the production efficiency, and at the same time improve the structural strength of the joint part and increase the service life of the electrical connector 100.

[0055] In some embodiments, please refer to Figure 5One of the first sub-connection part 111 and the second sub-connection part 112 is provided with a protrusion, and the other of the first sub-connection part 111 and the second sub-connection part 112 is provided with a mounting hole, and the protrusion is accommodated in the mounting hole and riveted to the mounting hole.

[0056] It can be understood that the first sub-connection part 111 and the second sub-connection part 112 are connected by one of them being provided with a protrusion and the other being provided with a mounting hole corresponding to the protrusion. When the adapter terminal 10 is configured for use, each protrusion is placed in the mounting hole corresponding to it and fixed to the mounting hole by riveting, thereby forming a strong and durable connection that can withstand large tensile and shear forces and has good structural strength. Compared with the welding connection method, the riveting method used in this application exhibits better fatigue resistance under cyclic loads and is suitable for use in environments requiring long-term vibration or repeated loads, thereby ensuring that the adapter terminal 10 has better structural strength and fatigue resistance, thereby improving the service life of the electrical connector 100 and reducing circuit maintenance pressure.

[0057] In certain embodiments, see Figure 5 The top of the protrusion is provided with a guide fillet 113.

[0058] It is understandable that when the first sub-connection part 111 and the second sub-connection part 112 are riveted together, that is, the protrusion of one is riveted to the mounting hole of the other, in order to avoid collision between the protrusion and the mounting hole, which may cause damage to the first sub-connection part 111 and / or the second sub-connection part 112, a guide fillet 113 is provided at the top of the protrusion. The guide fillet 113 refers to the rounded transition part added when designing the edge or corner of an object. In the present application, the guide fillet 113 is provided at the top of the protrusion, which plays a guiding role in the processing process, can avoid processing difficulties caused by sharp corners and wear of the adapter terminal 10, and at the same time, when the adapter terminal 10 is configured for use, the guide fillet 113 can increase the structural strength of the adapter terminal 10, reduce stress concentration, and improve the fatigue resistance of the material.

[0059] In certain embodiments, see Figure 4 The transition portion 12 includes a first sub-portion 121, a second sub-portion 122 and a third sub-portion 123. The first sub-portion 121 and the second sub-portion 122 are arranged opposite to each other. The third sub-portion 123 is bent and connects the first sub-portion 121 and the second sub-portion 122. The opposite ends of the transition portion 12 are respectively one end of the first sub-portion 121 away from the third sub-portion 123 and one end of the second sub-portion 122 away from the third sub-portion 123. The first sub-portion 121, the second sub-portion 122 and the third sub-portion 123 surround a plug-in space open on three sides. The two reeds 131 in each pair of reeds 131 are respectively arranged on the first sub-portion 121 and the second sub-portion 122.

[0060] Specifically, the transition portion 12 is composed of three parts: a first sub-portion 121, a second sub-portion 122, and a third sub-portion 123. The first sub-portion 121 and the second sub-portion 122 are oppositely arranged, and there is a gap between the first sub-portion 121 and the second sub-portion 122, thereby reserving a receiving space for receiving the pin 2. The third sub-portion 123 is bent and connected to the first sub-portion 121 and the second sub-portion 122, thereby ensuring the structural stability of the receiving space between the first sub-portion 121 and the second sub-portion 122, and ensuring that when the electrical connector 100 is configured for use, the pin 2 will not be damaged by extrusion due to insufficient structural stability of the transition portion 12. The opposite ends of the transition portion 12 are respectively one end of the first sub-portion 121 away from the third sub-portion 123 and one end of the second sub-portion 122 away from the third sub-portion 123, that is, the third sub-portion 123 is connected to one end of the first sub-portion 121 and the second sub-portion 122, and the ends of the first sub-portion 121 and the second sub-portion 122 away from the third sub-portion 123 are used to connect to the connecting portion 11. The first sub-portion 121, the second sub-portion 122, and the third sub-portion 123 enclose a plugging space that is open on three sides, that is, when the electrical connector 100 is configured for use, it is a space for receiving the pin 2. Two reed pieces 131 in each pair of reed pieces 131 are respectively arranged on the first sub-portion 121 and the second sub-portion 122, that is, the two reed pieces 131 are arranged in pairs opposite to each other, and can be used to clamp the pin 2 to ensure that the electrical connector 100 can smoothly achieve circuit transfer.

[0061] In some embodiments, please refer to Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 , the plugging portion 13 includes at least one pair of first reed pieces 1311 and at least one pair of second reed pieces 1312; in each pair of first reed pieces 1311, two first reed pieces 1311 are respectively arranged on the first sub-portion 121 and the second sub-portion 122, and each first reed piece 1311 at least partially protrudes into the plugging space to form a first contact 13111 located in the plugging space; in each pair of second reed pieces 1312, two second reed pieces 1312 are respectively arranged on the first sub-portion 121 and the second sub-portion 122, and each second reed piece 1312 at least partially protrudes into the plugging space to form a second contact 13121 located in the plugging space; in the insertion direction of the pin 2, the first contact 13111 and the second contact 13121 are arranged in a front-back dislocation manner.

[0062] Specifically, the insertion part 13 includes at least a pair of first elastic pieces 1311 and at least a pair of second elastic pieces 1312. By arranging multiple pairs of elastic pieces 131 in the insertion part 13, the clamping of the pin 2 can be further ensured, preventing the pin 2 from falling off due to too few elastic pieces 131. In each pair of first elastic pieces 1311, the two first elastic pieces 1311 are respectively arranged on the first sub-part 121 and the second sub-part 122, that is, the two first elastic pieces 1311 are arranged oppositely to ensure that the paired first elastic pieces 1311 play a role in clamping an object. Each first elastic piece 1311 at least partially protrudes into the insertion space to form a first contact point 13111 located in the insertion space, that is, the contact point for clamping the object. In each pair of second elastic pieces 1312, the two second elastic pieces 1312 are respectively arranged on the first sub-part 121 and the second sub-part 122, that is, the two second elastic pieces 1312 are arranged oppositely to ensure that the paired second elastic pieces 1312 play a role in clamping an object. Each second elastic piece 1312 at least partially protrudes into the insertion space to form a second contact point 13121 located in the insertion space, that is, the contact point for clamping the object. In the insertion direction of the pin 2, the first contact point 13111 and the second contact point 13121 are arranged in a staggered manner front and back, so as to effectively reduce the insertion force when the pin 2 is inserted into the insertion space with three sides open surrounded by the first sub-part 121, the second sub-part 122 and the third sub-part 123, reduce the wear of the connection terminal 10 and the pin 2, and at the same time reduce the swing of the pin 2 in the insertion space. When the electrical connector 100 is configured for use, since the pin 2 is firmly fixed in the insertion space, the conductive ability of the adapter terminal 10 will be further improved and the current loss will also be further reduced.

[0063] In some embodiments, please refer to Figure 9 , in the insertion direction of the pin 2, both the first sub-part 121 and the second sub-part 122 sequentially have a relative first end (lower) and a second end (upper);

[0064] In each pair of first elastic pieces 1311, the opposite ends of one of the first elastic pieces 1311 are respectively connected to the opposite ends of the first sub-part 121, and the opposite ends of the other first elastic piece 1311 are respectively connected to the opposite ends of the second sub-part 122. Each first elastic piece 1311 includes a first bending 13112 and a second bending 13113.

[0065] In each pair of second reeds 1312, the opposite ends of one second reed 1312 are respectively connected to the opposite ends of the first sub-portion 121, and the opposite ends of the other second reed 1312 are respectively connected to the opposite ends of the second sub-portion 122.

[0066] Specifically, in the insertion direction of the pin 2, the first sub-section 121 and the second sub-section 122 each have a first end (bottom) and a second end (top) respectively. By arranging the first sub-section 121 and the second sub-section 122 relative to each other, it is ensured that the spring sheets 131 located on the first sub-section 121 and the second sub-section 122 can clamp the pin 2. In each pair of first reeds 1311, the opposite ends of one of the first reeds 1311 are respectively connected to the opposite ends of the first sub-portion 121, so as to ensure that the first reed 1311 can be fixed on the first sub-portion 121, and the opposite ends of the other first reed 1311 are respectively connected to the opposite ends of the second sub-portion 122, so as to ensure that the other first reed 1311 can be fixed on the second sub-portion 122, thereby ensuring that the oppositely arranged pairs of first reeds 1311 can be stably fixed on the transition portion 12, each first reed 1311 includes a first bend 13112 and a second bend 13113, and the first bend 13112 and the second bend 13113 can be arranged at any place of the first reed 1311, and the first bend 13112 and the second bend 13113 can be arranged at any place of the first reed 1311. One end of a bend 13112 is connected to the first end, one end of a second bend 13113 is connected to the second end, the other end of the first bend 13112 and the other end of the second bend 13113 are connected in the plug-in space, and a first contact 13111 is formed at the connection, that is, a first contact 13111 for clamping an object is formed in the plug-in space through the corresponding first bend 13112 and the second bend 13113, and at the same time, the first bend 13112 and the second bend 13113 can also enhance the elasticity of the first spring leaf 1311, enhance the tightness of the first spring leaf 1311 to fix the object, avoid shaking of the fixed object, and reduce the mechanical wear of the first spring leaf 1311, thereby increasing the service life of the adapter terminal 10.

[0067] Specifically, in each pair of second reeds 1312, the opposite ends of one of the second reeds 1312 are respectively connected to the opposite ends of the first sub - part 121, so as to ensure that the second reed 1312 can be fixed on the first sub - part 121. The opposite ends of the other second reed 1312 are respectively connected to the opposite ends of the second sub - part 122, so as to ensure that the second reed 1312 can be fixed on the second sub - part 122. Furthermore, it is ensured that the paired second reeds 1312 arranged oppositely can be stably fixed on the transition part 12.

At the same time, the third bend 13122 and the fourth bend 13123 can also enhance the elasticity of the second reed 1312, enhance the fastening degree of the second reed 1312 for fixing the object, prevent the fixed object from shaking, and at the same time reduce the mechanical wear of the second reed 1312, and improve the service life of the adapter terminal 10.

[0068] In some embodiments, refer to Figure 9 , the transition part 12 further includes a guiding sub - part 124. One end of the guiding sub - part 124 is connected to the first sub - part 121 and / or the second sub - part 122, and the other end of the guiding sub - part 124 is bent towards the inside of the insertion space. The guiding sub - part 124 is used to guide the pin 2 when it is inserted into the insertion space.

[0069] It can be understood that one end of the guiding sub - part 124 is connected to the first sub - part 121 and / or the second sub - part 122, so as to ensure the current conduction between the guiding sub - part 124 and the first sub - part 121 and / or the second sub - part 122. The other end of the guiding sub - part 124 is bent towards the inside of the insertion space to guide the pin 2 when it is inserted into the insertion space, thereby reducing the insertion force when the pin 2 is inserted into the insertion space, avoiding the collision and damage of the reed 131 and the pin 2 in the insertion space due to excessive insertion force, and improving the service life of the electrical connector 100.

[0070] In some embodiments, refer to Figure 9 , the other end of the guiding sub - part 124 is bent towards the inside of the insertion space to form a bending angle α, and the bending angle α is less than or equal to 75° and greater than or equal to 30°.

[0071] Specifically, the other end of the guiding sub - part 124 bends towards the inside of the insertion space to form a bending angle α, which serves to guide the insertion of the pin 2 into the insertion space. At the same time, the present application limits the angle range of the bending angle α. When the bending angle α is too small, that is, when the bending angle α is less than 30°, the bending degree of the guiding sub - part 124 is too large, resulting in unstable stress on the structure forming the insertion space. When the electrical connector 100 is configured for use, it is likely to deform due to unstable structure, causing damage to the pin 2. When the bending angle α is too large, that is, when the bending angle α is greater than 75°, the bending degree of the guiding sub - part 124 is too small, and it cannot reduce the insertion force when the pin 2 is inserted into the insertion space. It is easy to cause the spring piece 131 and the pin 2 in the insertion space to be damaged due to excessive insertion force, reducing the service life of the electrical connector 100.

[0072] In some embodiments, referring to Figure 9 , a guiding C - angle 1242 is provided on the side of the guiding sub - part 124 facing the pin 2.

[0073] Specifically, the guiding C - angle 1242 is arranged on the side of the guiding sub - part 124 facing the pin 2, which is used to reduce the insertion force when the pin 2 is inserted into the insertion space, avoid the spring piece 131 and the pin 2 in the insertion space from being damaged due to excessive insertion force, and improve the service life of the electrical connector 100.

[0074] In some embodiments, referring to Figure 3 , an installation groove 125 is provided on the transition part 12. The installation groove 125 is used to cooperate with the positioning rod, and the included angle β between the two inner side surfaces of the installation groove 125 close to the connection part 11 is an acute angle.

[0075] Specifically, the transition part 12 realizes the cooperation with the positioning rod on the housing through the self - provided installation groove 125. For example, the transition part 12 usually realizes the cooperation with the positioning rod on the plastic housing through the installation groove 125, so as to realize the limitation of the adapter terminal 10. The included angle β between the two inner side surfaces of the installation groove 125 close to the connection part 11 can be 87°. Through this included angle β, the transition part 12 can increase the pulling - off force between the installation groove 125 and the positioning rod on the housing, thereby increasing the holding force of the adapter terminal 10 in the plastic housing.

[0076] In summary, the adapter terminal 10 in the embodiment of the present application includes a connecting portion 11, a transition portion 12 and a plug-in portion 13. The transition portion 12 is bent to form a plug-in space and includes two opposite ends spaced from each other, so that the pin 2 is accommodated through the plug-in space.

The plug-in portion 13 is arranged in the transition portion 12 and includes at least one pair of spring leaves 131. In each pair of spring leaves 131, two spring leaves 131 are arranged facing each other, and each spring leaf 131 at least partially protrudes into the plug-in space to form a contact located in the plug-in space. The contact is used to contact the pin 2 inserted between each pair of spring leaves 131, and the insertion direction of the pin 2 intersects with the extension direction of the connecting portion 11 to form an angle. The adapter terminal 10 of the present application adopts an integrated bending molding structure, which is relatively simple in structure, so that the volume of the electrical connector 100 is small. The connecting part 11 is usually square, and the plug-in part 13 is mainly composed of square spring leaves. There is less material waste in the processing process, high production efficiency and low cost.

The plug-in portion 13 is disposed on the transition portion 12 and includes at least one pair of spring leaves 131. In each pair of spring leaves 131, two spring leaves 131 are disposed opposite to each other. Each spring leaf 131 at least partially protrudes into the plug-in space to form a contact point located in the plug-in space. The contact point is used to contact with a pin 2 inserted between each pair of spring leaves 131. The insertion direction of the pin 2 intersects with the extension direction of the connecting portion 11 to form an angle.

[0078] In some embodiments, the electrical connector 100 further includes a pin 2, which is inserted into the plug-in space from between each pair of spring leaves.
