The present application can be practiced in other different embodiments and with various modifications and in various sub-combinations. The specific embodiments described herein are presented only as illustrative examples of the present application, and are not intended to limit the scope of the present application. The drawings are not to scale and are intended for purposes of illustration only and not limitation. The following detailed description of the application is presented in the order of actions taken by the application, and is not intended to limit the application described herein. ​​

[0041] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the associated listed items.

[0042] The electrical connector assembly with a shunt structure of the present invention includes a main connector and a shunt connector. The main connector has an input interface, an output interface, and a shunt interface. The main connector is electrically connected to a power supply element via the input interface located on a first side to receive current or signal input, and outputs a portion of the received current or signal via the output interface located on a second side; the shunt interface located on a third side outputs a portion of the received current. It is noteworthy that the first, second, and third sides can be a complete surface or part of a complete surface of the main connector. That is, the first, second, and third sides can be located on different surfaces of the main connector or on the same surface. The main connector contains multiple electrical terminals, one end located at the input interface and the other end at the output interface, for current and / or signals to be input through the input interface and transmitted to the output interface for output; or multiple power terminals for current transmission. With this design, the current supplied by the power supply element, i.e., electrical power, can be easily shunted by the electrical connector assembly of the present invention to reduce power loss. The power supply element corresponding to the electrical connector assembly of the present invention can be a paired electrical connector or a power supply, or other element capable of providing current, thus its application range is extremely wide. The present invention will be described below through various embodiments, and the component names in each embodiment may vary depending on the application scenario, but this does not affect the current shunting function of the electrical connector assembly.

[0043] [First Embodiment]

[0044] See Figures 1 to 3 As shown, a first embodiment of the present invention provides an electrical connector assembly with a shunt structure, comprising a first connector 1a and a pair of second connectors 3a and 3a'. The first connector 1a has a first insulating housing 10, a plurality of first electrical terminals 20, and a pair of adapter sockets 10T and 10T'. The first insulating housing 10 includes a first side surface and a second side surface. The first side surface is rectangular, and its length direction is parallel to a second direction D2 (see figure). Figure 2The first side has a plug-in side 103 for providing a plug-in input interface for electrical connection to a mating element (e.g., a power supply element), while the second side has an output interface for outputting the current and / or signal provided by the mating element. The first connector 1a can be referred to as an electrical connector with a shunt structure. Additionally, the first insulating housing 10 and at least one first electrical terminal 20 can be referred to as a shunt device, which is used to mate with an adapter socket to shunt the current of the electrical connector.

[0045] In this embodiment, the first insulating housing 10 further has a top surface 101 and a bottom surface 102 opposite to the top surface 101. The first connector 1a is connected to a circuit board P, with an input interface in a slot 11 and an output interface located on the bottom surface 102. The slot 11 connects the insertion side 103 and the bottom surface 102. The slot 11 allows a mating element (not shown) to be inserted along a first direction D1 (see figure). Figure 2 Insertion is performed where the first direction D1 is perpendicular to the second direction D2. The mating element can be a mating connector or the output terminal of a power supply, such as the edge interface of the output terminal of a CRPS power supply. In this case, the slot 11 is an edge interface or a plug-in input interface of a power board. The slot 11 can serve as a power input interface and / or a signal input interface, or when there are multiple slots 11, each can serve as a power input interface or a signal input interface. Each of the plurality of first electrical terminals 20 has a first contact portion 21 extending into the slot 11 (i.e., the plug-in input interface) and a first pin 22 extending into the bottom surface 102 of the first insulating housing 10 (i.e., the output interface), and the first contact portion 21 and the first pin 22 are electrically connected to each other. In this embodiment, the bottom surface 102 of the first insulating housing 10 serves as a power output interface and / or a signal output interface.

[0046] In this embodiment, the first contact portion 21 of the first electrical terminal 20 is located at the input interface. Multiple first contacts 21 can define at least one planar contact surface for electrical connection when a mating element is inserted. For example, the first contacts 21 collectively form a planar contact surface parallel to the circuit board P (i.e., the planar contact surface is parallel to the first direction D1 and the second direction D2); or the first contacts 21 respectively form multiple planar contact surfaces perpendicular to the circuit board P (i.e., the planar contact surfaces are perpendicular to the second direction D2), for respectively electrically connecting to a power supply potential or a ground potential of the mating element. The first electrical terminal can define the input interface by pairs of electrical terminals; please refer to [link to relevant documentation]. Figure 1The first electrical terminals 20 and 20S are arranged in pairs, each of the first electrical terminals 20 and 20S has a first side contact portion and a second side contact portion, so as to form a planar contact area together and define a slot therebetween. The slot is adapted to receive a mating element, such as a terminal of a plug connector, a power board, a bus bar, etc. That is, the mating element has a plate shape or a plurality of terminals arranged in a same plane, and each of the terminals has at least one planar contact surface adapted to mate with the input plane of the electrical connector assembly. The slot can be a single slot or a plurality of slots parallel to the second direction D2 or a plurality of slots perpendicular to the second direction D2. However, the present application is not limited thereto, and there can be only one side of the first electrical terminals. In some high power applications, the thickness of the first electrical terminals 20 (i.e. the thickness in the direction perpendicular to the slot) is greater than or equal to 0.3 mm, and preferably greater than or equal to 0.6 mm. In order to avoid excessive insertion force, the thickness of the first electrical terminals 20 is less than or equal to 2 mm, and preferably less than or equal to 1 mm. In this way, a better balance between the current carrying capacity and the normal force with the mating element can be achieved. In addition, the first contact portion 21 of each of the first electrical terminals 20 (and 20S) can include a plurality of spring arms. In addition to avoiding excessive insertion force, the spring arms can also avoid the distortion of the planar contact surface caused by the assembly tolerance in the single slot application environment, so as to avoid the problem of excessive insertion force difference between the two ends of the contact surface.

[0047] The first pin 22 of the first electrical terminal 20 extends out of the second side surface, so as to form an output interface for connecting with the circuit board P. The connection manner can be soldering or crimping. Therefore, the first pin 22 can be a soldering pin or a crimping pin with a fish eye. When the first pin 22 is a soldering pin, the first pin 22 can be connected with the circuit board P by a through-hole soldering technology and / or a surface mount technology. The first connector 1a can be connected with the circuit board P in a vertical manner or a right-angle manner. That is, the first pin 22 can have a 90-degree bending portion or be a straight line type. When the first pin 22 is a straight line type (not shown), the second side surface is located at an opposite side of the first side surface. At this time, the first direction D1 is perpendicular to the surface of the circuit board P, and the mating element is inserted along the first direction D1. When the first pin 22 has a 90-degree bending portion (as shown in FIG. 1), the second side surface is located at the same side of the first side surface. At this time, the first direction D1 is parallel to the surface of the circuit board P, and the mating element is inserted along the first direction D1. Figure 1 and Figure 2), the second side is located on the bottom surface 102, the curved portion can be within the first insulating housing 10 to achieve the protection and support or fix the first pins 22. At this time, the first direction D1 is parallel to the surface of the circuit board P, the counterpart element is inserted along the first direction D1. In the embodiment, the first connector 1a is connected to the circuit board P in the way of sinking. That is, the bottom surface 102 contains a first bottom surface area and a second bottom surface area (the second side), the first pins 22 are extended outwardly from the second bottom surface area. The distance between the second bottom surface area and the top surface 101 is preferably less than the distance between the first bottom surface area and the top surface 101, so as to reduce the overall height when the first connector is connected to the circuit board P. While the top surface 101 can be a flat surface, or as Figure 1 usual, is also divided into a first top surface area and a second top surface area on different height surfaces, the first top surface area is located on the opposite side of the first bottom surface area, and the second top surface area is located on the opposite side of the second bottom surface area.

[0048] The adapter socket 10T is a shunt socket, which is located on a third side of the first insulating housing 10, used to provide a fixed effect when the second connector 3a (or can be called a shunt connector) is connected with the first connector 1a, and to make the second electrical terminals of the second connector 3a electrically connected with at least part of the first electrical terminals 20 of the first connector 1a. The third side is preferably located on a different side from the first side of the input interface of the first connector 1a and the second side of the output interface. For example, the first side is located on the front side, the second side is located on the bottom surface, and the third side can be located on the top surface or the back side opposite to the front side. In Figure 1 the embodiment, the adapter socket 10T is located on the top surface 101.

[0049] In the embodiment, the top surface of the first insulating housing 10 has two identical adapter sockets, which can be referred to as a first adapter socket (10T) and a second adapter socket (10T'). The first adapter socket 10T is configured to receive the second connector 3a, and the second adapter socket 10T' is configured to receive a third connector 3a' to electrically connect at least one of the plurality of electrical terminals to each other. The adapter socket 10T has a pair of limiting side walls 12. The adapter socket 10T is a rectangle, and the pair of limiting side walls 12 are preferably short side walls. The top surface 10 has a through hole on the top surface 10, and a bare area 14 is formed between the pair of limiting side walls 12. That is, the adapter socket 10T corresponds to the through hole of the top surface 10, so that a through slot defined by the pair of limiting side walls 12 is in communication with the plug-in input interface and the output interface through the through hole. At least one of the first electrical terminals 20 is exposed to the bare area 14. Specifically, the first electrical terminal 20 has a middle portion 23, and the middle portion 23 of the first electrical terminal 20 corresponding to the bare area 14 is exposed as a through contact surface or an external contact portion to electrically connect with the second connector 3a when the second connector 3a is inserted. The middle portion 23 is exposed to the bare area 14, and the middle portion 23 is located between the first contact portion 21 and the first pin 22. The middle portion 23 of the embodiment is a planar shape, and the middle portion 23 has a first contact surface parallel to the second direction D2. In other words, the first electrical terminal 20, 20S extends from the middle portion 23 to a first side contact portion and an opposite second side contact portion of opposite two inner side edges of the at least one input interface (slot 11) to form a planar contact area. The first pin 22 extends from the middle portion 23 to the bottom surface 102 of the first insulating housing 10 and extends out of the second bottom surface to form an output interface, which can be connected to the circuit board P or the mating connector.

[0050] Please refer to Figures 4 to 7 The second connector 3a of the embodiment is a through device and is pluggably arranged in the adapter socket 10T. The second connector 3a has a second insulating housing 30 and at least one second electrical terminal 40 fixed to the second insulating housing 30. The second electrical terminal 40 has a second contact portion 42 and a second pin 43 extending from the second contact portion 42. The second contact portion 42 is exposed to the bottom of the second insulating housing 30 (also referred to as a through input interface 301, please refer to Figure 4 ), and has a contact surface parallel to the through contact surface of the first electrical terminal 20. That is, the contact surface of the second contact portion 42 is parallel to the bottom of the second insulating housing 30. The second pin 43 (also referred to as a through output interface 302, please refer to Figure 4) in the second insulating housing 30 and extending toward or out of the rear end surface of the second insulating housing 30 to connect the at least one cable C. The rear end surface is adjacent to and perpendicular to the bottom surface. Therefore, when the second connector 3a is disposed in the adapter socket 10T, the contact surface of the second contact portion 42 abuts against the shunt contact surface of the first connector la to electrically connect the second electrical terminal 40 with the first electrical terminal 20. Therefore, the current of the first electrical terminal 20 is shunted to the second electrical terminal 40 and provided to a line end connector (not shown) via the at least one cable C. The second contact portion 42 of the second electrical terminal 40 is preferably exposed to the bottom of the second connector 3 and can extend into the first insulating housing 30 through the shunt hole (and the exposed area 14) to electrically connect with the first electrical terminal 20; the second pin 43 is connected with the at least one cable C, preferably extending out of the second insulating housing 30 to connect with the at least one cable C. In order to save the overall height of the first connector la and the second connector 3a when they are connected with each other, the second pin 43 can provide a cable connecting surface parallel to the circuit board P (i.e. parallel to both the first direction Dl and the second direction D2) to connect with the at least one cable C. In some applications, the width of the connector in the front-rear direction (i.e. in the first direction Dl) is limited, and in order to save the overall width of the first connector la and the second connector 3a when they are connected with each other, the second pin 43 can provide a cable connecting surface perpendicular to the circuit board P (i.e. perpendicular to the first direction Dl) to connect with the at least one cable C. That is, the cable connecting surface of the second pin 43 can be designed in a manner parallel to the second contact portion 42 (or the shunt contact surface of the first electrical terminal 20) or perpendicular to the second contact portion 42 (or the shunt contact surface of the first electrical terminal 20). Please refer to Figures 4-7 , the second electrical terminal 40 extends out of the second insulating housing 30, and the second pin 43 is L-shaped to connect with the at least one cable C. The at least one cable C can be fixed on the cable connecting surface of the second pin 43 by soldering or ultrasonic welding. The at least one cable C has a plurality of conductive fibers, which can be fixed in shape and adhered to each other in advance by soldering or ultrasonic welding to facilitate the subsequent fixation on the cable connecting surface of the second pin 43; or the plurality of conductive fibers are received by a jig and fixed on the cable connecting surface by soldering or ultrasonic welding while being adhered to each other. When the second pin 43 is connected with the at least one cable C outside the second insulating housing 30, in order to avoid electric shock caused by the user touching the part of the second electrical terminal 40 exposed outside the second insulating housing and the part of the at least one cable C exposed outside the insulating layer, an insulating sleeve or layer can be additionally fixed outside the part where the second pin 43 is connected with the at least one cable C.

[0051] In some applications, the power terminals 40 can be electrical terminals that can carry current or signals. Thus, the second connector 3a has the function of shunting current and carrying signals.

[0052] Referring to Figure 8 , the second connector 3a of the present embodiment is inserted into the adapter socket 10T in a direction perpendicular to the top surface 101 of the first connector 1a. When the second connector 3a is inserted into the adapter socket 10T, the second contact portions 42 of the second electrical terminals 40 contact the intermediate portions 23 of the first electrical terminals 20. At the same time, the second insulating housing 30 is confined between the pair of confining side walls 12. In this way, the present embodiment enables current from the first connector 1a to pass through the intermediate portions 23 of the first electrical terminals 20 to the second electrical terminals 40 of the second connector 3a, and to be transmitted to other components requiring current via the cable C.

[0053] Referring to Figure 1 , the exposed area 14 is located in the adapter socket 10T and forms at least one exposed hole 140. The exposed hole 140 is formed by the exposed area 14 being recessed downward from the bottom of the adapter socket 10T and is in communication with the slot 11. The exposed hole 140 exposes the intermediate portions 23 of the first electrical terminals 20. The first electrical terminals 20 exposed in the exposed area 140 include a power terminal (e.g., the first electrical terminal 20 of the left first shunt slot of Figure 1 ) that provides a power potential and a power terminal (e.g., the first electrical terminal 20 of the right second shunt slot of Figure 1 ) that provides a ground potential.

[0054] In another application, the first shunt slot (or shunt hole) exposes a plurality of first electrical terminals 20, including at least one power terminal that provides a power potential and at least one power terminal that provides a ground potential. The second connector 3a disposed in the first shunt slot also includes a second power terminal corresponding to the power potential and a second power terminal corresponding to the ground potential, and the second power terminals are electrically isolated from each other and are not connected (see Figure 4 ). The cable C also provides the power potential and the ground potential to the electronic components (e.g., connectors) via the second pins corresponding to the second power terminals of the power terminals providing the power potential and the ground potential, respectively. In this way, a single second connector 3a can directly provide a current loop to the electronic components connected to the second connector 3a.

[0055] The cable C connected to the second connector 3a can be in the same direction or in different directions (e.g., opposite directions). Referring to Figure 4, the cables C connected to the same second connector 3a have the same direction. Specifically, the same second connector 3a has two (or more) second electrical terminals 40, and the second pins 43 of the second electrical terminals 40 extend outwardly from one side (hereinafter referred to as the pin side) of the second insulating housing 30 to different positions (i.e., the ends of the second pins 43 are at different distances from the pin side of the second insulating housing 30), so that the cables C connected to the two (or more) second pins 43 have the same direction and are staggered in position. That is, the cable connection surfaces of the two (or more) second electrical terminals 40 are staggered with respect to each other, so that the cables C having the same direction and connected to the cable connection surfaces can be staggered. In Figure 4 In the embodiment shown, the second pins 43 have bending portions that bend the second pins 43 upward. Please also refer to Figure 7 , the bending portions are different in position, so that the corresponding cables C have the same direction but are staggered in position. Thus, if the same second connector 3a has cables C providing power supply potential and ground potential and the cables C have the same direction, the same second connector 3a can be conveniently connected to the same electronic component. Alternatively, in another variant, the bending portions of the second pins 43 can have the same position, but the lengths of the upward extensions thereof are different, so that the cables C connected thereto have the same direction and are staggered in position. Of course, the cables C connected to the same second connector 3a can have two different directions, i.e., left and right, and there is no need to particularly consider whether the positions of the cables C in the direction need to be staggered. Alternatively, please refer to Figure 3 , the top surface of the first insulating housing 10 has two adapter sockets 10T, 10T', and the two connectors 3a, 3a' are respectively inserted into the two adapter sockets 10T, 10T'. The cables C connected to the two connectors 3a, 3a' have different directions, and the two groups of cables C connected to the same connector 3a, 3a' have the same direction, but the two groups of cables C are staggered in position in the same direction.

[0056] Please also refer to Figure 4 and Figure 7 , the bottom surface of the second insulating housing 30 forms a protruding seat 35, and the second insulating housing 30 forms at least one terminal fixing hole 350, and the second electrical terminal 40 passes through the terminal fixing hole 350 and is fixed to the inner wall surface of the terminal fixing hole 350 in interference.

[0057] Please refer to Figure 2 , the adapter socket 10T further has a positioning member 132; please refer to Figure 1 , the second insulating housing 30 forms a positioning portion 312. When the second connector 3a is inserted into the adapter socket 10T, the positioning member 132 and the positioning portion 312 are in mutual abutment, so as to fix (or limit) the position (or movement) of the second connector 3a in at least one direction.

[0058] In this embodiment, the adapter socket 10T further comprises a shunt guide portion, which includes at least one lateral wall 13. The lateral wall 13 is preferably connected to the pair of limiting side walls 12. The adapter socket 10T is rectangular, the lateral wall 13 is a long side wall, and the limiting side walls 12 are short side walls. At least one shunt slot is formed between the four side walls (12, 13), and the shunt slot corresponds to the exposed area 140, so that the intermediate portion 23 is exposed in the at least one shunt slot. The positioning member 132 is recessed from the inner surface of the lateral wall 13, and the positioning portion 312 is protruded from the front end surface of the second insulating housing 30, that is, the other end surface opposite to the rear end surface of the second pin 43. More specifically, the second insulating housing 30 has a body portion 31, and the positioning portion 312 is protruded from the front end surface of the body portion 31. However, the present application is not limited thereto, and please refer to Figure 3 and Figure 4 In another exposed area 14, the positioning member 133 of the adapter socket 10T' can be protruded from the lateral wall 13 facing the exposed area 14, and the positioning portion 314 is recessed from the front end surface of the body portion 31 of the second insulating housing 30 of the third connector 3a'. That is, the positioning member of the adapter socket and the positioning portion of the second insulating housing of the present application can be a recess and a protrusion which are matched with each other, so as to guide the second connector 3a and the third connector 3a' to be respectively inserted into the adapter socket 10T and the adapter socket 10T'. The positioning member of the adapter socket 10T and 10T' can be a foolproof key, which is different from each other in shape, position or number, so as to achieve the effect of preventing mistakes. That is, the first positioning member of the adapter socket 10T can be inserted only by the correct second connector 3a, but other connectors (for example, the third connector 3a') have incompatible positioning portions (or the positioning member and the positioning portion cannot be matched with each other), so as to be unable to be correctly or completely inserted, thereby achieving the effect of preventing mistakes. In this embodiment, the foolproof key is a recess or a protrusion. The adapter socket 10T provides a power supply potential, and the adapter socket 10T' provides a ground potential, so that the second connector 3a is inserted into the adapter socket 10T to provide the power supply potential, and the third connector 3a' is inserted into the adapter socket 10T' to provide the ground potential. Through the design of the foolproof key, the second connector 3a and the third connector 3a' can be prevented from being inserted by mistake to provide an incorrect potential to the electronic element.

[0059] The pair of limiting side walls 12 of the adapter socket 10T each has a guide rail 122, and the two sides of the second insulating housing 30 each forms a guide block 32. The guide block 32 defines at least one vertical guide surface, i.e. perpendicular to the bottom surface of the second insulating housing 30. When the second connector 3a is inserted into the adapter socket 10T, the guide block 32 and the at least one guide surface of the guide rail 122 correspond to each other, so that the guide block 32 slides into the guide rail 122 (as shown in Figure 9 The side surface of the guide block 32 is preferably different from the front end surface and the rear end surface.

[0060] Referring to Figure 1 and Figure 2 , the pair of limiting side walls 12 of the adapter socket 10T each has a locking portion 124, and the two sides of the second insulating housing 30 each has a movable locking arm 34. When the second connector 3a is inserted into the adapter socket 10T, the locking arm 34 engages with the locking portion 124. That is, when the second connector 3a is inserted into a locking position, the locking arm 34 engages with the locking portion 124. The guide rail 122 and the locking portion 124 are located on opposite sides of the limiting side wall 12, i.e. the pair of limiting side walls each has a guide rail 122 and a locking portion 124 located on a first side end and a second side end opposite to the first side end. In addition, the locking portion 124 has a locking plane 125 parallel to the shunt contact surface (in the embodiment shown in Figure 2 , the lower surface of the locking portion 124) to provide a normal force of the second connector 3a perpendicular to the shunt contact surface, so that when the second contact portion 42 of the second electrical terminal 40 and the shunt contact surface of the first electrical terminal abut, there is sufficient normal force to reduce the contact resistance therebetween. The locking arm 34 also has a support plane 344 corresponding to the locking plane 125 (as shown in Figure 4 ) to receive the normal force, and the support plane 344 is parallel to the bottom surface of the second insulating housing 30.

[0061] As shown in Figure 4 , the guide block 32 can simultaneously serve as a locking arm protection device, and is connected in a U-shaped manner to the side surface of the second insulating housing 30 to form a protection through hole 320. A fixed end 340 of the locking arm 34 is fixedly connected to one end of the side surface of the second insulating housing 30, and the locking arm 34 extends through the protection through hole 320 of the guide block 32 to form a free end. The guide block 32 surrounds a portion of the locking arm 34, thereby limiting the displacement amount of the locking arm 34 in the horizontal direction.

[0062] The body portion 31 has a pressing portion 311 (as shown in Figure 4) and the height of the pressing portion 311 is equal to or higher than the height of the locking arm 34. The pressing portion 311 is preferably located on the top surface of the body portion 31, i.e. the top surface of the second insulating housing. When the second connector 3a is inserted into the adapter socket 10T, the user can press the pressing portion 311 to move the second connector 3a to the locking position, and since the height of the pressing portion 311 (i.e. the pressing surface) is not lower than the height of the locking arm 34, the force applied by the user during the locking process does not affect the original locking function of the locking arm 34. As shown in Figure 4 the pressing portion 311 is formed by extending upward from the middle of the body portion 31 and is located between the two locking arms 34. The pressing portion 311 can have two or more force applying members to define a horizontal (i.e. parallel to the bottom surface of the second insulating housing 30) pressing surface, so as to avoid the problem of uneven force application on the left and right sides when the user applies force. Alternatively, the pressing portion 311 can be a single force applying member with a horizontal upper surface as the pressing surface, so as to achieve the effect of even pressing force application.

[0063] The locking arm 34 has a releasing portion 341 and a clamping portion 342. The clamping portion 342 is formed on the free end of the locking arm 34, and the releasing portion 341 extends upward from the clamping portion 342. The releasing portion 341 and the clamping portion 342 are located on the two side edges of the locking arm 34, respectively. Specifically, the releasing portion 341 and the clamping portion 342 are both located on the free end of the locking arm 34, and the releasing portion 341 extends upward from the inner side of the clamping portion 342, so that the two (i.e. the locking arm 34) are L-shaped. The aforementioned supporting surface 344 is located on the free end of the locking arm 34, specifically on the clamping portion 342 and on the outer side of the upper surface of the clamping portion 342. The two releasing portions 341 are located on the two sides of the body portion 31. When the user wants to remove the second connector 3a from the adapter socket 10T, the user presses the releasing portions 341 on the left and right sides inward (i.e. the releasing portions 341 approach each other), so that the locking arm 34 is released from the clamping portion 124 and is pulled upward to completely separate the second connector 3a from the adapter socket 10T. In order to facilitate the user to apply force when moving the second connector 3a upward, the outer side surface of the releasing portion 341 has a force applying portion, so that the outer side surface is uneven to increase the effect of applying force upward. In this embodiment, the force applying portion is a force applying groove 343 located on the releasing portion 341.

[0064] The adapter socket 10T (i.e. the second insulating housing) can have heat dissipation grooves or heat dissipation through holes extending from front to back to increase the heat dissipation capability of the adapter socket 10T itself and the electrical connector assembly as a whole. The heat dissipation grooves or heat dissipation through holes can be designed vertically (to the PCB) or horizontally (to the PCB). When designed vertically, the heat dissipation can be enhanced due to the heat convection upward. When designed horizontally, the horizontal airflow generated by the fan of the system (e.g. a server) in which the adapter socket 10T is located can be blown into or through the horizontal (i.e. parallel to the bottom surface of the second insulating housing, i.e. parallel to the PCB) heat dissipation grooves or heat dissipation through holes to enhance the heat dissipation. Moreover, the heat dissipation grooves or heat dissipation through holes can also increase the surface area of the adapter socket 10T itself and the electrical connector assembly, and at the same time, increase the heat dissipation capability. Please refer to Figure 4 The buckle portion 342 has heat dissipation grooves 346, and the pressing portion 311 has two parallel arm structures to form a heat dissipation groove between the two arm structures. In addition, the protection through hole 320 not only provides the protection function of the locking arm 34, but also increases the heat dissipation capability as a heat dissipation through hole.

[0065] As shown in Figure 8 , the second insulating housing 30 further forms a pair of inner limiting grooves 310, and the locking arms 34 each have an inner limiting portion 345 extending rearwardly from the buckle portion 342 and movably extending into the inner limiting groove 310, and the inner limiting groove 310 limits the vertical displacement of the inner limiting portion 345. The pair of inner limiting grooves 310 are located on the inner side of the guide block 32. In this way, the displacement of the locking arms 34 in the horizontal direction or in the vertical direction can be properly protected from being damaged by external forces.

[0066] The unlocking portion 341 of the locking arm 34 of the present embodiment extends away from the second electrical terminal 40 to provide better safety and avoid the fingers of the operator from accidentally touching the second electrical terminal 40. That is, the second pin 43 of the second electrical terminal 40 and the locking arm 34 are located on opposite sides of the second insulating housing to increase the distance therebetween and reduce the risk of electric shock due to accidental contact with the live part.

[0067] [Second embodiment]

[0068] Please refer to Figures 10 to 15The second embodiment of the present application provides an electrical connector assembly with a shunt structure, which includes a first connector 1b and a second connector 3b. The first connector 1b has a first insulating housing 10 and a plurality of first power terminals 20'. Each of the first power terminals 20' is used to conduct a current with a maximum current greater than or equal to 1A. The second connector 3b has a second insulating housing 30. The difference between the above embodiment and the present embodiment is that the second connector 3b is inserted into the adapter socket 10T in a direction oblique to the top surface of the first connector 1b. The guide rail 122 of the limiting side wall 12 is slightly L-shaped or semi-U-shaped, and the locking portion 124 is formed adjacent to the front end of the transverse wall 13. The lower surface of the locking portion 124 has a locking plane 125 parallel to the top surface 101 (see Figure 10 and Figure 14 ). The guide block 32 and the buckle portion 342 of the second insulating housing 30 are both outwardly protruding from the opposite side surfaces. The guide rail 122 is substantially L-shaped or semi-U-shaped, that is, a non-linear guide rail, and the buckle portion 342 is in the shape of a spring arm and outwardly protrudes a protruding block, the upper surface of which is a supporting plane 344.

[0069] In the assembly of the present embodiment, the second insulating housing 30 of the second connector 3b is inserted into the adapter socket 10T of the top surface of the first connector 1b at an angle greater than or equal to an assembly angle (that is, an angle with the top surface 101). The installation angle is preferably 15 degrees or more, for example, 30 degrees or 45 degrees. In this way, the rear end of the second insulating housing 30 is downward, and the front end is upward, so that the guide block 32 enters the guide rail 122 of the adapter socket 10T. Then, the front end of the second insulating housing 30 is pressed downward, and when the second insulating housing 30 is nearly parallel to the top surface of the first connector 1b, the second insulating housing 30 is pushed in the horizontal direction, that is, parallel to the top surface 101, to the first connector 1b, so that the buckle portion 342 is buckled into the locking portion 124 of the adapter socket 10T to complete the assembly process. That is, after one side edge of the second connector 3b is inserted into the adapter socket 10T, the opposite side edge is inserted into the adapter socket 10T in a rotating manner, and finally moved to the locking position to complete the assembly process of the first connector 1b and the second connector 3b. The pressing action of the assembly process not only makes the first power terminal 20' electrically connected with the second power terminal 40' in the second connector 3b, but also generates a terminal normal force between the first power terminal 20' and the second power terminal 40'. That is, the elastic force of the deformation of the first power terminal 20' and the second power terminal 40' is used to form the terminal normal force. This normal force is transferred to the normal force between the first connector 1b and the second connector 3b, which is mainly borne by the locking plane 125 and the supporting plane 344, as well as the guide block 32 and the bottom of the guide rail 122, so that the first connector 1b and the second connector 3b are buckled to each other due to the static friction force generated by the normal force. After the second connector 3b is inserted into the first connector 1b,Figures 13 to 15 As shown in

[0070] As shown in Figure 10 and Figure 15 As shown in FIG. 1 1, the first power terminal 20' corresponding to the exposed area 14 of the adapter socket 10T can be additionally provided with a conducting bump 25, i.e. the middle portion 23 is provided with a conducting bump 25. Thus, the height of the middle portion 23 of the first power terminal 20' of the exposed area 14 is higher than the height of the middle portion 23 of the other first power terminals 20', and the conducting bump 25 preferably protrudes from the top surface of the exposed area 14. That is, the height of the split contact surface of the first power terminal 20' corresponding to the exposed hole 140 outwardly perpendicular to the first direction (or the top surface 101 of the first insulating housing 10) is higher than the height of the corresponding surface of the other first power terminals 20'.

[0071] The conducting bump 25 and the first power terminal 20' can be integrally formed or connected by welding. In other words, the thickness of the middle portion 23 of the first power terminal 20' corresponding to the exposed area 14 of the adapter socket 10T is greater than the thickness of the middle portion 23 of the first power terminal 20' not corresponding to the exposed area 14.

[0072] The second pin 43 of the second power terminal 40' extends out of the second insulating housing 30 in a direction parallel to the top surface 101. Please refer to Figure 13 , the second connector 3b has two second power terminals, the second pins 43 of which are located at the same position, but the cables C are respectively connected to the upper and lower surfaces of the second pins 43, i.e. the cable connection surfaces of the second pins 4 are staggered with each other, thereby staggering the cables C of the same direction with each other. The upper surface of the second connector 3b has at least one heat dissipation slot 346 (or heat dissipation through hole) to increase the heat dissipation capacity of the second connector 3b.

[0073] [Third Embodiment]

[0074] Please refer to Figure 16 , the third embodiment of the present application provides an electrical connector assembly with a split structure, which comprises a first connector 1c and a second connector 3c. The first connector 1c has a first insulating housing 10 and a plurality of first electrical terminals 20. The second connector 3c has a second insulating housing 30.

[0075] ​The guide block 32 and the snap portion 342 of the second insulating housing 30 are both outwardly protruded on the two side surfaces. The difference from the above embodiment in the structural design is that the guide block 32 is close to the front end of the second insulating housing 30, is substantially L-shaped and outwardly protruded; the snap portion 342 is in the shape of a spring arm and outwardly protrudes a bump, and is close to the rear end of the second insulating housing 30. That is, the guide block 32 and the snap portion 342 formed on the same side surface are close to the other two opposite side surfaces respectively. The guide rail 122 of the limiting side wall 12 is slightly L-shaped and close to the transverse wall 13, and the locking portion 124 is formed on the rear end of the limiting side wall 12 away from the transverse wall 13.

[0076] In the assembly of the present embodiment, the second insulating housing 30 of the second connector 3c is also inserted into the adapter socket 10T on the top surface of the first connector 1c at an angle greater than or equal to an assembly angle. When the angle is less than the assembly angle, the guide block 32 cannot be smoothly slid into the guide rail 122. The difference from the above embodiment is that the front end of the second insulating housing 30 is downward and the rear end is upward. The guide block 32 enters the guide rail 122 of the adapter socket 10T, and then the rear end of the second insulating housing 30 is pressed downward, so that the second insulating housing 30 enters a locking position close to parallel to the top surface of the first connector 1b, and the snap portion 342 is clamped into the locking portion 124 of the adapter socket 10T. The guide block 32 is L-shaped, and in the locking position, the bottom of the guide block 32 has a normal force perpendicular to the top surface of the first connector 1b, so that the second electrical terminal 40 of the second connector 3c and the first electrical terminal 20 of the first connector 1c have a sufficient normal force to reduce the contact resistance therebetween.

[0077] [Fourth Embodiment]

[0078] Referring to Figure 17 The fourth embodiment of the present application provides an electrical connector assembly with a shunt structure, which includes a first connector 1d and a second connector 3d. The first connector 1d has a first insulating housing 10, a plurality of first electrical terminals 20. The second connector 3d has a second insulating housing 30. Most of the present embodiment is the same as the above embodiment. The main difference from the above embodiment is that the first electrical terminal 20 of the first connector 1d is the same as the first embodiment, and the intermediate portion 23 is exposed to the exposed hole 140 of the exposed area 14. Preferably, the height of the intermediate portion 23 of the first electrical terminal 20 located in the exposed area 14 can be higher than the height of the intermediate portion of the first electrical terminal 20 not located in the exposed area 14, preferably the intermediate portion 23 is exposed to the exposed hole 140 of the exposed area 14, so as to reduce the contact resistance between the first electrical terminal 20 and the second electrical terminal 40.

[0079] [Fifth Embodiment]

[0080] Referring to Figures 18 to 19The fifth embodiment of the present application provides a split structure electric connector assembly, which comprises a first connector 1e and a second connector 3e. The first connector 1e has a first insulating housing 10, a plurality of first electric terminals 20. The second connector 3e has a second insulating housing 30.

[0081] The bottom surface of the second insulating housing 30 is rectangular.

[0082] The difference between the above embodiment and the present embodiment is that the adapter socket 10T has two lateral walls 13, two limiting side walls 12 and at least one exposed area 14 which is rectangular. The two lateral walls 13 are connected with the two limiting side walls 12 and enclose the exposed area 14. Each exposed area 14 defines a slot, and the other end of the slot is exposed on the top surface of the first insulating housing (not shown). The adjacent slots are separated by a partition wall 141. In the present embodiment, the partition wall 141 connects the two lateral walls 13 and extends to the top surface of the adapter socket 10T to completely separate the adjacent two slots. That is, the slots are in communication with the input interface and the output interface of the first connector 1e. The length direction of the slot is parallel to the direction of the lateral wall 13. The middle part 23 of the first electric terminal 20 is additionally provided with a fork-shaped contact 26. The fork-shaped contact 26 has a horizontal part 261 and a pair of elastic arms 262. The pair of elastic arms 262 respectively extend upward from both sides of the horizontal part 261 to the slot through the exposed hole. The elastic arms 262 define an insertion space between the side walls, which is parallel to the two long side walls 13. The horizontal part 261 is connected to the middle part 23 of the first electric terminal 20. In addition, the second contact part 42 of the second electric terminal 40 of the second connector 3e is plate-shaped, bent and extends downward from one end of the second connector 3e; that is, the second electric terminal 40 is L-shaped. The second insulating housing 30 additionally forms a pair of blocking walls 36 respectively located on both sides of the second contact part 42, preferably the two long sides, and the second contact part 42 is parallel to the blocking wall 36, that is, parallel to the long side adjacent to the bottom surface of the second insulating housing 30. The locking arm 34 is located on one side of the second connector 3e, preferably the long side.

[0083] In the assembly of the present embodiment, the second connector 3e is inserted into the first connector 1e from top to bottom, the second contact portion 42 on the bottom surface of the second electrical terminal 40 is inserted into the middle of the fork-shaped contact 26 to electrically connect with the pair of elastic arms 262, and the pair of blocking walls 36 are located outside the two long side walls 13. The present embodiment has a different engagement mode from the above embodiments. In the present embodiment, the locking arm 34 is formed in the shape of an elastic arm on the front end surface of the second insulating housing 30 (i.e., the long side of the rectangular second insulating housing 30), and the locking portion 124 is formed in the shape of a protrusion on the front end surface of the first insulating housing 10 (i.e., on the long side wall 13, on the outer surface of the long side wall 13). When the second connector 3e is inserted downward to a locking position, one end (the lower end) of the locking arm 34 can be latched to the locking portion 124. The operator can press the upper end of the locking arm 34 to release the latching state. In order to facilitate the operator to press the locking arm 34, the upper end of the locking arm 34 has a pressing portion 347 extending outwardly (i.e., away from the second connector 3e) from the locking arm 34, i.e., the pressing portion 347 protrudes from the front end surface of the second insulating housing 30, facilitating the operator to confirm the pressing point and the force when pressing. In addition, the second insulating housing 30 also has a recessed space corresponding to the position of the pressing portion 347, which is recessed inwardly from the front end surface of the second insulating housing 30, so that when the operator presses the pressing portion 347 towards the second insulating housing 30, the operator's finger can be accommodated.

[0084] [Sixth Embodiment]

[0085] Referring to Figures 20 to 21 , the sixth embodiment of the present application provides an electrical connector assembly with a shunt structure, which includes a first connector 1f and a second connector 3f. The first connector 1f has a first insulating housing 10, a plurality of first electrical terminals 20'. The second connector 3f has a second insulating housing 30. Similar to the above embodiment, the adapter socket 10T has two transverse walls 13 and two limiting side walls 12 forming a rectangle, and at least one exposed area 14 located therein. Each exposed area 14 defines at least one slot therein. The other end of the slot is connected to the exposed hole. The difference from the above embodiment is that the present embodiment does not use a cable, i.e., instead of using a plurality of conductive fibers, a plate-shaped metal Cf (such as a copper bar) is used to transmit current, which can transmit larger current. One end of the plate-shaped metal Cf is used as a second power terminal 40' in the second connector 3f, and the second contact portion is perpendicular to the bottom surface of the second insulating housing 30 and is used to insert into the slot to be connected with at least one electrical terminal (i.e., the fork-shaped contact 26) of the adapter socket 10T, and to electrically connect with the first power terminal 20 of the first connector 1f. In other words, the second power terminal 40' of the second connector 3f is an extension of the plate-shaped metal Cf, one end of which is used as the second contact portion 42 and is inserted into the corresponding slot of the adapter socket 10T, and the other end is used as the second pin 43 extending out of the second insulating housing 30 but not connected with the cable to be directly connected with the electronic element. Please refer toFigure 20 Since the two slots are located on the same plane, the front end of the second contact portion 42 of the first electrical terminal 20' is also located on the same plane. In order to stagger the same direction of the plate-shaped metal, at least one of the plate-shaped metals Cf has a stepped structure in the direction perpendicular to the plate-shaped surface of the plate-shaped metal (in this embodiment, the direction perpendicular to the slot), so that the plate-shaped metal Cf is staggered at the position perpendicular to the plate-shaped surface. The second pin 43 of the plate-shaped metal Cf has at least one turning portion or is L-shaped, so that the plate-shaped metal Cf can be turned along the two connected side edges of the second insulating housing. In this way, the direction of the plate-shaped metal Cf can be adjusted while minimizing the overall volume of the second connector 3f.

[0086] The locking method of this embodiment is similar to that of the previous embodiment and will not be repeated here.

[0087] [Seventh Embodiment]

[0088] Referring to Figure 22 , the seventh embodiment of the present application provides an electrical connector assembly with a shunt structure, which includes a first connector 1g and a second connector 3g. The first connector 1g has a first insulating housing 10, a plurality of first power supply terminals 20'. The second connector 3g has a second insulating housing 30. One end (the second contact portion 42, located on the bottom surface of the second insulating housing 30) of the plate-shaped second power supply terminal 40' is inserted into the corresponding slot of the adapter socket 10T, and the other end extends out of the rear end surface of the second insulating housing as a second pin 43, which is adjacent to the bottom surface and is preferably perpendicular to it. The difference from the previous embodiment is that one of the two second power supply terminals 40' has two second contact portions 42, one on the left and one on the right of the second contact portion 42 of the other second power supply terminal 40'. The middle second contact portion 42 is inserted into the middle slot, and the left and right second contact portions 42 are inserted into the left and right two slots, respectively, which are separated from the middle slot by a partition wall 141. One of the two second power supply terminals 40' is electrically connected to the power supply potential, and the other is electrically connected to the ground potential, for example: the second power supply terminal 40' with two second contact portions 42 on the sides is electrically connected to the ground potential, and the second power supply terminal 40' with the middle second contact portion 42 is electrically connected to the power supply potential. The long side wall 13 can be provided with at least one guide groove 134, and the second connector 3g has a corresponding guided portion (not shown) on one long side of the rectangular second insulating housing 30. When the second connector 3g is inserted into the adapter socket 10T, the guided portion slides along the guide groove 134 to achieve the positioning effect. The locking method of this embodiment is similar to that of the sixth embodiment and can have multiple sets of locking arms 34 and locking portions 124.

[0089] [Eighth Embodiment]

[0090] Referring toFigures 23 to 25 The eighth embodiment of the present application provides a split structure electrical connector assembly, which comprises a first connector 1h and a second connector 3h. The first connector 1h has a first insulating housing 10, a plurality of first electrical terminals 20. The second connector 3h has a second insulating housing 30. The bottom surface of the second insulating housing 30 is rectangular. The difference from the above embodiments is that the first electrical terminal 20 forms an upward protruding intermediate portion 27 between the first contact portion 21 and the first pin 22. Specifically, the intermediate portion 27 can be a pair of folded metal plates, the two ends of the metal plates are connected to the first contact portion 21 and the first pin 22 respectively, and the middle of the folded metal plates protrudes upward. In other words, the intermediate portion 27 is a single joint and is arranged in the exposed area 14 of the rectangle. At least one slot is defined in the exposed area 14, and two adjacent slots are separated by a separation wall 141. In this embodiment, the height of the separation wall 141 is less than the height of the intermediate portion 27, that is, the separation wall 141 does not extend to the top surface of the adapter socket 10T. The intermediate portion 27 is located in the middle of the corresponding slot, that is, between the two long side walls 13 and parallel to the two long side walls 13. The intermediate portion 27 is sheet-shaped and parallel to the length direction of the slot. In addition, the second contact portion 47 of the second electrical terminal 40 has a plurality of spring arms arranged in two columns to form a fork-shaped structure, and the second contact portion 47 defines a clamping surface to clamp the intermediate portion 27 in the form of a pair of folded plates. The clamping surface is perpendicular to the bottom surface of the second insulating housing and parallel to the long side of the bottom surface of the second insulating housing 30. The long side wall 13 can be provided with at least one guide slot 134 for positioning when the second connector 3h is inserted into the adapter socket 10T. The guide slot 134 and the locking portion 124 are located on the same vertical plane (that is, the guide portion of the second insulating housing 30 and the locking arm 34 are located on the same vertical plane). Alternatively, the guide slot 134 and the locking portion 124 can be located on opposite vertical planes (that is, the guide portion of the second insulating housing 30 and the locking arm 34 are located on opposite vertical planes), which can achieve more stable positioning. The upper portion (top surface, opposite to the bottom surface) of the second connector 3h has a cover 37. That is, the lower portion of the second insulating housing 30 has a rectangular four-side, and the second contact portion 47 is located inside the four sides, and the top portion of the upper portion protrudes the four sides in the horizontal plane to form the cover 37, and the area of the cover 37 is greater than the area of the bottom surface of the second insulating housing 30. Therefore, when the second connector 3h is inserted into the adapter socket 10T, the cover structure can completely cover the exposed area 14, and the rectangular four sides are located inside the adapter socket 10T. That is, the lower portion of the second insulating housing 30 is inserted into the adapter socket 10T, and the rectangular four sides of the second insulating housing 30 are surrounded by the transverse wall 13 and the limiting side wall 12 of the adapter socket 10T. In this way, the connection between the adapter socket 10T and the second insulating housing 30 can be stabilized to achieve the limiting effect.

[0091] It is noted that the second insulating housing 30 can also be without the second electrical terminals 40 and serve as a protective cover for the adapter jack 10T. When the adapter jack 10T does not need to be shunted, the second insulating housing 30 can be inserted into the adapter jack 10T, and the second insulating housing 30 has a cover 37 on the top surface thereof to shield the exposed area 14 or the slots of the adapter jack 10T from dust or from being touched by an operator and causing an electric shock. Moreover, the second insulating housing 30 has a locking arm 34 that can be engaged with the locking portion 124 of the adapter jack 10T to prevent the second insulating housing 30 from being removed.

[0092] [The ninth embodiment]

[0093] Referring to Figures 26 to 28 The ninth embodiment of the present application provides an electrical connector assembly with a shunt structure, which includes a first connector Ik and a second connector 3k. The first connector Ik has a first insulating housing 10, a plurality of first electrical terminals 20. The second connector 3k has a second insulating housing 30.

[0094] Similar to the fifth embodiment, the top surface of the middle portion 23 of the first electrical terminal 20 is additionally provided with a forked contact 26. The forked contact 26 has a horizontal portion 261 and a pair of spring arms 262 extending upwardly from both sides of the horizontal portion 261 to the outside of the exposed hole (i.e., into the adapter jack). The first electrical terminal 20 can be two-piece, and the horizontal portion 261 is connected to the middle portion 23 of the two-piece first electrical terminal 20. In addition, the second contact portion 42 of the second electrical terminal 40 of the second connector 3k is in the form of a plate. After the second connector 3k is inserted into the first connector Ik, the forked contact 26 clamps the plate-shaped second contact portion 42.

[0095] [The tenth embodiment]

[0096] Referring to Figures 29 to 31 The tenth embodiment of the present application provides an electrical connector assembly with a shunt structure, which includes a first connector Im and a second connector 3m. The first connector Im has a first insulating housing 10, a plurality of first electrical terminals 20, a plurality of first signal terminals 50. The second connector 3m has a second insulating housing 30. The first connector Im has two input interfaces, one being a power input interface and the other being a signal input interface. Similarly, the first connector Im also has two output interfaces, one being a power output interface and the other being a signal output interface.

[0097] The power input interface and the signal input interface are both located on the first side of the first connector 1m, and are two independent slots. The plurality of first signal terminals 50 each has a first signal contact portion 51 extending into the slot, i.e., the signal input interface, and a first signal pin 52 extending to the bottom surface 102 of the first insulating housing 10, i.e., the signal output interface. The first signal contact portion 51 and the first signal pin 52 are electrically connected to each other. The first signal terminal 50 is a pin, which is used to transmit a current signal of less than 0.5 A.

[0098] The first insulating housing 10 has a shunt socket 10U. Unlike the above embodiment, in the present embodiment, the shunt socket 10U is separately formed from the first insulating housing 10, and then assembled into one body. The shunt socket 10U has a base which is locked to a third side of the first connector 1m. Specifically, the base of the shunt socket 10U has at least one clamping portion 10U1 on the bottom surface thereof, and the first insulating housing 10 has at least one clamping member 104 corresponding thereto. When the shunt socket 10U and the first insulating housing 10 are assembled into one body, the at least one clamping portion 10U1 and the at least one clamping member 104 are clamped to each other, so that the shunt socket 10U is detachably fixed to the first insulating housing 10. The shunt socket 10U is rectangular, and has a pair of long sides and a pair of short sides. The clamping portion 10U1 is preferably a plurality of clamping portions, which are respectively located on the two short sides or / and the two long sides. It is worth noting that, in the present embodiment, the clamping portion 10U1 is located at the two ends of the short side, and extends downward from the bottom surface of the base, and has a clamping body extending horizontally at the front end, which preferably extends outward.

[0099] A extending wall 106 extends downward from a long side of the base of the shunt socket 10U, and the inner surface of the extending wall 106 abuts against a side surface of the first insulating housing 10. In addition, part of the lower surface of the base of the shunt socket 10U contacts part of the upper surface of the top surface 101 of the first insulating housing 10, which is preferably the lower surface of the other long side relative to the extending wall 106. In this way, when the shunt socket 10U is subjected to external force, part of the external force can be transmitted to the first insulating housing 10, so as to enhance the stability of the shunt socket 10U fixed to the first insulating housing 10. In the present embodiment, the extending wall 106 is located outside the first pin 22 of the first electrical terminal 20, so as to protect the first pin 22.

[0100] The third side of the first connector 1m has at least one shunt hole 105 to expose at least one of the plurality of first power terminals 20 and / or at least one of the plurality of first signal terminals 50. The shunt socket 10U has at least one adapter socket 10T corresponding to the at least one shunt hole 105, i.e. the shunt hole corresponding to the first power terminal 20 and / or the shunt hole 105 corresponding to the first signal terminal 50. Each adapter socket 10T has at least one exposed hole. The shunt socket 10U preferably covers all or part of the shunt holes on the third side, and only exposes the corresponding shunted first power terminal 20 and / or first signal terminal 50 through the exposed hole of the adapter socket 10T, or the first power terminal 20 and / or first signal terminal 50 extends out of the corresponding shunt hole 105. If the adapter socket 10T covers part of the shunt hole, the uncovered part can serve as a heat dissipation hole to increase heat dissipation. The structure of each adapter socket 10T can refer to the description of the above-mentioned embodiments of the second connector 3m, which will not be repeated here.

[0101] It is worth noting that although the second connector in the drawings of the fifth to tenth embodiments of the present application is not specifically shown with heat dissipation grooves or heat dissipation holes, in actual application, at least one heat dissipation groove or heat dissipation hole can be provided on the second insulating housing, preferably parallel or perpendicular to the bottom surface, as in the first to fourth embodiments.

[0102] [Advantages of the embodiments]

[0103] One of the advantages of the present application is that the first connector can supply current to the second connector through the first power terminal, and then to other components that need current through the cable or plate-shaped metal. The present application can supply current through the circuit board or the second connector through a single first connector.

[0104] The above disclosure is only the preferred and feasible embodiments of the present application, and does not limit the claims of the present application.
