Especially for the board terminal current connector, the current is transmitted to the circuit board, and the electronic components on the circuit board are divided by the circuit board to provide the required current. The way of shunting through the circuit board, especially for the supply requirements of large current, not only needs to improve the current carrying capacity of the circuit board, but also causes power loss during the current shunting process through the circuit board.

Therefore, how to improve the supply of board-side electrical connectors by improving the structural design has become an issue to be solved in this technical field.

The technical problem to be solved by this creation is to provide a connector assembly with a shunt structure in view of the deficiencies of the prior art, which can additionally shunt current from a single electrical connector to supply other components, so as to save the space of the electronic device.

In order to solve the above-mentioned technical problems, one of the technical solutions adopted in the present invention is to provide a connector assembly including a first connector and a second connector. The first connector has a first shell and a plurality of first terminals fixed on the first shell. Each of the plurality of first terminals has a first contact portion, a first pin connected to a circuit board, and a middle portion located between the first contact portion and the first pin. When a mating element is inserted, the first connector receives the current provided by the mating element through the plurality of first contact portions. The second connector has a second shell and at least one second terminal fixed on the second shell. Each of the at least one second terminal has a second contact portion. The second contact portion has a plurality of elastic arms arranged oppositely. When the first connector is mated with the second connector, the second contact portion clamps the middle portion of the mated first terminal to receive a part of the current.

One of the beneficial effects of the present invention is that the present invention can make the current of the first connector pass through the first terminal to the second terminal of the second connector, and through a single first connector can pass through the circuit board or the second connector supply current.

In this embodiment, the bottom surface 102 of the first insulating case 10 serves as a power output interface and/or a signal output interface.

The first contact portion 21 of the first electrical terminal 20 in this embodiment is located at the input interface. The plurality of first contact portions 21 may define at least one-sided contact surfaces, which are electrically connected to the counterpart elements when they are inserted.

Referring to FIG. 8 , the second connector 3a of this embodiment is inserted into the adapter socket 10T along a direction perpendicular to the top surface 101 of the first connector 1a. When the second connector 3 a is inserted into the adapter socket 10T, the second contact portion 42 of the second electrical terminal 40 contacts the middle portion 23 of the first electrical terminal 20 . Meanwhile, the second insulating housing 30 is limited between the pair of limiting side walls 12 .

The foot side) extends outward to different positions (that is, the distance from the end of the second pin 43 to the pin side of the second insulating shell 30 is different), so that the two (or more) second pins 43 have different distances. When the connected cables C go in the same direction, their positions are staggered. That is to say, the cable connection surfaces of the two (or more) second electrical terminals 40 are staggered with each other, so that the cables C of the same direction connected to these cable connection surfaces can be staggered. In the embodiment shown in FIG. 4 , the second pin 43 has a bending portion, so that the second pin 43 is bent upward. Please refer to FIG. 7 at the same time, the positions of the bending parts are different from front to back, so that the corresponding cables C run in the same direction, but the positions are different from front to back. Therefore, the same second connector 3a can be easily connected to the same electronic component if the cables C for supplying the power supply potential and the ground potential are provided in the same direction. Or another variant embodiment, the position of the bent portion of the second pin 43 can also be the same, but its upward extending lengths are different, so that the connected cables C can have the same direction by staggering the upper and lower positions. Of course, the plurality of cables C connected to the same second connector 3a are divided into two groups of different directions, left and right, and it is not necessary to consider whether the positions of the cables C need to be staggered. Alternatively, referring to FIG. 3, the top surface of the first insulating housing 10 has two adapter sockets 10T, 10T', and the two connectors (the second connector 3a, the third connector 3a') are respectively inserted into the two adapter sockets 10T and 10T'.

The other end face opposite to the end face. More specifically, the second insulating housing 30 has a body portion 31 , and the positioning portion 312 is formed protrudingly on the front end surface of the body portion 31 . However, the present invention is not limited to this, please refer to FIG. 3 and FIG. 4 , in another exposed area 14, the positioning member 133 of the adapter socket 10T' may protrude from the lateral wall 13 facing the exposed area 14; positioning The portion 314 is recessed on the front end surface of the body portion 31 of the second insulating housing 30 of the third connector 3a'. That is to say, the positioning member on the adapter socket of the present invention and the positioning portion on the second insulating shell can be mutually butted grooves and protruding rails for guiding the second connector 3a and the third connector respectively. 3a' is correspondingly inserted into the adapter socket 10T and the adapter socket 10T'. The positioning members on the adapter sockets 10T and 10T' can be used as foolproof keys, and the difference in shape, position or quantity is used to make them different from each other to achieve a foolproof effect. That is, the positioning member of the adapter socket 10T can only be inserted by the correct second connector 3a, but other connectors (eg, the third connector 3a') have incompatible positioning parts (or positioning members and positioning parts) cannot be docked with each other) and cannot be inserted correctly or completely to achieve a foolproof effect. In this embodiment, the foolproof key is a groove or a convex track. The adapter socket 10T provides a power supply potential and the adapter socket 10T' provides a ground potential, so the second connector 3a is inserted into the adapter socket 10T to provide a power supply potential, and the third connector 3a' is inserted into the adapter socket 10T' to provide a ground potential potential. Through the design of the foolproof key, it can be avoided that the second connector 3a and the third connector 3a' are inserted incorrectly and provide wrong electric potential to the electronic components.

In addition, the latching portion 124 has a latching plane 125 (in the embodiment shown in FIG. 2 , the lower surface of the latching portion 124 ) parallel to the shunt contact surface, so as to provide the second connector 3a with a vertical Due to the normal force of the shunt contact surface, when the second contact portion 42 of the second electrical terminal 40 is in contact with the shunt contact surface of the first electrical terminal, there is sufficient positive force to reduce the contact impedance between the two. The locking arm 34 also has a supporting plane 344 (see FIG. 4 ) corresponding to the locking plane 125 to receive the positive force, and the supporting plane 344 is parallel to the bottom surface of the second insulating housing 30 .

To form a free end, the guide block 32 surrounds a part of the locking arm 34 so as to limit the displacement of the locking arm 34 in the horizontal direction.

The body portion 31 has a pressing portion 311 (refer to FIG. 4 ) whose height is equal to or higher than that of the locking arm 34 . The pressing portion 311 is preferably located on the top surface of the body portion 31 , that is, 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 due to the height of the pressing portion 311 (ie, the pressing plane) The height of the locking arm 34 is not lower than the height of the locking arm 34 to avoid the force exerted by the user during the locking process from affecting the original locking function of the locking arm 34 . As shown in FIG. 4 , the pressing portion 311 extends upward from the middle of the body portion 31 and is located between the two locking arms 34 . The pressing portion 311 may have two or more force-applying members to define a horizontal (ie, parallel to the bottom surface of the second insulating shell 30 ) pressing plane, so as to avoid uneven force on the left and right sides when the user exerts force The problem.

The adapter socket 10T (ie, the second insulating shell) may have a heat dissipation slot or a heat dissipation through hole running through the front and rear, so as to increase the overall heat dissipation capability of the adapter socket 10T itself and the connector assembly. Heat sinks or thermal vias can be vertical (to the PCB board) or parallel (to the PCB board) design. When designed vertically, the heat dissipation can be enhanced due to the upward effect of thermal convection; when designed in parallel, the horizontal airflow generated by the fan of the system (for example, the server) where the adapter socket 10T is located can be blown in or blown in. The heat dissipation is enhanced by taking away the generated heat through horizontal (that is, parallel with the PCB board, that is, the bottom surface of the second insulating shell) heat dissipation grooves or heat dissipation through holes. , and the heat dissipation slot or the heat dissipation through hole can also increase the surface area of the adapter socket 10T itself and the connector assembly, and also have the function of increasing the heat dissipation capacity.

The pair of inner limiting grooves 310 are located inside the guide block 32 . In this way, the displacement of the locking arm 34 in the horizontal direction or the vertical direction can be properly protected to prevent the locking arm 34 from being damaged by improper external force.
