Specifically, in the terminal assembly 100, the terminal body 110 and the card 200 are electrically connected by inserting the card 200 into the terminal body 110, and in order to further improve the stability of the electrical connection between the terminal body 110 and the card 200, the reed 120 is provided between the card 200 and the terminal body 110, and the reed 120 is provided with a plurality of terminal body contacts 122a and a plurality of card contacts 122b, so that the plurality of terminal body contacts 122a and the terminal body 110 are simultaneously connected, and the plurality of card contacts 122b and the card 200 are simultaneously connected, and the current between the terminal body 110 and the card 200 is transmitted through a plurality of parallel current transmission paths formed between the plurality of terminal body contacts 122a and the plurality of card contacts 122b. To simultaneously transmit current in parallel, to improve the current carrying capacity of the terminal assembly 100, thereby satisfying the transmission requirement of large current.

In some embodiments, the plurality of terminal body contacts 122a and the plurality of card contacts 122b of leaf spring 120 are alternately arranged along the extending direction of card 200. By alternately arranging the plurality of terminal body contacts 122a and the plurality of card contacts 122b of the reed 120, the situation that no current is transmitted to one terminal body contact 122a or one card contact 122b is avoided, and the current transmission effect between the plurality of terminal body contacts 122a and the plurality of card contacts 122b is ensured.

In some embodiments, spring 120 includes a current carrying contact 122, current carrying contact 122 disposed between terminal body 110 and insert 200, a plurality of terminal body contacts 122a disposed on one side of current carrying contact 122, and a plurality of insert contacts 122b disposed on the other side of current carrying contact 122 to electrically connect with terminal body 110 and insert 200, respectively, through terminal body contacts 122a and insert contacts 122b disposed on both sides of current carrying contact 122.

In some embodiments, the current carrying contact 122 includes a plurality of bent portions 122d and a plurality of connecting portions 122e, the plurality of bent portions 122d and the plurality of connecting portions 122e are alternately connected, the terminal body contact 122a is disposed on the bent portion 122d near the terminal body 110, and the card contact 122b is disposed on the bent portion 122e near the card 200. By arranging the current-carrying contact 122 in a multi-bending structure, the current-carrying contact 122 has a plurality of contacts, so as to ensure the current transmission effect of the current-carrying contact 122. The multi-fold structure may be wave-shaped, delta-fold, rectangular-fold, etc., which is not limited in this embodiment. In the embodiment of the present application, as shown in fig. 3, the multi-bending structure of the current-carrying contact 122 is wave-shaped, wherein the current-carrying contact 122 has three terminal body contacts 122a and two card contacts 122b.

Of course, the protrusions on the current-carrying contact 122 near the terminal body 110 may be the terminal body contact 122a, and the protrusions on the current-carrying contact 122 near the package 200 may be the package contact 122b by alternately arranging the protrusions on the main body of the current-carrying contact 122, which is not limited in this embodiment.

In some embodiments, among the plurality of bent portions 122d and the plurality of connecting portions 122e that are alternately connected, one of the two bent portions 122d connected to the same connecting portion 122e is provided with the terminal body contact 122a, and the other is provided with the card contact 122b, so that the plurality of bent portions 122d and the plurality of connecting portions 122e form an alternately arranged structure on the current carrying contact 122.

In some embodiments, in order to further ensure the current transmission effect of the current-carrying contact 122, two bending portions 122d connected to the same connecting portion 122e are arranged in a staggered manner in the plurality of bending portions 122d and the plurality of connecting portions 122e that are alternately connected to each other, so that the plurality of terminal body contacts 122a and the plurality of card contacts 122b are alternately arranged along the extending direction of the card 200, and no current transmission is avoided for a certain terminal body contact 122a or a certain card contact 122b.

In some embodiments, current carrying contacts 122 are provided on both sides within the terminal body 110, and the insert 200 is interposed between the two side current carrying contacts 122 within the terminal body 110. Because the current-carrying contact 122 has a multi-bending structure and a certain elasticity, when the plug 200 is inserted into the terminal body 110, the plug 200 can bend the current-carrying contact 122 on both sides in the reed housing 121 back to abut against the inner wall of the terminal body 110 as the plug 200 is inserted between the current-carrying contacts 122 on both sides in the terminal body 110.

In addition, the current-carrying contact 122 has a plurality of contacts, that is, the plug 200 is sandwiched between the plurality of plug contacts 122b of the current-carrying contact 122 on both sides in the terminal body 110, so that the positive pressure between the plug 200 and the current-carrying contact 122 can be reduced, and the connection stability between the plug 200 and the terminal body 110 can be maintained. Because the abutting force between the plug 200 and the current-carrying contact 122 is reduced, the plug force between the plug 200 and the terminal body 110 is correspondingly reduced, thereby reducing the damage of the current-carrying contact 122 to the surface coating of the plug 200 and improving the operation feeling of staff.

In some embodiments, as shown in fig. 3, the current carrying contact 122 is fixedly connected to the terminal body 110, i.e., the current carrying contact 122 is fixedly disposed inside the terminal body 110, thereby facilitating connection of the terminal body 110 to the insert 200. Of course, the current-carrying contact 122 may be fixedly connected to the interposer 200, which is not limited in this embodiment.

As shown in fig. 3, current-carrying contacts 122 are disposed at intervals on both sides in the reed housing 121, that is, there is a gap between the current-carrying contacts 122 disposed on both sides in the reed housing 121, and there is a gap between the current-carrying contacts 122 and the inner wall of the reed housing 121, so that when the terminal body 110 is plugged onto the reed 120, the outer wall of the terminal body 110 is connected with the inner wall of the reed housing 121, and the current-carrying contacts 122 are disposed inside the terminal body 110, that is, both sides in the terminal body 110 are provided with the current-carrying contacts 122.

In some embodiments, as shown in fig. 8, the reed 120 further includes a connecting piece 123, one end of the reed housing 121 far away from the terminal body 110 is connected to one end of the current-carrying contact 122 far away from the terminal body 110 through the connecting piece 123, and one end of the current-carrying contact 122 near the terminal body 110 is suspended, so as to enclose a slot 122f configured for plugging the terminal body 110 through the reed housing 121, the connecting piece 123 and the current-carrying contact 122. Further, the connecting piece 123 is of a bent structure, the current-carrying contact 122 is disposed inside the reed housing 121 through the connecting piece 123, and one end of the current-carrying contact 122, which is not connected to the connecting piece 123, is suspended, so as to ensure the elasticity of the current-carrying contact 122.

It should be noted that, the elasticity of the current-carrying contact 122 mainly means elasticity in two aspects, on the one hand, the suspension structure is adopted by the current-carrying contact 122, so that the whole current-carrying contact 122 has elasticity; on the other hand, due to the abutting force between the card 200 and the current-carrying contact 122, the current-carrying contact 122 is elastically deformed, that is, the relative distance between the terminal body contact 122a and the card contact 122b on the current-carrying contact 122 is reduced.

In some embodiments, as shown in fig. 4, the terminal body 110 includes a plugging end 111 and a terminal 112, wherein the plugging end 111 of the terminal body 110 is plugged into the slot 122f and electrically connected with the current-carrying contact 122, and the terminal 112 of the terminal body 110 is used for connecting with a wire, so that the connection of the wire and the reed 120 on the terminal body 110 is realized through the plugging end 111 and the terminal 112 of the terminal body 110, respectively, and the functionality of the terminal body 110 is ensured.

In the present embodiment, the snaps 121a are provided at four corners of the end of the reed housing 121 near the one end of the terminal body 110.

In some embodiments, as shown in fig. 4, the terminal 112 of the terminal body 110 includes a conductive crimp 112a and an insulating crimp 112b, the conductive crimp 112a being closer to the mating end 111 of the terminal body 110 than the insulating crimp 112 b. When the wire is mounted on the terminal 112 of the terminal body 110, the conductive crimp portion 112a and the insulating crimp portion 112b simultaneously compress the wire, typically, the insulating crimp portion 112b is used to crimp an external insulating layer of the wire, and the conductive crimp portion 112a is used to crimp an internal core of the wire, so as to ensure control of crimp quality and improve efficiency of the crimping process. In addition, a plurality of grooves 112c are formed on the inner surface of the conductive crimp portion 112a at intervals, so as to improve the reliability of crimping the conductive crimp portion 112a to the conductive wire and ensure the conductivity of the terminal assembly 100 and the conductive wire.
