[0023] The following will further describe a double-tongue contactless connector in this exemplary embodiment.

[0024] In one embodiment of this application, the first conductive spring 31 includes: a first contact portion 311, a second contact portion 312, and a first insertion portion 313; The first plug-in portion 313 mates with the plate end assembly 1; the first contact portion 311 is disposed at the bottom of the first plate end tongue 11; the second contact portion 312 is disposed at the top of the second plate end tongue 12; When the plate end assembly 1 and the line end assembly 2 are connected, the first contact portion 311 and the second contact portion 312 are electrically connected to the first terminal 41 respectively.

[0025] It should be noted that the first insertion part 313 can be inserted into the side wall of the plate end assembly 1 through the protrusion 3131 to improve the stability of the installation of the first conductive spring 31.

[0026] In one embodiment of this application, the second conductive spring 32 includes: a third contact portion 321, a fourth contact portion 322, and a second insertion portion 323; The second plug-in portion 323 cooperates with the plate end assembly 1; the third contact portion 321 is disposed at the bottom of the second plate end tongue 12; the fourth contact portion 322 is disposed at the bottom of the plate end assembly 1 on the side close to the second plate end tongue 12. When the plate end assembly 1 and the line end assembly 2 are connected, the third contact portion 321 and the fourth contact portion 322 are electrically connected to the second terminal 42 respectively.

[0027] It should be noted that both the first conductive spring 31 and the second conductive spring 32 are connected to the corresponding conductive terminals with two contacts, one above the other, which has high vibration resistance. At the same time, the dual-contact current transmission can further ensure the stability of contact impedance and has better current carrying capacity.

[0028] In one embodiment of this application, the first wire end tongue 21 is provided with a plurality of terminal receiving slots 211; the first terminals 41 are respectively disposed on the inner side of the terminal receiving slots 211; The first terminal 41 is provided with a terminal guide groove 411, and the terminal receiving groove 211 is provided with a limiting guide strip 2111 corresponding to the terminal guide groove 411; When the plate end assembly 1 and the line end assembly 2 are connected, the limiting guide strips 2111 are correspondingly inserted into the terminal guide grooves 411.

[0029] It should be noted that the terminal is limited by the cooperation structure between the limiting guide strip 2111 and the terminal guide groove 411, which ensures the stability of the terminal installed on the corresponding tongue.

[0030] As an example, the second terminal tongue 22 can also accommodate the second terminal 42 through a similar receiving groove structure, and limit the guide groove of the second terminal 42 through a similar guide bar structure.

[0031] In one embodiment of this application, a terminal latching member 2112 is provided on the inner side of the terminal receiving groove 211; a terminal fastener 412 is provided on the outer side of the first terminal 41; the terminal fastener 412 and the terminal latching member 2112 are correspondingly engaged.

[0032] It should be noted that the locking and limiting structure of the terminal clip 412 and the terminal clip 2112 further ensures the stability of the terminal installation on the corresponding tongue.

[0033] As an example, the snap-fit ​​structure of the second terminal 42 can also be limited by the snap-fit ​​structure of the receiving groove of the second line end tongue 22.

[0034] In one embodiment of this application, the top of the plate end assembly 1 is provided with a snap-fit ​​portion 15, and a third receiving cavity 16 is formed between the snap-fit ​​portion 15 and the first plate end tongue 11; the top of the wire end assembly 2 is provided with a latching portion 23. When the plate end assembly 1 and the wire end assembly 2 are connected, the other end of the latching part 23 is embedded in the third receiving cavity 16 and is limited and engaged with the latching part 15.

[0035] It should be noted that the locking and limiting structure of the snap-fit ​​part 15 and the snap-fit ​​part 23 ensures the stability of the installation between the board end assembly 1 and the wire end assembly 2.

[0036] In one embodiment of this application, the snap-fit ​​portion 15 is provided with two snap-fit ​​guide posts 151 on the side near the first plate end tongue 11; When the plate end assembly 1 and the line end assembly 2 are connected, the two snap-fit ​​guide posts 151 are respectively disposed on both sides of the snap-fit ​​part 23.

[0037] It should be noted that the snap-fit ​​part 23 is limited by the snap-fit ​​guide post 151, which facilitates positioning and prevents mistaken insertion during installation.

[0038] In one embodiment of this application, limiting protrusions 231 are provided on both sides of the buckle portion 23; When the plate end assembly 1 and the line end assembly 2 are connected, the two limiting protrusions 231 respectively abut against the ends of the two snap-fit ​​guide posts 151.

[0039] It should be noted that the limiting protrusion 231 abutting against the end of the snap-fit ​​guide post 151 can prevent the wire end assembly 2 from being over-inserted into the plate end assembly 1, and at the same time effectively utilize the structure of the snap-fit ​​guide post 151.

[0040] In one embodiment of this application, the top of the first plate end tongue 11 is provided with a plurality of limiting grooves 111; the bottom of the buckle part 23 is provided with a plurality of limiting protrusions 232 corresponding to the limiting grooves 111. When the plate end assembly 1 and the line end assembly 2 are connected, the plurality of limiting grooves 111 and the plurality of limiting protrusions 232 are matched one-to-one.

[0041] It should be noted that the first plate end tongue 11, the second plate end tongue 12, the first wire end tongue 21, and the second wire end tongue 22 can cooperate with each other through the grooves respectively provided on each tongue, which further improves the firmness of the mating between the plate end assembly 1 and the wire end assembly 2.

[0042] In one embodiment of this application, positioning holes 17 are provided on both sides of the plate end assembly 1; positioning pieces 5 are provided inside the positioning holes 17. The line end assembly 2 has abutment portions 24 on both sides corresponding to the plate end assembly 1, and the abutment portions 24 have heat dissipation holes 241.

[0043] It should be noted that the board end assembly 1 can be mounted on the target substrate by means of the positioning piece 5. The shape of the positioning hole 17 corresponds to that of the positioning piece 5. Setting the positioning hole 17 as a sheet-like hole can increase the stability of the board end assembly 1 during installation.
