[0022] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following description is based on the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Please see Figure 1 An embodiment of the present invention provides an electrical connector 100 for mating a first circuit board and a second circuit board (not shown). The electrical connector 100 includes a first insulator 10, a second insulator 20, and at least one conductive terminal 40. The first insulator 10 is independent of the second insulator 20. The first insulator 10 is used to mat with the first circuit board, and the second insulator 20 is used to mat with the second circuit board. The conductive terminal 40 is held to the first insulator 10 and the second insulator 20 and electrically connects the first circuit board and the second circuit board to transmit signals between the first circuit board and the second circuit board.

[0024] The first insulator 10 has a first mating surface 11, and the second insulator 20 has a second mating surface 21. Please refer to... Figure 2Each conductive terminal 40 includes a first contact portion 41, a first fixing portion 42, an extension portion 43, a second fixing portion 44, and a second contact portion 45 connected in sequence. The first fixing portion 42 is fixed to the first insulator 10, and the second fixing portion 44 is fixed to the second insulator 20. The first contact portion 41 extends from the first fixing portion 42 and is partially exposed on the first mating surface 11, and the second contact portion 45 extends from the second fixing portion 44 and is partially exposed on the second mating surface 21. The first mating surface 11 faces and abuts against the first circuit board, and the second mating surface 21 faces and abuts against the second circuit board, so that the first contact portion 41 electrically contacts the first circuit board, and the second contact portion 45 electrically contacts the second circuit board.

[0025] Please combine Figure 1 and Figure 2 The extension 43 is connected to the first fixing part 42 and the second fixing part 44, and is deformably located between the first insulator 10 and the second insulator 20. When the first circuit board, the second circuit board and the electrical connector 100 are in a vibrating environment, the first circuit board and the second circuit board will move relative to each other. The first insulator 10, the first fixing part 42 and the first contact part 41 move together with the first circuit board, so that the first contact part 41 maintains an electrical connection with the first circuit board; the second insulator 20, the second fixing part 44 and the first contact part 41 move together with the second circuit board, so that the second contact part 45 maintains an electrical connection with the second circuit board. Thus, when the first circuit board and the second circuit board move relative to each other, the first insulator 10 and the second insulator 20 will also move relative to each other. The extension 43 provides a displacement distance by deforming itself to prevent the first fixing part 42 and the second fixing part 44 from pulling the first contact part 41, causing poor contact between the first contact part 41 and the first circuit board, and / or pulling the second contact part 45, causing poor contact between the second contact part 45 and the second circuit board. It also prevents the electrical connector 100 from being damaged by pulling the conductive terminal 40 during the movement of the first insulator 10 and the second insulator 20, thereby enabling the electrical connector 100 to be used and transmit signals in a vibrating environment. Electrically connecting the first circuit board and the second circuit board with a single electrical connector 100 simplifies assembly and reduces the risk of connection failure that can easily occur when multiple electrical connectors 100 are interchanged, ensuring a reliable connection between the electrical connector 100 and the first and second circuit boards.

[0026] In some embodiments, the first mating surface 11 is provided with a first positioning post 111 and a first connecting hole 112, and the second mating surface 21 is provided with a second positioning post 211 and a second connecting hole 212. Both the first connecting hole 112 and the second connecting hole 212 are configured as connecting fasteners. Both the first circuit board and the second circuit board are provided with a first mating hole corresponding to the first positioning post 111 or the second positioning post 211, and a second mating hole corresponding to the first connecting hole 112 and the second connecting hole 212. In use, the first circuit board is first positioned by the first positioning post 111, or the second circuit board is positioned by the second positioning post 211. Then, the first circuit board or the second circuit board is locked by fasteners. When the first positioning post 111 is inserted into the first mating hole of the first circuit board, the first connecting hole 112 corresponds to the second mating hole of the first circuit board. The fastener can pass through the corresponding first connecting hole 112 and second mating hole to fix the first circuit board to the first mating surface 11. When the second positioning post 211 is inserted into the first mating hole of the second circuit board, the second connecting hole 212 corresponds to the second mating hole of the second circuit board. Fasteners can pass through the corresponding second connecting hole 212 and second mating hole to fix the second circuit board to the second mating surface 21. The fasteners include bolts, screws, screws, or threaded rods. The first connecting hole 112 and the second connecting hole 212 can be disposed through the first insulator 10 or the second insulator 20. The number of the first positioning post 111, the first connecting hole 112, the second positioning post 211, and the second connecting hole 212 can be two or more.

[0027] In some embodiments, the first insulator 10 has a first suction surface 12 facing away from the first mating surface 11, and the second insulator 20 has a second suction surface 22 facing away from the second mating surface 21. The first mating surface 11 and the second mating surface 21 are parallel to each other, and both the first suction surface 12 and the second suction surface 22 are parallel to the first mating surface 11. The vacuum suction head can adsorb the first suction surface 12 or the second suction surface 22 to pick up the first insulator 10 or the second insulator 20 and move them, facilitating the transfer of the first insulator 10 to the top of the first circuit board or the transfer of the second insulator 20 to the top of the second circuit board for assembly.

[0028] Please see Figure 3 and Figure 4 In some embodiments, both the first mating surface 11 and the second mating surface 21 are provided with fixing grooves 14, which are configured to accommodate the first fixing part 42 or the second fixing part 44. Each of the widths of the first fixing part 42 and the second fixing part 44 has a locking block 46 extending from both sides. The locking block 46 engages with the corresponding fixing groove 14 to position the first fixing part 42 and the second fixing part 44 into the corresponding fixing groove 14 along the second direction Z. The second direction Z is parallel to the vertical direction.

[0029] Both the first insulator 10 and the second insulator 20 are provided with through slots 15. Both the first fixing part 42 and the second fixing part 44 have upwardly extending protrusions 47, which insert into the corresponding through slots 15 to position the first fixing part 42 and the second fixing part 44 horizontally. By engaging the locking block 46 with the fixing slot 14 and the protrusions 47 with the through slots 15, the first fixing part 42 can be fixed to the first insulator 10, and the second fixing part 44 can be fixed to the second insulator 20.

[0030] Please see Figure 4 In some embodiments, the end of the first contact portion 41 passes upward through the side wall of the fixing groove 14 and overlaps with the first insulator 10, and the end of the second contact portion 45 passes upward through the side wall of the fixing groove 14 and overlaps with the second insulator 20, so as to position the ends of the first contact portion 41 and the second contact portion 45.

[0031] In some embodiments, the first insulator 10 is provided with a first receiving groove 16, which is connected to a corresponding fixing groove 14 to receive a portion of the extension 43; the second insulator 20 is provided with a second receiving groove 24, which is connected to a corresponding fixing groove 14 to receive a portion of the extension 43.

[0032] Please combine Figure 4 and Figure 5 In some embodiments, the extension 43 includes a third fixing portion 431, a first curved portion 432 extending from one end of the third fixing portion 431, and a second curved portion 433 extending from the other end of the third fixing portion 431. The first curved portion 432 is connected to the first fixing portion 42, and the second curved portion 433 is connected to the second fixing portion 44. The first curved portion 432 is located in the first receiving groove 16, and the second curved portion 433 is located in the second receiving groove 24. Both the first curved portion 432 and the second curved portion 433 extend along the second direction Z and bend along the first direction X, so that the extension 43 can deform along the first direction X and the second direction Z. Wherein, the first direction X is perpendicular to the second direction Z, the second direction Z is the height direction of the electrical connector 100, and the first direction X is the spacing direction of the first insulator 10 and the second insulator 20. When the first insulator 10 and the second insulator 20 move relative to each other along the first direction X or the second direction Z, both the first curved portion 432 and the second curved portion 433 can deform, so that the first curved portion 432 and the second curved portion 433 are partially straightened. The conductive terminal 40 is made of metal, and the extension 43 can spring back after deformation.

[0033] In some embodiments, the third fixing portion 431 extends horizontally along a first direction X. The electrical connector 100 also includes a third insulator 30. The third insulator 30 is independent of the first insulator 10 and the second insulator 20. The third fixing portion 431 is fixed to the third insulator 30 such that the third insulator 30 covers the extension portion 43 to protect the extension portion 43 and prevent wear or damage to the extension portion 43.

[0034] Please combine Figure 2 The first insulator 10 has a first groove 13, the second insulator 20 has a second groove 23, and the third insulator 30 includes a first protrusion 31 and a second protrusion 32. The first protrusion 31 can be inserted into the first groove 13 along a first direction X and can move within the first groove 13 along a second direction Z; the second protrusion 32 can be inserted into the second groove 23 along the first direction X and can move within the second groove 23 along the second direction Z, so that the third insulator 30 can move relative to the first insulator 10 and the second insulator 20. When the first insulator 10 and the second insulator 20 move relative to each other along the first direction X, the depth of the first protrusion 31 inserted into the first groove 13 changes, and the depth of the second protrusion 32 inserted into the second groove 23 changes; when the first insulator 10 and the second insulator 20 move relative to each other along the second direction Z, the first protrusion 31 can move within the first groove 13, and the second protrusion 32 can move within the second groove 23.

[0035] Please see Figure 6 In another embodiment of the invention, the extension 43 includes a conductor 48, the two ends of which are respectively attached to the ends of the first fixing part 42 and the second fixing part 44. The length of the conductor 48 is configured to be greater than the distance between the first insulator 10 and the second insulator 20, so that the conductor 48 can straighten or bend during relative movement of the first insulator 10 and the second insulator 20.

[0036] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of the present invention fall within the scope of the present invention.
