[0064] like Figure 1 and Figure 5As shown, the first outward expansion portion 12 and the second outward expansion portion 22 are stacked along the docking direction, that is, the first outward expansion portion 12 and the second outward expansion portion 22 protrude in the second direction relative to the first main body portion 11 and the second main body portion 21 respectively, thereby reducing the space occupied by the first outward expansion portion 12 and the second outward expansion portion 22. At the same time, the first surface 121 and the third surface 221 are in planar contact and cooperation, so that the bearing area of ​​the contact between the first shell 1 and the second shell 2 is increased, thereby reducing the risk of damage due to force.

[0065] like Figure 5 , Figure 6 and Fig. 9 As shown, the second shell 2 also includes a plurality of second terminal holes 23 and a plurality of second stop portions 24. The plurality of second terminal holes 23 are arranged in a plurality of rows in the first direction, and each row of the second terminal holes 23 is aligned along the second direction, and the plurality of the conductive terminals 3 are accommodated in the plurality of the second terminal holes 23 in a one-to-one correspondence. Each of the second terminal holes 23 penetrates the second shell 2 along the docking direction, and each of the conductive terminals 3 is inserted into the corresponding second terminal hole 23 from the second end side 2b toward the second docking end 2a in the docking direction. The second fixing portion 332 is fixed to the second shell 2 by means of an interference fit with the second terminal hole 23. Each of the intermediate sections 333 is clearance-fitted with the corresponding first terminal hole 13 and the corresponding second terminal hole 23 (see Fig. 9 ).

[0066] like Figure 5 and Figure 6 As shown, each second terminal hole 23 is provided with two second stop portions 24 corresponding to the two second limit portions 335, and the second stop portions 24 stop the corresponding second limit portions 335 to prevent the conductive terminal 3 from being excessively inserted into the second housing 2. In other embodiments, each second terminal hole 23 may also be provided with only one second stop portion 24 or more than two second stop portions 24, and the specific number of the second stop portions 24 is not limited here, and can be set according to actual needs, and the number of the second stop portions 24 corresponds to the number of the second limit portions 335.

[0067] like Figure 5 and Fig. 9As shown, the second housing 2 further includes a plurality of second partition ribs 25 and a plurality of second partition fences 26, each of the second partition ribs 25 is disposed between two adjacent second terminal holes 23 in each row, the second partition ribs 25 are spaced apart from the second end side 2b in the docking direction, and the end of the second partition rib 25 facing the second end side 2b in the docking direction is closer to the second docking end 2a than the second end side 2b. The width of the second partition rib 25 gradually decreases in the docking direction from the position corresponding to the second limiting portion 335 toward the direction close to the second end side 2b. Specifically, the size of the first partition rib 15 in the second direction gradually decreases in the docking direction from the position corresponding to the second limiting portion 335 toward the direction close to the second end side 2b.

[0068] like Figure 5 and Fig.12 As shown, a second partition 26 is provided between each of two adjacent rows of the second terminal holes 23, the width of the second partition 26 in the first direction is greater than the width of the second partition rib 25 in the second direction, the second partition 26 is closer to the second end side 2b than the second partition rib 25 in the docking direction, the second partition 26 extends to the second end side 2b, and the first partition 16 is in contact with the second partition 26 (as shown in FIG. Figure 8 ).

[0069] like Figure 1 and Figure 2 As shown, the first connector 200 includes a first base 4, a plurality of first docking terminals 5, two protective plates 6 and two guide grooves 7. The plurality of first docking terminals 5 are accommodated in the first base 4. The first base 4 has a first mating end 41 arranged facing the first docking end 1a. The guide groove 7 is a through groove that passes through the first connector 200 in the docking direction.

[0070] like Figure 1 and Figure 2 As shown, the two guard plates 6 are located on opposite sides of the first base 4 in the first direction and are connected to the first base 4, each guard plate 6 surrounds one side of the first base 4 in the second direction and forms a corresponding guide groove 7, and the guard plate 6 protrudes from the first mating end 41 in the docking direction. The distance that the guard plate 6 protrudes from the first mating end 41 in the docking direction is defined as a third distance D3, and the third distance D3 is greater than the second distance D2.

[0071] like Figure 2 and Figure 3As shown, when the adapter connector 100 is plugged and matched with the first connector 200, the multiple first docking portions 31 pass through the first mating end 41 in the mating direction and contact with the multiple first docking terminals 5 one by one, thereby electrically connecting the first connector 200 to the adapter connector 100, the first docking end 1a and the first mating end 41 are spaced apart in the mating direction to form a heat dissipation space Q, the two guide pillars 17 are inserted along the mating direction and accommodated in the corresponding two guide grooves 7, each of the guide pillars 17 is gap-matched with the corresponding guide groove 7, and the two guide grooves 7 are connected with the heat dissipation space Q in the first direction, the minimum spacing between the first docking end 1a and the first mating end 41 in the mating direction is greater than the spacing between the guide pillars 17 and the first circuit board 400 in the mating direction, so that when the adapter connector 100 is over-inserted into the first connector 200 and causes the guide pillars 17 to abut against the first circuit board 400, there is still a gap between the first docking end 1a and the first mating end 41 in the mating direction, which is conducive to air entry for heat dissipation.

[0072] like Figure 1 and Figure 2 As shown, the second connector 300 includes a second base 8 and a plurality of second docking terminals 9 accommodated in the second base 8, the plurality of second docking terminals 9 are arranged one-to-one correspondingly with the plurality of conductive terminals 3, and the plurality of second docking portions 32 extend into the second base 8 and contact with the plurality of second docking terminals 9 accordingly, thereby electrically connecting the adapter connector 100 to the second connector 300.

[0073] The adapter connector and connector assembly of the utility model also have the following beneficial effects:

[0074] 1. By setting the shell part of the adapter connector 100 into two split structures arranged opposite to each other, the first fixing portion 331 is fixed to the first shell 1, and the second fixing portion 332 is fixed to the second shell 2, so that the first shell 1 can be offset relative to the second shell 2 in a direction perpendicular to the mating direction, and at least a part of the middle portion 33 moves in a direction perpendicular to the mating direction, so that the space in which the conductive terminal 3 can be offset in the first shell 1 and the second shell 2 is increased, that is, the tolerance space of the adapter connector 100 is increased, and when the first connector 200 and the second connector 300 are misaligned in the mating direction, the adapter connector 100 can also be smoothly docked with the first connector 200 and the second connector 300, thereby ensuring the stable transmission of signals and currents between the adapter connector 100 and the first connector 200 and the second connector 300.

[0075] 2. The second end side 2 b keeps in contact with the first end side 1 b , so that the middle portion 33 is circumferentially shielded by the first shell 1 and the second shell 2 , preventing dust or other impurities from entering and affecting the performance of the adapter connector 100 .

[0076] 3. The first shell 1 is provided with the first outward expansion portion 12, which protrudes outward relative to the first main body portion 11 in a direction perpendicular to the mating direction. The second shell 2 is provided with the second outward expansion portion 22, which protrudes outward relative to the second main body in a direction perpendicular to the mating direction, so as to provide space for applying force when the adapter connector 100 is plugged in and out of the first electrical connector 200 and the second connector 300.

[0077] 4. The first outward expansion portion 12 and the second outward expansion portion 22 are stacked along the docking direction, so that the contact area between the first shell 1 and the second shell 2 is increased, reducing the risk of damage by force, and the first outward expansion portion 12 and the second outward expansion portion 22 protrude in different directions relative to each other, which can reduce the space occupied by the adapter connector 100.

[0078] 5. The first stopping portion 14 is provided on the first shell 1, and the first stopping portion 14 stops the first limiting portion 334 in the mating direction to prevent the conductive terminal 3 from being excessively inserted into the first shell 1. The second stopping portion 24 is provided on the second shell 2, and the second stopping portion 24 stops the second limiting portion 335 in the mating direction to prevent the conductive terminal 3 from being excessively inserted into the second shell 2.

[0079] 6. The middle section 333 is clearance-fitted with the first terminal hole 13 and the second terminal hole 23, and there is movable space in the first terminal hole 13 and the second terminal hole 23, so that when the first connector 200 and the second connector 300 are misaligned in the docking direction, the middle section 333 absorbs the docking deviation caused by the misalignment by moving in the space, so that the adapter connector 100 can be smoothly docked with the first connector 200 and the second connector 300 without damaging the terminal structure and the shell structure.

[0080] 7. Since the first housing 1 is a longitudinal structure in the mating direction and the spacing between two adjacent conductive terminals 3 in the same row is small, the first partition rib 15 does not extend to the first end side 1b in the mating direction or is closer to the first end side 1b than the first partition fence 16, which facilitates the molding of the first partition rib 15. The spacing between the conductive terminals 3 in two adjacent rows in the first direction is large, and the width of the first partition fence 16 is greater than that of the first partition rib 15 and extends to the first end side 1b, which strengthens the strength of the first housing 1 and facilitates the molding of the first partition fence 16. Similarly, since the second shell 2 is a longitudinal structure in the mating direction and the spacing between two adjacent conductive terminals 3 in the same row is small, the second partition rib 25 does not extend to the second end side 2b in the mating direction or is closer to the second end side 2b than the second partition fence 26, which facilitates the molding of the second partition rib 25. The spacing between the two adjacent rows of conductive terminals 3 in the first direction is larger, and the width of the second partition fence 26 is greater than the width of the two partition ribs 25 and extends to the second end side 2b, thereby enhancing the strength of the second shell 2 and facilitating the molding of the second partition fence 16.

[0081] 8. The width of the first partition rib 15 gradually decreases in the mating direction from the position corresponding to the first limiting portion 334 toward the first end side 1b, and the width of the second partition rib 25 gradually decreases in the mating direction from the position corresponding to the second limiting portion 335 toward the second end side 2b, thereby gradually increasing the movable space of the conductive terminal 3 in the first terminal hole 13 and the second terminal hole 23 along the width direction of each partition rib.

[0082] 9. The first partition 16 extends to the first end side 1b, and the second partition 26 extends to the second end side 2b. The first partition 16 and the second partition 26 are in contact and cooperate with each other, thereby increasing the contact area between the first shell 1 and the second shell 2 and reducing the risk of damage due to force.

[0083] The above detailed description is only an explanation of the preferred embodiment of the utility model, and does not limit the patent scope of the utility model. Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
