[0043] like Figures 1 to 7 As shown, the present invention provides a board-end connector, including an outer plastic shell 1, an inner plastic shell 2, a PIN pin 4 and a PCB board 3. The outer plastic shell 1 is provided with a plug-in through hole 11 along a first direction X, and the outer plastic shell 1 is used to assemble with the sheet metal 6; the inner plastic shell 2 is provided with an avoidance hole 211 along the first direction X, and the inner plastic shell 2 is detachably inserted into the plug-in through hole 11 and has a movable gap between it and the outer plastic shell 1; the PCB board 3 is located on the side of the outer plastic shell 1 facing away from the sheet metal 6, and the PCB board 3 is provided with a mounting hole 31; the PIN pin 4 is inserted into the avoidance hole 211 of the inner plastic shell 2, and both axial ends of the PIN pin 4 extend out of the inner plastic shell 2, and one axial end of the PIN pin 4 is inserted into the mounting hole 31 of the PCB board 3 and is welded to the PCB board 3.

[0044] When the PCB board 3 and the PIN needle 4 are welded and fixed, the inner plastic shell 2 remains fixed in relative position with the PCB board 3 under the limiting action of the PIN needle 4. The outer plastic shell 1 is sleeved on the outside of the inner plastic shell 2. When the outer plastic shell 1 and the sheet metal 6 are fixed, the inner plastic shell 2 and the outer plastic shell 1 are detachably connected and a movable gap is provided, which can compensate for the assembly tolerance and reduce the extrusion of the sheet metal 6.

[0045] Optionally, one of the inner plastic shell 2 and the outer plastic shell 1 is provided with a guide groove 212 along the first direction X, and the other is provided with a guide block, which can be inserted into the guide groove 212 and slide in the first direction X in the guide groove 212.

[0046] Exemplarily, the guide groove 212 is formed on the outer surface of the inner molded case 2. The longitudinal direction of the guide groove 212 is parallel to the first direction X, and the guide groove 212 extends through the bottom end surface of the inner molded case 2 at one end thereof to form an opening. A guide block is protruding from the inner wall surface of the outer molded case 1. When the inner molded case 2 and the outer molded case 1 are plugged together along the first direction X, the guide block can enter the guide groove 212 from the opening along the first direction X, thereby regulating the plugging trajectory of the inner molded case 2 and the outer molded case 1.

[0047] Optionally, one of the inner plastic shell 2 and the outer plastic shell 1 is provided with a slide groove 213 along the first direction X, and the other is provided with a slider 13. The slider 13 can undergo elastic deformation, and the slider 13 can be inserted into the slide groove 213 and slide in the slide groove 213.

[0048] Exemplarily, a slide groove 213 is provided in the inner molded case 2. The length of the slide groove 213 is parallel to the first direction X, and both ends of the slide groove 213 are closed. A slider 13 is protruding from the inner wall surface of the outer molded case 1. When the inner molded case 2 and the outer molded case 1 are plugged together along the first direction X, a guide block is pressed against one side wall of the slide groove 213, causing the guide block to elastically deform. After entering the slide groove 213, the guide block recovers its deformation. Thus, the connection between the guide block and the slide groove 213 allows relative sliding between the inner molded case 2 and the outer molded case 1 in the first direction X, while maintaining a constant connection. Since the inner molded case 2 and the outer molded case 1 can be adjusted in the first direction X, they can accommodate PCB boards 3 of varying thicknesses. Specifically, when the PCB board 3 is relatively thick, the PCB board 3 can press the inner molded case 2 toward the outer molded case 1, exposing the PIN pins 4 as much as possible outside the inner molded case 2 for soldering.

[0049] Optionally, a first sealing member is sandwiched between the inner plastic shell 2 and the outer plastic shell 1 .

[0050] Exemplarily, the first sealing member is a sealing ring, which is fixed to the inner wall of the outer plastic shell 1. When the inner plastic shell 2 and the outer plastic shell 1 are plugged in, the first sealing member is sleeved on the inner plastic shell 2, and the first sealing member is deformed under the extrusion of the inner plastic shell 2 and the outer plastic shell 1, filling the gap between the two and realizing the sealing between the inner plastic shell 2 and the outer plastic shell 1.

[0051] Optionally, the outer plastic shell 1 is provided with a protruding positioning column 14 , the axial direction of the positioning column 14 is parallel to the first direction X, the PCB board 3 is provided with a positioning hole 32 , and the positioning column 14 is inserted into the positioning hole 32 .

[0052] For example, the outer plastic shell 1 is provided with four positioning posts 14, and the four positioning posts 14 are distributed in a matrix. The PCB board 3 is provided with four positioning holes 32 accordingly. When the PCB board 3 is plugged into the assembly formed by the inner plastic shell 2 and the outer plastic shell 1, the four positioning posts 14 are plugged into the four positioning holes 32 one by one, and the PIN needle 4 is inserted into the mounting hole 31. The plug-in relationship between the positioning posts 14 and the positioning holes 32 can keep the position between the PCB board 3 and the inner plastic shell 2 and the outer plastic shell 1 relatively fixed, which is convenient for the later welding of the PIN needle 4 and the PCB board 3, and can also share the tangential force for the PIN needle 4 to avoid deformation of the PIN needle 4.

[0053] Optionally, the positioning column 14 is provided with a threaded hole 15 , the opening of the threaded hole 15 faces away from the PCB board 3 , the sheet metal 6 is connected to the outer plastic shell 1 through a threaded fastener, and the threaded fastener is inserted into the threaded hole 15 and threadedly connected to the outer plastic shell 1 .

[0054] For example, a first through-hole 61 is defined in the center of the sheet metal 6, and a second through-hole 62 is defined around the through-hole, corresponding one-to-one with the positioning post 14. After the outer plastic shell 1 is inserted into the first through-hole 61, the second through-hole 62 is coaxially arranged with the threaded hole 15 defined in the positioning post 14. A threaded fastener passes through the second through-hole 62 and is inserted into the threaded hole 15. The sheet metal 6 is then clamped between the nut of the threaded fastener and the outer plastic shell 1 to complete the assembly. Using threaded fasteners to connect the sheet metal 6 and the outer plastic shell 1 facilitates assembly. Providing threaded holes 15 in the positioning post 14 eliminates the need for a design to avoid the threaded fasteners in the PCB 3, and also reduces the size of the outer plastic shell 1.

[0055] Optionally, the inner plastic shell 2 includes an inner plastic body 21 and a limiting column 22, the avoidance hole 211 is opened in the inner plastic body 21, one axial end of the limiting column 22 is fixed to the inner plastic body 21, and the other axial end forms a limiting portion, and the PCB board 3 is opened with a limiting hole 33, the limiting column 22 can be inserted into the limiting hole 33, and the limiting portion can undergo elastic deformation to switch its first state and second state. When in the first state, the width dimension of the limiting portion is greater than the aperture of the limiting hole 33, and when in the second state, the width dimension of the limiting portion is less than or equal to the aperture of the limiting hole 33.

[0056] Exemplarily, the limiting column 22 includes a first column 221 and a second column 222, and the first column 221 and the second column 222 are spaced apart in a direction perpendicular to the axial direction of the limiting column 22. In the axial projection of the limiting column 22, the cross-sections of the first column 221 and the second column 222 are both semicircular, and the straight sides of the semicircles are adjacent. The first column 221 and the second column 222 can undergo elastic deformation, and the ends of the first column 221 and the second column 222 away from the inner plastic body 21 can approach or move away from each other. The end of the first column 221 away from the inner plastic body 21 is provided with a first limiting portion, and the end of the second column 222 away from the inner plastic body 21 is provided with a second limiting portion. When the limiting portion is not subjected to external force, it is in a first state, and the first The limiting portion and the second limiting portion are far away from each other, and the radial distance between the two is D1, satisfying D1>D, where D is the diameter of the limiting hole 33 of the PCB board 3. When the limiting column 22 is plugged into the limiting hole 33, the first limiting portion and the second limiting portion are squeezed and approach each other, causing the first column 221 and the second column 222 to undergo elastic deformation, and the limiting portion is in the second state. The radial distance between the first limiting portion and the second limiting portion is D2, satisfying D2≤D, so that after the limiting portion can pass through the limiting hole 33, the limiting component returns to the first state. In this way, the limiting column 22 cannot exit the limiting hole 33 along the original path, so that the PCB board 3 and the inner plastic shell 2 remain relatively fixed, so that the subsequent PCB board 3 and the PIN needle 4 can be welded and fixed.

[0057] Optionally, a second sealing member 52 is installed on the side of the outer plastic shell 1 facing away from the PCB board 3. The outer plastic shell 1 can be inserted into the sheet metal 6. The second sealing member 52 is clamped between the outer plastic shell 1 and the sheet metal 6 in the first direction X.

[0058] With this arrangement, when the outer plastic shell 1 and the sheet metal 6 are assembled along the first direction X, the second sealing member 52 is squeezed and deformed, and the second sealing member 52 can fill part of the gap between the outer plastic shell 1 and the sheet metal 6 to achieve sealing between the outer plastic shell 1 and the PCB board 3.

[0059] Optionally, the outer plastic shell 1 is provided with a placement groove 16 , and the second sealing member 52 is installed in the placement groove 16 .

[0060] Exemplarily, the outer plastic shell 1 is provided with an annular placement groove 16 on its circumferential edge, the threaded hole 15 is located on the inner side of the placement groove 16, the second seal 52 is a sealing ring, and the second seal 52 is partially inserted into the placement groove 16. When the outer plastic shell 1 and the sheet metal 6 are assembled along the first direction X, the second seal 52 undergoes elastic deformation.

[0061] An electronic device is also provided, comprising the above-mentioned board-end connector.
