[0025] The preferred embodiments of the present disclosure are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present disclosure may be combined with each other if no conflict occurs.
[0026] This embodiment provides an adaptive socket, which is used to be installed on a circuit board and has a self-adjusting function for the insertion deviation of the pins. Figures 1 to 4As shown, it includes a base 101 arranged on a circuit board, a correction block 102 arranged on the top of the base 101 and capable of sliding along the axial direction of the base 101, and at least one connecting pin 103. The connecting pin 103 includes a first contact portion 1031 arranged in the base 101, a second contact portion 1032 arranged in the correction block 102, and an elastic portion 1033 connecting the first contact portion 1031 and the second contact portion 1032, and the elastic portion 1033 has elastic deformation, so that the first contact portion 1031 and the second contact portion 1032 follow the relative sliding of the correction block 102 and the base 101 to generate relative displacement.
[0027] In this embodiment, the base 101 and the correction block 102 are both rectangular, and the base 101 is set on the circuit board. The correction block 102 can slide along the axial direction of the base 101 to produce relative displacement. The connecting needle 103 is set between the base 101 and the correction block 102. The first contact portion 1031 and the elastic portion 1033 of the connecting needle 103 are both plate-shaped. The overall strength of the plate-shaped first contact portion 1031 and the elastic portion 1033 is relatively high, which is conducive to the development of thinning electrical connectors. The second contact portion 1032 is set in a sheet shape. The second contact portion 1032 is used to contact the plug-in, and the sheet-shaped second contact portion 1032 increases the contact area with the plug-in, improves the reliability of the device, and reduces the risk of failure. During actual use, according to the position of the plug-in, the correction block 102 is pushed along the axial direction of the base 101. Since the elastic part 1033 has the property of elastic deformation, the sliding of the correction block 102 can drive the second contact part 1032 to produce relative displacement, so that it corresponds to the plug-in that needs to be assembled.
[0028] Through the above technical solution, by arranging an adaptive socket 100 on the circuit board, after the first contact portion 1031 of the connecting pin 103 is welded to the circuit board, by sliding the correction block 102 along the axial direction of the base 101 to adjust the position of the second contact portion 1032 of the connecting pin 103, the accuracy of the position of the connecting pin 103 during insertion can be effectively improved, and the dimensional tolerance of the connecting pin 103 welded to the circuit board can be guaranteed, thereby solving the problem of large position deviation when the PIN pin is welded to the circuit board, making it difficult to assemble the PIN pin, and reducing production costs and failure risks.
[0029] In some embodiments, at least one plug hole 1021 is provided on the top surface of the correction block 102 away from the base 101, a cavity is formed in the base 101, at least one via hole is provided at the bottom of the base 101, the elastic part 1033 is provided in the cavity, the first contact part 1031 passes through the via hole to be electrically connected to the circuit board, and the second contact part 1032 is inserted into the plug hole 1021 and fixed. The plug hole 1021 corresponds to the shape setting of the second contact part 1032, and the via hole corresponds to the shape setting of the first contact part 1031. Such matching structures have a better assembly effect and will not cause loose parts. At the same time, after the first contact part 1031 is fixed on the circuit board, the second contact part 1032 is adjusted by the correction block 102, so as to facilitate the precise control of the position of the connecting pin 103 and improve the stability of the overall performance of the product.
[0030] In some embodiments, the elastic portion 1033 includes a first straight portion 10331, a bent portion 10332, and a second straight portion 10333 connected in sequence, the first straight portion 10331 connects the first contact portion 1031, the second straight portion 10333 connects the second contact portion 1032, and the bent portion 10332 is an S-shaped structure arranged along the relative sliding direction of the vertical correction block 102 and the base 101. The first straight portion 10331 and the second straight portion 10333 are arranged at intervals, and the bent portion 10332 connects the first straight portion 10331 and the second straight portion 10333. The bent portion 10332 extends along the width direction of the base 101, so that the connecting needle 103 has sufficient elasticity and strength, so that when the connecting needle 103 is displaced and deformed, the risk of fatigue of the first contact portion 1031 or the second contact portion 1032 can be reduced, stress concentration can be avoided, and the connecting needle 103 is broken, thereby reducing production costs and maintenance costs.
[0031] In some embodiments, the first contact portion 1031 passes through the via hole and then bends to be parallel to the bottom surface of the base 101, and is soldered to the circuit board. The first contact portion 1031 passes through the via hole and then bends to be parallel to the bottom surface of the base 101, which can increase the area where the first contact portion 1031 is connected to the circuit board, and improve the reliability of the device and the stability of the connection.
[0032] In some embodiments, the bottom surface of the base 101 is provided with an avoidance groove 1011 along the relative sliding direction of the vertical correction block 102 and the base 101, and the first contact portion 1031 is at least partially placed in the avoidance groove 1011 after being bent. In this way, it is possible to avoid the first contact portion 1031 from directly interfering with the board surface of the circuit board after passing through the via hole and causing breakage, thereby reducing production costs and improving economic benefits.
[0033] In some embodiments, along the relative sliding direction of the correction block 102 and the base 101, one of the opposite sides of the base 101 and the correction block 102 is provided with two opposite slides 1012, and the other is provided with two opposite slide rails 1022. The slides 1012 and the slide rails 1022 match each other and can slide relative to each other. The mutual cooperation between the slides 1022 and the slides 1012 reduces the friction between the base 101 and the correction block 102, so that the correction block 102 can slide better on the base 101 through the slide rails 1022, and achieves precise control of the position of the connecting needle 103, reducing the risk of structural failure.
[0034] In some embodiments, two opposite sides of the base 101 perpendicular to the relative sliding direction of the correction block 102 and the base 101 are provided with ears 1013 facing the correction block 102, and the ears 1013 are provided with a slot 1014. A clamping protrusion 1023 is provided at a position corresponding to the ears 1013 on the side of the correction block 102. The ears 1013 are clamped and connected with the clamping protrusion 1023, thereby limiting the separation of the base 101 and the correction block 102. In this embodiment, the ears 1013 are arranged in a plate shape, and the inner side wall of the ears 1013 is in contact with the outer side wall of the correction block 102. A slot 1014 is provided on the ear 1013 along the relative sliding direction of the correction block 102 and the base 101. The ear 1013 is inserted into the slot 1014 to lock the base 101 and the correction block 102 with each other to avoid separation, thereby preventing the correction block 102 from being separated from the base 101 when adjusting the position of the connecting needle 103, thereby preventing structural failure and improving product reliability.
[0035] In some embodiments, along the relative sliding direction of the correction block 102 and the base 101, the length of the card slot 1014 is greater than the length of the card protrusion 1023, thereby limiting the relative sliding displacement of the correction block 102 and the base 101. This arrangement ensures that the correction block 102 will not deviate in other directions when adjusting the position of the connecting pin 103, and can only slide along the axial direction of the base 101 and will not separate from the base 101, further improving the reliability of the product.
[0036] In some embodiments, the number of the connecting pins 103 along the relative sliding direction perpendicular to the correction block 102 and the base 101 is greater than or equal to two, and a spacer plate 104 facing the correction block 102 is provided on the bottom surface of the cavity, and the spacer plate 104 extends along the relative sliding direction of the correction block 102 and the base 101 and separates the adjacent connecting pins 103. The spacer plate 104 separates the two adjacent connecting pins 103 from each other, thereby preventing the two adjacent connecting pins 103 from accidentally touching and connecting electricity when the connecting pins 103 follow the correction block 102 to move and deform, resulting in a short circuit or leakage, thereby improving the safety of the device.
[0037] In some embodiments, a snap-fit structure is provided between the outer wall of the second contact portion 1032 and the inner wall of the plug-in hole 1021. When the second contact portion 1032 is inserted into the plug-in hole 1021, the snap-fit structures snap-fit each other to prevent the second contact portion 1032 from being separated from the plug-in hole 1021. The provision of the snap-fit structure can prevent the second contact portion 1032 from being separated from the correction block 102, resulting in failure of the adjustment capability, and helps to improve the overall performance stability of the product. In this embodiment, a limiting groove can be provided in the plug-in hole 1021, and a limiting strip is provided on the side wall of the limiting groove corresponding to the second contact portion 1032. The limiting strip is inserted into the limiting groove to lock the second contact portion 1032 with the correction block 102. In other embodiments, other snap-fit structures may also be used, which are not limited here.
[0038] In some embodiments, along the relative sliding direction of the correction block 102 and the base 101, hooks 105 are respectively provided on the two sides opposite to the base 101, and openings are provided on the circuit board at positions corresponding to the hooks 105, and the hooks 105 pass through the openings to lock the base 101 with the circuit board. When the base 101 is mounted on the circuit board, the hooks 105 can be pre-positioned by passing through the openings, thereby ensuring that the connecting pins 103 can be accurately positioned at the designated position on the circuit board during the process of being soldered to the circuit board, thereby improving work efficiency.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present disclosure.
[0040] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present disclosure without departing from the spirit and scope of the embodiments of the present disclosure. Thus, if these modifications and variations of the embodiments of the present disclosure fall within the scope of the claims of the present disclosure and their equivalents, the present disclosure is also intended to include these modifications and variations.
