[0040] After adopting the above technical scheme, the board-end connector socket 100 of the utility model can maintain sufficient contact surface and positive force during the process of plugging and unplugging with the plug, so as to meet the use of some occasions that require frequent plugging and unplugging or frequent vibration. The board-end connector socket 100 includes a shell assembly 10 and a contact assembly 20 arranged in the shell assembly 10, and the shell assembly 10 includes an upper cover 11, a base 12 and a base 13. One or more bases 12 are installed between the upper cover 11 and the base 13, and a receiving cavity 101 is formed in the upper cover 11, the base 12 and the base 13. The contact assembly 20 is installed in the receiving cavity 101. The contact assembly 20 includes at least one elastic contact member 201, each elastic contact member 201 is respectively installed at different positions in the receiving cavity 101, and multiple elastic contacts 201 are installed one by one. Among them, the elastic contact piece 201 includes an elastic contact structure 21 and a plug 22. The elastic contact structure 21 includes a plurality of springs 212. The plurality of springs 212 are distributed along the circumference to form a plug-in cavity 202 for inserting a plug, and the plurality of springs 212 can elastically press against the plug. This can maintain a sufficient contact surface and positive force during the plug-in and pull-out process. On the other hand, one end of the plug 22 is connected to the spring 212 structure, and the other end of the plug 22 passes through the housing assembly 10 and extends out of the housing assembly 10 to connect to the circuit board. The board-end connector socket 100 of the utility model has a reasonable structural design, can maintain a sufficient contact surface and positive force during the plug-in and pull-out process, and can better meet the occasions that require frequent plug-ins or frequent vibrations.

[0041] See also Figures 3 to 6 In some optional embodiments, the elastic contact structure 21 includes a fixing portion 211, the fixing portion 211 is annular, and a plurality of springs 212 are distributed on the fixing portion 211 along the circumferential direction. The size and number of the springs 212 can be set according to actual use needs, and each spring 212 can elastically move on the fixing portion 211 within a preset range. The preset range is the range in which the spring 212 elastically moves along the fixing portion 211 and can return to the initial state, that is, the spring 212 cannot be excessively deformed and cannot be restored.

[0042] See also Figure 3 , Figure 4 and Figure 7 In some optional embodiments, the base 12 and the base 13 are provided with a mounting portion 121 that cooperates with the fixing portion 211, and the mounting portion 121 is used to support the fixing portion 211 on which the elastic contact piece 201 is placed. Specifically, the corresponding elastic contact piece 201 is placed on the mounting portion 121 of the corresponding base 12 / base 13 through its fixing portion 211, so that the elastic contact piece 201 is installed on the base 12 or on the base 13. Among them, the elastic contact piece 201 located on the base 12, its insert piece 22 passes through one or more bases 12 and passes through the base 13 to extend outside the housing assembly 10. The elastic contact piece 201 located on the base 13, its insert piece 22 passes through the base 13 and extends outside the housing assembly 10. A hollow inner cavity 120 is opened in each base 12 to accommodate the elastic contact piece 201 and form an accommodating cavity 101.

[0043] See also Figures 2 to 7 In some optional embodiments, a positioning groove 123 is provided on the base 12 and the base 13, and a positioning portion 2122 is provided at one end of the spring 212, and one end of the positioning portion 2122 extends into the positioning groove 123 to strengthen the installation between the elastic contact member 201 and the base 12 or the base 13. For example, Figure 3 and Figure 4As shown, a hook-shaped protrusion 129 protrudes from one end of the base 12 / base 13, and the protrusion 129 protrudes toward the direction of the accommodating cavity 101 and forms a positioning groove 123 with the side wall 128 of the base 12 / base 13. Since the side wall 128 and the protrusion 129 are an integral structure, the bottom of the positioning groove 123 is closed. Among them, the positioning portion 2122 is vertical, so that it can be directly extended into the positioning groove 123 and abut against the inner wall of the positioning groove 123, and the fit is more secure and stable. On the other hand, each base 12 is provided with a curved surface structure 124 at one end where the positioning groove 123 is opened, and the curved surface structure 124 is used to facilitate the plugging and unplugging of the plug in the accommodating cavity 101. It can be understood that the curved surface structure 124 is formed on the outer surface of the protrusion 129, and the curved surface structure 124 can facilitate the insertion of the plug in the accommodating cavity 101. At the same time, when the plug is pulled out, the arc surface structure 124 has a guiding function, making it easier to pull out the plug in the accommodating cavity 101 .

[0044] See also Figure 3 and Figure 4In some optional embodiments, a support ring 50 is further provided between the housing assembly 10 and the contact assembly 20, and the support ring 50 is provided on the base 12 or the base 13 to support the elastic contact member 201. Among them, a support portion 122 for supporting the support ring 50 is provided on both the base 12 and the base 13. A hanging portion 51 cooperating with the support portion 122 is provided on the support ring 50, and the support ring 50 is installed on the support portion 122 by the hanging portion 51. In this embodiment, the support portion 122 and the hanging portion 51 are both L-shaped, so as to be hung with each other and the connection is stable. On the other hand, a contact portion 2121 protruding toward the plug-in cavity 202 is provided on the spring leaf 212, and the support ring 50 supports the contact portion 2121 so that the contact portion 2121 remains in a protruding state in the plug-in cavity 202. The support ring 50 is an annular structure, and an arc-shaped protrusion 52 matching the contact portion 2121 is provided on the support ring 50, and the contact portion 2121 is fitted on the arc-shaped protrusion 52, so that when the plug is inserted, the contact portion 2121 can maintain a protruding state, so that it can better contact with the plug and maintain conduction. The support ring 50 can be a plastic ring with a certain elasticity, so that when the plug is inserted, there is a certain elastic range of activity to ensure the smooth insertion of the plug, and the elastic force can be applied to the contact portion 2121 so that the contact portion 2121 remains in contact with the plug. At the same time, when the plug is pulled out, the elastic force of the spring 212 itself and the elastic force of the support ring 50 can make the contact portion 2121 squeezed by the plug elastically return to the initial state. Ensure that the plug can maintain sufficient contact surface and positive force during the plug-in and pull-out process. The material of the spring 212 is beryllium copper with high elasticity and fatigue resistance, and has a long service life, so that it can better meet the use of some occasions on the market that often require plug-in or vibration. Specifically, one end of the spring 212 is connected to the fixing portion 211, and gradually protrudes toward the plug cavity 202, and then gradually forms a contact portion 2121 that contacts the plug, and the contact portion 2121 is straight. The protruding and straight contact portion 2121 can increase the contact area with the plug, thereby better ensuring the conduction between the plug and the elastic contact member 201. The other end of the contact portion gradually shrinks inward and forms a straight positioning portion 2122.

[0045] See also Figure 7 and Figure 8In some optional embodiments, guide holes 125 for the insert 22 to pass through are provided on the base 12 and the base 13 at preset intervals. The intervals of the guide holes 125 can be set according to the number and structure of the elastic contact members 201 in actual needs. The preset interval is the distance between the inserts 22 on two upper and lower adjacent elastic contact members 201. Specifically, the guide holes 125 pass through the base 12 and the base 13, and each guide hole 125 is provided with a corresponding mark 126, so that the corresponding insert 22 can pass through the corresponding guide hole 125. The mark 126 can be a number, a letter, or other symbols that are easy to identify. It can be understood that from top to bottom, the length of the insert 22 gradually shortens so that the length of the insert 22 protruding from the housing assembly 10 remains constant, so as to facilitate installation. Therefore, when installing the elastic contact member 201, it is necessary to match the insert 22 with the corresponding mark 126 to avoid the inconsistent length of the insert 22 outside the housing assembly 10 and affecting the installation. In other embodiments, guide holes 125 for the inserts 22 to pass through are provided on both the base 12 and the base 13. The number of guide holes 125 on each base 12 increases one by one from the upper cover 11 to the base 13. It is understandable that the number of guide holes 125 provided on each base 12 can be the same, and then the installation position can be distinguished by the mark 126. The number of guide holes 125 on each base 12 can also be different. The guide holes 125 are provided according to the number of inserts 22 that actually need to pass through the base 12. The higher the installation position of the base 12 is, the fewer the inserts 22 pass through, and the fewer the guide holes 125 that need to be provided. However, this requires the identification of the installation order of the base 12.

[0046] See also Figure 7 and Figure 8 In some optional embodiments, the base 12 and the base 13 are further provided with positioning notches 127, and the housing assembly 10 is assembled in a preset manner by means of the positioning notches 127. It can be understood that positioning notches 127 are provided on the outer surface of each base 12 and the outer surface of the base 13, and the base 12 and the base 13 are installed by aligning the positioning notches 127, which makes the installation faster and more convenient.

[0047] See also Figure 3 and Figure 4In some optional embodiments, a pressing plate 30 is further provided in the accommodating chamber 101, and the pressing plate 30 is used to position the elastic contact member 201 between the upper cover 11 and the base 12, and a first slot 111 for accommodating the pressing plate 30 is provided in the upper cover 11. It can be understood that a pressing plate 30 is provided between the upper cover 11 and the uppermost base 12, and the pressing plate 30 is installed in the first slot 111 of the upper cover 11, so as to position the uppermost elastic contact member 201, thereby making the installation of the elastic contact member 201 more stable. When disassembling, it can also be disassembled more conveniently, so as to adjust the number of elastic contacts 201 and base 12 according to the actual needs of customers. On the other hand, a sealing member 40 is also provided in the accommodating chamber 101, and the sealing member 40 is used to make the plug sealed and plugged into the accommodating chamber 101. The upper cover 11 is provided with a second groove 112 for accommodating the sealing member 40. The sealing member 40 is installed in the second groove 112 and abuts against the pressing plate 30. Since the sealing member 40 is a plastic member with a certain elasticity, one side of the sealing member 40 abuts against the inner wall of the second groove 112 of the upper cover 11, and the other side abuts against the pressing plate 30. The sealing member 40 exerts a certain extrusion force on the pressing plate 30, so that the pressing plate 30 can be better pressed against the elastic contact member 201.

[0048] See also Figures 2 to 4 and Figure 7 and Figure 8 , a snap-fit ​​structure 14 is provided between the upper cover 11 and the base 12, between two adjacent bases 12, and between the base 12 and the base 13. Among them, the snap-fit ​​structure 14 includes a snap-fit ​​protrusion 141 and a snap-fit ​​hole 142 that cooperate with each other, and the snap-fit ​​protrusion 141 is snap-fitted into the snap-fit ​​hole 142 so that the upper cover 11, the base 12 and the base 13 are detachably connected to form a housing assembly 10. Of course, the upper cover 11, the base 12 and the base 13 can also be connected by other means such as snaps or threads. Specifically, if the snap-fit ​​hole 142 is provided on the upper cover 11, the upper cover 11 is snap-fitted and connected with the snap-fit ​​protrusion 141 on its adjacent base 12. If the snap-fit ​​protrusion 141 is provided on the upper cover 11, the upper cover 11 is snap-fitted and connected with the snap-fit ​​hole 142 on its adjacent base 12. The base 12 is provided with a snap-fit ​​protrusion 141 on one side and a snap-fit ​​hole 142 on the other side.
