[0027] In the first aspect, the utility model provides a plug-in connector socket, which is used for plugging and connecting with a flat cable 30 with a plug terminal 31 at the end. The plug-in connector socket provided by the utility model includes a base 10 and an upper cover 20. The top of the base 10 forms an opening 18, and a circuit board 11 is provided at the opening 18 of the base 10. A wiring terminal 12 for plugging with the plug terminal 31 is installed on the top of the circuit board 11. Two concave platforms 13 are respectively provided on both sides of the top of the base 10 near the wiring terminal 12, both of which are concave downwards; the upper cover 20 is detachably covered with a cover 20. An insertion space 24 is formed at the opening 18 and enclosed with the base 10, and the terminal 12 is accommodated in the insertion space 24; two protrusions 21 are provided at the bottom of the upper cover 20, both of which protrude downward, and the two protrusions 21 are respectively matched with the two recesses 13, and a threading hole 23 connected to the insertion space 24 is formed at a position between the two protrusions 21 on the upper cover 20, and the threading hole 23 is for the cable 30 to pass through, and a limit block 211 is provided on one side of each protrusion 21 facing the threading hole 23, and the limit block 211 is used to limit the plug terminal 31 inserted on the terminal 12.
[0028] like Figure 1 and Figure 2As shown, the base 10 is supported below the circuit board 11, the circuit board 11 blocks the opening 18 at the top of the base 10, the wiring terminal 12 is installed on the top of the circuit board 11, and the upper cover 20 is detachably covered on the base 10 to accommodate the wiring terminal 12 in the plug-in space 24. When the wiring terminal 12 is plugged and connected with the plug terminal 31, the flat cable 30 passes through the plug-in space 24 through the threading hole 23. When the socket of the present technical solution is connected with the external flat cable 30, the upper cover 20 needs to be disassembled first, and after the wiring terminal 12 is plugged and connected with the plug terminal 31, the upper cover 20 is covered on the base 10, and the two protrusions 21 on the upper cover 20 are respectively matched with the two concave platforms 13 on the base 10, and the two limit blocks 211 abut and fix the plug terminal 31 in the plug-in space 24.
[0029] The socket of the plug-in connector proposed in the utility model, through the cooperation between the upper cover 20 and the base 10, enables the upper cover 20 to cover the circuit board 11 and the wiring terminal 12 in the plug-in space 24, isolates the circuit board 11 and the wiring terminal 12 from the external environment, and enables the upper cover 20 and the base 10 to jointly provide protection for the circuit board 11 and the wiring terminal 12. By opening a threading port 23 on the upper cover 20 and setting limit blocks 211 on both sides of the threading port 23, the flat cable 30 can pass through the threading port 23 smoothly, and the plug terminal 31 is limited in the plug-in space 24 under the action of the two limit blocks 211, so that the upper cover 20 fixes the plug terminal 31, which can effectively prevent the plug terminal 31 from falling off, and ensure that the plug terminal 31 is firmly connected to the wiring terminal 12, thereby improving the connection stability and reliability of the plug-in connector.
[0030] In one embodiment, each protrusion 21 protrudes toward the threading opening 23 to form a limit block 211 , and each limit block 211 abuts against the plug terminal 31 inserted on the connection terminal 12 toward one side of the insertion space 24 to limit the plug terminal 31 .
[0031] It should be noted that when the upper cover 20 is covered on the base 10, the wiring terminal 12 is located in the insertion space 24 formed by the upper cover 20 and the base 10, and the cable 30 passes through the threading port 23 formed by the upper cover 20 and the base 10. The two protrusions 21 on the upper cover 20 are respectively located at the left and right ends of the threading port 23. Each protrusion 21 is provided with a limit block 211 in the direction of the other protrusion 21. Each limit block 211 extends toward the threading port 23. The plug terminal 31 is plug-connected with the wiring terminal 12 and abuts against the side of the limit block 211 facing the insertion space 24. The plug terminal 31 is limited in the insertion space 24 by the limit block 211, which effectively prevents the plug terminal 31 from falling off the wiring terminal 12, thereby ensuring a firm connection between the plug terminal 31 and the wiring terminal 12.
[0032] In one embodiment, one side of the base 10 corresponding to the threading opening 23 protrudes away from the insertion space 24 to form a support platform 14 , and both sides of the top of the support platform 14 are recessed downward to form two concave platforms 13 .
[0033] like Figure 2 As shown, the connection terminal 12 is installed at the edge of the circuit board 11 and faces outward, and the support platform 14 is arranged on the outside of the connection terminal 12, and provides support for the plug terminal 31 when the plug terminal 31 is connected to the connection terminal 12 to prevent the plug terminal 31 from swinging. Two concave platforms 13 are respectively arranged on the left and right sides of the support platform 14. When the upper cover 20 is covered on the base 10, the upper cover 20 and the top surface of the support platform 14 enclose a threading port 23, so that the support platform 14 provides support for the cable 30 passing through the threading port 23.
[0034] In one embodiment, the outer edge of the base 10 corresponding to the opening 18 is recessed downward to form a lower step 19, which extends circumferentially along the edge of the opening 18 and is connected between the two recesses 13; the edge of the upper cover 20 forms an upper step 22 that cooperates with the lower step 19, and the upper step 22 is connected between the two protrusions 21.
[0035] It should be noted that the base 10 has an opening 18 formed in the middle, the base 10 has a lower step 19 formed at the edge, and the upper cover 20 has an upper step 22 formed at the edge to match the lower step 19, so that when the upper cover 20 is placed on the base 10, the upper step 22 and the lower step 19 are combined to achieve the positioning of the upper cover 20 and the base 10. Figure 2 As shown, the two recesses 13 are respectively located on the left and right sides of the supporting platform 14, and the lower step 19 is arranged along the edge of the base 10 and is respectively connected to the two recesses 13. Similarly, the upper step 22 is arranged along the edge of the upper cover 20 and is respectively connected to the two protrusions 21, so that the upper cover 20 can be accurately covered on the base 10.
[0036] In one embodiment, the base 10 is annular, and a screw mounting column 16 is provided on the inner wall of the base 10. The upper cover 20 is threadedly connected to the screw mounting column 16 through screws 15. The screw mounting column 16 is located below the circuit board 11, and an avoidance hole 111 for avoiding the screws 15 is opened on the circuit board 11.
[0037] It can be explained that the inner wall of the base 10 is arranged in a ring and encloses an opening 18, and a screw mounting column 16 is vertically arranged on the inner wall of the base 10. The circuit board 11 is covered above the screw mounting column 16, and an avoidance hole 111 is opened corresponding to the position of the screw mounting column 16. The upper cover 20 is provided with a screw hole for the screw 15 to pass through. The screw 15 passes through the screw hole of the upper cover 20 and then passes through the avoidance hole 111, and finally cooperates with the screw mounting column 16 on the inner wall of the base 10 to tightly connect the upper cover 20 to the upper part of the base 10. When the wiring terminal 12 is connected or disconnected with the plug terminal 31, the screw 15 must be removed from the screw mounting column 16 first, and the upper cover 20 must be removed from the base 10. The connection between the upper cover 20 and the base 10 is achieved by the threaded connection between the screw 15 and the screw mounting column 16. The connection is stable and easy to load and unload, which is conducive to repeated use.
[0038] In one embodiment, the number of the screw mounting posts 16 and the number of the screws 15 are both multiple, and the number of the multiple screws 15 is consistent with the number of the multiple screw mounting posts 16 and they are threadedly connected in a one-to-one correspondence.
[0039] Furthermore, a plurality of screw mounting posts 16 are circumferentially spaced apart along the inner wall of the base 10, and a plurality of screws 15 are respectively connected to the plurality of screw mounting posts 16 in a one-to-one correspondence, thereby ensuring that the connection force at each position of the upper cover 20 and the base 10 is evenly distributed, further improving the connection force between the upper cover 20 and the base 10, and thereby ensuring a stable connection between the wiring terminal 12 and the plug terminal 31.
[0040] In one embodiment, a positioning column 17 is disposed on the inner wall of the base 10 , a positioning hole 112 cooperating with the positioning column 17 is opened on the circuit board 11 , and the positioning column 17 and the screw mounting column 16 are spaced apart.
[0041] like Figure 2 As shown, the inner wall of the base 10 extends toward the opening 18, the circuit board 11 is placed on the inner wall of the base 10, the inner wall of the base 10 is provided with two positioning posts 17, and each positioning post 17 extends vertically along the top of the inner wall of the base 10, the circuit board 11 is provided with two positioning holes 112 corresponding to the positions of the two positioning posts 17, and the two positioning posts 17 pass through the two positioning holes 112 respectively to position and fix the circuit board 11 on the inner wall of the base 10. When the upper cover 20 is connected to the base 10 by a plurality of screws 15, the plurality of screws 15 pass through the avoidance holes 111 on the circuit board 11 respectively, and the plurality of screws 15 and the two positioning posts 17 jointly fix the circuit board 11 on the base 10, and jointly ensure the stable setting of the circuit board 11.
[0042] In one embodiment, a downwardly recessed receiving groove 25 is provided at a position of the upper cover 20 corresponding to the screw 15 , and the receiving groove 25 is used to receive the head of the screw 15 .
[0043] It can be understood that the screw rod of the screw 15 passes through the screw hole provided in the upper cover 20 and extends downward, and the head of the screw 15 abuts against the screw hole. The position where the screw 15 is provided in the upper cover 20 is recessed downward, so that the head of the screw 15 is located in the receiving groove 25, avoiding the head of the screw 15 from being directly exposed on the upper surface of the upper cover 20, preventing the screw 15 from colliding with other components, and making the upper surface of the upper cover 20 more neat and beautiful.
[0044] In one embodiment, the upper cover 20 and the base 10 are both integrally formed.
[0045] It should be noted that the protrusion 21, the limit block 211, the upper step 22 and the groove in the upper cover 20 are all integrally formed with the upper cover 20. Similarly, the recessed platform 13, the lower step 19 and other structures in the base 10 are all integrally formed with the lower cover, so that the upper cover 20 and the base 10 have higher structural strength and better consistency, and the connection between the upper cover 20 and the base 10 is more stable.
[0046] In a second aspect, the utility model provides a plug-in connector, comprising a flat cable 30 and the above-mentioned socket, wherein the end of the flat cable 30 is provided with a plug terminal 31 plugged with the connection terminal 12 .
[0047] like Figure 3 As shown, the plug terminal 31 at the end of the flat cable 30 extends into the plug-in space 24 of the socket and plugs and connects with the wiring terminal 12 to achieve the connection of the plug-in connector. The flat cable 30 passes through the threading port 23 and is connected to the external device. The upper cover 20 is covered on the base 10 and is tightly connected to the base 10 to cover the plug terminal 31 and the wiring terminal 12 in the plug-in space 24 to provide protection for the plug terminal 31 and the wiring terminal 12, and limit the plug terminal 31 in the plug-in space 24, thereby preventing the plug terminal 31 from falling off, and improving the connection stability of the plug-in connector.
[0048] The utility model also provides a plug-in connector, which includes the above-mentioned socket. The specific structure of the socket refers to the above-mentioned embodiment.
