[0037] Embodiment 1 of the connector and circuit board structure of the utility model

[0038] Please refer to Figure 1-Figure 2 The connector and circuit board structure of the utility model includes: a circuit board body 1 and a connector body 2 arranged on the circuit board body 1, two window bodies 101 are arranged on the circuit board body 1, and a pad body 102 is arranged between the circuit board body 1 and the two window bodies 101. The size of the pad body 102 is larger than the size of the window body 101. In this application, the size of the pad body 102 is larger than the size of the window body 101, so that in addition to the part exposed by the window body 101, a part of the pad body 102 can be encapsulated in the circuit board body 1, so that the circuit board body 1 can fix the pad body 102, making the pad body 102 more secure, and can reduce the detachment of the pad body 102 during the plugging and unplugging of the connector body 2, thereby improving the problem of the pad falling off.

[0039] Further, such as Figure 1-Figure 2As shown, both sides of the connector body 2 have connector fixing feet 201, and the two connector fixing feet 201 are welded together with the two pad bodies 102 respectively. The main function of welding the pad bodies 102 and the connector fixing feet 201 together is to ensure a firm connection between the connector body 2 and the circuit board body 1. Through welding, the pins of the connector body 2 and the circuit board body 1 are firmly fixed together to form a reliable electrical connection. During the welding process, the solder will melt and wet between the connector fixing feet 201 and the pad bodies 102, and then solidify through cooling, so that the two are tightly combined. This connection not only has good conductive properties, but also provides sufficient mechanical strength to ensure the stability and reliability of the connector body 2 on the circuit board body 1. The welding of the connector fixing feet 201 and the pad bodies 102 plays a vital role in the manufacture of electronic equipment, which ensures the stability and reliability of the equipment performance.

[0040] Embodiment 2 of the connector and circuit board structure of the utility model

[0041] Please refer to Figure 1-Figure 2 The connector and circuit board structure of the utility model includes: a circuit board body 1 and a connector body 2 arranged on the circuit board body 1, two window bodies 101 are arranged on the circuit board body 1, and a pad body 102 is arranged between the circuit board body 1 and the two window bodies 101. The size of the pad body 102 is larger than the size of the window body 101. In this application, the size of the pad body 102 is larger than the size of the window body 101, so that in addition to the part exposed by the window body 101, a part of the pad body 102 can be encapsulated in the circuit board body 1, so that the circuit board body 1 can fix the pad body 102, making the pad body 102 more secure, and can reduce the detachment of the pad body 102 during the plugging and unplugging of the connector body 2, thereby improving the problem of the pad falling off.

[0042] Further, such as Figure 1-Figure 2As shown, both sides of the connector body 2 have connector fixing feet 201, and the two connector fixing feet 201 are welded together with the two pad bodies 102 respectively. The main function of welding the pad bodies 102 and the connector fixing feet 201 together is to ensure a firm connection between the connector body 2 and the circuit board body 1. Through welding, the pins of the connector body 2 and the circuit board body 1 are firmly fixed together to form a reliable electrical connection. During the welding process, the solder will melt and wet between the connector fixing feet 201 and the pad bodies 102, and then solidify through cooling, so that the two are tightly combined. This connection not only has good conductive properties, but also provides sufficient mechanical strength to ensure the stability and reliability of the connector body 2 on the circuit board body 1. The welding of the connector fixing feet 201 and the pad bodies 102 plays a vital role in the manufacture of electronic equipment, which ensures the stability and reliability of the equipment performance.

[0043] Further, such as Figure 3-Figure 5 As shown, a first limiting member is provided on each of the two connector fixing feet 201, and two auxiliary positioning mechanisms 4 are provided on the circuit board main body 1; the auxiliary positioning mechanism 4 is used for auxiliary positioning of the connector main body 2 during welding, and the auxiliary positioning mechanism 4 is also used to cooperate with the first limiting member to realize auxiliary fixation of the connector fixing feet 201 after welding, so that the alignment of the connector main body 2 is more convenient during the welding process, and after the welding is completed, the limiting fixation of the connector fixing feet 201 by the auxiliary positioning mechanism 4 and the first limiting member can improve the stability of the connection between the connector fixing feet 201 and the pad main body 102.

[0044] Further, such as Figure 4 As shown, the first limiting member is a positioning slot 3 , which is provided on the connector fixing foot 201 , and is used to cooperate with the auxiliary positioning mechanism 4 to fix the connector fixing foot 201 .

[0045] Furthermore, the auxiliary positioning mechanism 4 includes a first positioning piece arranged on the circuit board body 1, and a second positioning piece is provided on the first positioning piece. The first positioning piece and the second positioning piece are used together for positioning the connector body 2 during welding, and the second positioning piece can be used in conjunction with the positioning slot 3 to limit the connector fixing foot 201 after welding.

[0046] Further, such as Figure 4-Figure 5 As shown, the first positioning member includes a connecting shaft 401 fixedly mounted on the top of the circuit board body 1, a positioning plate 402 is sleeved on the outer surface of the connecting shaft 401, and the second positioning member is arranged on the positioning plate 402. The connecting shaft 401 is used to connect the circuit board body 1 with the positioning plate 402, and the positioning plate 402 can rotate around the connecting shaft 401.

[0047] Further, such as Figure 5As shown, the second positioning member includes a positioning rod 403 inserted and connected to the positioning plate 402, and the bottom end of the positioning rod 403 contacts the top of the circuit board body 1. The friction between the positioning rod 403 and the circuit board body 1 can assist in positioning the positioning plate 402. After welding is completed, the positioning rod 403 can be plugged into the positioning slot 3. If necessary, a hole can be opened on the top of the circuit board body 1 for the positioning rod 403 to be inserted to fix the positioning plate 402.

[0048] Further, such as Figure 5 As shown, a cavity 404 is opened in the positioning plate 402, and the positioning rod 403 passes through the cavity 404. The outer surface of the positioning rod 403 is fixedly sleeved with a limiting baffle 405 located in the cavity 404, and the limiting baffle 405 can limit the positioning rod 403.

[0049] Further, such as Figure 5 As shown, the outer surface of the positioning rod 403 is sleeved with a spring located in the cavity 404, and the two ends of the spring are respectively fixedly connected to the cavity 404 and the limit baffle 405. The action force of the spring can limit the positioning rod 403 through the limit baffle 405, which can improve the stability of the positioning rod 403 when it is plugged into the positioning slot 3, and can also improve the friction between the positioning rod 403 and the circuit board body 1.

[0050] When in use, before welding, align the connector fixing foot 201 with the pad body 102, and contact the connector body 2 with the positioning plate 402, and use the positioning plate 402 to assist in positioning and limiting the connector body 2. The positioning of the connector body 2 by the positioning plate 402 can facilitate the connection between the connector fixing foot 201 and the pad body 102, and reduce the movement of the connector body 2 during welding. When the connector fixing foot 201 and the pad body 102 are welded together, pull the positioning rod 403 upwards and then rotate the positioning plate 402 around the connecting shaft 401 so that the positioning plate 402 contacts the top of the connector fixing foot 201, loosen the positioning rod 403 so that the positioning rod 403 is plugged into the positioning slot 3, that is, Figure 6 and Figure 7 As shown, at this time, the positioning plate 402 can press and fix the connector fixing foot 201, thereby reducing the possibility that the connection between the connector body 2 and the pad body 102 becomes loose due to external force during the plugging and unplugging process.
