[0002] A wire-to-board connector is an electronic component used to connect wires to a circuit board. Its main function is to enable the transmission of electrical signals and power to ensure the normal operation of the equipment. This type of connector is usually composed of a plastic shell and metal contacts. It is precisely designed to provide a reliable connection under various environmental conditions.

[0003] Through technological improvements, the soldering part of the second terminal of the double-row recessed wire-to-board connector has been moved upward, allowing the connector itself to be recessed to the middle of the side of the PCB board. This not only saves PCB board area but also improves space utilization.

[0004] Existing double-row recessed wire-to-board connectors are prone to dust accumulation on their surface during use. Dust buildup can lead to poor contact or increased resistance in the wire-to-board connectors, affecting current transmission. In addition, the snap-fit ​​double-row recessed wire-to-board connectors are not stable enough, and the contact points are prone to loosening or wear in vibration environments, thereby reducing signal transmission quality. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art where double-row recessed wire-to-board connectors are not easy to prevent dust, and the snap-fit ​​plug and socket are not stable enough. Under vibration, the contact points are prone to loosening or wear, which reduces the signal transmission quality. Therefore, a double-row recessed wire-to-board connector is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A double-row recessed wire-to-board connector includes a socket with a plug inserted at the connection end, a mounting bracket detachably mounted on the socket, and further includes: a folded fabric fixedly mounted on the mounting bracket, wherein the mounting bracket is provided with a driving part for moving the folded fabric, the moving direction of the folded fabric being the same as the insertion direction of the socket and the plug; and a fastening bolt threadedly connected within the mounting bracket, wherein the mounting bracket is provided with a linkage part for moving the fastening bolt, the moving direction of the fastening bolt being perpendicular to the moving direction of the folded fabric.

[0008] To facilitate dust protection of the socket and plug by driving the unfolding of the folded fabric, preferably, the driving unit includes a positioning shell fixedly connected to the mounting bracket. A threaded sleeve is fixedly connected inside the positioning shell, and an adjusting bolt is threadedly connected inside the threaded sleeve. The head of the adjusting bolt extends through the outside of the positioning shell. A first bevel gear is rotatably connected inside the positioning shell and is sleeved on the adjusting bolt. A second bevel gear is meshed with the first bevel gear. A lead screw is fixedly connected to the side of the second bevel gear away from the first bevel gear. The free end of the lead screw extends through the outside of the positioning shell. A limit plate is threadedly connected to the surface of the lead screw. A positioning frame is fixedly connected to the side of the limit plate away from the lead screw. The side of the folded fabric away from the mounting bracket is fixedly connected to the positioning frame.

[0009] To further limit the movement of the first bevel gear, a guide groove is provided on the adjusting bolt, and a forming groove that cooperates with the guide groove is provided inside the first bevel gear.

[0010] To limit the positioning frame and improve its lateral movement stability, a slider is fixedly connected to the bottom of the positioning frame, and a groove is provided on the mounting bracket to cooperate with the slider.

[0011] In order to secure and limit the elastic locking block on the plug, preferably, the linkage part includes a positioning rod, which is fixedly installed on the mounting bracket. A spherical gear is rotatably connected inside the positioning rod. A threaded groove is opened inside the spherical gear. The threaded end of the fastening bolt is threadedly connected to the threaded groove. A rack is meshed on the spherical gear. The side of the rack away from the spherical gear is fixedly connected to the positioning frame.

[0012] To further limit the lateral movement of the rack, a limiting block is fixedly connected to the rack, and a limiting groove that cooperates with the limiting block is provided in the mounting frame.

[0013] Compared with the prior art, this utility model provides a double-row recessed wire-to-board connector, which has the following advantages:

[0014] 1. This double-row recessed plate type wire-to-board connector, through the cooperation of slider and groove, can limit the lateral movement of the positioning frame and prevent the positioning frame from shifting during movement;

[0015] 2. This double-row recessed plate type wire-to-plate connector, through the cooperation of guide groove and forming groove, can limit the first bevel gear, so that the first bevel gear only follows the rotation of the adjusting bolt and does not move vertically downward, thereby increasing the stability of the first bevel gear in use.

[0016] The parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model sets up a folded cloth. When the driving part drives the folded cloth to move along the socket and plug insertion direction, the folded cloth opens, which can protect the socket and plug from dust. At the same time, the folded cloth drives the linkage part to move during the movement. When the linkage part moves, it drives the fastening bolt to move to one side of the plug, so that the fastening bolt abuts against the locking block on the surface of the plug, thereby improving the stability of the socket and plug connection.

[0027] Example:

[0028] Reference Figures 1-7 A double-row recessed plate type wire-to-board connector includes a socket 1, a plug 2 inserted into the socket 1, and a mounting bracket 6 detachably mounted on the socket 1. It also includes two folded fabrics 4 fixedly mounted on the mounting bracket 6, wherein the mounting bracket 6 is provided with a driving part 3 for driving the folded fabrics 4 to move, the moving direction of the folded fabrics 4 being the same as the insertion direction of the socket 1 and the plug 2; and two fastening bolts 8 threadedly connected within the mounting bracket 6, wherein the mounting bracket 6 is provided with a linkage part 5 for driving the fastening bolts 8 to move, the moving direction of the fastening bolts 8 being perpendicular to the moving direction of the folded fabrics 4.

[0029] Specifically, by setting up a folded cloth 4, when the driving unit 3 drives the folded cloth 4 to move along the insertion direction of the socket 1 and the plug 2, the folded cloth 4 opens, which can protect the socket 1 and the plug 2 from dust. At the same time, the folded cloth 4 drives the linkage unit 5 to move during the movement. When the linkage unit 5 moves, it drives the fastening bolt 8 to move to one side of the plug 2, so that the fastening bolt 8 abuts against the locking block on the surface of the plug 2, thereby improving the stability of the connection between the socket 1 and the plug 2.

[0030] The drive unit 3 includes a positioning shell 301 fixedly connected to the mounting bracket 6. A threaded sleeve 302 is fixedly connected inside the positioning shell 301, and an adjusting bolt 303 is threadedly connected inside the threaded sleeve 302. The head of the adjusting bolt 303 extends through the positioning shell 301. A first bevel gear 304 is rotatably connected inside the positioning shell 301. The first bevel gear 304 is sleeved on the adjusting bolt 303. Two second bevel gears 305 are meshed on the first bevel gear 304. A lead screw 306 is fixedly connected to the side of the second bevel gear 305 away from the first bevel gear 304. The surfaces of the two lead screws 306 are... The threads are opposite in shape. The free end of the lead screw 306 extends through the positioning shell 301. The surface of the lead screw 306 is threadedly connected to the limiting plate 307. The side of the limiting plate 307 away from the lead screw 306 is fixedly connected to the positioning frame 7. The side of the folded cloth 4 away from the mounting frame 6 is fixedly connected to the positioning frame 7. The adjusting bolt 303 has a guide groove. The first bevel gear 304 has a forming groove. The guide groove and the forming groove cooperate with each other. The bottom of the positioning frame 7 is fixedly connected to the slider 9. The mounting frame 6 has a sliding groove 10 that cooperates with the slider 9. The slider 9 slides inside the cavity of the sliding groove 10.

[0031] Specifically, by setting up the drive unit 3, the adjustment bolt 303 is rotated using a tool, causing the adjustment bolt 303 to drive the first bevel gear 304 and two second bevel gears 305 to rotate, thereby adjusting the position of the positioning frame 7 and the folded cloth 4, allowing the folded cloth 4 to unfold. Adjusting the folded cloth 4 using the adjustment bolt 303 can improve its stability in use. The guide groove and the forming groove cooperate to limit the first bevel gear 304, and the slider 9 and the slide groove 10 cooperate to limit the lateral movement of the positioning frame 7.

[0032] The linkage part 5 includes a positioning rod 501, which is fixedly installed on the mounting bracket 6. A spur gear 502 is rotatably connected inside the positioning rod 501. A threaded groove is opened inside the cavity of the spur gear 502. The threaded end of the fastening bolt 8 is threadedly connected to the threaded groove. A rack 503 is meshed on the spur gear 502. The side of the rack 503 away from the spur gear 502 is fixedly connected to the positioning frame 7. A limit block is fixedly connected to the top of the rack 503. A limit groove is opened inside the mounting bracket 6 to cooperate with the limit block. The limit block slides inside the cavity of the limit groove.

[0033] Specifically, by setting the linkage part 5, when the positioning frame 7 moves one end of the folded cloth 4, the rack 503 moves with the positioning frame 7 and drives the sprocket 502 to rotate, so that the fastening bolt 8 moves inside the sprocket 502. By adjusting the position of the fastening bolt 8, the locking block of the plug 2 can be limited, thereby improving the stability of the connection between the plug 2 and the socket 1. Furthermore, by using the limiting groove and the limiting block in cooperation, the rack 503 can be limited laterally.

[0034] Working principle: During use, the operator inserts plug 2 into socket 1. Because plug 2 has an elastic locking block, it engages fully after insertion into the socket 1. Then, the operator uses an external tool to rotate adjusting bolt 303. As adjusting bolt 303 rotates within threaded sleeve 302, it drives the first bevel gear 304 to rotate. The first bevel gear 304, in turn, drives two second bevel gears 305 to rotate. The two second bevel gears 305, in turn, drive two lead screws 306 to rotate. When rotating, the two positioning frames 7 move, and the positioning frames 7 move one end of the folded cloth 4, which unfolds the folded cloth 4. By adjusting the length of the folded cloth 4, the socket 1 and plug 2 can be protected from dust. At the same time, when the positioning frames 7 move, the rack 503 moves, and the rack 503 moves, which drives the spur gear 502 to rotate. When the spur gear 502 rotates, it drives the fastening bolt 8 with its internal thread to move. After the fastening bolt 8 moves and contacts the elastic block, it can be tightened, thereby improving the stability of the connection between the socket 1 and the plug 2.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
