[0002] Wire-to-board connectors are specific connectors used to connect wires or cables to circuit boards. They are designed to provide fast, reliable and repeatable connections to meet the needs of different applications. They usually refer to devices used to connect cables or wires to circuit boards (PCBs). This process is also called wire-to-board connection.

[0003] After searching, Chinese patent number announcement number CN214044236U discloses a wire-to-board connector, including an insulating rubber block, a plug pin and a wiring harness, the outer wall surface of the insulating rubber block is provided with a notch, and the inside of the notch is provided with a pinhole, the plug pin is fixed inside the pinhole, the top of the insulating rubber block is connected to a rubber shell needle seat, the rubber shell needle seat and the insulating rubber block are snap-fitted, the wiring harness is fixed inside the harness hole, and the outer wall surfaces of the left and right ends of the insulating rubber block are provided with grooves. The utility model sets the size between the pinhole and the plug pin so that the plug pin can fully contact the pinhole, thereby improving the degree of fit between them, and then the pinhole can position the plug pin, thereby reducing the low degree of fit between them, resulting in the plug pin being separated from the inside of the pinhole when the wiring harness and the plug pin are combined, thereby affecting the accuracy of the connection between the above two, and then affecting the normal use of the wire-to-board connector.

[0004] Many wire-to-board connectors on the market have great limitations (volume, material, and use environment). The PCB board has a greater impact and the opening of the connector cannot be fixed. As a result, when the connector is affected by external forces, the stability of its internal parts is affected. In response to this technical problem, this application proposes a small-volume wire-to-board connector. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A small-volume wire-to-board connector comprises a base plate, the top of the base plate is slidably connected to a socket, the top of the socket is fixedly connected to a shell, the socket is connected to a first semi-circular arc plate through a limiting component, a plurality of clamping holes are evenly opened in the middle of the inner walls on both sides of the socket from top to bottom, the inside of the clamping holes on both sides are clamped with a second semi-circular arc plate, grooves are opened on both sides of the top of the socket, and top covers are clamped inside the grooves on both sides.

[0008] Furthermore, the limiting assembly includes springs fixedly connected at two sides of the bottom of the top cover, and one end of the springs at both sides away from the top cover is fixedly connected to a first semi-circular arc plate.

[0009] Furthermore, a plurality of convex balls are fixedly connected to the inner walls of the first semi-circular arc plate and the second semi-circular arc plate.

[0010] Furthermore, lifting rings are fixedly connected to the middle parts of the front and rear sides of the second semicircular arc plate.

[0012] Furthermore, both sides of the top of the bottom plate are fixedly connected with convex rails, and the inner wall of the receiving seat is slidably connected to the top of the convex rails on both sides.

[0013] Furthermore, telescopic rods are fixedly connected to the front and rear sides of the top of the bottom plate between the convex rails on both sides, and the top ends of the telescopic rods on both sides are fixedly connected to receiving plates.

[0014] The utility model has the following beneficial effects:

[0015] In the utility model, the connection wire harness can be limited and fixed by the arrangement of the spring, the first semi-circular plate, the second semi-circular plate, the convex ball, the lifting ring and the clamping hole to avoid position displacement, ensure the fitting and docking between the wire harness and the plug pin, and thus ensure the stability of the wire-to-board connection.

[0026] Specifically, according to the size specifications of the wiring harness, the second semi-circular plate 9 is first clamped to the inner wall of the corresponding clamping hole 13, and then the top cover 6 is clamped to the top of the outer shell 4 through the grooves 5 on both sides, so that the inner wall of the first semi-circular plate 8 can abut against the top outer wall of the wiring harness.

[0027] Further explanation, springs 7 are fixedly connected to both sides of the bottom of the top cover 6, and one end of the springs 7 on both sides away from the top cover 6 is fixedly connected to a first semi-circular plate 8, and the inner walls of the first semi-circular plate 8 and the second semi-circular plate 9 are fixedly connected to a plurality of convex balls 10, and the middle parts of the front and rear sides of the second semi-circular plate 9 are fixedly connected to lifting rings 11;

[0028] Specifically, the setting of the spring 7 can be squeezed and adjusted according to the size of the placed wire harness to ensure that the wire harness is stably limited between the first semi-circular arc plate 8 and the second semi-circular arc plate 9. At the same time, convex balls 10 are provided on the inner walls of both to ensure the stability of the wire harness limitation.

[0029] Further explanation, the bottom of the inner wall of the receiving seat 3 is located just below the second semicircular arc plate 9 and is fixedly connected with a rubber pad 12, the top of the bottom plate 1 is fixedly connected with convex rails 2 on both sides, the inner wall of the receiving seat 3 is slidably connected to the top of the convex rails 2 on both sides, the front and rear sides of the top of the bottom plate 1 are located between the convex rails 2 on both sides and are fixedly connected with telescopic rods 14, and the tops of the telescopic rods 14 on both sides are fixedly connected with receiving plates 15;

The rubber pad 12 can abut against the top of the rubber pad 12 when the second semi-circular plate 9 is adjusted downward. When the connector as a whole is affected by shaking, it can be buffered to avoid being affected. The setting of the convex rails 2 on both sides can conveniently adjust the position of the connector as a whole, so as to facilitate its movement to determine a suitable fixed position. At the same time, the telescopic rods 14 on both sides are pulled or pushed back, and their heights are adjusted so that the receiving plates 15 on both sides can match the height of the wiring harness, so that both ends of the wiring harness can be supported to prevent squeezing or knotting, thereby ensuring the stability of the connection between the wiring harness and the PCB board.
