Detailed Description

As shown in FIGS. 1 and 2, the signal connector of the present invention comprises a main frame, a connecting terminal, and a connecting cover plate, the left positioning plate insert and the right positioning plate insert are inserted into the right side of the main body frame, and the right positioning plate insert is connected with the positioning shaft block on the right side of the middle part of the connecting cover plate in a positioning mode.

In the scheme, the structurally-enhanced positioning shaft block is adopted to replace the structurally-enhanced signal connector scheme for connecting the shaft heads on the two sides of the cover plate, as shown in fig. 2, the connecting cover plate 300 is pressed on the left positioning plate insert 410 and the right positioning plate insert 420 through the positioning shaft block 320, and the positioning shaft block 320 remarkably enhances the structural strength compared with the beam shaft 310, so that the possibility of fracture is reduced in the using process. Therefore, compared with the existing like products, the scheme enhances the structural performance and prolongs the service life.

Based on above scheme, this scheme discloses a concrete location axle piece, as shown in fig. 2, the radial dimension of the location axle piece of this scheme is greater than the radial dimension of beam axle, and the junction of location axle piece and the one side of the middle part of connecting the apron is equipped with the strengthening rib structure that the cross-section is wedge-shaped. The positioning shaft block 320 is in a special-shaped design, only the head part is in a circular arc shape, smooth rotation is guaranteed, the rest parts are reinforced in a square shape, and in view of the fact that the joint of the synchronous side shafts belongs to a stress concentration point, an oblique angle transition structure is adopted for reinforcement at the position.

In order to meet the stability of component connection and realize the positioning connection between the upper part of the connecting cover plate and the frame top plate, as shown in fig. 2 and 3, a foot-chamfering groove is arranged at the intersection of the upper part of the connecting cover plate and the outer side front end edge of the frame top plate, and the foot-chamfering groove and the outer side front end edge of the frame top plate form positioning clamping connection. The connection cover plate 300 is provided with a reversed leg groove 301, so that the connection cover plate 300 is limited to slide downwards when external force is applied, and the force is prevented from being transmitted to the positioning shaft block 320 and the beam shaft 310 to cause damage. Based on above scheme, in order to further improve the stability of part connection, as shown in fig. 3, the location axle piece of this scheme forms the location connection that compresses tightly based on contact internal stress with left locating plate mold insert, right locating plate mold insert, and contact internal stress forms reverse moment through the pivot fulcrum of location axle piece, and reverse moment compresses tightly the back-foot groove and fixes a position on the outside front end border of frame roof. The bottom of the positioning shaft block 320 is an inclined plane and is designed to interfere with the right positioning plate insert 420, so that upward elastic force is generated, and a moment tending to rotate rightwards is formed with a rotating shaft fulcrum, so that the pin inverting groove 301 is tightly attached to the front end edge of the outer side of the frame top plate 110, the state of the connecting cover plate 300 is stable, and the connecting cover plate 300 cannot be rotated and closed or positioned irregularly due to vibration and misoperation.

In order to avoid the sliding between the upper row contact pins and the inner side of the frame top plate and influence the positioning stability, as shown in fig. 2 and 4, a plurality of bump structures are arranged on the contact connection surface of the upper row contact pins of the U-shaped bent frame and the inner side of the frame top plate, and the bump structures and the inner side of the frame top plate form contact internal stress to compress and position the connection. Similarly, in order to avoid the sliding between the upper row contact pins and the inner side of the frame top plate and influence the positioning stability, as shown in fig. 2 and 4, a positioning clamping groove is arranged on the surface of the upper row contact pins of the U-shaped bent frame in the scheme, the front end of the inner side of the frame top plate abuts against the front end of the positioning clamping groove for positioning connection, and the rear end of the inner side of the frame top plate abuts against the rear end of the positioning clamping groove for positioning connection.

In order to improve the welding effect between the welding surface of the welding end of the U-shaped bent and the circuit board, as shown in fig. 4, the welding surface of the welding end of the U-shaped bent and the welding plane of the circuit board are arranged in an inclined manner. Because the part size is less, and the intensity is also less strong behind the welding plate, receives unusual external force in the operation process, and the connector can appear not hard up or break away from PCB, and for strengthening welding stability, the face of weld of this scheme is the inclined plane, follows the inclined plane siphon during the welding, and it is effectual to climb tin, and welding strength is high.
