Referring to FIGS. 1 and 2, an embodiment of the present utility model provides a connector for preventing signal interference, comprising a plurality of groups of wires 10 and spacers 20 for separating two adjacent groups of the wires 10, wherein the wires 10 comprise signal wires 102 and ground wires 103, the ground wires 103 are connected on both sides of the signal wires 102, and a wire shielding layer 101 is sleeved between the signal wires 102 and the ground wires 103; a wire clamp 30 is mounted on the spacer 20, a plurality of bosses 201 are arranged on the spacer 20, the wire clamp 30 is provided with a plurality of staggered holes 301 matched with the bosses 201 and signal wire holes 302 matched with the signal wires 102; and the wire clamp 30 and the bosses 201 are snap-fitted via the staggered holes 301, and the wire shielding layer 101 is connected to the signal wire holes 302.

According to the present utility model, the wire clamp 30 is arranged between the wire 10 and the spacer 20, and the staggered hole 301 in the wire clamp 30 and the boss 201 on the spacer 20 are snap-fitted, such that a signal on the spacer 20 is guided to sequentially flow to the boss 201, the wire clamp 30 and the wire shielding layer 101, which, in turn, prevents the signal on the spacer 20 from dispersing all around, avoids signal interference among the wires 10, improves the signal connection stability of the connector, and enhances the performance stability of the connector.

Specifically, in this embodiment, the spacer 20 is connected to the wire clamp 30 through the snap-fitting action of the boss 201 and the staggered hole 301, and the wire clamp 30 is designed not only to fix the relative positions of the wire 10 and the spacer 20, but also to guide the flow direction of a signal on the spacer 20, such that the signal current guiding function of the connector is stronger and the performance is more stable, and in order to fix the wire clamp 30 more firmly on the spacer 20, the boss 201 may further be provided with a rotatable buckle or the like to fix the wire clamp 30.

Since the signal current on the spacer 20 needs to flow to the wire clamp 30 through the boss 201, referring to FIGS. 2 and 5, inner walls of the staggered hole 301 and the boss 201 are in interference-fit connection on at least one surface, so as to enable a normal signal transmission between the boss 201 and the staggered hole 301. However, in order to connect the inner wall of the staggered hole 301 to the boss 201, the size of the staggered hole 301 is required to be particularly precise such that the staggered hole 301 and the boss 201 are attached tightly, and meanwhile, this operation also increases the difficulty in snap-fitting of the wire clamp 30 and the boss 201, which not only requires a greater force to assemble the wire clamp 30 to the boss 201, but is also likely to cause the wire clamp 30 or the boss 201 to break due to an excessive force during the assembly process. As such, referring to FIG. 4, one group of symmetrical inner side surfaces of the staggered hole 301 are provided as curved surface structures. Any one of the curved surface structures comprises a first convex surface 3011 and a second concave surface 3012, and a distance(S) between the first convex surface 3011 and the second concave surface 3012 is set to 0.016 cm. A width of the boss 201 is set to 0.15 cm and a width of the staggered hole 301 is set to 0.152 cm. It is ensured that inner walls of the staggered hole 301 and the boss 201 are in interference-fit connection on at least one surface on the premise of convenient mounting, and therefore, the signal current is ensured to be able to pass smoothly.

Referring to FIGS. 1 and 2, the ground wire 103 is arranged in a bent manner, and the ground wire 103 is welded to the wire clamp 30 and the spacer 20. The ground wire 103 is bent by 90 degrees and welded to a side wall of the wire clamp 30, and extends to be partially welded to the spacer 20. The ground wire, the wire clamp, and the spacer are fixed together through soldering tin, ensuring the structural stability.

Referring to FIG. 1, the connector further comprises an elastic piece 40 and a PCB board 50, wherein one end of the elastic piece 40 is connected to the wire 10, and the other end of the elastic piece 40 is connected to the PCB board 50. Both ends of the elastic piece 40 are respectively linked with the wire 10 and the PCB board 50, so as to facilitate the signal transmission between the wire 10 and the PCB board 50. Since the spacers 20 are arranged between two adjacent groups of the wires 10 and between the elastic pieces 40 at intervals, the signal current flows on the spacer 20 as well. Similarly, the boss 201 and the spacer 20 are designed by one-piece molding, so the signal current flows on the boss 201 as well. Finally, the boss 201 guides the signal current to flow to the wire clamp 30 and the wire shielding layer 101, such that the interference caused between the signal wires 102 is affected because the signal current is prevented from dispersing all around the spacer 20.

Referring to FIG. 1, the wire clamp 30 is provided as a structure made of hardware materials. Since the wire clamp 30 has the function of guiding the signal current, the wire clamp 30 is provided as a structure made of conductive materials such as brass, stainless steel plating, etc., so as to ensure the wire clamp 30 to perform the conductive function. Similarly, the wire shielding layer 101 is provided as a structure made of conductive aluminum foil, an outer wall of the wire shielding layer 101 is in contact with the signal wire hole 302, such that the signal current on the wire clamp 30 can flow to the wire shielding layer 101.

In order to ensure the safety of the connector during use, referring to FIG. 2, the wire 10 further comprises an insulating layer 104, and the insulating layer 104 is sleeved on an outermost layer of the wire 10. The insulating layer 104 is sleeved on the outermost layer of the wire 10 to insulate and protect the wire 10, such that the safety is improved.

Referring to FIG. 1, the connector further comprises a fixed piece 60, wherein the fixed piece 60 is arranged at a periphery of the spacer 20, and the fixed piece 60 is in snap-fit connection with the spacer 20. The fixed piece 60 is provided as a plastic one-piece molded structure. The plastic material is of a certain elasticity, which allows the fixed piece 60 to be tightly snap-fitted outside the spacer 20, function as a buffer protection for the entire connector, and serve the purpose of insulation protection, such that the safety of the connector is improved.

The above mentioned contents are only optional embodiments of the present utility model and are not intended to limit the patent scope of the present utility model, and under the inventive concept of the present utility model, the equivalent structural transformations made by using the contents of the specification and the drawings of the present utility model, or direct/indirect applications to other related technical fields, are all included in the patent protection scope of the present utility model.
