[0002] Rail lead wire is a special cable for railway signal equipment. In the track circuit, it is the connecting wire that leads from the rail to various electrical appliances at the receiving and transmitting ends. The track circuit uses the rail as a conductor to check the train occupancy status of the line section. It is an important infrastructure in the railway signal control system. The outer sheath of the cable is covered on the outside of the cable, and the end of the cable extends out of the outer sheath of the cable to connect with the connecting wire ring. One end of the ordinary connecting wire ring is connected to the rail, and the other end is locked and crimped with the extended cable. There is a gap between the connecting wire ring and the outer sheath of the cable. The two cannot be pressed together, resulting in rainwater infiltrating into the outer sheath of the cable and causing the core wire to rust. At the same time, the manufacturing process of the ordinary connecting wire ring has a pressing crease that concentrates the stress at the crease. The connecting wire ring has no natural angle with the plane of the rail wall, which aggravates the vibration stress at the crease, resulting in the poor impact and vibration resistance of the connecting wire ring, and it is easy to break at the crease.

[0023] Embodiment 1:
[0024] In this embodiment, a connecting wire ring, such as Figures 1 to 3As shown, it includes a wire loop body. Specifically, the wire loop body includes an integrally formed flat section 1 and a straight section 2. The flat section 1 is provided with a nail hole 3 for connecting with the rail. A steel nail is passed through the nail hole 3 to connect the flat section 1 with the rail. The straight section 2 is provided with a first fixing hole 4 for crimping and fixing the protruding end of the cable 11 and a second fixing hole 5 for crimping and fixing the end of the cable outer sheath 12. The first fixing hole 4 is a blind hole. The diameter of the first fixing hole 4 is smaller than the diameter of the second fixing hole 5. The first fixing hole 4 and the second fixing hole 5 are coaxially arranged, and a step surface 6 for limiting the end face of the cable outer sheath 12 is formed between the first fixing hole 4 and the second fixing hole 5.
[0025] By adopting this structure, the protruding end of the cable 11 is inserted into the above-mentioned first fixing hole 4 and locked and crimped, and the cable outer sheath 12 is inserted into the above-mentioned second fixing hole 5 and locked and crimped. At the same time, the cable 11 and the cable outer sheath 12 are tightened, the overall structural strength is improved, the gap between the above-mentioned wire ring body and the cable outer sheath 12 is eliminated, the connection sealing and the waterproof and rust-proof effects are improved, and the practicality of the utility model is stronger.
[0026] In this embodiment, Figure 1 As shown, the flat section 1 is bent at 30° relative to the extension line of the center line of the straight section 2. The flat section 1 and the straight section 2 are connected at a transition point of an arc 7. The 30° bend matches the natural angle formed between the wire loop body and the plane of the rail wall. The bending position adopts an arc 7 for transition without a pressed crease, thereby eliminating the weak link of stress concentration in the wire loop body, improving vibration resistance, and facilitating installation.
[0027] As a specific implementation of this embodiment, Figure 1 and Figure 2 As shown, the straight cylinder section 2 includes an integrally formed first straight cylinder 21 and a second straight cylinder 22, the second fixing hole 5 is radially aligned with the second straight cylinder 22, the outer diameter of the first straight cylinder 21 is smaller than the outer diameter of the second straight cylinder 22, and a slope surface 8 is formed between the first straight cylinder 21 and the second straight cylinder 22.
[0028] Further, such as Figures 1 to 3 As shown, it also includes a wire loop sheath 9, one end of the wire loop sheath 9 is sleeved on the outside of the straight tube section 2, and the other end of the wire loop sheath 9 is sleeved on the outside of the cable outer sheath 12. The wire loop sheath 9 is sleeved on the outside of the straight tube section 2 and the cable outer sheath 12, thereby improving the overall waterproof effect, and further improving the locking and crimping stability of the wire loop sheath 9 and the cable 11 and the cable outer sheath 12, thereby improving the connection strength.
[0029] As an optimization, the wire ring sheath 9 is interference fit with the straight tube section 2 and the cable outer sheath 12 to prevent rainwater from seeping in from the gap between the wire ring sheath 9 and the straight tube section 2 and the cable outer sheath 12 and corroding the core wire.
[0030] In this embodiment, Figure 1 and Figure 2 As shown, an annular groove 10 is provided in the middle of the inner wall of the wire loop sheath 9, and the second straight cylinder 22 is engaged in the annular groove 10. Through the engagement of the annular groove 10 and the second straight cylinder 22, the position of the wire loop sheath 9 is fixed to prevent the wire loop sheath 9 from moving left and right.
[0031] In this embodiment, Figure 3 As shown, the wire ring body, wire ring sheath 9 and cable outer sheath 12 are all structural parts made of transparent insulating materials. Compared with traditional black insulating materials, they are not only more resistant to aging, but also convenient for people to observe the condition of the core wire in the wire ring body.
[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
