Description

Technical Field

[0001] The utility model relates to the technical field of shunt wires, in particular to a shunt wire joint drilling jig. Background Art

[0002] Pantograph shunt conductors are key components in electrified railway power supply systems. Made of high-quality braided copper wire, these conductors are fitted with specially designed terminals at both ends to ensure a secure connection. Their primary function is to effectively divert electrical energy drawn from the overhead catenary to the railway vehicle's power supply system when the pantograph makes contact with the grid, ensuring stable current transmission. By optimizing current distribution, pantograph shunt conductors not only improve electrified railway operating efficiency but also enhance system safety, reducing the risks of current overloads and leakage, and providing a safer and more reliable travel environment for passengers and staff.

[0003] The shunt conductor connector is screwed to the pantograph, requiring a mounting hole to be drilled. During drilling, the gap between the shunt conductor and the terminal allows for relative movement, which can easily lead to burrs and even copper wire entanglement in the drill bit. Furthermore, the terminal is prone to deformation during drilling. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a shunt wire joint drilling jig.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A drilling jig for a shunt wire joint includes a mounting base with a detachable cover plate on the mounting base. A pressing space for accommodating a terminal is formed between the cover plate and the mounting base. Both the cover plate and the mounting base are provided with through holes, and the two through holes are aligned.

[0007] Preferably, a positioning pin is provided between the mounting seat and the cover plate.

[0008] Preferably, the cover plate and the mounting seat are detachable by being screwed together.

[0009] Preferably, both sides of the mounting seat are provided with step surfaces.

[0010] Preferably, a mounting groove is provided on the end surface of the mounting seat, and the cover plate closes the top opening of the mounting groove to form the pressing space.

[0011] Preferably, a positioning plate is slidably provided on the side wall of the mounting seat, and the sliding positioning plate can abut against the terminal and restrict the terminal from detaching from the pressing space.

[0012] Preferably, a guide block is provided on the side wall of the mounting seat, a waist-shaped hole is opened on the positioning plate, and the guide block is adapted to fit in the waist-shaped hole.

[0013] Preferably, a handle bolt is also provided on the positioning plate.

[0014] Preferably, the guide block is screwed to the mounting seat.

[0015] Preferably, a limit plate is sleeved on the bolt of the guide block, and the limit plate is attached to the positioning plate.

[0016] The beneficial effect of this utility model is that when the shunt wire connector is placed within the compression space of the drill jig, the gap between the shunt wire and the terminal is eliminated by the compression of the cover plate. The drill bit is then passed through the through hole to drill the mounting hole for the connector. Compared with the existing technology, the utility model can eliminate the gap between the shunt wire and the terminal, making it less likely that burrs will form on the shunt wire during drilling and that copper wire will become entangled in the drill bit. Furthermore, the terminal is less likely to deform under pressure due to the limited compression space. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0021] like Figure 1 、 Figure 2As shown, a drilling jig for a shunt conductor connector includes a mounting base 1 with a mounting slot 7 defined on its end surface. The top and sides of the mounting slot 7 are open, and a removable cover plate 2 is provided on the mounting base 1 to seal the top opening of the mounting slot 7. It will be understood that the mounting base 1 and the cover plate 2 enclose a press-fit space 3 at the mounting slot 7, into which the shunt conductor connector extends. Furthermore, both the cover plate 2 and the mounting base 1 have through-holes 4, which are aligned.

[0022] When drilling, the cover plate 2 can be removed first, and the shunt wire connector can be placed in the installation groove 7; then the cover plate 2 can press the shunt wire connector into the pressing space 3, thereby eliminating the gap between the shunt wire and the terminal, so that the quality of the drill bit drilling the connector through the through hole 4 is higher.

[0023] In a possible example, the mounting groove 7 can be formed on the end surface of the cover plate 2 facing the mounting seat 1, or the mounting groove 7 can be divided into two aligned parts and distributed on the cover plate 2 and the mounting seat 1 respectively. The present invention does not limit how the mounting seat 1, the cover plate 2, and the mounting groove 7 cooperate to form the press-fit space 3.

[0024] For example, the mounting base 1 and cover plate 2 are screwed together to achieve detachability. When the connector is placed in the press-fit space 3, simply loosen the screws on the cover plate 2 without removing the entire cover plate 2. Furthermore, a locating pin 5 is preferably provided between the mounting base 1 and the cover plate 2. This locating pin 5 improves the positioning accuracy of the drilling jig, particularly ensuring the positioning accuracy of the through hole 4 and the connector, thereby achieving higher positioning accuracy for the drilled mounting hole.

[0025] In some embodiments, both sides of the mounting base 1 are provided with stepped surfaces 6, which makes it easier for the mounting base 1 to be securely mounted and accurately positioned on a drilling machine or a CNC milling machine. For example, the stepped surfaces 6 can be clamped on the drilling machine using a vise-like fixture.

[0026] In a preferred embodiment, a positioning plate 8 is slidably mounted on the side wall of the mounting base 1. Once the connector is placed in the press-fit space 3, the positioning plate 8 can be slid to abut the terminal, preventing it from slipping out of the press-fit space 3. Simultaneously, the abutment of the positioning plate 8 positions the terminal axially, further ensuring the positional accuracy of the drilled mounting hole.

[0027] For example, a guide block 9 is provided on the side wall of the mounting base 1 by screwing and pressing, and a waist-shaped hole 10 is correspondingly provided on the positioning plate 8. The guide block 9 and the waist-shaped hole 10 are guided and adapted to enable the positioning plate 8 to slide in and out of the pressing space 3. In addition, a limit plate 12 is sleeved on the bolt of the guide block 9. When the bolt is tightened, the limit plate 12 can be driven to fit the positioning plate 8, thereby preventing the waist-shaped hole 10 from separating from the guide block 9, and improving the sliding reliability of the positioning plate 8.

[0028] The positioning plate 8 may also be provided with a handle bolt 11 or a conventional hexagonal head bolt for the operator to grasp, thereby facilitating the sliding control of the positioning plate 8 .

[0029] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
