Description

Technical Field

[0001] The utility model relates to the field of crimping parts, in particular to a C-shaped crimping part for a railway through-ground wire. Background Art

[0002] With the rapid development of my country's high-speed railways, urban subways, light rail construction, passenger dedicated lines, and the speed increase and electrification of ordinary railways, the field of rail transit will have unprecedented development prospects. According to relevant planning estimates, it is expected that about 5 kilometers of through-ground wires will be used for every kilometer of electrified railway, and about 61,000 kilometers of new and renovated lines will be added and renovated in the next 15 years, with an average annual cable consumption of 20,000 kilometers. The through-ground wires used in rail transit signal systems have stable and reliable high conductivity performance, advanced product technology, and long life. However, although the existing C-type connectors for railway through-ground wires have a simple structure, when used, their crimping parts need to be deformed to facilitate the crimping of the wires. This installation method is not conducive to the removal and maintenance of the connectors, and the deformed connectors cannot be reused, resulting in a waste of resources. In addition, the connectors after crimping lack a locking mechanism, which makes the wires easy to fall off.

[0003] In the existing technology, such as the "A C-type crimping piece for railway through-ground wire" with Chinese authorization announcement number: CN217427113U, it includes a main body, an arm is provided on the main body, and the arm is symmetrically provided in two groups, and a stopper is provided on the main body, and a locking mechanism is slidably installed on the stopper, and the locking mechanism includes a pressure plate and a support rod, and pressure blocks are provided at both ends of the pressure plate, and a support rod is fixedly connected to the pressure block, and a pull rod is provided at the upper end of the support rod. Different from the traditional C-type connector, the present device has a simple structure and is easy to use. It can quickly and conveniently install, connect, remove and replace the wires without causing deformation to the connectors, which is convenient for subsequent secondary use and saves installation costs; it can play an anti-slip and fastening role when the wires are pressed together, and avoid the problem of the wires easily slipping off in the case of external collision and pulling, which greatly improves the practicality of the device.

[0004] When the crimping piece is used in the prior art, the spring is prone to elastic deformation when it is compressed, so that the spring is prone to shake when the wire is pulled, which in turn causes the wire to loosen.

[0005] Therefore, it is necessary to provide a railway through-ground wire C-type crimping piece to solve the above technical problems. Utility Model Content

By arranging an anti-slide plate, when the railway through-ground wire is connected and fixed, the wire is sleeved inside the extrusion sleeve, and the extrusion sleeve is compressed at this time, so that the extrusion sleeve can drive the wire to be extruded on the surface of the anti-slide plate when it is bent and deformed, so that the anti-slide plate can greatly improve the friction between the extrusion sleeve and the wire, so that the wire can be extruded and fixed inside the extrusion sleeve, thereby achieving the extrusion and fixing connection effect of the wire, thereby avoiding the problem of poor stability when the spring extrudes the wire to fix it, and thereby improving the stability of the wire connection and fixation;

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a railway through-ground wire C-type crimping piece provided by the utility model; Figure 2 for Figure 1 A front view of an extrusion sleeve in a C-shaped crimping piece for a railway through-ground wire is shown; Figure 3 for Figure 1 A front view of a limit block in a C-type crimping piece for a railway through-ground wire; Figure 4 for Figure 1A front view of an auxiliary mechanism in a C-type crimping piece for a railway through-ground wire is shown. A C-type crimping piece for a railway through-ground wire comprises an extrusion sleeve 1, an anti-corrosion layer 2 is arranged on the outside of the extrusion sleeve 1, a protective sleeve 3 is fixedly sleeved inside the extrusion sleeve 1, a limiting block 4 is fixedly connected to the side of the inner wall of the extrusion sleeve 1, an anti-slip plate 5 is fixedly connected to the front of the limiting block 4, a clamping column 6 is fixedly sleeved on the front of the extrusion sleeve 1, and an auxiliary mechanism 7 is arranged inside the extrusion sleeve 1.

[0025] The material of the anti-skid plate 5 is metal aluminum material, and there are two anti-skid plates 5, and the two anti-skid plates 5 are symmetrically distributed with the limit block 4 as the symmetry axis; by setting the anti-skid plate 5, when the railway through-line is connected and fixed, the wire is sleeved inside the extrusion sleeve 1, and the extrusion sleeve 1 is compressed at this time, so that the extrusion sleeve 1 can drive the wire to be squeezed on the surface of the anti-skid plate 5 when it bends and deforms, so that the anti-skid plate 5 can greatly increase the friction between the extrusion sleeve 1 and the wire, so that the wire can be squeezed and fixed inside the extrusion sleeve 1, thereby achieving the extrusion and fixing connection effect of the wire, thereby avoiding the problem of poor stability when the spring squeezes the wire to fix it, and thereby improving the stability of the wire connection and fixation.

[0026] The thickness of one side of the extrusion sleeve 1 is smaller than the thickness of the other side of the extrusion sleeve 1, and the material of the extrusion sleeve 1 is aluminum alloy. By setting the extrusion sleeve 1, when the wire is extruded and fixed, the extrusion sleeve 1 is compressed so that one side of the extrusion sleeve 1 can be bent inward quickly, so that the extrusion sleeve 1 can be extruded and fixed outside the wire, thereby facilitating the compression of the extrusion sleeve 1.

[0027] The material of the anti-corrosion layer 2 is polyethylene material, and the anti-corrosion layer 2 is compatible with the extrusion sleeve 1; by setting the anti-corrosion layer 2, when the extrusion sleeve 1 is in a humid environment for a long time, the anti-corrosion layer 2 can protect the extrusion sleeve 1, thereby avoiding the problem of water flow corroding the extrusion sleeve 1 for a long time, causing damage to the extrusion sleeve 1, thereby greatly improving the service life of the crimping part.

[0028] The material of the protective sleeve 3 is rubber material, and the thickness of the protective sleeve 3 is the same as the thickness of the anti-corrosion layer 2; by setting the protective sleeve 3, when the wire is extruded and connected, the protective sleeve 3 can separate the wire from the inner wall of the extrusion sleeve 1, thereby avoiding the problem of damage to the wire surface caused by the hard inner wall of the extrusion sleeve 1, thereby achieving the protection effect of the wire when the extrusion sleeve 1 is compressed, that is, improving the protection effect when the wire is connected.

[0029] The limit block 4 is located in the middle of the inner wall side of the extrusion sleeve 1, and the height of the limit block 4 is less than the height of the extrusion sleeve 1; by setting the limit block 4, when the wires are connected, the two wires are sleeved inside the extrusion sleeve 1, and the extrusion sleeve 1 is compressed at this time, so that the limit block 4 can separate the two wires, thereby avoiding the problem of skin damage when the two wires are strongly squeezed, thereby improving the protection effect when the wires are connected.

[0030] The front shape of the clamping column 6 is conical, and the number of the clamping columns 6 is two; by setting the clamping column 6, when the wire connection is fixed, the extrusion sleeve 1 is compressed, so that the extrusion sleeve 1 can drive the clamping column 6 to be squeezed on the surface of the wire, so that the clamping column 6 can greatly increase the friction between the wire and the inner wall of the extrusion sleeve 1, thereby avoiding the problem of the wire shaking inside the extrusion sleeve 1 when the wire is pulled, thereby improving the tightness of the wire after connection.

[0031] The auxiliary mechanism 7 includes an extrusion block No. 1 71, which is movably sleeved inside the extrusion sleeve 1, and an extrusion block No. 2 72 is movably sleeved inside the extrusion sleeve 1. The material of the extrusion block No. 1 71 is rubber material. By setting the auxiliary mechanism 7, when the wire is extruded and connected, the wire is sleeved inside the extrusion sleeve 1. At this time, the extrusion block No. 1 71 and the extrusion block No. 2 72 are sleeved inside the extrusion sleeve 1, so that the extrusion block No. 1 71 and the extrusion block No. 2 72 can squeeze and limit the wire, thereby avoiding the problem that the internal space of the extrusion sleeve 1 is large, resulting in positional displacement of the wire when it moves, and then causing the extrusion sleeve 1 to be inconvenient to compress, thereby improving the convenience of wire compression connection.

[0032] The working principle of the C-type crimping piece for a railway through-ground wire provided by the utility model is as follows:

[0033] The first step: first, when connecting and fixing the railway through-line, the conductor is sleeved inside the extrusion sleeve 1. At this time, the extrusion sleeve 1 is compressed, so that when the extrusion sleeve 1 is bent and deformed, the conductor is driven to be squeezed on the surface of the anti-slide plate 5, so that the anti-slide plate 5 can greatly increase the friction between the extrusion sleeve 1 and the conductor, so that the conductor can be squeezed and fixed inside the extrusion sleeve 1, thereby achieving the extrusion and fixing connection effect of the conductor, thereby avoiding the problem of poor stability when the spring extrudes the conductor to fix it, thereby improving the stability of the conductor connection and fixation. When the conductor is extruded and fixed, the extrusion sleeve 1 is compressed, so that one side of the extrusion sleeve 1 can be bent inward quickly, so that the extrusion sleeve 1 can be squeezed and fixed on the outside of the conductor, thereby facilitating the compression of the extrusion sleeve 1. When the extrusion sleeve 1 is in moisture for a long time, the extrusion sleeve 1 is wet. In a wet environment, the anti-corrosion layer 2 can protect the extrusion sleeve 1, so as to avoid the problem that the extrusion sleeve 1 is damaged due to long-term corrosion of the water flow, thereby greatly improving the service life of the crimping part. When the wire is extruded and connected, the protective sleeve 3 can separate the wire from the inner wall of the extrusion sleeve 1, so as to avoid the problem that the inner wall of the extrusion sleeve 1 is relatively hard and causes the surface of the wire to be damaged, thereby achieving the protective effect of the wire when the extrusion sleeve 1 is compressed, that is, the protective effect when the wire is connected is improved. When the wire is connected, the two wires are sleeved inside the extrusion sleeve 1. At this time, the extrusion sleeve 1 is compressed, so that the limit block 4 can separate the two wires, so as to avoid the problem that the skin of the two wires is damaged when they are strongly squeezed, thereby improving the protective effect when the wire is connected;

[0034] Step 2: When the wire is connected and fixed, compress the extrusion sleeve 1 so that the extrusion sleeve 1 can drive the clamping column 6 to be squeezed on the surface of the wire, so that the clamping column 6 can greatly increase the friction between the wire and the inner wall of the extrusion sleeve 1, thereby avoiding the problem of the wire shaking inside the extrusion sleeve 1 when the wire is pulled, thereby improving the tightness of the wire after connection. When the wire is extruded and connected, the wire is sleeved inside the extrusion sleeve 1. At this time, the first extrusion block 71 and the second extrusion block 72 are sleeved inside the extrusion sleeve 1, so that the first extrusion block 71 and the second extrusion block 72 can squeeze and limit the wire, thereby avoiding the problem that the internal space of the extrusion sleeve 1 is large, resulting in positional displacement when the wire moves, and then causing the compression of the extrusion sleeve 1 to be inconvenient, thereby improving the convenience of wire compression connection.

[0035] Compared with the related art, the C-type crimping piece for railway through-ground wire provided by the utility model has the following beneficial effects:

[0036] By providing the anti-skid plate 5, when the railway through-line is connected and fixed, the wire is sleeved inside the extrusion sleeve 1. At this time, the extrusion sleeve 1 is compressed, so that the extrusion sleeve 1 is bent and deformed to drive the wire to be squeezed on the surface of the anti-skid plate 5, so that the anti-skid plate 5 can greatly increase the friction between the extrusion sleeve 1 and the wire, so that the wire can be squeezed and fixed inside the extrusion sleeve 1, thereby achieving the effect of squeezing and fixing the wire, thereby avoiding the problem of poor stability when the spring squeezes the wire to fix it, and thus improving the stability of the wire connection and fixation.
