Description

Technical Field

[0001] This utility model relates to the field of cable connection technology, specifically a cable connection device for power engineering. Background Technology

[0002] In the field of power engineering, cable connection devices, as key components, bear the important responsibility of ensuring stable power transmission. With the continuous expansion and increasing complexity of power systems, the performance requirements for cable connection devices are becoming increasingly stringent. Although traditional cable connection devices can meet basic conductivity and connection requirements, they have significant shortcomings in terms of sealing. In the complex and ever-changing power engineering environment, adverse factors such as humidity, dust, and corrosive chemical gases can easily penetrate through the gaps at the connection points, leading to problems such as decreased insulation performance, short circuits, and even equipment failures at the cable connection points. This poses hidden dangers to the safe and reliable operation of the power system, causing huge economic losses and social impacts.

[0003] The sealing structures of existing cable connection devices are mostly rudimentary in design. For example, some devices rely solely on simple rubber gaskets for sealing. This type of sealing method is prone to performance degradation when faced with long-term mechanical vibration, thermal expansion and contraction, and changes in external environmental pressure. The rubber gaskets may age and deform, failing to fit tightly against the connection points, leading to sealing failure. Furthermore, improper operation during the installation and disassembly of cable connection devices can easily damage the sealing components, further exacerbating the sealing problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cable connection device for power engineering, which has advantages such as good connection and sealing effect, and solves the problem of poor cable connection and sealing effect in existing technologies.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable connection device for power engineering, comprising:

[0006] The connection mechanism includes a cable connection assembly and sealing assemblies disposed at both ends of the cable connection assembly;

[0007] The cable connection assembly includes two sets of connection shells, which are interlocked with each other, and the inner walls of the two sets of connection shells are provided with connectors.

[0008] The sealing assembly includes threaded rings respectively disposed at both ends of the two sets of connecting shells. A clamping ring is threadedly connected to the outer side of the threaded ring. A hinge is provided on the inner wall of both the upper and lower sides of the clamping ring. A rotating plate is hinged to the outer side of the hinge on both the upper and lower sides. A sealing gasket is provided on the opposite side of the two sets of rotating plates. A plug ring is provided at the end of the threaded ring away from the connecting shell.

[0009] Furthermore, both the threaded ring and the connecting shell are semi-circular in shape, and the inner wall of the clamping ring is provided with a thread that matches the threaded ring.

[0010] Furthermore, both the rotating plate and the insertion ring are conical in shape, the sealing gasket is semi-circular in shape, and the sealing gasket is an elastic sealing ring.

[0011] Furthermore, the upper connecting shell has several sets of pins on the side near the lower connecting shell, and the lower connecting shell has positioning pin holes on the side near the upper connecting shell that correspond to the positions of the several sets of pins.

[0012] Furthermore, the connector includes a base respectively disposed on the inner wall of the two sets of connecting shells. The top of the lower base is provided with several sets of wire grooves for cable harnesses to be placed in, and the bottom of the upper base is provided with elastic members corresponding to the positions of the several sets of wire grooves. The bottom of the elastic members is provided with wire pressing parts.

[0014] Furthermore, the width of the pressing part is equal to the width of the inner cavity of the wire groove, and an arc-shaped opening is provided at one end of the pressing part near the wire groove.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. This cable connection device for power engineering, through the design of sealing components at both ends of the connection device, including threaded rings, compression rings, rotating plates, sealing gaskets, and plug rings, can achieve a tight seal at the cable connection point. This effectively prevents external humid air, dust, and corrosive chemical gases from entering the cable connection area, thereby avoiding problems such as decreased insulation performance, short circuits, and equipment failures caused by these external factors. It improves the stability and reliability of the cable connection device in complex and ever-changing power engineering environments, ensures the safe operation of the power system, and reduces economic losses and safety hazards caused by poor sealing.

[0017] 2. The cable connection device for this power engineering project has interlocking connecting shells at both ends. The upper connecting shell is equipped with several sets of pins, and the lower connecting shell has corresponding positioning pin holes. This structural design enables the cable connection device to achieve precise positioning and stable interlocking at both ends. At the same time, the cooperation between the elastic element and the wire pressing part in the connector can firmly press the cable bundle into the wire groove, ensuring the tightness of the cable connection. This stable connection method can effectively resist the influence of external mechanical vibration and thermal expansion and contraction on the stability of the cable connection, ensuring the long-term reliability of the cable connection and reducing the risk of power transmission failure due to loose connection.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-4 The cable connection device for power engineering in this embodiment includes a connection mechanism 1, a cable connection assembly 11, and sealing assemblies 12 disposed at both ends of the cable connection assembly 11.

[0025] The cable connection assembly 11 includes two sets of connection shells 111, which are interlocked. The inner walls of the two sets of connection shells 111 are provided with connectors 112. The connection shells 111 of the cable connection device are in a separated state. Then, the cables are connected by the relevant structures on the connection shells 111. Specifically, the two cable segments are respectively placed into the interior of the corresponding connection shells 111, and then the two sets of connection shells 111 are interlocked to combine them together.

[0026] The sealing assembly 12 includes threaded rings 121 respectively disposed at both ends of two sets of connecting shells 111. A clamping ring 122 is threadedly connected to the outer side of the threaded ring 121. A hinge 123 is disposed on the inner walls of both the upper and lower sides of the clamping ring 122. A rotating plate 124 is hinged to the outer side of both the upper and lower hinges 123. A sealing gasket 125 is disposed on the opposite side of both sets of rotating plates 124. A plug ring 126 is disposed at the end of the threaded ring 121 away from the connecting shell 111.

[0027] Example 2: Based on Example 1, this example includes a connecting mechanism 1, a cable connecting assembly 11, and sealing assemblies 12 disposed at both ends of the cable connecting assembly 11.

[0028] In this embodiment, the cable connection assembly 11 includes two sets of connection shells 111, which are interlocked with each other, and the inner walls of the two sets of connection shells 111 are provided with connectors 112.

[0029] In this embodiment, the sealing assembly 12 includes threaded rings 121 respectively disposed at both ends of the two sets of connecting shells 111. A clamping ring 122 is threadedly connected to the outer side of the threaded ring 121. After the snap-fit ​​is completed, the clamping ring 122 previously fitted onto both ends of the cable is moved to the threaded rings 121 at the corresponding ends of the connecting shells 111, and the tightening operation begins. As the threaded connection between the clamping ring 122 and the threaded ring 121 is gradually tightened, hinges 123 are provided on the inner walls of both the upper and lower sides of the clamping ring 122, and rotating plates 124 are hinged to the outer sides of both the upper and lower hinges 123. A sealing gasket 125 is provided on the opposite side of both sets of rotating plates 124, and a plug ring 126 is provided at the end of the threaded ring 121 away from the connecting shell 111.

[0030] Specifically, the clamping ring 122 continuously approaches the threaded ring 121. During this process, the end of the clamping ring 122 gradually inserts into the gap between the rotating plate 124 and the clamping ring 122. As the clamping ring 122 continues to tighten, the insertion ring 126 further penetrates into the space between the rotating plate 124 and the clamping ring 122. The conical structure of the insertion ring 126 pushes the rotating plate 124 to rotate along the hinge 123. During the rotation of the rotating plate 124, the sealing gasket 125 on its opposite side gradually presses against the outer surface of the cable, thereby achieving a sealing effect.

[0031] In this embodiment, the threaded ring 121 and the connecting shell 111 are both set to a semi-circular shape, and the inner wall of the clamping ring 122 is provided with a thread that matches the threaded ring 121.

[0032] In this embodiment, the rotating plate 124 and the plug ring 126 are both conical in shape, and the sealing gasket 125 is semi-circular in shape. The sealing gasket 125 is an elastic sealing ring. Under the continuous tightening force of the clamping ring 122, the sealing gasket 125 is tightly attached to the cable surface to form an effective sealing layer, preventing external moisture, dust and other harmful substances from entering the cable connection part.

[0033] In this embodiment, the upper connecting shell 111 is provided with a number of sets of pins 113 on the side near the lower connecting shell 111, and the lower connecting shell 111 is provided with positioning pin holes 114 corresponding to the positions of the sets of pins 113 on the side near the upper connecting shell 111.

[0034] In this embodiment, the connector 112 includes a base 1121 respectively disposed on the inner wall of two sets of connecting shells 111. The top of the lower base 1121 is provided with several sets of wire grooves 1122 for cable harnesses to be placed in. The bottom of the upper base 1121 is provided with elastic members 1123 corresponding to the positions of the several sets of wire grooves 1122. The bottom of the elastic member 1123 is provided with a wire pressing part 1124.

[0035] In this embodiment, the elastic element 1123 includes a connecting block 11231 disposed at the bottom of the upper base 1121, and a spring telescopic rod 11232 disposed inside the connecting block 11231. The pressing part 1124 is fixedly connected to the bottom of the spring telescopic rod 11232.

[0036] Specifically, the two sets of connecting shells 111 are assembled together by interlocking. The pin 113 on the upper connecting shell 111 and the positioning pin hole 114 on the lower connecting shell 111 cooperate with each other to achieve accurate positioning and initial fixation of the connecting shell 111. On the inner wall of the connecting shell 111, the wire groove 1122 on the lower base 1121 is used to place the cable harness. After the connecting shell 111 is assembled, the elastic element 1123 on the upper base 1121 will press down the cable harness with the wire pressing part 1124 at the bottom of the elastic element 1123, and fix it firmly in the wire groove 1122.

[0037] It should be noted that the spring telescopic rod 11232 is a set of telescopic rods with an inner rod and an outer tube, and a spring is fitted on the outside of the telescopic rod.

[0038] In this embodiment, the width of the pressing part 1124 is equal to the width of the inner cavity of the wire groove 1122, and an arc opening is provided at one end of the pressing part 1124 near the wire groove 1122.

[0039] It should be noted that the arc-shaped opening can be adapted to wire harnesses to increase the contact area and improve the fixing effect.

[0040] The working principle of the above embodiments is as follows:

[0041] (1) When starting the cable connection operation, firstly, put the two clamping rings 122 into the two ends of the cable to be connected. At this time, the connecting shells 111 of the cable connection device are in the open state. Then, use the relevant structure on the connecting shells 111 to connect the cables. Specifically, put the two cable segments into the corresponding connecting shells 111 respectively. Then, snap the two sets of connecting shells 111 together to form the main structure of the cable connection device. After snapping, move the clamping rings 122 that were previously put into the two ends of the cable to the threaded rings 121 at the two ends of the corresponding connecting shells 111 and start the tightening operation. As the threaded connection between the clamping rings 122 and the threaded rings 121 is gradually tightened, the clamping rings 122 continuously move towards the threaded rings. As the plate approaches, the end of the clamping ring 122 gradually inserts into the gap between the rotating plate 124 and the clamping ring 122. As the clamping ring 122 tightens, the insertion ring 126 further penetrates into the space between the rotating plate 124 and the clamping ring 122. The conical structure of the insertion ring 126 pushes the rotating plate 124 to rotate along the hinge 123. During the rotation of the rotating plate 124, the sealing gasket 125 on its opposite side gradually presses against the outer surface of the cable, thereby achieving a sealing effect. Finally, under the continuous tightening force of the clamping ring 122, the sealing gasket 125 is tightly attached to the surface of the cable, forming an effective sealing layer to prevent external moisture, dust and other harmful substances from entering the cable connection part.

[0042] (2) The two sets of connecting shells 111 are combined together by interlocking. The pin 113 on the upper connecting shell 111 and the positioning pin hole 114 on the lower connecting shell 111 cooperate with each other to achieve accurate positioning and initial fixation of the connecting shell 111. On the inner wall of the connecting shell 111, the wire groove 1122 on the lower base 1121 is used to place the cable harness. After the connecting shell 111 is assembled, the elastic element 1123 on the upper base 1121 will press down the cable harness with the wire pressing part 1124 at the bottom of the elastic element 1123 to firmly fix it in the wire groove 1122. The elasticity of the elastic element 1123 can also adapt to the small size changes of the cable harness, ensuring the tightness and reliability of the connection, thereby ensuring the stable power transmission at the cable connection.
