Description

Technical Field

[0001] This utility model relates to the field of cable technology, and more specifically to a gel-type protection device for cable joints and cable terminals. Background Technology

[0002] Cables are typically rope-like cables made up of several or groups of conductors twisted together. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer and is used to transmit electricity or information. A cable joint is a component used to connect the various segments into a whole and is located in the middle of the cable line. A cable terminal is a device that is assembled at the beginning and end of a cable line to complete the connection with other electrical equipment.

[0003] Gel-type protection devices are devices that use gel as the main material to provide waterproofing, insulation, and sealing protection. By filling the cable joint protection box with gel, the cable joint is completely wrapped in gel. They are commonly used in underground cable joints, cable joints in distribution cabinets, and other scenarios. They can effectively prevent moisture and impurities from entering and provide reliable insulation and sealing protection.

[0004] Considering that existing gel-type protection devices require bolts to fix the protection box to the cable joint during use to protect the cable joint, and since the protection box usually does not have a device to fix the cable joint, it is difficult to keep the cable joint fixed in the center of the protection box. As a result, when the gel is poured into the protection box, it is difficult to completely cover the cable joint, which reduces the coverage of the gel on the cable joint. After long-term use, it is easy to fall off, resulting in a reduction in the use effect and protection effect of the gel-type protection device. Utility Model Content

[0005] The purpose of this invention is to provide a gel-type protective device for cable joints and cable terminals.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A gel-type protective device for cable joints and cable terminations is provided, comprising two protective housings, a mounting mechanism, and a fixing mechanism. The two protective housings are connected by a mounting plate and side wing plates. The mounting mechanism is used to limit the mounting plate and side wing plates. The fixing mechanism is fixedly installed on the inside of one protective housing and is used to fix the cable. The top of the other protective housing has an injection hole.

[0008] The fixing mechanism includes a support plate and two arc-shaped plates. The support plate is fixedly installed inside a protective shell, and the two arc-shaped plates are slidably installed on the support plate via two guide rods. The clamping and fixing effect of the two arc-shaped plates on the cable ensures that the cable connector remains in the center position inside the protective shell at all times.

[0009] Furthermore, the fixing mechanism also includes a connecting plate and a limiting mechanism. A groove is formed on the supporting plate, and the connecting plate is rotatably mounted within the groove via a rotating shaft. The connecting plate is hinged to two arc-shaped plates via two hinge plates and two cylindrical blocks, respectively. The limiting mechanism is used to limit the movement of the two arc-shaped plates. By pushing one arc-shaped plate, the connecting plate rotates, thereby causing the other arc-shaped plate to rotate, thus facilitating the simultaneous movement of the two arc-shaped plates to clamp the cable.

[0010] Furthermore, the limiting mechanism includes a plug-in block, which is fixedly mounted on an arc-shaped plate, and a slot is provided on another arc-shaped plate, through which the plug-in block is plugged into the slot.

[0011] Furthermore, the limiting mechanism also includes a locking pin, which is connected to the insertion block via a limiting spring. The locking pin and the insertion block are slidably connected, and a circular hole is provided on the inner side of the slot, with the locking pin engaging with the circular hole. Through the engaging effect of the locking pin and the circular hole, the two curved plates can maintain a stable clamping state, preventing them from separating.

[0012] Furthermore, the mounting mechanism includes multiple fixing blocks, all of which are fixedly mounted on the mounting plate. Multiple through slots are provided on the side wing plate, and the fixing blocks are respectively inserted into these slots. The multiple fixing blocks and through slots effectively secure the two protective shells, preventing them from detaching if the spring on one fixing block fails or is compressed.

[0013] Furthermore, the installation mechanism also includes a wedge, which is connected to the fixing block by a spring and is slidably connected to the fixing block. The wedge also engages with the side wing plate. This engagement between the wedge and the side wing plate facilitates quick and easy installation of the two protective shells, improving installation efficiency.

[0014] The beneficial effects of this utility model are as follows: This gel-type protective device for cable terminals used in cable joints, through the setting of a fixing mechanism and a limiting mechanism, enables two arc-shaped plates to fix the cable inside the protective shell, ensuring that the cable joint is always kept in the center position inside the protective shell, thereby improving the use and protective effect of the gel-type protective device. In addition, through the setting of an installation mechanism, the two arc-shaped plates can be installed quickly, and the multiple fixing blocks and wedges set at the same time make it difficult for the two arc-shaped plates to separate and fall off, thereby improving the working efficiency and use effect of the gel-type protective device.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent.

[0027] Reference Figures 1 to 3 The gel-type protective device for cable joints and cable terminals shown includes two protective shells 1, an installation mechanism 4, and a fixing mechanism 5. The two protective shells 1 are connected by an installation plate 2 and a side wing plate 3. By connecting the two protective shells 1, the cable joint can be surrounded inside the protective shell 1, providing protection for the cable joint. The installation mechanism 4 is used to limit the installation plate 2 and the side wing plate 3, so that the two protective shells 1 are always fixedly connected together, preventing them from falling off or separating. The fixing mechanism 5 is fixedly installed inside one of the protective shells 1. The fixing mechanism 5 is used to fix the cable, so that the cable joint is always in the middle position inside the protective shell 1, which allows the gel to completely wrap and protect the cable joint. The top of the other protective shell 1 has an injection hole 6, which is used to inject gel into the protective shell 1. At the same time, the injection hole 6 is sealed with a plug after the gel is injected.

[0028] Reference Figure 2 and Figure 4 The fixing mechanism 5 includes a support plate 51 and two arc-shaped plates 52. The fixing mechanism 5 is symmetrically distributed in two sets, which respectively fix the two ends of the cable located inside the protective shell 1. The support plate 51 is fixedly installed on the inner side of one of the protective shells 1. The two arc-shaped plates 52 are slidably installed on the support plate 51 through two guide rods 53. Through the movement effect of the two arc-shaped plates 52, the two arc-shaped plates 52 can clamp and fix the cable, or release the clamping effect.

[0029] Reference Figure 4 and Figure 5 The fixing mechanism 5 also includes a connecting plate 55 and a limiting mechanism 59. The support plate 51 has a groove 54, which is used to avoid interference with the connecting plate 55. The connecting plate 55 is rotatably installed in the groove 54 through a rotating shaft 56. The connecting plate 55 is hinged to the two arc plates 52 through two hinge plates 57 and two cylindrical blocks 58 respectively. The two hinge plates 57 are distributed at both ends of the connecting plate 55. Through the rotation effect of the connecting plate 55, the two hinge plates 57 and the two cylindrical blocks 58 can be moved simultaneously, thereby causing the two arc plates 52 to move closer or further away from each other, which facilitates the clamping or releasing of the cable. The limiting mechanism 59 is used to limit the two arc plates 52, so that the two arc plates 52 can always maintain the clamped state and prevent the two arc plates 52 from separating.

[0030] Reference Figure 6 and Figure 7The limiting mechanism 59 includes a plug block 591, which is fixedly installed on an arc plate 52. The size of the plug block 591 corresponds to the size of the slot 594. Another arc plate 52 has a slot 594. The plug block 591 is plugged into the slot 594. Through the movement of the two arc plates 52, the plug block 591 and the slot 594 can be moved respectively, thereby enabling the plug block 591 to be plugged into or unplugged from the slot 594. The limiting mechanism 59 also includes a locking post 593, which is connected to the insertion block 591 by a limiting spring 592. The locking post 593 and the insertion block 591 are slidably connected. Through the elastic force of the limiting spring 592, the locking post 593 is always locked with the round hole 595 when no external force is applied. The inner side of the slot 594 has a round hole 595, and the locking post 593 is locked with the round hole 595. Through the locking effect of the locking post 593 and the round hole 595, the two arc plates 52 can be limited, so that the two arc plates 52 remain fixed.

[0031] Reference Figure 3 and Figure 8 The installation mechanism 4 includes multiple fixing blocks 41, which are all fixedly installed on the mounting plate 2. The size and number of the fixing blocks 41 correspond to the through slots 44. Multiple through slots 44 are provided on the side wing plate 3. The multiple fixing blocks 41 are respectively inserted into the multiple through slots 44. By inserting the multiple fixing blocks 41 into the multiple through slots 44, the two protective shells 1 can be positioned and fixed. At the same time, when the spring 43 set on one fixing block 41 fails or is squeezed, the other fixing blocks 41 can still play a limiting role, thereby preventing the two protective shells 1 from falling off and separating.

[0032] Reference Figure 1 and Figure 8 The installation mechanism 4 also includes a wedge 42, which is connected to the fixing block 41 by a spring 43 and is slidably connected to the fixing block 41. Through the elastic force of the spring 43, the wedge 42 is always engaged with the side wing plate 3 without external force. The wedge 42 and the side wing plate 3 are engaged, which limits the two protective shells 1 and keeps them fixed together.

[0033] Reference Figures 1 to 8This gel-type protective device for cable terminals used in cable joints, through its fixing and limiting mechanisms, enables two arc-shaped plates to fix the cable within the protective shell, ensuring that the cable joint remains in the center of the protective shell. This improves the effectiveness and protective performance of the gel-type protective device. In addition, the installation mechanism allows for quick installation of the two arc-shaped plates, while the multiple fixing blocks and wedges prevent the two arc-shaped plates from separating or falling off, further enhancing the working efficiency and effectiveness of the gel-type protective device.
