Description

Technical Field

[0001] The utility model relates to the technical field of connection auxiliary devices, in particular to an auxiliary device for cable connection. Background Art

[0002] The cable has a certain length, and thus has a certain gravity. Due to the different external natural environments where the cables are installed, there are also situations such as wind blowing. Therefore, the connection between the cables is often in danger of breaking. In order to ensure the stability of the cable connection, auxiliary devices are often used in the prior art, such as the patent with publication number CN109004617A, which discloses a power grid cable connection auxiliary device. Specifically, it uses a pair of pressure rings to reinforce the connection of a pair of cables, wherein the pressure rings are connected by long threaded rods, and the pressure rings are pushed to adjust the distance by a stopper;

[0003] However, using a pair of compression rings to connect a pair of cables will increase the gravity at the connection. Since the cables have a certain flexibility, the joints will not only not be reinforced, but the interfaces will also be prone to breakage.

[0004] Based on the above description, there is an urgent need for an auxiliary device for cable connection that can ensure that the interface is not prone to breakage and is stable. Utility Model Content

DETAILED DESCRIPTION

[0021] Example 1

[0022] See also Figures 1 to 3 , the utility model provides the following technical solutions: an auxiliary device for cable connection, suitable for cable connection situations.

[0023] Specifically, Figure 1 and Figure 2 As shown, an auxiliary device for cable connection includes a pressure ring assembly 1 and a connection assembly 2; the connection assembly 2 includes a first cylinder 21 and a second cylinder 22; one end of the second cylinder 22 passes through the first cylinder 21 and is connected to the first cylinder 21 through a buffer assembly 3; one end of the first cylinder 21 away from the buffer assembly 3 and one end of the second cylinder 22 away from the buffer assembly 3 are connected through the pressure ring assembly 1.

[0024] The specific implementation process is: the first cylinder 21 is sleeved on the connection end of the first cable 4, and the second cylinder 22 is sleeved on the connection end of the second cable 5. The connection between the first cable 4 and the second cable 5 is achieved by inserting one end of the second cylinder 22 into the first cylinder 21 and clamping the first cylinder 21 and the second cylinder 22 through the pressure ring assembly 1. Furthermore, on the basis of adopting the first cylinder 21 and the second cylinder 22, a buffer assembly 3 is set to ensure that the connection of a pair of cables is not easily broken due to gravity factors, and it can also ensure that when there are adverse factors such as wind in the external environment, the cable connection is buffered by the buffer assembly 3 and is not easily broken due to shaking, thereby fully ensuring the stability of the cable connection.

[0025] In this embodiment, since the inner diameter of the first cylinder 21 is larger than that of the second cylinder 22, further fillers can be placed between the first cylinder 21 and the first cable 4. Specifically, a silicone tube can be installed at the connection of the first cable 4 to connect the first cylinder 21 through the silicone tube. An annular baffle is further inverted at the end of the first cylinder 21 away from the second cylinder 22 to ensure that the filler does not fall. In addition, the pressure ring assembly 1 is an existing structure, including a pair of pressure rings and a screw connecting the pair of pressure rings, and the first cylinder 21 and the second cylinder 22 are connected by a pair of pressure rings.

[0026] Specifically, Figure 2 and Figure 3As shown, the buffer assembly 3 includes an elastic snap ring 31, a first annular baffle plate 32 and a buffer member 33; the elastic snap ring 31 is arranged at one end of the second cylinder 22 that passes through the first cylinder 21; the first annular baffle plate 32 and the buffer member 33 are relatively arranged at one end of the first cylinder 21 close to the first cylinder 21; a snap gap is left between the first annular baffle plate 32 and the buffer member 33.

[0027] In this embodiment, the second cylinder 22 is clamped into the first annular baffle 32 and the buffer member 33 by the elastic clamping ring 31, leaving a clamping gap, so that a pair of cables can be connected, and when the cable connection point shakes back and forth, the buffer member 33 can achieve a buffering effect, thereby reducing the risk of breakage at the cable connection point.

[0028] Specifically, Figure 3 As shown, the buffer member 33 includes a buffer ring plate 331 and a plurality of spring columns 332; a second annular baffle plate 211 is provided at one end of the first cylinder 21 close to the second cylinder 22; the buffer ring plate 331 is connected to the second annular baffle plate 211 through the spring column 332. The buffer ring plate 331 is provided with a plurality of first limiting grooves at intervals; the elastic snap ring 31 is provided with a plurality of first protrusions 311 embedded in the first limiting grooves. The first protrusion 311 is a hemispherical protrusion; the first limiting groove is a hemispherical groove. A second limiting groove is provided on one side of the first annular baffle plate 32 close to the buffer ring plate 331; the elastic snap ring 31 is provided with a plurality of second protrusions 312 embedded in the second limiting grooves.

[0029] In this embodiment, the elastic snap ring 31 is inserted into the first annular baffle plate 32 and the buffer member 33 to leave a gap, and the first protrusion 311 is further inserted into the first limiting groove, and the second protrusion 312 is inserted into the second limiting groove, thereby achieving the connection between the first cable 4 and the second cable 5 while ensuring the stability of the connection; wherein, the first protrusion 311 and the second protrusion 312 are both hemispherical protrusions, and the plate surface height of the first annular baffle plate 32 is greater than the buffer ring plate 331, thereby ensuring that the first protrusion 311 and the second protrusion 312 can both be embedded in the corresponding limiting grooves.
