Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to a cable connecting device. Background Art

[0002] Cable connectors usually refer to tubular items used to connect two cables. Cable connectors have good protection and insulation properties to prevent cables from leakage or erosion by the external environment.

[0003] The traditional way to connect cables is to use a cable connector to connect two cables, then drag the cable connector so that the middle of the cable connector is located at the connection point of the two cables to achieve the connection. Before connecting the cables, the cable connector needs to be pre-expanded in the factory or expanded on-site before installation, and support strips are filled inside the cable connector to facilitate dragging the cable connector during installation. However, the resilience of the expanded cable connector is poor, and the clamping force between the cable connector and the cable is insufficient, which may cause cable breakdown. Moreover, when dragging the cable connector, the support strip is prone to breakage, and the cable shielding layer on the surface of the cable is prone to decarbonization due to repeated friction with the cable connector, which causes problems with the quality of cable installation.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Combine the following Figure 1-Figure 2 , through specific embodiments and application scenarios, a cable connection device provided by an embodiment of the utility model is described in detail.

[0031] like Figure 1 and Figure 2As shown, the utility model provides a cable connection device, including: a cable connector 1, a male socket 2, a female socket 3 and a locking member 4. The male socket 2 is used to be electrically connected to the first cable 100, and the female socket 3 is used to be electrically connected to the second cable 200. The locking member 4 is provided at the connection between the male socket 2 and the female socket 3 to lock the male socket 2 and the female socket 3. The cable connector 1 is sleeved on the outside of the male socket 2 and the female socket 3, and the two ends of the cable connector 1 are used to be flush with the installation positioning lines of the first cable 100 and the second cable 200 respectively.

[0032] It is understood that the cable connector 1 generally refers to a tubular object used to connect two cables. It is usually made of soft and durable materials, such as rubber, plastic or silicone. The cable connector 1 acts as a protective layer to prevent the cable from being damaged by the external environment, such as water, dust, chemicals, etc. In addition, the cable connector 1 has insulation properties, which can block current to a certain extent, preventing the cable from being damaged or causing danger due to short circuit or leakage.

[0033] The traditional way to connect two cables is to use a cable connector to connect the two cables, and then drag the cable connector so that the middle of the cable connector is located at the connection point of the two cables to achieve the connection. Before crimping, the cable connector needs to be pre-expanded in the factory or expanded on-site before installation, and a support bar is filled inside the cable connector. The inner diameter of the support bar is larger than the outer diameter of the cable to facilitate dragging the cable during installation. However, the elasticity of the expanded cable connector is poor, and the clamping force between the cable connector and the cable is insufficient, which may cause cable breakdown. Moreover, in this method of first putting the cable connector on a cable, connecting the two cables, and then pushing and pulling the cable connector to the middle position, the support bar is prone to breakage, and the cable shielding layer on the surface of the cable is decarbonized due to repeated friction with the cable connector, which causes problems with the quality of cable installation.

[0034] The cable connection device provided by the utility model can realize effective electrical connection of two cables without frequent dragging of the cable connector, thereby reducing installation quality risks. Figure 1 As shown, the male socket 2 and the female socket 3 are adapted. The male socket 2 is used to be electrically connected to the first cable 100, and the female socket 3 is used to be electrically connected to the second cable 200. The male socket 2 and the female socket 3 can be electrically connected to the first cable 100 and the second cable 200 respectively by crimping.

[0035] like Figure 1 As shown, the locking member 4 is disposed between the male socket 2 and the female socket 3, and is used to automatically lock the male socket 2 and the female socket 3, thereby achieving a stable connection between the first cable 100 and the second cable 200. Furthermore, the cable connector 1 is sleeved on the outside of the male socket 2 and the female socket 3, so as to further protect the first cable 100, the male socket 2, the female socket 3 and the second cable 200, and increase the stability of the connection between the first cable 100 and the second cable 200.

[0036] During assembly, first electrically connect the male socket 2 and the first cable 100, and electrically connect the female socket 3 and the second cable 200; then, one end of the cable connector 1 is sleeved on the male socket 2 and the first cable 100, and the end of the cable connector 1 is flush with the installation positioning line of the first cable 100, ensuring the connection length of the first cable 100 and the cable connector 1; then, insert the female socket 3 from the other end of the cable connector 1 into the interior of the cable connector 1, and the other end of the cable connector 1 is flush with the installation positioning line of the second cable 200, ensuring the connection length of the second cable 200 and the cable connector 1; when the female socket 3 is inserted to a certain depth and contacts the male socket 2, the locking member 4 automatically locks the female socket 3 on the male socket 2.

[0037] Of course, one end of the cable connector 1 can be first sleeved on the female socket 3 and the second cable 200, and then the male socket 2 can be inserted into the interior of the cable connector 1 from the other end, so that the locking piece 4 locks the male socket 2 on the female socket 3, thereby realizing the electrical connection between the first cable 100 and the second cable 200.

[0038] The utility model provides a cable connection device, wherein a male socket 2 is used for electrically connecting to a first cable 100, and a female socket 3 is used for electrically connecting to a second cable 200. A locking member 4 is arranged at the connection between the male socket 2 and the female socket 3, and can automatically lock the male socket 2 and the female socket 3, thereby ensuring the stability of the electrical connection between the first cable 100 and the second cable 200. A cable connector 1 is sleeved on the outside of the male socket 2 and the female socket 3, and two ends of the cable connector 1 are used to be flush with the installation positioning lines of the first cable 100 and the second cable 200, respectively, so as to form protection for the male socket 2 and the female socket 3, thereby ensuring the clamping force of the cable connector 1 on the first cable 100 and the second cable 200. The utility model only needs to sleeve one end of the cable connector 1 until it is flush with the installation positioning line of the first cable 100, and then insert the female socket 3 from the other end of the cable connector 1 until it contacts the male socket 2. The other end of the cable connector 1 is flush with the installation positioning line of the second cable 200. The locking member 4 automatically locks the male socket 2 and the female socket 3. There is no need to expand and drag the cable connector 1. The cable connector 1 is not easily damaged, thereby improving the installation quality of the cable.

[0039] Specifically, Figure 2 As shown, the female seat 3 is provided with a connecting groove 31 . The male seat 2 is inserted into the connecting groove 31 , and the male seat 2 has a limiting portion 21 , which abuts against the notch end of the connecting groove 31 , and the locking member 4 is provided in the connecting groove 31 .

[0040] It is understandable that the female seat 3 is provided with a connection groove 31, and the notch of the connection groove 31 faces the male seat 2. Correspondingly, the end of the male seat 2 close to the female seat 3 is convex. The cross-sectional dimension of the end of the male seat 2 is smaller than the maximum outer diameter dimension of the male seat 2, so that a limit portion 21 is formed at the place where its size changes. The male seat 2 is inserted into the female seat 3, and the limit portion 21 and the notch end of the connection groove 31 are in conflict to ensure the stability of the connection between the male seat 2 and the female seat 3.

[0041] In this embodiment, the locking member 4 is disposed in the connecting groove 31, and is used to lock the portion of the male socket 2 inserted in the connecting groove 31 in the connecting groove 31, thereby achieving effective electrical connection between the male socket 2 and the female socket 3, and ensuring the stability and accuracy of the connection between the first cable 100 and the second cable 200.

[0042] Furthermore, in some embodiments, Figure 2 As shown, the female socket 3 has a first conductive column 32 . The first conductive column 32 is disposed in the connection slot 31 , the male socket 2 has a second conductive column 22 , and the locking member 4 is used to lock the first conductive column 32 and the second conductive column 22 , so that the first conductive column 32 and the second conductive column 22 abut against each other.

[0043] It is understandable that the first conductive post 32 is protruded from the bottom of the connecting groove 31. The axial direction of the first conductive post 32 coincides with the axial direction of the second cable 200. Correspondingly, the male socket 2 is provided with a second conductive post 22 adapted to the first conductive post 32. The second conductive post 22 is protruded from the end surface of the male socket 2. The locking member 4 is provided in the connecting groove 31 and is located at the connection between the first conductive post 32 and the second conductive post 22, so that the end surfaces of the first conductive post 32 and the second conductive post 22 are closely in contact, thereby realizing normal power supply of the first cable 100 and the second cable 200.

[0044] In this embodiment, the first conductive pillar 32 and the second conductive pillar 22 are in close contact with each other. At the same time, the limiting portion 21 and the notch end of the connecting groove 31 are in contact with each other, which can increase the stability of the connection between the male socket 2 and the female socket 3 .

[0045] In some embodiments, Figure 2 As shown, the locking member 4 includes an elastic tube 41 and a plurality of snap rings 42. One end of the snap ring 42 is connected to the groove wall of the connecting groove 31, and the other end is connected to the outer wall of the elastic tube 41.

[0046] The elastic tube 41 is provided with a slot 401. The first conductive column 32 and the second conductive column 22 both have end caps, and the first conductive column 32 and the second conductive column 22 are both inserted into the elastic tube 41. The end caps are clamped in the slot 401, and the ends of the two end caps are abutted.

[0047] It is understandable that the elastic tube 41 can be made of an insulating material with strong deformation ability such as elastic rubber or silicone. The elastic tube 41 is provided with a slot 401. The slot 401 is used to insert the first conductive column 32 and the second conductive column 22.

[0048] The first conductive column 32 and the second conductive column 22 both have end caps. Figure 2 As shown, the two ends of the slot 401 are narrow and the middle is wide. The shape and size of the slot 401 are adapted to the overall structure formed by the first conductive column 32 and the second conductive column 22. The first conductive column 32 and the second conductive column 22 are symmetrically arranged along the radial direction of the elastic tube 41.

[0049] like Figure 2 As shown, the locking member 4 further includes a plurality of snap springs 42. The plurality of snap springs 42 are arranged at intervals along the circumference of the elastic tube 41. One end of the snap spring 42 is connected to the outer wall of the elastic tube 41, and the other end is connected to the groove wall of the connecting groove 31.

[0050] During assembly, the first conductive column 32 is inserted from one end of the slot 401. When the first conductive column 32 just enters the slot 401, the end cap squeezes the spring 42, causing the elastic tube 41 to expand, so that the first conductive column 32 can be smoothly inserted into the slot 401. Then, the second conductive column 22 is inserted from the other end of the slot 401. When the second conductive column 22 just enters the slot 401, the spring 42 is squeezed, causing the elastic tube 41 to expand, so that the second conductive column 22 can be smoothly inserted into the slot 401, and further the end cap of the first conductive column 32 and the end cap of the second conductive column 22 are tightly abutted, thereby realizing the transmission of current between the male socket 2 and the female socket 3.

[0051] like Figure 2 As shown, the elastic tube 41 has a guiding slope 402 for guiding the first conductive column 32 and / or the second conductive column 22 to be inserted into the slot 401. The two ends of the slot 401 have guiding slopes 402. The aperture of the slot 401 at the guiding slope 402 is larger to facilitate the insertion of the first conductive column 32 and / or the second conductive column 22 into the slot 401.

[0052] Specifically, Figure 2 As shown, the outer wall of the elastic tube 41 is provided with a plurality of mounting grooves 403. The plurality of mounting grooves 403 are respectively provided at both ends of the clamping groove 401, and the ends of the plurality of clamping springs 42 are fixed to the groove walls of the plurality of mounting grooves 403 in a one-to-one correspondence.

[0053] It is understandable that the outer wall of the elastic tube 41 is provided with a plurality of mounting grooves 403. One end of the plurality of clips 42 is fixed to the groove wall of the mounting groove 403 in a one-to-one correspondence, and the other ends of the plurality of clips 42 are respectively installed on the groove wall of the connecting groove 31.

[0054] Preferably, the plurality of mounting grooves 403 are spaced apart along the circumference of the elastic tube 41 and are disposed at both ends of the slot 401. On the one hand, the plurality of retaining springs 42 are spaced apart along the radial direction of the elastic tube 41, so that the elastic tube 41 can be flexibly extended and contracted, which is conducive to the rapid expansion of the elastic tube 41; on the other hand, the retaining springs 42 are disposed at the ends of the slot 401, which is conducive to the rapid expansion of the elastic tube 41 when the end cap of the first conductive column 32 or the second conductive column 22 is just inserted into the slot 401. Furthermore, when the end cap is inserted into the middle of the slot 401, the retaining spring 42 automatically resets, restoring the size of the end of the slot 401 to the original size, thereby further locking the first conductive column 32 and / or the second conductive column 22 by the retaining spring 42 and the elastic tube 41.

[0055] In some embodiments, the elastic tube 41 includes a first elastic block 411 and a second elastic block 412. The first elastic block 411 and the second elastic block 412 both have through holes, and the first elastic block 411 and the second elastic block 412 are symmetrically connected along the radial direction of the elastic tube 41 to form a card slot 401.

[0056] It is understandable that the first elastic block 411 and the second elastic block 412 are annular. The first elastic block 411 and the second elastic block 412 have the same structure. The first elastic block 411 and the second elastic block 412 are symmetrically connected along the radial direction of the elastic tube 41. The through holes of the first elastic block 411 and the second elastic block 412 are connected to form the card slot 401.

[0057] Taking the first elastic block 411 as an example, the first elastic block 411 includes a plurality of sub-blocks. The plurality of sub-blocks are fixedly connected in sequence along the radial direction of the first elastic block 411. In some embodiments, the outer wall of each sub-block is connected to a clamping spring 42.

[0058] In some embodiments, Figure 2 As shown, the male socket 2 is provided with a first groove 23 for crimping the conductive end of the first cable 100 . The female socket 3 is provided with a second groove 33 for crimping the conductive end of the second cable 200 .

[0059] It is understood that the notch of the first groove 23 faces the first cable 100. The shape and size of the first groove 23 are adapted to the conductive end of the first cable 100. The notch of the second groove 33 faces the first cable 100. The shape and size of the second groove 33 are adapted to the conductive end of the second cable 200.

[0060] When the conductive terminal of the first cable 100 is inserted into the first groove 23 , the axial direction of the conductive terminal of the first cable 100 is aligned with the extending direction of the first groove 23 , and then the first groove 23 is crimped onto the conductive terminal of the first cable 100 .

[0061] When the conductive end of the second cable 200 is inserted into the second groove 33 , the axial direction of the conductive end of the second cable 200 is aligned with the extension direction of the second groove 33 , and then the second groove 33 is crimped onto the conductive end of the second cable 200 .

[0062] By respectively setting the first groove 23 and the second groove 33 on the male socket 2 and the female socket 3, the conductive ends of the first cable 100 and the second cable 200 can be conveniently crimped into the corresponding grooves, thereby realizing electrical connection between the male socket 2 and the female socket 3 and the first cable 100 and the second cable 200 respectively.

[0063] Specifically, Figure 1 As shown, the cable connector 1 includes a first semiconductive part 11, a second semiconductive part 12 and an insulating part 13 which are integrally connected. The first semiconductive part 11 is located inside the insulating part 13 and in the connection area between the male socket 2 and the female socket 3, and the second semiconductive part 12 is located at both ends of the insulating part 13.

[0064] It is understandable that the first semiconductive part 11 and the insulating part 13 are both cylindrical. The first semiconductive part 11 is connected to the insulating part 13 and is located on the inner side of the cable connector 1. The first semiconductive part 11 and the second semiconductive part 12 both have semiconductive properties. The first semiconductive part 11 is sleeved on the outside of the male socket 2 and the female socket 3 to evenly distribute the electric field at the connection between the male socket 2 and the female socket 3, thereby ensuring the conduction performance of the current between the first cable 100 and the second cable 200.

[0065] Furthermore, if Figure 1 As shown, the second semiconductive part 12 is connected to the first semiconductive part 11 and is located at both ends of the insulating part 13, so that the second semiconductive part 12 evenly distributes the electric field at the cable shielding layer of the first cable 100 and the second cable 200, ensuring the stability of the current transmitted between the first cable 100 and the second cable 200.

[0066] The insulating portion 13 is located between the first semiconductive portion 11 and the second semiconductive portion 12 and is used to isolate and protect the male socket 2 and the female socket 3 to prevent leakage or short circuit.

[0067] In this embodiment, the cable connector 1 is composed of a first semiconductive part 11, a second semiconductive part 12 and an insulating part 13 which are integrally connected, thereby achieving insulation protection for the male socket 2 and the female socket 3 and ensuring the conduction performance of the current between the male socket 2 and the female socket 3.

[0068] Optionally, the first semiconductive portion 11 and the second semiconductive portion 12 are semiconductive silicone rubber pieces, and the insulating portion 13 is an insulating rubber piece or an insulating silicone piece.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
