Description

Technical Field

[0001] The utility model relates to the technical field of cable connection, in particular to a quick-insertion cable docking structure. Background Art

[0002] A cable is an electrical energy or signal transmission device, made of one or more mutually insulated conductors and an outer insulating protective layer, and has the characteristics of internal power conduction and external insulation. It is usually a rope-like cable made of several or several groups of wires (at least two wires in each group). Each group of wires is insulated from each other and often twisted around a center, and the entire outer surface is covered with a highly insulating covering layer. When laying cables, two cables need to be connected for locations with insufficient length or special locations. The existing connection method is usually to wrap the copper cores of the two cables around each other and then use tape to wrap and bond them. This method of connection takes a long time to operate, which affects the speed of cable laying, and the copper core is easy to hurt fingers. On the other hand, the connection strength is low, and the tape connection is very easy to break, affecting normal use. Utility Model Content

[0027] Example

[0028] As mentioned in the background technology, during the cable laying process, cables that are not long enough or need to be connected for use in special locations are used. When connecting existing cables, the copper cores 6 of different cables are usually wound around each other, and then the wound positions are bonded with tape. However, this method has many disadvantages. On the one hand, the connection speed is slow, and the copper core 6 is sharp and can easily hurt fingers. On the other hand, there is a risk of breakage over a long period of time. Therefore, the inventors designed a new docking structure in the process of specific practice to solve the above problems, which will be explained in detail below with reference to the drawings.

[0029] This embodiment provides a quick-plug cable docking structure. Figure 1 The docking structure is installed between the first cable 1 and the second cable 2. The first connecting sleeve 3 and the second connecting sleeve 4 are respectively provided at the ends where the first cable 1 and the second cable 2 are connected. The first connecting sleeve 3 and the second connecting sleeve 4 are both flange-shaped and installed with the corresponding external surfaces of the first cable 1 and the second cable 2.

[0030] Based on the above structure, combined with Figure 3In order to facilitate the connection of the copper core 6 of the first cable 1 and the second cable 2, a mounting hole 5 for installing the cable end is opened on the side opposite to the first connecting sleeve 3 and the second connecting sleeve 4. The mounting hole 5 is used to install the ends of the first cable 1 and the second cable 2. Secondly, a plurality of connecting holes 7 for the copper core 6 to pass through are opened in the mounting hole 5. The number of the connecting holes 7 should be consistent with the arrangement position and number of the copper core 6 in the cable. The first connecting sleeve 3 and the second connecting sleeve 4 are arranged horizontally and opened in parallel with the cables. When the cables are connected, the copper cores 6 of the first cable 1 and the second cable 2 enter the corresponding connecting holes 7 respectively. In order to facilitate the fixing of the copper core 6, the copper of the first cable 1 The exposed length of the core 6 should be greater than the exposed length of the copper core 6 of the second cable 2, so that the copper core 6 of the first cable 1 can enter the connecting hole 7 of the second connecting sleeve 4, and a plurality of threaded holes 14 are opened on the outside of the second connecting sleeve 4, and are connected with the connecting hole 7. The threaded holes 14 are entered by locking bolts 15 to fix the connection between the copper core 6 of the first cable 1 and the second cable 2, and in order to improve stability, the number of the threaded holes 14 is not less than the number of connecting holes 7. In this embodiment, the number of threaded holes 14 is consistent with the number of connecting holes 7, and they are respectively connected to the corresponding connecting holes 7. The locking bolts 15 enter the connecting holes 7 to fix the connection between the copper cores 6 of different cables.

[0031] In order to insulate the locking bolt 15 , an insulating end cover 16 is provided outside the threaded hole 14 . The locking bolt 15 in the threaded hole 14 can also be protected by providing the end cover.

[0032] Based on the above structure, combined with Figure 2 and Figure 3 The first connecting sleeve 3 is provided with a plurality of positioning grooves 12 on one side close to the second connecting sleeve 4, and the second connecting sleeve 4 is correspondingly provided with a plurality of positioning strips 13. When the first connecting sleeve 3 is connected to the second connecting sleeve 4, the positioning strips 13 are directly matched with the positioning grooves 12 one by one, so that the positioning strips 13 enter the positioning grooves 12, thereby completing the preliminary positioning of the first connecting sleeve 3 and the second connecting sleeve 4.

[0033] In order to fix the first connecting sleeve 3 and the second connecting sleeve 4, multiple groups of locking structures 8 are movably arranged on the outside of the first connecting sleeve 3, and the second connecting sleeve 4 is correspondingly provided with a locking groove 9 adapted to the locking end of the locking structure 8. The locking structure 8 is installed on the outside of the flange position of the first connecting sleeve 3, and the locking groove 9 is correspondingly opened on the outside of the flange of the second connecting sleeve 4. In this embodiment, in order to improve the stability of fixing the first connecting sleeve 3 and the second connecting sleeve 4, a total of four groups of locking structures 8 are arranged, and they are evenly distributed along the circumference of the first connecting sleeve 3, and four groups of corresponding locking grooves 9 are arranged.

[0034] In this embodiment, the specific structure of the locking structure 8 is: Figure 2 , including a base 81 hinged to the first connecting sleeve 3, connected by a hinge, and a rotating column 82 is rotatably arranged on the base 81, and the rotating column 82 can rotate with the base 81 to be parallel to the cable. When parallel to the cable, the rotating column 82 is located on the outside of the first connecting sleeve 3, and at this position, the locking end can move along the rotating column 82 into the locking groove 9 and can be fixed in the locking groove 9, wherein, in order to realize the movement of the locking end along the rotating column 82, a partial external screw is arranged on the outside of the rotating column 82 The sleeve 84 is threadedly connected to the external thread 83 on the outer side of the rotating column 82. In order to cooperate with the locking groove 9, a locking block 85 adapted to the locking groove 9 is installed on the outer edge of the sleeve 84. When the rotating column 82 rotates, a part of the locking block 85 enters the edge of the locking groove 9, and the locking groove 9 limits the locking block 85. Through the action of the thread, the sleeve 84 moves along the rotating column 82, and then the locking block 85 moves along with it until it is completely moved into the locking groove 9.

[0035] On the basis of the above structure, in order to ensure the degree of adaptation between the locking block 85 and the locking groove 9, the width of the locking block 85 is consistent with the depth of the locking groove 9, that is, the dimensions of the two along the cable direction are consistent, ensuring that the locking block 85 can fully enter the locking groove 9 to complete the fixation of the first connecting sleeve 3 and the second connecting sleeve 4.

[0036] In order to improve the stability and locking effect of the locking block 85 after locking, a limiting hole 10 is opened in the locking groove 9, and the opening direction of the limiting hole 10 is consistent with the moving direction of the locking block 85 during locking. A limiting column 11 that can be inserted into the limiting hole 10 is provided on one side of the locking block 85. When the locking block 85 fully enters the locking groove 9, the limiting column 11 can fully enter the limiting hole 10 to complete further limiting of the locking block 85.
