Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a low-voltage power cable that is easy to quickly connect. Background Technology

[0002] Low-voltage power cables are widely used in residential electricity, commercial facilities, and small industrial equipment. During the laying of low-voltage power cables, it is often necessary to connect them. However, power needs to be cut off when connecting low-voltage power cables. In order to shorten the power outage time, workers usually use low-voltage power cables that are easy to connect quickly. Existing low-voltage power cables that are easy to connect quickly usually consist of a cable body and a connector.

[0003] For example, utility model application CN202423099745.6 discloses an energy storage cable that facilitates rapid connection. Specifically, it includes a first cable and a second cable, with a connection assembly between them. The connection assembly includes a lower protective shell, with first fixing blocks connected to both front surfaces of the lower protective shell. An upper protective shell is rotatably connected to the rear end of the lower protective shell, and second fixing blocks are connected to both front surfaces of the upper protective shell. Bolts are inserted into the interior of both sets of second fixing blocks, with nuts threaded to the bottom of the bolts. A conductive block is connected to the center of the surface of the lower protective shell. In this utility model, when connecting the first and second cables, the lower and upper protective shells can be used for connection and fixation. The internal conductive blocks have conductive properties, enabling rapid cable connection and avoiding the problem of cable disconnection that easily occurs with crimping or winding connections.

[0004] However, for traditional low-voltage power cables that are easy to connect quickly, after connecting them with a butt joint, clamps or bolts are usually used to fix the butt joint to prevent it from loosening. This means that after the connection is completed, the workers still need to use tools such as wrenches and screwdrivers to fix the butt joint a second time. The operation is cumbersome, especially in the process of large-scale connection, which makes the labor intensity of the workers high and the use inconvenient. Utility Model Content

[0005] In view of this, the present invention provides a low-voltage power cable that facilitates quick connection. It has a limiting wedge and a locking wedge that can automatically fix the connection after it is completed. As the first pair of connectors is inserted into the second pair of connectors, the fixing block is inserted into the fixing slot, and the limiting wedge is locked on the outside of the second pair of connectors, thus fixing the connected first and second pairs of connectors. During the reset process of the limiting wedge, the locking wedge is squeezed. After the limiting wedge is fully reset, the locking wedge is aligned with the groove reserved on the limiting wedge. At this time, the limiting wedge will reset with the rebound of the locking spring and insert into the groove reserved on the limiting wedge, so that the locking wedge and the limiting wedge interlock.

[0012] Beneficial effects When connecting low-voltage power cables, this application involves inserting the first pair of connectors into the second pair of connectors. As the first pair of connectors is inserted, a fixing block is inserted into a fixing slot. During the insertion of the fixing block into the fixing slot, the fixing slot presses against the limiting wedge. Subsequently, through a series of transmissions, the limiting wedge is locked onto the outside of the second pair of connectors, thus fixing the connected first and second pairs of connectors. During the resetting process of the limiting wedge, a series of transmissions cause the limiting wedge to insert into its pre-reserved groove, interlocking the locking wedge and the limiting wedge. The reverse tooth-shaped anti-slip texture enhances the anti-loosening effect between the locking wedge and the limiting wedge. The operation is simple and quick, facilitating workers to quickly connect low-voltage power cables, reducing the labor intensity of workers, and effectively improving the practicality of low-voltage power cables that are easy to connect quickly, making them more convenient to use.

[0028] Each of the four sets of limiting wedges 105 has a locking wedge 107 inserted into it; the four sets of locking wedges 107 are slidably connected in the first pair of connectors 102; the four sets of locking wedges 107 are arranged in a ring array; a locking spring 108 is fixedly connected to the outside of each of the four sets of locking wedges 107; the ends of the four sets of locking springs 108 are fixedly connected in the first pair of connectors 102; the meshing surfaces of the four sets of locking wedges 107 and the four sets of limiting wedges 105 are provided with reverse tooth-shaped anti-slip textures.

[0029] Each of the four sets of limiting wedges 105 is slidably connected to a set of control push seats 109; each of the four sets of control push seats 109 is fixedly connected to a set of connecting springs 110; the ends of the four sets of connecting springs 110 are respectively fixedly connected to the four sets of limiting wedges 105.

[0030] Multiple sets of auxiliary springs 115 are fixedly connected to the outside of the connecting collar 114 in a circular array; the ends of the multiple sets of auxiliary springs 115 are all fixedly connected to the outside of the first pair of joints 102; four sets of control push pins 116 are slidably connected to the outside of the connecting collar 114 in a circular array; support springs 121 are fixedly connected to the outside of the four sets of control push pins 116; the ends of the four sets of support springs 121 are all fixedly connected to the inside of the connecting collar 114; four locking grooves 117 are formed in a circular array on the outside of the connecting collar 114; four sets of mounting seats 118 are fixedly connected to the outside of the first pair of joints 102 in a circular array; a locking bracket 119 is rotatably connected to each of the four sets of mounting seats 118; the four locking brackets 119 are respectively engaged in the four locking grooves 117; a set of control torsion springs 120 are fixedly connected to the outside of the rotating shafts of the four locking brackets 119; the ends of the four sets of control torsion springs 120 are respectively fixedly connected to the four sets of mounting seats 118.

[0031] The specific usage and function of this embodiment: By inserting the first connector 102 into the second connector 103, the first cable body 1 and the second cable body 101 can be connected, facilitating quick connection of low-voltage power cables by the operator. As the first connector 102 is inserted into the second connector 103, the fixing block 104 will be inserted into the fixing slot 112. During the insertion of the fixing block 104 into the fixing slot 112, the fixing slot 112 will press against the limiting wedge 105, causing the limiting wedge 105 to slide within the fixing block 104 and press against the limiting spring 106. When the fixing block 104 is fully inserted into the fixing slot 112, the limiting wedge 105 just disengages from the fixing slot 112. At this time, the limiting wedge 105 will follow the limiting spring. The spring 106 returns to its original position, causing the limiting wedge 105 to engage outside the second connector 103, thus securing the mated first and second connectors 102 and 103. During the resetting process of the limiting wedge 105, it compresses the locking wedge 107, causing the locking wedge 107 to slide within the first connector 102 and compress the locking spring 108. After the limiting wedge 105 is fully reset, the locking wedge 107 is aligned with the pre-drilled groove on the limiting wedge 105. At this point, the limiting wedge 105 returns to its original position with the return of the locking spring 108, inserting into the pre-drilled groove, thus interlocking the locking wedge 107 with the limiting wedge 105. The reverse toothed anti-slip texture enhances the interlocking between the locking wedge 107 and the limiting wedge 105. To prevent loosening, pressing the control push seat 109 causes it to slide within the limiting wedge block 105, compressing the connecting spring 110. Since the control push seat 109 and the locking wedge block 107 are aligned, the sliding of the control push seat 109 compresses the locking wedge block 107, causing it to slide within the first coupling 102 and disengage from the limiting wedge block 105. Only then can the operator press the limiting wedge block 105 to release the fixation between the first coupling 102 and the second coupling 103. The length of the control push post 116 is greater than the height of the limiting wedge block 105, ensuring sufficient operating space between the connecting collar 114 and the limiting wedge block 105 even when the control push post 116 is inserted into the limiting wedge block 105. To facilitate pressing the limiting wedge 105, the auxiliary spring 115 is initially in a stretched state. By pressing the locking frame 119, the locking frame 119 rotates and twists the control torsion spring 120, causing the locking frame 119 to disengage from the locking groove 117. At this time, the connecting collar 114 will reset with the rebound of the auxiliary spring 115, allowing the control push post 116 to insert into the limiting wedge 105 and press the control push seat 109 to release the fixing of the limiting wedge 105, facilitating quick release of the limiting wedge 105 by the operator. When pressing the limiting wedge 105, the movement of the limiting wedge 105 causes the control push post 116 to slide within the connecting collar 114 and compress the support spring 121. All springs described in this application are made of 316 stainless steel.It features high elastic limit, stable fatigue strength, and is not prone to plastic deformation under long-term stress.

[0032] Example 2: Based on Example 1, please refer to Figures 1 to 5 It includes: positioning posts 113 and positioning grooves 111. The first pair of connectors 102 is fixedly connected to four positioning posts 113 in a ring array on the outside. All four positioning posts 113 are triangular prism structures. The second pair of connectors 103 is provided with four positioning grooves 111 in a ring array on the outside. The four positioning posts 113 are respectively inserted into the four positioning grooves 111.

[0033] The specific usage and function of this embodiment: The positioning post 113 and positioning groove 111 enable low-voltage power cables to achieve quick and accurate alignment, avoiding misalignment.
