Description

Technical Field

[0001] The utility model relates to the technical field of multi-interface modular wiring terminals, in particular to a multi-interface modular wiring terminal. Background Art

[0002] Multi-interface modular terminal blocks are devices used to connect multiple wires or cables. They are usually used in electronic equipment, communication equipment, control systems and other fields. This type of terminal block has multiple interfaces and can connect multiple wires at the same time to achieve signal transmission or power transmission.

[0003] The existing related technologies often have the following defects: in the process of installing the wires inside the multi-interface modular terminal block, the multi-interface modular terminal block often uses screws to tighten the wire cores of the wires, which requires the use of external tools such as screwdrivers. The screws are prone to wear at the screwing position during long-term twisting, which makes it inconvenient to subsequently install and fix the wires inside the multi-interface modular terminal block.

[0004] Therefore, the utility model provides a multi-interface modular wiring terminal. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a multi-interface modular terminal block, comprising a shell, a first copper sheet frame and a second copper sheet frame are fixedly installed on the inner side of the shell, an insulating pressure plate frame is fixedly installed on the outer side of the shell, two push blocks are fixedly installed on the inner side of the insulating pressure plate frame, the lower end of the first copper sheet frame is a "V"-shaped structure, and four sockets are evenly opened on the lower surface of the shell.

[0007] The effect achieved by the above components is: put the core of the wire between the first copper sheet frame and the second copper sheet frame, loosen the insulating pressure plate frame, then the push block will be lifted, and the first copper sheet frame will be pressed against the second copper sheet frame by its own elastic force.

[0008] Preferably, a plurality of anti-slip grooves are evenly arranged on the side wall of the second copper sheet rack.

[0009] The effects achieved by the above components are as follows: the anti-slip grooves provided on the second copper sheet frame increase the friction between the second copper sheet frame and the wire core during movement, thereby improving the stability of fixing the wire core.

[0010] Preferably, a plurality of rectangular blocks are evenly and fixedly connected to the lower surface of the shell, and the rectangular blocks are grouped in pairs. A sliding frame is slidably connected to the inside of the rectangular blocks, and a limiting frame is fixedly connected to the surface of the sliding frame. A rotating shaft is rotatably connected to the inside of the limiting frame, and a limiting wheel is fixedly connected to the side wall of the rotating shaft. A plurality of barbs are fixedly connected to the side wall of the limiting wheel, and the barbs are arc-shaped structures.

[0011] The effect achieved by the above components is that when the electric wire is subjected to external force, the surface of the electric wire will be sheathed inside the barb, thereby preventing the electric wire from continuing to be pulled down.

[0012] Preferably, the internal threads of the sliding frame are connected with bolts.

[0013] The effect achieved by the above components is that the rotating bolt is pressed against the side wall of the rotating shaft, so that the position of the limiting wheel can be fixed after rotation.

[0014] Preferably, a spring is fixedly connected to one side of the limit frame and the rectangular block that are close to each other.

[0015] The effect achieved by the above components is that the limiting wheel is pressed against the surface of the wire by the elastic force of the spring between the rectangular block and the sliding frame.

[0016] Preferably, a rotating block is fixedly mounted on the end side of the rotating shaft, and the side wall of the rotating block is provided with anti-slip grooves.

[0017] The effect achieved by the above components is: the rotating block moves, and the rotating block drives the rotating shaft to rotate.

[0018] Preferably, a plurality of connection plates are fixedly connected to the surface of the shell, and a limiting ring is fixedly connected to the side wall of the connection plate.

[0019] The effect achieved by the above components is: the stripped wire of the port is inserted from the position of the limiting ring, and the setting of the limiting ring prevents the wire from shaking significantly between the two limiting wheels.

[0020] In summary:

[0021] In the utility model, by setting the above-mentioned structure, the traditional method of fixing the wires with screws is changed. Under the premise of ensuring the stability of the fixation of the wires, the efficiency of fixing the internal wires of the multi-interface modular terminal block is improved, the disassembly and assembly of the internal wires of the multi-interface modular terminal block is facilitated, and the performance of the multi-interface modular terminal block is improved to a certain extent.

[0029] Reference Figure 1-6 As shown, the utility model provides a technical solution: a multi-interface modular terminal block, comprising a housing 1, on the inner side of which a first copper sheet frame 4 and a second copper sheet frame 5 are fixedly mounted.

[0030] The following is a detailed description of its overall specific settings and functions.

[0031] In this embodiment: an insulating plate frame 2 is fixedly installed on the outer side of the housing 1, two push blocks 3 are fixedly installed on the inner side of the insulating plate frame 2, the lower end of the first copper sheet frame 4 is a "V"-shaped structure, and four sockets 8 are evenly opened on the lower surface of the housing 1. The core of the wire is put between the first copper sheet frame 4 and the second copper sheet frame 5, and the insulating plate frame 2 is released. At this time, the push block 3 will be lifted, and the first copper sheet frame 4 will be pressed on the second copper sheet frame 5 by its own elastic force.

[0032] The side wall of the second copper sheet frame 5 is evenly provided with a plurality of anti-skid grooves 18. The anti-skid grooves 18 provided on the second copper sheet frame 5 increase the friction force during the movement between the wire core and the wire core, and improve the stability of fixing the wire core. The lower surface of the housing 1 is evenly fixedly connected with a plurality of rectangular blocks 9, and the plurality of rectangular blocks 9 are grouped in pairs. The interior of the rectangular blocks 9 is slidably connected with a sliding frame 10, and the surface of the sliding frame 10 is fixedly connected with a limit frame 11, and the interior of the limit frame 11 is rotatably connected with a rotating shaft 13, and the side wall of the rotating shaft 13 is fixedly connected with a limit wheel 14, and the side wall of the limit wheel 14 is fixedly connected with a plurality of barbs 15, and the barbs 15 are arc-shaped structures. When the wire is subjected to external force, the skin of the wire will be sheathed inside the barbs 15, which can prevent the wire from continuing to be pulled down.

[0033] The inner thread of the sliding frame 10 is connected with a bolt 17. The bolt 17 is rotated to squeeze the side wall of the rotating shaft 13, so as to fix the position of the limit wheel 14 after rotation. The limit frame 11 and the rectangular block 9 are fixedly connected to the side where they are close to each other with a spring 12. The limit wheel 14 is pressed against the surface of the wire by the elastic force of the spring 12 between the rectangular block 9 and the sliding frame 10.

[0034] Specifically, a rotating block 16 is fixedly installed on the end side of the rotating shaft 13, and the side wall of the rotating block 16 is provided with anti-slip grooves. When the rotating block 16 is moved, the rotating block 16 will drive the rotating shaft 13 to rotate. A plurality of connecting plates 6 are fixedly connected to the surface of the housing 1, and the side wall of the connecting plate 6 is fixedly connected to the limiting ring 7. The stripped wire of the port is inserted from the position of the limiting ring 7. The setting of the limiting ring 7 prevents the wire from shaking greatly between the two limiting wheels 14.

[0035] Working principle: rotating the rotating block 16, the rotating block 16 will drive the rotating shaft 13 to rotate, and the rotating shaft 13 will drive the limiting wheel 14 to rotate. When the barbs 15 set on the two limiting wheels 14 are rotated to a position close to each other, the rotating bolt 17 is squeezed on the side wall of the rotating shaft 13, and the position of the limiting wheel 14 after rotation can be fixed. When the wire needs to be installed on the inner side of the multi-interface modular terminal, the stripped wire of the port is inserted from the position of the limiting ring 7, and the limiting ring 7 The arrangement prevents the wire from shaking significantly between the two limit wheels 14. The insulating pressure plate frame 2 is pressed. At this time, the push block 3 will push the first copper sheet frame 4 and the second copper sheet frame 5 to open a certain gap, and the wire core of the wire is sleeved between the first copper sheet frame 4 and the second copper sheet frame 5. The insulating pressure plate frame 2 is released. At this time, the push block 3 will be lifted, and the first copper sheet frame 4 will be pressed against the second copper sheet frame 5 by its own elastic force. The anti-slip groove 18 provided on the second copper sheet frame 5 increases the friction between the wire core and the wire core during movement. The friction force improves the stability of fixing the wire core, and the wire core can be quickly fixed at this time. In the process of sliding the wire, the skin of the wire will be sheathed in the position between the two limiting wheels 14, and the limiting wheel 14 will be pressed against the surface of the skin of the wire by the elastic force of the spring 12 between the rectangular block 9 and the sliding frame 10. When the wire is subjected to external force, the skin of the wire will be sheathed inside the barb 15, which can avoid the continued pulling down of the wire, thereby improving the stability of using the wire inside the terminal. When the wire needs to be disassembled, the limiting wheel 14 can be rotated to rotate the barb 15 on the limiting wheel 14 out of the skin of the wire, which facilitates the subsequent extraction of the wire. By setting the above structure, the traditional method of fixing the wire with screws is changed. Under the premise of ensuring the stability of fixing the wire, the efficiency of fixing the internal wires of the multi-interface modular terminal is improved, the disassembly and assembly of the internal wires of the multi-interface modular terminal is facilitated, and the use performance of the multi-interface modular terminal is improved to a certain extent.
