Description

Technical Field

[0001] The utility model relates to the technical field of wire terminals, in particular to a wire terminal with a protective structure. Background Art

[0002] Terminal strips are terminals with wire connections used in electronic equipment or circuits. Such terminals are usually used to connect power, signal and ground wires to effectively transmit current and signals. Terminal strips usually have connection methods such as screws or pins, which are convenient for users to connect wires to circuit boards or devices. Common types of terminal strips include socket terminals, some of which have their own protective structures to increase the safety of the device.

[0003] After searching, the applicant found that a Chinese patent disclosed "a plug terminal with a protective structure", and its publication (announcement) number is "CN215497342U". This patent mainly sets a positioning mechanism. The user inserts the plug body into the inner cavity of the socket body. When the positioning rod contacts the plug body, since the positioning rod is oblique, the socket body drives the positioning rod to move to the side close to the through hole, and the positioning rod drives the spring to deform under force. When the plug body moves to a certain position, the spring is deformed under force and drives the positioning rod to move to the side close to the positioning groove, so that the positioning rod is stuck in the inner cavity of the positioning groove. In the embodiment of the present invention, the plug body is limited in position to prevent the plug body from being separated from the inner cavity of the socket body when the wire is pulled, thereby preventing a power outage. When the plug body needs to be separated from the socket body, the user pulls the positioning rod to separate the positioning rod from the inner cavity of the positioning groove. At this time, the plug body is taken out. By setting a through hole, the positioning rod is easy to move. However, in the above comparative example, it is difficult to fix the position of the wires. In this way, the wires at both ends may fall off when being pulled, resulting in a power outage. For this reason, we propose a wire terminal with a protective structure. Utility Model Content

It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] Example 1, please refer to the attached Figure 1 -Attached Figure 4 The utility model provides a technical solution: a wire terminal with a protective structure, comprising a wiring terminal 1, a clamping structure 2 is arranged on the front of the wiring terminal 1, two groups of wiring terminals 1 are connected by a fixing structure 3, the clamping structure 2 comprises a limit frame 21, a movable plate 22, a mounting frame 23 and an electric push rod 24, the mounting frame 23 is mounted on both sides of the limit frame 21, one end of the electric push rod 24 is fixedly connected to the inner wall of the limit frame 21, and the other end of the electric push rod 24 extends to the inner wall of the limit frame 21 and is fixedly connected to one side of the movable plate 22.

[0022] Please see attached Figure 1 -Attached Figure 3 The inner wall of the limiting frame 21 is provided with a placement groove, and a plug-in groove is provided behind the placement groove. The movable plate 22 is placed on the inner wall of the placement groove and is slidably connected to the inner wall of the placement groove;

[0023] In this embodiment, the size of the clamping structure 2 changes with the size of the plug-in slot, and after the electric push rod 24 is fully unfolded, the space on the opposite side of the movable plate 22 is adapted to the plug-in slot, that is, after the wire is inserted into the plug-in slot, the movable plate 22 can fix it without causing damage to the wire. The clamping structure 2 can also be defined as a protective structure. The function of the clamping structure 2 is to reduce the problem of the wire falling off and causing power outage when being pulled.

[0024] When in use, one end of the wire is passed through the limit frame 21 and then inserted into the inner wall of the plug-in slot, and then the electric push rod 24 is started. At this time, the electric push rod 24 can push the movable plate 22 to move to the opposite side. The wire is now limited by the push plates on the left and right sides, thereby fixing the position of the wire, thereby reducing the problem of power failure caused by deviation when the wire is connected through the terminal block 1.

[0025] Example 2, please refer to the attached Figure 1 -Attached Figure 4 The utility model provides a technical solution: a wire terminal with a protective structure, comprising a wiring terminal 1, a clamping structure 2 is arranged on the front of the wiring terminal 1, two groups of wiring terminals 1 are connected by a fixing structure 3, the clamping structure 2 comprises a limit frame 21, a movable plate 22, a mounting frame 23 and an electric push rod 24, the mounting frame 23 is mounted on both sides of the limit frame 21, one end of the electric push rod 24 is fixedly connected to the inner wall of the limit frame 21, and the other end of the electric push rod 24 is extended to the inner wall of the limit frame 21 and fixedly connected to one side of the movable plate 22.

[0026] Please see attached Figure 4 The fixing structure 3 includes a fixing block 31 and a spring 32, one end of the spring 32 is fixedly connected to one end of the fixing block 31, the spring 32 is a spiral torsion spring, the other end of the fixing block 31 is arc-shaped, a mounting screw is provided on the top of the terminal block 1, a plug-in block 11 is provided on the inner wall of the terminal block 1, a through hole adapted to the fixing block 31 is provided on the outer surface of the terminal block 1, a circular hole is provided on the inner wall of the plug-in block 11, and the other end of the spring 32 is fixedly connected to the inner bottom wall of the circular hole.

[0027] In this embodiment, a hydraulic buffer rod is inserted into the inner wall of the spring 32. The function of the hydraulic buffer rod is to reduce the excessive deformation of the spring 32 and cause damage to the spring 32. When the two sets of terminals are spliced ​​and used, the fixed block 31 and the spring 32 are both subjected to extrusion force. When the fixed block 31 encounters the through hole during continuous pushing, the spring 32 and the fixed block 31 are no longer under force. At this time, the spring 32 drives the fixed block 31 to pop out, and the two sets of terminal blocks 1 are directly fixed by clamping the fixed block 31 with the through hole.

[0028] When in use, through the design of the fixing structure 3, when the two groups of terminal blocks 1 are connected, they are first fixed by plugging the back sides of the two groups of terminal blocks 1 through the plug-in blocks 11, and when the two groups of terminal blocks 1 are moved to the opposite side, the fixing block 31 is squeezed and deformed. At this time, the spring 32 drives the fixing block 31 to move backward. When the fixing block 31 encounters the through hole, the spring 32 drives the fixing block 31 to rebound without being subjected to force, and the two groups of terminal blocks 1 are fixed by the fixing block 31. During subsequent disassembly, it is only necessary to press the fixing block 31, and then pull the two groups of terminal blocks 1 in opposite directions to achieve quick disassembly, thereby achieving the effect of quick installation and quick disassembly.

[0029] Working principle:

[0030] The first step is to firstly connect and fix the back sides of the two groups of wiring terminals 1 through the plug-in blocks 11, and when the two groups of wiring terminals 1 are moved to the opposite side, the fixing blocks 31 are squeezed and deformed, and at this time, the spring 32 drives the fixing blocks 31 to move backward, and when the fixing blocks 31 encounter the through holes, the spring 32 drives the fixing blocks 31 to rebound without being subjected to force, and the two groups of wiring terminals 1 are fixed by the fixing blocks 31;

[0031] The second step, finally, is to pass the wire through the placement slot set in the limit frame 21, and extend it to the plug-in slot for fixation. At this time, start the electric push rod 24, which can drive the movable plate 22 to move. The two sets of movable plates 22 move to the opposite side to clamp the wire. At this point, the entire work process ends.
