Description

Technical Field

[0001] This utility model belongs to the field of electrical technology, and specifically relates to a line terminal. Background Technology

[0002] A terminal is a product used to transmit electrical energy or signals, and is commonly used for connecting electrical transmission components. There are many types of terminals, each with different uses. Common types include those for connecting cables to cables, those for connecting cables to electrical equipment, and those for connecting cables to other terminals. However, there is a lack of terminals for connecting cables to circuit boards. When connecting cables to circuit boards, sometimes it is necessary to transmit electrical energy or signals to the circuit board, and sometimes it is simply to fix the cable to the circuit board. If the cable and circuit board are directly soldered together, this connection method is rough and not only is it easy to fall off, but it is also inconvenient to replace the cable, requiring resoldering. This not only makes the entire assembly process cumbersome, but it is also very easy to damage the circuit board. Therefore, there is an urgent need for a new type of terminal in the existing technology to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a line terminal that can be used to connect cables to circuit boards and facilitate the disassembly of cables.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A line terminal includes a connecting post, the bottom end of the outer side of the connecting post being fixedly connected to the inner side of the connecting ring, the connecting ring being sleeved in a mounting groove, the mounting groove being formed on the upper surface of a fixing base, and a plurality of pins being fixedly disposed on the bottom surface of the fixing base.

[0006] A screw hole is provided in the middle of the connecting post, and the middle of the outer side of the connecting post is fixedly connected to the inner side of the convex ring.

[0007] The outer side of the connecting ring has two limiting planes, both of which overlap with the inner side of the mounting groove.

[0008] The inner side of the mounting groove is fixedly connected to one end of the limiting rod, and the limiting rod is sleeved in the connecting groove.

[0009] The connecting groove is formed at the bottom of the connecting ring.

[0010] The inner side of the connecting groove is simultaneously fixedly connected to one end of two elastic limiting plates, and the upper ends of the two elastic limiting plates overlap with the outer side of the limiting rod.

[0011] The technical effects achieved by this utility model are as follows:

[0012] In use, the pins at the bottom of the mounting base can be inserted into the corresponding holes on the circuit board to connect the mounting base to the circuit board. Then, the connecting ring can be inserted into the mounting groove, and the limiting rod can be inserted into the connecting groove to limit the connecting post, thereby connecting the connecting post to the mounting base. The user can then thread the cable end into the screw hole to electrically connect the cable to the circuit board. This facilitates the user's subsequent disassembly and replacement of the cable. Furthermore, the connecting ring, mounting groove, limiting rod, and connecting groove connect the connecting post to the mounting base, making it easy for the user to disassemble the mounting base. This allows for the replacement of mounting bases with compatible pins according to the number and arrangement of the connecting holes on the circuit board, thus effectively improving the applicability of the device.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0019] like Figure 1-3 As shown, a line terminal includes a connecting post 1. The bottom end of the outer side of the connecting post 1 is fixedly connected to the inner side of the connecting ring 7. The connecting ring 7 is sleeved in the mounting groove 5. The mounting groove 5 is opened on the upper surface of the fixing base 3. A plurality of pins 4 are fixedly provided on the bottom surface of the fixing base 3. By providing a plurality of pins 4 on the bottom surface of the fixing base 3, the pins 4 provided on the bottom of the fixing base 3 can be inserted into the corresponding holes on the circuit board during use, thereby connecting the fixing base 3 to the circuit board.

[0020] Furthermore, a screw hole 11 is provided in the middle of the connecting post 1, and the middle of the outer side of the connecting post 1 is fixedly connected to the inner side of the convex ring 2. By providing a convex ring 2 on the outside of the connecting post 1, a groove formed between the convex ring 2 and the connecting ring 7 can be fitted with a cable, so as to fix multiple cables on the circuit board.

[0021] Furthermore, two limiting planes 8 are provided on the outer side of the connecting ring 7. Both limiting planes 8 overlap with the inner side of the mounting groove 5. By providing limiting planes 8 on the outer side of the connecting ring 7, the movement of the connecting column 1 is restricted by the fit between the limiting planes 8 and the matching mounting groove 5 to prevent the connecting column 1 from rotating.

[0022] Furthermore, the inner side of the mounting groove 5 is fixedly connected to one end of the limiting rod 6, and the limiting rod 6 is sleeved in the connecting groove 9.

[0023] Furthermore, the connecting groove 9 is formed at the bottom of the connecting ring 7.

[0024] Furthermore, the inner side of the connecting groove 9 is simultaneously fixedly connected to one end of two elastic limiting plates 10. The upper ends of the two elastic limiting plates 10 overlap with the outer side of the limiting rod 6. When connecting the connecting column 1 to the fixed seat 3, the connecting ring 7 is inserted into the mounting groove 5 from top to bottom, and the limiting rod 6 corresponds to the connecting groove 9. As the connecting column 1 continues to descend, the limiting rod 6 squeezes the elastic limiting plate 10 and moves it into the connecting groove 9. When the bottom end of the connecting ring 7 contacts the bottom end of the mounting groove 5, the limiting rod 6 moves to the upper end of the elastic limiting plate 10. The elastic limiting plate 10 uses its elasticity to restore its original shape to limit the limiting rod 6, thereby restricting the up and down movement of the connecting column 1 and preventing the connecting column 1 from separating from the fixed seat 3.

[0025] The working principle of this utility model is as follows: When using this device to connect the cable to the circuit board, the user can first select the fixing seat 3 with corresponding pins 4 according to the specifications of the connection hole on the circuit board, and then insert the connecting ring 7 into the mounting groove 5 from top to bottom, so that the limiting rod 6 corresponds to the connecting groove 9. As the connecting post 1 continues to descend, the limiting rod 6 squeezes the elastic limiting piece 10 and moves it into the connecting groove 9. When the bottom end of the connecting ring 7 contacts the bottom end of the mounting groove 5, the limiting rod 6 moves to the upper end of the elastic limiting piece 10. The elastic limiting piece 10 uses its elasticity to restore its original shape to limit the limiting rod 6. Then the user can insert the pin 4 into the connection hole on the circuit board and screw the cable end to the screw hole 11.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
