Description

Technical Field

[0001] This utility model relates to the field of circuit connection technology, specifically a connection device for connecting wires and terminals. Background Technology

[0002] In modern electronic devices and electrical systems, reliable connection between wires and terminals is a key factor in ensuring stable system operation. Currently, common terminal connection devices mostly use single fixing methods such as crimping and screws to connect wires and terminals. However, existing connection devices still have certain defects in practical applications. In particular, during the connection process, when frequently plugged and unplugged or subjected to external force, the connection stability between the terminal and the wire is insufficient, which can easily lead to detachment or increased contact resistance, thereby affecting the normal operation of the equipment and even causing safety hazards. In addition, some connection devices have relatively simple structural designs and lack effective anti-loosening and fixing structures, making them unable to adapt to complex and changing usage environments.

[0003] To address the aforementioned problems, this utility model proposes an improved connecting wire terminal device, aiming to enhance the reliability and stability of the connection and avoid malfunctions caused by loose connections or detachment due to force. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, this utility model provides a technical solution: a connecting wire terminal connection device, including a terminal base 1, a female connector slot 101, a connecting seat 102, a wire insertion groove 103, a plug 104, and a connecting wire 105. The female connector slot 101 is fixedly installed on the upper wall of the terminal base 1, and the connecting seat 102 is fixedly installed on the upper end of the terminal base 1. Multiple sets of wire insertion grooves 103 are equidistantly opened on the outer wall of the connecting seat 102. The plug 104 is inserted into the multiple sets of wire insertion grooves 103, and the connecting wire 105 is fixedly connected to the outer end of the plug 104.

[0025] The front wall of the connector 102 is provided with multiple sets of connecting thread grooves 2 at equal intervals. Connecting screws 201 are inserted inside the multiple sets of connecting thread grooves 2. A fixing head 202 is sleeved on the outside of the connecting screws 201. A fixing component is provided at one end of the fixing head 202.

[0026] The fixing assembly includes a fixing ring 203 connected to the right end of the fixing tube of the fixing head 202. The outer wall of the fixing ring 203 has an installation groove 206. The outer wall of the fixing ring 203 has four sets of sliding grooves. A fixing block 205 is installed inside each of the four sets of sliding grooves. A ring spring 207 is installed inside the mounting groove 206. The outer wall of the fixing ring 203 has four sets of actuating grooves 208. A actuating block 211 is fixedly connected to one end of the fixing block 205. The width of the actuating block 211 is greater than the depth of the actuating groove 208. The lower wall of the actuating block 211 has anti-slip texture. The front wall of the fixing ring 203 is provided with four sets of limiting components. The four sets of limiting components are used to limit the actuation distance of the stop bar 210.

[0027] Based on the overall structure of the device, the structural design is optimized to enhance the fixing effect between the connection terminal and the connection line 105, effectively preventing the connection from loosening or falling off due to frequent plugging and unplugging or external pulling, thereby improving the overall connection stability. At the same time, the improved device has a more effective anti-loosening structure, which can adapt to a variety of complex operating environments and ensure the safety and continuity of equipment operation.

[0028] like Figure 2 As shown, the fixing head 202 consists of two parts: a connecting tube with a threaded slot on the left wall and a set of fixing tubes. The connecting wire 105 passes through the inside of the fixing tube of the fixing head 202, and the connecting screw 201 is rotatably inserted into the connecting tube of the fixing head 202.

[0029] By designing the fixing head 202 into two parts, one part is used to fix the fixing head 202 onto the connector 102, and the other part is used to fix the connecting wire 105.

[0030] like Figure 4 As shown, the height of the four sets of fixing blocks 205 is greater than the radius of the inner ring of the fixing ring 203, and the upper wall of the fixing block 205 is provided with a semi-circular groove.

[0031] By designing the height of the fixing block 205 to be greater than the radius of the inner ring of the fixing ring 203, the fixing block 205 will not fall out of the inner ring of the fixing ring 203 when it is not subjected to elastic force. When it is not subjected to elastic force, the four sets of fixing blocks 205 will be squeezed together. When in use, the toggle block 211 is moved to move the fixing block 205 to limit the connection line 105.

[0032] like Figure 5As shown, the fixing block 205 is made of polystyrene.

[0033] By designing the material of the fixing block 205 as polystyrene, it is not only lower in cost and easier to process, making it suitable for mass production, but also relatively hard and has good electrical insulation properties.

[0034] like Figure 3 As shown, a protective ring 204 is fitted on the outer wall of the fixing ring 203. A cylindrical slot is opened inside the protective ring 204, and the overall shape of the protective ring 204 is annular.

[0035] By providing a protective ring 204 around the fixed ring 203, the ring spring 207 can be limited by the protective ring 204, preventing the ring spring 207 from moving out of the mounting groove 206.

[0036] like Figure 4 As shown, the limiting assembly includes a fixed shaft 209 fixedly installed on the outer wall of a fixed ring 203. A stop bar 210 is sleeved on the outside of the fixed shaft 209. Part of the stop bar 210 is a collar and the other part is a crossbar. Two sets of fixing grooves 212 are opened on the outer wall of the stop bar 210. A set of plugs 213 are inserted into the inside of the fixing grooves 212. Multiple sets of limiting slots with the same size as the outer diameter of the fixing grooves 212 are opened on the outer wall of the fixed ring 203.

[0037] By using the limiting component, when it is necessary to insert the connecting wire 105 into the inside of the fixing ring 203 for fixing, the toggle block 211 can be moved upward, and then the limiting component can be used to temporarily restrict the toggle block 211 to prevent it from rebounding. After connecting the connecting wire 105, the limiting component can be released to fix the connecting wire 105.

[0038] Working principle: This device can fix the connecting wire 105 to be wired, enhancing the fixing effect between the connecting terminal and the connecting wire 105, and greatly preventing loosening caused by external pulling. When wiring, first rotate the connecting screw 201 into the connecting thread groove 2, then put the fixing head 202 on the outside of the connecting screw 201, then pass the connecting wire 105 through the fixing ring 203 and the fixing tube of the fixing head 202, then connect the plug 104 to one end of the connecting wire 105, and finally connect it to the wire slot 103. When the connecting wire 105 passes through the fixing ring 203, the actuating block 211 needs to be turned to drive the fixing block 205 upward, then the stop bar 210 is rotated to the bottom of the actuating block 211 and inserted into the plug 213 for fixing. After using the method to push all four sets of connecting wires 105 upwards, the connecting wire 105 can be inserted. After the connecting wire 105 is inserted, the plug 213 is pulled out, and then the stop lever 210 is pushed in the opposite direction. The fixing block 205 will be rebounded by the elastic force of the ring spring 207. At the same time, the height of the fixing block 205 is greater than the depth of the pushing groove 208. The four sets of fixing blocks 205 will tightly squeeze and fix the connecting wire 105 inside the fixing ring 203. When the connecting wire 105 is pulled by an external force, because the fixing ring 203 is connected to the fixing head 202, and the fixing head 202 is connected to the connecting screw 201, part of the force will be offset by the fixing head 202 and applied to the entire terminal block, not to the connection of the line. This ensures that it will not easily loosen when pulled by an external force.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
