If the two are far apart, the terminal connector body will be too large, wasting external installation space." However, after the connection structure in the above application is connected, the connection between the two ends is not stable enough, and it is easy to loosen after long-term use, which is inconvenient for staff to use.

[0025] The utility model provides a technical solution:

[0026] Embodiment 1

[0027] Combination Figures 1 to 4 A terminal connection structure of a connector includes a connector 3, a plug 4 is plugged into the right side of the connector 3, a plugging mechanism 1 is arranged in the connector 3, and a positioning mechanism 2 is arranged in the plug 4.

[0028] The plug-in mechanism 1 includes a plug-in component 11, a connecting component 12 and a telescopic component 13. The plug-in component 11 is arranged in the joint 3, the connecting component 12 is arranged at the upper and lower sides of the plug-in component 11, and the telescopic component 13 is arranged at the upper and lower sides of the joint 3.

[0029] The plug assembly 11 includes a card plate 1101, which is fixedly connected to the left side of the plug 4, and the card plate 1101 is clamped in the right side of the connector 3. The left side of the card plate 1101 is fixedly connected to a plug sheet 1102, and a plug plate 1103 is clamped in the left side of the plug sheet 1102. The plug plate 1103 is fixedly connected to the left side of the connector 3. The connection assembly 12 includes a contact plate 1201, which is arranged on the upper and lower sides of the plug sheet 1102, and a clamping protrusion 1202 is fixedly connected to the inner side of the contact plate 1201, and the clamping protrusion 1202 is clamped in the upper and lower sides of the plug sheet 1102. Inside, a return spring 1203 is fixedly connected to the outside of the contact plate 1201, and the return spring 1203 is fixedly connected to the upper and lower sides of the joint 3. The telescopic component 13 includes a fixed cylinder 1301, and the fixed cylinder 1301 is fixedly connected to the upper and lower sides of the joint 3 corresponding to the position of the return spring 1203. A slider 1302 is slidably connected to the fixed cylinder 1301, and a telescopic rod 1303 is fixedly connected to the inner side of the slider 1302. The telescopic rod 1303 is fixedly connected to the outside of the contact plate 1201, and the telescopic rod 1303 is slidably connected to the inner side of the fixed cylinder 1301.

[0030] Furthermore: after the connector 3 and the plug 4 are plugged in, the plug plate 1103 is first engaged with the left side of the plug 1102 to complete the preliminary connection between the connector 3 and the plug 4, and then the contact plate 1201 will drive the latch 1202 to engage with the upper and lower sides of the plug 1102 under the action of the reset spring 1203 to complete the complete connection between the connector 3 and the plug 4, thereby increasing the stability of the connection between the connector 3 and the plug 4 after being plugged in. When the connector 3 and the plug 4 are plugged in, the contact plate 1201 will not hinder the entry and exit of the plug 1102 due to the bevel angles set on the left and right sides.

[0031] Embodiment 2

[0032] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 On the basis of the first embodiment, it is further obtained that the positioning mechanism 2 includes a positioning component 21 and a disassembly component 22, the positioning component 21 is arranged on the right side of the plug-in component 11, and the disassembly component 22 is arranged on the front and rear sides of the connector 3.

[0033] The positioning component 21 includes a slide 2101, which is slidably connected to the front and rear sides of the card plate 1101, and a card block 2102 is fixedly connected to the outside of the slide 2101. The card block 2102 is clamped in the front and rear sides of the joint 3, and a compression spring 2103 is fixedly connected to the inside of the slide 2101. The disassembly component 22 includes a pressure rod 2201, and the inner side of the pressure rod 2201 is fitted with the outer side of the card block 2102. The pressure rod 2201 is slidably connected to the front and rear sides of the joint 3, and a connecting plate 2202 is fixedly connected to the outside of the pressure rod 2201. The connecting plate 2202 is slidably connected to the outside of the limiting slide frame 2203, and the limiting slide frame 2203 is fixedly connected to the front and rear sides of the joint 3.

[0034] Furthermore: after the connector 3 and the plug 4 are connected, the slide 2101 will drive the block 2102 to move outward under the action of the compression spring 2103 and be connected to the front and rear sides of the connector 3 to complete the fixation of the connector 3 and the plug 4, thereby increasing the stability of the connector 3 and the plug 4 after the connection. At the same time, the staff only needs to press the front and rear connecting plates 2202 inward to squeeze the front and rear blocks 2102 back into the card plate 1101 through the pressure rod 2201 to release the fixation between the connector 3 and the plug 4, so that the staff can quickly complete the disassembly and assembly between the connector 3 and the plug 4. The operation is simple and convenient for the staff to use.

[0035] In actual operation, when the device is used and the connector 3 and the plug 4 need to be connected, the staff first aligns the plug 4 and the connector 3, and then moves the plug 4 to the left to drive the plug 1102 into the connector 3, so that the plug plate 1103 is engaged with the left side of the plug 1102. In the process of the plug 1102 entering the connector 3 and moving to the left, the left end of the plug 1102 first contacts the inclined surface of the right end of the contact plate 1201, squeezing the contact plates 1201 on the upper and lower sides to move outward synchronously until the plug 1102 can no longer move to the left. At this time, the contact plate 1201 drives the clamping protrusion 1202 to move inward under the action of the reset spring 1203 and is engaged with the upper and lower sides of the plug 1102. At the same time, the inner side of the contact plate 1201 also fits with the upper and lower sides of the plug 1102. At this time, the connector 3 and the plug 4 are connected.

[0036] After the plug 4 and the connector 3 are connected, the slide 2101 drives the clamping block 2102 to move outwards under the action of the compression spring 2103 to clamp the connector 3 on both sides to fix the connector 3 and the plug 4. At this time, the connection between the connector 3 and the plug 4 is completed.

[0037] When it is necessary to disassemble the connector 3 and the plug 4, the staff first presses the connecting plates 2202 on the front and rear sides to move inwards. The connecting plates 2202 on the front and rear sides move inwards to drive the pressure rods 2201 on the front and rear sides to move inwards. The pressure rods 2201 on the front and rear sides move inwards to squeeze the card block 2102 to retract inward into the card plate 1101, so that the card plate 1101 is released from the connector 3. After that, the staff can directly move the plug 4 and the connector 3 to the left and right sides respectively to complete the disassembly of the connector 3 and the plug 4.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
